Description

ILLUMINATING BRICK
FIELD OF THE INVENTION
This invention relates to the illumination of pathways, driveways, walkways and patios. Interlocking pathways are designed around houses and other buildings and can be very attractive in appearance. PRIOR ART
Illuminated bricks have previously been proposed but have suffered from the disadvantages that water collected in the interior of the brick and condensation collected on the inner surfaces. Furthermore, some prior illuminated bricks have been provided with screws to hold the top of the brick in place and these protruded above the top surface of the brick which is a disadvantage.
It is an object of the present invention to provide an improved brick device which has utility in illuminating an area and also enhances the appearance of the area.
There is provided a brick device comprising in combination a hollow simulated brick portion having a main body portion, a ledge within said main body portion around one open end, a light-emitting upper surface portion resting on said ledge to fit snugly and close said one open end, an electric bulb unit supported within said brick portion whereby, in use, light is transmitted through said upper surface, another end of said main body portion being open over a substantial part of its area to facilitate drainage and substantially reduce condensation.
According to the present invention there is provided a brick device comprising in combination a hollow simulated brick portion having a main body portion molded in one piece with a pair of opposing longitudinal side portions, a pair of opposing end portions, a base portion, and an open top, an integrally molded electric bulb support bracket portion on said base portion intermediate said pair of end portions, at least one aperture provided in said base portion, said base portion having at least one push-out portion in another aperture to provide a support platform for the brick portion in use and capable of being removed to provide a larger aperture space in said base portion, the aperture space in said base portion being such that the brick portion is open over a part of an area of said base portion to facilitate drainage and substantially reduce condensation, a ledge around said open top of said brick portion, a light-emitting upper surface portion resting on said ledge to fit snugly and close said open top, at least one retaining tab on an edge of said light-emitting upper surface portion, a corresponding aperture in said main body portion above said ledge for said one retaining tab to engage in when said light-emitting upper surface portion rests on said ledge.
The upper surface portion may be a sheet of transparent material supported on said ledge within said brick portion. DESCRIPTION OF THE DRAWINGS

Figure 9 is a perspective view of the bulb support member within the main body portion of the brick of Figure 4. DETAILED DESCRIPTION OF THE EMBODIMENTS
In the Figures the brick device 2 comprises a hollow simulated brick portion 4 formed from a urethane material. A molding technique may, of course, be used and it will be seen that a ledge 6 is provided around the inside of the simulated brick portion.
A light-emitting upper surface portion 8 rests on the ledge 6 and this may be regarded as a lens unit made of lexsand and coloured with epoxy and pigment to simulate a brick, for example an interlock brick. Different colors may be used for different lighting effects. The upper surface portion fits snugly to be a tight fit and a small screwdriver or other implement is necessary to pry it upwards. Thus, it will be difficult for children or animals to disturb it and the tight fit may be achieved by close tolerances during manufacture or other means. Furthermore, it will be understood that the lens unit may provide a clear lens (upper portion) for uplighting shrubs, etc., smoked lens, or a lens to simulate an interlocking brick.
The walls of the brick portion are, for example, 3/16 of an inch thick and are a little thicker on the top with a 45 degree angle under the leg where the top lens portion will be placed. The top lens portion 8 is 3% inches by 7% inches. It will be cut from a sheet of LEXSAND* and the color (pigment) and texture (epoxy) will
* Trademark be poured on top of the cut squares. The internal lower surface 10 of the brick portion will be open or partly open over a substantial part thereof whereby drainage of water can occur so as to avoid condensation.
The brick itself may be used in soldier bordering for interlock paving paths and for other purposes.
The simulated brick portion is molded with a protruding platform 12 (Figure 1) which is drilled so as to support a bulb 14. Wires 16 extend through the portion 12 to the bulb 14 and are connected to a 12-volt power supply system 18.
The light bulb 14 may be supported from a bracket on the interior surface of the simulated brick portion.
Referring to Figures 4 through 9, an embodiment of the invention is shown. The main body portion 20 of a brick is illustrated and will be seen to be molded with a pair of longitudinal side portions, a pair of opposing end portions, a base portion and an open top. The main body portion 20 is provided with a ledge 22 around the inside and a small slot 24 on each end to facilitate the use of a screwdriver, or other implement, to release the top lens portion as described below. On either side of each slot 24, an aperture 26 is provided to receive a retaining tab 32 (Figure 5) .
The external surface of the main body portion 20 is formed with slightly protruding rib members 28 for strength.
In Figures 5 and 6 the top lens portion 30 will be seen to be rectangular in shape to fit snugly within the top of the main body 20 resting on the ledge 22, At each end of the top lens portion 30, a pair of spaced-apart retaining tabs 32 is provided and during manufacture a slot 34 is formed between the tabs and, in use, each slot 34 will be in-line with a corresponding slot 24 in the main body portion 20 (Figure 4). In Figure 7 a cross-section of part of the body portion 20 is shown and the ledge 22 supports a downwardly protruding portion 36 of the top lens portion 30. The retaining tab 32 is relatively small and of triangular cross-section. Thus it can be readily snapped out of the aperture 26 by use of a suitable implement when it is wished to remove the top lens portion 30 from the main body portion 20.
In Figure 8 a plan view of the main body portion 20 is shown. An electric light bulb 38 is supported on an upstanding bracket 40 which is molded integrally with the base 42. The shape of the bracket 40 is shown in Figure 9 and is provided with an aperture 44 for mounting the light bulb socket 46. Wires 48 pass out of the brick to a suitable voltage supply system such as 18 in Figure 1.
The base 42 is molded of thin material and, in practice, the whole of the main body portion 20 is molded as one piece, for example of polypropylene. In some areas of the United States, such as California, the brick may be resting on a sandy underlay which would not support a brick with a completely open base. Thus the base 42 of Figure 8 is shown with fill-in/push-out portions 50 and 52 whilst still leaving a substantial part of the area of the base open to facilitate drainage and substantially reduce condensation. The push-out portions 50 and 52 are surrounded by openings 54 in the base which permit drainage through them when it is wished to retain portions 50 and 52, for example in California. In other parts, the portions 50 and 52 may be pushed out to provide an even greater area for drainage. Apertures 56 are also provided in the base for drainage purposes.
In some cases only one push-out portion, such as 50 or 52, may be provided. About 5% to 95% of the base area may be open to facilitate drainage and substantially reduce condensation.
Whilst the brick has been illustrated as of rectangular cross-section and cuboid in shape, it will be appreciated that it may be of any convenient shape. For example, bricks, such as stepping stones, may be of circular cross-section.
Furthermore, the upstanding bracket 40 may be of smaller size. It may be substantially rectangular and have a length about one-half the width of body portion 20 so that there is a space between each side of the bracket 40 and the nearest side portion of the body portion 20. This results in the reduction or elimination of the small shadow cast by the bulb 38 on the end wall portion of the body portion 20.
It will be observed that no screws are used in the described embodiments of the invention and no holes for pins.
The body portion 20 may be made of polypropylene and the lens portion 30 of polycarbonate to withstand vehicular traffic.
The top lens portion may be made of an acrylic-polycarbonate. LEXSAND is the trade name of one material used. In different climates, a different rate of expansion exists between the polycarbonate top lens portion and the main body portion. Thus special steps have to be taken to ensure a snug-fit for the top lens portion and the retaining tabs 32 assist in this regard if unexpected expansion takes place.
The brick may, for some purposes, be made of charcoal. Many illuminating brick colours are available, for example light brown, dark brown, red, charcoal and grey.
It will be readily apparent to a person skilled in the art that a number of variations and modifications can be made without departing from the true spirit of the invention which will now be pointed out in the appended claims.
