## Title
Air tank running boards

## Abstract

The present invention is an air tank running board. The running boards are tubular and the running boards also double as compressed air tanks. Each running board is provided with a hollow interior that is sealed at one end and has a 1⁄4 NPT threaded pipe on its opposite end that communicates between the hollow interior of the tank and the exterior of the tank. The threaded pipe of each running board is connected to a mounted manifold with regulator so that the running board tanks can be pressurized to a desired pressure. The tubular running boards can be used as steps or step structures can be added to them.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority to U.S. Provisional Patent Application No. 62/198,338 for Air Tank Running Boards filed on Jul. 29, 2015.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to running boards for attachment to a vehicle such as a pickup truck. More specifically, the invention relates to hollow running boards that also serve as air tanks. The air tanks are attached to a mounted manifold with regulator so that the air pressure within the hollow air tanks of the running boards can be controlled and so that air pressure can be used to air up tires or for other purposes when needed.
2. Description of the Related Art
Although air compressors can be mounted onto a vehicle to provide compressed air when needed, often it would be desirable just to have sufficient compressed air in order to air up a tire rather than go to the expense and trouble of having a dedicated compressor on the vehicle. And although a compressed air tank could be carried in a vehicle or mounted underneath a vehicle, this would be added expense and weight.
The present invention addresses this need by providing tubular running boards that also double as compressed air tanks. Each running board is provided with a hollow interior that is sealed at one end and has a 1⁄4 NPT threaded pipe on its opposite end that communicates between the hollow interior of the tank and the exterior of the tank. The threaded pipe of each running board is connected to a mounted manifold with regulator so that the running board tanks can be pressurized to a desired pressure.
SUMMARY OF THE INVENTION
The present invention are air tank running boards. The running boards are tubular and the running boards that also double as compressed air tanks. Each running board is provided with a hollow interior that is sealed at one end and has a 1⁄4 NPT threaded pipe on its opposite end that communicates between the hollow interior of the tank and the exterior of the tank. The threaded pipe of each running board is connected to a mounted manifold with regulator so that the running board tanks can be pressurized to a desired pressure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings and initially to FIG. 1, there is illustrated an air tank running board 10 that is constructed in accordance with a preferred embodiment of the present invention. The air tank running board 10 that is shown in FIG. 1 is provided with miter-cut steps 12.
Referring to FIG. 2, a first alternate embodiment air tank running board 10A is shown that has a square cut step 12A′ and also a pipe or plate 12A′′ that is welded onto the running board 10A for a second step.
Referring to FIG. 3 a second alternate embodiment air tank running board 10B is shown that has a bent tubing step 12B′ and also grip tape 12B′′ applied directly to the running board for a second step.
Although various styles of steps 12, 12A′, 12A′′, 12B′ and 12B′′ have been illustrated, the invention is not limited to these specific styles. Also, although the drawings illustrate only two steps 12, 12A′, 12A′′, 12B′ and 12B′′ attached to each cylindrical tube 14, the invention is not so limited and additional steps 12, 12A′, 12A′′, 12B′, 12B′′, etc. can be employed on each tube 14. Also, a cylindrical tube 14 can be provided with only one step, if desired.
Each of the air tank running boards 10, 10A and 10B that are shown in FIGS. 1-3 is constructed of the cylindrical tube 14 that is provided with mounting brackets 16 for mounting the running board 10, 10A and 10B to a vehicle (not illustrated). The cylindrical tube 14 of each of the running boards 10, 10A and 10B also doubles as a compressed air tank. Each cylindrical tube 14 is provided with a hollow interior that is sealed at one end 18 and has a 1⁄4 NPT threaded pipe 20 on its opposite second end 22 that communicates between the hollow interior of the cylindrical tube 14 and the exterior of the tube 14. Preferably attached to each threaded pipe 20 is a shut-off valve 24 for isolating the tube 14 from the surrounding air.
As shown in FIG. 4, the threaded pipe 20 of each running board 10, 10A and 10B is connected via air line 26 to a manifold 28 with regulator 30 that is mounted on the vehicle. In the arrangement shown in FIG. 4, the running boards 10, 10A and 10B are mounted on either side of the vehicle and the running board tubes 14 can be pressurized to a desired pressure via the manifold 28. The manifold 28 may be provided with an air supply line 32 that can be connected to an air compressor (not illustrated) for filing the tubes 14 with compressed air.
While the invention has been described with a certain degree of particularity, it is manifest that many changes may be made in the details of construction and the arrangement of components without departing from the spirit and scope of this disclosure. It is understood that the invention is not limited to the embodiments set forth herein for the purposes of exemplification, but is to be limited only by the scope of the attached claim or claims, including the full range of equivalency to which each element thereof is entitled.
