Abstract
Abstract A bookrack comprising an open framework of metal wire elements includes spaced, parallel rails constituting an inclined floor for supporting a series of books in a position inclined from the vertical, so that their titles may be viewed easily from levels above the horizontal surface of a table top, desk, or other support on which the rack may be seated. Bookends connected by retracting springs are detachably mounted on the floor rails for slidable movement thereon longitudinally of the rack. An element constituting one longitudinal side bar of the rack frame is arranged to provide a stop engageable by books positioned between the bookends to hold the books in positions in which no part of any of the books is in contact with the horizontal surface of a support on which the rack may be seated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
A bookrack comprising an oblong frame of metal wire stock including a straight, longitudinal side bar, an end section at each end thereof and extending transversely of the frame, a pair of rails disposed in laterally spaced relation in the frame parallel to each other and to the side bar, a fixed connection between each end of each rail and its adjacent end section, a riser between each end of the side bar and one end of its adjacent end section, the other end of each end section depending therefrom as a foot portion, the body of each end section extending from the top of its foot portion to the bottom of its associated riser, at least one bookend including a body portion, leg portions, and a rail engaging hook portion on each leg comprised of a single length of inherently resilient metal wire stock, said rail engaging portions disposed at the bottom ends of said legs in the form of terminal hooks slidably engageable with said rails and disposed substantially perpendicular thereto, whereby when said body is raised toward a vertical position, said hooks bind on said rails to resist sliding movement thereon.
Claim 2
Dependent Claim
194 words
A bookrack comprising an oblong frame of metal wire stock including a straight, longitudinal side bar, an end section at each end thereof and extending transversely of the frame, a pair of rails disposed in laterally spaced relation in the frame parallel to each other and to the side bar, a fixed connection between each end of each rail and its adjacent end section, a riser between each end of the side bar and one end of its adjacent end section, the other end of each end section depending therefrom as a foot portion, the body of each end section extending from the top of its foot portion to the bottom of its associated riser, at least one bookend including a body portion, leg portions, and a rail engaging hook portion on each leg comprised of a single length of inherently resilient metal wire stock, said rail engaging portions disposed at the bottom ends of said legs in the form of terminal hooks slidably engageable with said rails and disposed substantially perpendicular thereto, whereby when said body is raised toward a vertical position, said hooks bind on said rails to resist sliding movement thereon.
