ABSTRACT:
THE FIELD OF THE INVENTION
The present invention relates to a multiple discharge faucet spout, which may be a part of a pullout faucet wand. The spout has both a stream discharge and a spray discharge. There is a movable valve member within the head of the spout which controls water flow to one or the other of the stream or spray discharges. The valve member is moved by pushing against a membrane at the top of the spout to change the valve member from its default position of a stream discharge to a spray discharge position. Upon water shutoff, the valve member returns, by the influence of a coil spring, to the stream discharge position. The top of the faucet spout includes a release member which, upon rotation, is effective to permit the valve member to return from the spray position to the stream position.
In prior faucet spouts, particularly of the wand type, there have been flexible elements which are used as the trigger to change the type of faucet discharge. It was not always possible in the prior art designs to return to a stream discharge from a spray without shutting off the water. Further, cosmetically, such triggers did not always appear to be a smooth and integral part of the wand shell, and there were often gaps between the trigger and the shell. The present invention provides a smooth appearing, gap-free faucet spout wand, with a flexible trigger, and an easily movable release member to return the faucet spout from a spray discharge to a stream discharge, even while water flow continues through the spout.
SUMMARY OF THE INVENTION
The present invention relates to a multiple discharge faucet spout and more specifically to such a spout in which a release member is utilized to return the spout to a stream discharge while water continues to flow through the spout.
A primary purpose of the invention is to provide a faucet spout of the type described using an elastomeric membrane to receive a manually applied force to change from a stream discharge to a spray discharge, with the cap supporting the membrane being rotatable and functioning as a release member to return to a stream position.
Another purpose of the invention is to provide a simply constructed reliable and compact trigger mechanism for controlling the type of discharge from a multiple discharge faucet spout.
Other purposes will appear in the ensuing specification, drawings and claims.
