Abstract
Abstract A modular deck construction characterized by having one or more prefabricated floor panels with prefabricated stair parts, i.e., treads and side runners, together with prefabricated banisters and side railing members. The deck frame and other parts are pre-drilled as necessary to provide a fail-safe arrangement for mounting the stairs, banisters, and side rails with the floor panel such that the stair may be positioned on either side or either end of the floor deck. The modular system facilitates assembling a deck of any number of the prefabricated floor panels. The invention also includes connecting means for joining interior corners of adjacent floor panels and supporting them in an elevated position above ground level.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
A modular deck system comprising: (a) a rectangular floor member having a perimeter support frame consisting of end and side members joined together at their adjacent ends and adapted to receive a floor, said side members being twice as long as said end members; (b) a plurality of railing sections each as long as one of said end members and having a pair of laterally spaced vertical support members adapted to be secured to the end and/or the side members of said perimeter support frame, in a pre-determined position; (c) a pair of upper and lower laterally spaced vertical support members for supporting stair runners and stair treads attached thereto; (d) knee means on said vertical support members adapted to engage the lower side of said perimeter support members for supporting said support frame and said floor; and (e) means for positioning said vertical support member at either end of the rectangular floor member or in either of two pre-determined positions on either side of said rectangular floor member.
Claim 2
Dependent Claim
169 words
A modular deck system comprising: (a) a rectangular floor member having a perimeter support frame consisting of end and side members joined together at their adjacent ends and adapted to receive a floor, said side members being twice as long as said end members; (b) a plurality of railing sections each as long as one of said end members and having a pair of laterally spaced vertical support members adapted to be secured to the end and/or the side members of said perimeter support frame, in a pre-determined position; (c) a pair of upper and lower laterally spaced vertical support members for supporting stair runners and stair treads attached thereto; (d) knee means on said vertical support members adapted to engage the lower side of said perimeter support members for supporting said support frame and said floor; and (e) means for positioning said vertical support member at either end of the rectangular floor member or in either of two pre-determined positions on either side of said rectangular floor member.
Claim 3
Dependent Claim
93 words
The invention of claim 1 wherein said means for positioning said vertical support members comprise: pre-drilled laterally spaced holes in said end member and two pair of laterally spaced holes in said side members and side perimeter members for receiving connecting means to connect said pair of laterally spaced vertical rail support members or said pair of upper laterally spaced vertical stair runner support members to said perimeter frame at either end of said rectangular floor or at either of two positions on each of the two sides of such rectangular floor member.
Claim 4
Dependent Claim
61 words
The invention of claim 2 wherein said pre-drilled laterally spaced holes in said end and side perimeter members comprise a single hole near one end of said lateral space and a pair of vertically disposed holes near the other end of said lateral space and said lateral space is approximately the same as the length of one of said end members.
Claim 5
Dependent Claim
87 words
The invention of claim 2 wherein said laterally spaced pre-drilled holes include a single pre-drilled hole in one of said laterally spaced vertically rail support members and a pair of vertically disposed pre-drilled holes in the other of said laterally spaced vertical rail support members, said single hole said pair of vertically disposed holes adapted to be registered with said single hole and said pair of vertically disposed holes in said end or said side support member when said vertically spaced rail support members are connected thereto.
Claim 6
Dependent Claim
109 words
The invention of claim 2 including a single, pre-drilled hole in one of said upper laterally spaced vertical support members for supporting said stair runners and a vertically disposed pair of pre-drilled holes in the other of said upper laterally spaced vertical support member for supporting said stair runners, said single hole and said vertically disposed pair of holes adapted to be registered with said single hole in said pair of vertically disposed holes in said end or said side support members when said upper laterally spaced vertical support members for supporting said stair runners are connected to said end and said side members of said perimeter support frame.
Claim 7
Dependent Claim
26 words
The invention of claim 1 including linking means secured to adjacent sides of said vertical support members secured adjacent a corner of said perimeter support frame.
