(45) Fastener Strips
(46)
(47) In other embodiments,
(48) A fastener strip 91 may comprise a unitary homogenous and resilient material capable of flexing open to be placed around a member of the furniture frame 22 under the force exerted by an installer. For example, the fastener strip 91 may comprise a resilient polymer material. When the channel 95 engages the wood sofa frame 22, at the three legs 92, 93, 94 of the fastener strip 91 extend around two corners and three sides of the wood frame member. Surprisingly, it was determined through experimentation and measurement that a fastener strip 91 is less likely to pull off the wood frame member when the fastener strip 91 is aligned such that short leg 93 is placed on the wood frame member in the same direction as the tension force as applied by the upholstery cover. The fastener strip 91 is permanently affixed to the form fit upholstery cover at an edge portion of the cover by stitching, sewing, gluing, or other means known in the art. The fastener strip 91 may be affixed to the form fit upholstery cover along a single side. In one embodiment, the fastener strip 91 is affixed to the form fit upholstery cover by a continuous longitudinal stitch substantially along the center of the channel 95, thereby affixing the bottom side 94 to the form fit upholstery cover. In another embodiment, the fastener strip 91 is affixed to the form fit upholstery cover by a continuous longitudinal stitch through the long leg 92 and running parallel to channel 95, thereby affixing the left side 92 of the fastener strip 91 to the form fit upholstery cover. In all of the embodiments herein staples or other fasteners may be used to fix the fastener stripping in place.
(49) In embodiments, the channel 95 may be formed of other materials other than a polymer and may be more or less resilient. The channeled fastener strip may be attached to the upholstery by other means than stitching, for example staples, for example adhesives, for example, a molten polymer, or other means. Although the channeled fastener strips are illustrated as linear, in embodiments they may be curved to follow, for example, the curvature at a corner of a wood sofa frame. In embodiments the form fit upholstery cover may be applicable to a single seat upholstered chair.

(69) In some embodiments, one or more fastener strips 91 engage with a back panel frame member 132 such that the one or more fastener strips 91 are disposed around at least two corners 130 of the back panel frame member 132. The length of the one of more fastener strips 91 may be limited by furniture frame members which intersect with the back panel frame member 132. In some embodiments, fastener stripping 91 secures a back material panel 118 of a form fit upholstery cover 100 around a back panel frame member 132 such that the form fit upholstery cover 100 covers at least three corners of the back panel frame member 132. The one or more fastener strips 91 may be positioned such that the back material panel 118 is held taught between the back panel frame member 132 and the top rail 26. In some embodiments, the one or more fastener strips 91 conforms the back material panel 118 around all exposed visible edges of the back panel frame member 132 creating an aesthetic that can be appreciated by the user.
(70) In some embodiments, the fastener is one or more pulls 107 stitched or otherwise affixed to the edge portion of back material panel 118. In some embodiments, the fastener is one or more elastic fasteners 101 attached directly to an edge portion of the back material panel 118 such as through, eyelets, fabric pieces 105, or perforations in the material. The fastener is drawn underneath the sofa frame 22 and forms a taught connection with a corresponding fastener secured to an edge portion of front upholstery panel 209. The fastener may be positioned such that the back material panel 118 is held taught between the back panel frame member 32 and the top rail 26 when the opposite end of the fastener is securely engaged with a corresponding fastener secured to an edge portion of front upholstery panel 209. In embodiments, the fastener conforms the back material panel 118 around all exposed visible edges of the back panel frame member 32 creating an aesthetic that can be appreciated by the user. In embodiments, a rod or other rigid material, such as an elongate polymer strip, may be affixed to an edge portion of the back material panel 118, thereby ensuring the edge portion of the cover does not bunch up in any one area along the sofa frame 22. In embodiments, the edge portion of the cover may be folded around the rod or other rigid material and stitched, thereby securing the rod or other rigid material in place. In embodiments, the edge portion of the cover may be folded back and stitched into place, defining a pocket into which a rod or other rigid material may be slid. In embodiments, the elastic fastener 101 may be secured about the rod or other rigid material.
(71) Regarding the seat deck assembly 201, the one or more fastener strips 91 affixed to the right panel 206 may be rigidly engaged to the aperture 72 in right side 73, and the one or more fastener strips 91 affixed to the left panel 207 may capture the side board 250 of the sofa frame 180. In some embodiments, one or more fastener strips 91 engage with a bottom edge 69 of the front panel 274 such that the one or more fastener strips 91 are disposed around at least two corners 277 of the front panel 274. The length of the one of more fastener strips 91 may be limited by furniture frame members which intersect with the front panel 274. When sufficient longitudinal force is exerted, the channel 95 of the one or more fastener strips 91 may be slid along the bottom edge 279 of front panel 274 to properly fit front upholstery panel 209. In some embodiments, the one or more fastener strips 91 conforms the front material panel 209 around all exposed visible edges of the front panel 274 creating an aesthetic that can be appreciated by the user.
(72) In embodiments, the left panel 207 may be secured in place as one or more elastic fasteners 101 engage with frame members of the wood sofa frame 22. In embodiments, one or more elastic fasteners 101 affixed to the right panel 206 may pass through aperture 72 in right side 73 and engage with corresponding receiving holes in right side 73. In embodiments, elastic fasteners 101 attached to front upholstery panel 209 are secured underneath the wooden sofa frame 180. In some embodiments, one or more elastic fasteners 101 attached to front upholstery panel 209 are pulled across the bottom of the wooden sofa from and engage with corresponding fabric loops affixed along the edge portion of the back cover. In other embodiments, the one or more elastic fasteners 101 attached to front upholstery panel 209 are tied to the anchor member of elastic fasteners affixed along the edge portion of the back cover.
(73) Arm rest covers may contain any combination of fastener strips 91 and elastic fasteners 101.
(74)
(75) The embodiments of the present disclosure can provide the following advantages that can reduce installer training or errors during installation. In embodiments, an anchor member receiving portion may be strategically placed on a frame member of a sofa frame 22 in such a manner that the anchor member receiving portion may only be reached by a single elastic fastener 101, thereby eliminating the possibility that an installer would secure the wrong elastic fastener 101 to the anchor member receiving portion. In another embodiment, the length of the elastic cord 102 can be predetermined such that the elastic fastener 101 can only reach a single anchor member receiving portion, thereby eliminating the possibility that an installer would secure the elastic fastener 101 to the wrong anchor member receiving portion. In other embodiments, the elastic fastener 101 and anchor member receiving portion can be color coded or labeled with a letter, shape, or other symbol to reduce installer error. For example, a red elastic fastener 101 might be matched with a red hole 303 while a blue elastic fastener 101 is matched with a blue notch 304. In another example, the elastic fastener 101 may be labelled with a letter “A,” and matched to a anchor member receiving portion with a similar letter “A.” In embodiments, the anchor member 103 may be color coded or labelled. In embodiments, the anchor member receiving portion may have multiple colors or labels. For example, a hole 303 may have a first radial slot with a first label and a second radial slot with a second label.
(76) Installers may take additional measures, not shown, in furtherance of the goal of creating an aesthetically pleasing upholstered sofa. For example, exposed seams and loose edges are generally unsightly. Such unsightly portions might exist where different pieces of the upholstery kit abut one another. For example, on the back side of the sofa, an unsightly seam might exist where an upholstery cover abuts an arm rest cover. This unsightly seam might be hidden, for example, by having the upholstery cover slightly overlap the arm rest cover, and placing strips of hook and loop fasteners along the overlapping portions of the covers so that the hook and loop fasteners hold the covers together yet are hidden from the user's view. The portion of the hook and loop fastener closer to the wood sofa frame could be stapled or otherwise affixed to the frame such that when the cover portions are connected they are held taught. In another example, a dust cover, such as cambric or other known materials, could be stretched across the bottom of the sofa and affixed to the frame with staples or other similar fasteners. The dust cover would hide unsightly fastening means such as straps, elastic fasteners, and fastening strips, as well as other unsightly components such as raw wood frame members or the underside of a textile deck assembly. The fasteners used to secure the dust cover may be further useful in ensuring that components of the upholstery kit do not slide on the frame after installation, thereby maintaining its aesthetically pleasing appearance for a longer period of time. It is further understood that installers may use staples or other alternative fastening means on portions of the upholstery kit that are not conducive to the use of elastic fasteners or fastener strips according to embodiments of this disclosure. Installers may also use staples or other alternative fastening means as anchor points or starting points when disposing pieces of the upholstery kit about a wood sofa frame.
(77) Upholstery kits may be manufactured domestically or in foreign factories. In some instances, advantages such as cheaper upholstery materials or cheaper textile labor may offset shipping costs to ship upholstery kits from foreign manufacturing facilities to domestic assembling facilities. Wood sofa frames, because of their weight and bulk, and not so easily shipped overseas and are generally manufactured domestically. Assembled frames and upholstery kits may be received by an installer to attach the upholstery kit to the wood sofa frame in accordance with embodiments of this disclosure. In some instances, the wood sofa frame manufacturing site may also act as the location for installation. A fully assembled upholstered sofa may then be shipped to a distribution center. In some instances, a distribution center may be 100 miles or further from the installation site. In some instances, a distribution center may also serve as a retail facility. From the distribution center, a fully assembled upholstered sofa may be shipped either to a retail facility or directly to the home of a purchaser. In some instances, retail facilities or purchaser homes may be located 100 miles or more from the distribution center.
