Background Technology
[0002] With the development of society, people's material living standards have been gradually improved. Therefore, as the sofa became an important part of furniture in daily life, people put forward higher requirements for it.
[0003] The traditional sofa usually uses a lot of wood material, especially the supporting frame of the conventional sofa, usually made of a plurality of boards. Multiple wooden boards often enclose to form a wooden supporting frame with an internal space, and the main structure of the sofa is fixedly installed in the internal space formed by the wooden supporting frame. However, when assembling the sofa, a large number of professionals are required to use nail guns to connect and secure multiple wooden boards to form a complete wooden support frame, which is then mounted with the main structure of the sofa. As a result, the assembly process is cumbersome and laborious, resulting in lower production efficiency, which in turn increases the required labor costs. Moreover, due to the fact that multiple wooden boards constituting the wooden support frame may have different shapes, it is necessary to complete the processing of each type of board based on separate drawing programming and layout when producing the boards. This reduces the processing efficiency of the board and increases the processing cost. In addition, for modular or sectional sofas, it is necessary to fix the two wooden support frames on an adjoining sofa assembly together, which typically must also be done by a professional and the installation process is cumbersome.
[0004] Therefore, traditional sofas need to be improved, particularly the wooden support frame, in order to simplify the structure of parts for supporting the sofa on the floor, thereby simplifying the assembly process of the sofa, improving the aesthetics of the sofa, and improving the production efficiency and reducing the production costs.

[0041] Figures 1 and 2 shows a perspective view of a sofa assembly 100 according to an exemplary embodiment of the present invention. The sofa assembly 100 includes a main structure 1, a first foot stand 2, a second foot stand 3, and a rear panel 4.
[0042] The first foot stand 2 and the second foot stand 3 can be selected from one or more metal parts, blow molded parts, injection molded parts, extruded molded parts and wood molded parts. When the first foot stand 2 and the second foot stand 3 are metal parts, they may be made of one or more metal materials of iron, aluminum, and alloys thereof through a stamping process. When the first foot stand 2 and the second foot stand 3 are non-metal parts, they can be made of one or more non-metal materials of thermoplastic materials such as polyethylene, polyvinyl chloride, polypropylene, polyester, and the like through blow-molded, injection molding, extrusion molding or wood plastic processes.
[0043] For the convenience of describing exemplary embodiments of the present invention, the length direction, width direction, and height direction of the sofa assembly 100 are now labeled as D1, D2, and D3, respectively. Moreover, the length direction of the main structure 1, the first foot stand 2, and the second foot stand 3 is parallel to the length direction D1 of the sofa assembly 100.The width direction of the main structure 1 is parallel to the width direction D2 of the sofa assembly 100, and the height direction of the main structure 1, the first foot stand 2, and the second foot stand 3 is parallel to the height direction D3 of the sofa assembly 100.
[0044] As shown, the main structure 1 has a substantially rectangular shape when viewed from above of the sofa assembly 100. The main structure 1 has a front F and a rear B along the length direction D1. The first foot stand 2 and the second foot stand 3 are respectively arranged on both sides of the main structure 1 along the width direction D2 and connected to the main structure 1. The rear panel 4 is positioned between the first foot stand 2 and the second foot stand 3, at the rear B of the main structure 1, and is connected to the rear end of the first foot stand 2 and the rear end of the second foot stand 3, respectively. The front end of the first foot stand 2 and the front end of the second foot stand 3 are both close to the forward F of the main structure 1, while the rear end of the first foot stand 2 and the rear end of the second foot stand 3 are both close to the backward B of the main structure 1. The forward, backward, front end and rear end are all referred to as the orientation perceived by the user when sitting on the sofa assembly 100, and the same applies to the left side and right side mentioned in this manual.
[0045] Preferably, the first foot stand 2 and the second foot stand 3 may be integrally connected to the main structure 1 by riveting.
[0046] Compared with the traditional wooden support frame, the sofa assembly 100 provided by the present invention has a smaller number of components, and the structure of the components is simpler, so the assembly process is simplified, and the automatic assembly of the manipulator can be realized or the assembly can be completed without professionals. In addition, the first foot stand 2 and the second foot stand 3 can be industrialized and automatically produced through stamping, blow-molded, injection molding, extrusion molding or wood-plastic molds, which avoids the traditional wood board processing, and can also improve the aesthetics of the product and ensure a high-quality rate. Therefore, the cost is reduced, and the production efficiency and product quality are improved.
[0047] Meanwhile, the first foot stand 2 and the second foot stand 3 are connected with the main structure 1 by riveting, so that they can be used directly without the need for workers to assemble them, thus further improving production efficiency, and reducing labor costs.
[0048] Referring to Figures 3 and 4, the first foot stand 2 has a first bracket 21 and two first support legs 22a, 22b. The first bracket 21 and the two first support legs 22a, 22b are preferably integrally formed using a metal part. The first bracket 21 extends along the length direction D1. The two first support legs 22a, 22b are respectively located at the front end and the rear end of the first bracket 21 along the length direction D1. Along the height direction D3, the upper edge of the first bracket 21 and the upper edges of the two first support legs 22a, 22b are aligned, and the heights of the two first support legs 22a, 22b are equal to and greater than the height of the first bracket 21. Therefore, when the first foot stand 2 is placed vertically on the ground, the two first support legs 22a, 22b first contact with the ground, so that the first bracket 21 can be suspended above the ground.
[0049] The first foot stand 2 may also have at least one first fixing portion 23. The first fixing portion 23 is configured to be able to fix the first foot stand 2 to the main structure 1. In an exemplary embodiment of the present invention, the first foot stand 2 has two first fixing portions 23 provided on the first bracket 21 at intervals along the length direction D1. The first fixing portion 23 is recessed from the outer side of the first foot stand 2 to the inner side thereof in the width direction D2, and a recess is formed on the outer side while a protrusion is formed on the inner side. The outer side of the first foot stand 2 refers to a side of the first foot stand 2 away from the main structure 1 along the width direction D2. The inner side of the first foot stand 2 refers to a side of the first foot stand 2 near the main structure 1 along the width direction D2. Preferably, the outline of the first fixing portion 23 may be rectangular.
[0050] As shown in the figure, the first upper fixing portion 23a is adjoined to the first support leg 22a and the first lower fixing portion 23b is adjoined to the first support leg 22b. Among them, the first upper fixing portion 23a intersects the upper edge 24a of the first foot stand 2, thus forming an opening at the upper edge 24a. Similarly, the first lower fixing portion 23b intersects the lower edge 24b of the first foot stand 2, and thus an opening is also formed at the lower edge 24b. The first upper fixing portion 23a and the first lower fixing portion 23b may also be provided with at least one through hole for fixing them to the main structure 1, respectively.
[0051] The first foot stand 2 may also be provided with at least one reinforcing rib. The reinforcing rib is recessed from the outer side of the first foot stand 2 to the inner side thereof in the width direction D2, and a recess is formed on the outer side while a protrusion is formed on the inner side. Also, the reinforcing rib may extend along the length direction D1, along the height direction D3, or along a direction at an angle to the length direction D1 over at least a portion of the first foot stand 2. The shape of the reinforcing rib may be rectilinear shape, bent shape, curved shape, triangular, rectangular, polygonal, or other shapes.
[0052] As shown, the first foot stand 2 has reinforcing ribs 25a, 25b and 25c. Among them, the reinforcing rib 25a is located at the junction of the first bracket 21 and the first support leg 22a, and extends from the first support leg 22a to the first bracket 21 at an angle to the length direction D1. The reinforcing rib 25b extends along the length direction D1 over a portion of the first bracket 21. Preferably, the reinforcing rib 25b extends from a position near the first upper fixing portion 23a to near the first support leg 22b. Further, the reinforcing rib 25b is located on the side of the first lower fixing portion 23b near the upper edge 24a. And the reinforcing rib 25c is located at the junction of the first bracket 21 and the first support leg 22b, and extends from the first support leg 22b to the first bracket 21 in a direction at an angle to the length direction D1.
[0053] Preferably, at least one of the two first support legs 22a, 22b may be provided with a reinforcing rib.
[0054] In addition, the first foot stand 2 may also have at least one first connection portion 26 detachably connected to an adjoining foot stand. For example, as shown in the figure, the first foot stand 2 has two first connection portions 26 arranged at intervals along the length direction D1. Among them, one of the first connection portions 26 is located at the first support leg 22a, and the other first connection portion 26 is located at the first support leg 22b. The first connection portion 26 extends from the outer side to the inner side of the first foot stand 2, and also intersects with the upper edge 24a of the first foot stand 2 to form an opening at the upper edge 24a, so that the first connection portion 26 forms an opening through the first foot stand 2 in the width direction D2.
[0055] As an exemplary embodiment of the present invention, the first connection portion 26 may have a slide-in section 261 and a locking section 262. The slide-in section 261 extends along the direction at an angle relative to the height direction D3, from the opening at the upper edge 24a towards the interior of the first support leg 22a or first support leg 22b, and, after extending a distance, it continues to extend along the height direction D3, thereby forming a locking section 262 located below the slide-in section 261. The slide-in section 261 and the locking section 262 communicate with each other. In addition, the width of the opening formed by the slide-in section 261 can be larger than the width of the opening formed by the locking section 262, so that the part of the adjoining foot frame matched with the first connection portion 26 can easily enter the slide-in section 261.
[0056] Preferably, the first connection portion 26 may also have a stopper portion 263. The stopper portion 263 may be set in the transition region between the slide-in section 261 and the locking section 262. As shown, the stopper portion 263 may be a protrusion extending along the length direction D1 and configured to reduce the opening width of the transition region between the slide-in section 261 and the locking section 262.
[0057] Referring now to Figures 5 to 7, the second foot stand 3 has a second bracket 31 and two second support legs 32a, 32b.

The two second support legs 32a, 32b are respectively located at the front and rear end of the second bracket 31 along the length direction D1. In the height direction D3, the upper edge of the second bracket 31 and the upper edges of the two second support legs 32a, 32b are aligned, and the heights of the two second support legs 32a, 32b are equal to and greater than the height of the second bracket 31. Therefore, when the second foot stand 3 is placed vertically on the ground, the two second support legs 32a, 32b first contact the ground so that the second bracket 31 can be suspended above the ground.
[0058] Therefore, when the completed sofa assembly 100 is vertically placed on the ground, the two first support legs 22a, 22b of the first foot stand 2 and the two second support legs 32a, 32b of the second foot stand 3 will first contact the ground surface so that the main structure 1 can be suspended above it.
[0059] Continuing to refer to Figures 5-7, the second foot stand 3 may further have at least one second fixing portion 33. The second fixing portion 33 is configured to be able to fix the second foot stand 3 to the main structure 1. In an exemplary embodiment of the present invention, the second foot stand 3 has two second fixing portions 33 provided on the second bracket 31 at intervals along the length direction D1. The second fixing portion 33 is recessed along the width direction D2 from the outer side to the inner side of the second foot stand 3, and a recess is formed on the outer side while a protrusion is formed on the inner side. The outer side of the second foot stand 3 refers to a side of the second foot stand 3 away from the main structure 1 along the width direction D2. The inner side of the second foot stand 3 refers to a side of the second foot stand 3 that is close to the main structure 1 along the width direction D2. Preferably, the outline of the second fixing portion 33 may be rectangular.
[0060] Furthermore, the two second fixing portions 33 are respectively the second upper fixing portion 33a near the second support leg 32a and a second lower fixing portion 33b near the second support leg 32b. Wherein the second upper fixing portion 33a intersects with the upper edge 34a of the second foot stand 3, thus forming an opening at the upper edge 34a. Similarly, the second lower fixing portion 33b intersects the lower edge 34b of the second foot stand 3, and thus, an opening is also formed at the lower edge 34b. The second upper fixing portion 33a and the second lower fixing portion 33b may also be provided with at least one through hole for fixing them to the main structure 1, respectively.
[0061] Preferably, the second fixing portion 33 may be positioned opposite to the first fixing portion 23 in the width direction D2.
[0062] The second foot stand 3 may also be provided with at least one reinforcing rib. The reinforcing rib is recessed along the width direction D2 from the outer side to the inner side of the second foot stand 3, and a recess is formed on the outer side while a protrusion is formed on the inner side. Also, the reinforcing rib may extend along the length direction D1, along the height direction D3, or along a direction at an angle to the length direction D1 over at least a portion of the second foot stand 3. The shape of the reinforcing rib may be a rectilinear shape, bent shape, curved shape, triangular, rectangular, polygonal, or other shapes.
[0063] As shown, the second foot stand 3 has reinforcing rib 35a, 35b and 35c. Among them, the reinforcing rib 35a is located at the junction of the second bracket 31 and the second support leg 32a, and extends from the second support leg 32a to the second bracket 31 in a direction at an angle to the length direction D1.

The reinforcing rib 35c is located at the junction of the second bracket 31 and the second support leg 32b and extends substantially along the length direction D1 from the second support leg 32b to the second bracket 31.
[0064] Preferably, at least one of the two second support legs 32a and 32b may be provided with a reinforcing rib.
[0065] As shown in Figures 2 and 7, the second foot stand 3 may further have at least one second connection portion 36 disposed opposite the first connection portion 26 along the width direction D2. The first connection portion 26 and the second connection portion 36 may be configured to match in number and be detachably connectable.
[0066] For example, the second foot stand 3 may have two second connection portions 36 arranged at intervals along the length direction D1. Among them, one second connection portion 36, is located at the second support leg 32a, and the other second connection portion 36 is located at the second support leg 32b.
[0067] As shown in Figure 8, the second connection portion 36 has a head portion 361, a first rod body 362, and a second rod body 363 arranged in sequence along its own length direction. Among them, the head portion 361, the first rod body 362, and the second rod body 363 may all have a cylindrical shape. Further, the diameter of the head 361 is larger than that of the first rod body 362. The diameter of the first rod body 362 may also be larger than that of the second rod body 363, thereby forming a stepped portion 364 between the first rod body 362 and the second rod body 363. The second rod body 363 may be further provided with an external thread (not shown) to cooperate with the fixing hole 39 of the second foot stand 3, to mount the second connection portion 36 to the second foot stand 3. Preferably, the diameter of the head portion 361 of the second connection portion 36 is larger than the opening width of the locking section 262 of the first connection portion 26 to prevent the head portion 361 from passing through the locking section 262 along the width direction D2.
[0068] To facilitate understanding of the detachable connection between the first connection portion 26 and the second connection portion 36, a process of connecting the second connection portion 36 to the first connection portion 26 and a process of removing the second connection portion 36 from the first connection portion 26 will be described exemplarily below.
[0069] When connecting the second connection portion 36 to the first connection portion 26, the second connection portion 36 is placed above the first connection portion 26. The first rod body 362 of the second connection portion 36 is aligned with the opening of the first connection portion 26, and the head portion 361 of the second connection portion 36 is located on the inner side of the first foot stand 2; then, the first rod body 362 enters the slide-in section 261 through the opening and slides obliquely downward along the slide-in section 261. Finally, the first rod body 362 is slid into the locking section 262, thereby completing the connection between the second connection portion 36 and the first connection portion 26.
[0070] The process of removing the second connection portion 36 from the first connection portion 26 is opposite to the above-described connection process and will not be described again.
[0071] By setting detachable the first connection portion 26 and the second connection portion 36 on the first foot stand 2 and the second foot stand 3 at both sides of the sofa assembly 100, the quick connection and disassembly between two adjoining sofa assemblies can be realized. Thus, the connection between two adjoining sofa assemblies can be accomplished easily by sliding the second connection portion 36 into the first connection portion 26. Furthermore, it can simplify the assembly process of the sofa, improve production efficiency, and reduce costs.
[0072] Moreover, when the second connection portion 36 has been connected in place, the stopper portion 263 in the first connection portion 26 may also prevent the second connection portion 36 from being accidentally separated from the first connection portion 26, or restrict the upward movement of second connection portion 36 along the height direction D3.
[0073] Meanwhile, when the first connection portion 26 and the second connection portion 36 are connected in place, the head portion 361 of the second connection portion 36 is located at the inner side of the first foot stand 2, and since the diameter of the head portion 361 is larger than the size of the locking section 262, the head portion 361 can also restrict the movement of the second connection portion 36 relative to the first connection portion 26 along the width direction D2. Therefore, a firm connection between two adjoining sofa assemblies can be ensured. In addition, the first foot stand 2 may further have at least one fixing hole 28, and the second foot stand 3 may further have at least one fixing hole 38 arranged opposite to at least one fixing hole 28 along the width direction D2. The fixing holes 28, 38 are used to connect the first foot stand 2 and the second foot stand 3, respectively, to the main structure 1. Preferably, the first foot stand 2 and the second foot stand 3 are connected to the anti-torsion tube of the main structure 1 through the fixing holes 28, 38, respectively, to prevent the sofa assembly 100 from being twisted.

Both ends of the rear panel 4 in the width direction D2 are connected to the pair of rear panels fixing component 5, 5';
[0075] As shown in Figures 9 and 10, the rear panel fixing component 5 has an intermediate portion 51, and a first bending section 52 and a second bending section 53 respectively located at both ends of the intermediate portion. The intermediate portion 51 is generally in the shape of "L". Specifically, the intermediate portion 51 has a horizontal section 511 and an inclined section 512. The horizontal section 511 may extend in the length direction D1 or in a direction at an angle to the length direction D1, and the inclined section 512 may extend in the height direction D3 or in a direction at an angle to the height direction D3. Wherein the inclined section 512 is located above or obliquely above the horizontal section 511. And one end of the inclined section 512 is connected to one end of the horizontal section 511 to form a shape of an "L". The first bending section 52 is located at the other end of the horizontal section 511 and extends a distance along the width direction D2 from the other end. The second bending section 53 is located at the other end of the inclined section 512 and extends a distance in the same direction as the first bending section 52 along the width direction D2 from the other end. In addition, the angle between the horizontal section 511 and the inclined section 512 of the intermediate portion 51 may be equal to or greater than 90 degrees. As shown in the figure, as an example, the horizontal section 511 extends along a direction that forms an acute angle with the length direction D1, and the inclined section 512 extends along a direction that forms an obtuse angle with the length direction D1, while the angle between the horizontal section 511 and the inclined section 512 is greater than 90 degrees.
[0076] The intermediate portion 51 is further provided with at least one foot mounting hole 513 for connecting the rear panel fixing component 5 to the first foot stand 2.
