An exercise apparatus links rotation of left and right cranks to elliptical movement of left and right foot supporting members. The foot supporting members include left and right foot platforms that travel through space defined between the left and right cranks. Rollers on the cranks allow the foot supporting members to translate relative to the cranks, and amplified drawbar/rocket link arrangements determine the extent of the translation.

In a simulated stairclimbing apparatus having a pair of pedal members rotatably attached at one end to the frame of the apparatus and having a foot pedal rotatably attached to the other end of each pedal member, a pulley is attached to each pedal and another pair of pulleys is attached to the frame where flexible members such as cables are engaged with the pedal and frame pulleys for each pedal member so as to keep the pedals level through the vertical motion of the pedals. In another arrangemen...

A fixed safety handle of an elliptical cross trainer includes a fixed safety handle disposed near the top of a primary upright frame of an elliptical cross trainer, extended in direction of the operator, and bent in U-shape. The fixed safety handle includes a first holding member extending downwardly from both ends of the fixed safety handle and a second holding member extending laterally from the first holding member in direction to the outside such that the second holding member is located bey...

An exercise device includes a right and a left belt part arranged in connection with the right and the left pedal part. The belt parts are arranged to travel as an endless loop around sheaves. A right and a left rod part, each has a first end and a second end. The right footrest is fastened to the right belt part and the left footrest to the left belt part. The first end of the right rod part is fastened to the right belt part and the second end is pivoted to the frame structure. The first end o...

An improved lift apparatus for use in a treadmill having a support base and a treadbase is disclosed. The lift apparatus includes a lift motor assembly linked to the support base and to a cam. The first cam can be attached to a torsion bar linked to the support base. An incline link bar is linked to the first cam and to the treadbase. The force generated by the motor assembly is efficiently translated from the cam to the treadbase, thereby inclining the treadbase.

A foldable mechanism for treadmills includes two respective foldable sets and an operation bar is connected to the two foldable sets. Each foldable set has an operation member fixed to the upright frame corresponding thereto and the operation member has a groove defined in a side thereof. A periphery defining the groove includes multiple recesses. Two end plates each have a first end fixed to one of two ends of the operation bar and the other end of each end plate is pivotably connected to the f...

A step exerciser has a base, a pedal element pivotally mounted on the base, and having a first female hollow shank pivotally mounted on the base, two pedals mounted on two opposed sides of and pivoted relative to the first female hollow shank, an interconnection element connected between the pedals and the first female hollow shank, and a damping element provided on the pedal element. Hence, the step exerciser can provide a user with various exercise effects.

A modified fitness equipment of three-dimensional sway structure. The basement is provided with a pedal while a crosswise movable pipe is mounted at the bottom of the pedal. And, a dragging member is installed to provide a preset resistance to pedal during treading movement. Also, one end of the movable pipe is connected to the exterior of a shaft lever at one side of a vertical pivotal pipe over the basement. Thus, a movable end with horizontal spin can take shape at the other end of the movabl...

A shield apparatus to cover and protect the exposed rear roller on exercise treadmills is provided. The shield takes the form of a "C"-shaped guard that encompasses the rear roller across its entire width. The invention fastens to the main side rails of the treadmill by the use of a fastener such as self-tapping sheet metal screws. The guard is provided in two pieces and uses a slip arrangement to accommodate treadmills of differing width.

The invention relates to office and work furniture with a table top or work bench top and a support frame supporting the top, where+in the support frame is supported on the floor by at least two legs or at least one support surface. A treadmill exercising device in the form of a moveable continuous conveyor belt is stored in its rest position inside the three-dimensional space of the treadmill exercising device, from which rest position the device can be moved or tilted into the operating positi...
