JPS5831582Y2 - Magnetic suction pen for moving pieces - Google Patents

Description

[Detailed description of the invention] This invention is based on the idea that in board games such as Ki, Shogi, and Chess that are miniaturized for in-car games, the pieces are small and it is difficult to directly attach and detach the pieces to and from the board using fingers, etc. Therefore, the purpose of this is to use magnetic attraction to easily move pieces onto the board.

This invention forms a magnetic circuit with a pair of adsorption pieces attached to the lower end of the pen for moving pieces, a permanent magnet built into the pen, and the pieces to be moved, so that the pieces are magnetically attracted to the pen and permanently To provide a magnetic attraction pen in which a piece is detached from the pen by separating a magnet from an attraction piece.

Hereinafter, a description will be given based on the embodiments shown in the drawings.

The pen case 1 is made up of a lower half part 1A and an upper half part 1B glued together, and is hollow inside to form an internal space H, into which a compression spring 2 and a sliding body 3 are inserted. , a permanent magnet 4 is fixed to the tip of the sliding body 3.

A pair of adsorption pieces 5, 5 made of a flat magnetic material (a flat iron plate in the embodiment) are opposed to each other with an appropriate distance between them, and the bent part 5C at the base end is connected to the groove 6 in the lower half 1A of the pen case. At the same time, the suction pieces 5, 5 are pressed against the side wall of the lower half 1A of the pen case by the protrusion 7 at the tip of the lower half 1A, and the suction pieces 5, 5 are attached to the lower half 1A of the pen case. Fixed.

The tips 5a, 5a of the attraction pieces 5, 5 are exposed from the lower end P of the pen case 1, and in the normal position of the sliding body 3 shown in FIG. base 5b,
It is located between 5b.

The knob 9 protruding from the sliding body 3 is located in the upper half 1 of the pen case.
It passes through hole 8 of B and is exposed on the peripheral surface of the pen case.
In the normal position, it is on the A side and displays magnetic attraction, and when the sliding body 3 is pushed up against the compression spring 2 and is placed on the opening side, it displays no magnetic attraction and no attraction.

In the embodiment, the magnetic suction pen of the present invention is used to attach and detach pieces to and from the base, and an iron disc with a diameter of 8 mm is attached to a small base 10 with eyes of about 8 mm pitch in white or black (or black). The board 10 has a game board display sheet 12 formed by printing 19 vertical and horizontal lines on a thin vinyl sheet on the surface of a magnetic rubber sheet 11. It is made up of adhesive.

Of course, the magnetic suction pen of the present invention can be used as a shogi board or other game board, or as a shogi piece or other game piece, if desired.

When using the magnetic suction pen of the present invention, the knob 9 of the sliding body 3 is set to the normal position A side as shown in FIGS. 1 and 3.
As shown in FIG.
, 5b, the tips 5a of the suction pieces 5, 5,
Magnetic poles N and S appear at 5a.

Therefore, the magnetic adsorption pen can be attached to the piece 13 of the desired color (black or white).
When the tips 5a, 5a of the suction pieces are brought close to the upper surface, since the mutual spacing between the suction pieces 5, 5 is smaller than the diameter of the pieces (4 mm in the embodiment), one piece 13 is attached to the suction pieces 5, 5.
As a result, a magnetic loop is formed by the attraction of the pieces 13 (see FIG. 3), and the attraction force of the piece 13 to the attraction pieces 5, 5 is strong.

In addition, the magnetic poles formed at the tips 5a, 5a of the attraction pieces 5, 5 act only on the closest magnetic piece 13, so that two or more pieces do not fly up and become attracted (permanent magnet It is desirable to select the strength of the permanent magnet 4 so that the magnetic force of the permanent magnet 4 is not too strong.

As shown in Fig. 3, when - pieces are attracted to the attraction pieces 5, 5,
Permanent magnet 4 - Attraction piece 5 - Piece 13 - Attraction piece 5 - Permanent magnet 4
Since a closed-loop magnetic circuit is formed, after a piece is attracted, the magnetic force does not affect other pieces, and two or more pieces will not be connected (one piece attracted to another piece).

Therefore, only one desired piece 13 is attracted to the pen.

After moving the pen that has attracted the piece 13 to the desired position on the game board 10, push the knob 9 toward the non-suction opening side.
As shown in FIG. 4, the permanent magnet 4 separates from the attraction pieces 5, 5, and the piece 13 is no longer magnetically attracted to the piece 13. The piece 13 separates from the pen and falls onto the game board 10, as shown in FIG. The game is played with piece 13 in parallel.

Although the pieces to be attracted by the magnetic attraction pen of the present invention are circular in the embodiment, it goes without saying that they may be pentagonal, quadrangular, or any other suitable shape.

As described above, the present invention applies the magnetic force of a permanent magnet built into the pen to a piece to be moved via a pair of adsorption pieces whose tips are exposed from the bottom end of the pen and which face each other with a space between them. Since the magnetic attraction force of the pieces forms a closed-loop magnetic circuit, the magnetic attraction force for the attracted pieces is strong, and after magnetically attracting a desired piece, It can eliminate the magnetic effect on other pieces and prevent two or more pieces from attracting each other in succession.
Furthermore, the magnetic circuit is cut by pushing up the sliding body to which the permanent magnet is fixed against the elastic force of the compression spring toward the upper end of the pen case, so that the magnetic circuit is cut off by pushing up the sliding body. The magnetic adsorption effect can be eliminated, the pieces can be easily removed from the pen, and the small pieces can be easily arranged at desired positions on the game board.
This is a practical application of a very small game board for use in cars.
