Abstract
Abstract A picture album structure having a plurality of pages, a pair of flat, square, picture carriers with rectangular picture viewing windows related to each page, an orienting and holding means to selectively orient and releasably hold the carriers on the pages with the major axes of the carrier windows on central horizontal or vertical axes of the pages. The orienting and holding means comprising elements on the pages with four like portions on right angularly related axes relative to and spaced equal distances radially of the central axes of the pages and elements of similar configuration and arrangement on the carriers, the elements on the pages or on the carriers being magnetic elements and the other of said elements being ferrous whereby the magnetic and ferrous elements align and hold the carriers on the pages when the carriers are arranged adjacent thereto.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
255 words
In combination, a substantially rigid page with a flat surface having a square carrier zone within its perimeter, said zone having horizontal top and bottom edges and vertical side edges, a square picture carrier with a flat front panel with a central rectangular picture window with side edges parallel with adjacent sides of the carriers and a flat rear sheet related to the panel to define an envelope to receive and arrange a picture for viewing through said window, orienting and holding means releasably securing the carrier to the page with the sides of the carrier in adjacent parallel relationship with the edges of the zone, said means including elements on the page and on the carrier, the element on the carrier arranged on the rear sheet with four portions spaced equal distances from an on right angularly related radial axes relative to the center of said carrier, the element on the page arranged within said zone with four portions positioned to register with and occur adjacent the four portions of the element on the carrier when the carrier is positioned adjacent to the page, at least one of the elements being a magnetized element and the other element being a magnetic flux conductive element whereby the elements are releasably held in juxtaposition by magnetic fields, said means serving to selectively releasably hold the carrier and page together with the carrier in one of four rotative positions where tHe major axis of the window is parallel with the horizontal or vertical axes of the page.
