Title:
DOOR LOCK AND THE KEY THEREFOR
Document Type and Number:
WIPO Patent Application WO/2003/060263
Kind Code:
A1
Abstract:
The inventive door lock comprises a body (1) provided with a keyhole, and the following parts arranged in said body: a locking bar (36), a unit for fixing said locking bar provided with stoppages (17, 13) arranged on said locking bar and a control unit (25), a movable element (42) provided with a mechanism for meshing with the locking bar having a meshing element (52) and elements (6, 55) which retain said meshing element in a working position and interact with secret elements (44, 46). Said secret elements have coded sections provided with a relief surface for interacting with elements (66, 67) which have the parts projected inside the keyhole in such a way that they interact with the key. Said key comprises a cylindrical bar (71) provided with circular coded parts embodied thereon and having a relief surface (73). The key being turned inside the keyhole, the movable element (42) is displaced in a direction towards the recess of the locking bar and meshed to the mesh control unit (25) with the aid of the meshing element (52), thereby unlocking the locking bar (36) and recessing it in the body (1) of the lock. During that operation, the secret elements (44, 46) are superposed with the coded parts thereof and displaced along bosses with the aid of the wheels (57, 69) of the elements (66, 67), but remaining fixed with respect to the meshing element (6) in such a way that recesses of the coded parts of the secret elements (44, 46) coincide with the bosses of the code parts of the key and vice versa, the bosses of the coded parts of the secret elements (44, 46) coincide with the recesses of the coded parts of the key. The meshing element (52) is permanently meshed with the mesh control unit (25). In the case of a force opening devoid of the functional operations which are performed by the coded parts of the key in the keyhole, the secret elements (44 and/or 46) being actuated by springs or by an external action through the keyhole, rotate clockwise or counter-clock-wise, act on the element (6) by the bosses thereof and turn said element in a counter-clockwise direction. The meshing element (52) being disengaged from the element (25), the recessing of the locking bar in the body (1) is stopped.
