Description

[Detailed explanation of the idea] The present invention relates to an unlocking device for automobiles.

When you go on a long trip with several people in the same vehicle, if the person with the key disappears, you will not be able to open the door, which is very troublesome.

Therefore, in the present invention, an operating lever that can be operated with a fingertip operation is connected to a lever that rotates when a key is operated, and the operating end of the operating lever is a dial type 1, and the key protrusion is exposed and locked. When the lock is unlocked by operating a dial on the key, the lock device for an automobile can be opened by operating the operating lever with a fingertip, so that the door can be opened without a key.

Figure 1 shows the principle of the present invention, in which 1 is a cylinder that rotates the key attached to the outside of the door, 2 and 3 are iron cylinders 1
A lever 4 protruding from each side is an arbitrary door locking device, and the locking lever of the locking device 4 and the lever 2
, 3 is connected to one of the levers 2 by a rod 5.

Therefore, on the outside of the vehicle body, for example, an operating lever 7 that rotates around a shaft 8 is provided at a position that does not exist inside the outer door opening handle, and the operating end 9 of the operating lever 7 is placed at a position that is not located inside the outer door opening handle. It should be protruded from the outside of the door so that it can be operated.

However, the operating end 9 has a protrusion 11 of a dial type key 10.
The configuration is such that the operation end 9 cannot be operated unless the protrusion 11 is engaged and the engagement of the protrusion 11 is unlocked.

Reference numeral 6 denotes a rod that connects the lever 3 and the other end of the operating lever 7.

With the above configuration, by inserting the key into the keyhole of the cylinder 1 from the outside of the door and turning it to the right or left, the locking lever of the locking device 4 can be turned by the rod 5 via the lever 2. , and can be locked or unlocked normally.

In addition, by aligning the dial type key 10 and retracting the protrusion 11, and then operating the operating end 9 of the operating lever 7 with your fingertip, the lock device 7 Since it is possible to activate position 4,
After all, you can open the door without the key.

What is shown in FIGS. 2 to 5 embodies the principle of the present invention shown in FIG. 1.

An example of the lock device 4 is a striker (not shown).
A locking lever 20 has a ratchet 18 for preventing the latch from reversing that engages with the latch and an open lever 17 for rotating the ratchet 18 on the same axis, and also operates a coupling 19 for bringing the open lever 17 and the ratchet 18 into contact with each other.
The locking lever 20 and the lever 2 of the cylinder 1 are connected by a rod 5.

Further, an outer door opening handle 13 is fixed to the outside of the door by a mounting fitting 14, one end of a rod 15 is connected to the outer door opening handle 13 by a shaft 16, and the other end of the rod 15 is connected to the open lever 17.

An operating lever 7 is mounted on a shaft 8 at a position behind the outer door opening handle 13 and can be operated with a fingertip, and the operating end 9 is inconspicuously protruded to the outside of the door. A protruding part 11 of a dial type key 10 is engaged with the end part 9.

Inside the door, the intermediate swinging arm 2 is positioned at the desired position by means of a shaft 22.
1 is fixed on the shaft.

The intermediate swinging arm 21 is a part of the link mechanism, has a rod 6 attached to one end and is connected to the operating lever 7, and has a long hole 23 parallel to the swinging direction at the other end. rod 6
One end of the rod 6 is fitted, and the other end of the rod 6 is connected to the lever 3 of the cylinder 1.

Although the present invention has the above-described structure, when the key 12 is inserted from the outside of the door as shown in FIG. 3 and turned to the right, the lever 2 is rotated to the left in FIG. Rotate 20 clockwise.

Therefore, the locking lever 20 moves upward along the length of the ratchet 18 (L23).

In this state, when the door opening handle 13 on the outside is pulled up, the rod 15 is moved down and the open lever 17 is rotated to the right, and at the same time, the ratchet 18 is also rotated to the right via the connector 19. The door can be opened in the same way.

However, if the key 12 is not present, match the numbers on the dial type key 10 by memory, move the protrusion 11 from the position shown by the phantom line in FIG. When the operating end 9 is moved from the position shown by the solid line in FIG. 3 toward the position shown by the phantom line, the intermediate swinging arm 21 is rotated clockwise in FIG. By pulling up the lever 3 via the lever 6, the same result as operating the key 12 can be obtained by pulling down the lever 2, and as a result, the door can be opened without the key 12.

As described above, the present invention connects the operating lever 7 that can be moved by fingertip operation to the lever 7 that rotates by key operation,
For automobiles in which the protrusion 11 of a dial-type key 10 is exposed to the movable end of the operating lever 7 to lock the door, and the key is unlocked by operating the dial, and then the operating lever 7 is moved to open the door. Since it is a locking device, the door can be easily opened by simply operating a dial, such as when the key is not found, when the person with the key is far away, or when the key is left behind in the car and the door is slightly locked.
