From the ball handle 2 attached to the outside of the door, the switch rod 17 can be operated with the key 20 can be rotated. With further reference to FIG. 4 and additionally FIG. 4, the lock corresponds to FIG Invention with devices for an additional extension of the bolt 9> that is, provided a safety latch step.

These devices consist of a plate-shaped Slide piece one 27 »with which the bolt 9 is firmly connected by the screws 28.

The slide piece 27 is provided with a rectangular slot 29, the length of which between the end walls 29a and 29b the sum of the extension steps of the bolt 9 and the normal extension length determined by the spring 11 of the bolt corresponds.

The slide piece 27 is arranged over a further plate-shaped slide 30, which is connected to a rectangular Slit 31 is provided, the length of which between the end walls 31a and 31b is substantially equal to that is determined by the spring 11 normal step of the latch 9. The slide piece 30 is with the slide 10 firmly connected, in which the ends of the already discussed levers 8 and 8a engage.

The slide piece 30 is also with another additional slot 32 provided, the inside a projection 33, as a result of which two single

609885/0402

Sections 3k and 35 are created, the function of which will be explained later.

In a third guide slot 36 in the second slide piece 30, the fixed pin 37 engages, which is arranged overhung on the wall 14a in order to serve as a guide for the linear sliding movement of said slide piece in the manner described below. On the plate-shaped slide piece one 27, a frame 38 is fastened, which is mounted pivotably on the pin 39 which is overhung on the slide piece 27. This frame with the function of a pawl is provided with a projection 40 which is bent in the direction of the slide piece 30 below, and this projection normally rests on the shoulder 41 of the slide piece 27 and engages in the notches 3h and 35 of the during the corresponding actuation Slide piece two 30 a.

A spring 42 is between the fixed pin 43 seated on the slide piece 27 and a nose 44 on the frame 38 so tensioned that it is pressed in the direction in which the projection 40 rests on the shoulder 41. A shaped slot 45 is provided in the frame with the slots 29 and 31 covers. Inside in slot 45 sits a projection 46 through which two stops 46a and 46b arise, in which the fixed pin 47 is functional intervenes, which is cantilevered on the box wall i4tL and which is through all slots 29,31 and 45 -

609885/0402

The end 45a of the slot 45 also forms a stop, which is perpendicular to the direction of movement of the bolt, which also includes the end face 31b of the slot 31 .

A cam profile 48 is also provided on the frame 38 and is recessed on its outer circumference. This cam profile is designed in the form of two substantially symmetrical side arms 48a and 48b. The cam profile 48 rests on the free end 49 of a cam 50 which is rotatably mounted on the pin 37, which also passes through the guide slot 36 of the slide piece two 30.

The end 49 of the cam 50 simultaneously engages in a cutout 5I ^{on the} slide piece one 27 and lies under the cam profile 48 of the swivel frame 38. The other end 52 of the cam 50 is provided with a longitudinal slot 53 into which the pin 54 protrudes on one Plate-shaped slide 55 is firmly seated, in which a cutout 56 is also incorporated, which is connected as a backdrop with the pin 57 which is attached to the component 21 already described, which is shrunk onto the shift rod 17. The slot 58 in the carriage 55 is used to guide the straight sliding

movement of this carriage provided by the bolt 25 on which the cranked lever 24 is pivotably mounted is. The box wall 14b is used to close the lock case 14, to which it is attached by means of conventional fastening screws not described here. The lock described in the previous text works in the following way:

The extension of the bolt 9 Ü ^m the usual through the FederTJbestimmte route has already been previously described, both in the form of triggering by the push button 6 as well as on the Schaltstangeffmittels actuation of the rotary handle 18 or from the outside with the key 20th

The safety locking step can be carried out from the inside as well as from the outside simply by actuating the switch rod 17 or with the twist grip 18 or the key 20.

If we assume that the lock is in the position shown in FIG by partially turning the shift rod 17 counterclockwise, With a view to FIG. 5, the carriage 55 through entry of the pin 57 into the cutout 56 in the with Shifted direction indicated by arrow F1. This displacement causes an angular movement of the cam 50 in the Triggered counterclockwise, the end of which 49 by pressure

609885/0402

on the side surface 48a of the cam profile 48 the frame 38 lifts. This makes the projection 46, which was previously on the fixed pin 47 on the box wall side 46a, released by the pin 47. At the same time will by raising the frame 38, the extension 40 is lifted out of the incision 35 of the slide piece 30. By a further angular movement of the cam 50, the slide piece one 27 and thus the bolt 9 with it a relative displacement with respect to the slide piece two 30 arranged below it. The postponement results from the engagement of the end of the cam 50 in the incision 5I of the slide piece 27 (Fig. 6).

After completion of the displacement of the slide piece and execution of the safety step of the bolt 9 by exiting the lock case 14 accordingly, the frame 38 is turned clockwise by the spring 42 moved, whereby the projection 46 rests against the fixed pin 47 inside the frame on the box wall 46b and the Approach 40 engages in the incision 34 of the second slide. In this position (Fig. 7) can by a possible actuation of the push button 6 on the ball handle on the inside of the door does not shift the bolt come about because the fixed pin 47 both the slide piece 27 by means of the frame 38 and the second Slider piece 30 by means of the frame 38 and after

609885/0402

rear curved extension 40 locks.

If the lock is to be unlocked, the shift rod 17 is in the opposite direction, that is, in a clockwise direction by means of the rotary handle 18 on the inside of the door or with the key 20 from the outside of the door to open so that a partial rotation of the shift rod is carried out.

This rotation causes the carriage 55 to move in the opposite direction moved to arrow F1, the pivot cam 50 in a guided opposite angular movement and the frame raised again, whereby the projection 46 by the fixed Pin 47 is blocked.

Thus, through the end 49 of the cam 50, the slide Eins 27 are moved until it is in the starting position, with the bolt 9 by the length of the bolt step is guided inside. In this position, the approach 40 comes again with the incision 35 of the slide two 30 (Fig. 5) into engagement, whereby this slide together is moved further with the slide 27, on which the bolt 9 via the levers 8 and 8a on the slide 10 is attached, or by actuating the shift rod 17, which engages in the cranked lever 24, which removes the force of the spring 11 on the stop 13 of the carriage 10 pushes.

With the device built according to this invention there is the advantage that a lock with push-button
