Abstract

A smooth operating cargo box which is simply and easily assembled by first erecting the side panels on the box base by engaging outwardly opening end hooks extending along the bottom edges of the sides with inwardly opening side hooks extending along the side edges of the base, then erecting the back panel by sliding it in a direction perpendicular to the plane of the panel toward the rear of the container to engage outwardly open end hooks along the side and bottom edges of the back panel with inwardly directed side hooks extending along the rear edges of the base and side panels, then erecting the front panel by engaging an outwardly opening end hook extending along the bottom edge of the panel with an inwardly opening side hook extending along the front edge of the base and rotating the panel around its bottom edge from inside toward the outside of the container to engage inwardly opening end hooks along the side edges of the front with outwardly opening side hooks extending along the front edges of the sides, and finally sliding the top panel in the direction of its plane from the rear toward the front of the box to engage inwardly opening end hooks along the sides of the top with outwardly opening side hooks on the top edges of the sides and to engage an inwardly opening side hook along the back edge of the top with an outwardly opening end hook extending along the top edge of the back panel. Latches are provided for clamping the front edge of the top to the top edge of the front. An alarm system gives a signal in the event that an unauthorized person attempts either to open the container or to break through a panel thereof in an effort to gain access to the contents.

Claims

1. A smooth operating cargo box including in combination a base, side panels, a back panel, a front panel and a top panel, first interengageable means running along the side edges of said base and along the bottom edges of the side panels for connecting said side panels to said base, second interengageable means along the bottom and side edges of the back panel and along the back edge of the base and back edges of the side panels, said second interengageable means comprising respective inwardly opening side hooks running along the back edges of said side panels and outwardly opening end hooks running along the side edges of the back panel, said second interengageable means being responsive to sliding movement of the back panel from the inside toward the outside of said box in a direction perpendicular to the plane of the back panel to bring said end hooks into engagement with said side hooks to connect the back panel to the base and side panels, third interengageable means along the bottom and side edges of the front panel and along the front of the base and front edges of the side panels responsive to pivotal movement of the front panel around its bottom edge in a direction from outside toward the inside of said box for connecting said front panel to said base and interengaging the front panel with the side panels, and fourth interengageable means along the back and side edges of the top panel and along the top edge of the back panel and top edges of the side panels responsive to sliding movement of said top panel in the direction of the plane thereof from back to front of said box for connecting said top panel to said back and side panels.

2. A cargo box as in claim 1 in which said third interengageable means comprises outwardly opening side hooks running along the front edges of the side panels and inwardly opening end hooks running along the side edges of the front panel.

3. A cargo box as in claim 1 in which said fourth interengageable means comprises outwardly opening side hooks running along the upper edges of said side panels and inwardly opening end hooks running along the side edges of said top panel.

4. A cargo box as in claim 3 in which said fourth interengageable means comprises an inwardly opening side hook running along the rear edge of said top panel and an outwardly opening end hook running along the top edge of the back panel.

5. A cargo box as in claim 4 including a latch for securing the front edge of the top panel to the top edge of the front panel.

6. A cargo box as in claim 1 in which said third interengageable means comprises outwardly opening side hooks running along the front edges of the side panels and inwardly opening end hooks running along the side edges of the front panel and in which said fourth interengageable means comprises outwardly opening side hooks running along the upper edges of the side panels and inwardly opening end hooks running along the side edges of said top panel.

7. A cargo box as in claim 6 in which said fourth interengageable means comprises an inwardly opening side hook running along the rear edge of said top panel and an outwardly opening end hook running along the top edge of the back panel.

8. A cargo box as in claim 7 including a latch for holding the front edge of the top panel down on the top edge of the front panel.
