Improvements in a bench is disclosed. The bench is configured so the gap between the seat and the backrest is adjusted as angle of the back rest is changed. The gap is maintained my sliding or translating the backrest or the seat on the frame as the angle of the back rest is changed. This can be with a rack and pinion, a tension strap, or a mechanical linkage. The mechanism converts the angular change of the backrest to a linear translation or an arc translation to alter the position of the backrest, seat, or a combination thereof to prevent contact between the seat and the back rest and prevents creation of a large gap between the seat and the backrest that can cause discomfort. In some embodiments, the gap is adjusted based upon an angle of a constrained brace that locks the backrest at fixed angles.

A muscle-building apparatus for building the muscles of a user performing a physical exercise, comprising a frame on which are assembled a treadmill which is displaceable in a longitudinal direction and in opposite senses, a force generator that supplies an adjustable pushing or dragging force, and a swivelling support mechanically coupled to the force generator for the user to perform a pushing or dragging exercise on the swivelling support.

A mechanical braking system which can provide a brake to a self-powered treadmill, or a dual mode treadmill that can operate in both self-powered and motor-powered modes, that will rapidly halt the motion of the belt or rollers in the event of a power disconnect such as from the removal of a safety key.

The present invention relates to an apparatus (100, 1001, 1002) for physical activity, comprising: a frame (101); a plurality of rollers (203, 204) rotatably connected to the frame (101); a belt (200) mounted on the plurality of rollers (203, 204) and revolving to define moving belt surfaces (201, 202) comprising: an activity belt surface (201) being configured for physical activity of at least one user (301, 701) and delimited by a side of the frame (101), and a return belt surface (202) being configured for revolving the belt (200) in a never-ending loop; the return belt surface (202) is elevated with respect to the activity belt surface (201).

A treadmill has a base with a vertically displaceable platform. A mechanism is provided that resists the downward movement of the platform in response to a load applied to the platform. The mechanism also rebounds the platform upwardly with a force applied to the platform in response to a decrease of a load on the platform. A support structure enables stable vertical positioning of the platform with respect to the base.

A motorized treadmill provided for allowing a user to perform a programed workout. The motorized treadmill includes a base, an endless belt movable relative to the base for allowing a user to exercise thereon, a motor coupled to the endless belt for driving the endless belt to rotate, a signal receiver, and a controller in communication with the motor and the signal receiver. The signal receiver is configured to receive a weight training signal when the user performs the programed workout with free weight equipment. The controller is configured to transmit validated exercise use data when the user is engaging the endless belt. When the signal receiver receives the weight training signal from the free weight equipment, the controller will determine that the user is not engaging the endless belt and stops transmitting the validated exercise use data.

A treadmill includes a base, a motor disposed on the base, and a motor cover. A side of the base is for disposing with a running belt. Another side of the base has a receiving space and an upper opening communicating with the receiving space. The motor is located in the receiving space for driving the running belt. A side of the motor cover is pivotally connected to the base for closing the upper opening, and another side of the motor cover is manipulable to pivot toward the side of the base disposed with the running belt to open the upper opening, and the motor cover is located above the running belt at this time. Thus, the user can manipulate the motor cover to open or close the upper opening without using tools, and the motor cover can be properly placed above the running belt when the upper opening is opened.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame.

An agility trainer apparatus that provides a robotic system that applies forces laterally to a harness worn by a person during walking so as to provide highly controllable interventions targeting locomotor stability.

A force measurement system and a motion base used therein is disclosed herein. The force measurement system includes a force measurement assembly configured to receive a subject, a motion base for displacing the force measurement assembly, and one or more data processing devices operatively coupled to the force measurement assembly and an actuation system of the motion base. The motion base includes a support structure; a displaceable carriage coupled to the force measurement assembly; and an actuation system, the actuation system including one or more actuators operatively coupling the displaceable carriage to the support structure, the one or more actuators configured to displace the displaceable carriage with the force measurement assembly relative to the support structure, the displaceable carriage being suspended below a portion of the support structure.
