Machine for preparing and extracting a hot beverage

A machine for preparing and extracting a hot beverage from a capsule;

• the machine comprising:
• a load-bearing frame having an inlet opening for the capsule;
• a first fixed extraction unit associated with the frame and comprising a matching housing for the capsule and configured to obtain the extraction of the beverage;
• a second movable extraction unit, positioned inside the frame, and movable inside the frame along a linear trajectory, in both directions, between a first non-operating wherein the second movable extraction unit is positioned close to the inlet opening, and a second operating end position wherein the second movable extraction unit is moved towards the first fixed extraction unit to move the capsule inside the housing;
• a pair of supporting arms interposed between the second movable extraction unit and the frame;
• said pair of arms being movable with the second movable extraction unit and along the frame in such a way as to move from a first near operating end position and configured to support the capsule entering, in the first non-operating position of the second movable extraction unit, to a released configuration from the capsule, in a relative second far operating end position, in the second operating position of the second movable extraction unit;
• characterised in that each arm is articulated, in a relative articulation zone, in a matching seat made directly on the second movable extraction unit;
• each articulation zone being provided with a pin for constraining in the corresponding seat in such a way as to define a pivot and rotation axis for the respective arm;
• each pin being provided, bilaterally, with two different contact heads protruding from the second movable extraction unit and configured to interact, through tear rotation about the axis, with tracks having cam profiles and made on the frame to move each arm between the first and second operating positions, and vice versa, during the movement of the second movable extraction unit.
