Abstract

Abstract The plumbing line trap provided is fabricated from a deflectable type of plastic material and is easily cleaned once removed and placed in the cleaning position. Removal is facilitated by the construction of the two free ends of the return bend of the trap each of which includes a collar for retaining in place a resilient clamp which is loosened or tightened through the operation of an associated threaded fastener. The material from which the return bend is fabricated is preferably a high density polyethylene of a clear or transparent type which admits light and thus permits the home owner to readily determined whether or not cleaning is necessary or impending.

Claim 1
Independent Claim 201 words
A quick release trap for use in connection with waste water return plumbing lines, comprising: an arcuately curved pipe bend portion having a pair of upwardly disposed leg portions sized to receive a corresponding one of a pair of mating downwardly oriented pipes; each of said leg portions having a plurality of segmented and frangible end portions; a pair of clamps engageable over individual ones of said segmented end portions for attaching each respective leg portions to the opposed pipe; a threaded fastener engageable with opposed extending lips from each of said clamps for tightening each clamp about the associated segmented end portion for holding the bend portion tightly attached at both leg portions to the mating pipes; said bend portion and said leg portions all being constructed of a high density polyethylene substance for admitting light through their walls to make possible a visual inspection of the condition of the pipe bend preparatory to removal for cleaning; and each of said leg portions being readily and separately detachable from its opposed pipe and deflectible over a substantial distance whereby a water hose or other like cleaning instrument may be inserted for removing and dislodging clogging material from the bend portion.
