Abstract
A central spindle which at the base end is eccentric. The central spindle is surrounded by a sleeve which is deformed and expands its effective diameter at the base when the spindle is turned. To release, the spindle is turned in the opposite direction, and the seat assembly may be removed. The device is particularly useful for attaching a toilet seat.

A quick release toilet seat assembly comprising:
- a toilet seat fastener comprising a base having an attachment aperture therethrough;
- a sleeve having an eccentric split oval bore therein, said sleeve having an axis substantially parallel to length of said sleeve and an upper flange, said sleeve having an outer perimeter smaller than said aperture, said sleeve being placed in said aperture;
- a spindle having an elongated eccentric section, and an axis concentric with said bore axis, located in said eccentric bore whereby when said spindle is rotated in said bore said sleeve is deformed to exert pressure radially from said concentric axis along the length of the sleeve.
A fastener comprising:
- a sleeve having an eccentric split oval bore therein, said sleeve having an axis substantially parallel to the length of said sleeve;
- and
- a spindle having at least two eccentric cross sections thereon placed within said sleeve, said cross sections being vertically separated by a section of said spindle having cross-sectional area less than the cross-sectional area of either of said eccentric cross sections, and an axis concentric with said bore axis located in said eccentric bore whereby when said spindle is rotated in said bore said sleeve is deformed to exert pressure radially from said concentric axis.
A quick release toilet seat assembly comprising:
- a toilet seat fastener comprising a base having an attachment aperture therethrough;
- a sleeve having an eccentric bore therein, said sleeve having an axis substantially parallel to the length of said sleeve and an upper flange, said sleeve having an outer perimeter smaller than said aperture, said sleeve being placed in said aperture;
- a spindle having an elongated eccentric section thereon placed with said sleeve, and an axis concentric with said bore axis, located in said eccentric bore whereby when said spindle is rotated in said bore said sleeve is deformed to exert pressure radially from said concentric axis along the length the sleeve;
- said base further having means for supporting said flange;
- an arm having two ends, said arm being connected to a toilet seat at one end and having a retaining means connected on the other end;
- and
- an arm retainer formed within said base for holding said retaining means,
- wherein said retainer further comprises:
- a top in connection with said base, said means for supporting said flange comprises a retaining ledge for said flange, wherein said top further comprises a spindle aperture for receipt of said spindle, wherein said top and base are provided with mating channels for retaining said retaining means.
