Head assembly for brewing apparatus

1. A head assembly for a brewing apparatus, comprising:

(a) a lock assembly having a moveable first part and a stationary second part;

(b) a movable lid portion bearing the moveable first part of the lock assembly;

(c) a fixed base portion hinged to the moveable lid portion having a brewing cartridge opening and the stationary second part of the lock assembly; the moveable lid portion being rotatable between an open position for receiving the brewing cartridge, and a closed position for sealing the brewing cartridge between the fixed base portion and the moveable lid portion and lock the movable lid portion to the fixed base portion;

(d) the moveable first part of the lock assembly disposed on the moveable lid portion to provide a locked position for locking the fixed base portion to the moveable lid portion when the moveable lid portion is in the closed position, and an unlocked position for releasing the moveable lid portion from the fixed base portion and release the brewing cartridge;

(e) an axis point disposed between the hinged moveable lid portion and the moveable first part of the lock assembly to move the moveable first part of the lock assembly between the locked and unlocked positions;

(f) a cover or a handle movably coupled to the axis point disposed between the moveable first part of the lock assembly such that pressure on the cover or handle rotates the moveable lid portion to the closed position, and slides the moveable first part of the lock assembly into the locked position; and

(g) a brewing cartridge ejection mechanism to eject the brewing cartridge.

2. The brewing apparatus of claim 1 wherein the moveable lid portion is biased towards the open position.

3. The brewing apparatus of claim 1 wherein the moveable first part of the lock assembly is biased towards the unlocked position.

4. The brewing apparatus of claim 1 , further comprising an injection pin connected to the moveable lid portion for piercing the brewing cartridge in the closed position.

5. The brewing apparatus of claim 1 , further comprising:

a cartridge holder rotatably mounted within the fixed base portion and having a resting position for receiving the brewing cartridge, and an ejection position for ejecting a spent brewing cartridge.

6. The brewing apparatus of claim 5 , further comprising:

an arm having a first end fixed to the moveable lid portion and a second end configured to contact the cartridge holder;

wherein movement of the moveable lid portion from the closed position to the open position causes movement of the arm for contacting the cartridge holder and rotating the cartridge holder to the ejection position.

7. The brewing apparatus of claim 6 wherein the arm is configured to contact a dog rotatably connected to the cartridge holder, and wherein the dog is configured to resist rotation in a first direction for causing the cartridge holder to rotate, and then to rotate in an opposite second direction.

8. The brewing apparatus of claim 1 , further comprising:

a shuttle supporting an extraction pin and slideably mounted within the fixed base portion, the shuttle having a resting position and a brewing position for piercing a cartridge with an extraction pin;

wherein a slideable or pivotable plate is configured to engage the shuttle for sliding the shuttle to a brewing position.

9. The brewing apparatus of claim 8 wherein the extraction pin has a bend therein.

10. A head assembly for a brewing apparatus comprising:

(a) a latch mechanism having a moveable first part having a toothed rack assembly that is slideable and/or pivotable and a stationary second part;

(b) a first substantially flat plate having a hinge on one end and the moveable first part of the latch mechanism disposed at or near the other end of the first substantially flat plate;

(c) a second substantially flat plate having a first end hinged to said first substantially flat plate and bearing the stationary second part of the latch mechanism disposed in or on said second substantially flat plate;

(d) a brewing cartridge opening disposed between the first substantially flat plate and the second substantially flat plate;

(e) a cover or handle having a pinion gear connected to the toothed rack assembly and pivotally attached to said first substantially flat plate or said second substantially flat plate to open or close said first substantially flat plate with respect to the second substantially flat plate around said hinge and operate the moveable first part of the latch mechanism to engage the stationary second part and lock the first substantially flat plate to the second substantially flat plate and close the brewing cartridge opening; and

(f) a brewing cartridge ejection mechanism.
