Description

The present invention relates to sliding windows and sliding doors according to the preamble of patent claim 1.

Sash windows are described in this document. Since today many windows extend from the ceiling to the floor and thus such sliding windows are "actual doors", everything here applies to sliding windows and sliding doors with a butt stop The types of sliding windows presented are used where areas of unequal temperature are sealed off from each other.

Windows with a horizontally or vertically displaceable part have always been an alternative to one-sided hinged casement windows. While in the past the window was chosen rather small as the weak point of the isolation of a house, nan today wants large windows. Through double glazed and triple glazed insulating glass, it was possible to build slices with U-values that can be seen. In the interstices between the densely sealed glasses, a gas is introduced or evacuated to reduce heat transfer. The frames are made of wood, metal or plastic (with Metalivsrstärkung) produced. Thermal bridges, as they would be obvious in metal windows, are avoided by means of combined plastic-metal profiles. Between the all-round metal profiles sandwich-guided, insulating plastic frames are installed, which interrupt the thermal bridges.

However, the larger the window area is chosen, the more unwieldy becomes a one-sided hinged casement window. The natural desire for sliding windows has therefore become ever stronger. The sliding window also offers the advantage that in the open state no unwanted wings in the room or even protrudes from the facade. Especially with large windows, this disadvantage of casement windows is significant.

Now it is a fact that the tightness of a sliding window is more difficult to ensure. For casement windows, one-sided labyrinth seals, which are additionally equipped with seals, are generally available, which can be used to achieve very good insulation values.

One would like to build but also on the principle of sliding windows insulating windows, which with double or triple glazing are provided. The metal achieves the necessary stability with slim dimensions. The same principle is present in so-called plastic windows. Only that the plastic part of the visible part is made of plastic. The supporting metal frame lies within the plastic. Due to the insulating function of the wood, wooden frames are basically better insulated with sufficient strength and stability. Disadvantage of wooden windows is on the one hand the necessarily more massive design (the strength of metal is higher) and, of course, above all the more expensive maintenance. For industrial and commercial buildings, wooden frames are therefore normally not used. Metal or plastic frames are used.

For sliding windows, there is another problem: If you only blunt parts on top of each other, you can achieve a minimal isolation so as not to say you have no tightness. A complicated labyrinth for the purpose of isolation can be used for sliding windows only on three sides, namely the head profile, foot profile and the stop profile. In the offset profile, the surfaces of the profile part and the wing come together flat, which makes the good insulation very difficult. With the casement window, a clear movement of the movable window parts makes it possible to fit into a labyrinth between the casement and the window frame. In order to achieve the same effect on sliding windows, it is possible for three parts of the frame with an additional movement, perpendicular to the direction of displacement, to firmly strike and close three wing parts. The flat part of the offset profile is still not tight.

This problem is simply not taken into account in traditional sliding windows. It is sufficient with flat abutting stop planes at the offset profile and relatively poorly sealed labyrinth on the other three profile parts of the wing. This meets today's requirements of isolation, in particular the requirements in connection with Minergie standard in any way. Systems with their own rail for the wing are known. The part to be moved is raised so that it is easier to move on a so-called car. When closed, the wing sits down in a labyrinth while lowering. At the top he stays in the intended profile. At the stop frame, on which the wing strikes in the closed state, the wing by means provided for it during the weaning of the car, at the same time "pulled" into a labyrinth. Three sides of the wing are now reasonably well insulated. The flat superimposed in the closed state the center bar forming offset frame of the fixed and offset profile of the displaceable part but are in this system neither pressed together nor automatically tight. Here is only area on flat. Man manages with rubber seals and the like. However, a rubber seal is only satisfactory insulating when squeezed and thus all possibly still open slots are closed. Only then can values as good as those expected with conventional labyrinth seals be expected. The big drawback of such constructions is the depth of the window that occupies the sliding window parts.

With a "parallel sliding tilt system" resourceful architects tried to keep the depth of a sliding window as small as possible. Hardware companies designed a mechanism that can be operated with a lever. However, this single-lever mechanism is very expensive, it requires on the wing mechanics parts which have unsightly bulges result. In addition, these designs are far from easy to serve. When opening, the inexperienced user has the feeling that the wing falls on his head because it is first folded out of the profiles above. In addition, this construction require in the closed state on the fixed part of the window mounted protruding and unsightly foot rail.

The present invention now has the task to improve sliding windows and sliding doors of the type mentioned in such a way that without a complicated rail construction and complex mechanics a slim, easy to use and the insulation requirements of the Minergie standard sufficient sliding windows and sliding doors can be built.

This object is achieved sliding windows and sliding doors with a wing and a mechanism with the features of claim 1. Further inventive features will become apparent from the dependent claims and the advantages thereof are explained in the following description.

The figures represent possible embodiments, which will be explained in the following description.

To justify the use of sliding windows, various criteria must be met. Decisive are certainly the easy operation, the possibility of economic production and today in the sign of energy saving as well as the good insulation.

For ease of understanding, this document presents a simple, sandwich-metal-plastic version. Other materials such as wood, composites and combinations of materials are also used in practice.

Especially on the construction of the invention is the structure of the profiles. All profiles of the wing 2 and the window frame 40 must be reinforced in the right places to be able to wear the fittings safely. Likewise, the profiles must be secured by the center seal 8 secured between the window frame 40 and the wing 2 by the center seal 8 which is attached all around to the foot frame 41, the hooking frame 43, the head frame 42 and the offset frame 44. Fig. 8 ) withstand the resulting contact pressure on the entire circumference. This contact pressure arises because, in the closed state, ie the end position of the wing 2, the foot bolts 10, 10 'and the head bolts 20,20 'in the footpads 412,412' and the head switches 422,422 'are in a position that presses the wing 2 firmly against the window frame 40 ( Fig. 1 . 4 & 5 ). Extensive series of tests on the practical object with profiles and center seals that have been recomposed over and over again resulted in the necessary stiffness and strength of the profiles, which are decisive for the desired tightness and insulation.

Extremely great efforts have also been made to ensure with the center seal 8 between the offset profile 6 and the offset frame 44, the necessary tightness. The shape and hardness of the center seal had to be matched to all profiles and at the same time the optimum contact pressure. If the contact pressure is too great, the wing 2 can be brought into the closed position only with great force. If the contact pressure is too small, the window is not tight.

The groove in which the bolts are mounted runs all around in the foot profile 4, stop profile 5, head profile 3 and offset profile 6. In the open state of the wing 2, this groove with foot groove 12 and head groove 22 in the same plane. These grooves also have approximately the same width. The center seal 8 is in the open Condition free, so that the wing 2 on the carriage 14,14 'along the rail 413 can easily move.

The function for bringing the wing 2 into the correct position, that is to say from the point of view of the isolation, is described below. In the open state, the foot bolts 10 are located in the foot groove 12 formed by the foot frame 41 and the foot insert 411 (FIG. Fig. 3 ). The wheels 15 of the carriages 14 rest on the footrest 411 and / or on the rail 413. The head bolts 20 are located in the head groove 42 and head insert 421 formed head groove 22 (FIG. Fig. 2 ).

If the window is closed, the wing 2 is initially moved to the carriage 14, 14 'horizontally in the direction of the stop profile 5. The foot bolts 10, 10 'in the foot groove 12 and the head bolts 20, 20' in the head groove 22 (FIG. Fig. 2 & 3 ) guided. Shortly before closing, so about 3 - 5 cm before striking the stop profile 5 to the stop frame 43 reach the Fußbolzen 10,10 'in the Fußweichen 412,412' and the head pin 20,20 'in the Kopfweichen 422,422' ( Fig. 4 & 5 ). At the same position of the wings 2, the engagement of the hooks 30, 30 'begins in the locking shafts 31, 31' ( Fig. 6 & 7 ). The hooks 30, 30 'are attached to the wing 2 Transmission 32 vertically displaceable. If the hooks 30,30 'detect the closing shafts 31,31' and then moved vertically down, this occupancy pulls the closing shafts 31,31 'in the Schliessführungen 33,33' and thus the wing 2 by means of head bolts 20,20 'in the head switches 422, 422 'and the foot bolts 10, 10' into the foot switches 412, 412 '.

In continuation of the foot groove 12 in the foot frame 41 and the head groove 22 in the head frame 42, the foot bolts 10,10 'move into the foot switches 412,412' and the head bolts 20,20 'in the head switches 422,422'. Upon further movement of the wing 2 towards the stop frame 43, the switches in about 45 ° deviation from the previous movement the wing 2 transverse to the window frame 40. In the end position of the wing 2 is closed ( Fig. 6 ) and is pressed against the window frame 40 all around extending center seal 8 ( Fig8 ). The wheels 15 of the carriages 14,14 'move laterally during this process on their axes about the distance provided by the foot switch 412 and the head switch 422 and necessary, relative to the foot groove 12, head groove 22 and rail 413. The hooks 30,30' move during the closing process with the wing 2 also relative to the stop frame 43 the closing shafts 31,31 'also the same distance laterally.

In the closed state scratches the all-round, pressed center seal between the window frame 40 and 2 wings that the wing 2 with the window frame 40 insulation is tight.

For receiving the head pin 20,20 'and foot bolt 10,10' is described above on the wing 2, only one groove required. This groove can, but need not, for the inclusion of the hook 30,30 'and the transmission 32 use find. Such a design makes production less expensive. For receiving the car 14,14 ', this groove can also be used. Depending on their dimension, however, their own possibly additional cut-out is necessary.
