Abstract
Lifting mechanism for rotating seats chairs and similar chairs characterized essentially by the fact of behaving a set of legs attached and attached to a tube which is open by its upper base and closed by the bottom of which starts inside and centrally a thread threaded bar thyme that rises to the level that determines the mouth of said tube by plugging into it telescopically another upper tube attached to the seat and opened by the center of its lower base to give way to the mentioned thyme existing inside this second tube a fixed piece and fitted to it which is emptied axially to allow free passage of the threaded rod whose part has a base underneath a recess in which a distension spring disposed around the threaded bar and supported on a coaxial bearing that in turn is mounted on a part that acts as a nut of the threaded rod and that presents in its lower base and directed s upwards two blind holes destined to receive two lugs located on the internal face of the lower base of the upper tube plugged in, the assembly being established so that when a person sits in the seat the height of the same remains invariable thanks to the pressure that exerts that is transmitted through the upper tube plugged into the part internally adjusted to that which compresses the spring to the limit that determines the maximum compression of the same forcing the inner lugs arranged at the base of it to come out of the blind holes of the nut-piece remaining fixed on a point of the threaded rod thus maintaining constant the height of the seat before any rotation of the seat effected by the existing coaxial bearing in the nut piece in order to vary the height of the seat until rotating this one in one way or another depending on whether you want to raise or lower it, because when the person withdraws from it, the pressure on the upper tube plugged in and thanks to the distension of the spring the lugs are inserted in their corresponding holes of the nut piece which is dragged by them when turning the attached upper tube jointly and therefore to the seat thus moving the part-nut along the threaded bar with which the height of the seat is varied.
