Abstract
Abstract A physical-rehabilitation and exercise apparatus designed to aid in rehabilitating disabled individuals, particularly stroke victims who have been partially paralyzed. The apparatus is defined by a frame structure having an adjustable seat which incorporates individually operable right and left arm-control actuators, and right and left leg-control actuators. The arm-control actuators together with the leg-control actuators are adjustably slidable so as to provide a reciprocal longitudinal action which is determined by the proper selection of valves within a hydraulic system that includes a plurality of cylinders, each being integrally formed as part of the respective arm and leg control actuators, whereby a series of sequential operations can be selected by the user to provide the necessary movement for exercising the disabled limb or limbs.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A physical-rehabilitation and exercising apparatus for the handicapped and disabled individual, wherein the active limb members of the user assist in rehabilitating and exercising the inactive limb members, said apparatus comprising: a frame structure; a chair-support means mounted to said frame structure and adapted to support the user thereof while operating said apparatus; arm-control means slidably mounted to said frame structure for reciprocal horizontal movement along said frame; leg-control means slidably mounted to said frame structure for reciprocal horizontal movement along said frame, said leg-control means being positioned below said arm-control means; and wherein said arm-control means and said leg-control means are adapted to be reciprocally actuated in an individual selective manner in accordance with the user's requirements; means for selectively controlling the reciprocating action of said arm and leg control means.
Claim 2
Dependent Claim
132 words
A physical-rehabilitation and exercising apparatus for the handicapped and disabled individual, wherein the active limb members of the user assist in rehabilitating and exercising the inactive limb members, said apparatus comprising: a frame structure; a chair-support means mounted to said frame structure and adapted to support the user thereof while operating said apparatus; arm-control means slidably mounted to said frame structure for reciprocal horizontal movement along said frame; leg-control means slidably mounted to said frame structure for reciprocal horizontal movement along said frame, said leg-control means being positioned below said arm-control means; and wherein said arm-control means and said leg-control means are adapted to be reciprocally actuated in an individual selective manner in accordance with the user's requirements; means for selectively controlling the reciprocating action of said arm and leg control means.
Claim 3
Dependent Claim
31 words
An apparatus as recited in claim 1, wherein: said arm-control means includes a right-arm-control actuator and a left-arm-control actuator; and said leg-control means includes a right-leg-control actuator and a left-leg-control actuator.
Claim 4
Dependent Claim
96 words
An apparatus as recited in claim 2, wherein said means for controlling the reciprocating action of said control actuators comprises a hydraulic system including: a first hydraulic cylinder motor connected to said right-arm-control actuator; a second hydraulic cylinder motor connected to said left-arm-control actuator; a third hydraulic cylinder motor connected to said right-leg-control actuator; and a fourth hydraulic cylinder motor connected to said left-leg-control actuator; and a plurality of valves adapted to be selectively arranged to establish predetermined sequences of operation for said hydraulic cylinder motor, whereby said control actuators are activated in corresponding sequential movements.
Claim 5
Dependent Claim
83 words
An apparatus as recited in claim 3, wherein each of said right and left arm-control actuators comprises: an adjustable handle-bar member on which the user's hand is placed when he or she is in a seated position; reciprocal carriage means forming part of said frame structure, and wherein said handle-bar member is adjustably mounted thereto, each of said carriage means being connected to respective hydraulic cylinder motors; and means for adjusting said handle bar rotationally and longitudinally with respect to said carriage means.
Claim 6
Dependent Claim
66 words
An apparatus as recited in claim 4, wherein each of said right and left leg-control actuators comprises: a foot-support means adapted to receive and support the foot of the user thereof; means adapted to releasably secure said foot of the user to said foot-support means; and a second reciprocal carriage means forming part of said frame structure, said foot-support means being mounted to said carriage means.
Claim 7
Dependent Claim
105 words
An apparatus as recited in claim 5, wherein said reciprocal carriage means for said right and left arm-control actuators comprises: at least one bearing rod horizontally disposed and secured to said frame structure; and a bearing block slidably mounted on said bearing rod, wherein said bearing block is connected to said respective first or second hydraulic cylinder motor, and wherein said respective handle-bar members are attached to said respective bearing blocks of each right and left arm-control actuator, whereby the active arm or arms of the user can establish a means to activate said hydraulic system in accordance with the selective arrangement of said valves.
Claim 8
Dependent Claim
106 words
An apparatus as recited in claim 6, wherein each of said reciprocal carriage means of said right and left leg-control actuators comprises: at least one bearing rod horizontally disposed and secured to said frame structure; and a bearing block slidably mounted on said bearing rod, wherein said bearing block is connected to said respective third and fourth hydraulic cylinder motors, and wherein said respective foot-support means is mounted to said bearing blocks of said right and left leg-control actuators, whereby the active leg or legs of said user can establish a means to activate said hydraulic system in accordance with the selective arrangement of said valves.
Claim 9
Dependent Claim
39 words
An apparatus as recited in claim 7, wherein said chair-support means includes: an adjustable chair mounted to said frame structure; means to adjust said chair in a vertical position; and means to rotate said chair about a vertical axis.
