1. Field of the Invention
The present invention relates to an attachment for a toilet seat, and more particularly to a device attachable to the underside of the toilet seat to provide for lateral slide prevention of the toilet seat relative to, and interactive with, the rim of the toilet bowl.
2. Background of the Art
Conventional toilet seats hinged to a toilet bowl are supported in their lowered positions on the rim of the toilet bowl by at least two bumpers secured to the underside of the toilet seat or integrated therewith as part of the underside of the seat. Such bumpers are not effective, however, to prevent horizontal shift of the toilet seat under load from its position in alignment with the toilet bowl opening.
Various devices have been employed to address this problem. For example, U.S. Pat. No. 3,191,193 to Bogenberger is directed to a toilet seat attachment and discloses, inter alia, a device comprising a shallow fitting receivable within the space between the seat and the bowl and extending transversely beneath a portion of the seat. The fitting is connected to the seat by means of hood portions.
U.S. Pat. No. 4,747,167 to Adams is directed to a non-shiftable toilet seat assembly and discloses, inter alia, impact-absorbing bumpers contoured to be seated on the supporting surfaces of toilet bowl rims.
U.S. Pat. No. 7,536,732 to Dunlap is directed to a toilet seat shock absorption and slide prevention device and discloses, inter alia, a device removably attachable to the underside of the toilet seat for preventing the toilet seat from sliding back and forth and for providing shock absorption.
U.S. Publication No. 2012/0017947 to Hobbs is directed to a toilet seat stabilizer and discloses, inter alia, a laterally extending frat structure and an extended structure configured as a vertical downward protrusion.
There yet remains a problem in that the stabilizer device needs to conform to any of a variety of toilet bowl seat and rim configurations. The prior art devices have a predetermined shape and do not provide a device with lateral shift prevention adapted to conform itself to the shape and dimensions of a variety of toilet bowls.
Accordingly, provided herein is a toilet seat stabilizer assembly comprising a bumper fabricated from a thermoplastic polymer that is softenable in response to heat and moldable to a desired configuration while in a malleable condition; and means for attaching the bumper to a toilet seat.
The invention provides a stabilizer that can be accommodated to any commercial toilet bowl configuration and provides lateral stability.
A toilet seat stabilizer assembly is provided herein which comprises: (a) a bumper fabricated from a thermoplastic polymer which is softenable in response to heat and moldable while in a malleable condition to a desired configuration; and (b) attachment means for attaching the bumper to a toilet seat.
Also provided herein is a method for stabilizing a toilet seat using said assembly and a kit for containing the assembly. The kit including a container configured to heat soften the bumpers, at least two bumpers fabricated from a thermoplastic polymer which is softenable in response to heat and moldable while in a malleable state to a desired configuration, wherein the thermoplastic polymer has a softening point below 100 degrees Celsius and an attachment means for attaching the bumpers to a toilet seat. Other components can also be included in the kit.
Also provided is a method for stabilizing a toilet seat comprising the following steps, a) providing a toilet seat stabilizer assembly which includes a bumper fabricated from a thermoplastic polymer which is softenable in response to heat and moldable while in a malleable condition to a described configuration, and an attachment means for attaching the bumper to a toilet seat, wherein the thermoplastic polymer has a softening point below 100 degrees Celsius; b) heating the thermoplastic polymer to a temperature above its softening point; c) attaching the bumper to a bottom surface of the toilet seat; d) pressing the toilet seat door onto a rim of a toilet bowl with a force sufficient to conform the shape of the bumper to the rim of the toilet bowl; and, e) permitting the bumper to cool to a temperature below the softening point of the thermoplastic.
Various embodiments are described below with reference to the drawings wherein:
The toilet seat stabilizer of the present invention is adapted to retrofit to any typical commercially available toilet bowl for home or institutional use. Toilet bowl rims have various dimensions, but the toilet seat stabilizer of the invention includes a bumper that conforms to the rim of the toilet bowl to prevent lateral sliding.

In an alternative embodiment as shown in
In yet another embodiment as shown in
In an embodiment the bumper 111 is fabricated from a thermoplastic polymer that has a relatively low softening point such that it can be softened by exposure to heat of less than the boiling point of water. Such softenable thermoplastic polymers are known and typically employed for use as reformable mouth guards for athletes and those likely to sustain injuries to the teeth from various activities.
For example, a thermoplastic polymer suitable for use in the present invention is an ethylene vinyl acetate copolymer (EVA) commercially available from DuPont under the designation Elvax®. Also, the softenable material suitable for use in the present invention can comprise a blend of EVA and polycaprolactone. A suitable polycaprolactone is TONE® from Union Carbide Corporation, Danbury, Conn. However, the softenable material may consist of the polycaprolactone alone as the possibility of EVA alone may also be utilized.
Another embodiment of the softenable material may be a blend of polycaprolactone and polyolefin elastomer such as a copolymer of ethylene and octene-1. A suitable copolymer is available as ENGAGE® from Dupont Canada, Inc., Mississauga, Ontario L5M 2H3.
In an embodiment the softenable material can comprise a blend of EVA, polyvinyl acetate and polycaprolactone.
Various softenable material compositions are disclosed in U.S. Pat. Nos. 7,530,355, 6,987,140, 6,508,251 and 5,051,476, both of which are incorporated by reference herein. The thermoplastic polymer has a softening point of under 100 degrees Celsius, preferably under 80 degrees Celsius and more preferably under 70 degrees Celsius.
Typically, the thermoplastic polymer is softened by immersion in hot or boiling water until it is sufficiently softened. Alternatively, the thermoplastic polymer can be softened by directing a stream of hot air onto it, for example, by means of a portable hair dryer or heat gun. The softened bumper is then attached to the bottom surface 104 of the toilet seat 103 and the toilet seat is then pressed down upon the rim 102 of the toilet bowl 101. With sufficient pressure, the bumper 111 will then reform to the configuration of the toilet bowl rim 102, and then stiffen when cooled to ambient temperature. As shown in
