Description

Technical Field

[0001] The invention relates to a lever-type elastic director's chair, belonging to the technical field of director's chairs. Background Art

[0002] The existing steel-cloth structure folding chair uses steel alloy pipes as the frame and Oxford cloth as the seat cushion fabric, which can be folded naturally with the frame. The left-right or front-back folding chair is more comfortable than the steel-wood structure chair, and is more commonly used in more casual working environments, such as performance venues, and is often used as a director's seat, so it is also called a director's chair.

[0003] However, after the user sits on the director's chair, the user's posture is fixed, which is not conducive to rest.

[0004] The present invention proposes a new solution to the above problems. Summary of the invention

[0005] The main purpose of the present invention is to solve the problem that after a user sits on the director's chair, the user's posture is fixed, which is not conducive to rest, and to provide a lever-type elastic director's chair.

[0006] The purpose of the present invention can be achieved by adopting the following technical solutions:

[0007] A lever-type elastic director's chair comprises a director's chair body, a base, an articulated seat and a connecting arm, wherein a first connecting seat and a second connecting seat are arranged on the base, a third connecting seat is fixedly connected to the surface of the director's chair body, a buffer mechanism is arranged between the articulated seat and the second connecting seat, the surface of the articulated seat is rotatably connected to the connecting arm and the third connecting seat respectively, and an inner wall of the first connecting seat is rotatably connected to the connecting arm.

[0008] Preferably, the buffer mechanism comprises a shell, a connecting plate and a connecting rod, and a through hole is provided on the upper surface of the shell.

[0009] Preferably, a threaded portion is provided at one end of the connecting rod, and a threaded hole threadably connected to the threaded portion is provided on the surface of the connecting plate.

[0010] Preferably, one end of the threaded portion is fixedly connected to a limiting plate, and one end of the connecting rod is fixedly connected to an upper baffle.

[0011] Preferably, a connection block is fixedly connected to the upper surface of the upper baffle, a first mounting seat is fixedly connected to the upper surface of the connection block, and a second mounting seat is fixedly connected to the end of the housing away from the first mounting seat.

[0012] Preferably, a lower baffle is fixedly connected to the surface of the shell, and a spring is provided between the lower baffle and the upper baffle.

[0013] Preferably, a piston is fixedly connected to the surface of the connecting plate, and an inner wall of the outer shell is slidably connected to the piston.

[0014] The beneficial technical effect of the present invention is as follows: when the user sits on the director's chair and leans back, the main body of the director's chair rotates around point A. Under the action of the user's body weight, the buffer mechanism performs buffering, and the hinged seat rotates around point C. The side length of the triangle composed of ABC changes, and the connecting arm rotates accordingly, and the main body of the director's chair also tilts backward. When the reaction force of the buffer mechanism is balanced with the user's body weight, the position of the chair is determined accordingly. Any movement of the user's body will destroy the balance of the chair. The chair shakes to provide a comfortable resting place, help relax the body and mind, relieve stress, help improve sitting posture, reduce back fatigue, promote blood circulation, help relax muscles and relieve muscle stiffness, and gentle shaking can help users relax, lower heart rate, and reduce anxiety.

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0021] like Figure 1-Figure 4As shown, the lever-type elastic director's chair provided in this embodiment includes a director's chair main body 1, a base 2, an articulated seat 6 and a connecting arm 5. The base 2 is provided with a first connecting seat 3 and a second connecting seat 4. The surface of the director's chair main body 1 is fixedly connected with a third connecting seat 7. A buffer mechanism is provided between the articulated seat 6 and the second connecting seat 4. The surface of the articulated seat 6 is rotatably connected to the connecting arm 5 and the third connecting seat 7 respectively. The inner wall of the first connecting seat 3 is rotatably connected to the connecting arm 5. The bottom of the director's chair main body 1 is hinged to the first connecting seat 3. The connection between the director's chair main body 1 and the first connecting seat 3 is set as point A, the connection between the connecting arm 5 and the articulated seat 6 is set as point B, the connection between the articulated seat 6 and the third connecting seat 7 is point C, and the director's chair main body 1 is supported by point A. When the user sits on the director's chair and leans back, the director's chair body 1 rotates around point A. Under the action of the user's body weight, the buffer mechanism performs buffering, and the articulated seat 6 rotates around point C. The side length of the triangle composed of ABC changes, and the connecting arm 5 rotates accordingly. The director's chair body 1 also tilts backward. When the reaction force of the buffer mechanism is balanced with the user's body weight, the position of the chair is determined accordingly. Any movement of the user's body will destroy the balance of the chair. The chair shakes to provide a comfortable resting place, help relax the body and mind, relieve stress, help improve sitting posture, reduce back fatigue, and promote blood circulation. It helps relax muscles and relieve muscle stiffness. Gently shaking can help users relax, lower heart rate, and reduce anxiety.

[0022] In this embodiment, if Figure 1-Figure 4 As shown, the buffer mechanism includes a shell 8, a connecting plate 11 and a connecting rod 9. A through hole 13 is provided on the upper surface of the shell 8. A threaded portion 10 is provided at one end of the connecting rod 9. A threaded hole threadedly connected to the threaded portion 10 is provided on the surface of the connecting plate 11. One end of the threaded portion 10 is fixedly connected to a limiting plate 19. One end of the connecting rod 9 is fixedly connected to an upper baffle 14. A connecting block 15 is fixedly connected to the upper surface of the upper baffle 14. A first mounting seat 16 is fixedly connected to the upper surface of the connecting block 15. The shell 8 is fixedly connected to a second mounting seat 17 at one end away from the first mounting seat 16. A lower baffle 18 is fixedly connected to the surface of the shell 8. A stopper 18 is provided between the lower baffle 18 and the upper baffle 14. There is a spring 20, and the surface of the connecting plate 11 is fixedly connected with a piston 12. The inner wall of the outer shell 8 is slidably connected to the piston 12. When the buffer mechanism is working, the outer shell 8 and the connecting rod 9 move relative to each other, so that the piston 12 and the surface of the outer shell 8 slide, thereby causing the spring 20 to deform and produce buffering. Before the buffer mechanism is installed, the connecting block 15 is rotated to rotate the connecting rod 9, thereby causing the threaded portion 10 and the connecting plate 11 to rotate relative to each other, thereby adjusting the extended length of the connecting rod 9, thereby adjusting the elastic force of the spring 20. The limiting plate 19 makes it difficult for the threaded portion 10 to separate from the connecting plate 11, and the piston 12 fits tightly with the outer shell 8, making it difficult for the piston 12 to rotate.

[0023] In this embodiment, if Figure 1-Figure 4 As shown, the working principle of the lever-type elastic director chair provided in this embodiment is as follows:

[0024] The connecting block 15 is rotated, so that the connecting rod 9 is rotated, and the threaded portion 10 and the connecting plate 11 are relatively rotated, so as to adjust the extended length of the connecting rod 9, thereby adjusting the elastic force of the spring 20. The limit plate 19 makes it difficult for the threaded portion 10 to separate from the connecting plate 11, and the piston 12 is tightly fitted with the shell 8, so that the piston 12 is not easy to rotate. When the user sits on the director's chair and leans back, the director's chair body 1 rotates with point A as the center. Under the action of the user's weight, the buffer mechanism performs buffering, and the articulated seat 6 rotates with point C as the center. The side length of the triangle composed of ABC changes, and the connecting arm 5 rotates accordingly, and the director's chair body 1 also tilts backward. When the reaction force of the buffer mechanism is balanced with the user's body weight, the position of the chair is determined accordingly. Any movement of the user's body will destroy the balance of the chair. The chair shakes, providing a comfortable resting place, helping to relax the body and mind, relieve stress, help improve sitting posture, reduce back fatigue, and promote blood circulation. It helps to relax muscles and relieve muscle stiffness. Gently shaking can help users relax, reduce heart rate, and reduce anxiety.

[0025] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
