Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bicycle-type exercise machine that is used as a health equipment or a game equipment and is pedaled by a user.

(Prior art) As a conventional bicycle exercise device, for example,
As described in Japanese Utility Model Publication No. 44511, an electric motor is used to change the relative position of the handle and the saddle according to the load on the pedals, so that a forward-leaning posture can be achieved. As described in 2006, there is a known structure in which a handlebar and a saddle are linked and swung back and forth by a link mechanism in response to rotation of a pedal.

(Problem to be Solved by the Invention) However, as mentioned above, although conventional bicycle exercise machines are configured so that the handlebars and saddles can be tilted back and forth, there is no bicycle exercise device that is configured so that they can be tilted left and right. , In actual bicycle riding, not only on straight roads, but also on straight roads.
Climbing and dismounting requires bending from side to side, and the user must tilt their riding position forward, backward, left and right, and balance the center of gravity by shifting their weight, and conventional equipment has not been able to meet these demands. Recently, there has also been a growing demand to improve the training effect or enhance the gameplay by imposing a more severe riding position.

It is an object of the present invention to provide a bicycle-type exercise device that allows the handlebars and saddle to be tilted back and forth and left and right at any angle, which not only trains leg strength (but also develops a sense of balance and enables more complex training). That is.
