Description

Technical Field

[0001] This application relates to the field of seating technology, and more specifically, to a seat with a lifting function. Background Technology

[0002] With the increasing aging of the population, the living needs of the elderly are receiving more and more attention from society. Among them, due to the weakening of lower limb muscle strength and insufficient knee joint torque, the elderly need to significantly increase the leg support when getting up, which can easily lead to the risk of falling due to instability. Or, the blood circulation disorders caused by prolonged sitting (such as leg numbness) can further aggravate the difficulty of getting up.

[0003] In the current technology, conventional chairs lack devices to help the elderly stand up, which makes it take a lot of time and effort for them to get up. They need to use their arms for support or external push to get up slowly, which is very unfriendly to the elderly.

[0004] Therefore, it is necessary for the inventor to design a new type of chair with a lifting function to overcome the above problems. Summary of the Invention

[0005] The main purpose of this application is to provide a chair with an assistive standing function to solve the problem in related technologies where elderly people have difficulty getting up from a chair.

[0029] like Figures 1 to 3As shown, a seat with a standing-up function includes a leg support assembly 1 and a mounting plate 2 fixedly installed on the leg support assembly 1. A first support plate 3 for supporting the thighs is fixedly disposed at the front end of the mounting plate 2. A second support plate 4 for supporting the buttocks is hinged to the rear end of the first support plate 3. A standing-up assist assembly for driving the second support plate 4 to rotate is fixedly disposed between the bottom of the second support plate 4 and the mounting plate 2. The seat also includes armrest assemblies symmetrically disposed on both sides of the second support plate 4, and the armrest assemblies are fixedly connected to the side walls of the second support plate 4. Specifically, when an elderly person sits on the seat composed of the first support plate 3 and the second support plate 4, and needs to stand up, they place their arms on the armrest assemblies and manipulate the standing-up assist assembly to rotate the second support plate 4 upwards, thereby lifting the buttocks and achieving the standing-up function. During this process, since the armrest assemblies are mounted on the second support plate 4, they rotate synchronously with the second support plate 4, allowing the arms to rest against the armrest assemblies during the standing process, providing stable support for the hands and making the standing up more stable. It should be noted that the outside of the first support plate 3 and the second support plate 4 should also be covered with cloth, which can be used to cover the lifting components and make the patient more comfortable when sitting down. The cloth covered here should not hinder the movement of the second support plate 4 and the armrest components. Therefore, the cloth used for covering can be made of elastic material.

[0030] This embodiment achieves the purpose of supporting and assisting the human body to stand up by setting up a lifting-assisting component to drive the second support plate 4 to flip upward. Furthermore, by setting the handrail component on the second support plate 4, people's arms can move synchronously with their bodies and are always stably supported during the lifting process, making people feel safer when standing up.

[0031] The lifting assist assembly includes a sliding drive component and connecting rods 6. The sliding drive component is fixedly mounted on the mounting plate 2. The output end of the sliding drive component is rotatably connected to one end of the connecting rod 6, and the other end of the connecting rod 6 is rotatably connected to the bottom of the second support plate 4. The sliding drive component is a cylinder 5. A positioning rod 7 is fixedly connected to the end of the cylinder 5. There are two connecting rods 6, symmetrically arranged at both ends of the positioning rod 7, and the ends of both connecting rods 6 are rotatably connected to the positioning rod 7. Specifically, the cylinder 5 pushes the positioning rod 7, the positioning rod 7 pushes the connecting rod 6, and the connecting rod 6 pushes the second support plate 4 to rotate, thus achieving the lifting assist function. Here, two symmetrical connecting rods 6 are set, which typically push the two ends of the second support plate 4, so that the second support plate 4 is subjected to balanced force and rotates smoothly.

[0032] The handrail assembly includes two uprights 8 and one crossbar 9. The bottoms of the two uprights 8 are fixedly connected to the front and rear ends of the side wall of the second support plate 4, respectively, and the bottom of the crossbar 9 is fixedly connected to the tops of the two uprights 8. Specifically, the two uprights 8 simultaneously support the front and rear ends of the crossbar 9, so that the crossbar 9 can stably support the arm when it rotates synchronously, avoiding the risk of falling due to the crossbar 9 breaking at the connection between it and the uprights 8 because of uneven force on the crossbar 9.

[0033] An elastic filler is also provided between the second support plate 4 and the mounting plate 2. Specifically, an elastic filler such as sponge or spring composite can be used between the second support plate 4 and the mounting plate 2. The function of this elastic filler is to provide auxiliary support for the second support plate 4, bear part of the pressure when the user sits on the second support plate 4, and reduce the pressure concentration at the connection between the connecting rod 6 and the second support plate 4 and the positioning rod 7, thereby reducing the risk of breakage at the connection points at both ends of the connecting rod 6. The elastic filler here can be completely filled inside the elastic fabric used to wrap the first support plate 3 and the second support plate 4, but the position of the elastic filler should not interfere with the movement trajectory of the connecting rod 6.

[0034] One of the crossbars 9 is fixedly equipped with an operation button 10 for controlling the lifting assistance component. Specifically, the user can control the speed at which the second support plate 4 rotates and rises by controlling the operation button 10. The operation button 10 is located on the crossbar 9, allowing the user to operate it while their arm is close to the crossbar 9, making the lifting process more stable and safer.

[0035] It also includes a backrest assembly 11, which is fixedly mounted on the top of the rear end of the mounting plate 2. A headrest assembly 12 is also fixedly mounted on the top of the backrest assembly 11. Specifically, the backrest assembly 11 and the headrest assembly 12 make the user more comfortable when sitting.

[0036] The front end of the crossbar 9 extends to the front of the first support plate 3. Specifically, the extended front end of the crossbar 9 can support the user's entire arm, providing better support.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
