Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to a sofa chair. Background Art

[0002] Sofa chairs refer to chairs made by foaming foamed resin. They are lightweight and flexible and are loved by consumers. In order to enhance the support strength of sofa chairs, a support frame is usually added to the foamed resin body. The existing preparation method is to put the support frame into the foaming mold, and the foamed resin is directly coated on the support frame after foaming. The foamed resin body and the support frame are connected by the static friction of the joint surface between the two. With this arrangement, after the chair has been used for a long time, the joint surface between the foamed resin body and the support frame will slowly separate, resulting in the support frame being unable to support the foamed resin body well, or even detaching, affecting the service life of the product.

[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] In the description of the present invention, terms such as "up", "down", "left", "right", "front", "back", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0021] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figures 1 to 3 As shown, a sofa chair provided in this embodiment includes: a support frame 10, a fixing member 30 and a foamed resin body 20 forming a chair body; the foamed resin body 20 forming the chair body refers to a structure in the shape of a chair body obtained by foaming a foamed resin material; as in this embodiment, the foamed resin body 20 is formed with a seat 21, a backrest 22 located at the rear side of the seat 21, and armrests 23 located at the left and right sides of the seat 21. The support frame 10 is connected to the foamed resin body 20 to support the foamed resin body 20, and the fixing member 30 passes through the foamed resin body 20 and is fixed on the support frame 10 to fix the support frame 10 and the foamed resin body 20; the foamed resin body 20 and the support frame 10 are firmly connected, so that the two are not easy to separate, which greatly ensures the stable support of the support frame 10 to the foamed resin body 20 and increases the service life of the product.

[0023] Specifically, in this embodiment, the support frame 10 includes a four-sided frame 11 located at the bottom and a fixing rod 12 fixed on the four-sided frame 11 and extending vertically upward, and the fixing rod 12 penetrates into the foamed resin body 20 from the bottom; the fixing part 30 passes through the foamed resin body 20 from the top of the foamed resin body 20 downward and is fixed on the fixing rod 12.

[0024] Specifically, the four-side frame 11 is embedded in the bottom of the foamed resin body 20 to enhance the hardness of the bottom so as to facilitate ground support.

[0025] Specifically, there are four fixing rods 12 connected to the four ends of the four-sided frame 11, namely two short fixing rods 1 located on the front side and two long fixing rods 2 located on the rear side. The two short fixing rods 1 are respectively passed through the left and right sides of the seat 21; the two long fixing rods 2 are respectively passed through the two sides of the backrest 22.

[0026] Since the height of the seat 21 is relatively low, the short fixing rod 1 is passed through the seat 21 and the distance from the top of the seat 21 is relatively short. Therefore, in the present embodiment, the fixing member 30 fixed to the two short fixing rods 1 is a screw 31. The screw 31 passes through the seat 21 of the foamed resin body 20 and is fixedly screwed on the short fixing rod 1 of the support frame 10. The nut of the screw 31 abuts against the foamed resin body 20 through the first gasket 33. In this way, fixation with the short fixing rod 1 is achieved, and the structural connection is simple and easy to operate. Among them, the first gasket 33 increases the contact area with the foamed resin body 20, making the connection more stable.

[0027] At the same time, since the height of the leaning portion 22 is relatively high, although the long fixing rod 2 is used for penetration, the distance between the long fixing rod 2 and the top of the leaning portion 22 is still relatively long. Therefore, in this embodiment, the fixing member 30 fixed to the two long fixing rods 2 is a connecting rod 32, and the connecting rod 32 is penetrated in the foamed resin body 20. The first end of the connecting rod 32 (the lower end in this embodiment) is fixed to the long fixing rod 2 of the support frame 10, and the second end of the connecting rod 32 (the upper end in this embodiment) is connected to the abutment 36, and the abutment 36 is abutted and limited on the foamed resin body 20; in this way, a firm connection between the long fixing rod 2 and the leaning portion 32 is achieved.

[0028] Furthermore, the first end of the connecting rod 32 is a first screw segment, and is fixedly screwed to the long fixed rod 2 of the support frame 10 through the first screw segment, and the assembly operation is simple. At the same time, the second end of the connecting rod 32 is a second screw segment, and the abutment member 36 includes a nut 35 and a second gasket 34, the nut 35 is screwed to the second screw segment, and the second gasket 34 is arranged between the nut 35 and the foamed resin body 20; a long-distance assembly connection is achieved.

[0029] At the same time, the surface of the foamed resin body 20 is provided with an assembly groove 201, and the fixing member 30 is accommodated in the assembly groove 201 without protruding from the surface of the foamed resin body 20. In this way, during use, it will not directly contact hard objects and cause discomfort.

[0030] The assembly method of the above-mentioned support frame 10 and the foamed resin body 20 can be that the foamed resin body 20 is integrally wrapped on the support frame 10 by foaming, and then assembled and fixed by the fixing member 30; or it can be that the foamed resin body 20 reserves space when foaming, and then the support frame 10 and the foamed resin body 20 are connected by assembly, and finally assembled and fixed by the fixing member 30.

[0031] The above structures and connection methods of the support frame 10, the fixing member 30 and the foamed resin body 20 are all preferred embodiments of the present application. Of course, the structure of the sofa chair of the present application may not be limited to this; for example, in other embodiments, the foamed resin body 20 may not be provided with a backrest 22 or an armrest 23, etc.; the structure of the support frame 10 may also be selected according to actual conditions, such as the four-sided frame 11 may be replaced with a triangular frame, a pentagonal frame, etc., and the number of fixing rods 12 may also be set to two, three or other, etc.; the fixing member 30 may also be a riveted member, a clamping member, etc. As long as the support frame 10 and the foamed resin body 20 are fixed by the fixing member 30, it will be fine.

[0032] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
