Corner construction for aquarium or the like

Claim 2

A corner assembly including three elongated frame members, comprising: two of said frame members having abutting mitered ends, formed to receive a key; said key presenting an arm for engagement within spaced, generally parallel portions of an abutting end of each of said two frame members; said key being formed to cooperate with portions of said abutting ends to define an angular cavity, opening generally transversely of the longitudinal extension of said two of said elongated frame members; said last mentioned cavity being operable to receive an abutting end of the third of said three elongated frame members; and said key being formed to cooperate with said abutting ends of said three frame members to frictionally, simultaneously engage all three of said elongated frame members, whereby said three elongated frame members are held firmly together.

Claim 3

A corner assembly, as defined in claim 1, wherein: said key presents arms extending longitudinally of at least two of said members, the arms of said key being of an undulating configuration so as to present a series of recesses and crests; and at least one of said three elongated frame members being at least partially formed with a surface corresponding with that of the key to frictionally engage therewith, to seCure said frame member and key together.

Claim 4

A corner assembly, as defined in claim 1, wherein: each of said frame members consists of a strip of extruded material having an angular cross section.

Claim 5

A corner assembly, as defined in claim 1, wherein: said key presents three arms extending at angles to each other.

Claim 6

A corner assembly, according to claim 3, wherein: each of said frame members is formed with at least one flange; each said flange being inclined inwardly when the corner assembly is properly constructed with pairs of said flanges in overlapping end relationship; and the end of one flange, of each pair of said flanges, being bevel cut to form said overlapping end relationship.

Claim 7

A structure having bottom and side walls, in the form of panels: at least a portion of said side walls being formed of transparent material; said bottom and side walls being secured together by frame members extending along the adjacent edges of said bottom and side walls; each of said frame members comprising side portions disposed at right angles with respect to each other; at least one of said side portions being provided with a panel supporting web projecting inwardly and extending generally parallel with respect to the other of said sides; said panel supporting web cooperating with at least one of said panels to define a substantially enclosed main, sealant cavity; an excess sealant receiving cavity being disposed immediately adjacent said main sealant cavity; and said excess sealant cavity being substantially enclosed and partitioned from said main sealant cavity by at least one of said panel supporting webs.

Claim 8

A structure having bottom and side walls, in the form of panels: at least a portion of said side walls being formed of transparent material; said bottom and side walls being secured together by frame members extending along the adjacent edges of said bottom and side walls; each of said frame members comprising side portions disposed at right angles with respect to each other; at least one of said side portions being provided with a panel supporting web projecting inwardly and extending generally parallel with respect to the other of said sides; said panel supporting web cooperating with at least one of said panels to define a substantially enclosed main, sealant cavity; an excess sealant receiving cavity being disposed immediately adjacent said main sealant cavity; and said excess sealant cavity being substantially enclosed and partitioned from said main sealant cavity by at least one of said panel supporting webs.

Claim 9

A construction according to claim 6, wherein: said substantially enclosed excess sealant cavity is at least partially defined by one of said panels.
