Abstract: The purpose of this invention is to enhance the stability of seat up-down adjustment and the aesthetics of a wheelchair. The mechanism is structured by the cart frame, the seat, the linking rod mechanism and the linear motion actuator. There are at least two linking rod mechanisms, each mechanism is composed of several connecting frames and pivot-linked with each others and remains two distal ends for connecting to the cart frame and the seat. The linear motion actuator connects the cart frame and the seat, moves the seat up and down smoothly with help from the stable supporting of the linking rod mechanism. The whole adjustment mechanism is confined in between the seat and the cart frame, which minimizes the needed space and makes a nice figure.

Abstract: An elliptical exercise machine with an adjustable exercising track comprises a framework, having a flywheel, a crank settled on the flywheel, and at least two parallel rails; a wheel assembly, comprising two wheel-shafts arranged at two sides of the crank and two wheels slidably coupled to the rails; a handle-shaft assembly, comprising a pair of handle-shafts disposed at two sides of the framework for being gripped by a user; a stepping-pedal assembly, comprising two pedals coupled to two pedal-shafts which are linked to the handle-shafts; and a pair of adjusting assemblies for shifting positions of joints of the pedal-shafts and the wheel-shafts along the wheel-shafts. By shifting the positions of joints of the pedal-shafts and the wheel-shafts, a minor axis of the elliptical exercising track can be lengthened or shortened and consequently the elliptical exercising track can be non-proportionally scaled.

Abstract: An exercise pattern control method and system for connecting rod locus-type exercise apparatus that establishes an exercise physiology database, an exercise resistance pattern database, and an exercise locus database. Based on the exercise resistance pattern settings and locus exercise pattern settings along with the sensed user heart beat, leg angle speed, and connecting rod length, and other relevant figures so archived, a controller then calculates and processes all the database data and figures to accordingly control the length extension of the connecting rod relative to the current physiological condition of the user. As such, the present invention enables the exercise apparatus to have an operational means of locus configuration to effectively match the physiological condition of the user, thereby achieving utilization convenience, safety, and enhanced exercise efficacy.

Abstract: A treadmill with a shock-absorbing and cushioning structure includes a base frame, and a belt frame, and a cushioning device. The base frame is separated from the belt frame. Thus, the base frame is disposed at a stationary state, thereby enhancing the stability and stiffness of the treadmill. In addition, movement of the belt frame is efficiently cushioned by the cushioning device, thereby enhancing the stability of the treadmill, and thereby reducing the noise in use.
