The chair provided by the embodiment is characterized in that two sides of the chair body 400 are respectively connected with one armrest 200, the armrest 200 can rotate along a vertical plane relative to the chair body 400 within a range of 90 degrees between horizontal arrangement and vertical arrangement, and the armrest 200 can rotate around a vertical axis between the back or the side of the armrest seat 100 when being vertically arranged, so that the armrest 200 can be rotated to the side of the chair body 400 when needed and horizontally arranged to limit the seated occupant on the chair body 400, and the armrest 200 can be rotated to the vertical arrangement when not needed to limit the seated occupant, so that the seated occupant can conveniently leave the chair body 400, and meanwhile, the armrest 200 can be further rotated around the vertical axis to the back of the armrest seat 100 when the lateral space of the chair body 400 needs to be saved, so that the seated occupant can conveniently walk and use in a narrow space.
When the chair is used, when a user needs to rotate the armrest 200, the user presses the locking button 210 to control the angle adjustment locking device to unlock the armrest 200, so that the armrest 200 can rotate along a vertical plane, when the user presses the locking button 210, the locking button 210 compresses the return spring 240 and is slidably inserted into the button seat 220 to extend into the armrest 200 to push the linkage plate 230 to rotate, when the linkage plate 230 rotates, the pull rod 250 is driven to pull the pawl 270 to rotate around the pawl shaft 280 against the elastic force of the torsion spring 290, so that the ratchet 260 connected with the armrest rotating shaft 140 is separated from the pawl 270, at the moment, the user can push the armrest 200 and the rotating positioning block 150 connected with the armrest 200 to rotate around the armrest rotating shaft 140 along the vertical plane between horizontal arrangement and vertical arrangement, so that the user can sit down to the chair body 400 or leave the chair body 400 conveniently, when the position of the armrest 200 needs to be locked again, only the locking button 210 needs to be released, and the compressed return spring 240 pushes the locking button 210 to move reversely to reset, the locking button 210 drives the linkage plate 230 to rotate reversely when moving reversely, the linkage plate 230 drives the pull rod 250 to move reversely when rotating reversely to push the pawl 270 to reset, and meanwhile, the elasticity of the torsion spring 290 also drives the pawl 270 to reset to be meshed with the ratchet wheel 260 for connection and fixation, so that the handrail 200 and the handrail rotating shaft 140 are connected through the meshed ratchet wheel 260 and the pawl 270, and a user cannot rotate around the handrail rotating shaft 140 along a vertical plane.
When the user rotates the armrest 200 to be vertically arranged, the pair of oppositely arranged turnover planes 170 on the outer wall of the rotating positioning block 150 connected to the armrest 200 are aligned with the top and the bottom of the opening 120, respectively, at this time, the user can push the armrest 200, so that the armrest 200 drives the rotating positioning block 150 and the armrest rotating shaft 140 to rotate around the connecting shaft 130 and to be separated from the connecting groove 110 through the opening 120, so as to rotate the armrest 200 to the back of the armrest seat 100 and the seat body 400, thereby freeing a space on the side of the seat body 400 for the user to move through, when the user needs to reuse the armrest 200, only the user needs to rotate the armrest 200 in the reverse direction, so that the armrest 200 drives the rotating positioning block 150 and the armrest rotating shaft 140 to rotate in the reverse direction around the connecting shaft 130 and enter the connecting groove 110 through the opening 120, so that the armrest 200 can be rotated to the side of the armrest seat 100 and the seat body 400, and at this time, the user can press the locking button 210 to control the angle adjustment locking device to unlock the armrest 200, and pushes the armrest 200 to rotate to a preset position along a vertical plane to limit a user sitting on the seat body 400; when the armrest 200 is not rotated to the vertical position, since the pair of oppositely disposed turning planes 170 on the outer wall of the rotary positioning block 150 are not aligned with the top and bottom of the opening 120, and at this time, the pair of oppositely disposed circular arc surfaces 160 on the outer wall of the rotary positioning block 150 are in limit fit with the inner wall of the connecting slot 110, the user cannot push the rotary positioning block 150 and the armrest rotary shaft 140 to rotate around the connecting shaft 130 to exit from the connecting slot 110 through the opening 120, thereby limiting the user to further turn the armrest 200 to the back of the armrest seat 100 and the seat body 400 only when the armrest 200 is rotated to the vertical position.
In addition, the ratchet 260 is connected with a stopper 300, and a first limit plate 310 and a second limit plate 320 are arranged in the armrest 200; when the armrest 200 rotates to the vertical arrangement and the horizontal arrangement along the vertical plane, the first limiting plate 310 and the second limiting plate 320 respectively block the stop block 300, so that the first limiting plate 310 and the second limiting plate 320 arranged in the armrest 200 are matched with the stop block 300 connected with the ratchet wheel 260, the armrest 200 is guaranteed to rotate only between 90 degrees between the horizontal arrangement and the vertical arrangement, and the armrest 200 is convenient for a user to use and retract.
The embodiments described above are some, but not all embodiments of the present application. The detailed description of the embodiments of the present application is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
