Abstract
The coding assembly comprises a body, a removable cross bar and a key having coding pins. According to the invention, the side surface of the homing head is provided with at least one longitudinal rib. The cross-sectional profile of the longitudinal rib corresponds to the cross-sectional profile of the coding recesses, the depth of which corresponds to the height of the longitudinal rib. Moreover, each securing pin has at least one additional recess, the cross-sectional profile of which corresponds to the cross-sectional profile of the longitudinal rib, and the depth is smaller than the height of the longitudinal rib.
Claims10
A coding assembly of a locklike device, comprising:
- a body;
- a main cavity in said body;
- additional cavities in said body, communicating with said main cavity, the axis of each of said additional cavities being perpendicular to the longitudinal axis of said main cavity;
- securing pins, each of which is arranged for limited longitudinal displacement in each of said respective additional cavities, and wherein each of said securing pins moves within said respective additional cavities by gravity;
- coding recesses, each of which is provided in the side surface of the respective one of said securing pins;
- a removable cross bar;
- a homing head of said cross bar designed to be received in said main cavity of said body and to interact with said securing pins;
- at least one longitudinal rib provided on the side surface of said homing head and having a cross-sectional profile corresponding to the cross-sectional profile of said coding recesses, the depth of which corresponds to the height of said longitudinal rib;
- at least one additional recess provided in the side surface of each of said securing pins and having a cross-sectional profile corresponding to the cross-sectional profile of said longitudinal rib, the depth of each additional recess being smaller than the height of said longitudinal rib;
- a key;
- coding pins of said key, designed to interact with said securing pins and to allow free movement of said homing head out of said body owing to their location in one plane passing through the longitudinal axis of said homing head and the longitudinal rib thereof.
