Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to a novel cross-legged chair. Background Art

[0002] Most existing office chairs include a seat and armrests arranged on both sides of the seat. When sitting normally for work, the armrests can support the arms to ensure a comfortable sitting experience. However, when the user is resting, they often hope to cross their legs on the seat. Due to the existence of the armrests, the legs of users with a larger build will interfere with the armrests. Therefore, with the development of society, adjustable office chairs have emerged on the market. These office chairs can be used for sitting or cross-legged, enriching the functions of the seats.

[0003] For example, in the seat patent with the publication number CN112568635, side armrest plates are hinged on the left and right sides of the seat board. When the side armrest plates are in the vertical state, the side armrest plates can be connected to the side connecting plates on the backrest, enabling the side armrest plates to normally support the arms. When the sitter needs to cross their legs, the connection between the side armrest plates and the side connecting plates can be released, and the side armrest plates can be switched to the horizontal state. At this time, the support rods hinged on the side armrest plates can support the side armrest plates in the horizontal state, allowing the sitter to cross their legs. However, such a design has deficiencies.

[0004] When the side armrest plates are in the vertical state, they need to rely on the side connecting plates on the backrest for connection locking or unlocking, and the connection method is the cooperation of a plug and a socket. When the side armrest plates are in the horizontally unfolded state, they need to be supported by the support rods hinged at the lower ends of the side armrest plates. The entire structural design has many components, high costs, cumbersome operations, and the support rods and side connecting plates appear rather obtrusive on the seat, affecting the appearance of the seat.

[0005] The side armrest plates only have two states: horizontally unfolded and vertically upright, and cannot maintain a position when the side armrest plates form an angle with the seat board, making it difficult to adapt to sitters of different body types and affecting the use experience of the seat. Summary of the Invention

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a novel cross-legged chair. By arranging a small-sized gear adjuster between the seat and the side support plate, the side support plate can rotate between the vertical position and the horizontal position and stay at the corresponding positions, enabling the cross-legged chair to have both sitting and multi-gear cross-legged functions. The entire cross-legged chair has a simple structure, a concise appearance, low costs, convenient operation, can adapt to sitters of different body types for sitting or cross-legged, and improves the use experience of the cross-legged chair.

[0007] The technical solution of the utility model is realized as follows:

[0008] A novel cross-legged chair, comprising:

[0009] A seat, configured as a seat support for a cross-legged chair;

[0010] Side support plates, symmetrically arranged on both sides of the seat in the left-right direction;

[0011] A gear regulator, arranged between the side support plate and the seat, including a first rotating member and a second rotating member respectively connected to the seat and the side support plate; the first rotating member and the second rotating member are hinged and can be adjusted in gears, so that the second rotating member can rotate between a vertical position and a horizontal position relative to the first rotating member and stay in the corresponding positions;

[0012] The cross-legged chair has a sitting support mode and a cross-legged support mode. When the cross-legged chair is in the cross-legged support mode, the two side support plates open outwards and stay in the corresponding positions that are horizontal or inclined outwards relative to the seat; when the cross-legged chair switches to the sitting support mode, the two side support plates rotate along the direction close to the inner side of the seat and stay in the vertical position; when the two side support plates in the vertical position rotate along the direction close to the outer side of the seat, the cross-legged chair switches back to the cross-legged support mode.

[0013] Preferably, the gear regulator is inside the side support plate, and the first rotating member and the second rotating member are respectively connected to the upper end surface of the seat and the inner side surface of the side support plate; so that the gear regulator is not exposed outside the cross-legged chair, optimizing the appearance of the cross-legged chair.

[0014] Preferably, the cross-legged chair also has a reclining mode, and each side support plate forms an adjustable angle with the seat. When the cross-legged chair is in the reclining mode, the adjustable angle formed by one side support plate and the seat is greater than the adjustable angle formed by the other side support plate and the seat; so that one of the two side support plates can support the head and the other can support the legs, facilitating the sitter to rest and lie down, and enriching the functions of the cross-legged chair.

[0015] Preferably, when the cross-legged chair is in the reclining mode, the adjustable angle formed by one side support plate and the seat is 180°, and the adjustable angle formed by the other side support plate and the seat is between 90° - 180°; the size range of the adjustable angles formed by the two side support plates and the seat conforms to the habitual posture of the human body lying down, and can make the cross-legged chair form a comfortable lying support effect on the sitter.

[0016] Preferably, the side support plate includes a first sub-plate connected to the second rotating member, and a second sub-plate is rotatably connected to the first sub-plate. When the side support plate is in the vertical position, the second sub-plate in the vertical position can rotate relative to the first sub-plate along the direction close to the inner side of the seat to the horizontal position, so as to reduce the space occupied by the side support plate in the height direction; reducing the packing and transportation volume and cost of the cross-legged chair.

[0017] Preferably, when the second sub-board in the vertical position rotates relative to the first sub-board towards the inner side of the seat to the horizontal position, a receiving area is formed among the seat, the first sub-board, and the second sub-board; a storage box containing other components can be placed in the receiving area, further reducing the transportation cost and occupied space of the cross-legged chair.

[0018] Preferably, when the second sub-board in the vertical position rotates relative to the first sub-board towards the inner side of the seat to the horizontal position, a supporting surface for increasing the supporting area is formed at the upper end of the second sub-board; so that when the sitter is sitting, the arms can be placed on the supporting surface, improving the sitting comfort.

[0019] Preferably, the side support board includes a first sub-board connected to the second rotating member, and a second sub-board is rotatably connected to the upper end of the first sub-board. When the side support board is in the horizontal position, the second sub-board in the horizontal position can rotate relative to the first sub-board towards the inner side of the seat to the vertical position, and two opposite guard surfaces are formed; so that when the sitter is cross-legged, the two guard surfaces can form a blocking effect on the crossed legs, preventing the legs from slipping out of the side support board.

[0020] Preferably, a connecting hinge is provided between the first sub-board and the second sub-board. The connecting hinge includes a first connecting member and a second connecting member respectively connected to the first sub-board and the second sub-board, and the first connecting member and the second connecting member are rotatably connected with damping; so that after the second sub-board rotates, it can stay in the vertical position or the horizontal position without external interference, and the second sub-board will not rotate even under a slight interference force, avoiding affecting the stability of the cross-legged chair during use.

[0021] The beneficial effects of the present utility model adopting the above technical solutions are as follows:

[0022] Compared with the seat in the background art, the gear regulator is smaller in volume, simple in structure, and low in cost, and can realize gear adjustment, enabling the side support board to act as an armrest in the sitting support mode and can rotate outwards to an inclined or horizontal position in the cross-legged mode until the width range between the two side support boards suits the body type of the sitter, which not only simplifies the structure of the cross-legged chair and ensures the appearance of the seat, but also reduces the manufacturing cost of the cross-legged chair, and at the same time enables the cross-legged chair to adapt to sitters of different body types.

[0023] The side support board is set as a split structure of a first sub-board and a second sub-board, enabling the second sub-board in the vertical position to rotate to the horizontal position, reducing the packing volume and transportation cost of the cross-legged chair; and the second sub-board in the horizontal position can form a receiving area with the seat and the first sub-board, and a storage box or other components can be placed in the receiving area, further reducing the packing and transportation cost of the cross-legged chair.

Detailed implementation manners

[0035] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0036] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present utility model is not limited by the specific embodiments disclosed below.

[0037] The specific implementation manner of the present utility model is as follows:

[0038] As Figures 1-10 shown, this embodiment provides a new type of cross-legged chair, including:

[0039] A seat 1, configured as a seat support member of the cross-legged chair; the seat 1 is usually a rigid plate member;

[0040] Side support plates 2, symmetrically arranged on both sides of the seat 1 in the left-right direction;

[0041] A gear adjuster 3, arranged between the side support plate 2 and the seat 1, a first rotating member 31 and a second rotating member 32 respectively connected to the seat 1 and the side support plate 2; the first rotating member 31 and the second rotating member 32 are hinged and can be adjusted in gears, so that the second rotating member 32 can rotate between a vertical position and a horizontal position relative to the first rotating member 31 and stay at the corresponding position;

[0042] The cross-legged chair has a sitting support mode and a cross-legged support mode. When the cross-legged chair is in the cross-legged support mode, the two side support plates 2 open outward and stay at the corresponding positions that are horizontal or inclined outward relative to the seat 1; when the cross-legged chair switches to the sitting support mode, the two side support plates 2 rotate along the direction close to the inner side of the seat 1 and stay at the vertical position; when the two side support plates 2 at the vertical position rotate along the direction close to the outer side of the seat 1, the cross-legged chair switches back to the cross-legged support mode.

[0043] Furthermore, the gear adjuster 3 is an existing mechanism, which is usually arranged between the backrest and the seat of the sofa to realize the angle adjustment between the backrest and the seat. A gear control component 33 is arranged between the first rotating member 31 and the second rotating member 32 to adjust the gears of the second rotating member 32. The gear control component 33 is usually a ratchet and pawl structure. When the side support plate 2 is in the horizontal position, rotate the side support plate 2 along the direction close to the inner side of the seat 1 to the inclined position, and the ratchet and pawl will make the side support plate 2 rotate unidirectionally and stay at the corresponding position. When the side support plate 2 rotates to the vertical position and wants to switch back to the horizontal position, only need to continue to rotate the side support plate 2 towards the inner side of the seat 2 to complete the reverse gear operation and separate the ratchet and pawl structure; the specific structure of the gear control component 33 can refer to the hinge patent with the publication number CN105640106, which will not be elaborated here.

[0044] Furthermore, to ensure the simple and grand appearance of the cross-legged chair, the gear adjuster 3 is located inside the side support plate 2, and the first rotating member 31 and the second rotating member 32 are respectively connected to the upper end surface of the seat 1 and the inner side surface of the side support plate 2. The inner side surface of the side support plate 2 and the upper end surface of the seat 1 are respectively connected with the side support soft package 23 and the seat soft package 11. While enhancing the comfort of the cross-legged chair, the gear adjuster 3 will not be exposed outside the cross-legged chair, optimizing the appearance of the cross-legged chair.

[0045] Furthermore, as Figure 9 shown, due to the setting of the gear adjuster 3, the cross-legged chair also has a reclining mode. Specifically, each side support plate 2 forms an adjustment angle A with the seat 1. When the cross-legged chair is in the reclining mode, the adjustment angle A formed by one side support plate 2 and the seat 1 is greater than the adjustment angle A formed by the other side support plate 2 and the seat 1; a structure with one adjustment angle A large and one adjustment angle A small is formed. The user can lie on the corresponding two side support plates 2. One side support plate 2 can support the head, and the other side support plate 2 can support the legs. The seat 1 can support the body, facilitating the sitter to rest and lie down, and enriching the functions of the cross-legged chair.

[0046] Furthermore, to conform to the habits and postures of the human body lying down, when the cross-legged chair is in the reclining mode, the adjustment angle A formed by one side support plate 2 and the seat 1 is 180°, so that the legs of the sitter can be laid flat, and the adjustment angle A formed by the other side support plate 2 and the seat 1 is between 90° - 180°, which is convenient for supporting the upper body of the sitter. The size range of the adjustment angle A formed by the two side support plates 2 and the seat 1 conforms to the habitual posture of the human body lying down, and the cross-legged chair can form a comfortable lying support effect on the sitter.

[0047] Furthermore, the seat 1 and the side support plates 2 of the cross-legged chair in this embodiment need to be packed separately during transportation. However, as Figure 6 shown, if the integral side support soft package 23 is directly connected to the inner side surface of the side support plate 2, when the side support plate 2 rotates towards the seat 1, the side support soft package 23 will have extrusion interference with the seat soft package 11 on the upper end surface of the seat 1, and it is difficult to effectively reduce the occupied space of the package. After a long time of transportation, indentations will be generated on the seat soft package 11 and the side support soft package 23, affecting the appearance of the cross-legged chair.

[0048] Specifically, as Figures 7-8As shown in the figure, in order to effectively reduce the transportation volume and cost, in this embodiment, the side support plate 2 includes a first sub-plate 21 connected to the second rotating member 32. A second sub-plate 22 is rotatably connected to the first sub-plate 21. The inner sides of the first sub-plate 21 and the second sub-plate 22 are respectively connected to a first sub-pack 24 and a second sub-pack 25. When the side support plate 2 is in the vertical position, the second sub-plate 22 in the vertical position can rotate relative to the first sub-plate 21 to the horizontal position along the direction close to the inner side of the seat 1, so as to reduce the space occupied by the side support plate 2 in the height direction; reduce the packing and transportation volume and cost of the cross-legged chair; at the same time, after the second sub-pack 25 is flipped to the horizontal position, it will not cause extrusion interference with the first sub-pack 24 or the seat soft pack 11, ensuring that the appearance of the cross-legged chair is not affected; and when the second sub-plate 22 in the vertical position rotates relative to the first sub-plate 21 to the horizontal position along the direction close to the inner side of the seat 1, a receiving area 26 is formed between the seat 1, the first sub-plate 21, and the second sub-plate 22; the receiving area 26 can place a storage box 5 containing other parts or parts such as chair legs, further reducing the transportation cost and occupied space of the cross-legged chair.

[0049] Furthermore, the rotational design of the first sub-plate 21 and the second sub-plate 22 can also improve the sitting comfort. When the cross-legged chair is in the sitting support mode, the second sub-plate 22 in the vertical position rotates relative to the first sub-plate 21 to the horizontal position along the direction close to the inner side of the seat 1, and a supporting surface 22a for increasing the supporting area is formed at the upper end of the second sub-plate 22; so that when the sitter is sitting, the arm can be placed on the supporting surface 22a, improving the sitting comfort.

[0050] Furthermore, as Figure 10 shown in the figure, when the cross-legged chair is in the cross-legged support mode, the rotational design of the first sub-plate 21 and the second sub-plate 22 can also form a blocking effect on the legs of the sitter. Specifically, when the side support plate 2 is in the horizontal position, the second sub-plate 22 in the horizontal position can rotate relative to the first sub-plate 21 to the vertical position along the direction close to the inner side of the seat 1, and two opposite protecting surfaces 22b are formed; so that when the sitter is cross-legged, the two protecting surfaces 22b can form a blocking effect on the crossed legs, preventing the legs from slipping out of the side support plate 2.

[0051] Further, in order to allow the first partition 21 and the second partition 22 to rotate relative to each other, a connecting hinge 4 is provided between the first partition 21 and the second partition 22, and the connecting hinge 4 includes a first connecting member 41 and a second connecting member 42 respectively connected to the first partition 21 and the second partition 22, and in order to keep the second partition 22 rotated in place stable and not easily deflected; the first connecting member 41 and the second connecting member 42 are connected in a damped rotational connection; that is, the first partition 21 and the second partition 22 are connected by a damping hinge, and the damping hinge is an existing hinge. When hinged, a friction bushing is usually provided at the rotational connection position of the first connecting member 41 and the second connecting member 42 to provide a damping friction force after the rotation for the second connecting member 42, which can be purchased on major shopping websites, and the specific structure is not repeated; the damped rotational connection allows the second partition 42 to stay in a vertical position or a horizontal position without external interference after the rotation, so that the second partition 42 will not rotate even if it is slightly disturbed, thereby avoiding affecting the stability of the cross-legged chair when in use.

[0052] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
