Abstract
Abstract A squeegee or like cleaning appliance, particularly for cleaning window panes and floors, comprises a holder attached to a handle for removably holding a cleaning element of which one edge is held in a U-section mount. The holder comprises two clamping jaws of which at least one is movable for gripping the mount of the cleaning element between them, a clamping lever being hingeably attached to one of the clamping jaws and having a handle portion which projects through a window in the said clamping jaw. The handle portion is manually operable to wedge the lever against the other of the clamping jaws for locking the same in gripping position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
269 words
A squeegee, particularly for cleaning window panes and floors, comprising a. an exchangeable substantially strip-shaped cleaning element, b. first and second clamping jaws, c. means for pivotally securing said clamping jaws together for movement about a fulcrum, d. gripping means on each of said first and second clamping jaws on one side of said fulcrum for gripping opposite sides of said cleaning element, e. an aperture in said first clamping jaw, f. a clamping lever having a generally U-shaped configuration and including a handle portion at one end thereof, g. means located at the side of said fulcrum opposite said one side thereof for pivotally securing the end of said clamping lever opposite said handle portion to said first clamping jaw at the side of said first clamping jaw adjacent said second clamping jaw, h. said clamping lever being arranged to pivot between a locking position in which the portion thereof at about the apex of said U-shaped configuration presses against said second clamping jaw at said opposite side of said fulcrum to bias said gripping means of said clamping jaws towards each other to grip said cleaning element and a release position in which said clamping jaws may freely pivot permitting said gripping means to move away from each other to release said cleaning element, i. said clamping lever being arranged such that only said handle portion extends through said aperture in said first clamping jaw when said clamping lever is in said locking position and a part of said clamping lever is drawn through said aperture during pivotal movement of said clamping lever to said release position.
Claim 2
Dependent Claim
269 words
A squeegee, particularly for cleaning window panes and floors, comprising a. an exchangeable substantially strip-shaped cleaning element, b. first and second clamping jaws, c. means for pivotally securing said clamping jaws together for movement about a fulcrum, d. gripping means on each of said first and second clamping jaws on one side of said fulcrum for gripping opposite sides of said cleaning element, e. an aperture in said first clamping jaw, f. a clamping lever having a generally U-shaped configuration and including a handle portion at one end thereof, g. means located at the side of said fulcrum opposite said one side thereof for pivotally securing the end of said clamping lever opposite said handle portion to said first clamping jaw at the side of said first clamping jaw adjacent said second clamping jaw, h. said clamping lever being arranged to pivot between a locking position in which the portion thereof at about the apex of said U-shaped configuration presses against said second clamping jaw at said opposite side of said fulcrum to bias said gripping means of said clamping jaws towards each other to grip said cleaning element and a release position in which said clamping jaws may freely pivot permitting said gripping means to move away from each other to release said cleaning element, i. said clamping lever being arranged such that only said handle portion extends through said aperture in said first clamping jaw when said clamping lever is in said locking position and a part of said clamping lever is drawn through said aperture during pivotal movement of said clamping lever to said release position.
Claim 3
Dependent Claim
15 words
A squeegee as defined in claim 1 wherein said clamping lever is a bellcrank lever.
Claim 4
Dependent Claim
66 words
A squeegee as defined in claim 1 wherein said means for pivotally securing said clamping lever comprises a pair of spaced eyelets formed by a curled edge of said first clamping jaw and said clamping lever comprises an elongated wire member shaped such that the center portion thereof forms said handle pOrtion and the opposite ends of said wire member are pivotally secured in said eyelets.
Claim 5
Dependent Claim
63 words
A squeegee as defined in claim 1 wherein a portion of said first clamping jaw surrounding said aperture is countersunk in the direction of said second clamping jaw forming a recess in said first clamping jaw and said handle portion is arranged such that at least a portion thereof is accommodated within said recess when said clamping lever is in said locking position.
Claim 6
Dependent Claim
57 words
A squeegee as defined in claim 4 wherein said handle portion has a greater dimension than said aperture in at least one direction whereby a portion of said first clamping jaw adjacent said aperture prevents said handle portion of said clamping lever from passing through said aperture when said clamping lever is moved to said locking position.
Claim 7
Dependent Claim
26 words
A squeegee as defined in claim 5 wherein a handle for manually operating said squeegee is attached to one of said first and second clamping jaws.
Claim 8
Dependent Claim
30 words
A squeegee as defined in claim 4 wherein said means for pivotally securing said clamping jaws together includes means for adjusting the distance between said first and second clamping jaws.
