An exercise device includes two foot carriage assemblies. The foot carriage assemblies are operable to support a user's feet on a frame and to travel along a generally lateral path of motion. The foot carriages are operable to engage first and second torque tubes, which in turn participate in resisting the lateral movement of the foot carriages. A lateral striding motion on the exercise device may include a simulation of a motion associated with skating and/or skiing.

Exercise device

A non-impact exercise machine which can be used by people of all ages, requiring no special dexterity or athletic ability to perform and exerting minimal impact on the muscles and joints of the user, providing a light weight, collapsible, and affordable indoor exercise machine for simulating walking. One embodiment of the exercise machine comprises a support structure; and, right and left platforms for standing on by the use's right and left foot respectively in an approximately horizontal position; and, right and left linkage assemblies pivotably disposed on the support structure about a right and left upper pivot axis and the right and left platforms, the platforms movable in a fixed path below the right and left upper pivot axis; and, a resistance system for resisting the movement of the right and left platforms. In one embodyment of the exercise machine the right and left linkage assemblies comprising right and left, first and second members having their first ends pivotably mounted on the support structure about a right and left upper first and second pivot axis respectively and their opposite free ends pivotably mounted to the right and left platforms respectively, the platforms moveable in a fixed path below the right and left upper first and second pivot axis.

Walking exercise machine

An exercising apparatus for simulating skating and skiing motion in which outward and opposite unilateral movement of the user's feet ultimately drives a momentum storage member which can be a flywheel. The apparatus has a base for supporting a track having left and right distal ends. The track positions and restrains foot carriages to approximately horizontal movement. The foot carriages support the user's feet so that when the user's left foot extends outwardly and to the left of user's body the left carriage moves towards the left distal end of the track, and when the user's right foot extends outwardly and to the right of user's body the right carriage moves towards the right distal end of the track. A driven pulley is supported by the base and drives the momentum storage member. The apparatus has a first subassembly having unilaterally acting first engaging member and first transmission, and a second subassembly having unilaterally acting second engaging member and second transmission. The first subassembly drives the driven pulley in a drive direction when the left carriage moves towards the left distal end and does not drive the driven pulley when the left carriage moves towards the right distal end. The second subassembly drives the driven pulley in the drive direction when the right carriage moves towards the right distal end and does not drive the driven pulley when the right carriage moves towards the left distal end. The momentum storage member provides resistance to outward movement of the carriages. A variable braking force can be applied to the momentum storage member.

Exercising apparatus

A shock-free exercising machine, which can be used by the young and elderly, the small and large structured person, and the inexperienced and experienced exerciser for both aerobic and anaerobic exercise, that provides a rhythmic fluid motion to the body of the user and particularly to the legs, pelvis and spine which is completely free of shock and impact stress on the joints, bones and muscles in which, at all times, the user remains in an upright standing position. In one embodiment the exercise simulates clinging motion of the user's legs with synchronized push-pull motion of the user's arms. On one embodiment the exercising machine comprises a base member; a vertical frame member fixedly attached there, right and left lower levers pivotally mounted on the lower part of the vertical member, the free ends the levers for standing on; right and left upper levers pivotally mounted on the upper part of the vertical member; right and left tie rods pivotally mounted at the upper distal ends thereof to the right and left upper levers, respectively, and pivotally mounted at the lower distal ends thereof to the right and left lower levers, respectively; rocker arm assembly for synchronizing the movement of the lower levers so that when one lower lever moves downwardly the other one moves upwardly; and shock-free resistance system for resisting the movement of at least one of the levers.

Shock-free aerobic and anaerobic exercising machine for use in the

Physical exerciser

An exercise apparatus which simulates stair climbing, is adjustable to achieve various levels of difficulty and adjustable to accommodate individuals of all heights. The exercise apparatus has a support structure, left and right foot levers pivotally connected to the support structure, a rotatable shaft rotatably attached to the support structure, and left and right clutches drivingly connected to the rotatable shaft. The left and right clutches independently drive the rotatable shaft in a drive-rotational direction when either of the clutches is rotated in the drive-rotational direction. Each clutch overrides the rotatable shaft when rotated in the counter drive-rotational direction. Pulleys or sprockets are mounted on each of the clutches. A rope or chain drivingly engages the pulleys or sprockets and causes their rotation when the foot levers are moved. A worm gear, which is driven by the rotatable shaft, is part of a resistance assembly mounted on the support structure. The resistance assembly contains a worm driven by the worm gear, a flywheel mounted on the worm, and braking device for braking the flywheel. The worm gear assembly and flywheel imparts a smooth, dynamic fluid-like operation to the movement of the foot levers. In one embodiment the foot levers operate independently of each other. In another embodiment the foot levers are synchronized. In still another embodiment the foot lever operation can be easily converted back and forth between independent and synchronized motion thereby allowing for variation in exercising routines.

Exercise apparatus

Low impact stair climbing exercise apparatus

An aerobic conditioning apparatus for use by a trainee in simultaneously exercising the upper and lower body in a smooth shock-free manner substantially simulating movement of the arms and legs during swimming. The apparatus includes a supporting frame, first and second foot supporting assemblies mounted on the supporting frame for controlling the movement of the right and left feet of the user respectively to an oscillatory motion along first and second paths between first forward positions and a second rearward position, first and second hand engaging assemblies mounted on the supporting frame for controlling the movement of the right and left hands of the user respectively to an oscillatory motion along paths between a first upraised position and a second lowered position, and synchronizing mechanisms mounted on the supporting frame for causing synchronous movement of the foot engaging assemblies and the hand engaging assemblies.
