Mounting system for window treatment
An adjustable mounting system for use with a variety of window treatments comprises a head rail, an adjustable support rod, and one or more clips for coupling the support rod to the head rail. The mounting system is preferably non-invasive and does not damage window casings. The mounting system may be installed very quickly and easily, without the need for any tools. The head rail is adapted for use with a wide variety of window treatment assemblies.
1. Field of the Invention
The present invention relates to mounting systems for window treatments.
2. Description of Related Art
Most systems for mounting window treatments include at least two brackets that are configured to receive a head rail of a window treatment. The brackets are fastened to the window casing or the wall in front of the window casing with screws, bolts, or nails, so that the brackets can support the head rail of the window treatment. This leaves holes and damage in the window casing or wall that must be repaired if the window treatment is replaced. On small window casings, such as those having a width of about four feet or less, only two brackets, one mounted adjacent each side of the window casing, are used. This often results in the middle portion of the head rail sagging over time. On larger windows, center brackets must be used to support the load of the head rail and window treatment.
Another disadvantage of these conventional mounting systems is that they can be very difficult and time consuming for an average consumer to install. For installations in which the brackets are screwed to the wall in front of the window frame, the widths of the brackets have to be measured, the brackets must be properly leveled, and pilot holes must be made, before the brackets can be mounted. This requires that the installer have certain tools and skills. Further, the installation of the brackets can cause permanent damage to the window casing or the wall to which they are mounted.
Some mounting systems do not require screw-mounted brackets. These non-intrusive mounting systems often use a supplemental cap or mounting bracket for one or both ends of the head rail. These independently functioning brackets are commonly spring-loaded or use a lever and cam system to generate compression. However, these supplemental caps have several disadvantages, as well. In particular, the compression that is achieved is often only great enough to support shear-type drapes and very light-weight curtains. Such brackets do not generate enough strength to support heavy rolling shades, mini-blinds, or drapes. In particular, after the window treatment has been opened and closed repeatedly, these types of brackets, much like conventional screw-in brackets, often must rely upon the strength and integrity of the head rail itself to support the window treatment. This often results in the middle portion of the head rail sagging over time.
Although great strides have been made in the area of mounting systems for window treatments, many shortcomings remain.

Support rod 104 comprises a tubular rod portion 110, a guide cutout 112, a sliding guide 114 that protrudes into guide cutout 112, an adjustment shaft 116, an adjustment collar 118, and end caps 120a and 120b. End caps 120a and 120b comprise coupling portions 121a and 121b and pad portions 123a and 123b, respectively. Support rod 104 has an adjustable length and is configured to be installed into a window casing 226 (see
Adjustment collar 118 preferably comprises a finger tightening portion 125 and an integral wrench tightening portion 127. Finger tightening portion 125 preferably includes gripping means that allow a user to get a firm hand or finger grip on adjustment collar 118. For example, in
Adjustment collar 118 is operably coupled to adjustment shaft 116. Although adjustment shaft 116 is free to translate axially according to the length of guide cutout 112, adjustment collar 118 restricts the movement of adjustment shaft 116 relative to support rod 104 by butting up against an end 119 of support rod 104. In this manner, rotation of adjustment collar 118 in the appropriate direction relative to adjustment shaft 116, causes adjustment shaft 118 and end cap 120b to translate outward away from support rod 104 and into contact with window casing 226, thereby forming a press-fit of mounting system 100 into window casing 226. Although mounting system 100 has been shown with a threaded coupling as a means for adjustment, it should be understood that other means for adjustment, such as ratchet systems and clamping systems may be utilized.
In the preferred embodiment, the length of head rail 102 matches the distance between the walls of window casing 226. This allows head rail 102 to conceal end caps 120a and 120b after installation. It should be understood that in some applications it may be necessary or desirable to trim head rail 102 to fit appropriately within window casing 226. The length of support rod 104 may also be trimmed, particularly from the end adjacent end cap 120a, to fit window casing 226.
It is preferred that the interior cross-sectional shape of head rail 102 and the exterior cross-sectional shape of at least one portion of end caps 120a and 120b be similar. This ensures that head rail 102 will conceal end caps 120a and 120b and not rotate relative to support rod 104 after installation. In the example of
Mounting system 100 may be installed very quickly and easily, without the need for any tools. First, support rod 104 is press fit into window casing 226, a process more fully described in
Another advantage of mounting system 100 is that the weight of head rail 102 and any associated window treatment can be more evenly distributed along support rod 104, thus preventing sagging. Clip members 106 serve to transfer and distribute loads from head rail 102, and any window treatment associated with head rail 102, through support rod 104 to window casing 226. Although only two clip members 106 are shown in
Referring now to
Next, adjustment collar 118 is tightened, i.e., rotated in one of the directions indicated by arrow 240, to force adjustment shaft 116 in the direction of arrow 235. This causes end cap 120b to be advanced toward window casing 226. End cap 120b is advanced in this manner until end cap 120a makes contact with window casing 226. As explained in more detail herein, end caps 120a and 120b may comprise compliant material or other means for positively engaging window casing 226. Thus, additional torque may be imparted upon adjustment collar 118 after the initial contact between end cap 120a and window casing 226. This ensures a firm press fit between support rod 104 and window casing 226. Support rod 104 may include means for preventing adjustment collar from loosening once tightened to the desired position. For example, a tension nut or retaining clip may be added to ensure that adjustment collar does not inadvertently loosen once tightened.

Clip member 106 is preferably made of any appropriate material, including but not limited to, plastic, metal, rubber, nylon, and others. However, clip member 106 may be varied in many ways, including size and shape, depending upon the particular implementation desired. In some alternative embodiments back portion 330 may not be present. In other alternative embodiments, top and/or bottom portions 332 and 334 may be missing or may extend to a greater or lesser extent from a back portion 330.
It is preferred that clip member 106 be securely fastened to head rail 102 at selected locations. This can be achieved by snapping clip member 106 into the interior portion of head rail 102, by press-fitting clip member 106 into the interior portion of head rail 102, by sliding clip member 106 into the interior portion of head rail 102, or other suitable means. In an alternative embodiment, clip member 106 is integrally formed with head rail 102. In another alternative embodiment, clip member 106 may be adjustably relocated along the length of head rail 102 by sliding clip member 106 within the channel formed by head rail 102.
It will be appreciated that clip member 106 may perform other functions in addition to releasably retaining head rail 102 to support rod 104. For example, clip member 106 may contain one or more string guides, apertures, notches, or slots, such as notches 360 and 362, to accommodate strings, cables, and other operating controls used to operate various window treatments associated with head rail 102.
