Definitions

• the present invention relates to a joining and levelling system for parts of furniture and furnishing items with minimum encumbrance.
• Solutions are also known in which the joining and levelling systems for parts of furniture and furnishing items are contained in confined spaces below the furniture and propose a generally front actuation that involves both the device for joining a bottom to a shoulder and also the levelling device of the piece of furniture .

• the hollow pusher element 52 is positioned coaxially with respect to the outside of the casing 44, 45.
• the rotation of the threaded screw 49 causes the upward and/or downward movement of the hollow pusher element 52 and the adjustment of the leveller by means of a thrust engagement inside a blind hole 43 formed in the bottom 12.
• a tool controls, through its tip, the pinion 47 passing through both a front opening 64 of the body 16 and the hole 46 of the half-shell 44 of the casing .
