Description

[Detailed Description of the Invention] This invention relates to an improvement of a locking device for a sliding window of a vehicle.

Conventionally, as shown in FIG. 1, a flange portion 3 of a base 2 is fixed to a sliding window 1 of a vehicle, and a hook 5, which is biased in the locking direction by a spring 4, is hinged to the base 2 by a hinge pin 6. Then, remove the hook body 9 of the hook 5 from the lock hole 11 of the lock plate 10 by pinching the fixed knob 8 of the base 2 and the movable knob 7 of the hook 5 with your fingers in a direction toward each other. A locking device that allows the window 1 to be slid has been put into practical use (for example, see Japanese Utility Model Application No. 10770/1983).

However, since a spring 4 and a hinge pin 6 are separately required in addition to the base 2 and the hook 5, the number of parts increases (total of 4 parts) and the number of assembly steps increases, resulting in an increase in cost.

This idea was made to solve the above-mentioned conventional problems. Basically, the hinge pin part is attached to one of the synthetic resin base and the hook, and the spring piece part is attached to the other. It is designed to reduce the number of parts (total of 2 parts) and assembly man-hours, making it possible to manufacture it at low cost.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 2 and 3, the base 15 made of synthetic resin includes a flange portion 17 having base mounting holes 16, 16, and a fixed knob portion 18 standing upright from the flange portion 17. Base mounting holes 16, 16
The protrusions 19, 19 of the flange portion 17 protruding from the sliding window 20 are fitted into the mounting holes 21, 21 from one side, and the backing plate 23 has blind female screws 22, 22 on the other side of the window 20. and insert the screws 24, 24 inserted from the base mounting holes 16, 16 into the blind female screws 22, 24 of the backing plate 23,
By screwing into the window 22, the base 15 is fastened and fixed to the window 20.

The flange portion 17 of the base 15 has a notched hollow bearing portion which is located in front of the fixed knob portion 18 and which holds the hinge pin portion described below so that it cannot be removed when the hinge pin portion is fitted from above in the radial direction. 25 is integrally formed.

On the other hand, the synthetic resin hook 26 includes a hook main body part 28 having a downward hook claw 27, and a movable knob part 2 that extends upright from the hook main body part 28.
9, and spring pieces 30, 30 are integrally formed that protrude from both sides of the rear surface of the movable knob part 29 to fit on both sides of the bearing part 25. The spring piece 30 has a thin upper part, and when it is stopped by the stopper part 14 of the fixed knob part 18 of the base 15, it uses the elastic force of the synthetic resin to move the entire hook 26 in the locking direction. It has a spring action that biases it.

A hinge pin portion 31 that fits into the hollow portion of the bearing portion 25 from the radial direction is integrally formed between the spring portions 30, 30.

If the locking device is configured as described above, the hooks 2 will be installed on both sides of the bearing portion 25 of the base 15 during the assembly process.
While fitting the spring pieces 30, 30 of No. 6, the hinge pin portion 31 is fitted by applying force from above in the radial direction of the hollow portion of the bearing portion 25.

Then, the hook 26 is pivotally attached to the base 15 in a non-removable manner and swingable in the locking direction, and the spring pieces 30, 30 are attached to the fixed knob 15.
8, the hinge pin portion 3
1 from the bearing part 25. In addition, the entire hook 26 is biased in the locking direction.

After that, the protrusions 19, 19 of the base 15 are fitted into the mounting holes 21, 21 of the window 20, and the back plate 23
The base 15 is fastened and fixed to the window 20 with the screws 24, 24.

When you hook your finger on the fixed knob 18 of the base 15 of the window 20 in the open position and slide it in the closing direction, the hook body 28 rides on the front edge of the lock plate 32 in the closed position. The entire hook 26 is swung against the force, and then the hook body 28 falls into the lock hole 33, and the entire hook 26 is swung by the force to lock the window 20 in the closed position.

When the fixed knob part 18 and the movable knob part 29 are pinched with fingers in a direction toward each other, the entire hook 26 is swung against the force, and the hook main body part 28 is removed from the lock hole 33, and in this state, Open the window 20 by sliding it in the opening direction.

In the above embodiment, the bearing part 25 and the stopper part 14 of the spring piece part 30 are formed on the base 15, and the hinge pin part 31 and the spring piece part 3 are formed on the hook 26.
0, however, the hinge pin portion 31 and the spring piece portion 30 may be formed on the base 15, and the bearing portion 25 and the stopper portion 14 of the spring piece portion 30 may be formed on the hook 26.

As is clear from the above explanation, in this invention, the hinge pin part and spring piece part are integrally formed on the synthetic resin base and hook. There is no need to provide one, the number of parts is reduced to two, and the number of assembly steps is also reduced, making it possible to manufacture at low cost.

In addition, since the base is provided with a stopper part that locks the spring piece of the hook, the hinge pin part will not come off from the bearing part (the hook will come off from the base).
can be effectively prevented.
