A mogul skiing simulating device having a floating platform riding bearings on crank pins of two crankshaft assemblies while accommodating the changing distance between the two crankshaft pins during their rotation. The leader crankshaft assembly is about 30 to 35 degrees ahead of the follower. The platform is tethered by springs to its central support to maintain the platform in the correct relation to both pairs of crankshaft assemblies. The springs pull from a plastic bushings on each crankshaft pin toward the center of the platform. The tilt of the entire machine is higher in the rear to simulate downhill skiing. Cams may be attached to the front and rear crank journals which act upon the ends of a leaf spring to store and release energy. The crankshafts are turned by and electrically powered nullVnull drive. Railing allows the user to vary hand placement and body position.

An exercise device includes one or more foot supports movable along an arcuate path defined around a point of rotation. The arcuate path is divisible into machine defined user selectable arc segments and the movement of the foot support(s) is limited to the machine defined user selected arc segment. The exercise device can include a frame, a linkage movably engaged with the frame, a foot support movably engaged with the linkage, a crank arm movably engaged with the frame, a motor operative to move the crank arm location with respect to the frame, and a drive linkage movably engaging the linkage.

A leg-exercising device comprises a base, two slide rail seats, two transmission members, and two pedals. The slide rail seats are mounted on the base and are provided therein with a receiving space for disposing the transmission member which is formed of two sprocket wheels and a drive chain running on the two sprocket wheels. The pedals are slidably mounted on the transmission members such that the pedals move up and down along the drive chains of the transmission members.

An elliptical exercise apparatus including a frame, a crank, a pair of guide tracks, and a pair of flexibly resilient foot supports that provide elliptical exercises. Each foot support comprises a leaf spring and a foot engagement pad configured to receive the foot of a user. The foot engagement pads rotate in elliptical paths and the leaf springs flex in varying degree to accommodate for varying forces and gaits of different users. The leaf springs provide upward biasing forces in direct response to sudden and irregular downward forces, thereby flexing to improve the feel of the exercise.

A scooter comprises a base and a handlebar frame. The base is formed of a front support rod, a rear support rod, two foot boards, and two rear wheels. The handlebar frame is fastened with the front end of the front support rod of the base and is provided with a front wheel. A scooter rider stands on the two foot boards such that both hands of the scooter rider hole the handlebar of the handlebar frame. The scooter is initially moved by a push made by one foot against the ground. The scooter is subsequently moved by a series of body twisting motions of the scooter rider.

A compact, elliptical exercise device includes a pair of primary foot links, and a pair of corresponding auxiliary foot links. A first end of each primary foot link is coupled to a pivot axis so as to move in an arcuate path. A second end of each primary foot link is connected to a guide assembly, which constrains it to travel in a reciprocal path of motion. A first end of each auxiliary foot link is coupled to the guide assembly at a connection point spaced from an engagement point at which its respective primary link is connected. Each auxiliary link is slidably supported by a respective one of its primary foot links so that a second end of each auxiliary foot link will travel in a reciprocal path along the primary foot link.

The present invention relates to a low-loaded exercise treadmill comprises a base and a frame. The frame includes a platform and a continuous belt which extends around the platform and is rotatably supported by front and rear rollers by mean of being driven by a motor. The rear end of the frame is fitted with a coupling piece which is pivotably connected to the base while the front end thereof includes a movable supporting bar which is attached to a resilient member at the bottom end thereof. Moreover, the resilient member is located at a proper position of the base. Based on the assembly of the aforementioned members, when the front end of the frame is pressed, the frame is downwardly inclined by means of the simultaneous displacement of the supporting bar. After the loading is reduced gradually, the frame restores itself by means of the extending force of the resilient member so that the frame can make ups and downs movement repetitively.

An exercise machine has a height adjustable front stanchion assembly with a telescoping tube having a quick release locking mechanism and a lower rear stanchion assembly. An inclined monorail is mounted between the stanchion assemblies, and a roller carriage assembly having spool-shaped rollers, is mounted so as to receive the monorail, and roll upon it. Alternately larger roller carriage rollers roll within channels in the monorail. Any of variously tensioned straps is attachable between the roller carriage and either the front stanchion assembly or the rear stanchion assembly to assist or resist the movement of the roller carriage assembly up the inclined monorail. The roller carriage is adapted so that a padded bench assembly and a bicycle seat assembly may be interchangeably rigidly secured to the roller carriage assembly. A rigid bar mounted on the front stanchion retains pull straps grasped by a user to pull the user mounted on the roller carriage up the inclined monorail. Alternately a cable pulley system is attached to the front stanchion and to the roller carriage for pulling the roller carriage. Various handles are attached to the pull straps and pull cables to be grasped by the user in simulating various sports movements while moving the roller carriage. The user may be mounted on the roller carriage or positioned beside the apparatus. The stanchion assemblies are pivotable and may be pivoted parallel to the monorail in a flat configuration and the apparatus transported by rolling on a wheel on one of the stanchions. In the flat configuration, the apparatus may be mounted vertically on a wall bracket and the pulley and cable system used to lift the roller carriage. A bracket and bar are provided to add variously sized weights to the roller carriage. Foot and head supports may also be added to the roller carriage system. An orthogonal foot platform may be attached to the rear stanchion.

An exerciser includes a pair of foot support movably supported on a base, a pair of bars pivotally secured to the base and each having an upper handle, and a pair of links and tracks movably coupled between the base and the bars. The bars each includes a slidable slide coupled to the foot supports. A motor is coupled to the slides for moving the slides along the bars to adjust the foot supports relative to the bars and to adjust the moving stride of the exerciser. A switch is coupled to the motor for actuating the motor while the bars are swung by the users.

A computer controlled exercise machine, particularly adapted for running exercises, virtually eliminates inertial effects and controls resistance to pushing and pulling as a function of instantaneous position in a stroke and/or instantaneous velocity, using the controlled flow of working fluid through computer-controlled valves and sensors of various system parameters in a feedback loop.
