Description

Locking mechanisms are preferably used in locks and/or locking cylinders. In the case of the latter in particular, a major challenge is to replace the locking cylinder in its traditional form with a standardized electronic locking cylinder with its own power supply. This means that the electronic locking cylinders currently on the market with their external power supply can be replaced by a much cheaper locking cylinder, although the basic requirement is to ensure the battery life or the life of other energy supplies over a long period of time.

The real difficult point in all electronic-mechanical systems is to convert the electronic energy into mechanical function with minimal energy consumption.

The electronic locking cylinders or electronic locking systems on the market today all have an electromagnet which , when supplied with electricity, activates a bolt mechanism which is used to release and lock the lock.

The same applicant has already described an electronic locking cylinder in which the actual opening and closing, ie the force required for this, is carried out by the user's hand or by means of their key. A new locking system was presented here in which the locking bolt was originally extended from a suitably shaped latch against spring pressure by turning the key, whereby in the "closed" position the locking bolt struck against a resistance.

The disadvantage of this application, however, was that under strong torques this resistance could be crushed or at least deformed, which impaired or destroyed the function of the locking cylinder and thus of the entire lock.

For this reason, a new patent application was made in which the actual locking bolt is buffered so that, via a locking bolt driving element mentioned here, even the greatest torque on the lock bolt cannot have a destructive effect on the actual locking bolt or on the resistance, which in turn means that the resistance, which is designed, for example, as an eccentric of a micromotor, can be correspondingly smaller in size and made from a material that is not normally suitable for absorbing high pressures.

Furthermore, since only one specific embodiment has been described in this patent specification, the application of a locking bolt can be designed in a variety of ways by means of a driving element with a buffer effect, the purpose of the invention is to generalize the concept.

The invention will now be explained in more detail with reference to device claims 1-11 with figures 1 and 2.

Figure 1 shows a schematic view of a possible locking system from the front, with the locking bolt (1) resting in the catch (9) of the lock bolt (11). This position is simultaneously secured by a spring element (7). The locking bolt (1) is extended by a bolt element (5), which rests in the catch (4) according to its shape on the lock bolt side and slides out of it by turning the lock bolt (11) according to its conical design.

The great advantage of the device, however, is that during this sliding movement, the locking bolt (1) moves downwards through the milled recess (14) of the lock bolt (11) via the connection (2,12) under spring load (3), whereby spring (3) is naturally stronger than spring (7). In the "closed" state, bolt portion (2) of the locking bolt removal element now rests on the eccentric (6) shown here, whereby even the strongest torques acting on the lock bolt (11) are buffered by the spring (3), so that on the one hand the locking via the locking bolt (1) is still guaranteed and on the other hand the eccentric (6) is not damaged by the spring force (3).

With the rotation of the eccentric (6) via the motor shaft (13) or the like shown schematically here, the locking bolt driving element (2, 12) finds a downward travel path and thus takes the locking bolt (1) with it, whereby the rotation of the lock bolt (11) into the "open" position of the locking cylinder (11) can be carried out.

In the embodiment shown, the corresponding locking or bolt elements are arranged so that they can move in their guides (8, 10). At the same time, the variant shown here makes it possible to minimize the load on the eccentric (6) so that the load on the motor is also kept to a minimum, which ensures that the power supply via battery guarantees the lock's functionality for a long period of time.

Figure 2 shows a schematic view of the locking bolt-lock bolt connection from the front. The locking bolt (1) is mounted (7) in the lock bolt (11) latch (9) and, through the recess (14), offers the lock bolt (1) the required travel path for the bolt (5) from its latch (4).
