Technical Field
The present invention relates to opening and closing devices for articles, in particular leather articles, generally known as locking devices.
The invention also relates to an article, in particular a leather article, provided with such an opening and closing device
Background
It is known to provide opening and closing devices for articles, in particular leather articles, with a key element and a lock cylinder, which can be locked and unlocked by inserting the key element in the lock cylinder and driving it in rotation, so as to open and close the article. This involves what is often referred to as a lock.
It is also known that opening and closing devices for articles, in particular leather articles, are preferably provided with a box having a mobile lock housing rotating between a first stable position and a second position. An assembly button, also known as a latch pin (tibi), is intended to be inserted into the cassette and to be withdrawn from the cassette when the lock housing is in its second position. This involves a device often referred to as a clasp. When the lock case is in the first stable position, the locking pin is inserted in the box, so that the clasp is closed; when the lock case is in the first stable position and the lock pin is withdrawn from the case, the latch is opened and the lock pin cannot be inserted into the case.
