  • Patent number: 5415372
    Abstract: A book cover assembly has a book, a cover and a retainer securing the book to the cover.

The biasing means engage the pivot members under urging from the book as it falls from an open upper position.The mounting assembly is disposed at 45.degree. to the spine of the book cover assembly and is hinged at 45.degree. to a mounting plate so that the book can be moved from a preferred stored orientation which is side face-out to a conventional open orientation with the spine at 90.degree. to its original position. A variation for accommodating a pair of books in tandem is also described in which the books will locate in a preferred orientation.
