Definitions

  • the present invention relates to portable and folding objects such as a portable bridge, portable bed, or portable stretcher.
  • portable objects which are the subject of the present invention are of the type which include folding connecting elements such as spacers and folding frames, extending between two parallel sets of load-bearing rods and these connecting elements entail limitations as regards the way to fold such an object.
  • a folding stretcher is requested by people who walk on foot in places where there is no access to normal ambulance services, i.e. for exploratory expeditions in remote areas, for example mountaineering expeditions, hikers; combat infantry etc. In all these situations, there is usually a rescuer present who must carry the folding stretcher in addition to his personal equipment.
  • the folding stretcher should not only be made of a material as light as possible but must also be able to fold in a volume-as low as possible, so as not to interfere with the freedom of movement of the wearer.
  • the fabric and the folding support and bracing means impose limitations and constraints on the way of folding a stretcher and, consequently, known folding stretchers generally fold only twice, the first time by erasing the bracing and support elements so as to bring the two sets of support rods together and a second time by folding the two sets of rods in half, in order to reduce their size by half.
  • a stretcher folded in this way to a length of 1.05 meters and it is obvious that a stretcher folded of this dimension hinders the movements of the wearer. It is therefore an object of the present invention to provide a folding stretcher which can be folded into a compact state of reduced size.
  • the object of the present invention is to provide portable folding objects which can be folded into a compact folded form which is easy to carry and transport.
  • the invention relates to a folding frame comprising first and second sets of supporting rods connected to each other by folding connecting means, each of the first and second sets of rods comprising a central joint, a pair of internal rods each articulated on an edge of the central joint so as to allow the internal rods to be bent towards one another around a folding axis which extends in space in a direction normal to the longitudinal axis of the 'set of supporting rods, a pair of end rods each connected to the associated internal rod by a joint (peripheral joint) so as to be able to bend around a folding axis extending in space in one direction which makes an angle with the folding axis of the central joint; the folding axis of the peripheral seal of the first set of load-bearing rods extending in space essentially normally to the fold axis of the central seal while the fold axis of the second set of load-bearing rods extends into the space in a direction which makes an angle other than 90 ° with the folding axis
  • the invention also relates to a portable folding object provided with a folding frame as described.
  • a typical application of the invention is that of a portable stretcher comprising a folded frame as described and a canvas held by said first and second sets of load-bearing rods.
  • Another application of the invention is that of a portable bed provided with a folding frame as described, and yet another application of the invention being that of a portable bridge provided with a folding frame as described.
  • the frames according to the invention are made of light metal, such as aluminum for example.
  • the frame 'stretcher shown comprises a first rod set carrier 2 and a second set of carrier rods 3 connected by a pair of folding arquées4 spacers, each comprising a pair of bars 5 and a connecting part 6, each of the bars 5 being articulated by one end on a connecting piece 6 and by the other end on the set of associated carrying rods.
  • the framework 1 On its rear side, the framework 1 comprises four feet 7, two integral with the set of rods 2 and two integral with the assembly of rods 3.
  • the first set of rods 2 comprises a central joint 8 on which two internal rods 9 are articulated so as to allow each rod 9 to tilt 90 ° around an axis which extends in space in a normal direction to the longitudinal axis of the joint 8, so that it can come to occupy the positions represented in FIGS. 3 and 4.
  • the first set of rods further comprises a pair of end rods 10 each connected with the associated rod 9 by a peripheral seal 11, the connection between the seals 11 and each of the rods 9 and 10 being produced so as to allow the assembly 10, 11 to bend around a folding axis which extends in space according to a direction normal to that of the folding axis of the central joint 8, as shown in FIGS. 4 to 6, in order to reach the double folded position shown in FIG. 7.
  • the peripheral seals 11 are prevented from folding back by the canvas and the weight of the person carried.
  • a second set of supporting rods 3 comprises a central joint 13, a pair of internal rods 14 articulated on the central joint 13 in the same way as the rods 9 are articulated on the central joint 8, and a pair of end rods 15, each of which is articulated to the associated rod 14 by a peripheral seal 16 so as to allow the assembly 15, 16 to bend around a folding axis which extends in space in a direction which makes with the folding axis of the joint 13 at an angle other than 90 °. Consequently, each end rod 15 can tilt in a plane which intersects the plane of the unfolded framework. For this reason, the seals 16 are provided with a locking mechanism to prevent their collapse, as will be described below in more detail.
  • end rods 10 and 15 carry handles 17.
  • each of the assemblies 9, 10, 11 and 14, 15, 16 is tilted 90 ° around the pivots by which the internal rods 9 and 14 are articulated on the central joints 8.
  • the beginning of this phase folding is shown in broken lines in Figure 3 and the end of this phase is shown in solid lines in Figure 4.
  • the frame is in the form U-shaped, elements 5, 6, spacers 4 and feet 7 being positioned inside the U as shown.
  • the framework 1 is associated with a fabric which, in the unfolded state of FIG. 1, is located above the arched spacers 4 and this requires that the end rods 10 and 15 must all be folded on the same side of the fabric.
  • the canvas has not been shown in the drawings for clarity of the representation.
  • FIGS. 8 and 9 we see, on a larger scale, a seal 16 provided with a locking means for prevent unwanted bending of the bars 15 and 14 of the second set of support rods 3.
  • the seal 16 comprises a curved elastic locking device consisting of two annular members 19 held by a connecting piece 20.
  • Two plates 21 are mounted on the upper face of the seal 16 and each has a re-entrant edge retaining the extreme portions of the associated annular member 19. Near one of these ends, each plate 21 is made integral with the joint using a rivet 24.
  • Each of the plates 21 is pierced with a hole 22 which cooperates with a boss 23 integral with the associated rod 14 or 15.
