  • Said device is connected to chains, straps, wires or similar 17, which are arranged to move within the sections 3, 3 ' , 6, 6 " , and attached to supporting members 18 embraced by the sections 3, 3 ' , 6, 6 ' , which extend through slots 19, 19 ' taken up in the sections 3, 3 ' , 6, 6 ' .
  • the load supporting member 1 may be detachably connected to the support members 18 within the sections 2, 2 ' , but also other types of attachment can obviously be used.
  • chains are used as means to transfer the movement of the winch or transmission device 10 to the load supporting member 1, attached at one end portion against the supporting members 18. The part of the chains 17 that will be released during a lifting operation falls down into a chain storage means 20.
  • the winch or transmission device is locked by means of the previously mentioned locking means.
  • the object 21 to be transported can thereafter easily be slided out from the vehicle and be located on the load supporting member 1, whereafter the object 21 preferably is locked in the position taken up by means of the clamping straps 16, 16 ' .
  • Transport from this initial position can thereafter be carried out in a number of ways, adapted to actual road of transport.
  • the l fting and transporting apparatus can be used as a conventional transport trolley, in which case the winch or transmission device 10 first is influenced in order to locate the load supporting member 1 immediately adjacent to the frameshaped support member 4 (Figs. 3 and 4).
  • the person performing the transport grips the running cords 14, having free end portions attached to gripping means 22, and by a pulling movement the lower support structure is lifted and- telescopically joined to the upper support structure, whereafter the lever 13 is influenced again, thereby influencing the locking means 11 and locking the first and the second support structure together.
  • This operation is more fully shown in Fig. 6.
  • the running cords 14 are arranged to pass through an annular member 23, attached to a spring 24 extending within a protective tubular member 25 (Fig. 9).
  • the running cords 14 are hereby - retracted to a position surrounded by the tubular member 25 as soon as the person performing the transport releases the gripping means 22.
  • the lever 13 is influenced again to release the locking means 11, whereby the first and lower support structure is moved down to a contact position against the ground surface, whereafter the lever 13 again is influenced in order to lock together the first and the second support structure.
  • the person performing the transport can thereafter move away from the lifting and transporting apparatus, which, due to the support against the ground surface from the support member 4, remains safely in the position taken up.
  • the load supporting member 1 is moved to a position adjacent to the supporting member 4, whereafter the lever 13 can be influenced in order to release the locking between the first and the second support structure, whereafter same are slided together.
  • the load imposed by the object 21 supported by the load supporting member 1 does not cause any downwardly directed force, and that only the weight of the upper and second support structure should be moved in direction downwards.
  • the corresponding condition applies with regard to an extension of the lifting and transporting apparatus in direction upwards, when same is performed with the object 21 located in the position shown in Fig. 3, provided that the winch or transmission device 10 is not locked.
  • the lifting and transporting apparatus may also be moved by two persons, carrying same in a fashion similar to a stretcher, as shown in Fig. 7.
  • the lifting and transporting apparatus has substantial advantages, particularly when transporting heavy and/or bulky objects, and when such transports are carried out by one person only. Since same is carried without any restricting carrying straps, the carrying person can also easily release himself from same, e.g. when falling in a staircase. Also from ergonomical point of view, there are substantial advantages in relation to previously known transport devices, since previously necessary lifting operations are substantially avoided, and since transfer either can be carried out with the apparatus used as a conventional transport trolley, or either carried on the back, with the load distributed over back as well as shoulders.
  • the load supporting member 1 pivotable between a substantially perpendicular position in relation to the sections 3, 3 ' , 6, 6 ' , and a position in which the load supporting, member 1 is arranged extending in a substantially parallel! relationship adjacent to the sections 3, 3 ' , 6, 6 ' .
  • the load supporting member 1 be arranged in the position adjacent to the sections 3, 3 ' , 6, 6 ' when the lifting and transporting apparatus is not being used, e.g. when transported in a vehicle, and the space occupied by the lifting and transporting apparatus is thereby reduced considerably.
  • the shape ' of the supporting members can thus be varied in order to adjust to existing transport needs, utilized lock members and lock means can be replaced by other known types, and the method to accompl sh displacement of the Toad supporting member 1 can also be varied, e.g. by ropes, wires, straps, chains or racks used to transfer a movement.
