Referring initially to FIG. 1, there is shown a perspective view of one embodiment of the present invention, a fully assembled portable deck (100) for use with recreational vehicles. As shown in FIG. 1, the deck (100) is free standing and is aligned adjacent to the steps of the recreational vehicle to allow ingress and egress from the door of the recreational vehicle. The deck (100) further includes a platform portion (120) supported by a rigid assembled base frame structure (110), which is removablely coupled to the upper support frame structure (150). The upper support frame (150) and base frame (110) can be made of steel or another such compatible metal or material.
FIG. 2 illustrates an exploded view of the assembled base frame (110) structure of deck (100). The assembled base frame (110) is defined by a plurality of individually adjustable ground engaging elongated leg members (112) and a plurality of individually adjustable shorter ground engaging leg members (113). As shown, the shorter leg members (113) and elongated leg members (112) are removably interlocked with a plurality of elongated rail members to form lower support frame structure (115). To form the external perimeter frame (116) of the lower support frame structure (115), the leg members (112, 113) are slideably coupled to a subset of the rail members. In the illustrated embodiment, the external perimeter frame (116) is assembled into a polygonal shape with a predefined number of corners. Then, each rail member of the external perimeter frame (116) is securely bolted in place with a removable threaded fastener. To form the internal frame (119) of the lower support structure (115) another subset of the elongated rail members is removably disposed within the external perimeter frame (116). The internal frame (119) dissects the external perimeter frame (116) into a plurality of receiving channels (117). In the illustrated embodiment of the present invention shown in FIG. 2, the external perimeter frame (116) has a rectangular shape and is dissected into two receiving channels (117). As illustrated in FIG. 2A, in alternative embodiments of the present invention, the external perimeter frame (116) can be dissected into four receiving channels (117).
Each ground engaging leg member (112, 113) of deck (100) shown in FIG. 1 is individually adjustable. Referring now to FIG. 3, there is shown an exploded view of the adjustable leg member (140). The adjustable leg member (140) further comprises a slidable rail having an upper portion (144) and a lower portion (145). The upper portion (144) is adapted to telescope onto the lower portion (145). The upper portion (144) is adjusted up or down into a set position such that the lower support frame (115) is held at a height in relation to the ground level. A locking mechanism is used to securely hold the upper portion (144) and the lower portion (145) at a particular height. As illustrated, the locking mechanism further consists of a column of bores located along the midpoint of the longitudinal axis of the leg member (140). As shown in FIG. 3A, to secure the leg member (140) in place at a specific height, a threaded fastener bolt (142) is inserted into the appropriate bore. At the far end of each lower portion (144) is a ground-engaging member (143) to support each leg member.
