Telescoping spray wand assembly
First Claim
1. A telescoping wand assembly for use in dispensing liquid from a container, comprising:
- a) a trigger module extending along a longitudinal axis between proximal and distal ends and comprising a tubular handle member, a user accessible trigger positioned externally of said tubular handle member and selectively movable between first and second positions, a hose positioned within said tubular handle member and adapted to transport liquid from the container, and a valve actuating member that is selectively, movably actuable by movement of said trigger between its first and second positions;
b) a tube assembly interconnected to said handle memberc) a first tube interconnected to said handle member and comprising opposing first and second ends and a predetermined internal cross-sectional dimension;
d) a second tube positioned co-axially within said first tube and in fluid communication with said hose and comprising first and second ends and a predetermined external cross-sectional dimension, wherein said predetermined external cross-sectional dimension is less than said predetermined internal cross-sectional dimension of said first tube with a cross-sectional gap defined there between;
e) a third tube coupled in sealed relation to and in fluid communication with said second tube wherein said third tube is selectively slidably movable along said longitudinal axis towards and away from said trigger module;
f) a nozzle in fluid communication with said third tube; and
g) a valve mechanically linked to said first tube and positioned between said third tube and said nozzle and in spring biased relation to said nozzle for selective movement between a first position wherein said nozzle is sealed relative to said third tube and a second position wherein said nozzle is in fluid communication with said third tube, whereby selective movement of said trigger between its first and second positions causes said first tube to longitudinally move which in turn causes said valve to move between its first and second positions, respectively.

Abstract
The invention provides a telescoping wand assembly for use in dispensing liquid from a container, including a trigger module extending along a longitudinal axis between proximal and distal ends. The trigger module includes a tubular handle member, a user accessible trigger positioned externally of the tubular handle member that is selectively movable between first and second positions, a hose positioned within the tubular handle member and adapted to transport liquid from the container, and a valve actuating member that is selectively, movably actuable by movement of the trigger between its first and second positions. A stationary frame assembly provides rigidity and contact points for a telescopically movable tube assembly that extends from the trigger module. A shut-off valve and nozzle are positioned at the distal end of the wand assembly and movement of the shut-off valve is controlled by the trigger and translated by way of the tube assembly.
