Description

The invention relates to a device for securing roller shutters and roller shutters, which are formed from one consisting of numerous, interconnected blind roller shutter blinds, which is arranged with at least one suspension wound in at least one recess of a shaft, wherein the suspension of articulated interconnected pontics and the shaft-facing end member of the suspension has a hand-operable rotative actuator for releasably securing the device to the shaft.

Such a device is for example from the EP 2 589 742 B1 the applicant known. This known device basically has the advantage that with her in a very simple manner, in particular with little effort, a reliable connection of the shutter securing the shaft is made possible. Also, the dismantling is just as easy to reach. In addition, this solution has manufacturing advantages, since the basic version according to the invention can be easily adapted to different waves and their recess characterized in that the actuating arms are exchanged with the molded-on locking hooks.

Regardless, however, the object of the invention is to simplify the structure of the known device for securing roller shutters and shutters of the applicant still further, so while maintaining the basic advantages, the production costs are significantly reduced.

The solution of the problem arises from the features of the following claim 1. It reads:

Device for securing roller shutters and roller shutters, which are formed from one consisting of numerous, interconnected blind roller shutter blinds, which is arranged with at least one suspension wound in at least one recess of a shaft, wherein the suspension consists of articulated interconnected pontics and the Shaft-facing end member of the suspension has a handbetätigbares, rotary actuator for releasably securing the device to the shaft, characterized in that the rotary actuator is provided facing the shaft with an eccentric protruding into a recess of the shaft projection by the rotational movement of the actuating element there is a translational movement of the end member and arranged thereon, also projecting into the recesses of the shaft and extending in the same direction locking hook.

The main advantage of the solution according to the invention is that the rotary actuator causing the translational movement is very simple and inexpensive to produce and moreover, the end member can be reliably mounted on the shaft only by a quarter turn of the rotary actuator.

In an advantageous embodiment of the invention, the projection arranged eccentrically on the rotary actuator to the shaft additionally has a locking hook, so that the end member is fastened to the shaft not only with two locking hooks but with three locking hooks.

In principle, the locking hooks can extend parallel or transverse to the longitudinal axis of the shaft. In the first case, the rotary actuator is designed so that by a quarter turn a translational movement in the longitudinal direction of the shaft is caused and in the second case a translational movement transverse to the longitudinal axis of the shaft.

Advantageously, in a further embodiment, the end member and the actuating element may be formed as a plastic injection molded part. This results in a further significant reduction in manufacturing costs. In this context, it is also possible that the locking hooks are integrally arranged cohesively on the end member.

However, it is also conceivable that the locking hooks are formed of metal and attached to the end member. Although this is less cost, but then this arrangement has a greater stability.

Finally, the rotary actuator is provided with a projection for hand or tool operation, which can be configured differently. For example, the embodiment with an actuating slot, which is actuated by means of a coin or a screwdriver, possible.

In the drawings, a device for securing the shutters and rolling doors to a shaft 11 is generally designated by the reference numeral 10.

The device 10 (s. Fig. 1 ) is used to attach a roller shutter, not shown, by means of some intermediate members 12 and an end member 13 on the shaft eleventh

The intermediate members 12 and the end member 13 are hinged together. While the roller shutter armor facing intermediate member 12 is laterally, positively pushed onto the last to the shaft 11 facing roller shutter profile, which provided for attachment to the shaft 11 end member 13 has a special releasable fastening means 14, the recesses 15 of the shaft 11 engages behind.

In the Fig. 2 the end member 13 is shown enlarged. In the middle of the end member 13 is in a recess 16 is a substantially round rotatives actuating element 17 is arranged. The rotary actuator 17 is - like the Fig. 7 and 8th point - provided by the shaft 11 pioneering with an actuating plate 18 on which a projection 19 with an actuating slot 20 is present. On the rear side of the actuating plate 18, a protrusion 21 is formed eccentrically to the shaft 11, which in turn is provided with a locking hook 22 facing the shaft 11.

Finally, the actuating plate 18 of the rotary actuator 17 has on its periphery two recesses 23 which define the rotational movement of the rotary actuator 17 in the end member 13.

Like in the Fig. 2 recognizable, the circular recess 16 in the end member 13 of the shaft 11 pioneering a projection 24 and approximately opposite a recess 25 in which a spring tab 26 is arranged, which projects slightly into the recess 16.

When mounting the rotary actuator 17 in the end member 13, the edge of the actuator plate 18 engages behind the small projection 24 on the one hand and on the other hand engages the rotary actuator 17 in the region of the spring clip 26 in a rotatable end position within the end member 13 a.

On both sides of the rotary actuator 17, the end member 13 at the outer edges each have a window-like opening 27, wherein the window-like opening 27 facing the shaft 11 opposite to the underside of the end member 13 respectively a locking hook 28 is formed, the hooks are in the same direction in the x direction extend. Between the window-like openings 27 and the rotary actuating element 17, a depression 29 with a bore 30 is finally arranged in each case, which open the possibility, in principle, also the To arrange device 10 by means of simple fastening means on the shaft 11.

In the Fig. 3 can be seen the situation in which the device 10 is arranged unlocked on the shaft 11, where the rear view is shown. The essential feature of this illustration is that the locking hooks 28, which are formed on the end member 13 and the locking hook 22 while the recess 15 of the shaft 11 pass through, but not the recess 15 of the shaft 11 engage behind, so that still no locking state is reached.

In the Fig. 4 Finally, the locking state of the device 10 in the plan view of the end member 13 can be seen. When comparing with the Fig. 2 It can be seen that the rotary actuator 17 has been moved clockwise by a quarter turn until the projection 19 rests on the actuator plate 18 on the one hand to the small projection 24 and on the other hand to the spring clip 26. As a result of this rotational movement, a translational movement of the end member 13 in the x-direction is caused due to the projection 21 arranged eccentrically on the actuating plate 18, because the eccentric projection 21 is pressed in the x-direction during rotation by the contact with the boundary edge of the recess 15. By this movement, the locking hooks 28 and also the locking hook 22 engage behind the wall of the shaft 11, whereby a locking of the end member 13 on the shaft 11 takes place.

The locking state, ie the engagement of the wall of the shaft 11 by the locking hooks 22, 28, can be seen on the one hand in the Fig. 5 and on the other also in the sectional view according to Fig. 6 ,
