A frame construction essentially comprises a frame with a surface element and may for example be part of a facade construction, a window or a door. For example, a sash of a door or a window comprises a frame with a pane, usually insulating glass, as a surface element. The casement is correspondingly pivotally received in a frame. In a facade construction frames are made of posts and bars or element frames in which surface elements, usually also discs, are added. The facade construction can be attached to a house wall.

The requirement for the so-called vapor pressure equalization will be explained in more detail using the example of a facade construction.

The vapor pressure equalization (ventilation, drainage) of a facade construction, such as a mullion-transom façade or an elemented facade, is usually carried out by an antechamber. This z. B. conducted in a mullion-transom façade moisture in Glasfalz via openings in the pressure bar in an antechamber and discharged from here to the outside. The opening from the antechamber to the outside is usually deeper than the opening in the pressure strip, so that no pressed by wind in the first opening rainwater can penetrate into the glazing rebate.

For elemental facades, the ventilation takes place, for example, via an antechamber of the frame profile either via an opening on the weathered side of the profile (path 1) or concealed (path 2). In the latter inlet and outlet openings are laterally offset from one another or offset in height.

In both cases, the profiles must be machined, in particular holes and / or milling be made, resulting in a considerable amount of work.

In the Fig. 1 and 2 First, a frame assembly, in particular a facade construction, shown in the prior art.

The vapor pressure equalization (ventilation, drainage) of a facade construction, such as a mullion-transom façade or an elemented facade, is usually carried out by an antechamber. This z. B. in a mullion-transom facade moisture on the rebate A via openings in the pressure bar B in the prechamber C and discharged from here through an opening (not shown) between two cover profiles to the outside. The aforementioned opening is usually deeper than the opening in the pressure strip B, so that no pressed by wind in the first opening rainwater can penetrate into the glazing rebate A.

In the case of elemented facades, the ventilation takes place, for example, either via an opening on the weathered side of the profile (Way 1 - Fig. 2a ) or concealed over an antechamber of the frame profile (way 2 - Fig. 2b ). Here, inlet and outlet openings are laterally offset from each other.

In the following, first, the sealing molding according to the invention and its possible use in a frame assembly will be explained in more detail.

The sealing molding 1 is basically a seal, which is at least partially made of a plastic, in particular EPDM (ethylene-propylene-diene rubber), silicone, etc.

The sealing molding 1 is preferably elongated and has a first contact surface 10 and a second contact surface 11. The first contact surface 10 is for abutment against a surface element 2 and the second contact surface 11 is in principle intended for abutment or attachment to a frame 3. The sealing molding 1 further has two end faces 12 and a first side face 13 and a second side face 14.

Furthermore, the generally elongate sealing molding has a channel 15 with two openings 16, 17, wherein the channel 15 extends in the longitudinal direction of the sealing molding 1. The openings 16, 17 are provided neither in the contact surfaces 10, 11, nor in the end faces 12, but in the remaining surfaces, ie the side surfaces 13, 14. The channel 15 extends in the longitudinal direction of the sealing molding 1, so that the openings 16, 17 are located at different heights and on different sides on the seal molding 1. Accordingly, a first opening 16 in the first side wall 13 and a second opening 17 in the second side wall 14 are provided.

The example of a gasket molding, as in the Fig. 3 to 5 is shown, the gasket molding according to the invention will be explained in more detail.

The sealing molding 1 may for example be L-shaped and have a first leg 18 and a second leg 19. The legs 18, 19 are preferably aligned at an angle of 90 ° to each other. Preferably, the first leg 18 is longer than the second leg 19. The channel 15 and its openings 16, 17 are provided in the first leg 18. The channel 15 extends in the longitudinal direction of the first leg 18. The second leg 19 serves essentially only for sealing purposes or for fitting the sealing molding 1 into a corner of a corresponding rectangular frame 3.

In the preferred embodiment of the sealing molding 1 shown here, starting from the free end of the first leg 18 in the direction of the second leg 19, first the first opening 16 in the first side surface 13 and further in the direction of the second leg 19, the second opening 17 in the second side surface 14 is arranged.

Using a window, in particular a fixed glazing window, comprising a frame 3 and a surface element 2 accommodated in the frame 3, in particular an insulating glass pane, the use of a gasket molding 1 according to the invention is explained in more detail.

In the Fig. 6 to 8 is the use of the sealing moldings 1 according to the invention in a likewise inventive frame arrangement for the application of a window, in particular a fixed glazing window, shown in more detail. An insert in a window sash, such as a window or a door is readily conceivable.

The frame 3 essentially comprises four profile arrangements 31, which are assembled into a rectangular frame. Each profile arrangement may for example have two profiles 311, 312 and an insulating profile arranged between the profiles or a plurality of insulating webs 313. In essence, the profile arrangements 31 form in cross section an approximately U-shaped receiving region 32, which is also referred to as a glass fold, with a base 321 and a first leg 322 and a second leg 323. However, the term glass fold 32 used below is not intended to be limiting be such that only surface elements 2 made of glass could be used here. The formulations base 321, first leg 322 and second leg 323 are intended essentially to explain the geometric conditions, while the two profiles 311, 312 and the insulating webs 313 represent the components used. It is not mandatory that the legs must be rectangular. Depending on the requirements of the frame, different configurations are conceivable here.

In an inserted state of the surface element 2, an edge region of the surface element is received in the glass rebate 32. At least between a leg 322 and the surface element 2, an inventive seal molding 1 is attached. Between the other leg 323 and the surface element 2, a conventional seal 4, but also an inventive seal molding 1 may be attached. In essence, a conventional seal 4, at least in sections, is replaced by the seal molding 1 according to the invention.

The channel 15 creates a connection between the glazing rebate 32 and the environment, which is suitable for equalizing the vapor pressure (ventilation, drainage). The openings 16, 17 are in a common mounting position of the frame assembly, in particular of the window or the door, at different heights, in particular, the first opening 16, which is usually aligned to Glasfalz, higher than the second opening, in the Usually facing the outside air, arranged so that the unintentional penetration of water into the glass rebate 32 can be prevented.

As already indicated above, the gasket molding 1 according to the invention can also be used, for example, in facade constructions. Also, this application is briefly below, in particular based on Fig. 9 to 11 be sketched.

A facade construction essentially comprises a number of frame arrangements according to the invention, in particular frames 3, in each of which surface elements 2 are accommodated.

The frames 3 are essentially formed of posts and bars which are attached to a house facade. The posts and bars are preferably aligned at a right angle to each other. The posts and bars are also essentially profile arrangements 31. The frames 3 can also be formed by individual so-called element frames, which then form an element facade accordingly.

Both the posts, as well as the bars or the element frames usually comprise a first profile 311, a second profile 312 and at least one provided between the profiles insulating profile 313. The insulating profile may also consist of two or more insulating strips.

The first profile 311 may be configured in one piece or in several parts. In the present case, the first profile is designed in several parts.

The second profile 312 is designed in one piece in the present case, but may also be designed in several parts. Essentially, the second profile has a central hollow profile from which two booms exit.

The insulating strips 313 are arranged between the first profile 311 and the second profile 312. Overall, results from the aforementioned profiles and insulating strips in cross-section about a double-T-shaped profile arrangement, in particular posts or bars, which form a glazing rebate on both sides.

The structural design forms by the truss-like profile arrangements 31, in particular the posts (vertical) and bars (horizontal), a number of preferably rectangular frame 3, in each of which a surface element 2, preferably a disc is added. In essence, the facade construction thus comprises a number of frame arrangements according to the invention.

For the attachment of the surface elements 2 form the profile arrangements, in particular the posts and bars, Glasfalze for receiving an edge region of the surface elements. Essentially, the comments above on the windows and doors can be referenced.

In a sectional view of a post, it can be seen that the glass rebate 32 is approximately U-shaped and two glass folds are provided in the post. In essence, the first glazing rebate 32 is formed by an edge region of the first profile 311, the first insulating strip 313 and the second profile 312. The second glazing rebate 32 'is essentially formed by an edge region of the first profile, the second insulating strip 313' and the second profile 312. The bolt can be constructed very similar and, for example, also form two Glasfalze.

The surface element 2 is used with an edge region in the glazing rebate. According to the invention, it is provided that at least one gasket molding 1 is inserted between the glazing rebate 32 and the surface element 2. The channel 15 creates a connection between the glazing rebate 32 and the environment, which is suitable for equalizing the vapor pressure (ventilation, drainage). The openings 16, 17 are in a conventional mounting position of the frame assembly, in particular the structural structure, at different heights, in particular the first opening 16 is arranged to glass rebate 32 higher than the second opening 17 to the outside air, so that the inadvertent ingress of water in the Glasfalz 32 can be prevented.

The advantages or functional features of the sealing molding according to the invention or of the frame according to the invention produced therefrom with surface elements can be described in particular as follows.

In the frame arrangements according to the invention, the cross-section of the outer glazing gasket is used to define a height of rise of penetrating water with the gasket molding 1 according to the invention. The seal molding 1 off Plastic, preferably EPDM or silicone, is preferably introduced into the joint between the frame and the glass sheets, and the subsequent joint area is preferably closed with normal glazing profiles.

The gasket molding 1 according to the invention is preferably used in the vertically extending sealing joint and has the first opening 16 in the glass rebate 32 and the second opening 17 to the outside air, which are both connected to the channel 15. Due to the height offset between the inlet and outlet opening is avoided that rainwater is driven by wind pressure in the glass rebate 32.

In addition, the molded part can be shaped such that "noses" at the ends 121 engage in the openings of the subsequent glazing profile and create a clean transition between the molded part and the glazing gasket.

The profiles are preferably made of aluminum, the insulating strips preferably made of plastic.

It may, in addition to the above outlined applications of the frame arrangements in windows, doors and facades also other applications come into question.
