Abstract: An exercise device is provided, having a frame with a first end opposite to a second end and a top portion opposite to a bottom portion, thereby defining four opposing corners. One or more pins may be coupled to the frame between the first end and the second end, the pins adapted to receive weight plates. A bumper may be coupled to each of the four opposing corners. The bumper may be a substantially longitudinal hollow member which may include a plurality of treads on a side opposite to that coupled to the frame. The device may then be supported by two of the bumpers and flipped over to be supported by the other two bumpers. The lifting and flipping of the device provides an exercise which employs many of the major muscles groups of the body. Weight plates may be added or removed to accommodate different users.

Abstract: A gas cooking appliance for connection to a source of gas is provided, having a burner, a cooking surface, a frame adapted to support the burner and the cooking surface, and a first valve in communication with a second valve. The first valve selectively enables flow of gas from the source to the second valve, while the second valve is adapted to provide a variably controlled output to the burner.

Abstract: A safety locking system is used on an exercise device. The locking system includes a first pawl that is mounted to a pawl shaft. The pawl shaft is movably mounted to a lock frame, which can also support a weight collar, adapted to receive weight plates to provide additional resistance to exercise. A second pawl is movably mounted to the lock frame and is connected to the first pawl by way of a spring or other bias mechanism. The lock frame limits the movement of the second pawl so as to provide a bias of the first pawl toward engagement of the pawl to a rack provided with the exercise device. The engagement of either pawl with the rack restricts movement of the lock frame in at least one direction, with gravity. If the bias spring breaks or becomes disengaged from either the first pawl or the second pawl, the second pawl is counterweighted to engage with the rack.

Abstract: An inflatable bladder is used to articulate the spine of a user. A pelvis pad includes a support frame and a pliable cushion positioned thereon. The bladder is supported on the support frame and received by a void in the cushion. In the preferred embodiment the bladder includes two upper portions that extend away from the support frame toward the body of the user. The upper portions of the bladder, or two separate bladders, are cylindrical in shape when expanded. The void in the cushion is also cylindrical in shape and therefore acts to guide the expansion and contraction of the bladders or upper portions of the bladder. The upper portions are preferably positioned eleven inches apart and inflate at least two inches above the support frame. This proximity of the upper portions of the bladder fit the width of the right and left anterior superior illiac spine along the illiac crest of the pelvis. Expansion of the bladder applies a posterior force to the pelvis through the illiac crest and rotates the pelvis.

Abstract: An abdominal exercise machine is provided which includes a seat, which is pivotally linked to a base frame. At least one link includes a handle that can be actuated by a user sitting on the seat. The user presses the handle away from the seat by flexing the trunk muscles of the user. This curls the user's body into a flexed trunk position. As the handle is actuated forward, the linkage arrangement causes the seat to displace upward. This pushes the center of gravity of the user up, thereby doing work and thereby providing resistance to the movement caused by the exercise. The handle may be adjustable in position relative to the link, thereby varying the load used by the user. Foot supports may also be provided either in front of the seat or behind the seat. The foot supports may be mounted to the frame of the seat frame which supports the seat.

Abstract: The disclosed invention is an exercise device being capable of providing aerobic exercise and abdominal muscle conditioning. The device is comprised of an upper frame and a lower frame. The upper frame includes a seat back which supports the upper portion of the torso of a user. The lower frame includes a pelvis support and a bicycle pedaling mechanism. The preferred embodiment includes a linkage system that connects the upper frame to the lower frame. This linkage is capable of providing a translating center of rotation when the upper frame rotates with respect to the lower frame. This is done to follow the body's translating center of rotation during trunk flexion. An alternative to the preferred embodiment includes a arcuate roller attached to the upper frame. This arcuate roller is preferably received by a track on the lower frame, and though preferable, the track is not necessary in order to achieve a translating center of rotation and therefore not necessary to the function of the invention.

Abstract: The disclosed invention is a means of providing an individual with increased ambulatory function through the use of a wheeled chair. The chair includes a lift mechanism, which is comprised of a linkage and an actuation means that can be operated by the user without assistance from another individual. The combination enables a user of compromised physical capabilities, to locomote from one place to another and perform daily tasks that would require bending or reaching. The chair is lightweight and very mobile, thereby minimizing restrictions to the user. The lift mechanism linkage and actuation means minimizes torque on the motor of the actuation means, eliminating current draw spikes which would stall the motor when the battery is low. The lightweight and low friction linkage design maximizes the function of the invention by keeping the battery and actuation means small, thereby reducing the weight and increasing the mobility of the chair.

Abstract: An abdominal exercise device is disclosed. The invention includes a pair of arm portions for the user to grasp, a head rest and support attached thereto, the support being attached to the arm portions, an extension portion extending from each arm portion and a curved radius on the other end thereof. The curved radius being received by a segmented track, the proximal end of the track being fixed to the extension portions such that when a person lies face up between the extension portions with their head on the head rest and pulls down on the arm portions, contracting the abdominal muscles and rolling the curved radius along the track picking up same, the abdominal muscles are worked and the instantaneous center of rotation of the articulating vertebrae are in proper alignment with the instantaneous rotation of the device. This guides the body in a proper sit up movement working the abdominal muscles while the head and neck are constantly supported by the head rest.

Abstract: An exercise device is disclosed that properly optimizes body mechanics to create a safe and effective lower body or combination upper body and lower body workout. The invention is comprised of a pad for the user to lay on and a foot plate to press the user's feet against. A lift arm is provided with handles at the user's sides. As the foot plate is pressed away from the body and the lift arm is pulled from the user's sides upward toward the head. A linkage connected to the arm supporting the foot plate and a linkage connected to the lift arm both work to rotate a center frame, which supports the pad thus doing work by vertically displacing the same and therefore the body weight of the user. Additional resistance can be added by an elastic spring which is situated to apply tension to oppose the rotational movement of the center frame relative to the base frame of the invention.
