Abstract

(57) [abstract] (with correction) [Problem] In the conventional top, a metal mandrel that protrudes up and down is used as a middle man, and an elongated string is wrapped around the main body and thrown out strongly to enjoy the rotation by gaining rotational force, but turning. It was a difficult play for children because it required a guide. There is a problem that there is a danger of throwing it out strongly and scratching the floor surface with a mandrel. Therefore, there are restrictions on the play area such as indoors, and it is not possible to share one top music and keep turning. A beating top has a flat or concave top surface, a cylindrical portion and a conical portion, and a hemispherical rotating shaft core 2 at the center of the lower end. This is a device that can be continuously rotated by obtaining the rotational force by the force of hitting the whip almost horizontally in the side surface of the top of the top. The problem with the top was solved by scratching the floor, avoiding dangers, and simplifying the procedure.

Description

[Detailed description of the invention]

[Technical Field to which the Invention Belongs] The present invention is a device for hitting tops which can give a turning force to a hitting top main body (1) using a whip (3) and can be continuously turned. The initial rotation is performed by inserting the turning rod (4) into the turning hole (1f) on the upper surface and twisting it by hand. The turning force is obtained by tapping the whip (3) in a substantially horizontal direction and by tapping the side surface of the top of the whip rod. It was found that multiple whip strings (3b) of the part could be used as a rotational force by contact friction with the top side surface. The main body of the beating top (1) is mainly made of wood, and wood with a low specific gravity is preferred, but synthetic resins and aluminum alloys that can be easily processed can also be used. The top body, which is limited in shape and mass, is surrounded by a curved surface and a gentle flat surface.The minimum outer diameter and height are 30 mm or more, which prevents the infant and children from holding in the mouth. It has a spherical shape to prevent the risk of floor flaws and injury from falling. The total weight of the top was reduced to 15 g or more and 300 g or less to make it easy to carry as a plaything. The surface of the top is made of wood or colored and enjoyable, but the surface of synthetic resin or aluminum alloy is smooth, so the surface may have irregularities such as round or grooved dents. The rotating shaft core (2) projects in the shape of a hemisphere at the center of the lower end, so that the contact portion with the floor surface is minimized so that the frictional resistance is small and the resistance to rotation is reduced. The materials used include hard book nuts, hard wood, hard synthetic resin, and processed steel plates. The hitting top body (1) of the present invention has a structure comprising a cylindrical portion (1a), a plurality of conical portions (1b) (1c) (1d), and a rotating shaft core (2).

[Prior Art] In a conventional top, a metal mandrel protrudes up and down from the center axis of a main body, and the mandrel is used as a mediator to wrap a long and thin string around the main body of the top and obtain a rotational force by a strong throwing force. It was a difficult play for small children, as it required a procedure for winding and throwing the string. In order to obtain the spinning power of the top, it was absolutely necessary to use a mandrel that protruded up and down in order to wind a slender string around the main body of the top. The rotation of the top is obtained with a strong throwing force, and when it is thrown, the maximum is gradually decelerated due to frictional resistance, so it can not continue to rotate for a long time. Surface, which limits play on the indoor floor. There was a problem that it was not possible for multiple people to play while sharing one spin and turning.

[Problems to be Solved by the Invention] In the present invention, in the conventional top music, a sharp and dangerous metal mandrel that protrudes up and down is eliminated and the floor is scratched by throwing it out strongly. It is difficult for a child who has difficulty getting used to throw a strong ball and throws it at high risk of injury, etc.If the child is not used, the risk of injury is high. There were many problems, such as not being able to play with one person while sharing one spin, and it was not suitable as a playground equipment. These problems were solved by changing the shape and rotation method of the top, simplifying and simplifying.

[Embodiment of the Invention] The hitting top of the present invention has a flat top surface or an outer shape having the outer shape shown in FIG. 2 and having no upper pole protruding from the upper surface within the numerical range shown in Table 1. There is a rectangular turning hole (1f) in the center of the mass adjustment recess (1e). A recess (1e) may be formed on the flat upper surface due to mass balance adjustment, but the shape is the largest external cylinder (1a). And several stages of conical portions (1b) (1c) (1d), and a rotating shaft core (2) having a hemispherical projection at the lower center. The initial rotation was done by inserting the turning rod (4) into the turning hole (1f) and twisting it by hand to give a gentle string. No flaws or dangers on the surface. When the initial rotation starts, the wrist string (3b) of the whip (3) is hit against the top surface in a well-balanced numerical range shown in [Table 1] and [Table 2]. It was devised that it becomes a rotational force and can continue to rotate continuously. The whip used in this operation is within the numerical range of [Table 3] and is determined by the outer diameter of the top and the preferred length of the whip rod [L1]. In this way, it is possible to continuously play the hit tops continuously, and a plurality of people can share and play one hit tops together. The main material used in the hitting top of the present invention is wood, but it is better to use a material with a relatively low specific gravity among the wood.Since the balance of mass is calculated, synthetic resin and aluminum alloy are used because of ease of processing. Is possible. The rotating shaft core (2) can be made of hard and slippery non-infected fruit, vertebra, cypress, cherry blossom, ginkgo, etc., as well as hard synthetic resin, or surface-treated steel plate from the viewpoint of workability and price. . The whip string (3a) of the whip (3a) of the present invention is a whip rod (3a) made of animal hide, processed vegetable fiber, or synthetic resin fiber processed into a thin string having a width of several millimeters. Use wood, bamboo, synthetic resin, etc. for).

[Effects of the Invention] The present invention has the following effects as compared with the conventional top music. 1. Because there is no strong throw, there is no danger of injury, and you can play indoors without damaging the floor. 2. It is easy to turn, so even small children can turn around. 3. Rotating force is given by the whip, so it can be turned continuously. 4. One player can share the top hit and turn it continuously by multiple players. 5. Since a metal mandrel is not required, workability is improved, productivity is increased, and prices are reduced.
