DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 shows house-shaped mailbox enclosure 1. House-shaped mailbox enclosure 1 has the general appearance of a house or other building and may be constructed from a rigid material such as plastic, wood or metal. Mailbox enclosure 1 may be secured to a pole or to a house or otherwise located to provide access to postal carriers and recipients.
House-shaped mailbox enclosure 1 includes a front portion 2, a rear portion 3, at least two side portions 4, a roof portion 5 and a bottom portion (not shown).
Translucent windows 6 are disposed on house-shaped mailbox enclosure 1, simulating the windows on a house. As shown in FIG. 1 translucent windows 6 may be located on front portion 2, side portion 4 and/or roof portion 5 of house-shaped mailbox enclosure 1. Additionally, translucent windows 6 may be disposed on rear portion 3.
Translucent windows 6 are comprised of a material which transmits light to a degree such that light from an illumination source disposed inside mailbox enclosure 1 is visible from outside of mailbox enclosure 1 but an interior of mailbox enclosure 1 is not visible from outside through translucent windows 6. For example, translucent windows 6 may include plastic, frosted glass or any other suitable semi-transparent material.
A solar cell 7 may be disposed on house-shaped mailbox enclosure 1. As shown in FIGS. 1 and 2, solar cell 7 is preferably disposed on roof portion 5 of house-shaped mailbox enclosure 1. A photoelectric light sensor 8 may also be disposed on house-shaped mailbox enclosure 1, preferably on roof portion 5.
A power supply 9 and a light source 10 are disposed on an interior of house-shaped mailbox enclosure 1, as shown in the cut-away portion of FIG. 2. Power supply 9 provides energy to illuminate light source 10. Power supply 9 may comprise, for example, a rechargeable battery. An additional back-up battery may also be provided for powering light source 10 if a primary battery runs down.
Light source 10 may comprise, for example, an incandescent light bulb, a neon light bulb or a light emitting diode. When illuminated, light source 10 may provide visible light in an interior of house-shaped mailbox enclosure 1 to assist in viewing the contents thereof during hours of darkness or when ambient conditions are otherwise darkened. Light from light source 10 is transmitted through translucent windows 6, providing a pleasing aesthetic appearance to house-shaped mailbox enclosure 1.
In this way light source 10 in combination with translucent windows 6 provide an appealing aesthetic appearance when a lighted mailbox according to an embodiment of the present invention is viewed from outside, while maintaining a degree of privacy and security by preventing persons from observing the contents or lack thereof of the mailbox enclosure from outside. Light source 10 in combination with translucent windows 6 also provide a sense of security and safety when retrieving mail or other contents of mailbox enclosure 1 during hours of darkness.
Power supply 9 and/or light source 10 may be detachably secured to a housing 11 which is secured to an interior of house-shaped mailbox enclosure 1. Both power supply 9 and light source 10 are configured to be easily accessed and removed for repair or replacement.
A portion of house-shaped mailbox enclosure 1 is adapted to be opened and closed, thereby providing access to an interior of mailbox enclosure 1 by postal carriers and recipients. As shown in FIG. 2, for example, front portion 2 of house-shaped mailbox enclosure 1 may be swung open and closed, permitting access to an interior of the mailbox enclosure. Hinges, slides, latches and other mechanical means known in the art may be used for detachably securing front portion 2 to mailbox enclosure 1. A switch 13, for example a pin switch or a tilt switch, may be provided which is electrically coupled to power supply 9 and light source 10 such that light source 10 is illuminated only when front portion 2 is in an open position FIG. 3 is a schematic diagram of a circuit which may be used with house-shaped mailbox enclosure 1. The circuit includes solar cell 7 which is electrically coupled to power supply 9. Power supply 9 may comprise, for example, a rechargeable battery. The circuit shown schematically in FIG. 3 also includes photoelectric light sensor 8 and light source 10. Solar cell 7 uses light energy accumulated during daylight hours to charge power supply 9.
Photoelectric light sensor 8 interrupts a flow of energy to light source 10 such that light source 10 is not illuminated when a level of outside ambient light detected is above a determined level. For example, photoelectric light sensor 8 may interrupt a flow of current to light source 10 during daylight hours. Additionally, photoelectric light sensor 8 allows energy to flow to light source 10 when a level of outside ambient light is below a determined level, thus illuminating light source 10. For example, photoelectric light sensor 8 may cause illumination of light source 10 during nighttime hours. Additionally, manual override switch 12, shown in FIG. 2, may be provided which bypasses photoelectric light sensor 8 and permits manual control of illumination of light source 10.
Accordingly, while several embodiments of the present invention have been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
