Abstract
A treadmill which utilizes provides for a connection between the floor stand and the treadbase which is toward the front end of the treadbase and provides for generally improved support of the front end of the treadbase at higher angles by providing that the lift mechanism is attached to the treadbase at two fixed points a fixed distance from each other. The lift mechanism then utilizes two different motions, the extension of an extension arm and the rotation of a rigid arm, to produce lift. The rotation of the rigid arm generally utilizes a wheel in an enclosed raceway attached to the floor stand.
Claims11
A treadmill comprising:
- a floor stand;
- treadbase including an endless belt thereon;
- a motor for moving the endless belt;
- and
- a lifting mechanism for rotating the treadbase relative to the floor stand about a point of rotation, the lifting mechanism comprising:
- a lift motor attached at a fixed position to the treadbase;
- an extension arm attached at a first end to a fixed position on the treadbase, the extension arm increasing and decreasing in length based on action of the motor;
- a rigid arm attached at a first end to a fixed position on the treadbase, a second end of the extension arm being attached to the rigid arm at a fixed position on the rigid arm;
- and
- two wheels on the rigid arm;
- wherein when the lift motor is activated to increase the length of the extension arm, the increase in the length of the extension arm causes the wheels on the rigid arm to roll relative to the floor stand thus altering the angle of the rigid arm relative to the floor stand and causing the treadbase to incline.
