Description

[Technical field]

[0001] The present invention relates to a wiring / piping material support that is fixed to a hanging bolt to support wiring / piping material, and to a fixing portion structure provided on the wiring / piping material support. [Background technology]

[0002] Conventionally, various wiring and piping material supports have been used to support wiring and piping materials such as cables in structures such as houses. One of these various wiring and piping material supports is a type that installs wiring and piping materials in a structure by fixing the wiring and piping material support to a suspension bolt and supporting the wiring and piping material with the wiring and piping material support.

[0003] For example, Patent Document 1 relates to a wiring / piping material holder (wiring / piping material support) that is attached to a hanging bolt or the like and holds wiring / piping material. As shown in the reference diagram of the usage state of Patent Document 1, with the hanging bolt housed between the fixing parts of the wiring / piping material holder, the article is rotated around the hanging bolt as an axis to fit the hanging bolt into the fixing parts and fix the wiring / piping material holder to the hanging bolt. Alternatively, as shown in the reference diagram 2 of the usage state of Patent Document 1, the holding parts of the wiring / piping material holder are pulled left and right to widen the clamping parts, the hanging bolt is clamped in the clamping parts, and the claw parts are fitted into the valley parts of the outer periphery of the bolt to fix the wiring / piping material holder to the hanging bolt. Then, the piping material is laid within the holding portion of the wiring / piping material holder, and a first locking portion provided at the tip of the holding piece is engaged with a first engagement portion provided on the item holding portion, thereby sealing the opening between the holding piece and the holding portion, and the holding piece presses down on the piping material, thereby holding the piping material so that it does not fall off the holding portion.

[0004] [Patent Document 1] Design Registration No. 1304878 Summary of the Invention [Problem to be solved by the invention]

[0005] The wiring / piping material holder of Patent Document 1 can be attached to the hanging bolt by different attachment methods by selectively using the fixing part and the clamping part. However, since the fixing part is formed so as to protrude outward from the holding part in the width direction of the wiring / piping material holder (the direction in which the wiring / piping material is laid), when the wiring / piping material holder is attached to the hanging bolt using the fixing part, the axis of the hanging bolt and the holding part are separated in the width direction. Due to the positional relationship between the two (the separation distance in the width direction), the load received by the holding part is not effectively transmitted to the hanging bolt, and the load received by the fixing part increases, so that, for example, the fixing part may come off the hanging bolt or the fixing part of the wiring / piping material support may be damaged due to a load in the up-down or front-back twisting direction. Therefore, in the conventional wiring / piping material support, there was a risk that the support of the wiring / piping material may become unstable.

[0006] The present invention has been made to solve the above-mentioned problems, and its object is to provide a wiring / piping material support and fixing structure that enable stable support of wiring / piping material. [Means for solving the problem]

[0007] The wiring / piping material support according to claim 1 is a wiring / piping material support that includes a base and a support portion extending from the base, and that supports wiring / piping material by laying the wiring / piping material along a width direction perpendicular to a direction in which the support portion extends, The base portion includes a first fixing portion that is fixed to a first suspension bolt that extends in an axial direction and has a first diameter, and a second fixing portion that is fixed to a second suspension bolt that extends in the axial direction and has a second diameter, the first fixing portion includes a pair of first opposing walls that face each other and form a first arrangement space in which the first suspension bolt is arranged inside, a first opening that connects the first arrangement space to the outside and through which the first suspension bolt can pass in a radial direction, and a first rear wall that faces the first opening and connects the pair of first opposing walls at the rear of the first arrangement space, the second fixing portion includes a pair of second opposing walls that face each other and form a second arrangement space in which the second hanging bolt is arranged inside, a second opening that connects the second arrangement space to the outside and through which the second hanging bolt can pass in a radial direction, and a second rear wall that faces the second opening and connects the pair of second opposing walls at the rear of the second arrangement space, the first opening and the second opening being open so as to face in opposite directions from each other in the width direction, The first and second fixing portions are configured to hold the axial centers of the first and second hanging bolts at positions overlapping with the support portions in the width direction.

[0008] The wiring / piping material support according to claim 2 is the wiring / piping material support according to claim 1, wherein the first and second fixing portions further include first and second abutment portions that abut against the first and second hanging bolts from the open sides of the first and second openings at positions axially spaced from the first and second rear walls, respectively; The present invention is characterized in that an axial distance between the first contact portion and the first rear wall is different from an axial distance between the second contact portion and the second rear wall.

[0009] The wiring / piping material support according to claim 3 is the wiring / piping material support according to claim 2, wherein the first and second fixing portions further include first and second locking portions that lock onto outer surfaces of the first and second suspension bolts arranged in the first and second arrangement spaces, respectively, to prevent the first and second suspension bolts from coming off the first and second openings, In at least one of the first and second fixing portions, the axial distance between the locking portion and the support portion is greater than the axial distance between the abutment portion and the support portion.

[0010] The wiring / piping material support of claim 4 is characterized in that, in the wiring / piping material support of claim 1 or 2, the first and second abutment portions are formed below the first and second rear walls, respectively, and the axial distances between the first and second abutment portions and the first and second rear walls are larger than the diameters of the first and second hanging bolts, respectively.

[0011] The wiring / piping material support according to claim 5 is the wiring / piping material support according to any one of claims 1 to 3, wherein the second diameter is relatively larger than the first diameter, The second fixing portion further includes an obstructing portion arranged to obstruct the first hanging bolt from passing through the second opening.

[0012] The wiring / piping material support described in claim 6 is characterized in that, in the wiring / piping material support described in any one of claims 1 to 3, the first and second outer surfaces facing both sides in the width direction of the wiring / piping material support have different designs with projections and recesses.

[0013] The fixing structure described in claim 7 is a fixing structure for fixing the base to a suspension bolt having a predetermined diameter and including a base and a support extending from the base, the fixing structure being provided on a wiring / piping material support that lays and supports wiring / piping material along a width direction perpendicular to the extension direction of the support, and extending in an axial direction, A pair of opposing walls that face each other and define an arrangement space in which the hanging bolt is arranged inside; an opening that is open in a width direction so as to communicate the arrangement space with the outside and through which the hanging bolt can pass from a radial direction; a rear wall that faces the opening and connects the pair of opposing walls at the rear of the arrangement space; a contact portion that contacts the hanging bolt from the opening side at a position axially separated from the inner wall; a locking portion that locks onto an outer surface of the hanging bolt arranged in the arrangement space to prevent the hanging bolt from coming off from the opening, The locking portion is configured to determine a position of the hanging bolt in the arrangement space so that the axis of the hanging bolt is arranged at a position overlapping with the support portion in the width direction, The axial distance between the locking portion and the support portion is greater than the axial distance between the contact portion and the support portion. Effect of the Invention

[0014] According to the wiring / piping material support of claim 1, the base portion fixed to the hanging bolt is provided with two fixing portions consisting of a first fixing portion and a second fixing portion, and the first opening and the second opening are opened so as to face in opposite directions in the width direction perpendicular to the extension direction of the support portion. In this way, by providing the opening of the fixing portion perpendicular to the extension direction of the support portion, it is possible to form the first fixing portion and the second fixing portion on the inside of the support portion in the width direction without interfering with the support portion. And, the first and second fixing portions are configured to hold the axial centers of the first and second hanging bolts in positions overlapping with the support portions in the width direction, respectively. That is, even if either of the two fixing portions is fixed to the hanging bolt, the axial center of the fixed hanging bolt is located within the range of the support portion in the width direction. This allows the load that the support portion receives from the wiring / piping material to be effectively transmitted to the hanging bolt via the fixing portion. Therefore, the wiring / piping material support of the present invention enables stable support of the wiring / piping material.

[0015] According to the wiring / piping material support device of claim 2, in addition to the effect of the invention of claim 1, each fixing part is provided with an abutment part that abuts against the hanging bolt from the open side of each opening at a position axially separated from each back wall. When the hanging bolt is arranged in the arrangement space, the abutment part abuts against the hanging bolt from the opposite side of the back wall, thereby preventing the hanging bolt from slipping out from the open side of the opening. In addition, the axial distance between the first abutment part and the first back wall is different from the axial distance between the second abutment part and the second back wall, so that the user is given a different operating feeling when the first fixing part is used and when the second fixing part is used. In other words, by giving the user a different operating feeling, information is provided as to which fixing part is being used, and it is expected that the user will notice a mistake.

[0016] According to the wiring / piping material support of claim 3, in addition to the effect of the invention of claim 2, in at least one of the two fixing parts, the axial distance between the locking part and the support part is greater than the axial distance between the abutting part and the support part, so that the abutting part, which is closer to the support part than the locking part, can bear the tensile load in the longitudinal direction (laying direction) of the supported wiring / piping material preferentially. Then, the posture of the entire wiring / piping material support is less likely to change in the direction in which the hanging bolt comes out of the locking part, and as a result, the wiring / piping material support is effectively prevented from coming off the hanging bolt.

[0017] According to the wiring / piping material support of claim 4, in addition to the effects of the invention of claim 2 or 3, in each fixing portion, the abutment portion is formed below the rear wall, and the axial distance between the abutment portion and the rear wall is larger than the diameter of the hanging bolt, so that when fixing the wiring / piping material support to the hanging bolt, the hanging bolt can be inserted between the rear wall and the abutment portion, and then the base can be tilted with the abutment portion as a fulcrum, thereby pushing the hanging bolt into the arrangement space between the pair of opposing walls through the opening. In other words, the wiring / piping material support can be easily fixed to the hanging fixture.

[0018] According to the wiring / piping material support device of claim 5, in addition to the effect of any one of claims 1 to 3, the second fixing part is provided with an obstructing part that obstructs the first hanging bolt from passing through the second opening. That is, the first hanging bolt, which has a smaller diameter, is obstructed from passing through the second opening via the obstructing part. This makes it possible to provide the user with notice of an erroneous operation when attempting to insert the first hanging bolt into the second fixing part, thereby improving operational efficiency.

[0019] According to the wiring / piping material support described in claim 6, in addition to the effects of any one of claims 1 to 3, the first and second outer surfaces facing both sides in the width direction of the wiring / piping material support are provided with different designs, making it easy for the user to distinguish by appearance and touch whether they are using the first fixing part or the second fixing part.

[0020] According to the fixing part structure of claim 7, the base part fixed to the hanging bolt is provided with a fixing part, and the opening is opened so as to face the width direction perpendicular to the extension direction of the support part. In this way, by providing the opening of the fixing part perpendicular to the extension direction of the support part, it is possible to form the fixing part inside the support part in the width direction without interfering with it. Then, the locking part is configured to determine the position of the hanging bolt in the arrangement space so that the axis of the hanging bolt is positioned at a position overlapping with the support part in the width direction. In other words, when the fixing part is fixed to the hanging bolt, the axis of the fixed hanging bolt is located within the range of the support part in the width direction. This makes it possible to effectively transmit the load that the support part receives from the wiring / piping material to the hanging bolt via the fixing part. Furthermore, since the axial distance between the locking part and the support part is larger than the axial distance between the abutting part and the support part, the abutting part closer to the support part than the locking part can preferentially receive the load for the tensile load in the longitudinal direction (laying direction) of the supported wiring / piping material. The fixing part structure of the present invention therefore enables the wiring / piping material support to stably support the wiring / piping material. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the shapes of the figures referred to in the following description are conceptual or schematic diagrams for explaining preferred shapes and dimensions, and the dimensional ratios do not necessarily match the actual dimensional ratios. In other words, the present invention is not limited to the dimensional ratios in the drawings. Furthermore, the up, down, left, and right directions in the present invention are merely concepts indicating relative positions, and it goes without saying that they can be applied by being interchanged.

[0023] The wiring / piping material support 100 according to one embodiment of this invention is configured to be fixed to a hanging bolt and to hold the wiring / piping material (specifically, a cable) that is the object to be supported at a predetermined height. Here, the wiring / piping material support 100 is configured to be attachable to both a first hanging bolt 11 (see Figs. 13 to 16) having a first diameter and a second hanging bolt 13 (see Figs. 17 to 20) having a second diameter that is relatively larger than the first diameter. Hereinafter, the configuration of the wiring / piping material support 100 according to this embodiment will be described with reference to Figs. 1 to 12.

[0024] 1(a) and (b) are a front perspective view and a rear perspective view of a wiring / piping material support 100 according to one embodiment of the present invention. FIG. 2 is a plan view of the wiring / piping material support 100. FIG. 3 is a front view of the wiring / piping material support 100. FIG. 4 is a rear view of the wiring / piping material support 100. FIG. 5 is a bottom view of the wiring / piping material support 100. FIGS. 6(a) and (b) are left side view and right side view of the wiring / piping material support 100. FIGS. 7 to 12 are cross-sectional views of various portions of the wiring / piping material support 100.

[0025] The wiring / piping material support 100 includes a base 101 and a pair of support parts 103 extending in both directions from the base 101. The base 101 extends in the axial direction at approximately the center of the wiring / piping material support 100 in a plan view. The base 101 also includes a pair of side walls extending to sandwich a hanging bolt arranged along the axial direction. Openings are provided at the front and rear of the base 101, and the top and bottom of the axial direction of the base 101 are open. The pair of support parts 103 extend a predetermined length from the outer surface of the side wall of the base 101 in the extension direction (left and right direction in a plan view) perpendicular to the axial direction. In this embodiment, the pair of support parts 103 have the same shape, but may have different shapes. The wiring / piping material support 100 is configured to lay and support the wiring / piping material along the width direction perpendicular to the extension direction of each support part 103 with the base 101 attached to the hanging bolt. Here, the extension direction and the width direction are defined as directions perpendicular to each other in a plane perpendicular to the axial direction.

[0026] The wiring / piping material support 100 has different configurations and designs on its front and rear outer surfaces, as shown in Fig. 3 and Fig. 4. That is, the outer surface of the wiring / piping material support 100 shown in the front view of Fig. 3 is the first outer surface, and the outer surface shown in the back view of Fig. 4 is the second outer surface. As described below, the first outer surface is provided with a first fixing portion 110 that can be attached to a first hanging bolt having a first diameter, and the second outer surface is provided with a second fixing portion 120 that can be attached to a second hanging bolt having a second diameter relatively larger than the first diameter. These are used differently depending on the diameter of the hanging bolt.

[0027] In addition, the first and second outer surfaces of the wiring / piping material support 100 have different designs based on projections and recesses. Specifically, a groove 101a is formed on the end surface of the front surface (first outer surface) of the side wall of the base 101, while the end surface of the rear surface (second outer surface) is flat without any groove (recess). In addition, a plurality of front ribs 105b extending in the radial direction are formed on the front surface (first outer surface) of the support portion 103 (standing portion 105), while the rear surface (second outer surface) is flat without any ribs (projections). In other words, the first and second outer surfaces facing both sides in the width direction of the wiring / piping material support 100 have different designs based on projections and recesses. This makes it easy for the user to distinguish by appearance or touch whether the first outer surface (first fixing portion 110) or the second outer surface (second fixing portion 120) is being used.

[0028] As shown in Figures 3 and 7, the support part 103 extends from the axial lower part of the base part 101 and forms an arm part curved like an arc. The inner surface of this support part 103 is configured to place wiring / piping material on it. In particular, the support part 103 extends from the side surface of the base part 101 and includes a support surface 104 facing upward, an erected part 105 erected at the tip side of the support surface 104, and an introduction part 106 formed between the tip of the erected part 105 and the side surface of the base part 101 for introducing the wiring / piping material.

[0029] The support surface 104 has a predetermined width in the width direction and is a curved surface that curves in the extension direction. The most recessed central position (lowest axial position) of the support surface 104 mainly supports the wiring / piping material and is therefore most susceptible to load from the wiring / piping material. Therefore, the central position of the support surface 104 is set as the reference position in the axial direction of the support part 103.

[0030] The standing portion 105 stands axially upward from the tip of the support surface 104 and is configured to restrict the lateral movement of the wiring / piping material from the support surface 104. The standing portion 105 has an inner surface that is continuous in an arc with the inner surface of the support surface 104. In addition, an outer peripheral rib 105a extending in an arc for reinforcing the support portion 103 is formed on the outer surface of the standing portion 105.

[0031] The introduction section 106 is configured to open the support section 103 upward in the axial direction and introduce the wiring / piping material onto the support surface 104 of the support section 103. The introduction section 106 is provided with an inner elastic piece 106a formed on the base section 101 side and an outer elastic piece 106b formed on the standing section 105 side. The inner elastic piece 106a and the outer elastic piece 106b close the introduction section 106 in the original shape, but can open the introduction section 106 by elastically tilting downward with their base ends as fulcrums. That is, when the wiring / piping material passes through the introduction section 106 from above, the inner elastic piece 106a and the outer elastic piece 106b are elastically deformed to open the introduction section 106. In addition, the upper surfaces of the inner elastic piece 106a and the outer elastic piece 106b are inclined so that their tips face downward in the axial direction. As a result, the inner elastic piece 106a and the outer elastic piece 106b can guide the wiring / piping material into place on the support surface 104, while effectively preventing the wiring / piping material from unintentionally slipping out from inside the support portion 103.

[0032] A first fixing portion 110 is provided on a first outer surface of the base 101 and can be attached to a first hanging bolt having a first diameter, and a second fixing portion 120 is provided on a second outer surface of the base 101 and can be attached to a second hanging bolt having a second diameter relatively larger than the first diameter. For example, the first hanging bolt 11 is a 3-part hanging bolt and has a diameter of 9.53 mm. The second hanging bolt 13 is a 4-part hanging bolt and has a diameter of 11.35 mm.

[0033] The first fixing part 110 is mainly shown in Figures 1(a), 2, 3, 5, 6(b), 8, 10 and 12. Here, the BB cross section shown in Figure 8 is a cross section cut by a plane along the extension direction and axial direction so as to pass through the center of the first arrangement space 113 of the first fixing part 110. Also, the DD cross section shown in Figure 10 is a cross section cut by a plane along the width direction and extension direction so as to pass through the first locking part 116 of the first fixing part 110. The first fixing portion 110 comprises a pair of first opposing walls 111 which face each other and form a first arrangement space 113 in which the first hanging bolt 11 is arranged inside; a first opening 112 which connects the first arrangement space 113 to the outside and through which the first hanging bolt 11 can pass from the radial direction; a first rear wall 114 which faces the first opening 112 and connects the pair of first opposing walls 111 at the rear of the first arrangement space 113; a first abutment portion 115 which abuts against the first hanging bolt 11 from the open side of the first opening 112 at a position axially spaced from the first rear wall 114; and a first engagement portion 116 which engages with the outer surface of the first hanging bolt 11 arranged in the first arrangement space 113 to prevent it from coming off from the first opening 112.

[0034] The pair of first opposing walls 111 are formed as part of the side wall on the first outer surface side of the base 101, are spaced apart in the extension direction by a distance that allows the first hanging bolt 11 to be sandwiched therebetween, and extend in the axial direction and width direction. The distance between the pair of first opposing walls 111 is preferably approximately the same as the diameter of the first hanging bolt 11. In addition, a first opening 112 is formed at the tip of the pair of first opposing walls 111, and the first hanging bolt 11 can be introduced into the first arrangement space 113 between the pair of first opposing walls 111 through the first opening 112. The opening width of the first opening 112 is smaller than the second diameter and approximately the same as the first diameter. In other words, the first opening 112 cannot receive the second hanging bolt 13. A first back wall 114 is formed so as to connect the base ends of the pair of first opposing walls 111. A screw groove is formed on the surface of the first rear wall 114 facing the first opening 112 so as to correspond to the screw thread shape on the outer periphery of the first hanging bolt 11. Moreover, as shown in Fig. 12, the surface of the first rear wall 114 facing the first opening 112 has an arc shape in cross section so as to follow the outer periphery shape of the first hanging bolt 11. That is, a first arrangement space 113 capable of holding the first hanging bolt 11 is defined inside the pair of first opposing walls 111, the first opening 112, and the first rear wall 114.

[0035] As shown in FIG. 10, a first locking portion 116 is formed to protrude from the opposing surfaces of the pair of first opposing walls 111. The first locking portion 116 protrudes so as to slightly narrow the opening width of the first opening 112, and is configured to provide resistance to the passage of the first hanging bolt 11. In other words, the first locking portion 116 allows the first hanging bolt 11 to move over the first locking portion 116 only when a strong force is applied to the first hanging bolt 11 toward the inside and outside of the first arrangement space 113, and can be locked to the outer surface of the first hanging bolt 11 in other cases. In other words, the first locking portion 116 can be locked to the outer surface of the first hanging bolt 11 arranged in the first arrangement space 113 to suppress the first hanging bolt 11 from coming off the first opening 112. Here, when the first hanging bolt 11 moves, the recessed groove 101a acts to allow the locking portion 116 to escape outward.

[0036] The first locking portion 116 functions to determine the position of the first suspension bolt 11 in the first arrangement space 113. In particular, the first suspension bolt 11 is positioned by the first locking portion 116 so that the outer surface of the first suspension bolt 11 abuts against the first rear wall 114. That is, the position of the axis of the first suspension bolt 11 arranged in the first arrangement space 113 is determined by the first opposing wall 111, the first rear wall 114, and the first locking portion 116. A center position 113a of the first arrangement space 113 is determined so as to coincide with the axis of the first suspension bolt 11. This center position 113a (i.e., the axis of the arranged first suspension bolt 11) is arranged at a position overlapping the support portion 103 (support surface 104) in the width direction, as shown in Figs. 2, 10, and 12 (and Fig. 14). In other words, the center position 113a where the axis of the fixed first hanging bolt 11 is located is disposed within the widthwise range of the support portion 103 and is not substantially separated from the support portion 103 in the widthwise direction.

[0037] As shown in Fig. 3, the first abutment portion 115 is formed at a position spaced axially downward from the first rear wall 114. The first abutment portion 115 is formed at the lower end of the first leg portion 107 that extends downward from the base portion 101 and the support portion 103 on the first outer surface side. As shown in Fig. 12, the first abutment portion 115 protrudes outward in the width direction from the first outer surface of the first leg portion 107 and is bent in an L shape so as to extend toward the opening side of the base portion 101. The first abutment portion 115 extends from the open side of the first opening 112 so as to be able to abut against the first suspension bolt 11 arranged in the first arrangement space 113. The first abutment portion 115 cooperates with the first rear wall 114 to clamp the first hanging bolt 11 from the front and rear, thereby stably maintaining the posture of the wiring / piping material support 100 relative to the first hanging bolt 11 and functioning to prevent the first fixing portion 110 from coming off the first hanging bolt 11 in the front-to-rear direction (opening side).

[0038] Further, a gap (without a fleshy portion) is formed between the first abutting portion 115 and the first inner wall 114, and the axial distance therebetween is larger than the first diameter of the first hanging bolt 11. This gap forms a first insertion portion 117 for inserting the first hanging bolt 11 when the first fixing portion 110 is fixed to the first hanging bolt 11 (see FIG. 16). Then, as shown in FIG. 3 and FIG. 6(b), a first guide surface 118 for guiding the first hanging bolt 11 to the first insertion portion 117 is formed adjacent to the extending direction of the first insertion portion 117. The first guide surface 118 forms an inclined surface provided on the second leg portion 108. The first guide surface 118 functions to guide the posture of the first hanging bolt 11 when it is inserted into the first insertion portion 117.

[0039] The second fixing portion 120 is mainly shown in Figures 1(b), 2, 4, 5, 6(a), 9, 11, and 12. Here, the CC section shown in Figure 9 is a section cut by a plane along the extension direction and the axial direction so as to pass through the center of the second arrangement space 123 of the second fixing portion 120. The EE section shown in Figure 11 is a section cut by a plane along the width direction and the extension direction so as to pass through the second locking portion 126 of the second fixing portion 120. The second fixing portion 120 comprises a pair of second opposing walls 121 which face each other and form a second arrangement space 123 in which the second hanging bolt 13 is arranged inside; a second opening 122 which connects the second arrangement space 123 to the outside and through which the second hanging bolt 13 can pass from the radial direction; a second rear wall 124 which faces the second opening 122 and connects the pair of second opposing walls 121 at the rear of the second arrangement space 123; a second abutment portion 125 which abuts against the second hanging bolt 13 from the open side of the second opening 122 at a position axially spaced from the second rear wall 124; a second engagement portion 126 which engages with the outer surface of the second hanging bolt 13 arranged in the second arrangement space 123 to prevent it from coming off from the second opening 122; and an inhibition portion 129 which is arranged to inhibit the first hanging bolt 11 from passing through the second opening 122.

[0040] The pair of second opposing walls 121 are formed as part of the side wall on the second outer surface side of the base 101, are spaced apart in the extension direction by a distance that allows the second hanging bolt 13 to be sandwiched therebetween, and extend in the axial and width directions. The distance between the pair of second opposing walls 121 is preferably approximately the same as the diameter of the second hanging bolt 13. In addition, a second opening 122 is formed at the tip of the pair of second opposing walls 121, and the second hanging bolt 13 can be introduced into the second arrangement space 123 between the pair of second opposing walls 121 through the second opening 122. The opening width of the second opening 122 is larger than the first diameter and approximately the same as the second diameter. In other words, the second opening 122 can receive both the first hanging bolt 11 and the second hanging bolt 13. A second back wall 124 is formed so as to connect the base ends of the pair of second opposing walls 121. Here, the second back wall 124 is formed integrally with the first back wall 114. A screw groove is formed on the surface of the second rear wall 124 facing the second opening 122 so as to correspond to the screw thread shape of the outer periphery of the second hanging bolt 13. Moreover, as shown in Fig. 12, the surface of the second rear wall 124 facing the second opening 122 has an arc shape in cross section so as to follow the outer periphery shape of the second hanging bolt 13. That is, a second arrangement space 123 capable of holding the second hanging bolt 13 is defined inside the pair of second opposing walls 121, the second opening 122 and the second rear wall 124.

[0041] As shown in FIG. 11, a second locking portion 126 is formed to protrude from the opposing surfaces of the pair of second opposing walls 121. The second locking portion 126 protrudes so as to slightly narrow the opening width of the second opening 122, and is configured to provide resistance to the passage of the second hanging bolt 13. In other words, the second locking portion 126 allows the second hanging bolt 13 to move over the second locking portion 126 only when a strong force is applied to the second hanging bolt 13 toward the inside and outside of the second arrangement space 123, and can be locked to the outer surface of the second hanging bolt 13 in other cases. In other words, the second locking portion 126 can be locked to the outer surface of the second hanging bolt 13 arranged in the second arrangement space 123 to suppress separation from the second opening 122. The second locking portion 126 is formed at a position shifted in the axial direction from the first locking portion 116.

[0042] The second locking portion 126 functions to determine the position of the second hanging bolt 13 in the second arrangement space 123. In particular, the second hanging bolt 13 is positioned by the second locking portion 126 so that the outer surface of the second hanging bolt 13 abuts against the second rear wall 124. That is, the position of the axis of the second hanging bolt 13 arranged in the second arrangement space 123 is determined by the second opposing wall 121, the second rear wall 124, and the second locking portion 126. A center position 123a of the second arrangement space 123 is determined so as to coincide with the axis of the second hanging bolt 13. This center position 123a (i.e., the axis of the arranged second hanging bolt 13) is arranged at a position overlapping the support portion 103 (support surface 104) in the width direction, as shown in Figs. 2, 11, and 12 (and Fig. 18). In other words, the center position 123a where the axis of the fixed second suspension bolt 13 is located is disposed within the width direction range of the support part 103 and is not substantially separated from the support part 103 in the width direction. In the second fixed part 120, the center position 123a and the edge of the support surface 104 on the second outer surface side are disposed on approximately the same plane.

[0043] As shown in FIG. 4, the second abutment portion 125 is formed at a position spaced axially downward from the second back wall 124. The second abutment portion 125 is formed at the lower end of the second leg portion 108 extending downward from the base portion 101 and the support portion 103 on the second outer surface side. The second abutment portion 125 is located axially above the first abutment portion 115 and is disposed at a position closer to the support surface 104. As shown in FIG. 12, the second abutment portion 125 protrudes outward in the width direction from the second outer surface of the second leg portion 108 and is bent in an L-shape so as to extend toward the opening side of the base portion 101. The second abutment portion 125 extends from the open side of the second opening 122 so as to be able to abut against the second suspension bolt 13 disposed in the second arrangement space 123. The second abutment portion 125 cooperates with the second rear wall 124 to clamp the second hanging bolt 13 from the front and rear, thereby stably maintaining the posture of the wiring / piping material support 100 relative to the second hanging bolt 13 and functioning to prevent the second fixing portion 120 from coming off the second hanging bolt 13 in the front-to-rear direction (opening side).

[0044] Further, a gap (without a fleshy portion) is formed between the second abutting portion 125 and the second back wall 124, and the axial distance therebetween is larger than the second diameter of the second hanging bolt 13. This gap forms a second insertion portion 127 through which the second hanging bolt 13 is inserted when the second fixing portion 120 is fixed to the second hanging bolt 13 (see FIG. 20). As shown in FIG. 4 and FIG. 6(a), a second guide surface 128 for guiding the second hanging bolt 13 to the second insertion portion 127 is formed adjacent to the extending direction of the second insertion portion 127. The second guide surface 128 forms an inclined surface provided on the first leg portion 107. The first guide surface 118 functions to guide the posture of the second hanging bolt 13 when it is inserted into the second insertion portion 127.

[0045] The inhibiting portion 129 extends from one side wall of the upper end of the base 101 and is a lid that covers an open portion above the base 101. The inhibiting portion 129 may be disposed so as to cross the second opening 122. The inhibiting portion 129 crosses an axially extended portion of the second opening 122 to interfere with the suspension bolt and inhibit the suspension bolt from passing through the second opening 122. The inhibiting portion 129 opens the second opening 122 (or the axially extended portion) by being bent upward or cut off, and allows the suspension bolt to pass through the second opening 122. In other words, the inhibiting portion 129 does not completely restrict the passage of the suspension bolt, but rather intentionally interferes or obstructs it to provide the user with operational awareness. For example, when a user fixes the wiring / piping material support 100 to the first hanging bolt 11, without the obstruction portion 129, the first hanging bolt 11 can pass through both the first opening 112 and the second opening 122, and the user cannot instantly determine which of the first fixing portion 110 and the second fixing portion 120 to use. In contrast, the obstruction portion 129 obstructs the first hanging bolt 11 from passing through the second opening 122, and thus assists the user in instantly determining whether to fix the first hanging bolt 11 to the first fixing portion 110. That is, the obstruction portion 129 is provided to the user to notice an erroneous operation when the first hanging bolt 11 is inserted into the second fixing portion 120, and the operation efficiency can be improved. On the other hand, when the second fixing portion 120 is fixed to the second hanging bolt 13, the second hanging bolt 13 is restricted from passing through the first opening 112, so that the user does not become confused.

[0046] Next, a description will be given of the main difference in the configuration between the first fixed portion 110 and the second fixed portion 120. The first abutting portion 115 is located axially lower than the second abutting portion 125, and the first locking portion 116 is located axially lower than the second locking portion 126, resulting in a difference in the positional relationship between the abutting portions and the locking portions between the first fixed portion 110 and the second fixed portion 120.

[0047] As shown in FIG. 3, the distance between the first rear wall 114 (lower edge) and the first abutment portion 115 (upper edge) is set as d1. On the other hand, as shown in FIG. 4, the distance between the second rear wall 124 (lower edge) and the second abutment portion 125 (upper edge) is set as d2. Comparing the two, d1 is larger than d2. These distances d1 and d2 affect the range of motion of the first suspension bolt 11 and the second suspension bolt 13 arranged in the first insertion portion 117 and the second insertion portion 127, respectively. This difference in the range of motion gives the user a different operating feel when the first fixing portion 110 is used and when the second fixing portion 120 is used. That is, by giving the user a different operating feel, information about which fixing portion is being used is provided, and it is expected that the user will notice the mistake. In the wiring / piping material support 100 of this embodiment, the first suspension bolt 11 is set as the suspension bolt that is used frequently. For this reason, the distance d1 at the first fixed portion 110 is designed to be larger than the distance d2 at the second fixed portion 120. This is because, in general, the larger the range of motion of the suspension bolt, the easier it is to attach the fixed portion to the suspension bolt.

[0048] As shown in FIG. 3, the axial distance between the first contact portion 115 (upper edge) and the support portion 103 (axial reference position of the support surface 104) is defined as x1, and the axial distance between the first locking portion 116 (lower edge) and the support portion 103 (axial reference position of the support surface 104) is defined as y1. The axial distance x1 between the first contact portion 115 and the support portion 103 is greater than the axial distance y1 between the first locking portion 116 and the support portion 103. On the other hand, as shown in FIG. 4, the axial distance between the second contact portion 125 (upper edge) and the support portion 103 (axial reference position of the support surface 104) is defined as x2, and the axial distance between the second locking portion 126 (lower edge) and the support portion 103 (axial reference position of the support surface 104) is defined as y2. In contrast to the first fixing part 110, the axial distance y2 between the second locking part 126 and the support part 103 is larger than the axial distance x2 between the second abutting part 125 and the support part 103. That is, in the second fixing part 120, the second abutting part 125, which is closer to the support part 103 than the second locking part 126, can receive the load related to the support part 103 preferentially. Furthermore, the axial distance x2+y2 between the second abutting part 125 and the second locking part 126 is relatively larger than the axial distance x1+y1 between the first abutting part 115 and the first locking part 116. Due to the principle of leverage, the greater the distance between the abutting part and the locking part, the smaller the force required to push the hanging bolt into the pair of opposing walls through the opening. In this embodiment, the second hanging bolt 13, which has a larger diameter, requires more force to be pushed in, but by ensuring a larger axial distance between the second abutment portion 125 and the second locking portion 126, the force required to push in is relatively reduced.

[0049] 13 to 15, a first support structure 10A in which wiring / piping material 15 is installed on a first suspension bolt 11 using the wiring / piping material support 100 of this embodiment will be described. Here, the first suspension bolt 11 is a 3-point suspension bolt, and its diameter is 9.53 mm.

[0050] In the first support structure 10A, the wiring / piping material support 100 is fixed to a first hanging bolt 11 extending in the vertical direction, and the wiring / piping material 15 is laid along the width direction of the support part 103 relative to the first hanging bolt 11. In Fig. 13, the first outer surface of the wiring / piping material support 100 faces the front, and the first hanging bolt 11 is arranged in a first arrangement space 113 between a pair of first opposing walls 111 via a first opening 112 of a first fixing part 110. As shown in Fig. 14, a first locking part 116 forming a protrusion is in pressure contact with the first hanging bolt 11 from the opening side, and determines the position of the first hanging bolt 11 in the first arrangement space 113. 15, the outer surface of the first hanging bolt 11 abuts against both the first rear wall 114 and the first abutment portion 115 with no gap, and the axis of the first hanging bolt 11 is held at the center position 113a of the first arrangement space 113. Furthermore, the thread shape of the first hanging bolt 11 and the thread groove shape of the first rear wall 114 mesh with each other, thereby restricting axial movement of the wiring / piping material support 100. In other words, the first fixing portion 110 is fixed to the first hanging bolt 11 without any rattling.

[0051] The wiring and piping material 15 is supported by the wiring and piping material support 100 fixed to the first hanging bolt 11. As shown in FIG. 13, the wiring and piping material 15 of two paths is placed on the support surface 104 of a pair of support parts 103. At this time, since the support surface 104 has a concave curved surface, the wiring and piping material 15 is placed at the center of the support surface 104. Therefore, the approximately central part of the support surface 104 of the support part 103 is the part that mainly receives the pulling direction and the vertical downward load from the wiring and piping material 15. FIG. 14 shows a straight line extending in the extension direction passing through the axis of the first hanging bolt 11 with a virtual line. As shown in FIG. 14, the virtual line is located on the support part 103, that is, the axis of the first hanging bolt 11 is located so as to overlap with the support part 103 in the width direction. That is, the axis of the first hanging bolt 11 is within the width range of the support part 103. As a result, when the support surface 104 receives a load from the wiring / piping material 15, the load can be effectively transmitted to the axis of the first hanging bolt 11 via the first fixing portion 110. Therefore, in the first support structure 10A, the wiring / piping material support 100 stably supports the wiring / piping material 15.

[0052] Next, with reference to FIG. 16, a method for attaching the wiring / piping material support 100 to the vertically erected first suspension bolt 11 in order to construct the first support structure 10A will be described.

[0053] As shown in FIG. 16(a), the wiring / piping material support 100 is held in a position facing sideways with respect to the first hanging bolt 11 when viewed from the front, and the first outer surface is made to face the first hanging bolt 11. Then, the wiring / piping material support 100 is operated so that the first hanging bolt 11 is inserted into the first insertion portion 117 between the first rear wall 114 and the first abutting portion 115. At this time, the position of the wiring / piping material support 100 can be guided to an inclination (for example, 19°) that allows the first hanging bolt 11 to be inserted into the first insertion portion 117 by making the first guide surface 118 face the outer surface of the first hanging bolt 11. Note that the inhibition portion 129 covers the space above the pair of second opposing walls 121, so that it is possible to prevent the user from erroneously attempting to fix the first hanging bolt 11 to the second fixing portion 120. Furthermore, compared to the case where the second fixing part 120 described below is used, the first fixing part 110 can reduce the tilt angle of the required initial tilt posture of the wiring / piping material support 100 relative to the first hanging bolt 11 due to the relationship d1>d2. For example, when attaching the wiring / piping material support 100 in a narrow space, the wiring / piping material support 100 can be operated without being tilted significantly.

[0054] Next, while the first suspension bolt 11 is abutted against the first abutment portion 115, the wiring / piping material support 100 is tilted with this abutment point as a fulcrum. As shown in FIG. 16(b), the wiring / piping material support 100 can be tilted without applying a strong force until the first suspension bolt 11 abuts against the first locking portion 116 from the first opening 112 side. Next, the wiring / piping material support 100 is pressed with a relatively strong force with the first locking portion 116 as a fulcrum so as to push the first suspension bolt 11 into the first arrangement space 113 between the pair of first opposing walls 111. Then, the user can move the first suspension bolt 11 into the first arrangement space 113 while feeling the resistance when the first suspension bolt 11 gets over the first locking portion 116. In this way, the wiring / piping material support 100 is fixed to the first suspension bolt 11 via the first fixing portion 110.

[0055] Finally, the wiring / piping material 15 is dropped onto the support surface 104 via the introduction portion 106 of the support portion 103 of the wiring / piping material support 100 fixed to the first hanging bolt 11, thereby constructing the first support structure 10A.

[0056] 17 to 19, a second support structure 10B in which wiring / piping material 15 is installed on a second suspension bolt 13 using the wiring / piping material support 100 of this embodiment will be described. Here, the second suspension bolt 13 is a quarter suspension bolt and has a diameter of 11.35 mm.

[0057] In the second support structure 10B, the wiring / piping material support 100 is fixed to the second hanging bolt 13 extending in the vertical direction, and the wiring / piping material 15 is laid along the width direction of the support part 103 with respect to the second hanging bolt 13. In FIG. 17, the second outer surface of the wiring / piping material support 100 faces the front, and the second hanging bolt 13 is arranged in the second arrangement space 123 between the pair of second opposing walls 121 through the second opening 122 of the second fixing part 120. Here, the obstruction part 129 is bent upward, so that the second hanging bolt 13 can be arranged in the second arrangement space 123. The obstruction part 129 may be broken off. As shown in FIG. 18, the second locking part 126 forming a protrusion is pressed against the second hanging bolt 13 from the opening side, and determines the position of the second hanging bolt 13 in the second arrangement space 123. 19, the outer surface of the second hanging bolt 13 abuts against both the second rear wall 124 and the second abutment portion 125 with no gap, and the axis of the second hanging bolt 13 is held at the center position 123a of the second arrangement space 123. Furthermore, the thread shape of the second hanging bolt 13 and the thread groove shape of the second rear wall 124 mesh with each other, thereby restricting axial movement of the wiring / piping material support 100. In other words, the second fixing portion 120 is fixed to the second hanging bolt 13 without any rattling.

[0058] The wiring and piping material 15 is supported by the wiring and piping material support 100 fixed to the second hanging bolt 13. As shown in FIG. 17, the wiring and piping material 15 of two paths is placed on the support surface 104 of a pair of support parts 103. At this time, since the support surface 104 has a concave curved surface, the wiring and piping material 15 is placed at the center of the support surface 104. Therefore, the approximately central part of the support surface 104 of the support part 103 is the part that mainly receives the load in the pulling direction and the vertical downward direction from the wiring and piping material 15. FIG. 18 shows a straight line extending in the extension direction passing through the axis of the second hanging bolt 13 with a virtual line. As shown in FIG. 18, the virtual line is located on the support part 103, that is, the axis of the second hanging bolt 13 is located so as to overlap with the support part 103 in the width direction. In other words, the axis of the second hanging bolt 13 is located on the edge of the width of the support part 103 (within the range of the width). As a result, when the support surface 104 receives a load from the wiring / piping material 15, the load can be effectively transmitted to the axis of the second hanging bolt 13 via the second fixing portion 120. Therefore, in the second support structure 10B as well, the wiring / piping material support 100 stably supports the wiring / piping material 15, similarly to the first support structure 10A.

[0059] Next, with reference to FIG. 20, a method of attaching the wiring / piping material support 100 to the vertically erected second suspension bolt 13 in order to construct the second support structure 10B will be described.

[0060] First, the inhibition portion 129 is bent upward or broken off to make the second fixing portion 120 usable. Next, as shown in FIG. 20(a), the wiring / piping material support 100 is held in a position facing the second hanging bolt 13 sideways when viewed from the front, and the second outer surface faces the second hanging bolt 13. Then, the wiring / piping material support 100 is operated so that the second hanging bolt 13 is inserted into the second insertion portion 127 between the second back wall 124 and the second abutment portion 125. At this time, the second guide surface 128 is placed against the outer surface of the second hanging bolt 13, so that the position of the wiring / piping material support 100 can be guided to an inclination (for example, 27.5°) that allows the second hanging bolt 13 to be inserted into the second insertion portion 127. Furthermore, since the second suspension bolt 13 cannot pass through the first opening 112, it is possible to prevent the user from mistakenly attempting to fasten the second suspension bolt 13 to the first fixing portion 110.

[0061] Next, while the second suspension bolt 13 is abutted against the second abutment portion 125, the wiring / piping material support 100 is tilted with this abutment point as a fulcrum. As shown in FIG. 20(b), the wiring / piping material support 100 can be tilted without applying a strong force until the second suspension bolt 13 abuts against the second locking portion 126 from the second opening 122 side. At this time, since the axial distance (d2) of the second insertion portion 127 is smaller than the axial distance (d1) of the first insertion portion 117, the range of motion of the second suspension bolt 13 is relatively small, giving the user a different operational feeling from that of the first fixing portion 110. Next, the wiring / piping material support 100 is pressed with a relatively strong force with the second locking portion 126 as a fulcrum so as to push the second suspension bolt 13 into the second arrangement space 123 between the pair of second opposing walls 121. Then, the user can move the second suspension bolt 13 into the second arrangement space 123 while feeling the resistance when the second suspension bolt 13 overcomes the second locking portion 126. At this time, since the axial distance (x2+y2) between the fulcrum (second abutment portion 125) and the point of action (second locking portion 126) is smaller than the distance (x1+x2) of the first fixing portion 110, the user is given a different tactile sensation from that of the first fixing portion 110. That is, the wiring / piping material support 100 is intended to give the user a different operational sensation or tactile sensation when fixing to the first suspension bolt 11 and the second suspension bolt 13, respectively, and can thereby provide the user with the awareness of an operational error or the like. In this way, the wiring / piping material support 100 is fixed to the second suspension bolt 13 via the second fixing portion 120.

[0062] Finally, the second support structure 10B can be constructed by dropping the wiring / piping material 15 onto the support surface 104 through the introduction portion 106 of the support portion 103 for the wiring / piping material support 100 fixed to the second hanging bolt 13.

[0063] That is, regardless of whether the first fixing portion 110 or the second fixing portion 120 is used for the first hanging bolt 11 and the second hanging bolt 13 having different diameters, the wiring / piping material support 100 can be fixed to the hanging bolts by the same installation operation. Furthermore, since the positional relationship between each fixing portion 110, 120 and the support portion 103 is the same in the first and second support structures 10A and 10B, the height position of the support surface 104 of the support portion 103 relative to the hanging bolts 11, 13 can be the same regardless of which fixing portion 110 or 120 is used. Furthermore, since the pair of support portions 103 extend on both sides of the base portion 101, the support portions 103 for two paths can be installed simultaneously by a single installation operation.

[0064] Hereinafter, the operation and effect of the wiring / piping material support 100 and the fixing portion structure according to one embodiment of the present invention will be described.

[0065] According to the wiring / piping material support 100 of this embodiment, the base 101 fixed to the hanging bolts 11 and 13 is provided with two fixing parts consisting of the first fixing part 110 and the second fixing part 120, and the first opening 112 and the second opening 122 are opened so as to face opposite each other in the width direction perpendicular to the extension direction of the support part 103. In this way, by providing the openings 112 and 122 of the fixing parts 110 and 120 perpendicular to the extension direction of the support part 103, it is possible to form the first fixing part 110 and the second fixing part 120 on the inside in the width direction of the support part 103 without interfering with it. The first and second fixing parts 110 and 120 are configured to hold the axial centers of the first and second hanging bolts 11 and 13 at positions overlapping with the support part 103 in the width direction, respectively. That is, regardless of which of the two fixing parts 110, 120 is fixed to the hanging bolts 11, 13, the axis of the fixed hanging bolts 11, 13 is located within the width direction range of the support part 103. This makes it possible to effectively transmit the load that the support part 103 receives from the wiring / piping material 15 to the hanging bolts 11, 13 via the fixing parts 110, 120. Therefore, the wiring / piping material support 100 of this embodiment enables stable support of the wiring / piping material 15.

[0066] In addition, when the wiring / piping material is fixed using only the clamping portion as in the conventional method (Patent Document 1), if the wiring / piping material fastened to the support portion is pulled in the opposite direction to the opening direction of the clamping portion, it may easily come off (second problem). In contrast, according to the fixing portion structure of the second fixing portion 120 of the wiring / piping material support 100 of this embodiment, the axial distance y2 between the second locking portion 126 and the support portion 103 is greater than the axial distance x2 between the second abutting portion 125 and the support portion 103, so that the second abutting portion 125, which is closer to the support portion 103 than the second locking portion 126, can preferentially receive the load of the tensile load in the longitudinal direction (laying direction) of the supported wiring / piping material 15. Then, the posture of the entire wiring / piping material support 100 is less likely to be displaced in the direction in which the second hanging bolt 13 comes out of the second locking portion 126, and as a result, the wiring / piping material support 100 is effectively prevented from coming off the second hanging bolt 13. Therefore, the fixing portion structure of this embodiment enables the wiring / piping material support 100 to stably support the wiring / piping material 15 .

For example, the diameters of the first hanging bolt and the second hanging bolt may be the same. Also, only the positions of the abutting parts may differ between the first fixing part and the second fixing part. In that case, the user can select which one to use depending on the operability of the first fixing part and the second fixing part. Alternatively, the first fixing part and the second fixing part may be configured exactly the same.

[0069] (2) The wiring / piping material support of the present invention is not limited to the above embodiment. In the above embodiment, the wiring / piping material support is provided with a pair of support parts, but only one support part may be provided. In addition, the base and the support part may be formed in any shape different from the above embodiment.

[0070] (3) The wiring / piping material support of the present invention is not limited to the above embodiment. In the above embodiment, the axial distance between the locking portion and the support portion is larger than the axial distance between the abutting portion and the support portion only in the second fixing portion, but the present invention is not limited to this. That is, the axial distance between the locking portion and the support portion may be larger than the axial distance between the abutting portion and the support portion in both the first fixing portion and the second fixing portion. Alternatively, the axial distance between the locking portion and the support portion may be smaller than or the same as the axial distance between the abutting portion and the support portion in both the first fixing portion and the second fixing portion.

[0071] (4) The present invention is not limited to the above embodiment. When the fixing portion structure of the present invention is provided on a wiring / piping material support, only one fixing portion may be provided on the base instead of two fixing portions. That is, the wiring / piping material support may include one fixing portion having the fixing portion structure.
