DETAILED DESCRIPTION OF THE INVENTION

[0009] (Overview) The fixture of the present embodiment is used when attaching a support object to a fixation object. The fixture is fixed to the fixation object by a fixing element that is driven out from a tool toward the fixation object or a fixing element that is screwed into the fixation object, for example. The tool may be any of those that operate pneumatically, those that operate by the rotational force of an electric motor, and those that are manually operated by an operator. The fixture of the present embodiment is described based on FIGS. 1A, 1B, 2, 3, 4, 5, 6A, 6B, and 7.

[0010] An example of a fixture, an insert clip 10, is for attaching a long tubular body 11, which is an example of an object to be supported, to a fixed object 12. The tubular body 11 can also be regarded as a long object. The fixed object 12 can be any of building structures such as columns, foundations, walls, floors, roof slabs, trusses, beams, etc. The insert clip 10 may be defined as a gacha band or a saddle band. The tubular body 11 is, for example, made of synthetic resin and has flexibility. The tubular body 11 is, for example, a corrugated pipe covering a cable or a pipe wrapped with urethane foam. The outer peripheral surface shape of the tubular body 11 shown in FIGS. 4(B) and 5 is, for example, substantially circular in a plane perpendicular to the center line A1. The center line A1 is an imaginary line passing through the center of the tubular body 11, and the center line A1 is arranged along the first direction B1.

[0011] The insert clip 10 is integrally formed of synthetic resin, for example, thermoplastic resin or thermosetting resin. The thermoplastic resin or thermosetting resin may be any of PA6 (nylon: polyamide synthetic resin), PP (polypropylene), PE (polyethylene), etc. The insert clip 10 has a main body portion 13, a projecting portion 14, a rising portion 15, a hinge 16, a first arm portion 17, and a second arm portion 18. The main body portion 13 is a portion that comes into contact with and is fixed to the fixed object 12. The main body portion 13 can also be regarded as a base portion. The projecting portions 14 are provided so as to project from both sides of the main body portion 13, respectively.

[0012] The main body portion 13 has a plate portion 70. The plate portion 70 extends along the first direction B1 when the main body portion 13 is placed on the fixed object 12. The plate portion 70 has a first surface 19 shown in FIG. 1A and a second surface 20 shown in FIG. 1B. As shown in FIG. 2, the first surface 19 and the second surface 20 are arranged in parallel. When the main body 1 is placed on the fixed object 12, the first surface 19 exists at a position opposite to the fixed object 12. Wall portions 21, 22 are provided so as to project from the first surface 19. The heights at which the wall portions 21, 22 project from the first surface 19 are the same.

[0013] As shown in FIG. 1, when the insert clip 10 is viewed in plan view, the wall portions 21, 22 are circular. The wall portion 21 is arranged around the position D1, and the wall portion 22 is arranged around the position D2. The position D1 and the position D2 exist at different positions on the first surface 19. That is, the position D1 and the position D2 are arranged at intervals in the first direction B1. The outer peripheral surfaces of the wall portion 21 and the wall portion 22 are not in contact with each other.

[0014] The inner peripheral surface 21A of the wall portion 21 is inclined with respect to the virtual line E1. The virtual line E1 is a straight line arranged along the thickness direction C1 of the insert clip 10. In the plan view of the insert clip 10, the virtual line E1 and the position D1 are at the same position. Specifically described, the inner peripheral surface 21A is provided with a taper in the direction in which the inner diameter φ1 increases as it approaches the tip of the wall portion 21 from the plate portion 70.

[0015] Further, the support portion 23 is provided so as to protrude from the first surface 19. The height at which the support portion 23 protrudes from the first surface 19 is the same as the height at which the wall portion 21 protrudes from the first surface 19. The support portion 23 is provided around the virtual line E1. As shown in FIG. 1A, in a plan view perpendicular to the virtual line E1, the outer peripheral shape of the support portion 23 is circular. Also, as shown in FIG. 2, in the front cross section in the direction along the virtual line E1, the outer peripheral surface 23A of the support portion 23 is inclined with respect to the virtual line E1. Specifically described, the outer peripheral surface 23A is provided with a taper in the direction in which the outer diameter φ2 decreases as it approaches the tip of the support portion 23 from the plate portion 70.

[0016] A recess 25 is formed between the wall portion 21 and the support portion 23. The recess 25 is annularly arranged around the virtual line E1. Also, the mounting hole 24 is provided so as to penetrate the plate portion 70, the support portion 23, and the convex portion 29. The mounting hole 24 is provided around the virtual line E1.

[0017] The mounting hole 24 is provided to allow the fixing element 31 for fixing the insert clip 10 to the object 12 to enter. The recess 25 is a space provided to drive or screw in the fixing element 31 into the object 12, or to allow a part of a tool, for example, the nose portion 54 shown in FIG. 2 to enter. The inner peripheral surface 21A of the wall portion 21 and the outer peripheral surface 23A of the support portion 23 are provided to position a part of a tool for driving or screwing in the fixing element 31 into the object 12, for example, the nose portion 54 shown in FIG. 2, with respect to the main body portion 13. More specifically described, the inner peripheral surface 21A and the outer peripheral surface 23A of the support portion 23 are provided to position the center line of the nose portion 54 and the virtual line E1 of the mounting hole 24 substantially coaxially, that is, concentrically, during the operation of fixing the insert clip 10 to the object 12.

[0018] The inner peripheral surface 22A of the wall portion 22 is inclined with respect to the virtual line E2. The virtual line E2 is a straight line arranged along the thickness direction C1 of the insert clip 10. In the plan view of the insert clip 10, the virtual line E2 and the position D2 are at the same position. More specifically described, the inner peripheral surface 22A is provided with a taper in the direction in which the inner diameter φ3 expands as it approaches the tip of the wall portion 22 from the plate portion 70. The minimum value of the inner diameter φ1 and the minimum value of the inner diameter φ3 are the same. The maximum value of the inner diameter φ1 and the maximum value of the inner diameter φ3 are the same.

[0019] Further, the support portion 26 is provided so as to protrude from the first surface 19. The height by which the support portion 26 protrudes from the first surface 19 is the same as the height by which the wall portion 22 protrudes from the first surface 19. The support portion 26 is provided around the virtual line E2. As shown in FIG. 1A, in a plan view perpendicular to the virtual line E2, the outer peripheral shape of the support portion 26 is circular. Also, as shown in FIG. 2, in the front cross section in the direction along the virtual line E2, the outer peripheral surface 26A of the support portion 26 is inclined with respect to the virtual line E2. More specifically, the outer peripheral surface 26A is provided with a taper in the direction in which the outer diameter φ4 decreases as approaching from the plate portion 70 to the tip of the support portion 26. The minimum value of the outer diameter φ2 and the minimum value of the outer diameter φ4 are the same. The maximum value of the outer diameter φ2 and the maximum value of the outer diameter φ4 are the same. Further, a recess 27 is formed between the wall portion 22 and the support portion 26. The recess 27 is annularly arranged around the virtual line E2.

[0020] Also, the mounting hole 28 is provided so as to penetrate the plate portion 70, the support portion 26, and the convex portion 29. The mounting hole 28 is provided around the virtual line E2. The inner diameter of the mounting hole 24 and the inner diameter of the mounting hole 28 are the same. The mounting hole 28 is provided to allow the fixing element 31 for fixing the insert clip 10 to the fixing object 12 to enter. The recess 27 is a space provided to allow the fixing element 31 to be driven into the fixing object 12 or to allow a part of the tool for screwing, that is, the nose portion 54 shown in FIG. 2 to enter. The fixing element 31 may have a shaft portion, and for example, may be any of a bolt, a screw, and a nail. The nose portion 54 of the tool for bolts and screws has a cylindrical shape. The tool for hitting a nail is a hammer (not shown).

[0021] The inner peripheral surface 22A of the wall portion 22 and the outer peripheral surface 26A of the support portion 26 are provided to position the nose portion 54 shown in FIG. 2 with respect to the main body portion 13. More specifically, the inner peripheral surface 22A and the outer peripheral surface 26A of the support portion 26 are provided to position the center line of the nose portion 54 and the virtual line E2 of the mounting hole 28 substantially coaxially, that is, concentrically during the operation of fixing the insert clip 10 to the fixing object 12.

[0022] As shown in FIGS. 1B and 2, a convex portion 29 protruding from the second surface 20 is provided. The convex portion 29 is provided over a region including virtual lines E1 and E2 in a bottom view of the insert clip 10. The mounting hole 24 penetrates through the support portion 23, the plate portion 70, and the convex portion 29. The mounting hole 28 penetrates through the support portion 26, the plate portion 70, and the convex portion 29. Further, an outer peripheral wall 30 protruding from the second surface 20 and the protruding portion 14 is provided. The height of the convex portion 29 protruding from the second surface 20 and the height of the outer peripheral wall 30 protruding from the second surface 20 are the same. In a bottom view of the insert clip 10, the outer peripheral wall 30 is annularly arranged, and the convex portion 29 is arranged inside the outer peripheral wall 30. A concave portion 60 is formed between the outer peripheral wall 30 and the convex portion 29.

[0023] When the insert clip 10 is viewed in plan as shown in FIG. 1A, the protruding portion 14 extends along a second direction B2 that intersects the first direction B1 with respect to the main body portion 13. The first direction B1 is a direction along a straight line (not shown) passing through positions D1 and D2. The angle between the first direction B1 and the second direction B2 is approximately 90 degrees. Two protruding portions 14 are provided. When the insert clip 10 is viewed in plan as shown in FIG. 1A, in the second direction B2, the wall portion 21, the support portion 23, and the mounting hole 24 are arranged between the two protruding portions 14. Further, in the second direction B2, the wall portion 22, the support portion 26, and the mounting hole 28 are arranged at positions deviated from between the two protruding portions 14.

[0024] As shown in FIG. 4(B), the rising portions 15 are respectively connected to the two protruding portions 14. The two rising portions 15 extend in a direction perpendicular to the protruding portions 14. In the thickness direction C1 of the main body portion 13, the lengths by which the two rising portions 15 extend from the protruding portions 14 are the same. The main body portion 13 and the two protruding portions 14 are arranged between the two rising portions 15.

[0025] As shown in FIG. 4(B), the first arm portion 17 is connected to one rising portion 15 via a hinge 16. As shown in FIG. 1, the first arm portion 17 is a belt-like body having a predetermined width in the direction along the first direction B1. The first arm portion 17 is curved in a substantially arc shape as shown in FIG. 4(B) in a state where no external force is applied. The first arm portion 17 has an outer surface 40 located on the outer side in the bending direction and an inner surface 41 located on the inner side in the bending direction. The hinge 16 is connected to the outer surface 40. The first arm portion 17 has an end portion 42 and an end portion 43 at both ends. An engaging portion 44 is provided on the inner surface 41 of the first arm portion 17. A plurality of engaging portions 44 are provided between the end portion 42 and the end portion 43.

[0026] As shown in FIG. 4(B), the second arm portion 18 is connected to one rising portion 15 via a hinge 16. As shown in FIG. 1, the second arm portion 18 is a belt-like body having a predetermined width in the direction along the first direction B1. The second arm portion 18 is curved in a substantially arc shape as shown in FIG. 4(B) in a state where no external force is applied. The second arm portion 18 has an outer surface 45 located on the outer side in the bending direction and an inner surface 55 located on the inner side in the bending direction. The hinge 16 is connected to the outer surface 45. The second arm portion 18 has an end portion 46 and an end portion 47 at both ends. An engaging portion 48 is provided on the outer surface 45 of the second arm portion 18. A plurality of engaging portions 48 are provided between the end portion 46 and the end portion 47.

[0027] (Usage Examples and Effects) The operator fixes the insert clip 10 to the object 12 to be fixed as follows. First, the convex portion 29 and the outer peripheral wall 30 of the main body portion 13 are brought into contact with the mounting surface 53 of the object 12 to be fixed. Also, as shown in FIG. 4(B), the first arm portion 17 and the second arm portion 18 are separated. Then, as shown in FIG. 2, the nose portion 54 of the tool is inserted into the recess 25, and the fixing element 31 is inserted into the mounting hole 24 and made to bite into the object 12 to be fixed. Here, an example in which the outer diameter R2 of the nose portion 54 is less than the minimum value of the inner diameter φ1 of the inner peripheral surface 21A will be described. Then, the inner peripheral surface of the nose portion 54 having the inner diameter R1 is brought into contact with the outer peripheral surface 23A of the support portion 23. For this reason, even when nose portions 54 having different inner diameters R1 are used, the center line of the nose portion 54 is positioned with respect to the virtual line E2 of the mounting hole 24.

[0028] Also, the nose portion 54 of the tool is inserted into the recess 27, and the fixing element 31 is inserted into the mounting hole 28 and made to bite into the object 12 to be fixed. Here, an example in which the outer diameter R2 of the nose portion 54 is less than the minimum value of the outer diameter φ4 of the inner peripheral surface 22A will be described. Then, the inner peripheral surface of the nose portion 54 having the inner diameter R1 is brought into contact with the outer peripheral surface 26A of the support portion 26. For this reason, even when nose portions 54 having different inner diameters R1 are used, the center line of the nose portion 54 is positioned with respect to the virtual line E2 of the mounting hole 28.

[0029] Next, an example in which the inner diameter R1 of the nose portion 54 exceeds the maximum value of the outer diameter φ2 of the outer peripheral surface 23A will be described. Then, the outer peripheral surface of the nose portion 54 having the outer diameter R2 is brought into contact with the inner peripheral surface 21A. For this reason, even when nose portions 54 having different outer diameters R2 are used, the center line of the nose portion 54 is positioned with respect to the virtual line E1 of the mounting hole 24.

[0030] Further, the nose portion 54 of the tool is inserted into the concave portion 27, and the fixing element 31 is inserted into the mounting hole 28 and bitten into the object 12 to be fixed. Here, an example will be described in which the inner diameter R1 of the nose portion 54 exceeds the maximum value of the outer diameter φ4 of the outer peripheral surface 26A. Then, the outer peripheral surface of the nose portion 54 having the outer diameter R2 is brought into contact with the inner peripheral surface 22A. Therefore, even when the nose portion 54 having different outer diameters R2 is used, the center line of the nose portion 54 is positioned with respect to the virtual line E2 of the mounting hole 28.

[0031] In this way, the inner peripheral surface 21A of the wall portion 21 and the outer peripheral surface 23A of the support portion 23 serve to position the nose portion 54 with respect to the mounting hole 24. Further, the inner peripheral surface 22A of the wall portion 22 and the outer peripheral surface 26A of the support portion 26 serve to position the nose portion 54 with respect to the mounting hole 28. Therefore, the fixing element 31 can be accurately inserted into the mounting holes 24 and 28, and the insert clip 10 can be securely fixed to the object 12 to be fixed.

[0032] Further, the support portions 23 and 26 are elastically deformed by receiving loads such as the pressing force applied from the head portion 31A of the fixing element 31 and the impact force by a tool (such as a hammer). Therefore, the load received by the plate portion 70 can be reduced, and cracking, breakage, etc. of the plate portion 70 can be suppressed. Further, the support portions 23 and 26 serve as the fixing element 31, serve to position the nose portion 54 with respect to the mounting hole 24, and serve to position the nose portion 54 with respect to the mounting hole 28. Therefore, it is not necessary to separately provide structures for the insert clip 10 to perform each role, and the structure of the insert clip 10 can be simplified.

[0033] Furthermore, the insert clip 10 can also be fixed to the object 12 to be fixed using an adhesive. In this case, an adhesive is interposed between the wall portions 21 and 22 and the convex portion 29 and the object 12 to be fixed, and the insert clip 10 is fixed to the object 12 to be fixed by the solidification of the adhesive. Note that the adhesive may be present in the concave portion 60.

[0034] Next, the operation of holding the tubular body 11 in the insert clip 10 will be described. As shown in FIG. 4(B), the end portion 42 and the end portion 46 are separated, and all of the engaging portion 44 and the engaging portion 48 are released. The operator moves the tubular body 11 in the thickness direction, passes the tubular body 11 between the end portion 42 and the end portion 46, and enters the tubular body 11 into the space G1 between the first arm portion 17 and the second arm portion 18. Then, the tubular body 11 is pressed against the end portion 43, the hinge 16 is elastically deformed, and the end portion 43 is pressed against the end portion 47.

[0035] For this reason, the hinge 16 of the second arm portion 18 is elastically deformed, and the end portion 42 and the end portion 46 approach each other. When the tubular body 11 is further brought closer to the main body portion 13, the end portion 43 and the end portion 47 are pushed apart by the tubular body 11, and a part of the tubular body 11 enters between the end portion 43 and the end portion 47. Then, as shown in FIG. 5, the tubular body 11 contacts the main body portion 13, a part of the tubular body 11 enters into the space G1 surrounded by the two rising portions 15 and the main body portion 13, and the tubular body 11 stops. Further, since the end portion 43 and the end portion 47 are pushed apart, the first arm portion 17 and the second arm portion 18 are elastically deformed with the hinge 16 as a fulcrum, the end portion 42 enters inside the end portion 46, and the engaging portion 44 and the engaging portion 48 are engaged with each other.

[0036] In this way, the tubular body 11 is held by the first arm portion 17 and the second arm portion 18 in the space G1. When removing the tubular body 11 from the insert clip 10, the operator pulls the first arm portion 17 to release the engaging portion 44 and the engaging portion 48. Therefore, the tubular body 11 can be removed from the fixed object 12.

[0037] The tubular body 11 held by the insert clip 10 is arranged along the first direction B1. Further, the main body portion 13 extends along the first direction B1. Therefore, as shown in Fig. 3(A), when the insert clip 10 is viewed in plan, it is possible to suppress the expansion of the arrangement space of the main body portion 13 in the second direction B2, which is the width direction (thickness direction) of the tubular body 11. Furthermore, when the insert clip 10 is viewed in plan, the entire arrangement region of the main body portion 13 is included within the arrangement region of the tubular body 11. Therefore, it is possible to further suppress the expansion of the arrangement space of the main body portion 13.

[0038] Figs. 6A, 6B and 7 are other specific examples of the insert clip 10. Through holes 50 and 51 penetrating the plate portion 70 and the convex portion 29 are provided. The through hole 50 is opened to the concave portion 25 and a plurality of them are provided on the same circumference centered on the position D1. The through hole 51 is opened to the concave portion 27 and a plurality of them are provided on the same circumference centered on the position D2. The number of the through holes 50 and 51 is arbitrary. In the insert clip 10 of Figs. 6A, 6B and 7, when a load such as an impact force by a tool (hammer or the like) is applied to the plate portion 70, the presence of the through holes 50 and 51 makes the plate portion 70 easily elastically deformed, and cracking and breakage of the plate portion 70 can be suppressed.
