Patent number: 6923746Abstract: To improve tracking, an exercise treadmill is provided with a frame including molded plastic pulleys, having an integral gear belt sprocket, an endless belt extending around the pulleys and a motor operatively connected to the rear pulley to drive the belt. The pulleys are molded out of plastic and have a diameter of approximately nine inches. A mold and method for producing large diameter treadmill pulleys having an integrally molded sprocket are also disclosed. A deck underneath the running surface of the belt is supported by resilient members. A positive lateral belt tracking mechanism is used to correct the lateral position of the belt. A belt position sensor mechanism is used in combination with a front pulley pivoting mechanism to maintain the belt in the desired lateral position on the pulleys. The exercise treadmill also includes a lift mechanism with an internally threaded sleeve engaged to vertically aligned nonrotating screws. A user display of foot impact force on the belt is also provided.Type: GrantFiled: December 6, 1999Date of Patent: August 2, 2005Assignee: Brunswick CorporationInventors: Richard E. Skowronski, Kenneth F. Lantz, Jose A. Leon, Donald James Alexander, George Kolomayets, Vincent C. Adams, Eugene B. Szymczak, Edward W. Minnich, Wade K. Totzke, Tomas F. Leon

Patent number: 5403252Abstract: A climbing exercise apparatus is provided having a frame on which two pedals are pivotally mounted to provide a user with a vertically reciprocating exercise movement, and a control panel for user input and output. A dynamic break, alternator or the like applies a variable level of resistance (via a suitable transmission) against the user's movement. The resistance varies over time in accordance with a control signal generated by a computer. The value of the control signal is independent of the rate at which the user steps. A display successively displays images of hills. Each hill is associated with one of the series of values, and that value is graphically represented as part of or in visual association with the hill image.Type: GrantFiled: November 3, 1992Date of Patent: April 4, 1995Assignee: Life FitnessInventors: Tomas F. Leon, Robert L. Hood, Robert E. Quast, David J. Thum, Emil S. Golen
