Abstract

Abstract A novel integrated aquarium is disclosed wherein all of the necessary mechanical functions (air pump, lighting, heating) are located in a compartment provided as part of the aquarium base and those components particularly subject to mechanical failure are mounted in a slide-out drawer provided as part of said base so that they may be more easily repaired or replaced. In the preferred embodiment disclosed, an incandescent light bulb located in said base furnishes both light and heat to the aquarium and is controlled by a thermal sensor with a manual lamp socket over-ride switch provided. To facilitate removal of the air pump for maintenance and possible replacement, the air supply tube leading from the air pump to a sparger/riser tube assembly associated with an undergravel filter is removably connectable to a passageway communicating with said sparger/riser tube by means of a rubber air cup. A one-way check valve is provided as part of said sparger/riser assembly to prevent backflow of water into said compartment. The preferred embodiment disclosed is of an especially pleasing aesthetic hexagonal design and has a thin, unobstructive cover instead of the usual bulky light reflector hood mounted on the aquarium top.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 178 words
A frameless integrated aquarium comprising: a molded base defining a lower portion of a water containing region, said base being integrally provided with electrical means for heating, illuminating, and circulating the water contained in said water containing region; a plurality of transparent vertical side walls further defining said water containing region, said side walls being secured in part by integrally molded grooves provided as part of said molded base; a molded top frame having defined on the lower surfaces therof integrally molded grooves for further securing said side walls; and a false bottom removably located at the lower portion of the water containing region defined by said base and said side walls, said false bottom comprising: a vertically upstanding gravel barrier for permitting a light source located below said false bottom to project light into the interior of said water containing region above said false bottom, and a riser tube for permitting water to circulate upwards from the region below said false bottom, wherein at least a portion of said false bottom functions as an undergravel filter plate.
Claim 2
Dependent Claim 178 words
A frameless integrated aquarium comprising: a molded base defining a lower portion of a water containing region, said base being integrally provided with electrical means for heating, illuminating, and circulating the water contained in said water containing region; a plurality of transparent vertical side walls further defining said water containing region, said side walls being secured in part by integrally molded grooves provided as part of said molded base; a molded top frame having defined on the lower surfaces therof integrally molded grooves for further securing said side walls; and a false bottom removably located at the lower portion of the water containing region defined by said base and said side walls, said false bottom comprising: a vertically upstanding gravel barrier for permitting a light source located below said false bottom to project light into the interior of said water containing region above said false bottom, and a riser tube for permitting water to circulate upwards from the region below said false bottom, wherein at least a portion of said false bottom functions as an undergravel filter plate.
Claim 3
Dependent Claim 47 words
The integrated aquarium of claim 1 wherein said lighting means comprises an incandescent light bulb of generally tubular construction located in the portion of said base below said gravel barrier provided as part of said false bottom when said false bottom is in place inside said aquarium.
