Abstract
An arrangement for connecting corresponding edge areas of thin-walled bodies together wherein each edge area is provided with bending sections and empty sections alternately disposed to each other with respect to the corresponding bending and empty sections of the other edge area. The bending sections of the other edge area are disposed through the corresponding empty sections of the edge area whereby the bending sections collectively define a common channel through which an elongate connecting member is inserted to secure the bodies together.
Claims1
An improved arrangement for joining adjacent edge areas of thin-walled bodies, wherein the corresponding edge areas are each provided with a plurality of bent sections and a plurality of recesses, with the bent sections and recesses of one edge area being offset with respect to the bent sections and recesses of the corresponding edge area, thereby permitting the bent sections of one edge area to be disposed through the recesses of the corresponding edge area so that the bent sections of both edge areas collectively define a cylindrical channel for receiving an elongate member to secure the bodies together, which arrangement comprises:
- (a) a corner section carried by each edge area and disposed transversely to the plane of its corresponding body to define a free end;
- (b) the plurality of bent sections are carried by the free end of each corner section, with each bent section having a substantially semi-cylindrical depression and separated from an adjacent bent section by a recess;
- (c) the depressions of the bent sections of one corner section alternate with and are adjacent to the depressions of the bent sections of the corresponding corner section;
- (d) when the edge areas are joined to form the cylindrical channel, the joined bodies define an interior joint side and an exterior joint side, wherein;
- i. the cylindrical channel and corner sections are disposed on and visible only from the interior joint side;
- and
- ii. the exterior joint side presents a linear joint line defined by abutting portions of the edge areas;
- and
- (e) elongated means disposed in the cylindrical channel for securing the edge areas together.
