Definitions

  • the invention relates to a device for lifting a person from a sitting position to an at least almost upright position.
  • the device comprises a seat with a seat surface and at least one lifting device coupled to the seat for vertical adjustment and tilting of the seat surface.
  • the invention further comprises a wheelchair equipped with such a device.
  • Stand-up aids on chairs and armchairs which are intended to solve this problem, are known in many different versions.
  • This stand-up aid consists essentially of a device which pivots the seat plate by means of a linear drive from a slightly reclining rearward sloping normal sitting position in a slightly forward to the seat leading edge sloping position. At the same time, the seat plate is raised by a sufficient amount, leaving the user in an almost standing position Posture with feet on the floor, with slightly bent legs and the center of gravity partially transferred from the chair and thus can easily get out of the chair.
  • a stand-up aid mounted to a chair is described in US 5,803,545 which has an additional actuator.
  • the stand-up itself consists of a seat plate, a tilting frame on which the seat plate is rotatably mounted, a stationary hinge which connects the tiltable frame with a chair frame, a backrest, which is connected via a freely movable joint with the tiltable frame, a Lever which is rotatably connected to the backrest, a linear drive which is connected to the lever via a freely movable joint, and a spring element which is also rotatably connected to the freely movable joint.
  • the backrest and the associated seat plate is raised and simultaneously pivoted about the stationary hinge, so that the user in a nearly standing posture with his feet on the ground, with slightly bent legs and the body center of gravity partially from the chair is transferred away and thus easily get up from the chair.
  • a stand-up aid in the training of a chair for the disabled is also known. It is used in particular for getting up from the sitting position for people with muscle weakness, people with mobility problems without outside help. He resembles a conventional piece of furniture in the external appearance and is mounted on a central, designed as a vertical guide column lifting device on a run on rollers base frame adjusted. The seat itself can be adjusted to assist in getting up or sitting down by a certain angle, so that the disabled person does not get into reserve when getting up or sitting down. Both adjustment options are made possible independently by pressing pushbuttons in an armrest. About one on the base frame mounted tread plate you can lock the chair for the disabled.
  • a disadvantage of the invention described above is that it is a separate piece of furniture that is specially designed for the disabled.
  • the toilet seat itself is adjustable only in a vertical direction, so that the user must still spend additional leg power to move from the sitting position to an upright position. In addition, it requires the installation presented here a fixed installation, so that conversion measures are necessary.
  • the object of the invention is to make a stand-up help, which is particularly suitable for wheelchairs, and a wheelchair equipped with it safe to use and easy to design.
  • the main idea of the solution of the problem is to adaptively attach a lifting device, in particular for easy mounting on wheelchairs or other seating, with the help of the seat, which is suitable for sitting, is raised so that the person sitting on the seat taken into a standing position.
  • An essential idea of the invention is to use a simply constructed device in an existing and conventional chair, in particular a wheelchair, this device having a simple to build lifting device, which is for example electrically driven. It is very light in its overall weight, since it relies on the idea essential to the invention that the device repels the ground and thus the lifting device provides the corresponding counterforce. The considerable forces required for the lifting process can thus be introduced directly into the soil. At the same time the repulsion acts as a braking device, so that the chair, in particular wheelchair during movement does not leave its occupied position. This provides the user with the utmost security and makes him feel comfortable, easily and safely transferred from a sitting position to a standing position.
  • the lifting device can be flexibly designed in its width. Through simple displacement mechanisms, this can be adapted in a very simple way to the appropriate width of a wheelchair or a normal chair. It is only necessary to remove the seat of the wheelchair or chair, since the seat of the lifting device according to the invention has a special design, namely, in rigid training, a linkage to the lifting device and an articulated integration in the lifting device, so that carried out a desired tilting movement can be.
  • the lifting device has a centrally designed lifting device, so that the lifting device can be formed even with a small width. Thus, it can be easily used even on narrow chairs, but also to sports wheelchairs, which are narrow in itself.
  • the stroke length depends on the desired level of the stand-up aid. The further the person has to be brought into the desired standing position, the longer is the lifting device.
  • the device Since the device is realized in a very lightweight design, it is possible to continue to move the wheelchair by hand. Only a slight increase in weight (the wheelchair) is recorded.
