AI Technical Summary
Existing thermal insulation arrangements between window or door frames and sashes require precise dimensional accuracy, but known solutions either compromise insulation quality or lead to friction and wear when the sash frame is unscrewed, reducing insulation effectiveness.
A profile arrangement with obliquely designed gaps between insulating bodies attached to the frame and sash, where the gap runs at an acute angle (1° to 45°) relative to the longitudinal direction of the insulating webs, preventing heat transfer through convection and ensuring non-contact during unscrewing, and allowing for constant or variable gap distances to form air chambers for enhanced insulation.
This design significantly improves thermal insulation by reducing heat transfer and wear on insulating bodies, while allowing for easy attachment and replacement, and maintaining effective insulation even when the sash frame is unscrewed.
Abstract
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 comprises a first insulating body and the sash a second insulating body. When the window or door is closed, the insulating bodies touch each other. Such an arrangement is known, for example, from DE 10 2005 032 176 A1. Here, the insulating bodies are attached to the opposing insulating bars of the frame and sash.
[0003] Due to the arrangement of the insulation elements in the area between the frame and the sash, especially between the opposing insulating bars, very precise dimensional accuracy is required. Any deviations here will result in the door or window no longer closing properly.
[0004] For this reason, EP 2 088 276 A2 discloses a profile arrangement in which the two insulating elements have a gap 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 elements or the other profile components.
[0005] However, the solution known from EP 2 088 276 A2 has the disadvantage that the insulation properties are slightly reduced. It is also often necessary to offset the insulating bars between the outer and inner half-shells of the frame and the sash, which further impairs the insulation properties. Finally, the gap known from EP 276 A2 can be reduced to such an extent, especially when turning out the sash, that friction occurs between the two insulating bodies.
[0006] Based on the above-mentioned problem, the present invention is based on the object of providing an improved insulation for profile arrangements which improves the insulation properties and at the same time takes into account the turning behavior of the sash frame.
[0007] The above-mentioned object is solved by the subject matter of independent patent claim 1. Advantageous further developments are specified in the appended dependent patent claims.
[0008] Accordingly, the present invention relates to a profile arrangement for a window or a door, comprising: a window frame with a first profile and a second profile, wherein the first profile and the second profile are connected by at least one insulating bar; 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 bar; a first insulating body which is attached to the at least one insulating bar of the window frame; a second insulating body which is attached to the at least one insulating bar of the window 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 that is 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 insulation bodies are designed such that the gap runs diagonally relative to the longitudinal direction of the insulation bars.
[0010] The angled gap between the insulation elements further prevents heat transfer, particularly through convection. The angled arrangement also ensures that the opposing surfaces of the insulation elements are vertically spaced apart when the sash frame is turned out, preventing contact even with the smallest gap. This effectively prevents abrasion of the insulation elements.
[0011] According to another embodiment, the gap spacing between the two insulating bodies is essentially constant. This represents a relatively simple embodiment of the profile arrangement, which can be produced quickly and repeatably. Of course, it is also possible to design the gap spacing between the two insulating bodies in a variable manner, 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] According to a further embodiment, the gap runs at an acute angle, preferably between 1° and 45°, relative to the longitudinal direction of the insulating bars. Such an acute angle is particularly advantageous with regard to the outward rotation of the sash frame during opening and closing.
[0013] According to 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 toward the first profile of the sash and / or toward the second profile of the frame. Such an inclination is particularly designed for the opening movement of tilt / turn windows.
[0014] According to a further embodiment, the two insulating bodies have a substantially identical shape. This significantly reduces the manufacturing effort for the insulating bodies to achieve an inclined gap.
[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 substantially parallel to a longitudinal direction of the insulating bar of the frame and is preferably in contact with the insulating bar of the frame. The second surface runs obliquely to the longitudinal direction of the insulating bar of the frame, wherein the second insulating body has a first surface and a second, opposite surface, wherein the first surface runs substantially parallel to a longitudinal direction of the insulating bar of the sash frame and is preferably in contact with the insulating bar of the sash frame, wherein the second surface runs obliquely to the longitudinal direction of the insulating bar of the sash frame.In other words, the insulating bodies are arranged in a substantially wedge-shaped manner, with a first surface running parallel to the insulating bars, which can be used to easily and reliably connect the insulating bodies to the insulating bars. The opposite second surface of the insulating bodies then easily forms the inclined gap.
[0016] According to a further embodiment, the second surface of the first or second insulating body is uneven, in particular knob-like, groove-like, or ridged. The uneven design of the insulating bodies creates a multitude of air spaces in the gap between the insulating bodies, which can reduce heat loss from the profile arrangement.
[0017] According to a further embodiment, the first surface of the first and / or second insulating body has at least one recess for receiving an anchoring part of at least one insulating strip. The anchoring part can, for example, run perpendicular to the insulating strip. The insulating bodies can be plugged onto the anchoring part via their first surface. This embodiment therefore has the advantage that the insulating bodies can be attached to the profile arrangement very quickly, easily, and repeatedly. According to a further embodiment, the sash frame has a second insulating strip, which is arranged between the first profile and the second profile of the sash frame and is connected to the latter.
[0018] In the following, the present invention is described in more detail with reference to the embodiments shown in the FIGS.
[0019] Showing: 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 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 12. The frame 10 has a first, outer profile 1 and a second, inner profile 2. The two profiles 1, 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 via at least one insulating bar, here two insulating bars 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 of a metallic material, such as aluminum, for example. However, it is equally conceivable to apply the present invention to plastic or wooden profiles.
[0023] Two insulating bodies 21, 22 are provided in the rebate area between the frame and the sash. In particular, a first insulating body 21 is arranged between facing sections of the first profile, the first insulating bar, and the second profile 2 of the frame. The second insulating body 22 is arranged between facing sections of the first profile 3, the second profile 4, and the first insulating bar 13 of the sash 12.
[0024] The first insulating body 21 is intended to be attached to the first insulating strip 11 of the frame 10. The second insulating body 22 is attached to the first insulating strip 13 of the sash frame. The insulating bodies 21, 22 are positioned opposite each other and form a gap S in the space between them. The thermal conductivity of the insulating bodies 21, 22 should be as low as possible to keep the thermal transmittance as low as possible. For this purpose, the insulating bodies 21, 22 can be made of foam, foam rubber, or similar materials, for example.
[0025] The two insulating bodies 21, 22 are designed such that the gap S runs obliquely with respect 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°, with respect 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 and to a reduction in wear when the window or door is opened. This is particularly the case because the sash frame is usually rotated outwards when the window or door is opened, resulting in a curved movement of the sash frame relative to the frame. Such a curved movement can lead to undesired contact between the insulating bodies in a straight design of the gap, as is known, for example, from EP 2 088 276 B1.This is prevented by the slanted design of the gap S shown here.
[0026] The insulating bodies 21, 22 are designed in such a way 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 inner side, slopes towards the second profile 4 of the sash frame. In other words, the gap S is in the FIG. 1 shown illustration 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 attached to the associated insulating web 11 in a particularly simple and repeatable manner.
[0028] The second insulating body 22 is essentially identical 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, in particular, be detachably connected to the insulating bars 11, 13 via the anchoring elements 15. This particularly facilitates the replacement of the insulating bodies 21, 22 in the event 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 exemplary embodiment shown here, the first surfaces 23, 24 are therefore essentially rectilinear. On the opposite side of the insulating bodies 21, 22 there are second surfaces which face the gap S. The 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. The angle of the gap S can thus be very easily achieved by using different insulating bodies 21, 22 with different second surfaces. As already mentioned above, the inclined arrangement achieves better thermal insulation and further reduces wear on the insulating bodies.
[0031] The FIG. 2 A second embodiment of the present invention can be seen. The profile arrangement according to FIG. 2 is essentially identical to that in FIG. 1 shown profile arrangement. Accordingly, identical parts of the profile arrangement are FIG. 2 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 distance. In contrast, the gap distance of the gap S according to the FIG. 1 constant.
[0032] The gap S1 according to FIG. 2 is particularly stepped, creating a multitude of air spaces 25 that are connected to each other by narrower connecting channels. The air spaces serve as heat transfer buffers and can further reduce the heat transfer coefficient. FIG. 2The stepped gap S1 is achieved in particular by a knob-like configuration of the second surfaces 27 of the first and second insulating bodies 21, 22. Of course, it is also possible to provide only one of the two insulating bodies with a knob-like, ribbed, or groove-like second surface in order to generate a variable gap spacing.
[0033] The present invention is not limited to the embodiments shown in the figures, but results from a combination of all features disclosed herein.
