Description

Description: TECHNICAL FIELD The present invention relates to a bicycle exercise equipment of a type in which a user pedals as a health equipment or a game equipment.

(Prior Art) As a conventional bicycle-type exercise equipment, for example, Japanese Patent Publication No. 61
-44511 and a structure in which the relative position of the handle and saddle is changed in accordance with the load of the pedal by using an electric motor so as to take a forward tilted posture, and Japanese Utility Model Laid-Open No. 61-36651. It is known that the handle and the saddle are interlocked by a link mechanism to swing back and forth according to the rotation of the pedal as described in (1).

(Problems to be Solved by the Invention) However, as described above, the conventional bicycle exercise equipment is configured so that the handle and the saddle can be tilted back and forth, but there is no one configured to tilt left and right.
In actual bicycle driving, there are not only straight roads but also left and right ascending and descending slopes, so the user must lean the riding posture forward and backward and left and right, and balance the center of gravity by shifting the weight. Instruments did not meet these requirements. Further, recently, there has been an increasing demand for enhancing the discipline effect or the playability by imposing a more severe riding posture.

An object of the present invention is to provide a bicycle-type exercise equipment which allows a handle and a saddle to be tilted forward and backward and left and right at arbitrary angles, not only strengthens leg strength but also cultivates a sense of balance and enables more complex training. To do.
