Window Shade

1 . A window shade system, comprising:

a headrail configured for mounting adjacent a window;

a rotatable roller mounted to the headrail having a first end and a second end opposite the first end; and

a support mechanism disposed between the first and second ends of the roller and having a first portion and a second portion, the first portion of the support mechanism being secured to the headrail and the second portion of the support mechanism having a bore through which the roller extends.

2 . The window shade system of claim 1 , wherein the bore has a surface that comes in movable contact with a portion of the roller.

3 . The window shade system of claim 2 , wherein the surface of the bore is coated with a friction reducing material.

4 . The window shade system of claim 3 , wherein the friction reducing material is Teflon.

5 . The window shade system of claim 1 , wherein the support mechanism is comprised of metal, plastic, or wood.

6 . The window shade system of claim 1 , wherein the first portion of the support mechanism has a hole adapted to receive a fastener.

7 . The window shade system of claim 1 , wherein the roller includes at least one channel disposed along the length of the roller.

8 . The window shade system of claim 7 , further including a first stop member which engages the walls defining the channel of the roller and is fixedly attached to the roller, wherein the first stop member is disposed on a first side of the support mechanism such that the first stop member engages the support mechanism when the roller moves in a first direction.

9 . The window shade system of claim 8 , further including a second stop which engages the walls defining the channel of the roller and is fixedly attached to the roller, wherein the second stop member is disposed on a second side of the support mechanism such the second stop member engages the support mechanism when the roller moves in a second direction, opposition the first direction.

10 . The window shade system of claim 9 , wherein engagement of the first stop member or the second stop member with the support mechanism stops movement of the roller in the first direction or the second direction, respectively.

11 . A window shade comprising:

a headrail configured for mounting adjacent a window;

a rotatable roller mounted to the headrail;

a shading material having a first end attached to the headrail, a second end opposite the first end, and a face between the first and second ends;

a cord disposed adjacent the face and secured to the roller wherein rotation of the roller causes the cord to be wound about or unwound from the roller for moving the shading material between a stowed position in which the shading material is collected adjacent the headrail and a deployed position in which at least a portion of the shading material extends away from the headrail; and

a support mechanism disposed between a first end and a second end of the roller and having a first portion and a second portion, the first portion of the support mechanism being secured to the headrail and the second portion of the support mechanism having a bore configured to receive the roller.

12 . The window shade of claim 11 , wherein the bore has a surface that comes in movable contact with a portion of the roller.

13 . The window shade of claim 12 , wherein the surface of the bore is coated with a friction-reducing material.

14 . The window shade of claim 11 , wherein the first portion of the support mechanism has at least one hole adapted to received a fastener.

15 . The window shade of claim 11 , wherein the roller includes at least one channel disposed along the length of the roller.

16 . The window shade of claim 15 , further including at least one stop member that engages the walls defining the channel of the roller and is fixedly attached to the roller.

17 . The window shade of claim 16 , wherein the stop member is disposed adjacent the support mechanism and restricts lateral movement of the roller in a first direction.

18 . The window shade of claim 17 , wherein the stop member is configured to receive the cord and secures the cord to the roller.

19 . The window shade of claim 11 , further including first, second, and third spaced cord guides secured to and extending outwardly from the face, wherein the first cord guide is disposed at a first location, the second cord guide is disposed at a second location farther away from the headrail than the first location, and the third cord guide is disposed at a third location father away from the headrail than the first and second locations, wherein the cord is secured to the shading material at a further location farther away from the headrail than the third location and wherein each cord guide surrounds the cord.

20 . The window shade of claim 19 , further including a shroud defining an internal passage through which the cord extends, wherein the shroud is configured to extend longitudinally as the shade material is moved toward the deployed position and the shroud is adapted to collages longitudinally as the shade material is moved toward the stowed position wherein the shroud is unsecured to the shading material at all location between cord guides.

21 . The window shade of claim 11 , further including a stop bracket disposed adjacent the face having a first potion attached to the headrail and a second portion containing a bore, wherein the cord extends from the roller through the bore and is secured to the shading material.
