[0058] A fabric is arranged in the frame. The fabric serves as a window filling that fills the frame.

[0059] When the frame is assembled, the fabric extends between the inner and outer profiles of the frame.

[0060] The fabric is a textile sheet. Preferably, but not exclusively, the fabric comprises at least two thread systems that intersect at an angle when viewed from above.

[0061] The fabric has an elastic structure.

[0062] By way of example, but not exclusively, the fabric may be made of a material. It goes without saying that the fabric may also be made of another artificial or natural material.

[0063] The fabric has a continuous side edge. The side edge is designed as a border around the fabric. The border of the fabric can be an elastic hem. Of course, the side edge of the fabric can also be made of a different material.

[0064] The rubber hem anchors the fabric to the inner and outer profiles of the frame. To anchor the fabric to the frame, the rubber hem engages the inner and outer profiles of the frame. This integrates the fabric into the frame.

[0065] By anchoring the fabric border (rubber hem) in the inner and outer profile of the frame, the elastic fabric can be telescoped together with the frame to any predetermined circumference.

[0066] A fabric border is provided on the outer edge of the fabric. When the frame is assembled, the fabric border extends into the groove of the inner profile and the groove of the outer profile.

[0067] In the area of ​​the corner connector, the fabric border runs within the corner connector's receiving chamber. The receiving chamber can encompass an edge. clamping spring

[0068] The connecting element has at least one clamping spring.

[0069] The clamping spring can be secured by means of an anchor in the connecting element.

[0070] The clamping spring has a contact surface for engagement with the inner or outer profile. The clamping spring secures an inner and outer profile of the frame against each other.

[0071] In order to ensure that the clamping spring has a preload, a clamping spring bend is arranged in the recess of the connecting element.

[0072] The clamping spring exerts a clamping effect between an outer profile and an inner profile of the frame.

[0073] The clamping spring secures the frame using its inherent clamping action. The frame can be of any size.

[0074] Thanks to the clamping spring, the arrangement of an additional connecting element between two adjacent connecting elements is no longer necessary. Preferably, but not exclusively, the additional connecting element can be a snap-in element.

[0075] By way of example, but not exclusively, the clamping spring can be secured using a threaded pin.

[0076] The tension of the fabric increases with the size of the frame. Therefore, the clamping force of the clamping spring must be at least as great as the tension of the fabric, otherwise the frame would shrink itself.

[0077] The clamping force of the clamping spring is dimensioned so that it is greater than or equal to the opposing tissue tension. Recording chamber

[0078] A receiving chamber is arranged in each of the corner connector and the connecting element.

[0079] The fabric is arranged exposed in the receiving chamber. The exposed arrangement of the fabric in each receiving chamber allows the inner and outer profiles of the frame to be telescopically displaced relative to each other.

[0080] To tighten the fabric when telescoping the inner profiles and the outer profiles against each other, the fabric can be guided over an edge arranged on the inner profile or the outer profile. Embodiments of the invention

[0081] According to one embodiment of the invention, a groove is arranged in the inner and outer profiles of the frame. The grooves are connected to the first receiving chamber and the second receiving chamber for receiving a fabric.

[0082] In another embodiment, the frame comprises a fabric comprising a fabric border.

[0083] According to a further embodiment of the invention, the connecting element has a recess for receiving the clamping spring.

[0084] In an additional embodiment of the invention, the connecting element for fastening the clamping spring comprises a support surface and / or an anchorage. Advantages of the invention

[0085] The fabric is already integrated into the inner and outer profiles of the frame.

[0086] With the help of the fabric border, the fabric is fixed in the inner profile, which is designed as a hollow profile, and in the outer profile, which is designed as a hollow profile, of the frame.

[0087] The frame can be telescoped to any size thanks to the elasticity of the fabric, including the inner and outer profiles of the frame.

[0088] All parts and components of the frame are already pre-assembled and ready to use, so that only the corners of the frame and their covers need to be connected to each other.

[0089] The clamping spring located on the connecting element allows the frame to be secured to any size. Alternatively, the frame can be secured by the clamping action of the clamping spring, eliminating the need for additional locking elements.

[0090] The window does not need to be measured before installing the frame. Thanks to its telescopic design, the frame can be adjusted directly to the size of the respective window.

[0091] The corner connectors and the connecting element allow the mesh to be guided freely with the mesh border. This allows the frame to be telescoped when assembled and with the mesh already inserted into the frame.

[0092] In the area of ​​the corner connector, the fabric border runs within the corner connector's receiving chamber. The fabric can be tightened over one edge of the receiving chamber. Drawings
