For example, this spring energy storage device 15 constitutes a part of this support 12.For example, this spring energy storage device 15 is arranged on the form of cross bar between two vertical support or pillar 16 of support 12.Pillar 16 is erected on the leg 17.Leg 17 forwards stretches out, so that has constituted C type leg.But T type leg equally also it is contemplated that.Pillar 16 is vertically adjustable, and is advantageously for example flexible for estable, becomes possibility so that the height of working plate 11 is regulated.Top column piece 19 is directed at bottom column piece 18 places of pillar 16.Advantageously, be fixed with basic frame (Korpus) 20, exemplarily demonstrated the side plate (Seitenwangen) 21 in this basic frame 20 at top column piece 19 places.

Working plate 11 is regulated with respect to basic frame 20 tiltables, and wherein, this tilt adjustment device does not illustrate.Basic frame 20 also can have other element, and for example unshowned drawer or other can be extracted element out.Therefore on this furniture 10, this basic frame 20 can integrally-regulated height together with the working plate 11 that is provided with thereon.

Spring energy storage device 15 and mobile member 14 connect versatilely via transmission mechanism 22.Current, pillar 16 can for example be made by metal (as metallic plate) and/or plastics.Pillar 16 inside are hollow.Just produced structure space thus, in this structure space, transmission mechanism 22 can be set respectively.For example, in furniture 10, this transmission mechanism 22 is arranged in the column 16 on the right side among Fig. 1, and be positioned at shielded, for operating personnel can't be approaching inner chamber 23 in.

The linearity that transmission mechanism 22 will be taken place in member 14 is highly regulated moves to convert to and rotatablely moves, and is used for storing elastic force in spring energy storage device 15.On the direction of opposite power, spring energy storage device 15 is emitted moment of torsion to transmission mechanism 22, and this transmission mechanism 22 changes this torque axis into linear force in the sensing, supporting member 14.

The one or more actuators that are fixed on the top column piece 19 pass from the vertical channel 25 of bottom column piece 18, and are connected with chain 26.Actuator 24 for example is a bolt, and it is inserted saturating from the eyelet of top column piece 19 and crosses and screw in the driver part 27 of chain 26.Driver part 27 also is configured for the chain button of chain 26.

Chain 26 is around lower pinion and

upper pinion

28,29 and rotate, and this lower pinion and

upper pinion

28,29 are placed on the vertical supporting member 30 rotationally.This vertical supporting member 30 for example is tabular, for example, plate, these plates interconnect by horizontal connecting rod 31.

Pinion

28,29 is sandwiched between the supporting member 30.Advantageously, be adjustable at least one the pinion vertical direction in two

pinions

As recited above, can only be provided with transmission mechanism 22 in the pillar in two pillars 16.Hereinafter, will be as an example from following situation, that is, in two pillars 16, respectively be provided with transmission mechanism 22.

Spring energy storage device 15 all has power transmission with two transmission mechanisms 22 and connects.Plug 34 is inserted in the accommodation section 36 of the accommodation section 35 of lower pinion 28 and spring energy storage device 15, to realize the antitorque connection of unit.

The accommodation section 36 that constitutes the portion of putting forth effort is set at the place, end of the turning cylinder 37 of spring energy storage device 15.Turning cylinder 37 stretches on the longitudinal extension direction of spring energy storage device 15, and is placed in rotationally on the housing 39 of same spring energy storage device 15.The

longitudinal end

40,41 of turning cylinder 37 is placed on the

bearing

42,43 of housing 39

rotationally.Bearing

42,43 is arranged in the

cover

44,45, and each is closed this

cover

44,45 since the mid portion 46 of a side with housing 39.This mid portion 46 is the die casting for being made by die cast metal for

example.Cover

44,45 for example utilizes bolt 47 and is tightened on this mid portion 46.

Turning cylinder 37 is configured for the bar-shaped supporting device 48 of the helical spring 49 of spiral spring device 50.Supporting device 48 penetrates and mistake from the inner chamber 89 of helical spring 49.When controlling this mobile member 14, in order to store elastic force, by transmission mechanism 22 linearity of this mobile member 14 is moved to convert to and rotatablely move and it is delivered on the spiral spring device 50.Helical spring 49 is fixed at one end on the housing 39 antitorquely and is fixed on the turning cylinder 37 at other end place antitorquely.For example, first longitudinal end 51 of helical spring 49 is fixed on the holding device 53 antitorquely, then is connected with turning cylinder 37 in the zone of its second longitudinal end 52 antitorquely, and this holding device 53 can be fixed with respect to housing 39 antitorquely.Therefore, rotatablely moving of turning cylinder 37 causes reversing of helical spring 49, and this helical spring 49 is bearing on the holding device 53.

When such reversing taken place, helical spring tended to wavy deformation occur in principle, that is to say, perpendicular to the deformation of longitudinal extension direction 38, in other words perpendicular to the deformation of bar-shaped supporting device 48.Supporting device 48 can limit this wavy deformation, wherein, in current situation, helical spring 49 versions (itself also being independently to invent) can play resistant function to this corrugated deformation, and are provided on this supporting device 48, stable and rotating supporting in particular.

The effect of the gantry post device 54 of spiral spring device 50 is to be implemented on the bar-shaped supporting device 48 and/or the supporting on turning cylinder 37.The effect of reversing spring coil section 55 of spiral spring device 50 is to absorb reverses and/or emits stored elastic force.Gantry post device 54 comprises the supporting spring coil section 56 of helical spring 49.Compare with the spring coil 58 of supporting spring coil section 56, the spring coil 57 that reverses spring coil section 55 has bigger diameter.

Advantageously, the spring coil 58 of supporting spring coil section 56 is wound into piece in addition, that is to say, when this helical spring 49 does not bear torsional load or only bears torsional load in its common pre-tensioned scope, these spring coils 48 are touching mutually---and extract position (promptly in the upper position place of Fig. 1) out when this mobile member 14 is arranged in it, and this helical spring 49 has just had this pre-tensioning.In contrast, spring coil 57 reciprocally alternate in the axial direction separating on longitudinal extension direction 38.

When absorbing twisting resistance, the degree that the interior cross section of supporting spring coil section 56 is not shunk or shunk is quite little, so that should supporting spring coil section 56 can freely rotate on this supporting device 48 and/or turning cylinder 37 basically.Therefore,, can freely rotate basically though this helical spring 49 guides by this supporting device 48, to such an extent as to can not produce undesirable friction loss, and this spring energy storage device 15 is blocked.

Improve the sliding that supports spring coil section 56 by sliding members 59, this sliding members 59 is arranged on supporting spring coil section 56 inner peripherys 60 places separately.This sliding members 59 can be for example for being inserted into the plastic bushing in this supporting spring coil section 56.
