Abstract
Abstract A squeegee assembly having a tapered, flexible blade edge that will not develop a wary surface through use. The blade edge is formed on a flexible blade member, which blade member is disposed about and attached to another less flexible blade member. The flexible blade members may be symmetrically formed about a longitudinal axis, and the flexible blade member may include a blade edge formed on either side thereof. A blade support member having a shaped notch for receiving the flexible blade member provides longitudinal support therefor. The blade support member and flexible blade members are held and supported by a handle and trigger assembly having trigger actuated jaws.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
75 words
A squeegee assembly comprising (a) blade means for providing a blade edge that is not significantly susceptible to developing a wavy surface, comprising: (i) a first substantially flexible blade member having opposite substantially parallel longitudinal tapered edges; and (ii) a second flexible blade member substantially disposed symmetrically longitudinally around and permanently attached to said first blade member and having opposite tapered blade edges formed longitudinally thereon; and (b) handle means for supporting said blade means.
Claim 2
Dependent Claim
75 words
A squeegee assembly comprising (a) blade means for providing a blade edge that is not significantly susceptible to developing a wavy surface, comprising: (i) a first substantially flexible blade member having opposite substantially parallel longitudinal tapered edges; and (ii) a second flexible blade member substantially disposed symmetrically longitudinally around and permanently attached to said first blade member and having opposite tapered blade edges formed longitudinally thereon; and (b) handle means for supporting said blade means.
Claim 3
Dependent Claim
105 words
In a squeegee assembly, an improved dual durometer blade that is not significantly susceptible to developing a wavy surface, comprising: (a) a plastic extruded core member; and (b) an exterior extruded member serving as a blade member, wherein: (i) said extruded core member includes opposite substantially parallel longitudinal tapered edges; and (ii) said exterior extruded member is substantially disposed symmetrically longitudinally around about and is permanently attached to said extruded core member, and said exterior extruded member is comprised of material more flexible than the material comprising said core member, and said exterior extruded member includes at least one tapered blade edge formed longitudinally thereon.
Claim 4
Dependent Claim
105 words
In a squeegee assembly, an improved dual durometer blade that is not significantly susceptible to developing a wavy surface, comprising: (a) a plastic extruded core member; and (b) an exterior extruded member serving as a blade member, wherein: (i) said extruded core member includes opposite substantially parallel longitudinal tapered edges; and (ii) said exterior extruded member is substantially disposed symmetrically longitudinally around about and is permanently attached to said extruded core member, and said exterior extruded member is comprised of material more flexible than the material comprising said core member, and said exterior extruded member includes at least one tapered blade edge formed longitudinally thereon.
