Definitions

  • the invention relates one joint (or: seat part storage) for one-sided elastically inclinable seat part of a seat device.
  • a seat part With seating, it makes ergonomic sense to have a seat part to provide that with an elastic restoring force is tilted on all sides, so that active-dynamic Sitting is guaranteed.
  • Such a seat part makes it possible the seated person, when tilted from the upright sitting position back to the starting position with relatively little body work return to.
  • the invention has the particular advantage that through it a real seat device compared to the "Pezzi” gymnastic ball, the at least as good, if not even better physiological properties like the "Pezzi-Ball" having.
  • a seat device in which a joint according to the present invention can be provided, like a gymnastics ball, has a curved support surface on. This is at least in one area a support point on the support surface is spherical shaped.
  • the seat device is provided with a seat part, that is stored in a support point.
  • the support point is either below the center of curvature of the base area or is within a height range adjustable, the lower limit below the Center of curvature lies and its upper limit below of the center of curvature or substantially coincides with this.
  • the seated is thus Always in a stable equilibrium position, even with larger tilt angles. Basically, when sitting on a ball an unstable equilibrium. Just by the change in shape (flattening) of the air-filled ball the seat and the support surface is in use and with small tilt angles a quasi-indifferent balance generated.
  • the seat part is tilted in the support point, an upright sitting position around the seated person at every angle to enable.
  • This can e.g. by one at that Connection element attached to the seat part, e.g. a rubber sheet, be made possible by a suitable support is supported, whereby the seat part on all sides is inclinable.
  • the seat part in addition be cushioned in the vertical direction.
  • the seat device 10 shown schematically in FIG. 1 contains a foot part 1, which has a curved bearing surface 1A has, so that the seat device 10 in balance a support point 1B of the support surface 1A on a flat Pad rests and can be tilted.
  • the seat device 10 also has a seat part 2, which by a column part 3 is supported in a point 3A.
  • the seat part 2 can spring in the vertical direction.
  • a seat device "Pezzi-Ball" used these elements are all in one piece connected to each other, with the seat surface of the support surface is spaced by the diameter of the ball.
  • the seat device can be designed so that the support point at a constant height H below the center of curvature the contact surface is located. But it can also as provided in Fig. 1, e.g. in the column part 3 a Height adjustment 3B, e.g. in the form of a gas pressure spring, be arranged through which the support point 3A and so that the seat part 2 is adjustable in a height range.
  • This height range has a lower limit, the in any case lies below the center of curvature.
  • the upper limit can either be below the center of curvature lie or essentially coincide with this.
  • the height of the support point can be adjusted, for example by a gas pressure spring or a screw thread be realized or by a discontinuous Locking, in which tubes can be slid into each other and at certain relative positions through pins and holes can be locked (such as with crutches).
  • the seat can be tilted on all sides arranged so that they do not with lateral deflections becomes lopsided and thereby forces on the spine and Holding apparatus are exercised and in particular none below health-related undesirable curvature of the spine with corresponding incorrect loading becomes.
  • the inclination of the seat also allows the physiologically desired tilting of the pelvis forward (as with the "knee chair") also in the zero position. After all, it prevents the all-inclinable and therefore Horizontal seat that one can look at from the side Deflection of the chair constantly by footwork against one Slip off an oblique seat.
  • the suspension can be in their elasticity can be adjusted to suit them individual requirements - such as body weight.
  • an elastic spring can also a rigid connecting element, e.g. a rigid rod, be provided.
  • the vertical suspension can then e.g. by an elastic foot part can be provided.
  • the seat device 1 is a practical embodiment of the seat device 1 and a possible type of edition shown schematically on support point 3A (but without delimiter). It reference numerals were chosen in a corresponding manner.
  • the column part 3 is with a calotte 5, in the highest point 3A the Seat part is supported.
  • the seat part 2 has one its lower area attached hard rubber plate 4, which in the support point 3A of the calotte 5 on all sides is tilted.
  • the hard rubber plate 4 takes over thus the function of a vertical suspension of the seat part.
  • Fig. 3 also shows the limiter in the form of a hard rubber washer 6, below the hard rubber plate 4 is arranged in a ring around the column part 3, around which in Use of the hard rubber plate loaded from above 4 to provide a resilient resistance from below.
  • This second suspension can vary depending on individual requirements - e.g. Body weight - can be adjusted, e.g. thereby that it is adjustable in height on the column part 3, as in the Fig. 2 is indicated schematically by the screw thread.
  • the column part 3 is moved by the tilt angle inclined and inclined at the same angle in reverse Direction the hard rubber plate 4 with the seat part 2 around the support point 3A of the calotte 5. In the result remains So the seat part 2 due to its opposite tilt relative position in relation to support point 3A.
  • the elasticity of the hard rubber plate 4 ensures that vertical suspension of the seat device.
  • the setting of the Seat height can be relatively simple by varying the thickness of the Hard rubber plate 4 take place.
  • FIG. 1 shows one Support surface 1A, in its entirety as a spherical surface is trained. Instead, one can Support surface can be provided, which is only in a central Partial area around the equilibrium support point 1B is formed, but outside of this range one of the spherical surface has a different shape. This can be done in can be used advantageously to the Secure the seat device against tipping over.
  • a radially outer area is to this Purpose shaped in such a way that at large angles of tilt a restoring moment is generated, for example by in this area the radius of curvature steadily outwards increases, e.g. like a parabola or hyperbola.
  • a appropriately designed tilt-proof design is especially for children or Disabled beneficial.
  • the seat 2 have a convex shape, for unrestricted freedom of movement, especially for the To ensure thighs and thus the whole To activate leg muscles when sitting.
  • the support point 3A eccentrically so far back on the seat part that when sitting tipping the pelvis forward is forced.
  • the inclination of the seat part 2 by the support in the Support point 3A can also be used as an elastic joint suspension be carried out with a restoring force. In this Fall becomes out of equilibrium without restoring force an overall stable balance.
  • Column and foot part can also be used as a single, design Unit, such as a cone or Cylinder with (at least partially) spherical base. Otherwise, the construction leaves designs in all Materials, i.e. in plastic, metal or wood or their Combinations too. This has the further advantage of being significant higher resistance to destruction than the known air-filled gymnastics balls made of plastic like that "Pezzi Ball". As with the Pezzi Ball, it can also be used for the footrest is elastic be carried out, for example in the form of an inflatable, air-filled hollow body, which has an elastic membrane.
  • the seat device shown is good physiological properties also as work or office chair usable. It is particularly adjustable due to its height can be used universally for all body sizes. Thanks to its safety against tipping, the application is ideal Children or disabled.
  • a seat device contains a support part 11, a curved bearing surface 11A at its upper end has, so for example as a dome with a central flattened spherical surface is formed.
  • a seat part is in its lower area with a plate 12A made of rubber or another elastic material that is firmly connected in contains a through hole in a central area.
  • the Through hole is ring-shaped through the inside Metal or plastic reinforcement 12B formed in cross section Is U-shaped. Instead of a U-shape, one could L-shape or a simple socket can be selected.
  • the reinforcement is firmly connected to the elastic plate.
  • the through hole serves the defined fastening of the elastic plate to the support part by a screw 12C.
  • the screw 12C can through a through hole in the top surface of the support part inserted and on the inside of the top surface with a Screw nut are attached. The attachment can naturally also take place in another suitable way.
  • a ring-shaped, rubber-reinforced limiter 13 attached around the support part. This consists of an annular carrier 13A and one therein formed recess for receiving a ring 13B made of rubber or another elastic material.
  • adjusting ring around the support part 14 attached, which in the preferred embodiment with the Support part is in screw connection and accordingly has a thread on its inside, which in a corresponding Thread engages on the outside of the support part.
  • the limiter supported by the collar is thus height adjustable by turning the adjusting ring.
  • the limiter is cylindrically symmetrical to the axis of the support part is shaped, it can be inexpensive also be made in one piece with the adjusting ring.
  • the limiter and the collar separate components, so that the limiter does not turn when the height is adjusted and therefore also non-cylindrical symmetry to the axis can be shaped.
  • This can be done in an advantageous manner be used in different directions of the seat device a different elasticity and limitation of deflection to be provided in case of tilting.
  • the elastic Ring varies in shape and thickness along its circumference executed, e.g. back higher than front to to achieve a greater elastic limitation at the rear than at the front. It can also run along a certain circumferential section be wedge-shaped. It can also be longitudinal oval and be positioned eccentrically to the center of the column part.
