Definitions

  • the present Invention provides a furniture unit to sit on it; it is designed for application when resting or performing office work.
  • the solution cited comprises a rocking chair equipped with a seat with a lower convex part forming a spherical surface with its central point set above the seat.
  • the rotating rollers contacting the lower convex surface allow for the convex part to move along the spherical surface and the chair supporting part.
  • the hitherto used furniture units designed for sitting on allow that the following movements of the sitting person's body are possible: leaning, vibrations, rocking or driving, but the individual body parts move toward each other only accidentally.
  • the objective of the Invention is, on the one hand, to ensure, while sitting, the stabilization of specific body axes.
  • the objective is to concurrently ensure a motion around those axes in order to enable the controlled rotational movements of torso since they determine the frequent and easy changing of the workload of articular surfaces and capsules, ligaments, and muscles.
  • the furniture unit to sit-on comprises a main frame, a seat, and a backrest frame.
  • the seat is mounted either to the main frame or to the adjustable base of the backrest frame equipped with at least one backrest.
  • the furniture unit to sit-on is characterized by a feature consisting in that a bearing of the ball joint is fixed to the seat, and the ball of the ball joint is mounted to the main frame or to the base of the backrest frame, whereas the diameter of ball joint is smaller than 15 cm.
  • the backrest frame is equipped with three independent movable rest elements; the middle rest element may be embedded in the frame using a ball joint, and, additionally, both the upper and the lower rests can be made of two independent elements placed parallel toward each other and symmetrically, towards the vertical axis, to the backrest frame.
  • one embodiment variant of the furniture unit to sit-on is equipped with a footrest with two movable props for feet; the props are pivotally connected with the frame of the footrest using a crank assembly.
  • an element may be fixed and serve as a rest for raised upper extremities.
  • the furniture unit may be also equipped with an armrest mounted to the base of the backrest frame.
  • an armrest mounted to the base of the backrest frame.
  • a work surface or a top for a monitor can be fixed, or those two elements.
  • a small diameter of the ball joint guarantees that the body rotation axis agrees with or is close to agree with the spinal column axis, therefore, the destructive transverse forces are eliminated.
  • the inter-segmental mobility of spinal column is guaranteed by the stability of specific axes of the sitting person's body (spinal column axis, lateral axis at the head base, and lateral axis of pelvis), and by the possible motion of the body around those axes; the Invention simultaneously ensures both the necessary stability and the motion potential.
  • the sitting and working person can comfortably rest and it a rigid, unchangeable position of his back during a longer period of time.
  • footrest with movable props for the feet makes it possible that the lower extremities work continuously while the person sits, and, thus, the muscle pump of lower extremities is activated; this prevents varices.
  • FIG. 1 there is a diagrammatic drawing of a side-view of the furniture unit to sit-on
  • FIG. 2 there is a diagrammatic drawing of the furniture unit without its seat.
  • the furniture unit to sit-on has a main frame 2 connected by a joint with the frame base of the backrest 3 .
  • a seat 1 is placed; it is fixed to the main frame 2 or, alternatively, to the frame base of the backrest 3 by a ball joint A.
  • the said connection is made so that a bearing A 1 of the ball joint A is mounted to the seat 1 , and the ball A 2 of the ball joint A is fixed onto the main base 2 or, alternatively, onto the frame base of the backrest 3 .
  • the frame base of the backrest 3 has armrests 11 mounted to an adjustable jib, as well as a working surface or a top 12 for a computer keyboard, mounted onto an another jig 13 .
  • An arm for securing a top for LCD monitor or PC screen is mounted to the jib 13 that fixes a working surface or a top 12 for keyboard.
  • the backrest frame 4 has a durable connection with the frame base of the backrest 3 and those two elements have jointly a possibility to adjust the up or down position and/or the inclination angle.
  • the backrest frame 4 is equipped with three (3) independent movable rests: an upper headrest 5 , a middle chestrest 6 , and a lower backrest 7 .
  • the middle chestrest 6 is secured to the backrest frame 4 using a ball joint C whereas the upper rest 5 and the lower rest 7 are connected with the backrest frame 4 in a way that makes it possible to slightly (within a short distance range) move them forwards and backwards, or up and down, or aside.
  • the rest elements 5 and 7 may be coupled with the backrest frame 4 using a spring-loaded telescopic mechanism.
  • a rest element 10 for lower extremities is placed on a jib.
  • a footrest 8 is secured; it has two movable props for feet, which are connected by a flexible joint with the footrest frame using a crank assembly 9 .
  • the foot props can move up and down, as well as rotate.
  • the footrest 8 is secured so that it can be freely pulled out and placed in a position allowing to place his/her feet thereon or it can be placed under the main frame 2 when not used.
  • the footrest 8 can be situated using, for example, a rail, or it can have a telescopic connection. The latter makes it possible to adjust the distance between the footrest and the main frame 2 .
