Description

BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWINGS

[0012] The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:

[0013] FIG. 1 is an isometric perspective view of a prior art vehicle cab access assembly.

[0014] FIG. 2 is an isometric perspective view of according to an embodiment of the disclosure.

[0015] FIG. 3 is a detail view of an embodiment of the disclosure.

[0016] FIG. 4 is a side view of an embodiment of the disclosure.

DETAILED DESCRIPTION OF THE INVENTION

[0017] With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new access assembly embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

[0018] As best illustrated in FIGS. 1 through 4, the vehicle cab access assembly 10 generally comprises a step fairing 12, which is configured to be mountable to a respective side 14 of a vehicle 16 so that the step fairing 12 is positioned below a door 18 positioned in a cab 20 of the vehicle 16. The step fairing 12 comprises three steps 22 and is configured to facilitate egress and ingress to the cab 20 of the vehicle 16. Prior art access assemblies generally comprise two steps 22, as shown in FIG. 1, which are difficult to ascend and descend, particularly for older drivers or drivers who are physically impaired, such as drivers suffering from arthritis. In contrast, the step fairing 12, once installed, provides three steps 22, as shown in FIG. 2, and is easier to ascend and descend.

[0019] Each step 22 comprises a pair of side panels 24, a tread rung 26, and a riser 28. The tread rungs 26 are grated, as shown in FIG. 2, or slotted (not shown) and thus are configured to be slip resistant and to prevent of accumulation of foreign materials. The side panels 24 and the risers 28 comprise metal or plastic. The tread rungs 26 comprise metal.

[0020] The step fairing 12 is configured so that, upon mounting of the step fairing 12 to the respective side 14 of the vehicle 16, a bottommost tread rung 30 is positioned no more than 609 millimeters above a surface upon which the vehicle 16 is positioned. Each tread rung 26 has a depth 32 of at least 12.7 centimeters. The depths 32 of the tread rungs 26 may be substantially equivalent, although the present invention also anticipates the depths 32 of the tread rungs 26 being nonequivalent. Each tread rung 26 has a width 34 of at least 25.4 centimeters. The widths 34 of the tread rungs 26 may be substantially equivalent, although the present invention also anticipates the widths 34 of the tread rungs 26 being nonequivalent.

[0021] The risers 28 are substantially height equivalent. Each step 22 is configured to withstand a vertical static load of at least 204 kilograms. The step fairing 12 is configured to be mountable to a respective side 14 of a cab over engine (COE) vehicle 36. For example, the step fairing 12 is configured to be mountable to a driver side 38 of a COE vehicle 36, as shown in FIG. 3, or to passenger side 40 of the COE vehicle 36 (not shown).

[0022] In use, step fairing 12 is mounted to a driver side 38 of a cab over engine vehicle 36 so that it is positioned beneath the door 18. The driver then can utilize the three steps 22 to enter and to exit the cab 20.

[0023] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

[0024] Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
