Description

The invention relates to a pitched roof window formed as a swing window, in particular pitched roof apartment windows, according to the preamble of claim 1.

Known swing pitched roof windows each have two oscillating bearings, which connect the casement on the sides in the region of its center rotatably connected to the frame. An escapement ensures that an independent swinging of the opened wing is prevented. For this purpose, the axis of rotation is braked or a braking element is recorded braking near the axis of rotation in a circular arc guide.

The document EP-A-874 102 discloses a swing window having all the features of the preamble of claim 1.

The invention has for its object to provide a novel swing window, the other Construction and in particular is inexpensive and stable.

This object is achieved in a swing window of eingagnsgennanten type by the characterizing features of claim 1. Due to the each vertical spar of the sash associated guide rods which is pivotally mounted in the region of its upper end on the frame and wear in the region of its lower end by means of a swing bearing the casement, a construction comparable to a hinged swing-window is provided, but not according to the invention is used for a folding function in the conventional sense, but serves as a swing bearing for the swing window. It is therefore a "pure" swing window, which has only this opening function. Due to the configuration according to the invention, that interact independently of all possible positions of the actuating handle or actuator, the brake element and the counter-element with closed and open in the ventilation range wing frame together, is a displacement of the sash in a folding open position impossible or due to gravity, which does not push the sash on the frame. In particular, the actuating handle can thus not be brought into a position in which the drive rod system or braking element and counter element are decoupled and it would be possible to unfold the wing. Rather, the swing opening function is fixed by the coupling of brake element and counter element. The same applies to a concern of the braking element on a counter element (contact track) on the frame. This system of brake element and counter element is always maintained in the ventilation position range, in particular due to the weight of the sash, so that there is no folding opening position. It has been found that the construction according to the invention can be realized simply and stably and permits safe operation of the swing window, even in the open position. "Ventilation range" is the adjustment range of the open sash, which corresponds to the "normal" swing opening of the casement, without the movement is carried out so far that the cleaning position of the sash is achieved. In the course of this application, a further shifted swing window is referred to as being in cleaning position.

According to a development of the invention, it is provided that the braking element or the counter element moves within the ventilation setting area along a linear or substantially linear path. Thus, the relocation occurs the element on a straight line or on an approximate straight line, wherein preferably the counter-element is a positive guide in which the braking element is guided. If the counter element is guided along a linear guide, that is to say a straight guide is provided, a displacement movement of the braking element along a straight linear path is automatically ensured.

According to a development of the invention, it is provided that the linear path runs parallel to the opening plane of the window frame or to the glass pane plane of the sash frame. Additionally preferably, the linear path is parallel to the longitudinal extent of the vertical struts of the sash.

According to a development of the invention it is provided that, at least when the casement is closed, the swing axle is closer to the lower cross member of the casement than the brake member. Moreover, it is preferably provided that with respect to the opening plane of the window frame, the vertical distance from this to the swing axis is greater than the vertical distance to the brake element or counter element. This construction ensures that a slight opening of the guide rods relative to the frame adjusts from the closed position during the opening movement, that is to say when the sash frame is moved about the oscillating axis, with the result that the oscillating axis slightly displaces upwards and thereby a linear movement As already described above, the braking device becomes possible.

According to the invention it is provided that connects to the braking device a catching device for fixing a cleaning position of the casement. If the oscillating window is pivoted along its maximum ventilation setting range, it then passes into the cleaning position, that is, from the living room, the outside of the window pane is accessible and can therefore be easily cleaned. The braking element is held in the cleaning position by a corresponding catch stop of the catching device, so that the cleaning position can not be left independently.

For a simple assembly, so a trouble hanging the sash, between the braking device and the catcher a disengagement of brake element and counter element enabling mounting gap is provided. This mounting gap allows to insert the brake element in the counter element when hanging the sash in the frame. The same applies when disassembling, that is, the two elements can be brought disengaged.

Preferably, braking device and catching device are designed as separate components, wherein as a braking device in particular metal material and as a catching device in particular Plastic material is used for the production of these parts.

Finally, the braking element is a sliding or rolling element and the counter element is designed as a sliding or rolling guide. The sliding or rolling element is preferably located on the casement; the sliding or rolling guide is arranged on the frame.

According to FIG. 1 The pitched roof window 2 designed as a swing window 1 has a frame 3 and a casement 4. The casement 4 is provided with an actuating handle 5, with which the locking position of the casement 4 relative to the frame 3 can be brought about a corresponding espagnolette. Furthermore, an unlocking position can be approached with the actuating handle 5, out of which the oscillating window 1 can be swing-opened ( FIG. 2 ). In its installation position in the upper region 6, the frame 3 has a pivot axis 7, about which the two guide rods 8 can be pivoted. A comparison of FIGS. 1 and 2 shows that the guide rods 8 move when swinging open the window by a small angle in the direction of arrow 9 about the pivot axis 7. In the one, upper end portion 10 of the guide rods 8, the pivot axis 7 is arranged. In the other, lower end portion 11 of the guide rods 8 is a swing axle 12, by means of which the casement 4 can swing horizontally approximately in its central region. For the sake of representation (page presentation) are the FIGS. 3 to 6 only one guide rod 8 removed. The arrangement is such that each vertical beam 13 of the frame 2 or each upper portion 14 of each vertical beam 15 of the sash 4 is associated with a guide rod 8. Approximately in the middle region of each vertical beam 13 of the frame 3, a braking device 16 is arranged, to which a brake member 17 is part, which is arranged on the casement 4. Furthermore, the braking device 16 has a counter element 18, which on the frame 3 is stationarily positioned. On the lower horizontal member 19 of the frame 2 facing side is located next to the braking device 16, a catching device 20, wherein between the braking device 16 and catching device 20, a mounting gap 21 remains free.

If the sash 2 from the open position of FIG. 2 further displaced in the counterclockwise direction about the swing axis 12, the cleaning position is in accordance with FIG. 3 ingested.

The following will be on the FIGS. 4 to 6 discussed in greater detail, which illustrate the area around the swing axle 12. From each of the guide rods 8 is a flat plate web 22, which has an obtuse-angled sheet 23 and extends in the direction of the frame 3 and then expires by means of an approximately 100 ° arc 24 in a free end 25. In the region of the free end 25 of each flat plate web 22 is a bearing bore 26, in which a bearing pin 27 engages, which also passes through a bearing bore 28 of a bearing plate 29. The respective bearing plate 29 is attached to the casement 4.

Furthermore, starting from each end face 30 of the sash frame 4 approximately in the central region of its longitudinal extension, the brake element 17 in the form of a rotatably mounted on a bolt 31, rectangular or square shaped piece 32, according to the FIGS. 4 and 5 engages in the counter-element 18, which is designed as in the direction of the casement 4 open guide channel 33. The cross-sectional dimensions of the molding 32 are selected such that in the guide channel 33 an inhibition with respect to a shift occurs such that the fitting 32 can be moved only by applying a certain force in the guide channel 33, wherein the size of the force is chosen so that a set swing window opening position not automatically - not even in light wind pressure will leave.

The guide channel 33 is designed to be open in the direction of the catching device 20, so that there the molded piece 32 can emerge with corresponding swinging position of the swinging window 1 and can enter the mounting gap 21, which is open at the top (arrow 34) and therefore during assembly or disassembly the sash 4 allows insertion or removal of the molding 32.

If the swing window 1 so far swung around the swing axle 12 forming bearing pin 27 that the fitting 32 enters into a catch stop 35, so a further swing is prevented and taken the cleaning position.

From the FIGS. 1 to 6 is clearly seen that in the course of swing opening of the swing window 1, the guide rods 8 pivots about its pivot axis 7 in accordance with the adjusting conditions with respect to swing axis 12 for guiding the mold 32 in the guide channel 33. If the fitting 32 is in the assembly 21, it is basically a further swinging up the guide rods 3 possible, but practically not given due to the weight of the sash 4. Rather, on further Verschwingen the fitting 32 into the catch stop 35, which has an overedge edge 36, so that in the cleaning position further lifting of the guide rods 8 and thus the sash 4 is prevented. In particular the FIG. 5 It can be seen that approximately in the region of the end 37 of the guide channel 33, the plane within the braking device 16, rectilinear track increases (slope 38), so that by means of the shaped piece 32 when swinging the sash 4 lifting occurs.

From the FIGS. 4 to 6 It can be clearly seen that in the installation position the swing axle 12 is located above the brake element 17, wherein the arrangement is made such that the swing axle 12 is closer to the lower horizontal spar 19 and the corresponding lower horizontal spar 39 of the casement 4, as the brake element 17, So the fitting 32nd

The braking device 16, so the brake element 17 and also the counter element 18 are made of metal. As a separate assembly to the catcher 20 is executed, which consists of durable plastic.

Since - regardless of the position of the actuating handle 5- during the ventilation range, ie during the swing angle range in which the fitting 32 is located within the guide channel 33, only a sash displacement to the Oscillating axis 12 is possible, it is in the subject of the invention to a pure swing window that does not allow folding function in the sense of a known hinged swing window. Nevertheless, there is a slight pivoting movement about the pivot axis 7, that is, the guide rods 8 are slightly displaced in the direction of the arrow 9 or against the direction of the arrow 9 in dependence on the sash position. The kinematics given hereby is advantageous for cover plates on the lower sections of the vertical struts 15 of the sash frame 2, which are approximately covered in the region of the swing axle 9 by corresponding cover plates on the guide rods 8. An abutment against the lower end edges of the on the guide rods 8 located cover plates is avoided. Furthermore, the kinematics resulting from the construction permit the use of a brake device 16 arranged approximately in the horizontal central region of the casement 4 or the frame 3, in particular paired with the proviso that a linear braking, ie along a straight line, takes place.
