Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
A window comprising: a window frame having a left vertical leg and a right vertical leg disposed at respective left and right exterior sides of the frame, the vertical legs each having a vertical conduit formed at an interior portion thereof and a vertical slit communicating between the vertical conduit and the interior of the window frame; a window pane, slidably disposed within the frame, the window pane having left and right edges respectively projecting into the vertical slits of the left and right vertical legs; left and right sliding members, made of an elongated flexible material having a predetermined compression strength, respectively disposed in the vertical conduits of the left and right vertical legs, the sliding members being coupled to the window pane for sliding the window pane vertically within the frame; and a drive means, coupled to the left and right sliding members, for moving the sliding members in unison through their respective vertical conduits to thereby move the window pane.
Claim 2
Dependent Claim
163 words
A window comprising: a window frame having a left vertical leg and a right vertical leg disposed at respective left and right exterior sides of the frame, the vertical legs each having a vertical conduit formed at an interior portion thereof and a vertical slit communicating between the vertical conduit and the interior of the window frame; a window pane, slidably disposed within the frame, the window pane having left and right edges respectively projecting into the vertical slits of the left and right vertical legs; left and right sliding members, made of an elongated flexible material having a predetermined compression strength, respectively disposed in the vertical conduits of the left and right vertical legs, the sliding members being coupled to the window pane for sliding the window pane vertically within the frame; and a drive means, coupled to the left and right sliding members, for moving the sliding members in unison through their respective vertical conduits to thereby move the window pane.
Claim 3
Dependent Claim
45 words
The window of claim 1 wherein the sliding members are slotted tapes, and the window further comprises left and right couplers having projecting fingers that are insertable into the slots of the tapes, the left and right couplers connecting the tapes to the window pane.
Claim 4
Dependent Claim
18 words
The window of claim 2 wherein the slotted tapes are composed of a low friction, semi-rigid organic plastic.
Claim 5
Dependent Claim
24 words
The window of claim 3 wherein the tapes are composed of a plastic selected from the group consisting of a polyamide and a polyurethane.
Claim 6
Dependent Claim
83 words
The window of claim 1 wherein each vertical leg is further provided with a vertical gasket chamber that is accessible through the vertical slit, the left and right edges of the window pane extend into the gasket chambers of the respective left and right vertical legs, and each vertical leg is further provided with a gasket means within its respective gasket chamber for sealing spaces between the left and right edges of the window pane and their respective left and right vertical legs.
