(57) Abstract:Usage: the invention relates to devices for moving loads. The inventive device includes a handle 1, 2 fingers, cheeks 3 and the grip 4 of the rope. The fingers 2 are connected with the cheeks 3, located in the same plane with the formation of a gap between them. In operation, the lever is rotated and the rope wound on the fingers. 3 Il. The invention relates to devices for moving loads.Known tal containing the lever, a drum for winding and clutch reverse (US, patent, 4235420, 254-218, 1981). The disadvantage of this device is its complicated structure.The closest in technical essence is a device for tensioning belts and ropes (US, patent, 4337555, B 66 D 3/02, 1982).The device comprises a lever, the free end of which a hook for gripping the rope, and the two cheeks, installed in parallel planes at a distance from each other of at least two diameters of the used cable. In the cheeks there are two holes for the shafts of the rollers that the rope goes around, and one of the holes made oblong. During operation, the first rope around one roller, which is rigidly fixed Bo the roller, clutching him the rope. After that, the rope is released and the operation is repeated. The device can be used to move cargo.A disadvantage of the known device is the complexity of the device and its operation.The technical result is to simplify both the structure of the device and its operation.This is achieved by the fact that in the known lifting device containing arm and cheek, United with elements for winding them rope, cheeks are located in one plane at a distance from each other along the axis of the lever with the formation of cracks, and elements for winding rope is made in the form of two fingers, the ends connected with the cheeks.In Fig. 1 shows a lifting device, a General view of Fig. 2 is a side view, and Fig. 3 sequence of operation of the device.The device includes a handle 1, 2 fingers, cheeks 3 and the grip 4 of the rope. Plate lever 1 and cheeks 3 are rigidly interconnected by means of two fingers 2. Cheeks 3 are located in the same plane and between them there is a gap. Plate lever 1, the cheeks 3 and 2 fingers form a drum to accommodate the rope. Capture 4 of the rope is made in the form of a hook or bracket, with space for the Zats liveout the device on the rope, using a crack between the cheeks 3, so that the rope was between 2 fingers (original position). Rotate the device in any direction to align its longitudinal axis with rope (the initial position And the cycle of winding of the rope on one turn). Then wound the rope on toes 2 by the action of the lever 1. One full rotation of the lever replace four half, which is carried out in strict sequence:
1st half-turn around the longitudinal axis of the device in any direction to position B.2nd half-turn around the transverse axis of the device from its original position Century.3rd half-turn around the longitudinal axis of the device, uncoiling the rope, twisted in the first half in position,4th half-turn around the transverse axis of the device in the initial position And through the source.Use 4 half of the device around mutually perpendicular axes instead of one full rotation around one axis significantly reduces the space required for movement of the lever and eliminates the need to step over the rope together with the lever.When translating device from the initial position vymatyvayutsya fingers 2, cheeks 3 limit the displacement of the rope along the fingers. While the required force at the end of the lever as many times less than the tension force of the rope, how many times the length of the lever is larger than the distance between the branches of the rope coming out of the drum. This distance is greatest at the position of the lever perpendicular to the rope, and depends on the placement of the fingers. Moving the fingers in the holes in the lever, you can choose the best for a particular cargo traction characteristic of a device, a combination of efforts on the lever and the step of moving cargo.The grip 2 is used to hook lever 1 for tight rope in order to preserve the rope taut. Capture it is recommended to use when turning the device around the rope (from position to position and from the position C To position D); coups geared lever safer.Because the device contains no moving parts, has high efficiency Lifting device containing arm and cheek, United with elements for winding them rope, characterized in that the cheeks are located in one plane at a distance from each other along the axis of the lever with the formation of cracks, and elements for winding rope is made in

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.
