Abstract
In a roller shade for an opening such as a rear windshield of an automobile, when the shade is full closed, the pull rod is intentionally bent so as to fully conform to the peripheral edge of the opening. The bending of the pull rod can be achieved either by an axial force which may be produced by gradually reducing the distance between a pair of guide members extending on either lateral side of the opening as the pull rod moves up or by a lateral force which may be produced by placing a slope on which the pull rod rides over as it reaches its final position for fully covering the opening. By controlling the bent shape of the pull rod in a suitable manner, it is possible to entirely cover the opening without leaving any uncovered gap.
Claims9
A roller shade for selectively covering a designated area, comprising:
- a retractor mounted on a first side of said area that is to be covered;
- a screen sheet retracted in said retractor and being connected to said retractor at one end thereof;
- a pull rod attached to the other end of said screen sheet and moveable between a first position adjacent said retractor and a second position adjacent a second side of said designated area opposing said first side;
- guide means for guiding movement of said pull rod between said first position and said second position;
- drive means for actuating said pull rod between said first position and said second position;
- and
- bending means for bending said pull rod at said second position so as to make said pull rod conform to said second side of said area.
