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
  • the Guide frame has two pairs of scissor arms arranged next to each other at a distance and the scissor arms of each pair of arms are pivotally connected to one another in the middle and each have a fixed pivot bearing on the base frame or the lifting plate at the ends and a sliding bearing which can be moved on a rail.
  • Such a bathtub lift is known from EP-A-0 074 460.
  • the lifting of the lifting plate must be controlled very carefully if a stop is to be achieved in the target position that is flush with the tub rim. Disabled people are often unable to do this.
  • the lifting plate is moved to a design-related maximum position, which may be defined by mechanical stops: without switching the control valve, the full supply pressure builds up in the lifting device, which can damage the bathtub lift.
  • 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.
  • shut-off valve is switched on in the pressurized water line leading to the manual control valve or is integrated in the manual control valve, with the valve actuator of which an actuating element cooperates which, when a predetermined lifting height of the lifting plate is reached, in a position holding the valve actuator in the closed position of the shut-off valve Position.
  • the shut-off valve is controlled according to the invention in direct or indirect dependence on the height position of the lifting plate.
  • a directly dependent control could be carried out by a pull chain, the upper end of which is attached to the valve actuator of the shut-off valve attached to the lifting plate and the lower end of which is attached to the floor frame.
  • Indirectly dependent control could take place, for example, by using the angle between the viewing arms that changes when the lifting plates are raised.
  • the shut-off valve would be on a scissor arm to attach, whose valve actuator comes to rest on an attachment of the other scissor arm when the desired stroke position of the lifting plate is reached.
  • the distance between the lifting plate and a point of a scissor arm or the base frame and a scissor arm that changes when the lifting plate is lifted could also be used as a control variable at a distance from the pivot bearing of the scissor arm.
  • the displacement of the sliding bearing of a scissor arm in the corresponding rail is particularly advantageous to control the shut-off valve by closing the shut-off valve in the position of the sliding bearing along the rail of the lifting plate or the base frame via the actuating member, which corresponds to the desired up position of the lifting plate.
  • the sliding bearing or an attachment attached to it or the scissor arm in its neighboring area abuts against the actuating member, which is now taken along and carries out a short stroke equal to the adjustment stroke of the shut-off valve and closes the latter.
  • the invention has the advantage that the user does not have to pay attention to the achievement of the correct set up position of the lifting plate during the lifting process, but is rather achieved automatically by closing the shut-off valve and preventing a further supply of pressurized water.
  • the actuating member is longitudinally spaced from the sliding bearing in its actuating position and is bridged by an exchangeable and / or longitudinally adjustable spacer, then the set up position of the lifting plate can be adjusted very simply and infinitely and adapted to the respective tub height .
  • the spacer is simply inserted into the rail, which is preferably C-shaped in the profile.
  • the pressure in the lifting device can be adapted to the respective load on the lifting plate.
  • the lifting hoses that are preferably used are only being operated at the pressure required to lift the lifting plate. If the lifting plate moves empty upwards, the lifting hoses are filled with water, but the overpressure is very low. If the lifting plate is now loaded, it lowers somewhat, but the shut-off valve opens immediately and the pressure in the lifting hoses increases and compensates for the load, whereby the original set position is reached again.
  • the shut-off valve can be separated from the manual control valve, but can also be integrated into it, for example by the actuating element engaging the control lever and moving it into the neutral position resets when the set position of the lifting plate is reached.
  • 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 consists of two pairs of scissor arms 20, 22, of which the two scissor arms 20 at the lower ends in joints of the Bottom frame and the upper ends than in U-rails 24 sliding bearings 26 are executed.
  • the two other scissor arms 22 of each guide frame 14 can be pivoted at the top of the lifting plate 18, but are not displaceably mounted, 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 pair of scissor arms 14 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. 2.
  • 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 a horizontal adjustment of the lifting plate 18.
  • hoses 38, 40 Between the base frame 12 and the lifting plate 18 there are two pressurized water hoses 38, 40, each of which is assigned to one of the guide frames 14, 16. These hoses 38, 40 represent the lifting device. Fabric hoses are used which have a diameter of approximately 80 mm to 100 mm. 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, open out each in the upper ends of the lifting hoses 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 line 49 extends from the manual control valve 44 (FIG. 5), which e.g. can be hung in an adjacent sink.
  • the rails 24 for the upper sliding bearings 26 have in the region of the guide frame 16 transversely aligned longitudinal slots or elongated holes 52 into which outwardly bent and mutually transversely aligned arms of a U-shaped actuating member 56 engage, the yoke 58 of which is the valve actuator 60 of a valve body 74 of the Shut-off valve 46 passes through.
  • the actuating member 56 is biased into a position in which the shut-off valve 46 is open, that is to the right in FIGS. 1 and 2, the arms 54 coming to the right in the elongated holes 52.
  • a spacer 62 is inserted, the length of which determines the set position of the lifting plate 18.
  • spacers are plastic bodies cut to length, of which several are also facing can be arranged one behind the other in such a way that the sliding bearing 26 push the spacers 62 against the arms 54 immediately before the desired set position of the lifting plate 18 is reached. If the upper sliding bearings 26 move only a few mm to the left during the further lifting of the lifting plate (FIGS. 1 and 2), the actuating member 56 is also moved to the left by this distance and the valve adjusting element 60 is pushed into the shut-off valve 46 until the valve closes is. At this moment, the pressure water supply is interrupted and the stroke of the lifting plate 18 is ended. The movement distance of the actuator 56 is equal to the adjustment stroke of the valve actuator 60.
  • a lying U-profile with a retaining web pointing upwards from the bottom-side U-leg is used for these upper rails.
  • the opening width of the profile is approximately equal to the height of the spacer or spacers 62.
  • the control lever 51 of the hand control valve 44 has three positions. In the middle position according to FIG. 1, the lifting hoses 38, 40 are shut off. With this position, the lifting plate can be locked in any desired height position. In one swivel tion, the lifting hoses 38, 40 are connected to the drain line 49, so that the lifting plate 18 lowers. In the other pivoting position of the actuating lever, the lifting hoses are connected to the pressurized water supply line 48 via the open shut-off valve 46, so that water can flow into the hoses, but with a pressure that corresponds to the respective load on the lifting plate 18.
  • Fig. 4 illustrates the shut-off valve 46 in section.
  • the housing 77 of the shut-off valve 46 has a through bore 68 with a constriction 70, which forms the valve seat.
  • a transverse bore 72 opens into the bore 68 for connecting the supply line 48.
  • the hose 50 is connected to the left-hand end of the through bore 68 downstream of the valve seat 70.
  • a valve body 74 is slidably mounted in the longitudinal direction, the front end surface of which carries a rubber washer 76.
  • the stem of the valve body 74 has an annular groove 78 into which an elastic ring 80 engages, the outer circumference of which is pressed by a screw sleeve 82 in a sealing manner against the right-hand end face of the valve housing 66.
  • the valve body 74 is formed in one piece with the adjusting 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 yoke 58 of the U-shaped actuating member 56 engages.
  • an adjusting screw 86 is screwably received, which permits a fine adjustment of the desired high position of the lifting plate 18.
  • the valve body 74 is held by the elastic ring 80 in the position shown in FIG. 4, in which the shut-off valve 46 is open. In this position, the ring 80 has a flat shape. Now presses the shut-off device 56 on the valve adjusting member 60, this shifts by a few mm until the rubber disk 76 of the valve body 74 shuts off the valve seat 70. The disk 80 deforms and takes on a conical shape. If the lifting plate 18 is now subjected to a greater load or if the control valve 44 is moved into the lowering position, the valve body 74 returns to the open position due to the prestressing 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 pressurized water supply line 48 opens directly into the manual control valve 44.
  • the connecting line 50 is omitted.
  • the actuator 56 ' here consists of a short cross bar 56' which is fastened in a sliding body 88 which is displaceable in the section 24 of the C-shaped rail 24.
  • the cross bar 56 ' engages in the cross slot of the V entilverstellgliedes 60 a.
  • the sliding body 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 body 92, which is also guided displaceably in the rail 24.
  • the arrangement 56 ', 88, 62', 92 represents the spacer, the length of which is infinitely adjustable and which can be removed from the rail 24 for adjustment.
