Mechanisms, assemblies and electronic locking system
Release mechanism ( 10 ) for an electronic locking system ( 156 ), wherein the release mechanism ( 10 ) is configured such that an input member ( 14 ) and an output member ( 16 ) are locked against relative rotation and can rotate together within a locking ring opening ( 22 ) when a locking member ( 20 ) is located in an input member recess ( 42 ) and in an output member recess ( 46 ), and such that the output member ( 16 ) is released to rotate relative to the input member ( 14 ) when the locking member ( 20 ) is located in the output member recess ( 46 ) and in a locking ring recess ( 26 ). A freewheel mechanism ( 66 ) and assemblies ( 98 ) for an electronic locking system ( 156 ) are also provided.
1. Assembly for an electronic locking system, the assembly comprising:
a shaft arranged to rotate about a rotational axis from a starting position;
a spring arranged to store mechanical energy from rotational displacement of the shaft from the starting position; and
a release mechanism arranged to release the mechanical energy stored in the spring to an output member;
wherein the spring is preloaded when the shaft is in the starting position.
2. The assembly according to claim 1 , wherein the spring is preloaded to exert a torque on the output member when the shaft is in the starting position.
3. The assembly according to claim 1 , wherein the output member is locked against rotation when the shaft is in the starting position.
4. The assembly according to claim 1 , wherein the release mechanism is configured to release energy stored in the spring to a rotation of the output member.
5. The assembly according to claim 1 , wherein the shaft is configured to be rotated about the rotational axis by actuating a handle.
6. The assembly according to claim 1 , wherein the spring is preloaded with a torque of 1 to 1.5 Nm.
7. The assembly according to claim 1 , wherein the spring is a torsion spring encircling the shaft.
8. The assembly according to claim 1 , wherein the spring is a helical torsion spring.
9. The assembly according to claim 1 , further comprising a stationary structure; wherein the shaft is arranged to rotate within the stationary structure about the rotational axis; and wherein the shaft extends through the stationary structure along the rotational axis such that a handle can be fixed to the shaft at each side of the stationary structure.
10. The assembly according to claim 9 , wherein the stationary structure is constituted by a housing.
11. The assembly according to claim 1 , further comprising:
a freewheel mechanism; and
an electric generator;
wherein the freewheel mechanism and the electric generator are hollow and the shaft passes therethrough along the rotational axis.
12. The assembly according to claim 11 , wherein the spring is a torsion spring; and wherein the spring encircles the shaft and passes through the electric generator and optionally through the freewheel mechanism.
13. Electronic locking system comprising an assembly according to claim 1 .
