Definitions

  • the present invention relates to a lift apparatus for an invalid, which is employed for lifting an invalid such as a sick person, a physically handicapped person or a bed-ridden old person for nursing him.
  • Japanese Patent Laying-Open No. 2-215462 (1990) proposes an improved bed apparatus.
  • this bed apparatus is rendered employable in a six- or four-and-a half-mat room, with provision of a lift apparatus which can lift up or lay down an invalid from or on the bed body, or move him to a bedside.
  • the pair of uprights are movable between positions within and out of the cross-directional dimension of the bed apparatus.
  • the side bars are vertically movable along the uprights and stoppable on the moved positions wherever the uprights are located. Consequently, the side bars can be located in arbitrary positions in the range of spaces above and beside the bed body.
  • the side bars When the side bars are employed for supporting the body of an invalid, therefore, the invalid who lies on the bed body can be lifted up from the bed body or moved to a bedside, and vice versa.
  • the bed sheet can be promptly exchanged, or the invalid can be readily bathed or seated on a wheelchair or a chamber pot.
  • An object of the present invention is to provide a lift apparatus for an invalid, which can be assembled independently of a bed and can be mounted on a vertically movable bed.
  • the inventive lift apparatus for an invalid comprises a guide rail which is detachably mounted on a bed on one longitudinal end thereof to extend widthwise along the bed, a movable body which is guided to be movable along the guide rail, and lift means which is mounted on the movable body.
  • the lift means includes an upright which is fixed to the movable body on a side portion to extend in the vertical direction, and an arm member having a first end which is coupled to an upper end portion of the upright and a second end serving as a working end.
  • the aforementioned guide rail is mounted on a vertically movable part of a bed, and the movable body is vertically slidably mounted on the upright.
  • the lift apparatus for an invalid may comprise no elements, such as the side bars included in the lift apparatus which is assembled with the aforementioned conventional bed apparatus, having lengths corresponding to the longitudinal dimension of the bed.
  • the lift apparatus for an invalid itself is miniaturized, and can be readily handled.
  • the guide rail can be mounted through a relatively heavy bed, whereby the same can be brought into a strongly fixed state with no requirement for a specific member for mounting the guide rail.
  • the number of components which are required for the lift apparatus for an invalid can be reduced.
  • the upright of the lift means itself is not vertically moved but enables cross-directional movement along the guide rail upon vertical movement of the movable part of the bed comprising the vertically movable mechanism.
  • the apparatus further comprises another guide rail mounted on a fixed part of the bed vertically movably supporting the movable part and another movable body guided to be movable along the fixed guide rail.
  • the lift means is supported not only by the guide rail but by the floor face through the wheel which is provided on the lower end portion of the upright of the lift means, whereby stability is further improved.
  • the arm member is driven by the actuator to be rotated about the upper end portion of the lift means, whereby the height of the forward end of the arm member can be freely changed.
  • This arm member is mounted to be also rotatable about the axis of the upright.
  • the working end of the arm member can be made to extend to a position sufficiently separated from a side portion of the bed by rotating the arm member about the axis of the upright with no extension of the upright itself beyond the cross-directional range of the bed. Consequently, the lift apparatus can softly move the invalid over a wide range, in order to nurse him.
  • the lift apparatus 1 comprises a guide rail 2.
