【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. In FIG. 1 and FIG. 2, a tripod-shaped support leg 1 has legs 3 arranged in three outer directions of a central shaft 2, and an upper portion of the central shaft 2 is provided with a lever 5 through a universal joint 4. The center is provided. Reference numeral 6 is a reinforcing rod that connects the lower portion of the central shaft 2 and the leg portion 3. The central shaft 2, the lever 5, and the reinforcing rod 6 are made of aluminum pipe. A hook-shaped connecting portion 8 for connecting one end of a linear body 7 such as a wire rope, which is a hanging tool, is fixed to the tip of the lever 5. The other end of the wire rope 7 is wound around a rock A which is a heavy object.

As shown in FIG. 3, the universal joint 4 is provided with a bearing 9 provided on an upper portion of the central shaft 2 and having an axis B in a vertical direction, and mounted on the bearing 9 so as to be horizontally rotatable. It is composed of a fixture 10 for supporting the lever 5 so as to be rotatable in the vertical direction. The bearing 9 is fixed to the upper end of the center shaft 2 with its axis B oriented vertically, and a fixture rotating plate 11 with the axis B as the center of rotation is rotatably attached to the upper surface of this thrust type bearing 9. It is provided. Then, the bolt 12 penetrating the fixture rotating plate 11 is screwed into the fixing member 13 fixed to the central shaft 2 to prevent the fixture rotating plate 11 from coming off. Furthermore, the fixture 10 has a pair of left and right first projecting pieces 14 projecting upward from the fixture rotating plate 11, and a short pipe through which the lever 5 penetrates above the projecting pieces 14. A fixture-like main body 15 is provided, and a second projecting piece 16 projects downward from the lower part of the fixture body 15, and the first projecting piece 14 and the second projecting piece 16 are provided. 16 and 16 are rotatably connected to each other by a mounting shaft 17 with the axis C oriented horizontally. Further, the fixture main body 15 is provided with a fixture 18 such as a bolt for fixing the lever 5.

Next, the function and effect of the above configuration will be described. First, a linear body 7 such as a wire rope is wound around the rock A, and the upper end of the linear body 7 is connected to the connecting portion 8 at the tip of the lever 5. At this time, the length E between the attachment body 15 and the proximal end of the lever 5 held by the operator should be larger than the length D between the connecting portion 8 and the attachment body 15 (D <E). Then, the lever 5 is slid on the fixture body 15 and the fixture 18 is tightened and fixed. When the worker F pushes down the lever 5, the lever 5 rotates about the axis C as a center of rotation and the rock A is lifted. At the same time, when the worker F pushes the lever 5 in either the left or right direction, the lever 5 rotates around the axis B as the center of rotation and the rock A moves. After moving the rock A in this way, it is lowered to the predetermined place indicated by the alternate long and short dash line.

When moving the rock A again, after attaching the linear body 7 such as a wire rope to the rock A and moving the supporting leg 1 to the position shown by the alternate long and short dash line, perform the same work as above. .

After the work is completed, the fixing tool 18 is operated to loosen the lever 5 so that the supporting leg 1 and the lever 5 are disassembled.

As described above, in the embodiment of the present invention, the lever principle is utilized by providing the substantial center of the lever 5 on the upper part of the supporting leg 1 through the universal joint 4 according to claim 1. Then, the rock A as a heavy object can be easily lifted, and the rock A can be moved to a desired position by the universal joint 4.

In addition, in the embodiment of the present invention, according to claim 2, the supporting leg 1 is formed of a tripod by the leg portion 3, so that it has excellent stability, and the lever 5 slides on the universal joint 4. Since it is movably and detachably fixed, the fulcrum and action point of the lever 5 and the lengths D and E of the fulcrum and the force point can be adjusted, and the fulcrum 1 and the lever 5 can be easily disassembled. You can also do it. Further, since the hanging tool connection portion 8 is provided on the distal end side of the lever 5, it is possible to easily connect the linear object 7 such as a wire rope, which is the hanging tool, to the lever 5. Moreover, since the supporting leg 1 and the lever 5 are formed of pipes, they are lightweight and can be easily transported.

Further, in the embodiment of the present invention, according to claim 3, a universal joint 4 is provided on the upper portion of the central shaft 2 of the supporting leg 1 and a bearing 9 provided with an axis B in the longitudinal direction, and this bearing 9 A fixture 10 that is rotatably mounted horizontally on the lever 5 and supports the lever 5 rotatably in the vertical direction; and the lever 5 that is provided integrally with the fixture 10 penetrates the lever 5 and By providing the fixture 18, horizontal rotation is possible by the bearing 9, while vertical movement is possible by the fixture 10, so that the lever 5 can be easily oriented in any direction. it can. Further, since the fixture body 15 through which the lever 5 penetrates is provided with the fixture 18, the lever 5 can be easily slid and fixed, and can be pulled out.

FIG. 4 shows a second embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

In the second embodiment, a plurality of connecting portions 21, 21A, 21B, 21C are provided on the upper surface of the lever 5 on the tip side in the axial direction of the lever 5, and further, the lever 5 is further provided. A guide groove 22 is vertically provided at the tip of 5.

A suspending tool 31 for lifting the lid H of the side groove G includes a pair of left and right substantially L-shaped holding bodies 33 which are crossed at substantially the center and are pivotally mounted by a shaft 32, and lower ends of these holding bodies 33. A linear member 34 such as a wire rope that connects to the upper end and connects the upper end to the connecting portions 21, ..., and the above-mentioned lid H provided at the lower ends of the pair of sandwiching bodies 33 and provided inward with respect to each other. And a hook portion 35 that can be locked. Incidentally, 36 is a handle.
