Definitions

  • the invention relates to a chair with a stand-up position, and in particular to a chair comprising a support, a seat, a back support and a foot rest, which by means of a first hinge is connected to the seat via a, in use horizontally orientated, hinge axis wherein the foot rest by means of a second hinge is connected to the support via a, in use horizontally orientated, hinge axis and wherein the foot rest is connected with an actuator for the hinging movement of the foot rest around the second hinge axis.
  • Such chairs are known.
  • An example of such a chair is the Doge-Modulair, available from Doge Collection at Oisterwijk, the Netherlands.
  • the known chairs have the drawback that the mechanism for obtaining the various positions of the chair is rather complex and consequently costly. For example to adjust the position, three actuators are needed and three electromotors. In addition, a complicated guide system is required to enable the chair's seat, back support and foot rest to move synchronously. Moreover, the stand-up position of the existing chairs is realised by merely tilting in the first instance the seat, and usually also the back support and the foot rest. This movement, however, insufficiently follows the movement made by the human body when rising, and therefore affords insufficient support for this movement. For a better support, the seat should not only tilt, but should simultaneously also lift and move forward.
  • the first hinge locks in a particular position, for example, when the foot rest and the seat are approximately at right angles to each other, so that a further tilting of the foot rest in the direction under the seat causes the seat to be tilted upward into a stand-up position.
  • the hinge axis of the second hinge will be located in front of the front side of the seat. If, in any case from this position, the first hinge locks and the actuator subsequently move the foot rest to the stand-up position, then the seat will not only tilt but will simultaneously lift as a unit, and thus follow the natural movement of the rising human body.
  • the actuator is a linear actuator that engages the foot rest below the second hinge. The actuator then rests on the support. By moving the point of application of the actuator further away from the second hinge, a more favourable torque for the movement into the stand-up position is obtained.
  • the actuator can be adjusted to a number of predetermined positions, with the positions comprising at least a sitting position wherein the seat is substantially horizontal, and a stand-up position wherein the seat extends upwards from the first hinge at a predetermined angle, and a relax position wherein the foot rest is substantially horizontal, and the seat extends downwards from the first hinge at a predetermined angle.
  • the chair according to the invention is adjustable to any position between the relax position, the sitting position and the stand-up position.
  • the chair according to the invention such that the foot rest, the seat and the back support, or at least one of these three, comprises a tubular frame, composed of a telescopic tube for adjusting one or several dimensions, a construction is obtained whose dimensions may be very readily adapted to the current wishes.
  • Figs. 1-5 show cross-sectional side-views of a chair 1 according to the present invention, comprising a seat 2, a back support 3 and a foot rest having a straight portion 4 and a curved portion 5.
  • the seat 2 is connected with the foot rest 4, 5 by means of a first hinge 7.
  • Hinge 7 has a horizontal hinge axis and is provided with a locking device, which is not shown. This locking device stops the hinging action of the hinge 7 from a particular angle, as will be further explained below.
  • the locking device may be formed, for example, by a stop pin or any other suitable means in accordance with the art.
  • the chair 1 is further provided with a support 6, of which the schematic illustrations in Figs. 1-4 only show two components.
  • the foot rest 4, 5 is connected with the support 6 by means of a second hinge 8.
  • the actuator 9 is a linear actuator in the form of a ball circulating screw, driven by an electromotor. It is also possible to use other suitable actuators.
  • At the lower side of the seat 2 there is further provided a wheel which, when the chair 1 is in certain positions, rotatingly rests on a guide strip that is part of the support 6.
  • Fig. 1 shows the chair in the relax position. In this position the actuator 9 is in its most extended, screwed out position and the straight portion 4 of the foot rest 4, 5 is substantially horizontal.
  • the seat 2 extends from the foot rest 4, 5 towards the back support 3 downward, and the seat 2 rests via the wheel 10 on the guide rail of the support 6.
  • Fig. 5 further shows that when moving the chair 1 from the sitting position shown in Fig. 3 to the stand-up position shown in Fig. 4, the seat is not only tilted but also lifted.
  • Fig. 5 shows an enlarged detail of the foot rest 4, 5 and the seat 2, in the same position as shown in Fig. 3.
  • a broken arc line represents the path travelled by the first hinge 7 and thus the starting position of seat 2 when the chair is moved from the sitting position of Fig. 3 into the stand-up position of Fig. 4.
  • Fig. 5 then clearly shows that in addition to a tilting movement, the seat in its entirety also makes an upward and forward movement over the distance h indicated in Fig. 5.
  • This chair 1 embodying the invention provides a stand-up chair that follows the rising movement natural to the human anatomy in an excellent manner, while this chair is realised using only one actuator and remarkably few extra components. It will be understood that apart from the described embodiment numerous changes may be made without departing from the scope of the present invention as described in the appended claims.
