DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bell crank protector incorporated in a lock mechanism of an automobile door to prevent a door from being unlocked by a wire inserted through a gap between windows. .

[0002]

2. Description of the Related Art A bell crank for driving a door lock mechanism by a door unlocking knob is attached to a body steel plate of an automobile door. Conventionally, a resin clip has been inserted into a mounting hole formed in a body steel plate, and a bell crank has been pivotally attached to this clip with a pin. However, in the past, even without a key, it was possible to insert a wire through the gap in the window and hook and rotate the bell crank to release the door lock.
Further, the conventional clip is difficult to bend, and may be broken due to a large insertion load, and the clip may be forcibly removed, so that the door lock mechanism may be broken.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems and to provide a bell crank protector in which a wire cannot be inserted through a gap in a window to release a door lock. It is the main purpose. Another object of the present invention is to provide a bell crank protector that can be easily attached to a body steel plate and that is difficult to be removed.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a resin flat plate having an annular elastic claw inserted into a mounting hole formed in a body steel plate. A door crank bell crank is rotatably pivoted by a clip driven into the elastic claw from the front side of the flat plate, and a flange for protecting the bell crank is formed below the flat plate. It is. The elastic claw preferably has a tapered projection at a symmetrical position and a plurality of slits around the periphery. Also,
It is preferable that the lower part of the flat plate is extended below the back surface through the thin portion, and an elastic holding portion at the end of the body steel plate is provided.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a fan-shaped resin flat plate constituting the main body of the bell crank protector, and reference numeral 2 denotes an annular elastic claw projecting from the back surface thereof. As shown in FIG. 2, this elastic claw 2 has a plurality of slits 3 formed around a cylindrical body made of resin, and tapered projections 4, 4 are provided at symmetrical positions between the slits 3, 3. . In addition, a gap corresponding to the thickness of the body steel plate is formed between the large-diameter bases of the projections 4 and 4 and the back surface of the flat plate 1.

This bell crank protector is mounted by inserting the elastic claw 2 into a mounting hole 6 formed in the body steel plate 5 as shown in FIG. The bases of the projections 4, 4 are easily bent and spread outward by the elasticity of the body 4 at the same time as the bases of the projections 4, 4 pass through.

Reference numeral 7 denotes a clip which is driven into the center of the elastic claw 2 from the surface of the flat plate 1. The clip 7 has a circular head 8 and a shaft 9, and a bell crank 10 for door lock is rotatably pivoted between the flat plate 1 and the head 8 as shown in FIGS. You can wear it. The shaft 9 of the clip 7 has a tapered tip 11 as shown in FIG. For this reason, by inserting the clip 7 into the center of the elastic claw 2 after inserting the elastic claw 2 into the mounting hole 6 of the body steel plate 5, the elastic claw 2 can be pushed outward to prevent the falling from the body steel plate 5. it can.

As shown in FIG. 1, the bell crank protector of the present invention has a flange 12 at the lower portion of the fan-shaped flat plate 1 so that the bell crank 10 does not hinder rotation. As shown in FIG. 6, when the wire 13 is inserted through the gap of the window and is hooked on the bell crank 10 to rotate, as shown in FIG. It is for protecting.

As shown in FIGS. 1 and 7, the lower portion of the flat plate 1 extends downwardly on the back surface through an elastic thin portion 14.
Elastic holding part 15 for elastically holding the end of body steel plate 5
And the elastic holding portion 15 is held at the end of the body steel plate 5 by the thin portion 14,
The elastic claws 2 can be easily inserted into the mounting holes 6 of the body steel plate 5. The elastic holding portion 15 includes a bent tongue piece 16 to securely hold the end of the body steel plate 5 to prevent the bell crank protector from rattling or generating abnormal noise. An unlocking knob of the door is connected to one end of the bell crank 10, and a door lock is connected to the other end.

[0010]

As described above, the bell crank protector of the present invention is attached to the body steel plate 5 by using the elastic claw 2, and since the elastic claw 2 is easily bent, there is no possibility of breaking as in the prior art. The installation workability is good,
It is hard to come off after installation. Since the bell crank protector of the present invention has the flange 12 at the lower portion of the flat plate 1, it becomes impossible to insert the wire 13 through the gap of the window to rotate the bell crank 10, thereby preventing a conventional theft accident. Can be prevented. Further, since parts other than the bell crank 10 and the clip 7 can be integrally formed of resin, weight reduction and cost reduction can be achieved.
Therefore, the present invention is of high practical value as a bell crank protector that solves the conventional problems.
