Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a padlock used for a storeroom, a locker for changing clothes, etc. More specifically, one padlock is provided with two kinds of locking means, and one of them is operated by a key. On the other hand, the present invention relates to a padlock which requires the operation of matching a secret number.

[0002]

2. Description of the Related Art Conventionally, padlocks used for storerooms, lockers for changing clothes, etc. are of a type provided with a cylinder lock that requires the operation of so-called keys and a combination type that does not use the keys, that is, a plurality of rings, respectively. Each number ring engraved with a number from 0 to 9 is provided on the body of the padlock, and each number ring is adapted to match the release number with a predetermined position according to the personal identification number. Therefore, when each numbering ring matches the predetermined position in the release number, the multiple protrusions (the same number of protrusions as each numbering ring) formed on one of the latch members at the top of the padlock body are inside the numbering ring. Of 1
Since it can be pulled out from the notch formed in the place, the other of the latches can be detached from the main body at this time, and the latch member is released.

More specifically, in the former type of key cylinder lock, an old type and a new type are commercially available. The old-type padlock is an engaging member that is always urged by a spring into a notch that is line-backed to one of the U-shaped latch members by a protrusion formed at the tip or intermediate portion of the key. Can be moved. Therefore, in such a state, one of the latch members can be pulled out from the padlock body to be unlocked. In the new type,
The padlock body has a so-called cylinder lock with multiple pin tumblers or disc tumblers.
By using a duplicate key for such a cylinder lock, the rotor in the cylinder lock can be rotated together with the rotation operation of the key.

Therefore, the cam formed at the tip of the rotor moves the engaging member, which is always urged by the spring and engaged, into the notch formed in one of the U-shaped latch members as described above. It is like this. In such a state, one of the latch members can be detached from the padlock body so as to be free. Thus, the latch member can be unlocked by moving the latch member in the pulling-out direction.
Also, if the key is rotated in the opposite direction to remove it from the cylinder lock, the free latch member is inserted at the position of the concave portion of the main body, that is, at the original position. The engaging member is automatically engaged with the notch of the latch member while being biased by the spring.

Therefore, the locking member can be locked by moving the engaging member to the notch of the latch member. The latter is a padlock having a so-called numbering that does not use a so-called key, but since a plurality of rotatable numberings are fitted to the body of the padlock body, such a padlock is used by the user for each numbering. While visually observing the ring number, rotate it by hand and match the release number with the release position mark engraved on the padlock body.The lock release provided at one position of the lock part inside each number ring. The gradual portions are respectively located at the engaging portions formed on the latch member. .

In such a positional relationship, if the latch member is slightly pulled out from the padlock body, one end of the latch member is pulled out as described above, so that the latch member can be released. If the user wants to lock the numbering member, push one end of the latch member, that is, the free end side, into the recess on the padlock body side, and then manually touch each numbering ring so that the release numbers of the numbering rings vary. If it is rotated, the notch of the numbering will be disengaged from the release position, so that the latch member can be fixed and can be locked.

[0007]

Since the former padlock uses a key for a cylinder lock, the key may be duplicated by a third party or the key may be stolen. If this key is illegally used, it will be stolen. There is a drawback in that it cannot be prevented. In the latter case, the cancellation number is known by a third party, or at night or in a dark place, the number (number) engraved on each number ring is dark or invisible, or has the drawback that it is difficult to see. It was Also, as described above, in the padlock that eliminates the defects of both and provides the features integrally, the stroke that the latch member moves is the combination lock.

Since the cylinder lock side has a lock mechanism, the height must be longer than that of the cylinder lock side.
There is also the disadvantage that the padlock body cannot be miniaturized accordingly. So in a padlock with a cylinder lock,
Since the locking member that is moved by operating the key is engaged with and disengaged from the notch formed in one of the latch members to enable locking and unlocking, the latch member on the side having this engaging portion when unlocked. Because it requires a stroke within the range of movement until it is removed from the recess of the padlock body and becomes free, the size of the padlock body must be increased in size.

In order to eliminate such drawbacks, an object of the present invention is to provide a padlock main body with a lock device operated by a key and a mechanism for manually adjusting characters, so that a latch member can be double-locked. In addition, the moving distance of the latch member can be reduced.

[0010]
