Abstract

An arrangement for mounting an actuator button to a rail wherein the fastener for securing the button housing to the rail is hidden from view of the user.

First claim

What is claimed is:

1. A brake arrangement for a covering for an architectural opening, the arrangement comprising:
a hollow rail defining an exterior front face and an interior;
a rod extending within said interior of said hollow rail and being rotatable about an axis of rotation;
a brake provided in operative association with said rod, said brake configured to be selectively disengaged from said rod to allow said rod to rotate about said axis of rotation;
an actuator button supported relative to said hollow rail along said exterior front face of said hollow rail, said actuator button being configured for movement relative to said exterior front face of said hollow rail in an actuation direction extending toward and away from said axis of rotation of said rod;
a pusher rod extending within said hollow rail and provided in operative association with said actuator button, said pusher rod being configured for movement relative to said brake;
wherein, when said actuator button is moved in the actuation direction, said pusher rod actuates said brake relative to said rod to disengage said brake from said rod.

2. The brake arrangement of claim 1 , wherein said pusher rod is configured for movement with said actuator button in the actuation direction when said actuator button is moved in the actuation direction.

3. The brake arrangement of claim 1 , wherein said pusher rod is formed integrally with or rigidly coupled to said actuator button.

4. The brake arrangement of claim 1 , wherein said pusher rod extends from a back side of said actuator button.

5. The brake arrangement of claim 1 , wherein the actuation direction extends perpendicular to said axis of rotation of said rod.

6. The brake arrangement of claim 1 , wherein:
said exterior front face of said hollow rail corresponds to a substantially planar face of said hollow rail; and
said substantially planar face extends perpendicular to the actuation direction of said actuator button.

7. The brake arrangement of claim 1 , wherein a movable portion of said brake is configured to be moved relative to said rod to selectively disengage said brake from said rod.

8. The brake arrangement of claim 7 , wherein:
when said pusher rod is moved in the actuation direction with said actuator button, said pusher rod contacts said movable portion of said brake; and
said pusher rod is configured to actuate said movable portion of said brake in the actuation direction.

9. The brake arrangement of claim 7 , wherein:
said movable portion of said brake is biased towards a braking position at which said brake engages said rod to prevent rotation of said rod about said axis of rotation; and
when said actuator button is released following movement of said actuator button in the actuation direction, said actuator button moves away from said rod as said movable portion of said brake is biased towards said braking position.

10. The brake arrangement of claim 7 , wherein said pusher rod is configured for movement relative to said movable portion of said brake.

11. The brake arrangement of claim 1 , further comprising a button housing coupled to said hollow rail such that said button housing is positioned at least partially at said exterior front face of said hollow rail, said actuator button being received within said button housing along said exterior front face of said hollow rail.

12. The brake arrangement of claim 11 , wherein:
said button housing defines a button cavity configured to receive said actuator button; and
said actuator button is movable relative to said button housing within said button cavity along the actuation direction.

13. The brake arrangement of claim 11 , wherein said button housing is mounted to said hollow rail such that at least a portion of said button housing is recessed relative to said exterior front face of said hollow rail.

14. The brake arrangement of claim 11 , wherein:
said button housing defines a button cavity extending in the actuation direction between an open end and an opposed wall; and
said button housing is mounted to said exterior front face of said hollow rail such that said wall is positioned directly adjacent to said exterior front face.

15. The brake arrangement of claim 14 , wherein said button housing is mounted to said hollow rail via at least one fastener extending through both said wall of said housing and said exterior front face.

16. The brake arrangement of claim 11 , wherein a portion of said button housing extends through said exterior front face and is received within said interior of said hollow rail.

17. The brake arrangement of claim 16 , wherein said portion of said button housing defines a hollow shaft for supporting said pusher rod for movement in the actuation direction.

18. A brake arrangement for a covering for an architectural opening, said brake arrangement comprising:
a hollow rail defining an exterior front face and a substantially hollow interior;
a rod extending within said interior of said hollow rail and operative to cause said covering to extend or to retract;
a brake configured and arranged to prevent or allow movement of said covering; and
an actuator button formed separately from said brake and supported relative to said rail, said actuator button configured for movement relative to said rail in a direction toward and away from said rod to actuate said brake;
wherein said brake is separately supported within said rail for movement relative to said actuator button along an axial direction of said rod when installing said brake relative to said actuator button.

19. The brake arrangement of claim 18 , wherein said brake is provided for movement into and out of engagement with said rod to actuate said brake to prevent or allow movement of said covering, respectively.

20. The brake arrangement of claim 18 , wherein said brake engages said rod to prevent both rotation of said rod and extension or retraction of said covering.

21. The brake arrangement of claim 18 , wherein said actuator button is configured for movement relative to said rail in a direction perpendicular to the axial direction of said rod.

22. The brake arrangement of claim 18 , further comprising a pusher rod extending within said hollow rail, said pusher rod being configured for movement with said actuator button relative to said brake when said actuator button is moved in said direction towards said rail.

23. The brake arrangement of claim 22 , wherein:
when said pusher rod is moved in the direction towards said rail with said actuator button, said pusher rod contacts a movable portion of said brake; and
said pusher rod is configured to actuate said movable portion of said brake to cause said brake to be disengaged from said rod.

24. A brake arrangement for a covering for an architectural opening, said brake arrangement comprising:
a hollow rail defining an exterior front face and a substantially hollow interior;
a rod extending within said interior of said hollow rail and operative to cause said covering to extend or to retract;
a brake comprising an engagement portion oriented towards said rod and configured for movement into and out of engagement with said rod to actuate said brake to prevent or allow movement of said covering, respectively; and
an actuator button supported relative to said exterior front face of said rail and formed separately from said brake, said actuator button supported for movement toward and away from said brake to
