DE2353186B2 - Fixed metal frame for sliding windows or sliding doors - Google Patents

Description

The invention relates to a fixed metal frame for sliding windows or sliding doors with running and guide rails as well as insulating pieces that are between Outer and inner profiles and the basic profile of the metal frame are arranged.

In window and door structures made of metal, it is already well known to interrupt the insulation in the Provide frame and sash in order to create cold or heat bridges when the sash is in the closed position between the outer zone, also known as the cold zone, and the inner zone (warm zone). It is also no longer new (see DT-Gbm 70 18 201), with fixed metal frames for sliding windows or sliding doors of the type described above to arrange insulating interruptions so that the Outer and inner profiles are separated from each other and from the basic profile. This can be done in the transverse direction of the fixed frame achieve a certain isolation, in the longitudinal direction of the lower or upper However, the horizontal frame leg is a transition between the wing in the area of the center joint Cold and warm zones possible.

It is the object of the invention to design a fixed window frame of the specified type in such a way that that it has improved insulation both in the transverse direction of the lower and upper frame legs as well as in the longitudinal direction of the frame legs heat or cold bridges in the area of the central joint of the Avoids wing.

The object is achieved according to the invention in that the running and guide rails are made of plastic, that the lower and the upper legs of the frame have U-shaped center rails, which under Interposition of a plastic spacer attached to the base profile of the frame, that the central rails are interrupted by an insulating piece made of plastic in the area of the central joint of the sliding sash are that a tavern! the middle sheer has a horizontal bend that engages with a shoulder in the inner profile or the outer profile, wherein the middle rail is installed so that the bend in the area in which the outer Sliding sash is in the closed state, inwards and in the area of the inner sliding sash is directed outside.

The technical progress of the construction according to the invention is that in the area of the central joint the sash and a complete separation in the area of the lower and upper horizontal frame between the inner and outer zone.

The invention is based on the following exemplary embodiment, which is a double-leaf lift-and-slide door concerns in the closed position, explained in more detail. It shows F i g. 1 the door schematically in elevation, F i g. 2 shows a horizontal section along line II-II in

a vertical section along line IH-III in

Fig. 1,

F i g. 4 is a perspective view of a corresponding section from the lower horizontal leg of the stationary one Metal frame, with the parts being moved apart after a vertical cut and

F i g. 5 shows a vertical section through the insulating piece of the lower horizontal frame leg that interrupts the center rail.
The F i g. 1 shows schematically the outer sliding sash 1 (with metal frame Γ), the inner sliding sash 2 (with metal frame 2 ') and the fixed frame 3 of a lift-and-slide door. The lower horizontal leg of the frame 3 is labeled 3 ', the upper horizontal frame leg with 3 ".

The F i g. 2 shows a horizontal section through the outer sliding sash 1 and frames Γ or 2 'on the central joint.

From Fig. 3 clearly shows that the lower and upper horizontal frame legs 3 'and 3 "are analogous are trained.

The F i g. 4 shows in perspective the corresponding lower horizontal frame leg 3 'at the central joint. For a better overview, the parts have been moved apart after a vertical cut. Since according to

5 »F i g. 3 the lower and the upper horizontal frame legs 3 'and 3 "are designed in principle analogously, the description can be limited to the lower frame leg 3 '. In Fig. 3, however, are for the Corresponding parts of the upper horizontal Rah-SS Menschenkels 3 "have the same reference numbers.

The lower horizontal frame leg 3 ′ has a basic profile 4 and an outer 5 and an inner profile 6 on. A U-shaped center rail 7 lies on a spacer 8 made of plastic and is in use a continuous rail 9 attached to the base profile 4. The U-shaped center rail 7 is in the area of the Central joint of the sliding sash 1, 2 interrupted by an insulating piece 10 made of plastic, which in vertical section the lower frame leg 3 'essentially

⁶ fields (see Fig. 5). The insulating piece 10 is also attached to the base profile 4 using the rail 9. With regard to its length in the profile direction, the insulating piece 10 is the dimension of the

Sliding sash frame Γ or 2 'adapted to the central joint

The arrangement of the insulating piece 10 in the area of the central joint of the sliding sash 1, 2 prevents that in the longitudinal direction of the lower or upper horizontal frame leg 3 'or 3 "heat or cold bridges appear.

Starting from the insulating piece 10, a shoulder 11 provided with an attachment engages in the area of the outer sliding sash 1 horizontal bend 12 of a vertical leg 13 of the U-shaped center rail 7 in the inner profile 6 a; while in the area of the inner sliding sash 2 the horizontal bend 12 into the

Outside professional! 5 intervenes. The U-shaped middle rail 7 is according to the arrangement of the outer or inner sliding sash 1 or 2 and thus rotated according to the course of the temperature zones. Through the The cut-open representation of the lower horizontal frame leg 3 'shows the change in the arrangement the center rail 7 particularly clearly.

Continuous running rails 14 for the sliding leaves 1, 2 are in corresponding spaces between U-shaped central rail 7 or insulating piece 10 and the outer 5 and the inner profile 6 are used. The Running rails 14 correspond to the guide rails 14 'in the upper horizontal frame leg 3 ″.
