Abstract

The present disclosure concerns a coupling mechanism for detachably attaching two or more utility modules to one another, utility assembles, mobile carriers and other attachable modules and articles.

First claim

What is claimed is:

1. A container assembly comprising:
a first container comprising:
a first lid pivotally attached to the first container;
a first female coupler at a top face of the first lid;
a first front face, a first side face, an second side face opposite the first side face, the first front face, the first side face, and the second side face collectively partially defining a storage compartment;
a first corner extending between the first front face and the first side face, and a second corner extending between the first front face and the second side face;
a first corner bumper extending outward from the first corner; and
a second corner bumper extending outward from the second corner;
wherein the first corner bumper defines an outer surface that extends past and faces away from each of the first front face and the first side face, and wherein the second corner bumper defines an outer surface that extends past and faces away from each of the first front face and the second side face; and
a first locking latch arresting location; and

a second container comprising:
a male coupler extending from a bottom face of the second container, the male coupler configured to slidingly engage with the first female coupler of the first container, wherein the first female coupler and male coupler engage each other when the first and second containers are slid with respect to each other;
a second lid pivotally attached to the second container; and
a locking latch positionable in a locked position engaging the first locking latch arresting location thereby limiting sliding displacement of the first container with respect to the second container;

wherein the first female coupler comprises two sidewalls, a back wall, and a first rib, the back wall located between the two sidewalls, the two sidewalls and the back wall projecting above a depressed surface of the top face of the first lid, and the first rib extending away from the back wall in a first direction towards the first front face of the first container;
wherein the second container comprises a second female coupler at a top face of the second lid, the second female coupler comprising two sidewalls, a back wall, and a second rib, the back wall located between the two sidewalls, the two sidewalls and the back wall projecting above a depressed surface of the top face of the second lid, and the second rib extending away from the back wall towards a front face of the second container and the first front face of the first container; and
wherein the first container defines a width axis parallel to the first front face of the first container and the second container defines a width axis parallel to the first front face of the first container, wherein the width axis of the second container is approximately one-half the width axis of the first container.

2. The container assembly of claim 1 , the first container comprising:
a first rear wall opposite the first front face;
a pair of rear wheels extending past the first rear wall; and
a telescoping handle extending upwards from the first rear wall of the first container.

3. The container assembly of claim 2 , wherein the first female coupler of the first container and the male coupler of the second container engage each other when the first and second containers are slid with respect to each other along a sliding path defined by the first female coupler and the male coupler.

4. The container assembly of claim 3 , wherein the sliding path is perpendicular to the first front face and the first rear wall.

5. The container assembly of claim 1 , the second container comprising:
a second front face, a third side face, and a fourth side face opposite the third side face;
a third corner extending between the second front face and the third side face;
a fourth corner extending between the second front face and the fourth side face;
a third corner bumper extending outward from the third corner, wherein the third corner bumper defines an outer surface that extends past and faces away from each of the second front face and the third side face; and
a fourth corner bumper extending outward from the fourth corner, wherein the fourth corner bumper defines an outer surface that extends past and faces away from each of the second front face and the fourth side face.

6. The container assembly of claim 1 , wherein the first locking latch arresting location is defined by the first lid of the first container, and wherein the first locking latch arresting location defines a primary longitudinal axis that extends parallel to the first front face of the first container.

7. The container assembly of claim 1 , the first container comprising a plurality of female couplers including the first female coupler, each of the plurality of female couplers at the top face of the first lid, wherein the plurality of female couplers comprise four female couplers comprising a front row of at least two female couplers aligned with each other in a direction parallel to the first front face of the first container and a rear row of at least two female couplers aligned with each other in the direction parallel to the first front face of the first container.

8. The container assembly of claim 1 , the first container comprising a first toggle locking latch configured to latch the first lid of the first container in a closed position, and a second toggle locking latch configured to latch the first lid of the first container in a closed position, and the second container comprising a third toggle locking latch configured to latch the second lid of the second container in a closed position, and a fourth toggle locking latch configured to latch the second lid of the second container in a closed position.

9. The container assembly of claim 8 , wherein the locking latch is coupled to the second container between the second toggle locking latch and the fourth toggle locking latch.

10. The container assembly of claim 1 , wherein the first locking latch arresting location is defined by the first lid of the first container, and wherein the first locking latch arresting location defines a primary longitudinal axis that extends parallel to the first front face of the first container.

11. The container assembly of claim 1 , wherein the locking latch is spring biased to engage with the first locking latch arresting location.

12. The container assembly of claim 1 , the first container comprising a first tiltable carrying handle coupled to the first side face, and the second container comprising a second tiltable carrying handle coupled to a side face of the second container.

13. The container assembly of claim 1 , wherein the first locking latch arresting location is a recess defined in an upward facing surface of the top face of the first lid.

14. The container assembly of claim 13 , wherein the recess comprises a front wall, a rear wall and a bottom wall extending between the front wall and the rear wall, wherein a lower face of the locking latch faces the bottom wall of the recess when the locking latch is in the locked position.

15. A container assembly comprising:
a first container comprising:
a first lid pivotally attached to the first container;
a first female coupler at a top face of the first lid;
a first front face, a first side face, an second side face opposite the first side face, the first front face, the first side face, and the second side face collectively partially defining a storage compartment;
a first corner extending between the first front face and the first side face, and a second corner extending between the first front face and the second s
