Description

[Technical Field]

[0001] The present invention relates to a cable holder and a wire / piping material holder for holding cables in ducts including lighting ducts. [Background technology]

[0002] In Patent Document 1, lighting fixtures 2 are attached in a suspended state to a duct 1, and the power cable that supplies power to the lighting fixtures 2 hangs down significantly directly below the duct 1. The power cable hanging down significantly directly below the duct 1 not only looks bad, but is also dangerous as it may get caught on objects moving directly below the duct.

[0003] In Patent Document 2, a hanging hook 1 is hung in a state where it hangs down significantly directly below a duct 2 to which an outlet, lighting fixture, display device, or hanging hook can be attached. The hanging hook 1 has a height dimension that is larger than the height dimension of the duct 2, so although it can function as a hanging hook 1, the appearance is significantly impaired.

[0018] The invention of claim 7 is characterized in that, in the invention of any one of claims 1 to 5, the holding portion is sized to fit within the height range of the side of the lighting duct, which is the dimension between the opening and its opposing portion, when in an arranged state.

[0019] According to the invention of claim 7, even if the bottom surface, which is the surface opposite to the opening of the lighting duct, is in contact with the ceiling surface, the cable holder can be attached to the lighting duct.

[0020] The invention of claim 8 is characterized in that, in the invention of any one of claims 1 to 5, it comprises an attachment body having the attachment portion and a holder having the holding portion, and the holder can be assembled to the attachment body in a state where it is attached to the lighting duct.

[0021] According to the invention of claim 8, after determining the attachment position of the cable holder relative to the longitudinal direction of the lighting duct and attaching the attachment body, it is possible to assemble the holder to the attachment body, thereby improving the efficiency of cable wiring work.

[0022] The invention of claim 9 is as follows: A wiring / piping material holder that is attached to a long body and has flanges extending toward each other at the tips of a pair of side walls that are erected from a bottom, and has an opening that faces the bottom between the tips of the flanges, An attachment body attached to the opening, and a holding body rotatably assembled to the attachment body and holding the wiring and pipe materials adjacent to the long body in a state where they are adjacent to each other.

Mode for Carrying Out the Invention

[0026] Hereinafter, the present invention will be described in more detail with reference to a plurality of preferred embodiments.

Example

[0027] As shown in FIGS. 1 and 2, a cable holder B for holding a cable C on the side portion of a writing duct D includes a mounting body A that is mounted by inserting a part thereof into the writing duct D from its insertion opening 74, and a holder H that is assembled in a state of being rotatably connected to the mounting body A and holds the cable C on the side portion of the writing duct D.

[0028] As shown in FIGS. 1 to 5, the writing duct D is a long body having the same cross-sectional shape over its entire length. One end portion (usually the upper end portion) in the width direction of a pair of side plate portions 71 facing each other at a predetermined interval is connected by a top plate portion 72, so that the side facing the top plate portion 72 is opened. At the other end portion (usually the lower end portion) in the width direction of each side plate portion 71 at the opened portion, a pair of engaged flange plate portions 73 have an opening width W between their tip portions 01It is integrally provided inside the insertion opening 74 (refer to Fig. 6) in a state parallel to the top plate portion 72 and facing inward. Inside the pair of locked flange plate portions 73, a pair of inner groove forming flange portions 75 are formed in parallel with the respective locked flange plate portions 73, and at the tip of each inner groove forming flange portion 75, power line arrangement grooves 76 for arranging power lines are respectively formed. On one of the pair of side plate portions 71, for example, when linearly connecting two lighting ducts D or T-connecting three lighting ducts D using a joint, in order to connect the polarities of the voltage side and the ground side of the two power lines so that they match, a polarity confirmation protrusion 71a for preventing misconnection of the polarities is slightly projected downward with respect to the locked flange plate portion 73. In Fig. 6, W 02 is the inner surface interval between the inner surfaces of the pair of side plate portions 71 arranged opposite to each other.

[0029] As shown in Figs. 6 to 9, the cable holder B is composed of a mounting body A attached to the opening side of the lighting duct D and a holding body H assembled in a state rotatably connected to the mounting body A for holding the cable C between the side plate portion 71 of the lighting duct D. Both the mounting body A and the holding body H are formed by injection molding of resin.

[0030] As shown in FIGS. 11 to 13, the attachment body A is a member in which a part of itself is inserted and disposed inside through the insertion opening 74 of the writing duct D and is locked and fixed to a pair of locked flange plate portions 73 of the writing duct D. A base portion 1 having a rectangular plate shape as a whole, an inner locking plate portion 2 and an outer locking plate portion 3 that lock to the pair of locked flange plate portions 73 of the writing duct D inside and outside are integrally provided at an interval corresponding to the plate thickness of the locked flange plate portion 73. The inner locking plate portion 2 and the outer locking plate portion 3 are connected by an extremely short columnar rotation shaft portion 4, and the outer locking plate portion 3 and the base portion 1 are connected by an extremely short cylindrical connection cylinder portion 5. The inner surface of the inner locking plate portion 2 is a sliding contact surface 2a that slidably contacts the inner surface of the locked flange plate portion 73 when attaching to the writing duct D. After the inner locking plate portion 2 is inserted into the inside through the insertion opening 74 of the writing duct D, it is rotated 90° to present a rectangular thick plate shape that can be locked to the pair of locked flange plate portions 73. The short side length W1 is slightly shorter than the opening width W of the insertion opening 74 of the writing duct D, and the long side length W2 is shorter than the inner surface interval W between the pair of side plate portions 71 of the writing duct D. Each corner portion along one diagonal direction of the rectangular inner locking plate portion 2 is a portion that precedes along the rotation direction when the attachment body A rotates with respect to the writing duct, and is largely rounded to avoid interference to form an interference avoidance chamfered portion 10. Each corner portion along the other diagonal direction is much smaller and rounded compared to the interference avoidance chamfered portion 10. 01 is slightly shorter, and the long side length W2 is shorter than the inner surface interval W between the pair of side plate portions 71 of the writing duct D. 02 Each corner portion along one diagonal direction of the rectangular inner locking plate portion 2 is a portion that precedes along the rotation direction when the attachment body A rotates with respect to the writing duct, and is largely rounded to avoid interference to form an interference avoidance chamfered portion 10. Each corner portion along the other diagonal direction is much smaller and rounded compared to the interference avoidance chamfered portion 10.

[0031] The outer locking plate portion 3 has an oval shape in plan view, and the dimension (width) W3 of its short side (see FIG. 12(c)) is the opening width W of the insertion opening 74. 01Larger (wider) than that, and its inner surface (the surface facing the inner locking plate portion 2) is a sliding contact surface 3a that slidably contacts the outer surface of each locked flange plate portion 73 of the writing duct D. On both sides of the rotation shaft portion 4 on the sliding contact surface 3a of the outer locking plate portion 3, when the entire attachment body A is rotated and locked to the pair of locked flange plate portions 73 of the writing duct D, in order to reduce the sliding contact resistance against the pair of locked flange plate portions 73 and facilitate the rotation operation, deformation grooves 6 for facilitating the outward deformation of the outer locking plate portion 3 are respectively formed along the short side direction.

[0032] The extremely short columnar rotation shaft portion 4 that connects the inner locking plate portion 2 and the outer locking plate portion 3 has a cross-sectional shape in which rounded portions 4a with large rounded surfaces are provided at the respective corner portions (the corner portions leading along the rotation direction of the inner locking plate portion 2) in the diagonal direction of one side with a substantially square cross-section, as shown in FIGS. 13(c) and (e). The reason for providing the rounded portion 4a on the rotation shaft portion 4 is to enable the rotation shaft portion 4 to be rotated without interfering with the inner end portions of the pair of locked flange plate portions 73 of the writing duct D in a state where the inner locking plate portion 2 and the rotation shaft portion 4 of the attachment body A are inserted into the insertion opening 74 of the writing duct D. The first width along the short side direction of the inner locking plate portion 2 of the rotation shaft portion 4 with a substantially square cross-section is the same as the width W1 in the short side direction of the inner locking plate portion 2, but the second width W4 along the long side direction of the inner locking plate portion 2 of the rotation shaft portion 4 is slightly wider (larger) than the first width W1, and moreover, is smaller than the opening width W of the insertion opening 74 of the writing duct D [W > W4 > W1]. For this reason, a step portion 4c is formed at the portion connecting to the surface constituting the second width W4 in the rounded portion 4a. On each surface constituting the second width W4 along the longitudinal direction of the writing duct D in the attached state of the rotation shaft portion 4 with a substantially square cross-section, anti-play ridges 4b that bite into the opposing inner end surfaces of the respective locked flange plate portions 73 are provided along the axial direction to prevent play during attachment. 01 is smaller than [W 01 > W4 > W1]. For this reason, a step portion 4c is formed at the portion connecting to the surface constituting the second width W4 in the rounded portion 4a. On each surface constituting the second width W4 along the longitudinal direction of the writing duct D in the attached state of the rotation shaft portion 4 with a substantially square cross-section, anti-play ridges 4b that bite into the opposing inner end surfaces of the respective locked flange plate portions 73 are provided along the axial direction to prevent play during attachment.

[0033] As shown in Fig. 9, a pair of elastically deformable mounting pieces 22, which are rotatably connected to the attachment body A with respect to the holder H, are inserted between the outer locking plate portion 3 and the base portion 1 so as to sandwich the connecting cylinder portion 5 of the attachment body A from both sides, whereby the attachment body A and the holder H are assembled in a rotatably connected state. In this assembled state, in order to prevent the attachment body A and the holder H from rotating relative to each other, a locking ridge 5a is formed on the connecting cylinder portion 5 of the attachment body A, which is inserted and locked into one of a pair of locking recesses 22b formed on the inner surface of the pair of mounting pieces 22 of the holder H.

[0034] The base portion 1 having a rectangular shape in plan view is configured such that the base upper plate portion 7 and the base lower plate portion 8 are connected by connecting short column portions 11 at each corner portion, and a base space 12 is formed between the two plate portions 7 and 8. The base upper plate portion 7 is square, while the base lower plate portion 8 is rectangular. End face openings 13a and 13b having different shapes are formed at portions of each side of the base portion 1 having a square shape in plan view. By inserting strings through each end face opening 13a and 13b and suspending them, various articles can be suspended from the lighting duct D via the strings and the cable holder B. Further, as shown in Figs. 11 and 13(a) and (b), bolt insertion holes 14 into which headed bolts can be inserted are formed through the inner locking plate portion 2, the rotation shaft portion 4, the outer locking plate portion 3, the connecting cylinder portion 5, the base upper plate portion 7, and the base lower plate portion 8. By inserting a headed bolt through the bolt insertion hole 14, various articles can be suspended from the lighting duct D via the headed bolt and the cable holder B. At the portion of the bolt insertion hole 14 where the head of the headed bolt is inserted, two types of head insertion hole portions 14a and 14b having different inner diameters are continuously formed according to the size of the head.

[0035] Next, with reference to FIGS. 1, 6, 8, 14, and 15, a holding body H that is assembled to the attachment body A and holds the cable C between the outer side surface of the side portion of the writing duct D will be described. In a state where the holding body H is assembled to the attachment body A, a rectangular substrate portion 21 having a large aspect ratio is provided, with the central portion in the longitudinal direction of the holding body H disposed between the outer locking plate portion 3 and the base upper plate portion 7 of the attachment body A. At the central portion in the longitudinal direction of the substrate portion 21, a pair of mounting pieces 22 disposed on both sides of the connecting cylinder portion 5 of the attachment body A are disposed on the same plane as the substrate portion 21 in a state of protruding greatly in one direction in the width direction of the substrate portion 21. When the pair of mounting pieces 22 are bisected along the protruding direction, a fitting hole 23 into which the connecting cylinder portion 5 is relatively fitted is formed in a form in which a part of the circumferential direction is missing in the portion on the base end side connected to the substrate portion 21. The tip side (free end side) of the pair of mounting pieces 22 with respect to the fitting hole 23 is elastically contacted with the outer peripheral surface of the connecting cylinder portion 5 when the holding body H is moved close to the connecting cylinder portion 5 from a direction perpendicular to the axis of the connecting cylinder portion 5 for assembly. After gradually expanding the entire pair of mounting pieces 22 and then restoring them to their original shape, it serves as a mounting guide piece portion 22a that relatively fits the connecting cylinder portion 5 into the fitting hole 23. In the portion of the pair of mounting pieces 22 corresponding to the fitting hole 23, a pair of anti-rotation recesses 22b are formed for regulating the relative rotation of the attachment body A and the holding body H and facilitating the insertion of the inner locking plate portion 2 of the attachment body A into the insertion opening 74 of the writing duct D by inserting the anti-rotation ridge 5a formed on the connecting cylinder portion 5. In the connecting protrusion portion 24 that integrally connects the pair of mounting pieces 22 to the substrate portion 21, a deep and easily deformable groove portion 25 is formed for facilitating the expansion of the pair of mounting pieces 22 along the protruding direction of the pair of mounting pieces 22.

[0036] With holder H attached to lighting duct D via attachment member A, a locking protrusion 26 that can be locked onto the inner surface of a polarity confirmation protrusion 71a of one side plate 71 of the lighting duct D is formed along the longitudinal direction of base plate 21 at the other end (outer end) along the width direction of base plate 21 of holder H, and a pair of locking plate portions 27 that can be locked onto the end surface of one locked flange plate portion 73 of the lighting duct D are formed upright at a right angle to base plate 21 at the inner end along the width direction of base plate 21, and at both longitudinal ends. Elastically deformable holding pieces 28 are formed integrally on the outside of base plate 21, standing in the same direction as the locking plate portions 27. The holding piece 28 is formed thinner than the base plate 21 and the pair of assembly pieces 22 to enable elastic deformation, and in order to secure a holding space between the outer surface of the side plate 71 of the lighting duct D, the holding space forming extension plate 28a is formed extending in the opposite direction from the pair of assembly pieces 22 with respect to the base plate 21, a spring plate 28b is formed at the outer end in the width direction of the holding space forming extension plate 28a and is curved in the rising direction of the locking plate 27, and a spring plate 28b is similarly curved at the upper end of the spring plate 28b. and a first holding space forming curved plate portion 28c which forms a holding space V for the cable C between itself and the outer surface of the side plate portion 71 of the lighting duct D; a second holding space forming curved plate portion 28d which is integrally formed at the upper end of the first holding space forming curved plate portion 28c and which forms a holding space V' for the small diameter cable C'; and a grip portion 28e which an operator can grip to greatly bend the first holding space forming curved plate portion 28c outward when placing the cables C, C' in each of the holding spaces V, V'.

[0037] The overall height of the holding piece 28 of the holder H is dimensioned such that, in a state where the holder H is disposed outside one side plate portion 71 of the writing duct D via the attachment body A, it is within the range along the height direction of the writing duct D, in other words, it does not protrude beyond the top plate portion 72 of the writing duct D. With this dimensional design, there is an advantage that the cable C can be held outside the side plate portion 71 even when the writing duct D is directly fixed to the ceiling surface. However, in the present invention, as in the first embodiment, a configuration in which the upper end of the holding piece 28 protrudes beyond the top plate portion 72 of the writing duct D is not excluded.

[0038] 7 to 10 show the state in which the attachment body A and the holder H are rotatably connected. In order to attach the holder H to the lighting duct D via the attachment body A, it is necessary to assemble the attachment body A and the holder H in advance. As shown in Figure 1, this assembly is performed by orienting the pair of retaining pieces 28 of retaining body H toward attachment body A, and aligning the longitudinal direction of retaining body H with the longitudinal direction of the inner locking plate portion 2 of attachment body A, and then bringing both A and D closer together.The assembly guide piece portions 22a at the tips of the pair of retaining pieces 28 abut against the outer peripheral surface of the connecting tube portion 5 of attachment body A, and the pair of retaining pieces 28 expand due to elastic deformation and then return to their original shape.As shown in Figure 9, the connecting tube portion 5 of attachment body A is relatively fitted into the fitting hole 23 formed in the base end half of the pair of retaining pieces 28, and the attachment A and retaining body H are assembled in a rotatably connected state. 10(b), in this assembled state, anti-rotation ridge 5a formed along the axial direction on the outer peripheral surface of connecting tube portion 5 of attachment body A fits into anti-rotation recess 22b formed on one of the pair of assembly pieces 22 of holder H, so that attachment body A and holder H are assembled with the longitudinal direction of inner locking plate 2 of attachment body A and the longitudinal direction of holding piece 28 of holder H aligned in the same direction, with relative rotation between attachment body A and holder H lightly restricted. This facilitates the attachment of attachment body A to lighting duct D by inserting inner locking plate 2 of attachment body A into insertion opening 74 of lighting duct D. In addition, the assembled state of the attachment body A and the holding body H in Figures 7 to 9 shows a state in which the longitudinal direction of the inner locking plate portion 2 of the attachment body A and the longitudinal direction of the holding piece 28 of the holding body H are perpendicular to each other, and the holding body H is attached to the lighting duct D via the attachment body A.

[0039] And in order to hold the cable C on the outer side of one side plate portion 71 of the writing duct D by using the cable holder B in which the attaching body A and the holding body H are rotatably assembled, it is carried out as follows. First, in the initial assembled state of the attaching body A and the holding body H, as shown in FIGS. 3(a) and 4(a), the longitudinal direction of the inner locking plate portion 2 of the attaching body A coincides with the longitudinal direction of the holding body H, and the longitudinal direction of the inner locking plate portion 2 of the attaching body A is arranged along the forming direction of the insertion opening 74 of the writing duct D. Until both outer ends in the width direction of the outer locking plate portion 3 directly below the inner locking plate portion 2 abut against the back surface of the pair of locked flange plate portions 73 of the writing duct D, when the inner locking plate portion 2 is inserted into the writing duct D, as shown in FIG. 6, the pair of locking plate portions 27 of the holding body H rotatably connected to the attaching body A are arranged to face the inner end surface of one of the locked flange plate portions 73 of the writing duct D, and the locking ridge 26 of the holding body H is arranged to face the inner surface of the polarity confirmation protrusion portion 71a protruding from the lower end portion of one side plate portion 71 of the writing duct D. In a state where the holding body H is prevented from coming out of the writing duct D, the holding piece 28 of the holding body H is arranged outside one side plate portion 71 of the writing duct D, and a holding space V for the cable C is formed between the holding piece 28 and the outer surface of the side plate portion 71.

[0040] In this state, when the attachment body A with the inner locking plate portion 2 inserted into the writing duct D is rotated 90° to the right as viewed from below about the axis J of the rotation shaft portion 4, as shown in FIG. 5(a), the rounded surface portion 4a of the rotation shaft portion 4 rotates ahead of the inner end surface of the locked flange plate portion 73, thereby avoiding interference with the locked flange plate portion 73. As shown in FIG. 5(b), each surface having the anti-rattle ridge 4b of the rotation shaft portion 4 becomes parallel to the inner end surface of each locked flange plate portion 73, and each anti-rattle ridge 4b bites into the inner end surface of each locked flange plate portion 73, thereby restricting the rotation of the attachment body A in the same direction with respect to the writing duct D (rotation beyond this becomes impossible), and the attachment body A is fixed to the writing duct D without rattling. As a result, as shown in FIGS. 3(b), 4(b), and 6, the attachment body A is firmly fixed to the writing duct D by the inner and outer locking plate portions 2 and 3 of the attachment body A sandwiching the pair of locked flange plate portions 73 of the writing duct D.

[0041] With respect to the writing duct D, the cable holder B is fixed at a plurality of locations at predetermined intervals according to the length of the cable C to be wired. As shown in FIG. 6, the cable C is held by gripping the gripping portion 28e of the holding piece 28 of the holding body H, separating the holding piece 28 from the side plate portion 71 of the writing duct D, passing the cable C through the cable insertion opening formed thereby into the holding space V, and then releasing the holding piece 28. The holding piece 28 restores to its original shape by elastic deformation, and the cable C is held in the holding space V. As a result, the cable C is arranged adjacent to the side plate portion 71 of the writing duct D without sagging. In addition to the good appearance of the arrangement state of the cable C, the risk that the cable C will be caught by articles passing near the writing duct D is eliminated.

[0042] Furthermore, directly below the lighting duct D, the attachment body A and the holder H are assembled together so that they cannot rotate, by engaging the anti-rotation protrusion 5a of the connecting tube portion 5 of the attachment body A with the anti-rotation recesses 22b formed on a pair of assembly pieces 22 of the holder H. With the cable C arranged along the longitudinal direction of the outer surface of one of the side plate portions 71 of the lighting duct D, and the holding piece 28 of the cable holder B positioned close to the side of the cable C, the cable holder B is then moved slightly in a direction approaching the side plate portion 1 of the lighting duct D, and the inner locking plate portion 2 of the attachment body A is inserted into the interior through the insertion opening 74 of the lighting duct D, and the entire attachment body A is rotated, and the cable C is positioned in the holding space V between the holding piece 28 and the side body portion 71 of the lighting duct D without elastically deforming the holding piece 28. [Example]

[0043] The cable holder B' of the second embodiment of the present invention comprises the attachment A attached to the general duct D' and a holder H' that can be retrofitted to the attachment A. In describing the cable holder B', the same parts as those in the cable holder B of the first embodiment are designated by the same reference numerals, and parts that have different shapes but perform the same functions are designated by the same reference numerals with an "'" to avoid redundant description of the same parts and to describe only the differences. The general duct D' has a pair of parallel, opposing side plates 71' whose upper ends are rotatably connected to a top plate 72', and the lower ends of each side plate 71' are bent inward at a right angle to form a pair of locking flange plates 73'. The opening between the locking flange plates 73' forms an insertion opening 74' for the inner locking plate 2 of the attachment A. The attachment A is attached to the general duct D' in the same manner as in the first embodiment.

[0044] The holder H' that can be retrofitted and assembled to the attachment body A already attached to the general duct D' is made capable of being retrofitted and assembled to the attachment body A already attached to the general duct D' by omitting a pair of locking plate portions 27 provided upright with respect to the substrate portion 21 of the holder H. That is, by pressing and inserting a pair of assembly pieces 22 of the holder H' into the gap between the outer locking plate portion 3 of the attachment body A already attached to the general duct D' and the base upper plate portion 7, after a pair of assembly guide piece portions 22a at the tip ends of the pair of assembly pieces 22 abut against the connecting cylinder portion 5 and are expanded by elastic deformation and then restored to the original shape, the pair of assembly pieces 22 are assembled in an externally fitted state with respect to the connecting cylinder portion 5.

[0045] Here, the sizes (outer diameters) of the cables wired to the side portions of the writing duct D and the general duct D' vary. In the case of a cable C' with a small diameter, the force to release the assembly with the already attached attachment body A and separate the holder H' from the general duct D' is relatively small compared to that for a large-diameter duct. Therefore, the pair of assembly pieces 22 of the holder H' can be assembled and maintained in an externally fitted state with respect to the connecting cylinder portion 5 of the attachment body A.

Example

[0046] The cable holders B and B' of Examples 1 and 2 are both in the shape of a hollow square cylinder, and insertion openings 35 and 35' for inserting the inner locking plate portion 2 of the attachment body A are formed only on one specific surface thereof, and the attachment body A is attached by a locking structure only on the surface having the insertion openings 35 and 435'. On the other hand, the wiring and pipe holder K of Example 3 has openings formed on all four surfaces, and the attachment body A is attached to a long frame F called an aluminum frame to which various articles can be attached on any surface, and the wiring and pipes are held at the side portion of the long frame F by a holding piece 28 of a holder H' rotatably connected to the attachment body A. This is different from the cable holders B and B' of Examples 1 and 2.

[0047] The long frame F made of an aluminum frame has an irregular square cylindrical shape as a whole. At each corner of the central cylindrical wall portion 31 with a square cross-section, a total of four side wall plate portions 32 are integrally provided outward along a pair of diagonal directions (in the radial direction with respect to the center of the central cylindrical wall portion 31). At the tip of each side wall plate portion 32, a groove forming body portion 33 with an L-shaped cross-section is provided. In each groove forming body portion 33, two thick flange plate portions 34 are arranged orthogonally so as to form each corner portion of the long frame F. As a result, the flange plate portions 34 extend from each adjacent corner portion toward the other side, and insertion openings 35 are respectively formed between the opposed flange plate portions 34 on each of the four surfaces of the long frame F. At the inner part of each insertion opening 35, a member arrangement space 36 is formed by the central cylindrical wall portion 31, a pair of adjacent side wall plate portions 32, and a pair of opposed flange plate portions 34.

[0048] In any part of the four insertion openings 35 of the irregular square tubular long frame F, the structure of the wiring and pipe material holder K that can be attached is substantially the same as the structure of the cable holder B, and the method of attaching the wiring and pipe material holder K to the long frame F is also the same. That is, the inner locking plate portion 2 of the attaching body A that constitutes the wiring and pipe material holder K is arranged along the longitudinal direction of the insertion opening 35, and the holding piece 28 of the holding body H rotatably connected to the attaching body A is arranged adjacent to another outer surface orthogonal to the outer surface where the insertion opening 35 is formed. In this state, when the entire attaching body A is rotated 90° around the axis J of the rotation shaft portion 4, the holding piece 28 maintains its original arrangement position before rotating the attaching body A, and is oppositely arranged by the inner and outer locking plate portions 2 and 3 of the attaching body A, and a pair of flange plate portions 34 that form the insertion opening 35 between their tips are clamped from the inside and outside, and the attaching body A is fixedly attached to the long frame F. Then, a cable C, which is one of the wiring and pipe materials, is inserted and arranged in the holding space V between another outer surface adjacent to and orthogonal to the outer surface of the long frame F where the attaching body A is fixedly attached and the holding piece 28. As a result, since the cable C is arranged adjacent to the outer surface of the long frame F, it is visually recognized as being integrated with the long frame F, improving the appearance.

[0049] The above aluminum frame is an example of a long frame. The long frame in claim 9 is not limited to the above aluminum frame as long as an insertion opening is formed between the tips of the oppositely arranged flange portions and a member arrangement space is formed at the inner part of the insertion opening. In other words, the long body in claim 9 is one in which an insertion opening is formed between the tips of the oppositely arranged flange plate portions, a groove for forming a member arrangement space is formed on one outer surface at the inner part of the insertion opening, and a similar groove is formed on another outer surface adjacent to and orthogonal to the one outer surface. The wiring and pipe material holder according to claim 9 is one in which a part of itself is inserted and fixed in the groove and can hold the wiring and pipe materials arranged along another outer surface adjacent to and orthogonal to the one outer surface.
