Definitions

  • the invention relates to a lifter usable in bath tubs for the disabled, consisting of a base plate, a guiding device consisting of two scissor-like articulated frames and a lifting plate guided by this, and a lifting device for lifting and lowering the lifting plate, the two frames each having two parallel longitudinal legs and have at least one cross leg and each frame on one of the plates has two coaxial immovable joints and on the other plate two coaxial ones in, for example C-profile rails have guided displaceable joints.
  • Such a lifter is known from EP-A-0131741.
  • the sliding joints are formed by rollers that run in the side open U-rails.
  • the rollers of the outer frame are arranged laterally outside the frame and the rollers of the inner frame are on the inside of the longitudinal legs.
  • All legs of the two frames consist of rectangular profiles made of stainless steel.
  • the longitudinal legs must be welded or flanged to the cross legs.
  • holes must be drilled and the articulated rollers must be mounted on axles and the axles attached to the longitudinal legs of the frame.
  • the known lifter still has some shortcomings. The roles require quite high building rails, which the Limit the lowering of the lifting plate in that the cross legs come to rest on these rails. In the lowest possible position of the lifting plate, the longitudinal legs of both frames are still inclined at a certain angle. A further lowering of the lifting plate is therefore not possible for design reasons.
  • the object of the invention is to further simplify the lifter of the type mentioned, to ensure greater stability and to further reduce the ground clearance of the lifting plate in the lowered position.
  • the two frames engage in the lower position of the lifting plate in such a way that one frame forms an inner frame which engages in the interior formed by the two delimiting planes of the outer frame that the middle Vertical plane of each longitudinal leg of both frames coincides with that of a rail, that the open side of the rails faces away from the respective plate, that the articulation axes of the displaceable joints are offset in the direction of the respective rails at a distance from the central longitudinal axis of the longitudinal legs, that each articulation consists of two from opposite side surfaces of each longitudinal leg in each case protruding pin is formed and that the pins are arranged immovably on the respective longitudinal leg.
  • the axes of the rollers are arranged in the middle of the width of the longitudinal legs.
  • the roll diameter must necessarily be larger than the center distance from the end of the frame. This requires relatively high upright U-rails.
  • the offset of the pins according to the invention has the advantage that quite flat C-rails can be used and since the pins are no longer rotatable, they can have a much smaller diameter, which also has a favorable effect on the overall height of the rails.
  • the invention makes it possible for the inner frame to be accommodated completely within the contour of the outer frame when the lifting plate is in its lowered position. Although the longitudinal legs are no longer next to the rails, but above or below the rails, the minimum floor clearance of the lifting plate which is in the lowered position is reduced.
  • Another advantage is the improved guidance of the two frames, which has a positive effect on the stability. While up to now each longitudinal leg was only guided on one side over the lateral roller on the sliding joint side, this leg is now guided on both sides. This guarantees absolute freedom from wobble, especially in the high position.
  • each longitudinal leg forms a one-piece plastic molded part with its pin
  • each longitudinal leg has a hook-like extension on the sliding joint side, which extends essentially at right angles to the longitudinal extension of the longitudinal leg, namely directly at the end of the longitudinal leg this extension the two pins are arranged.
  • the axial offset of the pins from the middle of the leg is so large that the pins - seen from the side - are for the most part outside the contour of the longitudinal legs.
  • the hook-like extension with the two lateral pins preferably has a dimension measured transversely to the longitudinal direction of the longitudinal legs, approximately the same as the pin diameter measured in this direction.
  • the rail has a low, flat C-profile with an opening width slightly larger than the width of the longitudinal legs, so that they dip slightly into the rails when the lifting plate is lowered.
  • each of the two frames forms an integral plastic molding, the longitudinal and transverse legs each made of solid fiber-reinforced plastic.
  • Each of the two frames is manufactured in its own mold as an injection molded part. This results in rounded edges and also the holes for the fixed bearings and the central crossbar can be molded in, so that no rework is required.
  • the continuous articulated rod connecting the two frames centrally to one another is thread-free, that its length is less than the outer width of the outer frame and that the articulated rod has one end inserted into the longitudinal leg of the outer frame Stopper.
  • a blind bore is preferably provided in a longitudinal leg.
  • the crossbar is then a simple round steel, which is inserted through the three holes in both frames and into the blind hole, after which the hole only needs to be closed at the opposite end by a screw plug or a locking plug.
  • the pins preferably have flat support surfaces, which come to rest flat on the rails in the raised and lowered positions of the lifting plate, so that the surface pressure on each pin is reduced.
  • the two frames 14, 18 are in their respective positions 14' and 18 'parallel and parallel to the base plate 12, the inner frame, with the exception of its sliding joints 20, being fully immersed in the contour of the outer frame 18.
  • the part of the outer frame 18 which extends downward from the articulated rod 20 is somewhat longer than that of the inner frame 14.
  • the latter has a cross leg 30 which integrally connects its two longitudinal legs 28.
  • a cross leg is missing at the opposite end, so that the outer frame forms an open U.
  • the inner frame 14 consists of two longitudinal legs 32, a lower cross leg 34 and an upper cross leg 36 in the form of a wide, ribbed stiffening plate. The inner frame 14 is thus closed.
  • the rails 22 consist of flat profiles, the open side of which faces away from the respective plate 12 or 24.
  • the opening width of the C-rails is slightly larger than the thickness of the two longitudinal legs 28 of the outer frame 18 and the longitudinal leg 32 of the inner frame 14 measured in the transverse direction of the lifter. Both legs 28, 32 engage slightly in the rails 22.
  • the legs 28, 32 are centered on the longitudinal direction of the rails 22.
  • the two frames 14, 18 consist of integrally molded glass fiber reinforced plastic parts and the sliding joints 20 are integrally formed. They consist of a hook-like extension 38 which is arranged at the outermost end of the respective longitudinal leg 28 or 32 and extends approximately at right angles to the longitudinal direction and on which two pins 40 projecting laterally beyond the side surfaces of the longitudinal leg 28, 32 are provided.
  • the shape of these pins 40 has two planar support surfaces 42, 44 diverging at an angle of approximately 50 °, which run into a circular cylindrical surface 46 with a continuous transition which connects the two support surfaces 42, 44 and extends over a circumferential angle of approximately 230 ° .
  • the pins 40 thus have approximately an elongated teardrop shape.
  • the divergence angle of 50 ° corresponds to the pivoting angle of the frames 14, 18 between their low position and their high position.
  • the support surfaces 44 of the pins 40 facing away from the frame extend parallel to the longitudinal direction of the frames 14, 18. In the lower positions 14 ', 18' of both frames, these are supported with their support surfaces 44 on the base legs of the rails 22 on the base plate 12 and lifting plate 24. In the raised position of the lifting plate 24, the two other support surfaces 42 facing the frame come into effect and lie flat against the mutually facing C-legs of the rails 22 because the lifting hose 26 pushes the two plates 12, 24 apart. In both end positions, the flat support surfaces 42, 44 of the pins 40 avoid line contacts and ensure a lower surface pressure.
  • the diameter of the circular cylindrical surface 46 connecting the two flat support surfaces 42, 44 corresponds to the clear height of the rail 22 and the outer width of the extension 38 with the two pins 40 corresponds approximately to the clear width of the rail 22.
  • a recess 48 is formed which extends along the two support surfaces 42, 44 and a respective subsequent circumferential angle into the cylinder surface 46.
  • This recess 48 can be designed as a circumferential groove and serves to receive the heads of fastening rivets with which the rails 22 are fastened to the plates 12, 24.
  • the two longitudinal legs 32 of the inner frame 14 have coaxially aligned bores in the central region, with which a blind hole is formed in a longitudinal leg 28 of the outer frame 18 in the assembled state of the lifter and a stepped through hole is formed in the opposite longitudinal leg 28 of this outer frame 18 .
  • the unthreaded crossbar 20 is inserted through the latter until it abuts the blind hole.
  • the crossbar 20 is shorter than the outer width of the outer frame 14.
  • a sealing plug 50 is screwed into a threaded section of the stepped bore.
