Abstract: A portable medical training manikin with a hollow torso body with a chest plate having slotted openings provided to enable realistic flexing of the chest plate along hinges engaged with a chest compression piston. The torso body has a realistic skin covering the torso and interconnected at a hinge. A chest compression piston supports and resists chest compressions performed by a user. The chest compression piston is engaged with the central chest plate of the torso body by a quick release mechanism having detent locks for securing the piston engaged with the chest plate. A two-piece tiltable head configuration enables detachment of the back half of the head piece, and inversion for nested stacking within the front half head piece. The hollow torso body is likewise configured for convenient stacking, including the compression pistons, in a carrying container.

Abstract: An elliptical exercise machine and methods for using the machine where the horizontal length of the stride of the ellipse can be adjusted by the user without the user having to alter the vertical dimension of the ellipse by an equivalent amount. The machine provides for alteration due to the interaction of two arms via a coupler where distance from a rotational axis to the coupler may be adjusted The machine may allow for this adjustment to occur during the performance of an exercise routine.

Abstract: An elliptical exercise machine and methods for using the machine where the horizontal length of the stride of the ellipse can be adjusted by the user without the user having to alter the vertical dimension of the ellipse by an equivalent amount. The machine provides for alteration from a rocker bar's distal end following a cam track, whose position is adjustable. The machine may allow for this adjustment to occur during the performance of an exercise routine.

Abstract: An elliptical exercise machine and methods for using the machine where the horizontal length of the stride of the ellipse can be adjusted by the user without the user having to alter the vertical dimension of the ellipse by an equivalent amount. The machine provides for alteration using an inverted pendulum arm which is driven by rotation of a rail and which in turn drives a footskate on the rail. The position for the driving of the inverted pendulum arm by the rail and the driving of the footskate by the inverted pendulum arm are adjustable relative to each other so as to provide for multiple different stride lengths in exercising. The machine may allow for this adjustment to occur during the performance of an exercise routine.

Abstract: A treadmill of the present invention comprises a base, a pair of spaced rollers journalled in the base, an endless belt, a longitudinally extending support deck, and a deck spacer. One of the rollers constitutes a rear roller and the other roller constitutes a forward roller spaced forward of the rear roller. The endless belt is entrained around the rollers and includes an upper reach that extends longitudinally between the rollers. The upper reach of the belt is adapted to enable a user to walk or run thereon. The support deck is connected to the base and is operatively engageable with an underside of the upper reach of the endless belt for supporting the upper reach. The deck spacer includes a deck engaging portion adapted for operatively engaging the support deck. The deck engaging portion is adapted to operate in at least a first condition and a second condition.

Abstract: A motorless treadmill for exercising the upper body and lower body of a user. Displacement of an upper-body exercise mechanism such as a pair of reciprocating arm members rotates a drive roller. The drive roller is coupled to an endless belt, and a transmission system links the drive roller to the upper body exercise mechanism such that arm movements are translated into belt rotation. In one embodiment, pulleys are used as the transmission system to transmit the energy from the movement of the arm members to the belt. A flywheel may be added to store energy to smooth the belt rotation.

Abstract: This disclosure relates to a rower-type exerciser comprising a support base, a seat, and pivot links connecting the seat with the base to produce a glider-type rocking motion. A resistance device is connected between the parts to resist or restrain the rocking motion. Force arms are attached to the links to enable an operator on the seat to induce the rocking motion, and a foot brace is attached to the support base to enable the operator to brace the feet and/or push or pull forward with footstraps in place against the brace to further induce the rocking motion. The user can emphasize force contributions of either the user's top extremities or lower extremities to the rocking motion inducing forces.

Abstract: An exercise rowing machine has a frame structure with a center track rail, front and rear cross-members supporting the track rail, and a U-frame connected to the track rail and the front cross-member. The front cross-member is a one-piece molded part providing a seat for the track rail, saddles for a pivot shaft for foot plates, clevises for pivotal connection to hydraulic cylinder units which are pivotally connected to rowing arms in turn pivotally connected to the U-frame, sockets for receiving the U-frame, and supports for front transport wheels.
