Abstract

A modular housing assembly is stacked in a vertical array of similar assemblies within a multi-drawer storage unit. A modular housing assembly includes a housing and a linear channel extending though opposite ends of the housing. The channel opens into the interior of the housing. Two bar end modules slide along the channel. The end modules may be connected to bar spacers cut from separate pieces to form assembled sliding bars. An actuator, including a fork and a cam, is provided to lock the sliding bars to prevent more than one drawer from opening at one time. The actuator rotates within the housing, about a pin mounted between two walls of the housing. A modular housing and a kit for installing a modular housing assembly are also described.

Claims

1. A housing assembly for use in a multi-compartment storage unit, the storage unit comprising a plurality of stacked sliding drawers, wherein each of the sliding drawers is slidably mounted on a pair of slides for withdrawal from the storage unit, and the storage unit comprises a plurality of like housing assemblies in an abutting linear array, the plurality of like housing assemblies comprising a plurality of slide bars within the linear array, and a stop limiting displacement of the slide bars in the linear array to a predetermined distance, each like housing assembly being operatively associated with one of the sliding drawers, the housing assembly comprising:

a housing defining a linear channel extending along a first axis and opening at opposite ends of the housing;

a pair of opposing sliding bar assemblies comprising sliding bar ends located within opposite ends of the channel;

an actuator operatively associated with one of the sliding drawers, the actuator being located intermediate the opposing sliding bar ends, the actuator operating between first and second positions, wherein in the first position, the actuator permits displacement of the sliding bar ends within the linear channel upon withdrawal of the associated drawer from the storage unit, and in the second position the actuator engages at least one of the opposing sliding bar ends to inhibit displacement of the sliding bar ends within the linear channel; and

a mounting member securing the actuator to the housing in a predetermined operative location relative to the sliding bar ends.

2. The housing assembly in claim 1 wherein the mounting member defines a second axis perpendicular to the first axis, and the actuator rotates about the second axis, between the first and second positions.

3. In the housing assembly as claimed in claim 2, the pair of opposing sliding bar ends, when abutting, define an enclosed space bounded by a first bearing surface and a second bearing surface opposing the first bearing surface, and the actuator comprises a cam defining a first and second opposing longitudinal surface and a first and second transverse surface, the cam being centrally positioned within the enclosed space when the actuator is in the first position.

4. In the housing assembly as claimed in claim 3, the first and second transverse surfaces engaging the first and second bearing surfaces when the actuator is in the second position.

5. The housing assembly of claim 1 wherein the actuator operates between said first and second positions and a third position, wherein in the second position the actuator bears against both of the opposing sliding bar ends, and in the third position the actuator bears against at least one of the opposing slide bar ends upon withdrawal of an unassociated drawer, and the actuator returning to the first position upon closure of the unassociated drawer.

6. In the housing assembly as claimed in claim 5, at least one of the first and second longitudinal surfaces engaging at least one of the first and second bearing surfaces when the actuator is in the third position.

7. In the housing assembly as claimed in claim 6, the first and second longitudinal surfaces engaging the first and second bearing surfaces when the actuator is in the third position.

8. In the housing assembly as defined by claim 3, the housing defining an aperture for securing the mounting member to the housing.

9. In the housing assembly as defined by claim 8, the aperture defining an elongated slot having first and second distal ends;

the mounting member is centrally located along the slot when the actuator rotates between the first and second positions; and

the mounting member is displaced to a position adjacent to one of the first and second distal ends of the elongated slot when the actuator is in the third position.

21. The housing assembly as claimed in claim 1, comprising a pair of bar spacers, one of the spacers being secured to a corresponding one of the sliding bar ends.

22. The housing as claimed in claim 21 wherein the bar spacers are made from a first material and the sliding bar ends are made from a second material differing from the first material.

10. A housing for use in a multi-compartment storage unit, the housing comprising:

a plurality of outer walls defining an inner chamber, a first wall being of a lower height relative to a second wall, the first wall defining a first aperture and the second wall defining a second aperture, for receiving an axial mounting member extending through the inner chamber between the first and second apertures;

the housing defining a linear channel extending through the inner chamber, the channel opening at opposite ends of the housing and defining a first axis;

the first and second apertures being positioned along a second axis, the second axis being perpendicular to the first axis; and

at least one fastening element for securing the housing to the multi-compartment storage unit.

11. In the housing claimed in claim 10, the channel opening into the inner chamber.

12. In the housing claimed in claim 11, the second wall defining a wall of the linear channel, and the channel extending along a longitudinal axis defined by the second wall.

13. In the housing claimed in claim 12, the housing comprising spaced apart abutments projecting from two opposing walls of the housing, inwardly toward the chamber, the abutments extending along the channel.

14. The housing claimed in claim 13, comprising a second linear channel exterior of the chamber, the second channel being parallel to the first channel.

15. The housing claimed in claim 10, wherein the housing is made from a single work piece.

16. A kit comprising a pair of sliding bar assemblies, an actuator, a housing, and an axial mounting member, the housing comprising:

a plurality of outer walls defining an inner chamber, a first wall being of a lower height relative to a second wall, the first wall defining a first aperture and the second wall defining a second aperture, for receiving the axial mounting member extending through the inner chamber between the first and second apertures;

the housing defining a linear channel extending through the inner chamber, the channel opening at opposite ends of the housing and defining a first axis;

the first and second apertures being positioned along a second axis, the second axis being perpendicular to the first axis; and

at least one fastening element for securing the housing to the multi-compartment storage unit.

17. The kit claimed in claim 16, wherein a first sliding bar end of a first sliding bar assembly is configured for sliding movement along a first end of the channel, a second sliding bar end of a second sliding bar assembly is configured for sliding movement along a second end of the channel, the sliding bar ends each defining an enclosed space when the sliding bars are abutting, the space enclosing a cam defined by the actuator.

18. The kit as claimed in claim 17, wherein the actuator comprises a fork defining an engagement channel extending along a first longitudinal axis, the first longitudinal axis being inclined to a second longitudinal axis defined by the cam.

19. The kit as claimed in claim 18, the fastening element comprising a mounting track defining a plurality of predefined positions for securing the housing relative to the mounting track.

20. The kit as claimed in claim 19, wherein in the housing, the channel extends along the second wall and the channel opens into the inner chamber.
