Patent application number | Description | Published |
20090062079 | Stepping exerciser having actuatable handle - A stepping exerciser includes a spindle rotatably supported on a base, a pair of foot supports rotatably supported on the base and arranged to be moved up and down and stepped by a user and pivotally coupled to the spindle in order to drive and rotate the spindle, a pair of handles rotatably supported on the base and arranged to be rotated or swung by the user and connected to the spindle to selectively drive and rotate the spindle. The spindle may thus be continuously driven by the foot supports and the handles alternatively. A follower may be secured on the spindle to increase a moment of inertia of the spindle, and a wheel may be coupled to the follower to apply a retarding force to the follower and the spindle. | 03-05-2009 |
20090069134 | Dual idler structure for an elliptical trainer - A dual idler structure of an elliptical trainer can tighten a transmission belt, without easily causing the belt to be slipped upon rotating clockwise or counterclockwise. By operating an upper and a lower stopping bolt to abut an upper and a lower idler set, resilience to the idler sets by the transmission belt upon rotating clockwise or counterclockwise is prevented, such that the belt is prohibited from being easily slipped. | 03-12-2009 |
20090111663 | Elliptical exercise machine - An elliptical exercise machine in which a raise angle of an elliptical path can be adjusted consists of a foot base, a pair of arms, a pair of foot pedaling members, and a raise angle member. When handle parts are held by hands, an opposite exercise can be taken by a left and right grip pole, as the arms are coupled to pedal rods, and a roller slides on a link rod. When both feet step on pedals, the pedal rods will slide on the link rods which drive a pulley to operate, by a function of the foot pedaling members, to achieve a purpose of workout. Furthermore, by using the raise angle member, the pedal rods and the link rods will have a change of raise angle, and the raise angle of the elliptical path is adjusted. | 04-30-2009 |
20090181831 | Safety device for folding treadmill - A folding treadmill includes a frame pivotally coupled to a seat, a tread base having a motorized endless treadmill belt and having a front portion pivotally coupled to the frame for allowing the front portion of the tread base to be moved up and down relative to the seat by the frame, and a switching device having one switching member attached to the frame, and another switching member attached to the tread base for selectively switching off the motorized endless treadmill belt when the tread base is moved upwardly to the upward folding position and for preventing the motorized endless treadmill belt from being operated inadvertently and for preventing the users or children from being hurt inadvertently. | 07-16-2009 |
20100197466 | Athletic apparatus with non-linear sliding track - An athletic apparatus includes two rotary wheels installed to a frame, a pair of tracks disposed on the frame and tilted relative to the frame, a pair of pedal mechanisms slidably attached to the tracks and each having a pedal, a pair of rocker arm mechanisms having upper ends attached to the axle rod and lower ends coupled to the pedal mechanisms, a pulley attached to the frame and a steel rope engaged with the pulley and coupled to the pedal mechanisms, two linking belts coupling the lower ends of the rocker arms to an elastic belt which is engaged with the rotary wheels, a belt wheel and two gear wheels installed to a shaft rod of the frame, and the tracks are curved and tilted or inclined relative to the frame. | 08-05-2010 |
20110034304 | Weight lifting exercising device - A weight lifting exercising device includes a number of weight plates slidably attached to a frame with a weight guide rod, two cam members pivotally attached to the frame, two cables coupled between the cam members and the weight plates for moving the selected number of the weight plates up and down along the weight guide rod, and an operating device engaged with the cam members for rotating either of the cam members to actuate either of the cables to move the weight plates up and down along the weight guide rod and for allowing the user to lift and to exercise the weight members either by pulling or pushing a force transfer member and for training or exercising the lower or the upper muscle groups of the users. | 02-10-2011 |
20120014033 | Static electricity eliminator - A static electricity eliminator includes a clip device for attaching to a user, an adaptor for attaching to an object, and an electric cable coupled between the clip device and the adaptor for transmitting a static electricity from the user to the object and for suitably reducing or eliminating a static electricity from the user and for preventing the result of static electricity buildup and discharge from being occurred on the user, the clip device includes two pivotal levers having a jaw member at one end and a hand grip member at another end, the adaptor includes a cover mounted to a housing and electrically coupled to the electric cable, and includes one or more magnetic members for attracting to the object. | 01-19-2012 |
20130011258 | Wind turbine with gale protection - A wind turbine includes a nacelle pivotally supported on top of a tower and having a tail rod, a rotator blade device mounted to the nacelle, a tail vane extended from the tail rod, two horizontal stabilizers mounted to the sides of the tail vane, a stable flap attached to the tail rod and located below one of the horizontal stabilizers, and a pivotal flap pivotally attached to the tail rod and located below the other horizontal stabilizer and pivotal relative to the tail vane to selectively engage with the horizontal stabilizer by a strong wind, and to generate a side force onto the tail vane, and to pivot the wind turbine and to deviate the wind turbine from a headwind and to prevent the wind turbine from being over-rotated or burned or damaged by the gale or strong wind. | 01-10-2013 |
20130028737 | Adjustable wind turbine generating device - A wind turbine includes a nacelle supported on top of a tower and having a chamber for receiving a coil, a spindle rotatably and slidably engaged in the nacelle and having one end extendible out of the nacelle, a rotator blade device mounted onto the spindle, a rotor attached to the spindle and movable relative to the coil, and a spring biasing member for moving the rotor relative to the coil, and the rotator blade device is movable toward the nacelle with a head wind, and the rotor is movable relative to the coil to adjust a torque between the coil and the rotor when the spindle and the rotor are moved relative to the coil with the rotator blade device, and the rotator blade device is movable away from the nacelle with the spring biasing member. | 01-31-2013 |
20130029808 | Cycling exercise machine having adjustable element - A cycling exercise machine includes a housing rotatably attached to a shaft of a stationary base and having two channels, a carrier having two levers slidably engaged in the channels of the housing respectively, a foot support attached to the carrier, a latch attached to the housing, and a spring biasing member engaged with the latch for biasing and forcing the latch to engage with either of the levers and to anchor and retain the carrier and the levers and the foot support to the housing at the required or predetermined position and for allowing the users of different statuses or postures or sizes or dimensions or legs to suitably actuate or operate the cycling exercise machine. | 01-31-2013 |
