Visible and adjustable hanging-bracket group for anchoring a wall cupboard to a wall, with perfected fixing means to the shoulder of the wall cupboard

Abstract

A visible and adjustable hanging-bracket group anchoring a cupboard to a wall includes a bearing structure carrying a protruding arm with a hook that hooks onto a support fixed to the wall, a first and a second regulation mechanism of depth and inclination of the protruding arm, a flange extending from the bearing structure for fixing the hanging bracket to a shoulder of the wall cupboard and having one or more holes adapted to receive a respective fastener, the flange further having elements resistant to shear stress protruding toward the shoulder and synergistic with the fasteners to stably position the hanging bracket on the shoulder. Each element resistant to shear stress is arranged in a different position with respect to the one or more holes receiving the respective fastener and is shaped as a bushing or cylindrical plug having a circular section and extending from the flange.
