Lake & Co Imperial House, 15-19 Kingsway, LONDON, WC2B BUD, United Kingdom
a APPARATUS FOR ILLUMINATING AND/OR VENTING THE INTERIOR
OF A BUILDING
This invention relates to apparatus for illuminating 5 and/or venting the interior of a building and particularly, although not exclusively, relates to skylights and/or roof vents.
When domestic or commercial roof spaces are used as 10 living accommodation, storage or office space, it is preferable that they are at least partially lit by natural light. Sometimes this is achieved by fitting Velux (registered trade mark) or Dormer windows.
Although modern Velux and Dormer windows are functional 15 and attractive, planning permission for such structures on a roof is sometimes refused, or they are considered undesirable by the owner of the building. In such circumstances, it is known to provide a skylight comprising a light reflective tube which passes through 20 the roof and projects above the level of the roof. The tube is capped by a light transmissive cover which projects still further above the surface of the roof.
The whole assembly is unnecessarily cumbersome and unsightly. STATEMENTS OF INVENTION
According to a first aspect of the present invention there is provided apparatus for illuminating the 30 interior of a building through a roof of the building, the apparatus comprising a light transmissive panel which has an upper surface which is substantially identical in shape to an upper surface of a roof covering and which lies in the plane of the said
covering, and a light directing duct which directs light from the panel into the interior of the building.
Preferably, the light directing duct is fitted to an 5 underside of the panel. Most preferably the light directing duct is sealed to an underside of the panel.
For example it may be attached permanently with adhesive or a sealant and/or may be sealed with a resilient gasket.
Preferably, the upper surface of the panel is flush with an upper surface of the covering.
Preferably, the covering comprises roof tiles, 15 shingles, slates or roofing sheets and the panel matches the contour and spacing of one or more roof tiles, shingles, slates or roofing sheets.
Preferably, the panel comprises a first light 20 transmissive portion which is aligned with the light directing duct and an opaque portion. Preferably, the opaque portion is coloured and/or textured to match the roof covering.
25 Preferably, the duct passes through an underlay layer of the roof. The underlay layer may be sealed to an outer surface of the duct. For example, it may be sealed with a resilient gasket.
30 Preferably, the panel further comprises an air vent for allowing air from outside the roof to circulate through the duct. Preferably, an upper section of the duct includes apertures which allow the air to pass into and out of the duct.
Preferably, a lower end of the duct is provided with a light transmissive cover. Preferably, at least part of the panel and/or the cover are transparent or 5 translucent. Preferably, the panel and/or the cover are made from a plastics material such as polycarbonate. It is well known that the temperature difference 10 between the outside of a roof and the roof space beneath the roof can cause a build up of condensation within the roof space. This problem can be alleviated by venting the roof, so that fresh outside air flows across the roof space, thereby reducing the temperature 15 within the roof space and reducing the humidity. It is known to vent roofs through vents provided under the eaves or above the weather boarding. This can provide some limited through flow of air, but the venting is greatly improved if vents are also provided along the 20 ridge line of the roof. Conventional ridge vents project above the level of the roof and are unsightly.
According to a second aspect of the present invention, there is provided apparatus for venting the interior of 25 a building, the apparatus comprising a venting panel having at least one venting channel, and having an upper surface which is substantially identical in shape to, and lies in the plane of, an outer covering of the building, the interior of the building being vented 30 through the panel.
Preferably, the outer covering is a roof covering of the building such as tiles, shingles, slates or roofing sheets.
The venting channel may comprise a flow passage formed in or attached to the venting panel.
5 Preferably, the venting channel comprises an inlet at an edge of the panel and a plurality of air directing fins associated with the inlet. Preferably, a portion of at least one of the fins is offset relative to the inlet or is curved, to prevent rainwater entering the 10 inlet. At least one of the fins may have a corrugated profile, and may extend in a direction substantially perpendicular to the inlet.
Preferably, a duct is provided which is in fluid 15 communication with the channel formed in the roof tile, the duct passing into the interior of the building.
Preferably a fan is provided which is adapted to assist the flow of air through the panel and/or the duct.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Figures 1 and 2 show a first embodiment of skylight 1 comprising a cylindrical housing 2 fitted into a 5 cylindrical opening 4 formed in a tile 6. The cylindrical housing 2 is provided with an annular flange 8 which sits in a recess 10 formed in an upper surface of the tile 6 and prevents the cylindrical housing 2 slipping through the tile 6 in service. The lo cylindrical housing 2 and annular flange 8 are sealed to the tile 6 by means of adhesive, sealant or a sealing gasket arrangement (not shown) so that the joint between the cylindrical housing 2 and tile 6 is weatherproof. The cylindrical housing 2 projects from the bottom of the tile 6 and is connected to a cylindrical light directing duct 12. In the illustrated embodiment, and the cylindrical housing 2 is closely received within an 20 end of the light directing duct 12. The joint between the cylindrical housing 2 and light directing duct 12 is sealed by flexible sealant. However, the cylindrical housing 2 and light directing duct 12 may be of any desired shape and may be interconnected in 25 any conventional manner. For example, the external diameter of the light directing duct 12 may be smaller than the internal diameter of the cylindrical housing 2 so that the light directing duct 12 is received within the cylindrical housing 2. Such an arrangement would 30 be inherently more weatherproof, since rainwater could not easily penetrate the gap between the cylindrical housing 2 and light directing duct 12.
The upper end of the cylindrical housing 2 is sealed off by a light transmissive element 14 which forms, with the tile 6, a light transmissive panel 13. The opposite end of the light directing duct 12 is closed 5 off by a light transmissive cover 16. Furthermore, the inside surface 17 of the light directing duct 12 and/or the cylindrical housing 2 is coated with light reflecting material, such is used in a conventional lamp reflector.
The light transmissive element 14 and light transmissive cover 16 may be formed from any transparent or translucent material, such as Perspex or polycarbonate. Furthermore, the tile 6 may be replaced 15 with an artificial tile so that the cylindrical housing 2 and tile 6 may be moulded together as an integral unit. Indeed, if the artificial tile 6 is made of light transmissive material, such as Perspex or polycarbonate, the cylindrical housing 2, tile 6 and 20 light transmissive element 14 can be integrally moulded together to form the light transmissive panel 13. The portion of the artificial tile 6 which does not need to be light transmissive can be opaqued by means of painting or the addition of a surface finish, so that 25 it matches the surrounding roof tiles.
In an alternative embodiment (not shown) the cylindrical housing 2, light directing duct 12, light transmissive element 14 and light transmissive cover 16 30 could be formed together as a sealed evacuated or gas filed unit. In such a sealed arrangement, condensation within the unit would not be a problem. However, in the embodiment of Figures 1 and 2, in which the cylindrical housing 2 is separate from the light
directing duct 12, it is preferable to include vent holes 18 which are open to the ambient air circulating beneath the tile 6. The vent holes allow the ambient air to circulate through the space between the light 5 transmissive element 14 and light transmissive cover 16 and prevent a build up of condensation within the unit.
The skylight 1 is attached to a roof by removing a section of roof tiles to gain access to an underlay 10 layer 20. A hole is formed through the underlay layer 20 through which is fitted the light directing duct 12.
The duct is sealed to the underlay layer by means for a gasket 22. The tile 6 is then lowered into position, such that the cylindrical housing 2 fits within the 15 light directing duct 12, and the gap between the two is sealed with flexible sealant. Finally, the surrounding tiles are made good.
As the skylight is located within a tile or artificial 20 tile, when installed, and does not project above the upper surface of the tile the surface profile of the roof is maintained and all that is visible from the outside of the roof is the light transmissive element 14. Figure 3 shows an alternative arrangement in which a single large light transmissive element 14 is fitted within a light transmissive panel 13 which is shaped to simulate four separate roof tiles, although it is 30 integrally moulded as a single element. This is achieved by moulding into the panel 13 a step 22 to simulate the joint between upper and lower tiles and a groove 24 to simulate the gap between tiles laid side by side.
Figure 4 shows a further embodiment in which a single integrally formed light transmissive panel 13 is moulded to simulate four separate tiles and includes 5 four individual light transmissive elements 14. The embodiments illustrated in Figures 3 and 4 increase the amount of light which is directed into a space beneath the roof for the minimal additional effort in fitting the skylight.
Figure 5 shows an alternative embodiment of skylight in which the light transmissive element 14, the cylindrical housing 2 and the annular flange 8 are integrally formed together from light transmissive 15 material and are inserted into a real or artificial tile 6 to form the light transmissive panel 13. As in the embodiment of Figures 1 and 2, vent holes 18 are formed in the cylindrical housing 2 and the base of the cylindrical housing 2 is adapted to receive a light 20 directing duct 12.
Figures 6 and 7 show a further embodiment of skylight 1 in which the light transmissive panel 13 is formed by the roof covering itself. More specifically, the light 25 transmissive panel 13 comprises a conventional corrugated polycarbonate roofing panel 26 to which the cylindrical housing 2 is fitted by means of adhesive or sealant applied to the flange 8. As in the previous embodiments, a separate light directing duct 12 is 30 connected to the cylindrical housing 2, but in this embodiment it is received within the cylindrical housing 2.
In order to ensure an adequate seal between the roofing panel 26 and the cylindrical housing 2 the upper edge of the cylindrical housing 2 is shaped to accommodate the corrugations of the roofing panel 26.
Figures 8 to 12 show a roof vent 30 in accordance with a second aspect of the present invention. The roof vent comprises a panel 32 which may be opaque (Figure 9) or wholly or partially light transmissive (Figure 10 10) , and has an upper surface which is substantially identical in shape to, and lies in the plane of an outer covering of a roof.
Referring specifically to Figures 8 and 10, the panel 15 32 is formed from plastics material and is moulded in the shape of a conventional roof tile on its upper surface and in the regions 34, 36 which are adapted to engage with other tiles on the roof. However, the underside of the panel 32 at its lower edge 38 is 20 formed with a series of fins or baffles 40. The baffles 40 project at right angles from the underside of the panel 32 and extend downwards as far as an underlying tile 42, so that vent channels 44 are defined between respective pairs of baffles 40.
In the Figure 8 embodiment, the panel 32 is formed entirely from polycarbonate. The upper surface of the panel 32 is coated in the regions 44, 46, so that these regions are opaque and substantially match the 30 appearance of neighbouring tiles on the roof. The circular portion of the upper surface of the panel 32 between the opaque portions 44, 46 is left transparent and acts as a light transmitting element 48. Beneath the light transmitting element 48 is fitted a
cylindrical housing 50 which is sealed to the panel 32 by means of an annular flange 52. A cylindrical light directing duct 54 is closely received within the cylindrical housing 50 and is held in position by 5 adhesive or sealant.
Vent holes 56 are formed through the cylindrical housing 50 and light directing duct 54 and a vent passage 57 is formed in the panel 32 between the 10 baffles 40 and the cylindrical housing 50. The interior of the light directing duct 54 is held in fluid communication with the vent channels 44 formed in the underside of the panel 32 via the vent holes 56 and the vent passage 57.
If the lower end of the light directing duct 54 is closed by a transparent or translucent cover, the vents merely operate to prevent condensation within the light directing duct 54. However, if the lower end of the 20 light directing duct 54 is left open, or additional vent holes are provided at a lower end of the light directing duct 54, ambient air is able to pass from the vent channels 42 into the roof space, via the vent holes 56 and the light directing duct 54. Thus, vent 25 panel 32 can be used either with a skylight assembly, or on its own as a means of venting a roof or loft space. Figure 11 shows an alternative embodiment in which the 30 lower end 38 of the panel 32 is formed as a hollow tube having an upper wall 58 and a lower wall 60, which are spaced apart by a plurality of staggered rows of posts 62. The upper wall 58, lower wall 60 and posts 62 define a tortuous flow path P for air entering the
panel 32, so that rain is unable to find a direct path and is prevented from penetrating beyond the first few rows of posts 62 of the panel 32.
5 Figures 12a and 12b show a further embodiment in which the lower end 38 of the panel 32 is provided with an upper wall 58 and a lower wall 60 spaced apart by baffles 64 which are corrugated in cross section.
These baffles 64 act in the same way as the posts 62, lo since they force air entering the panel 32 to follow a tortuous path P which prevents the ingress of rain.
