Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel attachment structure for a wire end latching fitting.

More specifically, the present invention relates to a mounting structure for a wire end latching device that allows the wire end latching device to be easily attached to a driven member such as a lever.

Conventionally, when a driven member (for example, a lever pivoted at one point) is rotated by the pulling action of a wire, a wire with a cable end fitting is attached to the other end of the driven member.
In response to the pulling action of the wire or the return action of the return spring, the cable end fitting comes into sliding contact with the driven member in response to the rotation of the driven member, thereby preventing undue force from being applied to the wire.

However, in this case, if dust adheres to the engagement part between the cable end fitting and the driven member, or if the cable end fitting becomes fixed to the driven member due to freezing of water that has entered, the operation may become impossible. There are problems such as the wire becoming defective, the wire bending, and depending on long-term use, the wire may break or break.

In order to solve this problem, the present applicant first did not engage the cable end fitting directly with the driven member, but instead hooked the cable end fitting to another latching fitting, and made this latching fitting waterproof. Although it has been proposed to attach such a latch to a driven member, no mounting structure has been found for easily attaching such a latch to the driven member.

The present invention was devised to solve these problems, and the wire end latching fitting can be easily attached to the driven member, and the latching fitting has a waterproof structure.

That is, the mounting structure of the wire one end latching fitting of the present invention includes a wire one end latching fitting, a driven member operated by a wire hooked to the latching fitting, and a wire latching fitting attached to the driven member. By adopting a specific structure for the mounting member, the latching fitting can be easily attached to the driven member, and by attaching waterproof caps to the openings at both ends of the latching fitting. , to prevent water from entering the latching fitting.

Next, this will be explained using drawings.

FIG. 1 is a sectional view showing one embodiment of the attachment structure for a wire end latching fitting of the present invention, and FIG. 2 is a sectional view showing another embodiment.

In FIG. 1, 1 is a metal fitting for one end of the wire, 2 is a wire 3 latched to the metal fitting 1, is a driven member operated by the wire, and 4 is a metal fitting for attaching the metal fitting 1 to the driven member 3. It is a mounting member.

The wire end hook 1 has a cylindrical shape with a through hole 11, and the through hole 11 has a sliding portion 12 with which a cable end fitting 21 fixed to the end of the wire 2 engages in sliding contact. It is formed.

The through hole 11 on the cable end fitting 21 side is formed with a size large enough to allow insertion of the cable end fitting 21, and on the wire 2 side, the cable end fitting 2
The wire 2 is formed in such a size or shape that the wire 2 can freely move in response to the sliding contact of the wire 1.

13 and 14 are waterproof caps that respectively seal the openings at both ends of the latching fitting 1, and are made of highly flexible materials such as rubber and plastic.
In this embodiment, it is attached to the openings at both ends by fitting the concave and convex portions.

The waterproof cap 14 has a through hole 14 through which the wire 2 is inserted.
The wire 2 is inserted into the through hole 14a and attached to the latch 1, and is configured to be deformable as the wire 2 moves.

After attaching the waterproof cap 14 to the hook 1, the cap 14 may be heated to be thermally fused to the wire 2, or an adhesive may be used during attachment to bond the wire 2 and the cap 14 together. You may.

This is preferable because the wire 2 and the waterproof cap 14 can be completely sealed.

The driven member 3 is configured, for example, as a lever with one end pivotally supported, and a mounting hole 31 for mounting the wire one end hook 1 is formed in the illustrated end.

The mounting member 4 is formed by integrally forming an upper circumferential wall 41 and a lower circumferential wall 42, and the upper circumferential wall 41 is configured to be attached to the latch fitting 1 by fitting the concave and convex portions and tightly adhere to the periphery thereof.

Regardless of such uneven fitting, the upper peripheral wall 41 is made slightly smaller than the latching fitting 1, and the peripheral wall 41 is made to be smaller than the latching fitting 1.
It may also be attached by inserting it into the holder to bring it into close contact with the holder.

A portion of the lower peripheral wall 42 is cut out and protruded outward to form a protrusion 42a, and the protrusion 42a is configured to be able to bend inward.

Reference numerals 42b denote slits formed in the peripheral wall 42 at appropriate intervals. Providing such slits 42b is preferable because the protrusion 42a becomes easier to bend.

Further, the upper peripheral wall 41 may also be formed with a suitable notch or slit 42b, which has the advantage of making it easier to attach the attachment member 4 to the hooking member 1.

Attach the latch 1 to the driven member 3 using such a mounting member 4 (this is done by attaching the upper peripheral wall 41 of the mounting member 4 to the latch 1 in advance, and then attaching the mounting hole of the driven member 3 to the latch 1. 31, and the lower peripheral wall 42 of the mounting member 4 can be inserted into the mounting hole 31. In this way, the protruding portion 42a is bent inward, so that the lower peripheral wall 42 can be inserted into the mounting hole 31.
When the protruding part 42a comes out of the mounting hole 31, it returns to its original state, and as shown in the figure, the protruding part 42a and the upper peripheral wall 41
The peripheral edge of the attachment hole 31 can be held between the two, and the latch fitting 1 can be attached to the driven member 3 very easily.

Furthermore, the present invention has the excellent advantage that water does not enter into the latch 1 because the waterproof caps 13 and 14 are attached to the openings at both ends of the latch 1, respectively.

Since the embodiment shown in FIG. 2 differs only in the shape of the mounting member, the same reference numerals as in the previous embodiment are used for the same members.

In this embodiment, the protrusion 42a of the mounting member 4 is formed to bulge out into the lower peripheral wall 42, and the protrusion 42a is configured to bend inward from a slit 42b formed in the lower peripheral wall 42.

The operation and effect are exactly the same as those of the embodiment shown in FIG. 1, so the explanation will be omitted.

As described above, the mounting structure of the wire end latching fitting of the present invention allows the wire one end latching fitting to be easily latched to the driven member, and can be installed with one touch, especially in narrow spaces. It is extremely convenient to use because the work is extremely simple, and since the latching fitting is waterproof, water does not get inside the latching fitting, making it a dog of great practical value. be.
