Description

[Detailed description of the invention] This invention relates to a roulette-style teaching tool in which the rotating directing body stops rotating at the center of the roulette compartment.The purpose of this invention is to place the rotating directing body above the start mark of the roulette training board. This rotating directing body is rotated to the center position of the roulette section by moving the rod, and then the device rotates it by inertia.This is a novel structure that has never existed before, and is highly entertaining. Our goal is to provide roulette-style teaching tools.

That is, this invention is a distant relative of the above-mentioned purpose, by providing a magnetically permeable roulette training board on the top surface of the roulette board, and in this pedestal, from the lower position of the start mark of the roulette training board. A moving operation rod is provided whose tip head is guided to move to the center position of the radial roulette section, and the rod is placed on the start mark of the roulette training board and is moved to the center of the roulette section by moving the rod. A rotary directing body having a spherical rotary contact that is rotated to a position and rotated by inertia at the center position, and a spherical rotary contact of the rotary directing body and a magnetic element provided at the tip head of the rod. both are made of attracting magnets, or one is made of a magnet and the other is made of a magnetic material; It is characterized by the fact that the axis of rotation is attracted to a tilted state and rotates by moving the rod.

An embodiment of this invention will be explained below with reference to the drawings. In the drawing, 1 is a synthetic resin table with a magnetically permeable roulette training board 2 made of cardboard fitted into the opening on the top and fixed with adhesive. Bar guides 3a, 3b, and 3C as shown in FIGS. 4 and 5 are installed horizontally inside the holder, and a bell mounting plate 5 having a protruding circular protrusion 4 is attached to the holder's circumferential portion 1a.
It is provided so as to extend inward from the.

Note that the upper surface of this table 1, that is, the roulette training board 2
is inclined forward and downward at an inclination of, for example, about 5 degrees in a direction perpendicular to the bar guides 3a to 3c.

On this roulette training board 2, a star-shaped start mark 6 is displayed on one end side along the horizontal direction of the rod guides 3a to 3C, and the center position of the radial roulette section 7 (
This position is located between the rod guides 3a and 3b, and is the radial center of the circumferential portion 1a of the table.

), a star-shaped rotation marker 8 is displayed, and within the radial roulette section 7 are score numbers, addition,
Disc-shaped training card 9 with printed subtraction calculation problems, etc.
(The illustrated example shows a training card with score numbers printed on it.)
are juxtaposed in a recombinable manner.

In addition, instead of using the above-mentioned training card 9, a plurality of roulette training boards 2 are prepared in which training items similar to those printed on this card are printed directly in the roulette section 7, and the roulette training boards 2 are used. It may also be used by being replaceably fitted into the device stand 1.

Reference numeral 10 denotes a moving operation rod inserted between the rod guides 3a, 3be3c in the mold 1, which moves from a position below the start mark part 6 of the roulette training board 2 to a position below the center of the roulette partition part 7 (rotation mark It has a tip head part 11 that moves laterally to a lower position of the part 8) and an outer end knob 12 for moving the rod, and a magnetic element 13 (in this embodiment (which is considered to be a magnetic body) are fitted and fixed.

The movement of the rod 10 at a position below the center of the roulette section 7 is stopped when the rod end head portion 11 collides with the tip stopper portion 14a of the latching tongue piece 14 cut into the rod guide 3C. .

Reference numeral 15 denotes a rotation directing body placed on the start mark 6 of the roulette training board 2 and rotated from this position to the center position of the roulette section 7;
6 (in the case of this embodiment, the magnetic element 1 of the rod head portion 11
Fig. 2A shows a circular holder 17 which is fitted and fixed with a spherical surface exposed (consisting of magnets that attract each other), and a circular holder 17 which is mounted by being sandwiched between the holder protrusions 17a and 17b.
The roulette training board 2 is tilted downward, so that the rotation axis 1 is tilted with respect to the vertical axis 1' as shown in FIG. It is adsorbed.

Therefore, since the rotational directing body 15 comes into attraction contact with the spherical rotary contact 16 at an eccentric point, it is possible to move the rod 10 and move the rod while being magnetically attracted to the magnet 13 of the rod end head portion 11. It moves in one direction from the position of the start mark part 6 to the center position of the roulette partition part 7, and at the center position where the rod end head part 11 stops moving, it is rotated by inertia as it is.

Note that the rotational movement of the rotational directing body 15 as described above can be achieved even if the roulette training board 2 is not tilted, if the rotational directing body 15 is configured to have a biased center of gravity so that the rotational axis 1 is inclined. In other words, it is possible even if it is horizontal.

Reference numeral 19 shown in FIGS. 4 and 5 is a bell striking spring attached to the side of the rod head portion 11 via a pin, and when the head portion 11 moves close to the center of the roulette compartment 7, The end striker 19a strikes the bell body 20 by the elastic force of the bar 19a, and a bell sound is emitted at the end of the drawer movement of the bar 10.

In the above embodiment, the magnetic element 13 of the movable operating rod 10 and the spherical rotary element 16 of the rotary directing body 15 are both composed of magnets that attract each other.
3 and the spherical rolling contact 16 may be made of a magnet, and the other may be made of a magnetic material such as iron.

The roulette-style teaching tool of this invention is as explained above, so if you place the rotation directing object on the start mark of the roulette teaching board and pull the moving operating rod outward,
The rotating directing body rotates and moves to the center position of the roulette compartment, and at the center position of the roulette compartment where the tip head of the rod stops, it continues to rotate inertia, so that the rotating directing body stops rotating at the pointing position. By looking at the teaching items, the prescribed learning can be done in an interesting way, and it is especially interesting that the rotating directing object moves while rotating and rotates by inertia at the center position of the roulette compartment, which makes it interesting as a teaching material. It has an increasing effect.
