Description

[Technical Field]

[0001] The present invention relates to a holder for wiring and piping material that holds wiring and piping material. [Background technology]

[0002] BACKGROUND ART Conventionally, various types of holders for wiring and piping materials have been used for fixing to wall surfaces such as the structural surfaces of buildings and the column surfaces of construction materials, in order to support and route wiring and piping materials on the wall surfaces.

[0003] For example, Patent Document 1 discloses a piping fixture for arranging wiring and piping materials side by side. In the following paragraphs, the reference numerals of Patent Document 1 are indicated in parentheses. The piping fixture (10) includes a base (11) fixed to an installation surface, a pair of peripheral walls (12, 13) facing each other at both widthwise ends of the base (11) and forming an opening (14) for inserting piping material (P) between their ends, and protrusions (17, 18) integrally formed with the pair of peripheral walls (12, 13) and shaped to allow wires to be connected. By connecting a wire between the protrusions (17, 18) of the pair of peripheral walls (12, 13), the pair of peripheral walls (12, 13) expand relative to each other, preventing the piping material P from leaking out. Furthermore, a pair of first and second connecting portions (15) and (16) are integrally formed with the base (11) at both widthwise ends. A first connecting portion (15) is provided on the base end side of one of the pair of peripheral walls (12, 13). A second connecting portion (16) connectable to the first connecting portion (15) is provided on the base end side of the other peripheral wall (13) at a position corresponding to the first connecting portion (15). The first connecting portion (15) has a generally channel-shaped cross section that opens outward. The second connecting portion (16) has a generally T-shaped cross section that corresponds to the inner shape of the first connecting portion (15). By inserting and connecting the second connecting portion (16) into the first connecting portion (15) from one widthwise side of the base (11), multiple piping material fasteners (10) can be arranged side by side in the widthwise direction and connected.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-38116 Summary of the Invention [Problem to be solved by the invention]

[0005] The wiring and piping material holder (piping material fixing device) of Patent Document 1 allows for the orderly arrangement of wiring and piping materials by arranging multiple wiring and piping material holders side by side and fastening them to a structure in a connected state. However, a problem with a wiring and piping material holder used alone or a wiring and piping material holder placed at the end of a parallel arrangement of multiple wiring and piping material holders is that the connecting portions protruding to the side interfere with installation. For example, when installing a wiring and piping material holder adjacent to a structure such as a wall, the connecting portions interfere with the wall or other structure, making it impossible to install the wiring and piping material holder unless there is sufficient space for the connecting portions. Therefore, with conventional wiring and piping material holders, the ability to connect to other wiring and piping material holders reduces the flexibility of installation.

[0006] The present invention has been made to solve the above-mentioned problems, and its object is to provide a wiring and piping material holder that can be connected to other wiring and piping material holders and that allows wiring and piping material to be arranged even in narrower spaces. [Means for solving the problem]

[0007] The wiring / piping material holder according to claim 1 is a wiring / piping material holder for holding wiring / piping material, a holding portion that holds wiring and piping materials along the installation direction; a connecting mechanism for connecting one wiring / piping material holder to another wiring / piping material holder adjacent to the one wiring / piping material holder in an arrangement direction intersecting with the arrangement direction, the connecting mechanism includes an engaging portion formed to protrude from a first side portion of the wiring / piping material holder in the arrangement direction, and an engaged portion provided on a second side portion of the wiring / piping material holder in the arrangement direction and configured to be engageable with the engaging portion, The engaging portion is characterized in that it is displaceable so as to change the amount of protrusion in the arrangement direction.

[0008] The wiring / piping material holder described in claim 2 is characterized in that, in the wiring / piping material holder described in claim 1, the engaging portion is connected to the first side portion at its base end and can be displaced in and out of the arrangement direction by rotating around the base end.

[0009] The wiring / piping material holder of claim 3 is the wiring / piping material holder of claim 2, characterized in that the engaging portion is displaceable from a first position where it can be connected to the engaged portion of the other wiring / piping material holder, to a second position where it cannot be connected to the engaged portion of the other wiring / piping material holder.

[0010] The wiring / piping material holder according to claim 4 is the wiring / piping material holder according to any one of claims 1 to 3, further comprising a base having a fixing surface to be fixed to a structure, the holding portion being connected to the opposite side of the fixing surface of the base, the engaging portion and the engaged portion are provided on the first side portion and the second side portion of the base, The engaging portion is characterized in that it can be displaced from a first position where it can be connected to the engaged portion of the other wiring / piping material holder, to a second position where it does not protrude beyond the outer surface of the base.

[0011] The wiring / piping material holder described in claim 5 is characterized in that, in the wiring / piping material holder described in any one of claims 1 to 4, the engaging portion and the engaged portion can be engaged by relative sliding along a direction different from the arrangement direction.

[0012] The wiring / piping material holder described in claim 6 is characterized in that, in the wiring / piping material holder described in any one of claims 1 to 5, the displacement of the engaging portion is regulated when it is engaged with the engaged portion.

[0013] The holder for wiring and piping material according to claim 7 comprises the holder for wiring and piping material according to any one of claims 1 to 6, a base interposed between the wiring / piping material holder and a structure to which the wiring / piping material holder is fixed, The base is characterized by having an abutment wall portion that abuts against the engaging portion of the wiring / piping material holder to restrict displacement of the engaging portion. [Effects of the Invention]

[0014] According to the wiring and piping material holder of claim 1, a protruding engaging portion formed on a first side of the wiring and piping material holder in the arrangement direction engages with an engaged portion provided on a second side of the wiring and piping material holder in the arrangement direction, thereby enabling one wiring and piping material holder to be connected to another wiring and piping material holder in an arrangement direction that intersects with the wiring and piping material installation direction. The engaging portion is also displaceable to change the amount of protrusion in the arrangement direction. This allows the engaging portion to be displaced to a reduced protrusion state to prevent interference with structures such as walls when another wiring and piping material holder is not connected to the first side of one wiring and piping material holder, thereby reducing the space required to install the wiring and piping material holder. Therefore, the wiring and piping material holder of the present invention is connectable to other wiring and piping material holders and allows wiring and piping material to be installed in smaller spaces.

[0015] According to the holder for wiring and piping material described in claim 2, in addition to the effect of the invention of claim 1, the engaging portion extends and retracts in the arrangement direction by rotating around the base end. In other words, the engaging portion can be displaced to a state in which the amount of protrusion is reduced with a simple structure and a simple operation.

[0016] According to the wiring / piping material holder described in claim 3, in addition to the effects of the invention of claim 1 or 2, the engaging portion can be displaced from a first position where it can be connected to the engaged portion of another wiring / piping material holder to a second position where it cannot be connected to the engaged portion of another wiring / piping material holder, thereby effectively reducing the amount of protrusion of the engaging portion.

[0017] According to the wiring and piping material holder described in claim 4, in addition to the effects of any one of the inventions of claims 1 to 3, the engaging portion can be displaced to a second position that does not protrude beyond the outer surface of the base, thereby preventing the engaging portion from interfering with the structure when the first side portion of the base is fixed close to the structure.

[0018] According to the wiring / piping material holder of claim 5, in addition to the effect of any one of claims 1 to 4, the sliding direction when connecting one wiring / piping material holder to another wiring / piping material holder is different from the arranging direction in which the engaging parts are displaced, thereby preventing the engaging parts from displacing in the arranging direction during the connecting operation and enabling a smooth connecting operation.

[0019] According to the wiring / piping material holder of claim 6, in addition to the effect of any one of claims 1 to 5, the displacement of the engaging portion is restricted while it is engaged with the engaged portion, thereby making it possible to stably maintain the engaged state. In particular, it becomes easy to maintain the relative position of one wiring / piping material holder and another wiring / piping material holder without fixing the wiring / piping material holder to a structure, and it becomes possible to fix one wiring / piping material holder and another wiring / piping material holder in a combined state to a structure.

[0020] According to the wiring / piping material holding device of claim 7, it is possible to achieve the effects of any one of the inventions of claims 1 to 6. In particular, by combining a base with the wiring / piping material holder, the protruding state of the engagement portion is maintained, and one wiring / piping material holder can be easily connected to another wiring / piping material holder.

[0022] An embodiment of the present invention will be described below with reference to the drawings. The shapes of the drawings referred to in the following description are conceptual or schematic diagrams for explaining preferred shapes and dimensions, and the dimensional ratios do not necessarily correspond to the actual dimensional ratios. In other words, the present invention is not limited to the dimensional ratios shown in the drawings. Furthermore, the up, down, left, and right directions in the present invention are merely concepts indicating relative positions, and needless to say, these directions can be interchanged and applied.

[0023] A wiring / piping material holder 100 according to one embodiment of the present invention is fixed to a structure such as a building material or a wall material, and is used to install wiring / piping material within the structure. In this embodiment, the structure to which the wiring / piping material holder 100 is fixed is a building material 11 having an installation surface (or installation surface) on one side, and the wiring / piping material P is exemplified as a corrugated flexible pipe. The wiring / piping material P is formed so that peaks (large diameter portions) and valleys (small diameter portions) alternately and continuously in the longitudinal direction. However, this embodiment is merely one example of the present invention, and its use and configuration are not limited thereto as long as they do not deviate from the technical scope of the present invention. The configuration of the wiring / piping material holder 100 according to the present invention will be described below.

[0024] 1(a) and 1(b) are perspective views of a wiring / piping material holder 100 according to one embodiment of the present invention. FIG. 2 is a front view of the wiring / piping material holder 100. FIGS. 3(a) to 3(d) are a plan view, a left side view, a right side view, and a bottom view of the wiring / piping material holder 100. FIGS. 4 to 7 are cross-sectional views of various parts of the wiring / piping material holder 100.

[0025] The wiring / piping material holder 100 of this embodiment is configured to be fixed to a structure and to hold or grip wiring / piping material P in a holding space 101 serving as a holding portion, thereby arranging the wiring / piping material P in a predetermined arrangement direction along the wall surface of the structure. As shown in FIG. 2 , the wiring / piping material holder 100 has a substantially C-shape in front view, defining the holding space 101, which is open at an opening 103. In this embodiment, the wiring / piping material holder 100 is integrally molded from synthetic resin, and the belt-shaped portion is flexible and elastic. Here, the holding space 101 refers to an area in which wiring / piping material P having a predetermined diameter as the object to be held is held, but it can also be interpreted as an area whose outer edge varies according to the diameter (corresponding minimum diameter to opposing maximum diameter) of the wiring / piping material P to be held.

[0026] The wiring / piping material holder 100 is configured to be able to hold two or more types of wiring / piping materials having different diameters ranging from minimum to maximum in the holding space 101. Here, the wiring / piping material with the largest diameter among the corresponding wiring / piping materials P is represented by PL, the wiring / piping material with the largest diameter is represented by PS, and the wiring / piping material with no specified diameter is represented by P. The maximum diameter of the wiring / piping material is determined by the diameter of the longest elongated body whose outer periphery can be enclosed in the (closed) holding space 101. On the other hand, the minimum diameter of the wiring / piping material is determined by the diameter of the smallest elongated body that can be held without moving in the holding space 101. In the case of a corrugated flexible tube, the diameter of the wiring / piping material referred to here is the outer diameter of the ridge portion.

[0027] The wiring / piping material holder 100 of this embodiment includes a first holding piece 110 extending from the base end to the tip, a second holding piece 120 extending from the base end to the tip and cooperating with the first holding piece 110 to surround the wiring / piping material P and hold it along the installation 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 standing up from the inner surface of the first holding piece 110 with its tip as a free end. In the wiring / piping material holder 100 of this 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 / piping material holder 100 (first holding piece 110 and second holding piece 120) extends in a C-shape or annular shape (the direction surrounding the wiring / piping material P) is referred to as the extension direction or circumferential direction, and the direction inward and outward of the holding space 101 (the radial direction of the wiring / piping material P) is referred to as the radial direction. Also, the direction perpendicular to the extension direction of the wiring / piping material holder 100 (first holding piece 110 and second holding piece 120) (the arrangement direction of the wiring / piping material P) is referred to as the width direction. Furthermore, the up-down direction as viewed from the front, which is perpendicular to the bottom surface (fixing surface 111c) of the wiring / piping material holder 100, is referred to as the erection direction.

[0028] As shown in FIGS. 1 to 3 , in the initial state of the wiring / piping material holder 100 (not holding the wiring / piping material P), an opening 103 for introducing the wiring / piping material P is formed between the tip of the first holding piece 110 and the tip of the second holding piece 120. A holding space 101 for holding the wiring / piping material P is defined inside the first holding piece 110 and the second holding piece 120, communicating with the opening 103. When the first holding piece 110 and the second holding piece 120 rotate or displace relatively around the hinge 130, the tip end portion of the first holding piece 110 overlaps the tip end portion of the second holding piece 120, thereby forming an annular holding space 101 that circumferentially surrounds the wiring / piping material P. At this time, the second holding piece 120 overlaps the first holding piece 110 from the outside (radially outside) of the holding space 101. This closed retaining space 101 can be maintained by the engagement of the first locking portion (first locking tooth row 113) of the first retaining piece 110 and the second locking portion (second locking tooth row 123) of the second retaining piece 120. The first locking portion and the second locking portion are released from engagement by moving away from each other in a direction different from the locking direction (i.e., the radial direction). Furthermore, whether the opening portion 103 is open or closed, a hinge-side space 105 is formed between the retaining space 101 and the hinge 130 as an extra gap in which no wiring or piping material P is placed.

[0029] This hinge-side space 105 is a space for allowing bending displacement of the base end of the first holding piece 110 and the base end of the second holding piece 120 around the hinge 130, and is therefore necessarily formed inside the wiring / piping material holder 100. In conventional wiring / piping material holders, when the wiring / piping material P is tightened with a relatively strong pressing force, this hinge-side space acts as an escape space that invites bending deformation or displacement of the wiring / piping material, which can cause problems in the installation of the wiring / piping material P.

[0030] Furthermore, the wiring / piping material holder 100 can gradually reduce the size of the holding space 101 by gradually overlapping the tip portions while maintaining the locked state. That is, as the amount of overlap between the first holding piece 110 and the second holding piece 120 increases, the amount of locking between 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. Figure 8 is a schematic cross-sectional view of the wiring / piping material holder 100 showing the state in which the first holding piece 110 and the second holding piece 120 have been completely overlapped, thereby minimizing the size of the holding space 101.

[0031] Furthermore, the wiring and piping material holder 100 of this embodiment is configured to be connectable to other wiring and piping material holders 100 (which are the same item) in a lining direction that intersects with the installation direction (see FIG. 20, etc.). That is, the wiring and piping material holder 100 has a connecting mechanism that connects one wiring and piping material holder 100 to another wiring and piping material holder 100 adjacent to the one wiring and piping material holder 100 in a lining direction that intersects with the installation direction.

[0032] Furthermore, the wiring / piping material holder 100 of this embodiment is equipped with an engagement prevention means for preventing the engagement of the locking teeth of the first locking tooth row 113 with the locking teeth of the second locking tooth row 123 in a number of sets less than a specific number N (=3>1) regarding the locked state of the first locking portion and the second locking portion. Also, in this embodiment, the second locking tooth row 123 is composed of three locking teeth, and engagement is prevented in a number of sets of locking teeth less than 3. Note that the specific number N, which indicates the number of locking tooth sets required for sufficiently strong engagement, and the number of locking teeth in each locking tooth row can be designed as desired depending on the object to be held, the application, etc.

[0033] Each component of the wiring / piping material holder 100 of this embodiment will be described in detail below.

[0034] The first holding piece 110 extends from the base end side to the tip end side and is composed of 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 110. A thin hinge 130 is connected to the base end of the block-shaped wall portion of the first holding piece 110. The first holding piece 110 is equipped with a base portion 111 as a base to be fixed to a structure, a first gripping portion 112 connected to the base portion 111 and forming an arc-shaped recess on its inner surface for gripping the wiring / piping material P, and a first locking portion (first locking tooth row 113) for maintaining the surrounding of the wiring / piping material P by the holding space 101.

[0035] As shown in FIG. 5, the base 111 extends in the extension direction of the first holding piece 110 and has a first side 111a on the right side in the extension direction when viewed from the front and a second side 111b on the left side in the extension direction when viewed from the front. Here, the first side 111a and the second side 111b are both edges (excluding movable portions) of the first holding piece 110 when viewed from the front. A flat fixing surface 111c is defined on the bottom surface of the base 111. As shown in FIG. 5, a recess 111d for accommodating the head of a fixing screw 15 is provided approximately in the center of the extension direction of the base 111. An insertion portion 111e is formed at the bottom of the recess 111d, which penetrates the base 111 vertically and through which the shank of the screw 15 is inserted when fixing to a structure.

[0036] The first gripping portion 112 forms an arc-shaped recess above the base 111, extending from the base end to the tip of the first holding piece 110, so as to grip the wiring / piping material P. At the tip side of the first holding piece 110, a portion of the first gripping portion 112 rises from the base 111. The first gripping portion 112 is formed as a curved surface that is approximately arc-shaped in cross section on the inner surface of the recess facing the second holding piece 120. This curved surface is defined as a first arc portion. The arc shape of the first arc portion is defined to match the circumference of the corresponding maximum diameter circle (i.e., the outer peripheral shape of the wiring / piping material PL). In other words, the curvature of the first arc portion corresponds to the corresponding maximum diameter circle. The first arc portion also has an arc-shaped plate-shaped rib 112a that fits into the valley of the wiring / piping material P, which is a corrugated flexible tube, and engages the wiring / piping material P in the longitudinal direction.

[0037] The arc-shaped outer surface of the arm-shaped wall of the first holding piece 110 is formed with a first locking tooth row 113, which is made up of multiple locking teeth arranged consecutively in the direction of stacking. In this embodiment, two rows of the first locking tooth rows 113 are aligned circumferentially and spaced apart on both sides of the width of the first holding piece 110. Each first locking tooth row 113 extends over most of the circumferential area of ​​the outer surface of the arm-shaped wall. Each locking tooth of the first locking tooth row 113 has a sloping surface at its tip end and a locking surface that stands substantially perpendicular to the outer surface of the arm-shaped wall on the opposite side. The first locking tooth row 113 allows movement in only one direction relative to the sawtooth-shaped locking teeth of the second locking tooth row 123 (described later) and acts to lock in the other direction. The first locking tooth row 113 has a larger number of locking teeth than the number of locking teeth (minimum number of engagement N) of the second locking tooth row 123. The more locking teeth that make up the first locking tooth row 113, the more it is possible to maintain the engagement between the first holding piece 110 and the second holding piece 120 while reducing the holding space 101. In other words, the maximum amount of overlap between the first locking tooth row 113 and the second locking tooth row 123 is determined by the number of locking teeth of the one with the larger number of locking teeth.

[0038] 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 end side of the first holding piece 110 and extends across the entire curved outer surface at the center of the width of the arm-shaped wall portion. The dividing wall 115 is a wall portion that rises perpendicular to the bottom surface of the first holding piece 110, and its linearly rising edge forms a second side portion 111b. The dividing wall 115 is formed between the two rows of first locking teeth 113 and is arranged to divide the first locking teeth 113 into two in the width direction. This dividing wall 115 functions as a restricting portion that restricts widthwise displacement of the second holding piece 120, which will be described later. A tapered guide edge 115a is formed at the tip end of the dividing wall 115. The guide edge 115a functions to guide the partition wall 115 as it enters a partition groove 125 of the second holding piece 120, which will be described later.

[0039] 3(a) and 6, both side surfaces of the dividing wall 115 are spaced apart from the two rows of first locking teeth 113, with grooves 116 provided between them. The grooves 116 are regions recessed relative to the first locking teeth 113, and are elongated passages formed on the sides of each first locking teeth 113, extending in the circumferential direction over almost the entire arm-shaped wall portion. As will be described later, the grooves 116 function as guide passages that guide the progress of the second holding pieces 120 in the overlapping direction, or as receiving recesses that receive the protruding grooves 124 of the second holding pieces 120.

[0040] 3(a) and 6, the circumferential tip end portion of each groove portion 116 (the end portion facing the tip portion of the second holding piece 120) is closed by a blocking wall portion 114. The blocking wall portion 114 is a wall portion formed beside the tip-most locking tooth of the first locking tooth row 113. Each blocking wall portion 114 is formed integrally 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 part of an engagement preventing means that prevents the locking teeth of the first locking tooth row 113 from engaging with the locking teeth of the second locking tooth row 123 in a number of sets less than the specific number N (=3).

[0041] 7, an engaging portion 118 and an engaged portion 119 serving as a connecting mechanism are provided on a first side portion 111a and a second side portion 111b of a base portion 111 of the first holding piece 110. In this embodiment, the engaging portion 118 and the engaged portion 119 are provided near the bottom of the first holding piece 110.

[0042] The engaging portion 118 is formed to protrude from the first side portion 111a in the arrangement direction of the wiring / piping material holder 100. The engaging portion 118 has a base end 118a integrally connected to the outer wall (first side portion 111a) of the first holding piece 110, and a main body portion 118b that is semicircular in front view, extends from the base end 118a toward the bottom, and protrudes outward in the arrangement direction. The main body portion 118b is formed with an engaging groove 118c that is T-shaped in plan view, penetrates vertically, and is open to the outside. A cavity into which the main body portion 118b can retract is formed on the inside of the engaging portion 118 of the first holding piece 110 in the arrangement direction. The engaging portion 118 can be displaced in the arrangement direction by rotating about the base end 118a, and can be displaced to change the amount of protrusion in the arrangement direction.

[0043] On the other hand, the engaged portion 119 is formed on the second side portion 111b in the arrangement direction of the wiring / piping material holder 100 so as to be able to engage with the engaging portion 118. The engaged portion 119 is provided on the edge of the dividing wall 115 in the arrangement direction, and is formed to protrude in the width direction from both side surfaces of the dividing wall 115. That is, the engaged portion 119 is made of a T-shaped connecting piece that can cooperate with the dividing wall 115 to fit into the T-shaped engaging groove 118c. Furthermore, the engaged portion (connecting piece) 119 is arranged so as to be separated from the first locking tooth row 113 across the dividing wall 115. This prevents the tip portion of the second holding piece 120 from interfering with the engaged portion 119 during the locking operation.

[0044] The engaging portion 118 and the engaged portion 119 are configured to be able to engage with and disengage from each other by sliding relative to each other in the erection direction (direction perpendicular to the bottom surface) (see FIG. 24). Adjacent wiring and piping material holders 100 are connected together in the lining direction by engagement of the engaging portion 118 of one wiring and piping material holder 100 with the engaged portion 119 of another wiring and piping material holder 100 (see FIG. 23). As shown in FIGS. 5 and 13, the engaging portion 118 can be displaced, as necessary, from a first position where it can be connected to the engaged portion 119 of another wiring and piping material holder 100 to a second position where it does not protrude beyond the outer surface (first side portion 111a) of the base 111 and where it cannot be connected to the engaged portion 119 of another wiring and piping material holder 100.

[0045] The second holding piece 120 is a band extending in an arch shape from the base end to the tip end. The second holding piece 120 has a base end portion curved in an arc shape and a tip end portion connected to the base end portion that is more gently curved. A thin hinge 130 is connected to 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 so that it overlaps the tip end portion of the first holding piece 110.

[0046] The tip portion of the second holding piece 120 is provided with separation pieces 121 separated in the width direction within a predetermined length range from the circumferential tip. The two separation pieces 121 have free ends independent of each other. One of the two separation pieces 121 and the other separation piece can be elastically deformed inward and outward in the radial direction, independently of each other, around their base ends. The two separation pieces 121 are formed side by side in the width direction perpendicular to the extension direction of the second holding piece 120, and are separated in the width direction by a dividing groove 125 of a predetermined width. This dividing groove 125 has a width that allows the dividing wall 115 of the first holding piece 110 to be inserted therethrough.

[0047] The second holding piece 120 has a second holding portion 122 that forms an arc-shaped recess on its inner surface for holding the wiring / piping material P, and a second locking portion (second locking tooth row 123) for maintaining the holding space 101 surrounding the wiring / piping material P.

[0048] The second gripping portion 122 has an arc-shaped recess along the extension direction from the base end to the tip end of the second holding piece 120 so as to grip the wiring / piping material P. The second gripping portion 122 is formed as a curved surface that is approximately arc-shaped in cross section 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 match the circumference of the corresponding maximum diameter (i.e., the outer peripheral shape of the wiring / piping material PL). In other words, the curvature of the second arc portion corresponds to the corresponding maximum diameter circle. In addition, the second arc portion has an arc-plate-shaped rib 122a that fits into the valley portion of the wiring / piping material P, which is a corrugated flexible tube, and engages the wiring / piping material P in the longitudinal direction.

[0049] On the inner surface of the tip portion of the second holding piece 120, a second locking tooth row 123 consisting of a plurality of (here, three) locking teeth formed consecutively in the direction of stacking is formed as a second locking portion. The second locking portion is provided on each of the two separation pieces 121. That is, the two rows of second locking tooth rows 123 are aligned in the circumferential direction and provided spaced apart on both sides of the second holding piece 120 in the width direction. These two rows of second locking tooth rows 123 are respectively arranged in widthwise positions so as to face the two rows of first locking tooth rows 113 in the radial direction. Furthermore, each second locking tooth row 123 is formed on the tip of each separation piece 121 and consists of three locking teeth. Each locking tooth constituting the second locking tooth row 123 has a sawtooth shape with an inclined surface on the tip side and an locking surface on the opposite side that stands approximately vertically from the inner surface of the separation piece 121. When the distal end portions of the first retaining piece 110 and the second retaining piece 120 overlap, the locking teeth of the first locking tooth row 113 and the second locking tooth row 123 click and engage with each other in the radial direction. At this time, the inclined surfaces of the locking teeth slide against each other, allowing relative movement in a direction that advances the overlap and reduces the retention space 101. As the overlap advances, when one locking tooth overcomes the opposing locking tooth by sliding their inclined surfaces against each other and then engages with the next locking tooth, the user can feel a clicking sensation and sound due to the engagement of the locking teeth. Meanwhile, the locking surfaces of the locking teeth engage with each other, restricting relative movement in a direction that retracts the overlap and expands the retention space 101. Furthermore, the second locking tooth row 123 displaces radially outward relative to the first locking tooth row 113, releasing the engagement state between the two locking teeth.

[0050] 1(b), 4, and 6, a protruding ridge 124 is formed on the inner side of the second locking tooth row 123 in the width direction, as a blocking ridge (part of the engagement blocking means) or a guide ridge. The protruding ridge 124 extends along the arrangement from the first locking tooth at the tip side of the second locking tooth row 123 to the third locking tooth. In other words, the protruding ridge 124 has a length that spans all of the locking teeth in the second locking tooth row 123. The protruding ridge 124 protrudes from the inner surface of the inner edge of each separation piece 121 in the width direction, and is formed integrally with the inner side of three (a specific number N) locking teeth in the width direction. The ridge portion 124 cooperates with the blocking wall portion 114 as part of the engagement blocking means to function as a blocking protrusion that prevents the locking teeth of the first locking tooth row 113 and the locking teeth of the second locking tooth row 123, which are radially opposed to each other, from engaging with each other in a number of pairs less than the specific number N (=3). The shape of the ridge portion 124 may be modified as needed. For example, if the specific number N is 2, the ridge portion 124 may be formed to extend along the arrangement from the first locking tooth on the tip side of the second locking tooth row 123 to the second locking tooth. Alternatively, if the specific number N is greater than 3, the ridge portion 124 may be formed to extend along the arrangement from the first locking tooth on the tip side of the second locking tooth row 123 to the Nth (>3) locking tooth. The number of teeth constituting the second locking tooth row 123 may be greater than the specific number N.

[0051] Each ridge 124 is formed at the same widthwise position as each blocking wall 114 provided at the tip of the first holding piece 110. The ridge 124 is configured to abut against the blocking wall 114 from the radial direction when the tip portions of the first holding piece 110 and the second holding piece 120 begin to overlap. The tip edge of the ridge 124 is chamfered in a tapered shape so that when it abuts against the tip edge of the blocking wall 114, the second holding piece 120 is guided radially outward from the first holding piece 110. Furthermore, the ridge 124 preferably has a protruding height equal to or greater than the protruding height of the locking teeth to prevent the locking teeth from getting caught on each other. Here, the protruding height of the ridge 124 and the protruding height of the locking teeth are approximately the same. Furthermore, the protruding ridge 124 is configured to be received in a recessed ridge 116 formed on the side of the blocking wall 114 of the first locking tooth row 113 of the first holding piece 110 in the direction of travel (or beyond the blocking wall 114 in the direction of travel). As a result, when the overlap between the first holding piece 110 and the second holding piece 120 progresses to a position where the blocking wall 114 and the protruding ridge 124 do not overlap, the recessed ridge 116 is accommodated in the protruding ridge 124 as a receiving recess, allowing the locking teeth of the first locking tooth row 113 to engage with the locking teeth of the second locking tooth row 123. The series of operations performed by the engagement prevention means will be described in more detail later with reference to FIG. 17. Furthermore, the protruding ridge 124, as a guide protrusion, is slidable while being guided by the recessed ridge 116, which serves as a guide passage. By maintaining the ridges 124 within the grooves 116, the separation pieces 121 are prevented from shifting in the width direction during the operation of advancing the overlapping.

[0052] 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 portion 128 protrudes on both sides of the second holding piece 120 in the installation direction. The release operation portion 128 is configured so that when the user operates the release operation portion 128 to lift it outward (radially) of the holding space 101 using a finger or a shaft-shaped operating tool T (see FIGS. 18 and 19), the second locking portion is separated from the first locking portion in the radial direction of the wiring / piping material P, thereby releasing the lock of the first locking portion and the second locking portion. In this embodiment, the release operation portion 128 is a rectangular knob, but its shape can be selected arbitrarily. The release operation portion 128 protrudes in the installation direction so as to face the outer circumferential surface of the wiring / piping material P to which it is being held via a gap. The gap is formed to a size that allows an operating tool T to be inserted between the outer peripheral surface of the wiring / piping material P held in the holding space 101 and the release operating part 128 (see FIG. 19(a)). In addition, since the two separation pieces 121 are elastically deformable independently of each other, operating one of the release operating parts 128 operates to release only one of the separation pieces 121 from the engagement.

[0053] The hinge 130 connects the base ends of the first holding piece 110 and the second holding piece 120 and is configured to rotate the first holding piece 110 and the second holding piece 120 in the opening and closing directions. The hinge 130 is a thin piece that is relatively thin compared to the first holding piece 110 and the second holding piece 120 and is elastically deformable preferentially compared to other parts. When the first holding piece 110 and the second holding piece 120 are displaced in a direction in which they overlap, the hinge 130 is bent and deformed at an acute angle. On the other hand, when the first holding piece 110 and the second holding piece 120 are displaced in a direction in which the opening portion 103 is enlarged, the hinge 130 is bent and deformed at an obtuse angle. Due to the bending of the hinge 130, a hinge-side space 105 is formed inside the hinge 130.

[0054] The auxiliary piece 140 is provided to prevent the wiring / piping material P held in the holding space 101 from escaping into the hinge-side space 105. The auxiliary piece 140 is an arc-shaped strip that rises from the inner surface of the first holding piece 110 with its tip as a free end and a protruding length toward the inner surface of the second holding piece 120. The auxiliary piece 140 is arranged so as to be positioned between the wiring / piping material P placed 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 closer to the hinge 130 than the center of the holding space 101 of the first holding piece 110. In this embodiment, the auxiliary piece 140 rises into the holding space 101 when holding the corresponding smallest diameter wiring / piping material PS. Furthermore, the auxiliary piece 140 is arranged so as to face the inner surface of the tip portion of the first holding piece 110. Furthermore, a space is formed on the hinge 130 side of the auxiliary piece 140 to allow the auxiliary piece 140 to tilt toward the hinge 130. This space is a retraction space for the inner surface of the auxiliary piece 140 (the side that abuts against the wiring / piping material P) to retract to a position where it joins 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 largest diameter wiring / piping material PL.

[0055] The auxiliary piece 140 includes a base end 141 that is elastically deformable at its base end, and an abutment portion 142 that can abut against the outer circumferential surface of the wiring / piping material P. The base end 141 is a relatively thin portion of the auxiliary piece 140 and assists the elastic tilting of the auxiliary piece 140. The abutment portion 142 has an arc-shaped curved surface facing the tip side of the first holding piece 110 to abut against the outer circumferential surface of the wiring / piping material P. The curved surface of the abutment portion 142 is determined to match the circumference of the corresponding maximum diameter (i.e., the outer circumferential shape of the wiring / piping material PL). In other words, the curvature of the curved surface of the abutment portion 142 corresponds to the circle of the corresponding maximum diameter. The abutment portion 142 also has an arc-shaped plate-like rib 142a that fits into the valley portion of the wiring / piping material P, which is a corrugated flexible tube, and engages in the longitudinal direction. That is, the first arcuate portion, the second arcuate portion, and the curved surface of the abutting portion 142 have the same curvature and are configured to be able to be positioned on the same circumference as the diameter of the wiring / piping material PL.

[0056] Furthermore, the auxiliary piece 140 is positioned closer to the tip of the first holding piece 110 than the holding position of the wiring / piping material P so that when gripping a wiring / piping material P of a predetermined diameter (including a wiring / piping material PS of the corresponding minimum diameter), the auxiliary piece 140 abuts against the outer peripheral surface of the wiring / piping material P and tilts toward the hinge 130. As shown by the imaginary line in FIG. 4, the abutting portion 142 is elastically displaceable so as to tilt from the initial position toward the hinge 130 around the base end portion 141. When placing a wiring / piping material P of a size ranging from the corresponding minimum diameter to the maximum diameter in the holding space 101, the auxiliary piece 140 elastically tilts toward the hinge 130 as the wiring / piping material P is tightened, and the auxiliary piece 140 is pressed against the wiring / piping material P by its resilient force. On the other hand, when introducing wiring / piping material PL of the corresponding maximum diameter into the holding space 101, the auxiliary piece 140 can also act to temporarily hold the wiring / piping material PL by clamping the wiring / piping material PL in cooperation with the inner surface of the tip portion of the first holding piece 110 that faces the inner surface of its abutment portion 142.

[0057] Furthermore, the auxiliary piece 140 is configured so that the tip of the auxiliary piece 140 abuts against the inner surface of the second holding piece 120 when the holding space 101 in which the wiring / piping material P is placed is reduced. For example, when holding a wiring / piping material PS with a corresponding smallest diameter, the auxiliary piece 140 is pressed toward the hinge 130 by the wiring / piping material PS, as shown by the imaginary line in FIG. 8, causing the auxiliary piece 140 to retract toward the hinge 130 and assume an upright position. When the auxiliary piece 140 is in the retracted position (the imaginary line in FIG. 8), it interferes with the inner surface of the second holding piece 120, and is therefore pressed from the hinge 130 side toward the tip of the second holding piece 120 by the inner surface of the second holding piece 120. This pressing force can also cause the auxiliary piece 140 to move from the retracted position toward the tip of the second holding piece 120. In this way, the position and protruding length of the auxiliary piece 140 are determined so that when a wiring / piping material P of a predetermined diameter is held in the holding space 101, the tip of the auxiliary piece 140, which has tilted to a retracted position according to the diameter of the wiring / piping material P, abuts or presses against the inner surface of the second holding piece 120 (or the inner surface of the second arc portion).

[0058] Next, with reference to Figs. 9 to 12, an installation structure 10 will be described in which wiring and piping material PS of the corresponding smallest diameter is held and arranged in a construction material 11 (structure) by the wiring and piping material holder 100 of this embodiment. 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 an E-E cross-sectional view of the installation structure 10. Fig. 12 is an F-F cross-sectional view of the installation structure 10.

[0059] 9 and 10, in the installation structure 10 of this embodiment, the structure is a columnar construction material 11 that stands upright, and a wiring / piping material holder 100 is fixed to the front side (installation surface) of the construction material 11. The wiring / piping material holder 100 grips the wiring / piping material PS, and the wiring / piping material is arranged so that it is arranged vertically.

[0060] As shown in Figure 12, in the installation structure 10, the fixing surface 111c of the base 111 of the wiring / piping material holder 100 abuts against the side surface of the construction material 11, and the screw 15 penetrates the insertion portion 111e, thereby fixing the wiring / piping material holder 100 to the construction material 11. At this time, the head of the screw 15 is received in the recess 111d of the base 111, and the shank is screwed into the construction material 11. The wiring / piping material holder 100 is fixed in an attitude in which its width direction is aligned vertically.

[0061] In the installation structure 10, wiring and piping material PS is held in a closed holding space 101 of a wiring and piping 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 engages 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 that holds wiring and piping material PS having a corresponding minimum diameter, the three locking teeth of the second locking tooth row 123 engage with the three locking teeth at the rearmost end of the first locking tooth row 113 so as to maximize the amount of overlap between the first holding piece 110 and the second holding piece 120. The locking surfaces of the first locking tooth row 113 and the second locking tooth row 123 are locked in the circumferential direction, thereby restricting relative movement of the second holding piece 120 with respect to the first holding piece 110 in a direction that would cause the overlap to retreat. As a result, the holding space 101 surrounding the wiring / piping material PS is kept at a minimum.

[0062] In the installation structure 10, as shown in Fig. 11, the arc-shaped portion of the first gripping portion 112, the arc-shaped portion of the second gripping portion 122, and the abutment portion 142 of the auxiliary piece 140 are each pressed against the outer peripheral surface (outer peripheral surface of the peak portion) of the wiring / piping material PS, thereby gripping the wiring / piping material PS. Also, as shown in Fig. 12, the ribs 112a, 122a, and 132a enter the valley portion of the wiring / piping material PS and are pressed against the outer peripheral surface of the valley portion. As a result, the wiring / piping material PS is stably gripped so as not to move freely within the holding space 101.

[0063] The auxiliary piece 140 is positioned between the outer peripheral surface of the wiring / piping material PS and the hinge 130. The auxiliary piece 140 blocks communication between the holding space 101 and the hinge-side space 105. Furthermore, the tip of the auxiliary piece 140 engages with the inner surface of the second gripping portion 122 of the second holding piece 120 in a position retracted from the original position toward the hinge 130. The auxiliary piece 140 is pressed by the inner surface of the second gripping portion 122 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). This pressing force further strengthens the grip of the wiring / piping material PS by the three points of the first holding piece 110, the second holding piece 120, and the auxiliary piece 140. Furthermore, because the auxiliary piece 140 supports the wiring / piping material PS from the hinge 130 side, it does not tilt further toward the hinge-side space 105. Therefore, the auxiliary piece 140 prevents the wiring / piping material PS from escaping from the holding space 101 into the hinge-side space 105. Furthermore, the auxiliary piece 140 is arranged to be stretched between the inner surface of the first holding piece 110 and the inner surface of the second holding piece 120. This moves the fulcrum of rotation of the second holding piece 120 relative to the first holding piece 110 from the hinge 130 to the tip of the auxiliary piece 140, preventing smooth rotation of the first holding piece 110 and the second holding piece 120 around the hinge 130 in a direction that moves the overlapping portion back. As a result, it is possible to more firmly maintain the locked state between the first locking portion and the second locking portion.

[0064] The locked state of the wiring / piping material holder 100 is achieved by the second locking tooth rows 123 formed on the two separation pieces 121 of the second holding piece 120 independently engaging with the two rows of first locking tooth rows 113. In other words, even if one separation piece 121 is unintentionally displaced radially outward, disengaging one set of the first locking tooth row 113 and the second locking tooth row 123, the engagement of the other set can be maintained. Furthermore, in the installation structure 10, the dividing wall 115 of the first holding piece 110 fits into the dividing groove 125 of the second holding piece 120, and the convex ridge portion 124 formed beside the second locking tooth row 123 is housed in the concave ridge portion 116, thereby restricting the first holding piece 110 and the second holding piece 120 from shifting in the arrangement direction (width direction) of the wiring / piping material PS. That is, in the installation structure 10, the wiring / piping material holder 100 maintains a firm grip on the wiring / piping material PS.

[0065] FIG. 13 shows an installation structure 10-1, which is a variation of the installation structure 10 of FIG. 12, in which a wall material 13 is further erected on the side surface of the construction material 11. In the installation structure 10 shown in FIG. 12, the outer surface of the first side portion 111a of the wiring / piping 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). In contrast, in the installation structure 10-1 shown in FIG. 13, the wall material 13 is erected, so that the wall surface of the wall material 13 abuts against the engaging portion 118, and the engaging portion 118 is displaced inward of the first side portion 111a. That is, the engaging portion 118 is displaced from a first position (see FIG. 12) where it can be connected to an engaged portion 119 of another wiring / piping material holder 100 to a second position (see FIG. 13) where it does not protrude beyond the outer surface of the first side portion 111a of the base 111. Therefore, in the installation structure 10-1, the wall material 13 is erected on the side of the construction material 11 without interfering with the wiring and piping material holder 100.

[0066] FIG. 14 shows an installation structure 10-2, which is a variation of the installation structure 10 of FIG. 11 , in which a wiring / piping material PL having the largest diameter among the corresponding wiring / piping materials P is arranged. In this installation structure 10-2, the wiring / piping material PL is held in a closed holding space 101 of a wiring / piping material holder 100. The tip portions of the first holding piece 110 and the second holding piece 120 overlap with each other, and the second locking tooth row 123 engages with the first locking tooth row 113 from the radially outer side, thereby maintaining the holding space 101 in a closed state. In the installation structure 10 that holds the wiring / piping material PL having the corresponding largest diameter, the three locking teeth of the second locking tooth row 123 engage with the three locking teeth closest to the tip of the first locking tooth row 113 so as to minimize the amount of overlap between the first holding piece 110 and the second holding piece 120. The locking surfaces of the first locking tooth row 113 and the second locking tooth row 123 are locked in the circumferential direction, thereby restricting the second holding piece 120 from moving relative to the first holding piece 110 in the direction in which the overlap retreats. As a result, the holding space 101 surrounding the wiring / piping material PL is maintained in its maximum size.

[0067] As shown in FIG. 14 , the arc-shaped portions of the first gripping portion 112, the second gripping portion 122, and the abutting portion 142 of the auxiliary piece 140 each abut against the outer circumferential surface (the outer circumferential surface of the peaks) of the wiring / piping material PL, thereby gripping the wiring / piping material PL. At this time, the first arc-shaped portion, the second arc-shaped portion, and the curved surface of the abutting portion 142 are located on the same circumference as the outer circumferential surface (of the peaks) of the wiring / piping material PL. Although not shown, the ribs 112a, 122a, and 132a enter the valleys of the wiring / piping material PL and abut against the outer circumferential surface of the valleys. Similarly, the inner circumferential edges of the ribs 112a, 122a, and 132a are located on the same circumference as the outer circumferential surface (of the valleys) of the wiring / piping material PL. Therefore, the wiring and piping material PL is stably held by the wiring and piping material holder 100 so that it does not move freely within the holding space 101. When holding a wiring and piping material PL having the maximum compatible diameter, the holding position of the wiring and piping material PL is determined to be one location within the holding space 101, and there is no need to check the position of the wiring and piping material PL or align the wiring and piping material PL.

[0068] Furthermore, the auxiliary piece 140 is positioned between the outer peripheral surface of the wiring / piping material PL and the hinge 130. The auxiliary piece 140 is tilted to a position close to the hinge 130. The auxiliary piece 140 blocks communication between the holding space 101 and the hinge-side space 105. Furthermore, the tip of the auxiliary piece 140 is in a position retracted from the original position toward the hinge 130 and abuts against the inner surface near the base end of the second holding piece 120. At this time, the second holding piece 120 does not urge the auxiliary piece 140 toward the center of the holding space 101. In other words, when holding the wiring / piping material PL with the largest diameter, the auxiliary piece 140 is retracted to a position where it is not pressed (or moved) toward the tip by the inner surface of the second holding piece 120.

[0069] Next, with reference to FIG. 15, a method for constructing an installation structure 10 in which wiring and piping material PS (with the corresponding smallest diameter) is arranged on construction material 11 using wiring and piping material holder 100 will be described.

[0070] As shown in Figure 15, wiring and piping material holder 100 is fixed at a predetermined fixing position on the installation surface of construction material 11. While facing fixing surface 111c of wiring and piping material holder 100 against the installation surface of construction material 11, wiring and piping material holder 100 is positioned, and while maintaining this posture to determine the installation direction of wiring and piping material P, screws 15 are inserted into insertion portions 111e from the front. Then, by operating a tool (a screwdriver) to screw screws 15 into construction material 11, wiring and piping material holder 100 can be fixed to construction material 11.

[0071] Next, with reference to FIG. 16, steps of a method for holding the wiring / piping material P with the wiring / piping material holder 100 will be illustrated.

[0072] First, the opening 103 of the wiring / piping holder 100 is opened, and the wiring / piping material P is inserted into the holding space 101 through the opening 103. As shown in FIG. 16( a), the wiring / piping material P is placed between the tip of the first holding piece 110 and the auxiliary piece 140. At this time, the wiring / piping material P is positioned closer to the tip than the center of the holding space 101 and is sandwiched between the abutment portion 142 of the auxiliary piece 140, which has been elastically displaced radially outward, and the inner surface of the first holding piece 110. Then, the second holding piece 120 is rotated about the hinge 130 in a direction to close the opening 103. The tip of the first holding piece 110 and the tip of the second holding piece 120 are brought into contact with each other, and the first locking tooth row 113 and the second locking tooth row 123 are engaged with each other. Here, the engagement prevention means prevents two or fewer of the second locking tooth row 123 from engaging with the locking teeth of the first locking tooth row 113, and only after the overlapping has progressed to a position where three sets of locking teeth face each other is the locking state formed by the first locking portion and the second locking portion (see Figure 17).

[0073] After the locking state is initially formed, as the overlapping of the first holding piece 110 and the second holding piece 120 progresses, the inner surface of the second holding piece 120 comes into contact with the outer peripheral surface of the wiring / piping material P, as shown in Figure 16(b). Then, as the tightening operation is continued to reduce the holding space 101, the wiring / piping material P is pushed toward the center of the holding space 101, and the auxiliary piece 140 tilts toward the hinge 130 and rises from its inclined position, as shown in Figure 16(c). The tip of the auxiliary piece 140 comes into contact with (or is close to) the inner surface of the second holding piece 120.

[0074] Furthermore, when the second holding piece 120 is tightened against the first holding piece 110, as shown in FIG. 16(d), the tip of the auxiliary piece 140 presses against the inner surface of the second holding piece 120, causing the auxiliary piece 140 to move toward the center of the holding space 101 and tilt slightly. In other words, as the holding space 101 is reduced in size, the tip of the auxiliary piece 140 slides along the inner surface of the second holding piece 120 and tilts toward the tip of the second holding piece 120. The auxiliary piece 140 then acts to bias or press the wiring / piping material P toward the center of the holding space 101. In this way, the gradual engagement of the first and second locking portions in the direction reducing the size of the holding space 101 increases the pressing force of the auxiliary piece 140. As a result, the wiring / piping material P can be firmly gripped by the wiring / piping material holder 100 and stably held in the holding space 101.

[0075] When installing wiring / piping material P of a different diameter, the engagement positions of the first locking tooth row 113 and the second locking tooth row 123 are shifted toward the front or rear end, but the basic process is the same. However, the operation of the auxiliary piece 140 changes depending on the diameter of the wiring / piping material P. For example, when holding wiring / piping material PL of the maximum compatible diameter, the auxiliary piece 140 is completely retracted toward the hinge 130, so it is not pressed toward the front end by the inner surface of the second holding piece 120 and is not moved toward the center of the holding space 101.

[0076] Next, the function of the engagement preventing means in the above-mentioned process will be described with reference to Figure 17. The engagement preventing means prevents less than a specific number N of locking teeth in the second locking tooth row 123 from engaging with the locking teeth of the first locking tooth row 113. The specific number N can be selected from integers equal to or greater than 2. In this embodiment, the specific number N is 3, which is the number of teeth in the second locking tooth row 123. In other words, engagement by only one or two sets of locking teeth is prevented.

[0077] 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.

[0078] 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 a 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. Thus, 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.

[0079] Subsequently, referring 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 for gripping the wiring and pipe material P will be described.

[0080] As shown in FIG. 18 , a user can use an operating tool T with a thin tip, such as a flathead screwdriver, to elastically displace the second holding piece 120 radially outward of the wiring / piping material P via the release operating portion 128 of the wiring / piping material holder 100, thereby releasing the locked state between the first locking tooth row 113 and the second locking tooth row 123. The operating tool T is operated in a direction perpendicular to the installation direction of the wiring / piping material P, from the space in front of the installation surface of the construction material 11. In other words, the user can operate the operating tool T using the larger space in front of the wiring / piping material P to more easily release the lock. In particular, because the release operating portion 128 protrudes from the side of the wiring / piping material P in the installation direction, forming a gap that opens in a direction different from the pipe axis (direction) of the wiring / piping material P, it is not necessary to perform the release operation while the operating tool T is aligned with the pipe axis (which would easily cause the handle of the operating tool to interfere with the outer surface of the wiring / piping material). 18, two separation pieces 121 are provided at the tip of the second holding piece 120, so that one separation piece 121 is displaced with each release operation, and only one of the separation pieces 121 is released from the locked state. At this time, the other separation piece 121 remains locked, so the release operation must be performed sequentially on the remaining separation pieces 121.

[0081] The release operation will be described in more detail with reference to FIG. 19 . First, the tip of the operating tool T is inserted into the gap between the outer circumferential surface of the wiring / piping material P and the release operating portion 128 extending opposite thereto. Next, as shown in FIG. 19( a), the operating tool T is brought into contact with two points: the outer circumferential surface of the wiring / piping material P and the release operating portion 128. The operating tool T is tilted in the circumferential direction of the wiring / piping material P, with the contact point with the outer circumferential surface of the wiring / piping material P as the fulcrum and the contact point with the release operating portion 128 as the point of application (see the arrow in FIG. 19( a)). Then, as shown in FIG. 19( b), the tip of the operating tool T can lift the release operating portion 128 radially outward from the wiring / piping material P, thereby separating the second locking tooth row 123 radially outward from the first locking tooth row 113. In this way, the locking state by the locking teeth of the first locking tooth row 113 and the second locking tooth row 123 is released. In this state, the operating tool T is pulled out from the gap, thereby completing the unlocking operation of one of the separation pieces 121.

[0082] Next, with reference to Figs. 20 to 23, an installation structure 10-3 of another form will be described in which one wiring and piping material holder 100 is installed on a structure while being connected to another adjacent wiring and piping material holder 100 via a connecting mechanism. The installation structure 10-3 has wiring and piping material holders 100 arranged side by side to align and arrange a plurality of wiring and piping 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 connecting mechanism of adjacent wiring and piping material holders 100.

[0083] As shown in Figures 20 to 22, in an installation structure 10-3, a plurality of wiring and piping material holders 100 are fixed in a line on the installation surface of a structure 11 and hold wiring and piping material P in a common installation direction. One wiring and piping material holder 100 is connected to the other wiring and piping material holders 100 by a connecting mechanism in a line-up direction that intersects with the installation direction of the wiring and piping material P. In addition, a wall material 13 is erected adjacent to the wiring and piping material holder 100 located at the extreme end. Here, the engaging portion 118 of the wiring and piping material holder 100 rotates inward of the first side portion 111a, so that the wiring and piping material holder 100 and the wall material 13 are arranged adjacent to each other.

[0084] 23(a) and 23(b), a coupled state is formed by fitting the engaged portion 119 of another adjacent wiring and piping material holder 100 into the engaging groove 118c of the engaging portion 118 of one wiring and piping material holder 100. In this coupled state, displacement of the engaging portion 118 of one wiring and piping material holder 100 is restricted by engagement with the engaged portion 119 of the other wiring and piping material holder 100. In particular, because the engaging groove 118c and the engaged portion 119 extend perpendicularly to the fixing surface 111c (or the installation surface of the structure) by a predetermined length, even if the other wiring and piping material holder 100 attempts to approach or move away from the first wiring and piping 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, when the first wiring and piping material holder 100 and the other wiring and piping material holder 100 are placed against the installation surface of a structure, displacement of the engaging portion 118 is restricted (regardless of whether they are fastened with the screws 15). In other words, even before the wiring and piping material holder 100 is fastened to the structure, it is easy to maintain the relative position of the first wiring and piping material holder 100 and the other wiring and piping material holder 100, and it becomes possible to fasten the first wiring and piping material holder 100 and the other wiring and piping material holder 100 to the structure in a combined state.

[0085] As shown in FIG. 24 , the step of connecting one wiring / piping material holder 100 and another wiring / piping material holder 100 in the juxtaposition direction is performed by relatively sliding the engaged portion 119 of the other wiring / piping material holder 100 toward the engaging portion 118 of the first wiring / piping material holder 100 in a direction different from the juxtaposition direction (here, a direction perpendicular to the fixing surface 111c). Specifically, the engaging portion 118 and the engaged portion 119 can be engaged by inserting the engaged portion 119 into an opening of the engaging groove 118c of the engaging portion 118 facing the opposite side of the fixing surface 111c (upward in FIG. 24 ). Conversely, although not shown, the engaging portion 118 and the engaged portion 119 can also be engaged by inserting the engaged portion 119 into an opening of the engaging groove 118c of the engaging portion 118 facing the fixing surface 111c (downward in FIG. 24 ). In other words, since the sliding direction of the wiring / piping material holder 100 to be connected is different from the arrangement direction, the engaging portion 118 is prevented from unexpectedly displacing in the arrangement direction and retracting inward during the connecting operation, thereby enabling a smooth connecting operation.

[0086] Furthermore, as shown in FIG. 25 , the wiring / piping material holder 100 of this embodiment may be used in combination with a base 150 interposed between the installation surface of a structure to which the wiring / piping material holder 100 is fixed and a fixing surface 111c. That is, the wiring / piping material holding device includes the wiring / piping material holder 100 and the base 150. The base 150 includes a bottom wall portion 151 attached to the fixing surface 111c of the base 111. The bottom wall portion 151 is formed with a through-hole (not shown) that communicates with the insertion portion 111e of the base 111 and through which the screw 15 passes. The base 150 also includes an abutment wall portion 152 that stands upright from the bottom wall portion 151, extends into the space inside the first side portion 111a of the base 111, and abuts against the main body portion 118b of the engagement portion 118 from the inside. The abutment wall 152 engages with the main body 118b from the inside, thereby restricting displacement of the engaging portion 118 in a direction that reduces the amount of protrusion. This allows the engaging portion 118 to be maintained in a first position where it can be connected to the engaged portion 119 of another wiring / piping material holder 100. In other words, when connecting another wiring / piping material holder 100 to the engaging portion 118 of the wiring / piping material holder 100, selectively attaching the pedestal 150 to the base 111 prevents the engaging portion 118 from unintentionally retracting. Therefore, the wiring / piping material holder further improves user operability and convenience according to the usage pattern.

[0087] The following describes the effects of the wiring / piping material holder 100 according to one embodiment of the present invention.

[0088] First, with the wiring and piping material holder 100 of this embodiment, the engaging portion 118 protruding from the first side portion 111a in the arrangement direction of the wiring and piping material holder 100 engages with the engaged portion 119 provided on the second side portion 111b in the arrangement direction of the wiring and piping material holder 100, thereby making it possible to connect one wiring and piping material holder 100 to another wiring and piping material holder 100 in an arrangement direction that intersects with the installation direction of the wiring and piping material P. Furthermore, the engaging portion 118 is displaceable to change the amount of protrusion in the arrangement direction. As a result, when another wiring and piping material holder 100 is not connected to the first side portion 111a of one wiring and piping material holder 100, the engaging portion 118 can be displaced to a state where the amount of protrusion is reduced to prevent the engaging portion 118 from interfering with a structure such as a wall (wall material 13), thereby reducing the space required to install the wiring and piping material holder 100. Therefore, the wiring / piping material holder 100 of this embodiment can be connected to other wiring / piping material holders 100, and also allows the wiring / piping material P to be arranged even in a narrower space.

[0089] Second, according to the wiring / piping material holder 100 of this embodiment, the second holding piece 120 is provided with a release operation portion 128 that protrudes in the installation direction so as to face the outer circumferential surface of the wiring / piping material P to be held, with a gap therebetween. That is, because the release operation portion 128 protrudes in the installation direction from the second holding piece 120, which extends in the circumferential direction of the wiring / piping material P, the gap between the release operation portion 128 and the outer circumferential surface of the wiring / piping material P is open at least in the circumferential direction of the wiring / piping material P. A user can use the gap to operate the release operation portion 128 with a finger or a shaft-shaped operating tool T or the like from a direction intersecting or perpendicular to the wiring / piping material P to lift the release operation portion 128 outward (radially outward) from the holding space 101, thereby separating the second locking tooth row 123 from the first locking tooth row 113 in the radial direction of the wiring / piping material P and thereby releasing the lock of the first locking portion and the second locking portion. At this time, there is sufficient space for the unlocking operation in the direction intersecting or perpendicular to the wiring / piping material P, so the unlocking operation can be performed without interference from the wiring / piping material P extending in the installation direction. Therefore, the wiring / piping material holder 100 of this embodiment makes the unlocking operation easier.

[0090] Third, with the wiring / piping material holder 100 of this embodiment, the tip of the first holding piece 110 overlaps with the tip of the second holding piece 120, forming an annular holding space 101 surrounding the wiring / piping material P. By increasing the amount of overlap and shrinking the holding space 101, it is possible to hold wiring / piping materials P (PS, PL) of different diameters. When the first holding piece 110 and the second holding piece 120 overlap to hold a wiring / piping 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 response to this, an auxiliary piece 140 is provided that rises from the inner surface of the first holding piece 110 into the holding space 101 with its tip as a free end. The auxiliary piece 140 is located between the wiring / piping material P placed in the holding space 101 and the hinge 130, and has an abutting portion 142 that can abut against the outer circumferential surface of the wiring / piping material P. The auxiliary piece 140 blocks communication between the holding space 101 and the hinge-side space 105 and abuts against the wiring / piping material P arranged in the holding space 101 from the hinge 130 side. This prevents the grasped wiring / piping material P from escaping from the holding space 101 to the hinge-side space 105. Furthermore, the auxiliary piece 140 is configured so that the tip of the auxiliary piece 140 abuts against the inner surface of the second holding piece 120 when the overlapping of the first holding piece 110 and the second holding piece 120 progresses to reduce the holding space 101 in order to hold the wiring / piping material P. The auxiliary piece 140 can bias and support the wiring / piping material P from the hinge-side space 105 in conjunction with the overlapping movement of the first holding piece 110 and the second holding piece 120. Therefore, the wire and pipe material holder 100 of this embodiment can more stably hold wire and pipe materials P (PS, PL) of different diameters.

[0091] Fourth, according to the wiring / piping material holder 100 of this embodiment, the tip portion of the first holding piece 110 and the tip portion of the second holding piece 120 overlap with each other, thereby forming an annular holding space 101 that surrounds the wiring / piping material P. In particular, as the second holding piece 120 is displaced from the outside of the holding space 101 to overlap with the first holding piece 110, an engaged state is formed and maintained between 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. In other words, the wiring / piping material P can be held by the first holding piece 110 and the second holding piece 120 through a simple and intuitive operation of overlapping the second holding piece 120 with the first holding piece 110 from the outside of the holding space 101. Meanwhile, the first locking portion and the second locking portion can be relatively easily released from their engagement by moving away from each other in a direction different from the engagement direction. In contrast, the wiring / piping material holder 100 of this embodiment has two separation pieces 121, 121 with independent free ends arranged side by side at the tip portion of the second holding piece 120, and each separation piece 121 is provided with a second locking tooth row 123, thereby preventing the first locking portion and the second locking portion from being easily and unintentionally released from engagement. That is, the second locking tooth row 123 of one separation piece 121 and the second locking tooth row 123 of the other separation piece 121 can independently form an engaged state with each opposing first locking tooth row 113 and can be separated from each first locking tooth row 113. That is, to release the holding of the wiring / piping material P, it is necessary to operate the two separation pieces 121, 121 so that each second locking portion is separated from the first locking portion. Even if a force in a direction that separates the first and second locking portions is suddenly applied to one of the two separation pieces 121, causing the locked state to be released, the locked state of the other separation piece 121 is maintained, preventing complete release of the hold on the wiring / piping material P. Since it is extremely rare for a force in a direction that separates the first and second locking portions to be suddenly applied to both of the two separation pieces 121, 121, the configuration of this embodiment effectively prevents the hold on the wiring / piping material P from being suddenly released.Therefore, the wiring / piping material holder 100 of this embodiment stably maintains the holding state of the wiring / piping material P and makes it possible to hold the wiring / piping material P with simpler operation.

[0092] Fifth, according to the wiring / piping material holder 100 of this embodiment, an engagement prevention means is provided that prevents the locking teeth of the first locking tooth row 113 from engaging with the locking teeth of the second locking tooth row 123 in a number of sets less than the specific number N (>1) (i.e., 1 to (N-1) sets) as the first holding piece 110 and the second holding piece 120 overlap. That is, as the number of sets of opposing locking teeth (at positions where they can engage) increases as the first holding piece 110 and the second holding piece 120 overlap, the engagement of the opposing locking teeth is prevented by the engagement prevention means before the number of opposing locking tooth sets reaches N. Then, as the overlap further progresses and the number of opposing locking tooth sets reaches the specific number N, the first engagement between the locking teeth of the first locking tooth row 113 and the locking teeth of the second locking tooth row 123 occurs, and the specific number N of sets of locking teeth simultaneously engage with each other. During the overlapping operation after this initial engagement position, the user can feel the touch and sound of the locking teeth engaging with each other. In other words, the engagement prevention means prevents the locking teeth from engaging with each other in fewer than N pairs. Therefore, during the tightening operation of the wiring / piping material P, which advances the overlapping of the first holding piece 110 and the second holding piece 120, the user is not misled into thinking that the tightening operation is complete when an insufficient number of pairs (less than the specific number N) are engaged. Therefore, the wiring / piping material holder 100 of this embodiment makes it possible to prevent the user from mistakenly determining that the tightening operation is complete.

[0093] [Variations] The present invention is not limited to the above-described embodiment, and various modifications are possible. Modifications of the present invention will be described below. In each modification, components designated by three digits that share the same last two digits have the same or similar characteristics unless otherwise specified, and their description will be omitted.

[0094] (1) The wiring and piping material holder of the present invention is not limited to the configuration of the above embodiment. The wiring and piping material holder of the present invention only needs to have at least a holding portion that holds the wiring and piping material along the installation direction and a connecting mechanism that connects one wiring and piping material holder to another adjacent wiring and piping material holder in an arrangement direction that intersects with the installation direction. For example, in the wiring and piping material holder of the present invention, the holding portion does not need to have a hinged pivot structure, and the open portion may be configured not to be closed.

[0095] For example, FIG. 26 shows a wiring / piping material holder 200 according to another embodiment. The wiring / piping material holder 200 has a coupling mechanism attached to both typical saddles. As shown in FIG. 26( a), the wiring / piping material holder 200 includes a U-shaped holding piece 210 having a holding space 201 formed therein as a holding portion, and a pair of bases 211 each having a fixing surface 211c formed on both sides of the holding piece 210. The wiring / piping material holder 200 also includes a coupling mechanism that couples one wiring / piping material holder 200 to another adjacent wiring / piping material holder 200 in an arrangement direction that intersects with the installation direction. An engaging portion 218 protrudes from a first side portion 211a of one base portion 211 in the arrangement direction, and an engaged portion 219 is formed on a second side portion 211b of the other base portion 211 in the arrangement direction. The engaging portion 218 of one wiring / piping material holder 200 and the engaged portion 219 of the other wiring / piping material holder 200 are configured to be able to engage with each other (see FIG. 26(b)). The engaging portion 218 can be displaced by tilting inward to change the amount of protrusion in the arrangement direction (see FIG. 26(c)).

[0096] (2) The connecting mechanism of the wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. The engaging portion of the present invention may be joined to the first side portion by a fragile portion, and may be displaceable so as to change the amount of protrusion in the arrangement direction by being removed by breaking the fragile portion as needed.

[0097] (3) The connecting mechanism of the wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. The engaging portion of the present invention may be attached to the first side portion by any connecting means (adhesion, fitting, magnetic attachment, etc.) and may be displaceable so as to change the amount of protrusion in the arrangement direction by being detached from the first side portion as needed.

[0098] (4) The connecting mechanism of the wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. In the above embodiment, the connecting mechanism is configured to restrict displacement of the engaging portion by connecting the engaging portion and the engaged portion when the fixing surface is placed against the installation surface. However, the connecting mechanism may be configured to allow the wiring / piping material holders to move relative to each other while still connected when the wiring / piping material holders are connected to each other while suspended in air.

[0099] (5) The wiring and piping material holder of the present invention is not limited to the configuration of the above embodiment. In the wiring and piping material holder of the above embodiment, the first holding piece, the second holding piece, and the hinge are integrally formed, but they may also be combined as separate pieces. The rigid first holding piece and second holding piece may be connected by an axial hinge, and the first holding piece and second holding piece may rotate around the hinge.

[0100] (6) The wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. In the wiring / piping material holder of the above embodiment, the first locking tooth row (first locking portion) has a large number of locking teeth, and the second locking tooth row (second locking portion) has three locking teeth. Since all of the locking teeth of the second locking tooth row simultaneously engage with the locking teeth of the first locking tooth row, the locking position changes depending on the amount of overlap between the first and second retaining pieces, but the amount of engagement (number of engagements) between the first and second locking portions remains constant. However, the present invention is not limited to this. That is, in the present invention, the second locking tooth row may be configured with a large number of teeth so as to be formed over the entire overlapping portion of the second retaining piece. In this configuration, the amount of engagement between the first and second locking portions can increase as the amount of overlap between the first and second retaining pieces increases.

[0101] The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various forms within the technical scope of the present invention. That is, within the technical scope of the present invention, some of the configurations of the present embodiments may be omitted or modified, or other configurations may be added.
