Furniture frame with interlocking joints for use with multiple furniture members and mechanisms
A furniture member frame includes a plurality of commercial grade plywood frame members connected to create a frame sub-assembly. A plurality of interlocking joints are defined by male extending members of first ones of the frame members and receiving apertures of second ones of the frame members. The interlocking joints operate when the male extending members of selected ones of the first ones of the frame members are received in the receiving apertures of the second frame members to temporarily connect the frame members. An adhesive applied to at least the interlocking joints fixedly connects the frame members of the first frame sub-assembly.
The present disclosure relates to furniture member frames adapted to separately receive a motion and/or footrest mechanism.
BACKGROUNDThe 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.
SUMMARYAccording 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. An adhesive applied between a contacting portion of each of the first member and the second member is operable to fixedly connect the first member to the second member to create a frame section.
According to other embodiments, a furniture member frame includes a plurality of commercial grade plywood frame members connected to create a first frame sub-assembly. A plurality of interlocking joints are defined by male extending members of first ones of the frame members and receiving apertures of second ones of the frame members. The interlocking joints operate when the male extending members of selected ones of the first ones of the frame members are received in the receiving apertures of the second frame members to temporarily connect the frame members. An adhesive applied to at least the interlocking joints fixedly connects the plurality of frame members of the first frame sub-assembly.
According to still other embodiments, a furniture member assembly includes a plurality of plywood frame members connected to create each of a first frame sub-assembly and a second frame sub-assembly. A plurality of interlocking joints defined by male extending members of first ones of the frame members are individually received within receiving apertures of second ones of the frame members to temporarily connect the plurality of frame members. An adhesive applied to at least the interlocking joints fixedly connects the plurality of frame members of the frame sub-assembly. A mechanism selected from a plurality of functionally different mechanisms is adapted to support each of the first and second frame sub-assemblies.
According to additional embodiments, a furniture member assembly includes a plurality of plywood frame members connected to create each of a first and second frame sub-assembly. A plurality of interlocking joints defined by male extending members of first ones of the frame members and receiving apertures of second ones of the frame members are operable when the male extending members are received in respective ones of the receiving apertures to temporarily connect the plurality of frame members of each of the first and second frame sub-assemblies. A mechanism is adapted to support the first frame sub-assembly and the second frame sub-assembly is connected to the mechanism independent of the first frame sub-assembly.

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”.

Similar to right side arm assembly 232, left side arm assembly 234 includes a left front leg 250 connected to a left arm post 252. A left arm inner support member 254 and a left arm outer support member 256 are connected between left arm post 252 and a left rear leg post 258. A left rear leg member 260 defines a homogenous extension of left rear leg post 258. A half lap joint similar to half lap joint 248 is also used to connect left arm inner support member 254 to left rear leg post 258. According to several embodiments, all of the component parts of base frame assembly 230 are created from a commercially available grade of plywood, except right front leg 236 and left front leg 250, which can also be made from a hardwood material due to their geometry, or from a composite material.
A left pan support member 262 is connected between left front leg 250 and left rear leg member 260.

Left side reclining portion 292 and right side reclining portion 296 are substantially a mirror image configuration of each other, therefore the following discussion of components used for left side reclining portion 292 applies also to right side reclining portion 296. Left side reclining portion 292 includes a base frame sub-assembly 314. A mechanism 316 is provided, such as the mechanism disclosed in U.S. patent application Ser. No. 11/328,772 entitled “Wall Proximity Reclining Chair With In-Line Linkage Mechanism”, filed Jan. 10, 2006, and commonly owned by the assignee of the present disclosure, the subject matter of which is incorporated herein by reference. A foot rest panel 318 is extendable by operation of mechanism 316. Base frame sub-assembly 314 is connected to a left side arm sub-assembly 320 and fixed with respect to base frame sub-assembly 314. A left side moveable frame sub-assembly 322 is connected to mechanism 316 for rotation from the upright position shown to a reclined position (not shown). One or more mechanism connection links 324 are used to fastenably connect mechanism 316 and thereby base frame sub-assembly 314 and left side arm sub-assembly 320 to each of the first and second track members 298, 300 using one or more L-channels 326. L-channels 326 are oriented substantially transverse to each of first and second track members 298, 300.

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.
