Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trunk lock which is locked by hooking a latch fitting pivoted on the lock body onto a temporary latch plate fixed to the lid side, and is mainly used for trunks attached to the rear of a motorcycle. This invention relates to a trunk lock suitable for use.

Locks for trunks fixed to the rear seats of motorcycles have been devised in the past, but conventional ones are designed to be locked using a key and are not equipped with temporary locks. Therefore, unless the vehicle is locked, the lid may open unexpectedly due to the movement of the vehicle, making it necessary to carry the key at all times.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a trunk lock which can be locked without using a key and which prevents the temporary release of the trunk lock, which eliminates the above-mentioned drawbacks of the prior art.

In order to satisfy the above object, the present invention is constructed as follows.

That is, the present invention includes a lock case in which a locking metal fitting that locks on a locking plate fixed to the lid side is rotatably supported,
The lock case is rotatably attached to a base plate attached to the main body, and the lock case is equipped with a temporary locking claw that engages with a locking frame set up on the base plate. A code lock for locking the mating claws is installed inside, a part of the code ring is exposed through the window hole on the surface of the lock case, and one end of the locking piece in contact with a circular pressing piece integral with each code ring is used for the temporary fixing. A trunk lock in which a leaf spring is attached to the inner case, connected to the engagement pawl, the other end of which extends through a flat hole in an inner case built into the lock case, and pushes a locking piece in a direction opposite to the flat hole. be.

Next, embodiments of the trunk lock according to the present invention will be described with reference to the drawings. In the figure, 1 is a lock case, and code rings 2a, 2b, 2c that make up the code lock 2 are 1.
It is pivoted by a book shaft 3. A latch 4 is pivotally attached to the lock case 1 by a shaft 5, and a latch plate 6 has a tip hook 4a of the latch 4 attached to the trunk lid side.
In order to engage with the engagement hole 7 of the lock case 1, the lock case 1 is pivoted by a shaft 10 to bearing pieces 9, 9 which are integral with a base plate 8 fixed to the trunk body side, and rotated about the shaft 10 as a fulcrum. The latch fitting 4 protrudes in the direction of the latch plate 6. Furthermore, an engaging claw 13 that is hooked into the engaging hole 12 of the locking frame 11 provided upright on the base plate 8 is built into the lock case 1.
The operation knob 14 integrated with the lock case 1 is made to protrude from the window hole 15 of the lock case 1, and the engaging claw 13 and one guide frame plate 1
6 along the inner case 18 housed inside the lock case 1, and its tip is fixed to the lock case 1 with a screw.Insert it into the flat hole 19 of the inner case 18, and insert the protrusion 1 at the tip.
Fit the coil spring 21 into the stopper 20 provided in the recessed notch 19' following the flat hole 19.
is stabilized in the handle removal notch 19', and the coil spring 21
Due to the resilient force, the operating knob 14 always protrudes from the window hole 15, and the engaging claw 13 is disengaged from the locking frame 11, allowing the lock case 1 to rotate. In this state, if you move the lock case 1 in the closing direction, the engaging claw 1
The engaging claw 13, the operating knob 14, and the guide frame plate 16 are once moved by the inclined surface 13' of No. 3 against the coil spring 21, and then the engaging claw 13 is engaged with the engaging frame 11 by the coil spring 21 again. They are then temporarily fastened together.

In the present invention, the temporary locking mechanism is locked by the code lock 2, and all the code wheels 2a, 2b, 2
The flat part 2 of the circular pressing piece 22 protruding from one side of c
The operating knob 14 can be pressed only when all of the locking pieces 2' are in contact with the locking piece 23. That is, the small hole 24 at one end of the locking piece 23 was fitted into the protrusion 25 of the engaging claw 13 to connect them, and the other end was fixed to the inner case 18 with a screw 26 so as to face the flat hole 19 of the inner case 18. The leaf spring 27 is pressed against the lower surface of the locking piece 23.

Therefore, as shown in FIG.
3, the tip of the locking piece 23 is located under the flat hole 19, and the engaging pawl does not move even if the operating knob is pressed. When the flat portions 22' of the circular pressing pieces 22 of all code wheels come into contact with the locking piece 23 as shown in FIG. Now you can open the lock. Matching wheels 2a, 2b, 2
A V-shaped groove 28 is formed between each numeral in C, and this enters a leaf spring 29 attached to the inner case 18, and each code wheel is stabilized at that position. In the figure, 30 indicates an exposure hole for a code ring provided in the lock case 1.

According to the present invention, when each code ring is placed in the unlocked position and the operation knob 14 is pressed, the lock case 1 moves freely.
Then, the latch fitting 4 is locked with the lock 6, and the code rings 2a, 2b, 2c are turned to lock the lock. When unlocking, all code wheels are set to set numbers and the operation knob 14 is pressed to make the lock case 1 rotatable and unlocked. Therefore, temporary fixing cannot be performed if the code does not match the set position.

As described above, the present invention can be locked without using a lock, and can be temporarily secured if necessary, and is more practical than conventional locks of this type, and there is no particular risk of losing the key. It is suitable as a trunk lock for a motorcycle that is ridden. The locking structure of the code ring is extremely simple.
