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 wiring and piping material fastener for gripping and fixing wiring and piping material to a structure such as a wall. In the following paragraphs, the reference numerals of Patent Document 1 are shown in parentheses. The wiring and piping material holder (100) includes a first holding piece (110) and a second holding piece (120) connected to the first holding piece (110) so as to surround the wiring and piping material (P) and hold it aligned in the installation direction. The second holding piece (120) overlaps with the first holding piece (110) from outside the holding space (101). The outer surface of the first holding piece (110) and the inner surface of the second holding piece (120) are provided with a first locking tooth row (113) and a second locking tooth row (123), which lock the first holding piece (110) and the second holding piece (120) together to maintain their overlap. The first locking tooth row (113) and the second locking tooth row (123) allow relative movement in the forward direction between the first holding piece (110) and the second holding piece (120), which increases the amount of overlap, and restrict relative movement in the backward direction, which decreases the amount of overlap. The second locking tooth row (123) is configured so that the locked state is released when the second locking tooth row (123) moves relative to the first locking tooth row (123) outward from the holding space (101). 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) it holds, with a gap between them. In the release operation step, the tip (or fingertip) of the operating tool (T) is inserted into the gap between the outer circumferential surface of the wiring / piping material (P) and the release operation portion (128) that extends opposite it. Next, the operating tool (T) is brought into contact with two points: the outer peripheral surface of the wiring / piping material (P) and the release operation portion (128). The operating tool (T) is tilted in the circumferential direction of the wiring / piping material (P), with the point of contact with the outer peripheral surface of the wiring / piping material (P) as the fulcrum and the point of contact with the release operation portion (128) as the point of application. This causes the tip of the operating tool (T) to lift the release operation 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 of the gap to complete the unlocking operation. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-53584 Summary of the Invention [Problem to be solved by the invention]

[0005] The wiring and piping holder of Patent Document 1 has a release operating portion that protrudes in the direction of the wiring and piping material arrangement so as to face the outer peripheral surface of the held wiring and piping material with a gap between them, thereby facilitating the release operation without interference from the wiring and piping material. However, in the conventional wiring and piping holder (Patent Document 1), when releasing the locked state of the first and second locking tooth rows, when deforming the distal end of the outer second retaining piece radially outward to separate it from the distal end of the first retaining piece, a relatively small amount of operation is required to separate the distal locking tooth of the second locking tooth row from the teeth of the first locking tooth row, while a relatively large amount of operation is required to separate the proximal locking tooth from the teeth of the first locking tooth row. As a result, after releasing the distal locking tooth of the second locking tooth row, the user is required to deform the second retaining piece radially outward, resulting in a problem of reduced operability. That is, in conventional wiring and piping material holders, the improvement of operability in releasing the lock is an issue to be addressed.

[0006] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a holder for wiring and piping material with improved operability in the unlocking operation. [Means for solving the problem]

[0007] A wiring / piping material holder according to one embodiment of the present invention is a wiring / piping material holder for holding wiring / piping material, comprising: a first holding piece extending from a base end to a tip end; a second holding piece connected to the first holding piece, extending from the base end to the tip end and cooperating with the first holding piece to surround the wiring / piping material and hold it along the installation direction; A tip portion of the first holding piece and a tip portion of the second holding piece overlap to form an annular holding space surrounding the wiring / piping material, and the second holding piece overlaps with the first holding piece from outside the holding space, a first locking portion and a second locking portion are provided on an outer surface of the first holding piece and an inner surface of the second holding piece, respectively, and the first holding piece and the second holding piece are locked to each other so as to maintain the overlapping of the first holding piece and the second holding piece; the first locking portion and the second locking portion are configured to allow relative movement in a forward direction that increases the amount of overlap between the first holding piece and the second holding piece, and to restrict relative movement in a backward direction that decreases the amount of overlap, and to release the locked state by the second locking portion moving relatively to the outside of the holding space with respect to the first locking portion, the first locking portion comprises a first locking tooth row consisting of a plurality of locking teeth formed in the direction of progression of the polymerization, and the second locking portion comprises a second locking tooth row consisting of a plurality of locking teeth formed in the direction of progression of the polymerization, and as the amount of polymerization increases, the locking teeth that engage with each other are switched, The second locking tooth row is composed of one or more base-end locking teeth located on the base-end side of the second retaining piece and one or more tip-end locking teeth located on the tip-end side of the second retaining piece, and is characterized in that the engagement depth when one locking tooth of the first locking tooth row engages with the base-end locking tooth is smaller than the engagement depth when one locking tooth of the first locking tooth row engages with the tip-end locking tooth. [Effects of the Invention]

[0008] According to one embodiment of the wiring / piping material holder of the present invention, the depth of engagement (in a direction perpendicular to the direction of overlap) between one locking tooth of the first locking tooth row and the proximal locking tooth of the second locking tooth row is smaller than the depth of engagement between one (identical) locking tooth of the first locking tooth row and the distal locking tooth of the second locking tooth row. This effectively reduces the amount of manipulation required to separate the proximal locking tooth from the first locking tooth when the second locking portion is operated to move relatively outward from the retaining space, thereby shortening the timing (point of manipulation) for completing the disengagement of the distal locking tooth and the proximal locking tooth. In other words, in the disengagement operation, in addition to the amount of manipulation of the distal portion of the second retaining piece to separate the distal locking tooth from the first locking tooth, the additional amount of manipulation required to further deform the distal portion of the second retaining piece outward can be effectively reduced or eliminated. Therefore, the wiring / piping material holder of the present invention facilitates the disengagement operation and improves its operability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] 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.

[0011] 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 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.

[0012] 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.

[0013] 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 an open holding space 101. 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.

[0014] 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.

[0015] 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, an auxiliary piece 140 rising from the inner surface of the first holding piece 110 with its tip as a free end, and a clamped piece 150 extending from the inner surface of the second holding piece 120 from the base end side toward the tip side of the second holding piece 120 into the holding space 101 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, the auxiliary piece 140, and the clamped piece 150 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 111a) of the wiring / piping material holder 100, is referred to as the erection direction.

[0016] 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 is formed between the tip of the first holding piece 110 and the tip of the second holding piece 120 for introducing the wiring / piping material P. 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. When the first holding piece 110 and the second holding piece 120 rotate or displace relatively around the hinge 130, the tip of the first holding piece 110 overlaps with the tip of the second holding piece 120, forming an annular holding space 101 that circumferentially surrounds the wiring / piping material P. At this time, the second holding piece 120 overlaps with the first holding piece 110 from the outside (radially outside) of the holding space 101. This closed holding space 101 can be maintained by the engagement of the first locking portion (first locking tooth row 113) of the first holding piece 110 and the second locking portion (second locking tooth row 123) of the second holding piece 120. The first locking portion and the second locking portion are released from the engagement by moving away from each other in a direction different from the locking direction (i.e., in the radial direction).

[0017] 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 overlapping amount between the first holding piece 110 and the second holding piece 120 increases, the locking amount between the first and second locking portions increases, or the relative locking positions of the first and second locking portions change. FIG. 8 is a schematic cross-sectional view of the wiring / piping material holder 100 in which the overlapping of the first and second holding pieces 110 and 120 is fully advanced, resulting in the smallest possible size of the holding space 101 (small diameter holding space). On the other hand, FIG. 9 is a schematic cross-sectional view of the wiring / piping material holder 100 in which the overlapping of the first and second holding pieces 110 and 120 is not advanced, resulting in the holding space 101 being relatively enlarged (large diameter holding space).

[0018] Each component of the wiring / piping material holder 100 of this embodiment will be described in detail below.

[0019] 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.

[0020] As shown in FIG. 5, the base 111 extends in the extension direction of the first holding piece 110 and has a first side portion on the right side in the extension direction when viewed from the front and a second side portion on the left side in the extension direction when viewed from the front. Here, the first side portion and the second side portion are both edges (excluding movable portions) of the first holding piece 110 when viewed from the front. A flat fixing surface 111a is defined on the bottom surface of the base 111. As shown in FIG. 5, a recess 111b 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 111c is formed at the bottom of the recess 111b, which penetrates the base 111 vertically and through which the shank of the screw 15 is inserted when fixing to a structure.

[0021] 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-like rib 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.

[0022] The arc-shaped outer surface of the arm-shaped wall portion of the first holding piece 110 is formed with a first locking tooth row 113, which is made up of a plurality of locking teeth arranged consecutively in the direction of stacking. In this embodiment, two rows of the first locking tooth row 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 portion. Each locking tooth constituting 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 portion on the opposite side (see FIG. 10 ). The teeth allow movement in only one direction relative to the substantially sawtooth-shaped locking teeth of the second locking tooth row 123 (described later) and act to lock in the other direction. Here, the first locking tooth row 113 has a greater number of locking teeth than the second locking tooth row 123. The greater the number of locking teeth that make up the first locking tooth row 113, the more the engagement between the first holding piece 110 and the second holding piece 120 can be maintained with the holding space 101 reduced. In other words, the maximum overlap amount between the first locking tooth row 113 and the second locking tooth row 123 is determined by the number of locking teeth in the first locking tooth row 113 or the second locking tooth row 123, whichever has the greater number of locking teeth. It is also preferable that the locking teeth in the first locking tooth row 113 have the same shape.

[0023] 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 perpendicularly to the bottom surface of the first holding piece 110, and its linearly rising edge forms a second side portion. 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 guide protrusion is formed on the tip of the dividing wall 115. The guide protrusion functions to guide the dividing wall 115 into a dividing groove 125 of the second holding piece 120, which will be described later.

[0024] 3(b) 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 beside 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.

[0025] 2, 3(b), 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 two locking teeth at the tip end side 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 teeth, and has the same cross-sectional shape as the locking teeth.

[0026] 7, an engaging portion 118 and an engaged portion 119 are provided as a connecting mechanism on a first side portion and a second side portion of the base 111 of the first holding piece 110, respectively. In this embodiment, the engaging portion 118 and the engaged portion 119 are provided near the bottom of the first holding piece 110. This connecting mechanism (the engaging portion 118 and the engaged portion 119) connects one wiring / piping material holder 100 to another wiring / piping material holder 100 adjacent to the one wiring / piping material holder 100 in an arrangement direction that intersects with the installation direction.

[0027] 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.

[0028] 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.

[0029] The second holding piece 120 has a second gripping portion 122 that forms an arc-shaped recess on its inner surface for gripping the wiring / piping material P, and a second locking portion (second locking tooth row 123) for maintaining the surrounding of the wiring / piping material P by the holding space 101. In addition, a deformation starting point 126 is formed in a bent portion of the second holding piece 120 that is closer to the base end than the second locking portion, and serves as a starting point (rotation center) when the tip portion of the second holding piece 120 rotates radially outward.

[0030] 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-shaped plate-shaped rib 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.

[0031] 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 locking teeth formed consecutively in the direction of polymerization 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 at widthwise positions that can face the two rows of first locking tooth rows 113 in the radial direction. Furthermore, each second locking tooth row 123 is made up of a plurality of locking teeth (base end side locking teeth 123a, tip end side locking teeth 123b) formed on the tip side of each separation piece 121. The second locking tooth row 123 is composed of a first locking tooth group consisting of multiple base-side locking teeth 123a and a second locking tooth group consisting of multiple distal-side locking teeth 123b (see FIG. 10). Each locking tooth constituting the second locking tooth row 123 has a generally sawtooth shape with a sloped surface on the distal end side and a locking surface on the opposite side that stands substantially perpendicular to the inner surface of the separation piece 121. When the distal ends of the first holding piece 110 and the second holding 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 sloped surfaces of the locking teeth slide against each other, allowing relative movement in a direction that advances the overlap and reduces the holding space 101. In other words, as the amount of overlap increases, the engaging teeth are swapped. As the overlapping progresses, when one locking tooth overcomes the other 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 hear the locking teeth engaging with each other. Meanwhile, the locking surfaces of the locking teeth are locked together, restricting relative movement in a direction that would retract the overlapping and expand the holding space 101. Furthermore, the second locking tooth row 123 is displaced radially outward relative to the first locking tooth row 113, thereby releasing the locked state of both locking teeth.

[0032] As shown in FIGS. 1(b) and 4, a convex ridge 124 is formed on the side of the second locking tooth row 123 on the inner side in the width direction. The convex ridge 124 extends along the arrangement from the first locking tooth at the tip side of the second locking tooth row 123 to the fifth locking tooth. The convex ridge 124 protrudes from the inner surface of the widthwise inner edge of each separation piece 121 and is integrally formed on the inner side of the widthwise inner portion of the five locking teeth. The convex ridge 124 cooperates with the blocking wall 114 to prevent 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 meshing in a number of pairs less than a specific number N (= 5).

[0033] 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 overlapping of 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. Furthermore, the protruding ridge 124 serves as a guide protrusion and is slidable while being guided by the recessed ridge 116 as a guide passage. By maintaining the protruding ridge 124 within the recessed ridge 116, the separation pieces 121 are prevented from shifting in the width direction during the operation of advancing the overlapping.

[0034] 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. In other words, 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 Figures 21 and 22), 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. 22(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.

[0035] 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 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 is formed inside it.

[0036] 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. 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 protrudes 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.

[0037] 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 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 approximately 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.

[0038] 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. 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 spring force presses against the wiring / piping material P. 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.

[0039] The clamped piece 150 extends from the inner surface of the second holding piece 120 from the base end side toward the tip end side of the second holding piece 120 with its tip end as a free end, and is configured to be clamped between the wiring / piping material P placed in the holding space 101 and the first holding piece 110 or the second holding piece 120. The clamped piece 150 extends a predetermined length in the circumferential direction so that its outer surface is spaced apart from the inner surface of the second holding piece 120 and faces the inner surface of the second holding piece 120. The clamped piece 150 has a thin plate-like base end portion 151 that is flexible and deformable on the base end side, an arc-shaped extension portion 152 extending from the base end portion 151, and a clamped portion 153 that expands inward and outward (radially) of the holding space 101 on the tip side of the extension portion 152 and has a tapered tip. The clamped pieces 150 can be displaced so as to tilt or rotate radially outward due to the flexural deformation of the base end portions 151 .

[0040] The clamped piece 150 has an arc-shaped inner surface from the base end to the tip end that faces the center of the holding space 101. The inner surface of the clamped piece 150 is determined so as to substantially match the circumference of the corresponding maximum diameter (i.e., the outer peripheral shape of the wiring / piping material PL).

[0041] The clamped portion 153 is formed so as to protrude from the outer surface of the extending portion 152, which extends with a substantially uniform thickness, toward the outside (radially outward) of the holding space 101. The clamped portion 153 gradually becomes thicker from its base end toward the center, with the thickest portion at the approximately central portion and gradually becoming thinner from there toward the tip. Furthermore, the clamped portion 153 has an arc-shaped outer surface facing radially outward in the tip-side portion where the thickness changes to be thinner. The outer surface of the tip-side portion of the clamped portion 153 is an arc-shaped surface with a curvature similar to or similar to that of the first arc-shaped portion so that the clamped portion 153 can slide circumferentially on the first arc-shaped portion.

[0042] 8, when the overlapping of first holding piece 110 and second holding piece 120 is completed and holding space 101 is reduced as much as possible, the outer surface of clamped portion 153 is displaced so as to be pressed against the first arc portion. At this time, clamped portion 153 of clamped piece 150 is positioned so as to face contact portion 142 of auxiliary piece 140 across the center of holding space 101. Clamped portion 153 functions to effectively fill the excess space between the inner surface of first holding piece 110 and the inner surface of auxiliary piece 140 (i.e., the space near the tip of first holding piece 110). Furthermore, clamped piece 150 is configured so that as the overlap between first holding piece 110 and second holding piece 120 progresses and the overlap between clamped portion 153 and first holding piece 110 increases, the tip of clamped piece 150 slides on the inner surface of first holding piece 110, gradually reducing the space (face-to-face distance) between auxiliary piece 140 and clamped portion 153. At this time, the tip of clamped piece 150 is pressed against the inner surface of first holding piece 110, causing bending deformation so that clamped portion 153 moves away from the inner surface of second holding piece 120.

[0043] Next, the configurations of the first locking tooth row 113 and the second locking tooth row 123 of the wiring / piping material holder 100 of this embodiment will be described in detail with reference to FIGS.

[0044] As shown in FIG. 10 , the second locking tooth row 123 is composed of a plurality of (six in this embodiment) base-end locking teeth 123a located on the base-end side of the second holding piece 120 and a plurality of (seven in this embodiment) tip-end locking teeth 123b located on the tip-end side of the second holding piece 120. In this embodiment, a group of locking teeth consisting of six locking teeth from the base-end side is formed as the base-end locking teeth 123a, and the remaining group of locking teeth is formed as the tip-end locking teeth 123b. In this embodiment, each of the tip-end locking teeth 123b has the same size and shape as the locking teeth of the first locking tooth row 113. On the other hand, the base-end locking teeth 123a have a trapezoidal shape with the tip of the sawtooth notched, which is different from the shape of the tip-end locking teeth 123b. That is, the length of the locking surface of the base-side locking tooth 123a (perpendicular to the direction of progression of the overlap) is shorter than the length of the locking surface of the tip-side locking tooth 123b. Furthermore, of the multiple base-side locking teeth 123a, the length of the locking surface of the base-side locking tooth 123a located on the base end side is gradually shorter than the length of the locking surface of the base-side locking tooth 123a located on the tip end side. Here, the length of the locking surface of the locking tooth of the first locking tooth row 113 is defined as d, the length of the locking surface of the tip-side locking tooth 123b is defined as d0, and the lengths of the locking surfaces of the base-side locking teeth 123a are defined as di (i = 1 to 6) in order from the base-end side locking tooth. In this embodiment, d1 is approximately half of d0. Furthermore, in this embodiment, the length d of the locking surface of the locking tooth of the first locking tooth row 113 is the same as the length d0 of the locking surface of the tip-side locking tooth 123b, but it is preferable that d0 ≧ d.

[0045] The length (vertical height) of the locking surface of each locking tooth of the second locking tooth row 123 indicates the amount of locking with the locking tooth of the first locking tooth row 113 that it engages with, and determines the relative depth of engagement between the locking teeth. In other words, the lengths d0 and di (i = 1 to 6) of the locking surface indicate the relative depth of engagement (amount of engagement) between the tip side locking tooth 123b and the locking tooth of the first locking tooth row 113.

[0046] FIG. 11 shows the engagement state of the locking teeth of the first locking tooth row 113 with both the proximal-side locking tooth 123a and the distal-side locking tooth 123b of the second locking tooth row 123 in a state where the proximal-side locking tooth 123a is locked to the first locking portion and a holding space for small-diameter objects is formed. The small-diameter holding space is defined as a relatively small holding space for holding wiring and piping materials (e.g., wiring and piping material PS described later) having a relatively small diameter, which is formed by locking at least a part of the proximal-side locking tooth 123a of the second locking tooth row 123 to the first locking portion.

[0047] As shown in FIG. 11, the locking surface of the distal-side locking tooth 123b located on the distal side of the second locking tooth row 123 is locked to the entire locking surface of the locking teeth of the first locking tooth row 113. At this time, no gap is formed between the opposing locking teeth. In order to release this locking state, a separation movement of a length d0 (= d) of the locking surface of the distal-side locking tooth 123b is required. On the other hand, the locking surface of the proximal-side locking tooth 123a located on the proximal side of the second locking tooth row 123 is locked to a part of the locking surface of the locking teeth of the first locking tooth row 113. In order to release this locking state, a separation movement of a length di (< d) of the locking surface of the proximal-side locking tooth 123a is required. That is, the engagement depth (in the direction orthogonal to the progress direction of the overlapping) when one locking tooth of the first locking tooth row 113 engages with the proximal-side locking tooth 123a of the second locking tooth row 123 is smaller than the engagement depth when one (the same) locking tooth of the first locking tooth row 113 engages with the distal-side locking tooth 123b of the second locking tooth row 123. Even when the shapes of the locking teeth of the first locking tooth row 113 are different, it is possible to relatively determine the engagement depths of the proximal-side locking tooth 123a and the distal-side locking tooth 123b based on the engagement depth with respect to a specific one of the locking teeth.

[0048] FIG. 12 is a schematic diagram showing the relative movement of the second locking tooth row 123 with respect to the first locking tooth row 113 when the second locking portion is moved relatively outward from the retaining space 101 to release the engaged state shown in FIG. 11 . The second retaining piece 120 is released from the locked state by the second locking portion moving relatively outward from the retaining space 101 with respect to the first locking portion, with the base end side of the second locking portion being the deformation portion. In other words, to release the locked state, the second retaining piece 120 rotates around a deformation starting point 126 located on the base end side of the second locking portion in a direction (radially outward) in which the second locking tooth row 123 moves away from the first locking tooth row 113. In this way, since the second retaining piece 120 rotates around the deformation starting point 126, the amount of movement of the base end portion is smaller than the amount of movement of the tip end portion for a given amount of rotation operation (amount of relative movement of the second locking portion).

[0049] 12, when the second locking portion of the second holding piece 120 moves outward by a predetermined amount of relative movement and the distal locking tooth 123b has completed separation from the first locking tooth row 113, the proximal locking tooth 123a also operates as if it has completed separation from the first locking tooth row 113. Here, when the small diameter holding space is formed, the amount of movement of the second holding piece 120 (second locking portion) outward from the holding space 101 required to release the proximal locking tooth 123a is defined as the first relative movement amount. If the locking surfaces of all the locking teeth in the second locking tooth row 123 are formed with a uniform length d0, the locking operation of the proximal locking tooth cannot be released simply by operating to release the locked state of the distal locking teeth. In other words, the release operation requires not only the amount of (rotational) operation of the tip portion of the second holding piece 120 to separate the tip side locking tooth from one locking tooth, but also an additional amount of (rotational) operation to further deform the tip portion of the second holding piece 120 outward. In contrast, the wiring / piping material holder 100 of this embodiment has an engagement depth of the base side locking tooth 123a that is smaller than the engagement depth of the tip side locking tooth 123b, thereby reducing the amount of operation required to separate the base side locking tooth 123a from the first locking tooth row 113 and bringing the timing (operation time) at which the tip side locking tooth 123b and the base side locking tooth 123a are separated closer together, making it possible to omit the additional operation.

[0050] 13 shows an engagement state between the locking teeth of the first locking tooth row 113 and the tip-side locking teeth 123b of the second locking tooth row 123 in a state where only the tip-side locking teeth 123b are locked in the first locking portion to form a large diameter holding space. The large diameter holding space is defined as a relatively large holding space for holding a relatively large diameter wiring / piping material (for example, wiring / piping material PL described below), which is formed when only some or all of the tip-side locking teeth 123b of the second locking tooth row 123 are locked in the first locking portion.

[0051] 13, the locking surface of the distal locking tooth 123b located on the distal side of the second locking tooth row 123 is locked onto the entire locking surface of the locking teeth of the first locking tooth row 113. To release this locked state, the distal locking tooth 123b must move away from the first locking tooth 113 by the length d0 (= d). On the other hand, the proximal locking tooth 123a located on the proximal side of the second locking tooth row 123 is not locked onto the first locking portion.

[0052] Fig. 14 is a schematic diagram showing the relative movement of second locking tooth row 123 with respect to first locking tooth row 113 when the second locking portion is operated to move relatively outward from holding space 101 to release the engaged state shown in Fig. 13. As shown in Fig. 14, the second locking portion moves outward by a predetermined amount of rotational operation (amount of relative movement of the second locking portion) around deformation starting point 126, thereby releasing the locked state. Here, the amount of operation of second holding piece 120 (second locking portion) outward from holding space 101 required to release the engagement of tip-side locking tooth 123b when the large diameter holding space is formed is defined as the second amount of relative movement.

[0053] In the wiring / piping material holder 100 of this embodiment, when only the distal locking tooth 123b is engaged with the first locking portion to form a large-diameter holding space, the second relative movement of the second locking portion outward from the holding space 101 required to release the distal locking tooth 123b is smaller than the second relative movement of the second locking portion outward from the holding space 101 required to release the distal locking tooth 123b when at least the proximal locking tooth 123a is engaged with the first locking portion to form a small-diameter holding space. In other words, the wiring / piping material holder 100 of this embodiment can minimize the amount of user operation required when holding small-diameter wiring / piping material compared to when holding large-diameter wiring / piping material. As a result, it is possible to minimize degradation in operability and changes in operational feel due to differences in the diameter of the wiring / piping material.

[0054] Next, with reference to Figs. 15 to 18, 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. 15 is a schematic perspective view of the installation structure 10. Fig. 16 is a schematic front view of the installation structure 10. Fig. 17 is an E-E cross-sectional view of the installation structure 10. Fig. 18 is an F-F cross-sectional view of the installation structure 10.

[0055] 15 and 16, 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 surface (installation surface) of the construction material 11. Then, as shown in Fig. 17, the wiring / piping material PS is gripped by the wiring / piping material holder 100, and is arranged so that the arrangement direction is along the vertical direction.

[0056] As shown in Figure 18, in the installation structure 10, the fixing surface 111a 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 111c, thereby fixing the wiring / piping material holder 100 to the construction material 11. At this time, the head of the screw 15 is housed in the recess 111b 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.

[0057] In the installation structure 10, the wiring / piping material PS is held in a closed holding space 101 of the wiring / piping material holder 100. As shown in FIG. 17 , 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 the wiring / piping material PS having the corresponding minimum diameter, all of the locking teeth of the second locking tooth row 123 engage with multiple locking teeth on the base end side 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. In particular, as described in FIG. 11 , both the base end side locking tooth 123a and the tip end side locking tooth 123b of the second locking tooth row 123 engage with the locking teeth of the first locking tooth row 113. 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 PS is maintained in a minimum state.

[0058] 17 and 18, the outer peripheral surface of the wiring / piping material PS is surrounded by the first gripping portion 112 of the first holding piece 110, the second gripping portion 122 of the second holding piece 120, and the abutting portion 142 of the auxiliary piece 140. At this time, the clamped portion 153 of the clamped piece 150 is clamped between the outer peripheral surface of the wiring / piping material PS and the first gripping portion 112, so that the first holding piece 110 and the second holding piece 120 hold the wiring / piping material PS in a pressure-contact state. That is, in the installation structure 10, the wiring / piping material holder 100 stably holds the wiring / piping material PS.

[0059] 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.

[0060] FIG. 19 shows an installation structure 10-2, which is a variation of the installation structure 10 of FIG. 17 , 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, only the locking teeth on the tip side of the second locking tooth row 123 engage with the multiple locking teeth on the tip side 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. 13, only the distal locking tooth 123b of the second locking tooth row 123 engages with the locking tooth of the first locking tooth row 113. 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.

[0061] 19 , the wiring / piping material PL is gripped by the arc-shaped portion of the first gripping portion 112, the arc-shaped portion of the second gripping portion 122, the abutting portion 142 of the auxiliary piece 140, and the inner surface of the clamped portion 153 of the clamped piece 150 each abutting against the outer peripheral surface (outer peripheral surface of the ridge portion) of the wiring / piping material PL. Therefore, the wiring / piping material PL is stably gripped by the wiring / piping material holder 100 so that it does not move freely within the holding space 101. When holding a wiring / piping material PL having a compatible maximum diameter, the holding position of the wiring / 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 / piping material PL or align the wiring / piping material PL.

[0062] 20 shows an installation structure 10-3, which is a modification of the installation structure 10 shown in FIG. 17, in which a medium-diameter wiring / piping material PM is arranged among the corresponding wiring / piping material P. In the installation structure 10-3, the wiring / piping material PM 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 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 particular, a portion of the base-end locking teeth 123a (excluding the base-end locking teeth) of the second locking tooth row 123 and all of the tip-end locking teeth 123b engage with the locking teeth of the first locking tooth row 113.

[0063] That is, as shown in Figures 17, 19 and 20, the wiring and piping material holder 100 of this embodiment is capable of stably holding wiring and piping materials P (PS, PL, PM) of different diameters ranging from the minimum corresponding diameter to the maximum corresponding diameter by appropriately displacing the auxiliary piece 140 and the clamped piece 150 depending on the diameter of the wiring and piping material P to be held.

[0064] Next, with reference to FIGS. 21 and 22, a method for releasing the locked state between the first locking portion and the second locking portion in the wiring / piping material holder 100 that grips the wiring / piping material P will be described.

[0065] As shown in FIG. 21 , a user can use an operating tool T with a thin tip shaft, 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, the operating tool T does not need to be aligned with the pipe axis when performing the release operation. In other words, the wiring / piping material holder 100 of this embodiment has higher operability than conventional release operations in which the operating tool is aligned with the pipe axis (which makes it easy for the handle of the operating tool to interfere with the outer surface of the wiring / piping material). Also, as shown in Figure 21, two separation pieces 121 are provided at the tip of the second holding piece 120, and therefore, with each release operation, one separation piece 121 is displaced, releasing only one of the locked pieces. At this time, the other separation piece remains locked, so the remaining separation pieces 121 must also be released sequentially.

[0066] The release operation will be described in more detail with reference to FIG. 22 . 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. 22( 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. 22( a)). As shown in FIG. 22( b), the tip of the operating tool T is used to lift the release operating portion 128 radially outward from the wiring / piping material P, and the second holding piece 120 is rotated radially outward around the deformation starting point 126, 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 separation piece 121. The operating amount of the operating tool T is as described in FIGS. 12 and 14.

[0067] The following describes the effects of the wiring / piping material holder 100 according to one embodiment of the present invention.

[0068] According to the wiring / piping material holder 100 of one embodiment of the present invention, the depth of engagement (in a direction perpendicular to the direction of progression of the overlap) when one locking tooth of the first locking tooth row 113 engages with the base-end locking tooth 123a of the second locking tooth row 123 is smaller than the depth of engagement when one (the same) locking tooth of the first locking tooth row 113 engages with the tip-end locking tooth 123b of the second locking tooth row 123. This effectively reduces the amount of operation required to move the base-end locking tooth 123a away from the one locking tooth when operating to relatively move the second locking part outward from the holding space 101, and can bring the timing (point of operation) at which the tip-end locking tooth 123b and the base-end locking tooth 123a are released closer together. That is, in the release operation, in addition to the amount of manipulation of the tip portion of the second holding piece 120 that separates the tip side locking tooth 123b from one locking tooth, it is possible to effectively reduce or eliminate the additional amount of manipulation that further deforms the tip portion of the second holding piece 120 outward. Therefore, the wiring / piping material holder 100 of this embodiment makes the release operation easier.

[0069] The wiring and piping material support of the present invention can be described as having the following configuration according to the above embodiment. (composition) A wiring and piping material holder for holding wiring and piping materials, a first holding piece extending from a base end to a tip end; a second holding piece connected to the first holding piece, extending from the base end to the tip end and cooperating with the first holding piece to surround the wiring / piping material and hold it along the installation direction; A tip portion of the first holding piece and a tip portion of the second holding piece overlap to form an annular holding space surrounding the wiring / piping material, and the second holding piece overlaps with the first holding piece from outside the holding space, a first locking portion and a second locking portion are provided on an outer surface of the first holding piece and an inner surface of the second holding piece, respectively, and the first holding piece and the second holding piece are locked to each other so as to maintain the overlapping of the first holding piece and the second holding piece; the first locking portion and the second locking portion are configured to allow relative movement in a forward direction that increases the amount of overlap between the first holding piece and the second holding piece, and to restrict relative movement in a backward direction that decreases the amount of overlap, and to release the locked state by the second locking portion moving relatively to the outside of the holding space with respect to the first locking portion, with a base end side of the second holding piece closer to the second locking portion as a deformation site (deformation starting point), the first locking portion comprises a first locking tooth row consisting of a plurality of locking teeth formed in the direction of progression of the polymerization, and the second locking portion comprises a second locking tooth row consisting of a plurality of locking teeth formed in the direction of progression of the polymerization, and as the amount of polymerization increases, the locking teeth that engage with each other are switched, The second locking tooth row is composed of one or more base-end locking teeth located on the base-end side of the second holding piece and one or more tip-end locking teeth located on the tip-end side of the second holding piece, and the engagement depth when one locking tooth of the first locking tooth row engages with the base-end locking tooth is smaller than the engagement depth when one locking tooth of the first locking tooth row engages with the tip-end locking tooth, and A wiring / piping material holder characterized in that, when only the tip-side locking tooth is engaged with the first locking portion to form a large diameter retaining space, the amount of relative movement (operation amount) of the second locking portion toward the outside of the retaining space required to release the tip-side locking tooth is smaller than the amount of relative movement of the second locking portion toward the outside of the retaining space when at least the base-side locking tooth is engaged with the first locking portion to form a small diameter retaining space.

[0070] 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.

[0071] (1) The wiring and piping material holder of the present invention is not limited to the configuration of the above-described embodiment. FIGS. 23 to 26 show a wiring and piping material support 200 according to a second embodiment of the present invention. The wiring and piping material support 200 differs from the above-described embodiment in the configuration of the first locking portion (first locking tooth row 213) and the second locking portion (second locking tooth row 223). In particular, as shown in FIGS. 23 and 24 , the first locking tooth row 213 is formed only over a shorter range on a portion of the tip side of the first side portion 211 a of the base portion 211 of the first holding piece 210. Because the first locking tooth row 213 does not extend toward the base end, as shown in FIG. 25 , when the second holding piece 220 is tightened to form a small-diameter holding space, a portion of the tip-side locking teeth 223 b of the second locking tooth row 223 is not locked by the first locking tooth row 213. 24, the second locking tooth row 223 is composed of one base-end locking tooth 223a on the base-end side and the remaining multiple tip-end locking teeth 223b. The locking surface of the base-end locking tooth 223a is smaller than the locking surface of the tip-end locking tooth 223b. In other words, the engagement depth when one locking tooth of the first locking tooth row 213 engages with the base-end locking tooth 223a is smaller than the engagement depth when one locking tooth of the first locking tooth row 213 engages with the tip-end locking tooth 223b. 26, when a disengagement operation is performed in a case where a small diameter holding space is formed, the second locking portion of the second holding piece 220 moves outward by a predetermined amount of relative movement, and when the tip-side locking tooth 223b has completed separation from the first locking tooth row 213, the base-side locking tooth 223a also operates as if it has similarly completed separation from the first locking tooth row 213, as in the first embodiment. That is, the wiring / piping material support 200 of the second embodiment has an engagement depth of the base-side locking tooth 223a that is smaller than the engagement depth of the tip-side locking tooth 223b, thereby reducing the amount of operation required to separate the base-side locking tooth 223a from the first locking tooth row 213, and by bringing the timing (time of operation) at which the tip-side locking tooth 223b and the base-side locking tooth 223a are separated closer, it is possible to omit an additional operation.

[0072] (2) 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 holding piece is provided with a fixing portion (fixing surface and insertion portion) and the second holding piece is provided with a release operation portion, but the present invention is not limited to this. In other words, the second holding piece may be a holding piece that includes a release operation portion and also has a fixing portion like the first holding piece of the above embodiment.

[0073] (3) 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, two separate pieces are formed at the tip portion of the second holding piece, but the present invention is not limited to this. In other words, the tip portion of the second holding piece does not have to be separate, and in this case, the lock can be released with a single operation.

[0074] (4) 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 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.

[0075] (5) The wiring / piping material holder of the present invention is not limited to the configuration of the above embodiment. For example, at least one of the auxiliary piece, the clamped piece, the connecting mechanism, and the blocking wall portion may be omitted from the wiring / piping material holder of the above embodiment.

[0076] (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, a locking tooth row with a large number of locking teeth is formed on the side of the first holding piece that is fixed to the structure, and a locking tooth row with a small number of locking teeth is formed on the side of the second holding piece. However, the relationship between the first locking tooth row and the second locking tooth row may be reversed, such that a locking tooth row with a large number of locking teeth is formed on the inner surface of the second holding piece, and a locking tooth row with a small number of locking teeth is formed on the outer surface of the first holding piece. Furthermore, the number of locking teeth in the first locking tooth row and the number of locking teeth in the second locking tooth row may be increased or decreased as desired within the technical scope of the present invention. Furthermore, the number of base-side locking teeth and the number of tip-side locking teeth in the second locking tooth row may also be increased or decreased as desired within the technical scope of the present invention.

[0077] (7) 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 multiple locking teeth of the first locking tooth row are formed with the same shape, but they may be formed with different shapes as long as they can lock the locking teeth of the second locking tooth row. Furthermore, in the above embodiment, the base-end locking teeth of the second locking tooth row are trapezoidal with the apex of the sawtooth cut out, but they may have any other shape as long as the engagement depth is relatively small compared to the tip-end locking teeth. For example, the base-end locking teeth may have a triangular shape that is simply shortened in the height direction to shorten the sawtooth (locking surface).

[0078] 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.
