Abstract

An extraction device for production of infusion drinks, includes an infusion chamber made up of a fixed part (1) and a moving part (2) which opens and closes the infusion chamber, a lever (20), mounted to rotate relative to an axle (A) and drive the moving part (2) in rotation relative to an axle (B), via a sliding pivot joint between the lever (20) and the moving part (2), characterized in that the axle (B) of rotation of the moving part (2) is arranged on an element mounted such as to move relative to the fixed part (1) to bring the moving part (2) closer to or further away from the fixed part (1).

Claims

1. A device for the extraction of a substance to make beverages by infusion, comprising:

an infusion chamber consisting of a fixed part (1) and a moving part (2) that co-act to open and close the infusion chamber, a lever (20) rotatably mounted relative to an axle A and capable of driving the moving part (2) rotatably relative to an axle (B) through an action of a sliding pivot linkage between the lever (20) and the moving part (2),

wherein the axle (B) of moving part (2) is situated on an element (9) translationally assembled relative to the fixed part (1) in order to bring together or move apart the moving part (2) from the fixed part (1), and

wherein the element (9) translationally assembled comprises a longitudinal part (22) oriented according to a direction of the translation and a transversal part on which is located the axle (B) of the moving part (2).

2. The device according to claim 1, further comprising elastic means for pushing the translationally assembled element (9) towards a position in which the moving part (2) is moved away from the fixed part (1).

3. The device according to claim 1, wherein the translationally assembled element (9) has a rod fitted in a guiding-housing (10).

4. The device according to claim 3, wherein the guiding-housing (10) is formed in a rear face of the fixed part (1).

5. The device according to claim 1, wherein the sliding pivot linkage is situated between the axle (B) of the moving part (2) and the axle (A) of the lever (20).

6. The device according to claim 1, wherein the sliding pivot linkage is equipped with an oblong hole (21) formed in the lever (20) which co-acts with a drive axle (C) on which the moving part (2) is rotatably mounted.

7. The device according to claim 1, wherein a rear face of the fixed part (1) has a stop (23) that limits the rotation of the moving part (2).

8. The device according to claim 1, wherein the moving part (2) has at least one receptacle (5) for packages (6) of a substance to be infused and a base of the at least one receptacle (5) has an opening to allow a pusher (14) to pass into a volume of the at least one receptacle (5) to begin an extraction of the package (6) after use.

9. The device according to claim 8, wherein the pusher (14) is formed on the lever (20) so as to pass into the at least one receptacle (5) at an end of the rotation of the moving part (2).

10. The device according to claim 1, wherein the fixed part (1) consists of a body equipped with a head (7) injecting hot water into a package (6) of a substance to be infused, the head (7) moving to open or close a hot water injection circuit and able to apply on or pierce an end-piece (4) formed on the package (6) and an underside of the body being applied on an upper surface of the package (6) around the end-piece (4).

11. The device according to claim 10, wherein the a body is surrounded by a crown (18) being applied elastically on an upper face of a receptacle (5) receiving a package (6) in the moving part (2).

12. The device according to claim 1, wherein the rotational movement of the moving part (2) is between 45°

and 90°

.

13. The device according to claim 1, wherein the the rotational movement of the moving part (2) is greater than 90°

.

14. A machine for making beverages incorporating the device according to claim 1.

15. The device according to claim 2, wherein the translationally assembled element (9) has a rod fitted in a guiding-housing (10).
