Abstract
Abstract A heated bed module for use by animals, consists of a box-like unit having an animal supporting top panel and a shallow liquid containing chamber immediately below the top panel. A thermostatically controlled heater is installed below the liquid chamber with suitable support and insulation and access is provided for filling and draining the chamber. The unit is completely self-contained and used alone or coupled to other units to make a heated assembly for any size of animal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
156 words
A heated bed module for animals, comprising: a unitary, substantially rigid box-like frame having a planar animal supporting top panel, with surrounding side walls depending therefrom, and a removable bottom panel secured to said side walls; a rigid inner panel spaced below said top panel and sealed to said side walls to enclose a shallow liquid containing chamber; said chamber having access means for filling and draining said chamber; said frame having a lower housing extending below said chamber and enclosed by said bottom panel; a rigid support member within said lower housing spaced above said bottom panel; a thermally conductive electrical insulation layer immediately below said inner panel; a thermostatically controlled heater mounted between said support member and said electrical insulation layer; thermal insulation substantially filling said lower chamber below said support member; said top panel, said inner panel, and said support member being substantially parallel to one another and having substantially equal surface areas.
