Abstract
Abstract A stretching machine for stretching the legs of an individual which includes a pair of leg bars and a pair of leg decks. Each leg deck is slidingly and pivotingly connected to one of the leg bars to permit adjustments for different leg lengths of individuals. The leg bars are moveable in a general arc from a rest position to stretch positions by a hydraulic jack comprising a jack base, a base jack rod slidingly disposed in the jack base and a connecting rod disposed in the base jack rod. A linkage connects the connecting rod to the leg bars. A channel is slidingly connected to each leg bar and one end of the a pin is connected to the channel, the opposite end of the pin being pivotally disposed in a pivot opening in the leg deck.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
279 words
A stretching machine for stretching the legs of an individual, comprising: a seat adapted for accommodating the individual sitting thereon; a pair of leg bars, each leg bar having a pivot end and an opposite terminating end; means connected to the pivot ends of the leg bars so the leg bars extend a distance from the seat and are disposed generally near each other in a rest position of the leg bars, said means being adapted for moving the terminating ends generally away from each other in a general arc generally about the pivot ends to stretch positions; a pair of leg decks, each leg deck being adapted for supporting a portion of one of the individual's legs; and a pair of slide assemblies, each slide assembly slidingly connecting one of the leg decks to one of the leg bars for sliding movement generally between the pivot end and the terminating end to permit adjustments for different leg lengths of individuals, each slide assembly pivotingly connecting one of the leg decks to one of the leg bars for permitting angular adjustment of the leg decks to accommodate the angles the individual's legs extend from the individual's body in the sitting position, each slide assembly comprising: a channel slidingly connectable to one of the leg bars; and a pivot pin having opposite ends with one end connected to the channel and the pivot pin extending a distance from the channel; and wherein each of the leg decks includes a pivot opening sized and positioned to receive a portion of one of the pivot pins for cooperating to pivotingly connect each of the leg decks to one of the leg bars.
Claim 2
Dependent Claim
279 words
A stretching machine for stretching the legs of an individual, comprising: a seat adapted for accommodating the individual sitting thereon; a pair of leg bars, each leg bar having a pivot end and an opposite terminating end; means connected to the pivot ends of the leg bars so the leg bars extend a distance from the seat and are disposed generally near each other in a rest position of the leg bars, said means being adapted for moving the terminating ends generally away from each other in a general arc generally about the pivot ends to stretch positions; a pair of leg decks, each leg deck being adapted for supporting a portion of one of the individual's legs; and a pair of slide assemblies, each slide assembly slidingly connecting one of the leg decks to one of the leg bars for sliding movement generally between the pivot end and the terminating end to permit adjustments for different leg lengths of individuals, each slide assembly pivotingly connecting one of the leg decks to one of the leg bars for permitting angular adjustment of the leg decks to accommodate the angles the individual's legs extend from the individual's body in the sitting position, each slide assembly comprising: a channel slidingly connectable to one of the leg bars; and a pivot pin having opposite ends with one end connected to the channel and the pivot pin extending a distance from the channel; and wherein each of the leg decks includes a pivot opening sized and positioned to receive a portion of one of the pivot pins for cooperating to pivotingly connect each of the leg decks to one of the leg bars.
Claim 3
Dependent Claim
52 words
The stretching machine of claim 1 wherein each leg deck is defined further to include: a rod having one end connected to the leg deck and the rod extending a distance from the leg deck, the pivot opening for accommodating one of the pivot pins disposed through a portion of the rod.
Claim 4
Dependent Claim
77 words
The stretching machine of claim 1 wherein each leg deck is defined further to include: thigh pad means for engaging a portion of the inside thigh area of an individual; and calf pad means for engaging a portion of the inside calf area of the individual, the thigh pad means being spaced a distance from the calf pad means so the individual's knee area is disposed generally between the thigh pad means and the calf pad means.
Claim 5
Dependent Claim
140 words
The stretching machine of claim 1 wherein the means for moving the leg bars is defined further to include: a hydraulic jack, comprising: a jack base; a base jack rod slidingly disposed in the jack base with an opening intersecting an upper end and extending a distance though the base jack rod terminating with a closed end; the base jack rod being moved out from the jack base when the hydraulic jack is actuated; and a connecting rod disposed in the opening in the base jack rod with one end of the connecting rod engaging the closed end in the base jack rod and the connecting rod extending a distance from the open end of the base jack rod terminating with an upper end; and a linkage for connecting the upper end of the connecting rod to the leg bars.
Claim 6
Dependent Claim
