Claim 1
Independent Claim
138 words
A panel assembly comprising: a pair of substantially congruent and rectangular flat panels each having a plurality of straight edges meeting at corners; respective W-section rails extending along the edges and having squared ends at the corners, each rail forming a pair of parallel, spaced, and inwardly open rail grooves receiving the respective edges and holding the panels parallel to and spaced from each other, and a central outwardly open hardware groove flanked by the rail grooves and opening oppositely thereto; and respective corner pieces at the corners each having a pair of projections fitting longitudinally into the ends of the central grooves of the respective rails of the same panel assembly and securing same together against relative movement, each corner piece being formed with at least one outwardly open threaded bore adapted to receive a threaded stem.
Claim 2
Dependent Claim
138 words
A panel assembly comprising: a pair of substantially congruent and rectangular flat panels each having a plurality of straight edges meeting at corners; respective W-section rails extending along the edges and having squared ends at the corners, each rail forming a pair of parallel, spaced, and inwardly open rail grooves receiving the respective edges and holding the panels parallel to and spaced from each other, and a central outwardly open hardware groove flanked by the rail grooves and opening oppositely thereto; and respective corner pieces at the corners each having a pair of projections fitting longitudinally into the ends of the central grooves of the respective rails of the same panel assembly and securing same together against relative movement, each corner piece being formed with at least one outwardly open threaded bore adapted to receive a threaded stem.
Claim 3
Dependent Claim
56 words
The panel assembly defined in claim 1 wherein the panels are vertical with lower corners and upper corners, bores of the pieces of the upper corners opening upward and the bores of the pieces of the lower corners opening downward, the assembly further comprising: guide assemblies having bolts engaged in the bores of the lower corners.
Claim 4
Dependent Claim
68 words
The panel assembly defined in claim 1 wherein the panels are vertical with lower corners and upper corners, bores of the pieces of the upper corners opening upward and the bores of the pieces of the lower corners opening downward, the assembly further comprising: guide assemblies having bolts threaded into the bores of the lower corners and hangers having bolts threaded into the bores of the upper corners.
Claim 5
Dependent Claim
76 words
The panel assembly defined in claim 1, further comprising: a clip engageable laterally into a central groove of a first such panel assembly and simultaneously longitudinally over a corner piece of a second such panel assembly extending perpendicularly from the first assembly; and means for securing the clip to the corner piece of the second panel assembly and thereby fixing the first and second panels together with the second assembly projecting perpendicularly from the first assembly.
Claim 6
Dependent Claim
20 words
The panel assembly defined in claim 1, further comprising bolts forming pivots received in at least some of the bores.
Claim 7
Dependent Claim
20 words
The panel assembly defined in claim 1 wherein the projections are arms fitting generally complementarily into the respective central grooves.
Claim 8
Dependent Claim
31 words
The panel assembly defined in claim 6 wherein the central grooves are undercut such that the arms can only be inserted longitudinally of the respective rails therein or removed longitudinally therefrom.
Claim 9
Dependent Claim
34 words
The panel assembly defined in claim 6 wherein each central groove is formed with an aperture adjacent the respective rail end, each arm being formed with a tooth engaging laterally through the respective aperture.
Claim 10
Dependent Claim
14 words
The panel assembly defined in claim 8 wherein the teeth are of sawtooth shape.
Claim 11
Dependent Claim
25 words
The panel assembly defined in claim 1 wherein the corner pieces are formed adjacent the projections with recesses into which the respective rail ends engage.
Claim 12
Dependent Claim
25 words
The panel assembly defined in claim 1, further comprising means including formations on the projections and rails for releasably securing same together against relative movement.
