Abstract
Abstract Therapeutic apparatus to aid certain disabled and bedridden persons to participate in physical activities otherwise prevented because of their infirmities. In one embodiment of the invention, the apparatus includes an exercise bar supported above a bed by a block and tackle assembly connected with motor means operative therethrough to reciprocate the bar vertically. The bar is also supported for angular displacements about a generally vertical axis, and a reversible drive motor may be included to impart angular displacements to the bar. The apparatus may be used, for example, in exercising the back, leg, arm, and shoulder muscles of a bedridden person.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
In apparatus of the character described: oscillator structure adapted to be located over a bed or the like in spaced relation therewith and to be vertically reciprocable with respect thereto; support mechanism for said oscillator structure to support the same at such location including hanger means attachable to a fixed support therefor, and carrier means interconnecting said oscillator structure aNd hanger means in supporting the former; and motor means operatively connected with said carrier means for effecting reciprocable displacements therethrough of said oscillator structure, said oscillator structure comprising a concave basket having an open bottom, said carrier means being connected to said basket at spaced apart locations therealong.
Claim 2
Dependent Claim
108 words
In apparatus of the character described: oscillator structure adapted to be located over a bed or the like in spaced relation therewith and to be vertically reciprocable with respect thereto; support mechanism for said oscillator structure to support the same at such location including hanger means attachable to a fixed support therefor, and carrier means interconnecting said oscillator structure aNd hanger means in supporting the former; and motor means operatively connected with said carrier means for effecting reciprocable displacements therethrough of said oscillator structure, said oscillator structure comprising a concave basket having an open bottom, said carrier means being connected to said basket at spaced apart locations therealong.
Claim 3
Dependent Claim
14 words
The apparatus of claim 1 in which said motor means comprises an electric motor.
Claim 4
Dependent Claim
15 words
The apparatus of claim 6 in which said electric motor is a variable speed motor.
Claim 5
Dependent Claim
105 words
The apparatus of claim 2 in which said motor means further comprises a crank having an arm drivingly connected with said electric motor so as to be rotated thereby and a handle rotatably supported by said arm and orbited thereby along a circular path upon energization of said electric motor, in which said carrier means includes a block and tackle assembly having a cable connected with said handle so as to effect the aforesaid reciprocable displacements of said oscillator structure upon energization of said electric motor, and in which said hanger means includes a pulley wheel forming a part of said block and tackle assembly.
Claim 6
Dependent Claim
48 words
The apparatus of claim 4 in which said handle is adjustably secured to said arm so as to be selectively attached thereto at various locations therealong so that the throw of said crank can be adjusted to vary the extent of the reciprocable displacements of said oscillator structure.
Claim 7
Dependent Claim
31 words
The apparatus of claim 4 in which said carrier means comprises a swivel connection affording angular displacements of said oscillator relative to said hanger means structure about a generally vertical axis.
Claim 8
Dependent Claim
63 words
The apparatus of claim 6 in which said carrier means further comprises a motor drivingly connected with said swivel connection so as to enforce angular displacements therethrough upon said oscillator structure, said basket being equipped with a plurality of paired connectors to which said carrier means are selectively attachable so as to enable the angular orientation of said basket to be selectively adjusted.
