Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an unlocking device that is commonly used in two of the various locking devices installed in automobiles, such as a fuel filler locking device and a trunk locking device.

This type of common unlocking device uses a push-pull wire, and basically unlocks two systems of locking devices depending on the forward or reverse movement direction of the push-pull wire. However, conventional devices have a configuration in which a push-pull wire is directly connected to one locking device, and a locking piece that interlocks with another locking device is fixed at an intermediate position of this push-pull wire, or The structure was such that the integrated interlocking member was linked to two operating levers that were linked to two systems of locking devices.
However, the former method requires an expensive push-pull wire to be extended from the operating position of the driver's seat to, for example, a locking device in the trunk, and the latter method has a problem in that the structure is complicated.

With this invention, the expensive push-pull wire can be used only in the vicinity of one lock device close to the operating position, and the direction of pulling out the operating wire to other lock devices can be set arbitrarily. , provides a common unlocking device with a simple structure and reliable operation.The feature is that an unlocking lever is provided near the first locking device and is pivoted at approximately the center. By connecting a push-pull wire to one end of the lock lever and an operating wire connected to another lock device to the other end, the other lock device can be unlocked by movement of the push-pull wire in one direction. In addition, an unlocking portion that interlocks with the unlocking member of the first locking device is provided at the end of the unlocking lever on the side where the push-pull wire is connected, so that movement of the push-pull wire in the other direction The key point is that this first lock device is used to unlock the door.

The present invention will be explained below with reference to illustrated embodiments. In this embodiment, the common unlocking device of the present invention is applied to the fuel filler lock device O and trunk lock device T, and the operating device 11 provided near the driver's seat and the casing 12 of the fuel filler lock device O The casing 12 is connected to the casing 12 by a push-pull wire 13.
and the trunk lock device T are connected by an operating wire 14 consisting of a pull wire. The trunk lock device T is provided at the end of the trunk lid 15, and the operating wire 14 is connected to the casing 1.
Like the push-pull wire 13, it comes out in the front direction from 2, passes through the hinged portion of the lid 15, and reaches the trunk lock device T.

Inside the casing 12, as shown in FIG.
An unlocking lever 18 pivotally connected to the base plate 16 by a shaft pin 17 is disposed. This unlocking lever 18 has arms 18a, 18 extending upward and downward in the figure from the shaft pin 17.
One end of the push-pull wire 13 is connected to one lower arm 18a, and one end of an operating wire 14 is connected to the other upper arm 18b. Push-pull wire 13 and operation wire 14
is the arm 18 at a substantially equal distance from the shaft pin 17.
a, connected to arm 18b, and both wires 13,1
4, in the vicinity of the unlock lever 18,
They extend in substantially the same direction (forward in the illustrated embodiment). Therefore, when the push-pull wire 13 is pulled in the direction of arrow A by the operating device 11, the operating wire 14 is pulled in the direction of B, which is opposite to A. In other words, the direction of the force applied to the push-pull wire 13 is changed and transmitted to the operating wire 14.
unlocks the trunk lock device T. 1
9 and 20 are rollers and spherical members for connecting the push-pull wire 13 and the operating wire 14 to the arms 18a and 18b; 21 and 22 are outer cables of the push-pull wire 13 and the operating wire 14; Fixed.

The arm 18a of the unlocking lever 18 extends further downward from the connecting portion of the push-pull wire 13, and this extended portion constitutes an unlocking portion 25 that directly engages with the lock releasing lever 24 of the fuel filler lock device O. are doing. The lock release lever 24 is rotatable around a pivot pin 26, and the tip of one interlocking arm 24a faces the unlocking part 25, and the other interlocking arm 24b is inserted into the engagement hole 28 of the lock pin 27. ing. The locking pin 27 is slidably guided by a guide sleeve 29 fixed to the casing 12, and a spring 30
is biased in the direction of protruding from the casing 12. This lock pin 27 directly or indirectly locks the lid 31 of the fuel filler lock device O in the protruding position shown in the figure, and on the other hand, the push-pull wire 1
3 is pushed out in the direction of arrow C, and as a result, the unlocking part 2
5 pushes the interlocking arm 24a and rotates the lock release lever 24 clockwise in the figure.
b and retreat into the casing 12 through the engagement hole 28 to unlock the lid 31.

As long as the operating device 11 can move the push-pull wire 13 in the forward and reverse directions,
It may have any structure. In the simplest case, the push-pull wire 13 is connected to an operating handle 35 that is rotatable about a shaft 34, as shown in FIG. It is sufficient that the spring means is used to maintain the neutral position at all times.

In this device having the above configuration, when the push-pull wire 13 is pulled in the direction of arrow A using the operation handle 35,
The unlocking lever 18 rotates clockwise in FIG. 2, and as a result, the operation wire 1
4 is pulled in the direction of arrow B opposite to arrow A, and by this movement of the operating wire 14, the trunk lock device T is unlocked. The other push-pull wire 13
When pushed out in the direction of arrow C, the unlocking lever 18 rotates counterclockwise, so that the unlocking part 25 engages the interlocking arm 2.
4a to rotate the lock release lever 24 clockwise. As a result, the lock pin 27 is retracted inwardly into the casing 12 by the interlocking arm 24b, and the lid 31 of the fuel filler lock device O is unlocked.

In this way, with an extremely simple configuration, two systems of locking devices, the trunk locking device T and the fuel filler locking device O, can be unlocked by the single operating handle 35.

FIG. 3 shows another example of the operating device 11. This operating device 11 allows the trunk lock device T to be immediately unlocked by rotating the operating handle 35 in one direction, and prevents the fuel filler lock device O from being unlocked by simply rotating the operating handle 35 in the other direction. The operating handle 35 is coaxially connected to the wire connecting lever 38 by a shaft pin 37 and is pivotally connected to the base 39 so as to be rotatable relative to the wire connecting lever 38. The push-pull wire 13 is connected to the free end of the wire connection lever 38, and the insertion notch 4 of the operating handle 35 is connected to the lever 38.
0 is formed. The insertion notch 40 has an idle notch 41 that is wider than the width of the operating handle 35 and an interlocking notch 42 that is approximately the same width as the operating handle 35. The operating handle 35 rotates idly with respect to the wire connection lever 38 within the range of the notch 41,
When it is in the interlocking notch 42, the operation handle 35
At the same time, the wire connection lever 38 rotates. The operating handle 35 is normally held at a neutral position in elastic contact with the upper end of the idle notch 41 by a spring 43.

According to this operating device 11, the operating handle 35
When pushed up from the neutral position in the figure as shown by arrow D, the wire connection lever 38 rotates together, and the push-pull wire 13 is immediately pulled.
When the push-pull wire 13 is simply pushed down as in step 1, the push-pull wire 13 is not pushed out because the operation handle 35 idles in the idle notch 41. To push out the push-pull wire 13, use the operation handle 35.
A two-stage operation is required, in which the holder is moved into the interlocking notch 42 as shown by arrow F, and then rotated in the direction of arrow E2. Therefore, malfunctions in unlocking the two systems of locking devices are reduced, and there is no risk that the push-pull wire 13 will be pushed out inadvertently.

In the embodiment described above, both the push-pull wire 13 and the operating wire 14 are connected to the front side of the unlocking lever 18, which has the advantage that the operating wire 14 can be particularly short in length. In this embodiment, the operating wire 14 can be constructed from a pull wire, but depending on the configuration of the lock device, a push-pull wire may also be used, and the above configuration is particularly useful in such cases. In the conventional common unlocking device for this type of two-system locking device, the push-pull wire had to be bent gently as shown by the chain line in Fig. 1, so the present invention shortens the wire length. Understand what is possible.

Of course, when the trunk lock device T is provided on the vehicle body side, it is not a good idea to connect the operating wire 14 to the same side as the push-pull wire 13. FIG. 4 shows a skeleton of an embodiment suitable for this case, and the same parts as in the above embodiment are given the same reference numerals. The operating wire 14 is connected to the arm 18a from the rear side opposite to that in the above embodiment, and is connected to the interlocking arm 24 of the lock release lever 24.
a is the unlocking part 2 on the side opposite to the above embodiment.
5, and the interlocking arm 24b extends to the opposite side of the interlocking arm 24a and engages with the lock pin 27. In this embodiment, the relationship between the moving direction of the push-pull wire 13 and the locking devices O and T that are unlocked by this is opposite to that of the first embodiment, but other than that, As in the example, two systems can be unlocked.

As described above, the present invention connects the push-pull wire, which is operated in forward and reverse directions, to one arm of the unlocking lever, and also includes an unlocking part linked to the unlocking member of the first locking device in this arm. With a simple configuration in which the operating wire of another locking device is connected to the other arm of the unlocking lever, it is possible to perform unlocking operations for two systems of locking devices. In particular, the expensive push-pull wire can be used only from the operating device to the unlocking lever, so an inexpensive common unlocking device can be obtained, and the operating wire to be connected to the unlocking lever can be Since there is a degree of freedom in the extraction direction, a common unlocking device can be designed with a high degree of freedom in accordance with the positions of various locking devices in the automobile, the space for disposing operating wires, etc.
