Description

Technical Field

[0001] The present invention relates to a control mechanism of a swivel chair, in particular to a control assembly of a rocking chair, belonging to the technical field of swivel chairs. Background Art

[0002] Chairs are a common piece of furniture. Office chairs are a type of chair, broadly referring to chairs used in office settings, such as those for conference tables and desks. Early office chairs were mostly wooden H-shaped chairs, but swivel chairs later became popular. With the evolution of conference tables and desks, as well as office decor styles, the shape and appearance of swivel chairs have also undergone significant changes. Currently, office chairs have become the most important type of swivel chair, and in many cases, they are even equated with office chairs.

[0003] To enhance the comfort of swivel chairs, a reclining function has been designed into them. These chairs are generally called reclining chairs. Retaining all the functions of a traditional swivel chair, a reclining chair adds a rocking feature with elastic damping. This is achieved through an improved tray. Specifically, the integrated tray is divided into a hinged bottom plate and an upper plate, forming a seesaw structure. Springs are added to generate an elastic restoring force when the seat reclines. Users can gently rock their bodies while sitting on it, enjoying a comfortable and relaxed feeling.

[0004] For example, the utility model patent with authorization announcement CN 201108192Y discloses a chair chassis with a conveniently tilted base, which actually discloses a tray for a rocking chair. It includes an upper plate and a rotating middle plate. The rotating middle plate is connected to the upper plate via a fixed axis A. A front spring and a rear spring are provided between the upper plate and the rotating middle plate. Under the action of the front spring and the rear spring, a balanced return is achieved. The rotating middle plate can rotate around the fixed axis A but is locked by the locking shaft. Pressing down on the return shaft triggers the return rotating iron plate to rotate around the rotating fixed axis. The end of the locking shaft extends out of the return fixed seat and retracts into the return fixed seat, making it unable to support the vertical edge of the rotating middle plate, thereby unlocking. When the downward pressure is released, the end of the locking shaft extends out of the return fixed seat under the action of the return spring, clamping the vertical edge of the rotating middle plate to achieve locking. When unlocked, it is in the rocking state.

[0005] However, in the above technical solution, the presence of the return shaft interferes with the seat's placement. Therefore, the chassis needs to be moved back, and in actual use, a tray is required, rather than directly securing the seat to the rotating center plate. Furthermore, the return shaft's placement does not align with user habits. Return spring A is fixedly connected to the return rotating iron plate at one end and the locking shaft at the other end, with return spring B mounted on the locking shaft. Return spring A not only performs a restoring function but also transmits tension, resulting in an unstable locking and unlocking mechanism, which occasionally causes jamming during use.

[0019] The present invention is further explained below with reference to the accompanying drawings.

[0020] This specific embodiment is only 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 description of the present invention will be protected by patent law as long as they are within the scope of the claims. Example

[0021] like Figures 1 and 2 As shown, a control assembly of a reclining chair includes a tray 1, a reclining control component 2, and a lifting control component 3. The reclining control component 2 and the lifting control component 3 are installed based on the tray 1.

[0022] like Figure 3 As shown, the tray 1 includes a bottom shell 11, an upper cover 12, a hinge shaft 13, a shaft sleeve 14 and a spring guide column 15. The bottom shell 11 is provided with a first shaft hole 111, and the upper cover 12 is provided with a second shaft hole 121. The first shaft hole 111 and the second shaft hole 121 are combined to form the shaft hole of the hinge shaft 13, and the shaft sleeve 14 is sleeved in the shaft hole. The hinge shaft 13 passes through the shaft sleeve 14 to hinge the upper cover 12 to the bottom shell 11, so that the upper cover 12 becomes a seesaw structure with a limited rotation angle. Figure 1 As shown, when the tray 1 is in use, the base of the seat of the swivel chair is installed thereon. Specifically, the base is fixed to the tray 1 by an upper cover plate 12.

[0023] like Figure 4 As shown, the bottom shell 11 is also provided with a gas spring mounting portion 112, a guide column mounting portion 113, a first pad 114 and a second pad 115. The first pad 114 and the second pad 115 are symmetrically distributed on both sides of the hinge shaft 13. Figure 3 and Figure 4 It can be seen that the spring guide pillars 15 are mounted on the guide pillar mounting portion 113 and are disposed between the bottom shell 11 and the upper cover 12. There are two pairs of spring guide pillars 15, which are also symmetrically distributed on both sides of the hinge shaft 13.

[0024] Combine Figure 1 and Figure 4 It can be seen that a portion of the bottom shell 11 is exposed from the bottom of the base, at least exposing the gas spring mounting portion 112 to facilitate the installation of the gas spring. The base can rotate relative to the bottom shell 11.

[0025] like Figure 3 and Figure 4 As shown, the reclining control assembly includes a controller 21 and a control terminal 22 for controlling the controller. The vacant area reserved between the first pad 114 and the upper cover 12 is the first control area, and the vacant area reserved between the second pad 115 and the upper cover 12 is the second control area. The controller 21 opens / releases the active state of the upper cover 12 by leaving / entering the first control area and the second control area at the same time. When the upper cover 12 is opened to the active state, the seat can shake gently and have an elastic damping feeling when shaking. Specifically, as Figure 6 As shown, the ends of the first card platform 211 and the second card platform 212 both extend out of the carrier 213. The parts of the controller 21 that leave / enter the first control area and the second control area are the first card platform 211 and the second card platform 212.

[0026] like Figures 5 and 6 As shown, the control terminal 22 includes a cable sheath 221 with a proximal end and a distal end and a manual control mechanism 222. The proximal end of the cable sheath 221 includes a cable proximal end 2211 and a sheath proximal end 2212, and the distal end of the cable sheath 221 includes a cable distal end 2213 and a sheath distal end 2214; the controller 21 includes a first card platform 211 and a second card platform 212 respectively cooperating with the first pad and the second pad, and a carrier 213 that carries the first card platform and the second card platform and allows them to be extended and retracted in the horizontal direction toward the first control area and the second control area respectively; the proximal end 2211 of the cable is used to be fixedly connected to the bottom shell of the seat, and the proximal end 2212 of the sheath is fixedly connected to the manual control mechanism 222; the distal end 2213 of the cable is fixedly connected to the second card platform 212 away from the manual control mechanism 222, and the distal end 2214 of the sheath is fixedly connected to the first card platform 211 close to the manual control mechanism 222; the controller 21 also includes a return spring 214 installed based on the carrier and arranged between the first card platform 211 and the second card platform 212 to provide elastic repulsive force. The carrier 213 is also provided with a first limiting portion 2131 and a second limiting portion 2132 for limiting the first card platform 211 and the second card platform 212 from moving away from each other; a third limiting portion 2133 and a fourth limiting portion 2134 for limiting the first card platform 211 and the second card platform 212 from moving closer to each other; and a mounting hole 2135 for fixing itself to the bottom shell 11.

[0027] The first clamping platform 211 close to the manual control mechanism 222 is provided with a mounting groove 2111 for facilitating the insertion of the distal end 2214 of the sheath and the insertion of the distal end 2213 of the cable.

[0028] like Figure 7 As shown, the control assembly also includes a lifting control component 3, which includes a second cable sheath 31 with a proximal end and a distal end, a second manual control mechanism 32, and a rotating control member 33 with a cable connecting end and a paddle end abutting the end of the gas spring support column; the proximal end of the second cable sheath 31 includes a second cable proximal end 311 and a second sheath proximal end 312, and the distal end of the second cable sheath 31 includes a second cable distal end 313 and a second sheath distal end 314; the second sheath distal end 314 abuts the bottom shell 11, the second cable distal end 313 is fixed to the cable connecting end, the second cable proximal end 311 is used to be fixedly connected to the seat bottom shell or the second manual control mechanism 32, and the second sheath proximal end 312 abuts the second manual control mechanism 32 or the seat bottom shell; the lifting control component 3 also includes a second return spring 34 arranged between the rotating control member 33 and the bottom shell 11.

[0029] When the hand-controlled mechanism is pulled, the cable on the first side pulls the second card platform at the far end, and the sheath on the second side pushes the first card platform at the proximal end, and at the same time, the first card platform and the second card platform move towards each other, so that they are simultaneously out of the first control area and the second vacant area, and the upper cover is opened to the active state, so that the user can sit on it and shake it gently, and have an elastic damping feeling when shaking; it is controlled by a wire control component, with a brake-like feel and a good user experience; and there is a reset spring inside the controller to facilitate the reset of the hand-controlled mechanism. Example

[0030] The control assembly of the reclining chair of this embodiment is different from the embodiment in that the control terminal for controlling the controller is a rod control component, the bottom shell 11 and the controller 21 have corresponding changes, and the function of the lifting control component 3 is also integrated into the rod control component.

[0031] Specifically, such as Figures 8-11As shown, a control rod base 116 and a control rod lower mounting port 117 are provided on the bottom shell 11; the controller 21 includes a control body having a first clamping platform 211 and a second clamping platform 212 respectively cooperating with the first pad 114 and the second pad 115, a carrier 213 that carries the control body and allows it to move away from the first control area or the second control area, a pushing body 215 arranged inside the control body and capable of moving relative to the control body, and two return springs 214 arranged between the two ends of the pushing body and the two clamping platforms of the control body. The rod control assembly includes a control rod 223 installed based on the control rod base 116 and having a paddle end abutting the end of the gas spring support column, a torsion plate 224 axially fixed to the control rod, a dial body 226 having a sleeve 2261 sleeved on the hinge shaft and a rotating paddle 2262 for triggering the pushing body, a connecting rod 225 connecting the torsion plate and the dial body, and a control rod fixing seat 227 for installing the control rod to the control rod base.

[0032] In addition, for the installation of the control rod, the cover plate 12 has an upper control rod installation opening 122, and the bottom shell 11 has a lower control rod installation opening 117. The arrangement of the upper control rod installation opening 122 and the lower control rod installation opening 117 facilitates the insertion of the control rod.

[0033] When controlling the lifting and lowering of the chair seat, the control lever is pulled upward to trigger the gas spring, making it retractable; when controlling the upper cover, the control lever is rotated so that the torsion plate pulls the dial body to rotate through the connecting rod, so that the rotating dial acts on the pushing body inside the carrier, so that the first card platform and the second card platform move in the same direction at the same time, thereby simultaneously escaping from the first control area and the second control area, opening the active state of the upper cover, so that the user can gently shake it when sitting on it, and have a sense of elastic damping when shaking; it is controlled by the rod control component, with a feel like physical unlocking, and a good user experience; and a reset spring is provided inside the controller to facilitate the reset of the control lever.
