Spring-biased pivoting squeegee

Abstract

A spring-biased pivoting squeegeeprovides a headpivotally attached to a handle. The headis movable between a rest position, in which the headis angularly displaced from the handle, and a biased position in which the head, handle, and wiping bladeare in linear relation. In the biased position, the wiping blade is maintained at an optimum angle for cleaning a glass surface even with the handleheld generally perpendicular to the glass. A springis fully contained in the headand biases the head toward the rest position. A tension adjustment knobin the headpermits adjustment of the springto a tension level according to the ergonomic requirements of a user. In a second embodiment of the invention an improved locking mechanism comprises a pivoting lock leverheld against the top wallof a recessin the headof the squeegee by a retainer. The lockis movable between locked and released positions. In the locked position stop surfaceson the lock lever abut with upward facing ledgesof side plateson the forward portion of the main handle bodyto lock the headin the biased position. Two springshave forward projectionswhich rest in downwardly biased engagement on a spring pull nut. The spring pull nutis adjustable by turning an adjustment knobto modify the tension on the springs. Slip-resistant surfaces on the handleand headimproved handling of the squeegee.
