Abstract

An attachment structure for attaching to the side panels of a pickup truck a toolbox of the type having a lower part positioned within the bed of the pickup truck, a top part which is longer than the lower part and overhangs the side panels and a shelf interconnecting the lower and upper parts. The attachment structure secures the toolbox to the side panels without the need to drill holes into the tops of the side panels. A retainer plate is slidable through an end wall of the lower part of the toolbox between a retracted position mostly within the toolbox and an extended position mostly outside of the toolbox. A threaded bolt engages this retainer plate to urge it upwardly against an inner portion of the side panel which projects inwardly over the retainer plate.

Claims

1. In combination, a toolbox mountable on side panels of a pickup truck bed and an attachment means for securing the toolbox to the side panels, wherein the toolbox has a lower part of a first length, taken in a direction transversely across the pickup truck bed, which fits down between the side panels of the bed, a longer upper part which extends over the tops of the side panels of the pickup truck bed and a shelf extending from the top of the end of the lower part to the bottom of the end of the upper part, and wherein the side panels of the pickup truck each include an inner portion which projects inwardly from a main vertical wall portion of each side panel,

said attachment means including a first member extending from inside of the toolbox out through the end of the lower part and beneath the said inner portion of the side panel, and a second member interconnecting the first member and said shelf and urging the first member against the bottom of the inner portion, squeezing the inner portion between the first member and the shelf, to secure the toolbox to the pickup truck bed.

2. The invention of claim 1, wherein the attachment means includes a plate having a first end located within the lower part of the toolbox and a second end located outside of the toolbox, beneath the said inner portion, and said second member urging the plate against the bottom of the inner portion.

3. The invention of claim 2, the second member including threaded bolt means which engage both the shelf and the plate to urge the plate toward the shelf.

4. The invention of claim 2, wherein said plate has at least one slot, elongated in a direction from the first end to the second end, the bolt engagable in the slot to permit varying the position of the bolt along the slot.

5. The invention of claim 4, wherein each plate has two parallel slots, each having a said bolt passing therethrough.

6. The invention of claim 2, the top surface of the plate being serrated to facilitate securely engaging the bottom of the inner portion.

7. The invention of claim 2, said attachment means being moveable between a retracted storage position in which the plate is substantially within the lower part of the toolbox and an extended operative position at which substantially all of the plate is located outside of the toolbox.

8. The invention of claim 7, the plate having elongated slots, elongated in the direction of movement of the plate between the retracted and extended positions, the second member engaging the plate through the slots, wherein the plate is moveable relative to the second member, between said positions.

9. The invention of claim 8, said second member being a threaded bolt means for each slot, said threaded bolt means engaging both the shelf and the plate to urge the plate toward the shelf, the bolt means being adjustable to hold the plate closer to the shelf in the retracted position and further from the shelf in the extended position.
