An exercise and rehabilitation apparatus for exercising an extremity of a user. The apparatus includes a flywheel having a first side and a second side with a channel in the first side. The channel has a top edge near a planer surface of the first side. A lever, such as a pedal or handle, is adjustable in position and combined with an adjustment member. The adjustment member is movable within the channel between first and second positions. However, the adjustment member cannot be removed from the channel through a slot along the top edge. A locking pin, biased in an extended position, is combined with the adjustment member and is movable between the extended position and a retracted position. The flywheel includes a plurality of openings adapted to receive the locking pin in the extended position in order to secure the adjustment member at a particular location within the channel.

A stationary exercise machine may include reciprocating hand members, such as handles, and/or reciprocating foot members, such as foot pedals. The reciprocating hand members may be operative to apply a first moment to a crankshaft, and the reciprocating foot members may be operative to apply a second moment to the crankshaft. The second moment may be different than the first moment. The reciprocating foot members may cause a user's feet to move along a closed loop path that is substantially inclined, such that the user's foot motion simulates a climbing motion more than a flat walking or running motion. The reciprocating hand members may be configured to move in coordination with the foot members via a linkage operatively coupling the hand members with the foot members. A resistance mechanism may apply resistance to crankshaft rotation, and the resistance mechanism may be adjustable while the user is using the machine.

An exercise machine which provides a continuously variable exercise path for a user, based on the use of a first crank which rotates about a primary axis, and a second crank which is user-rotated about a second axis on the first crank and which is linked to a stationary cog so that the first and the second cranks counter-rotate.

This invention discloses a climbing machine. Without being limited by the structure of the climbing assembly, the upper limbs and the lower limbs of the user can have different moving paths. In addition, the climbing machine also has the advantages of rapid response, wide range of resistance adjustment, and smooth operation.

An exercise apparatus includes a frame adapted to be rested on a floor surface, a crank mechanism that has two cranks mounted on the frame, two swing members pivotally mounted on the frame, two connecting assemblies, and a guiding device. Each of the two connecting assemblies has a plurality of connecting rods connecting the respective crank and the respective swing member. The two connecting assemblies define two pedal portions for supporting a user's feet, and up-and-down movement of the pedal portions causes rotation of the two cranks along a circular path. The guiding device is configured to connect the two swing members for guiding swing movement of the two swing members within a predetermined swing range. The predetermined swing range is adjustable so as to provide various exercise paths.

Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine.

A stationary exercise device having variable footpaths is disclosed. The exercise device includes a frame, a pair of supporting members that have a first end to rotate about an axis and a second end to move along a reciprocating path, a pair of pedals joined to the supporting members, and a guider assembly for adjusting an incline angle of the reciprocating path.

A linkage assembly movably supports a seat relative to a frame for movement of the seat through an elliptical path of motion. The elliptical path may be selectively adjusted by repositioning linkage assembly components relative to one another. At least some of the elliptical paths have a length greater than a diameter defined by a crank that rotates in conjunction with the elliptical motion. Handles are also movably supported by the linkage assembly for movement through an arcuate path of motion. The handle path may be selectively adjusted in conjunction with adjustment of the seat path or independent of adjustment of the seat path.

A climbing machine includes a base; two sets of two inclined parallel rails wherein each rail has one end secured to a joining portion of a handlebar and the base and the other end rested on the ground; two pedals slidably mounted on the rails respectively; two spaced first wheels mounted forwardly of the rails; a magnetic resistance controlling device configured to add difficulty to motion and including a conductive disc, a curved groove member releasably secured to an edge of the conductive disc, magnetic elements disposed on two inner walls of the curved groove member, an axle disposed in the base, and at least one roller rotatably mounted on the axle; and at least one first rope each extending from the first wheel to wind around the roller prior to attaching to the pedal. In response to rotating the roller, the conductive disc rotates.

An apparatus and method for physical therapy includes a base structure, a roller table positioned on the base structure including a plurality of free motion rollers, at least one motor and/or and at least one air compressor connected to the base structure, a plurality of powered rollers or a contact plate located within the base structure being in contact with the plurality of free motion rollers, at least one pneumatic block with a pneumatic piston connected to the at least one air compressor and being configured to raise and lower the power rollers and/or the contact plate, a load cell in communication with the apparatus being configured to measure and record a patient's response to the transition of the roller table and/or the contact plate, and a programmable logic controller.
