Definitions

  • the invention relates to a bath lift for the disabled with, by means of a lifting plate that can be raised and lowered on a frame and is operated by a hydraulic lifting device, and a manually operated valve device, the valve housing of which has an inlet valve and an outlet valve, the valve stem of which can be actuated by pivotable buttons.
  • Such a bath lifter is known from DE-A-33 37 536.
  • the two buttons are designed as push buttons, which are each pivotally mounted on the valve housing on one side. Details of the valve device cannot be found in this document.
  • the two valve lifters are of identical design and are displaceably mounted with parallel axes in the valve housing and their valve disks each by means of built-in springs are biased towards the lifting plate against respective valve seats, a pressurized water supply connection with an annular space upstream of the valve seat of the inlet valve and the connection leading to the lifting device communicating with a second annular space downstream of the valve seat of the inlet valve, and this second annular space via a housing bore with an upstream annular space of the Exhaust valve communicates, whose downstream annular space is connected to an outlet opening of the valve housing, and that the two buttons are formed on a one-piece rocker, which is pivotally mounted about a transverse axis located centrally between the displacement axes of the two valve lifters and two actuating surfaces at the same distance from this transverse axis has, which are in a neutral position of the rocker closely adjacent above each of the two valve tappets in their closed positions.
  • the inlet valve is actuated in a pressure-dependent manner.
  • a stroke limitation of some kind is provided for the upward movement of the lifting plate, for example in the form of a mechanical stop, which prevents the lifting plate from being raised further. If the lifting plate now reaches this stroke end position, the pressure of the water supply builds up in the lifting device and pressure equalization takes place within the inlet valve, which leads to the valve tappet coming into its closed position due to the valve spring.
  • a pressure limiter is connected upstream in the case of a high pressure in the domestic water line in order to keep the loads on the bathing lift within permissible limits.
  • the outlet valve can generally also be used for the above purpose as a safety valve for pressure limitation.
  • the closing force of the spring acting on the valve tappet only has to be set to a value such that the valve disk can be lifted off the valve seat when an adjustable water pressure in the lifting device is exceeded.
  • this response pressure is set to a value in the range from 3 to 6 bar.
  • the control arm is preferably displaceable parallel to the lifting plate plane by a sliding bearing of a scissor frame of the frame which is displaceably guided along the lifting plate in the region of the lifting end position of the lifting plate, and a 90 ° displacement converter is provided between the control arm and lifting element, so that the control arm moves in parallel to the lifting plate an actuating stroke of the lifting element that takes place approximately at right angles to it is implemented.
  • the inlet valve becomes when the stroke end position of the lifting plate is reached closed depending on the path and a particular advantage of this invention is the small stroke of the valve lifter of less than 2 mm. So even if the user actuates the rocker for the function of moving the lifting plate upwards, the control arm with the lifting element of the valve device ensures that the valve tappet reaches its closed position safely. Any movement games of the rocker can not affect this forced shut-off of the inlet valve.
  • the lifting element consists of a pivoting lever which is pivotally supported at one end adjacent to the transverse axis of the rocker and at the other end has a wedge surface which cooperates with the control arm, the pivoting lever in a region between its Attacks the ends of the valve lifter.
  • the pivot lever is thus secured at one end on the valve housing against displacement, but there is a pivoting mobility.
  • the swivel lever is supported by the valve lifter. So if you press the button on the rocker, the valve tappet is moved to the open position and the swivel lever is swiveled slightly downwards.
  • the valve tappet 52 is moved downward and the connecting piece 46 leading to the lifting hose 26 communicates with the connection 44 leading to the pressurized water supply, so that the lifting hose 26 is filled with pressurized water and the lifting plate 24 is raised becomes. If the user releases the rocker 76, the valve spring 56 ensures that the inlet valve 48 is closed, the valve tappet 52 returning the rocker 76 to its neutral position. On the other hand, if you press the keypad 82 of the rocker 76, the outlet valve 50 opens and the lifting hose 26 empties through the housing bore 70 and the two annular spaces 64, 66 of the outlet valve 50, the water through the Outlet opening 68 runs out.
  • the outlet valve 50 is preferably also designed as an overpressure safety valve, the strength of the valve spring 56 being dimensioned such that when an adjustable working pressure in the range of approximately 3 to 6 bar is exceeded, the valve 50 opens, so that the pressure in the lifting hose 26 is relieved.
