Universal fly screen with pleated edge

Abstract

Insect screen for windows, characterized in that the screen is springily pressed into the window reveal and fills it.

Description

Background of the invention

[0001] Protection against pests, particularly in Europe against mosquitoes and blowflies, and in southern countries against mosquitoes and tsetse flies, among others, is important because of their nuisance and the associated health risks.

[0002] Fly screens on windows and entrance doors provide constructive protection. State of the art

[0003] However, installing such grilles is often complex, requires an additional, precisely fitted frame, and obstructs access. Therefore, they are often installed only seasonally and temporarily. Given this, the effort required to achieve a tight seal is generally too high.

[0004] DE202014100027U1 and EP2481877A2 describe a fly screen for tilt windows, which is accommodated in the frame like a bellows when the window is closed from a rest position and, in an active position, closes a gap between a frame and a sash frame when the window is tilted about a tilt axis.

[0005] US patent application No. 2006 / 0108074 A1, published on May 25, 2006, discloses a fly screen having a pleated blind that is attached to a sash at a first end and to a frame member at a second end, such that the pleated blind is extended in the open position of the window and folded upon itself in the closed position of the window. Object of the invention

[0006] It is therefore an object of the invention to create a fly screen that can be installed in windows without a frame and yet is still mosquito-proof, if necessary only temporarily. Solution

[0007] The inventive step towards a solution is to dispense with custom-made frames for fly screens and instead to fit such screens with bellows-like edge zones that are inserted into the window reveals under tension, whereby the edge areas can also be covered with foam for sealing. Execution based on the figures

[0008] How Fig. 1, the grid material (1) is shaped like a bellows at the edges (2); preferably pressed in molds in this way.

[0009] The edges of the grid material (3) should (for better handling) either be overmolded with plastic or reinforced with a U-shaped clamping profile made of foam.

[0010] A mesh made of plastic or coated metal wire with a wire diameter of approximately 0.2 mm is recommended, with larger areas divided by stabilizing pressed-in beads. The forms can be constructed relatively simply from sanded molded plywood or hardwood slats; a certain rounding of the folds occurs automatically due to the resilience of the mesh material under moderate pressure.
