Description

[0001] The invention relates to an insect screen device according to claim 1, which is intended for windows and doors.

[0002] Insect screens for windows and doors are available in a wide variety of designs. Besides permanently mounted fly screens, there are several solutions for temporarily attaching insect screens to windows and doors. Temporary installation is particularly recommended in temperate climates where the presence of bothersome insects is seasonal, meaning insect protection is only needed during certain times of the year. Since permanently installed fly screens are visually unappealing, there is a significant demand for removable insect screens in these climates.

[0003] There are therefore already numerous solutions for temporarily installing insect screens on windows or doors. For example, adhesive tape can be used to attach hook-and-loop fasteners to the window frame, to which a mesh screen is then attached using corresponding hook-and-loop fasteners. The disadvantage of this method is that the mesh can be easily damaged when attaching and removing it, and it is difficult to achieve a tight and secure fit of the insect screen on the window.

[0004] German patent application DE 101 26 006 A1 discloses a clip-on frame designed to be inserted into a window frame. This frame consists of an outer frame that is placed in front of the window frame from the outside and has elements that engage with the window frame to secure the outer clip-on frame to the window frame. To facilitate easy insertion of the clip-on frame into the window frame, some of the engagement elements are spring-loaded, allowing them to slide parallel to the clip-on frame towards the inside of the frame and then automatically return to the outside of the clip-on frame under the influence of the spring force.

[0005] Such window frames can be conveniently placed in front of an existing window, but are relatively expensive due to the complicated mechanics and the elaborate outer frame.

[0006] DE 299 08 620 U1 discloses a profile suitable for clamping an insect screen or mesh in a complementary groove in the window frame, so that the insect screen or mesh is clamped to the window frame by the interaction of the profile and the groove. However, this requires that the window frame used has a corresponding groove that fits the profile, making this embodiment rather unsuitable for retrofitting existing windows. Furthermore, attaching the insect screen or mesh is difficult, as the mesh must be pulled taut while the profile is simultaneously clamped into the groove.

[0007] A framed mesh screen, suitable as a rigid screen element, particularly for insect protection in motor vehicles, is known from DE 100 12 166 A1. The rigid mesh screen can be positively connected to a frame component, which in turn can be mounted on the vehicle using conventional edge-mounted fasteners. Due to its rigidity, this technology is only conditionally suitable for retrofitting to a window or door frame; more importantly, it complicates seasonal installation and removal, as well as space-saving storage.

[0008] DE 87 07 952 U1 relates to a frame with a fabric or film covering that can be inserted into window frames in a snap-in and self-tensioning manner. For insertion, the frame is made of a springy material, the tension of which secures the frame in the snap-in position. Larger frames can be designed to be disassembled and reassembled, but space-saving storage and transport involve considerable assembly effort.

[0009] Therefore, there is a need to provide an insect screen device that can be manufactured inexpensively and attached to the window easily and securely.

[0010] This problem is solved with an insect screen device according to claim 1. Advantageous further developments are set out in the dependent claims.

[0011] An insect screen device according to the invention has a self-supporting frame. In an insect screen device according to the present invention, this frame is relatively thin, so that it can be inserted into the frame of a modern thermal insulation window from the inside and is located in the space between the outer window frame and the frame of the actual window. The frame engages in the groove located on the outside of the window frame. Since conventional thermal insulation glazing has a double seal, i.e.,With an outer seal located on the outer frame and an inner seal located on the movable window frame, which is pressed against the inside of the window frame when the window is closed, the insect screen device according to the invention can be arranged between the movable part of the window frame and the fixed outer frame without causing any problems with the window's sealing. Since there is always a gap between the movable frame and the outer window frame, it is possible to open and close the window as usual, even with the insect screen device in place.

[0012] The frame of the insect screen is now covered with a mesh or gauze that reliably prevents insects such as mosquitoes, beetles, butterflies, moths, etc. from passing through the window, while at the same time not significantly hindering the supply of fresh air to the interior.

[0013] To enable the insect screen according to the invention to be easily installed in a window frame, the frame is made of a flexible, elastically bendable material suitable for folding or rolling the insect screen into a space-saving, reduced-size state. The insect screen does not need to be disassembled; it can be bent into this space-saving state solely due to the elastic flexibility of the frame. In this folded state, the insect screen can be easily inserted into the window frame. After release, the insect screen automatically unfolds due to its inherent elastic restoring forces, thus filling the window frame with the mesh or gauze.

[0014] In principle, a wide variety of materials are suitable as material for the frame of the insect screen device.

[0015] The frame of the insect screen can be made from a single piece or assembled from straight and / or curved rods and corner components, depending on requirements. These components preferably have a thickness of at least 1 and at most 10 millimeters; a frame thickness in the range of 3 to 7 millimeters is particularly advantageous, with approximately 4 millimeters representing a good compromise between strength and a thin design.

[0016] Further advantages, features, combinations of features, or properties of the present invention will become clearer with reference to an exemplary embodiment and the following drawings. These show: Fig. 1: an insect screen device according to the invention comprising a frame and a gauze Fig. 2: the insect screen device according to the invention placed in a window frame Fig. 3: the insertion of an insect screen device according to the invention into a window frame Fig. 4: the groove in front of the outer edge of a modern window frame

[0017] Fig. Figure 1 shows an insect screen 1 according to the invention, comprising a frame 2 in which a gauze 3 is clamped. The frame of the insect screen 1 according to the invention is made of a material such as glass fiber or carbon fiber composite, or elastic plastic, manufactured by injection molding. The frame can also be made of a different material than shown in Figure 1. Fig. In the embodiment shown in 1, the gauze or mesh is manufactured in one piece. During injection molding, the gauze or mesh is embedded in the frame during the injection molding process, enabling particularly cost-effective production.

[0018] In Fig. Figure 2 shows an insect screen device according to the invention installed in a window outer frame. The frame 2 rests against the inside 4 of the window outer frame 5 and against the rear of the outer edge 6 of the window outer frame. Since locking elements 7 for the movable window are provided on the inside of the window outer frame, the insect screen device according to the invention is reliably secured against being shifted inwards. In addition, a frictional force can be applied to the inside of the window outer frame by means of the frame, thus further reinforcing the secure retention of the insect screen device according to the invention. This is facilitated by the fact that modern thermal insulation windows either slope downwards towards the outside in the frame or have a groove 9 in front of the outer edge 6 in which the insect screen device can engage (see Figure 2). Fig. 4).

[0019] As in Fig. As shown in Figure 3, the insect screen according to the invention can be easily removed from the outer window frame by elastically bending the lower frame part 8 when the insect screen is not needed, for example in winter. Due to the appropriate design of the elasticity of the frame parts of the insect screen, they can be folded together, thus enabling space-saving storage when not in use.
