Description

The invention relates to a load scooter according to the preamble of claim 1, ie, a load scooter in the form of a scooter with a running board, in each case at least one wheel mounted on opposite ends of the footboard and a steering device at one end of the footboard in the region of at least one wheel is provided for steering at least one wheel, wherein the footboard is configured such that a first part of the footboard for transporting a load formed and a second part of the footboard relative to the first part is adjustable so that the load roller can be used as a kind of trolley , Such a load roller is in the DE 9302169 U1 described.

Furthermore, in the EP1704901A1 describes a scooter consisting of a running board, a hand rest and arranged on the running board roles in which the scooter rider stands on the running board with one foot and repels with the other foot on the ground. The hand rest is arranged on the running board in such a way that it divides the running board into a longer foot rest area located behind the hand rest and a shorter luggage rest area located in front of the hand rest.

The DE10057322A1 also describes a device for transporting loads with a chassis having at least two wheels arranged on an axle, to which at least one container for receiving a transport good can be fastened. The device has a releasably and / or pivotally mounted on the chassis, a substantially parallel to the floor arranged footboard and at its rear end facing away from the chassis at least one further wheel having scooter.

DE8128047U1 further describes a three-wheeled transportation vehicle. The front wheel can be controlled via a handlebar. At least one luggage surface is arranged above the front wheel. A trained as a running board rear part is wholly or partially folded up.

From the WO01 / 72164A1 is a piece of luggage with at least two roles known that allows movement by means of the luggage according to the use of a scooter. At least one of the rollers is engageable and lockable in an operative position spaced from the projection surface of the item of luggage, wherein the positionable roller is an operative position supporting the item of luggage via a tread usable sheet element is attached to the luggage.

For the transport of small loads in walking distance there are also so-called (shopping) trolleys: 2-wheeled car with handle, to which a container is attached, in which the load can be placed. For transporting smaller loads bicycles are often used with panniers or boxes. It is also known to use devices for attaching shopping baskets etc. to ferry wheels. However, the aforementioned solutions for the transport of goods have the following disadvantages: A trolley can indeed take in the apartment, the way to the shop and back but can be covered only slowly, usually with pedestrian speed. Although the bicycle allows a higher travel speed than the trolley, but in contrast to the trolley, especially in urban areas often too bulky, for example, in department stores.

An object of the present invention is now to propose a load roller, which allows the relatively quick and easy transport of loads.

This object is achieved by a load roller with the features of claim 1. Preferred embodiments of the invention will become apparent from the dependent claims.

The load roller is designed in the form of a scooter, in which the footboard is specially designed for the transport of loads. Such a load roller combines two functions, namely a scooter for fast moving as well as a trolley for comfortable and easy transport of loads. With such a scooter, short distances can be covered just as fast as with a bicycle. In order to allow a load transport in tight areas, such as the sales or cash room of a department store or grocery store, or in a stairwell, an elevator or apartment, the scooter used as a scooter, which may be too bulky in such a space, for Trolley can be "rebuilt" by the footboard of the freight scooter is adjusted so that the scooter has smaller overall dimensions. For example, the footboard can be partially folded or pushed in, and a load can now be transported as with a normal compact shopping trolley. Due to the partially folded or inserted footboard also a load to be transported on the running board can be secured against falling from the scooter.

The invention now according to one embodiment relates to a load scooter in the form of a scooter with a running board, each with at least one mounted on opposite ends of the footboard wheel, and a steering device to the one end of the footboard in the region of at least one wheel for steering at least one wheel is mounted, wherein the footboard is configured such that a first part of the footboard for transporting a load formed and a second part of the footboard relative to the first part is adjustable so that the loader can be used as a kind of trolley. The first part comprises a bogie on which is pivotally mounted about a vertical axis a load platform on which the steering device and at least one wheel are mounted.

According to one embodiment of the invention, the second part may be fixable in a first position relative to the first part, in which the load roller has a scooter function, and the second part may be fixable in a second position relative to the first part, in which the load roller has a trolley function.

In particular, according to an embodiment of the invention, the second part of the footboard can be hingedly attached to the first part, and for transporting a load the second part can be folded up and fixed in the folded-up position.

Alternatively or additionally, according to a further embodiment of the invention, the second part of the footboard can also be designed to be slidable onto or insertable into the first part.

The first part comprises a bogie on which is pivotally mounted about a vertical axis a load platform on which the steering device and at least one wheel are mounted. As a result, the maneuverability and steerability of the load roller can be improved.

So that the load roller does not fall over with the load, it can be equipped with three wheels. In this case, a pair of wheels can be arranged at the front or rear of the load roller.

Above all, according to one embodiment of the invention, the steerable by the steering device at least one wheel to be a pair of wheels, whereby a high driving stability of the freight scooter is achieved. For steering the loader but also a single wheel can be used. It may also be a vertical pivot, similar to a wheel loader, be provided between the wheels for steering.

To improve the driving dynamics, the load roller according to an embodiment of the invention may be designed such that it can be tilted when cornering.

In particular, in accordance with an embodiment of the invention, a bevel gear transmission may be provided to permit skewing of the load roller when cornering; the gear is provided to control the position of stub axles, to each of which a wheel is mounted.

In a further embodiment of the invention, the load roller may be designed such that when cornering either only the footboard tilts, or tilt the footboard and a load.

Finally, in one embodiment of the invention, the load roller may have an additional motor drive to be able to carry, for example, particularly heavy loads simply and easily.

Further advantages and possible applications of the present invention will become apparent from the following description in conjunction with the embodiment shown in the drawings.
