Description

[0001] The present invention relates to a sash for a window or a door, wherein the sash comprises a sash frame formed from several profile sections with a main hollow chamber for receiving a reinforcement element and a fitting groove for at least partially receiving a fitting element; a surface element received in the sash frame; a fitting element received at least partially in the fitting groove; and a reinforcement element received in the main hollow chamber, composed of several interconnected components.

[0002] Such window and door sashes, as well as reinforcement elements for them, are widely known in the prior art. For example, EP 0 585 531 A1 describes such a sash with a sash frame made of a hollow chamber profile, in the main hollow chamber of which a reinforcement element, essentially rectangular in cross-section and open on one side, is accommodated. A fitting element designed as a lock case projects into the cavity enclosed by the reinforcement element, extending from the fitting groove of the sash frame. A disadvantage of the sash described in EP 0 585 531 A1 is that it offers relatively little burglary protection. Furthermore, the reinforcement element used in the sash according to EP 0 585 531 A1 contributes only to a limited extent to the sash's static stability.

[0003] DE 298 01 631 U1 describes a wing according to the preamble of claim 1.

[0004] Against this background, the object of the present invention is to provide a sash for a window or door that at least partially overcomes the disadvantages of the prior art. In particular, the sash according to the invention is intended to offer improved burglary protection. Furthermore, the reinforcing element used in the sash according to the invention is intended to give the sash increased stability compared to the prior art. Finally, the object of the present invention is also to provide a reinforcing element for such a sash.

[0005] According to the present invention, these and other problems are solved by a sash for a window or door having the features of claim 1. Preferred embodiments of the sash according to the invention are described in the dependent claims.

[0006] According to the present invention, it has been found that the burglar resistance of a window or door can be increased by restricting the pivoting range of a fitting element that projects into the cavity enclosed by the reinforcement element. The fitting's mechanism is attached to the sash frame from the outside by screws. During a burglary attempt, the mechanism can therefore be moved back and forth, exerting leverage on the fitting element, such as a lock case, which is partially recessed into the cavity of the reinforcement element. This leverage can cause locking elements, such as locking bolts, to protrude from the strike plates attached to the frame, thus allowing the window to be opened.According to the invention, this is countered by the fact that the reinforcing element, which has a substantially g-shaped cross-section, has at least one section that is arranged relative to a groove wall of the hardware groove and in extension of the groove wall of the hardware groove. If, during a break-in attempt, an attempt is made to open the window by acting on the mechanism, even a very slight pivoting of the hardware element causes it to contact the leg, so that further pivoting in this direction is no longer possible. In this way, the burglary protection of a window comprising the sash according to the invention is significantly increased. In addition, such a reinforcing element contributes significantly to the static stability of the sash according to the invention.

[0007] Accordingly, the present invention lies in providing a sash for a window or door, comprising a sash frame formed from several profile sections with a main hollow chamber for receiving a reinforcing element and a fitting groove for at least partially receiving a fitting element; a surface element received in the sash frame; a fitting element received at least partially in the fitting groove; and a reinforcing element received in the main hollow chamber, composed of several interconnected components, wherein the sash is characterized according to the invention in that the reinforcing element has a substantially g-shaped cross-section and has at least one component having at least one section arranged parallel to a groove wall of the fitting groove and extending from the groove wall of the fitting groove.Furthermore, the present invention provides a reinforcement element for a wing, wherein the reinforcement element has a substantially g-shaped cross-section and is composed of at least three components, wherein two components jointly surround a two-sided open cavity and the further component is arranged on a component surrounding the cavity, wherein the reinforcement element is characterized according to the invention in that one of the components surrounding the cavity is formed at least partially as a double wall.

[0008] With regard to the sash according to the invention, it is preferred if the at least one section of the reinforcing element, which is arranged parallel to a groove wall of the hardware groove and extending along this groove wall of the hardware groove, has a contact surface for at least partially supporting the hardware element. Here, a "contact surface" is understood to be a partial surface of a component of the reinforcing element against which a part of the hardware element comes into contact when the hardware element is pivoted slightly, for example, by an angle in the range of 2° to 15°, and in particular 3° to 10°. Such a contact surface further contributes to the burglar resistance of a window comprising a sash according to the invention.

[0009] According to the invention, two components of the reinforcement element each comprise at least one section that is arranged parallel to a groove wall of the fitting groove and in extension of this groove wall of the fitting groove. In this way, pivoting of the fitting element in two directions by external intervention is restricted, which further significantly improves burglary protection.

[0010] It can also be advantageous if one of the components of the reinforcement element comprises a further component arranged essentially orthogonally to the component, on which an additional contact surface is arranged. Such an additional contact surface can significantly restrict the pivoting in both directions of the fitting element, which is partially integrated into the main hollow chamber of the sash profile of the sash according to the invention. This results in a considerable improvement in the burglar resistance of a window or door comprising a sash according to the invention. It can be particularly beneficial if the further component is double-walled, at least in the area of ​​the additional contact surface. Double walls considerably increase the statically stabilizing factor transferred from the reinforcement element to the sash according to the invention.

[0011] For this reason, it can also be helpful if at least one of the sections of the reinforcing element, each arranged parallel to a groove wall of the fitting groove and each extending from this groove wall of the fitting groove, has a double-wall thickness in the area of ​​the contact surface. Preferably, this applies to both such sections of the reinforcing element if the reinforcing element has two such sections, each arranged parallel to a groove wall of the fitting groove and each extending from this groove wall of the fitting groove.

[0012] Preferably, the frame profiles for both the sash frame and the frame are multi-chamber hollow profiles, in particular multi-chamber plastic hollow profiles or multi-chamber aluminum hollow profiles, with plastic hollow profiles being particularly preferred. This makes the design of the window according to the invention as a plastic window particularly preferred.

[0013] In relation to das The reinforcement element can be advantageous if the double-walled structure of the component forms a step creating two sections, allowing one of the sections to be arranged parallel to a groove wall of the hardware groove (6) of a sash profile in whose main cavity the reinforcement element is located. This ensures that the pivoting of a hardware component received in the cavity of the sash according to the invention is significantly restricted, thus considerably increasing the burglar resistance of such a window according to the invention.

[0014] Furthermore, it can be advantageous if the additional component is arranged essentially orthogonally to the component of the reinforcing element to which the additional component is attached. Such an embodiment of the reinforcing element according to the invention is able to significantly reduce the pivoting in two directions of a fitting part received in the hollow chamber of the wing according to the invention.

[0015] To improve the static stability and increase the burglary protection resulting from the reinforcement element according to the invention, it can be helpful if the further component is at least partially double-walled.

[0016] Der The wing, the reinforcing element, and individual parts thereof can also be manufactured line by line or layer by layer using a line-by-line or layer-by-layer manufacturing process (e.g., 3D printing). However, the wing frame profile is preferably manufactured by extrusion and cut into spars, which are mitered and welded or joined together. For the reinforcing element according to the invention, rolling from a predetermined sheet of metal is the preferred manufacturing method. Preferred embodiments of the present invention are explained in more detail below with reference to the accompanying drawings. Fig. 1 a cross-sectional view of a window sash according to the state of the art; Fig. 2 a cross-sectional view of a window sash according to an example that is not within the scope of the attached claims; and Fig. 3 a cross-sectional view of a window sash according to an embodiment of the present invention.

[0017] In Fig. 1 A sash 1 for a window according to the state of the art is shown in cross-sectional view, using the example of a window sash with a sash frame 2 designed as a hollow plastic profile frame. The sash frame 2 is made of polyvinyl chloride. The sash frame 2 includes a glazing rebate 3, into which a surface element 5, designed as triple insulating glass and held by a retaining strip 4, is received. On the side opposite the glazing rebate 3, the sash frame 2 has a hardware groove 6 into which a hardware element 7, designed as a strike plate, is inserted. The hardware element 7 penetrates the base of the groove 6 and projects into a main hollow chamber 8, usually also referred to as a reinforcement chamber, which is arranged centrally in the profile of the sash frame 2. A reinforcing element 9, designed as steel reinforcement, is received in the main hollow chamber 8.The reinforcement element 9 is formed from several legs and has a substantially C-shaped cross-section, with the fitting element 7 projecting through the open side of the reinforcement element 9 into the cavity surrounded by the legs of the reinforcement element 9. Due to the C-shaped cross-section, the legs of the reinforcement element are spaced a considerable distance from the side surfaces of the fitting element 7. If the window encompassing the sash 1 is to be forced open from the outside during a burglary attempt, the drive band 10 can be actuated from the outside with a screwdriver. This action is transmitted to the fitting element 7, which is designed as a strike plate, and can thereby be rotated in two directions. These two directions are shown in . Fig. 1 This is indicated by a double arrow. Since the sides of the fitting element 7 are relatively far apart from the legs of the reinforcement element 9, the fitting element 7 has a relatively large range of movement in both directions. This makes it possible to release the locking bolt 11 of the fitting element 7 from a strike plate attached to the frame, which, when the window is closed, engages in a strike plate attached to the window frame. Releasing the locking bolt 11 from the strike plate releases the window from opening.

[0018] Fig. 2 In contrast, Figure 1 shows a sash 1 for a window according to an example that does not fall within the scope of the appended claims, also using the example of a window sash with a sash frame designed as a hollow plastic profile frame in a cross-sectional view. The hollow chamber profile of the sash frame 2 is made of a thermoplastic polymer material, preferably polyvinyl chloride (PVC), in particular rigid PVC (PVC-U) or glass fiber reinforced PVC, to which additives such as stabilizers, plasticizers, pigments, and the like are added. It is composed of a plurality of hollow chambers, each of which is surrounded by webs of the sash frame 2. Centrally, the profile of the sash frame 2 again comprises a main hollow chamber 8 in which a reinforcing element 9 designed as a steel reinforcement is received. The sash frame 2 is installed according to Figure 1. Fig. 2 The upper web 12 of the main hollow chamber 8, together with an outer overlap 13, forms a glass rebate 3. On the side opposite the outer overlap 13, the profile of the sash frame 2 has a retaining strip groove in which the retaining strip 4 is anchored, which in the illustrated embodiment is designed as a glass retaining strip and by which a schematically shown surface element, in particular an insulating glass unit, preferably a double or triple insulating glass unit, is stabilized in the glass rebate 3.

[0019] On the side opposite the upper web 12, the sash frame 2 has a fitting groove 6. The fitting groove 6 is bounded by two groove walls 14.1 and 14.2 and a groove base 15. Over a large part of its depth, the two groove walls 14.1 and 14.2 are arranged parallel to each other. A fitting element 7, designed as a lock case with locking bolt 11, is fixed in the fitting groove 6. The fitting element 7 penetrates the groove base 15 and thus projects into the main cavity 8 of the sash frame 2 and an open side of the reinforcement element 9.

[0020] The reinforcing element 9 is formed from several components 16, 17, 22, which are integrally connected, and has a substantially g-shaped cross-section. Component 16 and component 17 of the reinforcing element 9 together enclose a two-sided open cavity, which in the illustrated embodiment has a substantially rectangular cross-section with rounded corners. Component 17 extends laterally beyond the cavity. A further component 22 is formed substantially orthogonally to this extended part of component 17 via a rounded corner. The further component 22 abuts a profile wall 20 of the profile frame 2. By simply folding over an end piece of component 16 of the reinforcing element 9, a step is formed, which divides this side into two sections 18.1 and 18.2. The two sections 18.1 and 18.2Section 2 runs largely parallel to the groove wall 14.1. Additionally, section 18.2 lies in the extension of the groove wall 14.1. Thus, there is only a very small gap between section 18.2 of the reinforcement element 9 and the fitting element 7. In this way, one side of the fitting element 7 rests against a contact surface 19 of section 18.2 after only a very slight rotation. In the area of ​​the contact surface 19, section 18.2 is double-walled. Overall, the sash 1 according to the invention provides a significantly increased burglar protection to a window or door encompassing it.

[0021] The present invention will now be explained with reference to an embodiment described in Fig. 3 is shown. To avoid repetition, only the differences between the example according to are mentioned here. Fig. 2 and according to the embodiment Fig.3 received. Otherwise, the statements regarding the example apply according to Fig. 2 Accordingly. Identical reference symbols represent identical elements.

[0022] Fig. 3 Figure 1 shows another embodiment of the wing 1 according to the invention in a cross-sectional view. The embodiment of the wing 1 according to the invention is shown in Figure 1. Fig. 3 differs from the example according to Fig. 2 only with regard to the design of the reinforcing element 9 according to the invention. Fig. 3The additional component 22 is shortened and double-walled. This additional component 22 has a section 24 that runs largely parallel to the groove wall 14.2 of the fitting groove 6 and is arranged as an extension of the groove wall 14.2. The additional component 22, which is arranged orthogonally to component 17, has only a small gap to the fitting element 7 on its side facing the fitting element 7. If the fitting element 7 is rotated slightly, it abuts against an additional contact surface 25 located on the additional leg 22.

[0023] In addition, section 18.2 of component 16 also runs parallel to the groove wall 14.1 of the fitting groove 6 and is arranged in the extension of the fitting groove 14.1. This limits the degree of rotation of the fitting element 7 in both pivot directions by external force acting on the drive band 10. As a result, the sash 1 according to the invention provides a window containing it with significantly increased burglar protection.

[0024] The invention has been explained in detail above with reference to a window sash. It is understood that the explanations also apply accordingly to a door sash. A hollow plastic profile frame is described as an example of a profile frame. The explanations also apply accordingly to other types of profile frames, for example, aluminum profile frames, wooden profile frames, aluminum-plastic composite profile frames, aluminum-wood composite profile frames, and the like.
