Abstract
Abstract A practical and safe shower shade that is retractable for storage and extensible for use, and embodied in a housing that is anchored by opposed plates to the opposite stiles of a stall or the like, the retractile force and the extensibility being adjustable upon installation, and manual control being provided for release of the shade for its retraction into the housing for storage. The shade per se, the supporting roller and the housing elements are formed to a dimension (nominal or specified) to accomodate the stall opening, while the mounting plates, retraction means and extension limiting means remain the same for all installations.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
94 words
In combination with a retractile and extensible shade of flexible sheet reeled from a roller journaled upon spaced mounting plates, a revolvably adjustable retraction means fixedly anchored to the mounting plate at one end of the roller and biasing the roller to reel the sheet thereon, a revolvably adjustable extension limiting means fixedly anchored to the mounting plate at the other end of the roller and having a stop engageable with an element positioned by turning of the roller, and a latch means releasably engaging the said element and holding it against said stop.
Claim 2
Dependent Claim
94 words
In combination with a retractile and extensible shade of flexible sheet reeled from a roller journaled upon spaced mounting plates, a revolvably adjustable retraction means fixedly anchored to the mounting plate at one end of the roller and biasing the roller to reel the sheet thereon, a revolvably adjustable extension limiting means fixedly anchored to the mounting plate at the other end of the roller and having a stop engageable with an element positioned by turning of the roller, and a latch means releasably engaging the said element and holding it against said stop.
Claim 3
Dependent Claim
68 words
The extensible shade in combination as set forth in claim 1 wherein the extension limiting means comprises a revolvably adjustably feed screw fixedly anchored to its mounting plate and projecting into the roller, and wherein the said element releasably engaged by the latch means is a nut threaded onto the feed screw and slideable in and turned by the roller to advance to and retract from said stop.
Claim 4
Dependent Claim
77 words
The extensible shade in combination as set forth in claim 1 wherein the extension limiting means comprises a revolvably adjustable feed screw fixedly anchored to its mounting plate and projecting into the roller, means rotatably journaling the roller about said feed screw, and wherein the said element releasably engaged by the latch means is a nut threaded onto the feed screw and slideable in and turned by the roller to advance to and retract from said stop.
Claim 5
Dependent Claim
86 words
The extensible shade in combination as set forth in claim 1 wherein the extension limiting means comprises a revolvably adjustable feed screw fixedly anchored to its mounting plate and projecting into the roller, means comprising a drive tube fixed within the roller with a disc journaled on the feed screw, and wherein the said element releasably engaged by the latch means is a nut threaded onto the feed screw and slideable in and turned by the drive tube to advance to and retract from said stop.
Claim 6
Dependent Claim
127 words
In combination with a retractile and extensible shade of flexible sheet reeled from a roller journaled upon spaced mounting plates, a revolvably adjustable retraction means fixedly anchored to the mounting plate at one end of the roller and biasing the roller to reel the sheet thereon, a revolvably adjustable extension limiting means comprised of a feed screw fixedly anchored to its mounting plate and projecting through a hub carrying a stop at the end of the roller, a traveling element in the form of a nut threaded onto the feed screw and engageable with the said stop and slideable in and turned by the roller to advance to and retract from said stop, and latch means releasably engaging the said element and holding it against said stop.
Claim 7
Dependent Claim
127 words
In combination with a retractile and extensible shade of flexible sheet reeled from a roller journaled upon spaced mounting plates, a revolvably adjustable retraction means fixedly anchored to the mounting plate at one end of the roller and biasing the roller to reel the sheet thereon, a revolvably adjustable extension limiting means comprised of a feed screw fixedly anchored to its mounting plate and projecting through a hub carrying a stop at the end of the roller, a traveling element in the form of a nut threaded onto the feed screw and engageable with the said stop and slideable in and turned by the roller to advance to and retract from said stop, and latch means releasably engaging the said element and holding it against said stop.
