Document Type and Number:
Japanese Patent JP2005095536
Kind Code:
A
Abstract:

To provide hurdles for track and field games which easily fall down by a force within a rule corresponding to each game, and which easily rise after contacting with the ground.

A foot switch mechanism is applied for smoothing vertical motion of a bar of the hurdle for track and field games, and a means to eliminate wire in a mechanism from the foot switch to a fitting pin is provided. An inclination of 45 degrees is imparted to a base part so that a fulcrum position of falling down of the base is constant, and a polygon shape is imparted so as to prevent concentration of stress in an inclination corner of 45 degrees at the time of contacting with the ground.
