A linear motion synchronizing mechanism is for an exercise assembly having elongated first and second rocker arms that pivot with respect to each other about a first pivot axis. A first roller is retained on a first roller supporting member and a second roller retained on a opposing second roller supporting member. The first and second rollers are configured to roll along opposite sides of a linear frame member as the body moves in the first and second directions. A tensioner applies a tensioning force between the first roller supporting member and second roller supporting member so that compression forces are applied on the first and second rollers. The compression forces cause the first and second rollers to mechanically resist pivoting of the first and second rocker arms with respect to each other about the first pivot axis.

Linear motion synchronizing mechanism and exercise assemblies having linear motion synchronizing mechanism

An exercise assembly comprises elongated first and second rocker arms that pivot with respect to each other in a scissors-like motion about a first pivot axis. A slider has a slider body that slides along a linear axis extending through and perpendicular to the first pivot axis. A linkage pivotally couples the first and second rocker arms to the slider body. Pivoting the first and second rocker arms with respect to each other causes the slider body to slide in a first direction along the linear axis. Opposite pivoting of the first and second rocker arms with respect to each other causes the slider body to slide in an opposite, second direction along the linear axis.

Exercise assemblies having linear motion synchronizing mechanism

An exercise apparatus to simulate climbing is described that includes such features as arm handles that move in synchronism with the motion of foot pedals to provide a total body workout; side handrails; a mounting step; linear foot movement at a simulated climbing angle; a three point support structure using a vertical support column; pedal track covers; a mechanism to provide constant resistance to pedal motion; and pedal impact absorption.

Climber appliance

Climber mechanism

A simulated stair climbing-type exercise apparatus is provided having a frame, a resistance member, a transmission, a drive belt, a right pedal assembly, a left pedal assembly and a track mounted to the frame to provide a user with a vertically reciprocating exercise movement. The right pedal assembly, operating independently of the left pedal assembly, oscillates between an upper position at rest and a lower position under the weight of the user. The left pedal assembly, operating independently of the right pedal assembly, oscillates between an upper position at rest and a lower position under the weight of the user. The pedal assemblies remain parallel to a support surface throughout their entire range of motion, as the pedal assemblies travel from their upper position to their lower position on the tracks which can be either linear or curved.

Stairclimber apparatus pedal mechanism

A simulated stair climbing-type exercise apparatus is provided having a frame, a resistance member, a transmission, a drive belt, a right pedal assembly, a left pedal assembly and a track mounted to the frame to provide a user with a vertically reciprocating exercise movement. The right pedal assembly, operating independently of the left pedal assembly and having a set of rollers engaged with the track, oscillates between an upper position at rest and a lower position under the weight of the user. The left pedal assembly, operating independently of the right pedal assembly and having a set of rollers engaged with the track, oscillates between an upper position at rest and a lower position under the weight of the user. The pedal assemblies remain parallel to a support surface throughout their entire range of motion, as the pedal assemblies travel from their upper position to their lower position.

An exercise apparatus includes a frame that is adapted for placement on the floor, a pivot axis supported by the frame, a pedal bar which has first and second ends, a pedal that is secured to the pedal bar, an ellipse generator, and a track. The ellipse generator is secured to both the pivot axis and to the first end of the pedal bar such that the first end of said pedal bar moves in an elliptical path around the pivot axis. The track is secured to the frame and engages the second end of said pedal bar such that the second end moves in a linear reciprocating path as the first end of the pedal bar moves in the elliptical path around said pivot axis. Consequently, the pedal also moves in a generally elliptical path. As the pedal moves in its elliptical path, the angular orientation of the pedal, relative to a fixed, horizontal plane, such as the floor, varies in a manner that simulates a natural heel to toe flexure. The apparatus can also include a resistance member, a data input member, and a control member. The resistance member applies a resistive force to the pedal. The data input means permits the user to input control signals. The control means responds to the input control member to control the resistance member and apply a braking force to the pedal. In addition, the exercise apparatus can include an arm handle and an arm handle coupling assembly that couples the arm handle to the pedal such that the arm handle moves in synchronism with the pedal, and in some cases out of phase.
