Abstract

Mini-wall parapet structures are disclosed. The structures are of one piece sheet metal with four sided, longitudinal members. A cleat extends downwardly from a lower corner of the structure. The cleat may be a single layer of sheet metal or a folded over layer. The cleat engages a coping member at final installation, and provides an additional attachment for the structure. A folded over primary attachment layer extends from the other lower corner of the structure. The attachment layer is of variable width so that different roof surfaces can be accommodated. The cross section of the structure is either square, or rectangular with longer vertical walls. Rectangular structures are used with thicker insulation. A facade extension may be used with rectangular structures. The top wall includes a gravel guard. The hollow void may be further filled with insulation.

Dependent claims

A mini-wall parapet structure comprising:

a. An elongated, generally box shaped in cross section, sheet metal structure;
b. Said elongated, generally box shaped in cross section, sheet metal structure having four walls, two generally horizontal wall members and two generally vertical wall members arranged in a generally perpendicular four sided box shaped fashion;
c. Said generally horizontal wall members comprising a bottom wall member and a top wall member for said elongated, generally box shaped in cross section, sheet metal structure;
d. Said generally vertical wall members comprising a left side wall member and a right side wall member for said elongated, generally box shaped in cross section, sheet metal structure;
e. Said elongated, generally box shaped in cross section, sheet metal structure includes a bottom left hand corner, a bottom right hand corner, a top right hand corner, and a top left hand corner;
f. Said bottom left hand corner of said elongated, generally box shaped in cross section, sheet metal structure extends vertically downward from said bottom left hand corner as a cleat for said mini-wall parapet structure;
g. Said bottom right hand corner extends horizontally from said bottom right hand corner as an attachment member for said elongated, generally box shaped in cross section, sheet metal structure;
h. Said attachment member further comprising a folded over portion which is extended horizontally back on itself to said bottom right hand corner;
i. The top layer of said folded over portion extends upwardly in a vertical direction from said bottom right hand corner to form said right hand wall member;
j. Said right hand wall member extends to said upper right hand corner,
k. Said top wall member extends from said upper right hand corner in a generally horizontal direction,
l. Said top wall member extends to and includes a generally triangular gravel stop portion at said top left hand corner,
m. Said gravel stop portion comprising a generally right triangle portion which extends upwardly from said top member with the hypotenuse of said generally right triangle portion generally facing right, and the top of said hypotenuse forming the upper left hand corner of said elongated, generally box shaped in cross section, sheet metal structure;
n Said left hand wall member extends downwardly from said upper left hand corner to substantially close said elongated, generally box shaped in cross section, sheet metal structure.

A mini-wall parapet structure comprising:

a. A one piece elongated, generally box shaped in cross section, sheet metal member;
said mini-wall parapet structure formed from a single sheet of corrosion resistant material;
b. One lower outside corner further comprising a down directed extension from the bottom of said one piece elongated, generally box shaped in cross section, sheet metal member;
c. A horizontal extension of variable width from the opposite lower corner of said one piece, generally box shaped in cross section, sheet metal member;
d. Said horizontal extension of said one piece elongated, generally box shaped in cross section, sheet metal member is folded over on itself as a double layered attachment layer of variable width formed of a length,
e. Said double layered attachment layer used for securing said mini-wall parapet structure to a roof deck requiring the length,
f. The top layer of said double layered attachment layer extends upwardly at the inside lower corner as the vertical inner wall of sufficient height to accommodate an insulation layer of a thickness said one piece, generally box shaped in cross section, sheet metal member,
g. Said vertical inner wall extends from an upper inside corner of said mini-wall parapet structure in the opposite direction from said double layered attachment layer, as the top member of said one piece, generally box shaped in cross section, sheet metal member;
h. Said top member extends in a downward direction at an upper outside corner as the vertical wall to substantially close said one piece generally box shaped in cross section, sheet metal.
