Definitions

• the present invention concerns an electronic lock.
• An electronic lock is a lock where electronic circuits are utilized for determining the identity of a presented key and for releasing an opening movement of essentially ordinary mechanical details, if the identity of the key is the correct one.
• the present invention aims at providing an electronic lock in which the current supply is guaranteed in a simple manner.
• the lock is provided with a manually operable electric generator connected to an energy storage device adapted to supply the electronic circuits with the required current.
• the electric generator is operable by means of a handle for actuating the lock.
• Fig. 1 is a block diagram of an electronic lock according to the invention
• Fig. 2 is a highly diagrammatic side view of an embodiment of an electric generator in a lock according to the invention.
• the electronic lock illustrated in Fig. 1 comprises in known manner a lock member 1 which may be mounted in.
• the lock member 1 comprise a lock mechanism 3 which may be of any known construc ⁇ tion whatsoever, and also a lock electronic system 4.
• the key member 2 contains information which identifies the key member 2 and can be transmitted, in some known manner to electronic circuits provided in the lock electronic system 4 to be determined thereby as the correct informa ⁇ tion for opening the lock. In such cases, the lock mecha ⁇ nism 3 is actuated or released by the lock electronic system 4.
• the lock electronic system 4 is supplied with curren via lines 5 from a storage battery 6 which can be charged by means of a manually operable electric generator 7 via lines 8.
• the electric generator 7 may be equipped with a permanent magnet rotor 10 having alternating magnetic poles around its -periphery and an iron yoke 11 on which a coil 12 is wound.
• the coil 12 is connected to the storage battery 6 via a rectifier 13.
• the rotor 10 can be rotated clockwise by means of a push bar 15 which is guided between pins 14 and is ar ⁇ ticulated with a handle 16.
• a push bar 15 which is guided between pins 14 and is ar ⁇ ticulated with a handle 16.
• the push bar is displaced towards the rotor 10, and a spring 17 articulated with the push bar15 will be compressed.
• a cam surface 18 on the push bar causes such a rotation o the rotor 10 and the end of the spring 17 engaging a notc provided in the periphery of the rotor that the energy stored in the spring 15 by the compression thereof will b released and converted into a rotational movement of the rotor 10.
• an alternating voltage is induced in the coil 12 and, after rectificatio in the rectifier 13, charges the storage battery 6.
• the handle 16 preferably is the one normally provide for manually actuating the lock mechanism 3 of the lock member.
• the electric generator and the manual operation thereof can be accomplished in many other ways than that described above; for example, ' the generator may be a piezoelectric generator. Those skilled in the art will also realise that any other energy storage device, such as a capacitor, may be substituted for the storage battery 6.
