Patent ID: 8800075

Claim:
A docking assembly for a pull-out sprayhead extendable from an aperture at a distal end of a faucet spout, comprising: a receptacle fitted within said spout aperture, said receptacle defined as a generally annular member having a longitudinal axis, said receptacle having an interior surface chamfered down to a constricted opening at said spout aperture; a resilient collet contained within said receptacle and adapted for travel along said longitudinal axis from a first position wherein said interior surface allows radial expansion of said collet to a second position wherein said constricted opening inhibits radial expansion of said collet; a spring within said receptacle and engaged to said collet, said spring biasing said collet into said second position; and a fitting attached to said pull-out sprayhead, said fitting comprising an annular member for cooperative insertion into and removal from said receptacle and a distal end for engagement with said collet, whereby insertion of said distal end with sufficient force to overcome said spring-bias moves said collet to said first position allowing radial expansion of said collet to facilitate said engagement, after which said spring-bias returns said collet to said second position whereby the inhibited radial expansion of said collet requires a relatively greater force to disengage said distal end from said collet and remove said sprayhead from said spout.
