Sliding bolt with releasable locking pawl rotatably arranged on the bolt

for doors, windows, etc.

Patented in the German Empire on April 19, 1921.

The invention relates! on with trigger! but only the one on the bolt

bar, rotatably arranged on the bolt 'pin rotatable latch, but that for loading

Pawl-equipped sliding bolts for doors, the bolt does not act as a force

Window or the like and consists in the fact that the Rie-: the latch, but directly on the Rie-

ge! is not under the action of fire itself, come to the conclusion! is exercised. A

Another feature of the invention ¹ is that the above-mentioned spring force is exerted on the pawl of the actual sliding bolt by springs, which at the same time act on other bolts moving perpendicular to the sliding bolt ¹ .

The invention is shown in the drawing in an exemplary embodiment in Fig. ι to 3 in 'three different positions of the bolt shown.

Fig. Ι shows the latch in the open position. The sliding bolt 1 is on the base plate 3 ″ in a manner known per se by two brackets 6 guided. It carries a pawl 7 which can be rotated about a pin 8 on it. At the The pawl 7 engages a push rod 9 at 10, in the manner described in more detail below is under spring force.

The movement of the bolt r is done with the help of a key which is in the slot 20; of the lock 21 is introduced, and acts in a manner known per se either directly with its beard or through the intermediary of a rotating piece 22 against a shoulder 23 on the side of the bolt 1. If the latch is 1 in; the final position, the first time the key is turned, the bolt is brought into the position shown in Fig. 1. . In a second rotation, the situation of fig 2 is first obtained and then, as soon as the rotating part has passed the projection 23 22, 9 of the bolt under the pressure of the rod back into ^the: brought final position of Fig. 3. ;

In the locked open position according to Fig. 1 '; engages the nose 13 of the pawl 7 behind the: ratchet 14, which in turn on the Base plate 3 is attached. If the sliding bolt 1 is now to be triggered, the Using the key, push the bolt back into the position shown in Fig. 2. Here will; through which against a stop 16 the bent end 15 of the pawl 7 lying on the base plate so around its pivot pin 8 pivoted that if now the bolt ι is released by the key, the nose 13 freely pass the ratchet 14 under the action of the pull rod 9 can. During this movement, the pawl 7 rests against the guide surface 17.

Before the bolt has fully reached its Schfaßlage shown in Fig. 3, has the pawl 7 experience a rotation that of those in the transition from the position of Fig. Ι is directed in the opposite direction to the position of Fig. 2. The opening happens in the other way around.

With the sliding bolt 1, four further bolts 24 are inevitably connected in the embodiment shown. These bolts are used, for example, to secure the top and bottom edges of a door. The bolts 24 carry transverse pins 25, between which and the lower parts 26 of the bolt guides ¹ 27 compression springs 28 are switched on. The auxiliary bars 24 are connected to rotary disks 30 and 31 with the aid of traction means, for example double wires 29, which in turn are coupled by means of traction means 32. The push rod 9 acting on the pawl 7 engages the turntable 30.

In the position of the main bolt 1 according to Fig. 1 the auxiliary bolt 24, as well as the main bolt, are completely withdrawn. The feathers 28 are therefore tensioned and act by means of the traction means 29 and the rotating disks 30 and 31 in such a way on the rod 9 and the pawl 7 that a spring pressure is exerted on the latter will. During the movement of the main bolt ι to the position of Fig. 2, the Auxiliary bolt 24 withdrawn a little further than is actually necessary for the opening is. After snapping off the key 22, both the main bolt 1 and the auxiliary bolt are 24 freely subjected to the action of the springs 28, so that all latches are in the final position snap in ·.

Claims (2)

Patent Claims: 1. With releasable, rotatable on the bolt arranged locking pawl provided sliding bolt for doors, windows or the like, characterized in that the rotatable pawl (7) is under spring action, while the force to open the bolt (1) acts on it itself. 2. A bolt according to claim 1, characterized in that the spring action exerted on the pawl (7) is generated by compression springs (28) which tends to press ^{additional auxiliary bolts (24) into their Schkißlage to 1, which are inevitably connected to the main bolt (1)} are. 1 sheet of drawings.
