Abstract

A partially-inlaid treadmill system includes a running deck, a wide belt assembled on two parallel rollers to slide over the running deck, side handrails, a panel for controlling and monitoring the treadmill system, a partition that separates a first part of the treadmill system positioned for access to the user from a second part of the treadmill system that includes mechanisms and electro-electronics for driving the belt, incline devices, belt lubrication, ventilation and regulating devices, an emergency control lever, a drawer, a plurality of directional ventilation openings, and an aisle provided on the same side of the partition as the second part of the treadmill for accessing components of the second part of the treadmill system.

Claims

1. A partially-inlaid treadmill system comprising:

a running deck;

a wide belt that is assembled on two parallel rollers to slide over the running deck, wherein bearings of the rollers are assembled to a rigid structure with at least one of the rollers being actuated by an electric motor;

wherein

foot platforms disposed on both sides of the belt, the foot platforms being coated with a non slip surface;

side handrails that a user may hold provided with control buttons for controlling functions and sensors for monitoring the heart rate of the user,

a panel for controlling and monitoring the treadmill system provided with a viewfinder and control and programming keys;

a partition that separates a first part of the treadmill system positioned for access to the user from a second part of the treadmill system comprising mechanisms and electro-electronics for driving the belt, incline devices, belt lubrication, ventilation and regulating devices,

wherein the side handrails project substantially horizontally and in parallel from the partition within a reach of the user for support and access to the control buttons and the panel for controlling and monitoring the treadmill system is positioned on the partition between and above the handrails;

an emergency control lever located between the handrails;

a drawer provided below the emergency control lever, the drawer being inlaid in the partition

a plurality of directional ventilation openings provided on the partition and positioned toward sides of the panel; and

an aisle provided on the same side of the partition as the second part of the treadmill system for accessing components of the second part of the treadmill system.

2. The partially-inlaid treadmill system according to claim 1, wherein a front roller of the parallel rollers is assembled to a front part of the structure of the treadmill and actuates the belt via a pulley, a transmission belt, and an electric motor placed above the roller, and

wherein blocks that regulate a position of an axle of the roller on the front part of the structure slide on the structure and are pulled by screws for stretching and aligning the belt.

3. The partially-inlaid treadmill system according to claim 1, wherein the incline devices raise or lower an end of the structure for simulating an ascending slope in the treadmill and comprise vertical racks coupled to gears, the gears having a common axle attached through bearings fixed to a support of the structure and actuated by an incline electric motor provided with a speed reducer.

4. The partially-inlaid treadmill system according to claim 1, wherein the aisle is provided with collective clean air units communicating a duct with air that is inhaled through the structure of the treadmill via an aspiration grid positioned near a back roller of the parallel rollers;

the system further comprising;

a low voltage power source and a compressed air system having a compressor and a reservoir;

a central reservoir containing lubricating fluid with a hydraulic pump;

wherein the structure of the treadmill is widened in the aisle and receives electronic equipment placed on higher parts of the structure and in an inner face of the wall.

5. The partially-inlaid treadmill system according to claim 2, wherein the pulley has a diameter and weight for accumulating kinetic energy and stabilizing a speed of the belt;

and

wherein the electric motor that actuates the pulley through the transmission belt is located above same the front roller and fixed to a vertical projection of the structure.

6. The partially-inlaid treadmill system according to claim 5, further comprising:

a controller of the electric motor; and

an interface that receives and sends signals to the panel of the treadmill system, the controller and the interface being attached to the projection.

7. The partially-inlaid treadmill system according to claim 3, wherein the common axle is moved by the speed reducer via an input axle connected to the electric motor that is actuated through an interface that receives commands from the panel.

8. The partially-inlaid treadmill system according to claim 1, wherein the structure is provided with a grid window through which air is inhaled toward a flexible pipe in the aisle by an electric aspirator that directs the air to a duct that runs along the aisle and exhausts the air to the atmosphere.

9. The partially-inlaid treadmill system according to claim 1 wherein pleated curtains are placed above and below a passage of the structure through the partition wall.
