Abstract
Abstract A clamp assembly for securing a band about a flexible pipe includes a plurality of substantially U-shaped members clamping the ends of the band together as they are wrapped about pin members having axial undercuts therein. The pins are so disposed that their undercuts face away from one another, and legs of the clamps have ends complementary in shape with the undercuts so as to force portions of the band lying between the pins and the clamp member into intimate contacting engagement with the undercuts.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A clamp assembly for securing a band about a flexible pipe, the band being flexible and having outwardly curled ends, and elongated pins engageable with said curled ends, comprising, said pins having co-axial undercut portions located in the outer surfaces thereof, said pins lying within said curled ends and being so disposed that said undercut portions thereof face away from one another, portions of said curled ends overlying said undercut portions, and at least one resilient clamp member having portions thereof extending toward one another and being complementary in shape to said undercut portions, said clamp member extending transversely of said pins, said complementary portions of said clamp member engaging said overlying portions of said ends for forcing said overlying portions into intimate contacting engagement with said undercut portions, whereby said band is securely held about the flexible pipe while said clamp member is locked in place with said complementary portions and said overlying portions being seated within said undercut portions.
Claim 2
Dependent Claim
161 words
A clamp assembly for securing a band about a flexible pipe, the band being flexible and having outwardly curled ends, and elongated pins engageable with said curled ends, comprising, said pins having co-axial undercut portions located in the outer surfaces thereof, said pins lying within said curled ends and being so disposed that said undercut portions thereof face away from one another, portions of said curled ends overlying said undercut portions, and at least one resilient clamp member having portions thereof extending toward one another and being complementary in shape to said undercut portions, said clamp member extending transversely of said pins, said complementary portions of said clamp member engaging said overlying portions of said ends for forcing said overlying portions into intimate contacting engagement with said undercut portions, whereby said band is securely held about the flexible pipe while said clamp member is locked in place with said complementary portions and said overlying portions being seated within said undercut portions.
Claim 3
Dependent Claim
71 words
The assembly according to claim 1, wherein said undercut portions extend along the entire length of said pins, and a plurality of clamp members are spaced along said pins and extend transversely thereof, each said clamp member having portions thereof extending toward one another and being complementary in shape to said undercut portions, said complementary portions engaging said overlying portions for forcing them into intimate contacting engagement with said undercut portions.
Claim 4
Dependent Claim
46 words
The assembly according to claim 1, wherein said clamp member is substantially U-shaped and has a base portion bridging said pins, said clamp member further having leg portions extending outwardly of said base portion, said leg portions having inner and end edges defining said complementary portions.
Claim 5
Dependent Claim
79 words
The assembly according to claim 3, wherein each said undercut portion is defined by a plane surface intersecting an outer surface of each said pin, and is further defined by a surface of variable radius merging with the remainder of said outer surface, said remainder surface having a fixed radius, and said inner and end edges of said leg portions respectively lying parallel to said surface of variable radius and to said plane surface of each said pin member.
Claim 6
Dependent Claim
14 words
The assembly according to claim 1, wherein a resilient closed cover underlies said band.
