摘要:
A security lock comprises a closure cylinder with a cylinder housing (2, 3) and at least one cylinder core (4) mounted in a through-aperture (11) in the housing so as to rotate; the cylinder core is inserted into the aperture from the rear side and provided at its rear end with an enlarged section (13). Tumblers are set by a spanner inserted in a key channel. A catch (14) is provided on the rear side of the enlarged section (13) and is provided with the guide means for coupling the cylinder core (4) to a drive element (15).
摘要:
This invention concerns a pin tumbler consisting of housing pin (5, 20, 25), a core pin (6) and a compression spring (7) which is seated in the housing (3) of the rotating lock cylinder (1), against the force of which the pin tumbler (4) releases the cylinder core (2) with the rotational movement of the key introduced into the key channel (15). The housing pin (5, 20, 25) has a recess around its circumference directly behind the face (11) which abuts the core pin (6), in such a way that an edge (16) with an acute angled cross section is formed. The housing pin (5) locks securely even with a small progressive step of for instance 0.5 mm.
摘要:
The rotary locking cylinder described has a stationary part (2) and a rotating part (3), plus several tumblers (8) each with a core pin (10) and a housing pin (9). Mounted in the rotating part (3) is at least one locking element (22) which can be displaced approximately at right angles to the core pin (10) of a tumbler (8) and in its position of rest engages in a recess (20) in the stationary part (2). The recess (20) in the stationary part (2) has a control surface (19) designed so that, when the unlocked stationary part (2) is rotated, the locking element (22) is moved towards the core pin (10). Machined in the surface (10b) of the core pin (10) is a groove (12) such that, with the core pin (10) inserted, after the rotating part (3) has rotated through a relatively small angle, the locking element (22) can be pushed far enough into the groove (12) for it to be lifted out of the recess (20) in the stationary part (2) and, with the core pin (10) not inserted, the locking element (22) essentially cannot be pushed out of its position of rest and rests against the surface (10b) of the core pin (10).
摘要:
The rotary barrel has a barrel housing (2) and a rotor (3) fitted to rotate therein and several locking pins (5, 6) which are arranged for the release of the rotor (3) by a key inserted in a key channel (4) of the rotor (3). At least one locking pin (5) has a core pin (12, 20, 23), the end (13) of which, which projects forward and into the key channel (4), is formed in such a way that, in the event of unauthorised attempts at opening the lock by a vibrating instrument, it is bent, deformed or broken off.

Der Drehschliesszylinder besitzt einen Stator (7) und einen in diesem drehbar gelagerten Rotor (3) sowie eine den Stator (7) umschliessende Hülse (2). In den Mantelteil (2b) der Hülse (2) ist eine Oeffnung (2a) eingearbeitet, in welche eine am Stator (7) gelagerte Sperrvorrichtung (8) ausklinkbar eingreift und die Hülse (2) lösbar mit dem Stator (7) verbindet.
