Benefits of technology

The present invention provides a toy top that can change its operation mode while spinning without replacing any component parts. The toy top has a shaft portion with a friction portion that grips the playing surface for high-speed rotation and a tip protruding lower than the friction portion for low-speed rotation. The toy top can automatically change its operation mode from a dynamic attack mode to a static endurance mode when its rotation speed changes. The friction portion is made of rubber with a large coefficient of friction and the shaft portion is made of resin or metal with a small coefficient of friction. The friction portion is easily fixed to the shaft portion, simplifying the manufacturing process and reducing cost.

Problems solved by technology

In the above latter conventional toy top, although the operation mode is automatically changed in the course of spinning of the toy top, the number of components is increased to make the structure complex, causing the problems that production cost increases and the production process is more difficult.

Embodiment Construction

FIG. 1 depicts an embodiment of a toy top according to the present invention. This toy top A is caused to be spun by a starter (not shown) on a playing board B with a playing surface b curved in a concave mirror shape, to thereby play a match against another toy top. The toy top A includes an upper layer member 1 provided with a function of attacking the opponent toy top, a middle layer member 2 determining the height of the toy top, a lower layer member 3 determining the operation mode of the toy top on the playing board B, and a coupling member 4 in a screw shape coupling together the upper layer member 1 and middle layer member 2 (see FIG. 2).

The upper layer member 1 is formed in a disk shape provided at the center thereof with an opening 5 in which the coupling member 4 is inserted. On an outer perimeter surface of the upper layer member 1, attacking portions 6 expanding outward are formed to have a function of contacting the opponent toy top. On a bottom surface of the upper la...

Abstract

A novel toy top capable of changing the operation mode in the course of spinning without replacing a component member constituting the toy top and having a simple structure and a low cost is provided. A toy top to be spun on a playing board with a playing surface curved in a concave mirror shape includes a shaft portion adapted to contact the playing surface, wherein the shaft portion has a circumferential surface provided with a friction portion that exhibits a coefficient of friction larger than the shaft portion at the time of contacting the playing surface, and the shaft portion has a tip protruding lower than the friction portion.

Description

CROSS-REFERENCE TO RELATED APPLICATIONSThis application is based upon and claims the benefit of priority of the prior Japanese Patent Application No. 2010-124, filed on Jan. 12, 2010, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a toy top and, more particularly, to a toy top with an operation characteristic on a playing board changed at a point between the first half and the latter half of spinning of the toy top.2. Description of the Related ArtConventionally, a toy top capable of changing an operation mode by rearranging component members was proposed by the assignee of the present application (refer to, for example, Japanese Utility Model Registration No. 3149383) and has been in practical use. This toy top is configured by layering an upper layer member with a function of attacking an opponent toy top, a middle layer member that determines the height of the toy top, and a lo...
