Description

The present invention relates to a window or a door with a glare and wing frame according to the preamble of claim 1.

Such windows or doors have already become known in various designs. From the DE 201 05 296 U1 is a ventilation device for a window or a door has become known, which is arranged in an arranged between the window frame and sash folding chamber, which is connectable for ventilation via openings with an interior and an environment to allow a limited exchange of air between the interior and the environment. For this purpose, a box of the ventilation device is attached to the frame, which compresses the stopper seal on the casement so far that an opening gap is formed, or that the stop seal is recessed in the area of the box. In order to close the air exchange between the interior and the environment, a slider is arranged on the room-side end face of the sash.

From the EP 1715134 A2 a window or door ventilation system has become known, comprising a trained in the window or door rebate vent whose inputs and outputs are formed by interruptions or perforations in the circumferentially formed between a window or door leaf and a window frame or door seal, wherein in the ventilation path, preferably in the window or Türfalz arranged first window or door ventilation element with a Belüftungsvolumenstrombegrenzer in the form of a luftdruck- and / or ventilating Volumenstromabhängig automatically opening and closing shuttle valve and a second window or door ventilation element in the form of a sealing slide in an interruptions and perforations of the circumferential window or door seal occlusive closure position is movable, are arranged.

After DE 199 29 133 C2 a plastic window has become known in which at least one folding fan is provided in the rebate, which has an air guide chamber and a flow restrictor, and that the folding fan on the frame is attached. In the region of the folding fan, a fan seal is provided on the opposite side of the casement, which is designed as a fake seal and is correspondingly narrower than the wing seal adjacent to the respective ends of the folding fan on the wing frame side of the fake seal.

A disadvantage of the above-described plastic window that abuts with a relative displacement of the sash to the frame of the folding fan to the sash seal and not the fake seal, which can lead to an impairment when closing the window or the door. Furthermore, the folding fan is arranged in the rebate space. With the arrangement of the functional fitting components for closing or tilting the window or the door, which claim the area of the rebate area alone, the position of the rebate ventilator in the window or the door is already restricted. The embodiment of the ventilation device according to the DE 201 05 296 U1 and the EP 1715134 A2 have for closing the air flow on the room side end face of the sash adjustable slide. The disadvantage here is that it can come during storage, transport or cleaning windows or doors by on the room-side end face of the sash protruding components to possible damage or injury. Furthermore, the slider is the wing flap to adjust massively. Accordingly, the ventilation device is disadvantageous way to adapt for different sash, which also makes up several versions.

From the DE 20 2005 002 132 U1 is to take a ventilation device, with a sash and a frame and at least one ventilation duct between an outside and an inside of the frame assembly. With an air flow limiting device, which has a limiting element, wherein the limiting element releases the ventilation channel in an open position and partially closes the ventilation channel in a closed position.
The ventilation device is attached to the wing frame, wherein the channel element can engage in a portion of the fitting receiving groove of the sash for the inner stop seal.

A disadvantage of these known embodiments, in particular in the DE 20 2005 002 132 U1 with the arrangement of the ventilation device on the casement, that by using the height of the entire rabbet area it can come when closing or when opening the window or the door to grinding noise, for example at Dimensional inaccuracies of the sash to the frame. But even in this embodiment, the air exchange between the interior and the environment is adjustable by a valve disposed on the room-side end face.

The invention is therefore an object of the invention to provide a window or door with a simple design and functionally reliable ventilation device that can be particularly easy to assemble and eliminates all the disadvantages described above.

The solution of this problem is achieved by the means of the characterizing part of claim 1.

The arrangement causes the ventilation device in the closed state of the window or the door with an actuator to regulate an air flow or possibly to open or close. In addition, the ventilation device is simple and can be produced only by a few components and easy to install. It is particularly advantageous that the ventilation device is divided into two sections. The first section consists of a housing part, which connects the ventilation device with the frame or sash. The second portion is an actuator which is rotatably supported in the housing part, wherein the rotation axis is directed in the longitudinal direction of the air duct. Even with an adjustment of the ventilation device for regulating the air flow, the size and the outer configuration of the ventilation device do not change. By the wing flap and frame independent arrangement of the ventilation device, the ventilation device can be both in the closed position and with opening the sash in rotational position even in the installed state subsequently easily Assemble and disassemble. By interrupting the seal and attaching the ventilation device on the sash, the closing of the window or the door is reliable, since the seal with the arrangement of the ventilation device does not interfere.

It has also proved to be advantageous that the actuator has a circular arc shape in cross-section and the housing part is adapted to its the supporting ends of the circular arc shape of the actuator. With the rounded shape, the ventilation device receives an optically advantageous embodiment, which is the visible components, for example, the bands or hinges of the window or door adapts. Furthermore, the circular arc shape of the rotating or tilting axis of the sash fits that is, that the axis of rotation of the circular arc shape with the rotational or tilting axis of the window or the door is congruent, so that the ventilation device without further processing on the sash or frame can be mounted on the rotary or Kippachsenseiten.

In order to prevent escape of the air flow, a seal is arranged on the recess on the side facing the transition from the housing part to the actuator side in the longitudinal direction to the axis of rotation and thus to the air duct. The seal encloses a possible free surface or the clearance between the housing part and the actuator.

It is also advantageous that the actuator of the ventilation device between the axis of rotation and the room-side end face has a ventilation channel which is displaceable with rotation about the axis of rotation from a first overlapping position to a second released position and the air passage of the air flow in the second position through the air passage openings allows. The ventilation device thus obtains the largest possible opening for the air flow, which can freely flow into the interior of the room in the open position. The adjustment of the air flow is easy to operate, since the actuator is preferably on the free surface to the room side on the actuator itself to operate. Even with adjustment of the actuator by rotating about the axis of rotation, the ventilation device remains advantageously unchanged in all possible switch positions measured from the room-side end face of the frame to the more visible free end both visually and the size unchanged. Thus, the height of the wing flap is not overlapped even when adjusting the ventilation device.

According to a further advantage, the housing part at the bearing ends and at the free ends of the actuator on a rotation limitation.
With adjustment of the actuator about the axis of rotation, the ventilation duct arranged in the actuator is displaced from a first overlapping position to a second released position, wherein the air passage of the air flow in the second position is made possible by the air passage openings. The rotation limitation causes an optimal ventilation and ventilation lock position in the end positions. A malfunction is excluded.

According to a further advantageous feature of the invention, forms the

Ventilation device, comprising at least one housing part and the actuator, a component. With this configuration, the ventilation device can be easily installed.

The structure of the ventilation device extends from the room-side end face of the frame, the wing flap encompassing the wing flap circumferential surface and is dimensioned smaller than the height of the wing flap. The design of the ventilation device thus has optical advantages, whereby at the same time possible damage during storage or during transport of windows or doors are excluded.

It has also proven to be advantageous that the housing part has holes for the passage of a fastening screw for frictional connection to the sash. Thus, the installation of the ventilation device on the casement or the frame of the window or door can be relatively easily made.

A further advantageous embodiment provides that forms an enclosed space or recess with an air passage opening for the air flow with investment of the housing part to the frame, which comes with its free end to the air duct in the rebate. The free end of the housing part is not wider than the distance in the region of the seal between sash and frame. The cross section of the air duct remains unchanged in the area of the ventilation device. Thus, the air flow can flow unhindered into the ventilation device and the ventilation device can be mounted even without consideration of the arranged in the rebate for closing or tilting the window or the door function fitting components. The arranged on the wing flap structure of the ventilation device is dimensioned so that with specification of the dimensions of a maximum airflow can be achieved.

In order to realize a cost-effective production as well as a simple and quick installation of the ventilation device, the actuator is preferably formed in two parts and semicircular and connectable by form-locking elements. The production is simplified in that the housing part and the actuator is preferably made of a thin-walled plastic material.

It is also particularly advantageous that the ventilation device without further assembly or editing of the sash or window frame to another For example, arranged on the air duct in the rebate ventilation devices can be coupled.

In Fig.1 is a window or a door with a frame 1 and a sash 2 shown, wherein the frame 1 covered by the sash 2 with a wing flap 12. Between frame 1 and sash 2 more air passage openings 4 are provided for forced ventilation, wherein the air flow 13 is shown schematically with arrows. The sash 2 is fully or partially open by means not shown function fitting components via an operating handle 3.

In Fig. 2 the window frame 1, the sash 2 and a ventilation device 10 is shown in a perspective. The sash frame 2 frames a glass sheet 6 which is interposed between a seal, not shown, and a seal received on a glazing bead.

Between the frame 1 and casement 2 an air duct 5 is formed in the fold, wherein on the outwardly directed side a seal 7 and on the inwardly directed side of the ventilation device 10 to Fig.2 recognizable seal 9 is provided.

Depending on how the window or door is designed, ie whether the window or the door can be opened outwards or inwards, the terms "lying outside" or "lying inside" can also be exchanged accordingly.

In the seal 7 and the seal 9 each not shown recesses are provided so that an air flow 13 can take place from the outer to the inner side. The fold forms the here indicated air duct 5, through which the air flow 13 in this embodiment, finally passed to the upper horizontally extending window or door legs and can be performed by the ventilation device 10 in the interior of the room.

To Fig.2 to Fig.12 the ventilation device 10 consists of a housing part 20 and an actuator 14, between the frame 1 and the wing flap 12 after Fig.2 and Fig.5 to 8 arranged and attached.
To ensure proper closing of the window or the door, it is particularly important that the free end 23 of the housing part 20 is not wider than the distance 22 between sash 2 and frame 1 in the region of the seal 9, not shown. With investment of the housing part 20 to the frame 1, an enclosed space or recess 21 forms with an air passage opening 4 for the air flow 13. The recess 21 forms with Appendix to the frame 1 in the area of the wing flap an enclosed space with an air passage opening 4 for the air flow thirteenth The recess 21 can be so dimensionally matched to the amount of air flow 13. In order to achieve the largest possible exchange of air with a small gap between the frame 1 and wing flap 12, a wall facing the room-side end face 17 is preferably eliminated. Thus, the recess 21 can be easily cleaned in a possible disassembly of the ventilation device 10. Furthermore, the housing part 20 after Fig.5 and Fig.6 designed so that the free end 23 extends to the air duct 5 in the rebate, and thus reaches a connection to the air duct 5, which is already used due to the arranged there functional fitting components of the window or door and for the air flow.

The air passage openings 4 consisting of the recesses 21 and the ventilation duct 15 can be designed so that they can vary depending on the design of the ventilation device 10 in number.

It is also after Fig.2 to Fig.4 the actuator 14 in cross-section circular arc-shaped. The housing part 20 is also adapted to its supporting ends 16 of the actuator 14 with formation of a circular arc shape. In addition, on the one hand the shape of the functional components, for example, the hinges or bands of the window or the door visually adapted, on the other hand, the air flow 13 can be easily regulated by the ventilation device 10.

Since the axis of rotation 8 forms the axis of the circular arc shape of the actuator 14 and the housing part 20 and at the same time congruent with the rotational or tilt axis of the window or the door is designed, the position of the ventilation device 10 on the window or door can be freely selected.

To FIG. 9 to FIG. 12 For example, the ventilation device 10 has a rotation limitation 11 on the bearing ends 16 of the housing part 20 and on the free ends 19 of the actuator 14. Upon manual actuation of the ventilation device 10 via the actuator 14, the ventilation device 10 is replaced by the rotation limit 11 an optimal position in the end stops in the overlapping position, ie until a complete closure of Air flow 13 takes place, or in the released position for the largest possible air flow 13. Within the adjustment of the air flow 13, depending on the position of the actuator 14 and thus the position of the ventilation duct 15 can be regulated.

For ease of assembly and as an optical advantage, form after Fig.3 and Fig.4 the housing part 20 and the actuator 14 is a component.

To Fig.9 and Fig. 10 has the ventilation device 10 according to the invention on the housing part 20 to the end face 17 of the frame 1 corresponding holes 25 for the passage of a fastening screw 26 which connects the ventilation device 10 to the frame 1 frictionally on the end face 17. The seal 9 is interrupted in the region of the arrangement of the ventilation device 10 in an advantageous manner.
