DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to skylights and, more particularly, to a skylight assembly that is adapted to suit a variety of roofs of different angular pitches.
BACKGROUND ART
Most conventional skylight assemblies are manufactured according to a fixed design to accommodate a particular roof pitch or a narrow range of roof pitches. Such skylight assemblies cannot be easily used or modified to accommodate a wide range of roof pitches, say at angles of from 0 degrees to 45 degrees.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a skylight assembly that is constructed in such a way that it will suit a wider range of roof pitches than conventional skylight assemblies.
According to the invention there is provided an adjustable skylight assembly adapted to suit a variety of roof pitches, said assembly comprising a sunlight receiving means adapted to be mounted on the roof and to transmit sunlight therethrough, duct means for transmitting the sunlight beneath the roof and adjustable mounting means for connecting the duct to the sunlight receiving means.
BRIEF DESCRIPTION OF THE DRAWINGS
In order that the invention may be more readily understood and put into practical effect, reference will now be made to the accompanying drawings, in which:
FIG. 1 is a perspective view of a skylight assembly according to a preferred embodiment of the present invention,
FIG. 2 is a perspective view of the lower portion of the skylight assembly shown in FIG. 1,
FIG. 3 is a sectional side elevational view of the skylight assembly shown in FIG. 1 mounted on a roof having an inclination of 22.5 degrees,
FIG. 4 is a transverse cross-sectional view of the skylight assembly shown in of FIG. 1,
FIG. 5 is a perspective view of the sealing strip of the skylight assembly shown in FIG. 1,
FIG. 6 is an enlarged view of part of FIG. 4 showing the junction of the lower and upper portions of the skylight assembly,
FIG. 7 is a perspective view of the adjustable collar of the skylight assembly shown in FIG. 1,
FIG. 8 is an enlarged view of part of FIG. 3 showing the junction of the lower and upper portions of the skylight assembly,
FIG. 9 is a view similar to FIG. 3 showing the skylight assembly mounted on a flat roof, and,
FIG. 10 is a view similar to FIG. 3 showing the skylight assembly mounted on a roof having an inclination of 45 degrees.
DESCRIPTION OF BEST MODE OF PERFORMING THE INVENTION
The skylight assembly 10 shown in FIGS. 1 and 3, which is adapted for use with concrete roofing tiles, consists of a partly transparent sunlight receiving means in the form of a domed structure 11 that protrudes above the roof 12, a straight duct 13 (see FIG. 3) and an adjustable collar 14. The duct 13 may be of a concertina-type construction so as to allow for variable location of the domed structure 11 with respect to the room or the like beneath the roof 12 requiring illumination.
The domed structure 11 has an upper transparent portion 15 and a lower base 16. In this instance, the base 16 (shown separately in FIG. 2) includes an integrally moulded mounting platform 17, that is adapted to be sealingly mounted on the roof 12 (as shown particularly in FIG. 3, 9 and 10).
The adjustable collar 14 is located within the domed structure 11 and has a lip 25 at the top of the inner surface 20 against which the upper portion of the straight duct 13 abuts. The collar 14 and at least the upper portion of the duct 13 share a common symmetrical axis 18 which, in this instance, is vertical. The duct 13 is in light passage communication with a room or the like beneath the roof 12 requiring illumination.
The collar 14 has a pair of outwardly extending lugs 19 disposed at opposite sides thereof and which are adapted to be seated in a pair of diametrically opposed grooves 21 formed in the rim 22 of the base 16. The seating of the lugs 19 in the grooves 21 allows the collar 14 and the domed structure 11 to be rotatably adjusted with respect to one another about horizontal axis 26 (see FIGS. 3, 9 and 10).
