[0004] [Patent Document 1] Japanese Patent Publication No. 2020-94618 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the invention disclosed in Patent Document 1 has a problem in that there is room for improvement in resistance when a pulling force is applied to the clamping tool.

[0006] An object of the present invention is to provide a clamping device that is less likely to come off when a pulling force is applied. [Means for solving the problem]

[0007] The present invention will be described with reference to the drawings. The reference numerals in the drawings are used in this section to facilitate understanding of the invention. The reference numerals in the drawings are not intended to limit the invention to the scope of the drawings.

[0008] To achieve the above-described object, according to one aspect of the present invention, a clamping device 10 includes a base portion 22 and an attachment portion 24. The attachment portion 24 is provided on the base portion 22. The attachment portion 24 protrudes from the base portion 22. The attachment portion 24 attaches the base portion 22 to a predetermined member 240. A through-hole 262 is formed in the predetermined member 240. The attachment portion 24 includes a support portion 40 and a retaining portion 42. The support portion 40 has a base 60 connected to the base portion 22, a tip portion 62, and a side portion 64 formed between the base 60 and the tip portion 62. The retaining portion 42 branches off from a through-section 80 of the side portion 64 of the support portion 40. When the tip portion of the support portion 40 passes through the through-hole 262, the through-section 80 passes through the through-hole 262 together with the tip portion 62. The clamping device 10 further includes a drawing portion 26. The pulling portion 26 is positioned closer to the base portion 22 than the through-section 80. When the tip portion 62 and the through-section 80 pass through the through-hole 262 and the retaining portion 42 catches on the edge of the through-hole 262, the pulling portion 26 pulls the retaining portion 42 toward the base portion 22. The mounting portion 24 further has a different-direction protruding portion 44. The different-direction protruding portion 44 protrudes from a protruding portion 82 in the through-section 80 of the support portion 40. The protruding portion 82 is a location different from the location where the retaining portion 42 branches off. The different-direction protruding portion 44 protrudes in a direction different from the direction in which the retaining portion 42 is located.

[0009] When the retaining portion 42 branches off from the through-section 80 of the support portion 40 and the anterior-direction protruding portion 44 protrudes from the protruding portion 82 of the through-section 80, the clamping device 10 becomes difficult to remove even when a pulling force is applied to the clamping device 10 in a direction that would cause it to come off the specified member 240. This is because the anterior-direction protruding portion 44 acts as an obstacle. As a result, the clamping device 10 is less likely to come off when a pulling force is applied.

[0010] The different direction protruding portion 44 has a plate-shaped portion 100 and a fixing bar portion 102. do. The plate-shaped portion 100 protrudes from the protruding portion 82 in a direction different from the direction in which the retaining portion 42 is located. The fixing bar portion 102 protrudes from the protruding portion 82 in the same direction as the plate-shaped portion. The fixing bar portion 102 is fixed to the plate-shaped portion 100.

[0011] The fixing bar 102 projects from the protruding portion 82 in the same direction as the plate-shaped portion 100. The fixing bar 102 is fixed to the plate-shaped portion 100. As a result, the plate-shaped portion 100 is reinforced by the fixing bar 102. Because the plate-shaped portion 100 projecting from the protruding portion 82 is reinforced, when a pull-out force is applied to the clamping device 10 in a direction that would cause it to come out of the specified member 240, the different-direction protruding portion 44 is able to resist the pull-out force. Because it is able to resist the pull-out force, even if a pull-out force is applied to the clamping device 10 in a direction that would cause it to come out of the specified member 240, the clamping device 10 is less likely to come out. As a result, the possibility of it coming out when a pull-out force is applied is reduced.

[0012] Alternatively, it is desirable that the aforementioned retaining portion 42 extends in the direction of the base portion 22 and the pulling portion 26 as viewed from the through section 80. In this case, it is desirable that the plate-like portion 100 extends along a direction perpendicular to the direction from the base 60 of the support portion 40 to the tip portion 62. In this case, it is desirable that the fixing bar portion 102 extends along the direction from the base 60 of the support portion 40 to the tip portion 62. Stretch It is desirable that

[0013] The plate-like portion 100 extends in a direction perpendicular to the direction from the base 60 of the support portion 40 to the tip 62, while the fixed bar portion 102 extends in a direction from the base 60 of the support portion 40 to the tip 62. Stretch As a result, the fixing bar 102 StretchThe plate-shaped portion 100 is more strongly reinforced than when the direction of extension is the same as the direction of expansion of the plate-shaped portion 100. Because the plate-shaped portion 100 protruding from the protruding portion 82 is strongly reinforced, when a pulling force is applied to the clamping device 10 in a direction that would cause it to come out of the specified member 240, the different-direction protruding portion 44 can strongly resist the pulling force. Because it is possible to strongly resist the pulling force, even when a pulling force is applied to the clamping device 10 in a direction that would cause it to come out of the specified member 240, the clamping device 10 is less likely to come out. As a result, the possibility of coming out when a pulling force is applied is reduced.

[0014] Alternatively, it is desirable that the fixed rail portion 102 described above has a base-facing rail portion 120 and a back rail portion 122. The base-facing rail portion 120 is fixed to the plate-shaped portion 100 on a surface of the plate-shaped portion 100 that faces the base portion 22. The back rail portion 122 is fixed to the plate-shaped portion 100 on a back surface thereof when viewed from the surface of the plate-shaped portion 100 that faces the base portion 22. In addition, it is desirable that the fixed rail portion 102 further includes the following portion 121. The portion 121 is disposed between the base opposing rail portion 120 and the rear rail portion 122. The portion 121 is integrally connected to the base opposing rail portion 120 and the rear rail portion 122. The portion 121 is fixed to the plate-shaped portion 100.

[0015] Since the fixed bar 102 has the base-facing bar 120 and the back bar 122, the plate-shaped part 100 is more strongly reinforced than when the fixed bar 102 has only one of these. As a result, the plate-shaped part 100 is less likely to come off when a pulling force is applied.

[0016] Alternatively, it is desirable that the width of the rear rail portion 122 in a direction perpendicular to the direction from the base 60 to the tip 62 of the support portion 40 described above becomes wider as it approaches the plate-shaped portion 100.

[0017] When the width of the rear rail portion 122 described above increases as it approaches the plate-shaped portion 100, the cross-sectional area of ​​the rear rail portion 122 increases compared to when the width does not increase. When the cross-sectional area of ​​the rear rail portion 122 increases, it is possible to mitigate the reduction in mechanical strength of the rear rail portion 122 that occurs when the protruding height of the rear rail portion 122 from the plate-shaped portion 100 is reduced. As a result, it is possible to reduce the protruding height of the rear rail portion 122 from the plate-shaped portion 100, and it is less likely to come off when a pull-out force is applied. [Effects of the Invention]

[0018] According to the present invention, the possibility of coming off when a pulling force is applied is reduced. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are the same. Therefore, detailed descriptions thereof will not be repeated.

[0021] [Clamp configuration] Fig. 1 is an overall view of a clamping device 10 according to this embodiment. The configuration of the clamping device 10 according to this embodiment will be described based on Fig. 1.

[0022] The clamp device 10 according to this embodiment is attached to a predetermined metal fitting 240, which will be described later. This metal fitting 240 has a through hole 262 formed therein. The clamp device 10 attached to this metal fitting 240 bundles various objects, such as a wire harness (not shown), and the objects are fixed to the metal fitting 240.

[0023] The clamping device 10 according to this embodiment includes a binding portion 20, a base portion 22, an attachment portion 24, and a pair of gathering portions 26, 26.

[0024] The binding portion 20 bundles various items such as the wire harness described above. The base portion 22 serves as the foundation of the clamping device 10 according to this embodiment. An end of the binding portion 20 is fixed to the base portion 22. The mechanism for this fixation is well known, so a detailed description thereof will not be repeated here. In this embodiment, the mounting portion 24 is provided on the base portion 22. The mounting portion 24 protrudes from the base portion 22. The mounting portion 24 attaches the base portion 22 to a metal fitting 240. In this embodiment, the pair of drawing portions 26, 26 protrude from both sides of the base portion 22. The tip of the drawing portion 26 is closer to the side where the mounting portion 24 is located than its base. The drawing portion 26 draws the mounting portion 24 toward the base portion 22.

[0025] Fig. 2 is a front view of the base portion 22, the attachment portion 24, and the gathering portions 26, 26 according to this embodiment. Fig. 3 is a perspective view of the base portion 22, the attachment portion 24, and the gathering portions 26, 26 according to this embodiment, on the side of the different-direction protruding portion 44. Fig. 4 is a perspective view of the base portion 22, the attachment portion 24, and the gathering portions 26, 26 according to this embodiment, on the side opposite to the different-direction protruding portion 44. These configurations according to this embodiment will be described with reference to Figs. 2 to 4.

[0026] The mounting portion 24 according to this embodiment includes a support portion 40, a pair of retaining portions 42, 42, and a different-direction protruding portion 44.

[0027] The support portion 40 has a base 60 connected to the base portion 22 , a tip portion 62 , and a side portion 64 formed between the base 60 and the tip portion 62 .

[0028] The retaining portion 42 branches off from the through-section 80 of the side surface portion 64 of the support portion 40. The through-section 80 is a section that passes through the through-hole 262 together with the tip portion 62 of the support portion 40 when the tip portion 62 passes through the through-hole 262. For this reason, the aforementioned drawing portion 26 is disposed closer to the base portion 22 than the through-section 80. As is particularly clear in FIG. 2 , the retaining portion 42 extends in the direction of the base portion 22 and the drawing portion 26 when viewed from the through-section 80.

[0029] The different-direction protruding portion 44 protrudes from a protruding point 82 in the through section 80 of the support portion 40. The protruding point 82 is a point different from the point where the retaining portion 42 branches off. The different-direction protruding portion 44 protrudes in a direction different from the direction in which the retaining portion 42 is located.

[0030] 5 is a perspective view of the vicinity of the different-direction protruding portion 44 according to this embodiment. The configuration of the different-direction protruding portion 44 according to this embodiment will be described with reference to FIGS.

[0031] The different direction protruding portion 44 according to this embodiment has a plate-shaped portion 100 and a pair of fixed bar portions 102, 102. The plate-shaped portion 100 protrudes from the protruding portion 82 in a direction different from the direction in which the retaining portion 42 is located. In this embodiment, the plate-shaped portion 100 extends along a direction perpendicular to the direction from the base 60 of the support portion 40 toward the tip portion 62. The fixed bar portion 102 protrudes from the protruding portion 82 in the same direction as the plate-shaped portion 100. The fixed bar portion 102 extends along the direction from the base 60 of the support portion 40 toward the tip portion 62. Stretch As will be described later, the binding portion 20, base portion 22, attachment portion 24, and pair of gathering portions 26, 26 of the clamping device 10 according to this embodiment are integrated. Therefore, the fixing bar portion 102 is fixed to the plate-like portion 100.

[0032] The fixed rail 102 according to this embodiment has a base-facing rail 120 and a back rail 122. The base-facing rail 120 is fixed to the plate-shaped portion 100 at a surface of the plate-shaped portion 100 facing the base portion 22. As is particularly clear from FIGS. 2, 3, and 5, in this embodiment, the width of the base-facing rail 120 in a direction perpendicular to the direction from the base 60 of the support portion 40 to the tip 62 increases toward the plate-shaped portion 100. The back rail 122 is fixed to the plate-shaped portion 100 at a back surface thereof as viewed from the surface of the plate-shaped portion 100 facing the base portion 22. As is particularly clear from FIGS. 2, 4, and 5, in this embodiment, the width of the back rail 122 in a direction perpendicular to the direction from the base 60 of the support portion 40 to the tip 62 increases toward the plate-shaped portion 100. In addition, the fixed rail portion 102 according to this embodiment further includes a portion 121, which will be described below. The portion 121 is disposed between the base facing rail portion 120 and the rear rail portion 122. The portion 121 is integrally connected to the base facing rail portion 120 and the rear rail portion 122. The portion 121 is fixed to the plate-shaped portion 100.

[0033] [Method of manufacturing clamping tool] The clamping device 10 according to this embodiment is manufactured by injection molding. That is, the clamping device 10 according to this embodiment is manufactured by injecting synthetic resin into a mold (not shown) for forming the clamping device 10. As a result, the binding portion 20, base portion 22, mounting portion 24, and pair of gathering portions 26, 26 according to this embodiment are integrated into one piece.

[0034] [How to use the clamp] Figure 6 shows the clamping device 10 according to this embodiment being attached to a metal fitting 240. In this embodiment, this metal fitting 240 is used to attach a wire harness or other long material to an H-beam or other steel material. A through-hole 262 is formed in this metal fitting 240. Most of the binding portion 20 and most of the retaining portion 42 are not shown in Figure 6. A method of using the clamping device 10 according to this embodiment will be described with reference to Figure 6.

[0035] The worker inserts the mounting portion 24 of the clamping device 10 according to this embodiment into the through-hole 262. In doing so, the worker first inserts the anisotropic protruding portion 44 into the through-hole 262. As a result, the anisotropic protruding portion 44 passes through the through-hole 262. Next, the worker inserts the through-section 80 of the support portion 40 and the pair of retaining portions 42, 42 into the through-hole 262. As a result, the through-section 80 of the support portion 40 and the pair of retaining portions 42, 42 enter the through-hole 262. This situation is shown in FIG. 6. As the pair of retaining portions 42, 42 enter the through-hole 262, the pair of retaining portions 42, 42 are pushed by the edge of the through-hole 262 and bend.

[0036] The worker continues to push the clamping device 10 according to this embodiment into the through-hole 262. As a result, the pair of drawing portions 26, 26 slides on the outer peripheral surface of the predetermined metal fitting 240. As the pair of drawing portions 26, 26 slides on the outer peripheral surface of the predetermined metal fitting 240, the pair of drawing portions 26, 26 bends.

[0037] The worker further pushes the clamping device 10 according to this embodiment into the through-hole 262. As a result, the pair of retaining portions 42, 42 comes out of the through-hole 262, and the bent retaining portions 42, 42 try to return to their original shape. Meanwhile, as the pair of drawing portions 26, 26 slides on the outer peripheral surface of the metal fitting 240 in the groove, the pair of drawing portions 26, 26 bends further.

[0038] When the pair of retaining portions 42, 42 passes through the through hole 262, the worker releases the clamping device 10 according to this embodiment. This causes the pair of bent drawing portions 26, 26 to return to their original shape. As the pair of drawing portions 26, 26 return to their original shape, the anisotropic protruding portion 44 and the retaining portions 42, 42 are drawn toward the base portion 22. In this manner, when the mounting portion 24 is inserted into the through hole 262 and the retaining portions 42, 42 catch on the edge of the through hole 262, the drawing portions 26, 26 draw the retaining portions 42, 42 toward the base portion 22. When the retaining portions 42, 42 are drawn toward the base portion 22, attachment of the clamping device 10 according to this embodiment to the predetermined metal fitting 240 is completed. The worker then bundles a long object (not shown) using the bundling portion 20.

[0039] [Effects of the clamping device according to this embodiment] In the clamping device 10 according to this embodiment, the retaining portion 42 branches off from the through-section 80 of the support portion 40, and the different-direction protruding portion 44 protrudes from a protruding portion 82 of the through-section 80. The protruding different-direction protruding portion 44 makes it difficult for the clamping device 10 to come off even if a pulling force is applied to the clamping device 10 in a direction that would cause it to come off from the metal fitting 240. As a result, the possibility of coming off when a pulling force is applied is reduced.

[0040] Furthermore, in the clamping device 10 according to this embodiment, the plate-like portion 100 is reinforced by the fixing bar portion 102. This makes it difficult for the clamping device 10 to come off even if a pulling force is applied to the clamping device 10 in a direction that would cause it to come off the predetermined metal fitting 240.

[0041] In this embodiment, the plate-like portion 100 extends in a direction perpendicular to the direction from the base 60 of the support portion 40 to the tip 62, whereas the fixed bar portion 102 extends in a direction from the base 60 of the support portion 40 to the tip 62. Stretch As a result, the fixing bar 102 Stretch The plate-shaped portion 100 is more strongly reinforced than when the direction of extension is the same as the direction of expansion of the plate-shaped portion 100. As a result, there is a lower possibility of the plate-shaped portion 100 coming out when a pulling force is applied.

[0042] Furthermore, in this embodiment, the fixed bar 102 has the base-facing bar 120 and the back bar 122, so the plate-shaped part 100 is more strongly reinforced than when the fixed bar 102 has only one of these. As a result, there is a lower possibility that the plate-shaped part 100 will come off when a pulling force is applied.

[0043] Furthermore, in this embodiment, the width of the rear rail portion 122 increases as it approaches the plate-shaped portion 100. This increases the cross-sectional area of ​​the rear rail portion 122 compared to when the width does not increase. Increasing the cross-sectional area of ​​the rear rail portion 122 can mitigate the reduction in mechanical strength of the rear rail portion 122 that occurs when the protruding height of the rear rail portion 122 from the plate-shaped portion 100 is reduced. As a result, the protruding height of the rear rail portion 122 from the plate-shaped portion 100 can be reduced, and the possibility of the rear rail portion 122 coming out when a pulling force is applied is reduced.

[0044] [Description of Modifications] The embodiments disclosed herein are examples in all respects. The scope of the present invention is not limited to the above-described embodiments. Of course, various design changes may be made without departing from the spirit of the present invention.

[0045] For example, the shape of the different direction protrusion 44 is not limited to the above. . solid The fixed bar portion 102 may have only one of the base facing bar portion 120 and the rear bar portion 122. There are no particular limitations on the shapes of the base facing bar portion 120 and the rear bar portion 122. The direction in which the plate-shaped portion 100 expands does not have to be perpendicular to the direction from the base 60 of the support portion 40 toward the tip portion 62.

[0046] Furthermore, the member to which the clamping device of the present invention is attached is not limited to the above-described metal fitting 240. Examples of such members include a channel steel with a through-hole 262 formed therein, a section material with a through-hole 262 formed therein (in this case, "section material" refers to a long material with a predetermined cross-sectional shape), and a plate material with a through-hole 262 formed therein.
