Abstract
Attachment holes are formed in a first piece of furniture, and a dowel hole is formed in a second piece of furniture. A hinge unit includes a hinge arm having attached thereto a mounting plate, a cup-shaped dowel dimensioned to fit within the dowel hole, and a pair of toggle joints connecting the hinge arm and the cup-shaped dowel to form a quadrangular hinge linkage, with the mounting plate having extending therefrom rods dimensioned to fit in the attachment holes. First pins having first hook members are permanently mounted within and rotatably extended through the mounting plate at positions eccentric to the longitudinal axes of the rods. Second pins having second hook members are permanently mounted within and rotatably extended through the cup-shaped dowel at positions adjacent the edge thereof. The hinge unit is positioned in the closed position thereof, and the rods of the mounting plate are inserted into the attachment holes of the first piece of furniture. The first pins are then rotated such that the first hook members are moved outwardly of the rods and are driven into and embedded in the lateral wall surfaces of the attachment holes. The second piece of furniture is then moved in a direction substantially at a right angle to the first piece of furniture until the cup-shaped dowel is inserted into the dowel hole. The second pins are then rotated such that the second hook members are moved outwardly of the cup-shaped dowel and are driven into and embedded in the lateral wall surface of the dowel hole.
