A differential air pressure system has a pressure bag with windows and preferred folding configuration such that when the bag is folded no window is folded. The pressure bag is supported by a lift support that is proximal to a user control panel and adjacent to or nearly adjacent to the user who is coupled to the pressure bag. A treadmill base for use with differential air pressure equipment is provided. There are various improvements provided to adapt the operations of the DAP system via the use of separate pressure volume and non-pressure volume portions of the treadmill base. Various improvements to serviceability and repairs are provided by placement of components outside of the pressure volume portion or by providing one or more pressure volume access points.

Disclosed are example embodiments of systems and methods for exercise including an exercise machine including a multiple directional force component configured to apply a multiple directional force to an exercise machine-human body interface, the multiple directional force component further configured to provide a divergent intensity to the exercise machine-human body interface to provide the human body with a resistance during a physical exercise and an artificial intelligence (AI) component configured to control the multiple directional force component. In an example, the AI component may control the multiple directional force component based on morphological characteristics and variability of running speed parameters including at least one of stride length, stride frequency, explosive drive force, and arm drive.

This application relates to a treadmill. In one aspect, the treadmill includes a frame structure, a track part configured to rotate with respect to the frame structure, and a rotation unit disposed in the frame structure and rotatably supporting the track part. The track part may include a plurality of slats arranged in a rotation direction and a track belt disposed at both end portions of the plurality of slats and connecting the plurality of slats. The rotation unit may include first rotation members disposed in front and rear of the frame structure. At least one of the first rotation members includes a plurality of grooves arranged apart from each other on an outer circumferential surface of the at least one of the first rotation members in a circumferential direction, to have a surface shape different from an inner circumferential surface of the track belt.

A treadmill with an anti-entrapment function allows a user to stand on the treadmill and includes a running unit, a control unit, and a sensing unit. The running unit includes two lateral bases, a driving roller, a driven roller, and a running belt. Each lateral base has a bottom end portion. The sensing unit includes a guard bar pivotally provided at the bottom end portions and at least one sensing member. When the user is accidentally pulled into the gap between the running belt and one of the lateral bases, the guard bar will be subjected to an external force and thus rotated downward about a rotation axis, thereby driving the at least one sensing member to send a warning signal to the control unit, in order for the control unit to control the rotation speed of the driving roller accordingly, lest the user be pulled deeper into the gap.

Treadmill protective cover and methods of use are disclosed herein. An example system includes a protective cover for a treadmill, a sensor associated with the treadmill or the protective cover, the sensor detecting when an object is near or within an entrapping area between the protective cover and a conveyor of the treadmill, and a controller configured to receive signals from the sensor, the controller allowing the conveyor to freely operate when no objects are sensed within the entrapping area and stopping the conveyor when an object is sensed within the entrapping area.

A treadmill with an anti-entrapment function allows a user to stand on the treadmill and includes a running unit, a control unit, and a detection unit. The running unit includes two lateral bases, a driving roller, a driven roller, and a running belt. Each lateral base has a bottom end portion lower than the running belt. The detection unit includes a transmitter for emitting a light wave and a receiver for receiving the light wave. When accidently pulled into the gap between the running belt and one of the lateral bases, the user or a foreign object is moved by the running belt to the space between the transmitter and the receiver, thus keeping the receiver from receiving the light wave. The receiver sends out a warning signal in response, in order for the control unit to control the rotation speed of the driving roller accordingly to prevent continued entrapment.

A walking training system includes a leg orthosis fitted to a leg of a user, a pulling member coupled to the leg orthosis, a first drive mechanism configured to apply pull force to the pulling member, according to walking motion of the user, a holding device that holds the pulling member at a holding level, at a point between a coupling point of the leg orthosis and the first drive mechanism, and a second drive mechanism configured to change the holding level of the pulling member held by the holding device, according to the walking motion of the user.
