Ventilation device for roof openings

The invention relates to a ventilation device for roof openings with a base frame and a hood hinged to it on one side via a pivot bearing, which has a hood infill on the top with a plate held on the hood. Such ventilation devices are used in particular as smoke and heat extractors. The base frame can be integrated directly into the building roof or a facade, but also into a sloping building element or arranged on a base. Each ventilation device has one or more hoods, which can also be designed as flaps. Each hood is equipped with a pivot drive that is operated when required. The plate of the hood infill is usually made of translucent material. Other designs are possible.

Ventilation devices of this type are known in various designs. In particular, there are various designs of the hood infill for fastening the panel. What all designs have in common is that the panel is held at the edge between seals that are arranged on the associated components of the hood. This is complex in terms of construction and assembly technology.

The object of the invention is to simplify the construction and assembly of a ventilation device of the type described above.

This task is solved by clamping the plate at the edge between the legs of a U-profile to form a seal. According to the invention, special seals can be dispensed with because it has been found that clamping the plate at the edge between the legs of a U-profile can also provide a sufficient sealing function. This not only simplifies the construction of the hood but also the assembly of the hood infill because there is no need to insert seals and the plate can simply be pushed between the clamping legs of the hood infill.

In a preferred embodiment of the invention, the lower leg of the U-profile forms a support for the panel, while the upper leg of the U-profile grips the panel in a spring-loaded manner. In particular, the upper leg of the U-profile can extend almost directly over the top of the panel and rest on the top of the panel with an angled lip. This enables a very flat design and also good drainage of water that has collected on the panel of the hood infill. Residual water that nevertheless passes through the clamping connection between the U-profile and the panel can be drained off if the lower leg of the U-profile merges into a water drainage channel.

In the following, an embodiment of the invention is explained, as shown in the drawing; in which:

Fig. 1 shows a schematic and perspective view of a ventilation device,

Fig. 2 shows a partial vertical section through the article according to Fig. 1.

The ventilation device shown is arranged in the area of a building opening 1, which is surrounded by a base frame 2. The base frame 2 has a water drainage channel 3 in the middle. On the outer sides of the base frame 2 opposite the water drainage channel 3, flap-shaped hoods 5 are hinged via pivot bearings 4, which can be opened or closed with lifting cylinders 7 acting on hood cross members 6.

The hood 5 has a hood frame 8 and a hood infill 9 into which a plate 10 is inserted. In the embodiment shown, the plate 10 consists of translucent, extruded plastic material. The upper part of the hood frame 8, which borders the hood infill 9, forms a U-profile with two U-legs 11, 12, between which the plate 10 is clamped in a sealing manner at the edges. The lower U-leg 11 forms a support for the plate 10, while the upper U-leg 12 is designed as a spring and extends almost directly over the top of the plate 10 and is supported by an angled lip 13 on the top of the plate 10. The lip 13 is generally sufficient to seal against water standing on the plate 10. Residual water that passes through this seal is collected by a water drainage channel 14 formed between the lower U-leg 11 and the hood frame 8.

When the ventilation device is closed, the hood 5

with a web 15 adjoining the hood frame 8, sealingly rests on a seal 17 placed on the upper edge 16 of the base frame 2.
