BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a closure panel assembly, such as a window, a door, a partition wall, and the like, comprising a planar member secured in a profiled frame which is mounted for movement with respect to a complementary profiled fixed frame, between a closed sealed position and an aeration open position.
A closure panel is known in the form of a swinging casement window, wherein a separation slit between the circular contour of the profiled frame of the casement window and the casing surrounding said casement window defines a Z-shaped in cross section aeration gap between the profiled frame of the casement window and the casing. In order to obtain now satisfactory aeration through the gap surrounding the casement window and at the same time marked attenuation of the noise passing through the Z-shaped gap, it is necessary to secure relatively precise adjustment of the position of the casement window in respect of the casing. Such adjustment requires fittings functioning with precision and careful attendance, the first requirement increasing the cost of production and careful attendance as a rule is not provided.
Also other already proposed solutions for attaining aeration which as much as possible also prevent the nuisance of the passage of noise, such as, for example, the insertion of noise damping vents, require from the overall point of view a relatively considerable expense and as a rule also require much space, so that in many cases such solutions cannot be recognized where space is scarce.
Apart from the question of noise damping, the problem of the passage of dust in gap aerations must be given consideration, and also in this respect a relative precise adjustment must be provided in a Z-shaped aeration gap in an effort to prevent the passage of dust through the aeration gap.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a closure panel assembly of the kind described at the outset, which secures satisfactory, preferably adjustable, gap aeration, and at the same time satisfactory noise inhibition and extensive inhibition of the passage of dust and possibly satisfactory damping against the passage of flames in the case of fire; these characteristics must be provided without the requirement of particularly narrow tolerances in machining and without the requirement of particularly precise adjustment in use.
For such purpose the invention provides a closure panel assembly, such as window, door, wall, comprising a planar member secured in a profiled frame which is mounted movable with respect to a profiled fixed frame, such as a casing, against which it sealingly bears, in a closed position, to an aeration position being produced by opening the profiled frame from the sealing position, wherein there is an aeration gap between the profiled frame and the profiled fixed frame during a change in direction, a flexibly-sealing and/or noise damping and/or fireproof material being disposed on the side area of the aeration gap, the aeration gap between both frames in cross section having a serpentine pass, wherein at least in the narrowest aeration position in the range between one section open toward both frames and orientated in the exposed direction and one section open to the other side of both frames and orientated in the exposed direction there is at least one section orientated in the direction opposite to that of the exposed direction. The construction of the invention, due to the special course of the aeration gap, permits certain variation in the position of the profiled frame with respect to the profiled fixed frame surrounding the profiled frame without substantially changing the characteristics of noise damping and dust inhibiting, and due to the provided course of the aeration gap which produces very satisfactory noise damping, there can also be provided a relatively large gap cross section, which permits liberal passage of air for the intended aeration. The provided course of the aeration gap considerably inhibits the passage of dust
