Abstract
Abstract The invention concerns a system for the unsupervised control of the use of lockers or the like in bath houses, reading rooms, hotels or the like in which the locker doors are provided with a deposit lock; in order to optimize the possibilities of variation while retaining the most favorable structural shape, the locks are operated with codes such that the deposit locks can be brought into the position of readiness to receive a code and store the code and the memory is automatically erased upon the return of the deposit coin.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
A system for the unsupervised control of the use of lockers and the like having locker doors, comprising a deposit lock on each of the locker doors of the lockers adapted for depositing a deposit coin, the deposit lock having memory means for receiving and storing therein any code of a plurality of codes, the deposit lock including locking means and the memory means being connected to the locking means, the deposit lock being lockable and unlockable upon said memory means receiving said code and upon presenting the same code to the deposit lock, respectively, means for automatically erasing the stored code from said memory means upon return of the deposit coin, control elements each containing a respective code, the deposit lock includes means for reading the code from the control elements, said memory means of said deposit lock enters therein said code, read by the reading means, of any of said control elements, each of said control elements is cooperatable with said deposit lock so as to enable locking every deposit lock of unused lockers of the system, and means on the respective deposit lock for providing the control element cooperating therewith with visible identification of the respective deposit lock.
Claim 2
Independent Claim
201 words
A system for the unsupervised control of the use of lockers and the like having locker doors, comprising a deposit lock on each of the locker doors of the lockers adapted for depositing a deposit coin, the deposit lock having memory means for receiving and storing therein any code of a plurality of codes, the deposit lock including locking means and the memory means being connected to the locking means, the deposit lock being lockable and unlockable upon said memory means receiving said code and upon presenting the same code to the deposit lock, respectively, means for automatically erasing the stored code from said memory means upon return of the deposit coin, control elements each containing a respective code, the deposit lock includes means for reading the code from the control elements, said memory means of said deposit lock enters therein said code, read by the reading means, of any of said control elements, each of said control elements is cooperatable with said deposit lock so as to enable locking every deposit lock of unused lockers of the system, and means on the respective deposit lock for providing the control element cooperating therewith with visible identification of the respective deposit lock.
Claim 3
Dependent Claim
61 words
The system according to claim 1, further comprising master key means for opening said deposit lock regardless of the code stored in said memory means of the deposit lock without erasing said memory means of the deposit lock after such opening by the master key means, even upon removal of the deposit coin, until a next opening of the deposit lock.
Claim 4
Independent Claim
206 words
A system for the unsupervised control of the use of lockers and the like having locker doors, comprising a deposit lock on each of the locker doors of the lockers adapted for depositing a deposit coin, the deposit lock having memory means for receiving and storing therein any code of a plurality of codes, the deposit lock including locking means and the memory means being connected to the locking means, the deposit lock being lockable and unlockable upon said memory means receiving said code and upon presenting the same code to the deposit lock, respectively, means for automatically erasing the stored code from said memory means upon return of the deposit coin, master key means for opening said deposit lock regardless of the code stored in said memory means of the deposit lock without erasing said memory means of the deposit lock after such opening by the master key means, even upon removal of the deposit coin, until a next opening of the deposit lock, and said master key means further is for transmitting an erase command with time delay to the memory means for erasing the memory means upon such opening by the master key means when the locker door remains in an open position.
Claim 5
Independent Claim
206 words
A system for the unsupervised control of the use of lockers and the like having locker doors, comprising a deposit lock on each of the locker doors of the lockers adapted for depositing a deposit coin, the deposit lock having memory means for receiving and storing therein any code of a plurality of codes, the deposit lock including locking means and the memory means being connected to the locking means, the deposit lock being lockable and unlockable upon said memory means receiving said code and upon presenting the same code to the deposit lock, respectively, means for automatically erasing the stored code from said memory means upon return of the deposit coin, master key means for opening said deposit lock regardless of the code stored in said memory means of the deposit lock without erasing said memory means of the deposit lock after such opening by the master key means, even upon removal of the deposit coin, until a next opening of the deposit lock, and said master key means further is for transmitting an erase command with time delay to the memory means for erasing the memory means upon such opening by the master key means when the locker door remains in an open position.
Claim 6
Dependent Claim
76 words
The system according to claim 3, further comprising control elements each containing a respective code, the deposit lock includes means for reading the code from the control elements, said memory means of said deposit lock enters therein said code, read by the reading means, of any of said control elements, and each of said control elements is cooperatable with said deposit lock so as to enable locking every deposit lock of unused lockers of the system.
Claim 7
Dependent Claim
21 words
The system according to claim 3, further comprising a keyboard which is activated by the deposit coin for providing said code.
Claim 8
Dependent Claim

The system according to claim 3, wherein said memory means includes a main memory and a buffer memory, and wherein said buffer memory receives the code and retains the code for a short period of time and the code therein is only transferred to said main memory if the deposit lock is closed within a predetermined period of time after insertion of the deposit coin.
Claim 9
Dependent Claim
42 words
The system according to claim 6, wherein said lock has a bolt operatively connected to said memory means such that the transfer of the code from the buffer memory into said main memory takes place upon a forward movement of said bolt.
Claim 10
Dependent Claim
27 words
The system according to claim 6, wherein said lock has an actuating handle and the receiving of the code in the buffer memory activates said actuating handle.
