Device for the automatic surveillance of swimming-pools, libraries etc., in particular their utilization and their utilization time

摘要

An admission gate (3) comprises an automatic arrangement (6) which is activated by insertion of money and which delivers time-coded closure elements (8), which are in each case adapted to a specific locker (11) or the like provided in the swimming pool, and which are retained upon leaving. In order to substantially prevent misuse, the invention proposes that the automatic arrangement (6) codes the strip- shaped closure elements (8) on delivery identically to a code stored in the associated locker (11).
