Abstract

A modular drawer structure comprises a housing having an interior volume defined therein, and a drawer comprising one or more compartments, wherein the drawer is slidably movable with respect to the interior volume of the housing between a first closed position, wherein the compartments are enclosed within the interior volume, and a second open position, wherein the compartments are at least partially accessible. The drawer structure further comprises a mechanism for controllably locking the drawer in the first closed position, an access pad, e.g. such as but not limited to a keypad and/or a card swipe pad, for entry of a passcode, and a processor for unlocking the drawer when an entered passcode matches a stored passcode value. Some embodiments of the drawer structure include a stored time threshold, wherein if the drawer is unlocked for a time that meets or exceeds the stored time threshold, the drawer is relocked.

Claims

1. An apparatus comprising:

a base column that extends upward from a first end to a second end and that includes an attachment channel defined therein;

a plurality of spaced attachment points that are located along the attachment channel and configured to receive and secure thereto drawer housings;

a plurality of drawer housings,

where each drawer housing is fixedly attachable to the base column through the attachment channel,

where a drawer opening extends inward from a front end of each drawer housing to define an interior volume, and

where each drawer housing includes a lock and a processor;

a plurality of drawers that each include one or more compartments,

where each drawer is slidably movable with respect to the interior volume of the corresponding drawer housing between

a closed position in which the compartments are inaccessible, and

an open position in which the compartments are at least partially accessible; and

a plurality of access pads mounted to the plurality of drawer housings for entry of a passcode by a user,

wherein each processor is configured to unlock the corresponding lock when the passcode matches a stored passcode value for the corresponding drawer housing.

2. The apparatus of claim 1, wherein the plurality of access pads comprises keypads, card readers, fingerprint scanners, retina scanners, facial recognition systems, or some combination thereof.

3. The apparatus of claim 1, wherein each drawer housing comprises a substantially planar upper surface.

4. The apparatus of claim 3, wherein a ridge extends upward from the substantially planar upper surface around a periphery of each drawer housing, and wherein the ridge is configured to retain any of medications, supplies, writing implements, spills, or small objects.

5. The apparatus of claim 1, wherein each drawer housing comprises a memory that includes the stored passcode value.

6. The apparatus of claim 1, wherein each drawer housing comprises a data port that is connected to the processor.

7. The apparatus of claim 6, wherein each processor is configured to send information through the data port to an external computer.

8. A drawer assembly comprising:

a drawer housing having

a drawer opening that extends inward from a front end of the drawer housing to define an interior volume, and

a notch along a back end of the drawer housing to define an attachment channel,

where the drawer housing includes

one or more fastener components for securing the drawer housing to an attachment point of a base, the one or more fastener components being located within the notch such that the base at least partially resides within the attachment channel when the drawer housing is secured to the attachment point,

a lock for securing a drawer within the interior volume,

a processor for controllably locking and unlocking the lock, and

a memory for storing one or more stored passcode values for unlocking the lock;

the drawer that includes one or more compartments and is slidably movable with respect to the interior volume of the drawer housing between

a closed position in which the compartments are inaccessible, and

an open position in which the compartments are at least partially accessible;

a drawer catch for releasing the drawer from the interior volume of the drawer housing when the drawer is in the open position; and

an access pad mounted to an exterior surface of the drawer housing, the exterior surface being parallel to an access along which the drawer is slidably movable with respect to the interior volume of the drawer housing,

where the access pad enables a user to enter a passcode, and

where the processor is configured to unlock the lock when the passcode matches one of the one or more stored passcode values in the memory.

9. The drawer assembly of claim 8, wherein the base is part of a mobile cart structure or a wall.

10. The drawer assembly of claim 8, wherein the memory further comprises:

a time threshold for how long the drawer is able to remain in an unlocked state,

where the lock is configured to lock if the time threshold is reached.

11. The drawer assembly of claim 8, further comprising:

one or more covers,

wherein each cover is associated with at least one of the compartments, and

wherein each cover is openable to provide access to the corresponding at least one compartment when the drawer is in the open position.

12. The drawer assembly of claim 11, wherein each cover is translucent or clear, which enables the user to determine if there are contents within each compartment.

13. The drawer assembly of claim 11, further comprising:

a data port that is connected to the processor and capable of interfacing with an external computer.

14. The drawer assembly of claim 13, wherein the memory includes instructions, which, when executed by the processor, cause the processor to:

establish a communication channel between the drawer assembly and the external computer via the data port;

receive information from the external computer at the data port; and

store at least some of the information in the memory.

15. The drawer assembly of claim 14, wherein the information includes acceptable passcode values for unlocking the drawer housing.

16. The drawer assembly of claim 13, wherein the memory includes instructions, which, when executed by the processor, cause the processor to:

establish a communication channel between the drawer assembly and the external computer via the data port; and

transfer information from the drawer assembly to the external computer through the data port.

17. The drawer assembly of claim 16, wherein the information includes time stamps corresponding to openings or closings of the drawer, entered passcode values, or both.

18. The drawer assembly of claim 11, wherein the access pad comprises any of a keypad, a card reader, a fingerprint scanner, a retina scanner, and a facial recognition system.

19. The drawer assembly of claim 11, wherein the drawer housing includes a lower surface and an upper surface that are interlock-able and stackably mountable upon other drawer housings.

20. A drawer assembly comprising:

a drawer housing defined by an upper surface and opposite sides extending downwardly from the upper surface, the drawer housing having

an opening that extends inward from a front end of the drawer housing to define an interior volume, and

a notch along a back end of the drawer housing to define an attachment channel;

a drawer that includes one or more compartments and is slidably movable with respect to the interior volume of the drawer housing between

a closed position in which the compartments are inaccessible, and

an open position in which the compartments are at least partially accessible;

an access pad mounted to one of the opposite sides of the drawer housing;

a lock for selectably locking and unlocking the drawer in response to entry of a passcode on the access pad; and

a fastener component for affixing the drawer housing to a base, the fastener component being located within the notch such that the base at least partially resides within the attachment channel when the drawer housing is affixed to the base.
