Description

TECHNICAL AREA

[0001] The invention relates to a two-wheel carrier for a mobile child transporter. BACKGROUND

[0002] Child carriers, especially bicycle trailers or joggers, are frequently used to transport children safely and comfortably. At the same time, there is often a need to also transport a two-wheeled vehicle, such as a balance bike or bicycle.

[0003] Popular bicycle carriers are not optimally designed in terms of stability and safety when attaching the bicycle to the child carrier. Furthermore, the bicycle carrier can be cumbersome to use and may restrict a user's movement behind the child carrier or certain functions of the child carrier, thus impairing usability. SUMMARY

[0004] There is a need for a two-wheel carrier that at least partially eliminates the aforementioned disadvantages.

[0005] The object of the invention is to provide an improved two-wheel carrier for a mobile child transporter.

[0006] The problem is solved by the subject matter described in the independent claim. Advantageous further developments are the subject of the dependent claims.

[0007] According to one embodiment, a two-wheel carrier is designed for attachment to a child transporter. The mobile child transporter can be, for example, a bicycle trailer or a jogger. The two-wheel carrier has a support device configured to support a two-wheeler being transported from below. The support device has two wheel support sections. The two-wheel carrier has a retaining device to secure the two-wheeler carried on the support device against tipping sideways. The two-wheel carrier has a mounting arrangement for detachably attaching the support device to a frame assembly of the child transporter.

[0008] The carrying device can be designed so that, when attached to the child carrier, it is positioned in front of the axle of one of the child carrier's rear wheels when viewed from above, in the direction of travel. This can ensure that the transported bicycle does not restrict the child carrier's range of motion and guarantees stable positioning. In particular, this can shift the center of gravity of the transported bicycle in front of the axle, preventing the child carrier from tipping backward.

[0009] The mounting device can be attached, in particular, to an upper frame section of the frame assembly. The mounting device can be designed for positive locking on the frame assembly. The mounting device can allow the support device to be placed on the frame assembly from above and clamped to the frame assembly. This can enable a secure and stable attachment of the bicycle carrier to the child transporter.

[0010] The mounting arrangement can have two clamping sections, which can be configured to hold the frame assembly between them. In particular, the mounting arrangement can hold the upper frame section between them. At least one clamping section can be movable relative to the other clamping section to change the distance between the clamping sections. This can allow adaptation to different frame widths and ensure flexible mounting.

[0011] The bicycle carrier can have at least one actuating component that can be used to adjust at least one clamping section. This actuating component can, for example, be a threaded bolt. The two clamping sections can be configured to clamp the upper frame section in the area of ​​an upper frame joint and / or in the area of ​​an upper intermediate cross member of the upper frame section. The clamping sections can have recesses for receiving a portion of the frame section. The recesses can be shaped to match the frame joints, allowing the frame joints to be partially received in the recesses during clamping. This can enable precise and secure attachment of the bicycle carrier to the child transporter.

[0012] The mounting arrangement may include a support section, which may have a mounting section for bracing the support device against an upper rear transverse member of the frame assembly. The support section may project from the support device, for example, in the manner of a cantilever. This can provide additional stability and support for the support device.

[0013] The holding device can be coupled to the carrying device. For example, the holding device can be supported solely by the carrying device or coupled to the support section. In particular, the use of a holding device eliminates the need for child carrier components to laterally support a carried bicycle, thus not restricting the use of the child carrier. The holding device can be rotatably mounted. For example, the holding device can be rotatably attached to the support section. The holding device can be rotatable about an axis of rotation that runs transversely to the main direction of extension of the carrying device and / or, when mounted on the child carrier, in the direction of travel of the child carrier. This allows for flexible adjustment of the holding device to different positions and angles.

[0014] According to one embodiment, a two-wheel carrier is created in which the holding device can be attached separately and independently from the carrying device on the child carrier. This allows for flexible adjustment and positioning of the holding device and also prevents certain components of the child carrier, such as a handle, from being used only to a limited extent.

[0015] The mounting device can have a transverse mounting section for attachment to a rear upper transverse member of the child carrier frame. This transverse mounting section can have one or more swivel coupling sections for attachment to the rear upper transverse member. This allows for a secure and stable attachment of the mounting device to the child carrier.

[0016] The holding device can include a handle attachment section for mounting to a power application section of the child carrier that also has a handle section. The handle attachment section can have one or more swivel coupling sections for attachment to the power application section. This allows for flexible mounting of the holding device to the child carrier without restricting the actual function of the handle section or its accessibility.

[0017] The holding device can be arc-shaped. The holding device can, for example, be U-shaped. The free ends of the holding device can be designed for attachment to the force application section. The holding device can, in particular, be pivotably attached to the force application section. Each free end can have a swivel coupling section for attachment to the force application section. This allows for flexible adjustment of the holding device to different positions and angles.

[0018] The holding device may include a two-wheel coupling section, which can be designed for attachment to a two-wheel section. The two-wheel coupling section can, for example, be designed for attachment to the frame of the two-wheeler. The two-wheel coupling section may include a strap and a buckle, which may be configured to form a securing loop to hold the two-wheel coupling section to the two-wheel section. This can ensure a secure and stable attachment of the two-wheeler to the two-wheeler carrier.

[0019] The holding device can be designed as a support arm mounted on one side. The two-wheel coupling section can be located at the free end of the holding device.

[0020] Each wheel support section can have a wheel fastening device. The wheel fastening device can, for example, consist of a strap and a buckle. The support device can have a support profile. The support profile can, for example, be an aluminum support profile. The support profile can be trough-shaped. Each wheel support section can have a wheel tray.

[0021] According to one embodiment, a transport system is created which can include a child transporter and a two-wheel carrier attached to the child transporter.

[0022] The child transporter can have a frame assembly supported by wheel assemblies and forming a passenger compartment, comprising an upper frame section, a lower frame section, a rear connecting frame section, and a front frame section. A child seat can be provided in the passenger compartment. The upper frame section can have an upper right frame section and an upper left frame section. The upper right frame section can have an upper right front frame section and an upper right rear frame section connected to it via an upper right frame hinge. The upper left frame section can have an upper left front frame section and an upper left rear frame section connected to it via an upper left frame hinge. The upper right frame section and the upper left frame section can be connected via an upper rear transverse member.The upper right frame section and the upper left frame section can be connected in the area of ​​the frame joints by an upper intermediate cross member provided in front of the upper rear cross member. The child carrier can have two rear wheel assemblies with one rear wheel and at least one front wheel assembly with one front wheel. The wheel assemblies can be attached to the lower frame section. The child carrier can have a drawbar attachment section. The child carrier can have a power application section with a handle. BRIEF DESCRIPTION OF THE DRAWINGS
