EP2735685A2 - Window, door or facade element with a glass bridge with integrated light - Google Patents

Abstract

The window (1), door or facade element comprises a frame (2,3) made of profiles (4,5), which receive a surface element (18). The profiles comprise a glazing rebate (17), in which one or multiple glass bridges (49) made of plastic material or light metal material are arranged. The glass bridge comprises an illuminant (43). The illuminant is located in a non-visible area of the window, the door or facade element after assembling the glass bridge in the frame profile. The main beam direction of the light of the illuminant runs parallel to the outer surface of the surface element.

Description

The present invention relates to a window, a door or a facade element according to the preamble of claim 1.

Such elements are known in the art.

In addition, bulbs of various types and sizes arranged on or near the window constructions to illuminate the panel elements (e.g., patch lamps) are known.

The term "emdelight glass" glass panes are known, which are also referred to as light glass. Here, LED lamps are mounted on the edge of the window, which emit their light by refraction in the glass on the disc surfaces again.

However, the known products are relatively expensive and difficult to assemble. In the known light glass, the disk edges must be processed consuming. Since the load transfer of the glasses / discs also takes place at the edge of the disc, constructive problems arise here. In general, electricians must make connections in the window constructions, so that for the installation of the window constructions and for the surface elements, the participation of professionals from different disciplines is required and therefore the installation of such products is correspondingly expensive.

The invention is therefore based on the object to provide a window, door or facade element, which overcomes the aforementioned disadvantages.

The invention solves the problem in that the at least one glass bridge has at least one light source.

The invention is therefore based on the idea of a glass bridge for blocking a surface element, such as a glass element. an insulating glass pane of a window, a door or a facade element for buildings to provide in a frame having at least one light source.

A particularly advantageous embodiment of the glass bridge according to the invention is obtained when LEDs, in particular SMD LEDs are used as the light source and the bulbs are integrated into the glass bridge so that they are not visible in the mounted state of the glass bridge and thus protected from environmental influences or damage ,

In order to further improve the optical properties of a glass bridge according to the invention in a particularly advantageous manner, a gel reservoir may be present in the glass bridge, which bursts when the glass bridge is mounted, so that the gel is deposited between the illuminant and the surface element or flows there. Thereby, the refractive index jump between air and e.g. reduced or avoided the glass of the surface element.

The invention further provides the glass bridge (as a bridge for a surface element, which in particular but not necessarily consists of glass) of claim 17.

Further advantageous embodiments of the window, door or facade element can be found in the dependent claims.

In Fig. 1 a basic structure of a window 1 with a glass bridge 49 is shown with integrated bulb 43.

Hereinafter, a window 1 will be described for the sake of simplicity. However, this is only to be understood as an example. In principle, the invention can also be used on correspondingly designed doors or facade elements.

The window 1 has a frame 2 and a sash 3. The frames 2, 3 are formed from frame profiles 4 or sash profiles 5. For this purpose, the profiles 4, 5 are cut to length according to the requirements and assembled into corresponding frames 2, 3, so that the frames 2, 3 have a closed circumferential contour line from the corresponding frame profiles 4, 5.

The window frame profile 4 in each case has a separate inner shell 6, which is assigned to an interior of a building, and a separate outer shell 7, which as a rule is assigned to the weather-exposed side of a building. The inner shell 6 and the outer shell 7 each have at least one cavity 8, 9, which is in each case crossed by a plurality of struts 10.

The inner shell 6 and the outer shell 7 are each in the in Fig. 1 illustrated example made of a light metal by extrusion. However, the frame profile 4 can in principle also be made of other suitable materials for window profiles-such as plastic or wood-by suitably suitable manufacturing methods-such as extrusion or a machining process.

The inner shell 6 and the outer shell 7 are positively connected to one another by a first insulating strip 11 and preferably a second insulating strip 12. The first insulating strip 11 and the second insulating strip 12 are preferably made of a plastic material, e.g. produced by extrusion. The first insulating strip 11 and the second insulating strip 12 are each held in two grooves 13, 14, and 15, 16, which are arranged in the inner shell 6 and in the outer shell 7, respectively.

Between the first insulating strip 11 and the second insulating strip 12, a cavity 20 is formed, which has a heat insulation foam profile 21 to improve the thermal insulation properties of the frame profile 4, which is positioned and held by appropriate geometric expression of the first insulating strip 11. With the first insulating strip 11, a seal 19 is connected by a snap connection 22.

Overall, the frame profile 4 here has a basic cross section, which can be described by an "L".

The sash profile 5 advantageously also has a separate inner shell 23, which is assigned to an interior of a building, and a separate outer shell 24, which is generally assigned to the weather-exposed side of a building. The inner shell 23 and the outer shell 24 each have at least one cavity 25, 26, which is traversed by a plurality of struts 27. The inner shell 23 and the outer shell 24 are each in the in Fig. 1 illustrated example made of a light metal by extrusion. The casement profile 5 can, however, in principle also be made of other suitable materials for window profiles-such as, for example, plastic or wood-by means of suitably suitable production methods, such as, for example, extrusion or a cutting process.

The inner shell 23 and the outer shell 24 are advantageously in turn positively connected by a first insulating strip 28 and preferably a second insulating strip 29 with each other. The first insulating strip 28 and the second insulating strip 29 are preferably made of a plastic material by, for example, extrusion. The first insulating strip 28 and the second insulating strip 29 are respectively in two grooves 30, 31, and 32, 33, which are arranged in the inner shell 23 and in the outer shell 24, held.

By joining the inner shell 23, the outer shell 24 and the two insulating strips 28, 29 a glass fold 17 is formed, in which a surface element 18, such as e.g. an insulating glass with Dreischeibigem structure, is held. The second insulating strip 29 further forms a sealing stop 34. Accordingly, a cavity 35 advantageously forms between the first insulating strip 28 and the second insulating strip 29, which has a heat insulation foam profile 36 to improve the thermal insulation properties of the sash profile 5, which is positioned and held by appropriate geometric expression of the second insulating strip 29.

Overall, the casement profile 5 here has a basic cross-section which can be described by a "Z".

The frame profile 4 and the sash profile 5 form a folded space 37 in the closed state of the window 1. Furthermore, the frame profile 4 and the sash profile 5 have a plurality of T-shaped grooves which are arranged in the respective inner shell 6, 23 or outer shell 7, 24 are. The groove 38 in the inner shell 23 of the sash profile 5 receives a seal 39 which seals a gap 40 between the inner shell 23 of the sash profile 5 and the inner shell 6 of the frame profile 4. By this seal 39 of the rebate space 37 is sealed against the room side of the window 1.

A further sealing plane is located in the rebate space 37 between the two heat-insulating foam profiles 21 and 36. The seals 19 and the sealing stop 34 advantageously seal the weather-exposed outside of the window 1 against the rebate space 37.

Another groove 41 in the region of the outer shell 24 of the sash profile 5 receives an outer sealing profile 42, with which the outer gap between the surface element 18 and outer shell 24 of the sash profile 5 is sealed. The outside sealing profile 42 is designed as a so-called plant seal.

In a further groove 44 in the inner shell 23 of the sash profile 5 engages a Glashalteleiste 45, which is a part of the inner shell 23 of the sash profile 5. The glass retaining strip 45 is provided with a room-side sealing profile 46, which seals the space-side gap between the surface element 18 and glass retaining strip 45. The room-side sealing profile 46 is designed as an advantageous plug-in seal and has a groove 47 through which the room-side sealing profile 46 is supported on a web 48 of the glass retaining strip 45.

The surface element 18, in Fig. 1 exemplified executed as insulating glass with dreischeigigem structure, is based on a glass bridge 49, which is arranged in the glass fold 17 of the sash profile 5. The glass bridge 49 rests on the first insulating strip 11 or on webs 50, 51 of the sash frame profile 5. At least one luminous means 43 of the glass bridge 49 according to the invention with integrated illuminant 43 is embedded in the glass bridge 49 in a recess 52 and arranged such that its main radiation direction is set on a surface element 18 designed as an insulating glass pane taking into account the refractive index of window glass with respect to air by exceeding the critical angle of total reflection preferably gives a total reflection of the light and thereby a substantial part or even the entire surface of the surface element 18 is illuminated.

The recess 52 is filled with a transparent gel 53 after insertion of the luminous means 43, so that the luminous means 43 is completely enclosed by the gel 53. By reaction with the surrounding air, the gel 53 forms a thin skin, which is destroyed during the assembly of the surface element 18 on the glass bridge 49. Alternatively, the gel reservoir may advantageously also be protected against damage by an adhesive strip (not shown). The adhesive strip is accordingly removed or removed from the gel reservoir before assembly. The gel 53 advantageously flows or deposits itself between the luminous means 43 and the surface element 18, in particular to the central glass pane 54, if-as shown here by way of example-an insulating glass pane with a three-disc structure is used as the surface element 18. As a result, the refractive index jump between air and, for example, the glass of the surface element 18 is reduced or avoided.

Alternatively, the lighting means 43 may be arranged to light the outer glass sheet or the inner glass sheet of insulating glass or a combination of glass sheets or all glass sheets of an insulating glass panel, as far as the sheet member 18 as shown in FIG Fig. 1 exemplified Isolierglas is selected with multi-disc structure.

Due to the selected arrangement of the illuminant 43 in the glass bridge 49, the illuminant 43 is advantageously protected against environmental influences but also against damage and, moreover, is not visible from the outside.

The glass bridge 49 is advantageously preferably made of a plastic material or, based on its cross-section, entirely or partially made of an electrically conductive plastic material. The preparation of the glass bridge 49 from a completely or partially electrically conductive plastic material allows a particularly advantageous and simple electrical power supply of the lamp 43.

Alternatively, the glass bridge 49 can also be made of a light metal material, e.g. Aluminum be produced by extrusion.

Preferably, the lighting means 43 is realized by an LED chain which extends over the entire length of the glass bridge 49. Particularly preferred as LEDs SMD LEDs are provided. As a result, the lighting means 43 can be arranged over the entire length of the glass bridge 49. In principle, however, other suitable bulbs 43 can be used.

By arranging discrete lighting means 43 -such as for example LEDs -with constant spacing from one another over the entire length of the glass bridge 49, or at the periphery of the surface element 18, when two glass bridges per side of the surface element 18 are installed, the quantity of lighting means can be varied 43 per unit length advantageously different local light intensities are generated on the surface element 18.

Alternatively, it is also possible to arrange the lighting means 43 at a variable distance from one another over the entire length of the glass bridge.

Moreover, it is also possible to arrange LEDs with different colors of light or to use RGB SMD LEDs, so that the light colors are e.g. can be changed by a control unit and thus dynamic lighting effects on the surface element 18 can be realized.

According to the invention, the size of the LEDs is at most 6 × 6 mm, preferably 5 × 5 mm, preferably 4 × 4 mm and particularly preferably 3 × 3.5 mm.

The use of a glass bridge 49 according to the invention with illuminant 43 in a casement 3 is to be understood merely as an example. In principle, the invention can also be used for a window 1 without casement, that is to say a fixed frame, such as the frame 2, in which the surface element and the element provided with the luminous element are then inserted.

In Fig. 2 a glass bridge 49 according to the invention with integrated light source 43 is shown. The glass bridge 49 according to the invention advantageously has a continuous, meandering recess 52 extending over the entire length of the glass bridge 49. The meandering geometry of the recess 52 is formed by equidistantly spaced projections 57, 58 which project into the recess 52 on the side of the flank and which serve for reliable load transfer of the surface element 18. In addition, a pre-assembled arrangement of a plurality of light-emitting means 43-for example LEDs-including a conductor 55 can be introduced into the recess 52. The assembly effort for introducing the bulbs 43 in the recess 52 in the glass bridge 49 is thereby reduced. The attachment of pre-assembled lighting means 43 incl. The conductor 55 at the bottom of the recess 52 of the glass bridge 49 can be made cohesively, for example by gluing or form-fitting by clipping or by a snap connection.

The conductor 55 is advantageously led out laterally from the recess 52 and forms in each case a cable connection 56 or plug connection, with which the conductor 55 is provided with a connecting cable (not shown) or with a plug can be connected via the further glass bridges 49 with integrated lighting means 43.

In Fig. 3 In particular, the edge region of a glass bridge 49 according to the invention with integrated illuminant 43 is shown. The remaining space of the recess 52 after insertion of the pre-assembled bulbs 43 -herein by way of example LEDs-including the conductor 55 on the bottom of the recess 52 is filled with a gel 53. so that the lighting means 43 is completely enclosed by the gel 53. By reaction with the surrounding air, the gel 53 forms a thin skin, which is destroyed during the assembly of the surface element 18 on the glass bridge 49. Alternatively, the gel reservoir may also be protected from damage by an adhesive strip (not shown). The adhesive strip is accordingly removed or removed from the gel reservoir before assembly. The gel 53 thereby flows or settles between the lighting means 43 and the surface element 18, in particular to the central glass pane 54, if-as shown here by way of example-an insulating glass pane having an advantageous three-disc construction is used as the surface element 18. As a result, the refractive index jump between air and, for example, the glass of the surface element 18 is reduced or avoided.

In Fig. 4 is the glass bridge 49 and over the entire length of the glass bridge 49 advantageously extending, meandering meandering 52 well recognizable. The meandering geometry of the recess 52 is formed by equidistantly spaced projections 57, 58 which project into the recess 52 on the side of the flank and which serve for the secure support of the surface element 18. In addition, a pre-assembled arrangement of a plurality of light-emitting means 43-for example LEDs-including the conductor 55 can be introduced into the recess 52. The attachment of the prefabricated bulbs 43 incl. The conductor 55 at the bottom of the recess 52 of the glass bridge 49 can be cohesively, eg by gluing or form-fitting by clipping or by a snap connection.

The conductor 55 is advantageously led out laterally from the recess 52 and forms in each case a cable connection 56 or plug connection, with which the conductor 55 is provided with a connecting cable (not shown) or with a plug can be connected via the further glass bridges 49 with integrated lighting means 43.

Preference is given to use as surface elements 18 insulating glass panes, which are provided with reflective nanoparticles or scattering particles. As a result, the lighting effects are advantageously improved or targeted location.
