本案はソリツドゴムタイヤをもつて構成した健
康器用フライホイールの慣性モーメントを増大す
る装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for increasing the moment of inertia of a health care flywheel constructed with solid rubber tires.
従来実施されている健康器用フライホイールは
自転車用のリムにソリツドゴムタイヤを取付け、
その慣性モーメントにより走行時に近い負荷を得

し足にかかる負荷を均一にして従来の健康器用フ
ライホイールの欠点を解消することを目的として
なされたものである。 The conventional health flywheel is a bicycle rim with a solid rubber tire attached to it.
The moment of inertia is used to obtain a load similar to that when the vehicle is running. However, this device has the disadvantage that it cannot fully satisfy the requirement for a large moment of inertia. Therefore, the purpose of the present invention is to increase the moment of inertia, smooth the rotation of the flywheel, and even out the load on the feet to eliminate the drawbacks of conventional flywheels for health care.

したものである。 The present invention will be explained below with reference to an embodiment shown in the drawings. When using a bicycle wheel, a solid rubber tire 3 having grooves 2 of a required width along the outer circumferential surface is attached to the rim 1, and the circumference of the tire is Groove 2 on the surface
A metal ring 4, which is heavier than the specific gravity of rubber and whose inner diameter is smaller than the outer diameter of the tire, is press-fitted into the inner diameter of the tire, and a groove edge 5 prevents it from coming off. Then, the ring is fixed to the tire 3 with a tap screw 6. Since exposing the ring 4 may spoil the appearance of the flywheel, a cover 7 covering it is made of rubber or plastic as shown in Fig. 7. The cover 7 is formed as shown in FIG. 5, and is fitted into the mounting grooves 8 provided on both sides of the tire 3 with the ear edges 9 on both sides of the cover 7, which covers the outer peripheral surface of the tire, as shown in FIG. It is designed to be attached to the tire 3.

るものである。 Since the present invention is constructed as described above, in addition to the weight of the solid rubber tire, it is possible to adapt to the requirement of a large moment of inertia by fixing the metal ring. It has the advantage of being cheaper to manufacture because it can be used. In addition, the weight of the ring can be freely selected by changing the width and thickness of the ring, and the outer circumferential surface of the tire to which the ring is attached can be covered with a cover as described above. Therefore, when using a metal ring, there is no need for post-processing of the ring, and accuracy is not required, so it can be manufactured at a low cost. It has special features and practical effects.
