Definitions

  • the invention relates to a bathtub lift for the disabled, with a floor frame, at least one guide frame attached to it, a lifting plate supported by the latter, a lifting device arranged between the latter and the floor frame and operable with pressurized water, and a manual control valve for filling or emptying the lifting device, wherein the guide frame has two pairs of scissor arms arranged next to one another in the transverse direction of the bathtub and the scissor arms of each pair of arms are pivotally connected to one another in the middle, and in each case one scissor arm of a pair of arms is mounted at one end in a fixed pivot bearing on the base frame and at its other end in a rail attached to the lifting plate sliding sliding bearing and the other scissor arm of a pair of arms is mounted at one end in a fixed pivot bearing on the lifting plate and at the other end one in a fixed to the floor frame n Rail has sliding sliding bearing.
  • Such a bathtub lift is known from EP-A-0 074 460.
  • the problem with such a bath lift is that when the lifting plate is raised, the desired high position is automatically reached and this high position is not exceeded in order to avoid damage to the bath lift.
  • FR-A-2 146 098 shows a similar lift which is pneumatically operated and, according to a first alternative, has an adjustable mechanical stop in a rail which guides the roller of a scissor arm and, according to a second alternative, a limit switch instead of the mechanical stop to which Switch off the compressed air supply when the elevation of a lifting plate is reached.
  • a mechanical stop can cause the guide frame to bend. Stopping the compressed air supply device when reaching the high altitude has the same disadvantages as the lift described above.
  • the object of the invention is to further develop the known bathtub lift so that the lifting plate is stopped safely and precisely in a predetermined high position regardless of an actuation of the control valve, without impermissible forces being exerted on the guide frame.
  • a sliding piece is slidably received in at least one rail of the lifting plate in the movement path of the sliding bearing, that a crossbar engages in the movement path of the sliding piece and can be moved by it that the sliding piece Arranged near the end position of the sliding bearing corresponding to a certain high position of the lifting plate and arranged for entrainment by the sliding bearing during its last movement section and that the crossbar can be moved by the sliding bearing into an end position in which it can be moved onto an actuating member of a separate one in the Manual control valve leading pressure water line switched on or a shut-off valve integrated in the manual control valve acts to shut off the pressure water supply.
  • the pressure in the lifting device can be adapted to the respective load on the lifting plate.
  • the lifting device is only operated at the pressure required to lift the lifting plate. If the lifting plate is not loaded, the lifting device is filled with water, but the overpressure is low. If the lifting plate is now loaded, it lowers somewhat, but the shut-off valve opens immediately and the pressure in the lifting device increases and compensates for the load, the original desired high position being reached again.
  • the shut-off valve is separated from the manual control valve.
  • it is integrated in the manual control valve, e.g. B. by the actuator on the control lever of the hand control valve and resets the control lever in the neutral or shut-off position when the target high position of the lifting plate is reached.
  • Embodiments of the invention are that the effective length of the sliding piece between its end surface cooperating with the sliding bearing and the crossbar is adjustable and that the stroke of the crossbar is equal to that of the actuator and further in that the crossbar slidably penetrates an elongated hole in the rail and at Plant at one end of the elongated hole forms mechanical stop for the sliding piece.
  • the outer end of the actuating member has a transverse slot which is penetrated by the transverse rod, and the inner end of the actuating member carries the valve closing body.
  • a valve closing body of the separate shut-off valve has an annular groove in which an elastic ring engages, the outer periphery of which is clamped in a housing of the shut-off valve and that the elastic ring has a substantially flat shape in the open position of the shut-off valve and a substantially in the closed position approximately conical shape with restoring effect.
  • an adjusting device effective in the adjustment direction is provided, which is preferably designed in the form of a coaxial screw arranged in the bottom surface of the transverse slot of the actuating member.
  • the bathtub lift generally designated 10, has a base frame 12, two guide frames 14, 16 arranged thereon and a lifting plate 18 supported by the latter.
  • Each guide frame 14 or 16 consists of two pairs of scissor arms 20, 22, of which the two scissor arms 20 on the lower one Ends in joints of the floor frame and the upper ends are designed as sliding bearings 26 which can be displaced in rails 24 with a C-shaped cross section.
  • the two other scissor arms 22 of each guide frame 14 are pivotally mounted on the lifting plate 18 but not displaceably, while the lower ends have sliding bearings 30 which are displaceable in rails 32 fastened to the floor frame 12.
  • the two scissor arms 20, 22 of each guide frame 14 and 16 are connected to one another in the middle by a joint 34.
  • the two joints 34 can be connected by a rod 36, as illustrated in FIG.
  • the lower sliding bearings 30 of the guide frame 14 are articulated to the corresponding lower sliding bearings 30 of the other guide frame 16 via a strut 64 each, so that a gear coupling is achieved which ensures vertical adjustment of the lifting plate 18.
  • lifting devices 38, 40 each designed as pressurized water hoses, each of which is assigned to one of the guide frames 14, 16.
  • Fabric hoses with a diameter of approximately 80 mm to 100 mm are used.
  • the ends of the hoses are sealed and screwed to the base frame 12 and the lifting plate 18.
  • Connecting hoses 42 which start from a manual control valve 44 and are connected in parallel, each open into the upper ends of the lifting devices 38, 40.
  • a shut-off valve 46 is attached to the underside of the lifting plate 18 and is connected to a pressurized water supply hose 48.
  • the outlet of the shut-off valve 46 is connected to the manual control valve 44 via a connecting hose 50.
  • a drain hose 49 (FIG. 5) leads z. B. in an adjacent sink.
  • the rails 24 for the upper sliding bearings 26 have in the region of the guide frame 16 transversely oriented longitudinal slots or slots 52 into which outwardly bent and mutually transversely aligned arms of a U-shaped cross rod 56 engage, the yoke-shaped offset 58 of the actuating member 60 of a valve body 74 of the shut-off valve 46 penetrates.
  • a sliding piece 62 is inserted, the length of which determines the desired high position of the lifting plate 18.
  • These sliding pieces are plastic bodies cut to length, of which several can also be arranged one behind the other in such a way that the sliding bearings 26 push the sliding pieces 62 against the arms 54 immediately before the desired target high position of the lifting plate 18 is reached.
  • the transverse rod 56 is also moved to the left by this distance and the actuating member 60 is pushed into the shut-off valve 46 until it is closed . At this moment, the pressure water supply is interrupted and the stroke of the lifting plate 18 is ended.
  • the movement distance of the cross bar 56 is here equal to the adjustment stroke of the actuating member 60.
  • the control lever 51 of the hand control valve 44 has three positions. In the middle neutral or shut-off position according to FIG Lifting devices 38, 40 blocked. In this position, the lifting plate can be locked at any desired height. In one swivel position, the lifting devices 38, 40 are connected to the emptying hose 49, so that the lifting plate 18 lowers. In the other pivoting position of the control lever 51, the lifting devices are connected to the pressurized water supply hose 48 via the open shut-off valve 46, so that water can flow in, but at a pressure which corresponds to the respective load on the lifting plate 18.
  • Fig. 4 illustrates the shut-off valve 46 in section.
  • a through hole 68 is provided with a constriction 70, which forms a valve seat.
  • a transverse bore 72 opens into the through bore 68 for connecting the pressurized water supply hose 48.
  • the connecting hose 50 is connected to the left-hand end of the through bore 68 downstream of the valve seat 70.
  • a valve closing body 74 of the actuating member 60 is mounted in the through bore 68 so as to be displaceable in the longitudinal direction. At the front end, the valve closing body 74 carries a rubber washer 76.
  • the valve closing body 74 has an annular groove 78 into which an elastic ring 80 engages, the outer circumference of which is pressed sealingly against the right-hand end face of the housing 66 by a screw sleeve 52.
  • the valve closing body 74 is formed in one piece with the actuating member 60 protruding from the housing 66, the end of which has a transverse slot 84 which is open at the end and into which the offset 58 of the U-shaped transverse rod 56 engages.
  • an adjusting device 86 is provided in the form of a coaxial screw, which allows a fine adjustment of the desired high position of the lifting plate 18.
  • the valve closing body 74 with the actuator 60, the cross bar 56 and the sliding pieces 62 are held by the elastic ring 80 in the positions shown in FIG. 4, in which the shut-off valve 46 is open. In this position, the ring 80 has a flat shape. If the sliding pieces 62 now press the cross rod 56 onto the actuating member 60, the latter moves a few millimeters until the rubber disk 76 of the valve closing body 74 presses against the valve seat 70. The ring 80 deforms elastically and takes on a conical shape with a restoring effect. If the lifting plate 18 is now subjected to a greater load or if the manual control valve 44 is moved into the lowered position, the valve closing body 74 moves back into the open position due to the prestress caused by the elastic ring 80 (FIG. 4).
  • FIG. 5 shows a modification in which the shut-off valve 46 'is integrated in the manual control valve 44.
  • the pressure water supply hose 48 opens directly into the manual control valve 44.
  • a connecting hose 50 is omitted.
  • the crossbar 56 'here consists of a short rod which is fastened in a sliding piece 88 which is displaceable in the rail 24 which is C-shaped in section.
  • the sliding piece 88 carries a longitudinal rod 62 ', the end of which has a screw thread 90, by means of which it is screwed into a further sliding piece 92, which is also guided displaceably in the rail 24.
  • the arrangement 56 ', 88, 62', 92 represents a spacer, which corresponds to the function of the sliding piece 62, but the length of which is infinitely adjustable. For adjustment, the arrangement 56 ', 88, 62', 92 is removed from the rail.
