Abstract
Abstract A modular building panel having an interlock mechanism for connecting building panels in series is disclosed, includes two metal sheets separated by an insulating foam core bonded to the sheets and a first interlocking member on one side and a second interlocking member on the other side. The male connector configuration as well as the female connector configuration in this invention are both formed of curvilinear surfaces. The male connector as well as the female connector extends outwardly from the side faces of the foam so that the foam is protected from damage. The male connector is formed by bending the metal edge almost back upon itself. The female connector includes a V-shaped valley to ultimately receive the male connectors when the male connectors are in a nested position. The male and female connectors provide a double gutter system to improve the prevention of leakage and condensation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
365 words
An insulating building panel wherein side edges of the panel are connectable to a like adjacently positioned second insulated panel to a form a building system, the panel comprising: a central core of insulating material including first and second major, flat surfaces and side faces; first and second relatively thin, substantially flat and oppositely positioned metallic sheets attached to said first and second major surfaces of said central core of insulating material respectively, said flat metallic sheets forming male and female side edge connectors adapted to be respectively joined to female and male side edge connectors of a like adjacently positioned panel to form said building system; said male side edge connectors being formed integrally with said oppositely positioned thin metallic sheets to form mirror image male connectors, each of said male connectors including an internal, generally convex curved surface; said female side edge connectors being formed integrally with said oppositely positioned thin metallic sheets to form mirror image female connectors, said female connectors including an externally facing generally V-shaped valley formed with an internally curled end portion which provides an externally curved connector area and which terminates outwardly spaced from a side edge of said central core; said internal curved surfaces of said male connectors of said panel being capable of sliding over externally curved connector areas of internally curled end portions of female connectors of a like adjacently positioned panel such that said internal curved surfaces of said male connectors are adapted to nest in said V-shaped valleys of female connectors of a like adjacently positioned panel, one of said side faces of a like adjacently positioned panel core being positionable substantially adjacent to a side face of said central core of said panel, said V-shaped valley on an upper female connector adapted to cooperate with an internal, generally curved surface of an upper male connector of a like adjacent panel to form an elongated space which functions as a first gutter system, and said internally curved end portion of a bottom female connector functioning as a second gutter system to avoid or minimize leakage and condensation whenever said panel is used with an adjacent like panel as combination roof and ceiling members.
Claim 2
Dependent Claim
365 words
An insulating building panel wherein side edges of the panel are connectable to a like adjacently positioned second insulated panel to a form a building system, the panel comprising: a central core of insulating material including first and second major, flat surfaces and side faces; first and second relatively thin, substantially flat and oppositely positioned metallic sheets attached to said first and second major surfaces of said central core of insulating material respectively, said flat metallic sheets forming male and female side edge connectors adapted to be respectively joined to female and male side edge connectors of a like adjacently positioned panel to form said building system; said male side edge connectors being formed integrally with said oppositely positioned thin metallic sheets to form mirror image male connectors, each of said male connectors including an internal, generally convex curved surface; said female side edge connectors being formed integrally with said oppositely positioned thin metallic sheets to form mirror image female connectors, said female connectors including an externally facing generally V-shaped valley formed with an internally curled end portion which provides an externally curved connector area and which terminates outwardly spaced from a side edge of said central core; said internal curved surfaces of said male connectors of said panel being capable of sliding over externally curved connector areas of internally curled end portions of female connectors of a like adjacently positioned panel such that said internal curved surfaces of said male connectors are adapted to nest in said V-shaped valleys of female connectors of a like adjacently positioned panel, one of said side faces of a like adjacently positioned panel core being positionable substantially adjacent to a side face of said central core of said panel, said V-shaped valley on an upper female connector adapted to cooperate with an internal, generally curved surface of an upper male connector of a like adjacent panel to form an elongated space which functions as a first gutter system, and said internally curved end portion of a bottom female connector functioning as a second gutter system to avoid or minimize leakage and condensation whenever said panel is used with an adjacent like panel as combination roof and ceiling members.
Claim 3
Dependent Claim
170 words
A building system including at least two panels as set forth in claim 1: said panels being adjacently positioned substantially horizontally to serve as combination roof and ceiling members such that said first or top metallic sheet of each panel serves as a roof and said second or bottom metallic sheet of each panel serves as a ceiling, one of said male connectors extending from said top metallic sheet and the other of said male connectors extending from said bottom metallic sheet of each panel, one of said female connectors extending from said top metallic sheet and the other of said female connectors extending from said bottom metallic sheet of each panel; said panels being joined such that said internally curled end portion of said bottom female connector forming said second gutter system of one panel is spaced from a bottom surface of a joined male connector of another panel to create an insulating air spaced to prevent the formation of condensation on the bottom surface of said another panel.
Claim 4
Dependent Claim
72 words
The structure set forth in claim 1, including: said side faces of said insulating core being generally aligned with said male and female connectors on said panel but being positioned inside of said male and female connectors to avoid damage to said core of said panel, said side faces being located substantially adjacent to an opposing side face of a like adjacent panel when panels are joined to form a building system.
Claim 5
Dependent Claim
74 words
The structure set forth in claim 1, including: said major surfaces of said insulating core, as viewed in cross-section, including substantially V-shaped valleys which are aligned with said V-shaped valleys of said female connectors of said panel such that an elongated V-shaped gap is formed therebetween to allow said female connectors to temporarily deflect inwardly whenever male connectors of a like adjacent panel begin sliding into connection with said female connectors of said panel.
Claim 6
Dependent Claim
48 words
The structure as set forth in claim 3 including: said internally curled end portion of said bottom female connector of said panel being positioned below said core side faces of said panel to receive water flowing down said core side faces and function as the second gutter system.
