Legs exercising physical therapy device

Claim 1

Legs exercising physical therapy device utilizeable alternatively with chair and sleeping bed patient carriers, said legs exercising physical therapy device comprising: (A) a substantially horizontal transverse-bar intersecting a longitudinally extending horizontal central-axis; (B) upright standard means including: a tubular-collar extending vertically and non-pivotable uprightly from a central portion of said transverse-bar whereby said tubular-collar overlies said central-axis, a vertical riser slidably associated within said tubular-collar and being provided with a transversely extending bearing located above said tubular-collar, and standard-setscrew means extending from the tubular-collar and against the slidably associated riser for locking the riser at various elevations; (C) cranking means comprising a pair of crank-offset portions respectively flanking the vertical riser and further comprising an intervening crank-shaft portion journalled by said transversely extending bearing of the vertical riser, said respective crank-offset portions being provided with rotatably secured pedals for engagement by the patient's feet; and (D) a pair of elongate wings flanking said tubular-collar, the two wings having their sole connection at said transverse-bar and respectively comprising three substantially horizontal and colinearly extending arms including: (i) a pair of substantially horizontal and tubularly polygonal primary-arms respectively having a front-end and a rear-end, said primary-arms flanking said tubular-collar and being located beneath the transverse-bar, each said primary-arm adjacent the front-end thereof being pivotably attached to the transverse-bar with a releasable locking means for maintaining the angular relationship between the primary-arm and the transverse-bar; (ii) a pair of substantially horizontal secondary-arms of U-shaped channel cross-section and respectively having a lead-end and a trail-end, each said secondary-arm being telescopically received within a primary-arm at the rear-end thereof, and primary-setscrew means extending between the primary-arm and the secondary-arm and the secondary-arm for releasably maintaining a selected telescoped lengthwise relationship between the primary-arm and secondary-arm, wherein the secondary-arm, nearer to the trail-end than to the lead-end, is provided with a vertical aperture therethrough; and (iii) a pair of substantially horizontal and wholly uniplanar tertiary-arms and respectively having a head-end relegated within the channel of the secondary-arm, each said tertiary-arm adjacent the head-end thereof being removably connected at said aperture to the secondary-arm adjacent the trail-end thereof.
