Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spinning top toy for children that can be rotated without using a string.

[0002]

[Prior art]

 Generally, in order to turn a spinning top, the spinning force must be applied to the spinning top. Therefore, in the past, for example, a type such as a begoma that gives a rotational force by twisting a string on the bottom of a top, or a type that applies a rotational force by attaching a string to the mandrel of the top is used. is there.

[0003]

[Problems to be solved by the device]

 In both types, the spinning top varies depending on the method of winding the string and the technique of pulling the string and turning the top. In addition, a fairly advanced technique is required to rotate the top powerfully. In particular, there was a problem that the spinning top could not be turned properly when a complicated technique could not be used, such as in an infant.

[0004]

[Means for solving problems]

 In this device, a convex part that serves as the center of rotation is formed in the center of the bottom surface, and a plurality of hooks are formed on the circumference centered around this convex part. A locking hole is provided on the circumference of the ring, and the top and bottom of this locking hole are provided with an inclined locking part with an angle of inclination toward the inside centering on the convex part. An elastic mandrel formed by an inverted conical coil spring, which is locked to the hook part and whose tip is grounded and serves as the center of rotation, and a cylindrical central hollow part formed through the central part. A cylindrical groove is formed on the outside of the coil, the first coil spring is inserted in the central cavity, the upper end of this coil spring is fixed to the upper end of the central cavity, and the lower end of the coil spring is bent into a key shape. It forms a stop and it projects from the lower end of the central cavity as a free end. A second coil spring was inserted into the cylindrical groove, and a pin that protruded from the bottom surface of the cylindrical groove and locked in the locking hole of the main body to prevent reverse rotation was provided, and a protrusion was provided on the outer peripheral wall. A driver is also provided.

[0005]

[Action]

 When the driver element 9 is inserted into the mandrel 2, the locking portion 16 of the coil spring 14 is locked in the locking hole 5. Next, when the driver 9 is rotated, the coil spring 14 is wound in the winding direction. When the rotation of the driver 9 is stopped, the pin tip end portion 17b protruding from the pin hole 13 is locked by the inclined locking portion 6, so that the coil spring 14 is not rewound.

[0006] When the rotation of the driver 9 is restarted, the tilting direction of the tilt locking portion 6 is gradually shallowed in the rotation direction of the driver 9, so that the pin tip portion 17b smoothly and easily tilts. The coil spring 14 is slid from the stopper portion 6 and slides on the upper surface of the flat portion 1c of the upper case 1a of the top body 1 so that the coil spring 14 is further tightly wound.

Then, the middle finger and the index finger are put on the ring-shaped protrusion 10 of the driver 9, and the tip of the mandrel 2 protruding from the upper surface of the driver 9 is pressed by the thumb, and the locking portion 16 of the coil spring 14 is pressed. The locking between the locking hole 5 and the locking hole 5 is released, and the top body 1 falls on the floor surface and rotates around the elastic mandrel 7 as a rotation axis.

[Example of device]

 An embodiment of this invention will be described in detail with reference to FIGS. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a perspective view, FIG. 3 is a plan view, FIG. 4 is a sectional view of a driver, and FIG. 5 is a bottom view of the driver.

In FIG. 1 to FIG. 3, reference numeral 1 denotes a top body, and a lower case 1b formed in a substantially bowl shape and an upper case 1a formed in a truncated cone shape have their open ends opposed to each other. The core body 1 is formed by the mandrel 2 serving as the center of rotation protruding upward from the upper case 1a.

A convex portion 3 serving as a rotation center is formed in the center of the bottom surface of the top body 1, and a plurality of hook portions 4 are formed on the circumference around the convex portion 3. . Further, a locking hole 5 is provided on the circumference centered on the mandrel 2 projecting from the center of the top of the top body 1. As indicated by an arrow A in FIG. 3, an inclined locking portion 6 having an inclination angle that gradually becomes shallower in the rotation direction of the top body 1 is formed by cutting and raising in the inner direction of the top body 1.

Reference numeral 7 denotes an inverted conical elastic mandrel, which is formed of a coil spring, and a conical shaped large-diameter end portion is formed on the bottom surface of the top body 1 so as to be located on the center line of the mandrel 2. It is engaged with the hook portion 4 and has a rotation center portion 8 which is grounded at the tip. The elastic mandrel 7 can be attached to and detached from the hook portion 4.

Reference numeral 9 denotes a driver for applying a rotational force to the top body 1, and as shown in FIGS. 4 to 5, is a columnar member having a diameter substantially equal to the diameter of the upper surface of the flat portion 1c of the upper case 1a. , An upper case 9a and a lower case 9b, and a ring-shaped projection 10 is integrally provided on the outer peripheral wall of the upper end opening of the lower case 9b. A cylindrical central hollow portion 11 is formed so as to penetrate through the inner center of the driver element 9, and the outside of the central hollow portion 11 has a hollow inner portion having a smaller diameter than the central hollow portion 11. A groove 12 is provided as a recess, and a pin hole 13 is transparently provided on the bottom surface of the cylindrical groove 12.

Inside the central cavity 11, a cylindrical first coil spring 14 is inserted along the inner wall, and the upper end of this coil spring 14 is, as shown in FIG. It is locked and fixed to the projection 15 formed on the upper end of the core, and the lower end is bent into a hook shape to form a locking portion 16. The locking portion 16 is a free end of the core hollow portion 11. It is projected from the bottom edge.

Reference numeral 17 denotes a pin for preventing the driver element 9 from rotating in the reverse direction. The pin 17 is locked in the locking hole 5 formed in the upper surface of the top body 1 and presses the second coil spring 18. The pressing piece 17a is fixed to one end.

The pin 17 is inserted into the cylindrical groove 12 with the pressing piece 17 a in contact with the bottom surface and the pin tip portion 17 b protruding from the pin hole 13. In addition, a cylindrical second coil spring 18 is inserted along the inner wall in contact with the presser 17a, and the upper end of this coil spring 18 is abutted on the inner surface of the upper case 9a. It is configured so as not to protrude from the groove 12.

Next, the action and operation will be described. First, when the driver element 9 is attached to the top body 1, the mandrel 2 is inserted into the coil spring 14 inserted into the central cavity 11. When the driver element 9 is rotated in this state, the engaging portion 16 of the coil spring 14 protruding from the central hollow portion 11 is engaged with the engaging hole 5, and the driver element 9 is attached to the top body 1.

When the driver 9 is further rotated in this state, the coil spring 14 is wound in the winding direction. At this time, when the rotation of the driver 9 is stopped, the pin tip portion 17b protruding from the pin hole 13 is locked to the inclined locking portion 6, so that the coil spring 14 is not rewound.

Therefore, when the drive element 9 is restarted to rotate, the inclination locking portion 6 is inclined so that the inclination direction becomes gradually shallower in the rotation direction of the drive element 9, so that the pin tip portion 17b can be smoothly moved. Then, the coil spring 14 is slid from the inclined locking portion 6 and slides on the upper surface of the flat portion 1c of the upper case 1a of the top body 1 so that the coil spring 14 is further tightly wound.

In this way, when the driver element 9 is rotated many times, the coil spring 14 is sufficiently wound, so that the top body 1 has a sufficient rotational force accumulated therein. Therefore, when the rotation of the driver 9 is stopped, the pin tip portion 17b is locked by the inclined locking portion 6 located nearby, and the driver 9 is fixed.

Then, the middle finger and the index finger are put on the ring-shaped protrusion 10 of the driver 9, and the tip of the mandrel 2 protruding from the upper surface of the driver 9 is pressed by the thumb, and the engaging portion 16 of the coil spring 14 is pressed. The locking between the locking hole 5 and the locking hole 5 is released, and the top body 1 falls on the floor surface and rotates around the elastic mandrel 7 as a rotation axis. At this time, since the elastic mandrel 7 is formed of a coil spring, the elasticity of the coil spring allows the top body 1 to rotate while jumping while rotating.
