Robert Schumacher in Neviges, RhId. Safety lock with split pin tumblers. Patented in the German Empire on August 13, 1924.

The invention relates to safety locks with split pin tumblers, whose Locking pins are mounted in sliding guides, on which the acting as a displacer Slide along the pin parts as the bolt moves. Compared to known lock security devices of this type, the subject matter of the invention differs in that the displacer is directly in the lock bolt or key attacks lying on the bar intervene. By this arrangement, in which the key without the clutch with a rotating drum or other intermediate link to require the opening and closing movements as with simple locks Able to perform with his beard immediately, it is made possible to lock everyone Type, such as door, furniture, padlocks, safe locks, etc., with across the bolt or brackets insertable key without increasing their thickness dimensions as security locks.

The drawing illustrates a number of embodiments, which are different Explain the application forms of this safety arrangement.

Fig. Ι shows a door lock set up in this way after removing the lock cover.

Fig. 2 and 3 show sections along lines 2-2 and 3-3 of Fig. 1. ·

Fig. 4 illustrates, on an enlarged scale, the one used here Position of the displacement heads in the locking bolt.

Figs. 5 and 7 show the lock pin arrangements in use with padlocks. The castle covers are thought to have been removed.

Figs. 6 and 8 are cross-sections along the lines of Figs. 5 and 7.

Fig. 9 and 10 show in plan and section a provided with the new arrangement Safe lock bolt.

The locking part of the lock device, bolt a, bracket b, is guided between rails c , in which the locking pins d are mounted, while the displacement heads e, through which the locking pins are disengaged in a manner known per se, are mounted in the locking part and intervene with their heads in the key attacks of bolts or bars. In the designs according to Figs. 1 to 3, 5, 6 and 9, 10, the locking pins press their displacement heads from both sides into the key grips, so that double-bit keys are required to open the locks in question, but without increasing the bolt thickness or bit width multiple security against unauthorized opening is achieved. In the embodiment according to Fig. 1 to 3, the displacement heads are secured in the simplest way against falling out when the lock changes position, that they still partially engage in the transverse walls of the key attacks, while in Fig. 9 and 10 they are in the usual way by reducing their diameter are prevented from falling out.

By introducing a key bit designed in accordance with the displacement paths of the heads e , the locking pins are disengaged, as is known. By turning the key or by spring pressure, the bolt or bow can now be locked out of its locking position, whereby the displacement heads slide along the guides in the direction of the opening movement. You have to block this opening movement at any point by letting the locking pins engage in corresponding openings equipped with displacement heads e ' . These displacement heads e' have the same shape like the heads e, the lock can be unlocked with the same key; if they are designed differently, a second key with a corresponding beard shape is required. and closed position. In the versions according to Fig. 5, 6 and Fig. 9, 10 the bolt lock also takes place in an intermediate position, which must be released by a second key. It can be produced with simple means and with security against unauthorized opening a safe or safe lock, which in a known manner requires the cooperation of two people to open and close it, who each have a part of the Ver by the key in their possession - and have to effect the unlocking movement. If desired, the number of intermediate positions to be unlocked can easily be increased even further by inserting further displacement heads in the slide piece of the breechblock that slides along the firing pins.

Claims (4)
