Abstract
Abstract A modular type building panel for either vertical or horizontal positioning is provided having a hinge element incorporated to facilitate assembly of the panels. The building panels are of a double walled construction having tongue and socket edge configurations adapted to mechanically interlock when placed in assembled relationship with an adjacent panel. The hinge elements comprise a hinge socket and a hinge pin formed with the respective tongue edge portion and the socket edge portion. The hinge socket is disposed adjacent the upper end of the panel as is the hinge pin which permits interfitting of the two elements during the initial stage of panel assembly thereby providing a support pivot facilitating swinging of two panels into assembled relationship. In one embodiment the hinge socket opens at the longitudinal end of the panel for panels designed for vertical walls. In a second embodiment, the hinge socket is an elongated slot having a relatively narrow throat opening at a longitudinal side edge of the tongue-forming marginal edge portion of a panel designed for horizontal positioning.

Claim 10
Dependent Claim
36 words
A modular building panel according to claim 8 wherein said panel is formed with an end portion thereof opposite said hinge pin inclined longitudinally inward from said end portion to a longitudinal edge of said socket.
Claim 11
Dependent Claim
35 words
A modular building panel according to claim 8 wherein said panel is formed with an end portion thereof opposite hinge socket inclined longitudinally inward from said end portion to a longitudinal edge of said tongue.
Claim 12
Dependent Claim
36 words
A modular building panel according to claim 1 wherein said socket and tongue each include a pair of spaced flanges, said hinge pin carried by one of said pair of flanges in transversely extending relationship thereto.
Claim 13
Dependent Claim
33 words
A modular building panel according to claim 1 wherein said hinge pin is carried by said tongue and includes opposite end portions which project a distance outwardly from either side of said tongue.
Claim 14
Dependent Claim
94 words
A modular building panel according to claim 1 wherein said tongue is formed with a longitudinally extending locking groove disposed a predetermined distance inwardly of a longitudinal edge of said tongue and said socket is formed with a longitudinally extending locking bead, said bead and groove relatively positioned to interfit in interlocking relationship as between adjacently disposed assembled panels, said hinge pin and hinge socket disposed in predetermined lateral relationship to said locking groove and bead to remain in assembled relationship when two adjacent panels are assembled with a respective groove and bead interlocked.
Claim 15
Dependent Claim
80 words
A modular building panel according to claim 13 wherein said hinge socket opens longitudinally outward at an end of said panel and is an elongated slot extending laterally with respect to the panel permitting displacement of a hinge pin therein between a first position where a respective bead and groove of adjacently disposed assembled panels are interlocked and a second position where the respective tongue and socket are in interfitting engagement but with bead and groove out of interlocking engagement.
