Abstract: An exercise apparatus has left and right foot skates which are constrained to move back and forth in reciprocal fashion. Left and right foot platforms are movably mounted on respective foot skates and constrained to move up and down in reciprocal fashion. The apparatus may be operated in different modes of operation, including a first mode, wherein the foot skates are free to move back and forth and the foot platforms are free to move up and down; a second mode, wherein the foot platforms are free to move up and down, but the foot skates are locked (or biased) against movement; and a third mode, wherein the foot skates are free to move back and forth, but the foot platforms are locked (or biased) against movement. Resistance may be provided to back and forth movement of the foot skates and/or up and down movement of the foot platforms.

Abstract: A flexible exercise apparatus is provided which enables the user to exercise both upper and lower body muscle groups. The apparatus includes a frame structure means, an upper body engagement means, and a lower body engagement means. The upper and lower body engagement means are coupled to the frame structure means. The user operates the apparatus while in a generally lying position. The user may push and pull backward and forward upon two handle members with their hands, which are part of the hand engagement means. This motion is transferred into a pivoting motion of the lower body engagement means, which is engaged by the legs of the user. The lower body of the user may be used to provide resistance to the upper body of the user. Conversely, the user may pivot the lower body engagement means with their legs, and move said handle members of said upper body engagement means in the foward and backward directions. The upper body of the user may be used to provide resistance to the lower body of the user.

Abstract: A bicycle includes a frame and a wheel rotatably mounted in relation thereto. The wheel is drivable by two pedal devices including pedal-equipped arms. The two pedal devices are individually mounted in different bearings and connected to the wheel via two different transmissions, which separately co-operates with a mechanical clutch. The clutch includes a dog being movable to and from opposite shoulder surfaces of which a first one guarantees driving the wheel when the dog, in an active state, is pressed against the first shoulder, and the second shoulder gives rise to noise when the dog, in an inactive state, collides with the second shoulder.

Abstract: An improved stationary exercise cycle comprised of a handlebar and a saddle respectively installed at two extremities of a swing rod, a base support rod to which the anterior extremity of the swing rod is hinged, a push arm extending downward from the posterior extremity of the swing rod, and a guide wheel disposed at the lower end of the push arm that contacts a polygonal drive wheel over the axle of the bottom bracket shell on the base. When a person treadles the pedals and thereby rotates the polygonal drive wheel, the guide wheel contacts the polygonal drive wheel and the support rod on the base serves as a fulcrum on which the swing rod pivots upward and downward in a seesaw fashion, with the handlebar and the saddle at the two extremities of the swing rod alternately rising and falling such that the user not only strengthens both legs, but also invigorates the arms and entire body, thereby providing for a massage-like yet effective and comprehensive physical exercise routine.

Abstract: A multiple rigid bar mechanism serving as an exercise machine which may be characterized as providing a motion path along a closed curve. In the simplest embodiment, the mechanism comprises a motion bar rotatably connected to a flywheel and a trunnion element. The flywheel is rotatably secured to the machine frame about a flywheel base joint, and is eccentrically connected to the motion bar at a flywheel motion bar first joint. Upon input force from the machine operator at a motion bar force input region, the motion bar will be caused to pivot about a motion bar trunnion region thus effecting the motion bar first joint to translate at an eccentric radius about the flywheel or crank rotational axis. The mechanism may be used to exercise the operators upper and/or lower body, and may be described as having a reciprocating type of resistive motion with inertial characteristics of a flywheel.

Abstract: A rotatable exercise bar having a pair of the handgrips that are longitudinally and transversely offset from each other is provided with adjustment mechanisms that allow both the transverse and longitudinal distances of separation between the handgrips to be varied according to the comfort of the user. The adjustment mechanisms of the rotatable exercise bar permit customization of the exercise bar to accommodate most different physiques, arm lengths, muscles strengths and coordination capabilities among different individuals. Adjustment of the longitudinal distance of separation between the handgrips is provided by mounting the handgrips slidably upon the longitudinally and transversely separated handgrip sections of the bar. Releaseable clamps are located at both ends of each handgrip. Each handgrip may thereby be selectively positioned at a desired location along its associated handgrip section of the bar.

Abstract: An exercise bicycle is composed of a bicycle frame, a vibration device, a driving device, and a clutch device. The bicycle frame is provided with a pedal device. The vibration device and the pedal device are driven by the driving device such that the pedal device can be temporarily disabled by the clutch device. The vibration device is capable of actuating the bicycle frame to vibrate so as to massage the body of a user of the exercise bicycle while the user is engaged in the pedalling exercise. The exercise bicycle can be used as a body massaging machine by actuating the clutch device to disable the pedal device.

Abstract: The present invention relates to a standup exercise apparatus that simulates walking, jogging and climbing with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet.Cross trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing machines often produce user problems such as excessive foot articulation. The present invention is an improved elliptical exercise machine capable of extended exercise with fewer user problems. Further, the cross trainer is adjustable to vary the motion of the elliptical stride from walking to climbing.A foot support member is guided by a guide linkage on one end and driven by a crank linkage on the other end. The resulting pedal motion has less severe pedal angles than a simple crank cross trainer. Handles are coupled to the guide linkage for coordinated arm exercise.

Abstract: A compact standup exercise apparatus simulates walking and jogging with arm exercise. Elongate foot pedals move with a back and forth elliptical movement while the pedals incline. Several foot positions are provided on the elongate pedals. Arm exercise is coordinated with the motion of the foot pedals. An adjustable connector link is provided to relocate the arm exercise for different foot positions on the elongate pedals. Leg joint impact is controlled to be very low as to allow extended exercise without joint soreness.

Abstract: A portable exercise device is described having a first longitudinal member, a second longitudinal member adapted to be grasped by a user and a third longitudinal member. The second member is attached to one end of a first arm at a substantially perpendicular angle, the first arm being attached the first member at a substantially perpendicular angle. The first and third longitudinal members are adapted to bear comfortably against a user's body. The third member is attached to one end of a second arm at a substantially perpendicular angle, the second arm being attached to the first member at a substantially perpendicular angle. At least one of the arms is pivotally mounted to the first member and a spring is provided for resisting any change in the relative position between the first and second arms.

Abstract: In an exercising apparatus for supporting a bicycle, a pivotally mounted member connects to a rear axle of the bike to constrain movement of the axle about the pivot point of the support member. A support roller, located on the horizontally opposite side of the rear axle as is the pivot point, cooperates with the support member to support the rear wheel. A flywheel and variable load means are connected to the roller to simulate the inertia and variable load experienced during the riding of a real bicycle. Preferably, a front fork support connects to the front fork of a bicycle and has an adjustable feature which can change the elevation of the bicycle frame. The front fork support is inclined and connected to this rear axle support member so that when a rider of a bicycle connected to the apparatus leans toward or shifts his weight toward the front fork support, the front fork support bends and the rear tire of the bicycle pivots toward the roller to maintain frictional contact between the tire and roller.

Abstract: The present invention pertains to an apparatus for exercising. The exercise apparatus is comprised of a first horizontal member and a second horizontal member in spatial relationship to the first horizontal member. A horizontal cross member is disposed anteriorly to the first and second horizontal members and is essentially perpendicular thereto. A platform supports the first horizontal member, the second horizontal member, and the horizontal cross member. The platform has a first vertical axis which extends through a first location where the first horizontal member is supported by the platform, and a second vertical axis extending through a second location where the second horizontal member is supported by the platform. The platform also defines an open region which extends between the first and second horizontal members and below the horizontal cross member.

Abstract: A conventional bicycle is mounted and restrained for exercise on a treadmill frame.

Abstract: A power skating exercise device includes a pair of endless guide tracks, each of which have a power section and a return section and a pedal for each guide track. The pedal is mounted on a follower which is slidably mounted in one of the guide tracks. The follower is proportioned to pass freely along the return section. Drag is applied to the follower as it is driven along the drive section to resist the movement of the follower. A support frame is provided for supporting the user in a forwardly inclined semi-prone position which corresponds to the position assumed by a skater when accelerating forwardly.

Abstract: The invention includes a conventional exercise bicycle with foot pedals, a chain drive system and a flywheel. Rotating with the flywheel is a first gear which is in mesh with a second larger gear. Located on the face of the second gear, but offset form the center of the gear, is an eccentric which supports reciprocating arms. Movement of the reciprocating arms by the exerciser causes rotation of the second and first gears and, consequently, the flywheel. The foot pedals or the reciprocating arms may independently operate the flywheel.
