Claim 5

Dependent Claim 141 words

A book having interlocking handle parts comprising a first cover panel and a second cover panel respectively hingedly connected to opposite longitudinal sides of a spine, a first half of a U-shaped handle on an edge of said first panel and a second half of said U-shaped handle on a corresponding edge of said second panel, said halves being mounted on their respective panel edge by hinge means between the panel edge and ,he ends of the U-arms of each U-shaped handle half to allow said halves to pivot 180° between an extended position with the handle half lying in the plane of each panel and a retracted position in which each half lies substantially flat against the inner face of its panel, and means on each inner face for releasably holding its half of said handle in the retracted position.

Claim 6

Dependent Claim 53 words

A book as claimed in claim 3, wherein, when said book is closed and said halves of said handle are in the extended position, said halves are in face-to-face relationship, are releasable, interlocking means on said halves for holding said halves together to form said handle and also to keep said book closed.

Claim 7

Independent Claim 60 words
