Description

Technical Field

[0001] This invention relates to the field of bar stool technology, and more particularly to a folding high bar stool. Background Technology

[0002] Originally used primarily in bars, bar stools are now increasingly common in various establishments, including hot pot restaurants, fast food restaurants, tea restaurants, cafes, jewelry stores, and cosmetics stores. Furthermore, more and more people are choosing to place a few bar stools in their homes to enhance their modern ambiance.

[0003] Most existing bar stools are fixed structures. A Chinese utility model patent with publication number CN223627184U discloses a bar stool with good stability, including a circular plate. The bottom of the circular plate is evenly provided with several legs, and the legs are provided with footrests. The circular plate is provided with an elastic device to improve sitting comfort. The top of the elastic device is provided with a circular plate, and the circular plate is provided with an adjustment device to adjust the height of the chair. A connecting rod is hinged to the adjustment device, and the other end of the connecting rod is hinged to a semi-enclosed seat surface. The adjustment device includes a circular cavity on the circular plate and several sliding grooves evenly arranged around the circular cavity. A slider is provided in the sliding groove. A first bevel gear and a second bevel gear meshing with the first bevel gear are provided in the circular cavity.

[0004] The bar stools mentioned above have a fixed shape, making them inconvenient to store and move.

[0005] In addition, existing folding chairs have two support frames that are directly hinged together. When the two support frames rotate and fold relative to each other, the two support frames cannot fit together effectively due to the limitation of the hinge point, resulting in a limited folding effect. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a folding high bar stool, wherein the front and rear support frames of the bar stool can be folded together, reducing the overall storage volume of the bar stool, facilitating transportation and storage, and realizing the lateral folding of the bar stool, resulting in a narrow width and good storage effect after folding.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A folding high bar stool includes a bar stool body, characterized in that: the bar stool body includes a front support frame and a rear support frame spaced behind the front support frame, a seat plate is detachably provided between the upper end of the front support frame and the upper part of the rear support frame, and the portion of the rear support frame extending out of the seat plate is tilted backward to form a backrest frame.

[0009] A folding mechanism is provided between the two sides of the front support frame and the rear support frame; the folding mechanism includes a first fork, a second fork, and two fixed rods. The two fixed rods are respectively fixed to the inner ends of the front support frame and the rear support frame. The middle part of the first fork is hinged to the middle part of the second fork, and the upper and lower ends of the first fork and the second fork are respectively hinged to the upper and lower ends of the two fixed rods.

[0010] The lower part of the first and second forks is provided with sliding holes, and the lower part of the fixed rod is provided with a connecting pin that extends into the sliding holes. When the first and second forks are unfolded relative to each other, the connecting pin is at the bottom of the sliding holes. Under the action of external force, the first and second forks can rotate along their middle hinge point, and the lower parts of the first and second forks swing relative to each other. The sliding holes slide downward relative to the connecting pin, so that the fixed rods on both sides can move horizontally closer to each other. In this way, the front support frame and the rear support frame can move horizontally closer to each other.

[0011] A locking assembly is provided between the first fork and the second fork. The locking assembly can keep the first fork and the second fork in an unfolded state. The locking assembly can be unlocked under the action of external force, allowing the first fork and the second fork to rotate and fold relative to each other.

[0012] Preferably, the locking assembly includes a locking plate and an elastic element; the upper side wall of the first fork is provided with a protrusion, the protrusion is provided with a first connecting hole, the locking plate is provided below the protrusion, one end of the locking plate is hinged to the second fork, and the other end of the locking plate forms a slot that abuts against the connecting pin; the upper part of the locking plate is folded to form a hanging edge, the hanging edge is located directly below the protrusion, the hanging edge is provided with a second connecting hole, and the elastic element is longitudinally arranged between the first fork and the second fork, the upper end of the elastic element is connected to the first connecting hole, and the lower end of the elastic element is connected to the second connecting hole;

[0013] When the first fork and the second fork are unfolded relative to each other, the elastic element moves outward and pulls the locking plate to swing outward, and the latch abuts against the adjacent connecting pin. In this way, the first fork and the second fork are kept in the unfolded state by the locking plate and the elastic element.

[0014] Preferably, the locking plate has a paddle extending outward from its end, and a lever is fixed between the two paddles.

[0015] Preferably, the elastic element is a tension spring.

[0016] Preferably, the lower parts of the first and second forks are bent into a V-shape, thereby making the sliding hole V-shaped. The sliding hole includes a first sliding section with its upper end raised upward, and a second sliding section that communicates with the first sliding section and has its lower end raised upward. In this way, the first and second forks rotate and fold relative to each other, and the connecting pin moves obliquely upward along the first sliding section and then obliquely forward along the second sliding section.

[0017] Preferably, the lower parts of the first and second forks are bent inward along the bending point, so that a clearance is formed on the lower front side of the first and second forks.

[0018] Preferably, the fixing rod includes a longitudinally arranged main body, flanges formed on both sides of the main body, and connecting edges extending upward along the outer ends of the flanges. The main body is provided with a plurality of fixing holes. The upper parts of the first fork and the second fork are hinged to the upper connecting edge, and the connecting pin is installed on the lower connecting edge through the sliding hole.

[0019] Preferably, the front support frame and the rear support frame are made of square tubes or round tubes; the front support frame includes two symmetrically arranged front columns, a foot tube connected between the front ends of the middle of the two front columns, and a first connecting rod connected between the upper parts of the two front columns.

[0020] The rear support frame includes two symmetrically arranged rear columns and a support tube integrally formed on the upper end of the two rear columns.

[0021] The backrest frame is formed by connecting the lower part of the two rear columns and the upper part of the two rear columns. The portion of the two rear columns above the third connecting rod and the support tube are inclined backward. The first connecting rod and the third connecting rod are at the same height. The seat plate is horizontally fixedly installed on the upper end of the first connecting rod and the third connecting rod.

[0022] Preferably, the bottom front and rear sides of the seat plate are fixedly provided with multiple pipe clamps, and the seat plate is detachably installed on the first connecting rod and the third connecting rod through the multiple pipe clamps; the pipe clamps are arranged laterally, and the inner side of the pipe clamp forms a groove that matches the cross section of the first connecting rod and the third connecting rod, with openings on the left and right sides and the bottom of the groove; the front and rear sides of the lower end of the pipe clamp are configured as guide slopes, and the inner edge of the guide slopes extends into the groove to form hooks that hook the lower edges of the first connecting rod and the third connecting rod;

[0023] When the front support frame and the rear support frame move horizontally closer to each other, the seat plate is vertically positioned above the foot pedal tube, and the upper tube clamp of the seat plate is vertically arranged and snapped onto the front end of the first connecting rod.

[0024] Preferably, the upper part of the bar stool is detachably provided with a bar stool cover, the upper rear side of which forms a backrest cover that fits the backrest frame, and the lower part of the bar stool cover forms a square outer cover with a bottom opening, the lower end of which is flush with the upper end of the foot pedal tube.

[0025] The present invention adopts the above technical solution and has the following technical effects:

[0026] ① The front and rear support frames of the bar stool are connected by a folding mechanism. The folding mechanism consists of a first fork, a second fork, and a fixed rod. Through the hinge in the middle of the two forks and the staggered hinge between the upper and lower ends of the two forks and the fixed rods on both sides, a scissor telescopic structure is formed. Under the action of external force, the two forks rotate around the hinge point, the lower part of the two forks swings, and the sliding hole slides downward relative to the connecting pin, so that the fixed rods on both sides move horizontally together. In this way, the front and rear support frames of the entire bar stool move horizontally together. This lateral folding method makes the overall thickness of the folded bar stool smaller, realizing the reliability of the folding function, the convenience of operation, and the structural stability of the bar stool in use. It significantly reduces the storage volume and makes it easy to stack or move in small spaces (such as restaurants, classrooms, and conference rooms).

[0027] ② The locking component in the folding mechanism is located between the first and second forks. In the unfolded state, it maintains the relative angle of the forks, preventing accidental folding due to accidental contact or external force. Specifically, the locking component includes a tension spring and a locking plate. When the first and second forks are unfolded to the desired position, the tension spring moves outward and pulls the locking plate outward. The latch at the end of the locking plate automatically engages with the adjacent connecting pin, achieving mechanical self-locking. This process requires no additional user intervention; locking is completed simultaneously with unfolding, forming an automatic locking, reliable linkage, and compact structure, making operation more convenient. This design balances safety and ease of operation, making it particularly suitable for public or commercial locations where people frequently get up and sit down.

[0028] ③ The sliding hole is V-shaped, which includes a first sliding section and a second sliding section. The connecting pin moves along the first sliding section and then slides along the second sliding section. This sliding hole design not only plays a guiding role, but also automatically compensates for the displacement changes caused by the rotation of the fork during the folding process. This keeps the front and rear support frames moving in parallel during the closing process, avoiding jamming or tilting, improving the smoothness of the folding operation and the durability of the structure. The folding action is stable and the structure has good self-adaptability.

[0029] ④ The locking plate and the connecting pin are locked by abutment. When folding is required, simply overcome the tension of the spring and move the locking plate to disengage the latch from the connecting pin to unlock. The two locking plates are connected by a lever. Simply swing the lever forward to unlock. The unlocking action is simple and the folding efficiency is high.

[0030] ⑤ The seat can be detached and installed on the bar stool using clips (buckles), making disassembly and assembly very convenient; when the bar stool is folded, the seat can be removed and vertically clipped onto the front support frame, improving the neatness and stability after storage.

[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more, unless explicitly defined otherwise.

[0049] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] like Figures 1-15 The folding high bar stool shown includes a bar stool body, which includes a front support frame 1 and a rear support frame 2 spaced behind the front support frame 1. A seat plate 3 is detachably provided between the upper end of the front support frame 1 and the upper part of the rear support frame 2. The part of the rear support frame 2 that extends out of the seat plate 3 tilts backward to form a backrest frame 4.

[0052] A folding mechanism is provided between the two sides of the front support frame 1 and the rear support frame 2. The folding mechanism includes a first fork 5, a second fork 6 and two fixed rods 7. The two fixed rods 7 are respectively fixed to the inner ends of the front support frame 1 and the rear support frame 2. The middle part of the first fork 5 is hinged to the middle part of the second fork 6. The upper and lower ends of the first fork 5 and the second fork 6 are respectively hinged to the upper and lower ends of the two fixed rods 7 in an alternating manner.

[0053] The lower part of the first fork 5 and the second fork 6 is provided with a sliding hole 8, and the lower part of the fixed rod 7 is provided with a connecting pin 9 that extends into the sliding hole 8. When the first fork 5 and the second fork 6 are unfolded relative to each other, the connecting pin 9 is at the bottom of the sliding hole 8. Under the action of external force, the first fork 5 and the second fork 6 can rotate along their middle hinge point. The lower parts of the first fork 5 and the second fork 6 swing relative to each other, and the sliding hole 8 slides downward relative to the connecting pin 9, so that the fixed rods 7 on both sides can move relatively horizontally and approach each other. In this way, the front support frame 1 and the rear support frame 2 can move relatively horizontally and approach each other.

[0054] A locking assembly is provided between the first fork 5 and the second fork 6. The locking assembly can keep the first fork 5 and the second fork 6 in an unfolded state. The locking assembly can be unlocked under the action of external force, allowing the first fork 5 and the second fork 6 to rotate and fold relative to each other.

[0055] In the above technical solution, the front and rear support frames of the bar stool are connected on both sides by a folding mechanism. The folding mechanism consists of a first fork, a second fork, and fixed rods. Through the hinge in the middle of the two forks and the staggered hinge between the upper and lower ends of the two forks and the fixed rods on both sides, a scissor telescopic structure is formed. Under the action of external force, the two forks rotate around the hinge point, the lower part of the two forks swings, and the sliding hole slides downward relative to the connecting pin, so that the fixed rods on both sides move horizontally together. In this way, the front and rear support frames of the entire bar stool move horizontally together. This lateral folding method makes the overall thickness of the folded bar stool smaller, realizing the reliability of the folding function, the convenience of operation, and the structural stability of the bar stool in use. It significantly reduces the storage volume and makes it easy to stack or transport in small spaces (such as restaurants, classrooms, and conference rooms).

[0056] A locking mechanism is located between the first and second forks, maintaining the relative angle of the forks in the unfolded state to prevent accidental folding due to accidental contact or external force. Simultaneously, the locking mechanism can be unlocked under external force without affecting normal folding operation. This design balances safety and ease of use, making it particularly suitable for public or commercial spaces where people frequently get up and sit down.

[0057] like Figures 6-10As shown, the locking assembly includes a locking plate 10 and an elastic element; the upper side wall of the first fork 5 is provided with a protrusion 11, the protrusion 11 is provided with a first connecting hole 12, the locking plate 10 is provided below the protrusion 11, one end of the locking plate 10 is hinged to the second fork 6, and the other end of the locking plate 10 forms a bayonet 13 that abuts against the connecting pin 9; the upper part of the locking plate 10 is folded to form a hanging edge 14, the hanging edge 14 is located directly below the protrusion 11, the hanging edge 14 is provided with a second connecting hole 15, the elastic element is longitudinally arranged between the first fork 5 and the second fork 6, the upper end of the elastic element is connected to the first connecting hole 12, and the lower end of the elastic element is connected to the second connecting hole 15;

[0058] When the first fork 5 and the second fork 6 are unfolded relative to each other, the elastic element moves outward and pulls the locking plate 10 to swing outward. The latch 13 abuts against the adjacent connecting pin 9, so that the first fork 5 and the second fork 6 are kept in the unfolded state by the locking plate 10 and the elastic element.

[0059] In the above technical solution, the locking assembly includes an elastic element and a locking plate. When the first and second forks are unfolded to the working position, the elastic element moves outward and pulls the locking plate outward. The latch at the end of the locking plate automatically engages with the adjacent connecting pin, achieving mechanical self-locking. This process requires no additional user operation; locking is completed simultaneously with unfolding, forming an automatic locking, reliable linkage, and compact structure locking mechanism that is more convenient to operate. When folding is required, simply overcome the tension of the spring and move the locking plate to disengage the latch from the connecting pin to unlock. The two locking plates are connected by a lever; simply swing the lever forward to unlock. The unlocking action is simple, and the folding efficiency is high.

[0060] like Figures 4-7 As shown, a lever 16 extends outward from the end of the locking plate 10, and a lever 17 is fixedly provided between the two levers 16. In this technical solution, the lever is set on the locking plate and the two locking plates are linked by the lever to achieve synchronous unlocking, which improves the convenience and consistency of operation and avoids jamming or safety hazards caused by inconsistent locking states on both sides.

[0061] Furthermore, the elastic element is a tension spring 18. In this technical solution, using a tension spring as the elastic element results in a simple structure, low cost, and good reset and holding force, ensuring stable locking of the locking assembly in the deployed state.

[0062] like Figures 6-9As shown, the lower parts of the first fork 5 and the second fork 6 are bent into a V-shape, thus making the sliding hole 8 V-shaped. The sliding hole 8 includes a first sliding section 19 with its upper end raised upwards, and a second sliding section 20 that communicates with the first sliding section 19 and has its lower end raised upwards. In this way, the first fork 5 and the second fork 6 rotate relative to each other and fold. The connecting pin 9 moves obliquely upwards along the first sliding section 19 and then obliquely forwards along the second sliding section 20. In this technical solution, the sliding hole is V-shaped, that is, it includes a first sliding section and a second sliding section. The connecting pin moves along the first sliding section and then slides along the second sliding section. The sliding hole designed in this way not only plays a guiding role, but also automatically compensates for the displacement changes caused by the rotation of the fork during the folding process, so that the front and rear support frames keep moving in parallel during the closing process, avoiding jamming or deflection, improving the smoothness of the folding operation and the durability of the structure, the folding action is stable, and the structure has good self-adaptability.

[0063] Furthermore, the lower parts of the first fork 5 and the second fork 6 are bent inward along the bending point, thus forming an avoidance opening 21 on the lower front side of the first fork 5 and the second fork 6. In this technical solution, the lower part of the fork is bent inward to form an avoidance opening, which avoids interference with other components (especially with the locking plate) during the folding process, improves the compactness of the folding, and reduces the overall thickness after folding.

[0064] Furthermore, the fixing rod 7 includes a longitudinally arranged main body 22, flanges 23 formed on both sides of the main body 22, and connecting edges 24 extending upward along the outer ends of the flanges 23. The main body 22 is provided with a plurality of fixing holes 25. The upper parts of the first fork 5 and the second fork 6 are hinged to the upper connecting edge 24, and the connecting pin 9 passes through the sliding hole 8 and is installed on the lower connecting edge 24. In this technical solution, the fixing rod adopts a flange and connecting edge structure, which enhances the overall strength and provides a reliable mounting position for the fork hinge and sliding pin, preventing interference. The structure is stable and easy to assemble and position.

[0065] Furthermore, the front support frame 1 and the rear support frame 2 are made of square or round tubes; the front support frame 1 includes two symmetrically arranged front columns 26, a foot pedal tube 27 connected between the front ends of the two front columns 26, and a first connecting rod 28 connected between the upper parts of the two front columns 26.

[0066] The rear support frame 2 includes two symmetrically arranged rear columns 29, a support tube 30 integrally formed on the upper end of the two rear columns 29, a second connecting rod 31 connected between the lower parts of the two rear columns 29, and a third connecting rod 32 connected between the upper parts of the two rear columns 29; the portion of the two rear columns 29 above the third connecting rod 32 and the support tube 30 tilt backward to form the backrest frame 4, the first connecting rod 28 and the third connecting rod 32 have the same height, and the seat plate 3 is horizontally fixedly installed on the upper end of the first connecting rod 28 and the third connecting rod 32.

[0067] In the above technical solution, the front and rear support frames of the bar stool can adopt a square tube or round tube structure, such as... Figures 13-15 The bar stools are made of round tubing, but other effective tubing shapes can also be used. The footrest tubes enhance the structural strength between the front uprights and provide a comfortable place for the user's feet. The second connecting rod improves the structural strength between the rear uprights. The backrest frame is designed to tilt backward, conforming to ergonomics and enhancing seating comfort. The first and third connecting rods improve the overall rigidity of the bar stool while facilitating seat installation.

[0068] like Figure 11 and 12 As shown, multiple pipe clamps 33 are fixedly provided on the front and rear sides of the bottom of the seat plate 3. The seat plate 3 can be detachably installed on the first connecting rod 28 and the third connecting rod 32 through the multiple pipe clamps 33. The pipe clamps 33 are arranged laterally, and the inner side of the pipe clamps 33 forms a groove 34 that matches the cross section of the first connecting rod 28 and the third connecting rod 32. The groove 34 is open on the left and right sides and the bottom. The front and rear sides of the lower end of the pipe clamps 33 are configured as guide slopes 35. The inner edge of the guide slopes 35 extends into the groove 34 to form hooks 36 that hook the lower edge of the first connecting rod 28 and the third connecting rod 32.

[0069] When the front support frame 1 and the rear support frame 2 move horizontally closer to each other, the seat plate 3 is vertically positioned above the foot pedal tube 27, and the upper tube clamp 33 of the seat plate 3 is vertically arranged and snapped onto the front end of the first connecting rod 28.

[0070] In the above technical solution, the seat plate is detachably installed on the first and third connecting rods using multiple pipe clamps. The pipe clamps have slots on their inner sides. When installing the seat plate, the pipe clamps are aligned with the first and third connecting rods and pressed down. The guide slope contacts the upper ends of the first and third connecting rods, opening the slots and locking the plate onto the two connecting rods. The bottom hooks of the pipe clamps hook the lower ends of the two connecting rods to prevent vertical movement. When removing the seat plate, a slight upward force disengages the hooks, allowing the seat plate to be easily lifted. Furthermore, after the front and rear support frames are folded, the seat plate can be vertically secured to the first connecting rod using the upper pipe clamps, facilitating seat plate storage and improving the neatness and stability of the bar stool after storage.

[0071] like Figure 1 and 2 As shown, the upper part of the bar stool is detachably equipped with a bar stool cover 37. The upper rear side of the bar stool cover 37 forms a backrest cover 38 that fits the backrest frame 4. The lower part of the bar stool cover 37 forms a square outer cover 39 with an opening at the bottom. The lower end of the outer cover 39 is flush with the upper end of the footrest tube 27. In this technical solution, the bar stool cover can be directly removed and put on the bar stool, which is convenient for disassembly and assembly. After the cover is installed, it can cover the internal folding mechanism to prevent the safety hazard of pinching hands, while improving the comfort and aesthetics of the bar stool.
