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: 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. Elliptical trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing elliptical trainers consume excessive floorspace and often lack adjustable pedal motion. The present invention is an improved elliptical exercise machine capable of extended exercise with adjustable pedal motion during operation. Further, the elliptical trainer is more compact with a smaller footprint to conserve floor space. The intermediate portion of a foot support member is guided by a guide member and drives a crank linkage on one end with pedal on the other end. The resulting pedal motion is foot friendly.

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. Elliptical trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing elliptical trainers often produce user problems such as a sensation of dropping off and consume excessive floorspace. The present invention is an improved elliptical exercise machine capable of extended exercise with fewer user problems without the dropping off sensation. Further, the elliptical trainer is more compact with a smaller footprint to conserve floor space. The intermediate portion of a foot support member is guided by a guide member and drives a crank linkage on one end with pedal on the other end. The resulting pedal motion is foot friendly.

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. Elliptical trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing elliptical trainers consume excessive floorspace having shrouds at one or both ends. The present invention is an improved elliptical exercise machine capable of extended exercise with a long stride comparable to existing cross trainers. A shroud which also serves as a step platform is located under the pedals containing the crank, pedal guidance linkage and load resistance. Further, the elliptical trainer is more compact with a smaller footprint to conserve floor space. Handles are connected to the pedals for coordinated arm exercise.

Abstract: The present invention relates to the field of pull/push exercise with an exercise machine that exercises the abdominal, back and leg muscles with the operator recumbent in the face upwards position. Foot contacts follow an arcuate curve path positioned above the recumbent operator. Resistance is provided for each foot contact where the abdominal muscles of the operator pull the lower leg contact towards the operator. Handles are provided to support the arms of the operator. A situp assist device can be used in conjunction with leg pull to exercise the upper abdominals. A leg curl feature is added to the apparatus to allow leg curls. Weight stack resistance is also available.

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 resulting from improper stride length or excessive ankle 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 on one end and drives a control linkage on the other end. The resulting pedal motion is independently adjustable in stride length and ellipse orientation during operation.

A foot support member is guided by a roller on one end and driven by a crank linkage on the other end. The roller is in rolling contact with a curved guide supported by the frame in a manner that allows the curved guide to be repositioned horizontally.

Abstract: A therapeutic head cradle apparatus has a pair of lateral side support members positioned to support the back, front or side of the head. Weight of the head will apply acupressure and shiatsu pressure to various pressure points located in the head area. Elastomeric cushion layers of different densities allow Chinese self-massage while the head is rolled side to side. A means to adjust the distance between the lateral support members is provided. Magnetic therapy and a sound system may also be part of the head cradle apparatus.

Abstract: The present invention relates to the field of knee down push-pull assistive exercise with a compact mobile exercise machine that exercises the abdominal, back and arm muscles in the kneel-prone-kneel movement. The push-pull tractor has a roller in contact with a random supporting surface, a handle offset to the roller axis to support a portion of operator body weight and an energy storage device that returns the tractor towards the starting position. In several embodiments, a wheel is added to the tractor to counteract windup torque energy.

Abstract: A standup exercise apparatus simulates walking and jogging with arm exercise. Foot pedals move with heel and toe curves inclined in opposing directions. The pedals incline with the toe above the heel during the latter portion of forward movement of the foot while the heel inclines above the toe during the latter portion of rearward movement of the foot. Foot pedals move with smooth elliptical motion resulting from a linkage mechanism guiding one foot support member pivot and a rocker link to support the other foot support member pivot. The pedal is is pivoted to one end of the foot support member and articulates the pedal angle separately from the foot support member. Leg joint impact is controlled to be very low as to allow extended exercise without joint soreness. Arm exercise is coordinated with motion of the feet.

Abstract: An exercise apparatus is provided that simulates climbing with coordinated arm exercise. Each pedal is connected to a pair of swing arms that are pivoted above the pedals to guide each pedal alternately downward and rearwards then forward and upwards. Arm exercise is coordinated with each pedal to position the hand proximate the user when the pedal of that body side is forward and upward.

Abstract: A deck suspension system is provided to support the belt of a treadmill with improved shock absorption from foot impact. In the preferred embodiment, the deck is suspended by a pair of cables on either side of the deck which terminate in cushions. A second pair of cables couple the intermediate deck to the framework with cushion adjustment to provide a soft or stiff cushion deck. Deck deformation distributes foot impact to a variety of shock absorption cushions to reduce leg injuries from extended exercise.
