Embodiments according to the invention advantageously allow a high level of operational safety to be achieved, in particular with regard to an unintended separation of the transport device from the transport path due to an undesired relative movement of the coupling elements in high driving dynamics situations. Advantageously, the coupling elements are securely held in a relative position to each other in order to counteract a separation of the transport device caused by operating forces. Advantageously, a structurally simple movement of the coupling element into a fastening position and a holding of the coupling element in the fastening position can be achieved.

[0007] The blocking element is preferably configured to induce, limit and / or block the movement of the coupling elements relative to each other, in particular along at least one longitudinal axis of the coupling elements, by a form-fitting and / or force-fitting connection with at least one coupling element. For example, it is conceivable that the blocking element engages in a blocking recess of the blocking unit, the blocking recess being arranged on one of the coupling elements and in particular being implemented as a component with one of the coupling elements; the blocking element is implemented as a magnet, in particular as an electromagnet, and is configured to exert a magnetic force on at least one coupling element; or the blocking element has different embodiments that are considered suitable by a person skilled in the art to induce, limit and / or block the movement of the coupling elements relative to each other.

[0017] Furthermore, it is proposed that, alternatively or additionally, the transport device in particular comprises at least one receiving interface, in particular the above-mentioned receiving interface, for receiving a functional carrier, in particular the above-mentioned functional carrier, which can be arranged replaceably on the receiving interface, wherein the blocking unit comprises at least one movably supported fixing element, in particular the above-mentioned fixing element, for fixing the functional carrier, and the blocking unit comprises at least one actuating element, in particular the above-mentioned actuating element, for actuating the actuating element and the fixing element, in particular actuating according to the direction of movement of the actuating element. The actuating element is preferably supported so as to be movable about or along the actuating axis in two opposite directions of movement. In particular, the actuating element is supported so as to be pivotable about the actuating axis in two opposite directions of movement, in particular when the actuating element is embodied as an actuating lever. Preferably, starting from a fastening position of the actuating element, wherein the fixing element is arranged in the fixing position and the blocking element is arranged in the blocking position, according to a movement of the actuating element in one of the directions of movement, the fixing element can be moved to a release position, while the blocking element remains in the blocking position, and according to a movement of the actuating element in the other direction of movement, the fixing element remains in the fixing position and the blocking element can be moved to a release position. The actuating element is preferably supported to be movable relative to the fixed element. Preferably, in particular in at least one state, the actuating element can be connected to the fixed element in a non-rotatable manner by force-fitting and / or form-fitting connection. Preferably, according to the direction of movement and / or movement distance of the actuating element relative to the fixed element, the actuating element and the fixed element can be connected in a force-fitting and / or form-fitting manner, wherein, in particular, due to the abutment of the actuating element against the fixed element and the subsequent further movement of the actuating element along the direction of movement of the actuating element, the fixed element and the actuating element can move in conjunction. However, it is also conceivable that the blocking unit includes a coupling element, by which the actuating element can be connected to the fixed element in a non-rotatable manner by force-fitting and / or form-fitting connection in at least one state. The coupling element can be implemented as a thin film coupling, a centrifugal coupling, a magnetic coupling, etc. The non-rotatable connection achieved between the actuating element and the fixed element by the coupling element can depend on the size of the actuating force acting on the actuating element. If the limit value of the actuating force acting on the actuating element is exceeded, a non-rotatable connection can be formed between the actuating element and the fixed element, for example, by a coupling element. If the limit value of the actuating force acting on the actuating element is fallen below, it is not possible to produce a non-rotatable connection between the actuating element and the fixing element, but the actuating element remains movable relative to the fixing element, for example. Alternatively or additionally, it can be assumed that the non-rotatable connection between the actuating element and the fixing element achieved by the coupling element depends on the length of the movement distance of the actuating element relative to the fixing element. Embodiments according to the invention allow a structurally simple way to achieve a secure fixing of the functional carrier to the transport device, in particular to the carrier element.Preferably, the actuation of the two different fixed or moving elements is achieved by a separate actuating element. An easy-to-operate quick-change function of the transport device, in particular the transport path and / or the functional carrier is achieved by the carrier element in a structurally simple manner.
