TECHNICAL FIELD
The present application is directed to a screen assembly, for example and without limitations screen assemblies for use in office environments.
BACKGROUND
It is well known to use screens in different office environments, for example to partition separate workspaces, to act as sound barriers, to provide various display systems, such as marker boards, tack boards, and video screens, and/or to provide and/or increase privacy for various workspaces. Often, such screens are covered with a cover, such as a fabric, on one or both sides thereof, which may allow for customization of the appearance of the screen. The installation of such covers may be difficult, however, requiring the positioning and installation of various splines, caps, adhesives or other extraneous devices.
In addition, screens are often configured with a peripheral frame that provides a finished appearance to the screen and covers the edges of the fabric. Such frames often are difficult to install and increase the overall weight of the screen, thereby making the screens less portable or suitable for installation on desks and other locations.
SUMMARY
Briefly stated, in one aspect, one embodiment of a screen assembly includes a core having an edge and first and second opposite side surfaces. A retainer is coupled to the edge of the core and extends outwardly from the core. The retainer includes first and second resilient limbs having respective edge portions defining a mouth. The first and second resilient limbs define an interior cavity therebetween. The first and second resilient limbs define respective exterior surfaces. The edge portions of the first and second resilient limbs are movable toward and away from each other between a retention configuration and an insertion configuration, wherein the first and second limbs are biased toward the retention configuration. First and second cover portions each have an edge, with the first cover portion overlying the first side of the core and the exterior surface of the first resilient limb, and with the second cover portion overlying the second side of the core and the exterior surface of the second resilient limb. The first and second cover portions wrap around the edge portions of the first and second limbs and are disposed through the mouth such that the edges of the first and second cover portions are disposed in the interior cavity. The first and second resilient limbs retain the first and second cover portions therebetween.
In another aspect, one embodiment of a screen assembly includes a core having a bottom edge and first and second opposite side surfaces, and an edge treatment connected to the bottom edge of the core and extending downwardly from the core. The edge treatment includes opposing first and second limbs defining opposite first and second exterior surfaces. A first cover portion overlies the first side of the core and the first exterior surface of the edge treatment. A second cover portion overlies the second side of the core and the second exterior surface of the edge treatment. The first and second cover portions are held by the first and second limbs. A screen support includes an insert portion extending upwardly between the first and second limbs.
In yet another embodiment, a screen assembly includes a core having an edge and first and second opposite side surfaces, and an edge treatment connected to the edge of the core and extending outwardly from the core. The edge treatment includes opposing first and second limbs defining opposite first and second exterior surfaces and a mouth therebetween. A first cover portion overlies the first side of the core and the first exterior surface of the edge treatment. A second cover portion overlies the second side of the core and the second exterior surface of the edge treatment. The first and second cover portions are held by the first and second limbs. An accessory interface member has an insert portion disposed through the mouth between the first and second cover portions.
The various aspects and embodiments of the screen assembly provide significant advantages over other screen assemblies. For example and without limitation, in one embodiment, the cover can be easily and quickly installed without any extraneous fastening devices, for example splines, covers, etc. Moreover, once installed, the cover provides a continuous and uniform exterior appearance to the screen. In addition, the screen can be made relatively light weight, thereby increasing its portability.

Screen Assembly
Referring to FIGS. 1-3 and 7-15, a screen assembly 2 is shown as including a core 4 having a peripheral edge 6 and first and second opposite side surfaces 8, 10. As shown in FIGS. 1 and 2, the screen assembly may have a rectangular shaped side profile, or may have other non-rectangular quadrilateral or polygonal shapes, as shown for example in FIG. 13. The screen may also have various circular, obround, elliptical, oval, or other shapes. As such, the edges of the screen may be linear, or may be arcuate, or combinations thereof. The core 4 may be made of a single homogenous material, such as a lumber core, fiber board, fiber mat, foam core, including a polyurethane foam with a fiberglass mat filler, or may be formed of a various layers or substrates of such materials. The core may include one or more tackable layers, or sound barrier layers. The core may include an outer scrim 12 applied thereto, for example to provide fire retardant properties.
At least a portion of the peripheral edge, and in one embodiment, the entirety peripheral length of the edge, includes openings 14, 16 extending inwardly therefrom. The openings may be continuous, or spaced apart. In one embodiment, the openings are configured as first and second channels 14, 16 centered in the edge. The channels are nominally centered, but with thickness variances due for example to tolerance allowances, the channels may shift slightly off-center. In other situations, the grooves may be positioned closer to one side or the other as desired. The first channel 14 opens outwardly toward the edge 6 and has a first width. The edge defines a pair of landings 18 on each side of the channel. The second channel 16 extends inwardly from a bottom of the first channel 14 and has a second width, with the second width being less than the first width. In various embodiments, the core 4 is substantially planar, although it should be understood that the core may have a non-planar shape, for example being curved about one or more virtual vertical axes.
Referring to FIGS. 1-3 and 7-25, an edge treatment is coupled to the edge 6 of the core and extends outwardly from the edge, preferably within the same plane defined by the core. In one embodiment, the edge treatment is configured as a retainer 20 that includes a plurality of linear members 22 and a plurality of corner members 24. The linear members are preferably one piece, and are formed as an extrusion. The retainer may also include non-linear curved members that match the profile of the edge of the corresponding core. In one embodiment, the plurality of retainers 20 includes upper and lower retainer members, opposite side retainer members 22 and corner retainer members 24 positioned between the upper retainer member and the side retainer members and between the lower retainer member and the side retainer members. The corner retainer members are connected to the upper and lower retainer members. In one embodiment, one or the other of the corner retainer members and the upper and lower retainer members includes an insert portion 26 that mates with and is received in an opening formed in the other of the corner retainer members and the upper and lower retainer members comprise an opening, configured as an interior cavity 28 of the upper and lower retainer members in one embodiment, wherein the insert portion is disposed in the interior cavity.
The retainer, whether a linear member, a curved member or a corner member, includes first and second resilient limbs 30, 32 having respective edge portions 36, 38 defining a mouth 34, which may be closed, or form a slight gap, when in a retention configuration. The first and second resilient limbs 30, 32 define the interior cavity 28 therebetween. The first and second resilient limbs define respective exterior surfaces 40, 42. As shown in FIG. 3, the edge portions of the first and second resilient limbs 30, 32 are movable toward and away from each other between a retention configuration and an insertion configuration. The first and second limbs are biased together toward the retention configuration when no external forces are applied thereto. The edge portions 36, 38 may be configured to provide different profiles of the outermost edge of the screen assembly. For example, the limbs and edge portions may be shaped and configured to provide a triangular cross-section as shown in FIG. 3. Or the edge portions may be “squared off,” and have a relative flat and planar outermost surface.
The first and second limbs 30, 32 each have gripping members 44 extending inwardly into the interior cavity. The gripping members engage first and second cover portions 46, 48, e.g., fabric layers, inserted into the interior cavity 28 respectively. The gripping members 44 are oriented to provide one-way engagement of the cover portions 46, 48, such that the gripping members are configured to permit insertion of cover portions into the interior cavity, but prevent removal of the cover portions from the interior cavity. The gripping members may be configured as hooks, barbs, nodules, or other suitable protuberances. In one embodiment shown in FIG. 15, the gripping members 44 of the first limb 30 are staggered relative to the gripping members of the second limb 32, such that the covers 46, 48 may weave back and forth between the gripping members, thereby maximizing the gripping force exerted on the cover.
As shown in FIGS. 3 and 15, the exterior surfaces 40, 42 of the limbs are tapered from a base 50 adjacent opposite side surfaces of the core to the edge portions thereof. The exterior surfaces may be substantially planar as shown in FIGS. 3 and 15, or may be curved (concavely or convexly outwardly), or have a non-linear or non-planar profile as shown in FIGS. 8, 12, 16 and 17. The first and second limbs extend outwardly from the base, with the term “outwardly” defined as away from and generally within the profile of the core, e.g., radially “outwardly” from a screen having a circular, side profile. The base has a floor 52, which may include opposite, exterior bumps 54 that engage the landings 18 on the edge 6 of the core, and thereby ensure that the retainer 20 sits properly on the edge, for example due to warping or tolerance buildup along the edge. The base 50 includes an insert member 56 disposed in the channels of the core. The insert member may include a first portion 58 mating with and disposed in the first channel 14 and an anchor member 60 disposed in the second channel 16. The base, including the insert member, and limbs may be integrally formed, for example by extrusion. The width of the base may be varied to accommodate different core thicknesses. In one embodiment, the width of the base is slightly less than the width of the core.
Referring to FIGS. 18-25, the retainer 120 is formed from separate halves 122, 124 each defining one of the first and second limbs 130, 132. The halves may be connected with one or more fasteners, such as screws 126, or by a snap-fit engagement, adhesives, welding, e.g., sonic welding, and/or combinations thereof. The two-piece retainer is shown as being suitable for the corner members, or pieces, which are not suitable for extrusion due to the non-linear configuration. It should be understood that the linear pieces 320, 322, 324 (see FIGS. 6 and 21-25) and also may be made two-piece, and that the corner pieces could be molded as one piece. The linear pieces 322, 324 may be right and left handed, such that a combination of which includes aligned insert portion and anchor portions 330, and lugs 328 that receive fasteners to connect the halves. The corner pieces have first and second limbs 130, 132 that define first and second orthogonal mouth portions 134, 136. Each half is configured with an array of gripping members 140.
Referring to FIGS. 1-3 and 15, first and second cover portions 46, 48 (shown in partial view for the sake of clarity, are shown as each having a peripheral edge 70, 72 with the cover portions have a side profile generally matching the profile of the core and edge treatments, but with the cover portions having a larger surface area with the edge 70, 72 extending beyond the edge portions 36, 38 of the retainers on all sides of the screen. The first cover portion 46 overlies the first side of the core, including an scrim layers, and the exterior surface 40 of the first resilient limb 30. The second cover portion 48 overlies the second side of the core and the exterior surface 42 of the second resilient limb. The first and second cover portions 46, 48 wrap around the edge portions 36, 38 of the first and second limbs and are disposed through the mouth 34 between the edge portions and limbs 30, 32 such that the edges 70, 72 of the first and second cover portions are disposed in the interior cavity 28 wherein the first and second resilient limbs retain the first and second cover portions therebetween. The gripping members 44 of the first and second limbs engage the first and second cover portions. It should be understood that the cover portions may be formed as an integral sheet of material, for example with the cover portion wrapping around a bottom edge of the core and/or edge treatment, and with the free edges of the cover then being secured in retainers along the other three edges of the screen. The cover may also be sealed along the two other sides, or sealed along three sides, e.g. by sewing, with core fitting inside an envelope or bag-like structure formed by the cover. In this embodiment, the cover would include first and second portions formed along only one side thereof which are secured in a retainer. The cover portions 46, 48 may be secured to the exterior of the core and/or retainers with an adhesive.
Referring to FIGS. 38 and 39, another screen 500 is shown as having a core 502 formed from glass filed polyurethane foam. Linear edge treatments 506, formed for example as extrusions, and corner edge treatments 504, formed for example by injection molding, are positioned around the periphery of the core. In this embodiment the cover portions are omitted, with the core and edge treatments providing the finished appearance of the screen.
