Description

[Technical field]

[0001] The present invention relates to a wiring / piping material support that is fixed to a support object such as a structure and has an internal space that can be divided so that wiring / piping materials can be stored separately. [Background technology]

[0002] Known wiring / piping material supports used for the above purpose are disclosed in Patent Documents 1 and 2. In Patent Document 1, a partition portion 12 that partially divides the internal space is provided as an integral part, and in Patent Document 2, an erected piece 50 that divides the internal section into roughly two parts is provided as an integral part, making it possible to separately accommodate different types of wiring / piping material.

[0003] Therefore, in both Patent Documents 1 and 2, the presence of the partition portion 12 or the standing piece 50 that is integrally formed with the wiring / piping material support narrows the internal space, and although the partition portion 12 or the standing piece 50 is not necessary when accommodating only a single wiring / piping material, their presence also impedes the accommodation work.

[0004] [Patent Document 1] JP 2013-87907 A [Patent Document 2] JP 2015-80395 A Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has an objective of providing a wiring / piping support that allows the internal space to be partitioned only when partitioning is required, without narrowing the internal space when partitioning is not required. [Means for solving the problem]

[0006] The invention of claim 1 to solve the above problem is as follows: A wiring / piping material support device that has a support part for supporting wiring / piping material and is fixed to a fixed object such as a structure, the support portion includes a partition wall that separates an inside portion for housing and supporting the wiring / piping material from an outside portion, an internal space defined by the partition wall, an opening portion formed by removing a portion of the partition wall to communicate the internal space with the outside, and a support arm portion whose base end side is connected to the partition wall by a connecting portion, The support arm is characterized in that it can rotate around the base end as an axis to move from a retracted position in which it is retracted from the internal space to a protruding position in which the tip end protrudes into the internal space, thereby dividing the internal space.

[0007] According to the invention of claim 1, the supporting arm can move from a retracted position in which it is retracted from the internal space to a protruding position in which its tip protrudes into the internal space to divide the internal space, so that the supporting arm protrudes into the internal space only when it is necessary to divide the internal space, and wiring and piping materials can be stored separately in each internal space divided by the supporting arm. Therefore, when the supporting arm is in the retracted position, the internal space is not narrowed by the presence of the supporting arm, so that the internal space can be freely used to store and support wiring and piping materials. In addition, by using the support arm in a protruding position to divide the internal space into a front side and a back side when viewed from the opening, the entry of wiring and piping materials into the back side is restricted, and it is possible to prevent wiring and piping materials from being mistakenly arranged at the back side after the support arm has protruded into the internal space.

[0008] The invention of claim 2 is the invention of claim 1, wherein, in a state where the support arm portion in the protruding position and a part of the partition wall located below the support arm portion are fixed to the object to be fixed, the support arm portion is disposed with a predetermined distance therebetween in the up-down direction, The upper surface of the supporting arm and an upper surface of a part of the partition wall form a supporting surface that supports the wiring / piping material from below.

[0009] According to the invention of claim 2, the internal space is divided into upper and lower halves by the support arm, and separate wiring and piping paths are formed in each section. Regarding the installation and support of wiring and piping, when the support arm is in the retracted state, wiring and piping is accommodated in the internal space from the opening and supported by the upper surface of a part of the partition wall, and then the support arm is protruded, and another wiring and piping is accommodated in the internal space from the opening and supported by the support arm, so that the wiring and piping can be easily separated and accommodated.

[0010] The invention of claim 3 is the invention of claim 1, wherein the supporting arm portion in a protruding position is arranged horizontally, and the wiring / piping material is moved downward through the opening, thereby making it possible to support the wiring / piping material in two stages, upper and lower; The support arm in a protruding position is arranged vertically, and by moving the wiring / piping material downward through the opening, it is possible to move the wiring / piping material downward through the opening, thereby providing two types of support modes: a first support mode in which the wiring / piping material can be supported separately in two left and right rows in each of the internal spaces on both sides isolated by the support arm, and a second support mode in which the wiring / piping material can be supported separately in two left and right rows in each of the internal spaces on both sides isolated by the support arm.

[0011] According to the invention of claim 3, the same wiring / piping material support device can store and support the wiring / piping material in a separated state by selecting from two different support modes: a top-bottom two-tier support mode in which the device is arranged vertically and the support arms in a protruding position are arranged horizontally, and a left-right two-row support mode in which the device is arranged horizontally and the support arms in a protruding position are arranged vertically.

[0012] The invention of claim 4 is the invention of claim 1, characterized in that the supporting arm portion extends along the partition wall in the retracted position.

[0013] According to the invention of claim 4, the support arm extends along the partition wall in the retracted position, and is provided as if integrated with the partition wall, so the support arm does not take up much space. This makes it easy to handle the wiring / piping material support, and the support arm does not get in the way of the fixing work when fixing the wiring / piping material support to the object. In addition, when the support arm is in the retracted position and not in use, it is surrounded by the surrounding partition wall, so there is no risk of breakage.

[0014] The invention of claim 5 is characterized in that in the invention of claim 4, the side portion of the supporting arm portion facing the internal space in the retracted position has a shape that follows the inner surface of the partition wall.

[0015] According to the invention of claim 5, in the retracted posture of the supporting arm, the entire supporting arm is retracted into the internal space, and there is no protruding part within the internal space, so that the internal space is not narrowed.

[0016] The invention of claim 6 is characterized in that, in any one of claims 1 to 5, when the tip of the support arm rotates from the retracted position to the protruding position while fixed to the fixed object, it comes into contact with the fixed object or the opposing inner surface of a partition wall arranged opposite the connecting portion, and any further rotation is restricted.

[0017] According to the invention of claim 6, when the supporting arm rotates from the retracted position to the protruding position and its tip contacts the object to be fixed or the opposing inner surface of the partition wall arranged opposite the connecting part, the protruding position of the supporting arm is maintained and further rotation is prevented. Since the tip of the supporting arm in the protruding position contacts the object to be fixed or the like, the supporting arm is in a double-end supported state and the load-bearing capacity is increased.

[0018] The invention of claim 7 is characterized in that, in any of the inventions of claims 1 to 5, the base end side of the support arm has a rotation control portion that abuts against the partition wall when the support arm is in the protruding position, thereby controlling further rotation of the support arm.

[0019] According to the invention of claim 7, the rotation restricting portion provided on the base end side of the supporting arm in the partition wall determines the rotation angle of the supporting arm in the protruding position, and further rotation can be effectively restricted.

[0020] The invention of claim 8 is characterized in that, in any of the inventions of claims 1 to 5, the support arm portion and the partition wall have a posture maintaining portion that engages with each other in the protruding posture of the support arm portion to maintain the protruding posture of the support arm portion.

[0021] According to the invention of claim 8, the presence of the posture maintaining portion enables the protruding posture of the supporting arm to be maintained without being twisted, so that the wiring / piping material can be stably supported.

[0022] The invention of claim 9 is characterized in that, in any one of claims 1 to 5, the support arm portion is provided in the middle of the width direction of the partition wall, which is the arrangement direction of the wiring and piping material.

[0023] According to the invention of claim 9, both the support balance of the wiring / piping material by the supporting arms and the arrangement balance of the supporting arms relative to the partition wall are good.

[0024] The invention of claim 10 is the invention of any one of claims 1 to 5, wherein a fixing part to be fixed to the object to be fixed is provided at one end in the longitudinal direction of the partition wall, and a pair of anti-pullout elastic pieces for preventing the wiring / piping material inserted into the internal space from being pulled out is formed at the other end of the partition wall in a V-shape when viewed from a direction perpendicular to the object to be fixed in a state where the anti-pullout elastic pieces are fixed to the object to be fixed so as to cross the opening, The support arm in the retracted position is characterized in that it is accommodated and disposed in the arm accommodating space between the left and right divided partition walls having the pair of elastic pieces formed at the tip ends thereof.

[0025] In the invention of claim 10, the wiring / piping material entering the interior through the opening comes into contact with the inner surfaces of a pair of anti-pullout elastic pieces arranged in a V-shape when viewed from the left and right sides, and the pair of anti-pullout elastic pieces elastically deform outward, widening the width of the opening (the distance between the surface of the object to be fixed and the pair of elastically deformed anti-pullout elastic pieces), and is inserted into the interior space through the opening, and when the wiring / piping material inserted into the interior space tries to slip out, the wiring / piping material comes into contact with the outer surfaces of the pair of anti-pullout elastic pieces, and the pair of anti-pullout elastic pieces are elastically deformed so as to approach each other, and when their tips come into contact, deformation beyond this is suppressed, so that the presence of the pair of anti-pullout elastic pieces prevents the wiring / piping material from slipping out to the outside. And, since the support arm is arranged in the arm accommodating space between the left and right divided partition wall parts having the pair of anti-pullout elastic pieces formed at their tips, the arrangement balance of the support arm along the width direction of the partition wall is good. Effect of the Invention

[0026] In the present invention, the support arm can move from a retracted position in which it is retracted from the internal space to a protruding position in which its tip protrudes into the internal space to divide the internal space, so that the support arm protrudes into the internal space only when it is necessary to divide the internal space, and wiring and piping materials can be stored separately in each internal space divided by the support arm. Therefore, when the support arm is in the retracted position, the internal space is not narrowed by the presence of the support arm, so that the internal space can be freely used to store and support wiring and piping materials. In addition, the support arm in the protruding position divides the internal space into a front side and a back side as viewed from the opening, so that the entry of wiring and piping materials to the back side is restricted, and it is possible to prevent wiring and piping materials from being mistakenly arranged on the back side after the support arm protrudes into the internal space.

[0028] The present invention will be described in more detail below with reference to the best examples. EXAMPLES

[0029] The wiring / piping material support S1 of the first embodiment is a resin injection-molded product, and as shown in Figures 1, 6 and 7, is fixed to a side wall W of a building, which is one of the structures, and is used to accommodate and support a portion of a cable C, which is one of the long wiring / piping materials arranged along the side wall W, thereby supporting the cable C at a predetermined interval. 1 to 8, the support portion 10 that supports the wiring / piping material support S1 has an overall shape of a wide U-shape in front view, and includes a partition wall 2 that partitions an internal space 1 that accommodates a cable C from the outside and supports the cable C when the wiring / piping material support S1 is fixed to the side wall W, a support arm A connected to the partition wall 2 so that the cable C can be in either a retracted or protruding position relative to the partition wall 2, and an opening 8 that is formed between a pair of anti-pullout elastic pieces 3 at the upper end (tip) of the support arm A and the side wall W when the wiring / piping material support S1 is fixed to the side wall W, for accommodating the cable C from the outside into the internal space 1. The partition wall 2 has a rectangular shape with a large slenderness ratio when viewed from a direction perpendicular to the side wall W when the wiring / piping material support S1 is fixed to the side wall W. A fixing plate portion 4 for fixing the wiring / piping material support S1 to the side wall surface W is provided continuously to the base end portion of the partition wall 2. With the wiring / piping material support S1 fixed to the side wall surface W, the partition wall 2 and the fixing plate portion 4 connected to one end portion of the partition wall 2 as a whole form a rectangular shape when viewed from a direction perpendicular to the side wall surface W.

[0030] The inner surface of the fixing plate portion 4 is a flat contact surface 4a that contacts the side wall surface W, 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 excluding 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 S1 is used by fixing it to, for example, a ceiling surface. The wiring / piping material support S1 is fixed to a side wall surface W via its fixing plate portion 4, and the inside and outside are partitioned by a partition wall 2, forming the internal space 1 for the cable C between the side wall surface W, and an opening 8 is formed between the tips of a pair of anti-pullout elastic pieces 3 and the side wall surface W for passing and accommodating the cable C 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 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 the horizontally disposed portion of the lower end of the partition wall plate portion 6, and the second support surface 7 is the inner surface of the vertically disposed portion of the partition wall plate portion 6.

[0031] The partition wall 2, which is rectangular and wide U-shaped when viewed from the front, 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 elastic pieces 3 to the fixed plate portion 4, except for the pair of anti-pullout elastic 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 elastic 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.

[0032] 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.

[0033] As shown in Figures 4(a) and (c), when viewed from the left and right side, that is, when the wiring / piping material support S1 is fixed to the side wall surface W, the pair of anti-pullout elastic pieces 3 have a V-shape when viewed from a direction perpendicular to the side wall surface W when fixed to the side wall surface W, so that the spacing between them gradually narrows from the outside to the inside of the internal space 1 of the partition wall 2. Also, the pair of anti-pullout elastic pieces 3 have an acute-angled triangular shape whose width gradually narrows from the base end to the tip end.

[0034] 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.

[0035] The supporting arm A is connected to the rear end of the connecting plate 16, which is integral with the partition wall 2, via a semi-cylindrical connecting fulcrum 25 formed at the base end of the base 24, and rotates about the connecting fulcrum 25 between a protruding position in which the supporting arm A protrudes into the internal space 1 and a retracted position in which the supporting arm A is accommodated in the arm accommodating space 15. The supporting arm A is composed of the base 24, which remains accommodated in the partition wall 2 even in the protruding position, and whose lower end surface is supported by the inclined support surface 21, and a cable support 26, whose cross section is arc-shaped and whose entirety protrudes into the internal space 1 in the protruding position. The overall shape of the base 24 and cable support 26 constituting the supporting arm A is irregular, and the cross section has a constant width (horizontal length) over the entire length, but the vertical length gradually varies along the longitudinal direction in accordance with the irregular shape. In any part of the supporting arm A, the cross section is rectangular, although the ratio of the vertical side to the horizontal side is different, and the recess 22 having a square cross section is formed on the back surface thereof, and the fitting protrusion 23 provided on the inclined support surface 21 of the partition wall 2 is fitted into the base end portion of the recess 22, thereby stabilizing the protruding position of the supporting arm A. Also, as shown in Fig. 6, 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 the shape of the surface of the supporting arm A opposite to the support surface of the cable support part 26 is determined so that there is no protruding portion 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.

[0036] The original shape of the connecting fulcrum 25 has a semi-ring-shaped cross section and a semi-cylindrical overall shape as shown in Fig. 6, and when the supporting arm A rotates about the connecting fulcrum 25 as a fulcrum and changes from the retracted position to the protruding position of the supporting arm A, the connecting fulcrum 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. For this reason, when it is no longer necessary for the supporting arm A to hold the cable C at the intermediate part in the height direction of the internal space 1 and the cable C is supported only by the lower first supporting surface 5, it is necessary to return the supporting arm A to the retracted position, but since the connecting fulcrum 25 has been forcibly deformed to become closer to a cylindrical shape against the semi-cylindrical shape, which is its original shape, the supporting arm A is easily returned to the retracted position by the elastic restoring force of the connecting fulcrum 25 trying to return to its original shape without retaining the deformation shape habit of the protruding position. In addition, in the present invention, it is not essential that the support arm A be capable of being returned to the retracted position; the support arm A may be configured to be irreversibly changed to the protruding position and broken off when not needed.

[0037] 6 and 7, in the protruding position of the supporting arm A, the tip of the arc-shaped cable support part 26 abuts against the side wall surface W of the building, restricting any further rotation. With this structure, when the cable C is supported by the cable support part 26, the cable support part 26 has a double-end support structure, and the load-bearing capacity is increased. As a result, while with a cantilever support structure, the rigidity of the cable support part 26 itself needs to be increased to increase the load-bearing capacity, this is no longer necessary, making it possible to reduce the cross section of the supporting arm A and also stabilizing the support state of the cable C compared to a cantilever support structure.

[0038] 6, in the protruding position of the supporting arm A, a connecting fulcrum part 25 having a semi-ring shape in cross section is integrally connected to the upper surface of the base end part of the base part 24 of the supporting arm A, and the lower corner part of the base end part of the base part 24 is in a state immediately before abutting against the upper surface of the connecting plate part 16 on the rear side of the partition wall 2. Therefore, in the protruding position of the supporting arm A, if the cable support part 26 does not abut against the side wall surface W of the building and the cable support part 26 has a cantilever support structure, the lower corner part abuts against the upper surface of the connecting plate part 16 and functions as a rotation restricting part 27 that restricts further rotation, and the supporting arm part A is restricted from further rotating in the same direction beyond the state where it abuts against the upper surface of the connecting plate part 16 on the rear side of the partition wall 2.

[0039] In addition, at the portion where the base 24 of the support arm A is connected along the longitudinal direction of the partition wall plate portion 6 that constitutes the partition wall 2, and at three locations in front of and behind that, a pair of binding wire hooks 31 (one on each side) for hooking a binding wire (not shown) when binding and fixing the pipes supported on the second support surface 7 are provided at predetermined intervals along the longitudinal direction of the partition wall 2, for a total of three sets.

[0040] In the fixing plate portion 4 of the partition wall 2, first fixing holes 32 used for fixing the wiring / piping material support S1 to a structure by driving wood screws with an electric screwdriver, and second fixing holes 34 equipped with cylindrical sleeves 33 for fixing the wiring / piping material support S1 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 S1 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.

[0041] The above-mentioned wiring / piping material support S1 is used to partially support a plurality of cables C arranged along a side wall surface W of a building as follows. First, the wiring / piping material support S1 is vertically arranged so that the opening 8 faces upward, and the wood screws 36 inserted into the first fixing holes 32 of the fixing plate portion 4 are screwed into the side wall surface W by an electric screwdriver to fix the wiring / piping material support S1 to the side wall surface W. Here, when the cables C are to be supported by both the lower first supporting surface 5 formed on the partition wall 2 and the supporting arm A, and when the cables C are to be supported only by the first supporting surface 5, the supporting arm A is in a retracted position as shown by the solid line in FIG. 6, and when the cables C are to be supported only by the supporting arm A, the supporting arm A is in a protruding position. The supporting arm A can be put into the protruding position either before or after the wiring / piping material support S1 is fixed to the side wall W, but putting it into the protruding position before fixing prevents forgetting to protrude the supporting arm A and ensures that the cable is supported by the supporting arm A in the protruding position. A piercing protrusion 4b is formed along the width direction on the contact surface 4a of the fixing plate 4, and when the wood screw 36 is driven in, the piercing protrusion 4b pierces the side wall W, preventing the wiring / piping material support S1 from shifting.

[0042] When the cable C is supported in two stages by both the support arm A and the first support surface 5 below it, the support arm A is in a retracted position as shown by a solid line in Fig. 6. In this state, as shown in Figs. 9(a) to (c), a gap formed between a pair of retaining elastic pieces 3 at the upper end of the wiring / piping material support S1 and the side wall surface W serves as an opening 8 for inserting the cable C into the internal space 1 of the wiring / piping material support S1. When the cable C reaches the opening 8 and comes into contact with the pair of retaining elastic pieces 3, the pair of retaining elastic pieces 3 are arranged in a V-shape in side view so that the gap between them gradually narrows from the outside to the inside of the internal space 1. Therefore, the cable C comes into contact with each inner side of the pair of retaining elastic pieces 3, elastically deforming the pair of retaining elastic pieces 3 outward, thereby widening the width of the opening 8 and enabling the insertion of the cable C. After the cable C is inserted into the internal space 1 and becomes non-contact, the pair of anti-pullout elastic pieces 3 return to their original shape due to their elastic restoring force, thereby preventing the cable C, which has been housed in the internal space 1, from slipping out.

[0043] When the cable C inserted into the internal space attempts to slip out, the cable C comes into contact with the outer surfaces of a pair of anti-slip elastic pieces 3, and the pair of anti-slip elastic pieces 3 are elastically deformed to approach each other.When their tips come into contact, further deformation is suppressed, and therefore, the presence of the pair of anti-slip elastic pieces 3 prevents the cable C from slipping out to the outside.

[0044] As described above, after the required number of cables C (four in the illustrated example) are accommodated on the first support surface 5 below the partition wall 2, the support arm A in the retracted position is rotated into the internal space 1 around the connecting fulcrum 25 at the base end as a fulcrum to change to a protruding position, as shown in FIG. 7. In the protruding position of the support arm A, its tip end comes into contact (abuts) with the side wall surface W, and the support arm A has a double-end support structure, as described above. In this state, when another cable C is inserted into the internal space 1 from the opening 8 in the same manner as described above, the required number of cables C (two in the illustrated example) are supported by the support arm A in the protruding position. As a result, the multiple cables C are supported separately in two upper and lower tiers in the internal space 1 of the wiring / piping material support S1. Here, when the supporting arm A is in a protruding position and the internal space 1 of the wiring / piping material support S1 is divided into upper and lower halves, there is no risk of the cable C supported on the upper surface of the supporting arm A accidentally entering the internal space 1 below the supporting arm A, which has the advantage that the cable C can be reliably supported in two levels, above and below, relative to the internal space 1.

[0045] Furthermore, when the cable C is supported only by the first support surface 5 of the partition wall 2 without using the support arm A, the support arm A in the retracted position is completely retracted into the internal space 1 and there is no integral protrusion into the internal space 1, so that the internal space 1 maintains its maximum original storage space and there are no obstacles when storing the cable C in the internal space 1, so that the number of cables C that can be stored increases and the cable C can be stored smoothly in the internal space 1.

[0046] In the wiring / piping material support S1 of the above-mentioned embodiment 1, the supporting arm A in the retracted position is accommodated and arranged in the arm accommodating space 15 between a pair of divided partition wall portions 14 formed in the partition wall 2, so that the arrangement of the supporting arm A along the width direction of the partition wall 2 is well balanced, the supporting arm A in the retracted position is protected by the divided partition wall portions 14 on both sides and there is little or no risk of damage, and there is also an advantage that a pair of anti-pullout elastic pieces 3 can be formed in a V-shape in left and right side views at the tips of the pair of left and right divided partition wall portions 14. However, in the present invention, the partition wall 2 may be divided in half in the width direction and the supporting arm A may be arranged on one side.

[0047] In the above example of use, the wiring / piping support S1 is fixed to the side wall W of a building and is capable of supporting the cables C in two rows, upper and lower, but it is also possible to fix it to the ceiling wall of a building and support the wiring / piping material on the second support surface 7 of the partition wall 2, so that the cables C can be supported in two separate rows, left and right, by the supporting arm A in an upright position. EXAMPLES

[0048] Next, the wiring / piping material support S2 of the second embodiment of the present invention shown in Fig. 10 and Fig. 11 will be described only in terms of the differences from the wiring / piping material support S1 of the first embodiment. The wiring / piping material support S1 can support the cables C in two rows, one above the other, whereas the wiring / piping material support S2 of the second embodiment can support the cables C arranged in two rows, one above the other. For this reason, the partition wall 2 of the wiring / piping material support S1 is L-shaped when viewed from the front, and the fixing plate part 4 is parallel to the part of the partition wall 2 where the supporting arm part A is arranged, and is arranged shifted by a predetermined length along a direction perpendicular to the fixing plate part 4. In contrast, the wiring / piping material support S2 has a configuration in which the part of the partition wall 2 where the supporting arm part A is arranged and parallel to the fixing plate part 4 is set as the partition wall 2', and the fixing plate part 42 is integrally provided perpendicular to the partition wall 2' via the curved connecting part 41 at the end of the partition wall 2' opposite to the pair of anti-pullout elastic pieces 3. When a wood screw 44 inserted through a fixing hole 43 of the fixing plate portion 42 is screwed into the side wall surface W, the partition wall 2' is arranged on the side wall surface W while maintaining the horizontal position.

[0049] For this reason, in the wiring / piping material support S2, the partition wall 2' is supported horizontally on the side wall surface W via the fixing plate portion 42, and by arranging the supporting arm portion A in an upright position as shown in Figs. 10(b) and 11(b), the internal space 1' above the partition wall 2' is divided into two rows, left and right, by the supporting arm portion A, and the upper surface of the partition wall 2' becomes the support surface for the cable C. The pair of anti-pullout elastic pieces 3, the curved connecting portion 41 and the lower end portion of the fixing plate portion 42 all function as part of the partition wall that forms the internal space 1'. In the wiring / piping material support S2, the entire upper portion of the partition wall 2' becomes a wide opening 8' that moves the cable C downward and supports it on the partition wall 2'.

[0050] In the above-mentioned first and second embodiments, the cable C is given as an example of the wiring / piping material to be supported, but other wiring / piping materials such as pipes can also be supported.

[0051] In addition, in Example 1, a pair of anti-pullout elastic pieces 3 is provided to prevent the cable C housed and supported in the internal space 1 from falling out, but in the present invention, it is not essential to provide a mechanism for preventing the wiring / piping material housed and supported in the internal space from falling out (the present invention can be established even if there is no anti-pullout mechanism).
