Abstract
The disclosed stationary exercise bicycle apparatus has a road device unit supporting a substantially free-wheeling endless treadmill, and a motion coordinator for coupling a substantially conventional bike unit with both its steering and drive wheels riding on the treadmill. The motion coordinator has a rail extended crosswise to and over the upper exposed run of the treadmill, and under the rotatable pedals of the bike unit. A pair of laterally rigid telescoping members are secured firmly between the bike unit and the rail. The securing structure includes a guide carried on the rail that holds the bike unit substantially fixed longitudinally on the treadmill and that allows lateral steering and limited tilting of the bike unit relative to the treadmill, to simulate riding the bike unit on a real road surface.
Claims12
Indoor exercising apparatus for use with a conventional bike unit having front steering and rear drive wheels spaced apart on a wheel base, and pedals supported rotatably between the front and rear wheels, the exercising apparatus comprising the combination of
- a road device unit having stationary laterally spaced sides and a non-powered substantially free-wheeling endless treadmill defining an exposed upper run extended laterally between the spaced sides and longitudinally a distance greater than the wheel base of the bike unit;
- motion coordinator means coupling said bike unit and road device together, with both wheels simultaneously supported on the upper treadmill run;
- and
- said motion coordinator means comprising:
- rail means extended generally between the laterally spaced sides, with clearance overlying the upper run of the endless treadmill and underlying the bike unit proximate the rotatable pedals;
- and
- a pair of laterally rigid telescoping members, means securing one end of one telescoping member firmly relative to the bike unit proximate the rotatable pedals, means guiding the opposite end of the other telescoping member for free movement along the rail means and laterally of the endless treadmill, means allowing substantial relative rotation of the securing and guiding means about the longitudinal axis of the telescoping members, and means allowing only limited tilting of the telescoping members relative to the rail means;
- whereby said motion coordinator means is operable to hold the bike unit substantially fixed longitudinally on the treadmill while allowing lateral steering and limited tilting of the bike unit relative to the treadmill, to simulate riding the bike unit on a real road surface.

- motion coordinator means coupling said bike unit and road device together, with both wheels simultaneously supported on the upper treadmill run;
- and
- said motion coordinator means comprising:
- a rail extended generally between the laterally spaced sides, with clearance overlying the upper run of the endless treadmill and underlying the pedals, and a carrier guided on the rail to move laterally of the endless treadmill;
- a pair of laterally rigid telescoping members;
- means securing one of the telescoping members relative to the bike unit proximate the pedals, and means securing the other telescoping member relative to the carrier;
- means allowing substantial relative rotation of the securing means about the longitudinal axis of the telescoping members;
- and
- means allowing limited tilting, laterally of the longitudinal axis of the telescoping members, of the securing means at the bike unit relative to the carrier;
- said tilt limiting means comprising a surface fixed relative to the rail and a member threaded relative to the other telescoping member and disposed to be threaded toward and away from the surface to defined adjustable gaps, each gap being set to provide a specific degree of allowable tilt of the telescoping members relative to the rail;
- whereby said motion-coordinator means is operable to hold the bike unit substantially fixed longitudinally on the treadmill while allowing lateral steering and limited tilting of the bike unit relative to the treadmill, to simulate riding the bike unit on a real road surface.
