Definitions

  • the invention relates to a stand-up aid for the disabled with a lower and an upper frame part and a height-adjustable support section relative to the lower frame part, which is attached to a support section.
  • stand-up aids exist, for. B. furniture in the form of stand-up chairs, chairs or lifts.
  • a catapult seat as a folding attachment for a series chair
  • the seat energy stored when sitting can assist in getting up.
  • the angle of inclination of the folding attachment is changed.
  • Motorized stand-up chairs enable you to stand up thanks to a seat that lifts and tilts upwards.
  • the seat and backrest move together with the armrests as one unit with respect to a lower frame part.
  • a platform is raised and lowered mechanically, electromechanically or by water pressure between the pool edge and the tub floor.
  • the working times when standing up and sitting are relatively long, and the noise of the motor drive can have a stigmatizing effect.
  • the construction is relatively complex and often gives a negative appearance because the mechanics are visible in some positions.
  • the object of the invention is to provide a stand-up aid of the type mentioned at the outset which, with a simple construction and simple operation, leaves the appearance essentially unaffected.
  • the lower frame part has at least one upward, high section in which a flexible element runs, that the flexible element is connected to a part of the support section and that the flexible element for tensioning the same and lifting the support section is connected to a pulling device accommodated in a box-like carrier.
  • the frame itself serves to accommodate essential parts of the adjustment mechanism, so that the structure is simple and does not have a disruptive effect. Additional cover elements are saved.
  • the traction device has at least two clamping units connected in parallel, both of which are activated when standing up and when lowering, the lowering and the lifting of the user can proceed relatively quickly.
  • a favorable use of energy results from the fact that an electrically operated mechanism or hydraulic system is provided which is designed such that so that one of the clamping units is preloaded in an unloaded state after getting up.
  • An advantageous, simple structure consists in that the lower frame part has two parallel upwardly directed hollow sections, onto which two coordinated, downwardly directed sections of the upper frame part are telescopically pushed, that the downwardly directed sections are provided with coupling members which protrude through slots into the interior of the upward sections and that the coupling links are connected to the lower end of an upward leading section of the cable which is pulled upwards when standing up by means of the pulling device, and that the supporting section on the upper frame part is connected to the latter is slidably attached. With the pulling device, the upper frame part, which is displaceable against the lower frame part, is lifted and with it the support section.
  • a simple structure with a favorable arrangement of the box-like carrier consists in that the lower frame part has a horizontal high foot part, the cavity of which is connected to the cavity of the upwardly directed sections, that the box-like carrier is attached to the foot part and that the top part leading section of the cable is guided downwards via a deflection element arranged in the respective upwardly directed section of the lower frame part and is connected to the pulling device via further deflection elements.
  • a suitable design in this structure is that it is designed as a free-swinging chair, in which the support section is designed as a seat, which is articulated in its front region between the two downward sections of the upper frame part, that the two down form leading sections above the seat on both sides to the rear armrests, on which an actuating element for triggering the pulling device and reaching the stand-up position is arranged and which carry a backrest that another rope is connected to an upper region of the upward section of the lower frame part which is guided through the armrests to the rear area of the seat and connected to it.
  • a tilting movement is also achieved with simple means, the entire mechanism being accommodated in a favorable manner.
  • the box-like carrier with the pulling device is arranged under the support surface designed as a seat surface, that the rope is arranged laterally on the front section of the seat surface by deflecting elements laterally on the two upward sections of the lower one Slots provided in the frame part is guided therein, runs upward and is guided downward via respective upper deflection elements and is fixed to an anchoring element with an end region in the lower frame part.
  • the lower and the upper frame part can merge into one another, the height of the seat surface being adjustable with the box-like carrier.
  • the seat can be designed to be tiltable in a simple manner in that the upper frame has armrests, one from the bottom of each Another rope is guided to the rear area of the seat surface pivotably mounted in its front area, and that a further tensioning unit is provided under the seat area, which interacts with the other ropes on both sides in such a way that the rear area of the seat area experiences an upward force.
  • a secure stand and good mobility are achieved in that the foot section of the lower frame part has four plate-like, sliding or rolling feet.
  • the stand-up aid offers an aesthetically pleasing appearance when the support surface is lowered and raised.
  • the drive components are not visible in any of the operating states. This maintains a simple and elegant character.
  • the low-noise actuation that is active when lifting and lowering is advantageous as an application advantage for gas springs. Since the prestressing of one or more gas springs always takes place after erection at a point in time when there is no direct contact between the user and the stand-up aid, the lowering process can take place without delay.
  • a stand-up chair is shown in perspective, which has a chair frame with a lower frame part 4 and an upper frame part 3, a support surface in the form of a seat surface 2, a backrest 1 attached to the upper frame part 3, foot pieces 6 and plate-like feet 7.
