Stretching Patents (Class 482/907)
  • Patent number: 5529560
    Abstract: A stretch therapy apparatus is disclosed which provides for enhanced physical fitness as well as rehabilitation and medical treatment. The stretch therapy apparatus includes both a leg stretching component and an arm and back stretching component. The leg stretching component allows the user to easily and safely separate his or her legs by 180.degree. or more using hand crank or motorized mechanisms. Sliding leg deck construction reduces the pressure on the user's knees during leg stretching exercises. The arm and back stretching component allows the user to maintain his or her arms and back muscles in a fully extended position without applying undue force during stretching. The arm and back stretching component includes a platform on which the user is seated and a stretching pole which can be selectively oriented in three dimensional space relative to the user's waist.

  • Patent number: 5520615
    Abstract: A self-assistive shoulder stretching and rotation machine for physical therapy of the shoulder wherein a supine person's forearm is secured to a forearm support that is attached to a horizontal support such that the forearm support may be moved in a 90.degree. arc from vertical in either the left or right direction by the supine person's pulling on a rope. One end of the rope is attached to each side of the forearm support such that a continuous loop is formed. The loop is supported on one side by passing it through pulleys or eyelets attached to a vertical support at one end of the horizontal support. The patient lies in a supine position securing one forearm to the forearm support. When the patient pulls near one end of the rope, the forearm support may be moved in as much as 90.degree. or more to one direction. When the person pulls on the opposite end of the rope, the forearm support is moved back through the vertical position, 90.degree. or more in the opposite direction.

  • Patent number: 5518486
    Abstract: An inexpensive, light-weight, easy to use exercise device which is comprised of a harness having an adjustable flexible, inelastic strap with and adjustable foot loop at one end and a hand grip at the other end. Most exercises are performed using two exercise harnesses. While holding the hand grips and having placed the feet in the foot loops, the user exerts opposing forces between the arms and legs in a variety of exercises while lying down, standing, or sitting. By varying the strength of the forces exerted and the speed of the motion, the user can do isometric, isotonic, stretching, or aerobic exercises.

    Abstract: A stretching machine for performing the Chinese split includes a base, two generally horizontal tracks extending colinearly from the base, a foot platform sliding on each track, and a vertical column with handles. The user stands on the platforms, which travel outward from the base while the split is performed, and maintains balance by holding the handles. The platforms are moved along the tracks by cables fixed to either side of each platform. The cables run over pulleys to a drum mounted in the column, which can be turned by a crank. A novel aspect is a slight angular inclination between the tracks, allowing a deeper split.

  • Patent number: 5125650
    Abstract: An exercise device providing a sling of flexible material forming a cradle supported by a frame so that the cradle is initially taut. The frame is basically a "U" shape fabricated from tube stock. The cradle may be fabricated of canvas with two opposing edges formed as channels into which the frame is inserted. A cross piece completes the closure of the "U" open end, holds the cradle taut and prevents the collapse of the cradle and frame when at upon by the user. The frame by be bent to form a support to hold the cradle in a fixed inclination to the horizontal. A riser and base by be attached to a frame to form a triangle to allow the cradle to be set at a plurality of preselected inclinations.

  • Patent number: 5122106
    Abstract: A stretching apparatus (10) includes a base structure (12) for supporting an individual in supine position. One leg of the individual is disposed within a cradle (14) pivotally mounted on the base structure (12) by a pair of arm assemblies (16a, 16b) which are powered by a hydraulic actuator (20) to rotate about an axis (22) extending generally transversely to the individual's body at a location coinciding with the hip joints of the individual. The cradle (14) includes a foot cup (18) for receiving and supporting the rear and side portions of the individual's foot through which a stretching load is applied to the individual's leg for stretching the muscles, tendons and joint capsules of the lower back, hip, leg, and foot.
