Abstract

A cargo bed assembly for a pickup truck includes: a pair of side walls opposing each other; a truck bed located between the pair of sidewalls, and having a first cavity; a tailgate pivotally connected to a rear end of the truck bed by a first pivot pin, and having a second cavity; a slide unit movably received in the first cavity; and a step unit movably received in the second cavity. In particular, the second cavity is configured to communicate with the first cavity, and the step unit is pivotally connected to the slide unit.

First claim

What is claimed is:

1. A cargo bed assembly for a pickup truck, the cargo bed assembly comprising:
a pair of sidewalls opposing each other;
a truck bed located between the pair of sidewalls, and having a first cavity;
a tailgate pivotally connected to a rear end of the truck bed by a first pivot pin, and having a second cavity;
a slide unit movably received in the first cavity; and
a step unit movably received in the second cavity,
wherein:
the second cavity is configured to communicate with the first cavity, and
the step unit is pivotally connected to the slide unit.

2. The cargo bed assembly according to claim 1 , wherein the slide unit includes:
a slide plate having a front end facing a front of the pickup truck and a rear end facing a rear of the pickup truck, and
a support plate pivotally connected to the front end of the slide plate by a second pivot pin.

3. The cargo bed assembly according to claim 2 , wherein the slide plate is configured to move between a stowed position in which the slide plate is stowed in the first cavity and an extended position in which the slide plate is extended from the first cavity and the second cavity.

4. The cargo bed assembly according to claim 3 , wherein the support plate is held in the tailgate by a pair of hold mechanisms when the slide plate is fully extended from the first cavity and the second cavity.

5. The cargo bed assembly according to claim 4 , wherein:
the support plate includes a pair of accommodation recesses provided in both opposing sides thereof, and
each hold mechanism of the pair of hold mechanisms is received in a corresponding accommodation recess among the pair of accommodation recesses.

6. The cargo bed assembly according to claim 5 , wherein each hold mechanism of the pair of hold mechanisms includes a hold member pivotally mounted in the corresponding accommodation recess and a spring biasing the hold member outward from the support plate.

7. The cargo bed assembly according to claim 6 , wherein:
the tailgate has a pair of hold recesses provided in both opposing sides of the second cavity, respectively, and
the hold member is fitted into a corresponding hold recess by the spring.

8. The cargo bed assembly according to claim 2 , wherein the step unit is configured to move between a stowed position in which the step unit is stowed in the second cavity and an extended position in which the step unit is fully extended from the second cavity.

9. The cargo bed assembly according to claim 8 , wherein the step unit includes a step support pivotally connected to the rear end of the slide plate by a third pivot pin, and a step member pivotally connected to the step support.

10. The cargo bed assembly according to claim 9 , wherein:
the step support includes a pair of support legs spaced apart from each other, and
the pair of support legs extend from the step support.

11. The cargo bed assembly according to claim 10 , wherein:
the step member is pivotally connected to the pair of support legs by a fourth pivot pin, and
as the step member pivots, the step member is configured to move between a folded position in which the step member is folded to the step support and an unfolded position in which the step member is unfolded from the step support.

12. The cargo bed assembly according to claim 11 , wherein:
the step member has a first end portion close to the fourth pivot pin and a second end portion further away from the fourth pivot pin compared to the first end portion,
the first end portion has a grip recess,
a pair of support protrusions are provided on opposing edges of the first end portion, and
each support protrusion of the pair of support protrusions has a stopper surface configured to regulate the unfolded position of the step member.

13. The cargo bed assembly according to claim 12 , wherein:
the step support has a recess located between the pair of support legs,
the second end portion has a protrusion, and
the protrusion of the second end portion is received in the recess of the step support when the step member is in the folded position.

14. The cargo bed assembly according to claim 1 , wherein:
the tailgate includes a first opening and a second opening configured to communicate with the second cavity,
the first opening and the second opening are provided in both opposing ends of the second cavity, respectively,
the first opening faces the first cavity,
the second opening faces an outside of the pickup truck, and
a first cover is pivotally mounted to the second opening.

15. The cargo bed assembly according to claim 14 , wherein the tailgate further includes a third opening adjacent to the second opening, and
a second cover is pivotally mounted to the third opening.
