[Industrial applications]

 The present invention relates to improvement of a clamp for supporting a wire, a rod-shaped object such as a pipe, an electric cord, an electric wire cable or a wire for various operations, and more specifically, a nut incorporated in a groove provided in a substrate. The present invention relates to the provision of a clamp that is constantly restricted to a predetermined position by arcuate nut holding pieces that are provided facing each other in the groove.

[0002]

[Prior art]

 To fix pipes, electric cords, etc. installed in vehicles such as passenger cars to the vehicle panel for wiring and piping, attach a clamp to the stud bolt that has been conventionally installed upright on the vehicle panel. A technique for holding pipes, cords, etc. by the holding groove provided is used. To attach the clamp to the stud bolt, insert the stud bolt into the insertion hole of the stud bolt provided in the clamp, and then insert the nut from the tip of the stud bolt to secure the clamp between the bolt base and the nut. It is done by tightening. However, the attachment of the clamp to the stud bolt is often performed by hand due to its nature, and an error may occur in the standing position of the stud bolt.Therefore, among the parts of the vehicle that require wiring and piping, etc. However, it was difficult to insert the stud bolts, which are difficult to reach, and particularly the stud bolts standing on the bottom panel of the vehicle, into the insertion holes of the stud bolts provided in the clamp accurately and quickly. For this reason, conventionally, in this type of clamp, the stud bolt insertion portion is not formed into a hole shape, but the stud is provided as the slit 101 provided in the thickness direction of the clamp 100 as in the clamp 100 shown in FIG. The bolt is easily received in the clamp 100. In the clamp shown in FIG. 13, the stud bolt received in the groove 103 communicating with the slit 101 from the slit 101 is temporarily fixed by the locking claw piece 102 provided on the edge of the slit 101. After that, the nut held by the nut holding piece 104 provided on the upper edge of the groove 103 is fitted into the stud bolt with a jig such as an impact wrench, and the clamp is assembled to the stud bolt.

[0003]

[Problems to be solved by the device]

 However, when the insertion portion of the stud bolt is the slit 101, the stud bolt can be easily received in the clamp 100, but the stud bolt thus received is at the center position of the slit 101, in other words, the width dimension of the clamp 100 is about the middle. There is a situation in which the clamp 100 is not arranged at a position but is unevenly arranged on one of the side edges in the longitudinal direction of the clamp 100. In this case, when the clamp 100 is fixed to the panel by fitting the nut into the stud bolt, the clamp 100 is fixed to the panel at the planned position, that is, the stud bolt is arranged at the center position of the slit 101 of the clamp 100. In this case, the clamp 100 is mounted on the panel in a state in which the stud bolt is displaced from the position where the clamp 100 is supposed to be arranged. As a result, the arrangement of other members, cords, wires, pipes, etc., which form the vehicle, where the arrangement positions of the clamps 100 are determined respectively, are determined by the clamp 100 being biased. There were some inconveniences, such as being unable to do it or making it difficult to do it because of being disturbed by 100. Also, when the cord, pipe, wire, etc. held by the clamp 100 is pulled for some reason, and the stud bolt is not arranged at the center position of the slit 101, the clamp 100 uses the stud bolt 101 as a fulcrum. There was an inconvenience that the position of the clamp 100 was further displaced due to being swung. Further, no means has been taken to correct such a displacement of the clamp 100 afterwards.

Therefore, the present invention eliminates the inconveniences that such conventional clamps have, and the predetermined position of the slit is fixed regardless of the receiving position of the stud bolt to the slit provided in the clamp. By providing a clamp with a structure in which the position of the clamp itself can be adjusted with respect to the stud bolt so that the stud bolt is always placed on the panel, this type of clamp can be easily and properly assembled to the panel. The purpose is to permanently secure.

[0005]

[Means for Solving the Problems]

 In the present invention, in order to solve the inconvenience of the above-mentioned conventional clamp, a clamp for a wire or rod-like object is provided with a slit 14 formed in the thickness direction for receiving a stud bolt C standing upright on a panel or the like, and a wire or rod-like clamp. A clamp board 10 having means for attaching an object, and a nut B incorporated in the clamp board 10. The clamp board 10 is provided with a groove 11 continuously over the entire width of the slit 14 and the groove 11. A nut holding piece 15 curved in an arc shape is provided on the upper end edges of 11 facing each other in an arcuate concave portion 15a in a protruding shape, and the nut B is housed in the groove 11 and a flange portion is formed. 21 is attached to the clamp substrate 10 in a state of being in contact with the clamp substrate surface 10.

[0006]

【Example】

 Hereinafter, a typical embodiment according to the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view of a clamp according to this embodiment, FIG. 2 is a plan view thereof, FIG. 3 is a bottom view thereof, FIGS. 4 and 5 are side views thereof, and FIG. 6 shows a clamp according to this embodiment. 7 is a plan view, FIG. 8 is a bottom view, FIG. 9 is a cutaway side view of the same portion, FIG. 10 is a sectional view taken along line XX in FIG. 6, and FIGS. It is a side view which shows the use condition of the clamp which concerns on an Example.

The clamp according to this embodiment includes a clamp body A and a nut B. The clamp body A and the nut B do not need to pay particular attention to rust prevention, the manufacturing cost is relatively low, and the elastic deformation characteristics are provided to improve the usability of the clamp. It is preferable to form it by injection molding using a plastic resin as a material.

The clamp body A is configured with a substantially rectangular clamp substrate 10 as a base, which has a groove 11 extending in the width direction at a substantially central portion thereof and opening to the side of the clamp body A. The groove 11 has a depth in which the nut B can be accommodated, and the groove bottom is a groove bottom plate portion 13 having a flat surface substantially parallel to the flat surface 12 of the clamp base plate 10. The slit 14 is provided so as to extend across the width of the clamp substrate 10. A plurality of stud bolt locking claws 14a facing each other extend from the edge of the slit 14, and the distance between the tip ends of the stud bolt locking claws 14a facing each other is the diameter of the stud bolt C received in the slit 14. It is said to be narrower than that. Therefore, the stud bolt locking claw 14a has a function of locking to the outer peripheral surface of the received stud bolt C to enable temporary fixing of the clamp body A to the stud bolt C. The fitting work to C is facilitated. Both side edges of the groove bottom plate portion 13 have extended portions on both sides of the clamp body A on the longitudinal side.

From the upper end edges of the groove 11 facing each other, a pair of nut holding pieces 15 curved in an arc shape are provided in a protruding shape with the arc-shaped concave portions 15 a facing each other, with the slit 14 interposed therebetween. .

On the other hand, on the surface of the clamp substrate A opposite to the flat surface 12, a clamp portion 16 as a wire or rod-shaped attachment means communicating with the width direction of the clamp substrate A is sandwiched between the grooves 11. So I own two on one side and three on the other. Each clamp portion 16 is surrounded by a clamp substrate 10 and a side wall 16a standing upright from the clamp substrate 10 toward the groove bottom side of the groove 11, and is open at one end and has a wire or rod-shaped insertion port. It is said that. A claw piece 16b facing the bottom side of the clamp part 16 and extending in the width direction of the clamp substrate 10 is provided at a substantially tip end of the side wall 16a near the insertion port. It should be noted that the clamp portion 16 may be configured to communicate in the longitudinal direction of the clamp substrate A. In addition, on the flat surface 12 of the clamp board A, locking hook portions 17 having a hook-shaped cross section that are bent toward the outer side in the width direction of the clamp board A are provided at substantially symmetrical positions with the groove 11 interposed therebetween. It is erected. A metal bracket D, which will be described later, is locked to the locking hook portion 17.

Next, the nut B has a tubular base portion 20, a flange portion 21 provided on one edge of the tubular base portion 20 in the axial direction, and a hexagonal columnar shape provided on the surface of the flange portion 21. And the wrench tightening part 22. A rib 23 having an inclined surface inclined inward toward the outside is provided around the edge of the tubular base portion 20 on the side of the tubular base portion 20 where the collar portion 21 is not provided. A stepped surface 23 a is formed between the tubular base portion 20 and the rib 23 by 23.

As shown in FIG. 9, the inner surface of the opening portion of the nut B on the side where the ribs 23 are provided is inclined toward the inside of the cylindrical base portion 20 from the vicinity of the opening edge in a tapered shape. The inclination of the inclined surface portion 24 ends at a position where the inner diameter of the inclined surface portion 24 is substantially equal to the outer diameter of the stud bolt C inserted into the nut B. A stud bolt tightening hole 25 communicating with the end surface of the wrench tightening portion 22 of the nut B and communicating with the outer diameter of the stud bolt C is provided.

The inner peripheral surface of the stud bolt tightening hole 25 is provided with four grooves 25 a in the axial direction of the tubular base portion 20. This groove 25a is formed when the male screw of the stud bolt C inserted into the stud bolt tightening hole 25 is screwed to the nut B while forming a female screw portion on the inner peripheral surface of the stud bolt tightening hole 25. It serves to escape the meat on the inner peripheral surface of the tightening hole 25 to facilitate the screwing operation. Further, on the outer peripheral surface of the tubular base portion 20 of the nut C, a hole 26 facing the stud bolt tightening hole 25 is provided for the purpose of reducing the weight of the nut C and the like.

Next, a method of using the clamp according to this embodiment will be described with reference to FIGS. 11 and 12.

In FIG. 11, a metal bracket D is elastically attached to the flat surface 12 of the clamp body A of the clamp by the locking hook portion 17. The flat surface 12 has a metal bracket. Covered by D. Further, the nut B is assembled to the clamp body A in a state where the tubular base portion 20 is housed in the groove 11 of the clamp substrate 10. The stud bolt C is received in the groove 11 of the clamp body A through the slit 14 of the clamp body A of this clamp. A stud bolt locking claw 14a provided at the edge of the slit 14 is locked near the bolt base of the received stud bolt C, whereby the clamp is temporarily fixed to the stud bolt C. The clamp temporarily fixed to the stud bolt C in this manner is finally fixed to the stud bolt C by fitting the nut B into the stud bolt C. In this final stop, as described above, the nut B is held by the nut holding piece 15 of the clamp main body 10 by abutting the step surface 23a of the rib 23, so that it is necessary to separately prepare the nut B. It is not necessary to perform clamp placement work smoothly. In this embodiment, the nut B is held by the arc-shaped nut holding pieces 15 provided on the upper end edges of the groove 11 facing each other, and the gap between the nut holding pieces 15 and 15 is the clamp body. Since the width of the nut B is narrower toward the side of A, the nut B sandwiched between the holding pieces 15 does not fall out of the groove 11 toward the side of the clamp body A.

As described above, the inner surface of the opening of the nut B on the side where the rib 23 is provided is the inclined surface portion 24 that is inclined toward the inside of the tubular base 20 from the vicinity of the opening edge in a constricted shape. Since it is communicated with the stud bolt tightening hole 25, it is easy to fit the nut B to the stud bolt C received in the clamp body A, and after the fitting, the male screw portion of the stud bolt C is fitted to the stud bolt C. It is easy to lead to the tightening hole 25. Particularly, even when the stud bolt C is received in the slit 14 in a state of being biased to the side of the clamp body A, the stud bolt C is guided to the stud bolt tightening hole 25 by utilizing the inclined surface portion 24. It is possible.

After the stud bolt C is guided to the stud bolt tightening hole 25 in this way, a jig such as an impact wrench is fitted to the wrench tightening portion 22 of the nut B and the nut B is rotated. In the stud bolt tightening hole 25, while the male screw of the stud bolt C is made to bite into the inner wall of the stud bolt tightening hole 25 to form a female screw on the inner wall surface, the tip edge of the stud bolt C is the wrench of the nut B. Push it to the end face of the tightening portion 22 and screw it. By this screwing, the clamp body A is sandwiched between the panel surface P of the base edge of the stud bolt C and the flange portion 21 of the nut B, and is fixed to the panel as shown in FIG.

[Effect of device]

 In the wire and rod-shaped object clamp according to the present invention, the nut held by the clamp is regulated by the arc-shaped recess of the nut holding piece of the clamp, that is, the arc-shaped recess of the nut holding piece formed facing each other is formed. The nut can be maintained at the center position of the arc by abutting the arc-shaped edge on the circumferential surface of the nut, so that the nut can be constantly maintained at the predetermined position on the slit. . Thus, according to the clamp of the present invention, the stud bolt is biasedly received on either side of the width direction of the clamp in the slit of the clamp for receiving the stud bolt, or is retained after the clamp is assembled to the stud bolt. Even if the assembly position of the clamp with respect to the stud bolt changes due to external factors such as pulling of wire or rod-shaped object, etc., it will be fitted into the stud bolt and the above-mentioned slit by the nut holding piece. The nut held at the predetermined position of the clamp is returned to the center position of the arc formed by the nut holding piece of the clamp, by utilizing the action of restricting the position of the nut of the nut holding piece. The position relative to the stud bolt can be changed relative to the nut fixed to the stud bolt. Can, therefore permanent maintenance of the assembly position of the clamp relative to the stud bolt are possible, also, it is possible to ensure the appropriate arrangement of other members constituting the vehicle other than the clamp. Also, since the nut sandwiched between the nut holding pieces does not fall out of the groove toward the side of the clamp, the nut does not fall off to the side of the groove provided in the clamp for holding the nut. It has the feature that there is no need to install a separate wall for this purpose.
