Description

[Detailed description of the invention] "Industrial application field" The invention is applicable to, for example, a fuse in a joint box provided in the middle of an automobile wiring harness,
This relates to a puller, which is a pulling tool used to pull out lighting bulbs (tubular lighting lamps), etc.

``Prior art'' and ``Problems to be solved by the invention'' In general, it is difficult to pull out the fuses and light bulbs in the joint box with your fingertips, so a unique hold that corresponds to the shape of the fuse or light bulb is required. A dedicated tool with a separate section is provided.

Therefore, in joint boxes that are strongly required to be smaller and more compact, the number of attached tools increases, which is an undesirable problem.

The purpose of the present invention is to solve the above-mentioned conventional difficulties, and to provide a compact multifunctional puller that can be used for two types of members with different shapes using a single tool.

``Means for Solving the Problems'' The puller of the present invention that achieves the above object is provided with a pair of clamping parts at both ends consisting of clamping pieces on two opposite sides passing through clamping holes between the opposing sides, The axes of the clamping holes of the pair of clamping parts are perpendicular to each other, and each of the clamping pieces on the two opposing sides is bent on the opposing surface using the clamping piece of the clamping part on the other side as a base. This is a free end portion of a pair of cantilever-like elastic pieces having a space, and the cantilever-like elastic pieces are composed of four elastic beams partitioned by the cross-shaped bending space,
Furthermore, the clamping piece is formed into a clamping locking piece or a holding piece corresponding to the shape of the pull-out member, and has a structure in which the pull-out member is clamped and pulled out by the clamping part.
It's getting old.

"Example" and "Operation" Hereinafter, a detailed explanation will be given based on an example. Referring to FIGS. 1 and 2, which show one embodiment of the invention, the figures show a puller that serves both as a fuse and a lighting bulb in the fuse box, and A in FIG. 1 is a front view thereof, and B is a C is its right side view, C is its left side view, D is its top view, and FIG. 2A is a perspective view of the first illustrated puller.

In the figure, the puller of the present invention is provided with two clamping parts 7 and 8 at both ends, which pass through a clamping hole 6 between opposing clamping pieces 5 on two opposing sides and are slightly opened at the front. The axes 9A and 9B of the clamping holes 6 of the attachment parts 7 and 8 are orthogonal to each other. The clamping pieces 5 on the two opposing sides of the clamping part 7 at one end extend with the clamping pieces 5 of the clamping part 8 on the other side as a base, as shown in FIG. 1A. A pair of cantilever-like elastic pieces 1A having
1B, and the clamping part 8 at the other end.
The clamping pieces 5 on two opposing sides are a pair of cantilever-like elastic members that extend from the clamping piece 5 of the clamping part 7 at one end as a base and have a bending space 11 on the opposing surface, as shown in FIG. 1D. Piece 2
It becomes the free end part of A2B.

That is, the clamping parts 7 and 8 at both ends perpendicular to the axes 9A and 9B are cantilever-like elastic pieces whose fixed ends are the proximal ends of the clamping pieces 5 of the clamping parts 7 and 8 on the other side, respectively. (hereinafter simply referred to as elastic piece) 1A1B or 2A
2B, the free end portion of the cantilever becomes a clamping piece 5, and the opposing clamping pieces 5 can elastically flex toward each other and move toward and away from each other.

The elastic beam group that connects the clamping parts 7 and 8 at both ends to form the elastic pieces 1A1B and 2A2B is connected to the second elastic beam group.
See Figures A, B, and C, flexible space 1 communicating in a cross shape.
It is composed of four elastic beams 10A to 10D divided by 1, of which 10A and 10B are connected to the elastic piece 1A whose free end is one clamping piece 5 of the clamping part 7, and 10C and 10D is an elastic piece 1B which makes the other clamping piece 5 of the clamping part 7 a free end, and similarly 10A and 10C are elastic pieces 2A which make one clamping piece 5 of the clamping part 8 a free end. Similarly 10B and 10
D becomes the elastic piece 2B which makes the other clamping piece 5 of the clamping part 8 a free end, and the elastic beams 10A to 10D become the elastic piece 1.
It is configured to function as an elastic beam common to both A1B and 2A2B.

Then, when the point of action 13 on the outer side between the elastic pieces 1A1B and 2A2B is pinched and pressed with fingertips, the elastic piece 1A
1B and 2A2B are elastically bent and brought close to each other, so that the clamping piece 5 at the free end part clamps the member or article to be pulled out. Note that 14 in the figure is a non-slip protrusion.

The clamping piece 5 at the free end portion of the elastic piece 2A2B is provided with a locking claw 15 corresponding to the shape of the head of the fuse in the opposing direction, and the clamping part 8 for the fuse is
The clamping piece 5 at the free end portion of the elastic piece 1A1B has an arcuate portion 12 corresponding to the shape of the lighting bulb in the opposite direction.
The clamping part 7 of the lighting bulb becomes a clamping piece having
is formed.

Then, as shown in FIG. 3, the locking claw 15 of the clamping piece 5 of the clamping piece 8 is clamped to the flange part 17 of the fuse 16, or the arcuate part 12 of the clamping part 7 is connected to the lighting bulb (not shown). The fuse or lighting bulb can be pulled out from the fuse box by holding the fuse or light bulb around the outer periphery of the fuse box (not shown) and pulling it while holding each point of action 13 with your fingertips or the like.

The puller of the present invention having the above configuration has a clamping part 7 having clamping pieces 5 on two opposing sides formed by the free ends of the elastic pieces.
and 8 are provided at both ends, and the clamping parts 7 and 8 are connected by four elastic beams 10A to 10D, so the shape is compact.
By making the clamping pieces 5 of 8 correspond to the specific shapes of the members and articles to be pulled out, it is possible to pull out many types of members and articles using a single, compact tool.

Then, four elastic pieces 1 consisting of four elastic beams 10A to 10D separated by a cross-shaped bending space 11 are provided.
Since the clamping parts 7 and 8 that share A to 2B are provided at both ends, the common elastic pieces 1A to 2B always act elastically even when the clamping parts 7 and 8 act as clamps. In addition, when the clamping part 7 performs a clamping action, the clamping part 8 on the opposite side acts as a proximal end of the clamping part 7, and when the clamping part 8 performs a clamping action, the clamping part 8 on the opposite side There is a mutual supporting function in which the attachment part 7 acts as a base end part of the clamping part 8. Therefore, the dedicated elastic pieces of the clamping parts 7 and 8 are unnecessary, and the shape is reduced.

``Effects of the invention'' As explained above, the puller of the invention is a convenient tool with multifunctionality for pulling out multiple parts, as well as four elastic pieces that form clamping parts for pulling out parts provided at both ends. However, since it has a special structure that allows the clamping parts at both ends to have a common function and a mutually supporting function, for example, the clamping parts at both ends may be provided with exclusive elastic pieces in opposite directions via the central base end, or Compared to a common elastic piece with clamping parts at the middle and tip, the total length of the tool to achieve the same clamping action is approximately half, making it extremely compact and practical for easy handling and storage. It is effective in providing a multi-functional tool.
