Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
76 words
A self-recoiling elastomeric hose comprising a plurality of integral convolutions, each of said convolutions with said hose in a coiled unextended condition being arranged roughly in a plane which is approximately parallel to associated planes of adjacent convolutions and each convolution having roughly a figure eight configuration defined by a pair of coils which have the appearance of being tangent when viewed normal to their associated plane said hose having a tendency to maintain said configuration.
Claim 2
Dependent Claim
76 words
A self-recoiling elastomeric hose comprising a plurality of integral convolutions, each of said convolutions with said hose in a coiled unextended condition being arranged roughly in a plane which is approximately parallel to associated planes of adjacent convolutions and each convolution having roughly a figure eight configuration defined by a pair of coils which have the appearance of being tangent when viewed normal to their associated plane said hose having a tendency to maintain said configuration.
Claim 3
Dependent Claim
13 words
A hose as set forth in claim 1 made of a thermoplastic material.
Claim 4
Dependent Claim
15 words
A hose as set forth in claim 2 in which said thermoplastic material is nylon.
Claim 5
Dependent Claim
29 words
A hose as set forth in claim 1 in which said figure eight configuration of each convolution is defined by a pair of cooperating coils which are substantially circular.
Claim 6
Dependent Claim
48 words
A hose as set forth in claim 4 and further comprising another coil adjoining at least one of said pair of cooperating coils, said other coil being approximately equal in size to its associated coil and being arranged substantially flatly thereagainst with said hose in a coiled condition.
Claim 7
Dependent Claim
48 words
A hose as set forth in claim 4 and further comprising another coil adjoining each of said pair of cooperating coils, each of said other coils being approximately equal in size to its associated coil and being arranged substantially flatly thereagainst with said hose in a coiled condition.
Claim 8
Dependent Claim
35 words
A hose as set forth in claim 4 and further comprising a pair of fittings at opposed ends thereof with one of said fittings being adapted to attach said hose to a source of fluid.
Claim 9
Dependent Claim
27 words
A hose as set forth in claim 4 made of a thermoplastic material having an elastic memory and being particularly adapted to convey a fluid under pressure.
Claim 10
Dependent Claim
19 words
A hose as set forth in clAim 8 wherein said thermoplastic material is nylon and said fluid is air.
