CZ303096A3 - Hollow plastic-made profile for windows or doors - Google Patents

Abstract

The aperture frame (2) arranged on the outside on the frame profile (1) in the closed state of the window or door engages behind a lug formation (10) on the window pane or door panel frame (3). The lug formation has a flank area (11), which runs parallel to a formed-in area (12) on the aperture frame. The formed-in area on the aperture frame is formed U-fashion with outwardly widened arms (13.1). The freely extending face edge of the aperture frame locates on the pane or panel frame. There is a groove (14) in the face edge, in which a lip seal (15) is arranged. The lip seal engages in a trough or groove in the window pane or door panel frame.

Hollow plastic profile for windows or doors

The invention relates to a hollow plastic profile for windows or doors, which consists of a frame profile with a blind frame; _{in which is pivotally or hingedly arranged window leaf frame nebodveří r

BACKGROUND OF THE INVENTION.

In window or door designs that open either inwards or outwards and which are known in the art, so-called blind frames are used to achieve the overlap in the closed state, either on the frame profile or on the sash frame. The blind frame overlaps the gap between the frame profile and the sash frame, thereby achieving a tight connection around the perimeter of the sash, when the window or door is closed, between the frame profile and the sash frame. Particularly in the case of a window or door which can open inwards, the blind frame profile frame abuts the window or door frame from the outside.

These known hollow plastic profiles have the problem that the hollow plastic profiles thus made are not sufficiently secure in the sense that the lever tool can easily penetrate under the blind frame, thereby. It penetrates into the slot between the frame profile and the wing frame. This is facilitated by ^R 'are resilient plastics material .. If the lever and instrument enters "until the slot can be extended lever thus obtained also wrenching casement or door inwards' of sheet metal anchoring elements.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to further improve the hollow plastic profile so as to achieve a substantially higher burglary safety.

SUMMARY OF THE INVENTION

This object is solved and the drawbacks of the known hollow plastic profiles largely eliminate an embodiment of a hollow plastic profile, which consists of a frame profile with a blind frame, in which the sash or window frame according to the invention is pivotally pivotally arranged. The blind frame, which is shaped on the outside of the frame profile, in the closed state of the window or door, fits over the protruding profile which is shaped on the frame of the window or door leaf. Due to this labyrinth shaping in the overlapping region of the blind frame and the sash frame, it is advantageous to make it particularly difficult or completely impossible for a tool to penetrate over the entire circumference of the hollow plastic profile. The thus formed tooth-like connection between the frame profile and the sash frame thus constitutes an additional blocking between the window or door frame elements with this hollow plastic profile. It is therefore no longer possible to simply pry off the blind frame on the frame profile, since the blocking protruding profile on the sash frame blocks the access path for the mounted pry tool.

For this purpose, the projecting profile has a side wall which extends parallel to the abutment region which is formed on the blind frame. This results in an outwardly facing surface which is an obstacle to the penetration of the prying tool. · A. ·

The abutment region on the blind frame is preferably U-shaped

with outwardly diverging shoulders. The recess thus formed on the blind frame overlaps the projecting profile with its outer diverging arm such that, as already mentioned, this arm extends parallel to the side wall of the projecting profile.

A further advantageous improvement is that the free protruding leading edge of the blind frame abuts the sash frame.

For a tight connection between the plane of the sash frame and the blind frame

1, a groove is formed in the front edge of the blind frame in which the flap seal is arranged. This seal fits in chíopňové e TWR hi ff ·· -rtK * u * · »· τ - - <- fr κ · - · -RR -» _B close to the plane of the sash.

Λ t

> To reduce the gap at the sealing point to make it impossible to penetrate the tool, the flap seal can interfere with a recess or groove in the window sash ^: or door, so that the blind frame basically rests on the sash.

A particularly preferred embodiment of the hollow plastic profile according to the invention consists in that the blind frame and the protruding profile are designed as chambers in which the stiffeners are individually embedded. This embodiment results in the walls of the hollow plastic profile being reinforced. , which further makes it difficult to penetrate the prying tool.

In another embodiment of the hollow plastic profile according to the invention, the sash of the window or door is provided with a groove in the shape

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a cross-section of a hollow plastic profile for a window or door, which consists of a frame profile 1 with a blind frame 2, in which the sash frame 1 of the window or door is arranged in a pivotable and / or hinged manner. The frame profile 1 is arranged in a "not shown" opening in the masonry. In the sash frame 3, between the two sealing strips 4.1, 4.2- there is a single-pane or double-glass pane indicated in cross-section. Frame profile. 1 and the wing frame 3. they consist of plastic profiles with chambers 6, in which stiffeners 7 with a square, rectangular or U-shaped cross-section can be arranged.

- .. the door .. is created. the hollow edge of the .8 which is provided. The seal 9 and in a closed condition abut against the frame profile from the inside

According to the invention, in the closed state of the window or door from the inside, under the blind frame 2, which is formed, on the outside of the frame profile 1, the projecting profile 10, which is formed on the window frame 3 of the window or door. This protruding profile 10 has a side wall 11 which extends parallel to the abutment region 12 of the blind frame 2. Due to this labyrinth engagement, a tool (not shown) which is not shown, for example, by which the window or door is to be pry open, is considerably more difficult or impossible. The seating area 12, which is formed on the blind frame 2, has the shape of a letter U with outwardly extending arms 13.1 and 13.2. As can be seen from FIG - * rf- 1 | +. > I * * ». The front edge of the blind frame 2 to the frame 3'wings. In this front edge, a groove 14 is formed in which the flap seal 15 is received. As can be seen from the partial section shown, the blind frame 2 and the protruding profile 10 are also hollow profiles. which may be provided with reinforcements 2- ´ '; '

In another embodiment ,, as shown in FIG. 2, the frame 3 sash window or door with a groove '16 U-shaped, into which, in. The closed state of the window or door fits,' J H ¹ · 17th edge strips which is formed on the blind frame 2.

. l.l ·

In the closed state, the edge strip 17 fits into the U-shaped groove 16 as a latch, so that a positive connection between the blind frame 2 and the sash 3 is achieved. The U-shaped groove 16 is formed in the outer wall 18 of the window casing 3 of the sash, and the side walls 19.1 and 19.2 of the U-shaped groove 16 may have a straight or arcuate cross-section. in particular from FIG. 2, openings are formed in the walls of the chambers 6 of the frame, sash and wing frame 3. 20. which allow indirect circulation ventilation between the frame profile 1 and the outwardly-extending window or door leaf frame 3.
