Description

[Detailed explanation of the idea] The present invention relates to a magnetic bar.

Conventionally, the magnets used in iron blackboards and the like have only been circular or bar-shaped, and in view of the fact that there were no magnets that could be used by connecting a large number of them, we provide a magnet bar that can be used by connecting them. The purpose is to

The structure and operation of the present invention will be explained based on the embodiments shown in the drawings.

Reference numeral 1 denotes a bar body having an appropriate length, and this body 1 is made of a synthetic resin material. 2 is a permanent magnet installed in a recess formed on one side (back side) of this main body 1;
Reference numeral 3 denotes a convex portion having a spherical side circumferential surface formed on one side of the main body 1, and 4 a concave groove portion having a spherical side circumferential surface formed on the other side of the main body 1. The convex portion is fitted so that it can rotate up and down. A is an iron plate such as an iron blackboard, and b is a piece of paper attached to the iron plate.

Therefore, when attaching an arbitrary piece of paper b to the iron plate body a, if one magnetic bar suffices, it is sufficient to attach it to one piece, but when two or more magnetic bars are used, it is sufficient to attach it to one bar body 1. One convex portion 3 is fitted into the other concave groove portion 4 of the other bar body 1 to connect the required number of bar bodies. (See FIG. 2) Depending on the object to which it is attached, the connecting portions 3 and 4 of the two main bodies 1 and 1 may be rotated up and down to arbitrary angles to be used in various ways. (Refer to Fig. 3) In this way, the present invention forms a spherical protrusion 3 on one side of the bar body 1 on which the permanent magnet 2 is installed on the back surface, and a side circumferential surface on the other side. Since it is characterized by forming a spherical concave groove part 4, not only can a number of magnetic bars be connected as needed and used in a long length, but also the direction of the connected part can be adjusted. It is now possible to use it by rotating it up and down to change the overall shape to any desired shape, and its practical effects are great as it can always be used to meet the user's needs. be.
