Abstract

A handle is releasably secured to a rail wall by means of fasteners extending from inside the rail. An actuator shaft pushes against a contact plate to move a movable braking member to stop the rotation of a rod inside the rail.

First claim

What is claimed is:

1. A handle arrangement for a covering for an architectural opening, said handle arrangement comprising:
a rail including a front wall, a rear wall, and a connecting wall extending between said front and rear walls, said rear wall defining a free rear edge; and
a handle supported on said front wall of said rail, said handle including a boss defining an opening accessible within an interior of said rail, said opening being defined at least partially by a guide surface and a wall spaced apart from said guide surface;
wherein said guide surface defines a fastener axis that clears the free rear edge of said rear wall of said rail when said handle is supported on said rail such that a fastener is configured to be inserted within said opening along said fastener axis from said interior of said rail.

2. The handle arrangement of claim 1 , wherein:
said handle includes a front surface and a rear surface; and
said rear surface abuts said front wall of said rail when said handle is supported on said rail.

3. The handle arrangement of claim 1 , wherein:
said wall defines a slotted yielding surface;
said fastener axis is located a distance from said slotted yielding surface at a location adjacent to said front wall of said rail; and
said distance tapers down as said slotted yielding surface extends away from said front wall of said rail.

4. The handle arrangement of claim 1 , wherein:
said fastener extends within said opening along said fastener axis; and
said fastener engages said wall to retain said handle relative to said rail.

5. The handle arrangement of claim 1 , wherein said fastener axis is oriented at a nonzero angle relative to a horizontal plane.

6. The handle arrangement of claim 1 , wherein:
said opening is aligned with a fastener opening defined through said front wall of said rail; and
said fastener opening is spaced apart vertically from the free rear edge of said rear wall of said rail.

7. The handle arrangement of claim 1 , wherein:
said fastener axis clears the free rear edge of said rear wall of said rail when said rail is in a first orientation;
said boss defines a second opening;
said second opening is defined at least partially by a second guide surface and a second wall spaced apart from said second guide surface; and
said second guide surface defines a second fastener axis that clears the free rear edge of said rear wall of said rail when said rail is positioned in a second orientation that is inverted relative to said first orientation.

8. The handle arrangement of claim 7 , wherein:
said second wall defines a second slotted yielding surface;
said second fastener axis is located a distance from said second slotted yielding surface at a location adjacent to said front wall of said rail; and
said distance tapers down as said second slotted yielding surface extends away from said front wall of said rail.

9. The handle arrangement of claim 1 , wherein said handle includes an actuator shaft extending through said front wall of said rail.

10. The handle arrangement of claim 9 , wherein said actuator shaft is configured to actuate a brake positioned within said rail.

11. The handle arrangement of claim 9 , wherein:
said actuator shaft is slidably received within a channel defined by said handle; and
said channel extends through a rail opening defined through said front wall of said rail.

12. The handle arrangement of claim 9 , wherein:
said handle further comprises a button movable relative to said rail; and
said button is configured to contact said actuator shaft to linearly actuate said actuator shaft relative to said rail.

13. A handle arrangement for a covering for an architectural opening, said handle arrangement comprising:
a rail including a front wall, a rear wall, and a connecting wall extending between said front and rear walls, said rail defining an interior cavity accessible from an exterior of said rail via a rail opening extending between said front and rear walls;
a handle supported on said front wall of said e rail, said handle including a boss defining an opening, said opening being defined at least partially by a guide surface and a wall spaced apart from said guide surface, said guide surface defining a fastener axis; and
a fastener extending along said fastener axis from said interior cavity through said front wall and into said opening to couple said handle to said rail.

14. The handle arrangement of claim 13 , wherein:
said wall defines a slotted yielding surface;
said fastener axis is located a distance from said slotted yielding surface at a location adjacent to said front wall of said rail; and
said distance tapers down as said slotted yielding surface extends away from said front wall of said rail.

15. The handle arrangement of claim 13 , wherein:
said rear wall of said rail defines a free rear edge; and
said fastener axis is oriented at a non-zero angle relative to a horizontal plane such that said fastener axis clears the free rear edge of said rear wall of said rail when said handle is supported on said rail.

16. The handle arrangement of claim 13 , wherein said handle includes an actuator shaft actuatable relative to a handle housing of said handle.

17. The handle arrangement of claim 16 , wherein said actuator shaft is configured to extend through said front wall of said rail when said handle is supported on said rail.

18. The handle arrangement of claim 16 , wherein said actuator shaft is slidably received within a channel defined by said handle housing.

19. The handle arrangement of claim 18 , wherein:
said handle further comprises a button movable relative to said handle housing; and
said button is configured to contact said actuator shaft to linearly actuate said actuator shaft within said channel.

20. A handle arrangement for a covering for an architectural opening, said handle arrangement comprising:
a rail including a front wall, a rear wall, and a connecting wall extending between said front and rear walls, said rail defining an interior cavity, said front wall of said rail defining a fastener opening that extends from a front side of said rail through said front wall to said interior cavity; and
a handle supported on the rail, said handle including a boss defining an opening extending along a fastener axis;
wherein:
said opening defined by said boss of said handle is aligned with said fastener opening defined through said front wall of said rail along said fastener axis; and
said fastener opening and said opening of said boss are configured to receive a fastener inserted along said fastener axis from said interior cavity of said rail.

21. The handle arrangement of claim 20 , wherein said handle is supported on said front wall of said rail.
