Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
248 words
A limb protective covering comprising an elongate generally tubular, flexible, waterproof plastic member having at one end of one of an integral foot and hand receiving member and at the other end an opening receiving the limb to be covered, an elongate strap-like closure member adapted to encircle the limb of a user below said opening, said closure member having a heat sealed substantially single line portion transverse to the length of the closure member fixed to the wall of said tubular member adjacent the said opening as the sole engagement of the closure member to the tubular member, said closure member having first and second strap members extending from opposite sides of said heat sealed transverse line portion, said first member having a rigid loop on one end remote from the panel, the second strap member passing through said rigid loop, a stop member on the end of said second strap, mating engagement fabric portions on said strap and on said stop member whereby said second strap may be drawn through said rigid loop of the first member, tightened into a water-tight seal on the limb and engaged upon itself with the mating engagement fabric of said second strap and stop member, a stabilizing loop heat sealed by a line portion at each end on said plastic tubular member and overlying said closure member at said transverse heat sealed line portion of the tubular member whereby to support said closure member and stabilize the same against removal.
Claim 2
Dependent Claim
248 words
A limb protective covering comprising an elongate generally tubular, flexible, waterproof plastic member having at one end of one of an integral foot and hand receiving member and at the other end an opening receiving the limb to be covered, an elongate strap-like closure member adapted to encircle the limb of a user below said opening, said closure member having a heat sealed substantially single line portion transverse to the length of the closure member fixed to the wall of said tubular member adjacent the said opening as the sole engagement of the closure member to the tubular member, said closure member having first and second strap members extending from opposite sides of said heat sealed transverse line portion, said first member having a rigid loop on one end remote from the panel, the second strap member passing through said rigid loop, a stop member on the end of said second strap, mating engagement fabric portions on said strap and on said stop member whereby said second strap may be drawn through said rigid loop of the first member, tightened into a water-tight seal on the limb and engaged upon itself with the mating engagement fabric of said second strap and stop member, a stabilizing loop heat sealed by a line portion at each end on said plastic tubular member and overlying said closure member at said transverse heat sealed line portion of the tubular member whereby to support said closure member and stabilize the same against removal.
