Definitions

  • the invention relates to a seat piece of furniture with a base and a seat unit, wherein between the base and the seat unit a rotary bearing comprising a base-side bearing means and a seating unit side bearing means is provided by means of which the seat unit is rotatable about a vertical axis relative to the base.
  • the rotary bearing on a switchable blocking device, by means of which the rotational mobility of the storage facilities is mutually blocked.
  • the invention also relates to a fitting for such a piece of seating furniture.
  • Generic seating furniture pieces are known from the prior art. These are seat furniture pieces whose seat unit is basically rotatable relative to a base, wherein the base can be both a foot provided for stationary installation and a base portion provided with rollers. The latter is well known in particular office seating furniture.
  • the rotational mobility of the seat unit allows the seated person to rotate the seat unit without twisting the base, thus assuming a seated position with a changed orientation.
  • the pivot bearing which is provided for this purpose between the base and the seat unit, is provided in the case of generic seating furniture pieces with a blocking device that the base and the seat unit in a given relative rotational position coupled to each other so that a rotational movement is no longer possible or strong is difficult.
  • the aforementioned blockability is particularly useful if it is a piece of seating furniture with a stand-up.
  • a stand-up aid makes it possible to raise the seat unit in particular by an electric motor, so that getting up from the piece of seating furniture is facilitated.
  • In the phase of getting up is one Rotary movement of the seat unit generally not desired.
  • the blocking prevents when rising, that it comes to falls due to the rotational movement of the seat unit.
  • a seat piece of furniture according to the preamble of claim 1 and a fitting according to the preamble of claim 11 is for example made GB 2 430 009 A known.
  • the object of the invention is therefore to develop a generic piece of seating furniture or a fitting for such a piece of seating furniture to the effect that the switchable blocking device is inexpensive and reliable.
  • the object is achieved in that the blocking device has a blocking surface, a torsion spring surrounding this blocking surface and a switching device.
  • Said blocking surface is provided on a first of the two storage facilities.
  • the said torsion spring wraps around this blocking surface and is fastened to a second bearing device and is such that it can be varied depending on the state of stress Inner diameter has.
  • the switching device is coupled to the torsion spring in such a way that the torsion spring can either tension or relax.
  • the torsion spring and the blocking surface are matched to one another such that the torsion spring rests against the blocking surface either in the clamped, compressed or relaxed contracted state, thereby preventing a rotational movement between the bearing devices.
  • the inventive design of the blocking device thus provides that it has a circumferential blocking surface on which said torsion spring can create a clamping and from which the torsion spring, the blocking surface can be lifted releasing.
  • the blocking surface is a preferably cylindrical surface which is aligned in the direction of the vertical axis.
  • the torsion spring surrounds this blocking surface one or more times. It is of such a nature that, in a tightly strained or relaxed state, it bears in a clamped manner on the blocking surface and thus can not be moved relative to it, and in contrast other other more relaxed or stressed state exerts no or less force on the blocking surface and therefore permits the rotational movement.
  • the switching device can basically be an electrically operated switching device, which expands or contracts the torsion spring.
  • the switching device is a mechanical component that provides mechanical coupling with other subcomponents of the seating furniture piece and thus establishes the released and the blocked state of the blocking device in response to the movement of these other parts.
  • the torsion spring used is such that its inner diameter depends on its state of tension. This is achieved in particular by a torsion spring with in particular helically arranged turns.
  • the cross section through these turns can be circular.
  • a square or otherwise rectangular shape may be advantageous, since such a shape causes a facilitated rotationally secured clamping and allows surface contact between the inside of the turns and the blocking surface.
  • the end of the windings is preferably formed by two torque introduction sections whose relative position in the circumferential direction determines the state of stress.
  • the ends of these turns can be directed radially or obliquely outwards, as is usual with leg springs.
  • leg springs are advantageous in view of the low cost of the blocking device.
  • the one or more torsion springs together loop around the blocking surface over an angle of at least about 360 ° ( ⁇ 15%).
  • the blocking surface is thus clamped at least almost circumferentially by the torsion spring or the torsion springs.
  • Particularly advantageous embodiments are considered in which the torsion spring or the plurality of torsion springs wrap around the blocking surface over an angle of approximately 1080 ° ( ⁇ 15%) or 1800 ° ( ⁇ 15%). It is therefore Bacumschlingungswinkel that provide that the blocking surface is looped about three times or about five times.
  • the tension in the torsion spring provided for producing or releasing the blocking state also leads to a torque acting in the circumferential direction, which is not desired. It is therefore of advantage if an even number of torsion springs, in particular two torsion springs, are used, which are tensioned or relaxed relative to the circumferential direction during simultaneous tensioning or simultaneous expansion in opposite directions so that their torque acting in the circumferential direction is compensated in each case becomes.
  • these two torsion springs wrap around the blocking surface over an angle of approximately 540 ° ( ⁇ 15 °) or approximately 900 ° ( ⁇ 15 °), ie approximately one and a half times or two and a half times ,
  • the switching device preferably has a switching slide, which is axially movable along the first or second bearing device guided by a guide.
  • This shift carriage is operatively coupled to the torsion spring or the torsion springs such that the axial displacement of the shift carriage causes a tensioning or relaxing of the torsion spring and thus blocking or releasing the blocking device.
  • the storage of the shift carriage on the first or second bearing device can be formed in the simplest case by a slot with arranged therein slider, in particular in the form of screws.
  • the displacement of the shift carriage can in particular be effected indirectly by a displacement of other subcomponents of the piece of seating furniture. In principle, however, a direct electrical drive of the shift carriage is possible.
  • the interaction between the shift carriage on the one hand and the at least one torsion spring on the other hand preferably takes place in that at least one shift bevel is arranged directly on the shift carriage, by the axial displacement of which a torque introduction section of the torsion spring derived therefrom is displaced in the circumferential direction.
  • the shift carriage can also have two Heidelbergschrägen.
  • a shift carriage with two shift bevels is advantageous if more than one torsion spring is used, so that each one torque introduction section of a plurality of torsion springs is jointly deflected by the shift carriage. If the shift carriage has a plurality of shift bevels, these are preferably offset from one another in the axial direction, so that there is no need to position the torque introduction sections of the plurality of torsion springs at the same height.
  • shift carriage intermediate member which may be provided, for example, pivotally mounted on the second bearing means.
  • This intermediate member in turn acts on one or more torque introduction portions of the torsion spring or torsion springs, so that they are deflected in response to the displacement of the intermediate member in the circumferential direction.
  • the torque introduction section movable relative to the second bearing device is movably guided. This can be achieved for example by a slot through which leads the torque introduction section.
  • a guide is not absolutely necessary, since already the wrap-around shape of the spring usually ensures sufficient axial positional stability of the torque introduction sections.
  • a return spring is provided by means of which the shift carriage is permanently acted upon in the direction of its end position. It is particularly advantageous if this return spring is not formed as a separate spring element, but is formed by the one or more torsion springs.
  • this return spring is not formed as a separate spring element, but is formed by the one or more torsion springs.
  • this serves the purpose in a described manner to convert the axial movement of the shift carriage in a circumferential direction of one or more torque introduction sections.
  • the torque introduction sections can also exert the restoring force on the shift carriage by exerting an axial force on the shift carriage by virtue of the torque introduction sections acting in the circumferential direction by deflecting the shift ramp.
  • a further design of the switching device provides a shift lever, which is pivotally mounted on the first or the second bearing device is attached and which is operatively coupled to the torsion spring such that a pivoting movement of the shift lever causes a tensioning or relaxing the torsion spring and thus blocking or releasing the blocking device, wherein preferably the shift lever is connected to a torque introduction portion of the torsion spring, so that these by a pivoting movement of the shift lever is displaceable in the circumferential direction.
  • a shift lever is preferably provided per torsion spring.
  • the torsion or the torsion springs are preferably provided on the seat-side bearing means and each pivotable about a horizontal pivot axis.
  • an arm of the at least one shift lever is connected to a torque introduction portion of a torsion spring, so that it is moved in the circumferential direction when the shift lever pivots. The pivoting movement of the shift lever thus leads to the desired blocking or release.
  • the switching of the blocking device can be realized in various ways.
  • a particularly advantageous design provides that it is a piece of seating furniture with a stand-up function, through which the seat can be raised to facilitate getting up from the sitting position.
  • the blocking device can be operatively coupled with the stand-up assistance function in such a way that it assumes its blocked state upon actuation of the stand-up assistance function.
  • the stand-up can be designed by a motor in a conventional manner. In principle, however, a mechanical, for example spring-operated stand-up assistance function is also conceivable.
  • the coupling of the stand-up assistance function with the blocking device is particularly useful because a rotation of the seat counteracts the easier getting up.
  • the production of the blocked state upon activation of the stand-up is therefore expedient.
  • a control lever is provided for manual actuation, which is preferably also such that it is the axially displaceable shift carriage or the pivotable shift lever can move.
  • a control lever may be provided in the manner well known by office seating pieces of furniture below the seat and allow either a permanent blocking and releasing or allow a temporary release from a normally blocked state by displacement of the operating lever.
  • the distribution of the first and second bearing device on the base or the seat is basically arbitrary.
  • the blocking surface can therefore be either rotationally fixed to the seat or the base, while the torsion spring is stationary to the other storage device.
  • the blocking surface and the first bearing means are provided on the base side and the torsion spring and the second bearing means are provided on the seat side. This makes it possible to switch seat-side actuators such as the aforementioned operating lever or the stand-up assistance function in a facilitated manner with the torsion spring switching.
