Mode for Carrying Out the Invention

[0016] Hereinafter, specific examples of the present invention will be described in more detail. It should be understood that the description of the embodiments of the present invention is not used to limit the protection scope of the present invention.

[0017] FIG. 1 is a configuration diagram of the full sponge compressible sofa provided in the first embodiment of the present invention. As shown in FIG. 1, the aforementioned full sponge compressible sofa includes a sponge mount 10 and at least one sponge sofa sheet 20 provided on the sponge mount 10. The aforementioned full sponge compressible sofa also includes other functional modules such as an assembly. These should be well-known technologies to those skilled in the art and will not be described in detail here.

[0018] The sponge mount 10 includes a base 11, two armrests 12 symmetrically arranged on the base 11, and at least one mounting protrusion 13 arranged on the side of the base 11 facing the sponge sofa mount 20. The base 11 and the armrests 12 are integrally formed so that the overall structure of the sponge mount 10 is stable.

[0019] The base 11 is for supporting the sponge sofa sheet 20. Since the base 11 will be described in detail in relation to the sponge sofa sheet 20, it will not be described in detail here.

[0020] Each armrest 12 includes an armrest body 121 and a limit flange 122 provided on one side of the armrest body 121. The side where the limit flange 122 of any one of the armrests 12 is provided faces the other armrest 12, whereby the position of the sponge sofa sheet 20 on the base 11 is restricted via the limit flange 122. Therefore, the armrest 12 will be described in detail in relation to the sponge sofa sheet 20.

[0021] The mounting protrusion 13 is provided on the side of the base 11 facing the sponge sofa sheet 20. The mounting protrusion 13 is provided horizontally or vertically on one side of the base 11 to regulate the position of the sponge sofa sheet 20 on the sponge mount 10. The mounting protrusion 13 will be described in detail in accordance with the sponge sofa sheet 20.

[0022] Each sponge sofa sheet 20 includes a cushion 21, a backrest 22 provided at one end of the cushion 21, and a mounting groove 23 provided on the side of the cushion 21 facing the sponge mount 10.

[0023] The cushion 21 is provided on the sponge mount 10. The base 11 supports the cushion 21 and maintains a comfortable height when the user sits on the cushion 21. The distance between the two armrest bodies 121 is equal to an integer multiple of the length of the cushion 21. The sponge mount 10 can be processed as required, and the sponge sofa sheet 20 can be attached to form a single-seat sofa, a two-seat sofa, or a multi-seat sofa. When the sponge sofa sheet 20 is attached to the sponge mount 10, the limit flange 122 of each armrest 12 abuts against the cushion 21 of the sponge sofa sheet 20 to regulate the position of the sponge sofa sheet 20 on the sponge mount 10.

[0024] The backrest 22 is used to support the waist of the human body. The cushion 21 and the backrest 22 are integrally formed. The side wall of the backrest 22 on the side facing the cushion 21 is provided in an inclined manner. Moreover, the angle between the cushion 21 and the backrest 22 is an obtuse angle, which conforms to human mechanics and provides a comfortable sitting position for the user. Also, along the extending direction of the armrest body 121, the length of the limit flange 122 is smaller than the length of the armrest body 121. The head at one end of the limit flange 122 is flush with the end face at one end of the armrest body 121. Between the limit flange 122 and the armrest body 121, it is formed in a stepped shape to facilitate the attachment of the backrest 22 in the sponge sofa sheet 20 and to ensure that the sponge mount 10 and the sponge sofa sheet 20 are neatly attached.

[0025] The mounting concave grooves 23 of each sponge sofa sheet 20 are all installed integrally with one mounting protrusion 13. The mounting concave grooves 23 and the mounting protrusions 13 are in an interference fit so that the sponge mount 10 and the sponge sofa sheet 20 are stably connected.

[0026] Also, both the sponge mount 10 and the sponge sofa sheet 20 are made of sponge. The sponge is a plastic product produced by the gelation reaction by adding TDI or MDI to polyurethane, and various densities can be represented according to the size of the internal bubbles. It can be molded into various shapes as required. The sponge adopted in the present invention is commonly used in the prior art. Also, since both the sponge mount 10 and the sponge sofa sheet 20 are made of sponge, during transportation, the sponge mount 10 and the sponge sofa sheet 20 can be compressed to reduce the volume and facilitate transportation. When transportation is required, the sponge mount 10 and the sponge sofa sheet 20 can be compressed through mechanical equipment, thereby squeezing out the air in the sponge, reducing the volume of the sponge mount 10 and the sponge sofa sheet 20, and further reducing the packaging volume, thereby facilitating transportation. At the same time, each time the same container is transported, 3 to 4 times more can be loaded, achieving the purpose of reducing transportation costs.

[0027] As shown in FIG. 1, in the first embodiment of this full-sponge compressible sofa, two sponge sofa sheets 20 are attached to the sponge mount 10 to form a two-seater sofa.

[0028] FIG. 5 is a schematic structural view of the full-sponge compressible sofa provided in the second embodiment of the present invention. In the second embodiment of the aforementioned full-sponge compressible sofa, the base 11 includes two base bodies 111. The two armrests 12 are respectively provided on the two base bodies 111. Since the base 11 is divided into two parts, during transportation, the base 11 can be disassembled and rationally arranged for transportation.

[0029] In the installation process of the first or second embodiment, for this full-sponge compressible sofa, a sponge sofa sheet 20 is inserted between the two armrests 12, and the limit flange 122 of each armrest 12 is abutted against the cushion 21 of the sponge sofa sheet 20 to regulate the position of the sponge sofa sheet 20 on the sponge mount 10, thereby realizing rapid installation.

[0030] Compared with the prior art, the full-sponge compressible sofa provided by the present invention is integrally combined with the sponge mount 10 through the sponge sofa sheet 20. On the base 11 of the sponge mount 10, two armrests are symmetrically provided. Each armrest 12 includes an armrest body 121 and a limit flange 122 provided on one side of the armrest body 121. Each sponge sofa sheet 20 includes a cushion 21 and a backrest 22 provided at one end of the cushion 21. When the sponge sofa sheet 20 is attached to the sponge mount 10, the limit flange 122 of each armrest 12 abuts against the cushion 21 of the sponge sofa sheet 20 to regulate the position of the sponge sofa sheet 20 on the sponge mount 10. Thereby, the sponge sofa sheet 20 and the sponge mount 10 are integrally formed so as to realize rapid attachment between the sponge sofa sheet 20 and the sponge mount 10. The installation of this full-sponge compressible sofa is convenient and can be assembled or disassembled according to needs, bringing great convenience to the transportation and handling operations of the sofa.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Modifications, equivalent substitutions, or improvements within the spirit of the present invention are included in the scope of the claims.
