Urinal outlet assembly

Abstract

A urinal outlet assembly comprises a urinal outlet pipe and a connector for coupling the outlet pipe to a waste pipe inlet. The connector is adapted to receive the outlet pipe in a sliding sealing fit.

Description

[0001] This present application claims all available benefit, under 35 U.S.C. §119(b), of Utility Patent Application No. GB0422136.2, filed in the United Kingdom on Oct. 6, 2004. FIELD OF THE INVENTION [0002] This invention relates to a urinal outlet assembly, and to a connection for coupling a urinal outlet to a waste pipe. BACKGROUND OF THE INVENTION [0003] Conventionally, the waste pipe leading from a urinal is coupled to the soil pipe system via exposed plumbing, that is piping and water traps which are visible to a washroom user. However, there is increasing demand for the provision of urinals in which the plumbing is concealed. [0004] In one arrangement a “low profile” water trap is concealed within a recess in the rear face of the urinal. Such water traps feature a hollow body having a centrally located inlet in a front face, which inlet is provided with a seal arrangement and connects directly to the urinal outlet. The trap outlet pipe extends from a lower part of the body a...

AI Technical Summary

Benefits of technology

[0012] In use, the connector may be coupled to a waste pipe inlet by any appropriate means. The urinal outlet pipe may then be slid into the connector. The provision of a sliding sealing fit between the connector and the outlet pipe provides a degree of flexibility in the relative axial location of the connector and the urinal, such that the location of the connector, and thus the waste pipe inlet, becomes less critical than in conventional coupling arrangements. Also, the provision of the sliding sealing fit facilitates making up of the connection; in a preferred embodiment, all that is required is for the end of the outlet pipe to be located in the open end of the connector and the urinal then moved rearwards to push the outlet pipe into the connector. Once the end of the outlet pipe has been correctly located in the open end of the connector an operator involved in fitting the urinal may then concentrate on other matters, such as correctly and securely mounting the urinal on the supporting wall.

[0015] Preferably, the connector is adapted to engage with, but need not be a tight fit on, the waste pipe inlet. This facilitates making up the connection between the connector and the waste pipe inlet, and is particularly useful when the connection is relatively inaccessible, for example within a wall opening. The end of the connector may be adapted to be received in the waste pipe inlet, or may be adapted to receive the waste pipe inlet. The connector may be adapted to be solvent welded, glued or otherwise permanently fixed to the waste pipe.

Problems solved by technology

Furthermore, the coupling of the trap outlet pipe to the waste pipe inlet is problematic, given that the coupling location is within the wall and is intentionally concealed behind the trap and the urinal.
