A resistance regulating device for a wheel of a training device is disclosed. The resistance regulating device comprises a rotary mechanism pivotally connected with a stationary mechanism and a motor with other components to rotate the rotary mechanism and hence a distance between magnets of the rotary mechanism and the wheel is changed. In addition, an optical detection device may be used to detect and define a minimum resistance and a maximum resistance and hence to adjust a resistance in a stepless manner. An emergency brake mechanism may be further employed.

A magnetically-controlled damping device has a fixing disk, a rotating disk, a plurality of friction-proof sleeves, a plurality of brake shoes, a plurality of magnets, an elastic element, and an operating element. The rotating disk has a plurality of guiding rods sleeved by the friction-proof sleeves respectively. By adjusting a distance between the magnets and a rotating wheel, a damping value of the magnetically-controlled damping device can be adjusted. Moreover, since the friction-proof sleeves are between the guiding rods and the guiding grooves, the guiding rods do not wear out. The magnetically-controlled damping device can provide a more stable damping value and a longer service life.

A reformer includes a generally rectangular frame, a movable carriage mounted on the frame for movement between head end and foot end of the frame, and a plurality of springs biasing the carriage toward the foot end of the frame. The carriage has at least four roller wheels. A carriage drag adjustment device in accordance with the present disclosure generally includes a drag generator configured to apply an opposing force to at least one roller wheel of the wheeled reformer carriage, a mounting assembly fastening the drag generator to the wheeled reformer carriage, and an adjustment mechanism coupled to the drag generator to adjust the amount of drag applied to at least one roller wheel mounted to an underside of the reformer carriage, thereby opposing movement of the wheeled reformer carriage between the head and foot ends of the frame.

A bicycle trainer, including a base, permitting fore and aft movement and a frame, supported by the base. Also, a seat and a handlebar assembly and a pedaling assembly is supported by the frame. The handlebar assembly is rotatably engaged to the frame, and is supported by a tongue, that is hinged to the base so as to permit horizontal rotation, and the handlebar assembly is attached to the tongue at a position removed from the hinge. Turning the handlebars causes the frame to move laterally.

An exercise apparatus providing a User multiple different exercises, including both resistance movements and isometrics. The User interacts with the apparatus by grasping a bar. A resistance mechanism is symmetrically mounted on a second bar and provides infinitely variable resistance to the User, as well as soundproof operation. A vertical column allows infinite positioning of the bars for different exercises, and a bench provides support. The User can change the exercise resistance by verbal commands, or the apparatus can sense the torque applied by the user to the apparatus and vary the exercise resistance in response to the force applied by the User or the speed at which the user is moving the bar. The apparatus can be battery powered and operated at locations where electric service is unavailable, or in zero gravity. To verify accuracy, the resistance can be calibrated against a known quantity of weight.

Embodiments of a strength training apparatus and related methods are provided. In one embodiment, a strength training apparatus may include a tower, a first arm and a second arm each pivotally coupled with the tower and each being configured to be selectively positionable independent of each other at multiple angles relative to each other, a first pulley coupled to an end of the first arm, a first cable extending through the first arm and the first pulley, a second pulley coupled to an end of the second arm, a second cable extending through the second arm and the second pulley, a magnetic mechanism coupled to the first cable and the second cable and configured to provide multiple levels of resistance to a user pulling on the first cable and/or the second cable, and a control panel located on the tower.

A spinning bike includes a transmission wheel, a flywheel and a resistance braking device. The transmission wheel is disposed on the bike frame. The flywheel is made of the metal material, and driven by the transmission wheel to rotate. The resistance braking device includes a magnet assembly, a resistance adjustment member, a control member, a manual brake assembly and a resistance control assembly. The resistance adjustment member is connected to the bike frame. The magnet assembly is pivotally connected on the resistance adjustment member. The control member is connected to the magnet assembly. The manual brake assembly is disposed on a handlebar of the bike frame, and includes a brake handle and a brake control wire. The resistance control assembly includes a motor, a control interface and a resistance control wire.

A controlled stimulation device used either alone or in conjunction with a treatment device to reduce amount of pain a patient may experience during a treatment with the treatment device.

The present invention relates to the field of wearable robotic devices that physically interact with humans, and in particular refers to a wearable exoskeleton, in particular for the upper limb. The invention refers to an electro- or magneto-rheological fluid type semi-active joint purposely conceived to be used to make the exoskeleton. It comprises a first body and a second body, slidably coupled to each other, with a flow mode rotating configuration, which allows to have a fluid flow moved by a pressure gradient induced by the circular movement of a piston in a chamber, with constructive simplicity and decrease of wear.
