Referring to fig. 1 and 2, an embodiment of the sofa frame of the present application is provided, which includes a support frame 101 and an insert 102, the support frame 101 includes three main beams 103 arranged in parallel in a transverse direction, a cushion support area is defined between the main beam 103 located at the front side and the main beam 103 located in the middle, a cushion support area is defined between the main beam 103 located at the rear side and the main beam 103 located in the middle, and a plurality of connection beams 104 are further included, the plurality of connection beams 104 connect the two main beams 103 located at the rear side and the middle, the insert 102 is connected with the connection beams 104 and protrudes upward to the top of the cushion support area, and the insert 102 can be inserted into a cushion of a sofa to connect the cushion to the cushion support area.

The sofa frame described above provides a very convenient mounting base for a worker or user to quickly assemble other components of the sofa, including the seat cushion, back cushion or armrests.

It should be noted that, in order to achieve assembly, the sofa component to be assembled, such as a cushion, needs to have a connection structure that is matched with the plug connector 102, for example, the sofa component needs to have a notch for the plug connector 102 of the plug connector 102 to insert, the notch is usually located at the bottom of the sofa component, and the interior of the sofa component is provided with an inner cavity for accommodating the plug connector 102.

Specifically, when the sofa assembly is assembled, the socket at the bottom of the sofa assembly is aligned with the connector 102, so that the sofa assembly can be pushed to be sleeved into the connector 102 until the bottom plane of the sofa assembly contacts the top surface of the sofa frame, and the connector 102 is integrally sleeved in the inner cavity of the sofa assembly, thereby completing the assembly of the sofa assembly. Correspondingly, when the assembled sofa component needs to be taken down from the sofa frame, for example, to be replaced, at the moment, the sofa component can be taken down only by pushing the corresponding sofa component upwards. In addition, the sofa frame structure composed of the main beam 103 and the connecting beam 104 is stable, and the safety can be improved.

Therefore, the assembly efficiency can be greatly improved no matter the sofa is assembled in a factory or assembled at a user position, and meanwhile, in a subsequent use link, a user can replace the sofa component at any time, so that the personalized requirements of the sofa component can be met. In addition, when the sofa assembly is damaged or old, only the parts need to be discarded, and the sofa frame can be used for a long time without causing adverse effects on the environment, so that the resources are effectively saved, and the sofa frame is environment-friendly.

Different sofa assemblies may vary depending on different needs and uses, for example, in some cases, the sofa may require only cushions and no arms, in which case, the corresponding connectors 102 for attaching cushions may need to be provided on the rear side of the sofa frame. In the present embodiment, a sofa having a pair of armrests respectively located on the left and right sides of a sofa frame and two cushions is described as an example.

Referring to fig. 1 and 2, in one or more embodiments, in order to provide more structural stability and to securely position and connect the pads, the connectors 102 are bar members having an inverted U shape, the number of the connecting beams 104 is 2 times the number of the connectors 102, and one connecting beam 104 is connected to each end of each connector 102. That is, one end of each of the plug-in units 102 having the inverted U-shaped bar member is connected and supported by a single connection beam 104. Thus, the whole U-shaped part of the plug connector 102 is inserted into the corresponding notch and inner cavity of the sofa component as an insertion end, the whole width of the plug connector 102 can be matched with the size of the sofa component to be assembled by controlling the width of the U-shaped part, and the sofa component has enough rigidity and strength, can resist deformation and ensures that the back cushion can be accurately positioned and supported. Further, as shown in fig. 2, the plug member 102 in the form of an inverted U-shaped bar member is composed of a cross bar 105, a vertical bar 106, a connecting bend 107, and the like. Of course, the bar in the shape of an inverted U may be a one-piece bar, for example, formed by bending a metal tube.

Of course, the plug 102 may be in other forms as long as it can connect the sofa component, for example, the plug 102 may be a columnar member capable of matching with a hole provided at the bottom of the sofa component, so as to position and connect the sofa component.

It should be noted that the number of the connectors 102 may or may not be the same as the number of sofa components to be assembled. For example, in one or more embodiments, a sofa assembly may be configured with multiple plug connectors 102 for connection.

In one or more embodiments, the plug 102 may also cooperate with a locking structure or a separate locking structure provided thereon to lock the cushion in place, such as a snap provided on the plug 102.

In some of these embodiments, the connecting beam 104 is lockably slidably connected to the main beam 103. Thus, the connecting beam 104 can be moved in the length direction of the main beam 103 to adjust the position thereof, thereby changing the position of the connector 102 connected thereto, so as to correctly mount the cushion or adjust the position of the cushion according to the user's needs.

More specifically, the first runner 108 may be on the side of the main beam 103 facing the bolster support area, which may facilitate space savings for arranging the various components. More specifically, the first connecting member 109 includes a connecting piece 110, a first protrusion 111 capable of extending into the first sliding groove 108, and a first screw 112, and the connecting piece 110 and the first protrusion 111 can be connected by the first screw 112 through threads. Thus, when the sofa frame is installed, the first connecting member 109 is positioned at the right position, and then the first connecting member 109 is locked in the first sliding groove 108 of the main beam 103 by tightening the first screw rod 112, so that the connecting beam 104 is fixed. If the position of the first connecting member 109 needs to be adjusted, only the first screw rod 112 needs to be loosened.

In addition, because the main beam 103 adopts the section bar structure, when in production, the sofa with different sizes, such as different lengths and widths, can be produced by cutting the main beam 103 in factories, the design and manufacturing cost can be effectively reduced, and meanwhile, the user can also adjust the size of the sofa frame by cutting the main beam 103 so as to meet the actual requirement.

In one or more embodiments, the plug 102 is lockably slidably connected to the bridge 104. Thus, the connector 102 can be moved along the length of the connecting beam 104 to adjust the position of the cushion for proper installation or to adjust the position of the cushion as desired by the user.

The number of the second connectors 114 corresponds to the number of the ends of the connector 102, for example, in the case of the aforementioned inverted U-shaped rod-shaped connector 102 having two ends for connection, 2 second connectors 114 are required for this type of connector 102. More specifically, the second runner 113 may be at the side of the connecting beam 104 toward the other connecting beam 104, which may save space for arranging the respective components. More specifically, the second connecting member 114 includes a connecting portion 115, a second protrusion 116 extending into the second sliding groove 113 is provided on a side surface of the connecting portion 115, the second protrusion 116 is capable of being slidably engaged with an inner wall of the second sliding groove 113, a screw hole penetrating the entire connecting portion 115 and the second protrusion 116 is further provided on a side surface of the connecting portion 115, and the second screw 117 locks the second connecting member 114 by being engaged with a screw thread of the screw hole. Thus, when the sofa frame is installed, the second connecting member 114 is positioned at the correct position, and then the second connecting member 114 is locked in the second sliding groove 113 of the connecting beam 104 by a fastener such as a screw, so that the second connecting member 114 is fixed. If the position of the second connecting member 114 needs to be adjusted, only the second screw 117 needs to be loosened.

Therefore, on one hand, the connection of the plug-in connector 102 is convenient to realize, and the position of the plug-in connector 102 can be adjusted according to actual needs so as to meet the personalized requirements of users. On the other hand, for the aforementioned bar-shaped connector 102 with an inverted U-shape, two ends of the bottom thereof need to be connected to the connecting beam 104, so that there is a certain requirement for the fixed position precision, and the slidable second connecting member 114 can conveniently and accurately position the two ends, thereby facilitating the accurate installation of the sofa assembly.
