The field of the present invention relates generally to apparatus for safely transporting cylindrical tanks, such as propane tanks, for example, and more particularly relates to carriers or holders for transporting cylindrical tanks in a horizontal position relative to the longitudinal axis thereof.
It is important that cylindrical tanks used for retaining liquids and gases, such as, for example, propane, hydrogen, oxygen, nitrogen, helium, and so forth, be transported in a safe and convenient manner. The cylindrical tanks must be transported in a manner to prevent their movement in the transport vehicle. Smaller tanks, such as propane tanks for use by homeowners, are often transported by homeowners in the trunk of an automobile. Because of the height of the propane tanks, and similar tanks, they must be positioned horizontally with respect to their longitudinal axes in the trunk of the car, and much care must be taken by the driver to ensure that the tanks are secured in a manner to prevent their rolling around in the trunk as the automobile is driven. Known carriers and holders for propane tanks, and other cylindrical tanks are generally for retaining the tanks vertically relative to their longitudinal axes, and are therefore not applicable for use in the trunk of automobiles for retaining cylindrical tanks during transport. As a result, an individual transporting a propane or similar tank via automobile may be forced to secure the tank between the front seat and dashboard of a vehicle, or in some manner between the front and rear seats, perhaps even resorting to securing the tank with rope. Regardless, in order to ensure safety, and prevent damage to the cylindrical tanks being transported or to the vehicles transporting them, there is a need in the art to provide apparatus or devices for permitting such tanks to be secured in the beds of trucks, and the trunks of automobiles during transport.
It is an object of the present invention to provide a carrier or holder for cylindrical tanks, such as propane tanks, for example, to ensure that the tanks are secured in position and prevented from moving around or rolling within the trunk of an automobile or bed of a truck.
Another object of the invention is to provide a cylindrical tank carrier or holder for retaining such tanks in a fixed horizontal position during transport.
Another object of the invention is to provide an inexpensive and relatively lightweight carrier or holder for cylindrical tanks to secure them in place during transport in a vehicle.
A further object of the invention to provide a carrier or holder for safely and securely transporting cylindrical cylinders, such as propane tanks, in a horizontal orientation, whereby the carrier or holder is compact, easy to carry, easy to store, reliable for years of service, and requires little or no assembly for use.
With these and other objects in mind, in one embodiment of the present invention, a single piece carrier or holder is provided that includes interior spaced apart, parallel, and opposing longitudinal sidewalls that each have an inward slope or converge downward toward the bottom of the carrier. Vertically oriented front wall and back wall portions are secured between the ends of the interior sidewall portions, right and left exterior sidewall portions have their top edges secured to the top edges of the interior opposing sidewall portions, with the exterior sidewall portions each diverging downward away from the interior sidewall portions. The front wall portion is made higher than the back wall portion, in order to retain a cylindrical tank at a slight angle, with the collar typically surrounding a valve mechanism on a propane tank, for example, resting against the top edge portion of the front wall of the carrier, and portions of the exterior wall of the tank being partially held in place by contact with the sloping interior sidewalls, and further with the bottom of the tank resting against the back wall of the carrier. The exterior opposing sidewalls prevent tilting of the carrier when used to transport a cylindrical tank. The bottom portion of the carrier between the front and back walls, and the interior sidewalls is open. For purposes of rigidity, it is preferred that a solid or ribbed bottom portion be rigidly secured between the bottom edges of the interior sidewalls and their respective associated exterior sidewalls.
In another embodiment of the invention, a transport carrier or holder for transporting cylindrical tanks in a horizontal orientation is provided via a single piece of appropriate metal or plastic material formed to provide interior parallel and spaced apart sidewall portions, each of which converges downward to a solid bottom portion. Exterior sidewall portions are bent away from the top edges of the interior sidewall portions, respectively, with the exterior sidewall portions diverging downward and away from the interior sidewall portions, respectively. A solid or ribbed bottom portion is connected between the bottom most portions of the opposing and parallel interior sidewalls.
In a third embodiment of the invention, the bottom portion of the immediately above-described second embodiment of the invention is cut in half along its central longitudinal axis, and strips of Velcro® pads are placed at various positions on the top of one of the bottom portions, and at like various positions on the bottom of the other half portion, for permitting the two portions to be secured together for providing a desired distance between the two interior side portions for accommodating different sizes of cylindrical tanks.
Various embodiments of the present invention are described in detail below with reference to the drawings, in which like items are identified by the same reference designation, wherein:
In a first embodiment of the invention, as shown in
With further reference to
The carrier or cylindrical tank holder 2 permits a user to transport cylindrical tanks, such as propane tanks 22, safely and securely in the trunk of an automobile, for example, or in the flatbed of a truck. Velcro® or other types of known fasteners on the bottom of bottom segments 12 and 18 can be used for preventing the carrier 2 from sliding about during the transport of a cylindrical tank as described. Typically, if the carrier 2 is placed into an automobile trunk that is carpeted, and the propane or other cylindrical tank being transported is heavy, there will be little tendency for the carrier or holder 2 to slide. Also, when not used, the carrier 2 can readily be hung up on a garage wall, or otherwise conveniently stored.
A second embodiment of the invention is shown in the front pictorial view thereof of
With reference to
Although various embodiments of the invention have been shown and described above, they are not meant to be limiting. Those of skill in the art may recognize certain modifications to these embodiments, which modifications are meant to be covered by the spirit and scope of the appended claims. For example, the carriers of the present invention, as shown and illustrated can be used to safely transport cylindrical tanks in other than the trunks of cars or beds of pickup trucks, but can also be used on the front or rear seats of the vehicles, back portion of SUV's, and so forth, in which case safety belts may also be useful in forcing the sides of the tank being transported tightly against the sloping interior sidewall portions of the carrier in one of its illustrated embodiments. However, tests made by the inventor have shown that there is no need for the use of ropes or straps to more rigidly secure a cylindrical tank within one of the carriers of the present invention. Regardless, Velcro® straps, nuts and bolts, or other known securement means for providing a temporary mount of the carrier in the bed of a pickup truck, or trunk of an automobile, for example, can also be employed for use. Also, the cylindrical tank carriers of the various embodiments of the invention can be extended lengthwise or expanded for providing for the safe transport for a plurality of cylindrical tanks, such as propane tanks, and also can be utilized singularly or in multiple units for safely storing cylindrical tanks when not in transport in use.
