Description

[Detailed explanation of the invention] This invention relates to a potter's wheel toy used as a teaching material by children and students in lower grades.The purpose of this invention is to be able to rotate a clay turntable at high speed in one direction by simply pressing down on a lever. To provide a highly interesting potter's wheel toy with a relatively simple structure.

Hereinafter, the potter's wheel toy of this invention will be explained according to the drawings. In the figure, 1 is a potter's wheel table consisting of a pair of front and rear split plates 1a and 1b in the shape of a penguin. On the right side of the potter's wheel table 1 is a vertically long lever A fitting hole 2 is provided. Note that the platform split bodies 1a and 1b are butt-connected by four screws 3 as shown in FIG.

Reference numeral 4 denotes a fan-shaped gear pivotally supported at a lower position close to the lever insertion hole 2 in the potter's wheel table 1, and an operation lever 5 integrally protruding from the end of this sector-shaped gear is connected to the lever fitting hole 2 of the potter's wheel table 1. It protrudes outward from the insertion hole 2. A coil spring 6 biases the lever 5 upward, and is stretched between the spring hook part of the fan-shaped gear 4 and the inner protrusion 7 of the potter's wheel stand. A crown gear 8 is pivotally supported above the sector gear 4 in the potter's wheel stand 1, and has a coaxially integrated interlocking gear 9.

Reference numeral 10 denotes a small gear that meshes with the sector gear 4 which is pivotally supported by a movable rotation shaft 12 in a shaft swing hole 11 which is curved in the sector gear rotation direction of the potter's wheel table 1 (table split bodies 1a, 1b); Large gear 1 engaging and disengaging from gear 9
3 are provided coaxially and integrally. Reference numeral 14 denotes a final stage gear that meshes with the crown gear 8 which is rotatably supported around a vertical axis on the upper end shaft bearing part 15 of the potter's wheel table 1. A rotary disk 17 is fitted and fixed.

FIG. 1 shows a gear state in which the large gear 13 is separated from the interlocking gear 9. In this state, when the lever 5 is pressed down by hand, the sector gear 4 rotates clockwise in FIG. At the same time as the large gear 13 is rotated, the movable rotating shaft 12 moves diagonally along the shaft idle hole 11, so that the large gear 13 meshes with the interlocking gear 9, and the rotation of the gear is caused by the rotation of the crown gear 8 and The information is transmitted to the final gear shaft 16 via the final gear 14, and the clay rotary disk 17 is rotated at high speed in one direction.
3 disengages and disengages from the interlocking gear 9. Since the potter's wheel toy of this invention is as described above, it is possible to rotate the clay turntable at high speed in one direction by simply pressing down on the lever, and it is relatively simple and can be used as a teaching material by children and students in lower grades. It is possible to provide a highly interesting potter's wheel toy with a unique structure.

Claims (1)

[Scope of utility model registration request] A potter's wheel stand shaped like an appropriate toy and having a vertically elongated lever insertion hole on its side surface, a fan-shaped gear pivotally supported within the wheel stand, and a lever insertion hole of the wheel stand that projects from the end of the fan-shaped gear. a push-down operation lever that is biased upwardly by a spring and projects outward from the wheel; a crown gear that is pivotally supported at a position above the fan-shaped gear in the wheel stand; and an interlocking gear that is coaxially integral with the crown gear; and the wheel stand. A small gear that meshes with the sector-shaped gear that is pivotally supported by a moving rotation shaft in a shaft swing hole that curves in the rotating direction of the sector-shaped gear, a large gear that engages and disengages with the interlocking gear, and a large gear that is perpendicular to the upper end shaft bearing part of the potter's wheel table. A potter's wheel toy comprising: a final stage gear that meshes with the crown gear that is rotatably supported around an axis; and a clay rotary disk fitted to an upwardly protruding shaft portion of the final gear shaft.
