Abstract
A stackable self-aligning and self-sealing plastic spacer for extending a soil pipe flange to floor level to meet a toilet fixture has a ring-shaped spacer with a tapered inner collar protruding from its surface. The collar is received within the similarly tapered central opening of the next adjoining spacer. The spacers are made of resilient plastic to provide a wedging fit that seals the joint against leakage.
Claims5
A stackable self-aligning and self-sealing spacer for extending a soil pipe flange to floor level to meet a toilet fixture, said spacer being characterized by:
- a ring-shaped body sized to cover a soil pipe flange and having spaced fastener openings circumferentially disposed for receiving threaded fastening means to interconnect said soil pipe flange, spacer and toilet fixture,
- said body being defined by parallel surfaces intersected by a conical opening corresponding to the inner diameter of the smallest soil pipe flange to be accommodated, said opening having a wide end and a narrow end,
- said body including an axially protruding elastically deformable annular collar defining an axial extension of the narrow end of said conical opening, and
- said collar having an outer conical surface adapted to be received in wedging self-centering sealing relationship with the conical opening of a second spacer of like construction when the spacers are assembled in stacked relationship about a common axis.
