Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wedge bumper mounting structure for pressing a striker engaged with a latch to remove looseness in a locking device used for locking the back door of an automobile.

A conventional door lock device of this type has a striker insertion groove 1 in a base plate 1, as shown in FIG.
A latch 2 and a pole 3 are pivotally mounted on both sides of a, and further,
A mounting plate 4 is provided from the back side of the base plate 1 so as to cover the latch 2 and the pole 3. This mounting plate 4 is bent and formed so that its center part protrudes toward the back side (the front side in FIG. 1), and the space thus formed is used for the striker 5 that enters along the striker insertion groove 1a. A holding chamber 4a is configured to receive and hold the latch, and a cushion 6 is provided in the holding chamber 4a to reduce the impact when the striker 5 is inserted. A wedge bumper 7 is provided. Incidentally, reference numerals 8 and 9 are springs that bias the latch 2 and pawl 3 to rotate in the meshing direction.

By the way, as shown in detail in Figures 2 and 3 (both figures viewed from the base plate side),
The wedge bumper 7 is attached to the mounting plate 4 by a mounting pin 12 having a protruding collar 10 at one end and a spring 11 fitted around the middle. When attaching this wedge bumper 7, the end of the mounting pin 12 on the side opposite to the flange 10 is connected to a spring loose fitting hole 13 with a larger diameter than the flange 10 provided in the wedge bumper 7, and to the back of the loose fitting hole 13. After passing through the fitting hole 14 drilled in the part and fitting into one of the mounting holes 15 of the mounting plate 4, the end of the collar 10 is fitted into the other mounting hole 16 of the mounting plate 4 facing the other side. It is going by. Therefore, the end of the mounting pin 12 on the side opposite to the rib 10 passes through the wedge bumper 7 and into the mounting hole 1 of the mounting plate 4.
5, it is necessary to press the collar 10 of the mounting pin 12 so that the mounting pin 12 does not come out of the wedge bumper 7 due to the force of the spring 11, which makes the mounting work very troublesome. It was hot.

In view of these circumstances, the present invention simplifies the work of attaching the wedge bumper to the mounting plate by fitting the collar of the mounting pin to the wedge bumper tightly to the extent that the mounting pin is not pushed back by the spring force. This invention relates to a wedge bumper mounting structure in a door lock device.

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 4, one end of a mounting pin 12 for inserting a spring 11 into the wedge bumper 7 with the spring 11 externally fitted into the middle portion can be tightly fitted into the loose fitting hole 13 of the wedge bumper 7. The wedge bumper 7 has a tapered portion 13a for guiding the collar 10 of the mounting pin 12 to the entrance edge of the loose fit hole 13. At the same time, a groove 17 for adjusting the fitting force between the loose fitting hole 13 and the collar is formed on the outside of the tapered portion 13a in a circular arc shape, a facing circular arc shape, and a circular arc shape as shown in FIGS. 6A, B, and C. Carve at the required depth in the desired shape. In FIG. 4, the same reference numerals as in FIGS. 2 and 3 indicate the same parts.

When attaching the wedge bumper 7 to the mounting plate 4, as shown in FIG.
Wedge bumper 7 is placed at the required location on the surface facing the
A protrusion 18 is provided to prevent the flange 10 from fitting into the loose fitting hole 13 when the flange 10 moves toward the flange 10 of the mounting pin 12 against the force of the spring 11.

In such a state, first, the end of the mounting pin 12 on the side opposite to the collar 10 with the spring 11 fitted thereon is inserted into the loose fitting hole 13 of the wedge bumper 7, and then passed through the fitting hole 14 and removed from the fitting hole 14. protrude to At this time, since the outer diameter of the collar 10 of the mounting pin 12 is larger than the outer diameter of the loose fit hole 13 of the wedge bumper 7, the collar 10 is guided by the tapered portion 13a and enters the loose fit hole 13. , fit tightly. Incidentally, when the collar 10 pushes out the loose fitting hole 13 and fits into the loose fitting hole 13, the fitting force is adjusted so as not to be too tight by the adjusting groove 17 on the outside of the tapered portion 13a.

Next, with the wedge bumper 7 fixed, the end of the mounting pin 12 protruding from the wedge bumper 7 on the side opposite to the collar 10 is inserted into one of the mounting holes 15 of the mounting plate 4, and the collar of the mounting pin 12 is inserted. The end portion on the 10 side faces the other mounting hole 16 of the mounting plate 4. After that, by releasing the fitting between the collar 10 and the loose fitting hole 13, the collar 10 of the mounting pin 12 is removed.
The side end portion is inserted into the mounting hole 16 to achieve the mounted state.

Wedge bumper 7 is installed using the above work procedure.
By attaching it to the mounting plate 4, there is no need to press the collar 10 of the mounting pin 12, and the work can be carried out smoothly.

In the above embodiment, the tapered part 13a was provided at the entrance edge of the loose fitting hole 13 of the wedge bumper 7, and the fitting force adjustment groove 17 was provided on the outside of the tapered part 13a, but these are not necessarily required. do not have.

As explained above, according to the wedge bumper mounting structure of the present invention, there is no need to press the collar of the mounting pin against the spring when inserting the mounting pin into the mounting hole of the body. Installation workability is improved.
