Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
A unitary suspendable one piece snap hook comprising a head portion, a shank portion, the head portion being affixed to one end of said shank portion wherein the maximum thickness of said head member measured perpendicular to the principal axis of said shank portion exceeds the thickness of said shank portion measured perpendicular to the axis of said shank portion, said head portion being anchorable in a suitable external retaining means a body portion unitary with said shank portion comprising a shorter segment and a longer segment extending from the other end of said shank portion in divergent relation to each other, said shorter body segment and said longer body segment lying in substantially a common plane with said shank portion, the end of said longer segment distant from the shank portion being bent upon itself to over-lie the end of said shorter segment at its end distant from the shank to form a loop.
Claim 2
Dependent Claim
155 words
A unitary suspendable one piece snap hook comprising a head portion, a shank portion, the head portion being affixed to one end of said shank portion wherein the maximum thickness of said head member measured perpendicular to the principal axis of said shank portion exceeds the thickness of said shank portion measured perpendicular to the axis of said shank portion, said head portion being anchorable in a suitable external retaining means a body portion unitary with said shank portion comprising a shorter segment and a longer segment extending from the other end of said shank portion in divergent relation to each other, said shorter body segment and said longer body segment lying in substantially a common plane with said shank portion, the end of said longer segment distant from the shank portion being bent upon itself to over-lie the end of said shorter segment at its end distant from the shank to form a loop.
Claim 3
Dependent Claim
41 words
A snap hook in accordance with claim 1 wherein a first concave bend is provided in the shorter body segment proximate to said shank portion, the hollow face of said bend facing inwardly towards the principal axis of the shank portion.
Claim 4
Dependent Claim
51 words
A snap hook in accordance with claim 2 additionally comprising a second concave bend in the longer body segment proximate to said shank portion, the hallow face of said bend facing inwardly towards said principal axis of the shank portion and towards the similar first bend in the longer body segment.
Claim 5
Dependent Claim
36 words
A snap hook in accordance with claim 1 wherein the cross section of the material forming the longer and shorter body segments is substantially semi-circular having the flat portion thereof facing the interior of the hook.
Claim 6
Dependent Claim
43 words
A snap hook in accordance with claim 4 wherein the end of the shorter segment and the end of the longer segment of the body portion at the point where said longer segment end overlies said shorter segment end are both substantially flat.
Claim 7
Dependent Claim
68 words
A snap hook in accordance with claim 4 wherein the end of the shorter segment and the end of the longer segment of the body portion are substantially V-shaped, the arms of the V being of substantially equivalent cross section and the apex of the V pointing outwardly whereby the apex of the V of the longer segment overlies the apex of the V of the shorter segment.
Claim 8
Dependent Claim
214 words
Method of making a unitary suspendable snap hook from a single piece of wire comprising the steps of: i. shearing a segment of wire substantially across a diameter thereof to provide a. a shank portion of full original cross section, b. an arm segment having one end thereof attached to said shank portion and subtending an angle of less than 90* thereto having a substantially semicircular cross section, c. a base segment in substantially linear relation to said shank portion, ii. bending said arm segment and said base segment proximate to said shank portion to provide a concave bend therein the hollow face of said bend facing inwardly to the common shear plane of said segments, iii. bending said arm segment and said base segment to orient said segments in divergent relation in a common plane, iv. cutting one of said segmeNts to provide one segment longer than the other and bending the longer of segments transversely upon itself to overlie the end of said shorter segment to provide a substantially closed loop, and compressing the remaing end of said shank portion to provide a head portion having a maximum diameter relative to the principal axis of the shank portion greater than the diameter of said shank portion relative to its said principal axis.
