Description:

FIELD

The present disclosure relates to furniture member frames adapted to separately receive a motion and/or footrest mechanism.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Conventionally, reclining articles of furniture (i.e., chairs, sofas, loveseats, and the like) require a mechanism to extend, stow, and to bias a leg rest assembly in the extended and stowed positions. Known mechanisms commonly include a large number of moving parts that tends to increase the manufacturing time and costs associated with the furniture. A frame structure of the furniture member is adapted to receive the mechanism. Common furniture member frames are capable of receiving only a single mechanism design, therefore multiple frame designs are required for example to provide furniture members having different functions such as rocking vice gliding actions.

Most reclining and rocking furniture members include an upholstered chair frame supported from a stationary base assembly in a manner permitting the chair frame to “rock” freely with respect to the base assembly. In order to provide enhanced comfort and convenience, many rocking chairs also include a “reclinable” seat assembly and/or an “extensible” leg rest assembly. For example, combination platform rocking/reclining chairs, as disclosed in Applicant's U.S. Pat. Nos. 3,096,121 and 4,179,157, permit reclining movement of the seat assembly and actuation of the leg rest assembly independently of the conventional “rocking” action.

Common frame structures include hardwood material to accommodate loads applied by the'seating support members such as sinuous springs, and to allow fasteners to be inserted in any exposed side or face of the frame without tear-out, and further to provide a material which receives fasteners such as staples to attach padding and upholstery. Hardwood used in these applications can be cost prohibitive. Wood laminate materials (i.e., marine grade plywood) have been used to mimic the strength of hardwood, but are expensive, add weight to the frame, and do not have acceptable tear-out strength when fasteners are inserted in a direction parallel to the laminate layers. Common frame designs are frequently upholstered with the mechanism attached, which requires the upholsterer to handle the weight of both the frame and mechanism. When this combined weight is too great to be manually manipulated, lifting fixtures are required, which increase the construction costs.

SUMMARY

According to several embodiments of a furniture frame for use with and without a mechanism of the present disclosure, a furniture member frame includes a plurality of plywood members including at least one first member having at least one male extending member. At least one second member having a receiving aperture is adapted to receive the male extending member to operably interlock the first member to the second member without the use of a fastener.

DETAILED DESCRIPTION

The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features. It should also be understood that throughout the specification, the terms forward refers to the direction faced by an occupant seated in the furniture member and rearward refers the direction facing away from or behind the occupant. Right or right hand and left or left hand, generally refer to the right side or left side of an occupant facing forward in the furniture member.

Referring generally to FIG. 1, a furniture member 10 of the present disclosure in the form of a rocking, reclining chair, includes a frame assembly 12 including each of a lower frame sub-assembly 14 and an upper frame sub-assembly 16. A mechanism 18 (shown in phantom) is located within lower frame sub-assembly 14 to provide support and a rocking, reclining capability for lower frame sub-assembly 14 and frame assembly 12 in general. Mechanism 18 is in turn supported by a frame support section 20 which can be positioned on a planar surface such as a floor. Mechanism 18 is exemplary of a plurality of mechanisms that can be used in furniture member frames of the present disclosure, therefore the specific description of the features of mechanism 18 do not limit the scope of the furniture member frames of the present disclosure.

A plurality of sinuous wire members 22 are suspended over a cavity 23 created within a frame pan 24 of lower frame sub-assembly 14 and connected to mechanism 18. Sinuous wire members 22 provide vertical support for the weight of an occupant of furniture member 10. According to several embodiments, sinuous wire members 22 are made of a spring steel material. Upper frame sub-assembly 16 provides a back or back rest support for an occupant of furniture member 10.

Referring now to FIG. 2, frame assembly 12 can be constructed as shown prior to installation of mechanism 18 or connection to frame support section 20. Frame assembly 12 can therefore be upholstered prior to installation of mechanism 18. Frame assembly 12 and frame assemblies of the present disclosure in general are constructed to the maximum extent possible using a laminated wood material, particularly one of the commercial grades of plywood. Multiple joints used to assemble frame assembly 12 are controlled tolerance joints to promote self locking between the various frame members, stiffeners, and braces. The structural strength of frame assembly 12 derives from the various joints and the use of an adhesive between the members. Fasteners when used in the construction of frame assembly 12 (and for frame assemblies of the present disclosure in general) are generally in the form of staples, brads, and the like which function to hold various joints in place while the adhesive cures, but are not relied on for structural strength.

Frame assembly 12 includes each of a first arm section 26 defining a right arm section and a second arm section 28 defining a left arm section. First and second arm sections 26 and 28 can be mirror images of each other, therefore, the following discussion of second arm section 28 applies equally to first arm section 26. A forward post 30 and a middle post 32 have a lower brace 34 connected between the forward and rear posts 30, 32. A first pan arm 36 of frame pan 24 is joined to forward post 30 and middle post 32. A corner brace 38 is connected between first pan arm 36 and forward post 30. An arm rest member 40 is also connected to each of forward post 30 and middle post 32 and also extends rearwardly of middle post 32 to connect to a rear post 42.

An adhesive 21 such as a wood glue is applied as a film or bead to one or both of the frame members to be joined between opposed contacting faces or surfaces of the members. For example, a contacting face 23 of the present disclosure can include an outwardly directed face of forward post 30′ where it is notched to receive lower brace 34′. The opposing contacting face 25 can include an inwardly directed face of lower brace 34′ which is received in the notch of forward post 30′. The contacting faces can also be an edge of a frame member that abuts a face or edge of a corresponding frame member. Adhesive 21 and the joints described herein together provide the mechanical strength to support the weight or load of an occupant of the furniture member without the use of additional “structural” fasteners, which are relied on for their mechanical or structural strength to hold opposed members together under load.

Lower brace 34 is connected to forward post 30 using a lap joint 44 and is similarly connected to middle post 32 using a lap joint 44′. Corner brace 38 is connected to first pan arm 36 using a tongue 46 which mates within a tongue cavity 48 created in first pan arm 36. Similarly, a second tongue 46′ of corner brace 38 is received in a tongue cavity 49 created in forward post 30.

Arm rest member 40 is connected to forward post 30 using a tenon 50 extending from arm rest member 40 which is inserted entirely through a tenon cavity 52 of forward post 30. Similarly, a tenon 53 of middle post 32 is received in a tenon cavity of arm rest member 40. A mortise and tenon joint 54 is created where first pan arm 36 is joined to forward post 30. Through tenon 50 of arm rest member 40 carries vertical loads from arm rest member 40 to forward post 30, and a half-lap joint created proximate to tenon 53 is positioned directly under arm rest member 40 to carry vertical loads of arm rest member 40 through middle post 32. Rear post 42 is connected to lower frame sub-assembly 14 using a tenon 56 extending from first pan arm 36 which is received within a tenon cavity 57 created in rear post 42. Also, a tongue 58 of rear post 42 defines a portion of lap joint 44′. A tenon at each end of a cross brace 59 which is oriented transverse to frame pan 24 is also received proximate to tenon 56 of tenon through cavity 57.

Each of the joints described above used to assembly first and second arm sections 26 and 28 are created to allow the members to be hand-assembled and adhesively bonded without the use of fasteners except when the manufacturer uses fasteners for temporarily holding the joints in place to allow the adhesive to set. For example, the use of fasteners such as staples can be used when creating the joints at lap joints 44, 44′, tongues 46, 46′, and tongue 58, as well as through arm rest member 40 proximate to tenon 53.

Upper frame sub-assembly 16 includes first and second upper frame posts 60, 60′ which have respective first and second upper frame wings 61, 61′ connected thereto. An upper frame first cross member 62 and an upper frame second cross member 63 provide horizontal stiffness and cross support between the upper frame posts 60, 60′. Each of the upper frame posts 60, 60′ are connected to extending links of mechanism 18 using a fastener bracket 64 connected to each of the upper frame posts 60, 60′. Fasteners (not shown) are connected through fastener brackets 64 and fastened using fastener nuts 66. By connecting upper frame sub-assembly 16 to mechanism 18, upper frame sub-assembly 16 is rotatable with respect to lower frame sub-assembly 14 about an upper frame arc of rotation “A”.

Referring to FIG. 3, frame support section 20 includes each of a first leg 68 and a second leg 70. A rear brace member 72 and a front brace member 74 provide horizontal stabilization of first and second legs 68, 70. One or more feet 76 can also be connected to a bottom or floor facing surface of each of first and second legs 68, 70. Feet 76 are made of a resilient material to resist slipping between first and second legs 68, 70 and a smooth floor surface.

To provide a planar surface for attachment of upholstery, a brace outer face 78 of tongue 46′ and a brace outer face 80 of lower brace 34 are positioned substantially co-planar with or recessed with respect to a planar edge surface 82 of forward post 30. A similar arrangement is provided for forward post 30′.

Referring to FIG. 4, a drive rod longitudinal axis 84 is positioned as shown when furniture member 10 is in its static position prior to rocking either forward or backwards. As viewed in FIG. 4, rocking motion of furniture member 10 will appear to displace drive rod longitudinal axis 84 either upwards or downwards from the position shown. The frame assembly joints and construction of the frame assemblies of the present disclosure allow mechanism 18 to be assembled independently of frame assembly 12. Frame assembly 12 is subsequently positioned over and supported by contact of frame pan 24 with each of support surfaces 78, 78 ′ of mechanism 18. Fasteners inserted through extension portions 67, 67′ of frame pan 24, and through corresponding apertures (not shown) of mechanism 18 fixedly connect frame assembly 12 to mechanism 18. When assembled, furniture member 10 has a frame first width “B” which according to several embodiments is greater than a frame second width “C”. Frame first width “B” can also be substantially equivalent to or smaller than frame second width “C” in other embodiments of the present disclosure.

Referring now to FIG. 5, furniture member 10 has several motions with respect to first and second legs 68, 70. Starting when furniture member 10 is positioned substantially in an upright and “non-rocked” position defined by a central axis 85, a rocking member 87 is supported by a leg upper surface 86 of both first and second legs 68, 70. From this position, furniture member 10 can rock forward about a forward arc of rotation “D” to a forward rocking limit 88. Furniture member 10 can also rock rearward in a rearward arc of rotation “E” to a rearward rocking limit 90. Independent of either of the rocking motions for furniture member 10 upper frame sub-assembly 16 can be rotated about a seat back arc of rotation “F” from the position shown to an upper frame rearward rocking limit 92.

Corner braces 478 can also be installed where upper ends of first and second frame side walls 462, 464 join upper brace 466, to minimize twisting of these members.

Referring now to FIG. 27, mechanism 316 is representative of a plurality of mechanisms which can be used in the furniture members of the present disclosure. For example mechanism 316 provides L-channels 326, 326′ which are fastened to each of first and second track members 298, 300 when creating furniture member 290. Mechanism 316 can also include a first foot rest support member 480, and a second foot rest support member 482 which are extended using a pantograph linkage set 484 to allow the foot rest (not shown) to be extended from a stowed to a fully extended position. Mechanism 316 can also provide both a first frame support member 486 and a second frame support member 488 on opposed sides of the mechanism. First and second frame support members 486, 488 include apertures adapted to receive fasteners (not shown) to fixedly connect seat pan assembly 328 to mechanism 316 before or after upholstery is applied to seat pan assembly 328.

Referring now to FIG. 28, when furniture member 290 is assembled as shown, a side wall 490 is connected to foot rest panel 318 defining a standoff distance “Z” between front post 332 and foot rest panel 318. As also shown, left side moveable frame sub-assembly 322 can be rotated about an arc of rotation “M” by clearance provided between a curved surface 492 of extended frame side 422 and a corresponding curved surface 494 of curved member portion 350.

Referring to FIG. 29, a clearance dimension “N” is created between center section 294 and left side reclining portion 292 to both provide for space for applied upholstery, and to allow subsequent rotation of left side moveable frame sub-assembly 322. A clearance dimension “P” is also provided between fixed front panel 312 and foot rest panel 318 to both provide for space for the applied upholstery, and to allow displacement of foot rest panel 318.

Referring now to FIGS. 30 through 33, a furniture member 496 includes a plywood frame sub-assembly 498 having a homogenous, one piece brace/seat pan 500. In FIG. 30 a handle 502 is attached to a mechanism which is operable when rotated to extend a leg rest 504 away from or to return the leg rest 504 back to a leg rest stowed position shown, and a backrest sub-assembly 506 is shown in a fully upright position. As shown in FIG. 31, handle 502 is fully rotated in a counterclockwise direction which extends the leg rest 504 to a fully extended position. As shown in FIG. 32, the leg rest 504 is in the fully extended position and the backrest sub-assembly 506 is shown rotated to a fully reclined position. As shown in FIG. 33, only the backrest sub-assembly 506 is rotated to its fully reclined position.

Referring back to each of FIGS. 6, 8, and 22, each of items 36, 130, and 328 define a plywood deck or pan member which according to several embodiments provides a central support member for the entire frame or frame assembly. The plywood deck or pan member a seat pitch angle, provides a substantially flat surface for a seat suspension (including sinuous wire members and clips), and provides a face laminate for attachment of a mechanism which supports the pan member and thereby the frame. In several embodiments, threaded fasteners can be inserted through the face laminate, thereby eliminating the need for secondary attachment devices such as tee nuts.

Each of the tenons and tongues described herein define male extending members of a first frame member received in “close tolerance” receiving apertures, slots, or notches of a second (or more) frame member(s) which together define an interlocking joint. Close tolerance apertures, slots, or notches (collectively referred to as receiving apertures) as described herein refer generally to apertures which are sized to receive the male extending member with an interference fit, a sliding fit, or a lap fit which temporarily interlocks the members to allow the joined frame members to remain together for a time period to allow an adhesive to cure which bonds the two (or more) frame members without the use of fasteners. The male extending members of the present disclosure can maximize joint strength by orienting the male extending members to receive applied loads from an occupant of the furniture member transverse to the overlapped layers of material. Fasteners including staples and brads described herein which optionally aid in assembly of the various frame members during the application of adhesives are “non-structural” fasteners, meaning the fastener is not subsequently relied on for its structural strength to hold the frame members together when an occupant weight or load is applied to the furniture member. The capability to hold the frame members together is provided by the combination of the joints provided and the use of adhesive(s) between contacting portions of the frame members.

Commercial grade plywood referred to herein is commonly identified as grade “CDX” type plywood, having no sanded or finished faces. Commercial grade plywood does not include “marine grade” plywood which is known in some furniture member applications because it can approximate the holding strength of a hardwood or softwood member when a fastener is received parallel to a plane defined between any joined pairs of the material plies. Marine grade plywood can be substituted for the furniture frame members of the present disclosure, but is not defined herein as commercial grade plywood.

The use of plywood for the frame members of the present disclosure also offers the advantage of material use efficiency. Many of the individual frame members such as the braces, corner braces, and stiffener members are made from material cut from the aperture or cavity areas of items such as the seat pan. Also, by nesting the various parts, it is possible to cut the individual frame members for a single frame from approximately a single 4×8 foot (1.22×2.44 m) sheet of plywood. It is further noted that seat pan thickness “H” can be a common thickness for all frame members of a frame or frame sub-assembly of the present disclosure. All frame members can therefore be cut from a single thickness of plywood, which permits a plywood sheet having a single inventory part number to be delivered to a work station for manufacture of the frame. This feature obviates the common practice to inventory and gather multiple parts with multiple inventory part numbers from a warehouse to manufacture a furniture frame.

The interlocking joints or features of the present disclosure permit the frame assemblies to be constructed without the use of ancillary fixtures to hold the parts. The frame therefore acts as its own fixture during assembly. Specialized assembly training for assembly personnel is therefore eliminated, and a reduced number of assemblers can be used to assemble frames of the present disclosure, further reducing construction costs.

Furniture members of the present disclosure offer several advantages. By using a commercial grade of plywood for substantially all framing components, the cost of the furniture member frames are reduced compared to commonly used materials such as hardwood and metal. By assembling the frames of the present disclosure using interlocking joints and adhesive, the frames of the present disclosure can be assembled without fasteners if desired, and connect using the advantageous overlapped strength provided by multiple, overlapped layers of the plywood material without fastening into the ends of the plies where tear-out strength of the plywood material is reduced. The all-plywood, interlocked frames of the present disclosure are also adapted to be upholstered before the frames are connected to a mechanism, which minimizes the weight of the frame assembly which must be manipulated during the upholstery phase. This further reduces handling complexity and cost of the resulting furniture member. Frames of the present disclosure are also adapted to receive multiple mechanism designs, permitting a single frame assembly to be used in multiple applications such as rocking/reclining members, rocking only members, leg rest extendable members, and the like. The mechanism when used in a furniture member sub-assembly of the present disclosure can be selected from a plurality of functionally different mechanisms, therefore furniture members of the present disclosure can support multiple furniture member platforms or types. The functionally different mechanisms can include but are not limited to rocking, reclining, rotating, fixed, leg rest extending, fixed leg panel, gliding, backrest fixed, and backrest rotatable designs, and the like. The furniture member types which are supported include but are not limited to chairs, love seats, sofas, ottomans, and the like.
