Abstract

Aspects of the disclosure relate to a base vehicle, including a base vehicle chassis, an upper mount assembly including at least one mounting rail attached to a top of a frame rail of the base vehicle chassis, and a lower mount assembly including at least one mounting bracket attached to a bottom of the base vehicle chassis. The at least one mounting bracket is moveable between a retracted position proximate to the frame rail and an extended position distal from the frame rail. The at least one mounting rail is configured to receive at least one mounting bracket of an upper vehicle to mount the upper vehicle on top of the base vehicle. The at least one mounting bracket is configured to attach to at least one mounting rail of a lower vehicle to mount the base vehicle on top of the lower vehicle.

First claim

What is claimed is:

1. A base vehicle, comprising:
a base vehicle chassis comprising a front axle, a rear axle, and at least one frame rail;
an upper mount assembly comprising at least one mounting rail attached to a top of the at least one frame rail of the base vehicle chassis; and
a lower mount assembly comprising at least one mounting bracket attached to a bottom of the base vehicle chassis, the at least one mounting bracket moveable between a retracted position proximate to the at least one frame rail and an extended position distal from the at least one frame rail;
wherein the at least one mounting rail is configured to receive at least one mounting bracket of an upper vehicle to mount the upper vehicle on top of the base vehicle;
wherein the at least one mounting bracket is configured to attach to at least one mounting rail of a lower vehicle to mount the base vehicle on top of the lower vehicle; and
wherein the at least one mounting rail extends along a length of the frame rail between the front axle and the rear axle.

2. The base vehicle of claim 1 , wherein the at least one mounting rail is configured to receive a vocational module for mounting on top of the base vehicle, the vocational module comprising at least one of a concrete mixer, concrete pumper, dump body, refuse body, roll-off body, or van body.

3. The base vehicle of claim 1 , wherein the at least one mounting rail comprises:
a Z-rail having an upper portion, a lower portion, and an intermediate portion extending vertically between the upper portion and the lower portion; and
at least one plate attached to the intermediate portion and an outer surface of the at least one frame rail.

4. The base vehicle of claim 1 , wherein the at least one mounting bracket comprises an L-bracket having a horizontal portion and a vertical portion.

5. The base vehicle of claim 1 , wherein the lower mount assembly comprises at least one arm subassembly comprising:
the at least one mounting bracket;
at least one telescoping arm, the at least one mounting bracket attached to the bottom of the at least one telescoping arm, the at least one telescoping arm configured to move between the retracted position and the extended position.

6. The base vehicle of claim 5 , wherein the at least one mounting bracket is pivotably mounted to the at least one telescoping arm.

7. The base vehicle of claim 1 , wherein the lower mount assembly comprises at least one body subassembly comprising:
a left-arm subassembly comprising:
a left mounting bracket of the at least one mounting bracket, the left mounting bracket comprising a left L-bracket having a left horizontal portion and a left vertical portion, the left vertical portion comprising a left pinhole;
a left telescoping arm, the left mounting bracket attached to a bottom of the left telescoping arm, the left telescoping arm configured to move between the retracted position and the extended position;

a right-arm subassembly comprising:
a right mounting bracket of the at least one mounting bracket, the right mounting bracket comprising a right L-bracket having a right horizontal portion and a right vertical portion, the right vertical portion comprising a right pinhole;
a right telescoping arm, the right mounting bracket attached to a bottom of the right telescoping arm, the right telescoping arm configured to between the retracted position and the extended position;
a horizontal tube attached to and extending between the left mounting bracket and the right mounting bracket, the horizontal tube comprising a left retractable pin extending through the left pinhole of the left mounting bracket and a right retractable pin extending through the right pinhole of the right mounting bracket.

8. The base vehicle of claim 7 , wherein the at least one body subassembly comprises a front-body subassembly positioned rearward of the front axle and a rear body subassembly positioned rearward of the rear axle.

9. The base vehicle of claim 1 ,
wherein the at least one mounting rail comprises:
a Z-rail having an upper portion, a lower portion, and an intermediate portion extending vertically between the upper portion and the lower portion; and
at least one plate attached to the intermediate portion and an outer surface of the at least one frame rail;
a first plastic pad attached to an upper surface of the upper portion of the Z-rail;
wherein the at least one mounting bracket comprises:
an L-bracket having a horizontal portion and a vertical portion; and
a second plastic pad attached to a lower surface of the horizontal portion of the L-bracket.

10. The base vehicle of claim 1 ,
wherein the at least one mounting rail comprises:
a Z-rail having an upper portion, a lower portion, and an intermediate portion extending vertically between the upper portion and the lower portion, the intermediate portion comprising at least one pinhole; and
at least one plate attached to the intermediate portion and an outer surface of the at least one frame rail;
wherein the at least one mounting bracket comprises:
an L-bracket having a horizontal portion and a vertical portion;
wherein the vertical portion comprises at least one pinhole.

11. The base vehicle of claim 1 , further comprising a plurality of leg assemblies comprising a front set of two leg assemblies and a rear set of two leg assemblies, each leg assembly comprising:
a telescoping leg attached to the base vehicle chassis;
a leg actuator attached to a top of the telescoping leg; and
a wheel attached to a bottom of the telescoping leg,
wherein the leg actuator moves the telescoping leg between
a retracted position, where wheels of the base vehicle contact a ground;
an extended position, where wheels of the base vehicle are lifted off the ground.

12. The base vehicle of claim 11 , wherein the front set of two leg assemblies are positioned rearward of the front axle of the base vehicle chassis, and the rear body set of two leg assemblies are positioned rearward of the rear axle of the base vehicle chassis.

13. The base vehicle of claim 1 , further comprising at least one winch attached at a rear of the base vehicle chassis, the at least one winch comprising a drum, and a winch cable wrapped around the drum.

14. The base vehicle of claim 13 , further comprising at least one pulley configured to receive the winch cable.

15. The base vehicle of claim 1 , further comprising:
a left winch attached at a rear of the base vehicle chassis, the left winch comprising a left drum and a left winch cable wrapped around the left drum;
