[0002] Bar stools, known for their stylish, modern, and practical features, have become an indispensable decorative element in numerous venues, such as reception desks and bars. The name "bar stool" derives from their original primary use: bars. However, with the passage of time, their application has expanded far beyond this niche, finding widespread use in karaoke, fast food restaurants, tea restaurants, coffee shops, jewelry stores, cosmetics stores, and more. Even more families are turning to bar stools at home, adding a touch of modernity and style.

[0003] The main feature of a bar stool is its elevated seat, typically between 650 and 900 mm above the ground. This design allows users to use it in a posture somewhere between sitting and standing, making it a good option for those who sit for long periods of time, relieving fatigue. However, while implementing the technical solutions in the embodiments of this application, the inventors discovered that existing bar stools generally suffer from a stiff, uncushioned seating, resulting in poor seating comfort and a negative impact on the user experience.

[0004] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0005] In view of at least one of the above technical problems, the present disclosure provides a bar stool, which mainly solves the technical problems of existing bar stools being stiff to sit on and having poor comfort.

[0006] According to one aspect of the present disclosure, a bar stool is provided, comprising a stool seat, a base, and a stool column for correspondingly connecting the stool seat and the base, the stool column comprising a lower column tube fixedly connected to the base, an upper column tube embedded in the lower column tube along the axial corresponding portion of the stool column, and a buffer spring, one end of which is connected to the end of the upper column tube located in the lower column tube through a bearing and the other end of which is fixed relatively to the base.

[0007] In some embodiments of the present disclosure, the bar stool further includes a footrest portion whose central axis coincides with the central axis of the stool column and is fixedly arranged relative to the base.

[0008] In some embodiments of the present disclosure, the footrest is cylindrical or frustum-shaped.

[0009] In some embodiments of the present disclosure, at least one noise reduction ring is fixed at the outer edge of the upper column tube; the inner edge of the noise reduction ring is fixed at the corresponding position of the outer edge of the upper column tube, and the outer edge of the noise reduction ring is used to fit in contact with the inner edge of the lower column tube.

[0010] In some embodiments of the present disclosure, a surface support for fixedly connecting to the stool surface is provided on the top of the upper column.

[0011] In some embodiments of the present disclosure, a protective cylinder is coaxially nested relatively fixedly outside the upper cylinder, and the length of the protective cylinder is L, then L>L1+H-L2; wherein L1 is the length of the upper cylinder, H is the length of the buffer spring, and L2 is the length of the lower cylinder; the inner diameter of the protective cylinder is greater than the outer diameter of the lower cylinder.

[0012] In some embodiments of the present disclosure, a protective ring is fixedly provided at the outer edge of the bottom of the protective tube.

[0013] In some embodiments of the present disclosure, a fixing gasket for relatively fixed connection with the base is provided at the corresponding end of the buffer spring, and the fixing gasket is welded to the base or connected with corresponding bolts.

[0014] One or more technical solutions provided in the embodiments of this application have at least any of the following technical effects or advantages:

[0015] 1. The elastic deformation characteristics of the buffer spring provide cushioning when the user sits down, improving user comfort.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Unless otherwise specified, the terms "connection" and "coupling" referred to in this application include both direct and indirect connections (couplings).

[0025] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] In order to solve the problem that the existing bar stools have poor sitting comfort due to the lack of cushioning when sitting, this example discloses a bar stool, see Figure 1 The utility model comprises a stool surface 1, a base 2 and a stool column 3 arranged between the stool surface 1 and the base 2.

[0027] Specifically, in this embodiment, the stool surface 1 is disc-shaped so that the user can sit conveniently from all angles. In other embodiments, in order to provide a support point for the sitter, the stool surface in this example includes a backrest to support the sitter's waist and reduce sitting fatigue.

[0028] The base 2 is designed to contact the ground, ensuring the stable placement of the bar stool. In this embodiment, the base 2 is disc-shaped, and a plurality of anti-slip pads are arranged in an array on the end surface of the base 2 that contacts the ground. The friction between the anti-slip pads and the ground improves the stability of the bar stool. Furthermore, the flexibility of the anti-slip pads reduces friction between the base and the ground, thereby reducing any noise generated during transportation or movement.

[0029] The stool column 3 is used to connect the base 2 and the stool surface 1, and at the same time provide reliable support for the stool surface 1. Specifically in this embodiment, the stool column 3 includes a lower column tube and an upper column tube embedded in the lower column tube. Figure 2 The lower column 31 is vertically fixed to the center of the base 2, and the lower column 31 is a hollow cylindrical structure. Figure 3 The upper cylinder 32 is a cylindrical structure with an outer diameter smaller than the inner diameter of the lower cylinder 31, so that the upper cylinder 32 is coaxially embedded in the hollow cavity of the lower cylinder 31 to achieve cushioning when sitting. Figure 3 The upper column 32 is embedded in the lower column 31 and is provided with a buffer spring 4 at its end. One end of the buffer spring 4 abuts against the base 2, and the other end supports the upper column 32. When the user sits down, the upper column 32 is pressed and moves vertically downward, thereby squeezing the buffer spring 4. The buffer spring 4 achieves seating cushioning through its own elastic deformation characteristics, reducing the impact on the user's body when sitting down, thereby improving the comfort of the bar stool. In addition, see Figure 3 In this embodiment, a surface support 5 is welded and fixed to the top of the upper column 32. The contour of the surface support 5 matches the contour of the stool surface 1, and the support and force of the stool surface 1 are achieved through the staggered frame.

[0030] In addition, in this embodiment, see Figure 4 The buffer spring 4 is relatively fixed to the end of the upper column 32 through the bearing 33, thereby achieving buffering while enabling the upper column 32 to rotate with the stool surface 1, further improving the comfort of sitting. In order to achieve the connection and fixation between the buffer spring 4 and the bearing 33, a connecting gasket 34 is set between the buffer spring 4 and the bearing 33 in this example. The two sides of the connecting gasket 34 are respectively welded and fixed to the bearing 33 and the buffer spring 4, thereby achieving a stable connection between the buffer spring 4 and the bearing 33. Considering that the rotation plane of the stool surface is perpendicular to the direction of seating downward pressure, in order to avoid the bearing being damaged and separated due to long-term seating downward pressure, in some other embodiments, the bearing is a planar thrust bearing, wherein the planar thrust bearing includes two relatively rotatable seat plates, the upper seat plate and the inner edge of the upper column, and the lower seat plate and the buffer spring. This ensures that the structural integrity and function of the bearing are still maintained when subjected to the seating downward pressure.

[0031] In addition, in this embodiment, in order to prevent the bar stool structure from separating, the lower end of the buffer spring 4 is relatively fixed to the base. Figure 4 In this embodiment, a fixing washer 35 is welded to the bottom end of the buffer spring 4. A circular through-hole is defined in the center of the fixing washer 35, and a nut 36 is welded to one side of the fixing washer 35, its central axis passing through the center of the circular through-hole. The buffer spring 4 is secured to the base via a threaded connection between a bolt 37 passing through the center of the base and the nut 36 secured to one side of the fixing washer. The diameter of the circular through-hole in the fixing washer is larger than that of the bolt 37, allowing the bolt to pass smoothly through the fixing washer and engage with the nut. To prevent the bolt tip from protruding from the bottom surface of the base and affecting the stability of the bar stool during use, a mounting groove with a depth greater than the thickness of the bolt tip is provided in the base corresponding to the bolt position, ensuring that the bolt tip is fully seated within the groove. This threaded connection facilitates disassembly and assembly in the event of damage and repair of bar stool parts, improving maintenance convenience. In other embodiments, the fixing washer at the end of the buffer spring 4 is directly welded to the base to secure the buffer spring 4 to the base.

[0032] Considering that when the upper column 32 moves axially downward under the pressure of the seat, if the outer wall of the upper column 32 rubs against the inner wall of the lower column 31, a harsh sound will be emitted, thereby affecting the user experience. Figure 3 At least one noise reduction ring 6 is fixedly installed on the outer edge of the upper cylinder 32. The noise reduction ring is made of a wear-resistant material. In this example, two noise reduction rings are provided, and the noise reduction rings are made of nylon plastic. In addition, the inner diameter of the noise reduction ring 6 matches the outer diameter of the upper cylinder 32, and the outer diameter of the noise reduction ring 6 matches the inner diameter of the lower cylinder 31. This ensures that the noise reduction ring 6 is installed on the outer edge of the upper cylinder 32 and prevents direct metal friction between the outer edge of the upper cylinder 32 and the inner edge of the lower cylinder 31. Furthermore, through the non-hard friction between the noise reduction ring and the lower cylinder 31, the abnormal movement noise of the upper cylinder is reduced and eliminated. In this example, lubricating oil is applied to the outer edge of the noise reduction ring to further reduce the friction sound between it and the lower cylinder 31 and reduce friction loss.

[0033] Because the noise reduction ring 6 and the upper column 32 are made of different materials, the noise reduction ring 6 is fixed to the corresponding position on the outer edge of the upper column 32. In this embodiment, a stop ring 61 made of the same material as the stool column is provided on both sides of the noise reduction ring 6. The inner diameter of the stop ring 61 matches the outer diameter of the upper column 21, and the outer diameter is smaller than the outer diameter of the noise reduction ring 6 to prevent failure of the noise reduction ring 6. Therefore, the noise reduction ring 6 is fixed in place by welding the stop ring 61 to the upper column 32.

[0034] See also Figure 3To prevent accidents involving pinching during relative movement between the upper and lower columns 32, 31, and to enhance the aesthetic appeal of the stool, in this embodiment, a protective tube 7 is coaxially nested outside the upper column 31. In this example, the top end of the protective tube 7 is fixedly connected to the face support 5. Assuming the length of the protective tube 7 is L, L > L1 + H - L2, where L1 is the length of the upper column 32, H is the length of the buffer spring 4, and L2 is the length of the lower column 31. This ensures that the length of the protective tube 7 is greater than the length of the lower column exposed when the upper column is embedded within it. Furthermore, the inner diameter of the protective tube 7 is greater than the outer diameter of the lower column 32, thereby preventing obstruction at the intersection of the upper and lower columns and enhancing the aesthetic appeal of the stool. Furthermore, in this embodiment, a protective ring 71 is fixedly secured to the outer edge of the bottom of the protective tube 7. This protects the end of the protective tube 7 and provides a degree of protection, preventing fingers or clothing from being pinched.

[0035] In addition, see Figure 2 In this example, the bar stool further includes a footrest 8 for placing the feet. The footrest 8 is fixedly mounted on the upper surface of the base 2. In this embodiment, the footrest 8 is in the shape of an inverted cone, with its central axis coinciding with the central axis of the stool column. This allows the user's feet to be supported while the user's weight improves the stability of the base 2. In other embodiments, the footrest 8 is in the shape of a column.
