FLEXIBLE, PROFILE BAR SCREEN

Abstract

A flexible, profile-bar-based screen is provided includes a flexible cord (e.g., a braided stainless-steel cable) that strings together several cross members (e.g., profile bars) in a pattern to create the screen. Flexible spacers ensure that the cross members remain generally parallel, while allowing the cord to flex in any direction. Each end of the cord includes a cap (e.g., nut, washer, tacking, etc., combinations thereof) to prevent edge cross members from falling off the cord.

DETAILED DESCRIPTION

A flexible, profile-bar-based screen is provided includes a flexible cord (e.g., a braided stainless-steel cable) that strings together several cross members (e.g., profile bars) in a pattern to create the screen. Flexible spacers ensure that the cross members remain generally parallel, while allowing the cord to flex in any direction. Each end of the cord includes a cap (e.g., nut, washer, tacking, etc., combinations thereof) to prevent edge cross members from falling off the cord. Usually at least two cords are used to prevent the cross members from rotating about the cord.

Such a flexible, profile-bar-based screen has several advantages over traditional profile bar screens. For example, the flexible, profile-bar-based screen can wrap around curved walls instead of being limited to straight walls, provide a curved transition between a wall and a ceiling, or go up/down a staircase. Further, the flexible, profile-bar-based screen can be made in bulk and sold as a roll, where users can then cut to whatever size is required for a specific application and then add the caps. On the other hand, the ends of the screens may include couplers (shoulder bolt and keyhole lock, bead chain, S-hook, snaps, toggle latch systems, etc.) that allow one screen to be coupled to another screen.

Further, with existing profile bar screens, a tray is used to lock and hold the profile bars (i.e., cross members) in place. However, no such tray is needed (and would not be practical for any pattern except a flat pattern) for the flexible profile bar screens described herein.

Turning now to the figures, and in particular FIG. 1, a flexible screen 100 is shown with four flexible cords 102a-d and several cross members 104. The flexible cords 102a-d may be made of any strong, flexible material (e.g., braided stainless steel cable, chain, solid or braided metals, solid or braided plastics, etc.). Further, the cross members 104 may be any desired material (e.g., profile bar). The cords 102a-d run through the cross members 104 at apertures 106 within the cross members 104. As the cords 102 are flexible, they may flex in any direction to create shapes with curves in either direction (e.g., a convex curve 108 with an outside of the curve near a top of the cross members, a concave curve 110 with an outside of the curve near a bottom of the cross members).

Spacers 112 are between the cross members 104 to ensure spacing between the cross members 104. For example, the spacers 112 can ensure the cross members 104 remain generally parallel to each other looking from the top down (i.e., the cross members are each generally orthogonal to the cord). The spacers 112 themselves are also flexible. For example, each spacer 112 may be a coiled spring (e.g., compressed springs, extended springs) that surround a portion of the cord 102 between the cross members 104. Other types of spacers 112 may be used as well (rubber spacers, a stainless steel bead, stainless steel beads in series, etc.), but the spacers 112 should be flexible between the cross members 104.

Each of the ends 114 of the cords 102 has a cap 116 that prevents the edge cross members 104a-b from falling off the cords 102. The caps 116 can be anything that would prevent the edge cross members 104a-b from falling off the cords 102 (e.g., thick washers larger than the apertures, nuts larger than the apertures, tacking, crimping, etc., or combinations thereof).

FIG. 2 illustrates a side view of the flexible, profile-bar based screen 100 in a flattened position. The profile bar cross members 104 each include a stem 118 and a flat head 120. In the flattened position, the stems 118 are generally vertically parallel as shown in FIG. 2. Further, the flat heads 120 are horizontal. Moreover, the profile bars 104 (i.e., the cross members) are parallel in the depth direction, as shown in FIG. 3. As shown in FIGS. 2-3, spacing between the profile bars 104 is uniform. However, the spacing between the profile bars 104 may be different (i.e., variable).

Further, the spacing between profile bars 104 along the first cord (see FIG. 1, 102a) may be different than the spacing between the same two profile bars along the second cord (see FIG. 1, 102d). Such an arrangement allows for the screen 100 to lay flat in a circle (e.g., as a grate around a tree).

Turning now to FIG. 4, the flexible, profile-bar based screen 100 is shown shifted from the flattened position to a sinusoidal position. From the side view, the spacing of the cross bars 104 along the cord 102 remains essentially the same throughout due to the flexible spacers 112. However, the stems 118 are no longer parallel, and the heads 120 do not make a flat surface. On the other hand, a view from the top will show that the heads cross members themselves are still parallel from that angle. Thus, using the flexible cord 102 allows users to curve the screen to fit different shapes, as discussed above.

The screens as described herein may be mounted to walls, ceilings, stairs, etc. via any standard coupler (e.g., track system, bus bars, eyelets and cords, tension system (see FIG. 5), standoffs, glue mounting systems, hook and loop fasteners, S-hooks, etc.). FIG. 5 illustrates a tension system 138 that includes a channel 140 for the flexible screen to enter and wrap back on itself creating tension. Such tension can fix a flexible screen as an anchor point.
