Definitions

  • the present invention relates to a safety device for an apparatus provided for lifting and lowering loads and comprising at least one column, an arm attached to this column and pneumatic, hydraulic or motor means for moving said arm up and downwards.
  • the arm In apparatus or devices of the most common type for lifting and lowering patients, the arm is hingedly connected to the hereabove mentioned column. Lifting and moving the arm downwards is realized, in many cases, by a motor although hydraulic or pneumatic drives may also be used.
  • the arm is moved upwards and downwards by a rod which is itself partially shaped as a spindle rod.
  • a rod which is itself partially shaped as a spindle rod.
  • An object of the present invention is now to provide a safety device which solves this problem and which offers a large safety in those cases wherein a drive motor or any other drive means of such an arm does not react in time to a received command or when the command is simply not given so that the arm continues to move downwards with a large force.
  • the intention is therefore to provide a device of the hereabove described type which can be stopped when the arm of the apparatus meets an obstacle during its downward movement.
  • said means act upon a rod which slides telescopically in a hollow tube or upon a hollow rod which slides around a loose rod in order to lift said arm and to lower it in such a manner that when said arm is held back either directly or indirectly by an obstacle, the rod and the hollow tube, on the one hand, and the hollow rod and the loose rod, on the other hand, can slide with respect to one another so as to prevent a further downward movement of the arm when said arm is held back for example by an operator.
  • the safety device shown in these different figures belongs to an apparatus for lifting and putting down loads.
  • Such an apparatus consists amongst others of a column 1 with a hinged arm 2. This arm is lifted according to the principle of a lever of the third order. Lifting the arm 2 is realized by making use of an electric motor 3 which drives in the cylinder4 a jack rod or spindle which exerts the necessary pressure onto the rod 5 to lift the arm 2.
  • the rod 5 is pushed out of the cylinder 4 and slides into a hollow tube 6 which cooperates tel- escopicallywith this rod.
  • the tube 6 is hingedly connected in 7 to the arm 2.
  • the rod 5 is replaced by a hollow rod 8 (figures 5 and 6), while the hollow tube 6 from the embodiment according to figures 1 to 4 is replaced by a loose rod 9 having a cylindrically shaped abutment 9', the uppermost portion of the hollow rod 8 can push against during the upward movement of the arm 2.
  • FIG 7 there is shown a variant wherein two columns 10 are present along which an arm 11 can be displaced up and downwards.
  • the components which enable to up and downward movement of the arm 11 are here of the type according to figures 5 and 6 wherein a loose rod 9 can be displaced in a hollow rod 8. Also in this case an intervention is possible to prevent the arm 11 from moving further downwards against the will of the operator since upon a further continued rotation of the electric motor 3, the hollow rod 8 will be pulled further downwards and will further displace along the loose rod 9 so that when the arm 11 is hold back manually, this can be realized by the intervention of one or two operators.
