Technical Field

The present disclosure relates generally to upholstered furniture and, more particularly, to upholstered furniture comprising one or more molded parts.

Background

A upholstered seating having almost all exposed furniture items covered by a decorative covering is one of the largest volume items sold in the retail interior furniture market (if not the largest volume item), thereby providing one of the highest revenue sources for the retail furniture store. The market for such upholstered seating is highly competitive and any improvements in manufacturing result in improved products, higher value to the customer and/or lower manufacturing costs that would be welcomed by the industry. In manufacturing such upholstered seating articles, such as sofas, couches, lounges and the like, the structure of the upholstered furniture article is provided by a frame or chassis, which provides structural support to the furniture and provides its basic shape. Traditionally, frames for upholstered furniture items have typically been constructed from wooden materials, such as hardwood, softwood, engineered wood (e.g., plywood, chipboard, millboard, chipboard, and fiberboard). Portions of the wooden frame may typically be covered by padding or padding (such as foam), and may be subsequently covered with fabric, leather, hybrid fibers, faux leather, micro fibers, or other ornamentation. Wooden furniture frames are often heavy and have long assembly times due to the large number of parts and their material weight, in part because they include a large number of parts. For example, a single arm for upholstered chairs, couches and sofas may include up to and in excess of 10 or 15 different wood parts that do not include the numerous fasteners required for assembly. Of course, each wood part needs to be cut accurately. In addition, a single backrest for chairs, recliners, and sofas may include up to and in excess of 10 or 15 different wood parts that do not include the numerous fasteners required for assembly.

In addition, attaching the trim to the complex shaped wooden sofa frame arms can be very tedious because the wooden frame has gaps that need to be covered with cardboard or the like, the trim components (including the pad) do not slide over the wooden frame for positioning, and thus, the trim needs to be accurately positioned manually. Furniture manufacturers would be highly receptive to improvements that would facilitate the attachment of trim components to the sofa frame arms.

Furthermore, there is wood non-uniformity, the use of multiple pieces of wood in the construction of sofas and chair parts (such as arms) is only as strong as the weakest piece of wood, and can present difficult quality control problems. Further, when fasteners are driven into multiple pieces of wood during assembly of the furniture article, the pieces of wood may crack.

The process of manufacturing a upholstered furniture item described above is time consuming and expensive as the multiple parts must be assembled manually to construct the final upholstered furniture item. Thus, there is a need for a simplified method for manufacturing upholstered furniture items that provides a product that provides adequate support or improved levels of support and comfort to the user while reducing labor and material costs.

While efforts have been made to utilize plastic components in seating, such efforts have not been commercially successful in upholstered seating, and have not utilized the corresponding attributes and disadvantages of plastic and wood.

Disclosure of Invention

Embodiments of the present disclosure include upholstered seating in which the number of parts that need to be assembled is minimized for easier assembly, in which assembly time is minimized, and in which the finished product is robust and robust. The inventors have determined the optimal and cooperative use of polymeric structural components and non-polymeric structural frame components (such as wood frame members) to provide such attributes.

In an embodiment, a upholstered seating article configured as a sofa includes a seat base having a seat cushion, a upholstered back, and a pair of armrests having padding. The seat base, the cushion, and the pair of armrests are all covered with upholstery over all visually exposed areas, specifically the top and sides of the sofa. The sofa has a sofa frame or chassis including a pair of blow-molded armrest moldings spaced apart by a separation distance, and a plurality of cross-over wood frame members each extending between the pair of molded armrests, each cross-over wood frame member having a length greater than the separation distance and having wood frame member ends that are nested within recesses in the respective blow-molded armrest moldings. One or more of the plurality of wood frame members are attached to each of the pair of blow molded armrest moldings by a plurality of metal screws extending into a plurality of metal threaded inserts in the respective armrest moldings. An upright back frame member and a seat component are supported by and attached to the cross frame member. The upholstery covers the side armrest molding, the backrest, and the cushion such that substantially all of the exposed area of the sofa is covered by the upholstery.

Features and advantages of embodiments are: an article of furniture includes a pair of opposed arm member profiles, each integrally formed from a single piece of polymeric material. This structural arrangement provides ease of assembly and cost efficiency by minimizing the number of parts and minimizing the number of assembly steps. In an embodiment, a wooden cross member extends between the pair of opposing arm member profiles. In an embodiment, each arm member defines a plurality of respective recesses, each of the respective recesses being sized and positioned to receive an end portion of a wooden cross member. In an embodiment, a plurality of threaded metal inserts are supported by each of the arm members. Each of the threaded metal inserts may receive a threaded fastener that helps to constrain the wooden cross member relative to the arm members.

Features and benefits of the embodiments are: the upholstered article of furniture has a covering material in the form of an upholstered pocket positioned on at least a portion of the upholstered article of furniture, including each of the arm portions. In an embodiment, the trim pocket comprises a cushion that provides a higher level of comfort to a user of the upholstered article of furniture. In an embodiment, the upholstered article of furniture further comprises a liner: wherein at least a portion of each arm portion is covered by the pad such that the pad is located between the molded component and a covering material.

Features and advantages of embodiments are: an article of furniture includes a pair of opposed arm members, each of the arm members including a hollow shell comprising a polymeric shell wall having inwardly facing surfaces defining a void volume, the polymeric shell wall having a plurality of low friction polymeric outwardly facing surfaces. In an embodiment, the low friction polymer outwardly facing surface provided by the polymeric housing wall facilitates pulling of a trim cover material over the arm portion of the article of furniture. In an embodiment, the polymeric shell wall provides a support structure and provides a basic shape for the arm portion of the article of furniture.

Features and advantages of embodiments are: the article of furniture includes arm portions, each arm portion being integrally formed from a single piece of thermoplastic material. This arrangement allows the arm portion body to be prepared using an automated and efficient thermoplastic injection molding process.

Features and benefits of the embodiments are: an article of furniture includes an arm member having a cross-member receiving recess that orients a wooden cross-member of the furniture. In an embodiment, each of the cross-member receiving recesses is shaped and dimensioned to receive an end portion of a wooden cross member when the wooden cross member is disposed in a predetermined orientation relative to the arm members. In an embodiment, the arrangement facilitates fixture-less alignment and assembly of the sub-components.

Features and benefits of the embodiments are: an article of furniture includes an arm member having a plurality of mounting features. In the described embodiments, the plurality of mounting features allow the arm member to be used with a variety of furniture item types/furniture item models. Examples of items of furniture include sofas, couches, chairs, sectional sofas, seating units, sofa beds, futon frames, and reclining chairs.

Features and benefits of the embodiments are: the article of furniture includes an arm member defining a recess that receives a distal end of a cross member to form a tongue and groove joint. In an embodiment, the groove extends up and down along a groove axis. In an embodiment, the groove is shaped and sized to receive an end portion of a wooden cross member having a uniform thickness along its length. In an embodiment, the wooden cross member may be slid down with each end of the cross member received in a groove defined by opposing arm members to facilitate fixture-less alignment and assembly of the sub-components of the article of furniture.

Features and advantages of embodiments are: an article of furniture has an arm portion with less than three layers of material between the arm portion and the trim cover. In an embodiment, the arm portion has a top curved surface about a horizontal axis. In an embodiment, the layer between the arm portion and the trim cover comprises an EVA base layer and a second layer of fibrous material thereon. A feature and advantage of the arm portion is the absence of a layer of paperboard extending across the wooden frame as in many conventional assemblies.

Features and advantages of embodiments are: the number of parts required to assemble the lounge chair is greatly reduced, the assembly difficulty is greatly reduced, the assembly time is greatly reduced, and the cost is correspondingly greatly reduced, as compared to conventional lounge chairs. Furthermore, the structural integrity is generally greater.

In an embodiment, a method of making a upholstered seat comprises: providing a seat frame comprising a front frame member, an opposing backrest, and two arms at opposite ends of the front frame member and the backrest, wherein at least one of the front frame member and the opposing backrest comprises a wood component, and wherein the arms are made of molded plastic; coupling at least one of the arms to the wood part; and covering at least a portion of the arms with a covering material.

The characteristics and advantages are as follows: the inventors have found that staples can be received comparable to wood frame members using certain polymers, such as polyethylene. This facilitates the use of the polymer armrest molding in existing furniture assembly lines.

Features and advantages of embodiments are: the blow molded handrail stock can have a wall thickness of from 2mm to 6 mm. Such a thickness provides stability and secure retention of the frame members connected thereto while providing a more resilient handrail forming member than prior art wood handrail frames. Such resilience may reduce the amount of cushioning material required as compared to conventional wood frame handrail moldings.

In an embodiment, the attachment of the upholstery is simplified due to the very low coefficient of friction between the sofa arm molding and the upholstery material, allowing for an appropriately sized upholstery arm portion to slide easily over the arm molding. In embodiments, this facilitates construction of a more complete trim kit at a location remote from the final sofa assembly location of the sofa. For example, the trim kit may include an armrest sock portion that already has armrest padding attached to the trim cover material. This may eliminate the step of having to manually attach one or more padding layers at the final sofa assembly site prior to attaching the upholstered portion of the armrest.

Features and advantages of embodiments are: the degree of separation of the manufacturing locations of the components for the upholstered seating article is improved. For example, padding for an armrest may be attached to the armrest trim portion as part of the trim kit, at a location remote from the final seating assembly location. In addition, each of the armrest moldings may be molded at a location remote from the final seat assembly location and transported to the final seat assembly location.

Features and benefits of the embodiments are: an arrangement of furniture items in which the number of parts that need to be assembled is minimized and the assembly time is minimized, and which is robust and robust.

Features and advantages of embodiments are: the specific attributes of polymers and wood have been combined in a synergistic manner to construct a wooden frame or chassis for a upholstered seating. For example, conventional polymers (e.g., polyethylene) suitable for geometrically larger components, such as furniture components, may creep over time and may reduce load bearing strength when subjected to tensile or large shear loads. However, three-dimensional polymer moldings, in particular hollow polymer moldings, have a reasonable compressive load-bearing capacity. Downward loading will generally not cause significant creep of the polymer, making certain polymers (such as polyethylene) suitable for use in handrail moldings. In the case where such armrest moldings are used for some limited downward compressive loading, any reduction in the strength of the polymer over time should not affect the integrity of the sofa frame and sofa. Polymers have great capacity and flexibility in securing components such as discontinuously loaded wood frame members. In an embodiment of the invention, the load from the seat is not isolated from the polymer armrest molding, but rather the load is carried directly downward from the seat deck to a lower front rail and a lower rear rail, both of which are positioned at the lower edge of the sofa. Without feet on the sofa, the load from the seat would be transferred to the floor surface along the length of both the front and rear rails. In the event that there are feet on the sofa, the front and rear rails will act as end supported beams and the floor engaging feet will be positioned under the ends of the front and rear rails and transfer the load through the feet to the floor.

On the other hand, when properly oriented, the timber has a greater load bearing capacity between the support ends. The use of a wood-based cross-frame member in combination with the polymer armrest form to support the weight of a person sitting on a sofa provides sufficient strength to support the person sitting on the sofa and provides sufficient strength to support the person sitting on the sofa with minimal component parts, minimal assembly time, and potentially reduced cost. The optimal solution is to minimize the load bearing of the larger blow molded parts.

Features and advantages of embodiments are: a plurality of cross-over wood frame members are used between a pair of polymer armrest moldings, with the cross-over wood frame members carrying the seat load sitting on the upwardly facing surface of the polymer armrest. In an embodiment, the upwardly facing surface is a load bearing platform portion formed in an interior wall portion of a hollow armrest form, whereby the seat load transmitted to the platform portion through the ends of the cross-over wooden frame member is distributed to the inwardly facing wall portions on the upper, lower, front and rear portions of the platform portion. In an embodiment, the cross frame member may be constructed of metal rather than wood, with some of the same advantages.

Features and advantages of embodiments are: a blow molded polymer armrest form has a plurality of vertical recesses in the wall portion for increasing the structural strength of the armrest form. Features and advantages of embodiments are: polyethylene is used for the armrest form and the threaded insert has an internally threaded surface for receiving a screw that extends through the cross frame member to secure the cross frame member to the polymeric armrest form placed at the attachment point of the cross member in the polymeric wall portion. In an embodiment, the threaded insert has an external thread and is screwed into the polymer wall portion of the handrail forming member. In an embodiment, the attachment point of the cross member is located at a recess in the wall portion of the armrest profile, whereby an end of the cross member will be embedded in the recess, the embedder providing a secure fixation of the component relative to the armrest profile.

Features and advantages of embodiments are: a furniture seat article has a rectangular base, opposing side polymeric structural supports defining opposing short sides of the polymeric base, and a wood-based panel defining a long side of the rectangular base, ends of the wood-based panel being connected to the polymeric structural supports, and wherein the rectangular base supports a seat platform and a backrest, and wherein all load bearing components of the furniture seat article are connected directly to at least one of a front non-polymeric support and a rear non-polymeric support, or through metal or wood components. In other words, none of the loaded components will transfer any load on them exclusively to the polymeric structural support, such load being shared or primarily carried by the non-polymeric frame structure. In an embodiment, floor engaging feet are placed under the four ends of the wood base plate to support the load of the seat item. With the feet, the loads due to sitting are not carried by separate stand-alone polymer structures (such as legs) other than the sofa feet to carry the load of the furniture seating item.

In an embodiment of the invention, the armrests for a stationary upholstered seating article (such as a sofa) each have a hollow polymeric armrest form weighing from about 6 to 10 pounds, saving 10 to 16 pounds for both armrest forms compared to conventional wood frame armrest forms. In embodiments of the present invention, a lounge armrest molding may save 14 to 19 pounds with two blow-molded armrests as compared to a conventional wood frame armrest molding. In reclining chairs, the armrest can be reduced in weight by 50% compared to conventional wood frame armrests by using a blow molded polymer armrest form.

The above summary is not intended to describe each illustrated embodiment or every implementation of the present disclosure.
