Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple lifting or transporting aid;
The purpose is to easily flatten objects such as electric refrigerators, desks, bookshelves, glass plates, and other relatively heavy objects with flat surfaces that do not have handles or grip areas when lifting, moving, or transporting them. The purpose of this invention is to provide an auxiliary tool that can be attached to a handle part to form a handle part.

The configuration will be described below with reference to the drawings shown as examples.

1 is a magnetic substrate, which is placed on a flat plate and has rubber, synthetic resin,
Magnetized by containing ferrite powder or other magnetic material in a polymeric material or other flexible material, and magnetized so as to cover the entire bottom surface of the magnet substrate.

The front side can be printed or otherwise used to instruct precautions on use or to be used for advertisements and promotions. 2 is a circular base; 3 is a handle integrally formed on the circular base 2 having a central bulge, and protruding from the circular base;

In the illustrated example, the grip of the handle portion is formed by bridging a diagonal line connecting two corners of a square magnet substrate. The magnet board 1 is flat and made of rubber,
The handle part 3 formed on the circular substrate 2 is flexible enough to be made of synthetic resin, polymeric material, etc., and has enough flexibility to be able to bend from the base to the left and right, and has elasticity that allows it to return to its original position. 4 indicates a main body having a flat portion.

Since the present invention has the above-described configuration, the auxiliary tool can be adsorbed onto a flat plate such as a glass plate or an outer wall surface of a refrigerator.

That is, when the flat magnetic substrate 1 is placed on the flat surface of the main body 4 as shown in FIG. Even if an attempt is made to lift it by pulling on it, outside air will not enter around the magnet board, and a vacuum will be formed in the center of the inside, resulting in a vacuum negative pressure state. Therefore, by pulling up the handle portion 3, the suctioned main body can be lifted and moved. When the flat surface of the main body 4 is made of a steel plate or other magnetic material, the magnetic substrate 1 and the main body 4 can be attracted more easily and reliably by magnetic force.

When the handle part 3 is provided so as to bridge the diagonal of the square magnet substrate 1, the pull-up by the handle part starts from the center of the center and becomes considerably wider until it reaches the corner of the periphery. Therefore, the adhesion force due to negative pressure is strong, and the negative pressure generated by the entire area of the flat magnetic substrate acts.

Therefore, even when the main body is heavy or has no handle and is difficult to move, it is now possible to construct a handle that is easy to attach. In this way, when the magnetic board is pulled up by the handle, the circular base has an equal pulling force in all directions around the periphery and does not exert a concentrated force on one part, so it acts to pull the magnetic board only from the center. Therefore, since only the center of a flat magnetic substrate made of rubber or plastic is pulled without the surrounding area floating, a stable vacuum state is created at the center.
Adhesive force due to negative pressure is constantly formed.
The example shown in Fig. 5 shows an example in which two of the auxiliary devices of the present invention are used in hair, and the handle portion can be easily constructed by adhering one device to each side of an electric refrigerator. It became.

5 indicates a belt that connects a pair of auxiliary tools to each other.

The belt 5 is adjustable and, in the example shown, is provided so that it can be pulled through the bottom of the refrigerator. In the case of a flat plate like a glass plate or a large iron plate, there is no handle to lift and transport it, which is inconvenient.
By using the product of the present invention, since the flat surface has no irregularities, it can be easily adsorbed, and the vacuum state created during pulling up allows support by negative pressure, making handling convenient. If the main body itself is not magnetic, pressing force is applied by the weight of the handle and the relatively large planar area.
Adhesion to the main body 4 is ensured. In the case of a large and heavy object such as a refrigerator, safety can be further enhanced by assisting with a belt 5 or the like. The auxiliary tool can be easily removed by flipping up a portion of the magnetic board by hand, since the overall suction is loosened and the negative pressure caused by the vacuum is eliminated by the intrusion of outside air.

As mentioned above, when using the auxiliary tool of the present invention, the suction force of the magnet and the negative pressure of the vacuum ensure stable adsorption and adhesion to the main body at all times, so it is easy to use when transferring or transporting relatively heavy objects. It is also effective and safe to use.

Moreover, removal after use can be easily done by flipping up a part of the end of the magnetic board. In the present invention, two pieces are usually used at the same time as a pair, and in this case, safety can be further enhanced by connecting a belt between the auxiliary tools in case of an emergency. As mentioned above, not only when the main body is made of a magnetic material that reacts with magnets, but also when it does not contain a magnetic material, the magnetic board is pushed by the negative pressure caused by the vacuum and the weight of the handle. A safe adhesive force is generated by the pressing force, and it can be reliably attached to any body as long as it has a flat surface, so it has a wide range of applications.
