Description

The invention relates to an insect screen rolling grille

for covering building openings that open. one -of a torsion spring in the winding position tensioned winding roll can be wound up and unwound in one Box-like housing supported in the area of an edge of the building opening is, from which the rolling grille can be withdrawn against the action of the torsion spring, and with an end strip attached to the pull-off end of the rolling grille, which is attached to the winding shaft Unrolled rolling grille in the area of the edge on which the box-like housing is stored, opposite edge of the building opening can be fixed.

In DE-OS 30 23 903 such an insect screen rolling grille is shown and described in detail.

There is the box-like housing on the upper cross member of a building opening, z. B. a window frame attached. When the rolling grille is unrolled, the The end strip is hooked into the lower cross member of the window frame, with the rolling grille is loaded and tensioned by the torsion spring of the winding shaft.

According to DE-OS 30 23 903 the problem is an insect screen rolling grille with regard to the sealing on the lateral and vertical spars one in building openings To improve the frame used, with the easiest possible assembly possible should be solved in that the housing has an actuatable locking device have actuatable tensioners for the winding shaft and the trailing edge, which are located in Support the clamping position resiliently on an associated bracket.

It turns out, however, that the problem of sealing on all sides goes far can be solved more easily if the invention ensures that the box-like casing as a closed housing with one provided on one of the upper edges, the Width of the rolling grille corresponding to the rolling grille outlet slot and one on one the lower edges provided water drainage slot and formed on the lower edge the building opening is attached to the trailing edge means for pulling off of the rolling grille upwards and for final fixation at the upper edge of the building opening are provided.

With such an arrangement remains because of the support of the force the torsion spring by pulling out the rolling grille against gravity tense and lies down without difficulty on the side rails of the building opening without any special clamping devices in the housing and / or on the trailing edge requirement.

This makes the arrangement much simpler and therefore also cheaper.

In particular, however, can such a rolling grille with special Combine the advantage with a roller shutter, because the ones provided on the end strip Devices for pulling off the rolling grille upwards and for final fixing at the top Edge of the building opening can consist of connecting elements that connect to the end strip connected to the movable roller shutter in front of the building opening in any detachable manner can be. With a roller shutter made of interconnected plastic or Light metal slats is already an attachment of the box-like, which Winding shaft receiving housing at the top of the building opening no longer or only possible with difficulty because the two corresponding housings are mutually exclusive would disturb. Here it is therefore of particular advantage that according to the invention the the winding shaft receiving box-like housing at the lower edge of the building opening is attached. It is then easy to remove the end strip of the roller shutter if necessary with the end bar of the insect protection To connect the rolling grille releasably and when the roller shutter is raised, it progresses from the opening to the building to be removed at the top, and at the same time the building opening through the insect screen rolling grille to close insect-proof. The guide rails of the roller shutter are also in place available as guides for the rolling grille.

With the rolling grille according to the invention, the risk is also eliminated that to be attached to the end strip of the roller shutter and in the known rolling grilles pull-down device, e.g. one provided with a holding button at the end Pull cord, no longer rushing upwards if you accidentally release it Can put around the winding shaft and thus no longer accessible to the operator is. In such cases, an attempt is often made, without closing the window, to release the pulling element again by climbing onto the window parapet, which is to Hazardous situations, sometimes even leading to serious accidents.

Winding up, for example, an operating cord on the winding shaft is not possible with the insect screen rolling grille according to the invention. Will be such Unintentional release of the operating cord, then it also snaps up, however, the button at the end catches itself in the guide elements and falls due to its own weight back within reach of the user.

Since in the known rolling grille to pull down the same basically the window must be opened is through until the window opening is closed the rolling grille of the ingress of insects possible. The influx of insects increases in the evening hours when the lights are normally on in the rooms, unless it will turn off all lights before opening the window. In this case however, it is difficult to find the rolling grille handling, since only in the rarest Cases a light switch is provided immediately next to a window.

If, on the other hand, the rolling grille according to the invention is combined with a roller shutter, then the roller shutter is lowered until all of its slat openings are closed whereupon the window for hooking the rolling grille to the end strip of the roller shutter is opened and is closed again immediately after hooking, so that not which are formed between the individual slats of the roller shutter when it is raised Open slots for insects to fly in. Is the roller shutter then in his upper end position, the window can be opened again. The appropriate handling can be done with full room lighting.

The insect screen rolling grille according to the invention can also at any time can be retrofitted without difficulty. This is especially true for Building openings that can be closed with shutters, as there is attachment to the lower one Building opening spar does not cause any difficulties and also with door openings can be made so that the box-like housing does not interfere.

Here, too, are the existing guide rails for the roller shutter can be used as guide rails for the rolling grille.

The box-like housing can be advantageous in the simplest way build up of two angular profile strips set against each other, which are so spaced are arranged that the rolling grille outlet slot at one of the upper edges and the water drainage slot on one of the lower edges, preferably on the diagonal one opposite edge arises. The angle profile strips are expediently by means of two side panels kept at a distance, which are also the bearings for the Winding have a wave, in the simplest case a corresponding one Sdckbohrung on the inside of the respective side part.

This water drainage slot can be covered by a mesh grid, if it is not chosen so narrow that insects can enter through it Slot into the inside of the box-like housing and from there through the rolling grille outlet slot inside the building is prevented.

Rainwater, which practically never penetrates the rolling grille anyway, runs down on it and can enter the box-like housing through the rolling grille outlet slot enter. It does not stay there, however, because this housing can # through the Leave the water outlet slot unhindered again.

The trailing edge is then particularly expedient as an upwardly open one U-profile formed when the rolling grilles are used on a building opening should, which can be closed by a roller shutter. The profile width is then so too choose that the lower end strip of the roller shutter can sit in this U-profile. This is useful on the side of the web facing away from the U-profile legs with pointing downwards, fitting into the rolling grille outlet slot and between the rolling grille edge receiving and it is provided there fixing legs.

The pins on the end strip of the roller shutter can be simple, through appropriate Plastic pins fitted with a head on one side are bores in this trailing edge that are fixed with the help of a Seeger ring ~ over which a part is then added protrudes over which the attached to the end strip of the insect screen rolling grille Hooks can be placed. This hook is useful with a side curve provided to facilitate its operation.

The drawing shows in Fig. 1 a section through an inventive trained insect screen rolling grille in its arrangement on the lower spar, for example a window opening; and in Fig. 2 a partial plan view of the area the fastening hook on the end strip of the insect screen rolling grille and the protruding one Pin on the end strip of the roller shutter.

With 1 in Fig. 1, the window reveal-denotes, over which a Drainage plate 2 extends. 3 denotes the lower spar of a window frame the generally denoted by 4 te box-like housing connected in any way is.

This box-like housing A consists of two angle profiles 5 and 6, which are placed together so that at 7 a rolling grille outlet slot and at 8 a water drainage slot is created. The water drainage slot is in the reproduced Embodiment closed by a grid 9.

Inside this box-shaped housing 4 is located the Winding shaft 10 on which the rolling grille 11 is wound and which with the help of a The torsion spring not shown is pre-tensioned in the winding direction of the rolling grille is. The rolling grille 11 is attached to the winding shaft 10 at 12. The other end the rolling grille 11 sits between two legs 13 and 14, which on the web 15 of a U-profile are attached. The attachment of this end of the rolling grille can be done in any way Wise, but should be insect repellent in any case.

In the illustrated embodiment, it sits in the U-profile 15 the lower slat 16 of a roller shutter, of which only one more slat 17 can be seen. This roller shutter can move upwards in the direction of the double arrow A. and moved below, which can be done by i1and, but also by motor. the lower lamella 16 has a bore 18 through which a provided with a head 19 Pin 20 is inserted, which is fixed with the aid of a Seeger ring 21. About the protruding part 22 lies a hook 23 which rests on the pin 24 on the U-profile 15 is attached.

In Fig. 2, the U-profile 15 is partially visible in side view. One can also see the hook 23 mounted on the pin 24, which has a bend 25 which is also shown in FIG. This hook reaches over the end 22 of the pin 20 inserted through the lower lamella 16.

It is thus possible to use the insect screen rolling grille with the To connect shutters, it is particularly advantageous that when the connection is established the insect screen rolling grille at the same time as the roller shutter is raised or lowered is extended or retracted.

You can also see that the insect screen rolling grille can be retrofitted at any time can be attached to the spar 3.

The box-like housing 4 also has at the end of the angle profiles 5, 6 each have a side part 26 which fix the angle profiles and also each have the bearing point for the winding shaft on the inside, which is the simplest Case consists of a blind hole receiving the respective end of the winding shaft.
