With the present roller shutter lock, the locking bolt is pulled up when the Shutters brought ready to close without, as in known arrangements ,, .wähnend the rough, in .he the, shutters pulled up is to be kept tensioned by means of a spring; , also securing the locking bolt not triggered by means of a special construction part. This is achieved

ίο Effect through an arrangement in which the locking bolt is pulled back by hand for the purpose of opening the roller shutter and the bolt by a fuse is held in this position, the fuse with one of the Lock protruding part in the latch of the roller shutter intended for the locking bolt intervenes. If the roller shutter is now • pulled up, it pushes the safety device back and triggers it, so that the locking bolt under the roller shutter immediately protrudes and itself can put in readiness for closing without a spring remaining tensioned for a long time. If, on the other hand, the roller shutter is lowered, then he pushes the locking bolt back, the immediately jumps forward again as soon as the rest is opposite.

The drawing illustrates an embodiment of the arrangement. Fig. 1 shows. a front view of the lock cuff. Fig. 2 and 3 show the lock arrangement with different positions of the locking bolt and the fuse. Fig. 4 to 7 show items. In a lock case b a through the opening of the cuff α stepping locking bolt h (Fig. 2 and 7) is stored, the front a latch h ¹ for engaging a securing part and rear an upward end or a suitable other surface A ² has been given, against .which a lever d (Fig. 2 and 5) with the end d ¹ lies down, for the purpose of being able to retract the locking bolt h. The nut; or the lever d sits on a rod c that protrudes from the inside of the window or door frame and there with a suitable handle, ζ. B. ο (Fig. 4) is equipped. The automatic advancement of the lever d into the position ¹ I (Fig. 2) takes place by means of the spring n, whereas the locking bar h is advanced by means of a two-legged lever kk ¹ swinging around i , the leg k of which is under the influence of the spring m . In addition to the Nußhebel d (Fig. 2) there is a to e oscillating and when changing cross through the Stulpöffnung securing part f h for the locking bolt, which part f with appropriate surface f ¹ (Fig. 6) is provided for engaging the detent h ¹ (Fig. 3) of the locking bolt h, and there are also provided at f, behind the pivot point e (Fig. 6), locking surfaces f ² f ^s , against which the nut lever d can put when the securing part f exerts its effectiveness (Fig. 3), or when it is in the rest position (Fig. 2). In addition, the securing part f also has an appropriately resilient extension or arm g (FIGS. 2, 3 and 6), which is partially located in the recess d ^{2 of} the nut lever d or above the end d ^{1 of} the latter.

The lock case b is on the side of the channel

Claims (1)

for the roller shutter embedded in the window or door frame. If a roller shutter, not shown, is now lowered, it pushes the locking bolt h back, which automatically protrudes again as soon as the opening provided for this purpose in the roller shutter side is opposite it. If, on the other hand, the roller shutter is to be pulled up, then first of all by means of a handle, e.g. B. O and rod c, the nut lever d, d ² and d ¹ rotated, whereby the nut lever d passes from position I (Fig. 2) to position II (Fig. 3) and the locking bolt h is withdrawn. During this movement of the lever d , the lever part d ¹ - lifts the arm g of the securing part f , which- . art that it tips over forward and stepping through the faceplate opening with the surface f ¹ (Fig. 6) in the detent h ¹ (Fig. 3) of the locking bolt and now holds it retracted. If you let go of the handle 0, then the spring η turns the nut lever d, d ² , d ¹ forward, and it rests against a locking surface f ^s (Fig. 6) of the locking part, so that this fuse in the occupied Location is held. In FIG. 3, when the handle 0 is released , the lever d, which automatically retreats into the starting position, is indicated with dotted lines. Since the locking bolt h is now withdrawn and the stepping safety part f is held, z. B. the roller shutter belt can now be grasped with both hands and the store pulled up, the store bumping against the securing part f and bringing it from the position of FIG. 3 to that of FIG can automatically put in readiness for closing. The handles for operating the shutter lock can be briefly summarized as follows: First move: lower the load. Effect: pushing back and protruding the Lock bolt to lock. Second handle: movement of the handle. Effect: pulling back the locking bolt and its backup. Third hand movement: pulling up the drawer. Effect: Automatic release of the fuse and automatic setting of the locking bolt in readiness for locking. . Pate ν τ-An SPRU c η: Automatically acting roller shutter lock with locking parts which are housed in a lock arranged on the side of the roller shutter, characterized in that the bolt (h) , which is always held in the closed position under the action of a spring-controlled lever, is first pushed back by the lowered roller shutter and then jumps into the gap between the doors When pulling up the roller shutter, however, it is moved back by hand with the help of a lever (d) and secured by a latch (f) falling into the gap , whereupon the latch (f) is released again when the roller shutter is raised and the bolt (h) is in its Closed position is automatically moved back. 1 sheet of drawings.
