DESCRIPTION:
BRIEF SUMMARY
The present invention relates no a ventilation device.
It is the maim object of the present invention to provide a versatile ventilation device for fitting on windows and the like.
According to the present invention a ventilation device for use at windows and the like, comprises a main duct body adapted for throughflow of ventilating air, said body comprising a plurality of parts certain of which are adapted to permit variation in the width of the device.
Preferably =he parts interfit so that when the ventilation device is assembled the device has structural integrity.
Preferably means are provided for connecting said parts to enable said width variation of the device, and preferably said width variation means Comprises a male-female interconnection.
In a preferred embodiment the ventilation device comprises inlet and outlet portions, and the plane means connecting said portions, width variation of the device being achieved via said plate means. The inlet and outlet portions may be similar, essentially representing minor images of each other, and the device can be symmetrical above a mid-plane.
Preferably at least one of the inlet and outlet portions includes an outer weather member, means being provided to releasably connect said member into said one portion.
Preferably the ends of the main duct body are closed by closure assemblies which are adapted for compatibility with main duct bodies of varying width .
Embodiments of the present invention will now be described by way of example with reference to the accompanying drawings wherein:
FIG. 1 shows a cross-sectional elevation of a ventilation device according to one embodiment of the present invention;
FIG. 2 shows a pictorial "exploded" view of the ventilation device, while FIG. 3 shows a plan view and FIG. 4 an end view; and FIG. 5 shows a cross-sectional elevation of a ventilation device according to a second embodiment of the invention. FIG. 6 shows a part cross-sectional elevation of a ventilation device Similar to that of FIG. 1 but with modifications, FIGS. 7, 8 and 9 show side views of the ventilation device of FIG. 6 as applied in various window applications; FIG. 8 showing parts of the end cap; FIGS. 7A and 9A show end views of detail trims used in the FIGS. 7, 8 and 9 applications; FIG. 10 shows a pictorial view of a nose cap as used in the ventilation device of FIG. 6 while FIG. 11 shows the section 11--11 of FIG. 10; FIG. 12 shows a pictorial view of a closure plug used in the FIG. 6 device while FIG. 13 shows a view in the direction of the arrow labeled FIG. 13 in FIG. 12; and FIGS. 14A-14E show several further modifications.
Referring to FIGS. 1 to 4, a ventilation device 1 for fitting as a separate and individual item at the outer edge of a window frame F comprises a main duct body 1A including a first, inlet, body portion 2; a second, outlet, body portion 3; and plane members 4 joining the body portions 3, and the arrangement of the vent device 1 is such as to permit the device 1 to cater conveniently for different widths W of the frames F.
As can be seen in FIG. 1, the body portions 2, 3 are exactly similar, the device 1 in fact being symmetrical about a mis-vertical plane M--M, and this provides substantial economies in the manufacture of the device 1, especially as fewer extrusion tools are required. Additionally, the ventilation device 1 is simple to assemble and this provides further economies.
Each body portion 2, 3 comprises a main support part and a weather part 6 connected to the part 5 by male-female connections 7, 8, the support parts 5 being adapted to rest on the frame F while the connection 8 can be of snap fit type to permit easy release of the part 6. The weather part 6 includes a lateral wall 9, carrying the male element of the connection 8, and apertured to permit airflow and the body part 5 also includes an apertured wall 10 thereby providing a conduit 11 for exterior to interior (or vice versa) airflow across the top of the frame F. Additionally, the part 5 includes a downwardly extending wall 12 providing a seal forma
