[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-4 A foldable and deformable sofa bed includes a sofa cushion 8. The sofa cushion 8 has a first edge 1 and a second edge 4 on its side. Both the first edge 1 and the second edge 4 are U-shaped, forming an accommodating space between the first edge 1 and the second edge 4. The sofa cushion 8 is located in this accommodating space, and one edge of the sofa cushion 8 is connected to the inner wall of the first edge 1. In actual use, the sofa cushion 8 can be surrounded by the first edge 1 and the second edge 4, so that the sofa cushion 8, the first edge 1, and the second edge 4 form a bed for the user to sleep and rest.
[0024] like Figure 1 and Figure 4 As shown, the sofa cushion 8, the first edge 1, and the second edge 4 all include spring packs 6. Several springs 5 are installed inside the spring pack 6, and a sponge layer 13 is wrapped around the outer surface of the spring pack 6. A fabric layer 12 is connected to the outer surface of the sponge layer 13. In actual use, the springs 5 and the spring pack 6 can support the user, the sponge layer 13 can cushion the user, and the fabric layer 12 can block external dust from the outside of the sponge layer 13, resulting in good dustproof effect.
[0025] It should be noted that, as Figure 2 As shown, the tops of the first edge 1 and the second edge 4 are connected by a connecting strap 17, so that when the first edge 1 and the second edge 4 are laid around the sofa cushion 8, the second edge 4 will not separate from the first edge 1 and the sofa cushion 8.
[0026] like Figure 1 and Figure 2 As shown, a fixing strap 2 is installed on the top edge of the first sidewall 1, and a first zipper strap 3 is connected to one side of the fixing strap 2. A second zipper strap 15 is connected to the bottom edge of the second sidewall 4. When the second sidewall 4 is stacked on the first sidewall 1, the top of the fixing strap 2 extends to one side of the second sidewall 4, and the first zipper strap 3 and the second zipper strap 15 are connected by a zipper. In actual use, when the second sidewall 4 is stacked on the first sidewall 1, the first sidewall 1, the second sidewall 4 and the sofa cushion 8 form a sofa shape for the user to use. Under the action of the fixing strap 2, the first sidewall 1 and the second sidewall 4 can be fixed together, so that when the user leans on the second sidewall 4, the second sidewall 4 will not shift significantly.
[0027] It should be noted that the fixing strap 2 is made of canvas material, which has poor elastic deformation ability. When the user leans against the second side 4, the fixing strap 2 can effectively limit the second side 4 and prevent the second side 4 from shifting too far and affecting the user's use.
[0028] like Figure 2 and Figure 4 As shown, the top of the sofa cushion 8 has a receiving groove 11, and the bottom of the receiving groove 11 is connected to a heating film 9. The receiving groove 11 also has a sponge pad 7 inside, and the bottom of the sponge pad 7 has a groove 14. When the sponge pad 7 is in the receiving groove 11, the heating film 9 is in the groove 14. The heating film 9 can heat the sponge pad 7, so that when the user sits on the sofa cushion 8 or lies on the surface of the sofa cushion 8, the heating film 9 can heat the user's body and improve the comfort of use.
[0029] It should be noted that when the heating film 9 is damaged, the user can remove the sponge pad 7 from the receiving groove 11, then take out the damaged heating film 9, put the new heating film 9 into the receiving groove 11, then pass the wire 16 through the wiring groove 10, and then cover it with the sponge pad 7 to complete the replacement. The replacement is convenient.
[0030] like Figure 1 As shown, when the sponge pad 7 is located in the receiving groove 11, the edge of the sponge pad 7 is in clearance fit with the inner wall of the receiving groove 11, and the top of the sponge pad 7 is flush with the top opening of the receiving groove 11. In this way, when the user lies or sits on the sofa cushion 8, the gap between the sponge pad 7 and the receiving groove 11 will not cause any obstruction to the user.
[0031] like Figure 1 and Figure 2 As shown, wiring grooves 10 are provided at the bottom of the sponge pad 7, one top end of the sofa cushion 8, and near the ends of the first and second edging 1 and 4. One end of the heating film 9 is connected to a wire 16, and one end of the wire 16 passes through the wiring groove 10 and is connected to an external power source. The cooperation between the wire 16 and the wiring groove 10 can protect the wire 16 during wiring and will not obstruct the wire 16 when adjusting the position of the second edging 4.
[0032] Specifically, in use, when the user needs to sleep, the first edge 1 and the second edge 4 can be laid flat, and the second edge 4 and the first edge 1 will surround the sofa cushion 8. Figure 2 As shown, the user can lie on the sofa cushion 8 to sleep. When the user needs to use the sofa, the user can rotate the second side 4 and fold it over the first side 1. Then, the free side of the fixing strap 2 is flipped to one side of the second side 4. Then, the first zipper strap 3 and the second zipper strap 15 are connected together by a zipper to fix the second side 4 and the first side 1 together. In this way, the first side 1, the second side 4 and the sofa cushion 8 form a sofa for the user to use, improving the usage effect. When the external ambient temperature is low, the staff can connect the wire 16 to an external power source, and the heating film 9 will be powered on to heat the sponge pad 7. The sponge pad 7 will then transfer the heat to the user's body to keep the user warm and improve the usage effect.
[0033] Furthermore, such as Figure 2 As shown, the tops of the first edge 1 and the second edge 4 are flush with the top of the sofa cushion 8. This way, when the first edge 1 and the second edge 4 are laid flat, the first edge 1, the second edge 4, and the top of the sofa cushion 8 will remain flush, which will not affect the user's use.
[0034] Furthermore, the outer surface of the heating film 9 is provided with an insulating film, which is made of polyester film or other flexible insulating film. This can wrap the heating film 9 for insulation protection and prevent leakage when the heating film 9 is damaged.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
