Description

The present invention relates to a closure device for a wall opening with several strip-shaped elements, the strip-like elements on both ends in guide devices each having two guides are stored so that they are in a first state with their long sides lie together and a flat Form cover for the wall opening and in a second State are stacked side by side in parallel, the Guided tours in the area essentially within the Wall opening lying section parallel parallel run side by side.

Such closure devices are generally known and are used as covers for wall openings of all kinds used. For example, DE 44 40 693 A1 shows one Locking device used as a blind or as a sectional door can be used. There are several stable elements in the first, i.e. lowered state vertically stand on each other, in the second, i.e. pulled up condition stacked almost horizontally one above the other. The stable Elements are over two on each side of the wall opening Guide pin supported in two guide rails each, the two guide rails on one side in the lower Area of the wall opening a narrow distance and in the upper Area of the wall opening a greater distance from each other to have. Due to the narrow spacing of the guide rails in the The elements are in the lower area of the wall opening first, i.e. lowered state perpendicular to each other. The larger distance of the guide rails in the upper area the wall opening, however, causes the elements in second, i.e. in the raised state almost horizontally Layer are stacked on top of each other. Such a stack however requires a large installation volume.

Furthermore, from DE 26 23 359 B2 is a closure device known for wall openings, several of the same type Slats on both sides of the wall opening in one Guide rail are guided, in the lowered state arranged one above the other form a closed surface. In open state, the slats are in the way of a Slats arranged deflection device above a Wall opening stackable side by side. Through the Deflecting the lamellae on both sides Disengaged guide rails. So the slats are not more stored in guide rails, which is why they go back and forth can wiggle and hit each other. As a result the risk of damaging the surfaces of the slats become. Furthermore, the slats have on both sides an axis parallel to the longitudinal axis of each lamella rotatably supported roller, with adjacent slats are connected to each other by means of joints, which at one Slat pivotable about the axis of the rollers and on the other slat parallel to the longitudinal axis of the guide rails are attached. However, such a construction is very complex and therefore expensive.

EP-A-0 425 480 describes a closure device for a wall opening with several strip-shaped wall elements, in the area of the wall opening in a vertical extending guide rail are slidably mounted. Guide devices for the wall elements are also shown in an area outside the wall opening, that the wall elements are substantially parallel to the Wall elements in the area of the wall opening in an open Condition of the closure device can be stacked. For this purpose, the wall elements are suspended in an articulated chain and can be activated by actuating the link chain in the open or closed state of the Closure device can be moved.

The object of the present invention is a Closure device of the type mentioned above to further develop that with safe guidance of the cover elements the stacking process is improved and also a inexpensive construction is made possible.

This object is achieved by the features of Claim 1 solved.

According to the invention, the guides go in the area of a end lying outside the section of the wall opening each in an arc in a spaced-apart, parallel arrangement over, which is essentially perpendicular on the course of leadership in the area of the section Wall opening extends. This results in the known arrangement of the guides the great advantage that the strip-shaped elements not in an almost horizontal position are stacked on top of each other, but essentially parallel to the guides in the area of the section of the Wall opening, can be stacked next to each other to save space can. In addition, the strip-like elements connected to each other in such a way that they are stacked come to lie at a distance from each other. In contrast to the known stacking arrangements in which the surfaces of the individual elements are close together and thus the There is a risk of scratching, which prevents stacking of the elements according to the invention at a distance from one another such damage. Here are the strip-shaped elements to each other via rocker arms hinged. This creates a secure connection between adjacent strip-shaped elements made over the also the distance between the long sides of the strip-shaped elements in the first state is adjustable. In contrast, are conventional closure devices the elements usually only with each other via rigid joints connected, the no further variable setting of the Allow distance between adjacent elements. Farther are the individual elements in the invention Construction articulated with each other via the rocker arms connected so that the rocker arm pivots and Linking the strip-shaped elements from the first state enable in the second state via an arch.

The invention is based on the idea of a special guidance and connection of the individual cover elements to create a simple, inexpensive construction and at the same time the stacking of the cover elements in the area improve outside a wall opening.

So are the strip-shaped elements of the invention Closure device advantageously in the area of their End faces at a first and a second point stored in the two guides, the first point being the spaced apart arrangement of the guides is closer than the second point, and - based on the arc of the Guided tours - is the first point in external leadership and the second point is stored in the inner guide. Through this Arrangement has the great advantage that the strip-shaped elements when moving from the first to the second state are safely guided on both faces, so that jamming of the elements prevents and a smooth operation is guaranteed.

The guide devices are advantageously as Running rails formed. Such an embodiment represents a very inexpensive variant of the invention, since commercially available components are used can who are not specifically for building a Closure device according to the invention are made have to. At the same time it is ensured that the strip-shaped elements when moving through the Running rails are precisely guided.

The rocker arms are advantageously in one piece trained and have at their upper and / or lower end one incision each. About this incision the effective length and thus the distance between neighboring ones strip-shaped elements can be varied.

Has proven to be particularly advantageous in this context proven to form the rocker arm in two parts and to connect telescopically. Through this Embodiment ensures that the effective length of the rocker arm can be varied. That way the distance between adjacent strip-shaped elements according to the respective specifications.

Has proven to be particularly advantageous in this context proved that the rocker arm can withstand the forces exerted by Moving the strip-shaped elements from the first to the second state and vice versa, each from one strip-shaped element on an adjacent one transferred strip-shaped element. This will make the load not directly as with known devices transferred along the long sides of the elements, but picked up by the rocker arms.

According to a further embodiment of the invention strip-shaped elements in their first state outside their outer guide arranged, taking a short Holder in the outer guide and over a long holder in of the inner leadership. Such Embodiment allows the strip-shaped elements in the second state at a distance from each other in the area outside of the section of the wall opening. The long holder acts as a spacer between neighboring ones Elements and prevents the individual elements in the stacked state as well as one with it associated damage to the surfaces of the elements Scratch. Furthermore, the arrangement of the strip-shaped elements in their first state outside the outer guide that the guides are covered from the outside are. So the guides are not visible from the outside, creating a unified appearance of the Closure device arises.

After a further embodiment of the invention strip-shaped elements in the second state at an angle tilted between 10 and 30 ° to those in the area of the section guides lying in the wall opening are stacked. Such Tilting position ensures a particularly space-saving Arrangement of the strip-shaped elements in the second state, because the elements come to lie flat. In contrast, are basically only such from the prior art Stacking arrangements are known which have a greater installation height require.

According to a further advantageous embodiment of the Invention can be the farthest from the arcuate course of the Guides removed strip-like element on one Be attached to the rope arrangement, over which Locking device can be moved. So through simplest design means of the drive for moving of the strip-like elements from the first to the second State and vice versa. This in turn keeps the Manufacturing costs of the closure device low.

In this context, the rope arrangement can be further training of the invention to be manually operated. A such a closure device contributes to both the cost of manufacturing and later To keep maintenance very low, since no complex Drive device is required.

However, it is optional after further training in Invention possible, the rope arrangement with a to provide electromotive drive. Although these are Embodiment based on higher manufacturing costs, however the user is thereby given the opportunity, too to choose a higher ease of use.

Run according to a further advantageous embodiment the guides in the area of essentially within the Wall opening lying section vertically. The are strip-shaped elements in terms of their Longitudinal alignment horizontally and in the area of your lower end via a roller in the inner Guide and in the area of its upper end on a roller slidably mounted in the outer guide. hereby can the strip-shaped elements in the area outside the Wall opening, for example, saves space behind a lintel be stacked. At the same time, the free space is above a wall opening used sensibly.

With a wall opening in the form of a gate or a door A room is the interior of the two guides Inside of the room and the outer guide of the outside of the room facing. If the room falls in the area of the gate or. Has the top of the door, the curve of the Guides, at least in part, behind this fall to be ordered. In any case, it is different from each other spaced, parallel arrangement of the two guides behind attached to the lintel so that the stripe-shaped Elements in their second state behind the lintel are stacked, are no longer visible from the outside and the full passage height of the gate or door opening guaranteed is.
