Description

FIELD OF THE INVENTION

The present invention relates generally to a furniture assembly, and more specifically, to modular components that interconnect to form various forms of the furniture assembly.

BACKGROUND OF THE INVENTION

A considerable number of conventional items of furniture are available in the furniture marketplace, including for example, leather, fabric, wood, and other options. Construction and assembly of a conventional item of furniture is cost and labor intensive. Because overall design is a prime driver of sales, development, and production of furniture items, industrialized and standardized production and delivery thereof is limited and efficiency is extremely low. Present modular furniture designs are limited to the disassembly of the furniture itself, which has no practical significance. Moreover, the hardware connectors used in existing modular furniture suffer from deficiencies and low practicability such that modular furniture does not appear to a significant extent in the furniture marketplace.

For example, one conventional sofa that is misleadingly touted as a “modular” sofa includes at least two matching sofa monomers having insertion holes. During construction of the furniture assembly, the sofa monomers are positioned adjacent and a connecting nail is driven into the insertion holes to connect the monomers together. After the monomers are connected and the sofa is assembled, the monomers are difficult to disconnect. In fact, disassembly is difficult, being prone to damaging the monomers and/or requiring tools or excessive force. Additionally, it is necessary to set insertion holes on the sofa monomers, which requires additional effort and tools. As a result, processing, delivery, and installation costs for such a conventional sofa are high, rendering this type of sofa to be in true form a non-modular sofa. Accordingly, such a non-modular sofa is not conducive to modular commercial utility or consumer appeal. The present disclosure provides a solution for these and other problems.

The word “including” means “including without limitation.” Moreover, words of approximation, such as “about,” “almost,” “substantially,” “approximately,” and the like, can be used herein to mean “at,” “near,” “nearly at,” “within 3-5% of,” “within acceptable manufacturing tolerances of,” or any logical combination thereof. Similarly, terms “vertical” or “horizontal” are intended to additionally include “within 3-5% of” a vertical or horizontal orientation, respectively. Additionally, words of direction, such as “top,” “bottom,” “left,” “right,” “above,” and “below” are intended to relate to the equivalent direction as depicted in a reference illustration; as understood contextually from the object(s) or element(s) being referenced, such as from a commonly used position for the object(s) or element(s); or as otherwise described herein.

Referring to FIG. 1, a modular furniture assembly 100 includes two modular adjacent components that are configured to securely lock with each other. According to one example, the furniture assembly 100 is in the form of a sofa. The securely locking is achieved with modular assembly that allows quick, easy, and toolless assembly and/or disassembly. In this illustration, the furniture assembly 100 includes a modular recliner 102 and a modular universal base 104.

In other examples, the furniture assembly 100 includes other combinations of two or more modular components, the modular components being any of the modular recliner 102 and the modular universal base 104. For example, in an alternative combination the furniture assembly 100 includes a modular recliner 102 that is adjacent to and securely locked with another modular recliner 102 (instead of the illustrated modular universal base 104).

In yet another example, the furniture assembly 100 includes a modular recliner 102 that is adjacent to and securely locked with a modular universal base 104, which is adjacent to and securely locked with another modular recliner 102. Thus, in this example, the furniture assembly includes three components—two modular recliners 102 along the edges, with a modular universal base 104 in-between.

Referring to FIG. 2, the modular recliner 102 has a recliner base 106, a backrest module 108, and an armrest module 110. The armrest module 110 is modularly attachable to, and movable between, the modular recliner 102 (as illustrated in FIG. 2) and the modular universal base 104 (as illustrated in FIG. 1). For ease of understanding, the armrest module 110 is described below in attached form to the modular recliner 102.

The recliner base 106 has a generally flat top surface 112 for supporting a cushioning component (not illustrated). Thus, the flat top surface 112 provides the structural support for the cushioning component, which typically includes a shaped foam that offers comfort and support to a person resting on the modular recliner 102. The shaped foam includes, for example, a high density foam material.

One exemplary benefit of the flat top surface 112 is that it increases options for modularity and customization of the furniture assembly 100. While prior furniture assemblies require a recliner assembly to have an inclined (or angled) top surface, the present disclosure advantageously described the flat top surface 112 on which a variety of inclined cushioning components can be attached. In other words, the non-inclined (or non-angled) top surface 112 serves a much wider purpose in the recliner base 106 than typical, prior recliner assemblies (which are limited to the specific inclined top surface).

Yet another exemplary benefit of the flat top surface 112 is that a wider seat size is achieved. For example, according to one configuration a seat width 114 increase of about 4 inches is achieved.

Referring to FIG. 3, the recliner base 106 further has a plurality of frame members, which include a front frame member 116, a right frame member 117, a left frame member 118, and a rear frame member 119. The frame members 116-119 are interconnected and mechanically attached to each other to provide a robust structure basis.

The recliner base 106 further has a top support 120 that forms the flat top surface 112 along, and aligned, with top edges 122 of the frame members 116-119. The front frame member 116 is generally rectangular and includes front attachment holes 124 to which additional components, such as a foot rest (not shown), is attachable. According to one example, the front attachment holes 124 include an array of four holes 124, arranged in a rectangular form of two rows and two columns. The rear frame member 119 is generally rectangular, providing primarily structural integrity for the recliner base 106.

Referring to FIG. 4, the right frame member 117 has a rectangular profile with a recessed surface 126 near a rear edge 128. The recessed surface 126 has a generally arcuate shape extending inward between the top edge 122 of the right frame member 117 and, partially, towards a lower edge 130. The left frame member 118 is similar to, but not necessarily identical with, the right frame member 117. For example, the left frame member 118 also has a recessed surface that matches the recessed surface 126 of the right frame member 117.

The right frame member 117 further includes frame attachment holes 132 to which a receiving connector 134 is attached. The receiving connector 134 has connector attachment holes 136 that match, respectively, the frame attachment holes 132.

Referring to FIGS. 5A and 5B, the receiving connector 134 has a mounting surface 138 on each side, with each mounting surface 138 having two connector attachment holes 136. The mounting surfaces 138 are in direct contact with the right frame member 117 when the receiving connector 134 is mounted to the right frame member 117. The receiving connector 134 further has a retaining side 140 that has a generally c-shaped profile relative to the mounting surfaces 138. The retaining side 140 creates a mounting space 142 in which a plug-in unit is easily inserted (as described below), without use of tools, for modular attachment to the recliner base 106.

Referring to FIGS. 6A and 6B, an insertion connector 144 has an insertion plate 145 that is connected to an attachment plate 147 via a connecting side 148. The insertion plate 145 is offset from and parallel to the attachment plate 147. The offset between the plates 145, 147 is based on a length dimension L of the connecting side 148. The attachment plate 147 has a plurality of attachment holes 149 that match respective attachment holes 149 of the armrest module 110. The attachment holes 149 are arranged in a generally rectangular array with two attachment holes 149 per row and column.

The insertion plate 145 has a bent end 150, which is angled away from the plane of the attachment plate 147. The bent end 150 is beneficial at least because it provides an enhanced secured engagement when a secured, modular attachment is achieved. Thus, for example, based on the force of gravity and further based on frictional tension between the bent end 150 and the retaining side 140 of the receiving connector 134 (as disclosed below), toolless and secure engagement is achieved when attaching a plug-in furniture unit to the recliner base 106.

Referring to FIGS. 7A and 7B, another receiving connector 134 is mounted to the left frame member 118 and receives within the mounting space 142 the insertion connector 144. The insertion plate 145 of the insertion connector 144 is mechanically fixed to the armrest module 110, which in this case is an exemplary plug-in unit. Thus, as a result of the effective and beneficial design of the receiving and insertion connectors 134, 144, the armrest module 110 is securely held in place with the recliner base 106. The secure, modular connection is based on a retaining force RF of the receiving connector 134 (including the added friction tension provided via the bent end 150) and on the force of gravity GF acting on the armrest module 110. However, disassembly is quick, easy, and toolless, requiring only a lifting force to remove the armrest module 110 from secure, but modular, connection with the recliner base 106.

Referring to FIGS. 8A and 8B, the armrest module 110 has a stepped design that is configured to enable resting of a user's head and arm with increased comfort. The armrest module 110 has an armrest member 151 configured to a height suitable for resting the user's arm when the user is in a seated position. The armrest module 110 further has a stepped member 152, which is lower than the armrest member 151 and which extends from a top vertical member 153. The stepped member 152 is configured to a height suitable for resting the user's head when lying down on the furniture assembly 100 (e.g., on a sofa).

The armrest module 110 further has a base horizontal member 154 that further extends inward relative to the stepped member 152. The base horizontal member 152 is generally parallel to the stepped member 152 and is generally perpendicular to a base vertical plate 155, which generally encloses an empty internal space 156 (shown in FIG. 8B). The empty internal space 156 is generally formed between a front side 157 and a rear side 158, which are generally interconnected via a plurality of structural members. The structural members include (among others) an upper rear member 159, an intermediate rear member 160, a lower rear member 161, the armrest member 151 (all of which are only shown in FIG. 8B), the stepped member 152, and the base horizontal member 154.

The structural design and configuration of the armrest module 110 is beneficial for several reasons. For example, the armrest module 110 is beneficial because it combines an optimal and efficient balance between structural integrity and low weight. The low weight is further achieved, for example, having a through empty space 162 between the base horizontal member and the stepped member 152. In another example, the armrest module 110 is beneficial because it facilitates easy, convenient, and toolless modular combination with other furniture components.

Referring to FIG. 9, the backrest module 108 forms a continuous and straight surface 163 with the recliner base 106 in a non-reclined position. More specifically, a back surface 164 of the backrest module 108 is aligned in a straight, continuous form with a rear surface 165 of the recliner base 106. The continuous surface 163 is beneficial at least because the lack of an offset (as typically found in prior recliners) between the two surfaces 164, 165 allows placement of the combined furniture (of the recliner base 106 and the backrest module 108) close to and/or in direct contact with a room wall 166 in which the furniture is located.

Referring to FIGS. 10 and 11, the recessed surface 126 provides a movement guide for the backrest module 108 when moving from a non-reclined position (shown in FIG. 10) to a reclined position (shown in FIG. 11). As the backrest module 108 retracts in a clockwise direction, a bottom surface 167 of the backrest module 108 is in direct contact with and moves along the recessed surface 126 towards in a front direction FD. The interaction between the recessed surface 126 and the bottom surface 167 prevents any portion of the backrest module 108 to move in a rear direction RD towards the room wall 166.

Referring to FIG. 12, the movement of the backrest module 108 along the recess surfaces 126 of the right and left frame members 117, 118 is further facilitated by a transverse gap 168 that extends between the recessed surfaces 126. The transverse gap 168 allows unobstructed movement of the backrest module 108 relative to the recliner base 106.

Referring to FIG. 13, the backrest module 108 has a right backrest section 169 structurally connected with a left backrest section 170 via a plurality of connecting members. Each of the backrest sections 169, 170 has two parallel plates, which include an end plate 171 that is offset from and separated by a gap from an inner plate 173.

The connecting members include a top connecting plate 175, a front-top connecting beam 177, a front-bottom connecting beam 179, and a rear-bottom connecting beam 181. Each pair of parallel plates 171, 173 is structurally inter-connected via a front connecting beam 183. The end plates 171 are connected via the front-top connecting beam 181. The inner plates 173 are connected via the front-bottom and rear-bottom connecting beams 179, 181.

The backrest module 108 further includes a headrest frame 184 that is attached to the top connecting plate 175. More specifically, the headrest frame 184 is coupled with two headrest attachments 186. The headrest frame 184 provides structural support for additional furniture components that facilitates comfort and support for the head of a user.

Referring to FIG. 14, the backrest module 108 further has a pair of rear connecting beams 185 and a rear-top connecting beam 187. Each rear connecting beam 185 further reinforces (in addition to the respective front connecting beam 183) the structural integrity between a respective pair of parallel plates 171, 173. The rear-top connecting beam 187 further reinforces (in addition to the front-top connecting beam 117) the structural integrity between the end plates 171.

Referring to FIG. 15, the inner plate 173 has a bottom inclined surface 189 that is continuous with a curved surface 191. The curved surface 191 is continuous with a diagonal surface 193. The general periphery of the inner plate 173 includes a top surface 195 and a rear surface 197. The bottom inclined surface is non-parallel relative to the top surface 195.

Referring to FIG. 16, the end plate 171 has a different geometric profile than the inner plate 173. The end plate 17 has a bottom surface 199 that has a relatively less-inclined angle than the bottom inclined surface 189 of the inner plate 173. The bottom surface 199 of the end plate 171 is continuous with a curved surface 201, which is relatively less curved than the curved surface 191 of the inner plate 173. The curved surface 201 of the end plate 171 is continuous with a diagonal surface 203 of the end plate 171, which in turn is continuous with a top surface 205 of the end plate 171. The end plate 171 further includes a rear surface 207 that is continuous with the bottom surface 199. The geometric profile of the end plate 171 is designed to guide the backrest module 108 along the respective recess surface 126.

Referring to FIG. 17, the recliner base 106 has additional components that render it structurally sound, with low weight and modularity capability. The top support 120 consists of two sandwiched frame layers, which include a top frame layer 210 and a bottom frame layer 212. The frame layers 210, 212 have a large internal space 214 to reduce unnecessary weight, but still provide structural integrity to the recliner base 106.

The recliner base 106 further includes a left frame structure 216 and a right frame structure 218. Each frame structure 216, 218 has a top member 220 connected to a bottom member 222 via an internal member 224. Externally, the frame structures 216, 218 are directly and respectively attached to the right and left frame members 117, 118. A pair of transverse members 226, 228 further structurally attach the internal members 224 to each other, increasing overall strength and structural integrity.

Referring to FIG. 18, a pivotable connector 301 is provided. The pivotal connector 301 allows for toolless and secure engagement when attaching or securing two modular adjacent components (e.g., the modular recliner 102 of FIG. 1, the modular universal base 104 of FIG. 1, etc.). The pivotable connector 301 includes a pair of pivotable plates (i.e., a first pivotable plate 302a and a second pivotable plate 302b) that securely latch together to secure the two modular adjacent components. Each of the first and second pivotable plates 302a, 302b is illustrated in an elevated position.

In the example of FIG. 18, the modular universal base 104 is adjacent to the recliner base 106. The modular universal base 104 is to be secured to the recliner base 106. The pivotable connector 301 includes vertical mounting plates (i.e., a first vertical mounting plate 304a and a second vertical mounting plate 304b) which are permanently fixed to the interior surfaces of the frames of the modular adjacent components (i.e., the left frame member 118 of the recliner base 106 and a right outer frame member 303 of the modular universal base 104). The first and second pivotable plates 302a, 302b are hingeably connected to the first and second vertical mounting plates 304a, 304b, respectively. In some implementations, a butt hinge provides the hinge connection between a pivotable plate (e.g., the first pivotable plate 302a) and a vertical mounting plate (e.g., the first vertical mounting plate 304a). The first and second pivotable plates 302a, 302b pivot or rotate about their respective hinge connections relative to the first and second vertical mounting plates 304a, 304b.

In some implementations, each of the first and second pivotable plates 302a, 302b has identical dimensions (i.e., thickness, width, and height are equal). In some implementations, each of the first and second pivotable plates 302a, 302b has a rectangular or square shape. In some implementations, the rectangular or square shape includes rounded corners.

Referring to FIGS. 19A and 19B, the second pivotable plate 302b is positioned in a coupling position while the first pivotable plate 302a remains in the elevated position. In some implementations, when in the coupling position, the second pivotable plate 302b extends across a top edge of the right outer frame member 303 to rest atop a top edge of the left frame member 118. In some implementations, the second pivotable plate 302b is provided at an angle such that the second pivotable plate 302b rests atop the top edge of the left frame member 118 but does not make contact with the top edge of the right outer frame member 303. In the coupling position, the separation between the second pivotable plate 302b and the top edge of the right outer frame member 303 is adjustable based on the position of the hinge connection between the second pivotable plate 302b and the second vertical pivotable plate 304b.

The first and second pivotable plates 302a, 302b include one or more coupling holes 306a, 306b, respectively. The first and second pivotable plates 302a, 302b further include one or more protrusions 308a, 308b, respectively. The one or more protrusions 308a are configured to couple with the one or more coupling holes 306b. Similarly, the one or more protrusions 308b are configured to couple with the one or more coupling holes 306a. In some implementations, as provided in FIGS. 18 and 19A, each of the first and second pivotable plates 302a, 302b includes two protrusions 308a, 308b, respectively, and two coupling holes 306a, 306b, respectively. In some implementations, the two protrusions 308a, 308b can be provided along a long edge of the first and second pivotable plates 302a, 302b, respectively. In some implementations, the two protrusions 308a, 308b can be provided at corners of the first and second pivotable plates 302a, 302b, respectively.

Similarly, the two coupling holes 306a, 306b can be provided along a long edge of the first and second pivotable plates 302a, 302b, respectively, and/or at corners of the first and second pivotable plates 302a, 302b, respectively. Locations of the two protrusions 308a, 308b and the two coupling holes 306a, 306b are provided in one configuration in FIGS. 18, 19A, and 19B only as an example. In some implementations, the two coupling holes 306a, 306b are provided closer to the hinge connections to facilitate the two coupling holes 306a, 306b clearing a height of the two protrusions 308a, 308b. For example, in the coupling position, having the two protrusions 308b resting on the top edge of the left frame member 118 and having the second pivotable plate 302b at an angle (FIG. 19B) facilitates the two coupling holes 306a clearing a top of the two protrusions 308b to engage the two protrusions 308b.

Referring to FIGS. 20A and 20B, both the second pivotable plate 302b and the first pivotable plate 302a are positioned in the coupling position, with both the first and second pivotable plates 302a, 302b partially overlapping each other. Although in FIGS. 20A and 20B, the second pivotable plate 302b is underneath the first pivotable plate 302a, in other configurations, the first pivotable plate 302a can be placed in the coupling position before the second pivotable plate 302b such that the first pivotable plate 302a is underneath the second pivotable plate 302b. This design of the first and the second pivotable plates 302a, 302b allow flexibility in coupling the modular adjacent components. The two coupling holes 306a are positioned to match the two protrusions 308b when in the coupling position. Similarly, the two coupling holes 306b are positioned to match the two protrusions 308a when in the coupling position. In the configuration of FIGS. 18-20B, due to the positioning of the protrusions and coupling holes, either the two protrusions 308b are engaged by the coupling holes 306a or the two protrusions 308a are engaged by the coupling holes 306b, but not both. Other configurations that rearrange the protrusions and coupling holes can result in both protrusions 308a, 308b always engaged in both coupling holes 306b, 306a.

In the configuration of FIGS. 18-20B, the vertical mounting plates 304a, 304b are attached to the interior surfaces of the frames of the modular adjacent components. In some implementations, one or more of these vertical mounting plates 304a, 304b can be attached to an exterior of the frame of the modular adjacent components. Although the positioning of the coupling holes and protrusions are similar for both the first and second pivotable plates 302a, 302b, in some implementations, one of the pivotable plates can include only protrusions while the other one of the pivotable plates can include only coupling holes for engaging the protrusions. In such a configuration, aspect ratio of the pivotable plates can differ such that the pivotable plates having only protrusions have a larger surface area compared to pivotable plates having only holes.

Referring to FIG. 21A, a snapping connector piece 310 for securing modular adjacent components is provided, according to certain aspects of the present disclosure. The snapping connector piece 310 is coupled with modified receiving connectors 311 for securing the modular adjacent components. Modified receiving connectors 311 are similar to the receiving connector 134 of FIGS. 5A and 5B. The modified receiving connectors 311 are coupled to the inner surfaces of the frames of the modular adjacent components (e.g., the left frame member 118 of the recliner base 106 and the right outer frame member 303 of the modular universal base 104). The snapping connector piece 310 couples to both of the modified receiving connectors as provided in FIG. 21B to secure the modular adjacent components. The modified receiving connector 311 includes recessed portions 312 for receiving pins 310 of the snapping connector piece 310.

The snapping connector piece 310 has a central plate 314 with the pins 313 coupled to the central plate 314. In some implementations, the pins 313 are bent or hook-shaped to conform to a shape of the recess 312. The conformity allows for latching to the corresponding modified receiving connector 311. To install the snapping connector 310, the central plate 314 can be pressed downward so that one pair of pins 313 latch to the modified receiving connector 311 on the left frame member 118 while the other pair of pins 313 latch to the modified receiving connector 311 on the right outer frame member 303. When installation is complete, each pair of pins 313 is lodged into the front and back recesses 312 of the corresponding modified receiving connector 311. Tension provided by the rigid structure of the snapping connector piece 310 pinch each pair of ins together to prevent removal of the pins 313 from the recesses 312.

Referring to FIGS. 22 and 23, a Z-Shaped connector 320 and an L-Shaped connector 322 is provided, according to certain aspects of the present disclosure. The Z-Shaped connector 320 includes three portions (i.e., a first portion 321, a second portion 323, and a third portion 324). The first portion 321 and the second portion 323 are connected to each other at a first angle 329. The second portion 323 is connected to the third portion 324 at a second angle 332. The first portion 321 can be attached to a component of the modular furniture assembly 100 (e.g., attached to the armrest module 110 of FIG. 2 via a mounting panel 330 having mounting holes 327). The second portion 323 and the third portion 324 are inserted into a receptacle or a cavity provided in the modular universal base 104. This is shown in FIGS. 24A and 24B. The Z-Shaped connector 320 is malleable and can be locked in the receptacle or cavity using the L-Shaped connector 322. The L-Shaped connector 322 includes a first portion 326 and a second portion 325 provided at an angle 331. The first portion 326 is insertable into the receptacle to lock the Z-Shaped connector 320 in place.

Referring to FIG. 25, a headrest 350 is provided. The headrest 350 includes a cushioned portion 351 and one or more insertion poles 352a, 352b. Each of the insertion poles 352a, 352b includes adjustable settings 354a, 354b. The adjustable settings 354a, 354b include smaller diameter portions separated by larger diameter portions of the insertion poles 352a, 352b. The headrest 350 is insertable in a backrest as provided in FIG. 26. A user can push the headrest 350 into the backrest or pull the headrest 350 from the backrest to adjust a height of the cushioned portion 351. The adjustable settings 354a, 354b lock in the smaller diameter portions.

Referring to FIG. 27, a U-Shaped connector can be provided on surface of a first modular component.
