[0109] FIGS. 14a-14h different solutions for a connection region with corresponding connection structures;
[0110] FIGS. 15a-15f different solutions for a connection region with corresponding connection structures.
[0111] In the following description, the same reference numerals are used for equal and equally acting parts.
[0112] FIG. 1 shows a child transport device 9, comprising a child receiving device 10 as well as a connection device 11, which can be pushed by a pusher 12 and forms a pram.
[0113] The connection device 11 according to FIG. 1 is designed as a front wheel fork. In this respect, the connection device 11 comprises a front wheel 13. The child receiving device 10 has two rear wheels 14 (only one of which is visible in the side view), a cabin 15 as well as a frame 16 which can be changed via at least one joint 16a. In the cabin 15 at least one (i.e. exactly one or more than one), or at least two (i.e. exactly two or more than two), child(ren) can be accommodated.
[0114] FIG. 2 shows the child receiving device 10 in a different configuration from FIG. 1. Among other things, the front wheel fork has been replaced here by a different connection device 11 in the form of a pull bar or trailer hitch compared to FIG. 1. As can be seen, the configuration of the child receiving device according to FIG. 2 further differs from the configuration according to FIG. 1 in that frame 16 or cabin 15 (in particular in a rear region) are lower and (which is optional) the pusher 12 is folded down or towards a main body of the child receiving device 10 (so that it is not in the way) compared to FIG. 1.
[0115] Specifically, the respective connection device 11 according to FIGS. 1 and 2 is connected to (or attached to) the child receiving device 10 at a connection region 17. The connection region 17 is part of the child receiving device 10.
[0116] FIG. 3 shows the child receiving device 10 in the configuration according to FIG. 2, whereby the child receiving device 10, in contrast to FIG. 2, is connected to another pull transmission device (pull bar) as the connection device 11. This pull transmission device can be attached to a running person, for example.
[0117] FIG. 4 shows the child receiving device 10 basically in the configuration according to FIGS. 2 and 3, but in contrast to FIGS. 2 and 3, skids (or skis) 18 are attached instead of the rear wheels 14.
[0118] FIG. 5 shows the connection region 17 of the child receiving device 10 (which is not shown) as well as a connection device 11 in the form of a pull bar.
[0119] FIG. 6 shows the connection region 17 as well as the connection device 11 in a state connected with each other. FIG. 7 shows the connection device 11 (pull bar) according to FIGS. 5 and 6 in a view from above.
[0120] The connection region 17 according to FIGS. 5-7 has a first engagement structure 20a, a second engagement structure 20b and a third engagement structure 20c. The engagement structure 20a has a U-shaped receptacle. The engagement structures 20b, 20c are optionally formed as holes. Furthermore, the connection region 17 has a blocking device (blocking means, preferably cover plate or cover plate section) 21, which (as explained in more detail with reference to FIGS. 8-10 below) can be brought into alignment with the engagement structure 20c.
[0121] The connection device 11 in turn comprises a bar (or other engagement structure) 22 as well as a bar (or other engagement structure) 23. The bar 22 may be brought into engagement with the engagement structure 20a. When this is the case, the bar 23 may be engaged only with the engagement structure 20c, but not with the engagement structure 20b.
[0122] In particular, it may be provided that the bar 23 is first inserted into the engagement structure 20c with the bar 22 still initially spaced from the engagement structure 20a. The connection device 11 can then be rotated upwards so that the bar 22 rotates into the engagement structure 20a and is locked there by a locking mechanism (not shown).
[0123] This means (cf. FIGS. 8-9) that the connection device 11 (in the form of the pull bar) according to FIGS. 5-7 is not connectable to (or attachable to) the child receiving device 10 in a deviating configuration of the child receiving device 10, in which (as a result of the change in configuration) the blocking device 21 is in cover with the engagement structure 20c.
[0124] Such a configuration is schematically shown with reference to FIGS. 8-10. Specifically, this configuration may, for example, differ from the configuration according to FIGS. 5-7 in that the centre of gravity of the child receiving device 10 is higher in this case. As can be seen in FIG. 8, the blocking device 21 now blocks the engagement structure (opening or hole) 20c, but not the engagement structure 20b. The connection device 11 in the form of a front wheel fork, which can be seen in FIGS. 8 and 9, has bars (or other engagement structures) 22, 23 in principle analogous to the connecting device (pull bar) 11 according to FIGS. 5-7. Again, the bar 22 is engageable with the engagement structure 20a of the connection region 17. However, in contrast to FIGS. 5-7, the bar 23 of the connection device 11 according to FIG. 8-10 is closer to the bar 22, so that the latter can only be brought into the engagement structure 20b (which is also not blocked in FIG. 8-10). It can be seen that the connection device 11 (front wheel fork) according to FIGS. 8-10 would also be engageable with the connection region 17 in the configurations of the child receiving device 10 according to FIGS. 5-7.
[0125] In particular, it may also be provided here that at first the bar 23 is inserted into the engagement structure 20b, with the bar 22 still initially spaced from the engagement structure 20a. The connection device 11 can then be rotated upwards so that the bar 22 rotates into the engagement structure 20a and is locked there by a locking mechanism (not shown).
[0126] FIG. 11a shows (highly schematic) a connection region with an opening and a first blocking means, wherein the first blocking means is in a first position in which it does not influence the cross-section of the opening.
[0127] FIG. 11b shows the connection region with the opening and the first blocking means of FIG. 11a, whereby the first blocking means is now in a second position in which it reduces the cross-section of the opening.
[0128] FIG. 11c shows a second engagement structure (engagement element) of a connection device, the cross-section of the engagement structure (engagement element) being formed such that it can only engage the opening when the first blocking means according to FIG. 11a is in its first position.
[0129] FIG. 11d shows another second engagement structure (engagement element) of another connection device, the cross-section of this engagement structure (engagement element) being formed such that it can engage the opening regardless of the position of the first blocking means.
