Definitions
- the invention relates to an electrical or electronic lock, in particular a cylinder lock, with a generator containing at least one coil for generating electrical energy using a key to be inserted into the lock and with an electromagnetic locking member with a Locking bolt.
- electrical or electronic locks can be supplied with energy in any way.
- proposals have also become known in which the energy required when a key is inserted is generated by mediating the key. In this way, additional electrical installations can be avoided to ensure the energy supply.
- DE-OS 3 819 954 describes, for example, a locking device with an address memory. It is a system that is to be used as an access control system, with a comparison of a key code with a code stored in a lock memory.
- the key coding here has an address code to which at least one byte of the memory is assigned. This byte can have two states. If the key is inserted in a reading device, the corresponding address is called and the byte is read. If it assumes the first state, the key is granted access, in the second the access is blocked.
- a programming card is required here, which must be inserted in the reading slot in front of the keys to be programmed.
- a magnetic key arrangement is also known from DE-OS 3 514 149, the magnetic key being used in addition to the usual permanent magnetic coding areas which are provided by a magnetic key.
- field sensor can be read one after the other, additionally has permanent magnetic clock areas which serve to control the reading process of the coding areas.
- a reading device is proposed in which serial scanning is possible with relatively simple sensors, the clock control meaning that only sensible information is passed on to an evaluation circuit.
- the clock areas are therefore arranged opposite the code areas so that the magnetic field sensor that scans the code areas is located at the instant of the signal exactly above the magnetic field maximum of a code area.
- DE-OS 4 201 936 describes a magnetic card lock.
- the magnetic card To open the lock, the magnetic card must be inserted into a slide and pushed against a spring until the locking mechanism is actuated. Since the slide is held in position by tumblers consisting of permanent magnets which are connected to a housing by means of springs, these tumblers must first be pushed back. This is done by inserting the magnetic card, which must be equipped with the same permanent magnets as the tumblers, with the magnetic repulsive forces between the card and the latch becoming effective, causing the unlocking. If the card is removed from the slider, the spring will assume the closed position again.
- an electromagnetically unlockable locking pin must absorb relatively high mechanical forces, and a relatively large amount of electrical energy is required in order to move such stable locking pins safely from a locking position into an unlocking position. Especially if
- the present invention therefore aims to further develop an electrical or electronic lock of the type mentioned at the outset in order to achieve secure locking and unlocking with the smallest possible dimensions, at the same time that for such secure locking or unlocking required energy should be generated directly in the castle 30 in a simple manner.
- the training according to the invention essentially consists in the magnetic displacement force for the locking bolt of the or the coils of the. Generator is generated. While in known devices using the coils of the generator electrical energy is generated, the inventive design same coils, which serve to generate energy, also used for the generation of the electromagnetic field, which generates the displacement force for the locking bolt or locking pin. With such a design, particularly small dimensions with high mechanical stability are guaranteed.
- the double use of the coils of the generator for magnetic unlocking makes it possible to create a safe and mechanically sufficiently stable construction even with very little space.
- the design is such that the locking bolt is guided in a metallic, magnetically conductive guide part, which can be magnetically connected to the yoke carrying a generator coil.
- a metallic, magnetically conductive guide part which can be magnetically connected to the yoke carrying a generator coil.
- the design is advantageously made such that the magnetic connection of the guide part guiding the locking bolt to a part carrying a generator coil is made by bridging a gap by inserting a partial region of a key containing magnetic or soft iron.
- a linear generator in which, in the axial direction of a key, a plurality of magnetic partial areas or soft iron-containing partial areas are set in operative connection with a yoke passing through the generator coils can, of course, when using magnetic partial areas in the key, the yoke parts passing through the generator coils can be made of soft iron.
- the design can be such that the partial areas consisting of the key or the soft iron parts of the key penetrated gap is bounded by pole pieces.
- the magnetic flux should be able to flow over the yoke that guides the locking bolt, so that either using partial areas of the key containing soft iron, the direction of magnetization must be reversed in order to force a flux over the locking bolt.
- the direction of magnetization must be reversed in order to force a flux over the locking bolt.
- the foremost sub-area of the key can be made soft-magnetic, whereas all other sub-areas that become effective for the generation of electrical energy can be formed by magnets, which are formed in a preceding gap between the ends of a piece of soft-iron parts
- the design is such that two yoke parts are provided which are offset in the axial direction of the lock and each carry at least one generator coil, and that the locking bolt is in the axial direction between the two yoke parts.
- the yoke parts carrying the generator coils have ends in a common plane, which can be bridged by magnetic partial areas of the key while reducing the existing gap.
- the training is preferably such that the yoke part leading the locking bolt in a plane following in the insertion direction with the interposition of a gap to the yoke parts carrying the generator coils
- the desired magnetic flux for releasing the interlocking - *, - lung bolt is advantageously achieved in that two Section ⁇ areas of a key in the axial direction seen magnetically with different Magneti ⁇ istscardi and / or as Soft iron partial areas are formed and are arranged at a distance from one another which, when the key is fully inserted, corresponds to the spacing of the planes and is aligned with the above-mentioned yoke parts, due to the mechanisms explained above either using a soft iron part or using a magnetic area With reversed polarity, the yoke that guides the unlocking bolt can be coupled to the generator coils when the key is fully inserted.
- FIG. 1 shows a side view of a key for use in an electrical or electronic lock according to the invention
- 2 shows a schematic section through an electrical or electronic lock according to the present invention with the key inserted
- FIG. 3 in an enlarged and perspective illustration, partially an electrical or electronic lock according to the invention.
- an arithmetic logic unit is generally connected both to a communication unit and to a memory and an unlocking circuit.
- a corresponding power supply must be provided for the entire circuit, which in the present case is made possible by converting mechanical kinetic energy into electrical energy by arranging a generator system in the area of the lock.
- a key 1 has magnetized, permanently magnetic areas 2.
- soft magnetic areas can be provided on the key 1 instead of the permanent magnetic areas 2. Accordingly, at least one permanent magnet is to be provided in the cylinder 3, the magnetic circuit indicated by the field lines 5 again being closed when the key 1 with the soft magnetic regions is inserted and a flux change being generated in the windings of the generator coil.
- the last permanent magnet of the key has an inverse polarity to the other permanent magnets 2 arranged on the key.
- this permanent magnet can be replaced by a piece of soft iron.
- the two coils 8 are not only used to generate energy, but also serve to actuate the locking bolt 10.
- the guide part 13 carrying the locking bolt 10 is hereby
