Definitions
- the invention relates to a rear part of device according to claim 1 and a chair with a rear part device according to claim 14.
- the invention relates in particular to a pendulum-back device with an elastically deformable joint body for seating with a seat and a column for exerting pendulum movements of the seat, wherein the spring characteristic and thus automatically adjusts the restoring force of the rear part device depending on the body weight of the seat occupant.
- the rear part of the invention can be used for all applications in which a lateral restoring force in a lateral deflection should be adjustable in weight.
- An advantage of a device for automatically adjusting the spring characteristic and the resulting restoring force is the avoidance of too large or too small deflection width of a pendulum seat.
- a generic seating or a pendulum chair is known in which a rear part device, in particular for a bar stool with a seat part, an intermediate part and a foot part is disclosed in which the intermediate part is resilient and tiltable and resettable on the foot is stored. Furthermore, a movable seating furniture of the type mentioned with a restoring device at its foot also from the European patent EP 0808116 B1 is known.
- This rear part device is designed so that the restoring force can be set individually by means of an adjustable screw actuated by the seat user. This makes it possible for the seat occupant depending on his body weight to adjust the pendulum deflections and the restoring force of the pendulum joint by means of the adjusting screw.
- this setting can only be made if the seat occupant does not use the chair. Rather, the user must get up from the pendulum stool, this um- Turn and then use the adjusting nut to increase or decrease the return force until the correct setting has been found.
- Another disadvantage is that the one-time setting of a seat occupant for another seat occupant with different body weight does not fit and this must adjust the setting to his needs.
- the seat users are not easily aware that such an individual attitude with respect to their body weight and the matching restoring force is provided at all.
- the amount of deflection in pendulum movements is fundamental to the use of a pendulum stool. If the restoring force is set for a person with a specific body weight, then a person of lesser weight can deflect the seat only with difficulty. As a result, the seat does not tip forward as it turns, and the positive effect of tilting the pelvis forward and thus avoiding circling does not occur.
- a chair with a seat and a pendulum device for exerting pendulum movements of the seat with a device for automatically adjusting the pendulum restoring force depending on the weight of a person using the seat has a seat, a strut, a foot, and a pendulum device and a device for automatically adjusting the pendulum restoring force.
- This seat is designed so that is extended by deeper sinking of the seat supporting shock absorber at a higher body weight of the user, the lever arm in a lower bearing of the center column, whereby the resistance of the lateral deflection increases with increasing body weight of the seat occupant.
- the device has a complex structure. There will be one bearing housing, several in the
- the device has a helical spring on which the control is supported. Depending on the body weight of the seat occupant and the spring rate of the screwdriver.
- a disadvantage of the reset device from DE 10 2009 019 880 A1 is that it uses a screw (pressure) spring as the means for regulating the penetration depth and this predominantly generates a restoring force in the axial direction. Depending on the depth of penetration, different bending moments result and the axially actuated coil spring is also twisted. Furthermore, the reset device is complex and their properties are determined by the interaction of the various mutually movable Bau-> - parts. Due to the relative movement between the control and the rubber bearings, it can also lead to mechanical abrasion.
- a lateral (lateral) restoring force generating element is formed as an elastically deformable or deformable molded part, which has one or more recesses and / or cavities, which are shaped such that the pendulum column the pendulum chair depending on the body weight of the seat occupant deformed the molding more or less strongly, thereby reducing the recesses and / or cavities in their volume and thereby the flexural rigidity is increased.
- the directional spring characteristic of the molded part is changed.
- the restoring force automatically sets itself accordingly.
- the chair leg end cooperating with the molded part, which is received in the molded part and fastened there, is completely surrounded by the molding material.
- the molding material used is preferably an incompressible to slightly compressible material.
- the basic idea of the present invention is thus to provide an elastically deformable molded part made of a molding material (material) whose Poisson's ratio (transverse contraction number) is preferably between 0.44 and 0.5, close to 0.5 or particularly preferably 0.5. This ensures that the elastic "see deformation mainly due to the recesses, such as gaps or voids can be achieved.
- the elastomers, rubber, rubber, silicones, TPE or NBR are suitable molding materials for forming the molding.
- Elastomers consist of long-chain macromolecules that are cross-linked by covalent primary bonds and distributed randomly. On the degree of crosslinking and the degree of polymerization, which is a measure of the length of the macromolecules, the material properties such as strength and the spring characteristic can be adjusted. The distance between the crosslinking points, which is the length of a free chain segment, is 5-20 carbon spacings. Due to the crosslinking, elastomers are not plastically moldable. In the unclaimed state, the macromolecules are strongly entangled due to the rotatability about their axis of attachment between the chain links. Their orientation in space is undirected. This is the state of highest entropy and thus the statistically most likely equilibrium state at service temperature, whereby elastomers have an amorphous isotropic structure.
- This effect is used according to the invention that through the training suitable recesses and cavities in the molded part, a desired axial and preferably dependent lateral restoring force can be generated.
- the effective lever arm of the chair leg can be shortened and the lateral spring characteristic can be set automatically; b) Furthermore, the body weight-dependent deformation of the molding material into the recesses limits the mobility of the chair leg in the molding material in accordance with the degree of deformation.
- the invention therefore provides a return device for a pendulum chair for automatically adjusting the spring characteristic and thus the pendulum return force as a function of the body weight of a seat occupant, wherein the back part device has a molded part with a receptacle for the pendulum column, and a molded part receptacle, in which received the molded part is.
- the molding has one or more recesses and / or cavities, whereby it is elastically deformable, so that the pendulum column fastened in the molding can be moved back and forth. Depending on the body weight of the seat occupant, the molded part is deformed more or less axially.
- the elastically deformable molded part is therefore elastically deformable in a direction parallel to the pendulum column (axial), so that the pendulum column can dip into the molded part receptacle in this axial direction. It is further preferred that with increasing immersion depth of the chair leg in the mold receiving part, the molded part generates a higher restoring force in the lateral direction as soon as the chair leg is laterally deflected during a pendulum motion.
- the molded part is elastically movable back and forth in a direction lateral to the axial alignment of the pendulum column. It is further preferred if the molded part side wall of the molded part is circumferentially laterally supported against the supporting walls of the molded part receptacle such that the supporting walls form an abutment for the molded part as soon as the pendulum column reciprocates.
- the molding is positively against his form part side wall against the inside of the support walls, whereby a stable and secure fit between the molding and the molding receiving is achieved.
- a plurality of column-shaped recesses are formed in the molded part and extend up to the upper side of the molded part.
- a plurality of tubular recesses may be formed in the molded part, which extend to the top thereof. Insofar as the recesses or gaps or slots extend to the top, the trapped air is automatically vented when the molded part is deformed.
- a plurality of columnar or tubular recesses may be formed transversely in the molding and extend to the molding side wall.
- a cavity is formed between the underside of the molded part and the bottom of the molded part receptacle, wherein a vent opening is preferably provided in the bottom.
- molded part recording can also be one or more individually adjustable Auslenkungsbegrenzonne be formed in order to adjust the degree of deformation of the molded part and thus the spring characteristic in the corresponding deflection direction individually.
- the shaped part receptacle of the rear part device expediently has an adjusting screw in order to be able to adjust the shaped part in its depth in the shaped part receptacle and thereby to be able to adjust the lateral restoring force. If the molded part is screwed in deeper, then a region of the molded part is clamped in the molded part receptacle between the side walls, whereby the spring characteristic is changed so that an increased restoring force is generated with otherwise the same pendulum deflection.
- the molded part receptacle of the rear part device further comprises a spring which can be adjusted by means of a set screw and on which the molded part rests.
- the spring can be individually biased, so that thereby the position of the molding in the mold receiving part and the desired immersion depth can be adjusted at a certain body weight.
- a pendulum chair with a laterally deflectable pendulum column and a seat mounted on the pendulum column and a foot part wherein the remindstellvor- direction is arranged on the foot and the pendulum column is connected to the return device so that the corresponding spring characteristic and restoring force depends automatically adjusts the body weight of the seat occupant.
- the particular embodiment of the illustrated rear part of the device is not reserved for a particular seating, but it can on any seating such. a chair with gas spring can be used.

- Fig. 12 shows another embodiment of a rear part device with an eccentric bearing of the pendulum column.
- Fig. Shows a pendulum chair 2 with a seat 4 which is fixed to the upper end of a pendulum column 3.
- the pendulum column 3, which is also referred to below as a chair leg 3, is mounted in a lateral direction L ', L "movable back and forth on the foot part 5 by means of a rear part device 1.
- the arrows L', L" indicate the curved movement in FIG Lateral direction L, which the seat 4 executes during pendulum movements of the pendulum column 3.
- the directional arrow H indicates the height direction, which corresponds to the axial orientation A of the pendulum column in the idle state.
- the directional arrow L is orthogonal to the height direction H and indicates the horizontal component of the lateral movement.
- the seat 4 is shown with the pendulum column 3 in Fig. 1 once in the rest position and once in a deflected by the deflection AL position. In this position, a lateral restoring force arises in the rear part device 1, which depends on the direction-dependent spring characteristic (elastic modulus) of the restoring device 1.
- the return device 1 has a molded part 10, which in the present example is formed from an incompressible elastomer.
- the molded part 10 is formed in a funnel-shaped molded part receptacle 20 and is supported by its molding side wall 11 against the side wall of the molding receiving 20 from which is hereinafter referred to as a support wall 21.
- the funnel-shaped receptacle forms a solid support in the height direction H for the molded part 20.
- the end of the pendulum column 3 is fixed in the recess 2 and completely enveloped by the molding material.
- Between the bottom 14 of the molded part 0 and the bottom 22 of the molded part receptacle 20 is a cavity 15 '.
- the lower pendulum pivot 8 is located in the left view of FIG. 1 in a height H1. This view shows the rear part device 1 in its unloaded position. If, as shown in the right-hand view of FIG. 2, a weight force F of a seat occupant is introduced into the molded part 10 via the chair leg 3, the pendulum pivot 8 enters the molded part housing 20 in the height direction H by the amount .DELTA. ⁇ . This amount ⁇ is referred to as the penetration depth E. It can also be seen in the right-hand view of FIG.
- the pendulum fulcrum 8 moves in height direction down. There is then only a reduced mobility of the pendulum column (3) in the lateral direction L. If the pendulum column 3 in the left and the right representation by the deflection width AL, as shown in Fig. 1, laterally deflected, so turns a corresponding higher restoring force in the loaded case compared to the left-hand unloaded position.
- vent opening 23 At the bottom 22 of the molded part receptacle 20 there is a vent opening 23, so that the air in the cavity 15 'can escape during deformation of the molded part 10.
- 2 shows an alternative embodiment of the recesses 15 in the form of tubular recesses shown. Due to the special choice of the shape of the recesses 15 and the cavity 15 ', the bending stiffness and spring characteristic of the molded part 10 can be adjusted specifically. The spring characteristic is thus determined by both the shape and number of recesses and cavities and the appropriate choice of material of the molding material.
- FIG. 3 further alternative embodiments for the formation of the molding 10 are shown.
- a molded part 10 with 6 slot-shaped recesses 15 is shown. These extend from the chair leg end radially outward to the molding side wall 11.
- each 4 tubular recesses 15 are formed in the mold part 10.
- a further embodiment of a rear part device with transverse recesses 15 is shown.

- FIGS. 5 and 6 further embodiment of a rear part device 1 are shown, in which the molded part 10 has an hourglass-like shape and is constricted in the middle, resulting in a particularly good fit of the molded part 10 in the molded part receptacle 20 results. Furthermore, a schematic representation of the operation of these embodiments is explained. It can be seen that in the loaded state, which is shown in the right-hand views of FIGS. 5 and 6, the movement space for pendulum movements is limited as soon as the pendulum fulcrum 8 has been immersed in the molded part receptacle 20 by the penetration depth E. Also, the distance remaining to the support wall 21 has decreased from the value X1 to the value X2. As a result, a higher flexural rigidity will automatically set when loaded by the seat occupant.
- Fig. 7 further embodiments of a height-adjustable return device 1 with a screw 24 are shown.
- this case lets Set the recesses having molding 10 by means of a screw 24 in the height in the molding receiving 20.
- the desired bending stiffness of the molding 10 can be adjusted to the desired level. If, for example, the molded part is completely screwed into the molded part receptacle, the effective spring arm length of the pendulum column 3 is shortened and the molded part 20 can not be so severely deformed either.
- the molded part 10 can be tensioned against the funnel-shaped support wall 21, for example under appropriate tension, whereby the basic setting of the bending stiffness of the molded part 10 increases.
- the mode of action of the molded part 10 under the weight of a body weight follows the principles described above.
- Fig. 8 is a development of Fig. 7, in which the position also by means of a screw 24 is changed, wherein the molded part 10 here on a spring 25 and depending on the body weight of the seat occupant and the bias of the spring 25 to a desired level in the molded part receptacle 20 can dip.
- the effect associated with the invention can be optimized since, by combining the molded part 10 provided with the previously described recesses with the spring 25, the overall spring characteristic of the rear part 1 can be adjusted particularly well both in the axial and in the lateral direction.
- FIG. 9 shows an exemplary embodiment of a rear part device 1 with deflection limits in order to be able to set the spring characteristic of the rear part device 1 differently in different pendulum directions. It is desirable in some applications to achieve different strong restoring forces depending on the pendulum direction. So it is advantageous if pendulum movements generate a higher restoring force to the rear and thus a higher security for the seat user is guaranteed.
- deflection limits 30 can be provided.
- 5 segments are formed circumferentially on the molded part receptacle 20, which can be clamped differently against the foot part 5.
- clamping screws 26 can be used, which are mounted in corresponding recesses on the foot part 5 and can be rotated by means of a suitable rotary tool in the desired position.
- the desired spring characteristic of the restoring device 1 can be set in segments (depending on the set voltage).
- Fig. 10 discloses a further possibility to adjust the basic setting of the spring characteristic regardless of the automatic setting (by the molding 10) of the return device 1 can.
- the molded part 0 shown here is introduced into a molded part receptacle 20, which has a large number of spring tongues 27 around it.
- the spring tongues are clamped by a hose clamp 28 attached to the outer circumference.
- the hose clamp can be constricted by means of an eccentric screw 29 in diameter, whereby the molding material is deformed into the recesses 15 and the flexural rigidity is increased.
- the spring characteristic of the return device is adjustable.
- a return device 1 with a molded part 10 in which a molded part 10 'is introduced with a courtesy hardness than the molded part 10.
- the molding 10 'used here is arranged as a crescent-shaped part in the region of the molding 10 in which the deflection is to be more restricted (for example in the direction of a backrest).
- the molding 10 ' may be received in the molding 10 by overmolding or mechanical insertion. In this way one obtains an asymmetric spring characteristic.
- FIG. 12 shows, in which an eccentric bearing of the pendulum column is provided.
- This design of the molded part 10, in which the recess 12 for receiving the pendulum column 3 is arranged eccentrically or at least outside a symmetry center of the molded part 10, also has the effect that the molded part 10 thus formed has an asymmetric spring characteristic.
- molded parts 10, 10 'with a round, oval and / or crescent-shaped cross section alternative shapes may also be used, provided that they are designed so that the effect described above is achieved.
- the invention is not limited in its execution to the above-mentioned preferred embodiments.
- the reset device may be formed so that the molding can be adjusted in height by means of a set screw in the mold receiving part and / or that the molded part is mounted on a spring in the molded part receiving in height movable , It is also conceivable that one or more individually adjustable Auslenkungsbegrenzungen (are formed in order to adjust the degree of deformation of the molded part and thus the restoring force in the corresponding deflection direction in the molded part.
