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. An arrangement for mounting an actuator button onto a rail of a window covering, comprising:
a hollow rail defining an exterior face;
a window covering coupled to said hollow rail;
a button housing secured to said exterior face of said hollow rail by a fastener such that said button housing is located on an exterior of said hollow rail, said button housing defining a button cavity extending from a front side of said button housing to a wall of said button housing positioned adjacent to said exterior face, said fastener extending through said wall of said button housing; and
an actuator button received within said button cavity of said button housing for movement relative to said wall, said actuator button being accessible from said front side of said button housing and concealing said fastener from view from said front side of said button cavity.

2. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 1 , wherein said fastener secures said button housing to said hollow rail by extending through said button housing and into a housing adapter and by sandwiching said hollow rail between said wall of said button housing and said housing adapter.

3. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 1 , wherein;
said button housing defines at least two parallel slots; and
said actuator button has at least two projections received respectively in said two parallel slots.

4. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 3 , wherein:
said button housing defines a forward frame along said front side of said button housing at or adjacent to which each of said parallel slots terminates; and
each of said projections has a ramped rear surface which allows said actuator button to be pushed rearwardly relative to said forward frame for assembly of said actuator button within said button cavity, with said ramped rear surfaces abutting said forward frame and causing said projections to flex until said projections pass through said forward frame and into said parallel slots, thereby securing said actuator button within said button cavity.

5. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 1 , wherein said actuator button includes a pusher rod that is directed into an interior of said hollow rail when said actuator button is received within said button cavity of said button housing.

6. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 5 , further comprising a brake mounted inside said hollow rail;
wherein pushing said actuator button inwardly towards said wall causes said pusher rod to release said brake.

7. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 6 , wherein:
said brake is operatively connected to a lift rod, which is operatively connected to a plurality of lift spools; and
said plurality of lift spools are operatively connected to lift cords, which are operatively connected to said window covering.

8. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 5 , further comprising a hollow shaft positioned relative to said button housing;
wherein said hollow shaft is configured to receive said pusher rod to guide movement of said pusher rod relative to said hollow rail.

9. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 8 , wherein said hollow shaft extends through said exterior face of said hollow rail and is received within said button cavity.

10. An arrangement for mounting an actuator button onto a rail of a window covering, comprising:
a hollow rail defining an exterior face;
a window covering coupled to said hollow rail;
a button housing secured to said exterior face of said hollow rail by a fastener and extending outwardly from said hollow rail to a forward side of said button housing, said button housing defining at least two parallel slots terminating at a forward frame of said button housing disposed at said forward side of said button housing; and
an actuator button provided in operative association with said button housing for movement relative to said button housing, said actuator button being accessible from said front side of said button housing and concealing said fastener from view from said front side of said button housing;
wherein:
said actuator button has at least two projections received respectively in said two parallel slots of said button housing; and
each of said projections has a ramped rear surface which allows said actuator button to be pushed rearwardly relative to said forward frame for assembly of said actuator button relative to said button housing, with said ramped rear surfaces abutting said forward frame and causing said projections to flex until said projections pass through said forward frame and into said parallel slots, thereby securing said actuator button relative to said button housing.

11. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 10 , wherein said actuator button includes a pusher rod that is directed into an interior of said hollow rail when said actuator button is assembled relative to said button housing.

12. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 11 , further comprising a hollow shaft positioned relative to said button housing;
wherein said hollow shaft is configured to receive said pusher rod to guide movement of said pusher rod relative to said hollow rail.

13. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 12 , wherein said hollow shaft extends through said exterior face of said hollow rail and is received within said button housing.

14. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 10 , further comprising a brake mounted inside said hollow rail;
wherein pushing said actuator button inwardly relative to said hollow rail causes said pusher rod to release said brake.

15. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 14 , wherein:
said brake is operatively connected to a lift rod, which is operatively connected to a plurality of lift spools; and
said plurality of lift spools are operatively connected to lift cords, which are operatively connected to said window covering.

16. The arrangement for mounting an actuator button onto a rail of a window covering as recited in claim 10 , wherein said fastener secures said button housing to said hollow rail by extending through said housing and into a housing adapter and by sandwiching said hollow rail between said housing and said housing adapter.

17. An arrangement tier mounting an actuator button onto a rail of a window covering, comprising:
a hollow rail defining an exterior face;
a window covering coupled to said hollow rail;
a button housing secured to said exterior face of said hollow rail by a fastener and extending outwardly from said hollow rail to a forward side of said button housing;
an actuator button provided in operative association with said button housing for movement relative to said button housing, said actuator button being accessible from said front side of said button housing and concealing said fastener from view from said front side of said
