Description
Arrangement of profiles with thermal insulation The present invention relates to an arrangement of thermally insulated profiles according to the preamble of claim 1. It is known to provide, between the fixed frame and the sash frame, for example, of a door or window, an insulating arrangement, in particular a thermal insulation arrangement. In this case, the fixed frame is provided with a first insulating body and the sash frame with a second insulating body. When the window or door is closed, the insulating bodies are in contact with each other. Such an arrangement is known, for example, from documents DE 102005032176 A1, DE 202015103800 U1, DE 19730033 A1, and DE 102014222507 A1. In this case, the insulating bodies are mounted on the respective opposing insulating webs of the fixed and sash frames. The arrangement of the insulating elements in the area between the fixed frame and the sash frame, particularly between opposing insulating cores, requires very high dimensional accuracy. Any deviations will prevent the door or window from closing properly. For this reason, EP 2088276 A2 discloses a profile arrangement in which the two insulating bodies, when the window or door is closed, are separated by a gap of between 0 and 2 mm. Therefore, advantageous thermal insulation can be achieved without requiring tight tolerances for the insulating bodies or other profile components. However, the solution described in EP 2088276 A2 has the disadvantage of slightly reducing the insulation properties. Furthermore, it is often necessary to move the insulating cores between the outer and inner halves of the fixed and sash frames, which further compromises the insulation properties. Finally, by rotating the sash frame outwards, the separation described in EP-276 A2 can be reduced to such an extent that friction occurs between the two insulating bodies. Based on the problem mentioned above, the present invention aims to provide improved insulation for profile arrangements, which enhances the insulation properties and, at the same time, takes into account the outward turning behavior of the leaf frame. The object mentioned above is resolved by the object of independent claim 1. Further advantageous developments are indicated in the attached dependent claims. Therefore, the present invention relates to an arrangement of profiles for a window or a door, comprising: - a fixed frame with a first profile and a second profile, wherein the first profile and the second profile are connected by at least one insulating core; - a leaf frame with a first profile and a second profile, wherein the first profile and the second profile are connected by at least one insulating web; - a first insulating body, which is mounted on at least one insulating core of the fixed frame; - a second insulating body, which is mounted on at least one insulating core of the fixed 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 between them, when the window or door is closed, a separation open on both sides. The separation distance is greater than 0 mm but less than or equal to 2 mm. The insulating bodies are configured such that the separation extends obliquely with respect to the longitudinal direction of the insulating cores. The inclined configuration of the separation between the insulating bodies further impedes heat transfer, particularly by convection. Furthermore, the inclined arrangement causes the facing surfaces of the insulating bodies to be perpendicularly separated from each other when the leaf frame is rotated outwards, so that they do not come into contact even at the smallest gap. Consequently, abrasion of the insulating bodies is effectively prevented. According to another embodiment, the separation distance between the two insulating bodies is substantially constant. This is a relatively simple implementation of the profile arrangement, which can be produced quickly and repeatedly. Of course, as an alternative, it is also possible to configure the separation distance between the two insulating bodies variably, particularly in a staggered fashion. With such a design, air chambers can be formed between the two insulating bodies, which act as a trap for outside air and prevent unwanted convection. According to another embodiment, the separation extends at an acute angle, preferably between 1° and 45°, with respect to the longitudinal direction of the insulating cores. Such an acute angle is particularly advantageous with regard to the outward rotation of the sash frame during opening and closing. According to another embodiment, the first profiles of the fixed frame and the sash frame are configured as interior profiles, located on the inside of the door or window, and the second profiles of the fixed frame and the sash frame are configured as exterior profiles, located on the outside of the door or window. In this case, the gap is inclined towards the first profile of the sash frame and / or towards the second profile of the fixed frame. This inclination is designed, in particular, for the outward swing movement of tilt-and-turn windows. According to another embodiment, the two insulating bodies have a substantially identical shape. Therefore, the manufacturing effort required to achieve an oblique separation of the insulating bodies is considerably reduced. According to another embodiment, the insulating body has a first surface and a second surface opposite the first surface. The first surface extends substantially parallel to a longitudinal direction of the insulating web of the fixed frame and, preferably, is in contact with the insulating web of the fixed frame.The second surface extends obliquely with respect to the longitudinal direction of the insulating web of the fixed frame, wherein the second insulating body has a first surface and an opposing second surface, wherein the first surface extends substantially parallel to a longitudinal direction of the insulating web of the leaf frame and, preferably, is in contact with the insulating web of the leaf frame, and wherein the second surface extends obliquely with respect to the longitudinal direction of the insulating web of the leaf frame. In other words, the insulating bodies are arranged in a substantially wedge shape and have a first surface that extends parallel to the insulating webs and can be used to connect the insulating bodies to the insulating webs in a simple and reliable manner. The opposing second surface of the insulating bodies then forms the oblique separation in a simple manner. According to another embodiment, the second surface of the first or second insulating body is irregular and configured, in particular, with protrusions, grooves, or striations. The irregular configuration of the insulating bodies creates a plurality of air spaces in the separation between them, which can reduce heat losses from the profile arrangement. According to another embodiment, the first surface of the first and / or second insulating body has at least one recess to accommodate an anchoring portion of at least one insulating core. The anchoring portion can extend, for example, perpendicular to the insulating core. The insulating bodies can be fitted onto the anchoring portion by their first surface. Consequently, this embodiment has the advantage that the insulating bodies can be mounted on the profile arrangement very quickly, easily, and repeatedly. According to another embodiment, the sash frame has a second insulating core, which is positioned between and connected to the first and second profiles of the sash frame. The present invention is described in more detail below with reference to the embodiments shown in the figures. The figures show: FIG. 1 shows a schematic cross-section of a profile arrangement according to a first embodiment of the present invention; and FIG. 2 shows a cross-section of a second embodiment of the profile arrangement according to the present invention. FIG. 1 shows a cross-section through a profile arrangement according to a first embodiment of the present invention. The profile arrangement has a fixed frame 10 and a leaf frame 12. The fixed frame 10 has a first profile 1 on the outside and a second profile 2 on the inside. The two profiles 1 and 2 of the fixed frame 10 are connected to each other by an insulating web 11, but are thermally isolated from each other. The leaf frame has a first profile 3 on the outer side, as well as a second profile 4 on the inner side. The two profiles 3, 4 of the leaf frame 12 are connected to each other by at least one insulating web, in this case two insulating webs 13, 14. The first two profiles 1 and 3 of the profile arrangement form the outer profile, while the second two profiles 2 and 4 form the inner profile, i.e., the profile facing the interior of the building. The insulating cores 11, 13, and 14 are preferably made of a material with low thermal conductivity, such as polyamide. Profiles 1, 2, 3, and 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. In the rebate area between the fixed frame and the sash frame, two insulating bodies 21, 22 are provided. Specifically, a first insulating body 21 is arranged between opposing sections of the first profile, the first insulating web, and the second profile 2 of the fixed frame. The second insulating body 22 is arranged between opposing sections of the first profile 3, the second profile 4, and the first insulating web 13 of the sash frame 12. The first insulating body 21 is mounted on the first insulating web 11 of the fixed frame 10. The second insulating body 22 is mounted on the first insulating web 13 of the leaf frame. The insulating bodies 21 and 22 face each other and form a gap S in the space between them. The thermal conductivity of the insulating bodies 21 and 22 should be as low as possible in order to keep the heat transfer coefficient as low as possible. For this purpose, the insulating bodies 21 and 22 can be formed, for example, from foam, sponge rubber, or similar materials. The two insulating bodies 21, 22 are configured such that the gap S extends obliquely with respect to a longitudinal direction of the insulating webs 11, 13. In other words, a longitudinal direction of the gap S extends at an acute angle, preferably from 1° to 45°, and more specifically from 10° to 30°, with respect to the longitudinal direction of the insulating webs 11, 13. This oblique arrangement of the gap S results in a further improvement of the thermal transmittance coefficient, as well as a reduction in wear when opening the window or door. This is particularly relevant since the sash frame is typically rotated outwards when opening the window or door, resulting in a curvilinear movement of the sash frame relative to the fixed frame.Such curvilinear movement can, in a straight execution of the separation, such as that known, for example, from document EP 2088276 B1, result in undesirable contact between the insulating bodies. This is prevented by the oblique execution of the separation S shown in this case. The insulating bodies 21, 22 are configured such that the separation S is inclined, at its first end on the outer side, towards the first profile 1 of the fixed frame, while the separation S is inclined, at the opposite second end, which faces the inner side, towards the second profile 4 of the leaf frame. In other words, in the representation shown in FIG. 1, the separation S is inclined counterclockwise, forming an acute angle with respect to the longitudinal direction of the insulating webs 11, 13. The insulating bodies 21, 22 have respective first surfaces 23, 24, each of which is connected to the associated insulating webs 11, 13. In this case, 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 configured as a rail and extend substantially perpendicular to the longitudinal direction of the insulating webs. In this case, the anchoring elements 15 are housed in corresponding grooves of the first surface 23 of the first insulating body 21. Therefore, the first insulating body can be fitted onto the associated insulating web 11 in a particularly simple and repeatable manner. The second insulating body 22 is configured substantially identically to the first insulating body 21. This also has rail-like housings on the first surface 24, which are configured to accommodate the perpendicular ribs of the first insulating web 13 of the leaf frame 12. The two insulating bodies 21, 22 can be detachably connected to the insulating cores 11, 13, in particular to the anchoring elements 15. This particularly facilitates the replacement of the insulating bodies 21, 22 in case of wear. The first surfaces 23, 24 of the two insulating bodies 21, 22 are adapted to the surfaces of the insulating cores 11, 13. In the embodiment shown here, the first surfaces 23, 24 are therefore substantially rectilinear. On the opposite side of the insulating bodies 21, 22 are second surfaces facing the gap S. The second surfaces of the insulating bodies are configured obliquely. Consequently, the inclination of the second surfaces of the insulating bodies 21, 22 defines the orientation of the gap S. Therefore, the angle of the gap S can be easily obtained by using different insulating bodies 21, 22 with different second surfaces. As mentioned earlier, the oblique arrangement provides better thermal insulation and further reduces wear on the insulating bodies. Figure 2 shows a second embodiment of the present invention. The profile arrangement according to Figure 2 is substantially identical to the profile arrangement shown in Figure 1. Consequently, the identical parts of the profile arrangement in Figure 2 are provided with identical reference markings. The profile arrangement according to Figure 2 differs substantially in the shape of the gap S1 between the two insulating bodies 21, 22, compared to the gap S according to Figure 1. In particular, the gap S1 of the second embodiment has a variable separation distance. In contrast, the separation distance S according to Figure 1 is constant. The separation S1 according to FIG. 2 is, in particular, staggered, such that a plurality of air spaces 25 are present, connected to each other by narrower connecting channels. The air spaces act as heat transfer buffers and can further reduce the thermal transmittance coefficient. In FIG. 2, the staggered separation S1 is achieved, in particular, by a design with protrusions on 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 second surface that is protruding, striated, or grooved, in order to generate a variable separation distance. The present invention is not limited to the embodiments depicted in the figures, but arises from a joint consideration of all the features disclosed herein within the scope of the claims.
