More particularly, an exercise apparatus that exercises the abdominal and back muscles with the lower torso of the operator supported by a moving seat while the upper torso of the operator is supported by a moving seatback. Continuous support of the lower back prevents back strain. The articulation of the seatback is coordinated with the movement of the seat. Adjustment is provided to adjust the rate of movement of the seat relative to the seatback. Handles are provided such that the arm muscles can assist the sit-up or crunch movements.

Abstract: A home exercise device is of greater value when it is capable of multiple functions and can be easily stored when not in use. Lightweight springs are used in place of heavy weight plates to reduce shipping costs and simplify storage. The device also includes a frame that supports a base, providing linear movement of the base relative to the frame. A bar, with spring tension, is coupled to a multi-position lock. This allows the bar to be positioned in a variety of locations relative to the frame and the user, thereby providing a variety of exercises. A head portion is also provided that includes a torsion spring. This spring can be engaged or disengaged from the frame to allow the user to provide spring tension to resist movement of the head portion. The diversity of movable components offers a vast variety of exercises that can be performed on the unit as well as enabling the unit to fold down for storage when not in use.

Abstract: A balancing board allowing for selection of a desired degree of stability is disclosed. The balancing board has a platform and a hemispherical fulcrum slidably mounted to platform and bifurcated into a pair of pivot members. Each pivot member is independently positionable along an underside of the platform opposite of an engagement surface upon which a user positions themselves to practice balancing training techniques. When the pivot members are slid together, the balancing board is freely pivotable about any axis in the plane of the surface on which the pivot members are resting. Conversely, when the pivot members are spaced apart from each other, the balancing board resists pivoting in a direction aligned with the axis along which the pivot members are slidable.

Abstract: A device for support and elevation of the lower extremities. More specifically, the invention is a leg elevator that provides calibrated, adjustable support for the upper leg, the lower leg and the foot. The leg elevator is adjustable to many different positions through the use of three independent adjustment mechanisms. The upper leg portion of the leg elevator can be adapted to accommodate people that have upper legs of various lengths. The height of the lower leg portion is also adjustable, and the relative angular position of the upper and lower leg can be varied from a generally flat position, to a substantially bent position. The invention can be used to provide elevation for either leg separately or for both legs simultaneously. The leg elevator is lightweight, easily disinfected, and can be collapsed to a relatively flat position for ease in transport and storage.

Abstract: A weight-lifter bench is equipped with a removable body support pad having a multiplicity of body support cavities in the pad upper surface. These cavities mate with rear surfaces of the person's head and torso when the person is in a lithotomy position, e.g. when the person is performing a weight-lifting activity using the bench. The cavity surfaces conform to the body surface contours, such that essentially the entire rear surface of the person's torso is in contact with the pad. The pad provides a comfortable support surface, and an enhanced body support action that tends to minimize the potential risk for injury or fatigue.

Abstract: The device is designed to enable the user to perform both abdominal strengthening and back muscle strengthening exercises on the top of a conventional bed. A conventional bed is defined as one with a semi-rigid mattress and a rigid frame. The device attaches and detaches to the described bed easily and provides the means to strengthen both flexor and extensor muscles of the trunk with the dual advantages of maximum convenience and minimum cost. The device is a departure from the previous art in that it enables the user to strengthen the trunk muscles at home without the necessity of cumbersome and expensive equipment.

Abstract: A unique abdominal bench with a pivoting torso section has a number of pivots, rods, and levers that allow the fixed seat section of the abdominal bench to remain a constant distance from the pivoting torso section during an abdominal exercise. The leg section of the abdominal bench pivots towards the abdomen, as does the torso section when the torso is raised. The leg section is pivotably connected to the torso section through a number of rods, pivots and levers such that the gap between the seat and torso section remains the same. A push rod is connected to the pivoting leg brace and is in turn connected to a torso bracket through several guide rods and a dog-leg lever. The push rod, guide rods and the dog-leg lever allow the torso section to remain a constant distance from the fixed seat section.

Abstract: An exercise and rehabilitation chair includes a framework having lower frame members, pivotal front legs, and elongate rear legs. The chair includes a seat assembly having a seat bottom and seat back and upper arms, each upper arm being pivotally coupled at one end to a generally upstanding support arm and at an opposed end to a front leg. Bearing housings pivotally connect corresponding support arms and rear legs and establish a fulcrum about which the seat assembly may rotate. The bearing housings may be slidably positioned longitudinally along corresponding support arms and rear legs using pin fasteners or, alternatively, using motorized gear assemblies. The displacement of the fulcrum relative to a user's hips is adjustable for regulating the resistance of chair operation. A foot assembly is pivotally coupled to the front legs. All pivotal connections correspond anatomically to a user's joints for low joint stress and low-resistance exercise.

Abstract: A low back stretching exercise apparatus which positions the user's knees into a zero to eighty-nine degree angle facing over their head thereby assuring the creation of a safe and gentle longitudinal-convex stretching of the muscles of the human low back. This specific longitudinal-convex stretching action improves low back strength and flexibility and helps to relieve muscle discomfort cause by abnormal stresses on the low back muscles. The unit is height adjusted using the Upright supports (12) & (16) and Tilt brackets (24). The person lies supine between the Stabilizer extensions (20) and places their calves on top of the Deck (10). The angle is adjusted by coupling the Connecting rods (14) with the Angle control bars (22).

Abstract: An exercise with traction device comprising a frame holding a seat above the floor that has a resistance loaded backrest for the purpose of rehabilitating atrophied spinal support muscle through progressive resistance exercise while the spine is under pain alleviating traction. The backrest is resistance loaded for both traction, and extension resistance or flexion resistance. This makes needed exercise for those who are hindered from such therapy by spinal compressive related pain. The exercise resistance is transmitted to the patient via a horizontal axis backrest, and can be weighted either positively for back resistance, or negatively for abdominal resistance, at the same time traction is applied from the backrest suspension system applying resistance to the user attached to it in the direction that decompresses the spine.
