Abstract A miter corner construction for multiple-panelled enclosures, such as aquarium tanks, comprising a frame corner formed of three mutually perpendicular members and a three-branched connector clip positioned within the corner. Each frame member comprises two longitudinal walls in right-angled relation, each of the walls having a longitudinal rib, the pair of ribs forming therebetween a cavity within which is disposed one of the clip branches. The lateral edge of each clip branch is notched, a portion of the rib extending into the adjacent notched portion, other portions of the rib being in overlying engagement with the clip branch, whereby the three frame members are held against longitudinal and transverse movement relative to each other and the clip. In the method of making the construction, the miter end portions of the three frame members are first slipped over the respective branches of the clip until the members are in mated engagement. Then, by a single swedging action, portions of the ribs are swedged into adjacent notched portions of the respective clip branches, and at the same time other selected portions of the ribs are swedged into overlapping engagement with the respective adjacent clip branches.
A miter corner construction having three frame members and a three-branched coacting connector clip therein, said frame members being in mutual right angular relation and operatively mated at adjacent miter ends, each of said frame members having two spaced parallel longitudinally extending ribs, each of the three branches of said clip being positioned between the pair of ribs of the corresponding frame member, the lateral edges of said branches having notched portions therein, said ribs having sections thereof extending into said respective notched portions of adjacent branches and other sections in overlying engagement with the respective adjacent branches, whereby the frame members and the connector clip are held locked against movement relative to each other both longitudinally and transversely normal to their respective planes, each frame member having two lateral longitudinally extending walls in right-angled relation, each of said walls having thereon one of said ribs, each of said branches having two lateral longitudinally extending walls in right-angled relation and in engagement with corresponding ones of said frame member''s walls, said branches each having a bottom surface between said longitudinally extending walls which is in engagement with the corresponding one of said frame members between the ribs thereof, the lateral edges of said branches'' walls having therein the said respective notched portions.

A miter corner construction having three frame members and a three-branched coacting connector clip therein, said frame members being in mutual right angular relation and operatively mated at adjacent miter ends, each of said frame members having two spaced parallel longitudinally extending ribs, each of the three branches of said clip being positioned between the pair of ribs of the corresponding frame member, the lateral edges of said branches having notched portions therein, said ribs having sections thereof extending into said respective notched portions of adjacent branches and other sections in overlying engagement with the respective adjacent branches, whereby the frame members and the connector clip are held locked against movement relative to each other both longitudinally and transversely normal to their respective planes, each frame member having two lateral longitudinally extending walls in right-angled relation, each of said walls having thereon one of said ribs, each of said branches having two lateral longitudinally extending walls in right-angled relation and in engagement with corresponding ones of said frame member''s walls, said branches each having a bottom surface between said longitudinally extending walls which is in engagement with the corresponding one of said frame members between the ribs thereof, the lateral edges of said branches'' walls having therein the said respective notched portions.
Claim 3
Dependent Claim
29 words
A miter corner construction according to claim 1, the said rib sections being swedged transversely inwardly into said respective notched portions and in overlying relation to said respective branches.
Claim 4
Dependent Claim
56 words
A miter corner construction according to claim 2, the pair of ribs of each of said frame members defining therebetween a longitudinal cavity, said branches being disposed within said respective cavities, the height of said ribs other than said swedged sections thereof being greater than the thickness of the adjacent clip branches and thereby extending thereabove.
