They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.
[0049] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 7 illustrate.
[0050] This embodiment provides a leisure sofa, which is applied in the field of household goods technology. Specifically, as shown in... Figures 1 to 7 As shown, the sofa includes a protective cover, a main body 1, and filling material. The main body 1 is fitted inside the protective cover and has an inner space. The filling material is used to fill the inner space. In this embodiment, the filling material can be selected from materials such as particles, memory foam, sponge, cotton, or a mixture of cotton particles. The particles can move and rearrange freely according to external forces and shape changes, flexibly adapting to different forces and shape changes, providing uniform support and a comfortable feel, and can also be recycled. The main body 1 includes a first seating part 11 and a second seating part 12, which are connected. The first seating part 11 and the second seating part 12 are distributed along the length direction, and the angle between the first seating part 11 and the second seating part 12 can be changed to convert into various usage states for user use. This allows users to choose from multiple sitting postures and supports flexible adjustment. When the user operates, it is simple, convenient, and effortless. This design can improve the utilization rate of the sofa, meet the personalized needs of different user groups, enhance the comfort and practicality of the sofa, and improve the user's comfort and experience. The first seating section 11 and the second seating section 12 have an angle between their seating surfaces, which can range from 10° to 90°. By setting the angle range, the sofa body can provide a more flexible and diverse seating experience in different usage states, and can also achieve seamless switching between various postures such as fully half-sitting and upright.
[0051] It should be noted that the material of the filler is not limited to the above embodiments, as long as it can fill the internal space.
[0052] Furthermore, such as Figures 1 to 3 As shown, the first seating part 11 and the second seating part 12 are integrally formed, which can enhance the overall strength of the sofa, avoid loosening or breakage at the joints, improve the stability and durability of the sofa structure, and extend the service life of the sofa.
[0053] Furthermore, such as Figure 6 As shown, when the first seating part 11 and the second seating part 12 are close to the same plane, the first seating part 11 forms a seat cushion and the second seating part 12 forms a backrest cushion. The main body 1 is in the first use state, and the user can lie flat at nearly 180° to achieve a comfortable sleeping state. It is a small mattress that allows the user to lie face down or lie down, thus improving the user's comfort.
[0054] Furthermore, such as Figure 7 As shown, when the first seating section 11 and the second seating section 12 are close to the same plane, the first seating section 11 forms a seat cushion, the second seating section 12 forms a seat cushion, and the main body 1 is in a second usage state. One user can sit on the first seating section 11, and another user can sit on the second seating section 12, which is convenient for multiple users and meets the needs of multiple people using it at the same time. It is also easy to quickly switch to a single-person usage state, which has good flexibility and practicality.
[0055] Furthermore, such as Figure 4 , Figure 5 As shown, the first seating section 11 and the second seating section 12 are rotated 90° relative to each other. When the height of the first seating section 11 is higher than the height of the second seating section 12, the first seating section 11 forms a backrest, and the second seating section 12 forms a seat cushion, placing the main body 1 in a third usage state. When the user sits on the second seating section 12 and lies on the first seating section 11, the user's back rests against the first seating section 11, forming a comfortable obtuse angle. The first seating section 11 effectively supports the user's waist and back, providing good support and allowing the user to relax and lean back in a relaxed posture, thus improving overall user comfort.
[0056] Furthermore, such as Figure 7 As shown, the first seating section 11 and the second seating section 12 are rotated 90° relative to each other. When the height of the first seating section 11 is higher than the height of the second seating section 12, both the first and second seating sections 11 and 12 form a seat, and the main body 1 is in its fourth usage state. One user can sit on the first seating section 11, and another user can sit on the second seating section 12, facilitating use by multiple users and meeting the needs of simultaneous use by multiple people. It also allows for quick conversion to a single-person usage state, demonstrating good flexibility and practicality.
[0057] Furthermore, when the first seating section 11 is nearly perpendicular to the ground, it forms a backrest, and the second seating section 12 forms a seat cushion, placing the main body 1 in its fifth usage state. When the user sits on the second seating section 12, their back can rest against the first seating section 11. At this time, the first seating section 11 is nearly perpendicular to the ground, and the first seating section 11 and the second seating section 12 form an L-shape, providing solid back support for the user and helping to maintain good posture. The user can sit and read or do other leisure activities, effectively reducing back pressure, improving comfort and support, and ensuring a good user experience.
[0058] Furthermore, such as Figures 1 to 3 As shown, the first seating section 11 includes a first seating surface 111 and two second seating surfaces 112 disposed on both sides of the first seating surface 111; the second seating section 12 includes a third seating surface 121 and two fourth seating surfaces 122 disposed on both sides of the third seating surface 121; wherein, the second seating surface 112 and the third seating surface 121 are connected by an arc transition, and the first seating surface 111 and the fourth seating surface 122 are connected by an arc transition. The arc transition makes the transition between the seating surfaces smoother, avoiding sharp edges or abrupt turns, reducing the discomfort of users when sitting or lying down, and improving the comfort of the seating experience. At the same time, the arc transition also helps the first seating section 11 and the second seating section 12 to adjust relative to each other in different usage states, reducing friction and improving the smoothness of user operation.
[0059] Viewed from the horizontal direction, such as Figure 3 As shown, the diameter of the first seating surface 111 is smaller than the diameter of the second seating surface 112, and the diameter of the third seating surface 121 is smaller than the diameter of the fourth seating surface 122. The side of the first seating part 11 away from the second seating part 12 has an arc-shaped structure, and the side of the second seating part 12 away from the first seating part 11 also has an arc-shaped structure. The elasticity of the second seating surface 112 is greater than that of the first seating surface 111, and the elasticity of the third seating surface 121 is greater than that of the fourth seating surface 122. The second seating surface 112 and the third seating surface 121, which have greater elasticity, can provide stronger rebound and support, effectively supporting the user's body weight and reducing fatigue during long-term sitting, for example, when the main body 1 is in the third, fourth, and fifth usage states. The first seating surface 111 and the fourth seating surface 122, which have less elasticity, provide moderate softness and increase the comfort of sitting, for example, when the main body 1 is in the first and second usage states. By flipping the seating surfaces with different elasticities to the desired position, different usage states of the main body 1 can be achieved.
[0060] It should be noted that the elasticity of the second seating surface 112 is less than that of the first seating surface 111, and the elasticity of the third seating surface 121 is less than that of the fourth seating surface 122; or the elasticity of the first seating surface 111 is equal to that of the second seating surface 112, and the elasticity of the third seating surface 121 is equal to that of the fourth seating surface 122; or the elasticity of the first seating surface 111 is equal to that of the third seating surface 121, and the elasticity of the second seating surface 112 is equal to that of the fourth seating surface 122. The elasticity between the first seating surface 111, the second seating surface 112, the third seating surface 121, and the fourth seating surface 122 is not limited to the above embodiments, as long as an effective connection between the seating surfaces is achieved, ensuring the stability and comfort of the overall structure of the sofa.
[0061] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
