The present disclosure generally relates to upholstered furniture and, more particularly, upholstered recliners including molded forms for receiving upholstery.
Upholstered seating furniture where essentially the entirety of the exposed furniture items are covered by upholstery is one of if not the highest volume items sold in the residential retail furniture markets and thereby provides one of the highest revenue sources for retail furniture stores. The market for such upholstered seating furniture is fiercely competitive and any improvements in manufacturing resulting in an improved product, better value to the customer, and/or lower manufacturing costs are welcomed by the industry.
In the manufacture of such upholstered seating furniture items, such as sofas, love seats, recliners, and similar items, the structure for the upholstered furniture items is provided by a frame or chassis, which gives the furniture structural support and also provides its basic shape. Traditionally, frames for upholstered furniture items have been typically constructed of wood materials, such as hardwood, softwood, engineered woods (for example, plywood, hardboard, millboard, chipboard, and fiberboard). Portions of the wooden frame may typically be covered by padding or cushioning, such as foam, and then covered with fabric, leather, synthetic fabric, faux leather, microfiber, or other upholstery. Due to the large number of parts and the weight of their materials, wooden furniture frames are often heavy and have long assembly times due, in part, to the large number of parts they include. For example, a single arm alone for upholstered recliners, recliners, and sofas can include up to and over 10 or 15 different wood parts not including the multitude of fasteners, typically staples, needed for assembly. Each wood part, of course, needs to be precisely cut. Further, a single back rest for a chair or recliner can include up to and over 10 or 15 different wood parts not including the multitude of fasteners.
Additionally, attaching upholstery to the complex shape of wooden sofa frame arms also can be painstakingly tedious in that the wooden frames have gaps that need to be covered with cardboard or the like, the upholstery components, including padding, does not readily slide on the wood frame for positioning and as such, the upholstery needs to be precisely positioned by hand. Upholstery is typically painstakingly placed, manually pulled about and stapled onto wood frame members. Although staples are inexpensive and easily utilized, they are not easily removed if service of the component is needed. Any improvement in ease of attaching upholstery components to seat components, particularly allowing the easy removal, without removing staples, would be well received by furniture manufacturers.
Moreover, due to non-uniformity of wood, the use of multiple wood pieces in constructing sofa and chair components, such as arms, is only as strong as the weakest wood piece and can present difficult quality control issues. Moreover, wood pieces can crack when fasteners, are driven into the pieces during assembly of the furniture item.
The above-described process of manufacturing upholstered furniture items is time consuming and costly due to the number of parts must be manually assembled to construct the final upholstered furniture item. As such, there is a need for a simplified method for manufacturing upholstered furniture items that reduces labor and material costs while providing a product that provides a sufficient or improved level of support and comfort to the user.
Although there have been efforts to utilize plastic components in seating furniture, such efforts have not been commercially successful with regard to upholstered seating furniture and have not taken advantage of the respective attributes and disadvantages of plastic and wood.
With respect to recliners, the incorporation of the recliner mechanism, whether motorized or non-motorized, into the framework of the recliner requires secure structural support of the recliner mechanism above the floor, allowing the recliner mechanism to movably support the recliner components such as the back rest, the footrest or ottoman, the seat, and the arm rests. The presence of the recliner mechanism and the cooperation of the various parts make assembly of recliners more tedious and challenging than sofas or a chair with no moving components. Applying upholstery to such recliners is also more challenging due to the relative movement of the components with respect to each other. Moreover, the wood frame of recliner components are more challenging to construct than sofas or non-moving seats in that the individual components that move with respect to other components have to be structurally strong and independent. That is, for example, the back rest moves with respect to the seat and arm rests so it cannot be immovably attached to the seat and armrests and therefore must be structurally independent, attached only to the recliner mechanism. Constructing these components of wood and steel parts is tedious and challenging.
Any improvements in recliner construction methods that simplify the manufacture and that make the manufacturing less labor intensive and would be welcomed by the furniture industry and result in lower costs to the manufacturers and to the purchasing public.
The embodiments of the present disclosure include upholstered seating furniture in which the number of components that need to be assembled is minimized, in which the assembly is simpler, where the time for assembly is minimized, and where the finished product is robust and sturdy.

A feature and advantage is that the inventors have discovered that utilizing certain polymers, such as polyethylenes, can received staples comparable to wood frame members. This facilitates utilization of the polymer arm rest forms in existing furniture assembly lines.
A feature and advantage of embodiments, a blow molded arm rest form may have a nominal wall thickness of from 2 to 6 mm. This thickness provides stabilization and secure holding of frame components connected thereto, while providing an arm rest form that is more resilient that a prior art wooded arm rest frame. In embodiments, the top wall portion of the arm rest form may be deflected more than .5 inches under loading, for example under a 100 lb. loading of a hand or foot of a person and will return to the original position when the loading is removed, the arm rest form is not damaged. In embodiments, the top wall portion of the arm rest form may be deflected more than .75 inches in localized regions under loading, for example under a 100 lb. loading of a hand or foot of a person, and the localized region of the top wall will return to the original position when the loading is removed, the arm rest form is not damaged. In embodiments, each of the top side wall portion, the two lateral side wall portions, the forward side wall portion, the rearward side wall portion, and the bottom side wall portion may be deflected .5 inches and each said side will return to the original position without damage. In embodiments, each of the top side wall portion, the two lateral side wall portions, the forward side wall portion, the rearward side wall portion, and the bottom side wall portion may be deflected .75 inches and each said side will return to the original position without damage. In embodiments, each of the top side wall portion, the two lateral side wall portions, the forward side wall portion, the rearward side wall portion, and the bottom side wall portion may be deflected 1.0 inches and each said side will return to the original position without damage. Such resilience can reduce the amount of cushioning material needed compared to conventional wood framed arm rest form and can provide an increased measure of safety over a wood framed arm rest when, for example, an individual inadvertently collides with or falls onto the arm rest.
A feature and advantage of embodiments is that the pair of blow molded arm rest forms each have a rearward face of a significant area to interface with the lower rearward rail or cross member and a defined recess in the face to receive end portions of the rail or cross member. These interfaces provide a high degree of rigidity to position the arm rest portions and in a precise rectangular geometry when initially assembled and secure that rectangular geometry during assembly, transportation, and ultimately use for the life of the recliner.
A feature and advantage of embodiments is the entire laterally outward wall surface of each polymer arm rest form is comprised of a single unitary closed wall with minimal apertures extending through the wall to the interior of the form. The apertures positioned at fastener locations for securing the arm rest form to another component. A feature and advantage of embodiments is the entire laterally inward wall surface of each polymer arm rest form is comprised of a single unitary closed wall with no apertures extending through the wall except associated with attaching other components.
A feature and advantage of embodiments of blow molded polymeric arm rest forms and a back rest form is that each may have one wall, the inner wall joining the outer wall at junctures interior a periphery of the blow molded form. These junctures can be at openings or windows defined in the blow molded form or at locations where no opening extend through the blow molded form
A feature and advantage of embodiments, a seat with a pair of blow molded arm rest forms may have a nominal wall thickness of from 2 to 3.5 mm, where the vertical walls or upper walls of the arm rest forms do not carry the majority of the loading of persons or pets on the seat. Rather the loading bypasses the vertical walls or upper walls of the arm rest forms and pass through other structural members. A feature and advantage of embodiments, a blow molded arm rest form may have a nominal wall thickness of from 2 to 3.5 mm, where upright portions of the arm rest form do not carry the majority of the loading of persons or pets on the seat.
In embodiments, attachment of the upholstery is simplified by the very low coefficient of friction between the sofa arm form and the upholstery material, allowing conformingly sized upholstery arm portion, such as socks, to be readily slid over the arm forms. In embodiments, this facilitates construction of more complete upholstery kits at locations remote from the final sofa assembly site of the sofa. For example, upholstery kits can include arm rest sock portions that already have arm rest padding attached to the upholstery covering material. This can eliminate the steps of manually having to attach one or more layers of padding at the final sofa assembly site before attaching the arm rest upholstered portions. Back rest forms similarly may have upholstery coverings with padding or recesses for padding sewn and assembled at a remote location with the coverings shipped to an assembly location of the seat.
A feature and advantage of embodiments is that segregation of manufacturing sites for components of the upholstered seating furniture items is enhanced. For example, padding for arm rests can be attached to arm rest upholstery portions as part of an upholstery kit in remote locations from the final seating furniture assembly location. Additionally, the arm rest forms may each be molded at a location remote from the final seating furniture assembly location and transported to the final seating furniture assembly location.
A feature and benefit of embodiments is an arrangement for furniture items in which the number of components that need to be assembled is minimized, is simple to assemble and the time for assembly is minimized and is robust and sturdy.
A feature and advantage of embodiments is a recliner where the arm rests are supported exclusively by a seat deck frame facilitating application of a form fit upholstery covering attached and secured with a zipper and no staples. A feature and advantage of embodiments is a form fit upholstery cover that attaches to a back rest form without any staples. A feature and advantage of embodiments is a form fit upholstery covering for a seat deck that is attached to and secured without any staples. In each of these upholstery coverings, removal and repair or replacement is much easier that conventional recliners, and assembly steps are quicker, less labor intensive, less prone to quality control issues.
A feature and advantage of embodiments is that the specific attributes of polymers and wood have been combined in a synergistic fashion for construction of a chassis for upholstered seating furniture. For example, conventional polymers suitable for geometrically large components, such as furniture components, for example polyethylenes, when subjected to tensile loading or significant sheer loading may creep over time and may lose load carrying strength and may effectively collapse. Although, three-dimensional polymer forms, particularly hollow polymer forms have reasonable compressive load carrying capabilities depending on loading. That is downward weight loading will not generally cause noticeable creep of the polymer making certain polymers such as polyethylenes suitable for arm rest forms.
The inventors have discovered that a thin walled blow molded arm rest may be supported off of the floor surface by a conventional recliner mechanism utilizing vertical columns formed by the thin wall of the arm rest form. The bracket providing ample support and strength in connecting the arm rest form to a metal framed seat deck using a reinforcing plate attached to the exterior side of the arm rest forms at the column, and having a threaded connector, such as a bolt, extending from the seat deck through the arm rest form and connecting with the reinforcing plate. In embodiments of the invention, no loading from seating is isolated on the polymer arm rest forms, rather the loading is carried directly downward from the seat deck to a recliner mechanism to the floor. That is the seating loading does not extend through the polymer arm rest forms to the floor surface. The recliner mechanism may have floor engaging feet.
A feature and advantage of embodiments is that a spanning wood frame member extends between and is attached to a pair of spaced hollow polymer arm rest forms, each end of the spanning wood frame member received in a form fit recess that abuts the edge surface and rear face of the spanning wood frame member.
A feature and advantage of embodiments are blow molded polymer arm rest forms that have a plurality of through openings defining on or more vertical columns in the arm rest forms in the wall portions for adding structural strength to the arm rest form. One such column receiving a plate for connection of the seat deck assembly. A feature and advantage of embodiments are blow molded polymer back rest forms that have a plurality of through openings defining one or more columns and horizontal beams in the back rest forms in the wall portions for adding structural strength to the back rest form.
A feature and advantage of embodiments is use of a polyethylene for arm rest forms, and with threaded inserts having an internal threaded surface placed at spanning member attachment points in polymer wall portions for receiving screws that extend through spanning frame members for securing the spanning frame members to the polymer arm rest forms. In embodiments, the threaded inserts have an external thread and are threaded into the polymer wall portions of the arm rest forms. In embodiments the spanning member attachment points are at recesses in the wall portions of the arm rest forms whereby an end of the spanning member will nest into the recess, the nesting providing secure fixation of the component with respect to the arm rest forms.
A feature and advantage of embodiments is a polymer arm rest form that has an exterior surface that is deflectable throughout the surface upon impact that is greater than any deflection of a conventional wood arm rest frame. In embodiments, all exterior corners of the polymer arm rest form have a radius of 0.5 inches or greater defined by the curvature of a corner wall portion providing deflection upon impact and a more blunt impact corner than conventional wood frame arm rest forms. In embodiments, all exterior corners of the polymer arm rest form defining the profile of the arm rest form have a radius of 0.75 inches or greater defined by the curvature of a corner wall portion.
In embodiments of the invention, arm rests for a stationary upholstered seating item such as a recliner, each have a hollow polymer arm rest form weighing from about 6 to 10 lbs, saving 10 to 16 pounds for both arm rest forms compared to conventional wood framed arm rest forms. In embodiments of the invention, recliner arm rest forms can save 14 to 19 pounds for two blow molded arm rests compared to conventional wood framed arm rest forms. In recliners, a 50% reduction in the weight from the arm rests is available by using blow molded polymer arm rest forms over conventional wood framed arm rests.
In embodiments of the invention, the inventors have facilitated utilizing hollow thin-walled, blow molded structures, such as chair arm rests, in load carrying applications by providing reinforcing means to the blow molded structures. Such reinforcing mean including metal or wood plates, or beams inserted into receiving pockets formed in the blow molded structure. In embodiments, the plane of a plate is positioned upright in a pocket defined in the blow molded structure for enhancing the load carrying capability. In embodiments, a hollow blow molded structure has a wood or metal reinforcing plate or beam on one lateral side of the blow molded structure and has another metal or wood load carrying structure on an opposite lateral side of the blow molded structure.
In embodiments, a blow molded back rest form, such as for a recliner, can have metal reinforcing arms inserted within the blow molded back rest form that attach to metal couplings for connecting with the recliner mechanism. The wall of the blow molded back rest form may be sandwiched and compressed between the metal coupling and the reinforcing arms.
In embodiments, a recliner may be efficiently and quickly assembled utilizing preformed blow molded arm rest forms and preformed blow molded back rest form, and a conventional recliner seat base with a generally rectangular frame, and a conventional recliner mechanism that is attached below the seat base frame. In embodiments, metal female threaded fasteners are secured to or in the arm rest forms. And metal attachment brackets are secured to the back rest form. Form fitting upholstery coverings are attached separately to each of the four components. The arm rest forms are bolted to the seat base, a recliner mechanism is bolted to the assembled seat base and arm rest assembly, and the back rest is attached to extending bracket receiving prongs of the recliner mechanism.
