Door lock with a bolt located outside the lock case and a push-piece that can be raised.

Patented in the German Empire on July 14, 1921.

It is known; for door locks by raising the inner one, independently of the outer one movable pusher to advance the sliding bolt of the lock, and it is also known to have one with the inner pusher

to unite the latch bolt located on the lock case, which is in the horizontal position of one pusher latches into a detent, but when moving the outer pusher on the Rast slides by. The door lock according to the

In contrast, the invention is characterized in that an inside on the lock case latch located when raising the inner handle latches into its latch and when Depress the inner pusher and the other pusher connected to the latch moved by means of a stop. Thus, in such a simple way, the independent Mobility of the two pushers in relation to ίο on the latch bolt and their coupling in relation to achieved on the latch, and such a simple lock is particularly useful for purposes Suitable where the usual sliding bolt is unnecessary, such as on toilet doors, bathroom cells and the like. To prevent unauthorized locking, for example by children, is a special one Embodiment provided, accordingly, the inner pusher in the outer pusher in ends a mandrel which allows the inner pusher to be pushed into the outer one by means of a Turn the key from the upright to the horizontal position and thereby unlock the door.

The drawing illustrates this latter embodiment in Fig. 1 in plan view, partially cut, in Fig. 2 in side view and in Fig. 3 in a cross section through the Lock case.

The lock has two door handles 1 and 2 stored in the lock case 15. The inside handle ι carries a mandrel 3 on which the hollow shaft 4 of the external handle 2 can be rotated is mounted, which moves the latch 11. With the pusher 1 is outside the lock case 15 a latch pawl 5 connected at right angles, which by pivoting up the Lever 1 latches into a latch hook 7 attached to the door post. The mandrel 3 carries Cams or grooves 8 (Fig. 1), by means of which the handle 1 and thus the latch of the handle side 2 is returned to the open position with the aid of a socket wrench 9 can be. The shaft 4 is outside the lock case 15 with a screw or pin on the shaft 4 attached ring 5, and this ring carries a behind the Latch pawl 6 engaging stop 10. This stop is when the is depressed The pawl 1 of the handle shaft 4 is also rotated, which by means of the nut 12 (Fig. 2) the snap bolt 11 withdraws. A cover rosette 13, which is used for the movements of the drop bolt 6 necessary lateral recesses is provided, holds the handle 1 against axial displacement. '

When the pawl I or 2 is depressed, the snap lock 11 becomes more normal Way pushed back; the pusher 1 is raised in the direction of the arrow in Fig. 2, where if the handle 2 remains in its horizontal position, the door is opened by means of the drop bolt 6 locked, and it can either by pivoting the pawl 1 back into the horizontal position or in the present embodiment also from the other side of the pawl by means of the be unlocked on the mandrel 3 to be plugged socket wrench 9. For example, at a slamming of the door 0. can the cover rosette 13 with a against the bolt 6 in its upright! position hinged locking lug 14 (Fig. 2).

By replacing the previous pushers with those according to the invention, existing ones can also be used Locks can be provided with the new fuse in the simplest way.
