Description

SPECIFICATION Ventilation grid with rotatable closing element The present invention relates to a ventilation grid having a rotatable closing element, in other words to a ventilation grid whose ventilation opening can be optionally closed or opened by adjusting the angular position of the closing element.
Mainly two kinds of ventilation grids are known, viz. ventilation grids with a slidable closing element and/or closing grid and ventilation grids with a rotatable closing element.
The present invention more especially relates to the second type of ventilation grid as is known from the Belgian Patent Specification 886,349 according to which the rotatable closing element mainly consists of a drum provided with diametrically opposed longitudinal grooves, and the vertical or horizontal application of these grooves results in an occasional ventilation between both sides of the ventilation grid. A wire mesh guard which is usually provided for preventing insects, dust and the like from passing through the grid is built in in the drum.
Such ventilation grids with a rotatable drum, however, are rather complex and as result are expensive and are relatively bulky. As such ventilation grids provided with a rotatable drum are mainly provided for being built-in in the top of windows, it is of course desirable that the ventilation grid occupies an area as small as possible in order to keep the window surface area as large as possible and not to reduce the light incidence.
According to the present invention there is provided a ventilation grid provided with a rotatable closing element, comprising two longitudinal profiles between which a longitudinal ventilation opening is formed, a rotatable closing element for closing said ventilation opening consisting of a single segment of a cylinder, and a window or cover hood provided on one of the profiles.
Two embodiments of the invention will now be described, by way of examples, with refer ence to the accompanying drawings, in which: Figure 1 is a transverse section through a ventilation grid constituting the first preferred embodiment; and Figure 2 is a transverse section through a ventilation grid according to the second preferred embodiment.
The ventilation grid according to the present invention as shown in the figures consists of the combination of two longitudinal profiles 1 and 2, between which a ventilation opening 3 is left, a rotatable closing element 4 for clos ing said ventilation opening 3 and a window dip or cover hood 5. Further, sealing elements 6 as well as a wire gauze element 7 are provided.
The profiles 1 and 2 are located mainly in a common vertical plane and are situated at a predetermined distance from one another so as to form said ventilation opening 3. At their ends facing each other each of them is provided with said sealing elements 6 that can make contact with the rotatable closing element 4 in order to provide in the closed position of the ventilation grid sealing of said ventilation opening 3.
The sealing elements 6 preferably consist of brushes but they can also consist of a strip of rubber, plastics, felt or any other similar material.
The window-drip or cover hood 5, which is preferably integral with the uppermost profile 1, consists mainly of a horizontal side 8 and a vertical side 9 which extends downwardly from one end of the horizontal side 8.
At their ends, the profiles 1 and 2 are preferably closed and mutually fixed by means of flanges not shown in the figures, wherein said rotatable closing element 4, which preferably consists of a single part-cylindrical element, is supported at its ends, e.g., in recesses 10.
Driving the rotatable closing element 4 can take place in any known way, e.g. by means of conical gears and a driving rod connected therewith or by means of any other suitable element.
The wire gauze element 7 is fixed in recesses 11.
According to the embodiment of Fig. 2, said recesses 11 are provided at the rims of profiles 1 and 2 respectively.
Naturally, many variants of the present invention are possible without departing from the scope of the invention as claimed in the appended claims.
It is clear that the cover hood 5, e.g. may have the shape of a quarter of a cylinder or may be partly bevelled as is the case in the embodiment of Fig. 2. The sealing elements 6 too can be fixed in different ways to the ends of the profiles 1 and 2 facing one another.
Preferably this takes place by means of strips that can simply be slid in grooves 12 and 13 provided therefore.
This way a very compact structure is obtained and according to some variant it is even possible to place such a ventilation grid simultaneously with a pane of glass in a window. For that purpose the top side of said pane of glass enclosed by the legs of the bottom profile 2 of the ventilation grid which in this case has a U-form, whereas the top profile 1 connects with the upper part of the window-frame.
