The present invention relates to an engagement device for mechanical gearbox (10; 10') comprising an actuating means, suitable to drive the rotation of a drive shaft (11) around a rotation axis (R) to couple a first gear (1) to a second gear, a first lever (17) rotating independently of said drive shaft (11), and a second lever (19; 19') integral with said drive shaft (11), both said levers being actuated by said actuating means (13), and an elastic link (21), interposed between said first and second levers in such a way that said levers can rotate by different angles when actuated by said actuating means (13). Thanks to the interaction between said levers (17, 19; 17, 19') and said elastic link (21) it is possible to couple the first gear (1) to the second gear, even when said gears are not aligned with each other and the teeth of said gears interfere with each other, simply by actuating the rotation of at least one of said gears.

A process of applying a coating to a substrate is provided. A layer of a ceramic material is applied on the substrate by a thermal spray process. The layer is then subject to plasma electrolytic oxidation (PEO) processing to densify the layer such that a porosity of the layer after PEO processing is lower than a porosity of the layer before PEO processing, or modify the layer by incorporating additional ceramic phases from the electrolyte bath into the densified layer, or improve the adhesion of the thermal spray layer. A base layer may be applied to the substrate with PEO processing before the above referenced layer is applied and/or a ceramic topcoat may be applied to the above referenced layer by a thermal spray process.

The present invention relates to a sports boot (1; 1'), of the type comprising a shell (3; 3') and a cuff (5; 5') both made of a substantially rigid plastic material, and having a tightening system (10) for tightening said shell and said cuff onto the user's foot and ankle, or releasing said shell and said cuff from the user's foot and ankle. According to the invention, said tightening system (10) comprises one or more traction cables (11; 11a, 11b), first guide elements (13) arranged at the shell, second guide elements (15) arranged at the cuff, and a single tensioning mechanism (17) suitable to control the tensioning or releasing of said one or more traction cables. Thanks to the provision of a single tensioning mechanism, the user can advantageously act on a single actuating device to simultaneously tighten or release both the shell and the cuff of the boot according to the invention.

A modular electrical connection system (100) for two/three-dimensional lighting is described, comprising a plurality of two-dimensional modules (10), each module (10) comprising two distinct polarities (11, 12) connectable to an electrical supply, a negative pole (11) and a positive pole (12), each pole (11, 12) being formed by a bar of electrically conductive material connected to a light source (50) by means of an elastic element (40), each pole (11, 12) connected to a structural element (21, 22) formed by a bar of electrically conductive material by means of an elastic element (40).
