Abstract
Abstract The present invention relates to a tether device for restricting the range of movement of a child relative to an older person. The tether device comprises a unitary stretch member having a pair of longitudinally extending sides, a pair of transversely extending sides, and a pair of end portions proximate each of said transversely extending sides. The unitary stretch member is stretchable between a relaxed state and taut state, such that the length of said unitary stretch member in the taut state is greater than the length of the unitary stretch member in the relaxed state. A first transversely extending side of said unitary stretch meber is secured to a first end portion of said stretch member to form a first loop a second transversely extending side of said unitary stretch member is secured to a second end portion of said stretch member to form a second loop. The first and second loops constitute first and second elastic wrist bands, respectively. An eleastic tether portion is provided between the first and second eleastic wrist bands. Preferred embodiments of the foregoing device are also disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
195 words
A safety tether device, comprising: a unitary stretch member having an inner elastic member and an outer inelastic cloth tube surrounding said inner elastic member and sewn thereto, said inner elastic member having a first length in a relaxed state and stretching to a second length in a taut state greater than the first length in the relaxed state, said inelastic cloth tube being gathered into folds about said elastic member in the relaxed state of the elastic member and unfolded to the second length of the elastic member in the taut state; said unitary stretch member having a pair of longitudinally extending sides, a pair of transversely extending sides and a pair of end portions, a first transversely extending side being sewn to a first end portion to form a first closed wrist loop and a second transversely extending side being sewn to a second end portion to form a second closed wrist loop, said first loop being larger than said second loop in the relaxed state; and a tether portion defined between said first and second loops, said tether portion and said first and second loops including only machine washable and dryable materials.
Claim 2
Dependent Claim
195 words
A safety tether device, comprising: a unitary stretch member having an inner elastic member and an outer inelastic cloth tube surrounding said inner elastic member and sewn thereto, said inner elastic member having a first length in a relaxed state and stretching to a second length in a taut state greater than the first length in the relaxed state, said inelastic cloth tube being gathered into folds about said elastic member in the relaxed state of the elastic member and unfolded to the second length of the elastic member in the taut state; said unitary stretch member having a pair of longitudinally extending sides, a pair of transversely extending sides and a pair of end portions, a first transversely extending side being sewn to a first end portion to form a first closed wrist loop and a second transversely extending side being sewn to a second end portion to form a second closed wrist loop, said first loop being larger than said second loop in the relaxed state; and a tether portion defined between said first and second loops, said tether portion and said first and second loops including only machine washable and dryable materials.
Claim 3
Dependent Claim
14 words
A safety tether device according to claim 1 wherein said cloth tube comprises cotton.
Claim 4
Dependent Claim
16 words
A safety tether device according to claim 1 wherein said cloth tube comprises a cotton-polyester blend.
Claim 5
Dependent Claim
25 words
A safety tether device according to claim 1 wherein said elastic member comprises a flexible stretchable fabric made with interwoven strands of an elastic material.
Claim 6
Dependent Claim
27 words
A safety tether device according to claim 1 wherein said first loop and said second loop are incapable of fitting over the head of a small child.
Claim 7
Dependent Claim
23 words
The tether device of claim 1 wherein a stretch ratio of the second length to the first length is between 1.25 and 1.90.
Claim 8
Dependent Claim
13 words
The tether device of claim 6 wherein the stretch ratio is about 1.5.
Claim 9
Dependent Claim
38 words
The tether device of claim 1 wherein a ratio of the length of the stretch member to the width of the stretch member is 10 to 1 in both the relaxed and taut states of the elastic member.
Claim 10
Dependent Claim
38 words
The tether device of claim 1 wherein a ratio of the width of the stretch member to the thickness of the stretch member is 3 to 1 in both the relaxed and taut states of the elastic member.
