Device for extracting a substance for the preparation of a drink
First Claim
1. A beverage dispensing device for extracting a substance for preparing a beverage, comprising:
- first and second support members pivotally connected together at a support pivot axis and comprising an open position for receiving the substance between the support members and a closed position in which the support members cooperatively define an extraction cavity therebetween;
a liquid intake associated with the extraction cavity for feeding a liquid into the cavity for mixing with the substance to form a beverage mixture;
a fluid exit associated with the extraction cavity for extracting the mixture; and
a linkage operatively associated with the support members for moving the members relative to each other between the open and closed positions, the linkage comprising;
an operation lever pivotally connected to the second support member at a lever pivot axis, and a traction arm pivotally connected to the first support member at a traction pivot axis, the traction arm being connected to the operation lever at a connection pivot axis for controlling opening and closing movement of the support members between the open and closed positions upon movement of the operation lever;
wherein the lever is disposed on the same side of the support pivot as the extraction cavity such that both are accessible to a user from the same side.

Abstract
The present invention relates to a device for extracting a substance for the preparation of a drink. This device includes a first, fixed piece and a second piece that is movable relative to the first about an axis of rotation lying at the rear of the two pieces, with the front of each piece providing a cavity for the substance to be extracted. The device also includes a system for closing and opening the two pieces. This system possesses a two-armed closing lever and two traction rods. The two arms of the closing lever are arranged to rotate about a first pivot on each side of the second piece. The traction rods are arranged to rotate about a second pivot on each side of the first piece. The ends of the two arms of the closing lever and the traction rods are fixed by means of a third, movable pivot so as to interact mutually in order to cause the closing and opening of the device.

19. A beverage dispensing device for extracting a substance for preparing a beverage, comprising:
-
first and second members movably associated with each other for moving between a open and closed positions;
a cavity portion cooperating with the first support member to define an extraction cavity therebetween with the support members in the closed position, the cavity being configured for receiving the substance with the support members in the open position;
a spherical joint rotationally connecting the cavity portion to second support member for enabling the cavity portion to rotate for receiving the substance and aligning against the other of the support members in the closed position;
a liquid intake associated with the extraction cavity for feeding a liquid into the cavity for mixing with the substance to form a beverage mixture; and
a fluid exit associated with the extraction cavity for extracting the mixture.
