Description
Technical field
The invention belongs to the seating product technical field, the structure of particularly a kind of star base office chair system.
Background technology
Existing star base office chair major part cannot be lain only to sit.The star base office chair that some can be lain is to utilize the layback of adjustable backrest to realize.But its shortcoming is: one, the seat system that " to sit, cannot lie only " is unfavorable for people's rest at noon.Two, the seat system center of gravity of " utilizing the layback of adjustable backrest to realize " is fixed, and is non-adjustable, so the layback angle of backrest is limited, perhaps needs bigger chassis to strengthen the center of gravity sphere of action.(200910107067.4) can overcome the above problems " a kind of seat system that can lie of sitting " applied for before me, but its shortcoming is: can not utilize the air spring of existing star base office chair, to regulate the gentle power in a state of excitement of lifting.
Summary of the invention
The objective of the invention is to: provide a kind of and both can sit, can lie again, adjust center of gravity automatically, simultaneously the star base office chair of inclination of the seat backrest stationary adjustable.
For achieving the above object, technical solution of the present invention is: the star base office chair of dual purposes of sitting and lying, as shown in Figures 1 and 2, form by preceding four stars pin system, back slip pin system, seat support, backrest, alignment pin, hinge tube and castor.Four stars pin system is made up of star pin, air spring, supporting disk and tube connector as shown in Figure 3 before described, and wherein, described star pin, air spring, supporting disk are identical with existing star base office chair.Outline.A screwed hole is arranged on the star pin, be used to connect castor.Described tube connector is two horizontal tubes, welds together with supporting disk, and a plurality of screwed holes are arranged on it, is used to connect seat support.Described rear foot tube system as shown in Figure 4, by horizontal sleeve pipe, go up movable pulley, laterally sliding tube, downslide driving wheel, vertical sleeve pipe, vertical sliding tube and hinge are formed.Wherein, in the four stars pin system, other end opening top had last movable pulley to be used to reduce the frictional force that horizontal sliding tube slides before described horizontal sleeve pipe one end was welded on, and its effect is to be connected with preceding four stars pin system to reach to horizontal sliding tube slideway is provided.Described horizontal sliding tube has the downslide driving wheel with the end that horizontal sleeve pipe is connected, and is used to reduce the frictional force that horizontal sliding tube slides.A screwed hole is arranged at other end bottom, is used to connect castor.Laterally sleeve pipe, go up movable pulley, laterally sliding tube and lower slider wheel are formed a telescopic star pin.Described vertical sleeve pipe one end is welded on the horizontal sliding tube (or curved by a pipe), and other end opening is used to vertical sliding tube that slideway is provided.Described vertical sliding tube one end inserts vertical sleeve pipe, and the other end connects hinge.The another side of hinge connects backrest, thinks that backrest provides support a little.Vertical sleeve pipe and vertical sliding tube are formed an expansion link, to adapt to the lifting of seat support.Described seat support is common seat support, and top is seat surface, and the bottom is connected with two tube connectors of preceding four stars pin system.Described backrest is common backrest, and the back links to each other with hinge and hinge tube.Described alignment pin is made up of base, expansion link and lever as shown in Figure 5, and a hinge hole is arranged on the described base, is used for lever hinged.Also have screw hole to be connected on the base with horizontal sleeve pipe.One end of described expansion link has a hinge hole, be used for lever hinged, the other end can pass the through hole of base and horizontal sleeve pipe under the effect of lever, be stuck in the locating hole on the horizontal sliding tube, thus the collapsing length of fixed lateral sleeve pipe and horizontal sliding tube.Described hinge tube is made up of sleeve pipe, interior pipe, spring and hinge as shown in Figure 6, and its effect is fixing inclination of the seat backrest.Wherein, sleeve pipe is a cavity body, and pipe also is slidingly connected with it in the middle parcel, and end sealing connects spring.Sleeve outer wall has the connection ear, is used to connect backrest.Interior pipe is a cavity body, end sealing, middle parcel, connection spring.The another side of interior duct occlusion end is porose, is connected with hinge.One end of hinge is connected with interior pipe, and the other end is connected with the tube connector of preceding four stars pin system.Described castor is existing common universal wheel, by being threaded on five star pin.
Before four stars pin system, back slip pin system, seat support, backrest, alignment pin, hinge tube and castor combination as shown in Figures 1 and 2, described before the tube connector of four stars pin system connect seat support.In the four stars pin system, laterally the sliding tube bottom connected castor before the horizontal Socket welding of rear foot tube system was connected on, and welded with vertical sleeve pipe one end.Vertical sliding tube one end connects hinge, and the another side of hinge connects backrest.Described alignment pin is connected with horizontal sleeve pipe, and hinge tube connects backrest by the connection ear of sleeve pipe, interior pipe connection hinge, and hinge is connected with the tube connector of preceding four stars pin system.
Shown in Figure 7 is the state diagram of star base office chair when being in " lying ".
When this star base office chair used, identical with common star base office chair at ordinary times, during rest, by hand control alignment pin lever, and the back can make back slip pin system move backward to the acting in conjunction of layback at noon.Simultaneously, the inclination angle of backrest also can change gradually.Thereby realize that the people lies in the purpose of having a rest on the office chair.
After adopting above scheme, the invention has the beneficial effects as follows: the star base office chair both can be sat, and can lie again, adjusted center of gravity automatically, simultaneously the inclination of the seat backrest stationary adjustable.
