Definitions

  • the subject of the present invention is a stretcher trolley with a layer plan which can be adjusted in height.
  • stretcher trolleys comprising a plate on which the person to be transported is stretched and which is mounted on a base provided with wheels making it possible to move said stretcher on the ground.
  • it is very important to adapt the height of the diaper plane relative to another plane on which the stretcher must be moved and in particular the floor of an ambulance.
  • each leg of the base is connected to the frame by a link articulated respectively on the frame 1 and on the leg, said link being connected to means for adjusting the height of the layer tray and said leg being connected to a means of holding and tilting the plate.
  • the device also includes a means for adjusting the inclination of the diaper tray to place the person in a determined position.
  • FIGS 1 to 4 there is shown an embodiment of a stretcher trolley according to the invention which comprises a frame 1 on which is fixed a layer tray 2 intended to receive an elongated person.
  • the frame 1 consists of two beams 3, 3a interconnected by crosspieces 4, 5 made of boxes intended to receive part of the mechanism. Handles 6 are provided at the ends of the side members for guiding the stretcher. On the frame 1 are mounted in an articulated manner two pairs of legs 7, 7a interconnected by a crosspiece 15, 15a and which rest on the ground by means of wheels 8 allowing the movement of the stretcher trolley.
  • each leg 7, 7a is connected to the frame 1 by connecting rods 11 articulated respectively around an axis 12 on the leg and around a shaft 13 pivotally mounted in bearings 14 fixed on the side members 3, 3a of the frame.
  • a fork 16 On the shaft 13 of articulation of each link 11 on the longitudinal members is fixed a fork 16 extending inside the longitudinal members 3, 3a and whose branches are engaged in two notches 17, 17a provided on both sides another of a transmission bar 18, 18a ( Figures 1, 2) slidably mounted in each beam 3, 3a.
  • the transmission bars 18, 18a each have two notches 19, 19a in which are engaged the two branches of a fork 20 fixed to each end of a shaft 21 rotatably mounted in the cross 5 of frame 1 ( Figures 1, 2 and 5).
  • a yoke 22 between the branches of which is pivotally mounted a nut 23 in which is engaged a threaded rod 24 rotatably mounted in a bearing 25 between two thrust washers 26, 26a, said bearing being articulated between two flanges 27, 27a fixed under the cross-member 5.
  • the threaded rod 2 is provided with a crank 28 allowing the threaded rod 24 to rotate and act on the nut 23.
  • the device comprises a bar 29 which is articulated at one of its ends around an axis 30 mounted in a yoke 31 fixed on the crosspiece 15 connecting each pair of legs 7, 7a ( Figures 3, 4 and 5).
  • the bar 29 is articulated around an axis 32 integral with a ball joint 33 mounted in a corresponding housing of one of the branches of a bracket 34, the other branch of which carries an axis 35 rotatably mounted in a bearing 36 fixed in the crosspiece 4 and 5.
  • the axis 35 is integral in rotation with a lifter 37 one end of which is articulated on the rod, a gas shock absorber 38 and the other end of which is articulated on the rod of a shock absorber 39, the shock absorbers 38 and 39 being fixed by an articulation on the cross-member 5.
  • One of the shock absorbers 38 is controlled by a means making it possible to cancel and restore the elastic effect of the gas in order to move the piston to modify the inclination of the legs 7, 7a relative to the frame and then to ensure the maintenance in position of the legs.
  • a stop member 41 constituted by a U-shaped bar capable of coming to bear against the legs 7 when folded.
  • the device according to the invention operates in the following manner.
  • the diaper tray being at a determined height, it may be necessary to bring it to another level in order in particular to load the stretcher in an ambulance.
  • action is taken on the crank 28 in order to rotate the threaded rod 24 (FIG. 5) and to move the nut 23 longitudinally relative to the screw.
  • the nut 23 being articulated in the yoke 22, it rotates the shaft 21 pivotally mounted in bearings of the cross-member 5.
  • the forks 20 integral with the shaft 21 are also driven in rotation and act by the notches 19, 19a on the bars 18, 18a which slide longitudinally in the longitudinal members 3, 3a.
  • the legs 7, 7a can be folded completely against the frame 1.
