Definitions

  • the invention relates to a device for covering a window or door opening, namely an insect protection roller grille device for insect-proof, air-permeable covering a window or door opening, with a flexible, preferably mesh-like insect protection grille, or a device for shading or darkening a room with a flexible Shading or darkening element, which is guided with its two lateral edge sections in lateral guide rails attached to the outside of the opening and can be wound onto a winding shaft rotatably mounted above the opening, which can be rotated about its axis and locked in the respective rotational position.
  • the invention particularly relates to an insect screen rolling grille device in which a weight bar with a weight so large is attached to the lower end of the insect screen that the insect screen can unwind automatically after the winding shaft is released.
  • the invention is also applicable to so-called spring roller blinds, in which the winding shaft is connected to a torsion spring which is tensioned when unwinding the insect screen or the shading element, so that it can be wound up again by spring force.
  • the invention is described below as an insect protection device.
  • the present invention is based on the object of further developing a device of the type mentioned at the outset that, in the unwound position, it considerably impedes unauthorized entry through the window or door opening covered by it.
  • the device according to the invention contains a clamping device for releasably fastening the lateral edge sections of the cover element. It is preferably provided that the clamping device clamps the edge sections of the cover element within their lateral guide rails in the locking position.
  • the device according to the invention offers a high degree of protection against so-called break-ins, which are triggered by a potential burglar noticing an open window.
  • the jamming of the lateral edge sections of the insect screen also has the advantage that the insect screen does not tear out of the side guide rails even in strong wind gusts, for example when a thunderstorm is approaching sen, which would not only result in insects entering the building, but could also damage the gauze.
  • the clamping device can be provided both in the case of a spring roller blind and also in the case of a roller grille device with an automatically unwinding insect screen.
  • the flexible mesh fabric is stretched taut in the vertical direction by the weight rail, so that all-round bracing takes place together with the locking of the lateral edge sections.
  • the clamping device can be expanded between a release position in which the edge sections of the insect protection gauze can be freely moved along the guide rail and the locking position.
  • the clamping device has at least one hose in each guide rail, the cross-sectional dimensions of which can be increased by supplying compressed air such that it presses the associated edge section of the insect screen against a stop.
  • the stop is expediently a strip which, like the hose, can consist of rubber.
  • the hose and the strip extend substantially over the entire length of the respective guide rail.
  • the rubber hose is expediently attached, for example glued, to one long side of the guide rail, while the bar is attached to the opposite long side of the guide rail in such a way that the hose and bar lie directly opposite one another and absorb the insect protection gauze between them.
  • the guide rail advantageously has a substantially rectangular shape with a slot, which preferably has a width of approximately 1.3 mm and which is delimited by two parallel webs.
  • the distance between the hose in the relaxed state and the bar should be at least as wide as the slot in the guide rail.
  • the expandable hoses arranged in the two guide rails are closed at their upper end and connected to a compressed air source at their lower end. It is within the scope of the invention that a common compressed air source is provided for both hoses, which then supplies the compressed air into the two hoses via a branching line.
  • the top ends of the hoses can e.g. be plugged or otherwise, e.g. Gluing, welding, etc. must be closed.
  • the compressed air source is a pneumatic pressure pump that is operated by hand.
  • This pressure pump can function like a bellows and be as small as a so-called dimmer, for example, since only a very small volume of compressed air has to be pumped into the hoses in order to expand them so far that they clamp the insect screen.
  • the pneumatic pressure pump is expediently connected to the expandable hose via a check valve, which e.g. can be opened by finger pressure so that the compressed air can escape from the hose back into the pressure pump.
  • a valve elbow is expediently inserted through the Window stick and the guide rail and inserted into the hose end. This elbow is connected to the pressure pump on the inside of the window frame.
  • a metallic mesh film or perforated film can be used as the insect screen, which is connected to an alarm system.
  • FIG. 1 shows a generally customary roller shutter box 1, in which a winding shaft 2 of large diameter for a roller shutter armor 3 is arranged. Below the winding shaft 2, there is sufficient space in the conventional roller shutter box 1 for arranging a further winding shaft 4 for an insect screen 5 which is made of gauze and is therefore very thin.
  • the winding shaft 4 has a very small diameter because the gauze 5 is wound up tightly.
  • the two winding shafts are designed and supported in a conventional manner, which is why a description of further details can be omitted.
  • FIG. 2 shows a window which is equipped with the arrangement according to FIG. 1.
  • a belt 6 is provided, which is wound up in the usual way on a pulling roller, not shown, which is connected to the winding shaft 2.
  • a belt 7 is arranged to actuate the insect screen 5, which is wound up in a corresponding manner on a pulling roller, also not shown, which is connected to the winding shaft 4.
  • Fig. 2 it can be seen that the insect screen 5 is arranged between the roller shutter 3 and the window, so that the side guide rails of the insect screen 5 are attached between the guide rails for the roller shutter 3 and the window frame, for which purpose generally only one space in of the order of about 10 mm is available.
  • FIG 3 shows a horizontal section through a lateral guide rail 8 which has a slot 9 for the entry of an end region of a guide rail 11 projecting beyond a weight bar 10 and the associated edge area of the gauze 5.
  • the slot 9 is delimited by two parallel webs 12.
  • the weight bar 10 ends at a slight distance in front of the guide rail 8, while the guide bar 11 extends almost to the inner wall 13 of the guide rail 8.
  • the weight bar 10 is surrounded by a plastic cover bar 11 ', on the underside of which there is a bristle strip 14 (FIG. 4).
  • a side flange 15 is formed on the guide rail 8 for the insect screen, which engages under a conventional guide rail 16 for the roller shutter curtain 3.
  • the U-shaped guide rail 16 and the flange 15 are fastened by means of screws 17.
  • a rubber strip 18 and an expandable hose 19 are fastened within the guide rail 8. These two components are glued to the inner surfaces of the long sides 20 of the guide rail 8. In the pressure-free state of the hose 19 shown in FIG. 3, the insect screen 5 can be moved freely between the rubber strip 18 and the hose 19 together with the guide bar 11 attached to the end section thereof, so that the insect screen 5 can be wound up and unwound.
  • Fig. 4 the clamping state of the insect screen 5 is indicated, in which the hose 19 is expanded by the supply of compressed air so that it presses the gauze 5 firmly against the rubber strip 18 so that the insect screen 5 can not be pushed up. In addition, it is ensured that the edge sections of the insect screen cannot emerge from the guide rails 8 even when very large wind forces occur.
  • Fig. 5 shows purely schematically the connection of a hose 19 to a pneumatic pump 24 which is arranged on the inner side of the window.
  • a lower valve elbow 21 is guided through the window frame 22 and the guide rail 8 and inserted into the lower hose opening (at 23).
  • the pneumatic pressure pump 24 has a diameter of a few centimeters, so that it does not have a visual effect. It is operated by thumb pressure, i.e. pressed inward when compressed air is to be introduced into the hose 19 in order to clamp the gauze 5.
  • thumb pressure i.e. pressed inward when compressed air is to be introduced into the hose 19 in order to clamp the gauze 5.
  • the air is released - again by finger pressure - via the pneumatic pressure pump or the lock is released.
  • a gas or compressed air container to expand the hoses instead of a pneumatic pump.
  • This can be a small gas or compressed air cartridge that does not have to be permanently attached, but can be attached to the non-return valve of the hose system if necessary and then taken back up (and otherwise stored for reuse).
  • the one-way valve can protrude from the window frame.
  • the actuation of the clamping device is further simplified, and the actuating device takes up practically no space on the window frame.
  • a brush strip 25 is fastened, the elastic bristles of which lie against the gauze in such a way that the bristles of the brush strip 25 sweep over the surface of the gauze 5 during the downward and upward movement and thereby detach adhering foreign particles such as dust etc.
  • the brush strip 25 is an insect barrier by reliably preventing insects that have entered the roller shutter box from entering the interior of the room behind the gauze 5 through the window or door opening.
  • the brush strip 25 closes a considerable cross-sectional portion of the gap leading into the roller shutter box, which represents a cold bridge.
  • Fig. 6 also shows that the brush strip 25 is attached to the front end edge of a window cross member 26, which is flush with the front end face of the adjoining window frame 27.
  • the bristles of the brush strip 25 protrude so far that the gauze 5 is slightly bulged in the contact area.
  • the purely schematic Fig. 7 shows that the brush strip 25 extends over the full width of the gauze 5, so that the latter is cleaned over the entire surface of the brush strip 25.
  • the insect screen Since the insect screen is guided past the brush strip with each upward and downward movement, the insect screen is constantly freed of foreign particles automatically, so that this process is not associated with any effort.
  • the gauze therefore remains clean over a long period of use and retains its air and light permeability.
  • the brush strip 25 expediently has a height (seen in the direction of movement of the insect screen) of approximately 1 to 2 cm, it being preferred that the bristles of the brush strip have a length of approximately 5-15 mm.
  • the bristles are preferably made of a soft, elastic plastic, which means that the brush strip practically does not make it difficult to unwind and wind up the insect screen.
  • the insect protection gauze can unwind automatically if it is provided with a weight bar, as is the case with the insect protection rolling grille device known from German patent 39 36 343, to which reference is expressly made here.
  • the brush strip can also rest on the outside of the insect screen, such a brush strip also being able to be arranged in addition to an internal brush strip.
  • the brush strip located on the outside of the insect screen can, for example, be attached to a carrier arranged there in the roller shutter box near the winding shaft.
  • the brush strip provided according to the invention not only achieves the effect that the insect screen is constantly kept automatically clean. Another advantage of the brush strip is that a brush strip attached in the region of the inner outlet edge of the roller shutter box, which abuts the insect screen, reliably prevents in insects that have entered the roller shutter box can penetrate from there into the window or door opening by passing through the space between the inner outlet edge of the roller shutter box and the insect screen. This is made impossible by a brush strip arranged there.
  • the brush strip provided according to the invention closes a cold bridge to the inside of the roller shutter box, which is present in conventional insect protection roller grille devices, which likewise means a considerable improvement over the prior art.
