Definitions

  • the invention relates to a bathtub insert with a floor frame, a lifting plate, at least one guide device arranged in between, and lifting devices, the guide device each having two scissor-like pivot frames that each have two coaxial fixed bearings on the floor frame or lifting plate and two coaxial sliding bearings Have lifting plate or floor frame and wherein at least one pivot frame of the guide means engages a spring arrangement at least in the last pivoting phase of the pivot frame during the upward movement of the lifting plate.
  • the lifting plate must be raised to the level of the bath tub rim if a physically disabled person wants to get onto the lifting plate. The lifting plate is then lowered into the bathing position with the person.
  • Such bathtub inserts are shown in DE-A-3324294 and US-A-4,660,234. Deep bathtubs require a large lift of the lifting plate.
  • the swivel frames come into such steep positions that self-clamping can occur, especially if the sliding bearings have slide elements guided in rails.
  • the lifting plate is then no longer supported by the lifting device and can drop suddenly at any point in time if the movement of the person carried by the lifting plate loses self-locking.
  • the object of the invention is to provide a bathtub insert in which the lifting plate can be lowered smoothly from the raised position with the swivel frame standing upright.
  • a bathtub insert without a base frame and with a lifting device arranged horizontally under the lifting plate is known, in which a spring arrangement in the form of one or two tension springs is provided, which connects the upper sliding bearing ends of the swivel frame to the upper fixed bearing - Drag ends.
  • the remote arrangement pulls the lifting plate up. In a steep position of the swivel frame, the spring arrangement would rather support self-clamping.
  • a bathtub insert is known from US-A-3,106,723, in which the lower ends of the swivel frame are stationary and the upper ends are displaceable.
  • the lifting plate is connected via a spring arrangement to the upper ends of both swivel frames so that it is held in a central position.
  • the spring arrangement also pulls the lifting plate up here.
  • the spring arrangement according to the invention is tensioned during the upward movement of the lifting plate.
  • the greatest stored spring force is available at the start of the lowering movement of the lifting plate and acts in the direction of the downward swiveling of the swivel frame, preventing possible jamming of the sliding bearings.
  • the force of the spring arrangement advantageously acts in the direction of the sliding movement of the sliding bearings, because then a maximum effect is achieved with the lowest spring force.
  • the spring arrangement can, for example, be designed as a leaf or leg spring and be mounted in the joint area of the two swivel frames in such a way that the spring tensions between the two frames when the angle is reduced. It is also within the scope of the invention to use a tension spring, for example in the form of a strong rubber band, which is attached to the leg of a swivel frame associated with the sliding bearings and is attached with its other end to a fixed point on the lifting plate or the base frame, that the sliding bearings from their fixed bearings be pulled away.
  • a tension spring for example in the form of a strong rubber band, which is attached to the leg of a swivel frame associated with the sliding bearings and is attached with its other end to a fixed point on the lifting plate or the base frame, that the sliding bearings from their fixed bearings be pulled away.
  • a particularly preferred embodiment of the invention is that the spring arrangement has a straight rod, on which a helical compression spring is arranged, which presses at one end against a head of the rod, which forms a stop for the sliding bearing region of the pivot frame and that the other end of the Rod is axially displaceably guided in a bore or a channel of a fastening fitting, which has a front surface and a rear surface and the bore or the channel extends between the front and rear surfaces and that the other end of the helical compression spring is supported on the front surface and one on other end of the rod provided foot engages behind the rear surface of the mounting bracket.
  • the helical compression spring is preferably pretensioned, so that the foot of the rod is also supported on the rear surface of the fastening fitting.
  • This mounting bracket is preferably housed within a rail that also carries a sliding bearing of a swivel frame.
  • the sliding bearing or a driver moved by it thus comes into contact with the head of the rod of the spring arrangement during the last pivoting phase of the pivoting frame and displaces the rod with axial compression of the helical compression spring.
  • This version is advantageous because it only requires a small installation length. The space required for this is always available between the bearings of the two swivel frames of each guide device, which are on the same level, even if the swivel frames are very steep.
  • a bathtub insert 10 consists of a floor frame 12, a lifting plate 14, two guide devices 16 in the form of two articulated swivel frames 18, 20, which are synchronized by means of handlebars 22 for joint movement, and two pressurized water hoses 24, the ends of which are on the floor frame 12 and are attached to the lifting plate 14.
  • Both swivel frames 18, 20 are rectangular frames which are articulated to one another in the central region by an articulated rod.
  • the swivel frame 20 is narrower than the swivel frame 18 so that it fits into the lifting plate 14 in the lowered position thereof.
  • the outer pivot frame 18 has two upper fixed bearings 26 and two lower sliding bearings 28 which are guided in rails 30 on the base frame 12.
  • the inner swivel frame 20 has two lower fixed bearings 32 and two upper sliding bearings 34 which are guided in corresponding rails on the underside of the lifting plate 14.
  • a spring arrangement 36 is attached in the form of a strong rubber rope, the other end of which leads to the adjacent upper cross member between the fixed bearings 26 of the outer pivot frame 18 of the other guide device 16. This end of the rubber cord can also be attached directly to the underside of the lifting plate 14.
  • each guide device 16 can be set very steeply without the sliding bearings 34 jamming in the rails 30 when the pressure water hoses 24 are subsequently relieved, since the spring arrangement 36 prevents or overcomes such jamming.
  • FIGS. 3 and 4 illustrate a modified embodiment of a spring arrangement 36 which has a fastening fitting 38, the cross section of which corresponds approximately to the clear cross section of the rail 30 on the bottom side of the lifting plate 14 and which extends over a certain length within this rail 30.
  • a straight rod 40 extends through the entire length of the fastening fitting 38 and passes through a bore 42 provided in the rear part of the fastening fitting 38 with sliding play.
  • the bore 42 extends through a transverse wall of the fastening fitting 38, which is adjoined at the front by a channel-like opening 44 which is open at the top and which has a somewhat larger cross section than the bore 42.
  • a cylindrical helical compression spring 46 is guided in a longitudinally displaceable manner on the rod 40, one end of which is supported on a nut screwed onto the rod 40, which forms a head 48 for the rod 40.
  • the other end of the helical compression spring 46 rests on the front surface of the transverse wall having the bore 42.
  • the helical compression spring 46 is installed with pretension so that a nut screwed onto the rear end of the rod 40 is supported on the rear surface of this transverse wall. This nut forms a foot 50 of the rod 40.
  • the mounting bracket 38 is in the form of a plastic body which is screwed onto a side wall of the rail 30 by means of two screws 52.
  • the inner swivel frame 20 pivots each of the two guide devices 16 in a clockwise direction upwards and the two sliding bearings 34 in the form of sliding pieces running in the rails 30 come into contact with the head 48 of the displaceable rod 40.
  • the rod 40 is shifted to the left and the compression spring 46 is compressed.
  • the force of the spring 46 is dimensioned such that the tendency of the sliding bearings 34 in the rails 30 to clamp due to the steep position of the swivel frames 18, 20 is overcome.
  • the entire spring arrangement 36 then has approximately twice the length. Thanks to the significant length of the mounting bracket 38 within the rail 30, the compression spring 46 is positively guided, namely in that it is stabilized by the inner rod 40, which has a sliding guide in the bore 42 at the rear end, while the channel-like opening 44, the coil spring 46 leads directly to the front end of the mounting bracket 38.
