| 1. An anchoring biscuit device for joining three boards, which comprises:
(a) an at least partially flat horizontal top element having a 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 said top element along said center line
of said top element and extending downwardly therefrom for a predetermined length to maintain said top element in a predetermined
position during use for joinder of two adjacent boards which contain said grooves for receiving portions of said top into
said grooves; and,
(c) a plurality of hollow cylindrical compressive elements located on said device, with at least a portion of each of said
compressive elements, from a top view footprint, being located away from said center line and away from said vertical support
member, wherein said compressive elements are adapted to at least partially collapse under predetermined compressive force,
and wherein said compressive elements are located on top of said top element.
