Publication number: 20090069158Abstract: An elliptical exercising device includes a rotating unit mounted on a support frame, and two link rods connected to the rotating unit such that intermediate segments of the link rods are moved reciprocatively in an elliptical path. A foot support is tiltably mounted on the intermediate segment. A suspending rail is moved with the foot support to be subjected to a gradually varying urging force resulting from movement of the intermediate segment and to be continuously urged to angularly move. A rail engaging rider slidably contacts the suspending rail to be urged by the urging force to angularly move upwards or downwards. An urging force counteracting mechanism is mounted pivotally on the support frame, and is coupled with the rail engaging rider so as to impart a force to counteract an x-axis force component of the urging force to thereby keep the suspending rail in a horizontal position.Type: ApplicationFiled: February 4, 2008Publication date: March 12, 2009Applicant: LIMAX INTERNATIONAL INC.Inventor: Eric Hsu

Patent number: 7226391Abstract: An elliptical exercise device includes a main frame having a rotary shaft defining an axis, left and right link rods having rear ends connected to the rotary shaft for rotation about the axis, left and right arms connected respectively to front ends of the link rods for reciprocal movement, and left and right foot plates connected pivotally and respectively to the link rods and movable along elliptical paths when the rear ends of the link rods rotate. A guide mechanism is connected to the foot plates and the main frame to restrict movement of the foot plates. Each foot plate is substantially horizontal when moving upward or downward from the lowest or highest point of the corresponding elliptical path.Type: GrantFiled: September 16, 2005Date of Patent: June 5, 2007Assignee: Limax International Inc.Inventor: Eric Hsu

Publication number: 20030126743Abstract: The present invention provides an automatic shaping method and structure of fin and connection element. A feeder drives a material belt to enter a punch having a continuous die. The material belt passes a guide device, a bottom die, and a top die of the continuous die to perform operations of punching a central hole, shaping of outer appearance, and hole expansion and drawing. After an a period's interval, the top die is used to shear the material belt, and a pressure piece moves downwards for side shearing. At the same time of shearing, shaped sheet fins are pressured onto the connection element. A stepping device drives the pressure piece to stack the fins on the connection element one by one. The connection elements are arranged at the feeder. The connection element is sent into a positioning device one by one. After the fins are stacked, automatic replacement is performed.Type: ApplicationFiled: January 18, 2002Publication date: July 10, 2003Inventors: Meng-Cheng Huang, Eric Hsu
