DE386782C - Mortise key lock with ring disc-shaped tumblers - Google Patents

Description

The lock according to the additional patent 380475 comes with a lock nut, Tumbler disks acting on a locking member for use by one-punch of a key can be transferred to the frequent position that one on the key attached guide acts on stops on the tumbler disks and this accordingly adjusted.

In order to be able to use this lock in particular for safes and to design it as a combination lock, a multi-part key is used according to the invention, so that the tumbler discs first have to be adjusted against each other in individual separate groups in order to reach the open position ? X \ .

An example embodiment of the invention is shown in the drawing. ao namely shows

Fig. Ι and 2 a longitudinal or cross section through the lock nut,

Fig. 3 shows a longitudinal section through the associated multi-part key. «5 Fig. 4 to 6 show the individual parts of the key.

Figs. 7 and 8 are end views associated with Figs. 4 to 6 in different positions these parts.

Fig. 9 shows a development of the circumference of the key parts when they are in position Take Fig. 7 and the guide grooves in these parts merge into one another.

Fig. 10 shows this development when the key parts are in the position shown in Fig. 8 and the guide grooves in the individual key parts are offset from one another. Fig. Ir and 12 show the two setting keys belonging to the master key in diagrammatic form Opinion.

Fig. 13 shows another embodiment of the master key in longitudinal section and Fig. 14 the corresponding front view. Fig. 15 is a view of the rear part of the key.

Fig. 16 shows the associated setting key on average.

The lock consists of a number of disks 1 of the same size, which are loosely inserted in a lock nut 3 provided with a longitudinal slot 2. The lock nut 3 is rotatably mounted in a fixed housing 4. Tn the longitudinal slot 2 of the locking nut 3 is a stepped locking member S, which, resting on the circumference of the tumbler washers 1, enters with the opposite flanks into recesses 6 & of the fixed housing 4. In this case, the locking member 5 is in the locked position and the lock nut 3 cannot be rotated. In order to remove the blocking, the recesses 7 arranged on the circumference of the tumbler disks 1 must be aligned so that they lie one behind the other in front of the locking member 5 and this can move inward.

In order to be able to adjust the individual tumbler disks r in groups, a multi-part key used, which in the embodiment shown consists of three parts 8, 8 'and 8 ", which are nested in one another, whereby they have a cylindrical Form shaft which is inserted into the central recess 9 of tumbler 1 can be. The individual parts are provided with guides 12, 12 'and 12 "on the circumference, which in a certain position of the parts to each other a coherent guide result (see Fig. 9). The position is secured by the fact that the Heads 13, 13 'and 13 "are provided with grooves 14 are, with an adjusting key 15 pushed onto the heads (Fig. 11) by means of a Longitudinal rib 16 engages in grooves 14. In In this position, the key can be inserted into the recesses 9 of the tumbler disks that adjust according to the shape of the guide.

If you now twist the individual parts of the key against each other, so will twisted the tumbler disks that interact with these key parts. Through this the previously connected guides 12, 12 'and 12 "are separated from one another (see Fig. 10). The arranged in the heads

th grooves 14 assume the position shown in Fig. 8, for example. This location can be secured by a second setting key 17, which is distributed around the circumference S resilient stops 18, 18 'and 18 "are provided which engage in the grooves 14 of the respective heads. Suffice it to set sliding over the key and turning it.

Only in this position of the guides are the full tumbler disks sitting on the key 1 provided with the cutout 7 for the locking member 5. The lock can therefore are only opened when the individual groups of the guard locking disc! in this situation are brought. You therefore always have two separate settings for opening the lock of the master key, which is activated by means of two separate setting keys 15 and 17 can be made. Will the master key of a person and the or If the key is given to another person, the lock can only be used in the presence both can be opened or closed, which is known to be often required for safes will.

Instead of the setting key, the circumference of the heads 13, 13 'and 13 "can also be written with letters or numbers, so that the key can only be used in a certain position introduced and brought about the open position in another specific position can.

In Fig. 13 to 15 is another embodiment of the key. Here are the individual parts 8, 8 'and 8 "on one Pin 20 lined up, which is screwed into the foremost part 8 "and against rotation is secured. The middle part 8 'is with a pushed onto the pin 20, within the rear part. 8 mounted sleeve 21 coupled in that the ends of these parts by means of Approaches 22 overlap. All parts are held by the head 23 of the pin 20. This head is provided with a longitudinal groove 24- Furthermore, the head 13 forms the rear Key part 8 has a control surface 25 and 26 which expires in a cutting edge, the Flanks sloping from the cutting edge to both sides (Fig. 15). In the same way the sleeve 21 is also extended into a control surface 26.

Used to set a master key

an adjusting key 27 which is pushed over the head 24, a rib 28 attached to the adjusting key entering the longitudinal groove 24. A helical control surface 29 is attached to the setting key on one side, which presses against the two control surfaces 25 and 26 when the setting key is pushed over and thereby adjusts the parts in the end position (Fig. 14b) so that a continuous. Leadership (see Fig. 9) is created. Now the key can be inserted into the locking device. If this is done, the other end of the adjusting key 27 is used. This end is against each with two at an arbitrary angle 'other staggered guiding-surfaces 25' and is provided 26 ', with the guiding-surfaces 25 and: cooperate 26th When attached manipulated '■ therefore, the key parts are key ^overall: adjusted against each other, so that, for example, take the one illustrated in Figure 10 position.. In this position, the projection 19 of the key can enter a corresponding recess in the lock nut 3, and the lock can now be adjusted. Of course, the setting key can also be made in two parts here. It is particularly noteworthy that the inserted key cannot be removed when the lock is in the open position.
