Abstract
Abstract Usual ventilating toilet devices require a relatively expensive vent system built into the seat unit or an attachment to the seat unit which has to be custom-designed for specific toilet bowl constructions. This means that they are not universal in attachment and are therefore relatively expensive. The present device is a horseshoe-shaped pad with air intake grooves on the underside and which can be engaged upon the bowl of the toilet between the bowl and the seat. A suction housing at the rear includes a sliding drawer at the front which can be adjusted to align with the rear curvature of the bowl and which can control the degree of suction to the bowl. The outlet on the side of the housing can readily be fitted upon either side depending upon installation requirements. The side not used is closed off with a sliding drawer or panel which can be used for access for cleaning, for insertion of deodorant material or the like, and to further control the degree of suction within the toilet bowl.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
A toilet ventilating device for toilet bowls which include an upper open side and a rear planar portion behind said upper open side; comprising in combination a substantially horseshoe-shaped element engageable upon said upper open side of said bowl, a suction housing secured to the ends of said elements and engageable upon said rear planar portion; conduit means connected to said suction housing operatively connected to a source of negative air pressure, and air intake means in said suction housing connecting to the interior of said bowl when said device is in position upon said bowl, means to control the degree of communication between the interior of the bowl and the interior of the suction housing via said air intake means in said suction housing, said means to control the degree of communication including a drawer component slidably engaging within the front of said suction housing and extending into said suction housing, and means in said drawer component communicating between the interior of said suction housing and said bowl, the degree of communication depending upon the position of said drawer component with said suction housing.
