SINGLE LEVER MIXER

Claims

1. Single lever mixer (1), comprising: a tubular body (2) with a substantially vertical axis; a cup (10) placed in a tubular body (2) and having two inlet openings (12), for hot water and for cold water, as well as one outlet opening for mixed water, which communicate with a spout (7); a mixing cartridge (20) located in the cup (10) and having two inlet openings (28), for hot water and for cold water, as well as one outlet opening (29) for mixed water, which communicate with the corresponding inlet openings (12) and outlet opening (13) made in the cup (10); a lever (22) projecting upward from the cartridge (20) and capable of being set in a rocking and rotating motion by means of a handle (25) for releasing / closing the flow and mixing, respectively, wherein said handle (25) is a continuation of said tubular body (2); characterized in that the said handle (25) comprises a lower body (30) and an upper body (40) connected to each other along opposite inclined surfaces so that they are capable of rotating together and there is the possibility of linear sliding of the upper body (40) of the handle relative to the lower body (30) of the handle from top to bottom and vice versa, along the said inclined surfaces.

2. The mixer according to claim 1, characterized in that the lower body (30) of the handle has an internal cavity (32) for the passage of said lever (22), and the protruding end of the lever is connected to the upper body (40) of the handle.

3. The mixer according to claim 2, characterized in that from the upper inclined surface of the lower body (30) of the handle a pair of ribs (36) protrudes, limiting the said internal cavity (32) and defining on the outside a pair of linear guides (37) for sliding engagement of corresponding guides (49) present on the sides of the groove (48) formed in the lower inclined surface of the upper body (40) of the handle, suitable for accommodating the said ribs (36), so that the upper body (40) of the handle remains limited by the lower body (30) of the handle with the possibility of sliding between the said inclined surfaces.

4. A mixer according to claim 2 or 3, characterized in that said upper body (40) of the handle is made of two mirror components (41) having opposite flat contact surfaces, on each of which a guide (46) is formed, adapted to receive with the possibility of sliding the corresponding end of the pin (60), which passes through the opening (26) at the end of the lever (22) of the cartridge (20), to limit said lever by the movement of the upper body (40) of the handle.

5. The mixer according to claim 4, characterized in that around the said guides (46) for the pin (60) there are corresponding bas-relief templates (47), accommodating the thickness of the lever (22) and allowing the lever to perform a rocking movement around its axis (27) when the handle is actuated to release and shut off the flow of water.

6. A mixer according to any one of paragraphs 3-5, characterized in that a cover (50) is placed on the lower body (30) of the handle, which repeats the shape of the lower body, and the cover has an inclined upper surface (51), along which the upper body (40) of the handle slides, and on the said inclined surface (41) there is an opening (52) for the passage of the said ribs (36).

7. The mixer according to claim 6, characterized in that on the inner side of the side wall of the cover (50) there is at least one projection (53) designed for installation in a vertical groove (38) present in the lower body (30) of the handle, to limit the rotation of the cover (50).

8. A mixer according to any one of paragraphs 4-7, characterized in that a leveling cap (70) is installed on the upper body (40) of the handle, on the inner side of the bottom wall of which there is a profiled rib (71) that engages with the corresponding grooves (62) present on the upper surface of the two components (41).

9. The mixer according to item 8, characterized in that an aesthetic cover (80) is installed on said cap (70).

10. A mixer according to any one of paragraphs 6-9, characterized in that at the lower end of the said components (41) of the upper body (40) of the handle there is an anti-friction ring (61), which ensures smooth sliding along the said cover (50).
