Abstract
Abstract A window wiper assembly, especially suitable for cleaning the tailgate window of a station wagon, is mounted inside the tailgate with a resilient rubber wiper element normally retracted from the window. As the window is raised toward its closed position, the wiper element may be distended by fluid pressure to press the wiper against the window. Simultaneously, the fluid is manifolded to sprays which wet the window while it is being wiped by the wiper element.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
A window cleaning unit for a window movable into and out of a window well, comprising: a single elongated inflatable member, a squeegee carried on said inflatable member, a fluid dispensing passageway extending longitudinally through said inflatable member, said inflatable member having a plurality of longitudinally spaced spray apertures along the length thereof communicating directly with said passageway, a retainer supporting said inflatable member for projecting outwardly said squeegee upon inflation of said passageway in said inflatable member, and pressurizing means connected to said passageway operative to inflate said inflatable member to project the squeegee from noncontacting engagement into contacting engagement with the window surface to be wetted and cleaned.
Claim 2
Dependent Claim
110 words
A window cleaning unit for a window movable into and out of a window well, comprising: a single elongated inflatable member, a squeegee carried on said inflatable member, a fluid dispensing passageway extending longitudinally through said inflatable member, said inflatable member having a plurality of longitudinally spaced spray apertures along the length thereof communicating directly with said passageway, a retainer supporting said inflatable member for projecting outwardly said squeegee upon inflation of said passageway in said inflatable member, and pressurizing means connected to said passageway operative to inflate said inflatable member to project the squeegee from noncontacting engagement into contacting engagement with the window surface to be wetted and cleaned.
Claim 3
Dependent Claim
148 words
A window cleaning unit for a window movable into and out of a window well comprising: an elongated inflatable member, a squeegee carried on said inflatable member, said inflatable member having a fluid dispensing passageway therein entending throughout the length thereof, a plurality of spray apertures in said inflatable member communicating directly with said passageway with atmosphere, a retainer supporting said inflatable member in adjacent relationship to a window surface to be cleaned, a reservoir of washer solvent connected to said passageway in said inflatable member, and a pump for pressurizing the washer solvent to pump washer solvent to said passageway to inflate said inflatable member to project said squeegee from noncontacting engagement into contacting engagement with the window surface and for the dispersal of solvent through said spray apertures for wetting said window and wiping the window upon movement past said spray apertures and said squeegee respectively.
Claim 4
Dependent Claim
148 words
A window cleaning unit for a window movable into and out of a window well comprising: an elongated inflatable member, a squeegee carried on said inflatable member, said inflatable member having a fluid dispensing passageway therein entending throughout the length thereof, a plurality of spray apertures in said inflatable member communicating directly with said passageway with atmosphere, a retainer supporting said inflatable member in adjacent relationship to a window surface to be cleaned, a reservoir of washer solvent connected to said passageway in said inflatable member, and a pump for pressurizing the washer solvent to pump washer solvent to said passageway to inflate said inflatable member to project said squeegee from noncontacting engagement into contacting engagement with the window surface and for the dispersal of solvent through said spray apertures for wetting said window and wiping the window upon movement past said spray apertures and said squeegee respectively.
Claim 5
Dependent Claim
165 words
A window wiper assembly comprising a tubular flexible resilient member; said resilient member having a pair of flat sides, a rigid retainer for supporting said tubular member; said rigid retainer having side flanges directed outwardly toward each other to define a channel for holding said resilient member and limiting the outward movement of said resilient member upon distension; said resilient member having a window-engaging wiping bead along one side of said resilient member; means for mounting said retainer in fixed relation to an associated window; said flat resilient member having a single passageway extending therethrough; a plurality of spray apertures in said inflatable member located to one side of said bead and within said side flanges communicating said passageway with atmosphere; means for communicating a fluid medium with said passageway for distending said body and projecting said wiping bead from noncontacting engagement into contacting engagement with an associated window while simultaneously directing a portion of such fluid medium against such associated window through said apertures.
Claim 6
Dependent Claim
165 words
A window wiper assembly comprising a tubular flexible resilient member; said resilient member having a pair of flat sides, a rigid retainer for supporting said tubular member; said rigid retainer having side flanges directed outwardly toward each other to define a channel for holding said resilient member and limiting the outward movement of said resilient member upon distension; said resilient member having a window-engaging wiping bead along one side of said resilient member; means for mounting said retainer in fixed relation to an associated window; said flat resilient member having a single passageway extending therethrough; a plurality of spray apertures in said inflatable member located to one side of said bead and within said side flanges communicating said passageway with atmosphere; means for communicating a fluid medium with said passageway for distending said body and projecting said wiping bead from noncontacting engagement into contacting engagement with an associated window while simultaneously directing a portion of such fluid medium against such associated window through said apertures.
