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 brake arrangement for a covering for an architectural opening, the arrangement comprising:
a hollow rail;
a rod extending within said hollow rail and being rotatable about an axis of rotation;
a brake provided for movement into and out of engagement with said rod to prevent or allow rotation of said rod about said axis of rotation, respectively;
a button assembly provided in operative association with said hollow rail, said button assembly comprising:
a button housing coupled to said hollow rail;
an actuator button supported by said button housing for movement relative to said button housing; and
a pusher rod provided in operative association with said actuator button, said pusher rod extending between a first end proximal to said actuator button and a second end distal to said actuator button;

wherein said second end of said pusher rod comprises a free end of said pusher rod configured to abut against a portion of said brake to disengage said brake from said rod with actuation of said actuator button.

2. The brake arrangement of claim 1 , wherein:
said pusher rod extends in a lengthwise direction between said first end of said pusher rod and said second end of said pusher rod; and
said pusher rod is configured to engage said portion of said brake in the lengthwise direction.

3. The brake arrangement of claim 2 , wherein:
said portion of said brake comprises a movable portion of said brake; and
said pusher rod is configured to actuate said movable portion of said brake in the lengthwise direction to disengage said brake from said rod with actuation of said actuator button.

4. The brake arrangement of claim 1 , wherein:
said first end of said pusher rod comprises a free end of said pusher rod; and
a portion of said actuator button is configured to press against said first end of said pusher rod with actuation of said actuator button relative to said button housing.

5. The brake arrangement of claim 1 , wherein said button housing comprises a handle configured to be grasped by a user of the brake arrangement when moving the covering relative to the architectural opening.

6. The brake arrangement of claim 1 , wherein said actuator button is supported along a top side of said button housing such that said actuator button is configured to be actuated downwardly relative to said button housing.

7. The brake arrangement of claim 6 , wherein:
said first end of said pusher rod defines a ramped profile; and
downward movement of said actuator button relative to said button housing moves a portion of said actuator button against said ramped profile of said first end of said pusher rod to move said pusher rod towards said portion of said brake.

8. The brake arrangement of claim 1 , wherein:
said button housing is coupled to said hollow rail by a fastener; and
said button housing conceals the fastener from view from an exterior front face of said hollow rail along which said button housing extends.

9. The brake arrangement of claim 1 , wherein said actuator button is supported by said button housing for pivotable movement relative to said button housing.

10. The brake arrangement of claim 9 , wherein said actuator button is configured to move along an arcuate path relative to said button housing towards said hollow rail with actuation of said actuator button.

11. The brake arrangement of claim 1 , wherein:
said hollow rail includes a wall defining an exterior face along which said button housing is coupled to said hollow rail; and
said pusher rod extends through said wall such that said first end of said pusher rod is located along an exterior of said hollow rail and said second end of said pusher rod is located within an interior of said hollow rail.

12. A brake arrangement for a covering for an architectural opening, the arrangement comprising:
a hollow rail defining an exterior front face;
a rod extending within said hollow rail and being rotatable about an axis of rotation;
a brake provided for movement into and out of engagement with said rod to prevent or allow rotation of said rod about said axis of rotation, respectively; and
a button assembly provided in operative association with said hollow rail, said button assembly comprising:
a button housing coupled to said hollow rail along said exterior front face of said hollow rail; and
an actuator button supported by said button housing for pivotable movement relative to said button housing;

wherein, when said actuator button is moved relative to said button housing, said brake is actuated relative to said rod to disengage said brake from said rod.

13. The brake arrangement of claim 12 , wherein said actuator button is configured to move along an arcuate path relative to said button housing towards said hollow rail with actuation of said actuator button.

14. The brake arrangement of claim 12 , wherein said button housing comprises a handle configured to be grasped by a user of the brake arrangement when moving the covering relative to the architectural opening.

15. The brake arrangement of claim 12 , wherein said actuator button is supported along a top side of said button housing such that said actuator button configured to be pivoted downwardly relative to said button housing.

16. The brake arrangement of claim 12 , further comprising a pusher rod provided in operative association with said actuator button and extending at least partially within said hollow rail, said pusher rod being configured to actuate said brake relative to said rod with movement of said actuator button relative to said button housing.

17. The brake arrangement of claim 16 , wherein:
said pusher rod extends between a first end proximal to said actuator button and a second end distal to said actuator button; and
said second end of said pusher rod comprises a free end of said pusher rod configured to abut against a portion of said brake to disengage said brake from said rod with movement of said actuator button relative to said button housing.

18. The brake arrangement of claim 17 , wherein:
said first end of said pusher rod defines a ramped profile; and
pivotable movement of said actuator button relative to said button housing moves a portion of said actuator button against said ramped profile of said first end of said pusher rod to move said pusher rod towards said portion of said brake.

19. The brake arrangement of claim 17 , wherein:
said first end of said pusher rod comprises another free end of said pusher rod; and
a portion of said actuator button is configured to press against said first end of said pusher rod with actuation of said actuator button relative to said button housing.

20. The brake arrangement of claim 17 , wherein:
said hollow rail includes a wall defining said exterior front face of said hollow rail; and
said pusher rod extends through said wall such that said first end of said pusher rod is located along an exterior of said hollow rail and said second end of said pusher rod is located within an interior of said hollow rail.
