Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A tension band of the type including a support engaging portion with outwardly extending fingers, the improvement comprising an elongated slot formed near the end of one of said fingers, a locking member formed by bending the end of the other finger towards said one finger, a hook having a neck portion and a head portion at the end of said locking member, said head portion extending farther toward one edge of said other finger than the edge of said slot extends toward the corresponding one edge of said one finger, said head portion formed to extend through said slot, a cam surface extending toward said one edge on the outside edge of said head portion, whereby when said hook engages the edge of said elongated slot in said one finger said cam surface moves said other finger laterally relative to said one finger until said head portion passes tHrough said elongated slot and said head portion springs back in a reverse lateral direction to hook the end of said one finger, whereby said fingers are locked together without tension applied thereto.
Claim 2
Dependent Claim
182 words
A tension band of the type including a support engaging portion with outwardly extending fingers, the improvement comprising an elongated slot formed near the end of one of said fingers, a locking member formed by bending the end of the other finger towards said one finger, a hook having a neck portion and a head portion at the end of said locking member, said head portion extending farther toward one edge of said other finger than the edge of said slot extends toward the corresponding one edge of said one finger, said head portion formed to extend through said slot, a cam surface extending toward said one edge on the outside edge of said head portion, whereby when said hook engages the edge of said elongated slot in said one finger said cam surface moves said other finger laterally relative to said one finger until said head portion passes tHrough said elongated slot and said head portion springs back in a reverse lateral direction to hook the end of said one finger, whereby said fingers are locked together without tension applied thereto.
Claim 3
Dependent Claim
81 words
A tension band as in claim 1 wherein said slot includes a narrow portion disposed toward the end of said one finger, said neck portion adapted to fit into the narrow portion of the slot for providing additional locking only when tension forces are applied to move said locking member toward the end of said one finger so that said locking member may be released prior to application of tension forces by moving said other finger in said reverse lateral direction.
Claim 4
Dependent Claim
28 words
A tension band as in claim 2 wherein the end of said one finger is bent towards said other finger thereby providing a stop for said locking member.
Claim 5
