Description
Technical field
The present invention relates to the lazy-tongs of the coupled movements of a kind of seat support that is used for office chair and the chair back, it comprises basic support member, seat support support member and the back support part that is placed on the chair pillar.
Background technology
What term " lazy-tongs " was described is the assembly that providing in the office chair seat support basic structure makes the seat support and the chair back produce the interconnected motion of certain relative motion.Usually the seat support of installing cushion is installed on the seat support support member of office chair.Usefully the back support part that extends back from actual synchronization mechanism with the back support of office chair on upright cantilever.Seat support support member and the common flexible connection of back support part, thus for example the chair user leans on receding of the caused chair back of the chair back and makes the rear part edge of seat support descend.
In order to change " grade resistance " of the chair back, this lazy-tongs generally include the spring assembly that is used for lazy-tongs prestress.The prestressing force level depends on chair user's weight especially.
Summary of the invention
The purpose of this invention is to provide a kind of lazy-tongs, it does not need regulating spring tension force to change " grade resistance " of the chair back.
Above-mentioned purpose is realized by the lazy-tongs according to claim 1.It relates to a kind of system, wherein, can pivotally be directly connected to basic support member on the one hand around the back support part that axis of pitch pivots, on the other hand so that the mode of the Background Region lifting that causes the seat support support member of receding of the chair back is connected to the rear end part of seat support support member.Simultaneously, the seat support support member is connected to basic support member, makes the front area lifting of seat support support member.
Basic idea of the present invention is, the user of office chair makes he oneself " lifting " by leaning on the chair back.Unlike the prior art that relates to complicated controlling organization (worm gear, cogwheel, threaded rod etc.), need spring tension to regulate control.This has significantly reduced the manufacturing cost of lazy-tongs.Simultaneously, increased reliability.
Because seat support support member not only its Background Region is lifted, and its front area also is lifted simultaneously, therefore, seat support in the mode that has a predetermined relationship with the chair back synchronously simultaneously upwards and motion backward.Because therefore selected design is compared with solution commonly known in the art, the open angle of the chair back can be quite wide.Therefore, extreme back is put also and can be reached.
Advantageous embodiment of the present invention provides in the dependent claims.
Particularly advantageous design is that basic support member is connected to the front end of seat support support member via the linear guide parts.This helps the synchronous linear movement of the seat support and the chair back.Except having the linear guide parts of straight line guide tracks, different guide tracks obviously also are fine.The design of guide member, the position of guide member (for example, guide member gradient with respect to the horizontal plane) etc. help the individual and adjust being synchronized with the movement of seat support support member.For example, the seat support support member can with the chair back with the same moved further of the mode of absolute linearity, and any " inclination " can not appear.The appropriate designs of guide member also can make and produce " inclination " a little.Also can be by making tie point between basic support member and the seat support support member and other modification of the greater or lesser realization of distance of seat support leading edge.
When office chair have be designed to make the user follow the chair back to any banking motion of back position take the zone time, also can prevent to produce so-called " effect of shirt gauffer " very effectively.
The required lever geometry of " self-adjusting " of the present invention mechanism is preferably realized by following configuration: when from vertically the seeing of chair, and the back of the hinge axes that the rotation that links to each other between back support part and the basic support member links to each other between back support part and seat support support member.
Although, according to the present invention, do not need spring tension to regulate, can be provided for regulating the device of working region.This realizes in an advantageous manner that by the spring element that preferably is arranged on approximate horizontal position in the seat support support member this spring element is connected to the seat support support member on the one hand, is connected on the other hand across locating and being connected on the bolster of basic support member.Bolster has eccentric design, thereby by rotating it, the user will make the center of axle be shifted, and then make spring hang change, therefore help regulating between at least two kinds of spring tension settings (" firmly "/" soft ").
Compare with solution commonly known in the art, the invention provides very simple rotating mechanism on a kind of structure.This has reduced manufacturing cost.And except that its simple structure, it also significantly reduces so-called " effect of shirt gauffer ".In other words, under the situation that needn't seek help from complicated and expensive solution, realized very high ride quality.
Description of drawings
Below, describe an example of the present invention in detail referring to accompanying drawing.Accompanying drawing comprises:
Fig. 1 shows the perspective view of the lazy-tongs when diagonally opposing corner is seen from behind;
Fig. 2 shows the side view in the cross section of lazy-tongs;
Fig. 3 shows rearward the perspective view of the lazy-tongs when the top is seen; And
Fig. 4 shows the top view in the cross section of lazy-tongs.
The specific embodiment
Referring to Fig. 1, the feature of lazy-tongs is basic support members 1, and it is assembled to the top of chair pillar (not shown) by conical depression 2.Lazy-tongs comprise the forked back support part 4 in frame-like seat support support member 3 (referring to Fig. 3) and the top view substantially, and the frame 5,6 of back support part 4 is arranged on the both sides of basic support member 1.All figure all show the home position that back support part 4 has the approximate vertical position.
The chair back that is not shown specifically is assembled to back support part 4, and the chair back highly can be regulated in the modern handle official bussiness chair.The chair back also can fuse with back support part 4.
Can from diagram, find out that with regard to the actual dynamic structure of being concerned about, whole lazy-tongs are designed to respect to central longitudinal plane M (referring to Fig. 4) minute surface symmetry.Therefore, below description always relates to the many to structural detail of rotating mechanism.
On the one hand, back support part 4 is attached to the swivel bearing 8 on the basic support member 1, thereby back support part 4 directly is hinged to basic support member 1 via described swivel bearing 8.Like this, have the actual chair back back support part 4 can around the rotation 9 that passes swivel bearing 8 along inclined direction S tilt, as shown in Figure 2.Swivel bearing 8 is formed on the front of the leading edge 10 of frame 5,6.
On the other hand, back support part 4 utilizes the leading edge 10 of its frame 5,6 to be connected to the rear end part 12 of seat support support member 3 via hinge 11.Therefore, as the sweptback result of the chair back, seat support support member 3 is driven on incline direction S, and also owing to the lever construction that is formed by frame 5,6 is lifted.In other words, appearance is around the swing of the axis 13 of hinge 11.
When vertical 14 of chair is seen, the rotation 9 that back support part 4 links to each other with basic support member 1 is provided in the back of the hinge axes 13 that back support part 4 links to each other with seat support support member 3.And the hinge axes 13 that back support part 4 links to each other with seat support support member 3 is positioned at the top of the position of the rotation 9 that back support part 4 links to each other with basic support member 1.
As shown in Figure 2, because this design, when pressure is applied on the chair back and back support part 4 during along the downward hypsokinesis of incline direction S, the Background Region that is not only seat support support member 3 stands lifting H1.In addition, the front area of seat support support member 3 lifts (lifting H2) with the method for synchronization.In other words, lift simultaneously the front and back of taking the zone.Seat support 7 is lifted by integral body.
Referring to Fig. 2, take the cushion 20 on surface and make especially by the shaping foam.Cushion 20 can be divided into two different zones 21,22 of taking, they seat support vertical 14 on one be positioned at another after ground setting and installing difference aspect the cushion additional.Employed in this example taking under the surperficial form, the cushion thickness assembling of zone 21 with " standard " taken in the front portion of 30%-40% that is about the total length of cushion 20, and the rear portion take zone (70%-60% of total length) be equipped with can make the user pass through the back by and the variable cushion that sink to back.In the example shown, the cushion thickness in zone 22 is taken than the anterior thick 20mm at least of cushion thickness that takes zone 21 in the rear portion.Take the transient mode of taking zone 22 to the rear portion in zone 21 from the front portion preferably very soft and smooth, and without any protuberance.Making transitional region is that the form of the horizontal S that elongates can obtain good especially result.
Take zone 21 takes zone 22 transition to the rear portion and is arranged to make the user's who is in normal (" on average ") seating position weight mainly to be applied to the front portion to take on regional 21 from the front portion.When pressure is applied on the chair back, user's pelvis climb over horizontal S enter into the rear portion take the zone 22.Therefore, the user follows the chair back and moves downward backwards.In other words, user's the related pressure that moves backward and act on the Background Region of seat support 7 makes seat support " submit to ", and the form that makes the user lean on later on slips in the cushion 20.A series of high level of synchronization between the chair back and the user move through aforesaid way and realize.Thereby so-called " shirt gauffer " effect can be significantly reduced.
Foam is taken surperficial end 23 preferably freely towards the rear portion, thereby it can expand backward.In order to realize this point, preferably make cushion 20 adopt the open design of rear portion without any the gauge element.
Term " cushion " is interpreted as the flexible design of any kind of taking the surface, and no matter the material that uses.Except the shaping foam, can adopt other any elastomeric material, for example spring bag (spring packet) or such as the combined material of foam and silicon pad combination.For example use the dual area foam also to be fine.
The intensity of " grade resistance " of the chair back can be switched between " firmly " and " soft " two ranks in the example shown.For this reason, provide the extension spring 24 that is assemblied in approximate horizontal position in the seat support support member 3, its front end 25 is attached to eccentric support axle 19, and its rear end 26 is attached to seat support support member 3.Bolster 19 can turn to the second place around its axis from primary importance by the operating element 27 that is assemblied in side (referring to Fig. 4).As shown in Figure 4, because the design of the off-centre of bolster 19, therefore, when bolster 19 rotated, the front portion of extension spring 24 added holding position and also can change.The primary stress of extension spring 24 correspondingly changes.Thereby, can realize the intensity either large or small grade resistance relevant with the position of bolster 19.The quantity of extension spring 24 is not limited to one.According to design, the assembling that can walk abreast of other extension spring 24.
In order to limit the inclination of the chair back, be provided with apparently not in this detailed description but the mechanism that handles by lever 28.
