Abstract

A multi-pocket step-drawer is disclosed that includes a dispensing drawer and a control module. The dispensing drawer has a body comprising at least one fixed wall forming at least two open-top compartments that are arranged along an axis parallel to the front-to-back axis and a ladder fixedly coupled to the body. The ladder has a plurality of cross arms arranged along an axis parallel to the front-to-back axis. The control module includes a housing and a latching element coupled to the housing and disposed proximate to the ladder. The latching element has a first position wherein the latching element engages one of the plurality of cross-arms so as to prevent the dispensing drawer from moving toward the front and a second position wherein the latching element allows the dispensing element to move toward the front.

Claims

1. A step-drawer comprising:

a dispensing drawer having a front and a front-to-back axis, the dispensing drawer comprising;

a body comprising at least one fixed wall forming at least two open-top compartments that are arranged along an axis parallel to the front-to-back axis; and

a ladder fixedly coupled to the body, the ladder comprising a plurality of cross-arms arranged along an axis parallel to the front-to-back axis; and

a control module comprising;

a housing; and

a latching element coupled to the housing and disposed proximate to the ladder, the latching element having a first position wherein the latching element engages one of the plurality of cross-arms so as to prevent the dispensing drawer from moving toward the front and a second position wherein the latching element allows the dispensing drawer to move toward the front.

2. The step-drawer of claim 1, wherein the dispensing drawer and control module are configured such that the dispensing drawer moves with respect to the control module solely along an axis parallel to the front-to-back axis.

3. The step-drawer of claim 2, wherein the dispensing drawer and control module are aligned with each other along an axis parallel to the front-to-back axis.

4. The step-drawer of claim 3, wherein a portion of one of the dispensing drawer and control module extends in a direction parallel to the front-to-back axis so as to overlap the other of the dispensing drawer and control module.

5. The step-drawer of claim 4, wherein:

the body of the dispensing drawer comprises a back end;

the ladder extends from the back end of the body and into the control module; and

the latching element is disposed with the housing.

6. The step-drawer of claim 4, wherein:

the housing of the control module comprises a front end;

the control module further comprises a tab fixedly coupled to the housing, the tab extending from the front end of the housing and adjacent to the dispensing drawer, the tab comprising a front end; and

the latching element is coupled to the tab proximate to the front end of the tab.

7. The step-drawer of claim 6, wherein:

the body of the dispensing drawer comprises a bottom;

the ladder is disposed on the bottom; and

the tab extends adjacent to the bottom.

8. The step-drawer of claim 1, further comprising:

a sensor configured to sense an attribute being one of a position and a displacement of the dispensing drawer relative to the control module, the sensor further configured to provide a signal comprising information related to the sensed attribute.

9. The step-drawer of claim 1, further comprising:

an actuator coupled to the latching element and the housing, the actuator configured to selectively move the latching element between the first and second positions.

10. The step-drawer of claim 1, wherein all electrical devices are disposed within the housing of the control module.

11. The step-drawer of claim 1, wherein there are no electrical wire coupled between the dispensing drawer and the control module.

12. The step-drawer of claim 1, further comprising:

a plurality of lids hingedly coupled to the body, the plurality of lids configured to respectively cover at least a portion of the plurality of open-top compartments.

14. The assembly of claim 12, wherein the dispensing drawer and control module are configured such that the dispensing drawer moves with respect to the control module solely along an axis parallel to the front-to-back axis.

15. The assembly of claim 14, wherein the dispensing drawer and control module are aligned with each other along an axis parallel to the front-to-back axis.

16. The assembly of claim 15, wherein a portion of one of the dispensing drawer and control module extends in a direction parallel to the front-to-back axis so as to overlap the other of the dispensing drawer and control module.

17. The assembly of claim 16, wherein:

the body of the dispensing drawer comprises a back end;

the ladder extends from the back end of the dispensing drawer and into the control module; and

the latching element is disposed with the housing.

18. The assembly of claim 16, wherein:

the housing of the control module comprises a front end;

the control module further comprises a tab fixedly coupled to the housing, the tab extending from the front end of the control module and adjacent to the dispensing drawer, the tab comprising a front end; and

the latching element is coupled to the tab proximate to the front end of the tab.

19. The assembly of claim 18, wherein:

the body of the dispensing drawer comprises a bottom;

the ladder is disposed on the bottom; and

the tab extends adjacent to the bottom.

20. The assembly of claim 12, further comprising:

a sensor configured to sense an attribute being one of a position and a displacement of the dispensing drawer relative to the control module, the sensor further configured to provide a signal comprising information related to the sensed attribute.

21. The assembly of claim 12, further comprising:

an actuator coupled to the latching element and the housing, the actuator configured to selectively move the latching element between the first and second positions.

22. The assembly of claim 12, further comprising:

a plurality of lids hingely coupled to the body, the plurality of lids configured to respectively cover at least a portion of the plurality of open-top compartments.

13. A step-drawer assembly comprising:

a plurality of step-drawers each comprising;

a dispensing drawer having a front and a front-to-back axis, the dispensing drawer comprising a body comprising at least one fixed wall forming at least two open-top compartments that are arranged along an axis parallel to the front-to-back axis and a ladder fixedly coupled to the body, the ladder comprising a plurality of cross-arms arranged along an axis parallel to the front-to-back axis; and

a control module comprising a housing and a latching element coupled to the housing and disposed proximate to the ladder, the latching element having a first position wherein the latching element engages one of the plurality of cross-arms so as to prevent the dispensing drawer from moving toward the front and a second position wherein the latching element allows the dispensing element to move toward the front; and
