Description
Technical field
The present invention relates to a kind of lazy-tongs, be used for the seat support-back movement that is associated of office chair, have basic bearing part, a seat support bearing part and a backrest bearing part that can be placed on the chair post.
Background technology
Title " lazy-tongs " is understood to be in the construction package in the seat support substructure of office chair, and they follow the kinematics of bringing to cause that seat support leans on and backrest relative motion that intercouple, that determine relative to each other.Be equipped with the seat support of the seat support face that is provided with cushioning in all cases of office chair at described seat support bearing part.The backrest bearing part that is extended back by actual lazy-tongs in common mode is at the backrest of the described office chair of support carrying of trend upwards.Seat support bearing part and backrest bearing part be radial type coupling as follows usually, that is, described backrest backward, as its can be for example the downward descending motion of the trailing edge by seat support as described in chair user having induced against caused oscillating motion to the backrest.
Advantageously, the swing resistance of backrest can be adjusted relatively with user's weight for the comfortable use of chair.In order to change the swing resistance of backrest, this homochronousness mechanism has the elastic system that at least one more or less expends, and is used for pre-tensioner described lazy-tongs.
Summary of the invention
Task of the present invention provides a kind of lazy-tongs, and it makes up especially simply and therefore make inexpensively on can structure, and however the comfort of common lazy-tongs is provided.In particular, described lazy-tongs should not need or only need flexible member seldom or weak.
This task solves by the lazy-tongs according to claim 1.Favourable design of the present invention is put down in writing in the dependent claims.
According to setting of the present invention: described seat support bearing part directly, just directly do not use coupling element, as joint piece or analog ground with as described in basic bearing part radial type be connected, wherein, the backrest bearing part that is connected with described basic bearing part simultaneously directly, namely can swing at described basic bearing part around an axis of pitch and described seat support bearing part radial type as follows are connected, that is, the oscillating motion backward of described backrest induce described seat support bearing part forefoot area lift motion.
Basic thought of the present invention is: the user of office chair comes oneself upwards to lift by the described backrest of load.In other words, the user described lazy-tongs overcome in by the manipulation that pushes back backrest itself, be placed on the weight acting on the seat support.Desirable swing resistance is almost adjusted based on user's weight thus voluntarily.Need be not known by prior art, be used for adjusting the elastic system of swing resistance compression spring or the tension spring form of a plurality of parallel connections (for example with) and the adjustment mechanism (worm gearing, gear, threaded rod etc.) that expends.Come to reduce significantly the manufacturing cost of lazy-tongs thus.Improve reliability simultaneously.
The lever geometry that is used for " self-adjusting " of the present invention mechanism is realized in the following way: the axis of oscillation that is connected of described backrest bearing part and described basic bearing part is after the seat support longitudinal direction is arranged in the joints axes that is connected of described backrest bearing part and described seat support bearing part.
Number and then the manufacturing cost of member are especially little because not only backrest bearing part and described basic bearing part, and described seat support bearing part and described basic bearing part directly, just directly and do not have additional member in the middle of connect the ground radial type and be connected.
By the structural layout of structural detail, when the described backrest of swing, lift the forefoot area of described seat support bearing part.In the case, it is big that the spacing between the forefoot area of described seat support bearing part and the described basic bearing part becomes, and the rear region of described seat support bearing part firmly is connected with described basic bearing part reservation.Carry out axis of oscillation that seat support connects around described seat support bearing part-basic bearing part backward thus with the inclination with respect to a ratio that limits of the motion of described backrest.Have desired pull(ing) effect thus, wherein, described seat support bearing part changes with respect to the angle of described backrest bearing part.
User's weight is directly to the swing resistance generation effect by the perception of user's energy.Lighter user must the time overcome in swing and compares obviously less swing resistance with heavier user.In swing during described backrest, subjectively obtain identical " feeling " resistance for each user.This layout by swinging mounting spare and joint and the design of this layout can be adaptive to the chair proposed requirement uniquely with being synchronized with the movement of described seat support bearing part.Therefore can for example adjust by the change of the spacing between leg supporting member or the joint, how degree ground tilts described seat support bearing part when described backrest is swung.
Compare with the known solution of prior art, according to the present invention proposes better simply swing mechanism on a kind of structure, wherein, so-called " shirt is pulled out effect " obviously reduces.In other words realize extra high seat support comfortableness, and needn't use that expend and expensive solution.
With respect to other known " self-adjusting " structure, the characteristic of these lazy-tongs is, these lazy-tongs are flat especially structures, thereby make corresponding construction package only need considerably less installing space.Simultaneously, described mechanism makes up extremely simply.Desirable being synchronized with the movement can be that backrest bearing part, basic bearing part and seat support bearing part are realized with three known parts, and they are connected to each other by means of three pin joints only.
Description of drawings
Explain with reference to the accompanying drawings below the embodiments of the invention.In the case:
Fig. 1 shows the side view of the lazy-tongs in home position;
Fig. 2 shows the side view of the lazy-tongs in swing position backward.
The specific embodiment
Whole accompanying drawings only schematically shows described lazy-tongs and has the important part for the present invention.Identical Reference numeral is at this element corresponding to same or similar function.
Lazy-tongs have basic bearing part 1, and this basis bearing part is placed on the upper end of a chair post (not shown) by means of a circular cone acceptance division 2.In addition, described lazy-tongs comprise the backrest bearing part 4 of seat support bearing part 3 and a fork-shaped in front view of frame shape basically, and the curb girder 5 of described backrest bearing part is with respect to two side arrangement of basic bearing part 1.Seat support bearing part 3 is provided for receiving or assembling the seat support face (not shown) of preferred cushioning.Described assembling is carried out in common mode by the tightening member that is not shown specifically.Be mounted with the backrest that is not shown specifically at backrest bearing part 4, this backrest can carry out Height Adjustment under the situation of the office chair in modern times.Described backrest can be connected with backrest bearing part 4 also single type.
Whole lazy-tongs minute surface with regard to relating to actual kinematic middle fore-and-aft plane makes up symmetrically.Just in this point, in the following description always from the paired structural detail that occurs in the both sides of actual swing mechanism.
Figure 1 illustrates home position, in this home position, described seat support bearing part 3 is essentially horizontally arranged.Fig. 2 shows the lazy-tongs in the swing position backward of backrest bearing part 4.The forefoot area of seat support bearing part 3 is lifted at this.
The rear region 25 of seat support bearing part 3 directly is hinged on the described basic bearing part, exactly is hinged on the first swinging mounting spare 27 of basic bearing part 1 by supporting shaft 6.Seat support bearing part 3 thus can be around 13 swings of horizontal axis of oscillation.For the described swinging mounting spare 27 of structure in the zone of basic bearing part 1, the first assembling leg 12 of described seat support bearing part 3 is extended towards basic bearing part 1 downwards by the loading plate 11 of seat support bearing part 3.Because swinging mounting spare 27 is arranged on the rearward end 9 of described basic bearing part 1, so seat support bearing part 3 and/or seat support also can be swung uninterruptedly, the trailing edge that they surpass described basic bearing part 1 stretches out, and need not be for this reason the special and structural measure that expends.
Observe at seat support longitudinal direction 14 and be arranged in by after backrest bearing part 4 is hinged on the joints axes 22 that limits on the seat support bearing part 3 by backrest bearing part 4 being hinged on second axis of oscillation 15 that limits on the basic bearing part 1, thus make backrest on swaying direction 7 around axis of oscillation 15 oscillating motion backward of the second swinging mounting spare 28 induced seat support bearing part 3 around the rotation of the axis of oscillation 13 of the first swinging mounting spare 27 so that only seat support bearing part 3 forefoot area 26 lift motion 23.The Background Region 25 of seat support bearing part 3 is not lifted.The part (not shown) that is in axis of oscillation 13 back of seat support descends.
In other words, lift by the lever system of seat support bearing part 3 being taken and being formed based on the curb girder 5 by backrest bearing part 4 at swaying direction 7 to back lower place oscillating backrest.Backrest bearing part 4 pin joint 15 on aspect the basic bearing part 1 and on aspect the seat support bearing part 3,22 position define the lever element as integrated component part spare of forefoot area of the curb girder 5 of backrest bearing part 4 according to the present invention.
Between first axis of oscillation 13 and second axis of oscillation 15 and the spacing between second axis of oscillation 15 and the joints axes 22 define the synchronized relation of described mechanism, that is to say that backrest bearing part pendulum angle 29 is with respect to the transformational relation of seat support bearing part pendulum angle 30.Selected axis arranged has been determined the lever geometry of described mechanism, and has stipulated that seat support bearing part 3 in which kind of mode lifts and synchronously move with the backrest of swing.
In the embodiment illustrated in the accompanying drawings, first axis of oscillation 13 and joints axes 22 are on the height in the home position of not swing basically, and second axis of oscillation 15 is arranged than the highland only not obviously.Spacing 17 for example only is 2mm.Thus, obtain the installation form of very flat structure in addition.
Be that 107mm and the spacing from first axis of oscillation 13 to joints axes 22 32 are 137mm by first axis of oscillation 13 in a particularly advantageous embodiment to the spacing 31 of second axis of oscillation 15.In the position that the maximum of described lazy-tongs is swung backward, do not change the order of described axis 13,15,22 layout yet.
By setting up to second axis of oscillation 15 or to the bigger spacing 31,32 of joints axes 22 in simple especially mode on the structure on the rearward end 9 that first axis of oscillation 13 is arranged in basic bearing part 1, this causes particularly advantageous synchronized relation, wherein, the swing of backrest bearing part 4 non-constant width backward only causes very little the lifting of the preceding seamed edge 8 of seat support bearing part 3.One embodiment proves advantageous particularly, and wherein, when backrest bearing part 4 had roughly 25 ° swing 29 to the back lower place, seat support bearing part 3 was roughly 5.5 ° with respect to the inclination 30 of horizontal initial bit attitude.Under the state after the swing, be 11mm in the example that the vertical spacing 33 between second axis of oscillation 15 and the joints axes 22 draws in Fig. 2.
Realize the mechanical features curve of approximately linear in this case, under the situation of this mechanical features curve, the swing resistance is fixed at the approximate weighing apparatus of whole motion flow process.At this, seat support bearing part 3 only lifts in forefoot area 26, and thus, the motion of the people intuitively flow process in swinging is backward supported.
Guarantee that by described swing mechanism the backrest bearing part 4 that has backrest can be around an axis of oscillation, second axis of oscillation 15 described here in swaying direction 7 swings.Side by side, backrest oscillating motion backward induces the lifting of forefoot area 26 of seat support bearing part 3 to move 23.In the swing of the back lower place, do not carry out seat support bearing part 3 forward or backward moving on seat support longitudinal direction 14 at this at backrest.Seat support bearing part 3 only shows the oscillating motion around described first axis of oscillation 13, and basic bearing part 1 is fixed with two swinging mounting spare 27,28 retention positions.
In case in order to support to influence in other words the swing resistance and to stop backrest controllably not tumbled backward and for the no longer load of user of backrest, returning of position the insurance to home position in of backrest after by swing, service has the elastic system with one or more flexible members.For example relate to the elastic component of in the zone of preceding basic bearing part 18, arranging 21 at this, this elasticity one side is supported on the basic bearing part 1 and opposite side is supported on the curb girder 5 of backrest bearing part 4, and this elastic component when the described backrest bearing part 4 of swing by load.21 needs of flexible member are constructed more weakly, thereby always make only very little resilient force to the member of described mechanism, and this causes the stress of the obvious attenuating of described member in conventional relatively mechanism.
In the embodiment that in Fig. 1 and Fig. 2, draws:
A) described backrest bearing part 4 and described basic bearing part 1 are only by unique direct connection the with swinging mounting spare 28 forms;
B) described backrest bearing part 4 and described seat support bearing part 3 are only by unique direct connection the with joint 16 forms; And
C) described seat support bearing part 3 and described basic bearing part 1 are only by unique directly being connected, being another swinging mounting spare 13 and connecting by an indirect connection, wherein, described indirect connection is set up by backrest bearing part 4, and this backrest bearing part is connected by described joint 16 and is connected by described swinging mounting spare 15 with described basic bearing part 1 on the other hand with described seat support bearing part 3 on the one hand.
This embodiment is particularly advantageous, is synchronized with the movement because therefore can realize having the desired of few especially member.But alternatively also feasiblely be, substitute the joint 16 that is integrated in the described backrest bearing part 4, for described backrest bearing part 4 being connected on the described seat support bearing part 3 and use one or more coupling elements, they are hinged on the backrest bearing part 4 on the one hand and are hinged on the other hand on the seat support bearing part 3.Thus the number of axis is brought up to four, obtain other possibility for the configuration that is synchronized with the movement thus.Still keep the basic structure that obtains described mechanism simultaneously, have mode, the feature above-mentioned of the motion that relates in particular to described lever principle and seat support bearing part 3.
All can be individually and be important in the mode of any combination with one another to the present invention in the feature shown in specification, claim and the accompanying drawing.
