Clip on cover for sink traps

Abstract

A clip on cover for sink traps is provided to allow prevention of burns to the legs of wheelchair users of the sink through isolating the trap at a distance from the cover and thus at a distance from the legs of the wheel chair user. The cover enables a range of form factors to be covered without the collection of leak water, allows leaks in the trap to be detected, and provides aesthetic flexibility and access for trap hygiene maintenance. The clip on cover enables easy cleaning and access for trap maintenance. By linking the weight of the trap indirectly to the sink mount through placement of clips such that the upper clip engages the fixed drain plug and the lower drain plug engages the trap upstream arm, strain on the downstream, horizontal, wall bend is relieved.

The design intention of trap covers is to prevent the legs and knees of a wheelchair user using a sink from suffering skin burns owing to not being able to sense the hot temperature of drainage water passing from the sink vessel, around th...

AI Technical Summary

Benefits of technology

[0015]The Invention, a clip on cover for sink traps, presents a cover for the trap which is clipped onto the vertical portion of the upstream part of the trap by means of a plurality of clips that fit onto the trap. An uppermost clip fits to the diameter of the threaded drain plug. Optional support by a nut adds an advantage over any other slip joint trap by allowing the Invention to also act as a trap support and relieve the weight of the trap from the wall bend. This requires another clip to clip onto the upstream arm of the trap itself. In order that water not collect, a substantial drainage cavity is provided in the base of the cover sized to avoid blockage.

[0016]By use of appropriate spacers between the plurality of clips and the cover, the Invention achieves trap cover the first design objective by providing airspace between the trap and the cover, preventing burns. The invention satisfies the second cover design objective two through providing an easily wiped trap cover, to prevent dust collection on the trap. The clips allow easy removal and replacement, to enable removal of a trap cleanout such as a detachable U-bend, to enable maintenance as in the third trap cover design objective. Through provision of a substantial drainage cavity freely allows water dripping from a perforated trap to drip to the floor to provide evidence of trap failure, allowing attainment of the fourth design objective. Trap cover design objective five is achieved since there is no potential for a secondary pool for water to collect. Trap cover design objective six is achieved by provision to fit a variety of trap designs and technologies. The clip on design also allows for a diversity of covers to be used independent of the form factor of the underlying trap.

Problems solved by technology

Accordingly, it is an objection of this Invention to at least partially overcome some of the disadvantages of the prior art.
