Definitions

  • the present invention refers to an adjustment device for a tiltable armchair or a similar sitting furniture.
  • Disabled persons often have great difficulties to sit down and to get up from chair seats if they can't get assistance or support from another person. It is evident that this not always can be offered when the disabled person wishes to get up from a sitting position or to get seated from a standing position.
  • the object of the present invention is to offer an adjustment device by means of which a well functioning and easy adaptable accessory of this type is provided and the characteristics of the device are evident from claim 1.
  • the device shown in the figures includes a stand 1 in the shape of two tube frames 2, each in the form of a tube with the ends bent to eqally long double folded legs 3. These tube frames 2 are mutually connected by means of a horisontal front cross bar 4a and a rear cross bar hinted at 4b whereby the stand 1 constitutes an essentially horizontal, rectangular frame supported by four legs 2.
  • a horisontal front cross bar 4a and a rear cross bar hinted at 4b whereby the stand 1 constitutes an essentially horizontal, rectangular frame supported by four legs 2.
  • the front cross bar 4a are pivotally connected one end of each of two at a distance from each other arms 5, which, as is evident from Fig.
  • a transverse axis 11 is placed on a lower level, which axis centrally supports a pressure arm 12 pivotally hinged thereon, which pressure arm at its opposite end ends with a wheel 13 the axis of which is parallel to the transverse axis, and which in operative position bears against the underside of the seat board 9 and is arranged to adjust the seat board into different oblique positions under pressure.
  • the pressure arm 12 for this purpose is equipped with an attachment bracket 14 perpendicular to the pressure arm which bracket is attached to the piston rod 15 of an electric actuator 16, which is pivotally suspended at its opposite end in a support structure 17 in the shape of cooperative rods, which are fastened to the stand and go together at a low point of attachment near the center of the stand, where the actuator is pivotally connected.
  • the electric actuator 16 is naturally equipped with a power supply cable as well as cables (not shown in the figures) for controlling the actuator, which cables preferably are provided within an arm of the chair, in which the device shall be included, or to another appropriate position from an operational point of view.
  • a cantilever control bar 19 is pivotally connected, which bar extends in the longitudinal direction of the stand along the major part of the stand.
  • This control bar 19 is arranged to be turned during the movement of the rod piston 15 and the tilt of the pressure arm 12 caused thereof, but its rotational movement upwards is limited at the front by a horisontally extending axis 20, arranged between the arms 5, with a backing roller 21 provided on said axis, which by means of a locking screw is lockable in different eccentric positions onto the axis, whereby the front stop face of the control bar is settable.
  • control bar 19 At the rear the movement of the control bar 19 is limited upwards by the rear cross bar 4b provided in connection with the mentioned slide rail 10 for the end portions of the fork 7.
  • the control bar 19 is at its rear part furthermore equipped with a second arm portion 23, which is rotatably pivoted at point 22 on the control bar 19 and lockable in different tilting positions with respect to this point.
  • the movement path of the control bar can be adjusted after desiderata, to control the angle of elevation, to determine when the movement of the seatboard shall be transferred from a pure lifting movement to a combined lift-and tilting movement and even to adjust the sitting height of the chair, so that the height of the chair in a simple way can be adapted to different desiderata.
  • Fig. 1 is shown a lateral view of the chair stand 1 in its sitting position, ie. the seat board 9 is in a horisontal, and even in a back leaned position.
  • the front part of the chair stand in the figure is turned to the right while the side that supports the back is the left side in the figures. In this position the piston rod 15 of the actuator is maximally withdrawn.
  • the backing roller 21 can be turned eccentric about its horisontal axis 20 and be locked in an optional position by means of its adjusting screw, and partly the other arm portion 23 of the control bar can be biased upwards in respect with the control bar 19 and likewise be locked in the desired position with its locking screw.
  • the front part of the control bar comes in contact with the backing roller 21 and thereby begins to exert a lifting force onto the fork 7 and thereby associated parts and when the rear part of the control bars comes to bear against the rear cross bar 4b and thereby interrupts the lifting movement of the seat board.
  • the actuator 16 can of course be stopped in each desired position of motion, whereby one even through this function can adapt the height of lift and the tilt motion exactly after individual desiderata, and the movable parts can thus thereby be continuously stopped anywhere in its movement path.
  • a chair that constitutes a well functioning accessory for persons, who have difficulties to sit down in a chair or armchair and who have difficulties to get up from the same, and which furthermore is easy adjustable to adapt the movement pattern and the sitting height of the seat board after individual height and bodily constitution of each person.
