Abstract
An incline mechanism for a treadmill includes a threaded rod supported by an upright structure. The threaded rod and a lift motor are connected to the upright support above the front end of an exercise deck. The threaded rod is threaded onto a threaded coupler. The threaded coupler is connected to a lift trolley connected to the front end of the exercise deck. As the lift motor rotates the threaded rod, the threaded coupler may move along the length of the threaded rod, thereby changing the inclination of the exercise deck.
Claims15
An exercise device, comprising:
- an upright support that comprises a base and a top end, two posts, and two guide tracks;
- an exercise deck having a front end and a rear end, wherein the front end is slidable along the upright support between the base and the top end based on being slidably coupled with the two guide tracks;
- a console connected to the upright support at the top end;
- and
- an incline mechanism located in the upright support, wherein the incline mechanism is connected to the front end of the exercise deck and the top end of the upright support, and wherein the incline mechanism comprises:
- a lift motor, configured to actuate the incline mechanism, located at the top end of the upright support and above the exercise deck;
- and
- a threaded rod that is coupled to the lift motor, that is located between the two posts, and that comprises an upper end connected to the upright support at the top end and a lower end that is free-floating within the upright support.

A method for changing an incline angle of an exercise deck, comprising:
- rotating a threaded rod with a lift motor, wherein the lift motor is located at a top end of an upright support and above the exercise deck, and wherein the threaded rod extends through the upright support to a front end of the exercise deck, the threaded rod being inserted into a threaded coupler connected to a lift trolley, and the upright support comprising two posts and two guide tracks;
- changing a vertical position of the threaded coupler along the threaded rod based on rotating the threaded rod with the lift motor, wherein the threaded rod is located between the two posts and comprises an upper end connected to the upright support at the top end and a lower end that is free-floating within the upright support;
- moving the lift trolley along the two guide tracks based on changing the vertical position of the threaded coupler along the threaded rod;
- and
- adjusting the incline angle of the exercise deck based on the vertical position of the threaded coupler and moving the lift trolley along the two guide tracks, wherein the front end of the exercise deck is slidably coupled with the two guide tracks.
