EP3106600B1 - Hidden frame assembly for windows, doors or curtains facades - Google Patents

Description

The invention relates to a hidden frame assembly for windows, doors or curtain walls. The frame assembly has an outside profile, an inside profile, and a disc assembly clamped between the outside profile and the inside profile.

The publication GB 2 502 614 A relates to a frame assembly for windows, doors or curtain walls with an outside profile, an inside profile and a disc arrangement clamped between the outside profile and the inside profile. The frame assembly is partially concealed attachable to an outer wall such that between an outer end region of the outside profile facing the pane arrangement and the outside wall an oblique transition element is arranged.

Known frame arrangements are usually made of aluminum or plastic and likewise have an outside profile, an inside profile and a pane arrangement clamped between the profiles. The outside profile is connected to the inside profile by thermal insulation elements to improve the heat transfer coefficient (K value) of the frame assembly. The known profiles often have a lower heat transfer coefficient than the disk assembly itself.

Especially in geographic areas where there are large differences between indoor and outdoor temperatures, for example in high-altitude regions Solar radiation or pronounced continental climate, a significant heat transfer between an outer and an inner side can be present in particular by the sunlight on the profiles. In the case that the profiles are made of aluminum, the outside profile heats up strongly in sunlight, which can lead to a high heat transfer to the inside profile and thus to the inside.

In known frame assemblies high design effort is driven to reduce the heat transfer coefficient of the profiles. For example, thermal insulating webs are provided between the outside profile and the inside profile and additionally provided insulation materials in profile cavities.

In addition, frame arrangements are often visually disturbing, as an outer facade should be made visually appealing by large glass surfaces, without the frame of the glass surfaces to contribute to the visual appearance.

Based on the above-mentioned problem, the present invention has the object to further improve the thermal insulation and the optical appearance of known frame arrangements.

According to the invention the above object is achieved by the independent claims 1 and 4. Further developments are specified in the dependent claims.

Accordingly, the present invention is characterized in that the frame assembly is attached to an outer wall attachable such that from a perpendicular to the surface extension of the disc assembly along the outer wall extending line of sight from the frame assembly is not visible.

The advantages of the invention are obvious. By arranging the frame assembly from an outside as seen behind the outer wall, the profiles are not visible from the outside. Thus, viewed from the outside, the outer wall optically seamlessly transitions into glass surfaces.

In addition, the thermal properties of the frame assembly are significantly improved, since from the outside incident on the frame assembly sunlight or incident heat radiation does not hit the outside profile or the inside profile, but only meets the disc assembly. In practice, since the heat transfer coefficient of the disk arrangement, by arranging several disks in succession and the optional provision of, for example, an inert gas between the disks, is lower than the heat transfer coefficient of the profiles, the total thermal performance of the frame assembly can be improved compared to known frame arrangements.

Also, the surface of the profiles which are in direct contact with the outside is reduced in comparison to known frame arrangements, whereby the heat transfer by convection, heat conduction and heat radiation can be reduced compared to known frame orders.

According to one aspect of the invention, it is provided that the outside profile is connected to the inside profile by thermal insulating webs, which are preferably made of plastic.

As a result, the heat transfer coefficient of the profiles can be further improved, and thus overall the thermal performance of the frame assembly (ie the profiles and the disc assembly) can be improved.

According to the invention it is provided that the outside profile has a thermal insulation in the outside region of the profile.

This ensures that the part of the outside profile, which faces the outside, is optimized in terms of thermal performance. In particular, it can be achieved synergistically that the surface of the profiles facing the outside is reduced according to the invention, and moreover the reduced surface facing the outside has thermal insulation. This further improves the overall thermal performance of the frame assembly.

According to the invention it is further provided that the thermal insulation is formed as a cavity which is enclosed by the outside profile.

The so enclosed cavity provides improved compared to known frame arrangements heat transfer coefficient. Preferably, the cavity may be filled with an inert gas or even more preferably comprise insulating materials.

According to a further aspect of the invention, provision is made for a guide rail for guiding roller shutter elements to be formed adjacent to the thermal insulation.

This ensures that, on the one hand, thermal insulation is ensured and, on the other hand, roller shutter elements can be arranged in such a way that they are not visible from the outside.

In this way, a roller shutter adjacent to the frame assembly can be arranged so that no roller shutter elements are visible in the frame assembly when the shutter is not closed. When the roller shutter is closed again, only the roller shutter elements are visible, which cover the disc assembly, but not other roller shutter elements such as guide elements of the shutter or the guide rail of the shutter.

The object is further achieved by a partially hidden frame assembly having an outside profile and an inside profile and a between the outside profile and the inside profile clamped disc assembly. In this case, the frame assembly is partially hidden attached to an outer wall by a slanted transition element is disposed between an outer end portion of the outer side profile facing the disc assembly and the outer wall. Seen from the outside, i. seen from a perpendicular to the surface extension of the disc assembly along the outer wall extending line of sight, only the transition element is visible.

Advantageously, a partially hidden frame arrangement can be used if there is little space in the area of the outer wall to which the frame assembly is to be attached. In this case, the profiles protrude slightly over the outer wall such that, viewed from the outside, the profiles would be partially visible. In this case, the transition element is used so that not the outside profile or the inside profile of the frame assembly is visible, but only the optically advantageous oblique transition element.

Die bekannte Rahmenanordnung ist an einer Außenwand 4' befestigt. Die Profile der Rahmenanordnung können von der Außenseite her gesehen werden, und Sonnenlicht kann zumindest auf das Profil 1' fallen.In addition, the inclined transition element improves the thermal performance of the frame assembly. More precisely, between the transitional element, which is directly in contact with the outside, and a cavity provided to the outside profile, so that a heat transfer between the outside and the outside profile is reduced and thus the thermal performance of the frame assembly is improved.

Fig. 1 shows a known frame assembly in which an outside profile 1 ', an inside profile 2', a disc assembly 3 'and the outside profile 1' and the inside profile 2 'connecting insulating webs 5' are provided.
The known frame assembly is attached to an outer wall 4 '. The profiles The frame arrangement can be seen from the outside, and sunlight can at least fall on the profile 1 '.

Fig. 2a shows a hidden frame assembly according to the invention, which has an au-ßenseitiges profile 1 and an inside profile 2.

In order to improve the thermal performance of the frame assembly, thermal insulating webs 5 may be formed between the outside profile 1 and the inside profile 2. The thermal insulating webs 5 are preferably made of plastic.

The outside profile 1 and the inside profile 2 are preferably made of aluminum or plastic.

Between the outside profile 1 and the inside profile 2, a disc assembly 3 is clamped. The disk arrangement 3 preferably has several disks arranged one behind the other. In particular, the disk arrangement 3 consists of two disks arranged one behind the other.

Between the discs of the disc assembly 3, a protective gas is preferably provided. As a result, the thermal performance of the disc assembly 3 is improved.

The frame assembly is disposed adjacent to an outer wall 4 or fixed to the outer wall 4. The outer wall 4 may for example belong to a building.

Of course, the outer wall 4 can have any conceivable shape and consist of any conceivable material. It is conceivable, for example, that the outer wall 4 consists of brickwork or brick made of wood. Also, the outer wall 4 may consist of concrete. The outer wall 4 may have a flat or contoured surface.

According to the invention, the frame arrangement is fastened to the outer wall 4 in such a way that a line of sight S extending perpendicular to the surface area of the pane arrangement 3 along the outer wall 4 does not intersect the profiles 1, 2. In other Words are the profiles 1, 2 viewed from the outside behind the outer wall 4 and thus hidden.

Seen from the outside, the profiles 1, 2 are thus not visually recognizable along the line of sight S, and sunlight incident along the line of sight S can not reach the profiles 1, 2.

As in Fig. 2a As shown, the frame assembly preferably has a thermal insulation 6 in the outside region of the outside profile 1. The thermal insulation 6 is arranged between the outer side profile 1 and the outer wall 4 or the outer side, in order to enable a connection between the outer side profile 1 and the outer wall 4 and on the other hand to improve the thermal performance of the frame assembly, since the heat transfer between the outside and the inside is reduced by the thermal insulation 6.

The thermal insulation 6 is preferably formed by a cavity 6a enclosed by the outside profile 1. The cavity 6a may preferably be filled by a protective gas or an insulating material.

Fig. 2b shows an embodiment in which in the region of the thermal insulation 6, a guide rail 7 is designed for guiding roller shutter elements.

As a result, on the one hand, the thermal insulation is ensured by the provision of cavities 6a adjoining the guide rail 7 and, on the other hand, it is possible that the guide rail 7 is not visible from the outside along the line of sight S.

Of course, it is conceivable that elements other than roller shutter elements are guided in the guide rail 7. For example, it is conceivable that an awning, a curtain or the like is guided in the guide rail 7.

Fig. 3 shows an embodiment in which a frame assembly is arranged in the region of a Wandverschneidung. In such a case, it is conceivable to arrange the frame arrangement only on one side of an outer wall 4a such that the frame arrangement is not visible when viewed from the outside, and on the side of the outer wall 4b, which is associated with the Wandverschneidung to use an ordinary frame assembly.
Fig. 4 shows an embodiment in which there is a spatial boundary 4c for the arrangement of the frame assembly.
In this case, the frame assembly is disposed adjacent to the boundary 4c and a transition element 8 is disposed between the outer wall 4 and the outer side profile 1.
The transition element 8 is arranged obliquely with respect to the line of sight S, so that seen from the outside not visible on the outer wall 4 profiles 1, 2 is visible, but only the transition element. 8
Between the transition element 8 and the outside profile 1, a cavity 8a is provided, which improves the thermal performance of the frame assembly.
As in the FIGS. 5 and 6 shown, a plurality of disc assemblies 3 may be provided, wherein the disc assemblies 3 relative to each other displaceable and / or may be arranged one behind the other. In these cases, the frame arrangement is designed such that the profiles 1, 2 of the frame arrangement adjoining the outer wall 4 are covered by the outer wall 4 when viewed from the outside.
The present invention is not limited to the exemplary embodiments shown in the figures, but results from a combination of all the features disclosed herein according to the present claims.
