摘要： An exercise device is provided including a foot link having a rearward end and a forward end. An adjustable stride mechanism is provided. The adjustable stride mechanism includes a primary gear and a secondary gear. The primary gear is sized larger relative to the secondary gear. A primary crank connects the primary gear and the secondary gear. A timing belt connects the primary gear to the secondary gear. The primary crank and the timing belt enable the secondary gear to rotate around the primary gear. A secondary crank is pivotally attached to the secondary gear and to a foot link. The secondary crank creates an ellipse-shaped path for the foot link as the secondary gear rotates around the primary gear. Thus, the foot link motion combines an at least a dual ellipse motion. An automatic adjusting mechanism can be provided to adjust the adjustable stride mechanism.

摘要： An elliptical exercise device including a frame having a pivot axis, a foot link, a coupling, a swing arm, an engagement mechanism, and a guide system. The foot link has rearward, forward and foot support portions. The foot support portion has a central location. The coupling couples the rearward portion to the pivot axis so that the rearward portion of each foot link travels in a closed path relative to the pivot axis. The engagement mechanism has a first portion coupled to the swing arm and a second portion coupled to the foot link at a location rearward of the central location. The guide system supports the forward portion of the foot link along a preselected reciprocating path of travel as the rearward portion of the foot link travels along its path of travel. The guide system is selectably positionable in a plurality of different positions.

摘要： An elliptical exercise device includes a frame having a first pivot axis and a longitudinal axis, at least one foot link and at least one swing arm. The foot link is coupled to the frame and is constrained to move in an orbital path approximately parallel to the longitudinal axis. The swing arm is also coupled to the frame and has a reciprocating movement whereby a natural “stride” movement of the arm of a user is replicated. The swing arm operates independently from the foot link. The natural “stride” movement of the arm of the user grasping the arm link follows a generally concave motion relative to the ground. The length of the movement of the arm of the user is defined by the user. A different resistive load can be applied on the arm apparatus than on the foot links.
摘要翻译： 椭圆运动装置包括具有第一枢转轴线和纵向轴线的框架，至少一个脚连杆和至少一个摆臂。 脚连接件联接到框架并且被约束以在大致平行于纵向轴线的轨道中移动。 摇臂也联接到框架并且具有往复运动，由此复制了使用者的手臂的自然“跨越”运动。 摆臂独立于脚部连接操作。 抓握手臂连杆的使用者的手臂的自然“大步”运动遵循相对于地面的大致凹入的运动。 用户手臂的移动长度由用户定义。 在手臂装置上可以施加不同的电阻负载，而不是在脚连杆上。
