Description
Technical field
The present invention relates to a kind of lazy-tongs, for the seat support-back movement be associated of office chair, the basic bearing part on chair post, a seat support bearing part and a backrest bearing part can be placed on one.
Background technology
Title " lazy-tongs " is understood to be in the construction package in the seat support substructure of office chair, their with kinematics of bringing cause seat support lean on backrest intercoupling relative to each other, the relative motion determined.Described seat support bearing part is equipped with the seat support being provided with the seat support face of cushioning in all cases of office chair.The backrest bearing part extended back by actual lazy-tongs in common mode carries the backrest of described office chair on a support upwards moved towards.Seat support bearing part and backrest bearing part be radial type coupling as follows usually, that is, described by dorsoposterior, as its can such as by chair user on backrest against caused oscillating motion induction of as described in the downward descending motion of the trailing edge of seat support.
In order to the comfortable use of chair, advantageously, the swing resistance of backrest can adjust relatively with the weight of user.In order to change the swing resistance of backrest, this kind of lazy-tongs have at least one elastic system more or less expended, for pre-tensioner described lazy-tongs.
Summary of the invention
Task of the present invention is to provide a kind of lazy-tongs, and it can build and therefore manufacture inexpensively simply especially in structure, and however provides the comfort of common lazy-tongs.In particular, described lazy-tongs should not need or only need little or weak flexible member.
This task is solved by lazy-tongs according to claim 1.Favourable design of the present invention is recorded in the dependent claims.
Arrange according to the present invention: described seat support bearing part directly, namely directly do not apply coupling element, as joint piece or analog with as described in basic bearing part radial type be connected, wherein, backrest bearing part that be simultaneously directly connected with described basic bearing part, that namely can swing on described basic bearing part around an axis of pitch and described seat support bearing part as follows radial type are connected, that is, described induce the forefoot area of described seat support bearing part by dorsoposterior oscillating motion lift motion.
Basic thought of the present invention is: the user of office chair comes oneself by backrest described in load and upwards lifts.In other words, user described lazy-tongs by overcome in the manipulation that pushes back backrest itself, the weight acting be placed on seat support.Desired swing resistance almost adjusts based on the weight of user thus voluntarily.Do not need known by prior art, for adjusting the elastic system and the Regulation mechanism (worm gearing, gear, threaded rod etc.) that expends that swing resistance (such as with the compression spring of multiple parallel connection or tension spring form).Carry out the manufacturing cost reducing lazy-tongs significantly thus.Improve reliability simultaneously.
Lever geometry for " self-adjusting " of the present invention mechanism realizes in the following way: the axis of oscillation of the connection of described backrest bearing part and described basic bearing part is after seat support longitudinal direction is arranged in the joints axes of the connection of described backrest bearing part and described seat support bearing part.
The number of component and then manufacturing cost are little especially because not only backrest bearing part and described basic bearing part, and described seat support bearing part and described basic bearing part directly, namely directly and do not have additional member in the middle of connects radial type be connected.
By the structural layout of structural detail, lift the forefoot area of described seat support bearing part when swinging described backrest.In the case, spacing between the forefoot area of described seat support bearing part and described basic bearing part becomes large, and the rear region of described seat support bearing part retains with described basic bearing part and is firmly connected.Carry out axis of oscillation that seat support connects around described seat support bearing part-basic bearing part backward thus with the inclination of one of the motion relative to the described backrest ratio limited.There is desired pull(ing) effect thus, wherein, described seat support bearing part is relative to the Angulation changes of described backrest bearing part.
The weight of user is directly to the swing resistance generation effect by the perception of user's energy.Lighter user must overcome swing resistance obviously less compared with heavier user when swinging.When swinging described backrest, subjective identical " feeling " resistance is obtained for each user.Can by adaptive to chair proposed requirement uniquely for being synchronized with the movement of described seat support bearing part by this layout in oscillating support and joint and the design of this layout.Therefore, it is possible to such as adjusted by the change of the spacing between leg supporting member or joint, how described seat support bearing part tilts to degree when described backrest swings.
Compared with the known solution of prior art, according to the present invention proposes better simply swing mechanism in a kind of structure, wherein, so-called " shirt pull-out effect " obviously reduces.In other words achieve extra high seat support comfortableness, and need not use comparatively expend and the solution of costliness.
Relative to other known " self-adjusting " structure, the characteristic of these lazy-tongs is, these lazy-tongs are flat especially structures, thus makes corresponding construction package only need considerably less installing space.Meanwhile, described mechanism builds extremely simply.Desired is synchronized with the movement and can realizes with three known parts and backrest bearing part, basic bearing part and seat support bearing part, and they are connected to each other by means of only three pin joints.
Accompanying drawing explanation
Explain with reference to the accompanying drawings below 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.
Detailed description of the invention
Whole accompanying drawings only schematically shows described lazy-tongs and with for the important part of 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 basic 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 a seat support bearing part 3 and fork-shaped in front view of frame shape substantially, and the curb girder 5 of described backrest bearing part is relative to two side arrangement of basic bearing part 1.Seat support bearing part 3 arranges the seat support face (not shown) for receiving or assemble preferred cushioning.Described assembling is carried out in a familiar manner by the tightening member be not shown specifically.Backrest bearing part 4 is mounted with the backrest be not shown specifically, and this backrest can carry out Height Adjustment when the office chair in modern times.Described backrest can be connected with backrest bearing part 4 also single type.
Whole lazy-tongs build with regard to relating to regard to actual kinematic middle fore-and-aft plane Mirror Symmetry.On this point, in the following description always from the structural detail that the both sides of actual swing mechanism occur in pairs.
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 is directly hinged on described basic bearing part, is exactly hinged in the first oscillating support 27 of basic bearing part 1 by supporting shaft 6.Seat support bearing part 3 can swing around the axis of oscillation 13 of transverse direction thus.In order to construct described oscillating support 27 in the region 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 oscillating support 27 is arranged in the rearward end 9 of described basic bearing part 1, so seat support bearing part 3 and/or seat support also can swing uninterruptedly, the trailing edge that they exceed described basic bearing part 1 stretches out, and need not for this reason special and structural measure expended.
Backrest bearing part 4 utilizes the curb girder 5 that seamed edge 8 extends before seat support to be directly hinged in the second oscillating support 28 of basic bearing part 1 by supporting shaft 6.Backrest bearing part 4 can be moved to by described home position in the position swung backward around the axis of oscillation 15 of transverse direction thus.Second oscillating support 28 observes the centre being roughly in basic bearing part 1 on seat support longitudinal direction 14, exactly direct before circular cone acceptance division 2.
Backrest bearing part 4 in addition also with seat support bearing part 3 directly radial type is connected, precisely assemble leg 19 with second of seat support bearing part 3, described second assembles leg is extended towards basic bearing part 1 downwards by the loading plate 11 of seat support bearing part 3.The elongated hole 20 be arranged in these the second assembling legs 19 constructs and rotates-arthrodia 16 together with the bearing pin 10 on the leading section of curb girder 5 being fastened on backrest bearing part 4.Backrest bearing part 4 and seat support bearing part 3 can swing around the joints axes 22 of a transverse direction thus and can be connected to each other movably on seat support longitudinal direction 14 simultaneously.In addition to rotary movement, in other words simultaneously also can translational motion by described joint 16.This is needs, to prevent from hindering described seat support bearing part 3, because backrest bearing part 4 is different around the tracks of the first axis of oscillation 13 from seat support bearing part 3 around the tracks of the second axis of oscillation 15.
Observe on seat support longitudinal direction 14 be arranged in by after backrest bearing part 4 being hinged on joints axes 22 that seat support bearing part 3 limits by backrest bearing part 4 being hinged on the second axis of oscillation 15 that basic bearing part 1 limits, thus make backrest on swaying direction 7 around the oscillating motion backward of the axis of oscillation 15 of the second oscillating support 28 induction of seat support bearing part 3 around the rotation of the axis of oscillation 13 of the first oscillating support 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 axis of oscillation 13 part (not shown) below that is in of seat support declines.
In other words, by the back lower place oscillating backrest seat support bearing part 3 being taken on swaying direction 7 and lifting based on the lever system that the curb girder 5 by backrest bearing part 4 is formed.Backrest bearing part 4 in basic bearing part 1 on and in seat support bearing part 3 on the position of pin joint 15,22 according to the lever element as integrated component part part of forefoot area of curb girder 5 that present invention defines backrest bearing part 4.
Spacing between first axis of oscillation 13 and the second axis of oscillation 15 and between the second axis of oscillation 15 and joints axes 22 defines the synchronized relation of described mechanism, that is, backrest bearing part pendulum angle 29 is relative to the transformational relation of seat support bearing part pendulum angle 30.Selected axis arranged determines the lever geometry of described mechanism, and defines seat support bearing part 3 and lift in which way and synchronously move with the backrest swung.
In embodiment illustrated in the accompanying drawings, the first axis of oscillation 13 and joints axes 22 are substantially on a height in the home position do not swung, and the second axis of oscillation 15 is only insignificantly arranged higher.Spacing 17 is such as only 2mm.Thus, the installation form of very flat structure is obtained in addition.
In a particularly advantageous embodiment, be 107mm and spacing 32 from from the first axis of oscillation 13 to joints axes 22 is 137mm by the first axis of oscillation 13 to the spacing 31 of the second axis of oscillation 15.The order of the layout of described axis 13,15,22 is not changed in the maximum position swung backward of described lazy-tongs yet.
Can set up to the second axis of oscillation 15 or the larger spacing 31,32 to joints axes 22 in mode simple especially in structure by the rearward end 9 that the 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 front seamed edge 8 of seat support bearing part 3.One embodiment proves advantageous particularly, and wherein, when backrest bearing part 4 has the swing 29 of roughly 25 ° to the back lower place, seat support bearing part 3 is roughly 5.5 ° relative to the inclination 30 of horizontal initial bit state.Under state after swing, be 11mm in the example that the vertical spacing 33 between the second axis of oscillation 15 and joints axes 22 draws in fig. 2.
The position of axis 13,15,22 is caused: total run-on point of described mechanism is a little agreed with actual swing of chair user approx when the oscillating motion of backrest starts.Obtain motion flow process comfortable especially thus and the appearance of negative effect, such as so-called shirt pull-out effect can be avoided.
Realize the mechanical features curve of approximately linear in this case, when this mechanical features curve, swing resistance approximate homeostasis in 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 backward is supported.
Ensured by described swing mechanism, be with backed backrest bearing part 4 can swing on swaying direction 7 around an axis of oscillation, the second axis of oscillation 15 described here.Side by side, that induces the forefoot area 26 of seat support bearing part 3 by dorsoposterior oscillating motion lifts motion 23.Seat support bearing part 3 moving forward or backward on seat support longitudinal direction 14 is not carried out at this in the swing of backrest to the back lower place.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 oscillating support 27,28 retention position.
Swing resistance to support to affect in other words and stop backrest controllably not tumbled backward and for once user's no longer load of backrest, backrest is by position the returning to the insurance in home position after swinging, and service has the elastic system of the one or more flexible member of a band.Such as relate at this elastic component 21 arranged in the region of front basic bearing part 18, this elasticity side is supported on basic bearing part 1 and opposite side is supported on the curb girder 5 of backrest bearing part 4, and this elastic component when swinging described backrest bearing part 4 by load.Flexible member 21 only needs weaker to construct, thus makes always only very little resilient force on the component of described mechanism, and this causes the stress of the obvious attenuating of described component in relatively conventional mechanism.
In the embodiment drawn in fig. 1 and 2:
A) described backrest bearing part 4 and described basic bearing part 1 connect by means of only with the unique direct of oscillating support 28 form;
B) described backrest bearing part 4 and described seat support bearing part 3 connect by means of only with the unique direct of joint 16 form; And
C) described seat support bearing part 3 and described basic bearing part 1 by means of only unique being directly connected, i.e. another oscillating support 13 and indirectly connect to connect by, wherein, described indirectly connection is set up by backrest bearing part 4, and this backrest bearing part is connected by described joint 16 with described seat support bearing part 3 on the one hand and is connected by described oscillating support 15 with described basic bearing part 1 on the other hand.
This embodiment is particularly advantageous, because therefore, it is possible to realize desired being synchronized with the movement with component few especially.But alternatively also it is possible that, substitute the joint 16 be integrated in described backrest bearing part 4, apply one or more coupling element to be connected on described seat support bearing part 3 by described backrest bearing part 4, their to be hinged on the one hand on backrest bearing part 4 and to be hinged on seat support bearing part 3 on the other hand.Thus the number of axis is brought up to four, obtain other possibility for the configuration that is synchronized with the movement thus.Still retain the basic structure obtaining described mechanism simultaneously, there is the mode of the motion particularly relating to described lever principle and seat support bearing part 3, feature above-mentioned.
All features shown in description, claim and accompanying drawing can be important to the present invention individually with in the mode of any combination with one another.
