Definitions

  • the invention relates to a lock cylinder with a locking mechanism for selectively blocking or releasing a housing arranged in a movable core, with a guided in the range of movement of the core locking bar, with a provided for biasing the locking bar in the core blocking direction locking spring, with an actuator for Holder of the locking bolt, wherein the directions of movement of the locking bolt and the actuator are substantially transverse to each other, and with control electronics for controlling the actuator, wherein the actuator is fixed with its locking bar remote end in the housing and the actuator for holding the locking bolt by clamping in which the movement of the core releasing position and for releasing the movement of the locking bar is formed in the movement of the core blocking position.
  • a locking mechanism in which in the releasing position of the core, a blocking element is held by an electromagnet in a housing.
  • the blocking element is biased in the direction of the core.
  • the electromagnet moves a pin which penetrates into an annular groove of the blocking element.
  • Such a lock cylinder with a locking mechanism is for example from the DE 32 08 818 C2 known.
  • the locking bar is designed pin-shaped and protrudes in obliquely to the lateral surface expiring domes of the core.
  • a bearing axis of the actuator and the locking bolt are arranged in parallel, so that when driving the piezoelectric element, the actuator is pressed into a locking recess of the locking bolt.
  • a return spring pulls the actuator back out of the recess.
  • the piezoelectric element must be permanently driven to hold the actuator in the locking recess of the locking bar.
  • the control so that the actuator is moved out of the return spring from the locking recess of the locking bolt.
  • the piezoelectric element of the locking spring is arranged opposite and thus moves a structural unit of actuator and locking bolt against the force of the locking spring.
  • a disadvantage of the known locking mechanism that the actuator is arranged either opposite to the locking spring or its own return spring, so that when releasing the movement of the core of the actuator against the force of at least one spring must be moved. This leads to a high energy consumption of the locking mechanism. Furthermore, the constant readiness of the control electronics and a constant control of the piezoelectric element requires a very high energy consumption. Since such locking mechanisms are often used in front doors of commercial or residential areas and a longer period without power should be functional, high energy consumption is very disturbing.
  • a locking device in which a strike plate or a bolt has the actuator.
  • the actuator may, for example, a piezoelectric element, a magnetostrictive actuator or a shape memory actuator and pushes a lever against the force of a spring against a profile. Even with this locking device, the movement of the actuator against the force of the spring leads to a very high power consumption.
  • the invention is based on the problem of designing a lock cylinder with a locking mechanism of the type mentioned above so that it has a particularly low energy consumption.
  • the actuator is at least partially formed as a piezobender or magnetostrictive element and that the locking bolt during insertion of a key in a closing channel or the initial rotation of the core is displaced and projecting into the range of motion of the actuator unevenness to move of the actuator, that the actuator has a pulse generating during its movement, preferably piezoelectric element and that the control electronics can be activated by the pulse generated by the movement of the actuator.
  • the actuator can move freely and thus without obstruction of a spring.
  • the energy required to move the actuator is therefore particularly low.
  • the actuator is only activated when a release of the locking mechanism is to take place. Because the nucleus is usually blocked in the majority of the time Position remains, this leads to a strong reduction in energy requirements.
  • On the arranged on the locking bar locking recess can be omitted, since the locking bar is held by clamping forces. In this way, the path that the actuator must travel between the position blocking the movement of the core and the position which releases the movement of the core is kept particularly small. This leads to a further reduction in the energy requirement of the actuator.
  • the entrapment of the locking bolt by the actuator in the movement of the core releasing position also leads to very low holding forces of the locking bolt.
  • the locking bar is clamped between a single actuator and the housing.
  • the locking cylinder according to the invention requires a particularly small space when the actuator is plate-shaped and fixed with its remote from the locking latch end in the housing and when a free end of the actuator is aligned against the locking bar in its movement of the core releasing position.
  • the locking mechanism can be particularly easily arranged in a profile lock cylinder.
  • the piezoelectric Element is designed plate-shaped and essentially forms the actuator.
  • Clamping the locking bolt or its entanglement with the actuator can be easily avoided according to another advantageous embodiment of the invention, when the control electronics is formed at an intended blocking of the core for reverse control of the actuator to release the movement of the locking bolt.
  • the bumps arranged on the locking bar require a particularly low design effort, if the lateral surface of the locking bolt is bulbous or wavy.
  • the clamping force required to hold the locking bolt can be easily adjusted according to another advantageous embodiment of the invention, when an actuator for adjusting the position of the locking bolt relative to the actuator is arranged on the opposite side of the actuator of the locking bolt.
  • the locking spring has an adjusting element for adjusting the biasing force of the locking bolt.
  • the adjusting element is formed as screwed into a receiving the locking bolt channel grub screw or a ball pressed therein.
  • High holding forces of the locking bolt with a particularly low energy consumption of the actuator can be easily generated according to another advantageous embodiment of the invention, if at least one friction lining on the lateral surface the locking bolt and / or the actuator and / or a guide of the locking bolt is provided.
  • the friction lining is preferably formed as a coating of the corresponding component.
  • the mounting of the lock cylinder according to the invention is particularly simple if the housing has a transition into a stepped bore pocket and if guided in the stepped bore of the locking bolt and is arranged in the pocket of the actuator. By this design also the locking bolt can be secured by a shoulder of the stepped bore from falling out.

  • the actuator 11 and the control electronics 16 are arranged in a pocket 20 of the housing.
  • the locking bolt 13 is guided longitudinally displaceable in a stepped bore 22.
  • the slider 21 Upon insertion of the key into one of the closing channels 4, 5, the slider 21 is moved and pushes with the ramps 18, the displacement element 19 down. In this case, the locking bar 13 is also pressed down until it comes out of the range of movement of the core 2. For clarity, the movements of the slider 21 and the locking bar 13 in the drawing are indicated by arrows.
  • the code receiver 9, 10 detect signals from transponders of the key and These lead to the control electronics 16.
