Extendable handle, cleaning device and cleaning heads

摘要

A cleaning device for delivering a fluid under pressure onto a surface includes a head movable on the surface for spraying the fluid and an extendable handle for controlling placement of the head. The extendable handle has a pair of sets of members arranged in telescoping relation for movement between at-rest and extended positions. One of the members is defined by a pair of sets of articulated parts with one of the articulated parts extending exteriorly of the other of the members when the member sets are in the extended position thereof. A set of resiliently urged detents releasably retain the member sets against displacement from the at-rest position thereof, and a set of pawls are operable in response to pivotal movement of the one articulated part for interlocking the other of the articulated parts and the other of the member when the member sets are in their extended positions thereof.
