[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved trunk lock.

[0002]

2. Description of the Related Art Conventionally, there are left and right trunk lock bodies fixed to a trunk main body side and left and right locking plates attached to a lid side. A hook having a reversing spring acting on the plate, and an operating lever for releasing the hook engaged with the locking plate,
A trunk lock having a structure in which the operation lever is connected to a release plate for turning a hook in the opposite direction against the reversing spring is already described in Japanese Patent Application Laid-Open No. 2-272183. This trunk lock, when the lid of the trunk is closed, the hooks of both left and right trunk locks are rotated by the locking plate on the lid side,
It locks automatically, is easy to use, and has the benefits of a trunk lock.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a trunk lock in which the mechanism is simplified, the operation is performed more smoothly, and the performance is further improved as compared with the conventional trunk lock.

[0004]

The means of the present invention are as follows. A trunk lock body fixed to the trunk main body side, a locking plate attached to the lid side, the trunk lock main body is operated by the lid side locking plate, and a hook acted by a reversing spring for locking; A trunk lock having an operating lever for releasing the hook, and a tip of an elastic strip attached to the operating lever connected to a release plate for rotating a hook in a reverse direction against the reversing spring.

[0005]

When the open lid is closed, the locking plate 2 enters the gap 4 from the insertion opening 3 of the lock body 1 fixed to the trunk main body,
The hook 5 pivots about the pivot 7 and the upper end of the hook 5 is quickly engaged with the locking plate 2 by the reversing spring 9 to lock the trunk lock. When unlocking, the undulating member 27 is pressed, and then the operating lever 16 is pulled, whereby the elastic strip 19 is pulled, so that the release plate 13 cooperates, and the notch 14
At 4a, the hook 11 of the hook 5 is pushed and the hook 5 is returned to the unlocked position (FIG. 2) against the reversing spring 9.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a pair of trunk lock bodies attached to the left and right sides of a trunk main body, and 2 denotes a locking plate fixed to a lid. The trunk lock main body 1 is provided with a hook 5 to which the locking plate 2 is engaged and a safety cam 6 for stopping the hook 5 from moving irregularly in a space 4 below the insertion opening 3 into which the locking plate 2 is inserted. It is pivotally connected, and one end of a reversing spring 9 is connected to the hook 5, and the other end is attached to a hooking piece 10 provided on the trunk lock body 1. Hook 5
Are the protrusions 11 and 12 provided at the upper end of the safety cam 6,
Notch 1 of release plate 13 slidably housed inside
4 and 15, and the projection 1 is moved by the release plate 13 at one end edges 14 a and 15 a of the notches 14 and 15.
The hooks 5 and the safety cam 6 are rotated by pressing the buttons 1 and 12 to unlock the hook. Reference numeral 16 denotes an operation lever for operating the release plate 13. The operation lever 16 is pivotally supported by a longitudinal axis 17 on a mounting piece 18 of the trunk lock main body 1 adjacent to the trunk lock main body 1 and connected to one end of the release plate 13. The tip of the elastic strip 19 is connected to a support shaft 20 on the inner surface of the operation lever 16 via a connecting piece 21 and the operation lever 16 is operated with the vertical axis 17 as a fulcrum (see FIG. 4). Is guided by a guide rotator 23 pivotally supported by a shaft 22 to a mounting piece 18 and pulled to slide the release plate 13, and at the side edge 14 a of the notch 14, the protrusion 11 of the hook 5 is connected to the reversing spring 9. Push in opposition to unlock as shown in FIG. In the figure, reference numerals 24 and 25 denote slots formed in the release plate 13 to avoid the pivots 7 and 8 of the hook 5 and the safety cam 6,
Reference numeral 26 denotes a spring acting on the safety cam 6, and reference numeral 27 denotes an undulating member which comes into contact with the open end 16a of the operation lever 16, and is pivotally mounted on a receiving piece 28 of the trunk lock main body 1 with a pin 29, and is wound around the pin 29. Is made to contact the up-and-down member 27 and the other end to the main body side, so that the up-and-down member 27 always contacts the open end 16a of the operation lever 16 so that the operation lever 16 cannot be operated (see FIG. 1). When the operation is performed, the undulating member 27 is pushed against the spring 30 as shown in FIG. 4, and the operation lever 16 is opened. In the figure, a lock plate 31 is slidably mounted in the trunk lock main body 1 and a lock piece 32 is provided upright at a tip end portion. When the lock plate 32 is moved from the open state of FIG. 1 to the position of FIG. 5, the undulating member 27 is locked by the lock piece 32 in the locked state, and cannot be unlocked.

[0007]

According to the present invention, the operation lever 16 and the release plate 13 are connected to each other by the leaf spring-shaped elastic strips 19, and the guide rotator 23 for guiding the movement of the elastic strips 19 is incorporated. As a result, the unlocked state can be achieved with a very simple structure, and there is an effect that the device can be used for a long time without fear of failure.
