Description

Technical Field

[0001] The utility model relates to the technical field of office furniture, in particular to a chair seat with integrated multiple operation adjustment structures. Background Art

[0002] In order to make lunch breaks more comfortable, more and more people now prefer to use swivel chairs with footrests. Such swivel chairs can be used as ordinary office chairs. When you need to lie down to rest, you can deform the chair, bring out the footrest to support your feet, and lay down the backrest to support your back, so that you can rest in a nearly flat position. However, such deformable chairs in the prior art have some shortcomings: first, they are too large in size. In order to achieve the purpose of deformation, some deformable chairs have too many deformation structures, resulting in a larger size of the entire deformable chair, and some deformable chairs cannot completely retract the footrest, affecting the user experience as an ordinary office chair; second, the transmission structure of the deformation mechanism used in the traditional deformable chair has defects, which is prone to imbalance, shaking and other phenomena, affecting the safety and reliability of use.

[0003] It can be seen that there is still room for improvement in the current transformable chair, which should be optimized to simplify its structure, reduce the overall size, and improve the stability and reliability of the structure, and improve the balance during use. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the prior art. Utility Model Content

[0008] Furthermore, the control unit is used to operate and control the lifting and lowering of the seat, the pitching of the backrest, the extension and retraction of the footrest, the on and off of the power supply, etc. Its component structure can be constructed in various forms and is not limited to a single form.

When such a solution is adopted, the lifting control handle is connected to a cable and the state of the lifting hydraulic rod is adjusted by controlling the cable, so that the lifting of the chassis shell can be adjusted.

[0010] Furthermore, the chassis frame is the core structure for shape adjustment. Through its deformation, it can adjust the pitch of the seat back, the pitch of the seat bag, and the extension and retraction of the footrest. Through the adjustment of the chassis frame, it can better fit the human body structure and achieve a higher degree of comfort. The structure of the chassis frame can be constructed in various forms, which is not limited to the only one. Here, it is optimized and one of the feasible options is proposed: the chassis frame includes a bottom support frame and a movable support frame arranged on the bottom support frame, and the movable support frame is driven by a driving mechanism and moves relative to the bottom support frame. The movable support frame is provided with an articulated seat, and the driving mechanism includes a telescopic driving rod articulated with the articulated seat, and the front end of the telescopic driving rod is connected to the articulated seat through a detachable locking pin structure; the front end of the movable support frame drives the footrest mounting seat to extend or retract through a telescopic connecting rod structure, and the rear end of the movable support frame is hingedly provided with a tailstock assembly, and a synchronous connecting rod is provided between the telescopic connecting rod and the tailstock assembly, and the synchronous connecting rod makes the footrest mounting seat and the tailstock assembly extend or retract synchronously.

[0011] The chassis frame disclosed above is connected to the base of the swivel chair through the bottom support frame, and the movable support frame is offset forward and backward relative to the bottom support frame and rises and falls synchronously. The movable support frame corresponds to the seat bag of the seat, thereby realizing the adjustment of the seat cushion; and the extension and retraction process of the footrest mounting seat realizes the extension use and storage of the footrest structure. At the same time, the tailstock assembly is connected to the backrest to adjust the inclination angle of the backrest, and is adjusted synchronously with the footrest structure to realize the deformation operation.

[0012] Furthermore, in the present invention, the footrest structure is controlled to be unfolded or retracted by a telescopic connecting rod structure, and the telescopic connecting rod structure can be constructed in various forms, which are not limited to a single one. Here, an optimization is made and one feasible option is proposed: the telescopic connecting rod structure includes two groups of connecting rod assemblies, and the two groups of connecting rod assemblies are symmetrically arranged on both sides of the front end of the movable support frame. When such a solution is adopted, the two groups of connecting rod assemblies are adjusted and deformed synchronously, which can improve the stability of the footrest structure in outward extension and retraction, and can also better maintain balance during use.

[0014] Furthermore, the power rod is used to apply a driving force to the first transmission rod, so that the entire telescopic link structure undergoes linkage deformation and extends or retracts. The matching structure of the power rod and the first transmission rod is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the first end of the power rod is hingedly matched with the first transmission rod, and the second end of the power rod is pulled and moved by the driving force and drives the first transmission rod to move. When such a solution is adopted, the power rod applies a pulling force or a pushing force to the first transmission rod, so that the first transmission rod rotates along the hinge with the movable support frame, thereby driving the first linkage rod, the second transmission rod, the second linkage rod and the pedal mounting seat to synchronously displace.

[0015] Furthermore, the bottom support frame is used to connect to the bottom bracket of the swivel chair as a fixed support structure, and the movable support frame arranged thereon is displaced relative to the bottom support frame, which is specifically achieved through the connecting parts between the two. The setting method of the connecting parts can adopt a variety of schemes, which are not limited to the only one. Optimization is carried out here and some feasible options are proposed: a plurality of connecting parts are hingedly arranged between the bottom support frame and the movable support frame, and the connecting parts are used to prop up the movable support frame upward and synchronously offset it forward and backward.

[0017] Furthermore, the tailstock assembly is connected and cooperated with the backrest of the swivel chair, driving the backrest and the footrest mounting seat to move synchronously and facilitate the user to stretch the waist, back and legs. The structure of the tailstock assembly is not limited to a single one. It is optimized here and one of the feasible options is proposed: the tailstock assembly includes a plurality of tailstock connectors hinged to the movable support frame, and adjacent tailstock connectors are connected and deflected synchronously through synchronous tailstocks. When such a solution is adopted, multiple tailstock connectors are set to jointly connect the backrest, which can improve the connection stability of the backrest and make the adjustment of the backrest more balanced and reliable.

[0018] Furthermore, in the present invention, the synchronous connecting rod is used to realize the synchronous displacement deformation of the footrest mounting seat and the tailstock assembly.

After releasing the control button, the driving mechanism stops and maintains the current state; after pressing the operation button again, the driving mechanism moves in the opposite direction and drives the movable support frame to reset, and the reset degree is controlled by controlling the pressing duration.

[0020] Furthermore, the structure of the movable support frame is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the movable support frame includes two top and side plate frames arranged opposite to each other, the two top and side plate frames are connected and fixed by a transverse top frame, and the movable driving end of the driving mechanism is connected and matched with the transverse top frame.

When the telescopic drive rod needs to be removed from the hinge seat, it is only necessary to remove the locking pin and the pin rod in sequence.

[0048] The chassis frame disclosed in the present embodiment is connected to the base of the swivel chair through the bottom support frame 1, and can be rotated and raised and lowered by a pneumatic control component; the movable support frame 2 is offset forward and backward relative to the bottom support frame 1 and is raised and lowered synchronously, and the movable support frame 2 corresponds to the seat bag of the seat, thereby realizing the adjustment of the seat cushion; and the extension and retraction process of the footrest mounting seat 5 realizes the extension use and storage of the footrest structure, while the tail stock assembly is connected to the backrest to adjust the inclination angle of the backrest, and is adjusted synchronously with the footrest structure to realize the deformation operation.
