Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A hand warming device for cold environments, comprising: a muff having end openings and being made of a plurality of layers of material, the outer layer thereof being a water repellent material, and an inner layer thereof being an insulating material, an elastic band member disposed in the interior of said muff and adapted to removably hold therein a heat source for warming the hands of the user, closing means at each said end opening for selectively varying the size thereof between fully open and fully closed, and an adjustable belt attached to said muff to secure said muff against a body portion of the user.
Claim 2
Dependent Claim
106 words
A hand warming device for cold environments, comprising: a muff having end openings and being made of a plurality of layers of material, the outer layer thereof being a water repellent material, and an inner layer thereof being an insulating material, an elastic band member disposed in the interior of said muff and adapted to removably hold therein a heat source for warming the hands of the user, closing means at each said end opening for selectively varying the size thereof between fully open and fully closed, and an adjustable belt attached to said muff to secure said muff against a body portion of the user.
Claim 3
Dependent Claim
25 words
The device of claim 1 wherein said inner layer insulating material is of a flexible semi-rigid nature to substantially maintain the shape of said muff.
Claim 4
Dependent Claim
111 words
The device of claim 1 wherein each said closing means at a respective said end opening includes a narrow strip of a first material lining a peripheral portion of said end opening, and a narrow strip of a second material lining the remaining peripheral portion of said end opening, said first material strip having on its outer surface a plurality of minute loop members and said second material having on its outer surface a plurality of minute hook members engageable with said loop members, whereby said end openings may be selectively varied between fully open and fully closed by bringing into engagement selected portions of said first and second material strips.
