PATENT OFFICE

CLASS 68: Locksmith.

In the present embodiment of the security lock according to patent no. 92857, the two tumbler groups according to patent no. 94064 are combined to form uniform plates. The innovation consists in the fact that the disc c , which becomes free and entrained after the classification of the first tumbler, can also be rotated further after the second classification of the tumbler plates - without endangering this order - and this further rotation can be used to directly reverse the lock bolt itself - resp. to advance.

The innovation is essential insofar as it enables the locking piece g with the two shafts g ¹ g ² to be omitted. Apart from the associated simplification of the lock, the aforementioned circumstance has the high practical value that it makes the function of the lock independent of minor disturbances, while the locking piece g, with its plurality of shafts and with its rectilinear displacement, enables an extremely precise adjustment of both the disc c as well as the tumbler plates if no functional disturbance is to occur. In the long run, however, such an accuracy can hardly be made possible due to the inevitable wear and tear of the guides in which the shafts g ^ g ² slide back and forth over time.

At the same time, the security of the lock does not even suffer with the present innovation the slightest inconvenience compared to the aforementioned, practically so sensitive device, because also with the lock executed according to the present innovation the shift of the lock bolt does not begin until the second guard locking device has been fully classified takes, and vice versa after the end of the return movement of the lock bolt into the closed position Both tumblers can also be brought back into disorder, thus double security is retained in all cases.

On the accompanying drawing is the new embodiment of the lock for illustration brought.

Fig. Ι and 2 show the same in front view in the closed position BEZW. according to classification the second guard locking.

Fig. 3 and 4 are sections along line yy (Fig. 2) and respectively. Line xx (Fig. 1). FIG. 5 shows the lock in a position corresponding to FIG. 1 with the tumbler plates removed. Figure 6 illustrates the latch.

The plate-shaped shaft g of the bolt is guided in a corresponding groove in the bottom of the lock case and has a cutout ^{g 2} . In the latter, a pin c ¹ seated on the disk c engages, so that sufficient rotation of the disk c to the right or respectively. left, a back or Forward movement of the bolt gg ¹ .

To now this bolt movement only after the completion of the classification of the second guard locking to let in and everybody

To avoid disturbance of the order, the slots / ² belonging to the second tumbler are here in the form of a circular arc. Arranged concentrically to the key pin, and in the lock case a pin ν is attached, on which the slots Γ ^{2 are set} in the second arrangement. The slots s ¹ belonging to the first tumbler are here extended to the rear over an arc of 90 ° so that after the second tumbler has been classified, further rotation of the tumblers and thus also of the locking disk is possible. During this last rotation, the locking disk c moves with its pin c ¹ the bolt gg ^l , which is guided in a straight line by means of the cutout g ³ on a rectangular box.

The protected by patent no. 94033 means on the Verschlufsscheibe c conachsial mounted drive plate ρ is here formed with screw-thread-like tapered to aufsen guide jaws ^ ³ for the key bit in the manner, it DAF in case of a rotation by the introduction of the key blade in the right Aniangsstellung is turned back.

The mode of operation of the security lock is as follows:

If one introduces the double-bit key in the locked position of the lock shown in FIG. 1 and turns it a quarter circle to the right into the dotted position, the slots s ^{1 are opened} on the locking pin s ^{by means of the bit part r 1} and the spring plates t classified. During the second quarter turn of the key, the locking disk c with the tumbler plates is now pushed through the disk p, the base disk 0 respectively guided by the curve plates dd ^1. whose pin p ^{1 was} taken.

With the arrival in the position shown in FIG. 2 position, the tumbler plates occur under the action of spring disks i ^1, the slots / ² DAF ^'2 are now arranged immediately ν on the pin, composed of beard Theiles r. The key with locking disk and tumblers can now be turned in the direction indicated by the line % -% drawn in FIGS. 2 and 5. During this last rotation of the locking disk beyond the second order position of the tumbler plates, the latter move with the slots Γ ² over the pin ν and the pin c ^{x of} the locking disk c takes the bolt gg ¹ into the exposed position in FIG. 5.

The castle is now in the open position. By turning the key back to its initial position, the locking mechanisms are actuated in the opposite way, ie first the bolt gg ^{1 is} pushed forward again and then the two tumblers are adjusted again one after the other.

It should also be mentioned that the cutout g \ in the bolt shaft is shaped in such a way that during the first quarter turn of the disk c until the second tumbler is included, the bolt cannot be carried along by the pin c ¹ .

Claims (1)

Patent claim: An embodiment of the lock according to Patent No. 92857 and No. 94064, in which the rotation of the disc (c) is made usable for the immediate movement of the lock bolt (gg ^l ) without impairing the double security, because the slots belonging to the first tumbler (S ¹ J extended beyond the quarter-circle arc and the slots (F ² J belonging to the second tumbler are arranged in a circular arc shape concentric to the axis of rotation of the disk (cj and, while the latter is idling, they are arranged on a pin (v) fixed in the lock case, whereupon As the disc c with the tumbler plates continues to rotate, the former moves the bolt by means of the pin (c ¹ ). 1 sheet of drawings.
