Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic mounting device that can be removably mounted on a magnetic surface by magnetic force, and particularly in any form on a mounting surface (magnetic surface) having a complicated shape. A magnetic mounting device that can be mounted.

[Conventional technology]

Magnetic mounting devices are known in the art, for example the device of US Pat. No. 2,280,437. In this device, a pair of magnetic pole plates are selectively magnetized or demagnetized by a movable permanent magnet assembly so that they can be mounted on or removed from a magnetic surface. This device has a drawback that it can be mounted only on a flat surface or a slope in principle.

U.S. Patent as a known technique for mounting on a complex-shaped surface
There is one shown in No.1,171,818. This is a device in which one end of a magnetic pole plate is attached to a magnetic pole of an electromagnet, and the other end is changed in length so as to contact a surface having a complicated shape. However, this structure can only be applied to specific surfaces and cannot be used for surfaces of other shapes.

The magnetic mounting device of US Pat. No. 3,968,986 registered on July 13, 1976 has electromagnets connected to each other, and the magnetic poles of the electromagnets are integrated. With such a structure, it is possible to contact one of the magnetic poles with the surface of the attachment. However, if the surface is not flat or slanted, when one magnetic pole comes into contact with the mounted object, the other magnetic pole cannot come into contact with each other and a gap is formed, so that a magnetic circuit is not formed. Therefore, such a structure cannot be said to be effective.

[Problems to be solved by the invention]

Therefore, the problem to be solved by the present invention is to solve the above-mentioned drawbacks and to form a complete magnetic circuit between both magnetic poles on the surface of a non-device having a diverse and complicated shape.

Since both magnetic pole portions are the same, only the magnetic pole portion 26 will be described. The magnetic pole portion is inserted into the magnetic pole portion chamber 27 which is partially formed by the side plate 28. The side plate is provided with a window 29 and has an upper end 30 and a lower end 31. The magnetic pole portion is made of a magnetic material. A plurality of elongated magnetic members 32, each of which has a stud 33 protruding outward in the frame of the window 29.
Is embedded. The tack and the upper and lower ends of the window prevent the magnetic material from falling out of the magnetic pole chamber.

The position of the magnetic material is adjusted according to the shape of the mounting surface, and the pressing means 34 compresses it into a fence shape. In this embodiment, a screw 35 having a handle 36 is used as the pressing means.The screw is turned to fix the magnetic material at a predetermined position, and the screw is loosened to adapt the apparatus to another mounting surface. Can be readjusted. Here, "fence-like" is not limited to the flat or rectangular magnetic material array shown in FIG.

The body is equipped with a shaft 40 which is exposed to the outside for mounting tools and other devices.

When the north pole and the south pole face the non-magnetic material part (made of non-magnetic material such as aluminum), a magnetic path cannot be formed between the magnetic pole parts, so that this device cannot be attracted to the mounting surface.

On the contrary, when the handle is turned to the position indicated by the alternate long and short dash line in FIG. 2, a magnetic path is formed between the magnetic pole and the armature, the magnetic flux passes through the magnetic pole portion, and the device is attracted to the mounting surface. The mounting surface shall be made of magnetic material such as iron or steel.

Are parallel.

Magnetic pole portions 60 and 61 made of elongated magnetic materials 62 and 63 are inserted into the magnetic pole portion chambers, respectively. Even if the magnetic pole portion is at the highest position, the lower end of the magnetic pole portion has a length protruding from the main body. As shown in FIG. 1, the magnetic material is flat and provided with tacks to limit the sliding range. The end walls 65 and 66 hold the magnetic material like a fence.

The pressing means 70 comprises a cam 71 mounted between the stop plates 72 and 73 protruding from the main body. This cam is a hinge pin
It is attached by 74. The cam has a pressing portion 75 when the handle 76 is on one side and a releasing portion 77 when the handle 76 is on the other side (Fig. 5). When the cam is turned from the position shown in FIG. 5 by the handle, pressure is applied to the magnetic pole through the floating plate 77 and the pins 78 and 79, and the magnetic pole is held at the set position. When the handle is turned in the opposite direction and the release portion of the cam faces the floating plate 77, the pressing force is released, and the magnetic material can slide.

A permanent magnet 80 is provided in the bottom portion in contact with each magnetic material, and its width is the same as the width of the magnetic pole portion. In this embodiment, the permanent magnet does not rotate or move in any way.

This rotatable configuration can be employed in each embodiment of the present invention.

The magnetic pole portions may be arranged outside the inner non-magnetic cylinder 125. The non-magnetic cylinder is partially cut away so that the permanent magnet can come into contact with the magnetic pole portion. When the pressing means 126 is loosened from the outside of the magnetic pole portion, the magnetic material can slide. If necessary, an elongated magnetic rod or a magnetic wire is used as the magnetic material.

FIG. 11 shows an embodiment in which a plurality of this apparatus are combined.
The main use of this structure is to hold instruments, but it is also used as a transportation device within the range of its holding ability.
