Interpatent S.R.L.

The present invention relates to a line trimmer head (1) for brush cutters which allows preventing accidental disengagement of its components during use. The trimmer head (1) comprises a first shell (3) and a second shell (5), which can be removably coupled to each other by means of a snap-fit connection. To this purpose, said second shell (5) comprises one or more elastic tabs carrying respective fitting elements (25) and said first shell comprises corresponding fitting seats (37, 29) in which said fitting elements engage. According to the invention, said elastic tabs are provided with inwardly facing protuberances (31) protruding inside the inner volume of the casing of the trimmer head (1), and a stop element (7b) is arranged inside said inner volume, which stop element, in normal conditions of use, is axially aligned to said protuberances so as to prevent accidental movement of the elastic tabs (5b) and the respective fitting elements (25) that could cause disengagement of the second shell (5) from the first shell (3).

The present invention relates to a sliding assembly (100) for a sliding device for a vehicle seat which comprises at least one anchoring mechanism (20), movable between an operative position, in which it is adapted to engage with the possibility of sliding a lower rail of a sliding device, and an inoperative position, in which it is adapted to be disengaged from said lower rail. The anchoring mechanism is brought from the operative position to the inoperative position by a combined movement including a translational movement component along a direction substantially perpendicular to the vehicle floor and a rotational movement component around an axis substantially parallel to the vehicle floor and oriented along the longitudinal direction. The sliding assembly (100) further comprises a locking element (10) for selectively engaging without possibility of sliding said lower rail. In a preferred embodiment, the sliding assembly further comprises a play recovery element (50) that allows compensation for any play between the sliding assembly and said lower rail in the three Cartesian directions.

The present invention relates to a gearbox (30; 40) with gears comprising a driving wheel (4) and a driven wheel (3) facing each other, which are arranged on a common rotation axis and are provided, on their respective facing surfaces (21, 22), with crown gears (5A, 5B) arranged on different diameters of said wheels (4, 3). Said surfaces are conical, so as to be inclined by an inclination angle (α) relative to the respective rotation axis of said wheels (4, 3), and said gearbox (30; 40) further comprises a rod (9), which extends along a longitudinal axis (19) arranged transversely to the rotation axis of said wheels (4, 3) and carries a gear system comprising first gears (7A') designed to mesh with crown gears (5A) of the driving wheel (4) and second gears (7B') designed to mesh with crown gears (5B) of the driven wheel (3).

A union (30) of mating ends of tubes or pipes is provided. The union (30) includes a female fitting (32) forming a free end of a tube or pipe and having an inner facing radiused surface and an integral outward extending ferrule (54), a male fitting (38) having an outer facing radiused surface for sliding engagement with the inner facing radiused surface of the female fitting (32), and a seal (34) located between the inner facing radiused surface of the female fitting (32) and the outer facing radiused surface of the male fitting (38). The union (30) further includes a compression collar (36) having an integral ferrule (56) for being compressed against the ferrule (54) of the female fitting (32) and an inner facing radiused surface for engagement with the male fitting (38) for capturing the male fitting in an engaged condition with the female fitting.

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.

A filtering device (1) for purifying the air present in an ophthalmic lens processing environment comprising a flow distribution head (2) provided with an outlet fitting (3) and an inlet fitting (4) suitable to communicate directly or indirectly with a usage tank in free contact with an ophthalmic lens processing environment, arranged in a lower room beneath a work bench accessible to an operator, so that the usage tank is underneath a grinding machine for processing ophthalmic lenses and collects by gravity a processing and cooling liquid which conveys with it the impurities produced by the processing of the ophthalmic lenses by the grinding machine, an outer container (5) coupled to the distribution head (2) and having an inner volume (6) communicating with the inlet fitting (4), air purification means (7) arranged in the inner volume (6) of the outer container (5) and communicating with the inlet fitting (4), air filtering means (8), communicating with the outlet fitting (3) and arranged inside the outer container (5) and cooperating with the purification means (7) in such a way as to receive from the purification means (7) the air coming from the inlet fitting (4) and yet purified by the purification means (7), and ventilation means (9) operatively connected to the filtering means (8) and suitable to direct the purified air outside the flow distribution head (2) through the outlet fitting (3).

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.
