AI Technical Summary

Benefits of technology

"The present invention is about improving gas cylinders, such as scuba cylinders, medical cylinders, industrial cylinders, and paintball cylinders, by adding ribs to the outside diameter of the cylinder and a valve protector for increased safety and ease of handling. The gas cylinder may also be attached to a wheel support for easy movement. The technical effects of the invention include better structure design, protection from damage, and improved safety when using gas cylinders."

Problems solved by technology

Steel, however, has some disadvantages, for example, steel is heavier than aluminum, steel rusts, and although the exterior can be galvanized to prevent corrosion, the interior cannot because the zinc used in the galvanizing process may adversely affect gas purity.
These advantages, however, are more than offset by the fact that aluminum is a relatively soft metal whose malleable properties make it susceptible to denting and gouging.
Damage can also result when gas cylinders roll and hit against one another.
Because of this “rolling” tendency, gas cylinders may be placed in a fabric or plastic sleeve; however, the use of such sleeves does not always prevent the tanks from becoming severely damaged.
This makes them difficult to grasp and carry.
Accordingly, when they are moved from one location to another, the tendency is to hoist and carry them by the valve stem and this, when repeatedly done, will ultimately cause damage to the valve assembly.
However, the longitudinal channels do not prevent damage to the gas cylinder, and the handles must be molded, cast or otherwise formed into the body of the gas cylinder.

Embodiment Construction

[0023]The present invention is directed to gas cylinders such as, but not limited to, mixed gas cylinders, compressed air cylinders, oxygen cylinders, carbon dioxide cylinders and acetylene cylinders. Such gas cylinders that may be adapted with the present invention include, but are not limited to, scuba tanks, medical cylinders, industrial cylinders and paintball cylinders.

[0024]Referring now to FIG. 1, the gas cylinder 20 of the present invention includes a bottom end 22 and a top end 24 and a cylindrical wall (outside surface) disposed between the two ends so as to form the cylinder. The body 34 of the cylinder or tank is formed with raised ribs 32 that extend longitudinally from proximate the top of the cylinder to proximate the bottom of the cylinder. The longitudinal ribs may be substantially equally spaced circumferentially along the outside wall of the cylinder. As shown in FIG. 2, the body of the cylinder wall is generally hollow forming a cavity 36 within the cylinder so a...

Abstract

A gas cylinder, such as a scuba tank, is formed with raised ribs that extend longitudinally from near the top of the cylinder to near the bottom of the cylinder. The longitudinal ribs may be arcuate and equally spaced along the outside circumference of the cylinder so as to protect the body of the cylinder from damage. The gas cylinder may be made from steel or an aluminum alloy, such that the longitudinal ribs are formed by backward impact extrusion. The gas cylinder may be configured with a cylindrical neck at the top of the body so as to house a valve and valve stem. The gas cylinder may be transported using a wheeled pedestal having an adjustable strap for securing the cylinder to the pedestal. A valve protector with an optional handle and retaining clip is provided.

Description

CROSS-REFERENCES TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60 / 583,297, filed Jun. 24, 2004, the content of which is hereby incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to gas cylinders, and more particularly to mixed gas cylinders, compressed air cylinders, oxygen cylinders, carbon dioxide cylinders and acetylene cylinders.[0003]Gas cylinders, such as scuba tanks, are containers for compressed air and other gases, such as oxygen and carbon dioxide. Many gas cylinders are equipped at the top with a valve for regulating gas flow, and the type of a valve will depend on its intended use. Generally, gas cylinders are made of aluminum and / or steel. A steel cylinder is stronger and it can hold more gas per cubic foot than an aluminum cylinder. Steel, however, has some disadvantages, for example, steel is heavier than aluminum, steel rusts, and although the exterior can b...
