Description

[Technical Field]

[0001] The present invention relates to a wiring / piping material holding mechanism that holds wiring / piping material with a pair of holding pieces erected on a base, and to a protective cover. [Background technology]

[0002] Known examples of protective covers for wiring and piping materials having the above-described configuration are those described in Patent Documents 1 and 2. The cover disclosed in Patent Document 1 has a pair of holding pieces formed on the base of a base with a double-wall structure that has a deformation-permitting space in between, making it possible to hold multiple types of wiring and piping materials with different outer diameters with their axes aligned. This has resulted in the base being unnecessarily large compared to the size (outer diameter) of the wiring and piping materials, which has created a problem in that the storage space inside the protective cover cannot be used effectively.

[0003] The protective cover disclosed in Patent Document 2 has a base 1 of a base, a pair of auxiliary support pieces 17 that abut against the outer peripheral surface of the lower end of the wiring or piping material and elastically deform outward significantly depending on the shape of the lower outer peripheral surface of the wiring or piping material, and a pair of retaining pieces 11 that elastically deform outward slightly only at their upper ends and abut against the outer peripheral surface of the upper end of the wiring or piping material. When supporting multiple wiring or piping materials with different outer diameters, the pair of retaining pieces 11 do not deform significantly, but the pair of auxiliary support pieces 17 do deform significantly. While this allows for efficient use of the storage space inside the protective cover, the difference in outer diameter of the wiring or piping material causes the axial center position of larger-diameter wiring or piping materials to be significantly lower than that of smaller-diameter wiring or piping materials, resulting in a significant vertical change in the axial center position when stored. This results in the problem of needing to change the axial center position, or the support position of the wiring or piping material, at the cover joints that connect protective covers to each other.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-292174 [Patent Document 2] Patent Publication No. 2021-116864 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention aims to provide a wiring / piping material holding mechanism and protective cover that can align the axial center positions of multiple wiring / piping materials with different outer diameters and hold them, while also making effective use of the storage space. [Means for solving the problem]

[0006] The invention of claim 1 to solve the above problem is: A base and a pair of holding pieces that are erected with the base portion as a base end, and are arranged opposite to each other so that their tip sides come into contact with the outer peripheral surface of the upper part of the wiring / piping material arranged therebetween and can press the wiring / piping material downward; a biasing piece formed on the same side of the base as the pair of holding pieces, which comes into contact with a lower outer peripheral surface of the wiring / piping material received between the pair of holding pieces and biases the wiring / piping material upward; a wiring / piping material holding mechanism, in which the pair of holding pieces and the biasing piece cooperate to hold the wiring / piping material, In order to accommodate at least two types of wiring / piping materials with different outer diameters, when a wiring / piping material with a relatively small diameter is received, the tip ends of the pair of holding pieces and the pair of biasing pieces come into contact with the wiring / piping material to hold the wiring / piping material, When a wiring or piping material of a relatively large diameter is received, the tip portions of the pair of holding pieces are displaced upward and outward so that the tips are separated from each other from the position where the wiring or piping material of the small diameter is held, and the pair of urging pieces are displaced downward by the same amount of displacement of the pair of holding pieces, and the inner surfaces of the tip portions of the pair of holding pieces and the pair of urging pieces displaced downward press against and hold the wiring or piping material of the large diameter.

[0007] According to the invention of claim 1, when a large-diameter wiring or piping material is received, if the outer diameter of the wiring or piping material is gradually increased while the axial center position of the wiring or piping material remains unchanged, the pair of retaining pieces will displace the tips of the pair of retaining pieces upward and outward so that the tips are separated from each other, and the pair of biasing pieces will displace downward by the same amount of displacement as the pair of retaining pieces, and the large-diameter wiring or piping material will be held by the pair of retaining pieces and the pair of biasing pieces after displacement. In this way, the large-diameter wiring or piping material is held by the pair of retaining pieces and the pair of biasing pieces as both the pair of retaining pieces and the pair of biasing pieces undergo large elastic deformation, in other words, the holding space holding the small-diameter wiring or piping material is expanded to both sides and downward by the same amount of displacement, so that at least two types of wiring or piping material with different outer diameters can be held with their axial centers always aligned. Therefore, when connecting protective covers consisting of a base and a cover body equipped with the wiring / piping material holding mechanism of the invention of claim 1 using a cover joint, even if the outer diameter of the wiring / piping material changes, the protective covers can be connected to each other using the same cover joint. Here, the "aligned" axial positions refer to a state in which the axial centers of wiring / piping materials with different outer diameters are completely aligned or almost aligned.

[0008] The invention of claim 2 is as follows: A base and a pair of holding pieces that are erected with the base portion as a base end, and are arranged opposite to each other so that their tip sides come into contact with the outer peripheral surface of the upper part of the wiring / piping material arranged therebetween and can press the wiring / piping material downward; a biasing piece formed on the same side of the base as the pair of holding pieces, which comes into contact with a lower outer peripheral surface of the wiring / piping material received between the pair of holding pieces and biases the wiring / piping material upward; a wiring / piping material holding mechanism, in which the pair of holding pieces and the biasing piece cooperate to hold the wiring / piping material, In order to accommodate at least two types of wiring / piping materials with different outer diameters, when a wiring / piping material with a relatively small diameter is received, the tip ends of the pair of holding pieces and the pair of biasing pieces come into contact with the wiring / piping material to hold the wiring / piping material, When a wiring or piping material with a relatively large diameter is received, the pair of holding pieces move in a direction in which their tip ends move away from each other, with their base ends serving as the tilting axis, and the pair of urging pieces are displaced downward, so that the inner surfaces of the tip ends of the pair of holding pieces and the pair of urging pieces displaced downward press against and hold the large diameter wiring or piping material.

[0009] The invention of claim 2 provides a mechanism for holding wiring and piping materials with a pair of holding pieces and a pair of biasing pieces provided at a base, in which a tilting axis for tilting the pair of holding pieces outward is formed at the base end of the pair of holding pieces, thereby increasing the amount of displacement of the pair of holding pieces when a relatively large diameter wiring and piping material is received. This allows for less wasted space and more effective use of the storage space when the wiring and piping material is placed in the storage space of a protective cover comprising a base and a lid equipped with the wiring and piping material holding mechanism of the invention of claim 2. Similarly to the invention of claim 1, the shape of the holding space for small diameter wiring and piping materials is determined so that the amount of displacement of each holding piece and each biasing piece is a specific value in the case of large diameter wiring and piping materials, thereby enabling at least two types of wiring and piping materials with different outer diameters to be held with their axial positions always aligned.

[0010] The invention of claim 3 is as follows: A base and a pair of holding pieces that are erected with the base portion as a base end, and are arranged opposite to each other so that their tip sides come into contact with the outer peripheral surface of the upper part of the wiring / piping material arranged therebetween and can press the wiring / piping material downward; a biasing piece formed on the same side of the base as the pair of holding pieces, which comes into contact with a lower outer peripheral surface of the wiring / piping material received between the pair of holding pieces and biases the wiring / piping material upward; a wiring / piping material holding mechanism, in which the pair of holding pieces and the biasing piece cooperate to hold the wiring / piping material, The pair of holding pieces are provided with tilting axial portions at their base ends that allow the tips to be displaced from a position close to each other to a position farther apart by tilting, and are characterized in that the axial centers can be kept aligned regardless of which of at least two types of wiring / piping material with different outer diameters is supported.

[0011] According to the invention of claim 3, the pair of holding pieces are provided with tilting axes on their base ends that enable them to tilt so that their tip ends can be displaced from a position close to each other to a position where they are separated from each other, and when supporting wiring or piping material with a relatively large outer diameter, the pair of holding pieces are deformed so that their tip ends are displaced significantly outward, with the tilting axes serving as the tilting axes. Therefore, regardless of which of at least two types of wiring or piping material with different outer diameters is supported, the axes can be kept aligned. Therefore, when protective covers consisting of a base and a lid body equipped with the wiring or piping material holding mechanism of the invention of claim 3 are connected to each other using cover joints, even if the outer diameter of the wiring or piping material changes, the protective covers can be connected to each other using the same cover joint, and the storage space for the protective covers can be used effectively.

[0012] The invention of claim 4 is a long protective cover comprising a base and a lid body that forms a storage space for wiring and piping materials by assembling the lid body to the base, The wiring and piping material holding mechanism according to any one of claims 1 to 3 is provided in the accommodation space, with the base serving as a base.

[0013] According to the invention of claim 4, at least two types of wiring and piping materials with different outer diameters can be accommodated in the storage space of the protective cover with their axes aligned, and the generation of wasted space is reduced, making it possible to efficiently accommodate the wiring and piping materials in the storage space.Furthermore, even if the outer diameter of the wiring and piping materials changes, the same cover joints that connect the protective covers to each other can be used without being changed. [Effects of the Invention]

[0014] The present invention provides a holding mechanism that holds at least two types of wiring and piping materials with different outer diameters using a pair of holding pieces and a pair of biasing pieces erected on a base.When holding a large-diameter wiring and piping material, both the pair of holding pieces and the pair of biasing pieces undergo large elastic deformation.In other words, the holding space that holds the small-diameter wiring and piping material expands to both sides and downward by the same amount of displacement, and the large-diameter wiring and piping material is held by each of the holding pieces and each biasing piece, so that at least two types of wiring and piping materials with different outer diameters can be held with their axes aligned. [Brief explanation of the drawings]

[Figure 2] 1(a) and 1(b) are cross-sectional views of the lid body L and the base V that constitute the protective cover B, respectively. [Figure 3] 10(a) and 10(b) are cross-sectional views of a base V before and after a small-diameter piping material P1 is held on the base V, respectively. [Figure 4] 10 is a cross-sectional view showing a state in which a large diameter piping material P2 is held on a base V. FIG. [Figure 5] (a) and (b) are cross-sectional views showing that small-diameter and large-diameter piping materials P1 and P2 are housed and protected in the storage space K of the protective cover B with their axial positions C1 and C2 arranged in the same position. DETAILED DESCRIPTION OF THE INVENTION

[0016] The present invention will be described in more detail below with reference to examples. In Figures 1 to 4, a protective cover B accommodates and protects a plurality of types of resin piping materials P1, P2 with different outer diameters in an internal accommodation space K with their axial centers aligned, and is composed of a base V fixed to a structure and a lid L that covers the base V, with the characteristic feature of the present invention being present in the base V. The base V and the lid L are both extrusion-molded elongated resin products and have the same cross-sectional shape over their entire lengths.

[0017] The base V has a pair of holding pieces S erected at both widthwise ends of a plate-shaped base plate 1, and a pair of biasing pieces E erected inside the pair of holding pieces S. The pair of holding pieces S are configured such that a deformation holding piece 3 is connected to the tip end of a protruding plate portion 2 that protrudes obliquely upward from both widthwise ends of the base plate 1, with the deformation holding piece 3 tilted inward. The deformation holding piece 3 has a recess 9 of a predetermined width formed along its entire length on the inside of its base end. Therefore, when a force that deforms the deformation holding piece 3 outward acts from the inside of the deformation holding piece 3, the deformation of the protruding plate portion 2 is not permitted, and only the deformation holding piece 3 elastically deforms around the base end as a tilting axis A, allowing it to tilt. Each holding piece S tilts around the tilting axis A of its base end, and is dimensionally designed to maximize the displacement of its tip end. The opening between the tips of the pair of retaining pieces S forms a receiving opening 4 for receiving multiple piping materials P1, P2 with different outer diameters, and the width W of the receiving opening 4 is set narrower than the outer diameter D1 of the small-diameter piping material P1.

[0018] The pair of urging pieces E, which are erected inside the pair of holding pieces S on the base plate 1, are erected at a slight outward tilt relative to the perpendicular to the base plate 1, and the inner surface is formed as a continuous flat surface along the width direction, while the outer surface is formed as a gently stepped surface so that a recess is formed in a predetermined length portion of the base end, so that the predetermined length portion of the base end of the pair of urging pieces E is formed thin along the width direction and is structured to be elastically deformable outward. The tilting axis A of the pair of holding pieces S is formed at a position lower, closer to the base plate 1, than the upper ends of the pair of urging pieces E, and the pair of urging pieces E are not in contact with the protruding plate portions 2 and deformation holding portions 3 of the pair of holding pieces S when supporting a large-diameter piping material P2 (see Figure 4).

[0019] The standing shape of the pair of holding pieces S and the pair of urging pieces E on the base V is the same as when they are holding the small diameter piping material P1, as shown in Fig. 2(b). In other words, when the pair of holding pieces S and the pair of urging pieces E hold the small diameter piping material P1, these holding pieces S and urging pieces E are not deformed at all or almost not deformed from their original shapes.

[0020] The base plate main body 1a on which the pair of holding pieces S and the pair of urging pieces E of the base plate 1 are erected is positioned slightly higher than the base plate end portions 1b formed at both widthwise ends of the base plate 1 and abutting against a structure, and a recessed engaging portion 5 is formed between the base plate end portions 1b and the protruding plate portion 2 to engage with the engaging portion 14 of the cover L. A pair of positioning protrusions 6 having the same width as the pair of urging pieces E is formed on the underside of the base plate main body 1a, and the space between the pair of positioning protrusions 6 serves as a positioning recess 7 into which a positioning plate portion (not shown) protruding from the end portion of an accessory connecting cover (not shown) in the connecting direction is inserted to connect one of the bases V to connect the bases V to each other, thereby positioning the bases V in the widthwise direction. A recess 8 is formed continuously in the longitudinal direction at the center of the width of the base plate main body 1a to indicate this center portion. 1 and 2, a groove provided in the longitudinal direction of the deformation holding portion 3 of the holding piece S of the base V indicates a breaking groove 10 for breaking off and cutting off the deformation holding portion 3 by a predetermined length.

[0021] 1, 2 and 5, the lid body L has side plate portions 12 formed integrally with and facing both widthwise ends of the top plate portion 11, and the opening between the tip ends of each side plate portion 12 is an assembly opening 13 that enables the lid body L to be assembled integrally to the base V. On the inner surface of the tip end of each side plate portion 12, a locking portion 14 that locks onto the locked portion 5 of the base V is integrally formed so as to protrude inward.

[0022] When the lid body L is pressed against the base V with the piping material P1 or P2 held by the pair of holding pieces S and the pair of biasing pieces E of the base V, each side plate portion 12 of the lid body L is elastically deformed outward, and then each locking portion 14 of the lid body L is inserted and locked into each locked portion 5 of the base V, causing each side plate portion 12 to restore to its original shape, and the base V and the lid body L are assembled together to house and protect the piping material P1 (P2). Therefore, the space between the pair of holding pieces S of the base V and the internal space of the lid body L form a storage space K in which the piping material P1 (P2) is housed.

[0023] To accommodate and protect small-diameter piping material P1 using the protective cover B, as shown in Figure 3, when the piping material P1 is pushed into the receiving opening 4 of the base V, only the deforming holding portions 3 of the pair of holding pieces S tilt outward about the tilting axis A, widening the width W of the receiving opening 4, so that the small-diameter piping material P1 is accommodated between the pair of holding pieces S, and the piping material P1 is held by the pair of holding pieces S, which have restored their original shape, and the pair of urging pieces E, whose shape remains unchanged. In other words, the small-diameter piping material P1 is held by the pair of holding pieces S, which remain unchanged in their original shape, and the pair of urging pieces E, with the tips of the pair of holding pieces S abutting against the upper outer peripheral surface of the piping material P1 and the tips of the pair of urging pieces E abutting against the lower outer peripheral surface of the piping material P1. In this state, when the cover body L is placed over the base V, the small diameter piping material P1 is housed and protected in the housing space K of the protective cover B, as shown in FIG. 5(a).

[0024] The large-diameter piping material P2 is a resin pipe P2' having a smaller diameter than the small-diameter piping material P1, covered with a cylindrical insulating material 21, and the outer diameter of the cylindrical insulating material 21 is the outer diameter D2 of the piping material P2. To hold the large-diameter piping material P2 on the base V, as shown in FIG. 4, when the piping material P2 is pushed into the receiving opening 4 of the base V, only the deforming holding portion 3 of the pair of holding pieces S is tilted significantly outward about the tilting axis A, and the pair of biasing pieces E is also tilted significantly outward, so that the holding pieces S and the biasing pieces E maintain their tilted, deformed state and hold the large-diameter piping material P2. The deforming holding portion 3 of each holding piece S is elastically deformed until it becomes approximately perpendicular to the base 1, and is in elastic contact with the central outer periphery of the piping material P2 in the height direction, and the biasing pieces E are in elastic contact with the lower outer periphery of the piping material P2.

[0025] Here, the holding pieces S and the biasing pieces E are in elastic contact with the outer peripheral surface of the central portion and the outer peripheral surface of the lower portion of the large-diameter piping material P2, which has been elastically deformed, and biasing forces F1 and F2 act on the piping material P2. The biasing forces F1 and F2 act substantially toward the axis C2 of the piping material P2. The holding pieces S and the biasing pieces E are elastically deformed so that the holding space holding the small-diameter piping material P1 expands to both sides and downward by the same amount of displacement, and the deformed state is maintained by the action of the biasing forces F1 and F2. Therefore, as shown in Figure 5, the position of the axis C1 of the small-diameter piping material P1 and the position of the axis C2 of the large-diameter piping material P2 held on the same base V can be aligned.

[0026] As shown in Figure 5(b), when the cover body L is placed over the base V holding the large-diameter piping material P2, the large-diameter piping material P2 is housed and protected in the storage space K of the protective cover B. When the large-diameter piping material P2 is housed and protected, the deformable holding portion 3 of each holding piece S of the base V is elastically deformed until it becomes almost perpendicular to the base portion 1 and is positioned close to the inner surface of each side plate portion 12 of the cover body L, and the top and bottom of the large-diameter piping material P2 housed in the storage space K abut against the top plate portion 11 of the cover body L and the base portion 1 of the base V, respectively, thereby maximizing the efficiency of the storage space K of the protective cover B. In Figure 5, H indicates various structures to which the base V of the protective cover B is fixed.

[0027] It is to be noted that the base V of the above embodiment can naturally hold a piping material having an intermediate outer diameter between the outer diameters D1 and D2 of the piping materials P1 and P2 having different outer diameters.

[0028] In the above embodiment, the biasing pieces that support the wiring and piping materials with different outer diameters from below are configured as a pair upright on the base plate 1, but a configuration in which only one Y-shaped biasing piece is upright at the middle of a pair of left and right holding pieces is also possible. Furthermore, the biasing piece does not necessarily have to be upright on the base plate 1, but can also be configured to extend laterally inward from the base ends of the pair of left and right holding pieces, and the laterally extending biasing piece can be tilted downward in accordance with the outer diameter of the wiring and piping materials to be supported.

[0029] In addition, the above embodiment is an example in which the wiring / piping material holding mechanism described in claims 1 to 3 is applied to a base that constitutes a protective cover for wiring / piping material, but it can also be applied to a saddle that holds wiring / piping material at multiple locations along its length and fixes it to a structure. Specifically, the saddle body that is fixed to the structure is equipped with a pair of holding pieces and a biasing piece specified in claims 1 to 3. [Explanation of symbols]
