Abstract

A system for controlling access to several keys that includes several keyholders that include uniquely shaped portions that mate with correspondingly shaped portions of keyholder housings that are contained within a storage container. The storage container keyholder housings further include a latching apparatus for latching each of the keyholders such that the key and keyholders may not be removed unless an access signal is received by the latching apparatus. A data processor is connected to the storage means to receive inputs and provide access to selected keys in response to appropriate inputs. The data processor further records information such as time of access and access data. The storage keyholder housings further include circuitry that determine when a key has been replaced. The data processor is connected to receive the return information for recording. The data processor is further configured to provide output reports listing information as to access, return and usage. In another embodiment, a system is provided for controlling access to several keys that includes keyholders having unique identification codes that are read by circuitry within a storage container or by the data processor. The system data processor controls access to the keys and records return of the keys via the keyholder identification code.

Claims

1. A system controlling access to a plurality of keys or the like comprising:

a plurality of individual keyholders, each attached to at least one of the keys and including an individually coded mating means for enabling insertion of the holder and key in only a keyholder housing having a corresponding individually coded mating means;

a storage means containing a plurality of the keyholder housings and for controlled storage of the keys and keyholders and including access means for providing access to selected ones of the keys and keyholders in response to an access signal while preventing access to the selected ones of the keys and keyholders in the absence of said access signal and further including means for indicating the return of a key and keyholder to its appropriate keyholder housing;

input means for receiving input data from a system user requesting access to at least one selected key;

display means for providing information to the system user; and

processing means connected to the storage means, the input means and the display means for receiving the input data, for providing information to the display means, for determining access from the input date in accordance with stored data, for generating the access signal upon determining a grant of access, for recording the access grant, for receiving the return signal and for recording the return.

2. A system according to claim 1 wherein said mating means and the corresponding mating means includes pins and matching pin sockets.

3. A system according to claim 1 wherein the mating means and the corresponding mating means includes formations on the keyholder and corresponding mating formations are within the keyholder housing.

4. A system according to claim 1 wherein said access means includes a spring loaded latch that is addressably activated by the access signal.

5. A system according to claim 4 wherein said storage means includes a switch which provides the return signal when the keyholder and key are inserted into the matching keyholder housing.

6. A system according to claim 1 wherein said processing means further includes an alarm which is activated when removal of any keyholders and keys are attempted without a grant of access.

7. An apparatus for controlling access to a plurality of similarly shaped objects comprising:

a plurality of individual object holder means, each for physical attachment to at least one of the objects and including an individually coded mating means for enabling storage of the holder means and object only in a holder housing having a corresponding individually coded mating means; and

a storage means containing a plurality of the holder housings and for controlling storage of the holder means and objects and including means for providing access to selected ones of the holder means and attached objects in response to an authorization signal while preventing access to the selected ones of the holder means and attached objects in the absence of said authorization signal.

8. An apparatus according to claim 7 wherein said mating means and the corresponding mating means includes pins and matingly matching pin sockets.

9. An apparatus according to claim 8 wherein the mating means and the corresponding mating means includes formations upon the holder and correspondingly mating formations upon the holder housing.

10. An apparatus according to claim 9 wherein said formations include tongues formed upon the holder surface and corresponding grooves formed within the holder housing surface providing for mating of the tongues and grooves when the appropriate holder is inserted in the holder housing.

11. A system for controlling access to a plurality of similarly shaped objects comprising:

a storage means for storing a plurality of said objects, for providing access to selected one of said objects in response to an access signal while preventing access to the selected ones of said objects in the absence of said access signal, and for providing a return signal when an accessed object is returned to the storage means; and

data processing means connected to said storage means and including an input means for receiving input data from a system user, said data processing means being operative for determining access to selected one of the objects in response to the input data and stored data and when access is determined providing said access signal. for receiving said return signal and for recording grant of access and occurrence of return of accessed objects.

12. A system according to claim 11 wherein said storage means includes access means having a spring loaded latch that is addressably activated by the access signal.

13. A system according to claim 12 wherein said storage means further includes a switch which provides the return signal when the accessed object is returned.

14. A system according to claim 13 wherein said data processing means further includes an alarm circuit to provide an alarm when removal of any objects are attempted without access being granted.

15. An apparatus for managing distribution of a plurality of similarly shaped objects comprising:

a plurality of individual object holder means, each for attachment to at least one of the objects and for providing an individually coded identification; and

a plurality of holder housing means, each for controlling the storage of a holder means and attached objects and including identification reading means for determining the holder means identity and including means for providing access to the holder means when selected while preventing access to the holder means when not selected.

16. An apparatus according to claim 15 further including a storage cabinet to contain the plurality of holder housing means and including address means for addressing each holder housing for determining the holder identification and for providing access.

17. An apparatus according to claim 15 wherein said holder means includes a magnetic encoded means for providing the holder identification.

18. An apparatus according to claim 15 wherein said holder means includes an optically encoded means for providing the holder identification.

19. An apparatus according to claim 15 wherein said holder means includes an electronic circuit means for providing the holder identification.

20. A system for controlling access to a plurality of keys or the like comprising:

a plurality of individual keyholders, each attached to at least one of the keys and included means for providing a unique keyholder identification;

a plurality of keyholder housings including means for controlled storage of the keys and keyholders and including means for determining the keyholder identification when the keyholder is inserted therein, including access means for providing access to the keyholder in response to an access signal while preventing access to the keyholder in the absence of said access signal;
