Abstract
Abstract A single strip member is provided constructed of non-elastic rigid material having minimal flexive properties and the strip member is constructed in the form of an arcuate band of an angular extent greater than 360° with at least slightly overlapped ends. Each of the ends is in the form of a circumferentially extending channel member with one of the channel members being more narrow than the other channel member and at least partially length wise telescoped therein. The side flanges of one of the channel members have an overcenter swingable actuating lever pivotally supported therefrom for swinging in the plane of the arcuate strip member and an overcenter positionable portion of the lever has one end of a stiff expansion spring anchored relative thereto while the other end of the expansion spring is anchored relative to the other channel member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
203 words
An elongated arcuate strip member having overlapped opposite ends and constructed of non-elastic rigid material having minimal flexive properties, one of said ends including anchor means supported therefrom, the other of said ends including an arcuate lever having one end pivotally supported from said other strip member end for swinging into and out of position closely overlying and paralleling said other end and with said other end of said lever extending in the direction along said strip member in which the latter extends from said other end to said one end of said strip member, an elongated stiff expansion spring having one end anchored relative to said anchor means and the other end anchored relative to said lever intermediate said one and other ends thereof, said one end of said strip member overlapping the outer surface of said other end of said strip member, said opposite ends of said strip member defining channel member portions extending longitudinally of said strip member, said channel member portions opening outwardly of said arcuate strip member, the channel member portion carried by said one end of said strip member being snugly slidably telescoped within the channel member portion defined by said other end of said strip member.
Claim 2
Dependent Claim
203 words
An elongated arcuate strip member having overlapped opposite ends and constructed of non-elastic rigid material having minimal flexive properties, one of said ends including anchor means supported therefrom, the other of said ends including an arcuate lever having one end pivotally supported from said other strip member end for swinging into and out of position closely overlying and paralleling said other end and with said other end of said lever extending in the direction along said strip member in which the latter extends from said other end to said one end of said strip member, an elongated stiff expansion spring having one end anchored relative to said anchor means and the other end anchored relative to said lever intermediate said one and other ends thereof, said one end of said strip member overlapping the outer surface of said other end of said strip member, said opposite ends of said strip member defining channel member portions extending longitudinally of said strip member, said channel member portions opening outwardly of said arcuate strip member, the channel member portion carried by said one end of said strip member being snugly slidably telescoped within the channel member portion defined by said other end of said strip member.
Claim 3
Dependent Claim
20 words
The clamp of claim 1 wherein said expansion spring comprises a coil spring seatingly received in said channel member portions.
Claim 4
Dependent Claim
70 words
The clamp of claim 1 wherein the channel member portion carried by said other end of said strip member includes opposite side flange portions having longitudinally spaced outwardly opening notches formed therein, said one end of said lever including laterally outwardly projecting portions selectively receivable in said notches for pivotally supporting said one end of said lever from said other end of said strip member at points spaced longitudinally therealong.
Claim 5
Dependent Claim
64 words
The clamp of claim 3 wherein said ends of said strip members define channel member portions extending longitudinally of said strip member, said channel member portions opening outwardly of said arcuate strip member, the channel member portion carried by said one end of said strip member being snugly slidably telescoped within the channel member portion defined by said other end of said strip member.
Claim 6
Dependent Claim
20 words
The clamp of claim 4 wherein said expansion spring comprises a coil spring seatingly received in said channel member portions.
Claim 7
Dependent Claim

The clamp of claim 1 wherein said one end of said lever is channel shaped and is received in and opens inwardly toward the channel member portion carried by said other end of said strip member, said channel shaped one end of said lever snugly receiving the adjacent end of said expansion spring therein when said lever is in position generally paralleling said strip member.
Claim 8
Dependent Claim
20 words
The clamp of claim 6 wherein said expansion spring comprises a coil spring seatingly received in said channel member portions.
Claim 9
Dependent Claim
70 words
The clamp of claim 7 wherein the channel member portion carried by said other end of said strip member includes opposite side flange portions having longitudinally spaced outwardly opening notches formed therein, said one end of said lever including laterally outwardly projecting portions selectively receivable in said notches for pivotally supporting said one end of said lever from said other end of said strip member at points spaced longitudinally therealong.
Claim 10
Dependent Claim
56 words
The clamp of claim 1 wherein said anchor means includes an apertured transverse end wall secured across the end of the channel member portion on said one end of said strip member facing along said strip member toward said other strip member end, said expansion spring one end being removably hook-engaged through said apertured end wall.
Claim 11
Dependent Claim
19 words
The clamp of claim 3 wherein said channel member portions are longitudinally arcuate with their convex sides opening outwardly.
