Abstract: A Gravity Sled Exercise Machine wherein leveraged body forces act to overcome gravity to move a two piece body sled and client upward, along biangular support rails, from a horizontal to a vertical orientation. To support the torso during the change in spatial orientation, a fixed angle sled seat reciprocates in lineal motion on the lower of two differentially inclined rails. In concurrent action, the lower section of a back rest pivots on an axle at the rear of the seat, while its upper end rides via a pivot guide on the upper, more vertically inclined rail. That kinetic linkage produces a curvilinear motion that constantly repositions the sled and introduces variable resistance to the exercise cycle.An arrangement of handrings, lines and pulleys provides the leverage for arm and upper body exercises, while Class I and II levers enable leg and lower body exercises. A flexible coupling attaches a leg lever assembly to either the static lower rail or to the moving sled seat.

Abstract: A multi-station exercise machine has a movable subframe on which a user sits while performing various exercises. The subframe is pivotally attached to a stationery frame and is supported by a lever arm that is also pivotally attached to the stationery frame. The pivot arms coupling the subframe to the stationery frame bear against a carriage that is movable located on the lever arm. A cable and pulley system couples the lever arm to the various operable members of the apparatus so that a selectable ratio of the weight of the subframe, including the user, is communicated as exercise resistance. The amount of weight that is coupled to the operable members is selected by positioning the carriage along the lever arm. This adjustment also varies the height to which the subframe is lifted by the exercise stroke and hence the effort that must be exerted by the user.

Abstract: An exercise apparatus (10) includes a hydraulic resistance member (50) with a single sided hydraulic cylinder (53) for pumping fluid through a fluid circuit (80). Lever members (31, 32) pivot in a common plane and extend outward to embrace the hydraulic resistance member (50) between them. Stop members (221,223) limit movement of the lever members (31, 32), and biasing member (230) biases 10 the lever members (31,32) apart. An immobilizing member (40) may selectively immobilize either one of the lever members (31, 32). An extension arm (17) supports an exercise member (16) which may move along an exercise stroke only by pumping cylinder (53). The fluid circuit (80) allows fluid to flow from the cylinder (53) only when pressure in the cylinder (53) exceeds a selected pressure corresponding to a selected exercising force determined in accordance with the position of the member (16) along the exercise stroke by a control linkage (100). During the return stroke, no exercising force is required.

Abstract: An attachment for a weight stack type exercise machine to pull the weight stack down while it is being lowered, so that the eccentric exercise force required to lower the stack is greater than the concentric exercise force required to raise it. Such asymmetric exercise forces more closely match muscle strengths, which are normally greater for eccentric exercise than for concentric exercise. The attachment has an electric motor and a control unit including a keypad, a display and a microcontroller. The motor is coupled to the weight stack by an eccentric force control cable. The keypad allows the user to select the amount of force added during the eccentric phase of exercise, when the weight stack is moving down and part of a lifting cable connected to a handle or engageable member on the weight stack type machine is moving in. A sensor enables the controller to determine whether the weight stack is moving up or down.

Abstract: A device for therapeutically treating a desired region of a patient's body with a nonambient temperature fluid includes a fluid feed reservoir, a fluid collection reservoir, and a fluid flowpath therebetween. The flowpath is made up of a heat transfer pad placed over the desired treatment region, an inlet line leading from the feed reservoir to the pad, and an outlet line leading from the pad to the collection reservoir. In operation, the feed reservoir is charged with a nonambient temperature fluid and maintained at a height substantially greater than the height of the collection reservoir to provide a fluid head sufficient to transport the fluid from the feed reservoir to the collection reservoir across the flowpath. In so doing, the pad provides therapeutic treatment to the region of the body that it contacts. The temperature of the pad is controlled by maintaining a height differential between the fluid levels in the feed reservoir and the collection reservoir.
