Combination spring tension rod and mounting brackets for window coverings
View Patent ↗A combination spring tension rod and mounting bracket assembly easily mounts within a window opening. The spring tension rod includes a pair of elbow-shaped receptacles including a first and second arm defining an angle greater than 90°, wherein each first arm is mounted on opposite ends of the rod and the second arm defines a receptacle for a respective mounting bracket. Each of a pair of mounting bracket devices is mounted into the respective receptacle. The spring tension rod is compressed and positioned such that bearing surface portions of the bracket devices extend into the window opening. The spring tension rod is then released and forces the obtusely-oriented bearing surfaces to bear against opposed and facing surfaces of the window opening when installed. The spring force of the spring tension rod retains the rod and brackets in the installed position.
1. A bracket assembly for use with a spring tension rod for hanging window coverings, the bracket assembly comprising:
a mounting section defining a bearing surface facing in a first direction; and
a rod interface coupled to the mounting section and facing in a second direction generally opposite the first direction, the rod interface adapted to connect with one end of the spring tension rod,
wherein the rod interface is arranged relative to the bearing surface to position the rod interface spaced away from a window opening in a direction generally perpendicular to the first and second directions when the bearing surface is borne against a surface of the window opening, and
an elbow section coupled to the mounting section and defining the rod interface, the elbow section having a first arm and a second arm, wherein the first arm and the second arm define an angle greater than 90°.
2. A bracket assembly according to claim 1 , further comprising:
an elbow section coupled to the mounting section and defining the rod interface;
wherein the mounting section and the elbow section are separate parts; and
wherein the mounting section has a male attachment mechanism received in a female receptacle end of the elbow section.
3. A bracket assembly according to claim 2 , wherein a snap detent feature is provided between the attachment mechanism and the receptacle end.
4. A bracket assembly according to claim 1 , wherein the mounting section further comprises:
an anti-rotation tab extending outwardly in the first direction relative to the bearing surface and generally perpendicular to the bearing surface, the tab positioned to prevent downward rotation of the spring tension rod when installed; and
a sharp pointed tang extending outwardly in the first direction relative to the bearing surface and generally perpendicular to the bearing surface.
5. The bracket assembly of claim 1 , wherein the first leg and the third leg are outwardly biased relatively to each other.
6. The bracket assembly of claim 1 , the mounting section including a flat section that comprises the bearing section and the first leg.
7. A hardware assembly for mounting window coverings, the hardware assembly comprising:
a spring tension rod having a pair of opposite rod ends and a longitudinal rod axis, each of the opposite rod ends including an elbow section defining an angle of greater than 90° relative to the longitudinal rod axis; and
a pair of mounting brackets, one mounting bracket coupled to a female receptacle end of each elbow section, each of the mounting brackets including;
a rod interface connected to the female receptacle end of the elbow section; and
a bearing surface coupled to the rod interface and extending radially outward relative to the rod axis,
wherein the mounting brackets connect to the rod interface; and
wherein the bearing surfaces of the respective mounting brackets face generally outwardly opposite one another and in line with the respective female receptacle end of the elbow section to resiliently bend toward one another to bear against opposed surfaces of a window opening when installed.
8. A hardware assembly according to claim 7 , wherein the opposed surfaces of the window opening are not parallel.
9. A hardware assembly according to claim 7 , wherein the spring tension rod is length adjustable.
10. A hardware assembly according to claim 7 , wherein each bearing surface is provided on a corresponding mounting section of each mounting bracket.
11. A hardware assembly according to claim 10 , wherein the elbow section and mounting section of each mounting bracket are discrete parts assembled to one another.
12. A hardware assembly according to claim 10 , wherein the mounting section of each mounting bracket includes a male attaching mechanism received in a female receptacle of the respective elbow section.
13. A hardware assembly according to claim 10 , wherein the elbow section and the mounting section of each mounting bracket in combination include a snap-in detent when assembled.
14. A hardware assembly according to claim 7 , further comprising:
at least one anti-rotation tab positioned adjacent the bearing surface of each mounting bracket, each anti-rotation tab extending generally perpendicular to and in the facing direction of its respective bearing surface.
15. A hardware assembly according to claim 7 , further comprising:
a sharp pointed embedding tang positioned adjacent the bearing surface of each mounting bracket, each sharp pointed embedding tang extending generally perpendicular to and in the facing direction of its respective bearing surface.
16. A hardware assembly according to claim 7 , further comprising:
a fastener opening provided through a portion of the bearing surfaces of each of the mounting brackets for receiving a fastener when installing each mounting bracket.
17. A method of mounting a spring tension rod for hanging window coverings over a window opening, the method comprising the steps of:
providing a spring tension rod having a rod axis and opposed ends biased away from one another and compressible toward one another;
attaching a pair of mounting brackets, one to each of the opposed ends of the spring tension rod, each of the mounting brackets having a mounting section connected to an elbow section, each elbow section defining an angle of greater than 90°, a rod interface on the elbow section connected to a respective one of the opposite ends of the spring tension rod, a bearing surface on the mounting section and extending radially outward relative to the rod axis, and a sharp pointed tang extending from adjacent each of the bearing surfaces and generally perpendicular to the respective bearing surface;
rotationally aligning the pair of mounting brackets with one another about the rod axis;
fitting the spring tension rod to the window opening by compressing the spring tension rod opposed ends and mounting brackets toward one another;
placing the bearing surfaces adjacent corresponding opposed and facing surfaces of the window opening with the spring tension rod spaced outward from the window opening; and
releasing the spring tension rod such that the bearing surfaces are borne against the opposed and facing surfaces of the window opening.
18. A method according to claim 17 , wherein the step of attaching further includes forming an anti-rotation tab extending from each of the hearing surfaces and generally perpendicular to the respective bearing surface, and wherein the step of placing further includes positioning each of the anti-rotation tabs borne against a forward facing surface adjacent the window opening.
19. A method according to claim 17 , wherein the step of attaching further includes forming an anti-rotation tab extending from adjacent each of the bearing surfaces and generally perpendicular to the respective bearing surface, and wherein the step of placing further includes positioning each of the anti-rotations tabs borne against a forward facing surface adjacent the window opening.
20. A method according to claim 19 , wherein the step of attaching further includes forming a sharp pointed tang extending from adjacent each of the bearing surfaces and generally perpendicular to the respective bearing surface, and wherein the step of releasing causes each tab to embed in one of the opposed and facing surfaces of the window opening.
