DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspended object, for example, a rectangular plate, which has a corner (in the sense that there is a portion protruding from a base, its tip may be rounded or rounded; the same applies hereinafter). The present invention relates to a hanging bracket capable of safely and labor-saving lifting the like.

[0002]

2. Description of the Related Art At sites where heavy iron plates and the like are handled, for example, at civil engineering sites, the ground is often incomplete and soft ground, which hinders entry of vehicles. For this reason, square iron plates called iron plates are laid on the runway. This spread iron plate has a heat of 22mm, length and width of 1500x3000m
m is often used, but such a laid iron plate weighs about 1 ton and its laying is very difficult.

[0003] The laying and clearing of the laying iron plate is performed by unloading from the vehicle or being loaded on the vehicle. In this case, the laying iron plate needs to be lifted. However, such a heavy and large-area laid iron plate is difficult to handle, and it is very difficult to lift it safely, labor-saving, and in a short time.

[0004] For this reason, a hoisting force used in a factory or the like is lifted by being sandwiched by a clipping tool which is converted into a gripping force, or a hole is made in a spread iron plate, and a wire or the like is passed through the hole. In addition, a spread iron plate is attracted and lifted by a magnet.

[0005]

However, the clipping device is slippery and lacks safety, while the clipping device requires a lot of trouble and the presence of the hole impairs the function as a rug. Sometimes. On the other hand, in each of these methods, the laid iron plate is lifted vertically (perpendicular to the ground), so that it must be turned sideways (parallel to the ground) in order to drop it on the ground or on a car. .

[0006] Therefore, there is a gap between the lifting position and the unloading position. To correct the gap and unload the vehicle, a skill for guiding is required. In addition, the burden of the work for guidance increases, and there is a fear that an accident may occur at this time. In addition, it is strongly affected by the wind and can shake and be dangerous.

[0007] In this respect, magnets have the advantage that the spread iron plate can be lifted in a horizontal position, but if mud or the like adheres to the spread iron plate, the adsorbing force is weakened and the steel plate falls on the way. There is danger. The present invention solves such a problem, and the suspended body is kept in a horizontal posture,
It can be lifted safely and labor-saving.

[0008]

SUMMARY OF THE INVENTION Under the above-mentioned problems, the present invention provides at least two suspended objects having corners in a diagonal direction of the suspended object, each of which is provided with a lifting member such as a wire. A hanging metal fitting that is connected and hung, wherein the hanging metal fitting is inserted into and surrounds a corner of the body to be hung, and is protruded in a direction opposite to the insertion direction and is fixed to an upper surface of the inserting part, and is inserted.
The hole where the lifting member can be connected around the upper part of the
Slots where hands can be inserted at positions off the
And a handle comprising a vertically elongated handle .

When the present invention employs the above means, a lifting member such as a rope is connected to the hole of each handle and the upper end thereof is collectively lifted, the suspended body is lifted in a horizontal posture. . Since the lifting force acting at this time is converted into a force for moving the insertion portion toward each other, there is no possibility that the lifted body will fall out of the insertion portion, which is safe.

[0010] Further, according to the present invention, in the above means, the insertion portion comprises an upper member, a lower member and a side member,
Among these, a means in which the end of the lower material to be lifted inserted in the opposite direction is formed into a triangular shape having a sharpened center, and the upper surface thereof is inclined toward the end to form a blade, and in this means, the lower material Means for projecting the end in the opposite direction of insertion of the lifted body from the end surface of the upper material. This facilitates insertion of the insertion portion into the suspended body.

Further, a means is provided in which an end of the insertion portion in the direction of insertion of the suspended body is cut out so that when the suspended body is inserted, the corner thereof can be seen. It can be visually recognized that the corner of the suspended body is looking through, and the insertion of the insertion portion can be confirmed.

In addition, there is provided a means in which the handle is formed of a vertically long handle, and a long hole is formed in a portion outside the hole so that a hand can be inserted. Handling becomes easy, and particularly, insertion and removal of the insertion portion from the suspended body are facilitated. Also, a means is provided in which the bottom surface of the handle body insertion reverse end end in the opposite direction is projected downward by a predetermined length to form a contact portion. The contact of this part with the suspended body is ensured, slippage is prevented, and safety is improved.

The suspended body to which the suspension fitting is applied may be any suspended body having at least two corners, but may be a flat rectangular plate which is the most difficult to handle. Therefore, the most suitable application of this hanging bracket is
The laid iron plate described above is conceivable.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a hanging fitting according to the present invention, FIG. 2 is a longitudinal sectional view, FIG. 3 is a plan view, and FIG. 4 is a front view. In this hanging fitting 10, a corner of a lifted body is inserted. It is composed of an insertion portion 12 surrounding four sides, and a handle portion 14 fixed above the insertion portion and capable of connecting a lifting member. In addition, both the insertion part 12 and the handle part 14
Generally, it is made of a strong metal such as iron.

The insertion portion 12 has a shape surrounded on all four sides by an upper member 16, a lower member 18, and both side members 20, 22, and into which a corner of the suspended body 24 is inserted. . In this case, the angles of the side members 20 and 22 are set so that two sides sandwiching the corner of the suspended body 24 are along the side members 20 and 22 (if the rectangular member is dedicated to the square plate, the two members 20 and 22 are used).
Is set to 90 °).

It is desirable that the corner of the end of the insertion portion 12 in the insertion direction (hereinafter referred to as the insertion direction) of the suspended body 24 is cut out in a predetermined range. This is because when the suspended body 24 is inserted, the corner thereof is looked through, so that it can be confirmed that the suspended body 24 has been sufficiently inserted. Further, it is preferable that the end of the insertion portion 12 in the direction opposite to the direction in which the hoisting body 24 is inserted (hereinafter, referred to as the insertion reverse direction) is protruded in a triangular shape whose center is sharpened in the insertion reverse direction.

Among them, the projecting amount of the lower member 18 is
And the upper surface thereof is formed on the blade 18a so as to be inclined toward the end. This is to facilitate insertion into the lower surface of the suspended body 24.

The handle portion 14 extends in a direction opposite to the insertion direction from above the insertion portion 12, and usually has a vertically long handle 26 fixed above the insertion portion 12 by welding or the like. Pattern 2
6, a hole 28 is formed above the insertion portion 12, and a long hole 30 is formed at a position outside the hole 28.

The hole 28 is for passing a lifting member 32 such as a wire, and the long hole 30 is for inserting a hand or the like. Further, the bottom surface of the end portion in the direction opposite to the insertion is made to protrude by a certain length (the portion other than this portion is left loose), and this is used as a contact portion 26a. This is to ensure that this part (only) is brought into contact with the suspended body 24.

Next, a method of using the hanging fitting 10 having the above-described configuration will be described. FIG. 5 is a perspective view showing the situation. The four sides of the insertion portion 12 hold the grips 14 at the diagonal corners of the suspended body 24 by hand or the like, and the corners of the suspended body 24 are taken in. As shown. Therefore,
The distance between the upper member 16 and the lower member 18 is required to be equal to or larger than the thickness of the suspended body 24, but it is preferable that there is not much difference from the viewpoint of safety.

In order to facilitate the above operation, in the case where the suspended objects 24 are placed one on top of the other, it is preferable to displace them so that a space exists below this corner. That is, it is preferable to place each of them in a staggered direction, or to place them in the same direction without corners.

However, this operation is possible even when the suspended body 24 is in contact with the ground or the suspended body 24 below. That is, the lower member 18 of the insertion portion 12 is
The lower member 18 is inserted into the lower surface of the to-be-lifted body 24 when the lower member 4 is applied to the lower surface and pulled by hand or hit with a hammer or the like. At this time, if the tip of the lower member 18 is formed on the blade 18a, the insertion is extremely easy even when the suspended body 24 is in close contact with the ground or the like.

The insertion of the insertion portion 12 into the corner of the suspended body 24 is performed sufficiently deeply until the both members 20 and 22 follow the suspended body 24. At this time, if the opposite end of the insertion portion 12 is cut off, this is surely confirmed.

When the above operation is completed, the hole 2
8 is passed through a lifting member 32 such as a wire (a ring provided with a ring at the end) or the like, and the upper end of the lifting member 32 is bundled and lifted by a crane hook 34 or the like. It should be noted that the linking structure between the handle 26 and the lifting member 32 is not limited to the hole 28 described above.

In this case, since the hole 28 is formed above the insertion portion 12, and only the contact portion 26a of the handle portion 14 contacts the suspended body 24, the pulling force of the lifting member 32 is reduced. 10 act in a direction approaching each other (see FIG. 2), and even if the insertion of the insertion portion 12 is insufficient, the hanging metal fitting 10 is attached to the suspended body 2.
There is no escape from 4.

On the other hand, the lifting angle of the lifting member 32 (the angle with the suspended body 24) is θ, and the lifting member 3
Assuming that the tensile force of No. 2 is P and the friction coefficient between the suspended body 24 and the handle 26 is μ, P sin θ · μ> P cos θ → μ>
If the relationship of 1 / tan θ is satisfied, the hanging bracket 1
There is no zero slip.

If the normal metal has a coefficient of friction μ between metals, there is no slipping if the hanging angle θ is 20 ° or more (even if slipping, it is a direction in which the insertion portion 12 is inserted deeply. As described above, there is no problem in safety). Considering the balance of the lengths of the lifting members 32, the lifting angle θ is preferably about 45 °.

After the lifted body 24 has been moved to another location as described above, it is lowered to lift the lifting member 3.
2 and the hanging fitting 10 is removed. In this case, if the space below the corner of the suspended body 24 is a space, this operation is easy, but even if it is in close contact with the ground, the insertion portion 12 is slightly pulled out with a hand or a hammer. When the handle portion 14 is rotated, one of the side members 20, 22 in the opposite direction end a serves as a fulcrum, and the handle 14 is easily removed (see FIG. 3).

The use of the hanging fitting 10 allows the suspended body 24 to be safely lifted and lowered in a short time. In this case, the suspended body 24 is made of a laid iron plate of the above-described standard. The working time is shown in comparison with the conventional method. The work is performed by laying the hanging metal fitting 10 on the iron plate, lifting it up, and placing it at a predetermined position.
Were performed 10 times in the order of removing the average, and the average value was taken.

According to the result, the time of the hanging metal fitting 10 is 5.2 minutes, while that of the hanging metal tool is 10.5 minutes.
12. For those who pass the wire through the hole (pre-drilled),
It took three minutes. As you can see, this hanging bracket 1
If 0 is used, the working time can be greatly reduced.

Although the embodiments of the present invention have been described above, the present invention may be embodied in various other modified forms. For example, the use of the hanger is not limited to two in the diagonal direction, and three or more may be used.
Further, the suspended body is not limited to the square plate, but may be any one having corners. Further, the suspended body is not limited to the one made of iron.

[0032]

As described above, the use of the hanging fitting according to the present invention allows a rectangular plate such as a spread iron plate to be lifted in a horizontal (horizontal) posture. At this time, since the pulling force of the lifting member acts to bring the lifting bracket inward,
The hanging bracket is safe from being detached from the suspended body.

Therefore, by using this hanging bracket,
Accurate stacking and unloading of a flat rectangular plate at a predetermined location does not require much skill, so that labor can be saved in a short time. In addition, if it is hung horizontally, it is less affected by wind and the like, so that it is safe in this respect.
