Definitions

  • the invention relates to a bar stool according to the generic term of claim 1, cf. WO-A-96 24273.
  • Bar stools that cannot be tilted or reset are generally known. They have the disadvantage that you sit on them very static. The back muscles of the users relax on long evenings which leads to an unfavorable sitting position. A large part of the population practices in the office during the day a sedentary activity, which also leads to degeneration the back muscles contribute. Sitting in particular such people with already weakened back muscles even in the evening on static bar stools, this usually leads to an unfavorable sitting posture and resulting Backache. Through a persistent, even load of the intervertebral discs these become extremely bad is supplied with blood, which results in permanent back damage can.
  • the object of the invention is therefore a bar stool to improve in that this a healthy sitting allows.
  • the object is achieved by that the foot part has a fixed Has shaft arranged on the shaft a foot ring is.
  • the hinge point between the foot part and the intermediate part lies at the upper end of the shaft.
  • the fixed shaft ensures that the Hinge point not too far from the seat and thus the pendulum movement is limited to a favorable extent is.
  • the pendulum point were on the ground, it would be with a bar stool the commute is too long and a safe one Use by unfamiliar people is no longer possible.
  • the foot ring in height is adjustable so that an optimal adjustment to the user can be made.
  • the user can thus put his feet on the Turn off the foot ring and have a swinging buttocks and Upper body a secure, steady hold by putting it on his feet on the ring.
  • a preferred embodiment provides that the resilient Intermediate part from a central pillar and one Spring construction is in the power flow of the seat weight the central pillar and the spring construction in Series are connected.
  • the central one Column adjustable height can be formed without the suspension around the longitudinal axis is impaired.
  • the central pillar and the spring construction are arranged concentrically and between the central Pillar and the spring structure formed a bearing guide is. Due to the concentric arrangement of central Pillar and spring construction it is possible in one relatively compact arrangement of the series connection of central pillar and spring construction. This is therefore of great importance - as already above mentioned - the tipping point not too far from the seat may be distant and thus a mere string together the tipping point of the central column and spring construction would move too far towards the foot section.
  • the spring construction advantageously has a dynamic one and static spring support on between which a spring is clamped. Through this relatively simple It is possible to use a cheap standard part spring.
  • the central pillar is advantageously as one in it Length adjustable spring column, such as a gas spring and has at least one vertical guideway which interacts with the warehouse management.
  • the camp management conveniently includes one in height arranged two-part storage, being as bearing elements preferably balls or rollers are used.
  • the Bearing elements pressed spring-loaded against the guideway.
  • non-spring loaded Bearing elements are in the pendulum and swinging movement Manufacturing inaccuracies are noticeable and have an effect very disturbing when sitting actively and dynamically.
  • the bearing elements are advantageously in Bearing element receptacles held, the bearing element receptacles either via compression springs, or via an elastic deformable area, or over an elastic deformable projection the bearing elements on the guideway to press.
  • the compression springs or the elastically deformable The area or the projections press the bearing elements radially inwards.
  • the guideway is advantageously designed as a tube, its first end with the lower end of the spring column and its second end with the dynamic end of the spring holder connected is.
  • the guideway tube and the spring column which is preferably a gas spring is designed to arrange a plain bearing bush.
  • a gas spring is designed to arrange a plain bearing bush.
  • the bearing guide is preferably on a main body arranged in which the inventory are spring loaded and held radially displaceable. Due to the spring-loaded bearing elements, dimensional inaccuracies balanced and there is thus a even, trouble-free and almost silent swinging about the longitudinal axis of the intermediate part.
  • the main leg body is preferably over a Wedge connection attachable to the shaft on the foot section.
  • the distance between the dynamic and the static spring mount can be adjusted.
  • a rotatable union nut on the main leg base formed as a spring support over which can bias the spring.
  • This biasing mechanism is advantageously via a rotatable union nut formed on the main leg body, over which the spring is biased by turning the union nut or can be relaxed.
  • the reset device is conveniently a vibrating metal formed between the intermediate part and the foot part and can be set via a handwheel in the restoring force become.
