Description

[Detailed description of the invention] This invention provides a door lock for multiple doors in a car.
The present invention relates to a locking/unlocking operation device for door locks that can be locked and unlocked using a single operation device provided near the driver's seat.

In recent years, it has become popular to link the door locks of each door of a car with an operating device installed near the driver's seat using wire cables, etc., so that each door lock can be controlled remotely using this operating device. It is being done.

However, in conventional devices of this type, only one door lock can be locked and unlocked using one operating device, so multiple door locks, such as the left and right door locks at the rear of a car, can be locked and unlocked. In order to remotely control the door locks, a number of operating devices corresponding to the number of door locks must be provided near the driver's seat.

As a result, the device becomes complicated and large, a large space must be secured near the driver's seat for installing a plurality of operating devices, and the operation becomes complicated.

Therefore, a plurality of driven levers that can be engaged and disengaged are arranged on both sides of one operating lever, and the waist operating lever can be moved in a planar H-shape, for example, similar to the switching operation of a shift lever in an automobile transmission. By doing so, it is conceivable to selectively engage or disengage the operating rod and each driven lever, thereby selectively locking/unlocking a plurality of locking devices linked to each driven lever.

However, in such a device that selectively engages and disengages the operating lever, when the operating lever that is engaged with one driven lever is to be engaged with another driven lever, the operating lever is There are restrictions in that the rod must be returned to the neutral position, and all driven levers must also be returned to the neutral position.

As a result, this device has the following drawbacks.

(a) It is impossible to simply link each driven lever and the locking device with a wire, etc., and the locking device can be operated from the driven lever side, but the reverse is not possible. Requires a linking device.

When the hip locking device is locked or unlocked by manual operation, etc.
If the driven lever were to move automatically in conjunction with the driven lever, the operating rod would not be able to engage the driven lever, resulting in malfunction.

(b) Of the reciprocating motion of the operating rod in one direction, only the forward stroke is actually used to lock and unlock the locking device; in the backward stroke, the driven lever is simply returned to the neutral position and the lock is activated. The device cannot be locked or unlocked, and the operation of the operating lever becomes complicated accordingly.

For example, one locking device can be locked by moving the operating rod from the neutral position in one direction, but the locking device can be unlocked by returning the operating rod from that position to the neutral position. It is not possible to lock the lever, which is disadvantageous in terms of economical operation of the operating lever.

(C) It is not possible to confirm the state of each locking device just by looking at the position of the operating lever.

The present invention aims to provide a door lock/unlock operating device that eliminates the above-mentioned drawbacks, and will be described below based on embodiments shown in the accompanying drawings.
