• the rotatably mounted adapter, in particular the turntable, or the receiving device is assigned a switching element such as a slide, rotary knob, button, or push button or the like, with which the adjustable rotational positions or orientations of the receiving device can be fixed.
• the switching element can only be adjusted from a first switching position to at least one second switching position when the receiving device is not coupled to the adapter, in particular not fixed to the adapter.
• the rotatably mounted adapter is unlocked and the rotational positions or orientations of the receiving device can be freely determined if the switching element is in the first switching position.
• the receiving device can preferably be locked in a forward-facing position and in a rearward-facing position, provided that the switching element is in the second switching position.
• the receiving device can be designed not only for transporting a child, toddler or baby but also as a device for transporting animals or other objects.
• a stroller comprises a frame (stroller frame) and at least one receiving device.
• the receiving device is detachably connected to the frame, for example by means of at least one adapter which is / are provided on the frame for this purpose.
• the receiving device is preferably a child receiving device, in particular a seat unit, a reclining unit, a combined seat / reclining unit or a baby seat (suitable for transporting a toddler in a motor vehicle), but it can also be another transport device, e.g. a Shopping basket or other transport device for transporting objects act.
• the receiving device comprises complementary counterparts to the adapter on the frame or to the adapters on the frame, or it can be releasably connected to these via intermediate adapters.
• the frame can also comprise several adapters for fastening one or more receiving devices, preferably exactly one adapter or exactly one adapter pair per receiving device.
• an adapter is to be understood as that structure which is provided for connection to exactly one receiving device, even if it is, for example, a pair of adapter elements (e.g. a right and a left adapter element).
• a stroller within the meaning of this invention is also present in particular when adapters for several receiving devices are present, but only one receiving device is connected to the frame.
• At least one of the adapters and / or the counterpart of a receiving device preferably a child receiving device that can be connected in a forward and backward direction
• This is a central (advanced or independent) idea of the invention.
• the asymmetry makes it possible to differentiate the setting options available in the forward or backward direction of the child receiving device (with regard to the frame).
• at least either the adapter or the counterpart can essentially have a twofold rotational symmetry.
• the asymmetry is a deliberate deviation from this principle, which can in particular be designed structurally.
• it can be a protrusion or a recess, with a protrusion possibly also being designed to be movable, e.g. as a pin that can be pushed in.
• the asymmetry should preferably relate to the contact surface of the adapter and / or the counter structure.
• the child receiving device has a fixed projection, for example a rib, in the counter structure.
• the adapter has a groove in a front area in such a way that the child support device can only be connected to the frame in a forward direction but not in a rearward direction (or exactly the other way around). It goes without saying that the projection and groove can be interchanged.
• the frame can have at least two adapters (for fastening at least two receiving devices), in particular at least one lower and at least one upper adapter.
• the frame can have exactly two, namely a lower and an upper adapter.
• the lower adapter should be closer to the ground and / or closer to the front wheels than the upper adapter.
• the upper adapter should be adjustable between a front and a rear position on the frame. The adapter position can be adjusted in various ways, but preferably by moving it.
• the upper adapter has an asymmetry in its rear position that it does not have in the front position (or vice versa) by inserting an asymmetry element during the adjustment (during displacement) and caused by this between a rest position and an active position is adjusted, the asymmetry only interacts in the active position with the counterpart of the child restraint device (and e.g. prevents its attachment to the frame or restricts it to certain positions such as the sitting position), and does not interact with the counterpart of the child restraint device in the rest position.
• the frame has an adapter and the child receiving device has a counterpart, which enables a rotatable connection between the frame and the child receiving device.
• the rotation should take place around an essentially vertical axis.
• the child receiving device should be able to be locked in at least two, preferably exactly two, positions with respect to the frame. The two positions are particularly preferably a forward-facing and a backward-facing position.
• the child restraint device should have a switch that allows the child restraint device to be positioned between a first (for using the child restraint device with a maximum load of 15 kg) and a second position (for using the child restraint device with a maximum load of 22 kg).
• At the Switch can be, for example, a slide button or a rotary button or a push button or a toggle switch.
• the switch should preferably only be able to be adjusted from the first position to the second position and back when the child support device is completely detached from the frame. If the switch is in the first position, the child support device can be connected to the frame in all (both) lockable positions, and rotation is possible without restriction when the child support device is connected to the frame and the position lock is open. However, if the switch is in the second position, a connection is preferably only possible in a forward position of the child receiving device with respect to the frame; in addition, the rotation of the child receiving device with respect to the frame is not possible.
• the adapter of the frame has a recess or receptacle in its contact surface that is not rotationally symmetrical with respect to the essentially vertical axis of rotation.
• the contact surface of the counter structure of the child support device can accordingly have a corresponding asymmetry element which is sunk into the contact surface of the counter structure and thus assumes a rest position when the switch is in its first position.
• the asymmetry element By moving the switch to its second position, the asymmetry element can also be moved into an operative position in which it forms a projection with respect to the surrounding contact surface of the counter structure which, in the forward position of the child support device opposite the frame, interacts with the receptacle or recess in the adapter can, but in all other positions (especially in the rearward-facing position) blocks a connection between the child support device and the frame (because there is no receptacle or recess at the corresponding position of the contact surface of the adapter), and at the same time a rotation of the child support device relative to the Frame only allowed within the limits specified by the dimensions of the receptacle or recess, the receptacle or recess preferably being just as wide as the projection.
• the above-mentioned object is also achieved in particular by a system and / or an arrangement comprising the above stroller and at least or exactly one child in the first receiving device and / or at least one or exactly one child in the second receiving device.
• the above-mentioned object is also achieved in particular through the use of the above stroller and / or above system, with at least or exactly one child being placed in the first receiving device and / or at least one or precisely one child being placed in the second receiving device, preferably for accommodation and / or transporting the child (s).
