CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Application Number

62/633,575, filed February 21 , 2018 and U.S Provisional Application Number 62/774,852, filed December 3, 2018, the entire contents of which are incorporated by reference herein.

FIELD OF THE DISCLOSURE

This disclosure relates to furniture construction, and in particular, to the manufacture of upholstered furniture. More specifically, the disclosure relates to upholstery covers form fit to conventional wooden sofa frames and the integration of fastening means on the covers facilitating easy attachment to the frames.

BACKGROUND

In the manufacture of upholstered furniture, such as sofas, by way of example, love seats, chairs, and similar items, up hoi stery fabrics are typically secured to a frame through fixed fastening means.

Upholstery fastening means for sofas and chairs typically, by way of example, involve the use of fasteners, typically staples, but also including tacks, nails, screws, or other similar fasteners. Because these fasteners have a low tolerance for correction, the upholstery must be perfectly aligned before it is fastened to the frame. Such fastening is serial, that is, one after another such that only an incremental portion of the upholstery' is attached at a time. This can require continual alignment and positioning of the upholstery edge portions as they are atached. Moreover, the fabric and materials used for upholstery typically has some degree of stretchability such that as the upholster}- is attached it must be incrementally stretched. The currently employed methods of aligning the upholster}- is very- time consuming, and even minute errors can result in products with visible imperfections and inconsistency from one piece of furniture to the next. Thus training and skill levels are important for consistent quality product. Typically the edge portions are simply the cut edges of the upholstery fabric with no finishing such as folded over portions. The edge portions are of a non-critical length and simply stapled to exposed wood frame portions that are not readily visible, or that will be subsequently covered. For example, upholstery cover edge portions of the front, back, and arm rest sides of a sofa are pulled over the lower perimeter corner of a sofa frame and stapled to exposed wood on the bottom of the frame. These staples may be covered by a thin black dust cover that is also typically stapled to the frame.

Tools that can be required for applying the fasteners to the frame are relatively expensive, may be dangerous to operate, and require extensive training before operating. Securing the fabric may also require an exorbitant number of fasteners, driving up the cost to manufacture each piece of furniture. In some case, different installers utilize different numbers of fasteners to secure the fabric, resulting in difficulties tracking costs and materials, as well as yielding inconsistent results on the completed product. Further, after the upholstery is fastened to the frame, it is extremely time consuming to remove and replace for repairs. In some cases, removal attempts may permanently damage the upholstery fabric, the frame, or both.

Furniture manufacturers continually seek efficiencies in production costs. It is known to furniture manufacturers to manufacture upholstery' kits overseas, the kits including upholstery covers form fit to portions of furniture frames. The upholstery kits are shipped back to the United States for installation on the furniture frames. The tedious, costly, and somewhat hazardous task of installing the upholstery pieces to the frame often occurs in the United States, remote from the manufacture of the upholstery kits. The installation of the upholstery covers to the wooden frames typically requires the use of many, for example, hundreds of staples per sofa with the quality of the cover install being highly dependent upon the skill and training of the installer. Minimizing labor and parts costs, particularly the more expensive labor costs in the U.S., and making the process safer, and making the process less dependent upon the training and skill of the upholstery cover installer, would result in better manufacturing efficiencies, more consistent quality sofas, better value for the consumer, and would be well received by the industry .

For example, fastener strips 91 may be used to engage the form fit upholster cover to the breast rail 28, the top rail 26, and the back panel frame member 32 of the wood frame 22, in addition to other members. In embodiments, fastener stripping comprises one or more fastener strips 91 engaged with the breast rail 28 such that the one or more fastener strips 91 are disposed around at least two corners of the breast rail 28 capturing the breast rail. The length of the one of more fastener strips 91 may be limited by vertical wood sofa frame members 39 which intersect with the breast rail 28. In some embodiments, one or more fastener strips 91 secures a first material panel 112 of a form fit upholstery cover 100 to a breast rail 28 such that the first material panel 112 covers at least three comers of the breast rail 28. In some embodiments, a form fit upholstery' cover 100 may be stapled or similarly fastened directly to the breast rail 28 without the use of fastener strip 28 In embodiments, a form fit upholstery cover 100 may be stapled or similarly fastened directly to the breast rail 28 in addition to using the one or more fastener strips 91. In some embodiments, one or more fastener strips 91 engage with a top rail 26 such that the one or more fastener strips 91 are disposed around at least two comers 130 of the top rail 26. The length of the one of more fastener strips 91 may be limited by wood sofa frame members which intersect with the top rail 26. In such instances, cardboard strips, not shown, may be disposed between the one or more fastener strips 91 to supply additional rigidity to the upholstery material. In some embodiments, fastener stripping 91 secures a top edge 116 of a form fit upholstery cover 100 around a top rail 26 such that the form fit upholstery cover 100 covers at least three corners 130 of the top rail 26. The one or more fastener strips 91 may be positioned such that the first material panel 112 is held taught between the breast rail 28 and the top rail 26. When sufficient longitudinal force is exerted, the channel 95 of the one or more fastener strips 91 may be slid along the breast rail 28 or the top rail 26 to smooth out any wrinkles visible in the back material panel 118. In some embodiments, the one or more fastener strips 91 conforms the back material panel 118 around ail exposed visible edges of the breast rail 28 and the top rail 26 creating an aesthetic that can be appreciated by the user.

The fastener strips 91 may also, in embodiments, support straps 140 which substantially support the sofa user’s back. The straps 140 are sewn into the cover 100 and onto the fastener strips 91. In embodiments, straps 140 may be affixed directly to the breast rail 28, for example, with staples or similar means.

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 1 18 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. 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 1 18, 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.

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 comers 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.

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.

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 upholster}' panel 209 are secured underneath the wooden sofa frame 180. In some embodiments, one or more el astic 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.

Arm rest covers may contain any combination of fastener strips 91 and elastic fasteners 101. Fig. 17 illustrates an arm rest cover 351 being pulled over right arm rest 33 and having elastic fasteners 101 along peripheral edge portions of the arm rest cover 351. The outside material panel 367 is pulled back to reveal a fastener strip 91 affixed along the portion where the top material panel 375 and outside material panel 367 meet and is further configured to engage cross bar member 47. In embodiments, elastic fasteners 101 may be pulled around the frame members of ar rest 33 and engage corresponding anchor member receiving portions 303. In embodiments, elastic fasteners 101 may engage corresponding tabs (not shown) stitched to portions of the arm rest cover 351 in a“cover to cover” configuration. In embodiments, elastic fasteners 101 may be fed through components attached to other upholstery kit pieces thereby enhancing the security of all attachment points and ensuring upholstery kit components are firmly held in place. In embodiments, cardboard or other semi rigid material, not shown, may be affixed between cross bar member 47 and right side 73 to support top material panel 375 and any additional cushioning installed therebetween.

Fig. 18 illustrates a sample frame member of the sofa frame 22 having anchor member receiving portions designed to accept and retain the anchor member 103 of an elastic fastener 101 . In some embodiments, the anchor member receiving portion may be a notch 304 along an edge of a frame member such that an elastic fastener 101 may be pulled from a first side of a frame member and around the edge of the frame member, such that the elastic cord 102 aligns with and fits into the notch 304. The anchor member 103 of the elastic fastener 101, being wider than the notch 304, remains on an opposite side of the frame member and held in place under the force of elastic cord 102 shrinking back to its original unextended size. In some embodiments, the anchor member receiving portion is defined by a hole 303 through the frame member, the hole 303 further having one or more slots extending radially from the hole 303. The hole 303 is wide enough to permit the anchor member 103 of an elastic fastener 101 from one side of the frame member to an opposite side of the frame member. The radial slot is wide enough to permit the elastic cord 102 to pass from one side of the frame member to an opposite side of the frame member, yet the radial slot is too narrow to permit the anchor member 103 to pass from one side of the frame member to an opposite side of the frame member. This permits an installer to secure an elastic fastener 101 to a frame member of the sofa frame 22 by exerting suffici ent force to pull the anchor member 103 of the elasti c fastener 101 completely through the anchor member receiving portion and then guiding the cord into the radial slot. When the installer releases the elastic fastener 101, the force of elastic cord 102 returning to its previous unextended state is sufficient to pull the anchor member 103 against the frame member, thereby securing it in place, as the anchor member 103 is unable to return through the radial slot.

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.

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 fastners 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 w ? ood sofa frame.

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.
