The loading platform (102b1) comprises extension elements for lifting the loading platform (102b1).

Description

field of use

The invention relates to a parkable interchangeable container or trailer which for this purpose has support legs which can be swung out, the interchangeable container or trailer preferably being able to be picked up and transported by a cargo bike.

Technical background

• Dabei verfügen die bekannten Übersee-Container - die auf der Ladefläche eines LKW aufsitzend mittels der bekannten Twistlocks verriegelt werden - zur Verwendung als Wechselcontainer zusätzlich über schwenkbare Stützbeine, die im deaktivierten Zustand in eine horizontale Lage am oder unter dem Boden des Wechselcontainers herangeklappt sind, und - meist manuell - in eine vertikale, nach unten weisende aktivierte Lage, die Stützposition, verschwenkt werden können.

So-called interchangeable containers are already known from the truck sector:

• The well-known overseas containers - which are locked on the loading area of a truck by means of the known twistlocks - also have swiveling support legs for use as interchangeable containers which, when deactivated, are folded into a horizontal position on or under the floor of the interchangeable container, and - mostly manually - can be pivoted into a vertical, downward-pointing activated position, the support position.

If the usually four support legs attached to such an interchangeable container are folded down into the support position, the interchangeable container can be placed on the ground by lowering the support legs and after releasing the lock on the truck, i.e. usually after releasing the twistlocks, the Drive the truck out from under the elevated interchangeable container and perform other transport tasks.

The lifting of the interchangeable container necessary for this purpose before the support legs are folded down into the vertical support position and the subsequent lowering of the interchangeable container with the extended support feet until it is placed on the ground is usually achieved by means of the air suspension of the truck, as is the case with Saddling up such a parked interchangeable container necessary lifting of the interchangeable container and its support legs from the ground.

In the same way, it is necessary to support a so-called trailer, i.e. a semi-trailer attached to a towing vehicle in the coupled state by means of kingpins and a fifth wheel, in the front area if it is to be parked and the previous towing vehicle is to be uncoupled from the trailer.

In the inner-city area, transport tasks are increasingly taken over by cargo bikes, or also by relatively small, often electrically powered, four-wheeled transporters, whereby there is also a need for transportable, smaller, parkable and saddle-up swap containers or trailers.

Here, too, the cargo bike or vans should have a loading area that can be arranged in front of or behind the driver's seat in the case of a cargo bike, and with which the cargo bike or the vans can drive under a raised interchangeable container and saddle it up.

However, neither a cargo bike nor such a small transporter have air suspension with which the height of this loading area above the ground can be changed in a controlled manner in order to saddle up or uncouple an interchangeable container. In addition, the height of the loading area can be changed by external factors such as the weight of the driver or the fact whether the driver is currently sitting on the cargo bike or not.

• - entweder die Ladefläche des Lastenfahrrades oder Kleintransporters gegenüber dem Untergrund mit anderen Mitteln in ihrer Höhe gesteuert veränderbar sein
• - oder die Stützbeine als längenveränderbare Hubbeine ausgebildet sein, die auch in der Lage sind, einen gefüllten, schweren Wechselcontainer von der Ladefläche des Fahrzeuges aus hochzustemmen,

wobei die vorliegende Anmeldung den erstgenannten Fall betrifft.In this case must

• - Either the loading area of the cargo bike or the van can be changed in a controlled manner with respect to the ground by other means
• - or the support legs can be designed as adjustable lifting legs, which are also able to lift a filled, heavy swap container from the loading area of the vehicle,

the present application relates to the former case.

The same applies in the second case mentioned for the support legs at the front end of a trailer, with the top of the fifth wheel coupling on the towing vehicle then corresponding to the aforementioned loading area.

• - ein Trailer zum Abstellen mindestens zwei Stützbeine, je einen beidseits seiner Längsmitte im vorderen Bereich, da der hintere Bereich durch die Räder der Hinterachsen abgestützt bleibt, während
• - ein Wechselcontainer mindestens drei Stützbeine benötigt, und in der Regel vier Stützbeine besitzt, die in der Regel jeweils in den vier Eckbereichen der in der Aufsicht betrachtet in aller Regel rechteckigen Wechselcontainer angeordnet sind.

Needed accordingly

• - A trailer for parking at least two support legs, one on each side of its longitudinal center in the front area, since the rear area remains supported by the wheels of the rear axles while
• - An interchangeable container requires at least three support legs, and usually has four support legs, which are usually arranged in the four corner areas of the interchangeable container, which is generally rectangular when viewed from above.

Presentation of the invention

Technical task

It is therefore the object of the present invention to offer a solution to the problem described.

Solution of the task

The object can be achieved in that the loading area of the vehicle moving the interchangeable container or trailer, i.e. the cargo bike or small van, can be adjusted in height without the need for air suspension.

In particular in the case of a cargo bike, the wheels supporting the loading area and located next to one another in the transverse direction can preferably each be mounted on a swing arm, by means of which the suspension of these wheels is also implemented, for example by means of a torsion bar that connects the two swing arms on their swing axis connects.

• - entweder die vorzugsweise gemeinsame Schwingen-Achse in ihrer Höhe verlagerbar ist, beispielsweise mittels eines in der Länge veränderbaren Elementes, insbesondere einem Elektrozylinder oder einer Gewindespindel
• - oder die Schwenkstellung der Schwinge um die Schwingen-Achse veränderbar ist, was insbesondere ebenfalls mittels eines in der Länge veränderbaren Elementes, insbesondere einem Elektrozylinder oder einer Gewindespindel, realisierbar ist, sofern dieser exzentrisch zur schwingen-Achse an einem daran befestigten Hebel angreift.

The height of the loading area can then be changed in a simple manner by

• - Either the preferably common rocker axis is displaceable in its height, for example by means of an element that can be changed in length, in particular an electric cylinder or a threaded spindle
• - Or the pivot position of the rocker around the rocker axis can be changed, which can also be achieved in particular by means of an element that can be changed in length, in particular an electric cylinder or a threaded spindle, provided that it engages a lever attached to it eccentrically to the rocker axis.

In this way, the interchangeable container to be parked only requires simple, in particular pivotable, support legs which can be adjusted from a deactivated to an activated position and vice versa, and which in particular do not have to be extendable.

The 1a - c show a cargo bike 100 with a loading platform 102b1 in the rear area for loading a load, here an interchangeable container 1 , and on the interchangeable container 1 in the lower area, in particular under its underside, viewed from above in the corner areas, arranged activatable and deactivatable support legs 2 for parking the interchangeable container 1 on the underground.

• Es besteht aus einem vorderen Fahrerteil 102a, dem Vorderteil, an den sich hinten ein Lastenteil 102b anschließt, dessen Rahmen eine Ladeplattform 102b1 umfasst, welche sich auf dem Untergrund über zwei nebeneinander angeordnete Räder 117 abstützt und auf der Oberseite einen darauf aufgesetzten und verriegelten Wechselcontainer 1 aufnehmen kann.

First the cargo bike should be briefly described:

• It consists of a front driver part 102a , the front part, to which a load part is attached at the back 102b connects, the frame of which is a loading platform 102b1 includes, which is on the ground via two wheels arranged next to each other 117 and a lockable interchangeable container placed on top of it 1 can accommodate.

• - ein Sattelrohr 104 und ein Unterrohr 106, die in der Seitenansicht von der Tretkurbelachse 112 aus V-förmig auseinanderlaufen,
• - und in deren unteren Treffpunkt wie üblich auf der Tretkurbelachse 112 die beidseitigen Tretkurbeln 111 befestigt sind, die jeweils ein Pedal tragen und durch Treten ein Kettenrad 113 in Drehung versetzen,
• - welches in diesem Fall über eine Kette 114 einen ebenfalls am Rahmen des Fahrerteils 102a angeordneten Generator 115 antreibt.

The front driver part 102a has a frame that differs from that of a bicycle from the front end up to and including the seat tube 104 does not distinguish, so includes

• - a seat tube 104 and a down tube 106 the side view of the crank axle 112 diverge from a V-shape,
• - and in their lower meeting point, as usual, on the crank axle 112 the cranks on both sides 111 are attached, each wearing a pedal and by stepping a sprocket 113 set in rotation,
• - which in this case via a chain 114 one also on the frame of the driver's part 102a arranged generator 115 drives.

Seat tube 104 and down tube 106 are due to a very low top tube 103 braced against each other, and at the top of the down tube 106 is the head tube as usual 105 welded on, in which rotatable from the handlebar 108 up to the fork for the front wheel 101 front wheel unit extending therethrough is mounted.

At the top of the seat tube 104 the saddle is located as usual 107 so that the driver is in front of the load, here the swap body 1 , sits.

From this lower junction of the seat tube 104 and down tube 106 a girder extends out 102a1 in the form of a pipe horizontally and lengthways 10 to the rear, and is with the loading platform 102b1 articulated via a joint 110 showing the relative twisting of the loading platform 102b1 around the longitudinal axis 10 ' of the joist 102a1 compared to this allows.

The rear wheels 117 are electrically driven or at least electrically assisted, including that of the generator 115 The electricity supplied is fed to the electric motor or the battery that runs the rear wheels 117 drives.

Each of the support legs 2 has a leg brace 4th and can be accessed from the in 1a shown transport position in which the leg brace 4th runs approximately horizontally, and each with its free end and the local footplate 5 towards the rear wheels 117a , b points to a horizontal in the transverse direction 11 arranged pivot axis 6th be swiveled down - as in 1b shown - up the leg brace 4th with the free end protrudes vertically downwards.

In this vertical support position, the loading platform 102b1 get up like in 1c shown.

In this elevated position, the cargo bike 100 under the elevated interchangeable container 1 extended or retracted under them, as in 1d shown.
