Abstract
A paint pump cart having a telescoping handle assembly including a paint pump frame having a pair of standtubes, a handle having a pair of extensions received in the standtubes, and a pair of knobs mounted on the standtubes. Each knob is rotationally movable with respect to its standtube and has a pair of internal ramps. The handle assembly has a bushing supporting and retaining the knob while permitting movement of the knob on the standtube. A pair of resiliently mounted projections internal to the handle extensions are movable by the ramps of the knob between a locking position wherein the respective handle extension is maintained in an extended position with respect to the standtube, and a released position wherein the handle extension is allowed to telescope into the standtube towards a storage position.
