Description

[0001] The present invention relates to a profile arrangement with thermal insulation according to the preamble of claim 1.

[0002] It is known to provide an insulating arrangement, in particular a thermal insulation arrangement, between the frame and the sash, for example, of a door or window. The frame has a first insulating element, and the sash has a second insulating element. When the window or door is closed, the insulating elements are in contact. Such an arrangement is known, for example, from DE 10 2005 032 176 A1, DE 20 2015 103800 U1, DE 197 30 033 A1, and DE 10 2014 222507 A1. In these arrangements, the insulating elements are mounted on the opposing insulating webs of the frame and sash.

[0003] Due to the arrangement of the insulating elements in the area between the frame and the sash, particularly between the opposing insulating strips, very precise dimensional accuracy of the insulating elements is essential. Any deviations here will prevent the door or window from closing properly.

[0004] For this reason, EP 2 088 276 A2 discloses a profile arrangement in which the two insulating bodies have a gap between them of between 0 and 2 mm when the window or door is closed. This allows for advantageous thermal insulation without requiring tight tolerances of the insulating bodies or the other profile components.

[0005] The solution known from EP 2 088 276 A2, however, has the disadvantage that the insulation properties are slightly reduced. It is also frequently necessary to reposition the insulating strips between the outer and inner half-shells of the frame and sash, which further impairs the insulation properties. Finally, the gap known from EP 276 A2 can be reduced so significantly, especially when the sash is turned outwards, that friction occurs between the two insulating elements.

[0006] Based on the above-mentioned problem, the present invention aims to provide improved insulation for profile arrangements, which improves the insulation properties and simultaneously takes into account the rotation behavior of the wing frame.

[0007] The problem described above is solved by the subject matter of independent claim 1. Advantageous embodiments are specified in the accompanying dependent claims.

[0008] Accordingly, the present invention relates to a profile arrangement for a window or door, comprising: a frame with a first profile and a second profile, wherein the first profile and the second profile are connected by at least one insulating spacer; a sash frame with a first profile and a second profile, wherein the first profile and the second profile are connected by at least one insulating spacer; a first insulating body attached to the at least one insulating spacer of the frame; a second insulating body attached to the at least one insulating spacer of the frame, wherein the insulating bodies face each other when the window or door is closed and the first insulating body and the second insulating body have a gap between them open on both sides when the window or door is closed.

[0009] The gap spacing is greater than 0 but less than or equal to 2 mm. The insulating elements are designed such that the gap runs obliquely to one longitudinal direction of the insulating webs.

[0010] The angled design of the gap between the insulation elements further reduces heat transfer, particularly through convection. This angled arrangement also ensures that the opposing surfaces of the insulation elements are perpendicular to each other when the sash frame is opened, preventing contact even with the smallest gap. This effectively prevents abrasion of the insulation elements.

[0011] In another embodiment, the gap between the two insulating bodies is essentially constant. This is a relatively simple embodiment of the profile arrangement, which can be produced quickly and repeatedly. Alternatively, it is of course also possible to make the gap between the two insulating bodies variable, particularly in a stepped manner. Such a design allows air chambers to form between the two insulating bodies, which act as a trap for outside air and prevent unwanted convection.

[0012] In a further embodiment, the gap runs at an acute angle, preferably at an angle between 1° and 45°, with respect to the longitudinal direction of the insulating webs. Such an acute angle is particularly advantageous with regard to the rotational movement of the sash frame during opening and closing.

[0013] In a further embodiment, the first profiles of the frame and the sash are designed as inner profiles, which are arranged on the inside of the door or window, and the second profiles of the frame and the sash are designed as outer profiles, which are arranged on the outside of the door or window. The gap is inclined in the direction of the first profile of the sash and / or in the direction of the second profile of the frame. Such an inclination is particularly suited to the opening movement of tilt-and-turn windows.

[0014] In another embodiment, the two insulating bodies have an essentially identical shape. This significantly reduces the manufacturing effort required to create an angled gap for the insulating bodies.

[0015] According to a further embodiment, the insulating body has a first surface and a second surface opposite the first surface. The first surface runs essentially parallel to a longitudinal direction of the insulating web of the frame and is preferably in contact with the insulating web of the frame. The second surface runs obliquely to the longitudinal direction of the insulating web of the frame, wherein the second insulating body has a first surface and a second, opposite surface, wherein the first surface runs essentially parallel to a longitudinal direction of the insulating web of the sash frame and is preferably in contact with the insulating web of the sash frame, and wherein the second surface runs obliquely to the longitudinal direction of the insulating web of the sash frame.In other words, the insulation elements are essentially arranged in a wedge shape, with a first surface running parallel to the insulating strips, which can be used to connect the insulation elements to the insulating strips simply and reliably. The opposing second surface of the insulation elements then easily forms the angled gap.

[0016] According to a further embodiment, the second surface of the first or second insulating body is uneven, in particular nubby, grooved, or ribbed. This uneven design of the insulating bodies creates numerous air spaces in the gap between them, which can reduce heat loss from the profile arrangement.

[0017] According to a further embodiment, the first surface of the first and / or the second insulating body has at least one recess for receiving an anchoring element of at least one insulating web. The anchoring element can, for example, run perpendicular to the insulating web. The insulating bodies can be attached to the anchoring element via their first surface. This embodiment therefore has the advantage that the insulating bodies can be attached to the profile assembly very quickly, easily, and repeatedly. According to a further embodiment, the sash frame has a second insulating web, which is arranged between and connected to the first and second profiles of the sash frame.

[0018] The present invention will now be described in more detail with reference to the embodiments shown in the FIGS.

[0019] This shows: FIG. 1 shows a schematic cross-section through a profile arrangement according to a first embodiment of the present invention; and FIG. 2 shows a cross-section through a second embodiment of the profile arrangement according to the present invention.

[0020] The FIG. 1 Figure 1 shows a cross-section through a profile arrangement according to a first embodiment of the present invention. The profile arrangement comprises a frame 10 and a sash frame 12. The frame 10 has a first, outer profile 1 and a second, inner profile 2. The two profiles 1 and 2 of the frame 10 are connected to each other via an insulating web 11, but are thermally separated from each other.

[0021] The sash frame has a first, outer profile 3 and a second, inner profile 4. The two profiles 3, 4 of the sash frame 12 are connected to each other by at least one insulating web, here two insulating webs 13, 14.

[0022] The first two profiles 1, 3 of the profile arrangement form the outer profile of the profile arrangement, while the second two profiles 2, 4 form the inner profile, i.e., the profile facing the interior of the building. The insulating webs 11, 13, 14 are preferably made of a material with poor thermal conductivity, such as polyamide. The profiles 1, 2, 3, 4 of the profile arrangement are made, for example, of a metallic material, such as aluminum. However, it is equally conceivable to apply the present invention to plastic or wooden profiles.

[0023] Two insulating elements 21 and 22 are provided in the rebate area between the frame and the sash. Specifically, a first insulating element 21 is arranged between the facing sections of the first profile (the first insulating web) and the second profile 2 of the frame. The second insulating element 22 is arranged between the facing sections of the first profile 3, the second profile 4, and the first insulating web 13 of the sash 12.

[0024] The first insulating element 21 is attached to the first insulating web 11 of the frame 10. The second insulating element 22 is attached to the first insulating web 13 of the sash frame. The insulating elements 21 and 22 face each other, forming a gap S between them. The thermal conductivity of the insulating elements 21 and 22 should be as low as possible to minimize the heat transfer coefficient. For this purpose, the insulating elements 21 and 22 can be made of materials such as foam, sponge rubber, or similar materials.

[0025] The two insulating elements 21, 22 are designed such that the gap S runs obliquely relative to a longitudinal direction of the insulating webs 11, 13. In other words, a longitudinal direction of the gap S runs at an acute angle, preferably at an angle of 1° to 45°, more preferably 10° to 30°, relative to the longitudinal direction of the insulating webs 11, 13. This oblique arrangement of the gap S leads to a further improvement in the thermal transmittance coefficient and to a reduction in wear when opening the window or door. This is particularly important because the sash frame is usually rotated when the window or door is opened, resulting in a curved movement of the sash frame relative to the frame. With a straight design of the gap, such as that known, for example, from EP 2 088 276 B1, such a curved movement can lead to undesirable contact between the insulating elements.This is prevented by the angled design of the gap S shown here.

[0026] The insulating elements 21, 22 are designed such that the gap S at its first, outer end slopes towards the first profile 1 of the frame, while the gap S at the opposite, second end, which is oriented towards the inside, slopes towards the second profile 4 of the sash frame. In other words, the gap S is in the FIG. 1 The representation shown is inclined counterclockwise at an acute angle to the longitudinal direction of the insulating webs 11, 13.

[0027] The insulating bodies 21, 22 each have a first surface 23, 24, which is connected to the associated insulating webs 11, 13. A first surface 23 of the first insulating body 21 is connected to anchoring elements 15 of the insulating web 11. The anchoring elements 15 of the insulating web 11 are rail-like and extend essentially perpendicular to the longitudinal direction of the insulating webs. The anchoring elements 15 are received in corresponding grooves on the first surface 23 of the first insulating body 21. This allows the first insulating body to be easily and repeatedly attached to the associated insulating web 11.

[0028] The second insulating body 22 is essentially identical in design to the first insulating body 21. It also has rail-like receptacles on the first surface 24, which are designed to receive the vertical webs of the first insulating web 13 of the sash frame 12.

[0029] The two insulating bodies 21, 22 can be detachably connected to the insulating webs 11, 13, particularly via the anchoring elements 15. This facilitates the replacement of the insulating bodies 21, 22 in case of wear.

[0030] The first surface 23, 24 of the two insulating bodies 21, 22 is adapted to the surface of the insulating webs 11, 13. In the embodiment shown here, the first surfaces 23, 24 are therefore essentially straight. On the opposite side of the insulating bodies 21, 22 are second surfaces facing the gap S. These second surfaces of the insulating bodies are inclined. Accordingly, the inclination of the second surfaces of the insulating bodies 21, 22 defines the orientation of the gap S. Thus, the angle of the gap S can be easily achieved by using different insulating bodies 21, 22 with different second surfaces. As mentioned above, the inclined arrangement results in improved thermal insulation and further reduces wear on the insulating bodies.

[0031] The FIG. 2 A second embodiment of the present invention can be seen from the following. The profile arrangement according to FIG. 2 is essentially identical to the one in FIG. 1 The profile arrangement shown. Accordingly, identical parts of the profile arrangement are in FIG. 2 provided with identical reference numerals. The profile arrangement according to FIG. 2 differs essentially in the shape of the gap S1 between the two insulating bodies 21, 22 compared to the gap S according to FIG. 1 In particular, the gap S1 of the second embodiment has a variable gap spacing. In contrast, the gap spacing of the gap S according to the FIG. 1 constant.

[0032] The gap S1 according to FIG. 2 The structure is particularly stepped, creating a multitude of air spaces 25, which are interconnected by narrower connecting channels. These air spaces act as thermal buffers and can further reduce the heat transfer coefficient. FIG. 2The stepped gap S1 is achieved in particular by a stud-like design of the second surfaces 27 of the first and second insulating bodies 21, 22.

[0033] Of course, it is also possible to provide only one of the two insulating bodies with a second surface resembling a nub, ribbed or grooved surface in order to generate a variable gap distance.

[0034] The present invention is not limited to the embodiments shown in the figures, but results from a combination of all the features disclosed herein within the scope of the claims.
