Arrangement of a plurality of locking elements, in particular for lock cylinders

Technical field

The invention relates to a structural arrangement of a plurality of locking elements, in particular for lock cylinders and locks in which the axes of movement of the locking elements are in the same plane and the locking elements are compressed by a key in one direction.

BACKGROUND OF THE INVENTION

At present, a number of lock designs and lock inserts are known in which a plurality of spring-loaded locking elements, consisting of spring sets, locking pins, tumblers, slats or segments, providing a movement element, i.e. a rotating drum or sliding block, are housed in one or more rows. , against rotation or displacement without inserting the appropriate key. In all known embodiments, the bores in the movement elements are formed in such a way that the contact surfaces of the spring-pushed locking elements are substantially aligned in a plane perpendicular to the axis of movement of the elements when the key is not inserted. The disadvantage of these solutions is that this arrangement allows the locking elements to be overcome by some methods and to open the lock.

The essence of the technical solution

This drawback largely eliminates the arrangement of a plurality of locking elements, in particular with locks and locks, comprising at least two locking elements in which the axes of movement in the guide cavities are in the same plane and these locking elements are compressed by the key in one direction. The principle of the solution consists in that the stop surfaces of the locking elements are designed such that the top of the contact surface of the at least one locking element is located in a different plane perpendicular to the direction of movement of the locking elements and parallel to the shear plane. one perpendicular locking element and which is perpendicular to the direction of movement of the locking elements and at the same time parallel to the shear plane between the movement element and the body.

Description of the figure in the attached drawing

A particular example of the arrangement according to the invention is schematically shown in the attached drawing showing a longitudinal axial section through a group of locking elements formed in a rotary drum of a cylinder lock cylinder.

Examples of technical solution

The construction shown is formed by a longitudinal body 1, in whose housing 101 the movement element 2, for example a rotating drum, is mounted. In the core 102 of the body 1 a set of at least two parallel guiding holes 103 is formed, against which a plurality of guiding cavities 21 are formed in the movement element 2 In the guiding holes 103 and guiding cavities 21 a group of spring-loaded locking elements 3 formed according to FIG. springs 31, locking pins 32 and tumblers 33. The guide cavities 21 are arranged in the movement element 2 in a plane passing through the axes of direction of movement of the locking elements 3. In the guide cavities 21 contact surfaces 211 are formed to abut the spring 31 of the tumblers 33 when the key 4 is not inserted. The contact surfaces 211 are formed such that the apex of the abutment surface 331 of the at least one locking element 3 is located in a plane β other than the γ plane passing through the apex of the abutment surface 331 of the at least one adjacent locking element 3 and perpendicular to the direction of movement prv 3

Simultaneously parallel to the shear plane and between the movement element 2 and the body 1, as shown in the drawing for two of the central locking elements 3.

When the key 4 is inserted into the movement element 2, the locking elements 3 are gradually compressed until they all stabilize in the shear plane and the movement element 2 and the body 1, thereby enabling the lock to be unlocked. When the key is removed, the locking elements 3 return to the home position.

The described embodiment is not the only possible solution of the arrangement, but the locking elements 3 may be of different shapes and designs, the contact surfaces 331 of the locking elements 3 need not coincide with the contact surfaces 211 of the guide cavities 21 and the group may comprise a different number of locking elements 3.

Industrial Applicability

The arrangement according to the invention can be used for different types of locks and lock inserts with spring-loaded locking elements.
