[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-298154 [Summary of the Invention] [Problems to be Solved by the Invention]

[0005] In the wiring and pipe material fixture (wiring and pipe material holder) of Patent Document 1, the lower protruding piece of the other gripping piece is inserted into the gap between the upper protruding piece and the lower protruding piece of one gripping piece, and the upper protruding piece of one gripping piece is inserted into the gap between the upper protruding piece and the lower protruding piece of the other gripping piece, thereby forming a locked state between the locking tooth rows and firmly clamping the wiring and pipe materials with a pair of gripping pieces. However, in order to firmly maintain the locked state between the locking tooth rows, the gap between the upper protruding piece and the lower protruding piece of each gripping piece needs to correspond to the thickness of the protruding piece to be sandwiched, so it cannot be made sufficiently large. Also, due to deformation during storage or over time of the wiring and pipe material fixture, the opening between the upper protruding piece and the lower protruding piece of each gripping piece may narrow. Therefore, in the operation of engaging a pair of gripping pieces to grip the wiring and pipe materials, the process of inserting the two protruding pieces into the two narrow openings is not easy for the user. Also, in this operation, it is necessary for the user to hold the wiring and pipe materials or the wiring and pipe material holder while aligning the pair of gripping pieces. Therefore, it is an issue that the operation of the conventional wiring and pipe material holder is difficult.

[0006] The present invention has been made to solve the above problems, and its object is to provide a wiring and pipe material holder that can stably maintain the holding state of the wiring and pipe materials and can hold the wiring and pipe materials with a simpler operation. [Means for Solving the Problems]

[0007] The wiring and pipe material holder according to claim 1 is a wiring and pipe material holder for holding wiring and pipe materials, and A first holding piece extending from a base end to a tip end; A second holding piece extending from a base end to a tip end and connected to the first holding piece so as to cooperate with the first holding piece to surround a wiring or pipe material and hold it along the laying direction, An annular holding space surrounding the wiring or pipe material is formed by the tip end portion of the first holding piece and the tip end portion of the second holding piece overlapping each other, The second holding piece is displaceable relative to the first holding piece so as to overlap the first holding piece from the outside of the holding space, On the outer surface of the first holding piece and the inner surface of the second holding piece, a first locking portion and a second locking portion are provided to lock to each other so as to maintain the overlap of the first holding piece and the second holding piece, When the overlapping amount of the first holding piece and the second holding piece increases, the locking amount of the first locking portion and the second locking portion increases, or the relative locking positions of the first locking portion and the second locking portion change, The first locking portion and the second locking portion are configured to be unlocked by separating from each other in a direction different from the locking direction, At the tip end portion of the second holding piece, two separating pieces having free ends independent of each other are formed side by side in a width direction orthogonal to the extending direction of the second holding piece, and the second locking portion is provided on each of the two separating pieces, Both of the two separation pieces can be locked to the first locking part provided on the outer surface of the first holding piece. The second locking portion of one separating piece and the second locking portion of the other separating piece can independently form a locked state with the first locking portion and are Individually characterized in that they are separable from the first locking portion.

[0008] The wiring or pipe material holder according to claim 2, wherein, in the wiring or pipe material holder according to claim 1, on the outer surface of the tip end portion of the first holding piece, a dividing wall that at least partially divides the first locking portion is erected in a width direction orthogonal to the extending direction of the first holding piece, When the tip end portion of the first holding piece and the tip end portion of the second holding piece are overlapped, the dividing wall is inserted into a dividing groove between the two separating pieces.

[0009] The wiring and pipe material holder according to claim 3 is the wiring and pipe material holder according to claim 2, wherein a tapered guide edge portion is formed at the tip of the partition wall.

[0010] The wiring and pipe material holder according to claim 4 is the wiring and pipe material holder according to claim 2 or 3, wherein guide protrusions protruding from the inner surface of each separation piece toward the inside of the holding space are formed on each separation piece. Guide passages having a width into which the guide protrusions can enter are respectively formed between both side portions in the width direction of the partition wall and the first locking portion, and the guide passages extend along the advancing direction in which the overlapping amount of the first holding piece and the second holding piece is increased.

[0011] The wiring and pipe material holder according to claim 5 is the wiring and pipe material holder according to any one of claims 2 to 4, wherein a connecting piece formed for connecting one wiring and pipe material holder and another wiring and pipe material holder adjacent to the one wiring and pipe material holder in an arrangement direction intersecting the arrangement direction is provided at the top of the partition wall, and the connecting piece is spaced apart from the tip portion of the first holding piece so as not to interfere with the space in which the second holding piece can advance when overlapping the first holding piece.

[0012] The wiring and pipe material holder according to claim 6 is the wiring and pipe material holder according to any one of claims 1 to 5, wherein guide protrusions protruding from the inner surface of each of the two separation pieces toward the inside of the holding space are respectively formed on the two separation pieces. On the first holding piece, restricting portions are formed which respectively engage with the two guide protrusions from the width direction orthogonal to the extending direction of the first holding piece and restrict relative movement in a direction orthogonal to the advancing direction of the overlapping of the first holding piece and the second holding piece.

Advantages of the Invention

[0013] According to the wiring and pipe material holder described in claim 1, an annular holding space for surrounding the wiring and pipe material is formed by the tip portions of the first holding piece and the second holding piece overlapping each other. In particular, by displacing the second holding piece so as to overlap the first holding piece from the outside of the holding space, the locking states of the first locking portion on the outer surface of the second holding piece and the second locking portion on the inner surface of the second holding piece are formed and maintained. That is, it becomes possible to hold the wiring and pipe material with the first holding piece and the second holding piece by a simple and intuitive operation of overlapping the second holding piece on the first holding piece from the outside of the holding space. On the other hand, the first locking portion and the second locking portion are relatively easily unlocked by separating from each other in a direction different from the locking direction. In contrast, in the present invention, two separating pieces having free ends independent of each other are arranged in parallel at the tip portion of the second holding piece, and the second locking portion is provided on each separating piece, thereby preventing the first locking portion and the second locking portion from being inadvertently and easily unlocked. That is, the second locking portion of one separating piece and the second locking portion of the other separating piece can independently form a locking state with the first locking portion and can be separated from the first locking portion. That is, in order to release the holding of the wiring and pipe material, it is necessary to operate the two separating pieces so that the second locking portion is separated from the first locking portion respectively. Even if a force in the direction of separating the first locking portion and the second locking portion is unexpectedly applied to one of the two separating pieces and the locking state is released, since the locking state of the other separating piece is maintained, it is suppressed that the holding of the wiring and pipe material is completely released. Since the situation where a force in the direction of separating the first locking portion and the second locking portion is unexpectedly applied to both of the two separating pieces is extremely rare, the configuration of the present invention effectively prevents the holding of the wiring and pipe material from being inadvertently released. Therefore, the wiring and pipe material holder of the present invention can stably maintain the holding state of the wiring and pipe material and enables the wiring and pipe material to be held with a simpler operation.

[0014] According to the wiring and pipe material holder described in claim 2, in addition to the effects of the invention of claim 1, when the tip portions of the first holding piece and the second holding piece are superposed, the partition wall is inserted into the partition groove between the two separating pieces, so that the partition wall functions to regulate the two separating pieces from approaching each other in the width direction. That is, it is possible to prevent the locking state from being weakened due to the displacement of the separating piece, or the separating piece from sliding in the width direction and being unexpectedly unlocked.

[0015] According to the wiring and pipe material holder described in claim 3, in addition to the effects of the invention of claim 2, when the tapered guide edge portion is guided into the partition groove, the superposition operation of the first holding piece and the second holding piece becomes easy.

[0016] According to the wiring and pipe material holder described in claim 4, in addition to the effects of the invention of claim 2 or 3, in the operation of advancing the superposition of the first holding piece and the second holding piece, the guide protrusions of the respective separating pieces slide along the guide passage. Then, by maintaining the guide protrusions in the guide passage, it is possible to prevent the respective separating pieces from shifting in the width direction.

[0017] According to the wiring and pipe material holder described in claim 5, in addition to the effects of any one of the inventions of claims 2 to 4, it is possible to connect one wiring and pipe material holder and another wiring and pipe material holder via a connecting piece. Further, the connecting piece is positioned away from the tip portion of the first holding piece so as not to interfere with the advancing direction of the second holding piece, thereby preventing the superposition of the first holding piece and the second holding piece from being hindered.

[0018] According to the wiring and pipe material holder described in claim 6, in addition to the effects of any one of the inventions of claims 1 to 5, when the tip portions of the first holding piece and the second holding piece are superposed, the guide protrusions engage with the regulating portions from the width direction, thereby regulating the displacement of the respective separating pieces in the width direction.

Mode for Carrying Out the Invention

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the shapes of the respective figures referred to in the following description are conceptual diagrams or schematic diagrams for explaining suitable shape dimensions, and the dimensional ratios etc. do not necessarily coincide with the actual dimensional ratios. That is, the present invention is not limited to the dimensional ratios in the drawings. Also, the up-down, left-right directions in the present invention are merely concepts indicating relative positions, and it goes without saying that these can be interchanged and applied.

[0021] [First Embodiment] The wiring and pipe material holder 100 according to an embodiment of the present invention is fixed to a structure such as a building material or a wall material and is used for laying wiring and pipe materials with respect to the structure. In the present embodiment, the structure to which the wiring and pipe material holder 100 is fixed is a building material 11 having an installation surface (or a laying surface) on one side, and the wiring and pipe material P is exemplified as a corrugated flexible pipe. The wiring and pipe material P is formed such that ridges (large-diameter portions) and valleys (small-diameter portions) are alternately continuous in the longitudinal direction. However, it goes without saying that the present embodiment is merely an example of the present invention, and the use and configuration thereof are not limited as long as they do not depart from the technical scope of the present invention. Hereinafter, the configuration of the wiring and pipe material holder 100 of the present invention will be described.

[0022] Figs. 1(a) and (b) are perspective views of the wiring and pipe material holder 100 according to an embodiment of the present invention. Fig. 2 is a front view of the wiring and pipe material holder 100. Figs. 3(a) to (d) are a plan view, a left side view, a right side view, and a bottom view of the wiring and pipe material holder 100. Figs. 4 to 7 are cross-sectional views of respective portions of the wiring and pipe material holder 100.

[0023] The wiring and pipe material holder 100 of the present embodiment is fixed to a structure and is configured to lay the wiring and pipe material P along the wall surface of the structure in a predetermined laying direction by holding or gripping the wiring and pipe material P in a holding space 101 as a holding portion. As shown in Fig. 2, the wiring and pipe material holder 100 has a substantially C-shaped configuration so as to define the holding space 101 opened at an opening portion 103 in a front view. In the present embodiment, the wiring and pipe material holder 100 is integrally formed of a synthetic resin and has flexibility and elasticity in a band-shaped formed portion. Here, the holding space 101 means a region where the wiring and pipe material P having a predetermined diameter as a holding target is held, but may also be interpreted as a region where its outer edge varies according to the diameter (corresponding minimum diameter to opposing maximum diameter) of the wiring and pipe material P to be held.

[0024] In addition, the wiring and pipe material holder 100 is configured to be able to hold two or more types of wiring and pipe materials having different diameters from the minimum diameter to the maximum diameter in the holding space 101. Here, among the corresponding wiring and pipe materials P, the wiring and pipe material with the corresponding maximum diameter is represented by PL, the wiring and pipe material with the corresponding minimum diameter is represented by PS, and the wiring and pipe material with the diameter not specified is represented by P. Also, the corresponding maximum diameter of the wiring and pipe material is determined by the diameter of the longest body that can surround its outer peripheral surface in the (closed) holding space 101. On the other hand, the corresponding minimum diameter of the wiring and pipe material is determined by the diameter of the shortest body that can grip the wiring and pipe material in a state where it does not move in the holding space 101. Also, the diameter of the wiring and pipe material referred to here, in the case of a corrugated flexible pipe, is the outer diameter of the crest portion.

[0025] The wiring and pipe material holder 100 of the present embodiment includes a first holding piece 110 extending from the base end to the tip end, a second holding piece 120 extending from the base end to the tip end, cooperating with the first holding piece 110 to surround the wiring and pipe material P and hold it along the laying direction, a hinge 130 rotatably connecting the base end side of the first holding piece 110 and the base end side of the second holding piece 120 to each other, and an auxiliary piece 140 rising from the inner surface of the first holding piece 110 with the tip end as a free end. In the wiring and pipe material holder 100 of the present embodiment, the first holding piece 110, the second holding piece 120, the hinge 130, and the auxiliary piece 140 are integrally formed. Here, the direction in which the wiring and pipe material holder 100 (the first holding piece 110 and the second holding piece 120) extends in a C shape or an annular shape (the direction surrounding the wiring and pipe material P) is defined as the extending direction or the circumferential direction, and the inside-outside direction of the holding space 101 (the radial direction of the wiring and pipe material P) is defined as the radial direction. Also, the direction orthogonal to the extending direction of the wiring and pipe material holder 100 (the first holding piece 110 and the second holding piece 120) (the laying direction of the wiring and pipe material P) is defined as the width direction. Furthermore, the vertical direction in the front view perpendicular to the bottom surface (the fixed surface 111c) of the wiring and pipe material holder 100 is defined as the standing direction.

[0026] As shown in FIGS. 1 to 3, in the original form of the wiring and pipe material holder 100 (which does not hold the wiring and pipe material P), an opening 103 for introducing the wiring and pipe material P inward is formed between the tip of the first holding piece 110 and the tip of the second holding piece 120. Communicating with the opening 103, a holding space 101 for holding the wiring and pipe material P is defined inside the first holding piece 110 and the second holding piece 120. Then, with the hinge 130 as the center, the first holding piece 110 and the second holding piece 120 rotate or displace relative to each other, and when the tip portion of the first holding piece 110 and the tip portion of the second holding piece 120 overlap, an annular holding space 101 that surrounds the wiring and pipe material P in the circumferential direction can be formed. At this time, the second holding piece 120 overlaps the first holding piece 110 from the outside (radial outside) of the holding space 101. This closed holding space 101 can be maintained by the engagement of the first locking portion (first locking tooth row 113) of the first holding piece 110 and the second locking portion (second locking tooth row 123) of the second holding piece 120. The first locking portion and the second locking portion are disengaged by separating from each other in a direction different from the locking direction (that is, the radial direction). Further, in either the open or closed state of the opening 103, a hinge-side space 105 is formed as an extra gap where the wiring and pipe material P is not disposed between the holding space 101 and the hinge 130.

[0027] Since this hinge-side space 105 is a space for allowing the bending displacement of the base ends of the first holding piece 110 and the second holding piece 120 centered on the hinge 130, it is inevitably formed inside the wiring and pipe material holder 100. In conventional wiring and pipe material holders, such a hinge-side space may act as a relief space that causes bending deformation and displacement of the wiring and pipe material when the wiring and pipe material P is tightened with a relatively strong pressing force, resulting in problems in the installation of the wiring and pipe material P.

[0028] Further, while maintaining the locked state, the wiring and pipe material holder 100 can gradually reduce the size of the holding space 101 by gradually advancing the polymerization of the tip portions. That is, as the polymerization amount of the first holding piece 110 and the second holding piece 120 increases, the locking amount of the first locking portion and the second locking portion increases, or the relative locking positions of the first locking portion and the second locking portion change. FIG. 8 is a schematic cross-sectional view of the wiring and pipe material holder 100 showing a form in which the polymerization of the first holding piece 110 and the second holding piece 120 is completely advanced and the holding space 101 is reduced to the maximum extent.

[0029] In addition, the wiring and pipe material holder 100 of the present embodiment is configured to be connectable to other wiring and pipe material holders 100 (which are the same articles) in the arrangement direction intersecting the arrangement direction (see FIG. 20 and the like). That is, the wiring and pipe material holder 100 includes a connecting mechanism for connecting one wiring and pipe material holder 100 and another wiring and pipe material holder 100 adjacent to the one wiring and pipe material holder 100 in the arrangement direction intersecting the arrangement direction.

[0030] Furthermore, the wiring and pipe material holder 100 of the present embodiment includes an engagement preventing means for preventing the engagement teeth of the first locking tooth row 113 and the engagement teeth of the second locking tooth row 123 from engaging in a number of sets less than a specific number N (=3>1) with respect to the locked state of the first locking portion and the second locking portion. In the present embodiment, the second locking tooth row 123 is composed of three locking teeth, and the engagement in a number of sets of locking teeth less than three is prevented. Note that the specific number N indicating the number of sets of locking tooth sets required for an engagement of sufficient strength and the number of locking teeth of each locking tooth row can be arbitrarily designed according to the object to be held, the application, and the like.

[0031] Hereinafter, each component of the wiring and pipe material holder 100 of the present embodiment will be described in detail.

[0032] The first holding piece 110 extends from the proximal end side to the distal end side, and includes a block-shaped wall portion located from the proximal end side to the center, and an arm-shaped wall portion erected on the distal end side of the block-shaped wall portion. This arm-shaped wall portion forms the distal end portion of the first holding piece 110. Further, a thin hinge 130 is continuously provided at the proximal end of the block-shaped wall portion of the first holding piece 110. And the first holding piece 110 includes a base portion 111 as a base fixed to the structure, a first gripping portion 112 that is continuously provided to the base portion 111 and forms an arc-shaped recess on the inner surface for gripping the wiring and piping material P, and a first locking portion (first locking tooth row 113) for maintaining the surrounding of the wiring and piping material P by the holding space 101.

[0033] As shown in FIG. 5, the base portion 111 extends in the extending direction of the first holding piece 110, and has a first side portion 111a on the right side in the front view in the extending direction and a second side portion 111b on the left side in the front view. Here, the first side portion 111a and the second side portion 111b are both edges (excluding the movable portions) in the front view of the first holding piece 110. Further, a flat fixing surface 111c is defined on the bottom surface of the base portion 111. As shown in FIG. 5, a recess 111d for accommodating the head of the fixing screw 15 is provided substantially at the center in the extending direction of the base portion 111. And at the bottom of the recess 111d, an insertion portion 111e is formed that penetrates the base portion 111 vertically and through which the shaft portion of the screw 15 is inserted when fixing to the structure.

[0034] The first gripping portion 112 forms an arc-shaped recess so as to grip the wiring and pipe material P above the base portion 111 and across the extending direction from the proximal end to the distal end of the first holding piece 110. On the distal end side of the first holding piece 110, a part of the first gripping portion 112 rises with respect to the base portion 111. The first gripping portion 112 is formed as a curved surface having a substantially arc shape in a cross-sectional view on the inner surface of the recess facing the second holding piece 120. This curved surface is defined as the first arc portion. The arc shape of the first arc portion is defined to coincide with the circumference of the corresponding maximum diameter (that is, the outer peripheral shape of the wiring and pipe material PL). In other words, the curvature of the first arc portion corresponds to the circle of the corresponding maximum diameter. Further, the first arc portion has an arc plate-shaped rib 112a that enters the trough portion of the wiring and pipe material P, which is a corrugated flexible pipe, and locks the wiring and pipe material P in the longitudinal direction.

[0035] On the arcuately curved outer surface of the arm-shaped wall portion of the first holding piece 110, a first locking tooth row 113 composed of a plurality of locking teeth formed continuously in the progress direction of polymerization is formed as a first locking portion. In the present embodiment, two rows of the first locking tooth rows 113 are aligned in the circumferential direction and are provided so as to be separated from each other on both sides in the width direction of the first holding piece 110. Further, each first locking tooth row 113 extends over most of the circumferential direction of the outer surface of the arm-shaped wall portion. Each locking tooth constituting the first locking tooth row 113 has an inclined surface on the distal end side and has a sawtooth shape having a locking surface standing substantially perpendicular to the outer surface of the arm-shaped wall portion on the opposite side. And it allows movement in only one direction with respect to the sawtooth-shaped locking teeth of the second locking tooth row 123 described later and acts so as to lock in the other direction. Note that the first locking tooth row 113 has a larger number of locking teeth than the number of locking teeth (minimum locking number N) of the second locking tooth row 123. The larger the number of locking teeth constituting the first locking tooth row 113, the more possible it is to maintain the connection between the first holding piece 110 and the second holding piece 120 in a state where the holding space 101 is further reduced. In other words, the maximum polymerization amount of the first holding piece 110 and the second holding piece 120 is determined by the number of locking teeth of the one with the larger number of locking teeth among the first locking tooth row 113 and the second locking tooth row 123.

[0036] Further, a flat dividing wall 115 is provided on the curved outer surface of the arm-shaped wall portion of the first holding piece 110. The dividing wall 115 is formed on the tip side of the first holding piece 110 and extends across the entire curved outer surface at the center in the width direction of the arm-shaped wall portion. Further, the dividing wall 115 is a wall portion that rises at a right angle to the bottom surface of the first holding piece 110, and its linearly rising edge forms the second side portion 111b. And the dividing wall 115 is formed between the two rows of first locking tooth rows 113 and is arranged so as to divide the first locking tooth row 113 into two in the width direction. This dividing wall 115 functions as a regulating portion for regulating the displacement in the width direction of the second holding piece 120 described later. Further, a tapered guide edge portion 115a is formed at the tip of the dividing wall 115. The guide edge portion 115a functions to guide the entry of the dividing wall 115 into the dividing groove 125 of the second holding piece 120 described later.

[0037] As shown in FIGS. 3(a) and 6, the side surfaces on both sides of the dividing wall 115 and the two rows of first locking tooth rows 113 are separated from each other, and a concave groove portion 116 is provided therebetween. The concave groove portion 116 is a region recessed relatively to the first locking tooth row 113, and is an elongated passage extending in the circumferential direction substantially over the entire arm-shaped wall portion formed beside each first locking tooth row 113. As will be described later, the concave groove portion 116 functions as a guide passage for guiding the progress of the second holding piece 120 in the overlapping direction, or as a receiving recess for receiving the rib portion 124 of the second holding piece 120.

[0038] Also, as shown in FIGS. 3(a) and 6, the circumferential tip portions of each concave groove portion 116 (the end portions facing the tip portion of the second holding piece 120) are closed by the blocking wall portion 114. The blocking wall portion 114 is a wall portion formed beside the most distal locking tooth of the first locking tooth row 113. Each blocking wall portion 114 is integrally formed between each side surface of the dividing wall 115 and the locking tooth and has the same cross-sectional shape as the locking tooth. The blocking wall portion 114 is a part of the engagement blocking means for blocking the engagement of the locking teeth of the first locking tooth row 113 and the locking teeth of the second locking tooth row 123 with a number of sets less than a specific number N (= 3).

[0039] As shown in Fig. 7, an engaging portion 118 and an engaged portion 119 as a connecting mechanism are respectively provided on the first side portion 111a and the second side portion 111b of the base portion 111 of the first holding piece 110. In the present embodiment, the engaging portion 118 and the engaged portion 119 are provided near the bottom of the first holding piece 110.

[0040] The engaging portion 118 is formed to protrude from the first side portion 111a in the arrangement direction of the wiring / wiring pipe holder 100. The engaging portion 118 includes a base end 118a integrally connected to the outer wall (the first side portion 111a) of the first holding piece 110, and a main body portion 118b that extends from the base end 118a toward the bottom side and bulges outward in the arrangement direction and has a semi-circular shape in front view. An engaging groove 118c having a T-shape in plan view and penetrating vertically and opening outward is formed in the main body portion 118b. A cavity in which the main body portion 118b can retract is formed inside the engaging portion 118 of the first holding piece 110 in the arrangement direction. The engaging portion 118 can be displaced in and out in the arrangement direction by rotation around the base end 118a, and can be displaced so as to change the protruding amount in the arrangement direction.

[0041] On the other hand, the engaged portion 119 is formed on the second side portion 111b in the arrangement direction of the wiring / wiring pipe holder 100 so as to be engageable with the engaging portion 118. The engaged portion 119 is provided at the edge of the partition wall 115 in the arrangement direction and is formed to project in the width direction from both side surfaces of the partition wall 115. That is, the engaged portion 119 is composed of a connecting piece having a T-shape that can be fitted into the T-shaped engaging groove 118c in cooperation with the partition wall 115. Further, the engaged portion (connecting piece) 119 is arranged so as to be separated from the first locking tooth row 113 with the partition wall 115 interposed therebetween. Thereby, when the locking operation is performed, the tip portion of the second holding piece 120 is prevented from interfering with the engaged portion 119.

[0042] The engaging portion 118 and the engaged portion 119 are configured to be engageable and disengageable with each other by relatively sliding in the standing direction (direction perpendicular to the bottom surface) (see FIG. 24). Then, by the engagement of the engaging portion 118 of one wiring / wiring and pipe material holder 100 and the engaged portion 119 of the other wiring / wiring and pipe material holder 100, the wiring / wiring and pipe material holders 100, 100 adjacent in the arrangement direction are connected (see FIG. 23). As shown in FIGS. 5 and 13, if necessary, the engaging portion 118 can be displaced from a first position where it can be connected to the engaged portion 119 of the other wiring / wiring and pipe material holder 100 to a second position where it does not protrude more than the outer surface (first side portion 111a) of the base portion 111 where it cannot be connected to the engaged portion 119 of the other wiring / wiring and pipe material holder 100.

[0043] The second holding piece 120 is formed of a band-shaped body extending in an arc shape from the base end side to the tip end side. The second holding piece 120 has a base end portion curved in an arc shape and a tip end portion continuously provided to the base end portion and curved more gently. A thin hinge 130 is continuously provided at the base end portion of the second holding piece 120. The curved shape of the tip end portion of the second holding piece 120 corresponds to the curved shape of the outer surface of the arm-shaped wall portion of the first holding piece 110 in order to overlap the tip end portion of the first holding piece 110.

[0044] At the tip end portion of the second holding piece 120, separation pieces 121 separated in the width direction within a range of a predetermined length from the circumferential tip end are provided. The two separation pieces 121 have free ends independent of each other. One separation piece and the other separation piece of the two separation pieces 121 can be elastically bent and deformed radially inward and outward around their base ends independently of each other. Further, the two separation pieces 121 are formed side by side in the width direction orthogonal to the extending direction of the second holding piece 120 and are divided in the width direction with a split groove 125 of a predetermined width therebetween. This split groove 125 has a width through which the split wall 115 of the first holding piece 110 can be inserted.

[0045] The second holding piece 120 includes a second gripping portion 122 that forms an arc-shaped recess on the inner surface for gripping the wiring / wiring and pipe material P, and a second locking portion (second locking tooth row 123) for maintaining the surrounding of the wiring / wiring and pipe material P by the holding space 101.

[0046] The second gripping portion 122 forms an arcuate recess so as to grip the wiring and pipe material P along the extending direction from the proximal end to the distal end of the second holding piece 120. The second gripping portion 122 is formed as a curved surface that is substantially arcuate in cross-sectional view on the inner surface of the recess facing the first holding piece 110. This curved surface is defined as the second arc portion. The arc shape of the second arc portion is defined to coincide with the circumference of the corresponding maximum diameter (that is, the outer peripheral shape of the wiring and pipe material PL). In other words, the curvature of the second arc portion corresponds to the circle of the corresponding maximum diameter. Further, the second arc portion has an arcuate plate-shaped rib 122a that enters the trough portion of the wiring and pipe material P, which is a corrugated flexible tube, and locks the wiring and pipe material P in the longitudinal direction.

[0047] On the inner surface of the tip portion of the second holding piece 120, as the second locking portion, a second locking tooth row 123 composed of a plurality (here, three) of locking teeth formed continuously in the progress direction of polymerization is formed. The second locking portion is provided on each of the two separation pieces 121. That is, two rows of the second locking tooth rows 123 are aligned in the circumferential direction and are provided spaced apart from each other on both sides in the width direction of the second holding piece 120. These two rows of the second locking tooth rows 123 are respectively arranged at width direction positions where they can face the two rows of the first locking tooth rows 113 in the radial direction. Further, each second locking tooth row 123 is formed at the tip of each separation piece 121 and is composed of three locking teeth. Each locking tooth constituting the second locking tooth row 123 has an inclined surface on the tip side and a locking surface standing substantially perpendicular to the inner surface of the separation piece 121 on the opposite side, forming a sawtooth shape. When the tip portions of the first holding piece 110 and the second holding piece 120 are polymerized, the locking teeth of the first locking tooth row 113 and the second locking tooth row 123 are engaged with each other in a catching manner in the radial direction. At this time, by the sliding contact of the inclined surfaces of the locking teeth with each other, relative movement in the direction of reducing the holding space 101 by advancing the polymerization is allowed. When advancing the polymerization, when one locking tooth overrides the opposing other locking tooth by the sliding of the inclined surfaces and then meshes with the next locking tooth, the user can feel the catching tactile sensation and sound due to the meshing of the locking teeth. On the other hand, when the locking surfaces of the locking teeth are locked to each other, relative movement in the direction of expanding the holding space 101 by retreating the polymerization is restricted. Further, when the second locking tooth row 123 is displaced relatively radially outward with respect to the first locking tooth row 113, the locking state by both locking teeth is released.

[0048] Also, as shown in FIGS. 1(b), 4, and 6, a blocking projection (a part of the engagement blocking means) or a rib portion 124 as a guiding projection is formed on the side inside the width direction of the second locking tooth row 123. The rib portion 124 extends along the arrangement from the first locking tooth to the third locking tooth on the tip side of the second locking tooth row 123. That is, the rib portion 124 has a length extending over all the locking teeth of the second locking tooth row 123. The rib portion 124 projects from the inner surface of the edge inside the width direction of each separation piece 121 and is integrally formed on the side portions inside the width direction of three (specific number N) locking teeth. The rib portion 124 functions as a blocking projection that cooperates with the blocking wall portion 114 as a part of the engagement blocking means to prevent the locking teeth of the first locking tooth row 113 and the locking teeth of the second locking tooth row 123 that face each other in the radial direction from engaging in a number of sets less than the specific number N (= 3). Note that the form of the rib portion 124 can be changed as needed. For example, when the specific number N is 2, the rib portion 124 can be formed to extend along the arrangement from the first locking tooth to the second locking tooth on the tip side of the second locking tooth row 123. Alternatively, when the specific number N is greater than 3, the rib portion 124 can be formed to extend along the arrangement from the first locking tooth to the N-th (> 3) locking tooth on the tip side of the second locking tooth row 123. Also, the number of teeth constituting the second locking tooth row 123 may be more than the specific number N.

[0049] Each rib portion 124 is formed at the same position in the width direction as each blocking wall portion 114 provided at the tip of the first holding piece 110. And the rib portion 124 is configured to abut against the blocking wall portion 114 from the radial direction when the tip portions of the first holding piece 110 and the second holding piece 120 start to overlap. The leading edge of the rib portion 124 is chamfered in a tapered shape so that when it abuts against the leading edge of the blocking wall portion 114, the second holding piece 120 is guided to the outside in the radial direction of the first holding piece 110. Further, the rib portion 124 preferably has a protruding height greater than or equal to the protruding height of the locking teeth in order to prevent the locking teeth from catching on each other. Here, the protruding height of the rib portion 124 and the protruding height of the locking teeth are substantially the same. Also, the rib portion 124 is configured to be received in a recessed rib portion 116 formed beside the blocking wall portion 114 on the advancing direction side (or at a position beyond the blocking wall portion 114 on the advancing direction side) of the first locking tooth row 113 of the first holding piece 110. Thereby, when the overlapping of the first holding piece 110 and the second holding piece 120 advances to a position where the blocking wall portion 114 and the rib portion 124 do not overlap, the recessed rib portion 116 is received in the rib portion 124 as a receiving recess, and the engagement between the locking teeth of the first locking tooth row 113 and the locking teeth of the second locking tooth row 123 is allowed. Note that a series of operations by the engagement preventing means will be described in more detail later with reference to FIG. 17. Further, the rib portion 124 is slidable as a guiding convex portion guided by the recessed rib portion 116 which is a guiding passage. By maintaining the rib portion 124 within the recessed rib portion 116, in the operation of advancing the overlapping, the displacement of each separating piece 121 in the width direction is prevented.

[0050] In addition, each of the separation pieces 121 of the second holding piece 120 is provided with a release operation portion 128 that protrudes outward in the width direction at its tip. That is, the release operation portions 128 protrude on both sides in the arrangement direction of the second holding piece 120. The release operation portion 128 is operated by a user to lift it outward (radially) of the holding space 101 with a finger or a shaft-like operation tool T (see FIGS. 18 and 19), etc., so that the second locking portion is separated from the first locking portion in the radial direction of the wiring and pipe material P, and the locking of the first locking portion and the second locking portion is configured to be released. In the present embodiment, the release operation portion 128 is a rectangular knob, but its shape can be arbitrarily selected. Further, the release operation portion 128 protrudes along the arrangement direction so as to face the outer peripheral surface of the wiring and pipe material P to be held with a gap therebetween. The gap is formed to have a size that allows the operation tool T to be inserted between the outer peripheral surface of the wiring and pipe material P held in the holding space 101 and the release operation portion 128 (see FIG. 19(a)). Further, since the two separation pieces 121 are independently elastically deformable from each other, by operating one of the release operation portions 128, only one of the separation pieces 121 is operated to be unlocked.

[0051] The hinge 130 connects the proximal ends of the first holding piece 110 and the second holding piece 120, and is configured to rotate the first holding piece 110 in the opening and closing directions of the second holding piece 120. The hinge 130 is a thin piece that forms a relatively thin portion with respect to the first holding piece 110 and the second holding piece 120, and is elastically deformable preferentially with respect to other portions. When the first holding piece 110 and the second holding piece 120 are displaced in the direction in which they overlap, the hinge 130 bends and deforms into an acute angle. On the other hand, when the first holding piece 110 and the second holding piece 120 are displaced in the direction of expanding the opening portion 103, the hinge 130 bends and deforms into an obtuse angle. Due to the bending of the hinge 130, a hinge-side space 105 is formed inside thereof.

[0052] The auxiliary piece 140 is provided to prevent the wiring and piping material P held in the holding space 101 from escaping into the hinge-side space 105. The auxiliary piece 140 is an arcuate strip that rises with a protruding length from the inner surface of the first holding piece 110 with its tip as a free end toward the inner surface of the second holding piece 120. The auxiliary piece 140 is arranged to be positioned between the wiring and piping material P disposed in the holding space 101 and the hinge 130. In particular, the auxiliary piece 140 is connected to the base end of the first arc portion and is arranged offset toward the hinge 130 side from the center of the holding space 101 of the first holding piece 110. In the present embodiment, the auxiliary piece 140 rises within the holding space 101 when holding the wiring and piping material PS of the corresponding minimum diameter. Further, the auxiliary piece 140 is erected so as to face the inner surface of the tip portion of the first holding piece 110. And, on the hinge 130 side of the auxiliary piece 140, a space is formed that allows the auxiliary piece 140 to tilt toward the hinge 130 side. The space is a retraction space for the inner surface (the side that contacts the wiring and piping material P) of the auxiliary piece 140 to retract to a position continuous with the inner surface of the second holding piece 120. Furthermore, the distance between the tip of the auxiliary piece 140 and the tip of the first holding piece 110 is smaller than the diameter of the wiring and piping material PL of the maximum diameter.

[0053] The auxiliary piece 140 includes a base end portion 141 that is elastically bendable and deformable on its base end side, and a contact portion 142 that can contact the outer peripheral surface of the wiring and piping material P. The base end portion 141 is a relatively thin portion of the auxiliary piece 140 and assists the elastic tilting of the auxiliary piece 140. Also, the contact portion 142 has an arcuate curved surface facing the tip side of the first holding piece 110 for contacting the outer peripheral surface of the wiring and piping material P. The curved surface of the contact portion 142 is defined to coincide with the circumference of the corresponding maximum diameter (that is, the outer peripheral shape of the wiring and piping material PL). In other words, the curvature of the curved surface of the contact portion 142 corresponds to a circle of the corresponding maximum diameter. Further, the contact portion 142 has an arcuate plate-shaped rib 142a that enters the groove portion of the wiring and piping material P, which is a corrugated flexible tube, and locks in the longitudinal direction. That is, the first arc portion, the second arc portion, and the curved surface of the contact portion 142 have the same curvature and are configured to be able to be positioned on the same circumference of the diameter of the wiring and piping material PL.

[0054] Also, when gripping a wiring or pipe material P with a predetermined diameter (including the wiring or pipe material PS with the minimum corresponding diameter), the auxiliary piece 140 is disposed on the tip side of the first holding piece 110 relative to the holding position of the wiring or pipe material P so as to abut against the outer peripheral surface of the wiring or pipe material P and tilt toward the hinge 130 side. As shown by the phantom line in FIG. 4, the contact portion 142 is elastically displaceable so as to tilt toward the hinge 130 side about the base end portion 141 from the initial position. And when disposing the wiring or pipe material P with a size from the corresponding minimum diameter to the maximum diameter in the holding space 101, along with the clamping of the wiring or pipe material P, the auxiliary piece 140 elastically tilts toward the hinge 130 side, and by its elastic force, presses against the wiring or pipe material P. On the other hand, when introducing the wiring or pipe material PL with the maximum corresponding diameter into the holding space 101, the auxiliary piece 140 can also act to temporarily hold the wiring or pipe material PL by sandwiching the wiring or pipe material PL in cooperation with the inner surface of the tip portion of the first holding piece 110 facing the inner surface of the contact portion 142 thereof.

[0055] Furthermore, the auxiliary piece 140 is configured such that when reducing the holding space 101 in which the wiring or pipe material P is disposed, the tip of the auxiliary piece 140 abuts against the inner surface of the second holding piece 120. For example, when holding the wiring or pipe material PS with the minimum corresponding diameter, as shown by the phantom line in FIG. 8, the auxiliary piece 140 is pressed toward the hinge 130 side by the wiring or pipe material PS, so that it retreats toward the hinge 130 side and assumes a standing-up posture. When the auxiliary piece 140 is in the retracted position (the phantom line in FIG. 8), since it interferes with the inner surface of the second holding piece 120, it will be pressed from the hinge 130 side to the tip side of the second holding piece 120 by the inner surface of the second holding piece 120. By this pressing force, the auxiliary piece 140 can also operate so as to be moved along to the tip side of the second holding piece 120 from the retracted position. Thus, with the wiring or pipe material P with a predetermined diameter held in the holding space 101, the position and protruding length of the auxiliary piece 140 are determined such that the tip of the auxiliary piece 140 tilted to the retracted position according to the diameter of the wiring or pipe material P abuts or presses against the inner surface of the second holding piece 120 (or the inner surface of the second arc portion).

[0056] Next, with reference to FIGS. 9 to 12, an installation structure 10 in which a wiring and pipe material holder 100 of the present embodiment holds and arranges a wiring and pipe material PS having a corresponding minimum diameter with respect to a construction material 11 (structure) will be described. FIG. 9 is a schematic perspective view of the installation structure 10. FIG. 10 is a schematic front view of the installation structure 10. FIG. 11 is a cross-sectional view taken along line E-E of the installation structure 10. FIG. 12 is a cross-sectional view taken along line F-F of the installation structure 10.

[0057] As shown in FIGS. 9 and 10, in the installation structure 10 of the present embodiment, the structure is a columnar construction material 11 standing vertically, and a wiring and pipe material holder 100 is fixed to the side surface (installation surface) on the front side of the construction material 11. Then, the wiring and pipe material PS is gripped by the wiring and pipe material holder 100, and its laying direction is arranged along the vertical direction.

[0058] As shown in FIG. 12, in the installation structure 10, after the fixing surface 111c of the base portion 111 of the wiring and pipe material holder 100 abuts against the side surface of the construction material 11, the screw 15 passes through the insertion portion 111e, whereby the wiring and pipe material holder 100 is fixed to the construction material 11. At this time, the head of the screw 15 is accommodated in the recess 111d of the base portion 111, and the shaft portion is screwed into the construction material 11. The wiring and pipe material holder 100 is fixed in a posture in which its width direction is along the vertical direction.

[0059] In the installation structure 10, the wiring and pipe material PS is held in the closed holding space 101 of the wiring and pipe material holder 100. As shown in FIG. 11, the tip portions of the first holding piece 110 and the second holding piece 120 overlap each other, and the second locking tooth row 123 meshes with the first locking tooth row 113 from the radially outer side, thereby maintaining the closed state of the holding space 101. In the installation structure 10 for holding the wiring and pipe material PS having the corresponding minimum diameter, three locking teeth of the second locking tooth row 123 are engaged with the three locking teeth on the rearmost side of the first locking tooth row 113 so that the overlapping amount of the first holding piece 110 and the second holding piece 120 is maximized. By circumferentially locking the locking surfaces of the first locking tooth row 113 and the second locking tooth row 123, relative movement of the second holding piece 120 relative to the first holding piece 110 in the direction in which the overlap retreats is restricted. As a result, the state in which the holding space 101 surrounding the wiring and pipe material PS is minimized is maintained.

[0060] In the installation structure 10, as shown in FIG. 11, the arc portion of the first gripping portion 112, the arc portion of the second gripping portion 122, and the contact portion 142 of the auxiliary piece 140 are each pressed against the outer peripheral surface (crest outer peripheral surface) of the wiring and pipe material PS, whereby the wiring and pipe material PS is gripped. Also, as shown in FIG. 12, the ribs 112a, 122a, 132a enter the troughs of the wiring and pipe material PS and are pressed against the outer peripheral surfaces of the troughs. As a result, the wiring and pipe material PS is stably gripped so as not to float within the holding space 101.

[0061] Further, the auxiliary piece 140 is positioned between the outer peripheral surface of the wiring and pipe material PS and the hinge 130. The auxiliary piece 140 blocks the communication between the holding space 101 and the hinge-side space 105. Further, the tip of the auxiliary piece 140 is engaged with the inner surface of the second gripping portion 122 of the second holding piece 120 in a posture where it has retreated from the original position toward the hinge 130 side. The auxiliary piece 140 is pressed from the hinge 130 side toward the center of the holding space 101 (the tip side of the first holding piece 110 or the second holding piece 120) by the inner surface of the second gripping portion 122. Due to this pressing force, the gripping of the wiring and pipe material PS by the three points of the first holding piece 110, the second holding piece 120, and the auxiliary piece 140 becomes stronger. And since the auxiliary piece 140 supports the wiring and pipe material PS from the hinge 130 side, it does not tilt further into the hinge-side space 105. Therefore, the auxiliary piece 140 prevents the wiring and pipe material PS from escaping from the holding space 101 to the hinge-side space 105. Further, the auxiliary piece 140 is stretched and disposed between the inner surface of the first holding piece 110 and the inner surface of the second holding piece 120. As a result, the fulcrum of the rotation of the second holding piece 120 with respect to the first holding piece 110 moves from the hinge 130 to the tip of the auxiliary piece 140, and the smooth rotation in the direction of retreating the overlapping of the first holding piece 110 and the second holding piece 120 centered on the hinge 130 is hindered. As a result, it is possible to more firmly maintain the locked state between the first locking portion and the second locking portion.

[0062] In addition, the locked state of the wiring and pipe material holder 100 is formed by the independent engagement of the second locking tooth row 123 formed on the two separating pieces 121 of the second holding piece 120 and the two rows of the first locking tooth rows 113. That is, even if one separating piece 121 is accidentally displaced radially outward and the engagement of one set of the first locking tooth row 113 and the second locking tooth row 123 is released, the engagement of the other set can be maintained. Further, in the installation structure 10, the partition wall 115 of the first holding piece 110 enters the partition groove 125 of the second holding piece 120, and the rib portion 124 formed beside the second locking tooth row 123 is housed in the groove portion 116, thereby restricting the displacement of the first holding piece 110 and the second holding piece 120 in the laying direction (width direction) of the wiring and pipe material PS. That is, in the installation structure 10, the gripping of the wiring and pipe material PS by the wiring and pipe material holder 100 is firmly maintained.

[0063] FIG. 13 shows an alternative installation structure 10-1 in which a wall material 13 is further erected on the side surface of the construction material 11 with respect to the installation structure 10 shown in FIG. 12. In the installation structure 10 shown in FIG. 12, the outer surface of the first side portion 111a of the wiring and pipe material holder 100 is located on the outer edge of the side surface (installation surface) of the construction material 11, and the engaging portion 118 protrudes from the side surface (installation surface). On the contrary, in the installation structure 10-1 shown in FIG. 13, due to the erection of the wall material 13, the wall surface of the wall material 13 and the engaging portion 118 are in contact, and the engaging portion 118 is displaced inward of the first side portion 111a. That is, the engaging portion 118 is displaced from the first position (see FIG. 12) where it can be connected to the engaged portion 119 of another wiring and pipe material holder 100 to the second position (see FIG. 13) that does not protrude beyond the outer surface of the first side portion 111a of the base portion 111. Therefore, in the installation structure 10-1, the wall material 13 is erected on the side surface of the construction material 11 without interfering with the wiring and pipe material holder 100.

[0064] FIG. 14 shows an installation structure 10-2 of another form in which the wiring and pipe material PL having the largest diameter among the corresponding wiring and pipe materials P is arranged with respect to the installation structure 10 of FIG. 11. In the installation structure 10-2, the wiring and pipe material PL is held in the closed holding space 101 of the wiring and pipe material holder 100. The tip portions of the first holding piece 110 and the second holding piece 120 overlap each other, and the second locking tooth row 123 meshes with the first locking tooth row 113 from the radially outer side, so that the closed state of the holding space 101 is maintained. In the installation structure 10 for holding the wiring and pipe material PL having the corresponding maximum diameter, three locking teeth of the second locking tooth row 123 are engaged with the three locking teeth on the most distal side of the first locking tooth row 113 so that the overlapping amount of the first holding piece 110 and the second holding piece 120 is minimized. By locking the locking surfaces of the first locking tooth row 113 and the second locking tooth row 123 in the circumferential direction, the second holding piece 120 is restricted from relatively moving in the direction in which the overlap retreats with respect to the first holding piece 110. As a result, the holding space 101 surrounding the wiring and pipe material PL is maintained in a state where it is maximized.

[0065] Then, as shown in FIG. 14, the arc portion of the first gripping portion 112, the arc portion of the second gripping portion 122, and the contact portion 142 of the auxiliary piece 140 are in contact with the outer peripheral surface (crest outer peripheral surface) of the wiring and pipe material PL, respectively, so that the wiring and pipe material PL is gripped. At this time, the first arc portion, the second arc portion, and the curved surface of the contact portion 142 are located on the same circumference substantially coinciding with the outer peripheral surface of the wiring and pipe material PL (of the crest). Although not shown, the ribs 112a, 122a, 132a enter the trough portion of the wiring and pipe material PL and are in contact with the outer peripheral surface of the trough portion. Similarly, the inner peripheral edges of the ribs 112a, 122a, 132a are located on the same circumference substantially coinciding with the outer peripheral surface of the wiring and pipe material PL (of the trough). Therefore, the wiring and pipe material PL is stably gripped by the wiring and pipe material holder 100 so as not to float in the holding space 101. When holding the wiring and pipe material PL having the corresponding maximum diameter, the holding position of the wiring and pipe material PL is determined at one location in the holding space 101, and there is no need to check the position of the wiring and pipe material PL or align the wiring and pipe material PL.

[0066] Further, the auxiliary piece 140 is located between the outer peripheral surface of the wiring and pipe material PL and the hinge 130. The auxiliary piece 140 is tilted to a position close to the hinge 130. And the auxiliary piece 140 blocks the communication between the holding space 101 and the hinge-side space 105. Further, the tip of the auxiliary piece 140 is in contact with the inner surface near the base end of the second holding piece 120 in a posture of retreating from the original position toward the hinge 130 side. At this time, the second holding piece 120 does not urge the auxiliary piece 140 toward the center of the holding space 101. That is, when holding the wiring and pipe material PL with the maximum diameter, the auxiliary piece 140 retreats to a position where it is not pressed (or moved along) to the tip side by the inner surface of the second holding piece 120.

[0067] Subsequently, with reference to FIG. 15, a method of constructing an installation structure 10 in which a wiring and pipe material PS (with the corresponding minimum diameter) is disposed with respect to the construction material 11 using the wiring and pipe material holder 100 will be described.

[0068] As shown in FIG. 15, the wiring and pipe material holder 100 is fixed to a predetermined fixed position on the installation surface of the construction material 11. While aligning the fixing surface 111c of the wiring and pipe material holder 100 with the installation surface of the construction material 11, the position of the wiring and pipe material holder 100 is determined, and its posture is maintained so as to define the laying direction of the wiring and pipe material P, and the screw 15 is inserted into the insertion portion 111e from the front. Then, by operating a tool (driver) to screw the screw 15 into the construction material 11, the wiring and pipe material holder 100 can be fixed to the construction material 11.

[0069] Next, with reference to FIG. 16, each step of a method of gripping the wiring and pipe material P with the wiring and pipe material holder 100 will be illustrated.

[0070] First, open the opening portion 103 of the wiring and pipe material holder 100, and insert the wiring and pipe material P into the holding space 101 through the opening portion 103. As shown in Fig. 16(a), place the wiring and pipe material P between the tip portion of the first holding piece 110 and the auxiliary piece 140. At this time, the wiring and pipe material P is located on the tip side of the center of the holding space 101 and is sandwiched between the contact portion 142 of the auxiliary piece 140 elastically displaced radially outward and the inner surface of the first holding piece 110. Then, rotate the second holding piece 120 about the hinge 130 in the direction of closing the opening portion 103. Superimpose the tip portion of the first holding piece 110 and the tip portion of the second holding piece 120, and engage the first locking tooth row 113 and the second locking tooth row 123. Here, by the engagement preventing means, it is prevented that two or less locking teeth of the second locking tooth row 123 engage with the locking teeth of the first locking tooth row 113. After the superposition proceeds to the position where three sets of locking teeth face each other, the locking state by the first locking portion and the second locking portion is first formed (see Fig. 17).

[0071] After the locking state is first formed, when the superposition of the first holding piece 110 and the second holding piece 120 is continued, as shown in Fig. 16(b), the inner surface of the second holding piece 120 abuts against the outer peripheral surface of the wiring and pipe material P. Then, when the tightening operation is continued to reduce the holding space 101, as shown in Fig. 16(c), the wiring and pipe material P is pushed toward the center of the holding space 101, the auxiliary piece 140 tilts toward the hinge 130 side and rises from the inclined posture, and the tip of the auxiliary piece 140 abuts (or approaches) the inner surface of the second holding piece 120.

[0072] Furthermore, when operating to strongly tighten the second holding piece 120 against the first holding piece 110, as shown in FIG. 16(d), while the tip of the auxiliary piece 140 is in pressure contact with the inner surface of the second holding piece 120, the auxiliary piece 140 is moved toward the center side of the holding space 101 and slightly tilted. In other words, along with the operation of reducing the holding space 101, the tip of the auxiliary piece 140 slides on the inner surface of the second holding piece 120, and the auxiliary piece 140 tilts toward the tip side of the second holding piece 120. Then, the auxiliary piece 140 acts to bias or press the wiring and pipe material P toward the center side of the holding space 101. In this way, the pressing force of the auxiliary piece 140 increases due to the step-by-step engagement of the first locking portion and the second locking portion in the direction of reducing the size of the holding space 101. As a result, it is possible to firmly grip the wiring and pipe material P by the wiring and pipe material holder 100 and stably hold it in the holding space 101.

[0073] When wiring and pipe materials P with different diameters are arranged, although the engagement positions of the first locking tooth row 113 and the second locking tooth row 123 shift to the tip side or the rear end side, the basic process is the same. However, the operation of the auxiliary piece 140 changes according to the diameter of the wiring and pipe material P. For example, when holding the wiring and pipe material PL with the maximum corresponding diameter, since the auxiliary piece 140 completely retracts to the hinge 130 side, it is not pressed to the tip side against the inner surface of the second holding piece 120 and is not moved toward the center side of the holding space 101.

[0074] Next, with reference to FIG. 17, the action of the engagement preventing means in the above-described process will be described. By the engagement preventing means, it is prevented that less than a specific number N of the locking teeth in the second locking tooth row 123 engage with the locking teeth in the first locking tooth row 113. The specific number N can be selected from integers of 2 or more. In the present embodiment, the specific number N is 3, which is the number of teeth in the second locking tooth row 123. That is, it is prevented that engagement by only one or two sets of locking teeth is formed.

[0075] As shown in Fig. 17(a), when the polymerization of the tip portions of the first holding piece 110 and the second holding piece 120 starts, the rib portion 124 of the second holding piece 120 abuts against and rides on the outer surface of the blocking wall portion 114 of the first holding piece 110. At this time, the second holding piece 120 is in a state of being elastically deformed radially outward. As shown in Fig. 17(b), as the polymerization progresses, the rib portion 124 slides on the blocking wall portion 114. At this time, since the blocking wall portion 114 and the rib portion 124 are in contact with each other in the radial direction, the engagement of the opposing locking teeth of the first locking tooth row 113 and the second locking tooth row 123 is prevented. This prevention of engagement continues until the position where the blocking wall portion 114 and the rib portion 124 overlap, that is, the position where two sets (<N = 3) of locking teeth face each other.

[0076] Furthermore, when the polymerization amount increases and reaches the position where the number of opposing locking teeth becomes 3, the rib portion 124 gets over the blocking wall portion 114. Then, the rib portion 124 is received in the groove portion 116 as a receiving recess at the position where the blocking wall portion 114 and the rib portion 124 do not overlap. As shown in Fig. 17(c), while the tip portion of the second holding piece 120 is elastically displaced radially inward, the three locking teeth of the second locking tooth row 123 simultaneously engage with the three locking teeth on the tip side of the first locking tooth row 113. In this way, by the locking prevention means, it is possible to form at once a locking state having sufficient locking strength (that is, the engagement of a specific number N sets of locking teeth) between the first locking portion and the second locking portion without forming an insufficient locking state halfway. And after the first locking state is formed, as shown in Fig. 17(d), it is possible to proceed with the polymerization while maintaining the locking state of the first locking tooth row 113 and the second locking tooth row 123. That is, the wiring and pipe material holder 100 of the present embodiment can prevent the user from completing the operation in an insufficient locking state by the engagement prevention means.

[0077] Subsequently, with reference to Figs. 18 and 19, a method for releasing the locking state between the first locking portion and the second locking portion in the wiring and pipe material holder 100 that grips the wiring and pipe material P will be described.

[0078] As shown in Fig. 18, the user operates an operating tool T having a thin tip shaft such as a minus driver, and elastically displaces the second holding piece 120 radially outward of the wiring and pipe material P through the release operation portion 128 of the wiring and pipe material holder 100, thereby releasing the locked state between the first locking tooth row 113 and the second locking tooth row 123. The operation of the operating tool T is performed in a direction orthogonal to the laying direction of the wiring and pipe material P and from the space on the front side of the installation surface of the building material 11. That is, the user can operate the operating tool T using the wider space on the front side of the wiring and pipe material P to more easily release the locking. In particular, since the release operation portion 128 projects in the laying direction on the side portion of the wiring and pipe material P and forms a gap that opens in a direction different from the pipe axis (direction) of the wiring and pipe material P, it is not necessary to perform the release operation with the operating tool T (such as the handle of the operating tool being likely to interfere with the outer peripheral surface of the wiring and pipe material) along the pipe axis. Further, as shown in Fig. 18, since two separation pieces 121 are provided at the tip portion of the second holding piece 120, for each release operation, one of the separation pieces 121 is displaced and only one of the locked states is released. At this time, since the other locked state remains maintained, it is necessary to sequentially perform the release operation for the remaining separation piece 121 as well.

[0079] Referring to FIG. 19, the release operation will be described in more detail. First, insert the tip of the operating tool T into the gap between the outer peripheral surface of the wiring and pipe material P and the release operation portion 128 extending opposite thereto. Next, as shown in FIG. 19(a), bring the operating tool T into contact with two points, namely, the outer peripheral surface of the wiring and pipe material P and the release operation portion 128. With the contact point with the outer peripheral surface of the wiring and pipe material P as the fulcrum and the contact point with the release operation portion 128 as the point of application, tilt the operating tool T in the circumferential direction of the wiring and pipe material P (refer to the arrow in FIG. 19(a)). Then, as shown in FIG. 19(b), lift the release operation portion 128 radially outward of the wiring and pipe material P at the tip of the operating tool T, and the second locking tooth row 123 can be separated radially outward from the first locking tooth row 113. In this way, the locked state by the locking teeth of the first locking tooth row 113 and the second locking tooth row 123 is released. In this state, by pulling out the operating tool T from the gap, the locking release operation for one of the separation pieces 121 is completed.

[0080] Next, referring to FIGS. 20 to 23, another form of installation structure 10-3 will be described in which one wiring and pipe material holder 100 is installed on a structure in a state of being connected to another adjacent wiring and pipe material holder 100 via a connection mechanism. The installation structure 10-3 is formed by arranging a plurality of wiring and pipe material holders 100 side by side to align and arrange a plurality of wirings and pipe materials P. FIG. 20 is a schematic perspective view of the installation structure 10-3. FIG. 21 is a front view of the installation structure 10-3. FIG. 22 is a cross-sectional view taken along line G-G of the installation structure 10-3. FIG. 23 is a schematic cross-sectional view showing the connection mechanism of adjacent wiring and pipe material holders 100.

[0081] As shown in FIGS. 20 to 22, in the installation structure 10-3, a plurality of wiring and pipe material holders 100 are fixed side by side on the installation surface of the structure 11, and hold the wiring and pipe material P along a common laying direction. One wiring and pipe material holder 100 and another wiring and pipe material holder 100 are connected by a connecting mechanism in an arrangement direction intersecting the laying direction of the wiring and pipe material P. Further, a wall member 13 is erected adjacent to the wiring and pipe material holder 100 located at the outermost end. Here, the engaging portion 118 of the wiring and pipe material holder 100 rotates inside the first side portion 111a, so that the wiring and pipe material holder 100 and the wall member 13 are adjacently arranged.

[0082] As shown in FIGS. 23(a) and (b), a connected state is formed by fitting the engaged portion 119 of another adjacent wiring and pipe material holder 100 into the engaging groove 118c of the engaging portion 118 of one wiring and pipe material holder 100. In this connected state, the displacement of the engaging portion 118 of one wiring and pipe material holder 100 is restricted by engagement with the engaged portion 119 of another wiring and pipe material holder 100. In particular, since the engaging groove 118c and the engaged portion 119 extend vertically with a predetermined length with respect to the fixing surface 111c (or the installation surface of the structure), even if another wiring and pipe material holder 100 approaches or separates from one wiring and pipe material holder 100 along the fixing surface 111c, the main body portion 118b of the engaging portion 118 cannot rotate about the base end 118a. Therefore, in a state where one wiring and pipe material holder 100 and another wiring and pipe material holder 100 are applied to the installation surface of the structure, the displacement of the engaging portion 118 is restricted (regardless of whether or not it is fixed by the screw 15). That is, even before the wiring and pipe material holder 100 is fixed to the structure, it becomes easy to maintain the relative position between one wiring and pipe material holder 100 and another wiring and pipe material holder 100, and it becomes possible to perform a fixing operation on the structure in a state where one wiring and pipe material holder 100 and another wiring and pipe material holder 100 are combined.

[0083] As shown in FIG. 24, the step of connecting one wiring and pipe material holder 100 and another wiring and pipe material holder 100 in the alignment direction is performed by bringing the engaged portion 119 of the other wiring and pipe material holder 100 close to the engaging portion 118 of one wiring and pipe material holder 100 by relative sliding along a direction different from the alignment direction (here, the direction perpendicular to the fixed surface 111c). Specifically, the engaging portion 118 and the engaged portion 119 can be engaged by inserting the engaged portion 119 into the opening of the engaging groove 118c of the engaging portion 118 facing the side opposite to the fixed surface 111c (upper side in FIG. 24). Although not shown, conversely, the engaging portion 118 and the engaged portion 119 can also be engaged by inserting from the engaged portion 119 into the opening of the engaging groove 118c of the engaging portion 118 facing the fixed surface 111c side (lower side in FIG. 24). That is, since the sliding direction of the wiring and pipe material holders 100 to be connected is different from the alignment direction, it is possible to suppress the engaging portion 118 from unexpectedly displacing in the alignment direction and retracting inward during the connection operation, enabling a smooth connection operation.

[0084] Hereinafter, the effects of the wiring and pipe material holder 100 according to an embodiment of the present invention will be described.

[0085] First, according to the wiring and pipe material holder 100 of the present embodiment, an annular holding space 101 for surrounding the wiring and pipe material P is formed by the tip portions of the first holding piece 110 and the second holding piece 120 overlapping each other. In particular, by displacing the second holding piece 120 so as to overlap the first holding piece 110 from the outside of the holding space 101, the locking states of the first locking portion (first locking tooth row 113) on the outer surface of the second holding piece 120 and the second locking portion (second locking tooth row 123) on the inner surface of the second holding piece 120 are formed and maintained. That is, it is possible to hold the wiring and pipe material P with the first holding piece 110 and the second holding piece 120 by a simple and intuitive operation of overlapping the second holding piece 120 from the outside of the holding space 101 to the first holding piece 110. On the other hand, the first locking portion and the second locking portion are relatively easily unlocked by separating from each other in a direction different from the locking direction. In contrast, the wiring and pipe material holder 100 of the present embodiment has two separating pieces 121, 121 having free ends independent of each other arranged side by side at the tip portion of the second holding piece 120, and the second locking tooth rows 123 are provided on the respective separating pieces 121, thereby preventing the first locking portion and the second locking portion from being inadvertently unlocked easily. That is, the second locking tooth row 123 of one separating piece 121 and the second locking tooth row 123 of the other separating piece 121 can each independently form a locking state with each opposing first locking tooth row 113 and can be separated from each first locking tooth row 113. That is, in order to release the holding of the wiring and pipe material P, it is necessary to operate the two separating pieces 121, 121 so that the second locking portion is separated from the first locking portion respectively. Even if a force in the direction of separating the first locking portion and the second locking portion is unexpectedly applied to one of the two separating pieces 121 and the locking state is released, since the locking state of the other separating piece 121 is maintained, it is suppressed that the holding of the wiring and pipe material P is completely released. Since the situation where a force in the direction of separating the first locking portion and the second locking portion is unexpectedly applied to both of the two separating pieces 121, 121 is extremely rare, the configuration of the present embodiment effectively prevents the holding of the wiring and pipe material P from being inadvertently released.Therefore, the wiring and pipe material holder 100 of the present embodiment can stably maintain the holding state of the wiring and pipe material P and enable the wiring and pipe material P to be held with a simpler operation.

[0086] Second, according to the wiring and pipe material holder 100 of the present embodiment, by engaging the engaging portion 118 formed to protrude from the first side portion 111a in the arrangement direction of the wiring and pipe material holder 100 with the engaged portion 119 provided on the second side portion 111b in the arrangement direction of the wiring and pipe material holder 100, one wiring and pipe material holder 100 and another wiring and pipe material holder 100 can be connected in the arrangement direction intersecting the arrangement direction of the wiring and pipe material P. Further, the engaging portion 118 is displaceable so as to change the protruding amount in the arrangement direction. Thereby, when the other wiring and pipe material holder 100 is not connected to the first side portion 111a side of one wiring and pipe material holder 100, in order to prevent the engaging portion 118 from interfering with a structure such as a wall (wall material 13), by displacing the engaging portion 118 to a state where the protruding amount is suppressed, the space required for installing the wiring and pipe material holder 100 can be made space-saving. Therefore, the wiring and pipe material holder 100 of the present embodiment can be connected to another wiring and pipe material holder 100 and enables the wiring and pipe material P to be arranged even in a narrower space.

[0087] Thirdly, according to the wiring and pipe material holder 100 of the present embodiment, an annular holding space 101 surrounding the wiring and pipe material P is formed by the tip sides of the first holding piece 110 and the second holding piece 120 overlapping each other. By increasing the overlapping amount and reducing the holding space 101, it is possible to hold wiring and pipe materials P (PS, PL) of different diameters. When proceeding with the overlapping of the first holding piece 110 and the second holding piece 120 to hold a wiring and pipe material P of a predetermined diameter, a hinge side space 105 as a gap is inevitably formed between the hinge 130 and the holding space 101. In contrast, an auxiliary piece 140 rising into the holding space 101 with the tip from the inner surface of the first holding piece 110 as a free end is provided. The auxiliary piece 140 is located between the wiring and pipe material P disposed in the holding space 101 and the hinge 130, and has a contact portion 142 capable of contacting the outer peripheral surface of the wiring and pipe material P. The auxiliary piece 140 blocks the communication between the holding space 101 and the hinge side space 105 and contacts the wiring and pipe material P disposed in the holding space 101 from the hinge 130 side. Thereby, the auxiliary piece 140 prevents the gripped wiring and pipe material P from escaping from the holding space 101 to the hinge side space 105. Further, the auxiliary piece 140 is configured such that when proceeding with the overlapping of the first holding piece 110 and the second holding piece 120 to reduce the holding space 101 in order to hold the wiring and pipe material P, the tip of the auxiliary piece 140 contacts the inner surface of the second holding piece 120. The auxiliary piece 140 can urge and support the wiring and pipe material P from the hinge side space 105 in conjunction with the overlapping operation of the first holding piece 110 and the second holding piece 120. Therefore, the wiring and pipe material holder 100 of the present embodiment enables more stable holding of wiring and pipe materials P (PS, PL) of different diameters.

[0088] Fourthly, according to the wiring and pipe material holder 100 of the present embodiment, the second holding piece 120 is provided with a release operation portion 128 that projects in the arrangement direction so as to face the outer peripheral surface of the wiring and pipe material P to be held with a gap therebetween. That is, since the release operation portion 128 projects in the arrangement direction from the second holding piece 120 extending in the circumferential direction of the wiring and pipe material P, the gap between the release operation portion 128 and the outer peripheral surface of the wiring and pipe material P is open at least in the circumferential direction of the wiring and pipe material P. The user can operate from a direction intersecting or orthogonal to the wiring and pipe material P to lift the release operation portion 128 to the outside (radial outside) of the holding space 101 by using the gap with a finger or a shaft-shaped operation tool T or the like, so that the second locking tooth row 123 is separated from the first locking tooth row 113 in the radial direction of the wiring and pipe material P, and the locking of the first locking portion and the second locking portion can be released. At this time, since there is sufficient space for the unlocking operation in the direction intersecting or orthogonal to the wiring and pipe material P, the unlocking operation can be performed without being interfered by the wiring and pipe material P extending in the arrangement direction. Therefore, the wiring and pipe material holder 100 of the present embodiment makes the unlocking operation easier.

[0089] Fifthly, according to the wiring and pipe material holder 100 of the present embodiment, when the polymerization of the first holding piece 110 and the second holding piece 120 progresses, engaging prevention means is provided to prevent the engaging teeth of the first locking tooth row 113 and the engaging teeth of the second locking tooth row 123 from engaging in a number of sets less than a specific number N (>1) (that is, 1 to (N-1) sets). That is, when the number of sets of opposing locking teeth increases as the polymerization of the first holding piece 110 and the second holding piece 120 progresses (to a position where they can mesh), before the number of sets of opposing locking teeth reaches N sets, the engaging prevention means prevents the engagement of the opposing locking teeth. Then, when the polymerization further progresses and the number of sets of opposing locking teeth reaches the specific number N, the first engagement of the locking teeth of the first locking tooth row 113 and the locking teeth of the second locking tooth row 123 is made, and the meshing of the locking teeth in the number of sets of the specific number N is formed simultaneously. In the polymerization operation after this first engagement position, the user can feel the touch and sound due to the meshing of the locking teeth. In other words, since the engaging prevention means does not form the meshing of the locking teeth in a number of sets less than N sets, in the operation of tightening the wiring and pipe material P for advancing the polymerization of the first holding piece 110 and the second holding piece 120, the user is not given the misunderstanding that the tightening operation is completed due to an engagement in an insufficient number of sets (less than the specific number N). Therefore, the wiring and pipe material holder 100 of the present embodiment can prevent the user from misjudging the completion of the tightening operation.

[0090] [Second Embodiment] The wiring and pipe material holder 200 of the second embodiment of the present invention is fixed to a structure such as a construction material or a wall material, and is used for the purpose of arranging wiring and pipe materials with respect to the structure, similar to the first embodiment. In this embodiment, the structure to which the wiring and pipe material holder 200 is fixed is a construction material 21 having an installation surface (or arrangement surface) on one side, and the wiring and pipe material P is exemplified as a straight pipe. Hereinafter, the configuration of the wiring and pipe material holder 200 of the present invention will be described. The wiring and pipe material holder 200 of the second embodiment is obtained by additionally providing a sandwiched piece 250 with respect to the wiring and pipe material holder 100 of the first embodiment. And, among the components indicated by three digits, the components having the same lower two digits have the same or similar features unless otherwise explained, and the description thereof will be partially omitted.

[0091] FIGS. 25(a) and (b) are perspective views of a wiring and pipe material holder 200 according to an embodiment of the present invention. FIG. 26 is a front view of the wiring and pipe material holder 200. FIGS. 27(a) to (d) are a plan view, a left side view, a right side view, and a bottom view of the wiring and pipe material holder 200. FIGS. 28 to 31 are cross-sectional views of respective parts of the wiring and pipe material holder 200.

[0092] The wiring and pipe material holder 200 of this embodiment includes a first holding piece 210 extending from the base end to the tip end, a second holding piece 220 extending from the base end to the tip end, cooperating with the first holding piece 210 to surround the wiring and pipe material P and hold it along the arrangement direction, a hinge 230 rotatably connecting the base end side of the first holding piece 210 and the base end side of the second holding piece 220 to each other, an auxiliary piece 240 rising from the inner surface of the first holding piece 210 with the tip end as a free end, and a sandwiched piece 250 extending from the inner surface of the second holding piece 220 from the base end side to the tip end side of the second holding piece 220 with the tip end as a free end into the holding space 201. In the wiring and pipe material holder 200 of this embodiment, the first holding piece 210, the second holding piece 220, the hinge 230, the auxiliary piece 240, and the sandwiched piece 250 are integrally formed.

[0093] As shown in FIGS. 25 to 27, in the original form of the wiring and pipe material holder 200 (which does not hold the wiring and pipe material P), an opening 203 for introducing the wiring and pipe material P inward is formed between the tip of the first holding piece 210 and the tip of the second holding piece 220. Communicating with the opening 203, a holding space 201 for holding the wiring and pipe material P is defined inside the first holding piece 210 and the second holding piece 220. Then, with the hinge 230 as the center, the first holding piece 210 and the second holding piece 220 rotate or displace relative to each other, and an annular holding space 201 that surrounds the wiring and pipe material P in the circumferential direction can be formed by the tip portion of the first holding piece 210 and the tip portion of the second holding piece 220 overlapping. At this time, the second holding piece 220 overlaps the first holding piece 210 from the outside (radial outside) of the holding space 201. This closed holding space 201 can be maintained by the engagement of the first locking portion (first locking tooth row 213) of the first holding piece 210 and the second locking portion (second locking tooth row 223) of the second holding piece 220. Further, regardless of whether the opening 203 is open or closed, a hinge-side space 205 is formed as an extra gap where the wiring and pipe material P is not arranged between the holding space 201 and the hinge 230.

[0094] Also, the wiring and pipe material holder 200 can gradually reduce the size of the holding space 201 by gradually advancing the overlap of the tip portions while maintaining the locked state. That is, as the overlap amount of the first holding piece 210 and the second holding piece 220 increases, the locking amount of the first locking portion and the second locking portion increases, or the relative locking positions of the first locking portion and the second locking portion change. FIG. 32 is a schematic cross-sectional view of the wiring and pipe material holder 200 showing the form in which the overlap of the first holding piece 210 and the second holding piece 220 is completely advanced and the holding space 201 is reduced to the maximum.

[0095] In addition, the wiring and pipe material holder 200 of the present embodiment is configured to be connectable to other wiring and pipe material holders 200 in the arrangement direction intersecting the installation direction. That is, the wiring and pipe material holder 200 includes a connecting mechanism that connects one wiring and pipe material holder 200 and another wiring and pipe material holder 200 adjacent to the one wiring and pipe material holder 200 in the arrangement direction intersecting the installation direction. The connecting mechanism is composed of an engaging portion 218 and an engaged portion 219. However, in the present embodiment, unlike the first embodiment, the engaging portion 218 does not tilt inside the first side portion 211a so as to change its protruding amount.

[0096] Hereinafter, each component of the wiring and pipe material holder 200 of the present embodiment will be described in detail.

[0097] The first holding piece 210 extends from the base end side to the tip end side, and includes a block-shaped wall portion located from the base end side to the center, and an arm-shaped wall portion erected on the tip end side of the block-shaped wall portion. This arm-shaped wall portion forms the tip portion of the first holding piece 210. In addition, a thin hinge 230 is continuously provided at the base end of the block-shaped wall portion of the first holding piece 210. The first holding piece 210 includes a base portion 211 as a base fixed to the structure, a first gripping portion 212 that is continuously provided to the base portion 211 and forms an arc-shaped recess on the inner surface for gripping the wiring and pipe material P, and a first locking portion (first locking tooth row 213) for maintaining the surrounding of the wiring and pipe material P by the holding space 201.

[0098] The first gripping portion 212 forms an arc-shaped recess so as to grip the wiring and pipe material P above the base portion 211 and extending in the direction from the base end to the tip end of the first holding piece 210. On the tip end side of the first holding piece 210, a part of the first gripping portion 212 rises with respect to the base portion 211. The first gripping portion 212 is formed as a curved surface having a substantially arc shape in a cross-sectional view on the inner surface of the recess facing the second holding piece 220. This curved surface is defined as a first arc portion. The arc shape of the first arc portion is defined to coincide with the circumference of the corresponding maximum diameter (that is, the outer peripheral shape of the wiring and pipe material PL).

[0099] On the outer surface of the arm-shaped wall portion of the first holding piece 210 that is curved in an arc shape, as a first locking portion, a first locking tooth row 213 composed of a plurality of locking teeth formed continuously in the progress direction of polymerization is formed. Note that the first locking tooth row 213, the blocking wall portion 214, the dividing wall 215, and the concave strip portion 216 provided on the first holding piece 210 have the same form and function as those in the first embodiment, and thus detailed descriptions thereof are omitted.

[0100] The second holding piece 220 is composed of a strip extending in an arch shape from the base end side to the tip end side. The second holding piece 220 has a base end portion curved in an arc shape and a tip end portion that is continuously provided with the base end portion and is more gently curved. A thin hinge 230 is continuously provided at the base end portion of the second holding piece 220. The curved shape of the tip end portion of the second holding piece 220 corresponds to the curved shape of the outer surface of the arm-shaped wall portion of the first holding piece 210 in order to polymerize with the tip end portion of the first holding piece 210.

[0101] At the tip end portion of the second holding piece 220, separation pieces 221 separated in the width direction within a range of a predetermined length from the circumferential tip end are provided. The two separation pieces 221 have free ends independent of each other. One separation piece and the other separation piece of the two separation pieces 221 can be elastically bent and deformed radially inward and outward around their base ends independently of each other. Also, the two separation pieces 221 are formed side by side in the width direction orthogonal to the extending direction of the second holding piece 220 and are divided in the width direction with a split groove 225 of a predetermined width therebetween. This split groove 225 has a width through which the dividing wall 215 of the first holding piece 210 can be inserted.

[0102] The second holding piece 220 includes a second gripping portion 222 that forms an arc-shaped recess on the inner surface for gripping the wiring and pipe material P, and a second locking portion (second locking tooth row 223) for maintaining the surrounding of the wiring and pipe material P by the holding space 201.

[0103] The second gripping portion 222 forms an arc-shaped recess so as to grip the wiring and pipe material P along the extending direction from the proximal end to the distal end of the second holding piece 220. The second gripping portion 222 is formed as a curved surface that is substantially arc-shaped in cross-section on the inner surface of the recess facing the first holding piece 210. This curved surface is defined as the second arc portion. The second arc portion is located on the proximal end side of the second gripping portion 222. The arc shape of the second arc portion is defined to match the circumference of the corresponding maximum diameter (that is, the outer peripheral shape of the wiring and pipe material PL).

[0104] Further, the second holding piece 220 is provided with an escape portion 227 that extends radially outward on the distal end side of the second arc portion so as to form a space for allowing the displacement of the held piece 250 outward from the holding space 201. That is, the escape portion 227 is a portion that forms a space between the inner surface of the second holding piece 220 and the outer surface of the held piece 250 in which the held piece 250 can tilt.

[0105] On the inner surface of the distal end portion of the second holding piece 220, a second locking tooth row 223 composed of a plurality (here, three) of locking teeth continuously formed in the progress direction of polymerization is formed as a second locking portion. Since the second locking tooth row 223, the rib portion 224, the dividing groove 225, and the release operation portion 228 provided on the second holding piece 220 have the same form and function as those in the first embodiment, detailed description thereof is omitted.

[0106] The auxiliary piece 240 is provided to prevent the wiring and pipe material P held in the holding space 201 from escaping into the hinge-side space 205. The auxiliary piece 240 is an arc-shaped strip that rises from the inner surface of the first holding piece 210 with its tip as a free end toward the inner surface of the second holding piece 220 with a predetermined protruding length. The auxiliary piece 240 is arranged to be located between the wiring and pipe material P arranged in the holding space 201 and the hinge 230. In particular, the auxiliary piece 240 is connected to the base end of the first arc portion and is arranged offset toward the hinge 230 side from the center of the holding space 201 of the first holding piece 210. In the present embodiment, the auxiliary piece 240 rises in the space on the hinge 230 side rather than in the holding space 201 when holding the wiring and pipe material PS with the corresponding minimum diameter. Further, the auxiliary piece 240 stands upright so as to face the inner surface of the tip portion of the first holding piece 210. And on the hinge 230 side of the auxiliary piece 240, a space is formed that allows the auxiliary piece 240 to tilt toward the hinge 230 side. The space is a retraction space for the inner surface (the side that contacts the wiring and pipe material P) of the auxiliary piece 240 to retract to a position where it is continuous with the inner surface of the second holding piece 220. Furthermore, the distance between the tip of the auxiliary piece 240 and the tip of the first holding piece 210 is smaller than the diameter of the wiring and pipe material PL with the maximum diameter.

[0107] The auxiliary piece 240 includes a base end portion 241 that is elastically bendable and deformable on its base end side, and a contact portion 242 that can contact the outer peripheral surface of the wiring and pipe material P. The base end portion 241 is a relatively thin portion of the auxiliary piece 240 and assists the elastic tilting of the auxiliary piece 240. Also, the contact portion 242 has an arc-shaped curved surface facing the tip side of the first holding piece 210 for contacting the outer peripheral surface of the wiring and pipe material P. The curved surface of the contact portion 242 is defined to coincide with the circumference of the corresponding maximum diameter (that is, the outer peripheral shape of the wiring and pipe material PL).

[0108] As shown by the phantom line in Fig. 28, the contact portion 242 is elastically displaceable so as to tilt from the initial position about the base end portion 241 toward both the hinge 230 side and the tip side. In particular, when introducing the wiring and pipe material PL of the corresponding maximum diameter into the holding space 201, the auxiliary piece 240 tilts toward the hinge 230 side and cooperates with the inner surface of the tip portion of the first holding piece 210 facing the inner surface of the contact portion 242 to sandwich the wiring and pipe material PL, thereby also acting to temporarily hold the wiring and pipe material PL.

[0109] Furthermore, the auxiliary piece 240 is configured such that when reducing the holding space 201 in which the wiring and pipe material P is disposed, the tip of the auxiliary piece 240 abuts against the inner surface of the second holding piece 220 (without tilting the auxiliary piece 240 toward the hinge 230 side). As shown in Fig. 32, when the first holding piece 210 and the second holding piece 220 are completely overlapped, the tip portion of the auxiliary piece 240 is at a position where it interferes with the inner surface of the second holding piece 220 in the initial position (phantom line). Therefore, the auxiliary piece 240 is pressed from the hinge 230 side toward the tip side of the second holding piece 220 by the inner surface of the second holding piece 220 and is moved along with the tip side of the second holding piece 220 from the initial position, tilting toward the center side of the holding space 201. In this way, the position and the protruding length of the auxiliary piece 240 are determined such that the tip of the auxiliary piece 240 abuts or presses against the inner surface (inner surface of the second arc portion) of the second holding piece 220.

[0110] The sandwiched piece 250 extends from the inner surface of the second holding piece 220 from the proximal end side to the distal end side with the distal end as a free end, and is configured to be sandwiched between the wiring and pipe material P disposed in the holding space 201 and the first holding piece 210 or the second holding piece 220. The outer surface of the sandwiched piece 250 is spaced apart from the inner surface of the second holding piece 220 and extends in a predetermined length in the circumferential direction so as to face the inner surface of the second holding piece 220. The sandwiched piece 250 has a thin plate-shaped base end portion 251 that can be bent and deformed at the base end side, an arc plate-shaped extending portion 252 extending from the base end portion 251, and a sandwiched portion 253 that expands in the inner and outer direction (radial direction) of the holding space 201 at the distal end side of the extending portion 252 and has a tapered distal end. As shown by the virtual line in FIG. 28, the sandwiched piece 250 can be displaced so as to tilt or rotate radially outward due to the bending deformation of the base end portion 251.

[0111] The sandwiched piece 250 has an arcuate inner surface facing the center side of the holding space 201 from the base end to the distal end. The inner surface of the sandwiched piece 250 is defined to coincide with the circumference of the corresponding maximum diameter (that is, the outer peripheral shape of the wiring and pipe material PL). That is, the first arc portion of the first holding piece 210, the second arc portion of the second holding piece 220, the inner surface of the contact portion 242, and the inner surface of the sandwiched piece 250 have the same curvature and are configured to be located on the same circumference of the diameter of the wiring and pipe material PL. Further, a space for allowing the displacement of the sandwiched piece 250 outward of the holding space 201 is provided between the outer surface of the sandwiched piece 250 and the inner surface of the second holding piece 220. The space is formed inside the relief portion 227 of the second holding piece 220.

[0112] The clamped portion 253 is formed to bulge from the outer surface of the extending portion 252, which extends with a substantially uniform thickness, to the outside (radial outside) of the holding space 201. The clamped portion 253 gradually thickens from its base end to the center, has the thickest portion at the substantially central portion, and gradually thins toward the tip from there. Further, the clamped portion 253 has an arcuate outer surface facing the radial outside at the tip-side portion where it becomes thinner. The outer surface of the tip-side portion of the clamped portion 253 is an arcuate surface having the same or an approximate curvature as the first arc portion so that the clamped portion 253 can be in sliding contact with the first arc portion in the circumferential direction on the first arc portion.

[0113] Then, as shown in FIG. 32, in a state where the superposition of the first holding piece 210 and the second holding piece 220 is completely advanced and the holding space 201 is reduced as much as possible, the outer surface of the clamped portion 253 is displaced so as to be in pressure contact with the first arc portion. At this time, the clamped portion 253 of the clamped piece 250 is arranged to face the contact portion 242 of the auxiliary piece 240 via the center of the holding space 201. And the clamped portion 253 functions so as to effectively fill the surplus space (that is, the space near the tip of the first holding piece 210) between the inner surface of the first holding piece 210 and the inner surface of the auxiliary piece 240. Further, as the superposition of the first holding piece 210 and the second holding piece 220 progresses and the overlap between the clamped portion 253 and the first holding piece 210 increases, the tip of the clamped piece 250 slides on the inner surface of the first holding piece 210, and the space (surface-to-surface distance) between the auxiliary piece 240 and the clamped portion 253 is configured to be gradually reduced. At this time, the tip of the clamped piece 250 is pressed against the inner surface of the first holding piece 210, and the clamped portion 253 is bent and deformed so as to be separated from the inner surface of the second holding piece 220.

[0114] Next, an installation structure 20 in which the wiring and pipe material holder 200 of the present embodiment holds and disposes the wiring and pipe material PS having the corresponding minimum diameter with respect to the construction material 21 (structure) will be described. FIG. 33 is a schematic perspective view of the installation structure 20. FIG. 34 is a schematic front view of the installation structure 20. FIG. 35 is a cross-sectional view taken along line E'-E' of the installation structure 20. FIG. 36 is a cross-sectional view taken along line F'-F' of the installation structure 20.

[0115] In the installation structure 20, the wiring and pipe material PS is held in the closed holding space 201 of the wiring and pipe material holder 200. As shown in FIG. 35, the tip portions of the first holding piece 210 and the second holding piece 220 overlap each other, and the second locking tooth row 223 meshes with the first locking tooth row 213 from the radially outer side, so that the closed state of the holding space 201 is maintained. In the installation structure 20 for holding the wiring and pipe material PS having the corresponding minimum diameter, the three locking teeth of the second locking tooth row 223 are engaged with the three locking teeth on the rearmost end side of the first locking tooth row 213 so that the overlapping amount of the first holding piece 210 and the second holding piece 220 is maximized. As a result, the state in which the holding space 201 surrounding the wiring and pipe material PS is minimized is maintained.

[0116] In the installation structure 20, as shown in FIG. 35, the first gripping portion 212 of the first holding piece 210, the contact portion 242 of the auxiliary piece 240, and the gripped portion 253 of the gripped piece 250 are each pressed against the outer peripheral surface of the wiring and pipe material PS, whereby the wiring and pipe material PS is gripped. As a result, the wiring and pipe material PS is stably gripped so as not to float within the holding space 201.

[0117] As shown in Fig. 35, the auxiliary piece 240 is positioned between the outer peripheral surface of the wiring and pipe material PS and the hinge 230. The auxiliary piece 240 blocks the communication between the holding space 201 and the hinge-side space 205. Further, the tip of the auxiliary piece 240 is engaged with the inner surface of the second gripping portion 222 of the second holding piece 220 in a posture tilted from the original position toward the center side of the holding space 201. The auxiliary piece 240 is pressed from the hinge 230 side toward the center of the holding space 201 (the tip side of the first holding piece 210 or the second holding piece 220) by the inner surface of the second gripping portion 222. And since the auxiliary piece 240 supports the wiring and pipe material PS from the hinge 230 side, it does not tilt further into the hinge-side space 205. Therefore, the auxiliary piece 240 prevents the wiring and pipe material PS from escaping from the holding space 201 to the hinge-side space 205. Further, the auxiliary piece 240 is stretched and disposed between the inner surface of the first holding piece 210 and the inner surface of the second holding piece 220. As a result, the fulcrum of the rotation of the second holding piece 220 with respect to the first holding piece 210 moves from the hinge 230 to the tip of the auxiliary piece 240, and smooth rotation in the direction of retracting the overlapping of the first holding piece 210 and the second holding piece 220 centered on the hinge 230 is hindered. As a result, it is possible to more firmly maintain the locked state between the first locking portion and the second locking portion.

[0118] Further, the sandwiched piece 250 is sandwiched between the wiring and pipe material PS disposed in the holding space 201 and the first holding piece 210 at a position different from the auxiliary piece 240. Here, the entire sandwiched portion 253 is sandwiched between the wiring and pipe material PS and the inner surface of the first holding piece 210. In other words, the sandwiched portion 253 occupies the surplus space between the wiring and pipe material PS and the inner surface on the tip side of the first holding piece 210. The sandwiched piece 250 is disposed opposite to the auxiliary piece 240 with the wiring and pipe material PS interposed therebetween. Further, the tapered tip of the sandwiched portion 253 enters the gap between the inner surface of the first holding piece 210 and the outer peripheral surface of the wiring and pipe material PS and fills the gap. At this time, the arc-shaped outer surface of the sandwiched portion 253 is in pressure contact with the first arc portion, and the sandwiched portion 253 is biased toward the center side of the holding space 201. That is, the sandwiched piece 250 biases the wiring and pipe material PS disposed in the holding space 201 from the opposite side of the auxiliary piece 240 toward the center of the holding space 201. Thereby, the auxiliary piece 240 and the sandwiched piece 250 act in cooperation to hold the wiring and pipe material PS at the center of the holding space 201. Therefore, in the installation structure 20, the wiring and pipe material holder 200 stably holds the wiring and pipe material PS.

[0119] Furthermore, the auxiliary piece 240 acts to press the inner surface of the second holding piece 220 radially outward, and the sandwiched piece 250 acts to press the inner surface of the first holding piece 210 radially outward. By this pressing force, the opposing surfaces (superimposing surfaces) of the tip portion of the first holding piece 210 and the tip portion of the second holding piece 220 are biased in a direction approaching each other. Thereby, the radial engagement of the first locking tooth row 213 and the second locking tooth row 223 becomes stronger.

[0120] FIG. 37 shows a different form of the installation structure 20-1 in which the wiring and pipe material PL with the largest diameter among the corresponding wiring and pipe materials P is arranged with respect to the installation structure 20 of FIG. 35. In the installation structure 20-1, the wiring and pipe material PL is held in the closed holding space 201 of the wiring and pipe material holder 200. The tip portions of the first holding piece 210 and the second holding piece 220 overlap each other, and the second locking tooth row 223 meshes with the first locking tooth row 213 from the radially outer side, thereby maintaining the closed state of the holding space 201. In the installation structure 20-1 for holding the wiring and pipe material PL having the corresponding maximum diameter, three locking teeth of the second locking tooth row 223 are engaged with the three locking teeth on the most distal side of the first locking tooth row 213 so that the overlapping amount of the first holding piece 210 and the second holding piece 220 is minimized. By circumferentially locking the locking surfaces of the first locking tooth row 213 and the second locking tooth row 223, the second holding piece 220 is restricted from relatively moving in the direction in which the overlapping moves backward with respect to the first holding piece 210. As a result, the holding space 201 surrounding the wiring and pipe material PL is maintained in a state where it is maximized.

[0121] And, as shown in FIG. 37, the arc portion of the first gripping portion 212, the arc portion of the second gripping portion 222, the inner surface of the auxiliary piece 240, and the inner surface of the sandwiched piece 250 are each in contact with the outer peripheral surface of the wiring and pipe material PL, whereby the wiring and pipe material PL is gripped. At this time, the first arc portion, the second arc portion, and the inner surfaces of the contact portion 242 and the sandwiched portion 253 are located on the same circumference that substantially coincides with the outer peripheral surface of the wiring and pipe material PL. Therefore, the wiring and pipe material PL is stably gripped without a gap so as not to float within the holding space 201 by the wiring and pipe material holder 200. When holding the wiring and pipe material PL having the corresponding maximum diameter, since the holding position of the wiring and pipe material PL is determined at one location within the holding space 201, it is not necessary to check the position of the wiring and pipe material PL or align the wiring and pipe material PL.

[0122] Further, the auxiliary piece 240 is located between the outer peripheral surface of the wiring and pipe material PL and the hinge 230. The auxiliary piece 240 is tilted to a position close to the hinge 230. And the auxiliary piece 240 blocks the communication between the holding space 201 and the hinge side space 205. Further, the auxiliary piece 240 takes a posture of retreating from the original position toward the hinge 230 side, and the auxiliary piece 240 is separated from the inner surface of the second holding piece 220. That is, when holding the wiring and pipe material PL with the maximum diameter, the auxiliary piece 240 retreats to a position where it is not pressed (or moved along) toward the tip side by the inner surface of the second holding piece 220. On the other hand, the sandwiched piece 250 is in contact with the outer peripheral surface of the wiring and pipe material PL in a state of retreating to the relief portion 227 on the radially outer side so as to contact the inner surface of the second holding piece 220. The sandwiched piece 250 is sandwiched between the wiring and pipe material PL arranged in the holding space 201 and the inner surface of the second holding piece 220. Also, the auxiliary piece 240 and the sandwiched piece 250 are arranged to face each other with the wiring and pipe material PL therebetween. The auxiliary piece 240 and the sandwiched piece 250 bias the wiring and pipe material PL toward the center side of the holding space 201 and toward the center of the holding space 201 by their elastic restoring forces. Thereby, similarly when holding the wiring and pipe material PL with the corresponding maximum diameter, the auxiliary piece 240 and the sandwiched piece 250 act in cooperation to hold the wiring and pipe material PL at the center of the holding space 201. Therefore, in the installation structure 20-1, the wiring and pipe material holder 200 stably holds the wiring and pipe material PL.

[0123] FIG. 38 shows an installation structure 20-2 in another form in which a wiring and pipe material PM with an intermediate diameter among the corresponding wirings and pipe materials P is arranged with respect to the installation structure 20 of FIG. 35. In the installation structure 20-2, the wiring and pipe material PM is held in the closed holding space 201 of the wiring and pipe material holder 200. The tip portions of the first holding piece 210 and the second holding piece 220 overlap each other, and the second locking tooth row 223 meshes with the first locking tooth row 213 from the radially outer side, thereby maintaining the closed state of the holding space 201.

[0124] In the installation structure 20-2, similar to the installation structure 20, the auxiliary piece 240 is located between the outer peripheral surface of the wiring and pipe material PM and the hinge 230. The tip of the auxiliary piece 240 engages with the inner surface of the first holding piece 210, thereby blocking the communication between the holding space 201 and the hinge-side space 205. Further, the sandwiched piece 250 is sandwiched between the wiring and pipe material PM disposed in the holding space 201 and the first holding piece 210 at a position different from that of the auxiliary piece 240. Here, a part of the sandwiched portion 253 (only the tip portion) is sandwiched between the wiring and pipe material PM and the first holding piece 210. The sandwiched piece 250 is disposed opposite to the auxiliary piece 240 with the wiring and pipe material PM interposed therebetween. Also, the tapered tip of the sandwiched portion 253 enters the gap between the inner surface of the first holding piece 210 and the outer peripheral surface of the wiring and pipe material PM and fills the gap. At this time, the arc-shaped outer surface of the sandwiched portion 253 is in pressure contact with the first arc portion, and the sandwiched portion 253 is biased toward the center side of the holding space 201. That is, the sandwiched piece 250 biases the wiring and pipe material PM disposed in the holding space 201 from the opposite side of the auxiliary piece 240 toward the center of the holding space 201. Thereby, the auxiliary piece 240 and the sandwiched piece 250 cooperate to act so as to hold the wiring and pipe material PM at the center of the holding space 201. Therefore, in the installation structure 20-2, the wiring and pipe material holder 200 stably holds the wiring and pipe material PM.

[0125] That is, as shown in FIGS. 35, 37, and 38, the wiring and pipe material holder 200 can stably hold wiring and pipe materials P (PS, PL, PM) of different diameters from the corresponding minimum diameter to the corresponding maximum diameter by appropriately displacing the auxiliary piece 240 and the sandwiched piece 250 according to the diameter of the wiring and pipe material P to be gripped.

[0126] Next, with reference to FIG. 39, each step of the method of gripping the wiring and pipe material PS of the corresponding minimum diameter with the wiring and pipe material holder 200 will be exemplified.

[0127] First, open the opening 203 of the wiring and pipe material holder 200, and insert the wiring and pipe material PS into the holding space 201 through the opening 203. As shown in Fig. 39(a), place the wiring and pipe material PS between the tip of the first holding piece 210 and the auxiliary piece 240. At this time, the wiring and pipe material P is placed near the center of the holding space 201. Then, rotate the second holding piece 220 around the hinge 230 in the direction of closing the opening 203. Superimpose the tip of the first holding piece 210 and the tip of the second holding piece 220, and engage the first locking tooth row 213 and the second locking tooth row 223. Here, by the engagement preventing means, it is prevented that two or less locking teeth of the second locking tooth row 223 engage with the locking teeth of the first locking tooth row 213. After the superposition proceeds to the position where the three sets of locking teeth face each other, the locking state by the first locking portion and the second locking portion is formed for the first time (see Fig. 17).

[0128] After the locking state is first formed, when the superposition of the first holding piece 210 and the second holding piece 220 proceeds, as shown in Fig. 39(b), the inner surface of the second holding piece 220 abuts against the tip of the auxiliary piece 240, and the outer surface of the sandwiched piece 250 abuts against the inner surface of the first holding piece 210. At this time, the auxiliary piece 240 and the sandwiched piece 250 face each other at a predetermined surface-to-surface distance. As the superposition proceeds, the auxiliary piece 240 and the sandwiched piece 250 slide or slide circumferentially on the inner surfaces of the second holding piece 220 and the first holding piece 210, and elastically tilt toward the center of the holding space 201, and the surface-to-surface distance between the auxiliary piece 240 and the sandwiched piece 250 decreases. As the overlap between the sandwiched portion 253 of the sandwiched piece 250 and the first holding piece 210 increases, the surface-to-surface distance between the auxiliary piece 240 and the sandwiched piece 250 decreases, and the space between the contact portion 242 of the auxiliary piece 240 and the sandwiched portion 253 shrinks. Then, if the tightening operation is continued so as to reduce the holding space 201, as shown in Fig. 39(c), the inner surface of the sandwiched portion 253 (or the inner surface of the contact portion 242) abuts against the outer peripheral surface of the wiring and pipe material PS.

[0129] Further, when operating to strongly tighten the second holding piece 220 against the first holding piece 210, as shown in FIG. 39(d), the wiring and pipe material PS is pinched at the center of the holding space 201 between the auxiliary piece 240 and the held piece 250. The auxiliary piece 240 and the held piece 250 act so as to bias or press the wiring and pipe material PS toward the center side of the holding space 201 so as to cooperate to hold the wiring and pipe material PS at the center of the holding space 201. As a result, it is possible to firmly grip the wiring and pipe material PS by the wiring and pipe material holder 200 and stably hold it in the holding space 201. In addition, in a series of steps, the wiring and pipe material PS is suppressed from being largely moved from the initial placement position within the holding space 201 by the auxiliary piece 240 and the held piece 250 interlocking around the wiring and pipe material PS.

[0130] Referring to FIG. 40, each step of a method of gripping a wiring and pipe material PL having a corresponding maximum diameter with the wiring and pipe material holder 200 will be illustrated.

[0131] First, the opening 203 of the wiring and pipe material holder 200 is opened, and the wiring and pipe material PL is inserted into the holding space 201 through the opening 203. As shown in FIG. 40(a), the wiring and pipe material PL is disposed between the tip portion of the first holding piece 210 and the auxiliary piece 240. At this time, since the distance between the tip portion of the first holding piece 210 and the auxiliary piece 240 is smaller than the diameter of the wiring and pipe material PL, while elastically tilting the auxiliary piece 240 radially outward, the wiring and pipe material PL is placed near the center of the holding space 201. Due to the elastic restoring force of the auxiliary piece 240, the wiring and pipe material PL is temporarily held between the first holding piece 210 and the auxiliary piece 240.

[0132] Then, as shown in Fig. 40(b), when the second holding piece 220 is rotated about the hinge 230 in the direction to close the opening portion 203, the inner surface of the sandwiched piece 250 comes into contact with the outer surface of the wiring and pipe material PL. When the polymerization further proceeds from this state, as shown in Fig. 40(c), the inner surface of the sandwiched piece 250 slides on the outer surface of the wiring and pipe material PL, and the sandwiched piece 250 tilts toward the relief portion 227 on the radially outer side. Then, the tip portions of the first holding piece 210 and the second holding piece 220 are polymerized, and the first locking tooth row 213 and the second locking tooth row 223 are engaged. Then, as shown in Fig. 40(d), the sandwiched piece 250 completely retracts, and its extended portion 252 is sandwiched between the wiring and pipe material PL and the second holding piece 220. Then, the first holding piece 210, the second holding piece 220, the auxiliary piece 240, and the sandwiched piece 250 are in pressure contact with the outer peripheral surface of the wiring and pipe material PL without any gaps. As a result, it is possible to firmly hold the wiring and pipe material PL by the wiring and pipe material holder 200 and stably hold it in the holding space 201. In the above series of steps, by maintaining the state in which the wiring and pipe material PL is temporarily held, it is suppressed that the wiring and pipe material PL is largely moved from the initial placement position within the holding space 201.

[0133] In addition, in the above steps of the method for gripping the wiring and pipe material P by the wiring and pipe material holder 200 of the present embodiment, since the fixing portion (insertion portion 211e) for fixing to the structure is provided on the first holding piece 210 and the holding portion (holding space 201) is arranged above the fixing portion, even if the diameter of the wiring and pipe material P to be held is different, it is possible to keep the relative holding position of the wiring and pipe material P with respect to the fixing portion constant. Therefore, the positioning of the wiring and pipe material P can be easily performed.

[0134] Hereinafter, the effects of the wiring and pipe material holder 200 according to an embodiment of the present invention will be described. Note that the description of the effects common to the wiring and pipe material holder 100 will be omitted.

[0135] According to the wiring and pipe material holder 200 of the present embodiment, the sandwiched piece 250 is sandwiched between the wiring and pipe material P disposed in the holding space 201 and the first holding piece 210 or the second holding piece 220 at a position different from the auxiliary piece 240, thereby further filling the gap (surplus space) in the holding space 201 and enabling the wiring and pipe material P to be held more stably. Further, the sandwiched piece 250 has a base end portion 251 that can be bent and deformed on the base end side, and a sandwiched portion 253 that expands in the inner and outer directions of the holding space 201 on the tip side of the base end portion 251 and has a tapered tip. The sandwiched portion 253 that expands in the inner and outer directions of the holding space 201 can be elastically tilted by the bending deformation of the base end portion 251. Thereby, in the space on the tip side of the first holding piece 210 and the second holding piece 220, it is possible to further reduce the gap between the first holding piece 210 or the second holding piece 220 and the wiring and pipe material P. Further, since the tip of the sandwiched piece 250 is tapered, it can enter the gap between the first holding piece 210 and the wiring and pipe material P (disposed in the holding space 201) and effectively fill the gap. And as the overlap between the sandwiched portion 253 and the first holding piece 210 increases, the space between the auxiliary piece 240 and the sandwiched portion 253 shrinks. The sandwiched piece 250 biases the wiring and pipe material P disposed in the holding space 201 from the opposite side of the auxiliary piece 240 toward the center of the holding space 201. Thereby, the auxiliary piece 240 and the sandwiched piece 250 constitute a part of the outer edge of the holding space 201 on their inner surfaces and act in cooperation to hold the wiring and pipe material P at the center of the holding space. As a result, the wiring and pipe material holder 200 can hold the wiring and pipe material P more stably.

[0137] (1) The wiring and pipe material holder of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe material holder of the above embodiment, the first locking portion is divided into two rows, but the present invention is not limited to this. That is, the dividing wall may be omitted from the first holding piece, and the first locking portion may not be divided in the width direction. Further, even if a dividing wall is provided on the first holding piece, only a part of the first locking portion may be divided in the width direction by the dividing wall.

[0138] (2) The wiring and pipe material holder of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe material holder of the above embodiment, a fixing portion fixed to the structure is provided on the first holding piece, but in the present invention, a fixing portion (fixing surface or insertion portion) may be provided on the second holding piece.

[0139] (3) The wiring and pipe material holder of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe material holder of the above embodiment, the first holding piece, the second holding piece, and the hinge are integrally formed, but they may be a combination of separate bodies. The rigid first holding piece and the second holding piece may be connected by a shaft-like hinge, and the first holding piece and the second holding piece may rotate about the hinge.

[0140] (4) The wiring and pipe material holder of the present invention is not limited to the configuration of the above embodiment.

In the wiring and pipe material holder of the above embodiment, the number of locking teeth of the first locking tooth row (first locking portion) is large, and the number of locking teeth of the second locking tooth row (second locking portion) is three. And since all the locking teeth of the second locking tooth row engage with the locking teeth of the first locking tooth row simultaneously, the locking position changes according to the overlapping amount of the first holding piece and the second holding piece, but the locking amount (number of engagements) between the first locking portion and the second locking portion is constant. However, the present invention is not limited to this. That is, in the present invention, the second locking tooth row may be composed of a large number of teeth so as to be formed over the entire polymerizable portion of the second holding piece. In such a configuration, as the overlapping amount of the first holding piece and the second holding piece increases, the locking amount between the first locking portion and the second locking portion can increase.
