EXTENSIBLE HEADRAIL CAP ASSEMBLY FOR A WINDOW COVERING
An apparatus for installing a window covering is disclosed. In one embodiment, such an apparatus includes a stationary portion for attachment to an end of a headrail of a window covering, and a moveable portion to contact an inside of a window casing. A threaded member is provided that, when rotated, translates the moveable portion relative to the stationary portion. A manual actuator is provided to rotate the threaded member. In certain embodiments, the actuator is a thumb wheel configured to rotate the threaded member. In other embodiments, the actuator is a lever arm, such as a ratcheting lever arm, configured to rotate the threaded member. A corresponding method is also disclosed and claimed herein.
1 . An apparatus for installing a window covering comprising:
a stationary portion for attachment to an end of a headrail of the window covering;
a moveable portion to contact an inside of a window casing;
a threaded member to, upon rotation, translate the moveable portion relative to the stationary portion; and
an actuator to rotate the threaded member, wherein when the actuator is rotated the threaded member pushes against the stationary portion to create a compression fit between the headrail and the window casing.
2 . The apparatus of claim 1 , wherein the actuator is a thumb wheel.
3 . The apparatus of claim 2 , wherein the thumb wheel includes an aperture on a circumference thereof for insertion of a tool.
4 . The apparatus of claim 1 , wherein the actuator is a lever arm.
5 . The apparatus of claim 4 , wherein the lever arm is a ratcheting lever arm.
6 . The apparatus of claim 5 , wherein the ratcheting lever arm includes functionality to enable reversal of a ratcheting mechanism.
7 . The apparatus of claim 1 , wherein the moveable portion includes a mounting bracket to enable mounting of the window covering to the inside of the window casing.
8 . The apparatus of claim 7 , wherein the mounting bracket comprises at least one of spikes, barbs, and cleats.
9 . The apparatus of claim 7 , wherein the mounting bracket is configured to remain in place on the window casing after removal of the window covering.
10 . The apparatus of claim 9 , wherein the moveable portion slides into and out of the mounting bracket.
11 . A method for installing a window covering, the method comprising:
providing a stationary portion for attachment to an end of a headrail of the window covering;
contacting an inside of a window ending with a moveable portion;
rotating a threaded member in order to translate the moveable portion relative to the stationary portion; and
providing an actuator to rotate the threaded member, wherein when the actuator is engaged the threaded member pushes against the stationary portion to create a compression fit between the headrail and the window casing.
12 . The method of claim 11 , wherein the actuator is a thumb wheel and engaging the actuator comprises turning the thumb wheel.
13 . The method of claim 12 , wherein turning the thumb wheel comprises using a tool inserted into an aperture on the thumb wheel.
14 . The method of claim 11 , wherein the actuator is a lever arm and engaging the actuator comprises exerting torque on the lever arm.
15 . The method of claim 14 , wherein the lever arm is a ratcheting lever arm.
16 . The method of claim 15 , further comprising using functionality on the ratcheting lever arm to reverse a ratcheting mechanism.
17 . The method of claim 11 , wherein the moveable port ion includes a mounting bracket to enable mounting of the window covering to the inside of the window casing.
18 . The method of claim 17 , wherein the moveable portion presses at least one of spikes, barbs, and cleats, incorporated into the mounting bracket into the window casing.
19 . The method of claim 17 , wherein the mounting bracket is configured to remain in place on the window casing after removal of the window covering.
20 . The method of claim 19 , further comprising removing the window covering by sliding the moveable portion out of the mounting bracket.
