An improved cross-country skiing simulating exercise machine for providing interactive aerobic conditioning has a base frame, a pair of foot skates movably mounted on the frame, and a pair of arm poles attached to the frame. The frame has two elongate parallel rails, suitably made of extruded aluminum, each having sidewalls with an elongate groove therein with recesses within the grooves thereby forming sidewall tracks. The skates are securely and movably mounted on the rails and have an inclined top surface sloping downwardly in a forwardly direction and a toe kick at their forward end. The arm poles are at the sides of the front end of the frame, and an electronic sensing, control and display assembly is mounted on the frame between the arm poles. An interactive video skate resistance mechanism for automatically adjusting the difficulty of moving the skates is provided. |

DETAILED DESCRIPTION An improved cross-country skiing simulating exercise machine for interactive aerobic conditioning has a base frame, a pair of foot skates with rollers attached to each skate permitting the skates to be movably mounted on the frame, and a pair of arm poles attached to the frame.
The frame has a plurality of elongate parallel rails, suitably made of extruded aluminum, each having sidewalls each with an elongate groove therein with recesses within the grooves thereby forming sidewall tracks.
The rollers of each skate are adapted to be securely and movably mounted within the respective sidewall tracks of the rails to secure the skates to the rails.
The skates have an inclined top surface sloping downwardly in a forwardly direction and a toe kick at their forward end.
The arm poles are at the sides of the front end of the frame, and an electronic sensing, control and display assembly is mounted on the frame therebetween.
It is an object and advantage of the present invention to provide a video interactive exercise machine that simulates cross-country skiing to provide a safe, smooth, challenging and entertaining aerobic workout, wherein the degree of exercise is automatically variable in accordance with what the user sees.
Another advantage of the present invention is that it provides adjustable arm resistance and automatically or manually adjustable leg resistance, independently of each other.
Another object of the present invention is to provide that a resistance cable, connecting the skates to each other through a resistance adjusting friction brake assembly, may readily have its resistance to movement adjusted as not previously heretofore known.
A feature of the present invention is an integral electronic sensing, control and display module that enables the resistance of the exercise machine to change in response to externally generated sensory data, thereby enabling a user of the machine to react to the perceived sensory data, e.
g.
, a video image, while exercising.
The wireless electronic module senses input data and communicates or interlinks it electronically to automatic response means for changing the resistance of the skates to movement while exercise is underway
