Description

Technical Field

[0001] The present invention relates to a wiring and pipe material fixture for holding wiring and pipe materials, and a laying device disposed on a structure.

Background Art

[0002] Conventionally, various wiring and pipe material fixtures have been used for the purpose of being fixed to structures such as building construction surfaces and operation materials, and supporting and laying wiring and pipe materials with respect to the structures.

[0003] For example, Patent Document 1 discloses a wiring and pipe material fixture for holding wiring and pipe materials having different outer diameters and fixing them to structures such as wall surfaces and ceiling backs. Hereinafter, in this paragraph, the reference numerals of Patent Document 1 are shown in parentheses. The wiring and pipe material fixture (1) includes a belt body (2) and a pair of overlapping portions (3) including one overlapping portion (3a) and the other overlapping portion (3b) facing each other with an opening (C) interposed therebetween at both ends thereof. The belt body (2) is pre-bent into a shape that occupies a part of a circle having a substantially inner diameter (d). The overlapping portion (3) has a function as a fixing seat that reduces the inner diameter (d) of the belt body (2) by relatively moving the overlapping surface (3c) of one overlapping portion (3a) relative to the overlapping surface (3d) of the other overlapping portion (3b) while locking the overlapping surface (3c) of one overlapping portion (3a) to the overlapping surface (3d) of the other overlapping portion (3b), and after the diameter reduction, the two overlapping portions are fixed by a fixing tool in a state where they are overlapped with each other. A locking portion (3g) and a long hole (3e) are formed in one overlapping portion (3a), and a serrated locked portion (3f) and a long hole (3e) extending in the substantially central portion in the left-right direction of the other overlapping portion (3b) are formed. In order to hold a wiring and pipe material (P) having a smaller diameter than the inner diameter (d), while pressing the locking portion (3g) of one overlapping portion (3a) against the locked portion (3f) of the other overlapping portion (3b), the locking portion (3g) is pushed into the belt body (2) side to reduce the inner diameter (d) to the inner diameter (D2). Thereafter, in order to tighten the screw (4), the screw (4) is tightened until the overlapping surfaces (3c) and (3d) of the two overlapping portions (3a, 3b) are in close contact with each other. By this operation, most of the outer peripheral surface of the pipe (P) is in close contact with the belt body (2), and the pipe (P) is firmly fixed to the fixing target surface (B).

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the wiring and pipe material fixture of Patent Document 1, the inner diameter of the original-shaped band corresponds to the diameter of the wiring and pipe material with the maximum corresponding diameter. To hold a wiring and pipe material with a smaller diameter, one overlapping portion is relatively moved to the proximal end side (band side) with respect to the other overlapping portion from the original shape, and the locking portion and the locked portion are locked to reduce the band to a predetermined inner diameter. At that time, the portion of the band continuously provided on one overlapping portion is preferentially deformed so as to bend inward, while the portion on the opposite side of the overlapping portion is difficult to deform from the original arc shape. Therefore, when the diameter of the wiring and pipe material is significantly smaller than the inner diameter of the original shape of the band, the band cannot follow the outer peripheral shape of the wiring and pipe material and deform, and the inner peripheral shape of the band and the outer peripheral shape of the wiring and pipe material are greatly different. As a result, the wiring and pipe material cannot be firmly sandwiched between the opposing inner surfaces of the band, and the problem was that stable holding could not be achieved.

[0006] The present invention has been made to solve the above problems, and an object thereof is to provide a wiring and pipe material fixture capable of more stably holding and fixing a wiring and pipe material with a smaller diameter among at least two types of wiring and pipe materials, and a laying device.

Means for Solving the Problems

An openable and closable opening portion is formed between one end and the other end of the holding portion for introducing the wiring / wiring pipe material into the inner space of the holding portion. A first extending portion is formed at one end of the holding portion and extends in a direction away from the holding portion. A locking portion is formed on the first extending portion and extends from the proximal end side to the distal end side in the extending direction of the first extending portion. A second extending portion is formed at the other end of the holding portion and extends so as to be capable of overlapping with the first extending portion. A locked portion is formed on the second extending portion and is locked to the locking portion at positions with different extending directions so as to maintain the overlapping position of the first extending portion and the second extending portion. It includes a fixing portion for fixing the first extending portion and the second extending portion to the structure in a state where they overlap each other. The inner peripheral surface of the holding portion forms a substantially elliptical shape having a major axis and a minor axis in its original shape, and one end portion of the major axis is closer to the opening portion than both end portions of the minor axis. When the locked portion is relatively moved and locked to one side in the extending direction of the locking portion, the inner peripheral surface of the holding portion is deformed into a substantially elliptical shape having a minor axis smaller than the original shape.

[0010] One embodiment of the present invention The laying device is The above embodiment a wiring and pipe material fixture of a first wiring and pipe material having a first outer diameter larger than the distance between the inner surfaces of the holding portion facing each other in the minor axis direction in the original shape of the holding portion, and a second wiring and pipe material having a second outer diameter smaller than the facing distance between the inner surfaces of the holding portion facing each other in the minor axis direction in the original shape of the holding portion, and a wiring and pipe material group including the same, The wiring and pipe material fixture is characterized in that both the first wiring and pipe material and the second wiring and pipe material selected from the wiring and pipe material group can be fixed to a structure while being held by the holding portion.

[0011] A further embodiment of the present invention The laying device is a wiring and pipe material group composed of at least two types of wiring and pipe materials having different outer diameters, corresponding to any wiring and pipe material selected from the wiring and pipe material group, and configured to hold the selected wiring and pipe material along the laying direction and fix it to the installation surface of the structure Of the above embodiment a laying device including a wiring and pipe material fixture, The wiring and pipe material group includes a first wiring and pipe material having a first outer diameter larger than the distance between the inner surfaces of the holding portion facing each other in the minor axis direction in the original shape of the holding portion, and a second wiring and pipe material having a second outer diameter smaller than the distance between the inner surfaces of the holding portion facing each other in the minor axis direction in the original shape of the holding portion, When holding the first wiring and pipe material, the holding portion is deformed so as to follow the outer periphery of the first wiring and pipe material, and the locked portion is locked to the locking portion at a first relative position displaced from the original shape toward the tip side. When holding the second wiring and piping material, the long axis of the holding portion is deformed so as to narrow the facing distance between the inner surfaces of the holding portion in the short axis direction while tilting in the direction along the installation surface, and the locked portion is locked to the locking portion at a second relative position shifted from the original shape to the proximal end side.

[0012] One embodiment of the present invention The laying device is a wiring and piping material group composed of at least two types of wiring and piping materials, including a first wiring and piping material having a first outer diameter and a second wiring and piping material having a second outer diameter smaller than the first outer diameter, a wiring and piping material fixing tool that corresponds to both the first wiring and piping material and the second wiring and piping material selected from the wiring and piping material group, and is configured to hold the selected wiring and piping material along the laying direction and fix it to a structure. The laying device includes the wiring and piping material fixing tool a holding portion that extends in a strip shape from one end to the other end and can hold the wiring and piping material by surrounding the outer circumference of the wiring and piping material by elastic deformation, an openable and closable opening portion formed between one end and the other end of the holding portion for introducing the wiring and piping material into the inner space of the holding portion, a first extending portion formed at one end of the holding portion and extending in a direction away from the holding portion, a locking portion formed on the first extending portion and extending from the proximal end side to the distal end side in the extending direction of the first extending portion, a second extending portion formed at the other end of the holding portion and extending so as to be superposable with the first extending portion, a locked portion formed on the second extending portion and locked to the locking portion at positions with different extending directions so as to maintain the superposed position of the first extending portion and the second extending portion, and a fixing portion for fixing the first extending portion and the second extending portion to the structure in a superposed state with each other. The inner peripheral surface of the holding portion has a length that allows the first extension portion and the second extension portion to overlap each other and be fixed to the structure by the fixing portion while surrounding the outer periphery of the first wiring and pipe material. When holding the second wiring and pipe material, a pressure contact portion that presses against the second wiring and pipe material so as to be sandwiched between surfaces facing in the first axial direction and a surplus length portion that forms a gap between at least a surface facing in a second axial direction orthogonal to the first axial direction and the outer peripheral surface of the second wiring and pipe material are formed on the inner peripheral surface of the holding portion.

Advantages of the Invention

[0013] One embodiment of the present invention (paragraph 0007) According to the wiring and pipe material fixture, the inner peripheral surface of the holding portion forms a substantially elliptical shape having a major axis and a minor axis in its original shape, and one end of the major axis is located closer to the open portion than both ends of the minor axis. The wiring and pipe material fixture can arrange the wiring and pipe material in the inner space of the substantially elliptical shape of the holding portion in its original shape and sandwich the wiring and pipe material between the inner surfaces facing each other in the minor axis direction. In particular, when the locked portion moves relative to and is locked to one side (the base end side or the tip end side) in the extending direction of the locking portion, the holding portion deforms to form a substantially elliptical shape having a minor axis smaller than its original shape. Thereby, when holding a wiring and pipe material with a smaller diameter, the holding portion can firmly sandwich the outer peripheral surface of the wiring and pipe material between the inner surfaces facing each other in the minor axis direction within the inner space having a smaller substantially elliptical shape. Therefore, the wiring and pipe material fixture of the present invention can more stably hold and fix the wiring and pipe material with a smaller diameter among at least two types of wiring and pipe materials. 。

[0014] According to the wiring and pipe fixture of a further embodiment of the present invention (paragraph 0008), the aboveIn addition to the effects of the invention, in the original shape of the holding portion, the major axis is inclined at a predetermined angle with respect to the fixed surface. Then, in order to hold the wiring and pipe materials with a small diameter, when the second extended portion (locked portion) is moved to the proximal end side in the extending direction of the first extended portion (locking portion), a force is applied in the direction in which the other end of the major axis falls, and the holding portion is deformed, so that the angle of the major axis with respect to the fixed surface becomes smaller (that is, the major axis tilts in the direction parallel to the floor). As a result, when the wiring and pipe material fixture is fixed to the structure via the fixing portion, the outer surface of the holding portion is supported from below by the structure, and it is possible to fix the wiring and pipe materials more firmly to the structure.

[0015] According to the wiring and pipe fixture of a further embodiment of the present invention (paragraph 0009), the above According to the laying device, in addition to the effects of the invention, the locking teeth are displaced in the extending direction between the first row of locking tooth rows and the second row of locking tooth rows adjacent to each other in the arrangement direction orthogonal to the extending direction, so that the locking teeth adjacent to each other in the arrangement direction come into contact with each other, and the displacement of the first extended portion and the second extended portion in the arrangement direction in the overlapped state is restricted. Therefore, it is possible to more stably maintain the overlap of the first extended portion and the second extended portion.

[0016] One embodiment of the present invention (paragraph 0010) According to the laying device of The above it is possible to exhibit the effects of the invention as a laying device. Therefore, the laying device of the present invention can also stably fix the second wiring and pipe materials with a smaller diameter to the structure in the same manner as the first wiring and pipe materials.

[0017] A further embodiment of the present invention (paragraph 0011) According to the laying device of The aboveThe effects of the invention can be exerted as a laying device. Further, when holding the first wiring and pipe material, the holding portion is deformed so as to follow the outer periphery of the first wiring and pipe material, and the locked portion is locked to the locking portion at a first relative position shifted from the original shape toward the tip side. Thereby, the laying device can stably fix the first wiring and pipe material having a larger diameter than the diameter of the wiring and pipe material that can be held in the original shape (corresponding to the minor axis of the original shape) to the structure. Also, when holding the second wiring and pipe material, the major axis of the holding portion is tilted in the direction along the installation surface while deforming so as to narrow the facing distance between the inner surfaces of the holding portions facing each other in the minor axis direction, and the locked portion is locked to the locking portion at a second relative position shifted from the original shape toward the base end side. Thereby, the laying device can stably fix the second wiring and pipe material having a smaller diameter than the diameter of the wiring and pipe material that can be held in the original shape (corresponding to the minor axis of the original shape) to the structure. Therefore, the laying device of the present invention can stably fix the second wiring and pipe material having a smaller diameter to the structure, similar to the first wiring and pipe material.

[0018] One embodiment of the present invention (paragraph 0012) According to the laying device, the holding portion can be fixed to the structure by the fixing portion with the first extending portion and the second extending portion being superposed on each other while surrounding the outer periphery of the first wiring and pipe material. Thereby, the laying device can stably fix the first wiring and pipe material having a larger diameter to the structure. On the other hand, when holding the second wiring and pipe material having a smaller diameter, a pressure contact portion that presses against the second wiring and pipe material so as to sandwich it between surfaces facing in the first axial direction is formed on the inner peripheral surface of the holding portion, and a surplus length portion that forms a gap (does not contact the outer peripheral surface of the wiring and pipe material) is formed between the surface facing at least in the second axial direction orthogonal to the first axial direction and the outer peripheral surface of the second wiring and pipe material. That is, when holding the second wiring and pipe material having a smaller diameter, the holding portion is deformed so as to form a surplus length portion in the second axial direction within the inner space, thereby effectively narrowing the interval between the pressure contact portions facing in the first axial direction and firmly sandwiching the outer peripheral surface of the second wiring and pipe material with the inner peripheral surface of the holding portion. Therefore, the laying device of the present invention can stably fix the second wiring and pipe material having a smaller diameter to the structure, similar to the first wiring and pipe material.

Modes for Carrying Out the Invention

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

[0021] The wiring and pipe material fixture 100 of an embodiment of the present invention is fixed to an installation surface of a structure such as a floor or a ceiling, and is used for the purpose of arranging the wiring and pipe material 11 with respect to the structure. Further, the arranging device 10 is a device including a wiring and pipe material group composed of at least two types of wiring and pipe materials 11 having different outer diameters and the wiring and pipe material fixture 100 in order to arrange the wiring and pipe material 11 having a predetermined outer diameter selected from the wiring and pipe material group with respect to the installation surface of the structure. The wiring and pipe material group includes two or more types of wiring and pipe materials 11 having different outer diameters in the range from the corresponding minimum diameter to the corresponding maximum diameter. Note that in the present embodiment, the installation surface of the structure to which the wiring and pipe material fixture 100 is fixed is the floor surface, and the wiring and pipe material 11 is exemplified as a corrugated flexible pipe having a circular cross-sectional shape. Further, the wiring and pipe material 11 is formed such that the peak portions (large diameter portions) and the valley portions (small diameter portions) are alternately continuous in the longitudinal direction. However, it goes without saying that the present embodiment is merely an example of the present invention, and does not limit the use and configuration thereof as long as it does not deviate from the technical scope of the present invention. Hereinafter, the configuration of the wiring and pipe material fixture 100 of the present invention will be described.

[0022] Figs. 1(a) and (b) are perspective views of the wiring and pipe material fixture 100 of an embodiment of the present invention. Fig. 2 is a front view of the wiring and pipe material fixture 100. Figs. 3(a) to (d) are a plan view, a left side view, a right side view and a bottom view of the wiring and pipe material fixture 100. Figs. 4 and 5 are cross-sectional views at respective portions of the wiring and pipe material fixture 100.

[0023] The wiring and pipe fixture 100 of this embodiment is configured to arrange the wiring and pipe material 11 along a predetermined arrangement direction along the installation surface of the structure by being fixed to the structure while holding or gripping the wiring and pipe material 11 in the inner space 103 of the strip-shaped holding portion 101.

[0024] As shown in FIGS. 1 to 3, the wiring and pipe fixture 100 includes a holding portion 101 extending in a strip shape from one end to the other end, an openable and closable opening portion 104 formed between one end and the other end of the holding portion 101 for introducing the wiring and pipe material 11 into the inner space 103 of the holding portion 101, a first extending portion 111 formed at one end of the holding portion 101 and extending in a direction away from the holding portion 101, a locking tooth row 115 formed on the first extending portion 111 and serving as a locked portion for locking a locking portion, a second extending portion 116 formed at the other end of the holding portion 101 and extending in a manner that can be superposed opposite to the first extending portion 111, a hanging claw 118 formed on the second extending portion 116 and serving as a locked portion to be locked by the locking portion, and fixing portions (first fixing hole 113, second fixing hole 117) for fixing the first extending portion 111 and the second extending portion 116 to the structure in a superposed state with each other. And the wiring and pipe fixture 100 is configured to correspond to any wiring and pipe material 11 selected from the corresponding wiring and pipe material group, hold the selected wiring and pipe material 11 along the arrangement direction, and fix it to the installation surface of the structure.

[0025] In this embodiment, the wiring and pipe fixture 100 is integrally formed of synthetic resin. In the strip-shaped holding portion 101, while having flexibility and elasticity, the first extending portion 111 and the second extending portion 116 fixed to the structure are relatively rigid.

[0026] In addition, the wiring and pipe fixture 100 is configured to be able to hold two or more types of wiring and pipe materials 11 having different outer diameters from the corresponding minimum diameter to the corresponding maximum diameter by the holding portion 101. Here, among the corresponding wiring and pipe materials 11, the wiring and pipe material having a reference diameter (or intermediate diameter) corresponding to the original shape of the holding portion 101 (the distance between the inner surfaces in the minor axis direction of the inner peripheral surface of the holding portion 101) is represented by 11A, the wiring and pipe material having the corresponding maximum diameter is represented by 11B, and the wiring and pipe material having the corresponding minimum diameter is represented by 11C. Further, the corresponding maximum diameter of the wiring and pipe material 11 is determined by the diameter of the maximum long body that can be fixed to the structure by overlapping the first extended portion 111 and the second extended portion 116 in a state where its outer peripheral surface is surrounded by the (closed) holding portion 101. On the other hand, the corresponding minimum diameter of the wiring and pipe material is determined by the diameter of the minimum long body that can be fixed to the structure by overlapping the first extended portion 111 and the second extended portion 116 in a state where the wiring and pipe material 11 is held without moving into the inner space 103. Further, the outer diameter of the wiring and pipe material 11 referred to here is the outer diameter of the peak portion in the case of a corrugated flexible pipe. Hereinafter, each component of the wiring and pipe fixture 100 of the present embodiment will be described in more detail.

[0027] The holding part 101 is composed of a strip-shaped body extending in a band shape from one end on the installation surface side to the other end on the opposite side. As shown in FIG. 5, the holding part 101 is a thinner region compared to the first extending part 111 and the second extending part 116, and is elastically deformable over the entire circumferential direction. The holding part 101 has an inner circumferential surface and an outer circumferential surface, and by surrounding the outer circumference of the wiring and pipe material 11 with its inner circumferential surface, the wiring and pipe material 11 can be held inside the inner space 103. That is, the inner circumferential surface of the holding part 101 has a length that can fix the first extending part 111 and the second extending part 116 to each other and to the structure by the fixing parts (the first fixing hole 113 and the second fixing hole 117) in a state of surrounding the outer circumference of the wiring and pipe material 11B with the corresponding maximum diameter. Further, a plurality of protrusions 102 are provided protruding along the circumferential direction on the inner circumferential surface of the holding part 101. The plurality of protrusions 102 function to enter the groove part of the wiring and pipe material 11 and prevent the wiring and pipe material 11 from shifting in the laying direction. And one end and the other end of the holding part 101 are close to each other, and an openable and closable opening part 104 is formed therebetween. The opening part 104 can be freely opened and closed according to the bending deformation of the holding part 101.

[0028] In addition, in its original shape, the holding part 101 is curved so as to draw a substantially elliptical curve from one end to the other end. Here, the original shape means the natural state in which the holding part 101 is not elastically deformed. And, the inner peripheral surface of the holding part 101 forms a substantially elliptical shape having a major axis L and a minor axis S in the original shape. The "substantially" elliptical shape defined by the inner peripheral surface of this holding part 101 includes a shape that can be approximated by an elliptical curve. That is, as long as the holding part 101 has a shape that can be approximated by an elliptical curve, it may have a radially inward and outward protruding portion or the like in a part thereof. The major axis L and the minor axis S are orthogonal at the center point of the inner space 103 (elliptical curve) and are defined based on the approximated elliptical curve. Also, one end portion of the major axis L is positioned closer to the opening portion 104 than both end portions of the minor axis S. In particular, one end portion of the major axis L is disposed at the same position as or in the vicinity of the opening portion 104. And, the major axis L is inclined so as to be spaced apart in the vertical direction from the fixing surface 112 (or installation surface) of the first extending portion 111 from one end portion toward the other end portion. That is, the major axis L and the fixing surface 112 (or installation surface) are inclined at a predetermined inclination angle. Also, the length of the minor axis S of the original shape of the holding part 101 corresponds to the facing distance between the opposing inner surfaces of the holding part 101, and the wiring / wiring pipe material 11 having a predetermined diameter is sandwiched by the opposing inner peripheral surfaces.

[0029] The holding part 101 presses the wiring / wiring pipe material 11 having a diameter smaller than the distance between the inner surfaces of the holding part 101 facing each other in the minor axis direction from the facing direction in the original shape (natural state). And, it is possible to hold the wiring / wiring pipe material 11 in a state where a gap is formed between the held wiring / wiring pipe material 11 and the inner surface of the holding part 101 in the major axis direction. In particular, the ellipticity (minor axis S / major axis L) of the elliptical shape of the holding part 101 in the original shape is preferably determined within the range of about 0.5 to 0.9 in order to hold the circular wiring / wiring pipe material 11 having different outer diameters. Also, the inclination angle is preferably determined within the range of about 30 to 80 degrees.

[0030] The first extended portion 111 is formed at one end of the holding portion 101 and extends in a flat plate shape in a direction away from the holding portion 101. The first extended portion 111 extends longitudinally along the extending direction from the base end connected to one end of the holding portion 101 to the tip end. The first extended portion 111 has a fixing surface 112 fixed to the installation surface of the structure Object on the bottom surface side, and on the opposite side thereof, it has a superposed surface that superposes with the second extended portion 116. Further, a first fixing hole 113 extending in the extending direction is formed at the center in the width direction of the first extended portion 111. That is, the first fixing hole 113 is an elongated hole for a screw 15 having a predetermined length in the extending direction.

[0031] The second extended portion 116 is formed at the other end of the holding portion 101 and extends in a flat plate shape in a direction away from the holding portion 101 so as to be superposable with the first extended portion 111. The second extended portion 116 extends along the extending direction from the base end connected to the other end of the holding portion 101 to the tip end. The second extended portion 116 has a superposed surface on the surface facing the lower side (the first extended portion 111 side). Further, in its original shape, the second extended portion 116 is spaced apart from the first extended portion 111 and extends in parallel. That is, the first extended portion 111 and the second extended portion 116 face each other substantially in parallel via the superposed surface. Note that the length of the second extended portion 116 in the extending direction is shorter than that of the first extended portion 111. And a second fixing hole 117 for the screw 15 is formed at approximately the center of the second extended portion 116. The first fixing hole 113 and the second fixing hole 117 are configured such that even if the relative positions in the extending direction of the first extended portion 111 and the second extended portion 116 are displaced from the base end side to the tip end side, they communicate with each other and the screw 15 can be driven in. Further, on the upper surface of the second extended portion 116, a reference line for aligning a nail gun (a nailing machine) is formed around the second fixing hole 117.

[0032] Further, over most of the extending direction of the overlapping surface of the first extended portion 111, a locking tooth row 115 as a locking portion is formed. The locking tooth row 115 is composed of a plurality of locking teeth formed continuously in the extending direction. Each locking tooth constituting the locking tooth row 115 has an inclined surface on the tip side and a locking surface standing substantially perpendicular to the overlapping surface on the opposite side, forming a sawtooth shape. On the other hand, near the tip of the second extended portion 116, a hanging claw 118 protruding from the overlapping surface thereof toward the first extended portion 111 is formed. The hanging claw 118 has an inclined surface on the base end side and a locking surface standing substantially perpendicular to the overlapping surface on the tip side, forming a claw shape or a sawtooth shape. The hanging claw 118 is configured to be locked to any one of the locking teeth of the locking tooth row 115 when the overlapping surfaces of the first extended portion 111 and the second extended portion 116 come into contact with each other. Further, the hanging claw 118 faces the locking tooth row 115 at the initial position in the extending direction in its original shape. And the locking tooth row 115 allows relative movement only in one direction toward the base end side with respect to the sawtooth-shaped locking teeth of the hanging claw 118 and acts to lock to the tip side. That is, the locking tooth row 115 and the hanging claw 118 are configured to engage with each other at a plurality of different positions in the extending direction so as to maintain the overlapping position of the first extended portion 111 and the second extended portion 116. And due to the engagement relationship between the locking tooth row 115 and the hanging claw 118, the second extended portion 116 is restricted from relatively sliding to the tip side of the first extended portion 111 and expanding the inner space 103.

[0033] Also, in the present embodiment, as shown in FIG. 4(a), two rows of locking tooth rows 115A and 115B are aligned in the extending direction and provided adjacent to each other in the width direction (the arrangement direction orthogonal to the extending direction) of the first extending portion 111. The first row of locking tooth row 115A and the second row of locking tooth row 115B have locking teeth arranged side by side in the extending direction at the same pitch. On the other hand, the first row of locking tooth row 115A and the second row of locking tooth row 115B are displaced from each other in the extending direction by a distance approximately half the length of the locking teeth in the extending direction. That is, the locking teeth are arranged in a staggered manner between the adjacent locking tooth rows 115A and 115B. Similarly, as shown in FIG. 4(b), the engaging claw 118 is composed of a first claw piece 118A and a second claw piece 118B. The first claw piece 118A and the second claw piece 118B are displaced from each other in the extending direction so as to correspond to the first row of locking tooth row 115A and the second row of locking tooth row 115B, respectively. And in a state where the claw pieces 118A and 118B are engaged with the locking tooth rows 115A and 115B, respectively, the claw piece 118A (or 118B) abuts against the locking tooth row 115B (or 115A) from the width direction. Thereby, the displacement of the first extending portion 111 and the second extending portion 116 in the width direction is restricted. In the present embodiment, all of the plurality of locking teeth are displaced in the extending direction, but the present invention is not limited to this, and a part of the plurality of locking teeth may be displaced in the extending direction. Alternatively, locking teeth may be arranged side by side at different pitches in the extending direction between the first row of locking tooth row and the second row of locking tooth row adjacent to each other in the arrangement direction orthogonal to the extending direction.

[0034] In the wiring and pipe material fixture 100 of the present embodiment, when the hanging claw 118 moves from the initial position of the original shape to the tip side (the other side in the extending direction) of the locking tooth row 115 and is locked, the inner space 103 of the holding portion 101 deforms so as to expand. In particular, when holding the first wiring and pipe material 11 having an outer diameter larger than the distance between the inner surfaces of the holding portion 101 facing each other in the minor axis direction in the original shape of the holding portion 101, the holding portion 101 deforms along the outer periphery of the first wiring and pipe material 11, and the hanging claw 118 is locked to the locking tooth row 115 at the first relative position shifted from the initial position of the original shape to the tip side. On the other hand, when the hanging claw 118 moves from the initial position of the original shape to the base end side (one side in the extending direction) of the locking tooth row 115 and is locked, the inner peripheral surface of the holding portion 101 deforms into a substantially elliptical shape having a minor axis smaller than the minor axis S of the original shape. In particular, when holding the second wiring and pipe material 11 having an outer diameter smaller than the distance between the inner surfaces of the holding portion 101 facing each other in the minor axis direction in the original shape of the holding portion 101, the holding portion 101 deforms while tilting its major axis L in the direction along the installation surface and narrowing the facing distance between the inner surfaces of the holding portion 101 in the minor axis S direction, and the hanging claw 118 is locked to the locking tooth row 115 at the second relative position shifted from the initial position of the original shape to the base end side.

[0035] Regarding the above aspect of the wiring and pipe material fixture 100 of the present embodiment, it will be described more specifically by exemplifying installation structures in which wiring and pipe materials 11 having different outer diameters (the wiring and pipe material 11A with the reference diameter, the wiring and pipe material 11B with the corresponding maximum diameter, and the wiring and pipe material 11C with the corresponding minimum diameter) are arranged.

[0036] FIG. 6 is a schematic perspective view of an installation structure in which a wiring and pipe material 11 is installed on an installation surface of a structure by the wiring and pipe material fixture 100 and the installation device 10 of the present embodiment. In the present embodiment, the installation surface of the structure is a floor surface. As shown in FIG. 6, the wiring and pipe material fixture 100 holds the wiring and pipe material 11 along the installation direction. The wiring and pipe material 11 penetrates the closed annular inner space 103 of the holding portion 101 in the installation direction. Then, the first extension portion 111 and the second extension portion 116 of the wiring and pipe material fixture 100 overlap and are fixed to the installation surface with screws 15, thereby constructing an installation structure in which the wiring and pipe material 11 is installed along the installation surface. Although not shown, in the installation structure, at a plurality of locations in the installation direction of the wiring and pipe material 11, a plurality of wiring and pipe material fixtures 100 hold and fix the wiring and pipe material 11 to the installation surface.

[0037] FIG. 7 is a schematic cross-sectional view of a first installation structure in which a wiring and pipe material 11A having a reference diameter selected from a corresponding wiring and pipe material group is installed on an installation surface by a wiring and pipe material fixture 100. Here, the outer diameter of the wiring and pipe material 11A corresponds to the distance between the inner surfaces of the holding portion 101 facing the short axis direction in the original shape of the holding portion 101. As shown in FIG. 7, with the inner peripheral surface of the holding portion 101 surrounding the outer periphery of the wiring and pipe material 11A, the first extension portion 111 and the second extension portion 116 are overlapped with each other and fixed to the structure with screws 15 through the first fixing hole 113 and the second fixing hole 117. At this time, the hanging claw 118 is engaged with the locking tooth row 115 at the initial position in the extension direction in the original shape.

[0038] In addition, the substantially elliptical shape of the inner peripheral surface of the holding portion 101 is maintained substantially in its original shape (or a substantially elliptical shape reduced by the amount of deformation that closes the opening portion 104). The center of the wiring and pipe material 11A is located at the intersection of the major axis L and the minor axis S, and the inner surfaces of the inner peripheral surface of the holding portion 101 that face each other in the minor axis direction are in pressure contact with the outer peripheral surface of the wiring and pipe material 11A. Here, on the inner peripheral surface of the holding portion 101, there are formed a pressure contact portion 105 that is in pressure contact with the wiring and pipe material 11A so as to sandwich it between the surfaces facing each other in the minor axis direction, and a surplus length portion 106 that forms a gap between at least the surface facing the major axis direction and the outer peripheral surface of the wiring and pipe material 11A. This surplus length portion 106 is a non-contact portion of the inner peripheral surface of the holding portion 101 that does not contact the outer peripheral surface of the wiring and pipe material 11. That is, the wiring and pipe material fixture 100 firmly sandwiches the outer peripheral surface of the wiring and pipe material 11A with the pressure contact portions 105 facing each other in the minor axis direction. Since the inner space 103 has a substantially elliptical shape and the outer diameter of the wiring and pipe material 11A is the same as the length of the minor axis S, the wiring and pipe material 11A is restricted from escaping into the gap on the surplus length portion 106 side. Therefore, in this installation structure, the wiring and pipe material 11A with the reference diameter is stably held and fixed with respect to the installation surface.

[0039] FIG. 8 is a schematic diagram illustrating a series of steps of holding a wiring and pipe material 11A with a reference diameter by a wiring and pipe material fixture 100. As shown in FIG. 8(a), the holding portion 101 is bent and deformed so as to expand the opening portion 104, and the wiring and pipe material 11A is passed through the opening portion 104 and introduced into the inner space 103 of the holding portion 101. Next, the wiring and pipe material 11A is moved to approximately the center of the inner space 103. Next, as shown in FIG. 8(b), the tip of the second extended portion 116 is pressed toward the first extended portion 111, and the hanging claw 118 is engaged with one of the locking teeth of the locking tooth row 115. At this time, the hanging claw 118 engages with the locking tooth row 115 at the initial position in the extending direction in the original shape. In other words, in this step, it is not necessary to slide the second extended portion 116 with respect to the first extended portion 111 in the extending direction. At this time, the hanging claw 118 is locked to the locking tooth row 115, and movement toward the tip side in the extending direction is restricted. Then, as shown in FIG. 8(c), by abutting and overlapping the opposing overlapping surfaces of the first extended portion 111 and the second extended portion 116, the opening portion 104 is completely closed, and the wiring and pipe material 11A can be held by being sandwiched by the pressing portion 105 in the minor axis direction. In this state, the fixing surface 112 of the first extended portion 111 is aligned with a predetermined position on the installation surface, and the screw 15 is driven into the communicating first fixing hole 113 and second fixing hole 117, whereby the wiring and pipe material fixture 100 can be fixed to the installation surface, and the first installation structure can be constructed.

[0040] FIG. 9 is a schematic cross-sectional view of a second installation structure in which a wiring and pipe material 11B with a corresponding maximum diameter selected from a corresponding group of wirings and pipe materials is disposed on an installation surface by a wiring and pipe material fixture 100. Here, the outer diameter of the wiring and pipe material 11B is larger than the distance between the inner surfaces of the holding portion 101 facing each other in the minor axis direction in the original shape of the holding portion 101. As shown in FIG. 9, with the inner peripheral surface of the holding portion 101 surrounding the outer periphery of the wiring and pipe material 11B, the first extended portion 111 and the second extended portion 116 are overlapped with each other and fixed to the structure with screws 15 through the first fixing hole 113 and the second fixing hole 117. At this time, the hanging claw 118 has moved from the initial position in the extending direction in the original shape to the relative position on the tip side and is engaged with the most distal locking tooth of the locking tooth row 115.

[0041] Further, the inner peripheral surface of the holding portion 101 has a substantially circular shape along the outer peripheral surface of the wiring and pipe material 11B. The center of the wiring and pipe material 11B is located at substantially the center of the inner space 103 of the holding portion 101, and most of the inner surface of the inner peripheral surface of the holding portion 101 is in pressure contact with the outer peripheral surface of the wiring and pipe material 11B. Here, while a pressure contact portion 105 that is in pressure contact with the outer peripheral surface of the wiring and pipe material 11B is formed in most of the inner peripheral surface of the holding portion 101, the formation of a surplus length portion 106 that does not contact the outer peripheral surface of the wiring and pipe material 11B is suppressed. That is, the wiring and pipe material fixture 100 firmly sandwiches the outer peripheral surface of the wiring and pipe material 11B at least with the opposing pressure contact portions 105. Therefore, in this installation structure, the wiring and pipe material 11B having the corresponding maximum diameter is stably held and fixed with respect to the installation surface.

[0042] FIG. 10 is a schematic diagram illustrating a series of steps of holding the wiring and pipe material 11B having the corresponding maximum diameter with the wiring and pipe material fixture 100. As shown in FIG. 10(a), the holding portion 101 is bent and deformed so as to expand the opening portion 104, and the wiring and pipe material 11B is passed through the opening portion 104 and introduced into the inner space 103 of the holding portion 101. At this time, as shown in FIG. 10(b), the belt-shaped holding portion 101 elastically deforms from the substantially elliptical original shape along the outer periphery of the wiring and pipe material 11B. Due to the elastic deformation of the holding portion 101, the second extended portion 116 is separated from the first extended portion 111, and the wiring and pipe material 11B is temporarily held by the holding portion 101 in a state where the opening portion 104 is more open than the original shape. Then, as shown in FIG. 10(c), by bringing the opposing overlapping surfaces of the first extended portion 111 and the second extended portion 116 into contact with each other and overlapping them, the opening portion 104 can be completely closed, and the wiring and pipe material 11B can be held by sandwiching it with the pressure contact portion 105. In this state, by aligning the fixing surface 112 of the first extended portion 111 with a predetermined position on the installation surface and driving screws 15 into the communicating first fixing hole 113 and second fixing hole 117, the wiring and pipe material fixture 100 can be fixed to the installation surface, and the second installation structure can be constructed.

[0043] FIG. 11 is a schematic cross-sectional view of a third installation structure in which a wiring and pipe material 11C having the minimum diameter corresponding to a corresponding wiring and pipe material group is disposed on an installation surface by a wiring and pipe material fixture 100. Here, the outer diameter of the wiring and pipe material 11C is smaller than the distance between the inner surfaces of the holding portions 101 facing each other in the minor axis direction in the original shape of the holding portion 101. As shown in FIG. 11, with the inner peripheral surface of the holding portion 101 surrounding the outer periphery of the wiring and pipe material 11C, the first extending portion 111 and the second extending portion 116 are overlapped with each other and fixed to the structure with screws 15 through the first fixing hole 113 and the second fixing hole 117. At this time, the hanging claw 118 has moved from the initial position in the extending direction in the original shape to the relative position on the proximal end side and is engaged with the most proximal locking tooth of the locking tooth row 115.

[0044] In addition, the substantially elliptical shape of the inner peripheral surface of the holding portion 101 is deformed into a substantially elliptical shape smaller than the original shape. In particular, the length of the minor axis S of the deformed substantially elliptical shape (the distance between the inner surfaces) is smaller than the length of the minor axis S of the original shape. Also, the circumferential length of the outer edge of the inner space 103 of the holding portion 101 is shorter than the original shape by the amount that the second extending portion 116 has moved to the proximal end side of the first extending portion 111. Furthermore, the inclination angle between the major axis L of the deformed substantially elliptical shape and the installation surface is smaller than the original shape. In particular, one end side portion of the holding portion 101 is pressed from above by the second extending portion 116, so that the outer surface near the one end side of the holding portion 101 is in contact with the installation surface. As a result, the outer surface of the holding portion 101 is supported from below by the structure, and the wiring and pipe material 11C is fixed more firmly to the structure. And the center of the wiring and pipe material 11C is located at the intersection of the major axis L and the minor axis S (of the deformed substantially elliptical shape), and the inner surfaces of the inner peripheral surface of the holding portion 101 that face each other in the minor axis direction are in pressure contact with the outer peripheral surface of the wiring and pipe material 11C. Here, on the inner peripheral surface of the holding portion 101, there are formed a pressure contact portion 105 that is in pressure contact with the wiring and pipe material 11C so as to sandwich it between the surfaces facing each other in the minor axis direction, and a surplus length portion 106 that forms a gap between at least the surface facing the major axis direction and the outer peripheral surface of the wiring and pipe material 11C. The range of the surplus length portion 106 is larger by making the outer diameter of the wiring and pipe material 11 smaller compared to the installation structure of FIG. 7. That is, the wiring and pipe material fixture 100 firmly sandwiches the outer peripheral surface of the wiring and pipe material 11C with the pressure contact portion 105 facing each other in the minor axis direction. And since the inner space 103 has a substantially elliptical shape and the outer diameter of the wiring and pipe material 11C is the same as the length of the minor axis S, the wiring and pipe material 11C is restricted from escaping into the gap on the surplus length portion 106 side. Therefore, in this installation structure, the wiring and pipe material 11C having the corresponding minimum diameter is stably held and fixed with respect to the installation surface.

[0045] FIG. 12 is a schematic diagram illustrating a series of steps for holding the wiring and pipe material 11C with the minimum diameter corresponding to the wiring and pipe material fixing tool 100. As shown in FIG. 12(a), the holding portion 101 is bent and deformed so as to expand the opening portion 104, and the wiring and pipe material 11C is passed through the opening portion 104 and introduced into the inner space 103 of the holding portion 101. Next, as shown in FIG. 12(b), the opposing overlapping surfaces of the first extending portion 111 and the second extending portion 116 are brought into contact with each other and overlapped to completely close the opening portion 104, and the hanging claw 118 is engaged with the locking tooth row 115 at the initial position in the extending direction in the original shape. At this time, since the inner peripheral surface of the holding portion 101 forms a substantially elliptical shape that is substantially the same as the original shape, the wiring and pipe material 11C is loosely inserted into the inner space 103. Then, as shown in FIG. 12(c), the second extending portion 116 is slid toward the proximal end side along the extending direction with respect to the first extending portion 111 until the hanging claw 118 is engaged with the locking tooth at the most proximal end side of the locking tooth row 115. Then, the holding portion 101 is deformed so as to narrow the facing distance between the inner surfaces of the holding portion 101 in the short axis direction while the major axis L tilts in the direction along the installation surface from the substantially elliptical shape before the initial elastic deformation. At this time, as the second extending portion 116 slides toward the proximal end side, a force in the extending direction is preferentially applied to the upper portion of the holding portion 101 (the portion relatively separated from the installation surface) through the other end of the holding portion 101, so that the holding portion 101 is deformed so that the major axis L falls toward the installation surface. Then, the lower portion of the one end side of the holding portion 101 receives a force from the second extending portion 116 and extends toward the installation surface. In other words, the curved portion of the lower portion of the holding portion 101 is partially stretched so as to be along the installation surface. As a result, the holding portion 101 is deformed so as to tilt with respect to the installation surface.

[0046] Also, in the state of Fig. 12(c), the engaging claw 118 is engaged with the locking tooth row 115, and the movement toward the tip side in the extending direction is restricted. By narrowing the facing distance between the inner surfaces of the holding portion 101 in the minor axis direction to the outer diameter of the wiring and pipe material 11C with the corresponding minimum diameter, the wiring and pipe material 11C can be arranged at approximately the center of the inner space 103, and the wiring and pipe material 11C can be held by sandwiching it with the pressing portion 105 from the minor axis direction. In this state, by applying the fixing surface 112 of the first extending portion 111 to the installation surface and driving screws 15 into the communicating first fixing hole 113 and second fixing hole 117, the wiring and pipe material fixture 100 can be fixed to the installation surface, and a third installation structure can be constructed.

[0047] As described above, the wiring and pipe material fixture 100 of the present embodiment corresponds to two or more types of wiring and pipe materials 11 having different outer diameters from the corresponding minimum diameter to the corresponding maximum diameter, can stably hold the wiring and pipe materials 11, and can be fixed to the installation surface of the structure. And the laying device 10 can select a wiring and pipe material 11 having a predetermined outer diameter within the range between the corresponding minimum diameter and the corresponding maximum diameter from the group of wiring and pipe materials, and can lay the wiring and pipe material 11 with respect to the structure.

[0048] Hereinafter, the effects of the wiring and pipe material fixture 100 in an embodiment of the fixture according to the present invention will be described.

[0049] According to the wiring and pipe fixture 100 of the present embodiment, the inner peripheral surface of the holding portion 101 forms a substantially elliptical shape having a major axis L and a minor axis S in its original shape, and one end of the major axis L is closer to the opening portion 104 than both ends of the minor axis S. The wiring and pipe fixture 100 can arrange the wiring and pipe material 11 in the substantially elliptical inner space 103 of the holding portion 101 in its original shape and sandwich the wiring and pipe material 11 between the inner surfaces facing each other in the minor axis direction. In particular, when the hanging claw 118 moves relative to the proximal end side (one side in the extending direction) of the locking tooth row 115 and is locked, the holding portion 101 deforms so as to form a substantially elliptical shape having a minor axis S smaller than its original shape. Thereby, when holding the wiring and pipe material 11 with a smaller diameter, the holding portion 101 can firmly sandwich the outer peripheral surface of the wiring and pipe material 11 between the inner surfaces facing each other in the minor axis direction within the inner space 103 having a smaller substantially elliptical shape. Therefore, the wiring and pipe fixture 100 of the present embodiment can more stably hold and fix the wiring and pipe material 11 with a smaller diameter among at least two types of wiring and pipe materials.

[0050] Furthermore, the wiring and pipe fixture 100 of the present embodiment can exhibit several advantageous effects compared to the conventional (Patent Document 1) wiring and pipe fixture.

[0051] First, in the wiring and pipe fixture of Patent Document 1, in its original shape, a hanging claw-shaped locking portion is located at the tip, and the locking portion is configured to engage with the tip of a saw blade-shaped locked portion. Therefore, it is cited as a problem that it does not correspond to wiring and pipe materials with a larger diameter than the inner diameter of the original belt. On the other hand, in the wiring and pipe fixture 100 of the present embodiment, the hanging claw 118 can move to both the tip side and the proximal end side in the extending direction and engage with the locking tooth row 115, and the inner space 103 of the holding portion 101 can be deformed so as to expand and contract according to the outer diameter of the wiring and pipe material 11. Therefore, the wiring and pipe fixture 100 can correspond to wiring and pipe materials with larger and smaller diameters with respect to the wiring and pipe material with the reference diameter corresponding to its original shape.

[0052] Second, in the wiring and pipe fixture of Patent Document 1, when holding a wiring or pipe material with a smaller diameter than the inner diameter of the original-shaped band, the hook-shaped locking portion moves to the proximal end side (band side) of the serrated engaged portion and locks. At this time, while the band substantially maintains a circular shape, it deforms to follow the outer circumference of the wiring or pipe material. Therefore, approximately, it is necessary to slide the hook-shaped locking portion to the proximal end side by the amount obtained by subtracting the outer circumference of the wiring or pipe material with a smaller diameter from the circumference of the original-shaped band. The smaller the outer diameter of the wiring or pipe material to be held, the more prominent this movement amount becomes, and it is cited as a problem that the unnecessary serrated engaged portion is exposed for a long time and the appearance deteriorates. On the other hand, in the wiring and pipe fixture 100 of the present embodiment, when the hook 118 is moved to the proximal end side of the locking tooth row 115, the facing distance of the inner surface in the minor axis direction of the holding portion 101 decreases, and the holding portion 101 deforms so that the portion occupied by the surplus portion 106 that does not contact the outer peripheral surface of the wiring or pipe material 11 with a smaller diameter increases. That is, the wiring and pipe fixture 100 holds the wiring or pipe material 11 by forming the surplus portion 106 and narrowing the substantially elliptical holding portion 101 in the minor axis direction according to the outer diameter of the wiring or pipe material 11 without following the inner peripheral surface of the holding portion 101 to the outer circumference of the wiring or pipe material 11. Therefore, the wiring and pipe fixture 100 can effectively reduce the movement amount of the hook 118 with respect to the change (decrease) in the outer diameter of the wiring or pipe material compared to the wiring and pipe fixture of Patent Document 1. As a result, the wiring and pipe fixture 100 of the present embodiment can also be compatible with wiring and pipe materials with a smaller diameter, and by reducing the movement amount, the exposure amount of the locking tooth row 115 can be effectively reduced, and its appearance can also be improved.

[0053] [Modification Example] The present invention is not limited to the above embodiment and can take various modification examples. Hereinafter, modification examples of the present invention will be described. In each modification example, components in which the lower two digits are common among the components indicated by three digits have the same or similar features and the description thereof will be partially omitted unless otherwise explained.

[0054] (1) The wiring and pipe fixture of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe fixture of the above embodiment, the first extended portion is configured to have a fixed surface, but the present invention is not limited thereto. FIG. 13 is a schematic cross-sectional view of a wiring and pipe fixture 200 according to a modified example of the present invention. The wiring and pipe fixture 200 includes a holding portion 201 extending in a strip shape from one end to the other end, a first extended portion 211 formed at one end of the holding portion 201 and extending in a direction away from the holding portion 201, a locking tooth row 215 formed on the first extended portion 211, a second extended portion 202 formed at the other end of the holding portion 201, a hanging claw 218 formed on the second extended portion 202, and fixing portions (a first fixing hole 213 and a second fixing hole 217) for fixing to a structure. In the wiring and pipe fixture 200, a fixed surface 219 is provided on the bottom surface of the second extended portion 216. Further, each locking tooth of the locking tooth row 215 and the hanging claw 218 form rectangular protrusions (or concavo-convex shapes) that can mesh with each other, different from the above embodiment. That is, the locking tooth row 215 and the hanging claw 218 are locked to each other in both directions of the extending direction, and relative sliding in both directions is restricted. In this case, the adjustment of the overlapping position of the first extended portion 211 and the second extended portion 216 is performed in a state where the hanging claw 218 is separated from the locking tooth row 215. Alternatively, although not shown, each locking tooth of the locking tooth row and the hanging claw may be symmetric triangular protrusions. In this case, the locking tooth row and the hanging claw allow relative sliding in both extending directions by relaxing the force pressing the overlapping surfaces of the first extended portion and the second extended portion, but under a certain pressing force or in a state fixed through the fixing portion, a locking state in the extending direction is formed between the locking tooth row (locking portion) and the hanging claw (locked portion), and functions to maintain the overlapping position of the first extended portion and the second extended portion. Similarly, in the wiring and pipe fixture 200 of this embodiment, when the hanging claw 218 as the locked portion relatively moves to the tip side (one side in the extending direction) of the locking tooth row 215 as the locking portion and is locked, the inner peripheral surface of the holding portion 201 deforms to form a substantially elliptical shape having a minor axis smaller than the original shape.

[0055] (2) The wiring and pipe fixture of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe fixture of the above embodiment, the holding part, the first extended part, and the second extended part are integrally formed of synthetic resin, but they may be a combination of separate bodies. Further, the holding part may be formed of a thin metal plate.

[0056] (3) The wiring and pipe fixture of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe fixture of the above embodiment, the engaged part can move to both the tip side and the base end side in the extending direction and engage with the engaging part, and the inner space of the holding part can be deformed so as to expand and contract according to the outer diameter of the wiring and pipe. However, the present invention is not limited to the above form. In the original shape, the tip of the first extended part (engaging part) and the tip of the second extended part (engaged part) may be arranged at the same position in the extending direction. In this case, it is not possible to hold a wiring and pipe having a diameter larger than the reference diameter, but it is possible to stably hold a wiring and pipe having a smaller diameter in the same manner as the above embodiment.

[0057] (4) The wiring and pipe fixture of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe fixture of the above embodiment, the engaging part and the engaged part are composed of a combination of an engaging tooth row and a hanging claw, but the present invention is not limited thereto. For example, the wiring and pipe fixture 300 shown in FIG. 14 includes a first engaging tooth row 315 as an engaging part and a second engaging tooth row 318 as an engaged part. Alternatively, one of the engaging part and the engaged part may be a pin, and the other may be a hole or a groove.

[0058] (5) The wiring and pipe fixture of the present invention is not limited to the configuration of the above embodiment. In the wiring and pipe fixture of the above embodiment, the major axis of the substantially elliptical shape of the holding part is configured to be inclined with respect to the fixing surface, but the present invention is not limited thereto, and the major axis may be perpendicular to the fixing surface.

[0059] (6) The wiring and pipe material fixture of the present invention is not limited to the configuration of the above-described embodiment. In the wiring and pipe material fixture of the above-described embodiment, when holding the wiring and pipe material with the maximum corresponding diameter, it was exemplified that the holding portion is deformed into a substantially circular shape and almost no surplus portion is formed on the inner peripheral surface of the holding portion. However, in the present invention, even when holding the wiring and pipe material with the maximum corresponding diameter, the shape of the holding portion may be determined so that a surplus portion remains on the inner peripheral surface of the holding portion.

[0060] The present invention is not limited to the above-described embodiment and modification examples, and can be implemented in various aspects as long as it belongs to the technical scope of the present invention.
