The invention relates to a ventilation device for sliding windows that can be opened from below Railway car, consisting of a ventilation duct, the walls of which are located in the interior of the vehicle from a disc held in a frame, inclined upwards with adjoining, on its sides, approximately triangular bracket plates are formed, with the movable disc of the Sliding window can close the ventilation duct on the outside.

The invention is based on the object of providing a ventilation device of the type described above create, the draft-free and simple and cheap in terms of their structure and adaptable to given conditions is such that it can be installed in existing cars and when installed in new ones Car does not require any change to the previous window construction.

In order to achieve this object, the console plates are according to the invention in the device mentioned at the outset with the adjacent leg of the associated, as known U-shaped, non-adjustable Frame connected via flange strips and set with these and the inserted into it Disk is a known attachment housing that with its bracket plates on the frame of the Sliding window can be clamped via screws, while in a known manner one in an open longitudinal groove the base strip of the attachment housing arranged flexible sealing strips to the ventilation duct movable disc seals out.

Although it is already a ventilation device for opening lowerable windows of railroad cars known that from a ge * held in a frame rotatable and inclined to be arranged Washer, the lower frame part rests against the upper edge of the same when the window is open. However, this device has a number of significant disadvantages. In particular, she is not draft-free. Due to its adjustability, the disc can be unavoidable due to the fact that the train is moving occurring vibrations also easily change their position. In addition, the device is in its attachment somewhat complicated and therefore expensive. After all, it can lead to some rattling Make noises when the train is in motion.

Furthermore, a tilt window for vehicles is known, which is mounted in a window shoe Disk is connected to the upper part of the window frame by means of a toggle spring hinge, wherein approximately triangular console plates are attached to the sides, which in the open position of the

Disc together with this form a ventilation channel. This device is proportionate in structure laborious. In addition, it assumes the presence of a special window construction ahead, as it can only be installed above a window. For the common ones with railroad cars Window construction, this device is not applicable. It can therefore not be retrofitted will.

A third known ventilation device on motor vehicles consists of a thin plastic film, which is attached to the frame above the lowerable window towards the inside and which extends downwards and to one side. However, this device is not suitable for that of the invention to solve underlying problem because it is largely exposed to damage and the vehicle occupants are likely to feel the downward flow of air disturbing.

Finally, there is a ventilation device in the upper area of a lowerable sliding window known from vehicles that consist of a diagonally upward and inward facing, a seal opposite the sliding window having wall part and two approximately triangular bracket plates on the Ends of the same, the channel formed by this still requires an air duct on the outside of the window. This device is relatively complicated in structure and requires adaptation to different window ratios of larger production work. Another disadvantage is that the

sloping wall part is opaque, which means the field of vision and the passage of the Light available area can be reduced.

The device according to the invention avoids the disadvantages of these known constructions. she is simple and cheap in its structure and without any special effort on given window constructions customizable.

An exemplary embodiment of the invention is shown in the drawing. It shows F i g. 1 the interior and

F i g. FIG. 2 shows the external view of one provided with the ventilation device according to the invention, according to FIG sliding window that can be opened at the bottom,

F i g. 3 shows a section along the line III-III of F i g. 1 and

F i g. 4 shows a section along the line IV-IV of

The sliding window contains a lower, fixed pane 1 and an upper, by means of an ao Hand crank 3 up and down movable disc 2. The hand crank 3 is attached to a cross member 4. It but of course an embodiment is also conceivable in which the upper disk in another Way is movable, e.g. B. directly by hand. Instead of the two disks 1 and 2, only a movable disc may be provided.

Part of the ventilation duct is formed by a disc 5 mounted inside the car, which starting approximately from the plane of the movable disk 2, runs obliquely upwards, so that the ventilation flow is directed against the ceiling of the vehicle. This disc 5 consists of a transparent one or translucent material. It is arranged in a U-shaped frame, its base bar 6 runs parallel to the upper edge 7 of the sliding window opening.

The two legs of the frame can be detached laterally at 9 on the adjacent one via flange strips approximately triangular bracket plate 10 attached, which in turn on the sliding window frame via screws is clamped. These console plates 10 form the side wall parts of the ventilation duct, which is shown in FIG Connection with the disc 5 and its frame represents a known attachment housing.

On the base strip 6 of the U-shaped frame, an open longitudinal groove is provided in which a sealing strip 11 is arranged, which the ventilation duct to the movable pane 2 of the sliding window seals out.

Furthermore, stop or adjustment devices can be provided to adjust the Washer 2 to facilitate. It can be locking balls, identification marks or the like. Through this becomes the possibility of opening the pane 2 completely, i.e. up to about the height of the cross member 4 let down, not hindered.

Fig. 3 shows that the ventilation device also allows the attachment of curtains 12, which slide on a guide 13 which is attached to a bracket 14. The latter is about at the level of the upper edge 15 of the pane 5. With such an arrangement, the curtains 12 remain while the vehicle is in motion outside of the air flow entering through the ventilation duct. So you don't flutter.

For draft-free ventilation of the car, it is only necessary to move the movable pane 2 down a little to move. The parts forming the ventilation channel do not require any handling. the Air then flows between the upper edge 8 of the pane 2 and the upper edge? the sliding window opening into the ventilation duct.

Claims (1)

Claim: Ventilation device for sliding windows of railway wagons that open downwards, consisting of from a ventilation duct, the walls of which are located inside the vehicle from one in one Frame held, obliquely upwards arranged pane with on its side adjoining, approximately triangular bracket plates are formed, with the movable pane of the sliding window can close the ventilation duct on the outside, characterized in that the bracket plates (10) with the adjacent Legs of the associated, as known U-shaped, non-adjustable frame Flange strips are connected and with this and the disc (5) pushed into it represent known attachment housing that with its bracket plates on the frame of the sliding window Can be clamped via screws, while in a known manner one in an open longitudinal groove the base strip (6) of the attachment housing arranged, flexible sealing strip (11) the ventilation duct to the movable disc (2) seals.
