  • the key is formed there as a flat key, which has on its broad outer surface a control groove for projections of corresponding platelet tumblers. Because this is a reversible key, matching control grooves are embedded on the opposing broad surfaces. For typing the key a rectilinear groove is arranged on the narrow sides, which does not cooperate with platelet tumblers.
  • the invention has for its object to develop a reliable closure device referred to in the preamble of claim 1 species, which is characterized by a high security against break-ins. This is achieved by the measures mentioned in the characterizing part of claim 1, which have the following special significance.
  • the platelet tumblers of the two types are displaceable in mutually different radial directions, it is not readily possible to use the Lock cylinder to open by means of a burglary tool. Depending on how the different platelet tumblers are positioned, one needs different tools whose handling is mutually impeded.
  • control tracks for the two types of platelet tumblers are formed opposite to each other, namely concave on the one hand or convex on the other hand.
  • One type may have control tracks in the form of a control groove and the other in the form of a control rib. Accordingly, the counter-scan pairs in these two types are oppositely formed.
  • the counter-scan pairs consist of the opposite flanks of a radial projection which engages the control groove.
  • the Jacobabtaststellen pairs are formed from a radial recess whose mutually directed flanks serve to encompass the control rib.
  • the platelet tumblers with protrusions can not be adjusted with those burglary tools that would require the platelet tumblers with protrusions. Therefore, closing devices according to the invention are very safe to break.

Abstract

Un dispositif de fermeture comprend une clé (10) et un barillet (30). Le barillet (30) est lui-même constitué par un corps de barillet fixe (31) et par un noyau de barillet (32) monté rotatif à l'intérieur de ce corps. En vue d'améliorer la sécurité anti-effraction, l'invention est caractérisée en ce que deux types de gâchettes à plaquettes (40, 50) sont utilisés dans le noyau de barillet (32), gâchettes dont les déplacements s'effectuent suivant deux directions radiales différentes (41, 51). La clé (10) présente deux surfaces extérieures planes (12, 13) formant un angle entre elles, surfaces à l'encontre desquelles les deux types de gâchettes à plaquettes (40, 50) se déplacent parallèlement. Chacune des deux surfaces extérieures voisines (12, 13) possède une trajectoire de commande linéaire propre (21, 22) qui varie, pour le codage de la clé (10), dans des sections de clé adjacentes, perpendiculairement à la direction longitudinale (29) de la clé. De manière correspondante, les gâchettes à plaquettes (40, 50) présentent une paire de points de palpage associés (42, 52) disposés en une position définie qui, lorsque la clé (10) est insérée, coopèrent avec la trajectoire de commande correspondante (21, 22) et produisent un codage associé analogue dans le barillet (30). Chacun des deux types de gâchettes à plaquettes (40, 50) est en prise avec sa propre trajectoire de commande (21, 22).
