An arm extension apparatus comprising a propulsion blade comprising a top half and a bottom half, wherein the top half is generally straight and wherein the bottom half comprises a curve, and wherein the bottom half comprises a proximal end and a distal end, and wherein the distal end comprises a foot, and wherein the foot comprises two split toes.

An incline mechanism for a treadmill includes a threaded rod supported by an upright structure. The threaded rod and a lift motor are connected to the upright support above the front end of an exercise deck. The threaded rod is threaded onto a threaded coupler. The threaded coupler is connected to a lift trolley connected to the front end of the exercise deck. As the lift motor rotates the threaded rod, the threaded coupler may move along the length of the threaded rod, thereby changing the inclination of the exercise deck.

A treadmill power station is connected between a treadmill and its power outlet. The treadmill power station contains a power consumption sensor that reads information about the usage of the treadmill by externally analyzing its power consumption pattern. Information that can be derived in this manner includes, but is not limited to, the user's speed, distance covered and step count, as well as the general power consumption trend for the treadmill itself. The power station may contain a relay to activate or deactivate power outlets on the power station.

A treadmill having a curved treadmill deck is provided. Two curved side frames are disposed at two sides of the treadmill frame. Front and rear end ends of each curved side frame are higher than a middle section thereof. Inner sides of the two curved side frames are provided with a plurality of fixing seats, respectively. The fixing seats have fixing holes, respectively. An elastic deck is composed of a plurality of sheets connected side by side. The sheets each have perforations corresponding in position to the fixing holes of the respective fixing seats. A plurality of fixing pins are inserted in the perforations of the sheets of the elastic deck and secured to the fixing holes of the fixing seats. The elastic deck is forcibly fastened by the fixing pins and slightly deformed according to the curvature of the curved side frames to form the curved treadmill deck.

An exercise treadmill includes a machine body, which has at least two rollers, a flywheel linked with one of the two rollers, a support assembly mounted between the two rollers, and a running belt fitted around and engaged with the two rollers and arranged around the support assembly. The exercise treadmill is provided with an accelerating means so that, while a user is walking or running on the machine body, the treading force provided by the user allows the running belt to be accelerated to move around the two rollers for generating electrical power. In addition to improving body heath, the electrical power produced by the treadmill in the training activity can reduce the electrical consumption of city power.

An exercise treadmill includes a frame, an endless belt, and a motor assembly for guiding the belt between front and rear ends of the frame while a user walks or runs on the belt. An impact absorbing assembly is supported beneath a region of the treadmill belt impacted by the user's feet when the user walks or runs on the belt. The assembly has physical properties that serve to define degrees of damping or springiness of the belt in the region impacted by the user. A control system including a user interface is coupled to the absorbing assembly, and the system is configured and operative to vary the physical properties of the assembly in response to an output from the user interface. The region of treadmill belt impacted by the user's feet then simulates a desired one of a number of different surfaces entered by the user on the interface.

A treadmill includes a deck, a first pulley disposed in a first portion of the deck, a second pulley disposed in a second portion of the deck, a tread belt surrounding the first pulley and the second pulley, and a platform incorporated into the deck.

There is described an integrated unweighted gait training system having an unweighting system comprising a computer controller; a gait measurement system in communication with the controller; and a display in communication with the computer controller adapted and configured to provide real-time feedback to a user of the integrated unweighting gait training system. The unweighting system may be a differential air pressure (DAP) unweighting system or a non-DAP unweighting system.

Systems and methods for controlling application of horizontal resistive force to a user walking on a treadmill to provide substantially constant force even if the user changes his or her relative position on the treadmill. The systems and methods can improve the user experience when force is applied while also improving user safety. The system has a cable, a motor, and a system controller. The cable can be coupled to a harness to apply a horizontal resistive force to a treadmill user, and the motor can be coupled to the cable and configured to apply a motor force to the cable. The cable can have an adjustable operative length. The system controller can have a processor communicatively coupled to the motor and configured to adjust the force applied by the motor in response to changes in cable length and a measurement of the actual force applied by the cable.

This invention is related to a mechanism to be used to balance the weight of a patient or a sportsman in rehabilitation or sport based equipment. The purpose of the weight balancing mechanism subject to the invention is to prevent the legs carry the entire weight of a patient or a sportsman during the walking therapy on a treadmill by carrying a portion of their weight. The other purpose of this invention is to adjust the amount of the weight need to be carried. During the phases of walking due to changing the tension of the rope, no change will be occured in the weight of the user is the final purpose of the invention. In order to reach this aim, a mechanism is developed for adjusting the tension of the rope in the light of the rope movements.
