Definitions
- the following description relates generally to exercise equipment, and in particular to electric treadmills.
- Electric treadmills are one of the most popular types of modern exercise equipment and are now commonplace both in gyms and in home exercise rooms.
- Treadmills typically include a platform with a conveyor belt that moves from front to back. A user stands on the treadmill platform and must match the speed of the conveyor belt by walking or running forward.
- the conveyor belt is unpowered and only moves if a user is walking or running on it. More commonly, however, the conveyor belt is powered by an electric motor connected to a user interface at the front of the treadmill. The user can control the speed of the conveyor belt, and therefore the speed the user is required to walk or run, by setting the motor speed on the user interface.
- the platforms of treadmills tend to provide a stiff moving surface which can create discomfort to the user during exercise routines.
- some designers have provided a coating to the moving surface, such as rubber or carpeting, in order to reduce the impact felt by a user.
- this coating technique has not provided the necessary relief to the user or been effective, because the moving surface even with rubber or carpeting coating has been known to maintain its stiffness. Accordingly, the coating insufficiently reduces the impact felt by the user during an exercise routine.
- Other approaches to reduce impact been to increase thickness of the conveyor belt in order to absorb more shock, but these approaches have not been entirely successful. This is because in traditional treadmills as belt thickness increases, a motor with greater drive power is required.
- an apparatus with a continuously movable surface with at least two belts includes a platform with a front end and a rear end. and a first front pulley mounted inside the platform adjacent to the front end of the platform. At least a first rear pulley is mounted inside the platform adjacent to the rear end of the platform.
- a first conveyor belt is looped around the first front pulley and the first rear pulley.
- a second conveyor belt is looped around the second front pulley and the first rear pulley. The first conveyor belt is nested in the second conveyor belt.
- a continuously movable surface is formed so that when a user strikes the continuously movable surface, the second conveyor belt reduces the impact and absorbs shock felt by the user.
- an apparatus with a continuously movable surface with at least two belts includes a platform with a front end and a rear end, and a first front pulley mounted inside the platform adjacent to the front end of the platform. At least a first rear pulley is mounted inside the platform adjacent to the rear end of the platform. At least a second rear pulley may also be mounted inside the platfonn adjacent to the rear end of the platform.
- a first conveyor belt is looped around the first front pulley and the first rear pulley.
- a second conveyor belt is looped around the second front pulley and the second rear pulley. The first conveyor belt is nested in the second conveyor belt.
- a continuously movable surface is formed so that when a user strikes the continuously movable surface, the second conveyor belt reduces the impact and absorbs shock felt by the user.
- a treadmill with dual belts includes a platform with a front end and a rear end, and a first front pulley mounted inside the platform adjacent to the front end of the platform.
- a second front pulley may also be mounted inside the platform adjacent to the front end of the platform.
- a first continuous conveyor belt is looped around the first front pulley and a second continuous conveyor belt is looped around the second front pulley to provide the platform with a top surface movable between the front end and the rear end of the platform.
- At least a first rear pulley is mounted inside the platform adjacent to the rear end of the platform.
- a second rear pulley may also be mounted inside the platform adjacent to the rear end of the platform
