Description

Technical Field

[0001] This utility model relates to the field of office chair technology, specifically to a multifunctional integrated sitting and standing office chair. Background Technology

[0002] Office chairs refer to chairs used by general office workers. Depending on the needs of different industries, office chairs are diverse. Currently, common office chairs only include a seat, a backrest at the rear of the seat, armrests on both sides of the seat, and support legs at the bottom of the seat to support the seat. Sitting for a long time will cause back pain and require getting up and moving around. Therefore, office chairs with integrated sitting and standing functions have emerged. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional integrated sitting and standing office chair to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional integrated sitting and standing office chair, comprising: a chair body, a fixed shaft fixedly connected to the chair body, a seat cushion rotatably disposed outside the fixed shaft, a sliding groove formed inside the seat cushion, a backing mechanism slidably disposed within the sliding groove, a first end face gear fixedly sleeved outside the fixed shaft, a second spur gear meshing with the first end face gear, the second spur gear meshing with the second end face gear, the second end face gear being sleeved on the fixed shaft via a bearing, a first spur gear being coaxially fixedly connected to the second end face gear, and the backing mechanism meshing with the first spur gear.

[0005] Furthermore, the supporting mechanism includes a rack, which meshes with a first spur gear, and a limiting plate is fixedly connected to the lower end of the rack, which is slidably disposed in a groove.

[0006] Furthermore, a support pad is fixedly connected to one end of the rack that extends out of the slide groove.

[0007] Furthermore, a spring is provided between the limiting plate and the inner wall of the slide groove.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0024] Please see Figures 1-5 A multifunctional integrated sitting and standing office chair includes: a chair body 1, a fixed shaft 8 fixedly connected to the chair body 1, a seat cushion 2 rotatably disposed outside the fixed shaft 8, a sliding groove 21 opened inside the seat cushion 2, a backing mechanism 3 slidably disposed inside the sliding groove 21, a first end face gear 6 fixedly sleeved outside the fixed shaft 8, a second spur gear 10 meshing with the first end face gear 6, the second spur gear 10 meshing with the second end face gear 7, the second end face gear 7 being sleeved on the fixed shaft 8 through a bearing, a first spur gear 9 being fixedly connected coaxially to the second end face gear 7, the first spur gear 9 being fixedly sleeved outside the second end face gear 7, and the backing mechanism 3 meshing with the first spur gear 9.

[0025] Specifically, this utility model rotates a seat cushion 2 on a fixed shaft 8. When the seat cushion 2 is rotated to a horizontal position, it is used for the user to sit. When the user needs to stand up, the seat cushion 2 automatically rotates, so that the seat cushion 2 is in a state that is close to the initial position. The backrest mechanism 3 slides out of the seat cushion 2 by a certain length, so that the backrest mechanism 3 is located under the user's buttocks for the user to lean on. This realizes the integration of sitting and standing in the office chair, which not only increases the use of the office chair, but also provides the space required to stand in the standing position, greatly improving comfort.

[0026] Furthermore, the supporting mechanism 3 includes a rack 31, which meshes with the first spur gear 9. The lower end of the rack 31 is fixedly connected to a limiting plate 33, which is slidably disposed in the slide groove 21.

[0027] For details, please refer to Figure 3 By setting a limiting plate 33, the sliding stability of the rack 31 in the slide groove 21 is increased.

[0028] Furthermore, a support pad 32 is fixedly connected to one end of the rack 31 that extends out of the slide groove 21.

[0029] For details, please refer to Figure 3 The backrest 32 is a soft cushion that provides a more comfortable sitting experience.

[0030] Furthermore, a spring 331 is provided between the limiting plate 33 and the inner wall of the slide groove 21.

[0031] For details, please refer to Figure 3 One end of the spring 331 is fixedly connected to the limiting plate 33, and the other end of the spring 331 is fixedly connected to the inner wall of the slide groove 21. When the seat cushion 2 is in a horizontal state, the spring 331 is in a compressed state, and the elastic force of the spring 331 tends to push the rack 31 out of the slide groove 21. When the user is not sitting on the seat cushion 2 and pressing down on the seat cushion 2, the seat cushion 2 will push the rack 31 out of the slide groove 21 under the action of the elastic force of the spring 331. Then the rack 31 drives the first spur gear 9 to rotate. Since the first spur gear 9 is fixedly sleeved outside the second end face gear 7, the second end face gear 7 rotates synchronously with the first spur gear 9. The second end face gear 7 drives the first end face gear 6 to rotate through the second spur gear 10, and then drives the entire seat cushion 2 to rotate until the rack 31 is pushed out a specified distance. This distance is related to the maximum distance that the limiting plate 33 can slide in the slide groove 21. The seat cushion 2 follows the rotation to a vertical state, that is, when the rack 31 slides to the maximum distance, the seat cushion 2 rotates 90 degrees.

[0032] Furthermore, a limiting strip 11 is fixedly connected to the chair body 1 to prevent the seat cushion 2 from rotating further.

[0033] Specifically, the limiting strip 11 is located on the side of the chair body 1 closest to the seat cushion 2, preventing the seat cushion 2 from deviating from its horizontal position in the opposite direction. (See reference...) Figure 2 That is, the seat cushion 2 rotates counterclockwise.

[0034] Furthermore, a counterweight is provided inside the end of the seat cushion 2 near the backrest of the chair body 1.

[0035] Specifically, by fixing a counterweight block inside the seat cushion 2, the seat cushion 2 is further promoted to automatically rotate to a vertical state without the application of external force. That is, under the action of gravity, the seat cushion 2 rotates clockwise to achieve a balanced position.

[0036] Furthermore, a locking hole 311 is provided on the rack 31, and a locking screw 4 is threadedly connected to the side of the cushion 2. When the cushion 2 is not subjected to external force, the end of the locking screw 4 can extend into the locking hole 311.

[0037] Specifically, when the seat cushion 2 is in a vertical position, the locking screw 4 is turned so that the end of the locking screw 4 is inserted into the locking hole 311, thereby locking the rack 31 and the seat cushion 2, preventing the rack 31 from moving further in the slide groove 21, and thus preventing the seat cushion 2 from rotating further, ensuring that when the user leans on the backrest 32, the backrest 32 can steadily support the user.

[0038] In this utility model, reference Figures 1 to 5 First, in the vertical position, the rack 31 slides out of the groove 21, allowing the user to lean against the backrest 32 while standing. When the user needs to sit down, the locking screw 4 is unscrewed from the locking hole 311. (Refer to...) Figure 2 Rotating the seat cushion 2 counterclockwise causes the first end face gear 6 to rotate counterclockwise, which in turn drives the second end face gear 7 to drive the first straight gear 9 to rotate clockwise. This engages the rack 31, causing the rack 31 to retract into the slide groove 21, ensuring that the total length of the seat cushion 2 is appropriate when it is in a horizontal state, making it convenient for the user to use.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
