1. Field
The invention relates to window treatments and more particularly to adjustable suspension system for window treatments, such as curtains.
2. Description of the Related Art
Window treatments for privacy and security are known in the art, including shades, blinds and curtains. Since window treatments are customarily hung from the top of a window, and because windows may extend out of reach in many instances, users must often employ a ladder or chair to reach a curtain rod or other device from which window treatments are hung. Due to the frequency with which users remove window coverings for either cleaning or replacement, a persistent hazard of injury from falling exists.
There is therefore a need for a window treatment suspension system that avoids the need for users to employ a ladder, a chair, or reach up while standing in an otherwise precarious position. In accordance with one aspect of the present invention, an adjustable window treatment suspension system is provided that allows users to reach the attachment mechanism of a window treatment from a standing or even sitting position. These and other objects of the invention will be further described in the following detailed description and illustrations.
In accordance with one embodiment, an adjustable window treatment suspension system is provided. The system comprises a support frame attachable to a wall and bordering a window frame, sliding door frame or opening. The support frame has a support plate attachable to the wall, a cross-bar attached to the support plate and extending outward therefrom, and a face plate attached to the cross-bar and extending downward therefrom. A first pulley is attached to one end of the support frame and second and third pulleys attached to an opposite end of the support frame. The system also comprises an attachment frame suspended relative to the support frame via pulley cords that engage the first, second and third pulleys, the pulley cords comprising a first pulley cord secured to one end of the attachment frame that engages the first and second pulleys and a second pulley cord secured to an opposite end of the attachment frame that engages the third pulley. The attachment frame has one or more coupling members configured to couple to one or more connection elements of a curtain removably attachable to the attachment frame via the coupling members. The one or more coupling members are slidable relative to the attachment frame to allow at least a portion of the curtain to slide to one side of the attachment frame to allow a user to view through the window, sliding door or opening. The attachment frame is movable from a raised position where it is disposed behind the face plate and one or more lowered positions via actuation of the pulley cords by a user, thereby allowing the user to detach a curtain from the attachment frame while in a seated or normal standing position and without using a ladder or chair to remove the curtain.
In accordance with another embodiment, an adjustable window treatment suspension system is provided. The system comprises a valance frame attachable to a wall bordering a window frame, the valance frame having a support plate attachable to the wall, a cross-bar attached to the support plate and extending outward therefrom, and a face plate attached to the cross-bar and extending downward therefrom. A first pulley is attached to one end of the valance frame and second and third pulleys attached to an opposite end of the valance frame. The system also comprises an attachment frame suspended relative to the valance frame via pulley cords that engage the first, second and third pulleys, the pulley cords comprising a first pulley cord secured to one end of the attachment frame that engages the first and second pulleys and a second pulley cord secured to an opposite end of the attachment frame that engages the third pulley. The attachment frame has one or more hooks configured to couple to a curtain removably attachable to the attachment frame via the one or more hooks, the one or more hooks being slidable relative to the attachment frame to allow at least a portion of the curtain to slide to one side of the attachment frame to allow a user to view through the window. The attachment frame is movable from a raised position where it is disposed behind the face plate and one or more lowered positions via actuation of the pulley cords by a user, thereby allowing the user to detach a curtain from the attachment frame without using a ladder or chair to remove the curtain.
Other features and advantages of the present invention will be apparent from the following detailed description of the invention, taken in conjunction with the accompanying drawings of which:
The attachment frame 10 can be of any dimension suitable for a particular curtain installation (e.g., have a length suitable for the particular size of, for example, the window or slider door that it will be used with). In one embodiment, the attachment frame 10 can have a length L1 of about 66¾ inches and a width of about one inch. The attachment frame 10 can also have pulley cord attachment points 16, 18 near each end of the frame 10 for attaching a pulley cord 32, 34, from which the attachment frame 10 will depend. The pulley cords 32, 34 can extend upward from the attachment frame 10, to engage pulleys P1, P2, P3 aligning with the left and right sides, respectively, of the attachment points 16, 18. The pulleys P1, P2, P3 can be supported on a support frame 20 (e.g., on a cross-member 28 of the support frame 20), which can be attached to a support surface (e.g., wall W surrounding the window or slider door) via one or more fasteners 22 (e.g., screws, nails, bolts). In the illustrated embodiment, the pulley cord 32 engages a third pulley P3 and attaches to the attachment frame 10 at attachment point 18; the pulley cord 32 extends downward from the third pulley P3 to one or more attachment members 50 attached to a support surface (e.g., a wall W). Similarly, the pulley cord 34 attaches to the attachment frame 10 at attachment point 16, then extends upward to engage a first pulley P1, then extends across a width of the support frame 20, supported by one or more support members 24 (e.g., hooks), and engages a second pulley P2, after which the pulley cord 34 extends downward to the one or more attachment members 50. In the illustrated embodiment, two attachment members 50 are attached to a support surface (e.g., the wall W) with a fastener 52 (e.g., a screw, bolt, nail, etc.). In one embodiment, each of the pulley cords 32, 34 can be attached to separate attachment members 50. In another embodiment, the pulley cords 32, 34 can both be attached to the same attachment member 50.
As best seen in
In one embodiment, the pulley cords 32, 34 can have variable lengths, allowing one pulley cord 34 to extend across the valance 26, such that both pulley cords 32, 34 are located on a single side of a window, slider door or opening that the curtain 2 is used to cover when installed. As discussed above, one or more attachment members 50, cord retainers, string attachments, or tensioners can be disposed on the wall W (or support surface) adjacent the window, slider door or opening for anchoring the pulley cords 32, 34 in place, thereby holding the attachment frame 10 (to which the curtain 2 or window treatment is attached) inside the valance 26 and hidden behind the face plate 27.
Referring to
Still referring to
As discussed above, the pulleys P1, P2, P3 are installed on the top of the valance 26. As shown in
In use, the user can detach the pulley cords 32, 34 from the attachment members 50 and lower the attachment frame 10, again attach the pulley cords 32, 34 once the attachment frame 10 has been lowered to within reach of the user, thereby allowing the user to remove the curtain 2 (or window treatment) from the attachment frame 10 (e.g., by removing the curtain 2 from the hooks 14). The user can then replace the curtain 2 with another curtain or window treatment, or can launder the curtain 2. The replacement curtain 2 can then be attached to the attachment frame 10 (e.g., by attaching the curtain 2 to the hooks 14 of the attachment member 10) and the user can pull on the pulley cords 32, 34 to raise the attachment frame 10 behind the face plate 27 of the valance 26. Once in the raised position, the user can securely attach the pulley cords 32, 34 to the one or more attachment members 50 to hold the attachment frame 10 in the raised position. The user can actuate the cord 36 (e.g., by pulling it) to open the curtain 2 to allow a user to view through the window, slider door or opening covered by the curtain 2. As discussed above, the curtain can be pulled completely to one side of the attachment frame 10 or can open from the middle outward so that portions of the curtain 2 are pulled to both sides of the attachment frame 10.
Though embodiments above describe the hooks 14 as attached to the attachment frame 10 and the curtain 2 attaching to the hooks 14 (e.g., via holes in the curtain 2), in other embodiments, the hooks 14 can be disposed on the curtain and the attachment frame 10 can have a plurality of holes that can receive the hooks 14 to couple the curtain 2 to the attachment frame 10, said holes formed on a slidable track that can allow the user to open the curtain 2 once installed by pulling on the cord 36 as discussed above.
Advantageously, the system 100 allows a user to easily remove curtains 2 (or window treatments) from the attachment member 10 while seated or standing without having to reach up to the top of the window, slider door or opening. Accordingly, the user can avoid having to use a ladder, chair or reach precariously for the top of the window to remove a curtain 2 or window treatment for replacement or laundering, thereby inhibiting injury to the user. The system 10 can advantageously allow users of all capabilities (e.g., incapacitated and in a wheel chair, elderly) to operate the system 10 easily remove and replace curtains 2 or window treatments from a window frame assembly.
Although the present specification describes a manual pulley based system for adjusting the position of the attachment frame 10 relative to the support frame 20, in other embodiments, the attachment frame 10 can be moved relative to the support frame 20 via a motorized or electric system (e.g., using one or more electric motors that rotate the one or more pulleys P1, P2, P3 or that pull on or extend the pulley cords 32, 34 to raise or lower the attachment frame 10 relative to the support frame 20.
Although the present specification shows and describes a preferred embodiment of the adjustable window treatment suspension system, it is anticipated that other embodiments are possible, inasmuch as the invention has been described by way of example and not limitation. Thus, it is intended that the present description cover the modifications and variations of the apparatus and method provided they come within the scope of the appended claims and their equivalents.
