FIELD: medicine.
SUBSTANCE: invention relates to medical technology and devices for loading solid and quick (granular) loads. The device for lifting and stowing a load has flexible and rigid support structures. The rigid support structure is made from rigid bars in form of a rectangular frame. The frame has one of the smaller sides in form of an axis, on the entire length of which are threaded pipe-shaped rollers or fitted a solid pipe-shaped roller. The ends of the axis are pivotally connected to push-pull levers. The levers are independent of each other or joined by a common cross bar. The flexible support structure has an elongated rectangular shape and is made from a flexible inextensible material, and on another version, is made in form of a track chain from a set of pivotally joined track links, with a cylindrical roller which can rotate inside each track link. The lateral surface (rounded) of the said roller projects behind the track link on the outer surface (not in contact with the rigid support structure). The roller axis of the said rectangular frame is directed across the vector of the working path of the device. In the initial position, the flexible support structure is folded in half with alignment of the shorter lateral sides. The rectangular frame is rests on the roller axis at the bending point of the flexible support structure. The top edge of the flexible support structure can be attached to any fixed object.
EFFECT: reduction of physical effort required for loading and unloading from one surface to the other, as well as reduction of mechanical effect of the support structure on the transferred load.
