Description

The present invention relates to a window, in particular skylight, with a casement, which is pivotable against a frame, with at least one positioning aid, comprising a Aufstellarm, articulated with a first end to the wing frame and a second end via a sliding shoe in a sliding cassette along the Blendrahmens is displaced, or vice versa, wherein at least one brake element (18) with the sliding cartridge (16) is in operative connection and is connected to the sliding block (14) via at least one connecting element (22).

Under window here any kind of openable wall or roof element is understood, which has the above-mentioned elements of sash and frame, which are pivotable to each other. In particular, including window structures are understood that are known as Drehkipp- or pantry window. In this case, the present invention is not applicable to translucent window elements but also to opaque or semi-translucent elements.

Above-mentioned windows and in particular roof windows are known from the prior art and find their use in wall elements and roofs with different roof pitch. Between sash and frame usually an erection is provided to facilitate the pivoting of the sash against the frame. These erection aids are usually reinforced spring force or equipped with a similar force elements, such as a hydraulic or an electric motor with associated spindle drive. They usually consist of a sliding block, which can be displaced in a sliding guide, which is arranged either on or on the sash frame or window frame, and a Aufstellarm of this movable Sliding shoe and the opposite component, that is, either the frame or the sash, depending on where the slide is arranged runs. The sliding guide is usually arranged as a sliding cassette, which surrounds the sliding shoe more or less completely and this granted a linear guide. The shoe itself is preferably designed as a sliding pin, which is formed in its outer shape complementary to an inner shape of the sliding cassette, so as to grant a linear guide to an additional extent and to ensure reliable operation.

The attachment points of the first and second ends of the Aufstellarms are chosen so that a pivoting of the sash against the frame occurs by a displacement of the shoe in the sliding guide or Gleitkassette. In order to support this pivoting movement, a tension spring, for example, is attached to the sliding shoe, which supports the opening of the casement by an active displacement of the sliding shoe within the sliding cartridge. It can be used with the same effect but also a torsion spring or a similar force element, which is arranged between Aufstellarm and sash or frame. The erection aid is generally adapted to the rest of the roof window construction, that the roof window is usually held at least in a full open position. Roof window constructions are also known from the prior art, in which the casement can be held in different open positions to the frame, or even only a simplified opening or closing is guaranteed.

Furthermore, erection aids are known from the prior art, which serve more the definition of the sash with respect to the frame and so different locking elements, etc., to set the sash, for example, in a fully open, in a half-open or any other conceivable and desired opening position ,

However, all known windows or skylights equipped with the above installation aid have the disadvantage that adaptation to the forces acting on the erection aid, in particular due to the weight of the casement, is usually only possible in a complicated manner. This means that for different casement usually different erection aids must be made in order to provide suitable opening or closing support forces or locking forces with respect to the loads acting. For example, if the erection aid provided with a spring element, which is the opening of the sash with respect to the frame should facilitate the Aufstellarm, so depending on the size of the window different spring elements or different attachment points for the Aufstellarm to choose to ensure the required opening and closing forces that must apply the user of the window can.

Another disadvantage, however, is that in particular when retrofitting existing windows with sunscreen, cleaning or energy supply elements an adaptation of the erection of these additional installations and the resulting weight change is usually very complicated and costly possible. Here remains according to the prior art usually only the replacement of the entire installation aid or certain modules as a way out.

In addition, from the prior art, the problem is known that the locking or positioning of the sash in certain opening positions requires a very complicated and usually costly construction of the erector or certain braking devices. In this context, in particular the targeted adjustment of the erection aid to the desired opening or closing force of the casement is a complex problem, which can usually only be achieved with expensive means.

A corresponding roof window with Aufstellhilfe shows the EP 1 873 323 A1 which is state of the art under Article 54 (3) EPC. It discloses a pop-up window, in which an upright is positioned in the form of an erection between the sash and the frame. The raising arm is hinged at one end to the casement and slidable with a second end via a sliding block in a sliding cassette along the frame. The shoe includes a braking member disposed inside the slip cassette and operatively connected to the inner walls of the slip cassette. About a lever system, the sash can be fixed by this brake element on the shoe in at least one opening position. Again, however, the complicated structure and the problem of a targeted adjustment of the erection of desired opening or closing forces of the sash have been found to be problematic.

The EP-A-1 052 342 describes a skylight with a shoe, which is provided with a movement means in the guide and having an independent of the movement means acting, adjustable brake.

The present invention is therefore the object of further developing a window and in particular a roof window of the type mentioned so that it is cheaper and easier to manufacture and adaptable to additional installations.

This object is achieved by a window, in particular roof windows according to protection claim 1.

In particular, this object is thus achieved by a window, in particular skylight, of the type mentioned in that at least one brake element is disposed on an outer wall of the sliding cassette and is in operative connection therewith.

Due to the arrangement of the brake element on the outer wall of the sliding cassette, so that the outer wall and the brake member are in operative connection with each other, a "swing brake" can be realized in a simple and cost-effective manner. By the connection of the shoe with the brake element via a Verbindungsclement the brake element slides congruent to the shoe on the outer wall of the sliding cassette along, wherein the braking force between the brake element and outer wall depends inter alia on the contact pressure, which the connecting element generated between the brake element and the outer wall of the sliding cassette. Of course, the resulting braking force will depend to a greater extent on the size of the braking element and the surface or material of the braking element and the outer wall of the sliding cassette.

The outer wall of the sliding cassette preferably has a braking surface, and in particular an exchangeable braking surface. In this way, a particularly effective braking effect between the brake element and the outer wall of the sliding cassette or the sliding block and the slide cassette can be realized. Here, in particular, the integral formation of a braking surface in the sliding cassette is possible, in which case appropriate friction coefficients can be achieved by targeted surface treatments. In addition, of course, the arrangement of explicit braking surface elements on the outer wall of the sliding cassette is possible. Here are all known from the prior art techniques, such as in particular the use of corresponding connecting means or adhesive for the arrangement of the braking surface on the outer wall conceivable.

It is also conceivable in this context to provide the outer wall of the sliding cassette with corresponding braking surfaces so that fixed predefined opening angles between the frame and the sash result. Thus, for example, if at the positions where the shoe is located when the sash is in a fully open position and in a half-opening position, corresponding braking surfaces are arranged, so this special opening angle "predefined", so that the user of the window when opening and Closing very easily drops these predefined opening angles.

Preferably, the brake element has a complementary to the outer wall of the sliding cartridge and in particular concave outer shape. In this way, the resulting braking force between the brake element and the outer wall or the aforementioned braking surface is optimized because a full-surface Reibauflage is guaranteed. The formation of a concave outer shape, which means that, for example, the slide cassette in the region of the contact point of the brake element has a circular cross section, also guarantees the linear displaceability of the brake element along the outer wall of the sliding cassette, without causing a tilting of the brake element. In addition, of course, the arrangement of corresponding grooves or guide elements is conceivable that guarantee the linear movement of the brake element on the outer wall of the sliding cassette.

Preferably, the connecting element is designed as an adjusting element such that a braking force between the braking element and the outer wall is adjustable. Here, for example, the formation of the connecting element as a screw is conceivable, which can be introduced into a corresponding screw receptacle or connector receiving the sliding shoe. By a specific choice of the torque when screwing the screw or the connecting element so the braking force between the brake element and the outer wall can be adjusted.

In general, it should be considered that is pressed by a direct connection between the brake element and shoe on the connecting element, both the brake element to the outer wall, and the shoe on an inner wall of the sliding cassette. In this respect, of course, a corresponding complementary surface formation of the shoe and the inner wall of the sliding cassette is preferred. However, it is also conceivable to connect the sliding shoe via an adapter element with the outer or inner wall of the sliding cassette, in which case the connecting element for fastening the braking element can then be arranged in or on this adapter element. This makes it possible inter alia to form the brake element linearly displaceable with the sliding block, without causing a change in the contact pressure between the brake element and the outer wall a change in position of the sliding block inside the Gleitkassette. This then preferably does not contribute to the braking effect, with such a separation between plain bearing and brake is basically a preferred embodiment.

Of course, all known from the prior art actuators may be used instead of the aforementioned screw as an actuator. Here, in particular the use of locking or similar clamping elements are conceivable.

In order to ensure beyond a constant application of force from the connecting element in the brake element is preferably arranged between the connecting element or actuator one or a plurality of disc springs or a similar spring force element. In this way, even with very frequent load changes, that is, a large number of opening and closing movements, ensures the tight fit of the brake element with a defined braking force with respect to the outer wall of the sliding cassette. In addition, in this way, the wear of the brake element or the outer wall or the attached braking surface is taken into account, since for example when reducing the Bremselementdicke by the plate spring or similar force element always the same contact force is applied via the connecting element on the brake element.

Preferably, the connecting element is slidable via a slot in the outer wall of the sliding cassette with the sliding block. For this purpose, a slot is arranged substantially parallel to the sliding direction of the sliding block in the sliding cassette, via which the braking element is connected to the sliding block via the connecting element.

Preferably, the connecting element has a quick-release device such that it is adjustable between a locking position in which the braking force between the brake element and the braking surface prevents pivoting of the sash frame, and a pivot position in which the braking force allows pivoting of the sash. In a corresponding embodiment, it is possible, for example, the user of the window, by simply moving the quick-release device from the pivot position to the locking position, the window simply lock in a desired opening position. The quick-action clamping device acts in such a way that the braking force between the brake element and outer wall of the sliding cassette or braking surface of the sliding cassette is increased by a shift from the pivot position to the locking position so that further pivoting is reliably prevented. Only after releasing the quick-release device, the braking force between the brake element and the outer wall of the sliding cassette is reduced so that a pivoting of the window is possible again. By a targeted adjustment of the prevailing tension in the locking position or pivot position, the window is so reliable locked or pivoted with the previously specified force.

It is fundamentally relevant that the adjustment of the braking force between the brake element and the outer wall is preferably continuously adjustable via the adjusting element, so as to be able to make a targeted adaptation to the male forces or impacting forces.

Preferably, as mentioned above, the erection aid has a force element, in particular a linear spring element, which is in operative connection with the sliding block, in order to support a sliding movement of the sliding block in the sliding cassette. This facilitates in particular the opening and closing of the casement.

Further embodiments of the invention will become apparent from the dependent claims.

In the following, the present invention will be described with reference to an embodiment which is explained in more detail with reference to the drawings.

In the following, the same reference numbers are used for the same and the same parts.

The FIGS. 1 and 2 show a particular embodiment of the present invention both in a pure side view ( FIG. 1 ) as well as in a side view with a partially cut-up aid 6 ( FIG. 2 ). Shown here is as an embodiment, a roof window 1, in which a sash 2 is pivotally mounted against a frame 4. Between sash 2 and frame 4, the installation aid 6 is arranged, the (see FIG. 2 ) via a force element 24, which is designed here as a linear spring, the opening of the sash 2 with respect to the frame 4 facilitates.

For this purpose, the erection aid 6 a Aufstellarm 8, which is articulated with a first free end 10 on the casement 2. This articulation can be done by means of all known from the prior art method, in particular rivet or screw. Here, inter alia, releasable Anlenkverbindungen are conceivable to completely separate, for example, the casement 2 of the erector 6.

A second end 12 of the Aufstellarmes 8 is connected in this embodiment with a shoe 14 and hinged thereto, which in turn is linearly guided in a slide cassette 16. The shoe 14 is also connected via the aforementioned force element 24 with a force element mounting point 25. As a result of this connection, when the casement 2 pivots in the direction of the frame 4, the sliding block 14 moves away from the force-element mounting point 25 and thus prestresses the force element 24 embodied here as a linear spring. In a subsequent opening, that is, a pivoting of the sash 2 away from the frame 4, this bias is reduced, thereby facilitating the opening movement.

But since just this bias and the standing opposite her weight of the sash 2 must be precisely matched to u.a. To give a not too strong or not too weak opening aid, the brake element 18 according to the invention is provided on an outer wall 20 of the sliding cassette 16. This is connected via a connecting element 22 with the sliding block 14, so that during a movement of the sliding block 14 within the sliding cassette 16, the braking element 18 moves on the outer side 20 of the sliding cassette 16. The contact pressure which the brake element 18 exerts on the outer wall 20 of the sliding cassette 16 can be adjusted via the connecting element 22 embodied here as an adjusting element, and thus the braking force can be varied. In this way, a targeted adaptation of the positioning aid 6 with respect to the weight of the sash 2, the installation aid 6, the selected force element 24, etc. possible.

In the FIGS. 3 to 6 are now detailed views and sections of individual components of the embodiment of the FIGS. 1 and 2 shown.

So shows FIG. 3 a side view of the sliding cassette 16 which on the frame 4 (see FIG. 1 ) is mounted. The sliding cassette 16 has an accessible from the outer side 20 slot 26, which, as in FIG. 5 shown, the insertion of the connecting element 22 and the setting of the brake element 18 on the outer wall 20 of the slide cassette 16 and the guided inside the slide cassette 16 shoe 14 allowed. Next is in FIG. 3 a Kraftelementmontagepunkt 25 shown in which the in FIG. 2 shown force element 24 hung and thus can be determined.

FIG. 4 shows the brake member 18, both in section and in a side view accordingly FIG. 3 , wherein a bore 28 is shown, the implementation of the connecting element 22 (see FIG. 5 ) serves. The bore 28 is in this case formed as a countersunk bore, to a substantially surface of the same recording of the connecting element 22 in the brake element 18 to ensure. In addition, the complementary to slide cassette 16 outer shape is shown here.

FIG. 5 Finally, shows a cross section through the sliding cassette 16 FIG. 3 with partially mounted brake element 18. The brake element 18 is arranged on the outer side 20 of the slide cassette 16 that the bore 28 is in the brake element 18 in accordance with the slot 26 of the slide cassette 16. In this way, the connecting element 22 can be connected to the sliding shoe 14 mounted inside the sliding cassette 16. In order to ensure a uniform contact force between the adjusting element 22, brake element 18 and outer side 20 of the slide cassette 16, an arrangement of mutually oriented disc springs 23 is used between the adjusting element 22 and the brake element 18 in this embodiment. But here are also all other known from the prior art elastic clamping and clamping devices conceivable.

FIG. 6 Finally, FIG. 1 shows a side view and a section of the sliding shoe 14, which in this embodiment is formed congruently with the inner wall 21 of the sliding cassette 16. The shoe 14 has an adapter 30 which is the recording of the force element 24 (see FIG. 2 ) serves. In addition, the sliding block 14 has a connecting element receptacle 32 in order to receive the connecting element 22. The connecting element receptacle 32 shown here is, for example, a threaded bore, into which the connecting element 22 designed as a screw or adjusting element can then be screwed.
