  • Patent number: 11969623
    Abstract: An elliptical trainer with incline adjustment mechanism includes a frame, a link assembly, a pedal assembly and an adjustment mechanism. The frame has a base member and a supporting member. The supporting member defines an inner space. The link assembly has two swinging arms. The pedal unit has two pedal arms. The adjusting mechanism has a shaft, a sleeve member, two coupling members, and two links corresponding to the coupling members. When the sleeve member moves along the shaft, the coupling members and the links are driven by the sleeve member, such that the pedal arms are driven to move relative to the base member. The shaft is disposed in the inner space, preventing the shaft from protruding outward. The coupling members are pivotally connected to the supporting member to evenly distribute the weight of the coupling members and the links.

  • Patent number: 11938369
    Abstract: 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.

  • Publication number: 20220362653
    Abstract: 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.

  • Patent number: 10632340
    Abstract: A treadmill includes a frame, a driving member and a running belt. The frame includes a base, a front rotating shaft and a rear rotating shaft. The driving member has a motor and a transmission member drivable by the motor. The motor is installed between the front rotating shaft and the rear rotating shaft and is located adjacent to the front rotating shaft. The transmission member is adapted for driving the front rotating shaft to rotate. The running belt winds around the front rotating shaft and the rear rotating shaft, and is drivable by the motor to rotate relative to the base. By installing the motor between the front rotating shaft and the rear rotating shaft, an overall length and size of the treadmill is reduced for minimizing storage space.

  • Publication number: 20160339288
    Abstract: An elliptical trainer with a resilient unit includes a frame, an exercising unit axially disposed on the frame, a pedal unit pivotally mounted to the exercising unit, a damper for providing a damping resistance to the pedal unit, a guide unit for supporting the pedal unit and guiding the pedal unit to slide thereon, and a pair of resilient units respectively disposed in proximity to the pivoted junctions between the exercising unit and the pedal unit for enabling a pair of rear end portions of the pedal unit to be constantly kept far from a pair of pivot-connection portions of the exercising unit so that an inertial-elastic force is produced during operation of the elliptical trainer.
