US Patent 7905757 Connectors for multi-faceted modules

A system of releasable connectors moldable at various angles, comprising a male arch and a female slot. The male arch resembles an inverted V, having a substantially isosceles outline and a central void adjacent to its base. The female slot has two opposing and medially-facing projections midway along the long edges of its mouth. A secure but releasable connection is made when the male arch is inserted into the female slot, causing the projections of the female slot to become seated in the void of the male arch. Both the male arch and the female slot can be molded at a variety of angles. This feature allows them to be incorporated into multiple, differently-inclined regions of the same piece of molded material.
