Description

BACKGROUND OF THE INVENTION

The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.

1. Field of the Invention

The present invention relates generally to the field of platform dolly and more specifically relates to an adjustable platform dolly over all-terrain.

2. Description of Related Art

Most adjustable platform dollies cannot handle rough terrain efficiently. Most platform dollies do not expand to handle different sized loads and are not multi-functional. Additionally, dollies do not keep direction and are apt to go in any direction. Furthermore, dollies are difficult to load and often the load will fall off. A suitable solution is desired.

U.S. Pat. No. 4,166,638 to Alfred De Prado relates to an adjustable dolly. The described adjustable dolly includes a wheeled platform base of adjustable length, fitted with straps for securing a load to the base, with projecting handles mounted to an end wall of the base and with shoulder padding fixed under the base end to enable a household mover to life and support an end of the carriage on his shoulder for the moving of items of furniture placed on the base.

U.S. Pat. No. 5,599,031 to Douglas Hodges relates to a work dolly having adjustable height, width and length. The work dolly having adjustable height, width and length includes a dolly for movably supporting a load having an adjustable frame with side members and end members. Each side member and end member consists of slidable sections in telescoping relationship for adjusting length and width of the frame. A wheeled support is carried on the underside of the frame for transport purposes.

BRIEF SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known platform dolly art, the present disclosure provides a novel adjustable all-terrain dolly system. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide an adjustable all-terrain dolly system.

An adjustable all-terrain dolly system is disclosed herein, in a preferred embodiment, comprising: a chassis assembly that includes a frame which has a right-side rail, a left-side rail, a first-adjustable cross member and a second-adjustable cross member, and a first-rolling assembly to include a first-set of inline wheels and second-rolling assembly to include a second-set of inline wheels and at least one adjustable-locking mechanism.

The chassis assembly may comprise in functional combination: the frame, the first-rolling assembly, the second-rolling assembly, and at least one adjustable-locking mechanism. The frame is structurally defined by a right-side rail, a left-side rail, a first-adjustable cross member, and a second-adjustable cross member. The frame may comprise a platform.

The right-side rail is perpendicular to first-adjustable cross member and left-side rail is perpendicular to second-adjustable cross member. The first-rolling assembly is structurally connected to the right-side rail and the second-rolling assembly is structurally connected to the right-side rail, respectively. The right-side rail is parallel to the left-side rail and the first-adjustable cross member is parallel to the second-adjustable cross member. At least one adjustable-locking mechanism is joined to a first-proximal end of said first-adjustable cross member. At least one adjustable-locking mechanism is joined to a second-proximal end of said second-adjustable cross member. The adjustable all-terrain dolly system is configured to transport a load over a surface.

The first-rolling assembly and the second-rolling assembly are linearly aligned and modular. The first-rolling assembly and said second-rolling assembly each may comprise at least two wheels in linear orientation. The at least two wheels in linear orientation are coupled to at least one track. At least one track each may comprise a wheel-skirt. In a preferred embodiment, first-rolling assembly and said second-rolling assembly each may comprise exactly four wheels in a linear orientation (on each side). The four wheels in linear orientation maintain a common plane during use relative to each other.

The first-adjustable cross member and second-adjustable cross member are telescopically extendable and retractable. The right-side rail is adjustable to the left-side rail to a maximum of forty two inches via moving the first-adjustable cross member and the second-adjustable cross member in relation to each other.

At least one adjustable-locking mechanism may comprise a rotatable fastener. The rotatable fastener may comprise at least one wing by which to manipulate the rotatable fastener in relation to the first-adjustable cross member and the second-adjustable cross member. The adjustable all-terrain dolly system is configured to transport a load over a surface. The adjustable all-terrain dolly system is arranged as a kit.

The present invention holds significant improvements and serves as an adjustable all-terrain dolly system. Preferably, an adjustable all-terrain dolly system should provide efficient means for transporting items over difficult terrains and, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable adjustable all-terrain dolly to avoid the above-mentioned problems.

For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.
