Definitions

  • the invention relates to a stretcher comprising a frame having at least two upper guides situated in parallel on the front and rear sides thereof, respectively, for a belt portion movable over said guides for support- .ing a human body.
  • the frame also has at least two parallel lower guides situated on the front and rear sides,
  • a driving mechanism is provided for rotating one of the lower or upper guides.
  • the posture of the injuredperson need not be changed so that the risk of additional injuries, such as complicating spinal injuries or fractures of other parts of the human body, is minimized.
  • the stretcher according to the invention is characterized in that the two belt portions are part of one finite belt which is coupled at one end to a first belt drum and at its other end is coupled to a second belt drum.
  • the belt is guided from the first belt drumover the two upper guides and then over the two lower guides, in such manner that the belt portions located between the two upperand the two lower guides move in the same direction relative to the frame.
  • a driving mechanism is provided for rotating at least one of the belt drums on which the belt is wound.
  • FIGS. 1 2 and 3 are three diagrammatic crosssectional views of an embodiment of a stretcher according to the invention.
  • FIG. 4 is a view similar to FIG. 1 showing another embodiment of the invention.
  • FIGS. 5 and 6 are schematic representations of the embodiments shown in FIGS. 1 and 4 respectively showing the path of travel of the finite belt.
  • the stretcher comprises a belt 1 which is coupled at its end to belt drums 2 and 3 comprising shafts 4 and 5. Between the belt drums 2 and 3, the belt 1 is guided over guide rollers 6 in such a manner that a belt portion 7 supporting a human body and a belt portion 8 for contacting the ground is formed. Upon movement of the belt said two belt portions will move in the same direction relative to the frame lll.
  • the belt portion 7 slopes downwardly to the front end, that is to say in the direction of the right-hand end of the stretcher shown in FIG. 1.
  • a backing plate 9 is disposed below the belt portion 7, said plate being secured at its edges to the sheet steel side frames 10 and 11 in which the shafts 12 of the guide rollers 6 are also incorporated. The backing plate 9 prevents sagging of the belt upon being loaded.
  • On the rear side of the stretcher two plates 13 secured to the side frames 10 and 11 constitute a support for the driving mechanism.
  • a shaft 15 is incorporated in the upper part of the plates 13.
  • the shaft 15 has a handle 16 (FIG. 3).
  • a chain wheel 17 is secured to the shaft 15 while on the said shaft a pair of parallel extending arms 18 and 19 are also rotatably secured.
  • the arms 18 and 19 support a shaft 20 on which a chain wheel 21 and a toothed wheel 22 are fixed.
  • a chain 23 (FIG. 1) connects the chain wheels 17 and 21.
  • the toothed wheel 22 in its mid-position is just in mesh with the two wheels 24 and 25 which are secured to the shafts 4 and 5 of the belt drums 2 and 3.
  • the belt 1 is then wound on belt drum 3 and unwound from drum 2. If desirable, this can be done to move a person off the stretcher. As a result of the movement of the belt portion 8, the stretcher, viewed from the situation shown in FIG. 1, will then move to the left while the belt portion supporting the human body will move to the right. In order to prevent the non-driven drum from starting to rotate in an un- In this manner a stretcher can be moved under the I body of the injured person or be removed from below his body.
  • the stretcher furthermore comprises lifting handles 26 and transverse traps 27 (FIG. 2) are provided at intervals along the stretcher.
  • the driving mechanism with chain and chain wheels is shown by way of example. It will be obvious that other driving mechanisms for the belt drums are possible in which either only that belt drum is driven on which the belt is wound, or in which both drums are driven in opposite directions. In the last-mentioned case it should be ensured that a compensation be present for the variation of the belt drum diameter upon winding and unwinding the belt.
  • a driving mechanism may be used, for example, a worm which cooperates with worm wheels on the shafts or the belt drums.
  • the belt runs from belt drum 2 first over the upper guides from the left to the right and then over the lower guide also from the left to the right.
  • FIG. 4 diagrammatically shows how the belt 1 can also run from belt drum 2 first to the front guide and then from the right to the left over the upper guide as a belt portion supporting a human body to the rear side of the stretcher.
  • the belt then runs between the belt drums 2 and 3 again to the front of the stretcher to run again as belt portion 8 from the right to the left over the guides 6 to belt drum 3.
  • the driving etc. is not shown but this may be constructed in various manners. What matters, however, is that upon moving the belt and this applies both to the construction shown in FIG. 1 and to the construction shown in FIG. 4 the belt portions 7 and 8 move in the same direction and opposite to the movement of the frame.
  • a stretcher comprising a frame having at least two parallel upper guides located on the front and rear sides thereof, respectively, a first belt portion movably carried over said guides for supporting thereon a human body, at least two parallel lower guides carried by said frame and located on the front and rear sides, respectively, a second belt portion movably carried over said lower guides and arranged for contacting the ground, said first and second belt portions moving in the same direction relative to the frame when in operation, said first and second beltportions forming part of the finite belt coupled at one end thereof to a first belt drum and at its other end to a second belt drum, said finite belt being guided from the first belt drum over the two upper guides and then over the two lower guides so that said first and second belt portions between the two upper and the two lower guides move in the same direction relative to the frame, and a driving mechanism carried on said frame for rotating at least that belt drum onto which the belt is wound.
  • a stretcher for supporting thereon injured persons comprised a pair of side frames, first and second belt drums rotatably mounted between said frames, a finite belt extending between and carried by said drums, upper guide means mounted between said side frames for guiding a portion of said belt movably along the upper part of said frame so as to expose said portion of said belt for support of a human body, lower guide means mounted between said side frames for guiding a portion of said belt along the lower part of said frame so as to expose said portion thereof for contact with the ground, intermediate guide means mounted between said side frames for guiding said belt between said upper and lower guide means, and means for causing rotation of at least one of said belt drums for winding said belt thereabout, whereby said belt is guided from said first belt drum over said upper guide means and then via said intermediate guide means over said lower guide means and onto said second belt drum so that when said belt drum is caused to rotate said belt portion guided over said upper guide means for support of a human body and said belt portion guided over said lower guide means for contact with the ground will be moved in the same
  • said upperguide means comprises at least two guide rollers arranged in parallel relationship to each other, one of said rollers being located at the forward end of said frame and the other being located at the rear end of said frame, and wherein said lower guide means comprises at least a pair of rollers being parallel to each other and located at the forward and rear ends respectively of said frame.
  • the stretcher according to claim 4 further comprising a backing plate secured between said side frames below the portion of said belt being guided over said upper guide means for supporting a human body carried by said belt portion.
  • a stretcher for automatically lifting patients comprising a frame, a pair of rotatably mounted drums carried by said frame, a belt of finite length having each of its ends attached to one of said drums so as to be carried therebetween, a pair of upper guide rollers located in parallel relationship on the forward and rear ends of said frame for guiding a portion of said belt over said rollers so as to make said portion available for supporting a person, said upper guide roller at the front end of said frame being in a lower position relative to the ground than the upper guide roller at the rear end of said frame so that said belt portion travelling over said upper guide rollers extends in a forward sloping downward direction, a plurality of lower guide rollers located along the lower portion of said frame for guiding thereabout a portion of said belt which is movable over said rollers and arranged for contact with the ground so that as said belt moves over said lower rollers said frame will be propelled along the ground in an opposite direction to the direction in which said belt is travelling over said rollers, guide means for guiding said belt between said upper
