Patent attributes
The present invention is an anchoring biscuit device for joining three boards. It includes, (a) an at least partially flat horizontal top element having an imaginary center line, having opposite side walls, and having a top view footprint adapted to be inserted into grooves of adjacent boards; (b) at least one substantially vertical support member attached to the underside of the top element and extending downwardly therefrom for a predetermined length for joinder of two adjacent boards which contain said grooves for receiving portions of said top into said grooves; and, (c) at least one compressive element located on aid device, with at least a portion of said at least one compressive element, from a top view footprint, being located away from said imaginary center line and way from said vertical support member, wherein said compressive element is adapted to at least partially collapse under predetermined compressive force.
