Definitions

  • Striker ABSTRACT A stretcher support arrangement for ambulances in which a stretcher support frame is mounted movable between a substantially horizontal rest position located within the ambulance and an extended position partly outwardly withdrawn therefrom and with the outwardly extending end downwardly tilted on frame means fixed to the floor of the ambulance. Links guided in guide rails are connected to the stretcher support frame to move the latter automatically to its tilted position when the' support frame is pulled towards its extended position.
  • the present invention relates to a stretcher support arrangement, especially for ambulances, with a stretcher support frame which can be moved from a substantially horizontal rest position in longitudinal direction to an extended inclined position with the outwardly extending end moved in downward direction, and back from the extended, inclined to the horizontal rest position.
  • the inclined or tilted position of the stretcher support frame greatly facilitates to place a stretcher on this frame and to remove a stretcher therefrom.
  • Stretcher support arrangement for ambulances are already known in which the stretcher support frame is tiltable about an axis extending transverse to the longitudinal direction of the frame permitting to place the head end of the frame into a lower position, and in which the head end of the frame is appropriately guided.
  • This known stretcher support arrangement does not permit the stretcher support frame to .tilt in its outwardly extended position in such a manner that the outer end of the frame is moved downwardly.
  • the stretcher support arrangement mainly comprises support means adapted to be mounted in fixed position in an ambulance, an elongated support frame adapted to support a stretcher thereon superimposed on the support means, means guiding the support frame movable in longitudinal direction between a substantially horizontal rest position coextensive with the support means and an extended position extending with an end portion thereof beyond the support means.
  • support link means pivotally conneeted at one end to the support frame at a region of the end of the latter which is opposite said one end por* tion, and longitudinally extending guide rail means for guiding the support link means and for releasing the one end thereof from the guide means when the support frame is in its extended position so that the support link means may be tilted about the other end thereof in upward direction to thereby tilt the support frame correspondingly.
  • the support link means therefore serve to guide the support frame during its movement in longitudinal direction and to tilt the latter in its extended position.
  • Abutments means are preferably provided in the region of that end of the guide means which face the one end portion of the support frame and the other end of the guide link means abuts against this abutment means during movement of the support frame from the rest towards the extended position.
  • the guide rail means and the abutment means are constructed and arranged in such a manner so that a force acting in longitudinal direction of the support frame for moving the latter to the extended position will first cause movement of the support frame in this direction while the support link means are guided in the guide means and, after the other end of the support link means engages the abutment means, upward tilting of the support link means and thereby a corresponding tilting of the support frame.
  • the support link means preferably comprises a pair of guide members respectively arranged on opposite ends of the support link means and the guide rail means has guide faces including an upper guide face for guiding the support members substantially along the length of the guide rail means.
  • the upper guide face is provided with an opening intermediate the opposite ends of the guild rail means permitting movement of the guide member at said one end of the support link means upwardly through this opening and upward tilting of the support link means about the other guide member.
  • the guide rail means preferably has a downwardly inclined end portion facing said one end portion of the support frame so that during movement of the support frame towards its extended position the support frame will assume an already partly inclined position so that only a limited further inclination will be necessary at the end of the movement of the support frame towards its extended position.
  • FIG. 1 is a perspective view of the stretcher support arrangement according to the present invention and showing the stretcher support frame in its rest position;
  • FIG. 2 is a perspective view drawn to a slightly smaller scale in which the stretcher support frame is shown in its extended and tilted position;
