摘要: A spring-biased pivoting squeegee to a handle. The head (12) is movable between rest position, in which the angularly displaced from handle (16) and biased position (12), (16), wiping blade (14) are linear relation. In maintained at an optimum angle for cleaning glass surface even with held generally perpendicular glass. spring (60) fully contained biases toward position. tension adjustment knob (80) permits of level according ergonomic requirements user. second embodiment invention improved locking mechanism comprises lock lever (260) against top wall (262) recess (202) by retainer (278). locked released positions. stop surfaces (276) on abut upward facing ledges (256) side plates (250) forward portion main body (208) Two springs (306) have projections (308) downwardly engagement pull nut (304). adjustable turning (294) modify springs. Slip-resistant improve handling squeegee.
