[0035] Fig. 13 is a perspective view of an embodiment of a bicycle according to the invention with two embodiments of a luggage carrier system according to the invention.

[0036] Figure 1 shows an embodiment of a coupling device 10 according to the invention, with Figures 2-3 showing exploded views of this coupling device 10 and Figure 5 showing a plan view of this coupling device 10. Figure 4 shows a detailed view of IV. from Figure 2.

[0037] The coupling device 10 comprises a base element 12. The base element 12 comprises a housing 18 and a base plate 20 connected to the housing 18 (see Fig. 2). The connection is made via three guide bushings 24, 26, 28 connected to the base plate, in particular centering them, which are received in receiving openings 25, 27, 29 of the housing 18 (see Fig.

[0038] 3).

[0039] A rotary latch 14 is arranged between the housing 18 and the base plate 20. The rotary latch 14 is rotatable (rotational movement shown by arrow 19, Fig.

[0040] 4) about a rotation axis 17 (see Fig. 4) formed by the screw 22. The screw 22 is guided through a receiving opening 27 of the housing 18 and screwably engages a thread (not shown) in the guide bushing 26 of the base plate 20 in order to thus implement a connection between the housing 18 and the base plate 20 (see Figs. 2-3).

[0041] The rotary latch 14 is pre-tensioned into a closed position by a leg spring 16 mounted in the housing 18, in which the rotary latch 14 protrudes from the base element 12 (see Fig. 5). In the rest position, the rotary latch is

[0042] 14 thus pre-tensioned in the closed position.

[0043] By means of a return device 13, the rotary latch 14 can be rotated into an open position against the pretension of the leg spring 16 (see Figs. 6-7). The return device 13 has a ramp 15 which is designed as a single piece with the rotary latch 14. By acting, in particular translationally (shown by arrow 41, Figs. 2 and 4) on the ramp 15 using a socket wrench 40, the rotary latch 14 is rotated inward with respect to the base element 12 against the pretension into the open position (see Figs. 6-7). In this open position, the rotary latch 14 is arranged, in particular completely, within the base element 12. In the open position, the rotary latch 14 thus protrudes less from the base element 12 than in the closed position, wherein the rotary latch 14 in particular does not protrude from the base element 12.

[0044] For defined, translational guidance of the socket wrench 40 onto the ramp

[0045] 15, the base element has a guide having a slot 30. The translational movement (cf. arrow 41, Figs. 2 and 4) of the socket wrench 40 is converted by the ramp 15 into a rotational movement (cf. arrow 19, Fig. 2), which leads to a rotation of the rotary latch 14 about the rotation axis 17. The translational axis (cf. arrow 41, Figs. 2 and 4) of the translational movement is in particular perpendicular to the plane of rotation of the rotary latch 14 and / or parallel to the rotation axis 17. By means of a blocking device having a grub screw 32, the rotary latch 14 can be fixed in the closed position, so that when the grub screw 32 is screwed in, for example, into the opening 34 of the rotary latch 14 (cf. Fig. 4), the rotary latch 14 is blocked against movement into the open position.

[0048] Furthermore, the coupling device 10 has a rear grip element 36 having a projection 37 for positive connection to a rear grip element receptacle 204 (cf. Fig. 11), in particular having an opening, of a luggage carrier 200 and / or a bicycle 1000. The rear grip element 36, in particular the projection 37, is designed to be inserted (cf. insertion direction shown by arrow 45, Fig. 8) into the rear grip element receptacle 204. After the rear grip element 36 has been inserted, a connection, in particular a locking connection, takes place via the rotary latch 14 for coupling, wherein the connection, in particular a locking connection, preferably takes place via a locking movement (shown by arrow 43, Fig. 8). The locking movement is in particular parallel, preferably coaxial, to the translational movement of the socket wrench 40 and / or perpendicular to the insertion direction of the rear grip element 36 and / or perpendicular to the plane of rotation of the rotary latch 14.The rear grip element 36 and the housing 18 are connected to one another, in particular in one piece, via a basic structure 101 of a load receiving means 103 of the transport device 100.

[0049] The load-carrying device 103 has a basket structure 102 for holding objects to be transported. The load-carrying device 103 is thus depicted as a basket.

[0050] Figure 9 shows the transport device 100 from Figure 8 from above.

[0051] The slot 30 and the opening 25 for the grub screw 32 are accessible from the receiving area of ​​the load receiving device 103, in particular from above.
