1. A brewing apparatus for extracting a portion capsule, having a first brewing chamber element and a second brewing chamber element, wherein at least one of the first brewing chamber element and the second brewing chamber element is movable along an axial direction from a loading position, in which the first brewing chamber element and the second brewing chamber element are spaced apart from one another, into an extracting position, in which the first brewing chamber element and the second brewing chamber element form a substantially closed brewing chamber; wherein the brewing apparatus displays a drive mechanism for moving at least one of the first brewing chamber element and the second brewing chamber element, wherein the brewing apparatus displays a separate locking mechanism for locking the brewing chamber in the extracting position;wherein the locking mechanism is a roller-shaped or ball-shaped latch; andwherein a first wall of a wall part of the brewing apparatus displays at least one first chamfer, and a second wall of displacing element displays at least one second chamfer;wherein the first chamfer, the second chamfer, and a retaining element of the first brewing chamber element contact the latch of the locking mechanism in a locking position. 2. The brewing apparatus as claimed in claim 1, wherein the drive mechanism displays a drive element which is configured to be selected from a group consisting of a toggle lever joint, a gear rack, a spindle, or a pivot gear. 3. The brewing apparatus as claimed in claim 1, wherein the drive mechanism is selected from a group consisting of a drive mechanism that is manually actuatable by means of a hand lever or a drive mechanism that is automatically drivable by means of a drive motor. 4. The brewing apparatus as claimed in claim 1, wherein, for locking the brewing chamber in the extracting position, the locking mechanism is transferable from a releasing position into the locking position. 5. The brewing apparatus as claimed in claim 1, wherein the first brewing chamber element displays a retaining element, at least one return spring, and a displacing element, wherein the retaining element and the displacing element are connected by means of a return spring and wherein the retaining element is displaceable in relation to the displacing element. 6. The brewing apparatus as claimed in claim 1, wherein the locking mechanism displays at least one latch, and that the at least one latch in a releasing position is displaceable along the axial direction between the first brewing chamber element and a wall part. 7. The brewing apparatus as claimed in claim 1, wherein the second chamfer is configured in such a manner that, in an event of the locking mechanism being transferred from a releasing position into the locking position, a movement of the latch in a transverse direction, which is perpendicular to the axial direction, into a cavity which is formed by the first chamfer and the second chamfer is caused. 8. The brewing apparatus as claimed in claim 1, wherein an arrester is configured such that during an extracting process a returning force which acts counter to the axial direction from a retaining element on the latch, which is located in the locking position, is absorbed by the first chamfer. 9. The brewing apparatus as claimed in claim 1, wherein the latch of the locking mechanism displays a sliding face for sliding on a guiding face of a displacing element of the first brewing chamber element. 10. The brewing apparatus as claimed in claim 1, wherein the drive mechanism displays a hand lever and a toggle lever joint, wherein the hand lever displays a first coupling part and the toggle lever joint displays a second coupling part, wherein, in order to transmit a movement of the hand lever to a movement of the toggle lever joint, the first coupling part and the second coupling part are in operative interconnection by way of a gear wheel connection. 11. The brewing apparatus as claimed in claim 10, wherein the toggle lever joint displays a first toggle lever and a second toggle lever, wherein the first toggle lever displays the second coupling part, and the second toggle lever, on a first side, is rotatably connected to the first toggle lever, and, on a second side, is displaceably disposed along the axial direction. 12. A method for operating a brewing apparatus as claimed in claim 1, wherein, in a first method step, at least one of the first brewing chamber element and the second brewing chamber element is moved along an axial direction from a loading position, in which the first brewing chamber element and the second brewing chamber element are spaced apart from one another, into an extracting position, in which the first brewing chamber element and the second brewing chamber element form a substantially closed brewing chamber, and in a second method step, in order for the brewing chamber to be locked by means of the locking mechanism, which is transferable from a releasing position into a locking position in order for the brewing chamber to be locked in the extracting position, a latch of the locking mechanism is displaced in a transverse direction which is perpendicular to the axial direction and/or the latch is pivoted about a pivot axis which is perpendicular to the axial direction. 13. The method as claimed in claim 12, wherein in a third method step, in order for the brewing chamber to be unlocked by means of the locking mechanism, the latch of the locking mechanism is displaced in the transverse direction, and, in a fourth step, at least one of the first brewing chamber element and the second brewing chamber element is moved back along the axial direction, from the extracting position into the loading position. 14. The method as claimed in claim 12, wherein, during the first method step, the latch is displaced in the axial direction from a second chamfer of a displacing element of the first brewing chamber element, and, during the second method step, the latch is displaced in the transverse direction from the second chamfer into a cavity which is formed by a first chamfer of a wall of the brewing apparatus and by the second chamfer, and during an extracting process a returning force which acts counter to the axial direction from a retaining element of the first brewing chamber element on the latch, which is located in the locking position, is jammed in the cavity between the first chamfer, the second chamfer, and the retaining element. 15. The method as claimed in claim 12, wherein, during a third method step, the latch is moved by a first chamfer of a wall of the brewing apparatus in the transverse direction out of a cavity which is formed by the first chamfer and a second chamfer of a displacing element of the first brewing chamber element, and, in a fourth method step, the latch is displaced counter to the axial direction by a retaining element of the first brewing chamber element. 16. The method as claimed in claim 12, wherein during the first method step, a sliding face of the latch is displaced on a guiding face of a displacing element of the first brewing chamber element. 17. The method as claimed in claim 12, wherein during the second method step, the latch is pivoted in such a manner that one end of the latch engages in an opening of a wall part and/or is blocked in relation to a movement in the axial direction by at least one blocking element.
