Abstract
Abstract A pair of boots each having an outer shell and an inner resilient liner are each contoured to fit at the juncture between a person's foot and leg. The shell and liner of each contoured boot have extended ends that are folded over each other, and secured in the folded position to the person's leg. A support member, attached to the front of the shell, in turn provides for inverted suspension of the person from an independent support member, and a loop attached to the front of the shell extends to contact the back of the person's leg to give torque free suspension to a person wearing the boots.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
An inversion boot adapted for attachment to a person's leg for suspending that person in an inverted position wherein said boot comprises: a resiliently lined support member; means for adjustably clamping said support member to a person at the juncture of a person's leg and foot; support means secured to said support member for transferring the person's weight to an independent supporting surface and for centering the load created by a person's weight when in the inverted position; said support means comprising a hook secured to said support member on the front side of said support member and a loop secured to the support member on the front side of said support member wherein the loop extends from alongside the hook, curvilinearly upward so as to engage the back of a person's leg when a boot is clamped onto the foot.
Claim 2
Dependent Claim
141 words
An inversion boot adapted for attachment to a person's leg for suspending that person in an inverted position wherein said boot comprises: a resiliently lined support member; means for adjustably clamping said support member to a person at the juncture of a person's leg and foot; support means secured to said support member for transferring the person's weight to an independent supporting surface and for centering the load created by a person's weight when in the inverted position; said support means comprising a hook secured to said support member on the front side of said support member and a loop secured to the support member on the front side of said support member wherein the loop extends from alongside the hook, curvilinearly upward so as to engage the back of a person's leg when a boot is clamped onto the foot.
Claim 3
Dependent Claim
147 words
An inversion boot adapted for attachment to a person's leg for suspending that person in an inverted position wherein said boot comprises: a preformed resilient shell having normally and automatically closed overlapping ends that may be opened to permit placement on a person at the juncture of said person's foot and leg then to automatically close with said ends overlapping around the leg, a resilient liner secured to the inside of the shell, a buckle secured to an outer surface of the shell, a strap secured at one end to the outer surface of the shell with the other end of the strap extended to permit encircling the overlapping shell and to be adjustably secured in the buckle, and means secured to the shell for transferring the person's weight to an independent support means for suspending the person in an inverted position from the independent support means.
Claim 4
Dependent Claim
147 words
An inversion boot adapted for attachment to a person's leg for suspending that person in an inverted position wherein said boot comprises: a preformed resilient shell having normally and automatically closed overlapping ends that may be opened to permit placement on a person at the juncture of said person's foot and leg then to automatically close with said ends overlapping around the leg, a resilient liner secured to the inside of the shell, a buckle secured to an outer surface of the shell, a strap secured at one end to the outer surface of the shell with the other end of the strap extended to permit encircling the overlapping shell and to be adjustably secured in the buckle, and means secured to the shell for transferring the person's weight to an independent support means for suspending the person in an inverted position from the independent support means.
Claim 5
Dependent Claim
52 words
An inversion boot adapted for attachment to a person's leg for suspending that person in an inverted position as in claim 2, wherein the means secured to the shell for transferring the person's weight to the independent support means comprises a hook secured to the shell at the front of the leg.
Claim 6
Dependent Claim
59 words
An inversion boot for attachment to a person's leg for suspending that person in an inverted position as in claim 3, with the inversion boot further comprising: a loop secured to the shell adjacent the hook with an end of the loop located to press against the back of the suspended person's leg to provide a load centering means.
Claim 7
Dependent Claim
46 words
An inversion boot adapted for attachment to a person's leg for suspending that person in an inverted position as in claim 4, with the device further comprising: a resilient material covering the loop at the location on the loop that is contacted by the person's leg.
