JPS586873Y2 - Lifting hanging device - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a lifting and hanging device.

This will be explained with reference to the drawings. Reference numeral 1 denotes a movable pulley, which is rotatably fixed to the bottom of a small upright pipe 2.

3 is the large pipe 1. Insert the small pipe 2 into this.

Reference numeral 4 denotes a fixing part protruding from the outer upper part of the large pipe 3, and 6 a bearing protruding from the outer upper part of the large pipe 3 (on the opposite side of the fixing part 4), to which the fixed pulley 7 is rotatably fixed.

5 is a wire rope, one end of which is connected to a connecting hole 9 of a fixed part 4 on the outside upper part of the large pipe 3, and the other end is connected to a winch 8 via a movable pulley 1 and a fixed pulley 7.

10 is a handle connected to the winch 8, 11.11 is a support frame and is a pipe, and 12 is a support of an appropriate shape fixed to the upper end of the small pipe 2, which pushes up the object.

11' is a supporting frame that is perpendicular to the supporting frames 11, 11; 13 is a U-shaped receiving part fixed on the supporting frames 11, 11, and is fixed to the lower end of the large pipe 3 so as to enclose it; A support shaft connecting the bearing part 13 and the large pipe 3, 15.15 is the large pipe 3
A through hole is drilled in the side wall of the small pipe 2, and a through hole is also drilled in the small pipe 2 to match these holes, and a support rod (not shown) is inserted through each of the through holes of the small pipe 2 and the large pipe 3. A small pipe 2 and a large pipe 3 are integrated.

The small pipe 2 and large pipe 3 are shown as square pipes in the drawing, but
A round tube may also be used.

As shown in FIG. 2, the small pipe 2 has two pipe members connected by a connecting rod 16, 16 with a gap 1B between them, a bearing 17 fixed to the lower end, and a movable pulley 1 attached to this. Fix it.

Note that the small pipe 2 can be made into a round pipe by making the cross-sectional shape of this pipe member semicircular and connecting them back to back.

Therefore, since a gap 18 is created between the two pipes, the wire rope 5 fits into this gap 18 during operation as shown in FIG. 1, making the operation easier.

A notch 19 is formed in the upper side wall of the fixing part 4 at the upper end of the large pipe 3, and the wire rope 5 connected to the connecting hole 9 of the fixing part 4 passes through this notch 19.

To explain the effects of the present invention, in Fig. 1, the handle 1
When the winch 8 is rotated by rotating the winch 8 in the direction of the arrow, the wire rope 5 moves in the direction of the arrow, the small pipe 2 rises, and objects connected to or loaded thereon can be lifted.
Conversely, by rotating the handle 10, the object can be suspended.

Since the ratio of the amount of winding of the winch 8 to the amount of movement of the movable pulley is 2:1, heavy objects can be lifted and suspended with a small force.

The device of this invention is compact and highly stable in that the large pipe 3 and the small pipe 2 are slidably fitted together, but the wire rope 5 operates while being accommodated in the gap 18 between the small pipes 20 and 2. There is no problem with the vertical movement of the

Furthermore, in order to topple the large pipe 3, it is sufficient to rotate the large pipe 3 to the right around the support shaft 14, and also pull out the small pipe 2 from the large pipe 3, and also pull down the wire rope 3.
It is convenient to remove and disassemble for storage and transportation.

This invention has an extremely wide range of uses, including not only lifting and hanging objects, but also work at heights, building scaffolding, installing outside lights, etc.
