Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present application will be described more fully below with reference to the accompanying drawings. Some embodiments of the present application are presented in the figures. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, in conjunction with fig. 9, the sofa frame of the present application provides an embodiment, which includes a support frame 101 and a plurality of plug connectors 102, the support frame 101 defines a first support area at the top for supporting a cushion 12 of the sofa and a second support area surrounding the first support area for supporting one or more of a back cushion 10 or an armrest 11 of the sofa, the plug connectors 102 include oppositely disposed fixing ends 103 and an insertion portion 104, the plug connectors 102 are connected with the support frame 101 through the fixing ends 103 such that the insertion portion 104 protrudes upward to the top of the second support area at a set height, and the insertion portion 104 can be inserted into the back cushion 10 or the armrest 11 of the sofa to connect the back cushion 10 or the armrest 11 at the second 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, such as the back pads 10 or the armrests 11.

Referring to fig. 9, it should be noted that, in order to achieve the assembly, the sofa component to be assembled needs to have a connection structure that is matched with the plug connector 102, for example, the sofa component needs to have a slot 105 into which the insertion portion 104 of the plug connector 102 can be inserted, the slot 105 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 insertion portion 104. When assembling the sofa assembly, the notch 105 at the bottom of the sofa assembly is aligned with the insertion portion 104 of the connector 102, and then the sofa assembly is pushed downward to be sleeved into the insertion portion 104 until the bottom plane of the sofa assembly contacts the top surface of the sofa frame, and then the connector 102 is sleeved in the inner cavity of the sofa assembly, thereby completing the assembling 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.

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 according to different needs and uses, for example, in some cases, the sofa may only require the back pad 10 and not the arm rest 11, in which case, only the corresponding connector 102 for connecting the back pad 10 may be provided at the rear side of the sofa frame. Referring to fig. 8, in the present embodiment, a sofa having a pair of cushions 10 and armrests 11 is illustrated, wherein the pair of armrests 11 are respectively disposed at the left and right sides of the sofa frame, and the number of cushions 10 is two, so that the second supporting region for supporting the pair of cushions 10 and the pair of armrests 11 is U-shaped.

Referring to fig. 1 and 2, in conjunction with fig. 8, in one or more embodiments, to more securely position and connect the back pad 10 or armrest 11, the plug 102 is an inverted U-shaped bar having fixed ends 103 at each end. Thus, when the plug connector 102 is connected to the support frame 101 through the two fixed ends 103, the whole U-shaped portion is inserted into the corresponding notch 105 and the inner cavity of the sofa component as an insertion end, and by controlling the width of the U-shaped portion, the whole width of the plug connector 102 can be matched with the size of the sofa component to be assembled, and the plug connector has enough rigidity and strength, can resist deformation, and is practical. Further, the bar member in the inverted U-shape may be an integral bar member, or may be formed by combining several components, which is not limited herein.

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, insert 102 is a cylindrical docking post, and a sofa assembly is configured with a plurality of docking posts 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 back pad 10 or the armrest 11 nested in place, such as a snap provided on the plug 102.

Referring to fig. 1 and 2, in one or more embodiments, the sofa frame further includes a number of connectors 106, the number of connectors 106 corresponds to the number of the fixing ends 103, the connectors 106 are slidably and lockably connected to the support frame 101, and the plug connector 102 is connected to the support frame 101 through the connectors 106. 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. In particular, for the aforementioned bar member with an inverted U-shape, the two fixing ends 103 need to be connected with the supporting frame 101, so that there is a certain requirement for the precision of the fixing position, and the slidable connecting member 106 can conveniently and accurately position the pair of fixing ends 103, thereby facilitating the accurate installation of the sofa assembly. Thus, when the sofa frame is installed, the connecting member 106 is fixed by operating, for example, a locking structure such as a screw to lock the connecting member 106 to the support frame 101 after the connecting member 106 is positioned at the correct position. If the position of the connecting member 106 needs to be adjusted, only the locking structure needs to be unlocked.

Referring to FIG. 2, in one or more embodiments, the connector 106 includes a plug portion 107, the fixed end 103 of the plug 102 includes a socket, and the plug portion 107 nestingly engages the socket. In this way, the connector 102 can be inserted into the connecting member 106 in a manner similar to the assembly of the back pad 10 and the armrest 11, and the connection with the supporting frame 101 can be conveniently realized. Further, to prevent the plug 102 from falling off the connector 106, the two may be fastened with a fastener such as a screw.
