Some theoritical and practice problems of compact shelving

Abstract

In course of the increase of book printing the quantity of the books have burst the monastic and later the chamber libraries too. The libraries with book-stores, that have come into life in the last century are at a total loss. The storage of the books according to their size, also the so called mechanical storage can only make use of the room vertically. To make use of the room vertically and horizontally as well various compact shelving systems have developed, this means making use of the passages too, that took up about 2/3rd of the room. The author of the article examines the different compact shelving systems according to certain viewpoints (the source of power to move the shelves, the direction of moving, significanses of the tracks etc.). The whole article is arranged according to the direction of moving the shelves. This moving can be the following:
1. in the axis of the shelf, in this case
a/ the whole shelf moves from its resting point (Foulkes Mobile Storage System "Stormor", Rolstor, NSE, Gawrecki etc.)
b/ the frame of the shelf stops in its place and only certain parts of the shelf move (W. R. Ames Co "Stormor Drawers", Hamilton Campo Stacks.)
2. The shelf moves in the direction of the shelve's front and paralelly (Compactus System Ingold, The man moved Soviet Types and the first application of these here in Hungary)
3. Those that move the shelf forming a right angle to the axis resp. to the front and of the shelf or turn them out to the angle of 180°. (Sneed roller cases. Art Metal, Deforg etc.)
The article gives an evaluating review of the certain systems, and also examines the question of choosing the most appropriate compact shelving systems.
