Rotatable stair-deck system

Abstract

A stair-deck system integrates the deck system and stair system. The deck system seamlessly integrates several components, including the top hatch, deck, stair system, and handle link. The handle link establishes a connection between the top hatch and the deck, offering the operator control over the open and close processes. The stair system, situated on the deck, can be deployed as needed. In its fully deployed configuration, the top hatch functions as a roof, and the stair system can be rotated to multiple orientations for enhanced convenience. The stair system integrates a foldable stair, stair platform, and handle posts, forming a comprehensive system mounted on the deck. Following the full deployment of the deck system, the operator can manually unfold the stairs, rotate the entire system to one of three orientations based on the user's preference and convenience and place the handle post.

         12 . The stair and deck system of  claim 11 , further comprising a pin to lock the stair legs in a desired position when in the use state. 
     
     
         13 . The stair and deck system of  claim 8 , further comprising a stair rail post removably attachable to the upper steps. 
     
     
         14 . A stair and deck system comprising:
 a deck platform convertible between a folded state, positioned adjacent a side of a structure, and a use state, positioned to extend outward from the structure;   a stair system rotatably attached to the deck platform, the stair system operable to selectively provide steps from a selected one of multiple sides of the deck platform;   a stair platform rotatably attached to the deck platform;   stair support arms, the stair support arms extending outward from the stair platform to rotatably support the stairs, wherein at least a portion of the steps are disposed directly adjacent the upper surface of the deck platform in the folded state;   deck rail posts positionable into holes in the deck platform;   a top hatch convertible between the folded state, positioned adjacent a side of a structure, and the use state, positioned to extend outward from the structure; and   a handlebar interconnecting the deck platform and the top hatch,   wherein the deck rail posts are operable to extend through holes in the stair platform to fix the rotation of the stair platform relative to the deck platform once a desired stair location is chosen.   
     
     
         15 . The stair and deck system of  claim 14 , wherein the stair platform is disposed below an upper surface of the deck platform. 
     
     
         16 . The stair and deck system of  claim 14 , wherein:
 the stair system includes upper steps and lower steps, the lower steps foldable against the lower steps in the folded state; and   the stair system include a linkage extending linearly between the upper and lower steps to fix the relative positions thereof in the use state.   
     
     
         17 . The stair and deck system of  claim 16 , further comprising a pin to lock the linkage into the use state. 
     
     
         18 . The stair and deck system of  claim 16 , further comprising:
