Abstract
Abstract An ankle support including a pliable single-piece jacket fittable about a person's foot and ankle. Joined to opposite sides of the jacket are elongated stiffening strips which define generally inverted-T-shaped stiffened regions in such sides. The support may be used on either a left or a right foot. A single seam which joins a pair of edges in the jacket is positioned, for wearing comfort reasons, to lie beneath a person's foot with the jacket fitted in place.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
An ankle support in operative condition comprising a pliable jacket removably fitted about a person's foot and ankle, including a pair of side expanses which extend over opposite sides of the ankle, a first elongated stiffening strip joined to the outside of and stiffening one elongated region in that expanse which extends over the lateral side of the ankle, said first stiffening strip extending over the Lateral Malleolus in the ankle, along a course substantially paralleling natural ligaments in the ankle, and a second elongated stiffening strip joined to the outside of and stiffening another elongated region of the same expanse, said second stiffening strip having one end overlapping said first stiffening strip at a point therealong which is adjacent the Lateral Malleolus, and extending upwardly away from its said one end along a course substantially paralleling other natural ligaments in the ankle, said first and second stiffening strips being arranged in a generally T-shaped configuration on said expanse of said jacket.
Claim 2
Dependent Claim

An ankle support in operative condition comprising a pliable jacket removably fitted about a person's foot and ankle, including a pair of side expanses which extend over opposite sides of the ankle, a first elongated stiffening strip joined to the outside of and stiffening one elongated region in that expanse which extends over the lateral side of the ankle, said first stiffening strip extending over the Lateral Malleolus in the ankle, along a course substantially paralleling natural ligaments in the ankle, and a second elongated stiffening strip joined to the outside of and stiffening another elongated region of the same expanse, said second stiffening strip having one end overlapping said first stiffening strip at a point therealong which is adjacent the Lateral Malleolus, and extending upwardly away from its said one end along a course substantially paralleling other natural ligaments in the ankle, said first and second stiffening strips being arranged in a generally T-shaped configuration on said expanse of said jacket.
Claim 3
Dependent Claim
113 words
An ankle support comprising a pliable jacket securably fittable about a person's foot and ankle, elongated stiffening means joined to the outside of said jacket along substantially its entire length on at least one side thereof forming a plurality of elongated stiffened regions in said one side, which regions extend along different courses that are at an angle to one another and intersect, with the stiffening means overlapping at the point of intersection of said courses, said regions being adapted, with said jacket fitted in place on an ankle, generally to parallel natural ligaments in the ankle, with said point of intersection of said courses extending over the Lateral Malleolus in the ankle.
Claim 4
Dependent Claim
113 words
An ankle support comprising a pliable jacket securably fittable about a person's foot and ankle, elongated stiffening means joined to the outside of said jacket along substantially its entire length on at least one side thereof forming a plurality of elongated stiffened regions in said one side, which regions extend along different courses that are at an angle to one another and intersect, with the stiffening means overlapping at the point of intersection of said courses, said regions being adapted, with said jacket fitted in place on an ankle, generally to parallel natural ligaments in the ankle, with said point of intersection of said courses extending over the Lateral Malleolus in the ankle.
Claim 5
Dependent Claim
27 words
The support of claim 2, wherein said stiffening means, for each stiffened region, comprises at least one elongated stiffening strip attached to said jacket at said region.
Claim 6
Dependent Claim
26 words
The support of claim 2, wherein said stiffening means, for each stiffened region, comprises plural elongated, stacked stiffening strips attached to said jacket at said region.
Claim 7
Dependent Claim
42 words
The support of claim 2, wherein said stiffening means, for each stiffened region, comprises plural, elongated, stacked stiffening strips attached to said jacket at said region, with all of said strips overlapping one another adjacent the point of intersection of said courses.
Claim 8
Dependent Claim
21 words
The support of claim 2, wherein said stiffened regions form a generally T-shaped configuration on said one side of said jacket.
Claim 9
Dependent Claim
105 words
An ankle support comprising a pliable jacket securably fittable about a person's foot and ankle, and two pairs of elongated stiffening strips joined to the outside of said jacket and disposed with one pair on one side of the jacket and the other pair on the opposite side of the jacket, the two strips in a pair of intersecting and overlapping one another to form a generally T-shaped stiffened region in the associated side of the jacket, with the region of overlapping of said strips being adapted, with said jacket fitted in place on an ankle, to extend over the Lateral Malleolus in the ankle.
Claim 10
Dependent Claim
105 words
An ankle support comprising a pliable jacket securably fittable about a person's foot and ankle, and two pairs of elongated stiffening strips joined to the outside of said jacket and disposed with one pair on one side of the jacket and the other pair on the opposite side of the jacket, the two strips in a pair of intersecting and overlapping one another to form a generally T-shaped stiffened region in the associated side of the jacket, with the region of overlapping of said strips being adapted, with said jacket fitted in place on an ankle, to extend over the Lateral Malleolus in the ankle.
Claim 11
Dependent Claim
45 words
The support of claim 7, wherein said jacket is formed of a single web of material including but a single seam between edges in said web, said seam being positioned to lie below the bottom of a person's foot with the jacket fitted in place.
