Abstract

PROBLEM TO BE SOLVED: To open and close a lid of a trunk together with a lock body attached to the lid, by providing the lock body thereto with a hook member adapted to be engaged with and disengaged from a locking plate attached to the trunk body. SOLUTION: A temporarily locking member 15 at the lower end of a lock body 1 is pulled, it is separated from a step part 17 of a lock plate 4. When the lock body 1 is lifted up about a shaft 7 as a fulcrum in this condition, the shaft 7 is moved downward being pulled by a coil spring 12, and accordingly, a stop piece 10 is opened about a fulcrum shaft 9 so that a hooking member 5 is locked to a lock part 6 of the locking plate 4 so as to effect unlocking. Further, when the lock body 1 is pushed in a locking direction in an opening condition, the shaft 7 is elevated while the coil spring 12 is extended so that the stop piece 10 is closed, and as a result, a rotary bearing receiving step part 3a of the hook member 3 is made into press-contact with the fulcrum shaft 9. Further, the hooking member 5 is locked to the hook part 6 of the lock plate 4 so as to effect locking. With this arrangement, the locking and unlocking can be made respectively by one motion.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock used for a trunk.

[0002]

2. Description of the Related Art Due to the structure of a conventional trunk lock, the lock body is attached to the trunk body side and the locking plate is attached to the lid side. Therefore, the operation of unlocking the lock body and the two operations of opening the lid of the trunk are required.

[0003]

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the complexity of the conventional two operations, and to unlock the lock body and at the same time, to open the trunk lid in one operation. To provide.

[0004]

In order to solve the above-mentioned problems, the present invention has a lock main body attached to the lid side of the trunk and an engaging plate attached to the trunk main body side. Is as follows: The lock main body is attached to the lid side of the trunk, and the locking plate is attached to the trunk side of the trunk. The fixed base plate is fixed to the lid body of the lock main body, and the hook is attached to the hook portion provided on the locking plate. Equipped with a hook member that forms a hook, the lock body and the shaft that pivotally connects the upper ends of the hook members are shielded and supported on the fixed base plate so that it can move up and down, and the tip of the stop piece that is pivotally mounted on the fixed base plate is pivoted. Connected to the inside of the lock body by a shaft, and forming a rotary bearing stop for stabilizing the hook member when locking. Then, a temporary fixing member having a hook is pivotally attached to the lower end of the lock body by a shaft, and a spring acts in a direction in which the hook engages with a step formed on the locking plate.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 in the drawing is a lock body to be attached to a lid 50 side of a trunk, which is provided with a fixed base plate 2 and a hook member 3 as shown in FIG. As a locking plate to be fixed, a hook portion 6 for locking the hook 5 formed on the hook member 3 is provided as shown in FIGS. As shown in FIG. 2, the lock body 1 pivotally mounts the hook member 3 on the upper end by a shaft 7, and the shaft 7 is shielded by the inverted L-shaped piece 8 of the fixed base plate 2 and can move up and down. Also, a stop piece 10 is pivotally attached to the lower end of the base plate 2 by a fulcrum shaft 9, and the tip end of the stop piece 10 is connected to the inside of the lock body 1 by a rotary shaft 11, and when the lock is made, the hook member 3 is provided.
Is pressed in as shown in FIG. At that time, the shaft 7 moves upward, the stop piece 10 pivots around the fulcrum shaft 9, and hits the catch step 3a of the hook member 3 so that the hook 5 hooks on the hook 6 of the locking plate 4. It stabilizes in the state. Therefore, the other end of the coil spring 12 having one end hooked on the shaft 7 is hooked in the hooking hole 13 formed in the fixed substrate 2, and the locking action is stable by the action of the coil spring 12 at the time of locking. A temporary fixing member 15 having a hook is pivotally attached to the lower end of the lock body 1 by a shaft 16, and the hook 14 is engaged with a step portion 17 formed on the engaging plate 4 to act in the engaging direction. 18 is wound around the shaft 16. Reference numeral 19 is a key member having a key hole 20 provided in the lock body 1, and when the hook piece 21 at the tip is turned 90 ° by a key, the hook piece 21 is separated from the hook U-shaped portion 22 of the locking plate 4.

[0006]

In the locked state shown in FIG. 2 (a), the lock body 1
When the temporary fixing member 15 at the lower end of the lock plate 4 is pulled toward the front with a fingertip, it is disengaged from the step 17 of the locking plate 4, so that the lock shaft 1 is used as a fulcrum.
When the shaft is lifted, the shaft 7 is pulled by the coil spring 12 and descends, the stop piece 10 opens around the fulcrum shaft 9, and the hook member 3
The hook 5 is disengaged from the hook 6 of the locking plate 4 and unlocked (see FIG. 2 (b)). When the lock body 1 is pushed in the closing direction in the open state of FIG. 2B, the shaft 7 rises while extending the coil spring 12, the stop piece 10 is also closed, and the fulcrum shaft 9 receives the hook step portion of the hook member 3. 3a comes into pressure contact with each other, and the hook 5 is locked to the hook 6 of the locking plate 4. That is, it can be locked and unlocked in one operation.

[0007]

According to the present invention, the lock main body is attached to the lid side of the trunk and the locking plate is attached to the trunk main body side, and the lock main body is unlocked and at the same time the trunk lid is opened. Since it can be opened by one operation, the operation is quicker and easier than the conventional one requiring two operations, and the practical value as this kind of trunk lock is remarkably improved.
