Mustard lock with key

The invention relates to a tumbler lock with a key, in which - when the key is stuck in the keyhole - The fixed longitudinal center plane of the keyhole and the longitudinal center plane that can be rotated with the key cover the key bit.

With these known tumbler locks, the swings completely into the lock - i.e. out of the enclosure through the Keyhole in the lock plate out - keys pushed into the lock when the door is knocked or when other shocks, as a result of its one-sided weight given by the key bit, into a position, the subsequent strong slamming or movement of the door to slide the key out of the Keyhole leads.

The invention is based on the object of a tumbler lock to be designed with key in such a way that undesired sliding of the key out of the keyhole is prevented.

To solve the problem, it is proposed to determine the center of gravity of the key in the lock to be arranged in such a way that the key bit is in one position when the key is inserted into the lock holds, in which the longitudinal median planes of the keyhole and key bit are in the axis of the key shaft a cut. In such an arrangement of the longitudinal center planes the key bit is pivoted far enough to allow the To protrude beyond the contour of the keyhole, with which at least parts of the key bit provided with the keyhole Reach behind the lock plate and slide the key out of the lock - without prior position correction is excluded »

In a preferred embodiment, the longitudinal center plane of the keyhole are vertical. The center of gravity can be unilaterally through the longitudinal center plane of the key bit occurring accumulation of material are arranged, with the key inserted swiveling the key bit out of the vertical results from vibrations.

Advantageously, the one-sided accumulation of material can take place in the area of the key handle, because then the Design of the key bit can remain unaffected. For this purpose, the in the longitudinal center plane of the key bit lying key handle can be bent, arched or reinforced on one side, so that in this regard previously existing symmetry is disturbed at least in a balanoic manner. In the first two cases this can originally be intended total weight remain unchanged.

In order to be able to apply the invention in a simple manner to already existing tumbler locks, or else,

to provide balanced keys in case of need to have, the accumulation of material can be caused by a one-sided weight that can be releasably attached to the key handle will. This weight can preferably be an attachable attachment, for example a Cap made of elastic material in particular, which has a slot for receiving the key handle and a metal disc, for example, resting flat on the key handle, with the contour of the handle.

The invention can also be used while maintaining the conventional Use tumble key when the keyhole is inclined slightly so that its Longitudinal median plane is inclined to the vertical. As mentioned at the beginning, it tends to be in a vertical position Key bit hiritergrip then after his release aas Lock plate with the keyhole on the invention Way.

The invention is explained in detail below, reference being made to the drawings. These show:

Pig. I made a cut through one in a keyhole stuck key bit of a key according to the invention with a relocated Center of gravity is provided;

Fig. 2 shows a section through the key according to Pig «1, the key completely in the Lock is pushed in and released;

Fig. 3 is an end view of the invention Key of a first embodiment;

Key of a further embodiment, and

Pig, 5, shows a key according to the invention 3 in a perspective illustration.

The sections in FIGS. 1 and 2 show a key bit a key 12 which, according to the invention, loads on one side of the longitudinal center plane 14 of the key bit 16 is. In Fig. 1, the key bit is in a keyhole 18, so it cannot go around the axis of the key shaft 20 can be twisted.

Fi ^. 2 shows the position of the fully in the lock 22 inserted key 12, for example v / ie that shown in Figs. 3 and 5 may be formed. Here one-sided accumulation of material attached to its handle 24 causes the key 12 to move into the position shown in FIG. 2 in the event of vibrations in the lock 22 twisted, with parts of the key bit the lock plate 26 reach behind with the keyhole 18. The key 12 can no longer get out of the keyhole, if not its longitudinal center plane 14 with the longitudinal center plane 28 of the keyhole 18 is aligned, which corresponds to the alignment of the key bar 16 shown in FIG corresponds to the keyhole 18.

In connection with the above explanations it can be clearly seen that when the longitudinal center plane 28. of the keyhole and so that this itself is genexgt to the vertical, the task on which the invention is based with a conventional one Buntbart key, the key bit of which is in Hibernation depends on the vertical, can be resolved. This can be seen in the drawing in FIG. 2 when the Key bit 16 is regarded as a keyhole and the keyhole 18 as a key bit.

such., conventional key 32, which with a cap 34 made of elastic plastic is provided, the key grip 30 and a flat against this Slice 36 overlaps and secures. The cap 34 is attached and can therefore be retrofitted to a Fit key 30. Like the disk 36, it can also have a hole if this appears appropriate and also in different colors - for the purpose of identifying certain keys. the Disk 36 forms an accumulation of material on one side of the key handle 32, similar to the ■ - based on the Fig. 5 - to the right of the dashed line marking the usual strength of the balanced key handle 38 lying accumulation of material 24 on the key 12 so that the disc 36 causes a shift in the center of gravity when the key is in a vertical position Keyhole is used.
