Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging device used for transportation, setup work, and the like.

Conventional hanging tools of this type have different methods depending on the item.
When suspending a rod-shaped or cylindrical article 2 as shown in the figure, a hanging tool 1 is used to suspend it from two points. On the other hand, when suspending a flat article 4 as shown in FIG. 2, a hanger 3 is used to hang it from three points.

In this way, since the hanging tools are replaced depending on the item, it not only takes a lot of time to replace the hanging tools, but it is also uneconomical because two types of hanging tools have to be prepared.

In view of the above, it is an object of the present invention to provide a hanging tool that can perform two-point hanging and three-point hanging with one device, in which a flat article can be lowered by 3 m9 at 3 points.
Of the three first to third hanging arms formed in a letter shape, by moving the first hanging arm by operating the handle, the other second hanging arm and third hanging arm can be rotated. They are hung in a straight line, and rod-shaped items can be suspended from two points via these hanging arms.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 3 and 4, reference numeral 5 designates a pair of discs 5a each having a long hole 9 in the center in the radial direction.

5b2, with their long holes 9 facing each other, and a plurality of setting reamer bolts 19 and three arm side reamer poles) 88
This is a main body that is integrally connected at a constant interval by ~8C. Reference numerals 6A to 6C indicate first to third hanging arms whose respective base end portions 6Aa to 6Ca slide with the respective side discs 5a and 5b while keeping minute gaps; A a 1 to 6Ca are polymerized as shown in FIG.
A bottle 7 fixed to l is inserted. Further, the base end 6Aa of the first hanging arm 6A is provided with a long hole 6Ab into which the arm reamer bolt 8a is inserted. Third hanging arm 6B, 6
C is arm side reamer pole) 8b.

They are each pivoted to 8C.

12Ifi is an operation mechanism for moving the first suspension arm 6A, and this operation mechanism 12 includes a stud 13 screwed and fixed to the base end 6Aa of the first suspension arm 6A, a nut 14 that engages with this stud 13, and a nut 14 that is engaged with this stud 13. The handle 15 attached to the nut 14, the nut 14 and the side discs 5a, 5b'ft:
It is composed of a pair of holders 16 that are connected to each other. One end of both holders 16 is pivotally connected to the disks 5a and 5b via a reamer bolt 17, and a protrusion 16a provided at the other end is locked to the collar 14a of the nut 14.

Next, the operation of this embodiment configured as described above will be explained.

When the handle 15 of the operating mechanism 12 is turned to rotate the nut 14, the first hanging arm 6A is moved to the left (in the direction of arrow X) via the stud 13 that engages with the nut 14. The leftward movement of the first hanging arm 6A is stopped when the left end of the elongated hole 6Ab touches the reamer bolt 88, as shown in FIG.

In this case, when the first hanging arm 6A moves to the left, the bottle 7 fixed to the arm 6A also moves to the left, so the second hanging arm 6B moves clockwise (arrow Y) via the bottle 7 to the third hanging arm 6A. Hanging arm 6c
are respectively rotated counterclockwise (arrow 2), and stopped in a straight line as shown by the third dashed line.

On the other hand, if the handle 15 is turned in the opposite direction to the above case, it is possible to cause abdominal pain.

By operating the handle 15 as described above, the hanging tool t changes from a Y-shaped three-point hanging state to a T-shaped two-point hanging state, and conversely from a two-point hanging state to a three-point hanging state. Each can be easily switched.

Figure 5 shows each hanging arm 6A to 6CK of a 3-point hanging hoist, electric chain CI7 2oA to 2oc'ft: attached respectively, and a flat article 21 suspended at three points by these electric chain blocks 20A to 20C. This shows the lowered state. Also, Fig. 6 shows the second hanging arm 6B and the third hanging arm 6.
c and rotated as described above to form a straight line, and an electric chain block 20B attached to each rising arm 6B, 60,
20C shows a state in which a rod-shaped item 22 is suspended at two points.

Hanging hands 23 that support each of the above cities CM6A to 6C
The difference in length between A to 23C is determined by interlocking the suspension arms 6A to 6C and by moving the hanging arms 6A to 6C in an interlocking manner, and by moving the hanging arms 6A to 6C in an interlocking manner, and by moving the hanging arms 6A to 6C in an interlocking manner, and by moving the hanging arms 6A to 6C in an interlocking manner.
By appropriately selecting the arrangement of the reamer bolts 7b and 8c, the length of the straight line connecting the center of the bottle 7 and the reamer bolt 8b or 8C, and the length of the straight line connecting the centers of both the reamer bolts 7b and 7c can be adjusted to 1/1/2.
The difference between 2 and 2 can be reduced to a level that does not pose a practical problem. Therefore, when the lifting tool is switched from a 3-point hanging state to a 2-point hanging state, the second hanging arm 6B and the third hanging arm 6c can be maintained almost horizontally, so that the lifting arm can be kept almost horizontally. 23A-23C and hanging arms 6A-6
It is possible to prevent excessive force from acting on the pins (not shown) connecting the terminal c and the terminal.

As explained above, according to the present invention, the three-point hanging state or the two-point hanging state can be changed to the three-point hanging state or the two-point hanging state at any time by operating the handle.
In addition, since it can be easily switched, there is no need to replace the lifting tool depending on the item, so work efficiency can be improved. Further, according to the present invention, one device can perform the functions of two devices, so there is an advantage that it is very economical.
