Description

The invention relates to a cargo wheel for the transport of cargo and / or persons.

In recent years, cargo bikes have become established as an alternative to motor vehicles, especially in the inner city area, to transport loads and / or people. Examples of such cargo bikes are the Bullitt Cargo Bike and the cargo bike from Butchers & Bicycles. Also widely used are the cargo bikes from Christiana.

All these wheels have a relatively high purchase price, but are limited in their versatility. These vehicles are very bulky and are not dismantled for the layman. Because of this, e.g. a move or storage usually difficult.

For example, in some cargo wheels, trough-like seats are used both for transporting children and for transporting loads. At best, this can be seen as a compromise solution that lags behind the wishes of customers, both in terms of passenger safety and ease of loading.

Consequently, the invention has for its object to provide a cargo wheel for the transport of loads and / or people who can be used for a variety of purposes.

This object is achieved for the above-mentioned cargo wheel in that it is modular and with a rear part, which has a handlebar, a rear wheel, acting on the rear wheel drive and a saddle, with at least one central part, the at least one load - And / or person recording, and having a front part, which has at least one steerable front wheel, is provided, wherein the rear and the middle part and the middle and the front part are repeatedly releasably connected to each other.

This modular design allows different front, rear and middle parts or modules to be combined. This allows the cargo bike to be optimally fitted to its intended use.

The above object is also achieved by a kit for such a modular cargo wheel, wherein the kit further comprises at least one further different front part, which is designed repeatedly releasably connectable to the middle and / or the rear part, and / or at least one further different middle part, which is designed repeatedly detachably connectable to the rear and / or the front part, and / or at least one further different rear part, which is designed repeatedly releasably connectable with the middle and / or the front part has.

By such, for example, provided by a seller kit, the modular cargo bike can be adapted to a specific task, such as the transport of people by a specially trained for this middle part to the front and rear part is purchased. The same buyer may, after some time, when the children have outgrown the transport of passengers by the cargo wheel, replace the middle part with a central part specialized in the transport of loads or attach another middle part. Alternatively or additionally, a rear part, which can only be driven by muscle power, can be exchanged for a rear part provided with an electric assist motor. Likewise, the dismantled components can be easily transported and stored easily when not in use.

The solution according to the invention can be further improved by the following developments, which are each advantageous and which can be combined with one another as desired.

Thus, as already mentioned, the drive may comprise an electric motor. In such a case, the energy source, for example a battery or an accumulator, is preferably fastened to the rear part. The drive may have pedals in addition to the electric motor or without an additional electric motor.

The parts of the cargo wheel may be connected to one another via preferably mechanically complementary or identically configured mechanical interfaces, for example abutting flange surfaces or positive connections such as T or dovetail profiles. The flange surfaces can be oriented perpendicular to the direction of travel and / or parallel to the direction of travel. The advantage of flange surfaces, which are oriented perpendicular to the direction of travel, lies in a shorter design.

The parts or modules can be screwed together. However, a tool-free connection can also be advantageous, for example via a coupling mechanism which has a quick-release with an eccentric or a cam follower.

According to a further advantageous embodiment, the front part may be provided with its own headset or steering head bearing. As a result, the front wheel is fixed in the front part and rotatably held. The connection between the parts is preferably fixed.

A separate, separate headset is preferably provided on the handlebar of the rear part.

About a steering gear, the handlebar or the rear part steering movements are transmitted coupled to the front part or the front wheel. In this way, the steering movements are transmitted to the front wheel despite the intermediate middle part. The kit preferably includes different elements of the steering gear to accommodate different sizes and shapes of the front, middle and rear parts.

The steering gear can in particular have a steering linkage and / or a traction mechanism, for example a chain or a toothed belt drive, in order to transmit the steering movements. To connect differently designed front and rear parts together or to bridge different sized middle parts, the kit may have differently designed steering linkage and / or traction means. A traction mechanism, such as a belt drive or chain drive, for transmitting the steering movements from the rear to the front part has the advantage that in different configurations of the cargo wheel only the length of the traction means must be adjusted.

The steering gear bridges the middle part preferably without contact. This simplifies the construction of the middle part, since no fastening and / or guide means for the steering gear must be provided.

The front part may be configured in a multi-track in a further advantageous embodiment. A multi-track front part has at least two jointly steerable, mutually parallel front wheels, which are spaced apart from each other transversely to the direction of travel. The multi-lane, sufficient here is already a two-lane, leads to a significant improvement in the stability of the cargo wheel, which can barely or no longer tip over. The multi-lane also allows for higher loads a higher center of gravity, without making the cargo bike is difficult to balance. Preferably, at least one section is located between the at least two front wheels of the multi-track part, in which load and / or at least one person can be accommodated. A multi-track front part preferably has a parallelogram with tilting technique.

The kit of the modular cargo wheel may include such a multi-lane front part and alternatively a single lane front part.

The middle part can have a platform and / or a frame and / or a tub as a load and / or transport receptacle.

In a further advantageous embodiment, the rear part is repeatedly releasably fastened, omitting the middle part at the front part. This results in a short bike, which in the case of a single-lane front part has the maneuverability of a normal bicycle. If a multi-lane front part is used, a tip-over bicycle for seniors is created. In mutually complementary or identically designed interfaces between the parts, the front part according to an advantageous embodiment directly, in particular without intermediate adapter pieces, be attached to the rear part.

A cargo and / or passenger seat of the middle part may extend at least in sections over the at least one front wheel. In this way, the entire length of the bicycle can be used to transport loads and / or people. In a multi-lane bicycle, the cargo and / or passenger receptacle may extend between the front wheels.

The connection between the front and the middle part, the middle and the rear part and / or the front and the rear part is preferably at least sufficiently rigid in order to give the frame a sufficient rigidity even under high load.

The range of use of the cargo wheel can be further increased if at least one middle part or at least the middle part of the modular cargo wheel or at least a middle part of the kit is equipped with a rail fastening system. The kit may in this case have interchangeable and / or mountable transport aids, which are preferably designed to be displaceable on the mounting rail system, but in any case lockable, fastened. Such transport aids can be transport boxes of different sizes and shapes, pans of different sizes and shapes and / or seats of different sizes, especially child seats, as well as lashing devices. A smaller form of the kit can also hold only one size of these different transport aids. The seats can accommodate one or more persons and are preferably connected to a restraint system. Preferably, the seats are fastened in and against the direction of travel. As well on front part may be provided fastening devices for such transport aids.

The invention is explained in more detail below with reference to an exemplary embodiment.
