Description

TECHNICAL FIELD

[0001] The utility model relates to a chair structure, in particular to a chair structure capable of forming a seesaw reciprocating action or a fixed-point balancing action through foot stepping or foot placing. BACKGROUND

[0002] Traditional chairs are usually simple in structure and mainly provide basic seating functions, lacking sufficient dynamic characteristics. In modern work environments, many people need to sit at desks for long periods, and such static postures can lead to various health problems. Studies have shown that long periods of sitting can lead to the accumulation of abdominal fat, increase the risk of metabolic diseases, and cause discomfort such as back pain and muscle fatigue.

[0003] Long periods of sitting not only affect the distribution of abdominal fat but also affect overall blood circulation. When the body maintains the same posture for a long time, muscles do not get enough activity, which can lead to muscle atrophy and tightness. In addition, fixed sitting postures can cause uneven pressure on the spine, increasing the risk of back pain, neck pain, and other problems. This situation is particularly common among office workers and has a significant impact on health. UTILITY MODEL

Thus, a first component can also be referred to as a second component. The combination of components / units / circuits in the present disclosure is not a combination that is generally known, conventional or known in the art, and cannot be determined by whether the components / units / circuits themselves are known.

[0066] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A and Figure 4B , wherein Figure 1 is a perspective view illustrating a chair structure 100 according to a first embodiment of the present disclosure; Figure 2 is an exploded view illustrating the chair structure 100 according to Figure 1 ; Figure 3 is a side view illustrating the chair structure 100 according to Figure 1 at a first position P1; Figure 4A is a partial enlarged view illustrating an adjustable hydraulic damping unit 160 of the chair structure 100 according to Figure 3 ; and Figure 4B is a partial enlarged view illustrating the damping unit 150 of the chair structure 100 according to Figure 3 . The chair structure 100 is used for a user (not shown in the figure) to sit and step on. The chair structure 100 includes a pivot seat 110, a support rod 120, a seat cushion 130, a footrest 140, a damping unit 150 and an adjustable hydraulic damping unit 160.

[0067] The pivot base 110 comprises a pivot portion 111, a base tube portion 112, and four roller portions 113 (four in the first embodiment, but not limited thereto). The base tube portion 112 comprises a first base tube (not labeled separately), a second base tube (not labeled separately), and a third base tube (not labeled separately). One end of the second base tube is fixedly connected to the first base tube. One end of the third base tube is fixedly connected to the first base tube. The first roller portion 113 and the second roller portion 113 are respectively arranged at the two ends of the first base tube, the third roller portion 113 is arranged at the other end of the second base tube, and the fourth roller portion 113 is arranged at the third base tube. In this way, by arranging the base tube portion 112, a firm support structure is formed, which enhances the stability of the overall chair structure 100 and ensures safe and reliable use during use. In addition, the arrangement of the four roller portions 113 further enhances its mobility and convenience, allowing the user to easily move the chair.

[0068] The support rod 120 is pivotally arranged in the pivot base 110 and comprises a first support rod end portion 121, a second support rod end portion 122, and a support rod body portion 123. The first support rod end portion 121 is pivotally arranged in the seat cushion portion 130. The second support rod end portion 122 is opposite to the first support rod end portion 121. The support rod body portion 123 connects the first support rod end portion 121 and the second support rod end portion 122 and is pivotally arranged in the pivot portion 111 of the pivot base 110. In this way, the arrangement of the support rod body portion 123 pivotally arranged in the pivot portion 111 allows the support rod 120 to be flexibly swung by the user's operation to produce a similar seesaw action.

[0069] The seat cushion portion 130 comprises a lifting piece 131, a pivot piece 132, an adjusting piece 133, a seat cushion piece 134, and a backrest piece 135. The lifting piece 131 is arranged below the seat cushion piece 134, wherein when the user pulls the adjusting piece 133, the lifting piece 131 will rise or fall due to the change in gas pressure, so that the seat cushion portion 130 can be adjusted in height. The pivot piece 132 is fixedly arranged on the outer surface of the lifting piece 131 and is provided for the first support rod end portion 121 to be pivotally arranged. One end of the adjusting piece 133 is connected between the lifting piece 131 and the seat cushion piece 134. The seat cushion piece 134 is connected between the lifting piece 131 and the backrest piece 135 for the user to sit on. The side edge of the seat cushion piece 134 has a seat cushion curved surface (not labeled separately), which faces the support rod 120. In this way, by arranging the seat cushion curved surface, the body curve of the user can be better adapted, especially for the position of the knee, to improve the naturalness of the sitting posture and enhance the overall comfort.

[0070] In the first embodiment, the chair structure 100 can further include a latch 170. The pivot member 132 penetrates a limiting hole 1321. The latch 170 is arranged in the limiting hole 1321. In this way, the displacement state of the cushion part 130 is controlled. When the latch 170 is pulled out and the stop point (not labeled) is separated from the limiting hole 1321, the stop point in the pivot member 132 will be separated from the limiting hole 1321, so that the cushion part 130 is in a freely adjustable state. The user can adjust the height position of the cushion part 130 according to the needs to meet different sitting posture requirements, thereby improving the ergonomic comfort. When the latch 170 is pushed in and the stop point is clamped into the limiting hole 1321, the cushion part 130 is locked in a fixed position and no longer produces up and down displacement, ensuring that the cushion part 130 will not accidentally slide during use, thereby improving stability and safety.

[0071] The footrest part 140 is connected to the second support end 122 of the support rod 120 and is provided with a plurality of non-slip pads (not labeled) on the bottom surface. In this way, the configuration of the non-slip pads provides good grip, enhancing the stability when using the chair structure 100, thereby improving the safety of the user.

[0072] The buffer unit 150 is pivotally arranged in the pivot seat 110 and located below the support rod body 123 and includes a buffer seat pipe 151, a buffer shaft 152, and a buffer cushion 153. The buffer seat pipe 151 is pivotally arranged in the pivot part 111 and includes a stop top surface 1511 and a stop bottom surface 1512 opposite to the stop top surface 1511. The stop bottom surface 1512 is the pipe groove bottom surface of the buffer seat pipe 151, and the stop top surface 1511 is the pipe opening end surface of the buffer seat pipe 151. The buffer shaft 152 is pivotally arranged in the pivot member 132 and movably penetrates the buffer seat pipe 151 and includes a first buffer shaft part 1521 and a second buffer shaft part 1522. The first buffer shaft part 1521 is connected to the second buffer shaft part 1522. The buffer cushion 153 is provided for the first buffer shaft part 1521 to penetrate. In the content of the present application, the buffer cushion 153 is a buffer rubber, but is not limited thereto, and can also be other materials, such as polyurethane (PU) or silicone, etc. In this way, through the arrangement of the buffer unit 150, the impact generated when the cushion part 130 is lowered can be effectively alleviated, thereby reducing the impact on the user and reducing the risk of injury. Not only does it enhance the safety of the user, but it also improves the overall comfort.

[0073] The adjustable hydraulic damping unit 160 is pivotally arranged at the pivot seat 110 and located at one side of the damping unit 150, and comprises a hydraulic outer tube 161, a hydraulic inner tube 162 and a hydraulic shaft 163. The hydraulic outer tube 161 is pivotally arranged at the pivot portion 111. The hydraulic inner tube 162 is arranged at one end of the hydraulic outer tube 161 and pivotally arranged at the pivot member 132, and the hydraulic inner tube 162 has a hydraulic limiting surface 1621 which is the tube end surface of the hydraulic inner tube 162 and located inside the hydraulic outer tube 161. The hydraulic shaft 163 is arranged at the hydraulic inner tube 162 and comprises a shaft body 1631 and a shaft head 1632. The shaft body 1631 is connected to the shaft head 1632 and movably arranged at the hydraulic inner tube 162. The shaft head 1632 is arranged inside the hydraulic outer tube 161. By the arrangement of the adjustable hydraulic damping unit 160, the precise damping control can be automatically adjusted according to different load conditions (weight of the user). This can provide the user with higher level of comfort and safety during operation, especially in the application requiring fine control of impact, which can provide stable and persistent damping effect and effectively reduce the risk of impact, thereby significantly reducing the chance of accidents or injuries.

[0074] Please refer to Figure 1 , 3 and 5, wherein Figure 5 is a side view of the chair structure 100 according to Figure 1 at the second position P2. The footrest 140 is stepped by the user to move the cushion 130 back and forth between the first position P1 and the second position P2 through the support rod 120. By the seesaw back and forth action formed by stepping (exerting force) or relaxing (not exerting force) of the foot, the user can be encouraged to make slight movement to promote blood circulation and help burn calories.

[0075] In detail, please refer to Figure 3 , 4A and 4B, when the footrest 140 is not stepped by the user or the stepping force is less than the weight of the user to move the cushion 130 through the support rod 120 at the first position P1, the second damping shaft portion 1522 of the damping shaft 152 abuts against the blocking bottom surface 1512 of the damping seat tube 151, and the damping cushion 153 is driven to be compressed to abut against the blocking top surface 1511 of the damping seat tube 151; at the same time, the shaft body 1631 of the adjustable hydraulic damping unit 160 is embedded in the hydraulic inner tube 162, and the shaft head 1632 is close to the hydraulic limiting surface 1621 of the hydraulic inner tube 162.

[0076] In addition, please refer to Figure 5 , 6A and 6B, wherein Figure 6A is a side view of the chair structure 100 according to Figure 5a partial enlarged view of the adjustable hydraulic damping unit 160 of the chair structure 100; and Figure 6B is a side view of the chair structure 100 according to the first embodiment of the present application. Figure 5 is a partial enlarged view of the damping unit 150 of the chair structure 100. When the footrest 140 is stepped by the user to make the cushion 130 move through the support rod 120 to the second position P2, the second damping shaft portion 1522 of the damping shaft center 152 does not abut against the resisting bottom surface 1512 of the damping seat pipe 151, and the damping cushion 153 is away from the resisting top surface 1511 of the damping seat pipe 151; at the same time, the shaft center body portion 1631 of the adjustable hydraulic damping unit 160 extends out of the hydraulic inner pipe 162, and the shaft center head portion 1632 is away from the hydraulic limiting surface 1621 of the hydraulic inner pipe 162.

[0077] Therefore, through the cooperation of the damping unit 150 and the adjustable hydraulic damping unit 160, when the footrest 140 moves from the second position P2 to the first position P1, the descending speed of the cushion 130 can be effectively slowed down, precise speed control is provided, and sudden impact is avoided. Such a setting not only improves the safety of the user, reduces the risk in the operation process, but also enhances the comfort, and avoids the discomfort caused by the sharp drop.

[0078] Please refer to Figure 1 and Figure 7 , wherein Figure 7 is a side view of the chair structure 100a according to the second embodiment of the present application. In this embodiment, the main structural configuration is the same as that of the first embodiment, but the difference is that the pivot seat 110a is not pivoted with the damping member (the damping unit 150 and the adjustable hydraulic damping unit 160 mentioned in the first embodiment). In addition to the reciprocating movement of the cushion 130a between the first position (not labeled) and the second position (not labeled) through the support rod 120a when the footrest 140a is stepped by the user, the chair structure 100a can also realize the fixed-point balance P3. Specifically, the fixed-point balance P3 refers to the state that the chair structure 100a can be stably kept stationary at a certain specific position through the strength of the core muscle group of the user's abdomen, so as to realize the fixed-point balance P3. The specific position is between the first position and the second position. In the process of moving the cushion 130a, the user not only passively adapts to the change, but also actively adjusts the core muscle group to ensure the body stability and keep the cushion 130a at the required position. Such a balance process emphasizes the body control and coordination of the user, and avoids relying on mechanical or external support, thereby enhancing the flexibility and comfort in the movement.

[0079] In other embodiments, the chair structure is not provided with an adjustable hydraulic cushioning unit, and the remaining components and structural configurations are the same as or similar to those of the first embodiment, and thus will not be repeated. The only difference is that the pivot seat is only pivoted with a cushioning unit.

[0080] In other embodiments, the chair structure is not provided with a cushioning unit, and the remaining components and structural configurations are the same as or similar to those of the first embodiment, and thus will not be repeated. The only difference is that the pivot seat is only pivoted with an adjustable hydraulic cushioning unit.

[0081] In summary, the chair structure of the present application has the following advantages: first, the structure of the present application can encourage users to perform light exercise through the seesaw reciprocating action formed by stepping or placing feet, thereby promoting blood circulation and helping to burn calories; second, the user can effectively change the body's center of gravity through the action of the feet in a sitting position, thereby promoting the activity of abdominal muscles and helping to reduce fat accumulation; and third, not only does it enhance the user's physical activity, but also improves the health level during daily office work or rest, and improves the health risks that may be caused by long-term sitting.

[0082] Although the present application has been disclosed in the above-mentioned embodiments, it is not intended to limit the present application, and any person skilled in the art can make various modifications and decorations without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application shall be defined by the appended claims.
