Description

Technical Field

[0001] This utility model relates to the field of seating, and in particular to a cross-legged chair with easily adjustable armrests. Background Technology

[0002] To broaden the scope of use and functionality, some chairs on the market typically feature flip-up armrests on both sides of the seat. This allows the armrests to rotate left and right, opening outwards or retracting inwards to a predetermined position. The armrests in such chairs can remain upright, allowing the user to sit normally and support their arms. Alternatively, the armrests can be flipped outwards to a tilted or horizontal position, increasing the seating space between the armrests and the seat, allowing the user to sit cross-legged.

[0003] For example, in the seat patent with publication number CN112568635, there is a seat board and rotatable side armrests on both sides of the seat board. When the side armrests are in an upright position, they are kept stable by the cooperation of the insert post and the insert post hole. When the side armrests are flipped outward to a horizontal position, they are supported by the support rod and kept stable. This kind of seat can only adjust the armrests between upright and horizontal, and cannot keep the armrests stable when tilted.

[0004] For example, in the chair patent with announcement number CN202653628, the armrest frame and the base are connected by an angle adjuster. The angle adjuster can generate a locking force, so that the armrest frame can only rotate inward and not outward. When it is necessary to rotate the armrest frame outward, the armrest frame must be rotated to an upright position and then pressed inward to return the armrest frame to its initial position. This type of angle adjuster is common in sofas. Its structural principle is a ratchet one-way locking principle. For the specific structure, please refer to the hinge patent with announcement number CN105640106, which will not be elaborated here. However, the armrests of this chair can only be gradually adjusted from a horizontal position to an upright position. When the armrest is in a tilted position and it is necessary to rotate the armrest outward, the armrest must be returned to an upright position and then pressed inward. It is not possible to rotate the armrest directly outward. The operator cannot easily adjust the armrest to the predetermined position according to their own needs, which still affects the user experience of the chair. Summary of the Invention

[0005] This utility model provides a cross-legged chair with easily adjustable armrests. By setting a control component to control the engagement or disengagement of the locking piece with the corresponding stop slot, the user can flip the armrests outward or inward according to their own needs and keep the armrests stably in the predetermined position, thereby improving the ease of operation of the armrest control and the user experience of the chair.

[0006] The technical solution of this utility model is implemented as follows: A cross-legged chair with adjustable armrests includes a seat and armrests on the left and right sides of the seat. The seat and armrests are respectively provided with a fixed seat and a rotating seat. The rotating seat and the fixed seat are rotatably connected via a pivot, allowing the armrests to rotate in the left and right directions. The fixed seat has multiple circumferentially spaced stop slots, and the rotating seat has a latching component that can engage or disengage from the corresponding stop slot. The armrests are equipped with a control component, which includes an elastic element and a linkage lever rotatably connected to the armrests. The elastic element can act and force the latching component to always tend to engage with the stop slot. The linkage lever and the latching component are connected by a flexible pull wire. Under the action of external force, the linkage lever swings and pulls the flexible cable, so that the linkage latching part disengages from the stop groove and causes the elastic element to deform. At this time, the handrail is unlocked and can be flipped in the left and right directions. When the external force is removed, the elastic element resets and forces the latching part to snap into the corresponding stop groove to lock the handrail in the predetermined position.

[0007] Preferably, the fixed seat includes two fixed supports arranged symmetrically front to back, each fixed support having a stop groove spaced apart along the circumferential direction; the rotating seat includes rotating supports corresponding one-to-one with the fixed supports, each rotating support having a strip groove, and the locking element is a locking pin that slides synchronously in the two strip grooves; the symmetrical front to back arrangement design forms two stop locking points between the fixed seat and the rotating seat in the front-back direction, ensuring the support stability of the handrail after the locking element engages with the stop groove.

[0008] Preferably, the elastic element is a tension spring disposed between the rotating shaft and the snap-fit ​​element or between the fixed seat and the snap-fit ​​element; or, the elastic element is a compression spring disposed between the rotating seat and the snap-fit ​​element or between the handrail and the snap-fit ​​element.

[0009] Preferably, the linkage lever is connected to a control lever that is easy to operate by hand; one end of the control lever extends beyond the handrail.

[0010] Preferably, the control lever is rotatably connected to the linkage swing arm, and the control lever is slidably connected to the handrail; one end of the control lever protrudes outside the handrail and forms an operating part that is easy for the hand to press; so that the operator can control the locking part to separate from the stop groove simply by pressing the operating part.

[0011] Preferably, the handrail is equipped with a mechanical spring that acts on the control lever or linkage lever; when the handrail is unlocked, the linkage lever swings and causes the mechanical spring to deform and store elastic force; when the handrail is locked, the mechanical spring releases the elastic force and causes the linkage lever and control lever to reset.

[0012] Preferably, the mechanical spring is a tension spring or a compression spring; the compression spring or tension spring is disposed between the handrail and the control rod; or, the compression spring or tension spring is disposed between the handrail and the linkage lever.

[0013] Preferably, the linkage lever is L-shaped, comprising a vertical lever and a horizontal lever, with the horizontal lever connected to a flexible pull wire; and the rotational connection position between the linkage lever and the handrail is located at the junction of the horizontal lever and the vertical lever.

[0014] Preferably, a guide wheel is rotatably connected to the handrail, and the outer wall of the guide wheel is provided with an annular guide groove. A flexible pull wire is wound in the guide groove to guide the flexible pull wire to pull the snap-fit ​​component in a predetermined direction.

[0015] Preferably, the handrail is a hollow shell structure; the shell structure of the handrail is lighter and also makes it easier to provide installation space for the various components in the control assembly.

[0016] Preferably, the handrail is provided with an open receiving groove at the top and bottom, and the rotating seat and the fixed seat are located in the receiving groove and do not protrude from the outer surface of the handrail; thus reducing the abruptness of the fixed seat and the rotating seat at the handrail.

[0017] Preferably, the control lever and the linkage lever are fixedly connected; one end of the control lever protrudes from the handrail and forms an operating part that is easy to operate by hand; so that the operator can control the locking part to separate from the stop groove simply by operating the operating part.

[0018] The beneficial effects of this utility model, which adopts the above technical solution, are as follows: This utility model provides a position adjustment structure consisting of a snap-fit ​​component and a position groove between the fixed seat and the rotating seat. The snap-fit ​​component is then controlled by a control component to separate or reposition with the corresponding position groove, allowing the armrest to be flipped inward or outward to a predetermined position according to the user's needs. The position is locked by the snap-fit ​​component engaging with the corresponding position groove, making it easier to adjust the seating space between the two armrests and the seat, thus improving the ease of operation of the armrest control and the user experience of the seat.

[0019] The fixed supports and rotating supports are arranged symmetrically front and back. The corresponding locking parts can be simultaneously engaged in the stop grooves on the two fixed supports, thereby forming two position locking points in the front and back direction, preventing the handrail from deflecting left and right when under force, and increasing the structural stability of the handrail.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] This utility model has multiple embodiments, and the specific implementation methods are as follows: Example 1: As Figure 1-7As shown, this embodiment provides a cross-legged chair with adjustable armrests, including a seat 1 and armrests 2 on the left and right sides of the seat 1. The seat 1 and armrests 2 are respectively provided with fixed seats 4 and rotating seats 5. The rotating seats 5 and fixed seats 4 are rotatably connected by a through-hole pivot 41, allowing the armrests 2 to rotate in the left and right directions. In the upright state, the upper end of the armrests 2 is higher than the upper end of the seat 1 to support the arms. When the armrests 2 are rotated outward from the upright state to the tilted state, the seating space between the two armrests 2 and the seat 1 increases, making it easier for the person to sit cross-legged. The seat 1 includes a seat support for sitting and fixed rods on the left and right sides of the seat support. The fixed rods extend outward in the left and right directions, and the fixed seats 4 are installed on the outer ends of the fixed rods. The fixed seats 4 are provided with multiple circumferentially spaced stop grooves 42, and the rotating seats 5 are slidably connected to the stop grooves 42. The snap-fit ​​component 6, together with multiple stop slots 42, constitutes a stop adjustment structure. A control assembly is provided on the handrail 2, including an elastic element 61 and a linkage lever 72 rotatably connected to the handrail 2. The elastic element 61 acts to force the snap-fit ​​component 6 to always have a tendency to snap into the stop slot 42. The linkage lever 72 and the snap-fit ​​component 6 are connected by a flexible pull wire 62. The flexible pull wire 62 is typically a soft nylon rope or steel wire rope, which, while facilitating control of the snap-fit ​​component 6, offers lower cost and installation difficulty, lighter weight, and smaller space occupation. One end of the linkage lever 72 connected to the flexible pull wire 62 has a roughly T-shaped notch, forming a winding portion 721 at the end of the linkage lever 72. The flexible pull wire 62 is wound and fixed to the winding portion 721 through the T-shaped notch. The other end of the flexible pull wire 62 is also fixed to the snap-fit ​​component 6 by winding. like Figure 5-6 As shown, under the action of external force, the linkage lever 72 swings and pulls the flexible pull line 62, which will further tighten, causing the linkage latch 6 to disengage from the stop groove 42 and causing the elastic element 61 to deform. At this time, the armrest 2 is unlocked and can be flipped in the left and right directions. When the external force is removed, the elastic element 61 returns to its original position and forces the latch 6 to engage with the corresponding stop groove 42, thereby locking the armrest 2 in the predetermined position. This allows the operator to rotate the armrest 2 inward or outward and adjust it to the predetermined position according to their own needs, improving the convenience and user experience of the cross-legged chair.

[0024] Furthermore, to improve the structural stability of the handrail 2 and prevent it from tilting and deflecting when subjected to a leaning force, the fixed seat 4 includes two fixed supports arranged symmetrically front and rear, each fixed support having a stop groove 42 spaced apart along its circumference; the rotating seat 5 includes rotating supports corresponding to the fixed supports, each rotating support having a strip groove 51, and the locking member 6 is a locking pin that slides synchronously within the two strip grooves 51; compared to a single stop locking point, when the locking pin engages with the stop groove 42 under the action of the elastic member 61, two stop locking points are formed between the fixed seat 4 and the rotating seat 5 in the front and rear direction, which enhances the torsional strength of the handrail 2 and ensures the support stability of the handrail 2 after the locking member 6 engages with the stop groove 42.

[0025] Furthermore, in this embodiment, the elastic element 61 is a tension spring. The main function of the tension spring is to continuously apply an elastic force to the snap-fit ​​element 4, forcing it to snap into the stop groove 42. One end of the tension spring is hooked on the snap pin, and the other end can be hooked on the fixed base 4 or the rotating shaft 41. In this embodiment, only the tension spring is shown hooked between the snap pin and the rotating shaft 41. Both the snap pin and the rotating shaft 41 are provided with hooking grooves, and the hooks at both ends of the tension spring are hooked into the corresponding hooking grooves, so that the tension spring can stably apply an elastic force to the snap-fit ​​element 4.

[0026] Furthermore, to facilitate operator control of the linkage lever 72, the linkage lever 72 is connected to a control lever 7 that is easy to operate by hand. One end of the control lever 7 extends beyond the armrest 2, thereby providing an operating position for the operator. The control lever 7 is rotatably connected to the linkage lever 72, and the control lever 7 is slidably connected to the armrest 2, so that the control lever 7 can slide in a predetermined direction and drive the linkage lever 72 to rotate. Specifically, in this embodiment, the control lever 7 extends in the front-to-back direction, and a guide groove that runs through the armrest 2 is provided. The control lever 7 is slidably connected in the guide groove. The rear end of the control lever 7 is rotatably connected to the linkage lever 72, and the front end of the control lever 7 protrudes from the front end of the armrest 2, forming an operating part 71 that is easy to press by hand. In this embodiment, the operating part 71 is a button. The operator only needs to press the operating part 71 to control the locking member 6 to separate from the stop groove 42.

[0027] Furthermore, to facilitate the reset of the control lever 7 and the linkage lever 72, a mechanical spring 73 is provided on the handrail 2 to act on the control lever 7 or the linkage lever 72. When the handrail 2 is unlocked, the linkage lever 72 swings and causes the mechanical spring 73 to deform and store elastic force. When the handrail 2 is locked, the mechanical spring 73 releases the elastic force and causes the linkage lever 72 and the control lever 7 to reset. Specifically, the mechanical spring 73 in this embodiment is a compression spring. The compression spring is located between the handrail 2 and the control lever 7; or, the compression spring is located between the handrail 2 and the linkage lever 72. This embodiment only illustrates the structure where the compression spring is located between the handrail 2 and the control lever 7. To avoid large-scale bending caused by the deformation of the compression spring, a locking post is also provided on the handrail 2 and the control lever 7. The corresponding locking post is inserted into the end of the compression spring so that the compression spring can deform stably.

[0028] Furthermore, the mechanical spring 73 can also be a tension spring set between the handrail 2 and the control rod 7 or between the handrail 2 and the linkage swing rod 72. For example, a hanging lug can be set on the control rod 7 and the handrail 2 respectively, and the two ends of the tension spring can be hung on the corresponding hanging lugs, which can also reset the control rod 7 and the linkage swing rod 72, thereby achieving the same technical effect.

[0029] Furthermore, the control lever 7 has a protruding abutment part 74 on its body, and the handrail 2 has a corresponding limiting part 75. The limiting part 75 is located in front of the abutment part 74. When the control lever 7 is reset, the abutment part 74 contacts the limiting part 75 to restrict the control linkage 71 from disengaging from the handrail 2 in the front-back direction.

[0030] Furthermore, in this embodiment, one end of the flexible pull wire 62 is fixed to the linkage swing rod 72, and the other end is fixed to the snap-fit ​​member 6. The snap-fit ​​member 6 is slidably connected to the rotating seat 5 in a transverse direction. When the linkage swing rod 72 swings, it will generate an upward traction force on the flexible pull wire 62, resulting in the force direction of the flexible pull wire 62 being inconsistent with the direction of movement of the snap-fit ​​member 6. In order to ensure that the flexible pull wire 62 can stably pull the snap-fit ​​member 6, a guide wheel 63 is rotatably connected to the handrail 2. The outer wall of the guide wheel 63 is provided with an annular guide groove. The flexible pull wire 62 is wound in the guide groove and forms a roughly U-shaped structure. The longitudinal traction force generated by the linkage swing rod 72 on the flexible pull wire 62 is converted into a transverse pulling force on the snap-fit ​​member 6 through the guidance of the guide wheel 63, so as to guide the flexible pull wire 62 to pull the snap-fit ​​member 6 in a predetermined direction. Furthermore, in order to ensure that the linkage lever 72 exerts sufficient traction on the flexible cable 62, the linkage lever 72 in this embodiment is L-shaped. The linkage lever 72 includes a vertical lever and a horizontal lever. The horizontal lever is connected to the flexible cable 62, and the corresponding winding part 721 is also located at the corresponding end of the horizontal lever. The rotational connection position between the linkage lever 72 and the handrail 2 is located at the junction of the horizontal lever and the vertical lever. When the linkage lever 72 rotates, the vertical lever deflects backward, and the horizontal lever tilts upward and pulls the flexible cable 62 as taut as possible.

[0031] Furthermore, such as Figure 7 As shown, the handrail 2 in this embodiment is a hollow shell structure; the front end of the shell structure has a clearance hole 23 to avoid the exposed operating part 71; the shell structure includes a first shell 21 and a second shell 22 that are joined together, both of which are hollow structures; the handrail 2 with the shell structure is lighter and provides more space for the installation of various components in the control assembly; for example, in this embodiment, the linkage lever 72 is basically completely built into the shell structure, and the control lever 7 is also basically inside the shell structure, with only the operating part 71 exposed, making the handrail 2 look simpler and more beautiful.

[0032] Furthermore, to avoid the fixed seat 4 and the rotating seat 5 affecting the appearance of the cross-legged chair, the armrest 2 is provided with a receiving groove 24 with an open lower end. In order to avoid the fixed seat 4 and the rotating seat 5 as much as possible, the outer end of the receiving groove 24 is also open to the outside. The rotating seat 5 and the fixed seat 4 are located in the receiving groove 24 and do not protrude from the outer surface of the armrest 2; thus reducing the abruptness of the fixed seat 4 and the rotating seat 5 at the armrest 2.

[0033] Furthermore, such as Figure 3 As shown, to prevent the fixed seat 4 and the rotating seat 5 from being exposed, a cover 3 is provided inside the receiving groove 4. The cover 3 encloses the fixed seat 4 and the rotating seat 5 inside, making the handrail 2 look more concise. At the same time, to prevent the cover 3 from interfering with the rotating support 5 and the flexible pull wire 62, a clearance groove 31 is provided on the cover 3 to avoid the rotating support 5 and the flexible pull wire 62.

[0034] Example 2: Figure 8 As shown, the difference between this embodiment and the above embodiments is that, in this embodiment, the elastic element 61 is a compression spring disposed between the rotating seat 5 and the snap-fit ​​element 6 or between the armrest 2 and the snap-fit ​​element 6; one end of the compression spring abuts against the rotating seat 5 or the armrest 2, and the other end abuts against the snap-fit ​​element 6; specifically, a groove can be provided on the armrest 2 or the rotating seat 5, and the compression spring can be installed in the groove. In order to prevent the compression spring from bending when it deforms, a boss can also be provided on the snap-fit ​​element 6 so that the boss is inserted into the corresponding end of the compression spring; the compression spring also forces the snap-fit ​​element 6 to always have the tendency to snap into the stop groove 42, achieving the same effect as in the above embodiments.

[0035] Example 3: As Figure 9 As shown, the difference between this embodiment and the above embodiment is that the linkage swing rod 72 in this embodiment is a simpler straight rod, which is rotatably connected to the handrail 2; one end of the control rod 7 is rotatably connected to the linkage swing rod 72, and the other end is connected to the flexible pull line 62. The straight rod occupies less space, and when the linkage swing rod 72 swings, it can also generate traction force on the flexible pull line 72 and make it taut, achieving the same effect as in the above embodiment.

[0036] Example 4: Figure 10 As shown, this embodiment differs from the previous embodiment in that the locking member 6 is controlled by moving the control lever 7. Specifically, the control lever 7 and the linkage swing rod 72 are fixedly connected. One end of the control lever 7 protrudes from the handrail 2 and forms an operating part 71 that is easy to move by hand. Correspondingly, the clearance hole 23 left on the shell-shaped handrail 2 also allows the operating part 71 to swing. Based on this, the operator only needs to move the operating part 71 to make the linkage swing rod 72 rotate, thereby controlling the locking member 6 to separate from the stop groove 42.

[0037] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
