JPS60987Y2 - Locking device for opening/closing body in automobiles - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device for an opening/closing body in an automobile, and relates to a locking device most suitable for a remote control device for a fuel filler lid lock.

Conventionally, in a locking device for a fuel filler lid (hereinafter simply referred to as a lid), which is an opening/closing body, a lock case 2 is fixed to a fuel vessel portion 1a of a vehicle body fender 1 via a clip 3, as shown in FIG. The lid 5 is opened and closed by a locking piece 4 housed in the case 2 engaging and disengaging from a keeper 6 protruding from the lid 5.

Inside the case 2, the locking piece 4 is always urged by the coil spring 8 in the direction of engaging with the keeper 6, and the locking piece 4 and one end 10a of the inner wire 10 of the Bowden cable 9 engage the slider 11. The slider 11 is always urged by a coil spring 12 so as to be in the solid line position in FIG.

The outer tube 13 of the Bowden wire 9 is fixed to the rear end of the case 2 by caulking.

The other end of the Bowden wire 9 is connected to a remote control handle (not shown) inside the vehicle interior.

When the lid 5 is opened, the inner wire 10 is actuated in the direction of arrow P by operating the handle,
Due to the operation of this inner wire 10, the slider 11
The latch piece 4 moves backward in the P direction via the latch piece 4.
The engagement with the keeper 6 is released, and the lid 5 is opened.

On the other hand, when the lid 5 is closed, the keeper 6 comes into contact with the latch piece 4 and retreats the latch piece 4 in the direction P along the slope 4a.
Once the engaging piece 6a of the keeper 6 has passed, it is returned to the original position shown in solid line in FIG. 1 by the biasing force of the coil spring 8, and is engaged with the keeper 6 and locked.

Note that after the lid 5 is opened, the inner wire 10 is returned to the original solid line position by a coil spring 12.

Such a device can lead to a number of problems in one day.43
It is described on page 410 of the Type 0 Maintenance Manual (published in July 1978).

However, such a locking device has separate coil springs 12 for returning when the lid is open and coil springs 8 for returning when the lid is closed, and these springs 8 and 12 are not protected from dust etc. In order to prevent the springs 8 and 12 from malfunctioning due to dust, etc., the springs 8 and 12 are housed in the case 2 so as to cover the entire circumference. There is a problem in that if the lid 5 is opened, the lid 5 cannot be opened.

This kind of problem does not occur at all with a locking device in which the keeper 6 of the lid 5 can be unlocked by moving it from outside the vehicle using a cylinder key, but it is a serious problem with a locking device that does not have a cylinder key. The problem was that the lid 5 had to be forcibly deformed using a tool to open it, and the lid 5 had to be kept closed with duct tape or the like after refueling while driving, and the appearance quality was poor as well. .

For this reason, it is necessary to use an expensive material with high strength and durability for the inner wire 10.
It was disadvantageous in terms of cost.

In view of these conventional problems, the present invention is designed to enable manual unlocking directly at the location where the case is located, and to release the spring when remote control of the locking device becomes impossible for some reason, that is, in an emergency. This prevents malfunctions and improves operability.

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings, in which the same parts as those in the prior art are denoted by the same reference numerals.

□ In Figures 2 to 5, the latch piece 4 that engages with and disengages from the keeper 6 of the lid 5, and this latch piece 4
The operating end 10. of the Bowden cable 9 has one end of the inner wire 10 operatively connected to a file spring 20 and a handle (not shown) in the passenger compartment. a, and a slider 11 that connects the operating end 10a of the inner wire 10 and the locking piece 4 are housed in the case 2.

This case 2 has a mounting seat part 21 protruding from its front end, and when attached to the fuel vessel part 1a of the vehicle body, the case 2 cooperates with the seat part 21 to attach the mounting seat part 21 to the vehicle body fuel vessel part 1a.
A clip lip 22 is provided to hold the clip.

Further, as is clear from the figure, the case 2 is divided into a front chamber 2a and a rear chamber 2b with a partition 2c, and the locking piece 4 and the spring 20 are housed in the front chamber 2a so that the entire circumference is covered.
The connecting portion between the rear end portion 4b of the hooking piece 4 and the slider 11 and the connecting portion between the slider 11 and the inner wire 10 are located in the rear chamber 2.
A window 24 is formed in the upper wall facing the rear chamber 2b.

If the inner wire 10 were to break for some reason, the window 24 would not be able to be unlocked even if the operating handle inside the vehicle was operated, so the slider 11 would have to be manually moved (i.e. by the passenger's or worker's finger 26) as shown in FIG. In other words, the window 24 is an emergency manual unlocking window.

A slit 2f is formed in the rear end wall 2e of the case 2, and the outer tube 13 of the Bowden cable 9 is locked therein.

In addition, numeral 28 in the figure is a stopper that prevents the slider 11 from being removed from the hooking piece 4.

With this configuration, when the lid is normally opened, the inner wire 10 can be opened by operating the operating handle inside the vehicle.
operates in the direction of arrow P in Fig. 2, and in conjunction with this, the slider 11 and the latch piece 4 also move in the direction P, reaching the position shown in Fig. 3, where the keeper 6 and latch piece 4 are separated, and the lid is removed. 5 opens.

When opening the lid, it is only necessary to pull the inner wirer with a force that resists the biasing force of the spring 20, so the operating force is light and the operability is good.

Also, when the lid 5 is closed, the latch piece 4 is moved to the P position by the keeper 6.
When the engaging piece 6a of the keeper 6 passes, it will be in the position shown in Fig. 4, and the latch piece 4 will return to the original state shown in Fig. 2 due to the biasing force of the coil spring 20, and the lid 5 will be closed. .

It should be noted that when the lid 5 is closed, the latch piece 4 swings against the slider 11 between the rear end 4b of the latch piece 4 and the slider 11.

Therefore, when the lid is closed, only the latch piece 4 needs to be moved by a force that resists the biasing force of the spring 20, and the lid closing operation force is light, resulting in good operability.

Furthermore, in the case of an emergency in which the inner wire 10 is cut for some reason or the operation handle inside the vehicle malfunctions, for example, the trunk lid (not shown) can be opened,
Put your finger 26 into the window 24 facing into the trunk room, manually force the slider 11 to move in the P direction,
Move the latch piece 4 in the P direction to release the lock.

As is clear from the above explanation, in an emergency when the inner wire of the Bowden cable is cut for some reason or the remote control handle malfunctions, the lid can be unlocked manually through the window cut into the case. The problem of not opening will be resolved.

Then, divide case 2 into two chambers and use spring 20.
Since the front chamber in which the is housed is reliably protected from dust and the like, there is no need to worry about the spring 20 malfunctioning, and the number of waist spring means can be reduced by one compared to the conventional one.

Moreover, the outer tube 13 of the Bowden cable 9 is simply locked to the rear wall of the case 2, so there is no need to swage it as in the conventional case.

In addition, the operating force when opening and closing the lid is light, and the operability is extremely good.

Although the above embodiment describes a device that is remotely controlled using a Bowden cable, the same applies to a device that is remotely controlled using an electromagnetic solenoid (that is, a type in which an electrode solenoid is connected to the operating end of the inner cable). It can also be applied to back doors and trunk lids in addition to fuel filler lids as opening/closing bodies.
