Description
Technical field
The present invention relates to be used for the lazy-tongs of the relevant seat/backrest of office seating, described lazy-tongs comprise pedestal, and it can be placed on the seat post; Seat frame and back rest.
Background technology
Term " lazy-tongs " should be understood that the assembly in the seat minor structure of office seating, and described assembly has guaranteed to cause seat and backrest specific mobile coupling campaign respect to one another.The seat of office seating, the seat surface that it is typically provided with decoration is installed on the seat frame.Back rest, it extends back from the lazy-tongs of reality usually, with the back support of office seating on upwardly extending adjutage.Seat frame and back rest connect in hinged mode usually, and backrest moves (for example, this can lean to the backrest realization by the user) along the pivot of backward directions and causes that the trailing edge at seat moves along the decline of downward direction.
In order to change " pivotal resistance " of backrest, this lazy-tongs have the lazy-tongs of being used to substantially and apply prestressed spring structure.Prestressed size depends on seat user's weight etc. here.
Deutsche Bundespatent open source literature No.2026929 discloses a kind of seat with automatic adjustment backrest, in this case, the user leaning to backrest and thereby during along backward direction pivoting backrests, the rear section of seat panel will rise.This realizes that in the following manner the handle arrangement Rod end of back rest constantly abuts against the downside of seat panel.In the situation that present plane plate reduces, backrest moves forward.If the user is leaning to backrest, then the rear section at seat raises.
Summary of the invention
The purpose of this invention is to provide a kind of lazy-tongs, wherein need not to regulate elastic force, thereby change " pivotal resistance " of backrest.
This purpose realizes by the lazy-tongs according to claims.Therefore back rest, has been proposed, it can pivot around horizontal spindle, on the one hand be connected to pedestal, and be connected to seat frame via second connecting rod on the other hand, so that backrest moves along the rising that the pivot of backward directions moves the posterior region that causes seat frame via first connecting rod.Simultaneously, seat frame is connected to pedestal, moves so that finish the rising in the zone, front side of seat frame.
Basic thought of the present invention is, the user of office seating is by making backrest itself bear load make progress " rising " its oneself.In other words, by pushing backrest backward, when activating lazy-tongs, the user is sitting in the weight of resisting himself on the seat and operates.Thereby, because user's self weight is set up " pivotal resistance " of expectation in the automatic mode of standard.The elastic force adjusting device (Worm gear mechanism, gear, threaded rod etc.) that need not have any prior art of high cost governor motion.This has significantly reduced the manufacturing cost of lazy-tongs.Simultaneously, the fail safe characteristic of mechanism increases.
Because seat frame not only its posterior region raises, and simultaneously, its zone, front side also raises, thus the seat with respect to backrest synchronously along backward directions with upward to the degree of carrying to qualification.
An advantageous embodiment of the invention is pointed out in claims.
Particularly advantageously be, if pedestal is connected to the zone, front side of seat frame via the straight line guiding piece.In this case, the seat synchronously moves with the mode and the backrest of straight line.Except the guiding piece with rectangular guideway, other guide rail also is feasible certainly.The same moved further of seat frame can be adjusted individually by means of the structure of guiding piece and the position of guiding piece (for example, guiding piece is with respect to the angle of inclination of horizontal direction) etc.Thereby for example, seat frame can be in the mode of complete straight line at all without any synchronously move with back rest " perk ".Yet " perk " also can realize by means of the counter structure of guiding piece.Roughly obtain other remodeling by the tie point between pedestal and the seat frame away from the front side seat rim.
Layout and structure by two connecting rods can realize the required connecting rod geometry of " self-regulation " of the present invention mechanism, preferably, first connecting rod is provided with pivot bearings, so that the pivot that produces with respect to pedestal connects, an end of connecting rod is connected to seat frame in hinged mode, and the opposite end of connecting rod is connected to back rest in hinged mode.Seat frame and back rest be respect to one another to be moved thereby is defined by the position of four joint pins altogether, and wherein said joint pin extends through the end of described two connecting rods.Simultaneously, seat frame moves with respect to pedestal, be limited by the straight line guiding piece in the zone, front side of seat frame on the one hand, and position and the function by the pivot bearings on the first connecting rod is limited on the other hand.
Quite advantageously, if first connecting rod and/or second connecting rod are capped along outside direction by the part of back rest and/or the part of seat frame.The hiding arrangement of " in the inside " of lazy-tongs makes and can prevent that the dust for pivot from influencing and infringement.
Compare with the technical scheme that prior art is known, the present invention proposes a kind of pivot, it has simple and clear relatively structure, and significantly reduces " drawing shirt effect (skirt-pulling effect) ".In other words, need not to utilize expensive relatively and technical scheme expense, realize high level especially comfortableness.
Description of drawings
Referring to accompanying drawing, below the illustrative examples that present invention will be described in more detail, wherein:
Fig. 1 shows from the perspective view of the back lazy-tongs seen of skew back;
Fig. 2 shows the side view of the lazy-tongs that are in home position; And
Fig. 3 shows and is in the side view of the lazy-tongs of pivot position backward.
The specific embodiment
Institute's drawings attached has only schematically shown lazy-tongs, and it has according to component parts of the present invention.
Lazy-tongs have pedestal 1, and described pedestal is positioned on the top of seat post (not shown), as shown in Figure 1 by means of conical installed part 2.Lazy-tongs also comprise the seat frame 3 and the back rest 4 of frame shape basically, and described back rest is fork-shaped in vertical view, and the side member 5,6 of described back rest is arranged on every side of pedestal 1.The seat surface (not shown) that seat frame 3 is arranged to preferably to decorate can hold or be mounted thereto.Realize in a conventional manner installing by means of tightening member (not specifically illustrating).Be that adjustable for height backrest (not specifically illustrating) is sat idly on back rest 4 in the situation of modern handle official bussiness seat.Backrest also can be connected to back rest 4 integratedly.
As shown in the figure, for related actual motion, whole lazy-tongs are to be configured with respect to central fore-and-aft plane M mirror image symmetrical manner., in the following description, always take, the structural detail of actual pivot is provided with in pairs in both sides for this reason.
Fig. 1 and 2 shows home position, and wherein, back rest 4 is in the position of approximate vertical.Fig. 3 shows and is in the lazy-tongs of pivot position backward.
Can be connected to pedestal 1 along pivotal orientation S pivoting back rest frame 4 via first connecting rod 7 around horizontal spindle.First connecting rod 7 is provided with pivot bearings 8, so that the pivot that produces with respect to pedestal 1 connects.Connecting rod 7 is hinged on by means of bearing pin 9 on the side leg 11 of pedestal 1, and this side leg extends along the direction of rear side seat rim 10.A free end 12 of first connecting rod 7 is connected to the side arm 14 of seat frame 3 via hinge 13 in hinged mode, and this side arm extends along the direction of rear side seat rim 10.The opposite free end 15 of this connecting rod 7 is connected to the side member 5,6 of back rest 4 via hinge 16 in hinged mode, and this side member extends along the direction of front side seat rim 17.Here, the side arm 14 of back rest 3 extends in parallel with the side leg 11 of pedestal 1 and the side member 5,6 of back rest 4.Yet although side arm 14 and side member 5,6 are arranged to roughly align, side leg 11 is with respect to the direction biasing of side arm 14 edges towards the center of seat M.Thereby, first connecting rod 7 on the one hand, the side leg 11 of pedestal 1 and on the other hand, extend between the side member 5,6 of the side arm 14 of seat frame 3 or back rest 4.
Watch along vertical 19 of seat, first joint pin 18 that is limited by the bottom 15 that is hinged on the connecting rod 7 on the back rest 4 is placed in the rear of second joint pin 20, and wherein said second joint pin is limited by the top 12 that is hinged on the connecting rod 7 on the seat frame 3.First connecting rod 7 is roughly 5 ° at home position with respect to the angle [alpha] of horizontal direction.Same passablely be, be pivoted to maximum position backward at lazy-tongs, this order that joint pin 18,20 is placed does not change.In the position that pivots backward, as shown in Figure 3, first connecting rod 7 turns forward equally, although in this case, first connecting rod is in vertical direction with 12 ° angle beta roughly.In addition, vertically watch, first joint pin 18 always extends below second joint pin 20.
Should should be mentioned that once more that at this each parts of pivot are set to two.Yet for example, Fig. 1 only shows the first connecting rod 7 on the right side 23 that is placed in the seat, and the side member 6 of first connecting rod by back rest 4 that is arranged on the left side 24 at seat is hidden.
In addition, back rest 4 is connected to seat frame 3 via second connecting rod 25.First connecting rod 7 is longer than second connecting rod 25 a little.(rear side) first connecting rod 7 is approximately 1.07: 1 with the length ratio of (front side) second connecting rod 25.Here, a free end 26 of second connecting rod 25 is connected to the side arm 14 of seat frame 3 via hinge 27 in hinged mode conversely, and the opposite free end 28 of connecting rod 25 is connected to the side member 5,6 of back rest 4 in hinged mode via hinge 29.Watch along vertical 19 of seat, the 3rd joint pin 30 that the bottom 28 by being hinged on the second connecting rod 25 on the back rest 4 limits is arranged on the rear of the 4th joint pin 31, and wherein said the 4th joint pin is limited by the top 26 that is hinged on the connecting rod 25 on the seat frame 3.This means that at the home position of lazy-tongs, second connecting rod 25 also can lean to the front side, top, as shown in Figure 2 from end rear side.In this case, second connecting rod 25 is about 52 ° with respect to the angle γ of horizontal direction.Yet at pivot position backward, as shown in Figure 3, second connecting rod 25 leans to backward, be in the about 24 ° angle δ with respect to vertical direction, and first connecting rod 7 leans to forward still.In other words, in this position, the 4th joint pin 31 has moved to the rear of the 3rd joint pin 30 positions, that is to say, described the 4th joint pin is moved further along the direction of rear side seat rim 10.
The vertical arrangement of the joint pin 30,31 of second connecting rod 25 corresponds essentially to the vertical arrangement of the joint pin 18,20 in the situation of first connecting rod 7.Therefore, vertically watch, the 3rd joint pin 30 always extends under the 4th joint pin 31.
The vertical arrangement of four joint pins 18,20,30,31 of first and second connecting rods 7,25 is as follows: second basically is in identical height at home position with pivot position with the 4th joint pin 20,31.The pivot axle 21 of first connecting rod 7 is always extended between the height of the height of the second and the 4th joint pin 20,31 and the first and the 3rd joint pin 18,30.At home position, first joint pin 18 and at pivot position, is positioned at the 4th joint pin 31 belows between pivot axle 21 and the 3rd joint pin 30.
Described pivot guaranteed, can be around the pivot axle along pivotal orientation S pivoting backrests frame 4 and backrest.Simultaneously, backrest has caused the mobile H1 of rising of the posterior region 32 of seat frame 3 along the mobile S of the pivot of backward directions, as shown in Figure 3.In other words, along in the situation that is directed downwards pivot backward, back rest 3 priorities also move up at backrest, and pedestal 1 still is secured in place by means of pivot bearings 8.
In the region of first and second connecting rods 7,25, the side member 5,6 of back rest 4 and the side arm 14 of seat frame 3 contact in this zone, the bottom edge of side arm 14, this edge extends to front side, the end from the top rear side, seating is on the top edge 34 of the similar extension of side member 5,6 in the contact area that limits, and thereby the fixing home position of lazy-tongs.Rake is accompanied by along backward direction by such zone, in described zone, the free end 35 that roughly vertically extends of side arm 14 and the corresponding formation of side member 5,6 distolateral surperficial 36 toward each other.This arrangement has formed the covered structure of sealing, by means of described covered structure, is positioned at thereafter member structure and is protected and avoids dust and make dirty.Simple and clear additional covered structure, its form is that the side member 5,6 of back rest 4 extends upward, and can additionally even in the state that pivots prevent to touch pivot reliably.This allows to handle the high level security of office seating.
Simultaneously, seat frame 3 is connected to pedestal 1, thereby the pivot of back rest 4 has caused the rising campaign H2 in the zone, front side 37 of seat frame 3.In illustrative examples, lazy-tongs are configured to, the posterior region 32 of seat frame 3 raises a little more than the zone, front side 37 of seat frame 3 (H1＞H2), in this case, the position of the general planar of seat frame 3 in home position changes over the position that a little turn forward of seat frame 3 in pivot position.This has been avoided such situation occurring in the process that pivots, and promptly seat frame is cut undesirably or is pressed on the downside of thigh.At pivot position, back rest 4 has pivoted through about 24 ° pivoting angle ε with respect to pedestal 1, and seat frame 3 almost parallels raise.(among the H1＞H2), the posterior region 32 of seat frame 3 increases about 2 ° angle φ with respect to the zone, front side 37 of seat frame 3 in illustrative examples.
This structure means that when backrest bore load, not only the posterior region 32 of seat frame 3 was carried out the motion H1 that raises, and back rest 4 moves with carrying out backward to pivot along pivotal orientation S downwards.Also straight line rising in a synchronous manner of the zone, front side 37 of seat frame 3 (motion H2 raises).In other words, the front side of seat surface and rear side surface are raised simultaneously.Whole seat raises.
Lazy-tongs also comprise spring element, described spring element the home position approximate horizontal be arranged in the seat frame 3, and form is a tensioning spring 41, described spring is connected to the bearing spindles of pedestal 1 on the one hand, and is connected to the maintenance axle 42 of the additional lateral arrangement on the seat frame 3 on the other hand.The anterior end of tensioning spring 41 is assemblied on the bearing spindles, and its rear end is assemblied on the maintenance axle 42.Tensioning spring is applied in prestressing force along the home position direction of lazy-tongs.At home position, be arranged in maintenance axle 42 between the side leg 11 of pedestal 1 be positioned at the roughly the same height of bearing spindles and the second and the 4th joint pin 20,31 on.At pivot position, keep axle 42 by seat frame 3 along backward and the direction that makes progress carrying, and be positioned at equally then with the roughly the same height of the second and the 4th joint pin 20,31 on.Here, the spacing between bearing spindles and the maintenance axle 42 increases, and tensioning spring 41, edge direction backward leans to then, bears further stress and applies.This spring stress helps backrest to turn back to home position from pivot position.Except single tensioning spring, depend on the load of the imagination of seat, can also use parallel a plurality of tensioning springs or other spring element.For the fixing gradient of backrest, be provided with and do not specify but can be operable to the mechanism that helps to activate the rod member (not shown).
