Description

[Technical field]

[0001] The present invention relates to a wiring / piping support device that is fixed to a support object such as a structure and is capable of both widening the opening for inserting wiring / piping material into the support part and restricting the removal of the inserted wiring / piping material. [Background technology]

[0002] Patent Document 1 discloses a wiring / piping material support provided with an elastically deformable lid portion 127 that closes and opens an insertion opening O, on a support receiving portion 123 that supports wiring / piping material C. When the wiring / piping material C is inserted, the wiring / piping material C causes the lid portion 127 to elastically deform inside the support receiving portion 123 to form an insertion opening, and after the wiring / piping material C is inserted inside, the lid portion 127 returns to its original shape by its elastic restoring force, closing the insertion opening O and preventing the wiring / piping material C from slipping out.

[0003] In Patent Document 1, in order to open the insertion opening O, the lid portion 127 is elastically deformed into the support receiving portion 123, so if another wiring / piping material C is already supported within the deformation range of the support receiving portion 123, the free deformation of the support receiving portion 123 is hindered due to interference with the existing wiring / piping material C, preventing smooth insertion of the wiring / piping material C. To avoid this problem, it is necessary to enlarge the support receiving portion 123 of the wiring / piping material support, but this would result in the wiring / piping material support being unnecessarily large.

[0004] A plurality of flexible pieces 21, rectangular in side view, are supported in a cantilevered manner on the same plane with a small gap in the vertical direction on the inner surface of a vertically disposed plate-like protruding portion 14, and a plate-like base 12 is disposed facing the protruding portion 14 with a small gap 24 between it and the tip of each flexible piece 21. After a cable 41 is inserted obliquely into the gap 24 between the tip of the flexible piece 21 and the base 12, it is disposed horizontally and moved in a predetermined direction, whereby the tip of one or more flexible pieces 21 is bent in response to the movement of the cable 41 to provide resistance, thereby preventing the cable 41 from being pulled out.

[0005] The flexible piece 21 can be bent in any direction, and therefore cannot be used for the purpose of preventing the cable from coming loose only in a specific direction. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2013-87907 A [Patent Document 2] JP 2017-89828 A Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has an object to provide a wiring / piping support device that can both widen the opening for inserting wiring / piping material into the support part and regulate the removal of the inserted wiring / piping material, without having to secure a large movement space within the support part. [Means for solving the problem]

[0008] The invention of claim 1 to solve the above problem is as follows: A wiring / piping material support having a fixing part for fixing to a fixed object such as a structure and a support part for supporting the wiring / piping material from below, the support portion includes a partition wall that defines an internal space in a fixed state in which the support portion is fixed to the object to be fixed, an opening portion that connects the internal space with the outside by removing a portion of the partition wall, and a pair of anti-pullout elastic pieces that extend toward the object to be fixed so as to cross the opening portion in the fixed state, The pair of anti-pullout elastic pieces are characterized in that, when viewed from a direction perpendicular to the object to be fixed in the fixed state, they are formed in a V-shape whose width gradually narrows from the outside to the inside of the internal space.

[0009] According to the invention of claim 1, the pair of anti-pullout elastic pieces are formed in a V-shape that gradually narrows from the outside to the inside of the internal space when viewed from a direction perpendicular to the fixed object while fixed to the fixed object, so that when the wiring / piping material tries to enter the internal space from the outside, the wiring / piping material presses the inner surface of the pair of anti-pullout elastic pieces, which are the widest, outward, so that the pair of anti-pullout elastic pieces are elastically deformed outward so as to move away from each other, and the opening between the pair of anti-pullout elastic pieces and the fixed object is widened. As a result, the wiring / piping material enters the internal space of the wiring / piping material support through the widened opening and is supported. After the wiring / piping material enters, the pair of anti-pullout elastic pieces return to their original shape by their own elastic restoring force, and the opening returns to its original width, which does not allow the wiring / piping material to pass through, preventing the wiring / piping material from passing from the inside to the outside of the internal space.

[0010] On the other hand, if the wiring / piping material inserted and supported in the internal space tries to slip out through the opening for some reason and the pair of anti-pullout elastic pieces are pressed from the side of the internal space, the wiring / piping material will press the outer surfaces of the pair of anti-pullout elastic pieces inward, causing the pair of anti-pullout elastic pieces to elastically deform inward so that they approach each other and their tips come into contact with each other. Since normal pressing force prevents elastic deformation beyond this, the opening is only slightly widened and not widened to the extent that it allows the wiring / piping material to pass through, and as a result, the wiring / piping material inserted and supported in the internal space can be prevented from slipping out.

[0011] The invention of claim 2 is characterized in that in the invention of claim 1, the pair of retaining elastic pieces are in the shape of an acute triangle whose width narrows toward the tip end.

[0012] According to the invention of claim 2, the tip portions of the pair of retaining elastic pieces are more easily elastically deformed than the base portions, so that the opening can be reliably widened by the pressure of the wiring / piping material from the outside.

[0013] The invention of claim 3 is as follows: A wiring / piping material support having a fixing part for fixing to a fixed object such as a structure and a support part for supporting the wiring / piping material from below, the support portion includes a partition wall that defines an internal space in a fixed state in which the support portion is fixed to the object to be fixed, an opening portion that connects the internal space with the outside by removing a portion of the partition wall, and a pair of anti-pullout elastic pieces that extend toward the object to be fixed so as to cross the opening portion in the fixed state, The pair of anti-pullout elastic pieces are arranged side by side on the partition wall with their tips being free ends, and when pressed by wiring or piping material entering the internal space from the outside, the tips elastically deform so as to move away from each other, widening the opening, thereby allowing the wiring or piping material to enter the internal space through the opening, and when pressed by wiring or piping material attempting to escape from the internal space to the outside, the tips elastically deform so as to move closer to each other, preventing any further elastic deformation, thereby preventing the wiring or piping material from falling out.

[0014] The invention of claim 3 is a description of the invention of claim 1 from an operational standpoint, and is substantially the same as the invention of claim 1. Effect of the Invention

[0015] According to the present invention, by providing a pair of anti-pullout elastic pieces which are formed in a V-shape so that their width gradually narrows from the outside to the inside of the internal space when viewed from a direction perpendicular to the object to be fixed in the fixed state, it is possible to prevent the wiring and piping materials from falling out from the inside of the internal space to the outside by elastic deformation of the pair of anti-pullout elastic pieces in different directions without widening the internal space.

[Figure 13] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] The present invention will be described in more detail below with reference to the best embodiment. The wiring / piping material support S is a resin injection molded product, and as shown in Figures 1, 11 and 12, is fixed to a ceiling wall W1 or a side wall W2 of a building, which is one of the structures, and is used to support a part of a long wiring / piping material such as a pipe body P or a cable C arranged along the ceiling wall W1 or the side wall W2, thereby supporting the wiring / piping material at a predetermined interval. 1 to 8, the support portion 10 for supporting the wiring / piping material has an overall shape of a wide U-shape in front view, and includes a partition wall 2 for partitioning an internal space 1 for accommodating wiring / piping material from the outside and supporting the wiring / piping material when the wiring / piping material support S is fixed to the ceiling wall W1 or side wall W2, a support arm portion A connected to the partition wall 2 so as to be able to select either a retracted position or a protruding position with respect to the partition wall 2, and an opening 8 formed between a pair of retaining elastic pieces 3 formed at one end of the partition wall 2 in the longitudinal direction and the ceiling wall W1 or side wall W2 when the wiring / piping material support S is fixed to the ceiling wall W1 or side wall W2, for inserting the wiring / piping material from the outside into the internal space 1 to accommodate it. The partition wall 2 has a rectangular shape with a large slenderness ratio when viewed from a direction perpendicular to the ceiling wall W1 or side wall W2 when the wiring / piping material support S is fixed to the ceiling wall W1 or side wall W2. A fixing plate portion 4 for fixing the wiring / piping material support S to the ceiling wall W1 or side wall W2 is provided continuously to the base end of the partition wall 2. When the wiring / piping material support S is fixed to the ceiling wall W1 or side wall W2, the partition wall 2 and the fixing plate portion 4 connected to the other end in the longitudinal direction of the partition wall 2 form a rectangular shape as a whole when viewed from a direction perpendicular to the ceiling wall W1 or side wall W2.

[0018] The inner surface of the fixing plate portion 4 is a flat contact surface 4a that contacts the wall surface of the ceiling wall W1 or the side wall W2, and the surface of the inner surface of the partition wall 2 that is connected to the contact surface 4a forms a first support surface 5 for the cable C that is formed perpendicular to the contact surface 4a. The first support surface 5 is formed so that its upper surface is slightly convex in cross section in order to stabilize the support of the cable C. The portion of the partition wall plate portion 6 that forms the inner surface of the partition wall 2 to which the base portion of the support arm A is connected is a bulging support portion 6a that bulges slightly inward relative to other portions in order to ensure the support force of the support arm A in the protruding position. 3 and 4(b), the inner surface of the partition wall plate portion 6 constituting the partition wall 2 has the first support surface 5 and the inner end surfaces of the pair of retaining elastic pieces 3 facing each other in parallel in a front view, and the inner surface of the partition wall plate portion 6 constituting the partition wall 2 except for the first support surface 5 and the pair of retaining elastic pieces 3 is a second support surface 7 formed in a flat shape except for the bulging support portion 6a, and the second support surface 7 is connected to the first support surface 5 and the inner end surfaces of the pair of retaining elastic pieces 3 via arc surfaces. The second support surface 7 supports the wiring / piping material when the wiring / piping material support S is used by fixing it to, for example, a ceiling wall W1. The wiring / piping support S is fixed to a ceiling wall W1 or a side wall W2 via its fixing plate portion 4, and the interior and exterior are partitioned by a partition wall 2, forming the internal space 1 for wiring / piping materials between the ceiling wall W1 or the side wall W2, and an opening 8 is formed between the tips of a pair of anti-pullout elastic pieces 3 and the ceiling wall W1 or the side wall W2 for passing wiring / piping materials from the outside into the internal space 1. Here, the partition wall plate portion 6 forms a portion facing the internal space 1 inside the partition wall 2, and is a plate-like portion that is L-shaped in a front view from the base ends of the pair of anti-pullout elastic pieces 3 to the fixing plate portion 4, and the first support surface 5 is formed by the upper surface of a portion of the partition wall plate portion 6 that is connected perpendicularly to the fixing plate portion 4, and the second support surface 7 is formed by the inner surface of a portion that is formed apart from the fixing plate portion 4 and parallel to the fixing plate portion 4.

[0019] The partition wall 2, which is rectangular in side view and wide U-shaped in front view, uses less material to reduce weight and ensures a predetermined bending rigidity in both the longitudinal and width directions, and on the rear side of the partition wall plate portion 6 constituting the partition wall 2, first to third wall plate portions 11, 12, 13 are formed at predetermined intervals along the width direction, and hollow portions are formed between the first to third wall plate portions 11, 12, 13. That is, the outermost first wall plate portion 11 is provided continuously from the base ends of the pair of anti-pullout resilient pieces 3 to the fixed plate portion 4, except for the pair of anti-pullout resilient pieces 3 at the tip portion, and inside the pair of first wall plate portions 11, second wall plate portions 12 are provided continuously from the base ends of the pair of anti-pullout resilient pieces 3 to the part just before the fixed plate portion 4, with a predetermined interval therebetween. From the pair of anti-pull-out elastic pieces 3 at the tip of the partition wall 2 to the bulging support portion 6a of the partition wall plate portion 6, the central portion in the widthwise direction of the partition wall plate portion 6 is removed by a predetermined width (the distance between a pair of second wall plate portions 12), so that a pair of left and right divided partition wall portions 14 are formed symmetrically, and the constant-width space between the pair of divided partition wall portions 14 forms an arm accommodating space 15 for the support arm portion A in the retracted position.

[0020] A connecting plate portion 16 (see Figs. 1 and 2(b)) that connects the base end of the supporting arm portion A to the partition wall 2 is formed at the same height as the pair of second wall plate portions 12 at the base end opposite the pair of anti-removal elastic pieces 3 in the arm portion accommodating space 15 of the supporting arm portion A. Between the connecting plate portion 16 and the pair of second wall plate portions 12 on the front side of the fixed plate portion 4, a third wall plate portion 13 is formed.

[0021] The tip portions of the pair of dividing partition wall portions 14 are each formed with a curved connecting portion 9 that is arc-shaped toward the internal space 1 in a front view, and the tip portion of each curved connecting portion 9 is formed with a stop elastic piece 3 facing the first support surface 5. The inner surface of each curved connecting portion 9 is formed on the same plane as the inner surface of the dividing partition wall portion 14, and the outer surface is formed with a tapered surface whose thickness rapidly decreases toward the tip, and since the pair of stop elastic pieces 3 are formed continuously at the tip portion of each curved connecting portion 9, the pair of stop elastic pieces 3 are thin enough to be elastically deformable. As shown in Figures 4(a) and (c), a pair of thin-walled anti-pullout elastic pieces 3 have a V-shape when fixed to the ceiling wall W1 or side wall W2 when viewed from both the left and right side, so that the distance between them gradually narrows from the outside to the inside of the internal space 1 of the partition wall 2. When viewed from a direction perpendicular to the ceiling wall W1 or side wall W2, the pair of thin-walled anti-pullout elastic pieces have an acute-angled triangular shape whose width gradually narrows from the base end to the tip end.

[0022] 3 and 6, an inclined support surface 21 (see Fig. 2(a) and Fig. 6) is formed on the inner surface of the portion where the connecting plate portion 16 is formed on the rear side of the partition wall 2 for supporting the base end of the supporting arm A in a protruding state with the base end connected to the rear side of the partition wall 2. That is, the inclined support surface 21 is connected to the arm accommodating space 15 and formed to have the same width as the arm accommodating space 15, and a fitting protrusion 23 is formed in the center of the width of the inclined support surface 21, which fits into a recess 22 with a rectangular cross section formed over the entire length of the center of the width of the rear side of the supporting arm A, thereby stabilizing the protruding position of the supporting arm A.

[0023] The supporting arm A is connected to the rear end of the connecting plate 16 integrally provided with the partition wall 2 via a semi-cylindrical connecting fulcrum 25 formed at the base end of its base 24, and rotates about the connecting fulcrum 25 between a protruding position in which it protrudes into the internal space 1 and a retracted position in which it is accommodated in the arm accommodating space 15. When the wiring / piping material support S is used by fixing it to the ceiling wall W1, the supporting arm A functions to separate the internal space 1 into left and right, and when the wiring / piping material support S is used by fixing it to the side wall W2, it functions to separate the internal space 1 into top and bottom and support the wiring / piping material arranged above.

[0024] The support arm A is composed of the base 24, the lower end surface of which is supported by the inclined support surface 21, and the wiring / piping material support portion 26, which is an arc-shaped cross section and projects into the internal space 1 as a whole in the protruding position, while remaining contained within the partition wall 2 even in the protruding position. The base 24 and the wiring / piping material support portion 26 constituting the support arm A have an irregular overall shape, and the width (horizontal length) of the cross section is constant over the entire length, but the vertical length gradually changes along the longitudinal direction in accordance with the irregular shape. The cross section of each part of the support arm A is rectangular, although the ratio of the vertical side to the horizontal side differs, and the recess 22, which has a square cross section, is formed on the back surface, and the fitting protrusion 23 provided on the inclined support surface 21 of the partition wall 2 is fitted into the base end of the recess 22, thereby stabilizing the protruding position of the support arm A. 6, the shape of the surface of the supporting arm A opposite to the supporting surface of the wiring / piping material supporting portion 26 is determined so that, in the retracted position of the supporting arm A, the entire supporting arm A is retracted from the internal space 1 of the partition wall 2 and no protruding portion is present into the internal space 1. That is, in the retracted position of the supporting arm A, the supporting arm A extends along the partition wall 2.

[0025] The original shape of the connecting fulcrum part 25 has a semi-ring-shaped cross section and a semi-cylindrical overall shape as shown in Fig. 6, and when the supporting arm part A rotates about the connecting fulcrum part 25 as a fulcrum and changes from the retracted position to the protruding position of the supporting arm part A, the connecting fulcrum part 25, which has a semi-cylindrical overall shape, is deformed to become closer to a cylindrical shape against its original shape as shown in Fig. 7. Therefore, when it is no longer necessary for the supporting arm part A to hold the internal space 1 separated into left and right or top and bottom, it is necessary to return the supporting arm part A to the retracted position, but since the connecting fulcrum part 25 has been forcibly deformed to become closer to a cylindrical shape against its original semi-cylindrical shape, the supporting arm part A is easily returned to the retracted position by the elastic restoring force of the connecting fulcrum part 25 trying to return to its original shape without retaining the deformation shape habit of the protruding position.

[0026] In the protruding position of the support arm A, as shown in Fig. 6 and Fig. 7, the tip of the arc-shaped wiring / piping material support part 26 abuts against the ceiling wall W1, so that rotation beyond this is restricted. With this structure, when the wiring / piping material support S is fixed to the side wall W2 and the wiring / piping material is supported by the wiring / piping material support part 26, the wiring / piping material support part 26 has a double-end support structure, which has the advantage of increasing the load resistance. As a result, in the cantilever support structure, the rigidity of the wiring / piping material support part 26 itself needs to be increased to increase the load resistance, but this is no longer necessary, and the cross section of the support arm A can be made smaller, and the support state of the wiring / piping material is more stable than in the cantilever support structure. Even when the wiring / piping material support S is fixed to the ceiling wall W1 and used, the tip of the support arm A that separates the internal space 1 into left and right parts contacts the ceiling wall W1, so there is the advantage that the upright position of the support arm A can be easily maintained.

[0027] 6, in the protruding position of the support arm A, a half-ring-shaped connecting fulcrum 25 in cross section is integrally connected to the upper surface of the base end of the base 24 of the support arm A, and the lower corner of the base end of the base 24 is in a state immediately before abutting against the upper surface of the connecting plate 16 on the back side of the partition wall 2. Therefore, in the protruding position of the support arm A, if the wiring / piping material support part 26 does not abut against the ceiling wall W1 or side wall W2 of the building and the wiring / piping material support part 26 has a cantilever support structure, the lower corner abuts against the upper surface of the connecting plate 16 and functions as a rotation restricting part 27 that restricts further rotation, and the support arm A is restricted from further rotating in the same direction beyond the state in which it abuts against the upper surface of the connecting plate 16 on the back side of the partition wall 2.

[0028] Further, at a portion where the base 24 of the support arm A is connected along the longitudinal direction of the partition wall plate portion 6 constituting the partition wall 2, and at three locations in front of and behind that portion, a pair of binding wire hooking devices 31 for hooking the binding wire 51 when binding and fixing the pipe body P supported on the second support surface 7 with the binding wire 51 are provided at a predetermined interval along the longitudinal direction of the partition wall 2. A stopper protrusion 31a for preventing the binding wire 51 from coming out is provided at the tip of the binding wire hooking device 31 toward the rear side of the partition wall 2 (the side opposite the second support surface 7).

[0029] In the fixing plate portion 4 of the partition wall 2, first fixing holes 32 used for fixing the wiring / piping material support S to a structure by driving wood screws 36 with an electric screwdriver, and second fixing holes 34 equipped with cylindrical sleeves 33 for fixing the wiring / piping material support S to a structure by driving nails into the structure with a nail gun are formed at predetermined intervals along the longitudinal direction of the partition wall 2, and either one is used depending on the structure to which the wiring / piping material support S is fixed. When the second fixing hole 34 is used, the cylindrical sleeve 33 is crushed and stored in the surrounding short cylindrical storage portion 35, and when not in use, it is left as it is.

[0030] Next, with reference to Figures 6, 7 and 9, the order of supporting a part of a pipe P by the wiring / piping material support S fixed to the ceiling wall W1 will be described. The wiring / piping material support S is fixed horizontally to the ceiling wall W1 by screwing the wood screws 36 inserted into the first fixing holes 32 of the fixing plate part 4 into the ceiling wall W1, and in the fixed state, an opening 8 for inserting (advancing) the pipe P into the internal space 1 is formed between the tips of the pair of anti-pullout elastic pieces 3 and the wall surface of the ceiling wall W1. When inserting the first pipe P, the support arm part A is in a retracted position (see Figure 6).

[0031] Here, when the wiring / piping material support S is fixed to the ceiling wall W1, the pair of anti-pullout elastic pieces 3 are formed in a V-shape that gradually narrows from the outside to the inside of the internal space 1 when viewed from a direction perpendicular to the ceiling wall W1, as shown in Fig. 9(a). Therefore, when a pipe body P is inserted from the outside into the internal space 1, as shown in Fig. 10(b), the pipe body P comes into contact with the pair of anti-pullout elastic pieces 3 and presses the inner surface of the widest pair of anti-pullout elastic pieces 3 outward, so that the pair of anti-pullout elastic pieces 3 are elastically deformed outward so as to move away from each other, and the opening 8 between the pair of anti-pullout elastic pieces 3 and the ceiling wall W1 is widened. As a result, the wiring / piping material is inserted into the internal space 1 of the wiring / piping material support S through the widened opening 8 [see Fig. 9(c)] and supported. After the pipe body P is inserted, the pair of anti-pullout elastic pieces 3 return to their original shape due to their own elastic restoring force, and the opening 8 returns to its original width, which does not allow the pipe body P to pass through, thereby preventing the pipe body P from passing from the inside to the outside of the internal space 1, as described below.

[0032] Next, before inserting the second pipe P, as shown in FIG. 7, the support arm A, which is accommodated in the arm accommodation space 15 of the partition wall 2 and in a retracted state, is rotated toward the internal space 1 around the connecting fulcrum 25 to be in an upright state. In the upright state of the support arm A, its tip is in contact with the wall surface of the ceiling wall W1, so that the upright state is reliably maintained. In this state, the pair of anti-pullout elastic pieces 3 are elastically deformed to widen the opening 8 in the internal space 1 separated to the left and right by the upright support arm A, and the second pipe P is inserted in the front part of the opening 8 in the internal space 1 separated to the left and right by the upright support arm A. As a result, the two pipes P are accommodated in the internal space 1 separated to the left and right by the upright support arm A, and both are supported by the second support surface 7 of the wiring / piping material support S. When the two pipe bodies P supported separately in the internal space 1 are bound and fixed to the partition wall 2 by the binding wire 51 hooked onto the nearest binding wire hook 31, the pipe bodies P are prevented from rolling while supported.

[0033] Here, as shown in Fig. 10(a), if the pipe P housed and supported in the internal space 1 on the near side of the opening 8 rolls or the like for some reason and comes into contact with the pair of anti-pullout elastic pieces 3 and tries to come out, and the pair of anti-pullout elastic pieces 3 are pressed from the side of the internal space 1, as shown in Fig. 10(b), the pipe P presses the outer surfaces of the pair of anti-pullout elastic pieces 3 inward, so that the pair of anti-pullout elastic pieces 3 are elastically deformed inward so as to approach each other, and their tips come into contact with each other, as shown in Fig. 10(c). Since the "normal pressing force" prevents elastic deformation exceeding this, the opening 8 is only slightly widened, and is not widened to the extent that the pipe P can pass through, and as a result, the pipe P inserted and supported in the internal space 1 can be prevented from coming out. In addition, the above-mentioned "normal pressing force" refers to the pressing force that acts when a natural external force acts on the pipe body P and causes it to move within the internal space 1, and is a concept that excludes intentional excessive pressing force intended for the purpose of removing the pipe body P itself.

[0034] In addition, if, after the pipe body P is supported by the wiring / piping material support S and piped, incorrect piping is discovered, in order to pull out (remove) the pipe body P related to the incorrect piping from the wiring / piping material support S, the ``excessive pressing force'' is applied to the pipe body P related to the incorrect piping from the inside to the outside of the internal space 1, so that the pair of anti-pullout elastic pieces 3 are elastically deformed inward and the tips of the narrow portions on the internal space 1 side come into contact, and then the contact portions are further elastically deformed, so that they are lifted upward (towards the curved connecting portion 9) and overlap each other, and at the same time, the portions of the pair of anti-pullout elastic pieces 3 other than the narrow portions are elastically deformed toward each other's backs, the opening 8 is widened, and the pipe body P inside the internal space 1 can be pulled out.

[0035] In addition, the above-mentioned example of supporting the pipe body P is an example in which the pipe body P is supported in two rows in a separated state in each of the internal spaces 1 divided into left and right halves by the protruding support arm portion A, but it is also possible to support only one pipe body P in the center of the internal space 1, as shown in Figure 11.

[0036] 12 and 13 show another example of use of the wiring / piping material support S. In this example, the wiring / piping material support S is fixed vertically to the side wall W2 of the building, and the support arm A is arranged in a protruding state in the internal space 1, with its tip contacting the side wall W2. A plurality of cables C inserted into the lower part of the support arm A in the internal space 1 is supported by the first support surface 5 arranged horizontally, and a plurality of cables C inserted above the support arm A is supported by the support arm A. In this way, when the wiring / piping material support S is vertically arranged and fixed to the side wall W2 of the building, the support arm A is made to protrude into the internal space 1, so that the plurality of cables C can be supported separately in two tiers, upper and lower, in the internal space 1. It is also possible to support the cables C only by the first support surface 5 with the support arm A in a retracted position, or to support the cables C only by the support arm A with the support arm A in a protruding state.

[0037] The cable C has a smaller cross-sectional size than the pipe body P, but when it is inserted into the internal space 1 of the wiring / piping material support S, like the pipe body P, a pair of anti-pullout elastic pieces 3 elastically deform outward (the degree of elastic deformation is smaller than that of the pipe body P), and the opening 8 is widened to an extent that the cable C can be inserted, and the cable C is contained and supported in the internal space.

[0038] In the above embodiment, the tips of the pair of retaining elastic pieces 3 are not in contact with the ceiling wall W1 or the side wall W2, and a predetermined gap is formed between them and the wall surface of the ceiling wall W1 or the side wall W2 to form the opening 8. However, when the wiring / piping material support S is fixed to the ceiling wall W1 or the side wall W2, the tips of the pair of retaining elastic pieces 3 may abut (contact) the wall surface of the ceiling wall W1 or the side wall W2, and when the wiring / piping material enters from the outside to the inside of the internal space 1, the pair of retaining elastic pieces 3 are elastically deformed, so that the tips are separated from the wall surface of the ceiling wall W1 or the side wall W2, forming the opening 8 that allows the wiring / piping material to enter.

[0039] The wiring / piping material that can be supported by the wiring / piping material support is not limited to the above-mentioned pipe body P and cable C, but may be other piping materials and wiring materials. [Explanation of symbols]

Claims

1. A wiring / piping material support having a fixing part for fixing to a fixed object such as a structure and a support part for supporting the wiring / piping material from below, the support portion includes a partition wall that defines an internal space in a fixed state in which the support portion is fixed to the object to be fixed, an opening portion that connects the internal space with the outside by removing a portion of the partition wall, and a pair of anti-pullout elastic pieces that extend toward the object to be fixed so as to cross the opening portion in the fixed state, A wiring / piping support device characterized in that the pair of anti-pullout elastic pieces are formed in a V-shape so that their width gradually narrows from the outside to the inside of the internal space when viewed from a direction perpendicular to the object to be fixed in the fixed state.

2. 2. The wiring / piping material support according to claim 1, wherein the pair of retaining elastic pieces are in the shape of an acute triangle narrowing in width toward a tip end thereof.

3. A wiring / piping material support having a fixing part for fixing to a fixed object such as a structure and a support part for supporting the wiring / piping material from below, the support portion includes a partition wall that defines an internal space in a fixed state in which the support portion is fixed to the object to be fixed, an opening portion that connects the internal space with the outside by removing a portion of the partition wall, and a pair of anti-pullout elastic pieces that extend toward the object to be fixed so as to cross the opening portion in the fixed state, The pair of anti-pullout elastic pieces are arranged side by side on the partition wall with their tips as free ends, and when pressed by wiring or piping material entering the internal space from the outside, the tip ends elastically deform so as to move away from each other and the opening is widened, thereby allowing the wiring or piping material to enter the internal space through the opening, and when pressed by wiring or piping material attempting to escape from the internal space to the outside, the tip ends elastically deform so as to move closer to each other, thereby preventing any elastic deformation beyond this level, thereby preventing the wiring or piping material from falling out.
