Description

Technical Field

[0001] This utility model relates to a bar stool, and more particularly to an industrial-style bar stool, belonging to the field of bar stool technology. Background Technology

[0002] With the diversified development of modern home and commercial space design, bar stools, as core furniture in leisure and social settings, have received much attention for their functionality, aesthetics, and comfort.

[0003] Traditional bar stools typically feature straight or simple curved designs for the seat and backrest, making it difficult to conform to the natural curves of the hips, waist, and back, potentially leading to localized pressure and reduced comfort. Furthermore, the seats cannot be adjusted to accommodate different sitting postures, limiting their applicability. In addition, the rigid construction and lack of design elements of existing bar stools result in a monotonous overall style and limited suitability for various occasions.

[0004] For example, utility model patent CN213786344U discloses a hard bar stool with height adjustment function. This bar stool includes a seat, a circular tray, a lifting gas spring, and chair legs. The circular tray is fixed to the center of the bottom of the seat by several bolts. The seat is circular. The circular tray consists of an outer circular support, an arched component, a gas spring insertion sleeve, and a hook handle. The lifting gas spring is a constricted lifting gas spring, with its upper end fixed in the gas spring insertion sleeve of the circular tray and its lower end fixed in the gas spring fixing sleeve at the center of the intersection of two sets of chair legs. Circular footrests are fixed to the lower middle positions of the inner sides of the two sets of chair legs. The seat, circular tray, lifting gas spring, gas spring fixing sleeve, chair legs, and circular footrests constitute a hard bar stool. This bar stool differs from ordinary bar stools mainly in its bottom structure, which has the advantage of good stability. However, as mentioned above, this bar stool has a monotonous design style and limited applicability; its structure is rigid and its comfort is low. Utility Model Content

[0005] This invention aims to solve the aforementioned problems by providing a minimalist industrial-style bar stool. Through modular structural design, multi-directional connection constraints, and ergonomic optimization, this invention achieves a breakthrough and balance in assembly efficiency, structural stability, comfort, and functional versatility.

[0006] The technical solution of this utility model to solve the above problems is as follows:

[0007] A minimalist industrial-style bar stool includes a base, a support column based on the base, and a tray disposed at the top of the support column, and a seat disposed based on both the support column and the tray; the seat includes a footrest, a seat body, and a backrest; the seat body is fixed to the tray, and the footrest has a first through hole and a second through hole for the support column to pass through.

[0008] As a preferred embodiment of the above technical solution, the foot rest is a C-shaped structure, with the first through hole located in the upper half of the C-shaped foot rest and the second through hole located in the lower half of the C-shaped foot rest.

[0009] As a preferred embodiment of the above technical solution, it further includes a first collar and a second collar respectively installed in the first through hole and the second through hole; the support column is simultaneously inserted into the first collar and the second collar.

[0010] As a preferred embodiment of the above technical solution, the seat body and the backrest are integrally connected, and the footrest and the seat body are riveted together.

[0011] As a preferred embodiment of the above technical solution, the support column is a gas spring.

[0012] As a preferred embodiment of the above technical solution, the support column includes a fixed part and a telescopic part, the telescopic part being fitted over the fixed part; the telescopic part passes through both the first through hole and the second through hole.

[0013] As a preferred embodiment of the above technical solution, a first docking portion is formed at the upper end of the footrest, and a second docking portion adapted to the first docking portion is provided at the lower end of the seat body.

[0014] As a preferred embodiment of the above technical solution, the first docking part and the second docking part are seamlessly connected.

[0015] As a preferred embodiment of the above technical solution, the first docking part is an L-shaped structure, and the second docking part is an inverted L-shaped structure.

[0016] As a preferred embodiment of the above technical solution, the backrest is C-shaped.

[0017] As a preferred embodiment of the above technical solution, the seat body is S-shaped.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model connects the footrest to the seat body, making the two originally independent components into a whole. This not only optimizes the structural design of the traditional footrest, but also, based on the design and installation of the footrest (the upper end is fixed to the seat body, the lower end is suspended, and the whole is fitted onto the mounting post), the stress point of the footrest when bearing load will change from the welding of the fixed part of the traditional bar stool to a self-locking snap-fit ​​at different positions based on load changes: when the load is different, due to the suspension of the lower end, the inner walls of the first and second through holes will snap-fit ​​with the mounting post at different heights; at the same time, combined with the fixed connection of the upper end to the seat body, the load of the footrest will be transferred to a local area of ​​the seat body, thereby dispersing the load over a larger range, optimizing the load-bearing form of the footrest, and thus solving the problem of stress damage to the footrest of the traditional bar stool with its fixed welded part;

[0020] 2. This utility model connects the footrest to the seat body, making the two originally independent parts into a whole, optimizing the structural design of the traditional footrest, and enabling the footrest, seat body and backrest to form a whole, thereby significantly changing the style of the bar stool and improving its applicability to various occasions.

[0021] 3. The footrest and the main body of the chair seat are seamlessly connected and riveted through the butt joint, which improves the connection between the two and enables rapid assembly;

[0022] 4. Through the cooperation of the first through hole, the second through hole and the first and second collars, the support column is confined within the collar. The collar is made of high-strength plastic material and fits tightly with the support column, and can withstand radial and axial loads. At the same time, the riveting of the footrest and the seat body further enhances the rigidity of the overall structure.

[0023] 5. The C-shaped backrest design conforms to the natural curvature of the human spine, ensuring even pressure distribution on the lumbar and back muscles and reducing fatigue during prolonged use; the S-shaped design of the seat body is customized to the curves of the hips and legs, increasing the contact area and distributing pressure more evenly, avoiding poor blood circulation caused by localized pressure; the L-shaped and reverse L-shaped joints of the footrest seamlessly connect with the seat body, eliminating gaps and improving leg comfort.

[0024] 6. The combination design of C-shaped backrest + S-shaped seat + C-shaped leg rest + modular straight frame maintains the "simple and tough" characteristics of industrial style, while softening the coldness of metal / hard materials with curved elements (C-shaped and S-shaped), making it more visually layered; the hidden design of the ring and joint avoids the sense of clutter, and the overall appearance is more refined.

[0025] 7. The first and second through holes are fitted onto the lifting mechanism, which allows the integral chair seat to remain relatively fixed to the support column during lifting, thereby improving the stability between the two. Attached Figure Description

[0047] The present invention will be further explained below with reference to the accompanying drawings.

[0048] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. Any changes made by those skilled in the art after reading the specification of the present invention, as long as they are within the scope of the claims, will be protected by patent law. Example 1

[0049] A minimalist industrial-style bar stool, such as Figures 1-3 As shown, it consists of four main parts: base 1, support column 2, tray 3, and seat 4. Among them:

[0050] The base 1 is made of stamped metal sheet; it has a square structure and an anti-slip pad on the bottom to ensure quiet movement and stability when the bar stool is placed.

[0051] Support column 2: It is a gas spring structure, including a fixed part 21 (stainless steel tube, diameter 54mm) and a telescopic part 22 (metal tube, diameter 60mm, fitted outside the fixed part). The telescopic part can be adjusted by touching the lever (not shown in the figure); when there is no external force applied to the lever, the telescopic part is fixed.

[0052] Tray 3: A circular metal plate, horizontally fixed to the top of support column 2, used to support chair seat 4.

[0053] Seat 4: Modular design, including footrest 41, seat body 42, and backrest 43. (Example) Figure 3 As shown, the seat body 42 and the backrest 43 are integrally connected, and the footrest 41 is seamlessly connected to the seat body 42 through the first docking part 413 and the second docking part 421 and simultaneously riveted together, making the three into a whole.

[0054] like Figure 3 As shown, the backrest 43 is C-shaped, forming a certain convex arc that conforms to the natural curvature of the human spine, ensuring even pressure distribution on the lumbar and back muscles and reducing fatigue during prolonged use; the seat body 42 has an S-shaped structure, with a customized curvature based on the curves of the hips and legs, increasing the contact area and distributing pressure more evenly, avoiding poor blood circulation caused by localized pressure; the footrest 41 has a C-shaped structure, with a first through hole 411 in the upper half and a second through hole 412 in the lower half. Figure 4 As shown, the upper end of the foot rest 41 is seamlessly connected and riveted through the first docking part 413 and the second docking part 421; the middle part of the foot rest 41 passes through the support column 2; and the lower end of the foot rest 41 is suspended.

[0055] When the foot rest bears a load, it undergoes slight deformation, causing the lower suspended portion to descend.

[0056] The inner wall of the front side of the second through hole 412 acts on the support column 2, and the support column generates a reaction force in the first direction.

[0057] The rear inner wall of the second through hole 412 acts on the support column 2, and the support column generates a second-direction reaction force; under the combined action of the first-direction reaction force and the second-direction reaction force, a self-locking effect is produced.

[0058] Furthermore, the degree of slight deformation varies with different loads, and the self-locking effect remains, but the self-locking position changes slightly. This causes the locking mechanism between the footrest 41 and the support column 41 to change position depending on the load magnitude. Simultaneously, combined with the fixed connection between the upper end and the seat body 42, the load on the footrest 41 is transferred to a localized area of ​​the seat body, thus distributing the load over a larger area and optimizing the load-bearing capacity of the footrest 41.

[0059] More specifically, the first mating part 413 located at the upper end of the footrest 41 has an L-shaped structure, and the second mating part 421 located at the lower end of the seat body 42 has an inverted L-shaped structure. These two parts fit together, allowing for a seamless connection between the footrest 41 and the seat body 42, eliminating gaps and improving the tightness of the connection. Meanwhile, as... Figure 4 As shown, the two are also riveted together to ensure a rigid connection and further enhance their overall integrity.

[0060] Traditional bar stools have independently welded leg rests, where the load is transmitted only through fixed weld points, making them prone to cracking due to stress concentration. In this embodiment, the leg rest 41 is fitted onto the telescopic portion 22 of the support column 2 through a first through hole 411 and a second through hole 412. The load changes with height, and the leg rest 41 engages and locks at different positions on the support column 2. At the same time, the upper end of the leg rest 41 is riveted to the seat body 42, distributing the load to the S-shaped curved surface area of ​​the seat body, avoiding localized stress concentration, and extending service life. Example 2

[0061] The difference from Example 1 is that: Figure 5 As shown, a first collar 51 and a second collar 52 are also installed at the first through hole 411 and the second through hole 412 respectively; the support column 2 is inserted into the first collar 51 and the second collar 52.

[0062] The first ring 51 and the second ring 52 are injection molded from high-strength plastic, and the inner wall is provided with anti-slip texture (to increase the friction with the support column 2).

[0063] The first collar 51 is pressed into the first through hole 411 of the footrest 41 through an interference fit, and the second collar 52 is similarly pressed into the second through hole 412 of the seat body 42. The interference fit between the collar and the through hole is 0.2mm to ensure that the collar and the through hole are tightly fixed.

[0064] The telescopic portion 22 of the support column 2 is inserted into both the first collar 51 and the second collar 52. The collars are tightly fitted to the support column through the anti-slip texture on the inner wall, and can withstand large radial (lateral force) and axial (lifting load) loads.
