Description
Technical field
The invention belongs to furniture technical field, be specifically related to a kind of furniture underframe for sitting posture/horizontal furniture.
Background technology
The furniture underframe of sitting posture/horizontal furniture is used for sitting and lying formula furniture, such as, couch before movable reclining chair, television set etc., and chair can be adjusted to clinostatism or be adjusted to seat from clinostatism from seat.On such sitting posture/horizontal furniture underframe, can corresponding sitting posture/horizontal furniture be installed with different designs, because underframe has a kind of bearing support, the parts such as spike, footrest rack, seat frame, backrest and the handrail of furniture can be installed in the above.When using sitting posture furniture, first by an adjusting transmission device to these furniture parts, for example footrest rack is adjusted, as outside swing, this and by the adjustment that Vidacare corp in-built in sitting posture furniture carries out sitting posture furniture, moved relevantly, or complete by means of the mobile body weight that is sitting in the people on sitting posture furniture.Such footrest rack deflects to so-called retracted position or position at an angle under sitting posture/horizontal furniture completely.In the position outwards swinging, before footrest rack is positioned at sitting posture/horizontal furniture underframe, substantially with bearing-surface extend into straight line or curve.In addition, footrest rack also can be furnished with a kind of so-called footrest rack extension element, in retracted position, can be drawn in footrest rack, also can be in withdrawn position by it from extracting out and be used for extending effect in footrest rack.
For the furniture underframe of sitting posture/horizontal such furniture, known from German utility model 29600282UI.For the sitting posture furniture of describing in this patent, seat frame is a part for parallel steer system, with this, can make the support of sitting posture furniture move to clinostatism from seat.Now, upper longitudinal turning-bar of parallel steer system forms or carrying seat frame, and its lower longitudinal turning-bar is fixing in substructure side.Footrest rack comprises two guide rails, and by these two guide rails, footrest rack is connected on seat frame in turnover mode.On this sitting posture/horizontal furniture, by the guide rail of footrest rack, form the horizontal turning-bar before seat frame, thereby the guide rail longitudinal turning-bar that is fixed on bracket side also and is below hinged equally.The movement of seat frame from seat to clinostatism, can cause the footrest rack of the inside swing in resting position below seat frame outwards to swing.Footrest rack, in one side, supports a footrest rack element moving along guide rail y direction, thereby forms the closure of footrest rack.In view of guide rail, removable and telescopic layout, the footrest rack relevant from footrest rack element stretching distance has different length.The position inwardly swinging at footrest rack draws in footrest rack element, can below seat frame, inwardly swing.If the clinostatism that sitting posture furniture outwards swings in footrest rack, pulls out footrest rack element to increase the length of footrest rack.
The furniture underframe of such another sitting posture/horizontal furniture is learnt from patent EP2356922A1, wherein the gyration of footrest rack is linked togather by the motion of a buffer cell and seat frame, and by one, supports retaining spring hold mode at the footrest rack of retracted position.In view of the cooperation between design and longitudinal turning-bar, vertical lever and the seat frame of longitudinal turning-bar and vertical lever is without sufficiently stable terminal location, from forming the kinematics configuration this respect for seat or clinostatism, this additional buffer cell and supporting retaining spring are very necessary for the parallel steer system of structure sitting posture/horizontal furniture underframe.The dead weight that changes seat frame and footrest rack by being sitting in or lying in people on sitting posture/horizontal furniture may produce such consequence: on the contrary loading within the scope of footrest rack can cause that seat frame moves unintentionally or.
Summary of the invention
According to above-mentioned prior art, the present invention continues to design the furniture underframe of a kind of sitting posture/horizontal furniture, object is: for causing the dead weight of seat frame and footrest rack to change by being sitting in or lying in the people on sitting posture/horizontal furniture, the present invention can reach preventive effect to the kinetic characteristic of sitting posture/horizontal furniture underframe.
In order to realize foregoing invention object, the technical solution used in the present invention is as follows:
The furniture underframe of sitting and lying formula furniture, this furniture underframe comprises bearing support and the seat frame with backrest, seat frame is arranged on bearing support movably by a quasi-parallel steering; Described quasi-parallel steering consists of bearing support, seat frame, the first rocking bar and the second rocking bar, seat frame is being moved between seat and the terminal location of these two states of clinostatism, wherein, the hinged formation rear side of the first rocking bar and bearing support fulcrum, the hinged formation of the second rocking bar and bearing support front side fulcrum; The position of described rear side fulcrum and front side fulcrum makes seat frame: when in clinostatism state, people's self gravitation puts on the rear of rear side fulcrum and front side fulcrum and acts on seat frame along backrest direction, when in seat state, people's self gravitation is applied to the front of rear side fulcrum and acts on seat frame.
When furniture underframe moves between seat and clinostatism, on bearing support, design and be furnished with the rear side fulcrum of nearly backrest and the front side fulcrum of nearly chair end for the quasi-parallel steering of seat frame, the synthetic gravity that makes to lie in clinostatism the people on sitting posture/horizontal furniture is applied on the backrest being positioned on seat frame after fulcrum, otherwise in seat, the synthetic gravity that is sitting in the people on sitting posture/horizontal furniture be applied to rear side fulcrum on seat frame before.During clinostatism, the rocking bar of quasi-parallel steering is turned over along backrest side always, after making the hinged rear side fulcrum that is positioned at seat frame of seat frame on these rocking bars, and therefore occupying a stable terminal location, this is spacing can consist of a block being fixed on accordingly on bracing frame.While being adjusted to seat, seat frame must be adjusted to a position of the top dead-centre of crossing quasi-parallel steering, the synthetic Action of Gravity Field that is sitting in people on sitting posture/horizontal furniture in this position be positioned at rear side fulcrum on seat frame before, thereby drop between the rear side fulcrum and front side fulcrum of seat frame.Therefore, again need here to realize definition and the stable final position of mechanics for seat by a for example corresponding block.Guarantee thus, two final positions, do not need the effect of the fixing or power of adding as spring pre-tightening or similar setting, to keep reliably the posture of seat frame to fix in these two positions.Like this, lie in or be sitting in the slight of people on sitting posture/horizontal furniture, weight shifts and just can not cause seat frame to be adjusted to the position not being inconsistent with people's wish of recumbency/be seated unintentionally or rather.Even while particularly having additional support in people's foot, because of footrest rack collapsible, the adjustment movement of the mode that this footrest rack is known with self and seat frame is linked togather, and only has slight loading to act on seat frame by footrest rack, and this likely causes the movement of undesirable seat frame.By design of the present invention, can guarantee to stop this situation to occur, and not hinder the adjustment of the seat frame that user wishes.
Special advantage of the present invention is, while adjusting between seat and clinostatism, the seat frame of sitting posture/horizontal furniture underframe keeps a unsettled poised state, now synthetic Action of Gravity Field of people that lies in or be sitting on sitting posture/horizontal furniture passes through the rear side fulcrum of seat frame just, this point is the top dead-centre about the quasi-parallel steering of seat frame rear side fulcrum, thereby make seat frame conventionally can not rest on this unsettled poised state, and be for clinostatism or be to regulate for the mobile terminal of seat, then reach mechanics stable.Another advantage is, if forming respectively seat frame between it, seat and clinostatism regulate mobile stable terminal location, wherein for the position of seat frame quasi-parallel steering respectively by the stop limits being fixedly connected with bearing support, on the corresponding member being fixed on bearing support, for example longitudinally on turning-bar or similar component, fastening these blocks are being set, for example by rocking bar, interact, make it some full swing angle of the rocking bar that can only realize regulation.
The present invention further improves, by the front horizontal support pipe of seat frame and rear horizontal support pipe respectively by the hinged support of being fixed on the longitudinal turning-bar that forms quasi-parallel steering of rocking bar.At this, seat frame supports in the whole length of seat frame as a part for quasi-parallel steering, can obtain the particularly advantageous power importing/supporting role of seat frame thus at its terminal location.The rear side fulcrum that is arranged on member on bearing support and formation is positioned at the lower zone of the horizontal support pipe of seat frame backrest side.Whereby, because longitudinal turning-bar has larger length and the corresponding distribution of weight that acts on the gravity on seat frame and backrest, this gravity is from the deadweight of sitting posture/horizontal furniture, and due to sitting posture/horizontal furniture user's weight, reaches best lever transmission ratio.Improve in this way the lever transmission ratio between seat frame front side fulcrum and rear side fulcrum, make it needn't adopt other servicing unit, for example spring or like, to keep the mechanics safety of seat frame in seat and corresponding two terminal locations of clinostatism with stable.
Otherwise sitting posture of the present invention/horizontal furniture underframe can be only by by the weight that is sitting in or lies in the people on sitting posture/horizontal furniture, shifted from seat switch to clinostatism or, or by additional driving mechanism, the preferably driving mechanism of electronic or hydraulic pressure, on the contrary by seat frame from seat switch to clinostatism or.In addition, can also use motorized adjustment or the manual adjustment by the resiliency supported of air spring.
With regard to the people's that is being seated/crouching comfortableness, the front side fulcrum of seat frame is vertically arranged higher than the rear side fulcrum of seat frame.When seat, the seat frame surface for taking a seat, along the adjusting that recedes a little of backrest direction, meanwhile, depending on the length of rocking bar and the geometry of quasi-parallel steering, also can be increased to the reverse gradient of clinostatism, thereby makes clinostatism more comfortable.
The further improvement project of the present invention is, on seat frame, configure by known methods a toe board with leg rest framework, this framework can be round the steering spindle revolution substantially parallel with the front horizontal support pipe of seat frame, and can keep relative distance adjustment with seat frame by push rod, push rod and quasi-parallel steering enter into closed position with toe board, seat frame just becomes sitting posture state, enter into the position of opening, seat frame just becomes lying status, leg rest framework links together by push rod and quasi-parallel steering, the position of the outside swing when retracted position when toe board is positioned to seat from seat frame deflects to seat frame and is positioned at clinostatism.A telescopic extension element is set in leg rest framework, and toe board extension element under open mode is parallel to be extended along framework.Only have when leg rest framework is in the process from inside to outside swinging, when its framework end distance overhead exceedes minimum of a value, push rod just can drive extension element to do extension action.If the lower end of leg rest framework does not also arrive minimum point, the extension of extension element can hinder the outside swing of leg rest framework, also can reduce thus the structure height of bearing support.
For this reason, in further scheme, the overhanging transmission device of leg rest framework extension element is a curved bar transmission device, when toe board is outwards opened while doing very little swing angle doing, the corresponding prolongation extension element of curved bar transmission device does very little linear over reach, when leg rest framework outwards compares large swing, curved bar transmission device just drives whole toe board to do corresponding larger over reach to extension element.When the low spot of footrest rack framework exceedes the minimum point of gyration step by step, by the respective design of curved bar transmission device, start targetedly mobile footrest rack extension element.Subsequently, can be by such curved bar transmission device when respective design lever length and the swivel point, guarantee the enough adjustment length of footrest rack extension element, footrest rack stretches out the front side of seat frame far away thus, almost in its whole length, can provide comfortable support for leg/pin of user.In addition, also linear guides, particularly roller guide can be passed through and can guide the overhanging movement of footrest rack extension element.By the power of transfer function on sitting posture/horizontal furniture underframe in phase, can avoid using common and expensive ball extensible track here, replace with roller guide cheaply.Furniture underframe of the present invention can mobile footrest rack without buffer cell or supporting retaining spring in the situation that.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further details.
Sitting posture of the present invention/horizontal the furniture underframe presenting is in the accompanying drawings the structure in the situation that not serving as a contrast cushion and outer cover, can help us to be familiar with better its member and function, Basic Design and function aspects can be known from the present art, therefore be not only the cooperation of member about using or its how much and function here, only illustrate for special performance and for this reason necessity structure and for the description of its function necessity.Other side is referring to from the known sitting posture of the present art/horizontal furniture underframe 1.Sitting posture of the present invention/horizontal furniture underframe 1 is the underframe of such a type, itself and bearing support 2 together adaptive different spike, for example by installing plate 11 and standpipe 12, formed, simultaneously also have a seat frame 3, it can clamp and/or handle do not continue to illustrate, can backrest and the toe board 4 of attaching on flange 10.With identical and same or similar parts similar functions, has been furnished with same datum symbol.Concept " above " refers to the front of sitting posture in the scope of toe board 4/horizontal furniture underframe 1, now concept " below " refers to the back side of sitting posture in unshowned backrest/horizontal furniture underframe 1, and this backrest can be set to mobile or fixed for seat frame 3 on corresponding flange 10.
Sitting posture/horizontal furniture underframe 1 is supported on spike by the installing plate 11 on base and standpipe 12, and on top, there is a forked bearing support palette fork 13, on it, the longitudinal turning-bar 7 of two tubuloses on two forks of bearing support palette fork 13 extends forward along the direction of toe board 4.Two side arrangement and be fixed on longitudinal turning-bar 7 on bearing support 2 above, can find out that seat frame 3 is essentially rectangle from a complete pipe frame structure, now two of seat frame 3 longitudinal bracing pipes are roughly parallel with longitudinal turning-bar 7, and together with two terminal is connected to each other with horizontal support pipe 26,27 respectively.Seat frame 3 use cushion support springs 17 have formed bearing, and this bearing for forming the unshowned seat cushion of sitting posture/horizontal furniture together with sitting posture/horizontal furniture underframe 1.Below seat frame 3 these one decks, from zone line to the central area of front horizontal support pipe 26 of rear horizontal support pipe 27, can recognize diagonal brace 8 tubulose and repeatedly bending, this diagonal brace impels seat frame 3 to reinforce, and what reinforce, use and can arrange two flanges 18, they can be used for the electronic adjustment of unshowned for example seat frame 3.
Seat frame 3 and two longitudinal turning-bars 7 form a quasi-parallel steering together with middle brace rod 32 together with rocking bar 14,15, by this system, the clinostatism shown in seat frame 3 can being amplified from Fig. 1 is adjusted into the seat shown in Fig. 6.Now, can be by before being tilted to and the longitudinal turning-bar 7 of layout stretching upwards and according to rocking bar 14,15 length, according to the ergonomics layout that easily seat frame in seat 3 and unshowned backrest receded, the gradient of the seat frame of the clinostatism of seeing in Fig. 13 is amplified with respect to seat simultaneously.
The concept of quasi-parallel steering shows, it is a steering having made an amendment compared with pure flat row steering, rocking bar 14 not only in this system, 15 length can change, and their geometry and bending also can change, but the basic geometry of quasi-parallel steering still remains unchanged in principle.
Here, relative two longitudinal turning-bars 7, seat frame 3 is capable of regulating by the hinged rear side fulcrum 9 of backrest side and the hinged front side fulcrum 33 of toe board side and arranges, hinged 9, rotatable arrangement rocking bar 14 in 33,15, and directly or by middle brace rod 32 and seat frame 3 be hingedly connected together at its other end.Seat frame 3 can be carried out the gyration of extending around two hinged supports 9,33, and during motion due to lever length and the lever transmission ratio of rocking bar 14,15, the inclination of seat frame 3 becomes clinostatism from seat, increases to some extent as mentioned above.It is limited that seat frame 3 to the adjustment of clinostatism moves through a block 16 above, to this, when the rocking bar 15 shown in Fig. 1 moves right, stops.On the contrary, seat frame 3 to the adjustment movement of seat is carried out the block by backrest side 31 spacing, to this, when the rocking bar 14 shown in Fig. 1 is moved to the left, stops.Therefore, these two blocks 16,31 have defined the revolution range allowing when seat frame 3 moves between seat and clinostatism.
These descriptions are only done in particularly advantageous design about sitting posture according to the present invention/horizontal furniture underframe 1, due to the geometry of quasi-parallel steering member, with without other supplementary means control fulcrum 9,33 position, seat frame 3 keep clinostatism or seat constant, be adjusted into stable clinostatism or seat.Therefore, when clinostatism, lie in the synthetic Action of Gravity Field of the people on sitting posture/horizontal furniture after backrest direction puts on the fulcrum 9 and 33 on seat frame 3, otherwise, during seat, the synthetic Action of Gravity Field that is sitting in the people on sitting posture/horizontal furniture put on backrest side on seat frame 3 fulcrum 9 before.As shown in the figure, during clinostatism, the rocking bar 14 of quasi-parallel steering, 15 turn in backrest side always, make seat frame 3 at rocking bar 14, after the hinged fulcrum 9 that is positioned at seat frame 3 backrest sides on 15, thereby occupy a stable terminal location, it is spacing can consist of a corresponding block 16.While being adjusted to seat, must adjusting seat chair frame 3 to a position, place of crossing quasi-parallel system top dead-centre, in this position, the synthetic Action of Gravity Field that is sitting in the people on sitting posture/horizontal furniture fall within backrest side fulcrum 9 on seat frame 3 before, thereby between the backrest side fulcrum 9 of seat frame 3 and front side fulcrum 33, work.Thus, again reach definition and the stable terminal location of mechanics for seat by a corresponding block 31.Therefore, need guarantee, the fixing or power that does not need to add at these two terminal locations be used for keeping seat frame 3 in this two positions time posture constant, for example spring pre-tightening or similarly power.Like this, lie in or be sitting in the slight of people on sitting posture/horizontal furniture, weight transfer can not cause unintentionally or rather, seat frame 3 is not intended to move to the position not being inconsistent with the people's of recumbency/be seated intention, even while particularly having additional support in people's foot, on a folding toe board 4, this toe board is linked togather with the mode known and the adjustment movement of seat frame 3, only have slight loading to act on seat frame 3 by toe board 4, this likely causes the movement of less desirable seat frame 3.By design of the present invention, can guarantee to stop this situation to occur, and not hinder the adjustment of the seat frame 3 that user wishes.
Seat frame 3 is from shown in Fig. 1, and the clinostatism that meets the illustration in the middle of Fig. 2 moves to the seat of seeing in Fig. 6, and this process can clearly be identified and understand from Fig. 2 to Fig. 6, therefore no longer continue to study in great detail each free hand drawing here.
On this sitting posture/horizontal furniture underframe 1, with the adjustment configuration of lever 21,22, for by the mobile involuntary conversion of seat frame 3 to toe board 4.Lever 21,22 has steering spindle 20,35 level or level of approximation separately, and respectively has one end to be connected with the movement of quasi-parallel steering, directly or indirectly by one or more executing agencies, connects.Now, lever 21 is responsible for the deflection of leg rest framework 5 around steering spindle 20, and steering spindle 20 is fixed on seat frame 3 by flange 19.In at Fig. 2 to Fig. 5, see, leg rest framework 5 turns to clinostatism (Fig. 2) from seat (Fig. 6), the position, this position and the base approximate horizontal that below seat frame 3, out to it, stretch.In seat, in contrast, leg rest framework 5 completely inwardly upset layouts below seat frame 3.
Overlapping with the gyration of leg rest framework 5, can, with respect to an extension element 6 being arranged in footrest rack framework 5 of leg rest framework 5 linear pull-outs, compare and extend toe board 4 with the length of inwardly upset whereby.For this reason, in the outside of leg rest framework 5, arrange some rollers 24, on roller, can guide the guiding section bar 25 of adjusting C type.The linearity adjustment that causes leg rest framework extension element 6 by the driving of a curved bar structures is moved, and this driving consists of some single levers 28,29,30.When utilizing lever 22 moved seat framework 3, in the mode of substantially knowing, driven.To this, by articulation steering axle 35, lever 22 is connected and is combined together with a kind of mode that does not continue to illustrate of lever 29 use that curved bar drives.If as mentioned above, seat frame 3 is adjusted to clinostatism (Fig. 2) from seat (Fig. 6),, only by adjusting seat chair frame 3, both can outwards swing leg rest framework 5, also can shift out from leg rest framework 5 neutral lines the extension element 6 of leg rest framework.
In Fig. 7, also amplify again the feature of having shown, owing to having used curved bar to drive and its physical dimension and the position of this curved bar driving swivel point, only when leg rest framework 5 is deflecting to from seat that clinostatism reaches or when relating to the track deepest point of underframe, substantially could be from leg rest framework 5 out, start to adjust the Linear-moving of leg rest framework extension element 6.If the linearity adjustment of leg rest framework extension element 6 is moved in advance, start, must increase as much as possible the road clearance of sitting posture/horizontal furniture underframe 1, thus make the outside swing of leg rest framework extension element 6 and when overhanging its end can not bump against with base.Perhaps can cause thus the uncomfortable or leg rest framework extension element of seating state 6 must be limited, to this, compared with the length that can reach, need totally to shorten toe board 4, thereby also need to shorten the bearing-surface for leg.Curved bar drives and allows in this case the exercise performance of leg rest framework extension element 6 to carry out the simple adjustment of one, because the kinetic characteristic can respective design curved bar driving, when exceeding a small amount of linearly moving scope of curved bar driving, allow to move enough haul distances for linear adjustment of leg rest framework extension element 6 simultaneously.
