By means of the configuration according to the invention, a high level of operational reliability can advantageously be achieved, in particular with regard to operational reliability against an unintentional detachment of the transport device from the transport track during high driving dynamics as a result of an unintentional relative movement of the coupling elements. It can advantageously enable the coupling elements to be securely held in a relative position to one another in order to counteract a detachment of the transport device due to operating forces.It is advantageous to realize a structurally simple movement of the coupling elements into a securing position and a holding of the coupling elements in the securing position.

[0010] The locking element is preferably provided to cause, limit, and / or block a movement of the coupling elements relative to one another, in particular along at least one longitudinal axis of the coupling elements, by means of a positive and / or non-positive connection with at least one of the coupling elements. For example, it is conceivable for the locking element to engage in a locking recess of the locking unit arranged on one of the coupling elements, in particular to be formed integrally with one of the coupling elements, for the locking element to be designed as a magnet, in particular as an electromagnet, and to be provided for exerting a magnetic force on at least one of the coupling elements, or for the locking element to have another configuration that appears appropriate to a person skilled in the art in order to cause, limit, and / or block a movement of the coupling elements relative to one another."Intended" should be understood in particular as specifically configured, specially designed, and / or specially equipped.

[0011] The coupling elements are provided in a manner already known to a person skilled in the art to enable coupling or decoupling of the transport device to the transport track depending on a movement or a position of the coupling elements relative to one another. Preferably, when the coupling elements are retracted, the transport device can be removed from the transport track or arranged on the transport track. In particular, when the coupling elements are extended, the transport device is secured to the transport track. Preferably, one of the coupling elements is movably mounted by means of the other of the coupling elements. One of the coupling elements is preferably designed as a guide sleeve in which the other of the coupling elements, designed in particular as a guide tube, guide bolt, guide pin or the like, is guided, in particular movably mounted.The coupling element, in particular the inner one, and the other, in particular the outer one, preferably form a coupling pair. The guide unit preferably comprises at least two coupling pairs. However, it is also conceivable for the guide unit to comprise more than two coupling pairs. The guide unit preferably comprises at least one spring element, in particular a helical spring or the like, which is intended to apply a spring force to at least one of the coupling elements, in particular both coupling elements, acting in particular along the longitudinal axes. The coupling elements are preferably movably mounted in a spring-loaded manner by means of the spring element. The spring element is preferably intended to apply a spring force to the coupling elements in directions pointing away from one another.

"Substantially parallel" is to be understood in particular as an alignment of a direction relative to a reference direction, in particular in a plane, wherein the direction has a deviation from the reference direction of in particular less than 8°, advantageously less than 5°, and particularly advantageously less than 2°.

[0014] Furthermore, in particular in at least one embodiment of the transport device, it is proposed that the blocking element be pivotably mounted and have a movement axis that runs transversely, in particular at least substantially perpendicularly, to, in particular to the aforementioned longitudinal axes of the coupling elements, along which the coupling elements are movably mounted relative to one another.

If no specific distinction is made between the inner and outer coupling elements, the description of functions and configurations should generally apply to all coupling elements of the guide unit. However, it is also conceivable that the functions and / or modes of operation of the inner coupling element described herein can also be carried out at least partially by the outer coupling element and vice versa, in particular a guiding function, an operative connection with the locking element, or the like. A person skilled in the art will interpret the functions and / or effects relevant to them accordingly as also applying to the inner or outer coupling element, particularly depending on the intended use of the transport device.Preferably, the inner coupling element is at least largely surrounded by the outer coupling element along a circumferential direction, in particular based on a total circumferential extent of the inner coupling element.

However, it is also conceivable for the locking unit to comprise a coupling element, by means of which the actuating element can be non-rotatably connected to the fixing element in at least one state by force and / or form-lock. The coupling element can be designed as a multi-disk clutch, a centrifugal clutch,be designed as a magnetic coupling or the like. A rotationally fixed connection between the actuating element and the fixing element by means of the coupling element can be dependent on the magnitude of the actuating force acting on the actuating element. If the actuating force acting on the actuating element exceeds a limit value, for example, a rotationally fixed connection can be established between the actuating element and the fixing element by means of the coupling element. If the actuating force acting on the actuating element falls below a limit value, for example, no rotationally fixed connection can be established between the actuating element and the fixing element, but the actuating element remains movable relative to the fixing element. Alternatively or additionally, it is conceivablethat a rotationally fixed connection between the actuating element and the fixing element by means of the coupling element is dependent on a length of a movement path of the actuating element relative to the fixing element.
