Abstract
Abstract A squeegee for mounting on the back of a operator's hand, comprising a base portion; a device for attaching the base portion to a operator's hand, such device preferably a strap, a upwardly projecting portion attached to said base at its lower end, the upwardly projecting portion being flexible and thin enough for good wiping qualities. The outwardly projecting portion being thick enough to avoid a tendency to ride over the top of water on a smooth surface to be squeegeed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
346 words
A squeegee for mounting on the back of an operator's hand comprising a base elongated from left to right and having left and right ends and front and rear sides, said base having an undersurface having a forward side and a rearward side, the lowermost portions of the outer edges of which lie substantially in a first plane, an upwardly projecting protrusion attached to said base and also elongated from left to right, a hand-encircling means for extending around an operator's hand, attaching means attaching said hand-encircling means to said base, said protrusion having a forward side and a rearward side together defining a pair of elongated sides extending along the elongation of said protrusion, said protrusion having an upper end having a wiping edge on at least one side of its said pair of sides, said wiping edge having at least one elongated portion extending from left to right, said pair of sides extending along the elongation of said protrusion and transversely to said first plane, there being for reference a second plane parallel to said first plane and extending through said wiping edge, said forward and rearward sides of said protrusion being spaced to provide a specific flexibility such that when pressure is placed on said protrusion so that it bends to that one of its pair of sides which is opposite from said one side on which said wiping edge is disposed then the attack angle which said one side of said protrusion makes with respect to a second plane parallel to said first plane will be substantially 20 degrees to 40 degrees when said bending is caused by a pressing force from an operator's wrist which is at substantially the maximum which will not dislodge from an operator's face a pair of over-the-ear bow type of spectacles on which is the lens being wiped, such spectacles having a capability of gripping the operator's head with an average gripping resistance to the dislodging of the spectacles by such a wiping force when such force is applied during a horizontal motion of the squeegee.
Claim 2
Dependent Claim
346 words
A squeegee for mounting on the back of an operator's hand comprising a base elongated from left to right and having left and right ends and front and rear sides, said base having an undersurface having a forward side and a rearward side, the lowermost portions of the outer edges of which lie substantially in a first plane, an upwardly projecting protrusion attached to said base and also elongated from left to right, a hand-encircling means for extending around an operator's hand, attaching means attaching said hand-encircling means to said base, said protrusion having a forward side and a rearward side together defining a pair of elongated sides extending along the elongation of said protrusion, said protrusion having an upper end having a wiping edge on at least one side of its said pair of sides, said wiping edge having at least one elongated portion extending from left to right, said pair of sides extending along the elongation of said protrusion and transversely to said first plane, there being for reference a second plane parallel to said first plane and extending through said wiping edge, said forward and rearward sides of said protrusion being spaced to provide a specific flexibility such that when pressure is placed on said protrusion so that it bends to that one of its pair of sides which is opposite from said one side on which said wiping edge is disposed then the attack angle which said one side of said protrusion makes with respect to a second plane parallel to said first plane will be substantially 20 degrees to 40 degrees when said bending is caused by a pressing force from an operator's wrist which is at substantially the maximum which will not dislodge from an operator's face a pair of over-the-ear bow type of spectacles on which is the lens being wiped, such spectacles having a capability of gripping the operator's head with an average gripping resistance to the dislodging of the spectacles by such a wiping force when such force is applied during a horizontal motion of the squeegee.
Claim 3
Dependent Claim
13 words
The squeegee of claim 1 herein said attack angle is substantially 30 degrees.
Claim 4
Dependent Claim
103 words
The squeegee of claim 1 wherein the distance between said forward and rearward sides of said protrusion at the upper end of said protrusion defining a first distance, said first distance being between 1/32nd and 3/32nds inch, said forward and rearward sides of said protrusion being spaced such that said average thickness of said protrusion from forward to rearward is such as would occur if said protrusion is approximately 1/2 inch in height and if its forward and rearward sides were inclinedly disposed diverging from each other as their downward sides are approached, such diverging being at an angle of substantially 10 degrees.
Claim 5
Dependent Claim
102 words
The squeegee of claim 1 wherein said attachment means comprises a strap having two ends, a clasp attached to one end portion of said strap, said clasp being capable of releasable adjustable attachment at various positions on the other end portion of said strap, said positions varying in spacing with respect to each other by infinite amounts, said strap being formed of elastic material which has an amount of elasticity which will hold firmly when disposed closely against the operator's wrist but which will not cut off circulation at the operator's wrist to an extent that the respective hand would become numb.
Claim 6
Dependent Claim
37 words
The squeegee of claim 1 wherein the nose clearance distance from the underside of said base to said wiping edge being at least 27/32nds of an inch so that the operator's nose does not interfere with wiping.
Claim 7
Dependent Claim
17 words
The squeegee of claim 5 wherein said clearance distance is substantially 1 and 3/32nds of an inch.
