Description

[Detailed description of the invention] The present invention is an attachment case (handbag).
and related to combination locks for similar items.

The key of a combination lock used on attaché cases and similar items is a number of three or four numbers, which is usually used to correctly position a movable member, such as a roulette wheel, in a window. It is formed as a result.

This number, known in principle only to the owner of the attachment case, is visible to third parties both when opening and locking the lock, and also during a relatively long period of time between these two operations, such as during a meeting. may remain visible while the process is taking place. This happens when the owner of the attachment case forgets to mess up the combination of numbers after opening the lock, and even if he does mess up the combination, he doesn't want to overtly show some kind of wariness to the person he's talking to. , or simply trying to avoid re-combining later when locking.

Therefore, in such a situation, the combination lock actually loses its reason for existence. The reason for this is that a person with malicious intent can open an attachment case in a short period of time without destroying it and be able to view the confidential documents inside.

The object of the invention is to provide a combination lock for attachment cases and the like which does not have the disadvantages mentioned above. For said purpose, the lock comprises a plurality of roulette wheels on which a plurality of letters are displayed and a push button which is operable to unlock only when the letters of these roulette wheels are arranged in a predetermined arrangement. , a cover movable between a first position in which the roulette text is covered and a push button is exposed and a second position in which the roulette text is exposed and the push button is covered; is biased to the first position.

Next, some embodiments of the present invention will be described with reference to the accompanying drawings.

The combination lock shown in FIGS. 1 and 2 is for locking an attachment case, and includes a pivoting member 10 equipped with a stopper (not shown) on the inside;
A closure is provided consisting of a fixing plate 12 having an aperture (not shown) which is adapted to engage the aperture and receive a latch such as a locking bolt (not shown).

The lock opening/closing device has three roulette wheels 14,
Numbers 0 to 9 are printed around the roulette. Each roulette wheel can be rotated by hand through a window 15 formed in the fixed plate 12.

The number determined by the position of the roulette wheel 14 is displayed in the window 15. For all but one of the possible numbers, said locking bolt is in the operative position, i.e. the catch is engaged in the opening and the attachment case is locked. is in a state of

On the other hand, when the number displayed in the window reaches a predetermined number known, in principle, only to the owner of the attachment case, the locking bolt is released and the lock is opened.

The lock further has a cover 16 mounted on the plate 12. This cover 16 can be slid over the fixed plate 12 between the two positions shown. That is, it is normally in the first position shown in FIG.
This is applied to the second
can be moved into position. When the force is removed, the return spring allows movement in the opposite direction to the first position.

This lock is provided with a push button 20 that controls the operation of a latch such as a locking bolt.
must be pressed. Therefore, when the number in the window 15 is not to be exposed, the cover 16 covers the button 20, and when the button 20 is to be operated, the number is covered.

As described above, in the character matching lock according to the present invention, it is very difficult for someone else to see the characters for character matching.
