Abstract

Claim 1
Independent Claim
102 words
A rotating hinge mechanism comprising a pair of hollow cylinders arranged to rotate within one another and restricted in axial movement thereby, means for attaching an external spoke-like member to the periphery of the outer cylinder, an outer member extending over said spoke-like member, said outer member being attached by means accessible only through openings in both said cylinders, and means for attaching another outer member into the inner cylinders, said other member extending axially therefrom, the latter said attaching means being accessible only through an opening in the periphery of the outer cylinder at a predetermined rotational relationship between said cylinders.
