Description

Description

The present invention relates to a transport box support system for an electric scooter, a coupling device for an electric scooter and an electric scooter.

For example, transport containers for transporting loads are known from the state of the art, which can be picked up and transported by trucks, trains and ships. The aim is always to enable safe transport while at the same time enabling quick changes between different transport vehicles. Furthermore, various electric scooters are known from the state of the art, which are suitable for transporting people and/or cargo due to their configuration. Conventional electric scooters therefore usually cover a specific transport scenario and therefore usually have specific means of transport to transport cargo or people. An example cargo scooter with a charging box is known from PCT/EP2019/086679.

It is therefore an object of the present invention to provide a transport box support system for an electric scooter, which enables safe and efficient coupling with an electric scooter, in particular with a coupling device of an electric scooter.

Furthermore, it is an object of the present invention to provide a coupling device for an electric scooter and an electric scooter which enable safe and efficient coupling with a transport box support system, in particular with a transport box support system that supports a transport box.

The above-described object is solved by the subject matter of the independent claims, preferred embodiments are the subject matter of the dependent claims.

One aspect of the invention relates to a transport box support system for an electric scooter, the transport box support system comprising:

- a frame for arranging a transport box on it;

- a front support system with at least one support element, wherein the front support system is pivotally arranged on a front portion of the frame such that the front support system is configured to selectively assume a support position or a transport position;

- a rear support system with at least one support element, wherein the rear support system is pivotally arranged on a rear portion of the frame such that the rear support system is configured to selectively assume a support position or a transport position;

- wherein the front and rear support systems are arranged at a distance from one another in a longitudinal direction of the frame;

- wherein the front support system has a first pivot portion;

- wherein the rear support system has a second pivot section; and

- wherein the first pivoting portion is configured to be actuated before the second pivoting portion when the transport box support system is coupled to the electric scooter, so that the at least one support element of the front support system is pivoted into the transport position before the at least one support element of the rear support system is pivoted into the transport position.

The present transport box support system advantageously enables a safe and efficient step-by-step coupling with the electric scooter, in that when coupling of the transport box support system with an electric scooter, the first pivoting section is configured to be actuated before the second pivoting section, so that the at least one support element of the front support system is pivoted into the transport position before the at least one support element of the rear support system is pivoted into the transport position. In this case, even if the front support system is already at least partially pivoted or in the transport position, the rear support system can advantageously still be in the support position and support the coupling with the electric scooter. In other words, the present transport box support system, which is loaded in particular with a transport box, can advantageously support the transport box during coupling with the electric scooter by means of the rear support system in that the at least one support element of the rear support system is only pivoted into the transport position after the at least one support element of the front support system.

In addition, the present transport box support system further makes it possible to provide a safe step-by-step transition from a state not coupled to the electric scooter to a state coupled to the electric scooter, wherein the load emanating from the possibly loaded transport box is borne substantially or entirely by the transport box support system before coupling, is borne partially by the transport box support system and partially by the electric scooter during coupling, and is borne substantially or entirely by the electric scooter after coupling to the electric scooter. The associated step-by-step load transition, ensured by the transport box support system, advantageously makes it possible to configure the coupling in a particularly safe and efficient manner.

In particular, by means of the present transport box support system and the coupling configured therewith with the electric scooter, the need for additional coupling aids, in addition to the transport box support system and the electric scooter, which has a coupling device for receiving the transport box support system or for connecting to the transport box support system, can be reduced or eliminated. In particular, the transport box support system can be configured to be connected to the coupling device of the electric scooter together with the transport box that may be arranged thereon and possibly fully or partially loaded or to be received by the coupling device of the electric scooter. In this way, in addition to reducing coupling aids, the transport box support system can advantageously provide a storage system for supporting a transport box at a storage location, such as in a warehouse or on a storage area. The storage system provided integrally by the transport box support system is advantageously transported along with the electric scooter by coupling it with the electric scooter, so that the provision of supports at a storage location can advantageously be dispensed with. In other words, the present transport box support system can integrally provide a storage system, in particular for the elevated storage of a transport box, with a coupling aid for safe and efficient coupling to a vehicle, in particular an electric scooter.

In exemplary embodiments, the front support system can be resiliently pivotably arranged on the frame of the transport box support system and/or the rear support system can be resiliently pivotably arranged on the frame of the transport box support system.

Preferably, the front support system can be arranged pre-tensioned on the frame of the transport box support system in the support position and/or the rear support system can be arranged pre-tensioned on the frame of the transport box support system in the support position.

When coupling the transport box support system to the electric scooter, the pre-tension of the respective front and/or rear support system in the support position can be overcome in order to cause the respective support system to pivot from the support position into the transport position.

The transport box support system can be used by the front support system and the rear Support system, in particular by means of the resilient or pre-stressed arrangement, advantageously provide a passive support system, wherein a transition from support by means of the support systems to transport by means of the electric scooter and vice versa, by means of a corresponding coupling or decoupling, is achieved in a passive manner without a user having to carry out additional active operations.

In exemplary embodiments, one of the transport box support system and the coupling device of the electric scooter can have a securing device in order to secure the transport box support system to the electric scooter after coupling, in particular to secure it in a roadworthy manner.

In preferred embodiments, the securing device can passively engage when coupling the transport box support system to the coupling device of the electric scooter. In alternative embodiments, the securing device can require an actively actuated engagement or locking by a user in order to secure the transport box support system to the electric scooter, in particular to the coupling device of the electric scooter.

In exemplary embodiments, the coupling can preferably be effected by means of a relative movement between the electric scooter and the transport box support system, in particular by means of a relative movement parallel to the direction of travel of the electric scooter, particularly preferably parallel to the forward or backward direction of travel of the electric scooter.

In exemplary embodiments, the transport box support system and the electric scooter can be coupled by moving the electric scooter forward in the direction of travel, in particular substantially horizontally towards the transport box support system. In preferred embodiments, the transport box support system and the electric scooter can be coupled by moving the electric scooter forward in the direction of travel, facing the front area of the transport box support system. When coupling the transport box support system to the electric scooter, in particular to the coupling device of the electric scooter, the transport box support system can face the electric scooter, in particular the coupling device of the electric scooter, in particular with the front support system. In other words, when coupling the transport box support system to the electric scooter, the front support system preferably faces the electric scooter.

In exemplary embodiments, the transport box support system can have a coupling direction-related coding. The coupling direction-related coding of the transport box support system can preferably be configured to allow coupling of the transport box support system to the electric scooter, in particular the coupling device of the electric scooter, only in one essential direction. In particular, the coupling direction-related coding of the transport box support system can be configured to prevent pivoting of the front support system and/or the rear support system out of the support position unless coupling takes place according to the coupling direction-related coding.

In exemplary embodiments, the coupling direction-related coding can be a section closed along a circumference of the frame, for example a frame casing section arranged on the frame of the transport box support system, which extends essentially in the height direction along the circumference of the frame. The closed section on the frame can, with the exception of coding openings, in particular be arranged completely circumferentially on the frame, or in particular be arranged at least in the rear region of the frame. The closed section or the frame casing section is in particular configured to prevent coupling with the coupling device of the electric scooter. An open section can be arranged or formed essentially in the longitudinal direction of the frame or the transport box support system opposite the closed section, which is configured to prevent coupling in particular with the The coupling device of the electric scooter is not to be prevented, but to be enabled or permitted. The open section can be arranged or formed in particular in a front region of the frame, i.e. arranged or formed in a region of the transport box support system facing the front support system. Furthermore, the open section can be arranged or formed in particular as a coding or coding opening on the frame casing section. The combination of closed section and open section or the frame casing section provided with openings form, for example, an advantageous coupling direction-related coding for the transport box support system.

In the following, various terms are used repeatedly, the understanding of which is intended to be facilitated by the following definitions.

Electric scooter: In the present case, an electric scooter is understood to mean in particular a scooter-like vehicle or vehicle which has at least one front wheel, preferably two front wheels, and at least one rear wheel, wherein the electric scooter is suitable for transporting loads, for example in the form of other people, such as passengers, packages, food or other goods. Furthermore, the electric scooter has in particular at least one electric motor as a drive. Nevertheless, the present aspects and embodiments are not limited to an electric scooter which explicitly has to have at least one electric motor as a drive. Rather, the electric scooter can instead also comprise or be a cargo scooter with an internal combustion engine or a fuel cell as a drive. The electric scooter, which has at least one electric motor, is, however, particularly advantageous in that it can be charged in a simple manner, for example at a socket, or can be made ready for operation by quickly changing the battery. Furthermore, the electric scooter, which has an electric motor as a drive, does not produce any exhaust gases when driving, and the electric scooter is therefore particularly suitable for operation and for covering transport routes in closed buildings, such as office spaces or residential areas. If the above and further reference is made to the “cargo scooter” or If the term “scooter” is used without any further reference to the drive, the term “electric scooter” should be used.

Longitudinal direction: The longitudinal direction describes a direction which essentially corresponds to the direction of movement of the electric scooter when driving straight forward. The longitudinal direction can also essentially correspond to a direction of the electric scooter from back to front. Furthermore, the longitudinal direction can essentially correspond to a direction of the transport box support system from a front area of the transport box support system, for example the front support system, to a rear area of the transport box support system, for example the rear support system. The forward and backward directions of travel are in particular approximately parallel to the longitudinal direction of the electric scooter, and preferably approximately parallel to the longitudinal direction of the transport box support system. The forward direction of travel can correspond to the longitudinal direction of the electric scooter and/or the longitudinal direction of the transport box support system, and the backward direction of travel can be parallel and opposite to the respective longitudinal direction.

Height direction: The height direction is generally perpendicular to the longitudinal direction and essentially corresponds to a normal on an imaginary surface on which the transport box support system stands, particularly in the support position, and/or on which the electric scooter can be moved.

Width direction: The width direction is generally essentially perpendicular to the length direction and the height direction. The width direction can also be referred to as the transverse direction or the transverse direction.

The height direction, the width direction and the length direction can form a coordinate system, in particular a right-hand system. The directions mentioned do not have a particular origin in the transport box support system and/or the electric scooter, but rather relate the elements or parts designated by them to one another. If a direction or an angle is indicated with the addition "substantially" or "approximately", this addition means or is to be understood in particular as a deviation from the direction or angle in question in the range from 0° to 5°.

If a spatial measure, a spatial ratio or any other ratio is described with the addition "substantially" or "approximately", this addition means or is to be understood in particular as a deviation from the measure or ratio in question in the range of 0% to 10%.

Support element: The support element is usually highlighted in connection with the front support system and/or the rear support system. The support element represents an element that is configured to support the frame of the transport box support system in the support position, in particular against a surface such as a floor. The support element of the front and/or rear support system can, for example, have an elongated shape. If the respective support system is in the support position, the support element of the respective support system can, in particular, extend essentially in the vertical direction. The support element can, for example, be designed as a leg, two-legged, three-legged, as an open or closed frame, in particular an essentially rectangular frame.

In exemplary embodiments, the at least one support element can have a rotary element or rolling element at its distal end, in other words at its end facing away from the frame, in other words at its end facing the ground in the support position, in particular one or more rollers, in particular to facilitate transport of the transport box support system in the support position. In preferred embodiments, at least one, in particular exactly one, of the front support system and the rear support system has at least one support element which has a rotary element or rolling element at its distal end. This can advantageously ensure that the Transport box support system in the support position, while by lifting the at least one support element of the front or rear support system, which does not have a rotating element or rolling element, transport of the transport box support system is made possible in a particularly simple manner.

Support position: The support position is used here essentially to designate a position or position of the front and/or rear support system, in particular to designate a position or position of one or more support elements of the front and/or rear support system. The support position describes a position or position, wherein the at least one support element of the respective support system supports the frame relative to a base, in particular a floor. The at least one support element can therefore be arranged in the support position in particular essentially parallel to the height direction, in which case in particular an arrangement of the at least one support element inclined relative to the height direction, which is still suitable for supporting the frame of the transport box support system relative to a base, is to be included. If the transport box support system is referred to here as being in the support position, this is to be understood as meaning that both the front and the rear support system, in particular their respective at least one support element, are arranged or positioned in the support position.

Transport position: The transport position is used here essentially to designate a position or position of the front and/or rear support system, in particular to designate a position or position of one or more support elements of the front and/or rear support system. The transport position describes a position or position, wherein the at least one support element of the respective support system is pivoted relative to the support position and does not support the frame relative to a surface, in particular a floor. The transport position can in particular be a position or position which the at least one support element of the respective support system assumes when the transport box support system is connected to the electric scooter, in particular the coupling device of the electric scooter, is coupled, in particular at least partially coupled. In the transport position, in exemplary embodiments, the at least one support element can be arranged in particular substantially perpendicular to the height direction, for example arranged substantially parallel to the longitudinal direction or width direction, or arranged substantially parallel to a surface spanned by the longitudinal direction and width direction, in particular arranged substantially horizontally. If the transport box support system is referred to here as being in the transport position, this is to be understood to mean that both the front and the rear support system, in particular their respective at least one support element, are arranged or positioned in the transport position.

In preferred embodiments of the transport box support system, the front support system and the rear support system can be configured to be pivotable relative to one another, in particular can be configured to be pivotable exclusively relative to one another, and/or in particular can be configured to be pivotable relative to one another such that the at least one support element of the front support system and the at least one support element of the rear support system are each arranged within the frame in the transport position.

The configuration of the front support system and the rear support system that can be pivoted relative to one another enables an advantageous combination in which the front support system and the rear support system provide secure support in the support position and at the same time assume a space-saving position in the transport position. As a result, when the transport box support system is coupled to the electric scooter, the transport box can advantageously be positioned low on the electric scooter, which increases the driving stability of the electric scooter during transport of the transport box on the electric scooter.

In exemplary embodiments, the front support system and the rear support system can be configured to pivot relative to each other in such a way that they can be pivoted in different directions, in particular in opposite directions, in other words can be pivoted towards each other. Thus, the front support system can be pivoted in particular backwards during a transition from the support position to the transport position, and the rear support system can be pivoted in particular forwards during a transition from the support position to the transport position.

This advantageously helps to increase the distance between the support elements of the front and rear support systems in the support position, thereby ensuring stable support while ensuring a space-saving arrangement in the transport position.

In exemplary embodiments, the at least one support element of the front support system and the at least one support element of the rear support system can be arranged substantially parallel to one another in the respective transport position, and/or arranged substantially in the same spanning plane, for example substantially in a plane which is spanned by the longitudinal direction and the width direction of the transport box support system or the electric scooter. This advantageously enables a flat arrangement of the transport box support system on the electric scooter, which advantageously increases driving stability during transport.

Furthermore, in exemplary embodiments, the support elements can be pivotable in particular substantially about an axis which is parallel to the width direction of the transport box support system.

In preferred embodiments of the transport box support system, the transport box support system can further comprise a front locking device which is configured to releasably lock the front support system in the support position, in particular to releasably lock the first pivot section; and/or comprise a rear locking device which is configured to releasably lock the rear support system in the support position, in particular to second pivoting section to be releasably locked.

The releasable locking of the front support system and/or the rear support system in the support position advantageously makes it possible to ensure the respective support position, so that unintentional tipping of the transport box is avoided, for example while the transport box is being stored on the transport box support system and/or while it is being coupled to the electric scooter.

In exemplary embodiments, the front locking device and the rear locking device may be configured such that when coupling to the electric scooter, the front locking device is released before the rear locking device is released.

This can advantageously ensure that the rear support system is or remains arranged in the support position while the transport box support system is coupled to the electric scooter, in particular to the coupling device of the electric scooter.

The front locking device can in particular form a positive locking mechanism for releasably locking the front support system in the support position, in particular for releasably locking the first pivoting section of the front support system in order to fix the front support system in the support position. In other words, the front locking device can form a positive locking mechanism, in particular with the first pivoting section of the front support system, which releasably locks the front support system in the support position.

Furthermore, the front locking device can be arranged on the frame in a deflectable or rotatable manner, preferably resiliently deflectable or rotatable manner. The front locking device can be arranged, for example, by means of a swivel joint or hinge, in particular by means of a sliding bearing, on the frame. In exemplary embodiments, the front locking device can be arranged on the frame in a resiliently deflectable or rotatable manner by means of a tension spring or torsion spring, which preloads the front locking device into a position that locks the front support system, in particular into a position that positively locks the front support system.

Furthermore, in exemplary embodiments, the front locking device can have a groove which is configured to positively engage around the front support system, and in particular the first pivot section of the front support system in the support position. For this purpose, the front locking device can have, for example, a folding part or bent part, in particular a folded or bent sheet, in particular a sheet that is folded or bent in sections. As a result, the front locking device can be manufactured in a simple manner, can be provided with resilient properties in a simple manner, can be actuated in a simple manner by means of an actuating section of the coupling device, and can be repaired in a simple manner in the event of damage.

In exemplary embodiments, the rear locking device can be designed separately from the front locking device. This advantageously ensures a step-by-step or sequential actuation of the front and rear locking devices.

In alternative embodiments, the rear locking device can be formed integrally with the front locking device. The integral front and rear locking device can be configured, for example, to define a first relative unlocking position of the coupling device relative to the transport box support system, in which the coupling device is configured to release only the front locking device, and a second relative unlocking position of the coupling device relative to the To define a transport box support system in which the coupling device is configured to release the front and rear locking devices. This advantageously enables a simple step-by-step release of the locks of the support systems.

The rear locking device can in particular form a positive locking mechanism for releasably locking the rear support system in the support position, in particular for releasably locking the second pivoting section of the rear support system in order to fix the rear support system in the support position. In other words, the rear locking device can form a positive locking mechanism, in particular with the second pivoting section of the rear support system, which releasably locks the rear support system in the support position.

Furthermore, the rear locking device can be arranged on the frame in a deflectable or rotatable manner, preferably in a resiliently deflectable or rotatable manner. The rear locking device can be mounted on the frame, for example, by means of a rotary joint or hinge, in particular by means of a plain bearing. In exemplary embodiments, the rear locking device can be arranged on the frame in a resiliently deflectable or rotatable manner by means of a tension spring or torsion spring, which preloads the rear locking device in a position that locks the rear support system, in particular in a position that positively locks the rear support system.

Furthermore, in exemplary embodiments, the rear locking device can have a groove which is configured to positively engage the rear support system and in particular the second pivot section of the rear support system in the support position. For this purpose, the rear locking device can have, for example, a folding part or a bent part, in particular a folded or bent sheet, in particular a sheet that is folded or bent in sections. This allows the rear locking device to be easily manufactured, easily provided with resilient properties, easily operated and, in case of damage, easily repaired.

In further exemplary embodiments, the rear locking device can be coupled to a rear release device, in particular while maintaining a predefined coupling distance. The predefined coupling distance can be predefined, for example, by means of a release coupling element, such as by means of a coupling rod, coupling beam, or coupling tube. The release coupling element can be connected, in particular, at its distal ends by means of a joint, in particular by means of an eyelet. The rear release device can be arranged in front of the rear locking device, in particular in the longitudinal direction of the transport box support system. In other words, the rear release device can be arranged at a distance from the rear locking device in the longitudinal direction, facing the front support system. In preferred embodiments, the rear release device is arranged on the frame in a deflectable, in particular rotatable or rotatable manner.

In further preferred embodiments, the rear locking device is coupled by means of a release coupling element to a deflectably mounted rear release device, such that a deflection, in particular a rotation or rotation of the rear release device by means of the release coupling element causes a deflection of the rear locking device and releases the releasable locking of the rear support system.

The rear release device can advantageously define a point in time and a relative position between the transport box support system and the coupling device of the electric scooter for releasing the locking of the rear support system when coupling the transport box support system with the coupling device of the electric scooter. This allows the coupling device to be advantageously made short, in particular in the longitudinal direction, whereby the electric scooter can be advantageously configured to save space, especially if there is no transport box support system and transport box attached to it.

In preferred embodiments of the transport box support system, the front locking device can be configured to positively fix the first pivot section of the front support system in the support position, and/or the rear locking device can be configured to positively fix the second pivot section of the rear support system in the support position.

By positively fixing the front support system and/or the rear support system, a passive fixing or locking of the respective support systems in the support position can advantageously be provided, which at the same time enables a passive release or unlocking when coupling the transport box support system with the electric scooter, in particular with the coupling device of the electric scooter.

In preferred embodiments of the transport box support system, the front locking device can have a release portion, wherein the release portion is inclined with respect to a relative direction of movement of the transport box support system for coupling the transport box support system to the electric scooter.

The release section is preferably arranged rigidly, in particular in a rotationally fixed manner, on the front locking device. This allows a deflection of the release section during coupling to cause a deflection, in particular tilting, turning or twisting, of the front locking device corresponding to the deflection of the release section, in particular into an unlocked position.

By inclining the release section of the front locking device, the front locking device can be easily operated and in particular deflected. For example, the release section can be an actuating projection of the coupling device can be actuated or deflected, wherein the inclination of the release section with respect to the relative direction of movement during coupling, when the electric scooter is moved in a coupling direction, advantageously causes an increasing deflection of the release section, depending on the relative position of the transport box support system to the coupling device during coupling.

In preferred embodiments of the transport box support system, the front locking device can be resiliently rotatably mounted, and/or the rear locking device can be resiliently rotatably mounted.

The resiliently rotatable bearing of the front and/or rear locking device advantageously makes it possible to provide a passive and reusable locking device for the respective support system, which in turn enables an advantageously safe and time-efficient coupling and decoupling.

In preferred embodiments of the transport box support system, the transport box support system can be configured to be coupled to the electric scooter by means of a movement of the transport box support system relative to the electric scooter, wherein the movement of the transport box support system relative to the electric scooter occurs in a direction which is substantially perpendicular to an extension of the at least one support element of the front support system in the support position.

In other words, in preferred embodiments, the transport box support system can be configured to be coupled to the electric scooter by means of a movement of the transport box support system relative to the electric scooter, wherein the movement of the transport box support system relative to the electric scooter occurs in a direction which is substantially parallel to the longitudinal direction of the transport box support system, and in further other words which is substantially parallel to the direction of travel of the electric scooter. By coupling the device essentially perpendicular to the vertical direction or essentially parallel to the longitudinal direction or direction of travel, it is advantageous to enable coupling that is economical in terms of energy and time. In particular, a comparatively complex lifting of the transport box support system and/or the transport box using third-party funds for coupling the transport box support system and the electric scooter can be avoided.

In preferred embodiments of the transport box support system, the first pivoting section can be configured to be actuated when coupled to the electric scooter only when a part of the transport box support system rests at least partially on a coupling device of the electric scooter.

Additionally or alternatively, in preferred embodiments of the transport box support system, the release section can be configured to be activated when coupled to the electric scooter only when a part of the transport box support system rests at least partially on a coupling device of the electric scooter.

By configuring the first pivoting section and/or release section to only be actuated when the transport box support system is partially resting on the coupling device of the electric scooter, it is advantageously possible to ensure that the transport box support system, in particular the transport box of the transport box support system, is supported during coupling with the electric scooter. This means that even if the front support system is released or unlocked from the support position, or is pivoted during coupling, the transport box support system and in particular its transport box are already supported by the electric scooter and the rear support system.

This in turn ensures that the transport box support system and the electric scooter are coupled both safely and efficiently. In exemplary embodiments, the transport box support system can have a frame lifting section that is configured to interact with a complementary lifting section of the coupling device of the electric scooter, in particular to interact in such a way that the transport box support system is raised with increasing relative movement between the transport box support system and the electric scooter in a coupling direction. By lifting the transport box support system during coupling, the load on the front support system in particular is preferably relieved, for example by raising the transport box support system in such a way that the at least one support element of the front support system no longer supports the transport box support system against a ground, i.e. the at least one support element of the front support system leaves the ground.

For example, the frame lifting section and the complementary lifting section can form a coupling level that increases at least in sections, in particular with regard to the height direction of the transport box support system and the electric scooter with coupling device.

Raising the transport box support system, in particular the frame of the transport box support system, when coupling the transport box support system to the coupling device of the electric scooter also advantageously makes it easier to pivot the front support system out of the support position and thus to carry out the coupling process in a particularly energy- and time-efficient manner.

In preferred embodiments of the transport box support system, the front support system can be mounted in a resiliently rotatable manner and/or the rear support system can be mounted in a resiliently rotatable manner.

In other words, in preferred embodiments, the front support system and/or the rear support system can be mounted in a resiliently pivotable manner, in particular can be mounted in a resiliently pivotable manner about an axis extending substantially in the width direction or transversely. In particular, the front support system and/or the rear support system can be mounted so as to be elastically resilient and rotatable or pivotable.

In exemplary embodiments, the front support system and/or the rear support system can each be arranged rotatably on the frame by means of a hinge or swivel joint, in particular by means of a plain bearing. The use of a plain bearing enables in particular a low-maintenance rotatable bearing over a predetermined service life or period of use of the transport box support system.

Furthermore, in exemplary embodiments, the front support system and/or the rear support system can be connected to the frame by means of a resilient element, in particular an elastic element, in particular in order to pre-tension the respective support system into the support position or the transport position. For example, the front support system and/or the rear support system can be connected to the frame by means of a spring, in particular a tension spring or torsion spring, an elastic band, or in another resilient manner, in particular elastically resilient.

The resilient arrangement of a support system facilitates the reversible arrangement of the support system in the support position and transport position, and thus promotes reusability and, for example, especially efficiency when coupling and uncoupling.

The pre-tensioned arrangement of a support system further enables a particularly passive transition between the support position and the transport position of a support system, so that the efficiency when coupling and uncoupling between the electric scooter with coupling device and the transport box support system is advantageously improved.

A further aspect of the invention relates to a coupling device for a Electric scooter, in particular for coupling with a transport box support system, according to the preceding aspect and according to its preferred, exemplary and alternative embodiments relating to a transport box support system, wherein the coupling device comprises:

- a first coupling projection which extends substantially in a direction of travel of the electric scooter,

- wherein the first coupling projection has a lifting portion which is inclined relative to the direction of travel of the electric scooter; and

- an operating projection extending substantially in a direction of travel of the electric scooter;

- wherein the operating projection has an operating portion which is inclined with respect to the direction of travel of the electric scooter;

- wherein the first coupling projection is configured to lift the transport box support system when the transport box support system is coupled to the coupling device of the electric scooter before the actuating section unlocks a front locking device for releasably locking a front support system in a position supporting the transport box support system.

Advantageously, the present coupling device enables the front support system of the transport box support system to be coupled to remain in the support position until the transport box support system, and in particular the front support system of the transport box support system, is raised, so that sufficient support of the transport box support system is always ensured. At the same time, in the event of faulty coupling, where the lifting does not work correctly, for example, the transport box support system can continue to rest safely on the front and rear support system.

In preferred embodiments of the coupling device, the coupling device further comprises:

- at least one second coupling projection which extends substantially in a direction of travel of the electric scooter and in a width direction of the Electric scooter is arranged at a distance from the first coupling projection,

- wherein one of the first coupling projection and the at least one second coupling projection is configured to cause the front support system to pivot from the unlocked support position into a transport position when the transport box support system is coupled to the coupling device.

The plurality of coupling projections can advantageously provide a secure coupling of the transport box support system to the coupling device, wherein in particular a step-by-step load transfer from the support systems of the transport box support system to the coupling device, and in particular to the electric scooter on which the coupling device is preferably arranged, is ensured.

Since the coupling device is configured to pivot the front support system only when the front support system is unlocked, a particularly safe step-by-step coupling can still be enabled.

Another aspect of the invention relates to an electric scooter comprising:

-a coupling device for coupling to a transport box support system, wherein the coupling device and the transport box support system are each a coupling device and a transport box support system according to the respective preceding aspects, as well as according to their preferred, exemplary and alternative embodiments.

Figure 1 shows a perspective view of a transport box support system 100 with an electric scooter 5 and coupling device 10, according to an embodiment of the present invention. In Fig. 1, the transport box support system 100 and the electric scooter 5, in particular the coupling device 10, which is arranged on the electric scooter 5, are shown in a non-coupled state, i.e. in a decoupled state. The electric scooter 5 and the transport box support system 100 are shown in Fig. 1 as an example on a sketched surface 1. The surface 1 can be any surface 1 on which in particular the transport box support system 100 can be placed and the electric scooter 5 can be operated by pushing or driving.

As can be seen in Fig. 1, the electric scooter 5 has the coupling device 10 on its front side, in particular on a front side in the longitudinal direction L. In alternative embodiments to that shown in Fig. 1, the coupling device 10 can be arranged on a rear side, in particular on a rear side of the electric scooter 5 in the longitudinal direction L. The coupling device 10 can be detachably fixed to the electric scooter 5 or permanently fixed to the electric scooter 5, for example by means of a screw connection, a snap connection, a welded connection, or another connection.

As shown in Fig. 1, the transport box support system 100 has in particular a frame 110. In particular, a front support system 120 with at least one support element 122 and a rear support system 140 with at least one support element 142 are arranged on the frame 110. As shown in Fig. 1, the front support system 120 is arranged in the longitudinal direction L when coupled to the electric scooter 5, in particular when coupled to the coupling device 10 of the electric scooter 5, facing the electric scooter 5 or the coupling device 10. especially when, as shown in Fig. 1, the transport box support system 100 and the coupling device 10 are in an uncoupled state. The rear support system 140 is arranged at a distance from the front support system 120 in the longitudinal direction L.

As further shown in Fig. 1, the frame 110 preferably has a coding 112 on an end facing the coupling device 10 in the longitudinal direction L during coupling. The coding 112 can in particular be formed by recesses which are configured to enable or permit coupling to the coupling device 10 in only one direction. The frame 110 preferably has no recesses corresponding to the coding 112 on its side opposite the coding 112 in the longitudinal direction L, and thereby prevents coupling to a coupling device 10 from a side of the frame 110 opposite the coding 112. In other words, the coding 112 configures the transport box support system 100 to be able to be coupled in a single direction, in particular to be able to be coupled exclusively essentially in the longitudinal direction L. The frame 110 preferably prevents coupling in a direction parallel opposite to the longitudinal direction L.

As a result, the transport box support system 100 can advantageously be provided or designed with a direction-specific coupling mechanism, ensuring compliance with a predetermined sequence when coupling the transport box support system 100 to the coupling device 10.

In preferred embodiments and as shown in Fig. 1, the frame 110 has an opening or recess as a coding 112 for each coupling projection 60, 70, 80 of the coupling device 10, as shown in particular in the other figures.

As shown in Fig. 1, the frame 110 may in particular have a frame shell portion 111 which extends along a circumference of the frame 110 similar to an apron or a shell substantially in Height direction H. The coding 112 can in particular comprise one or more openings in the frame casing section 111, preferably one opening per coupling projection 60, 70, 80 of the coupling device 10, with which the transport box support system 100 can be coupled.

As shown in Fig. 1, a roller or a wheel, preferably a lockable roller or a lockable wheel, can be arranged at a distal end of a support element 122, 142. The locking of a roller or a wheel can be provided in particular by means of a parking brake, wherein the parking brake can preferably be activated and deactivated by a user in order to facilitate coupling of the transport box support system 100 to the coupling device 10.

In further exemplary embodiments, only the at least one support element 122, 142 of the front support system 120 or the rear support system 140 can have a roller or a wheel. As a result, the transport box support system 100 can stand in a fixed position on the base 1, in particular when the front support system 120 and the rear support system 140 are in a support position. Furthermore, when the transport box support system 100 is lifted on a side that is opposite the at least one support element 122, 142 with roller or wheel, it can be easily shifted or moved, in particular if no locking is activated.

As can be seen from Fig. 1, the transport box support system 100 can be coupled to the electric scooter 5, in particular to the coupling device 10, which is arranged on the electric scooter 5, by moving the electric scooter 5 forwards, in particular substantially in the longitudinal direction L. In alternative embodiments, and in particular depending on the arrangement of the coupling projections 60, 70, 80 of the coupling device 10 and the design of the frame 110, the transport box support system 100 and the coupling device 10 can also be coupled in a different direction, in particular can be coupled exclusively. Fig. 2 shows a perspective view of a transport box support system 100 and a coupling device 10, according to an embodiment of the present invention, from below. Fig. 2 shows the transport box support system 100 and the coupling device 10 in particular in a decoupled state, whereby, for the sake of clarity, as in the other figures, a representation of the electric scooter 5 is omitted. However, the coupling device 10 is always to be assumed to be arranged on the electric scooter 5 for coupling with the transport box support system 100, even if the electric scooter 5 is not shown. This also applies to the other following figures.

As shown in Fig. 2, the coupling device 10 has at least one coupling projection 60, 70, 80 which extends forward substantially in the longitudinal direction L. In other words, the at least one coupling projection 60, 70, 80 is particularly configured to extend towards the transport box support system 100 when coupled to the transport box support system 100. In Fig. 2, the coupling device 10 is shown with three coupling projections 60, 70, 80 by way of example. In alternative embodiments, the coupling device 10 can have only two of the three coupling projections 60, 70, 80. The coupling projections 60, 70, 80 are particularly configured to support the transport box support system 100 when coupled.

As further shown in Fig. 2, the coupling device 10 has in particular an actuating projection 50, wherein the actuating projection 50 is preferably designed separately from the at least one coupling projection 60, 70, 80. In addition, the actuating projection 50 is designed in particular to protrude substantially in the longitudinal direction L from the coupling device 10. As can be seen in Fig. 2, the actuating projection 50 is provided at its front end with a slope as an actuating section 52, so that when coupled substantially in the longitudinal direction L, it causes or is configured to cause an actuation substantially in the height direction H. In particular, the actuating section 52 of the actuating projection 50 has with increasing extension in the longitudinal direction L a decreasing height in the height direction H. As a result, the actuating projection 50 is preferably configured to have a levering or pressing effect during a movement substantially in the longitudinal direction L upwards, that is to say in particular to have a levering or pressing effect substantially in the height direction H upwards.

As further shown in Fig. 2, the coupling device 10 can in particular be designed in the manner of a rail. Furthermore, the coupling device 10 can in particular extend with a branch, in particular such that the coupling device 10 branches towards the one or more coupling projections 60, 70, 80, in particular at a front end of the coupling device 10 in the longitudinal direction L.

As can be seen in Fig. 2, the coupling device 10 can have, at least in sections, essentially a T-profile or a double T-profile. As shown in Fig. 2, the profile corresponds essentially to a cross section of the coupling device 10, in particular a cross section with a cutting plane that extends essentially in the height direction H and the width direction B.

As can be seen in Fig. 2 by way of example using the third coupling projection 80, the coupling projections 60, 70, 80 can each have, at least in sections, essentially a T-profile or a double T-profile. As shown in Fig. 2, the profile corresponds essentially to a cross section of the coupling device 10, in particular a cross section with a cutting plane that extends essentially in the height direction H and the width direction B.

The coupling device 10 and the coupling projections 60, 70, 80, provided they have a T-profile or double T-profile, are advantageously rigid and suitable for supporting heavy loads, in particular the possibly loaded loading box 105. Furthermore, the T-profile and the double T-profile advantageously make it possible to provide a guide for the coupling device 10 and for the coupling projections 60, 70, 80, wherein the parts provided with the respective profile at least are guided in sections by one or more coupling guides 116 which are arranged on the frame 110, in particular are guided so as to form a positive connection with respect to the height direction H. The one or more coupling guides 116, as shown in Fig. 2, can in particular have a T-shaped groove or opening. The groove or opening of the respective coupling guide 116 is essentially T-shaped, in particular in a cross-section with a cutting plane which extends essentially in the height direction H and the width direction B. The coupling guides 116 advantageously ensure that a respectively guided coupling projection 60, 70, 80 is guided along an alignment, in particular is guided essentially in the longitudinal direction L.

By arranging the coupling guides 116, the coupling process of the transport box support system 100 with the coupling device 10 can advantageously be guided, so that complementary sections and elements of the transport box support system 100 and the coupling device 10 are guided precisely towards each other during coupling, and the precise actuation of the mechanisms described here is ensured during coupling and/or uncoupling of the transport box support system 100 and the coupling device 10.

As indicated in Fig. 2, the coupling device 10 can have a stop 12 at a rear end in the longitudinal direction L. The stop 12 can in particular be configured to limit a relative movement between the coupling device 10 and the transport box support system 100. The stop 12 can for example be configured to form a positive connection with one of the coupling guides 116 with respect to the longitudinal direction L. The stop 12 can for example be designed as a catch or clip. In alternative embodiments, the stop 12 can only be designed as an opening in order to fix the transport box support system 100 to the coupling device 10 with a securing element, such as a pin or split pin, in particular to fix it releasably. The stop 12 is therefore preferably configured to limit a relative position between the coupling device 10 and the transport box support system 100 in a coupled state, in particular to fix it detachably.

As can be seen in Fig. 2 with a view of the transport box support system 100, the transport box support system 100 has the front support system 120 and the rear support system 140, wherein the two support systems 120, 140 are arranged on the frame 110 of the transport box support system 100 essentially at a distance from one another in the longitudinal direction L. The front support system 120 is arranged on the frame 110 facing the coupling device 10 in particular in the longitudinal direction L during coupling. The rear support system is arranged on the frame 110 facing away from the coupling device 10 in particular in the longitudinal direction L during coupling.

As can be seen in Fig. 2, the front support system 120 has at least one support element 122, in particular two support elements 122. The rear support system 140 has at least one support element 142, in particular two support elements 142.

The support elements 122, 142 of the support systems 120, 140 are each shown in a support position in Fig. 2. The transport box support system 100 and the transport box 105, provided that the latter is arranged on the transport box support system 100 as shown in Fig. 2, rest on the respective support elements 122, 142. In other words, the support elements 122, 142 are configured in the support position to support the transport box support system 100 and any transport box 105 arranged thereon against the ground 1, as shown in particular in Fig. 1. The support elements 122, 142 of the support systems 120, 140 extend in the support position, as shown in Fig. 2, essentially in the height direction H. It is understood that the support elements can also have an inclined or diagonal extension, so that the support elements 122, 142 in the support position are in particular only configured to provide support for the frame 110 against a base 1 in the height direction H. An extension of the support elements 122, 142 essentially in the longitudinal direction L, in the support position, however, enables particularly space-saving support or storage by means of the transport box support system 100. As further shown in Fig. 2, the front support system 120 is fixed or locked in the support position, in particular releasably fixed or releasably locked, in particular by means of the front locking device 150. As shown in Fig. 2, in order to fix the front support system 120 in the support position, the locking device 150 can form a positive connection with the front support system 120, in particular form a positive connection with a first pivot section 130 of the front support system 120. In particular, the front locking device 150 can be configured to positively engage the front support system 120 on both sides in the support position with respect to the longitudinal direction L, and thereby advantageously lock it.

As shown in Fig. 2, the first pivot section 130 can, for example, extend substantially in the width direction B or at least partially extend in the width direction B, in particular extend in the width direction between two support elements 122 of the front support system 120. The front locking device 150 can form or have a groove 154 that positively surrounds the front support system 120, in particular a groove 154 that positively surrounds the first pivot section 130 of the front support system 120. In other words, the locking device 150 can in particular have a groove 154 that is configured to positively surround the front support system 120, in particular a section of the front support system 120 that extends substantially in the width direction B, in particular to positively surround it forming a positive connection with respect to the longitudinal direction L. The front support system 120 is releasably fixed or releasably locked in the support position by means of the front locking device 150. In particular, the front support system 120 is releasably locked in such a way that pivoting or swiveling of the front support system 120 from the support position into a transport position is prevented.

The transport position of the front support system 120 represents a position in which the front support system 120, in particular the at least one front support element 122 of the front support system 120, is pivoted relative to the support position. The front support system 120 and in particular the at least one support element 122 of the front support system 120 are preferably configured to assume the transport position when coupled to the coupling device 10, in particular by pivoting or swiveling. The front support system 120 can in particular be pivotable or swivelable essentially about an imaginary axis which extends essentially in the width direction B. In other words, the front support system 120 can in particular be arranged rotatably or swivelably on the frame 110, in particular rotatably or swivelably about an axis extending essentially in the width direction B, for example by means of a hinge, a sliding bearing or by means of another, in particular rotatable, bearing.

The front locking device 150 is arranged on the frame 110 in a resiliently foldable or rotatable manner, in particular in the position locking the front support system 120, pre-tensioned and arranged on the frame 110 in a resiliently foldable or rotatable manner, for example by means of a hinge, a sliding bearing, by means of another, in particular, rotatable bearing. Alternatively, the front locking device 150 can be fixed to the frame 110, wherein the front locking device 150 is configured in a resiliently foldable or resiliently deflectable manner, in particular by means of its contour or geometry, for example as a bent or folded sheet metal part. If the front locking device 150 is formed from a bent or folded sheet metal part, an additional bearing or hinge is advantageously unnecessary, so that the complexity of the transport box support system 100 can be advantageously reduced, and in particular passively acting means are provided for transferring the transport box support system 100 from the uncoupled state to the coupled state and back. However, as shown in Fig. 2, the front locking device 150 can, in preferred embodiments, be arranged on the frame 110 in a particularly pre-tensioned, resiliently foldable or rotatable manner and can have a contour that is bent or folded, in particular against the longitudinal direction L. In exemplary embodiments, the front locking device 150 is arranged on the frame 110 in a pre-tensioned manner, in particular by means of a resilient element, in particular in a position locking the front support system 120, pre-tensioned manner on the frame 110. The resilient element by means of which the front locking device 150 is arranged on the frame 110 in a pre-tensioned manner can in particular be a tension spring, a compression spring, a torsion spring, or the like, whereby the front locking device 150 is arranged on the frame 110 in a pre-tensioned manner, in particular elastically.

As shown in Fig. 2, the front support system 120 has in particular a front reinforcement element 124, which is configured to be encompassed by the front locking device 150 when the front support system 120 is in the support position, in particular to be encompassed in a form-fitting manner. The front reinforcement element 124 advantageously increases the longevity of the front support system 120 and thus of the transport box support system 100. The front reinforcement element 124 can in particular be or have a sectionally reinforcing wood or metal, a damping element such as a plastic or foam, or a damping and non-slip element such as an elastomer or a foam rubber. The front reinforcement element 124 can thus advantageously reinforce the front support system 120 in the position locked by means of the front locking device 150 and/or provide improved damping and/or non-slip properties.

As further shown in Fig. 2, the rear support system 140 is fixed or locked, in particular releasably fixed or releasably locked, in the support position, in particular by means of the rear locking device 170. As shown in Fig. 2, in order to fix the rear support system 140 in the support position, the rear locking device 170 can form a positive connection with the rear support system 140, in particular form a positive connection with a second pivot section 180 of the rear support system 140. As shown in Fig. 2, the second pivot section 180 can, for example, extend substantially in the width direction B or at least partially extend in the width direction B, in particular extend in the width direction between two support elements 142 of the rear support system 140. The rear locking device 170 can have a groove that positively surrounds the rear support system 140, in particular a groove that positively surrounds the second pivot section 180 of the rear support system 140. In other words, the rear locking device 170 can in particular have a groove that is configured to positively surround the rear support system 140, in particular a section of the rear support system 140 that extends substantially in the width direction B, in particular to form a positive connection with respect to the longitudinal direction L. The rear support system 140 is releasably fixed or releasably locked in the support position by means of the rear locking device 170. In particular, the rear support system 140 is releasably locked in such a way that pivoting or swiveling of the rear support system 140 from the support position into a transport position is prevented. In particular, the rear locking device 170 can be configured to positively engage the rear support system 140 on both sides in the support position with respect to the longitudinal direction L, and thereby advantageously lock it.

The transport position of the rear support system 140 represents a position in which the rear support system 140, in particular the at least one support element 142 of the rear support system 140, is pivoted relative to the support position. The rear support system 140 and in particular the at least one support element 142 of the rear support system 140 are preferably configured to assume the transport position when coupled to the coupling device 10, in particular by pivoting or swiveling. In this case, the rear support system 140 can be pivotable or swivelable in particular substantially about an imaginary axis which extends substantially in the width direction B. In other words, the rear support system 140 can be arranged in particular rotatable or swivelable on the frame 110, in particular rotatable or swivelable on an axis extending substantially in the width direction B. the frame 110, for example by means of a hinge, a plain bearing or by means of another, in particular rotatable, bearing.

The rear locking device 170 is arranged on the frame 110 in a resiliently foldable or rotatable manner, in particular in the position locking the rear support system 140, pre-tensioned and arranged on the frame 110 in a resiliently foldable or rotatable manner, for example by means of a hinge, a sliding bearing, or by means of another, in particular, rotatable bearing. Alternatively, the rear locking device 170 can be fixed to the frame 110, wherein the rear locking device 170 is configured in a resiliently foldable or resiliently deflectable manner, in particular by means of its contour or geometry, for example as a bent or folded sheet metal part. If the rear locking device 170 is formed from a bent or folded sheet metal part, an additional bearing or hinge is advantageously unnecessary, so that the complexity of the transport box support system 100 can be advantageously reduced, and in particular passively acting means are provided for transferring the transport box support system 100 from the uncoupled state to the coupled state and back. However, as shown in Fig. 2, the rear locking device 170 can, in preferred embodiments, be arranged on the frame 110 in a pre-tensioned, resiliently foldable or rotatable manner and can have a contour that is bent or folded, in particular against the longitudinal direction L.

In exemplary embodiments, the front locking device 150 is arranged on the frame 110 in a pre-tensioned manner, in particular by means of a resilient element, in particular in a position locking the front support system 120, pre-tensioned manner on the frame 110. The resilient element by means of which the front locking device 150 is arranged on the frame 110 in a pre-tensioned manner can in particular be a tension spring, a compression spring, a torsion spring, or the like, whereby the front locking device 150 is arranged on the frame 110 in a pre-tensioned manner, in particular elastically.

As shown in Fig. 2, the rear support system 140 in particular comprises a rear Reinforcing element 144 which is configured to be gripped by the rear locking device 170 when the rear support system 140 is in the support position, in particular to be gripped in a form-fitting manner. The rear reinforcing element 144 advantageously increases the longevity of the front support system 140 and thus of the transport box support system 100. The rear reinforcing element 144 can in particular be or comprise a sectionally reinforcing wood or metal, a damping element such as a plastic or foam, or a damping and non-slip element such as an elastomer or a foam rubber. The rear reinforcing element 144 can thus advantageously reinforce the rear support system 140 in the position locked by means of the rear locking device 170 and/or provide improved damping and/or non-slip properties.

As shown in Fig. 2, the rear locking device 170, which is particularly configured to releasably lock the rear support system 140 in the support position, is coupled or connected to a rear release device 172, in particular by means of a release coupling element 174. The release coupling element 174 is particularly configured to pass on a deflection of the rear release device 172 to the rear locking device 170, so that the rear release device 172 is configured by means of the release coupling element 174 to pass on a deflection to the rear locking device 170.

The rear release device 172 is arranged on the frame 110 in a deflectable, in particular rotatable, preferably resiliently rotatable manner. As shown in Fig. 2, the rear release device 172 is arranged on the frame in front of the rear support system in particular in the longitudinal direction L. In other words, the rear release device 172 is arranged in particular in the longitudinal direction L between the rear support system 140 and the front support system 120. The upstream arrangement of the rear release device 172 advantageously enables an unlocking or releasing actuation of the rear locking device 170 in front of the longitudinal direction L, so that the coupling device 10 can be configured to be comparatively short in the longitudinal direction L and in particular to save space. can.

As shown in Fig. 2, the rear release device 172 can be deflected, in particular rotatable, preferably resiliently rotatable, in particular about an imaginary axis which extends substantially in the height direction H. The resilient deflection can be provided, for example, by means of a spring, in particular a torsion spring, which is arranged between the frame 110 and the rear release device 172 and thereby resiliently connects the rear release device 172 to the frame 110. In addition, the rear release device 172 can be arranged resiliently, in particular by means of a resilient connection of the rear locking device 170 to the frame 110, for example by means of a spring.

The release coupling element 174 can in particular be a rigid element that is essentially unchangeable with respect to its elongated extension when the rear release device 172 is deflected, such as a rod or a tube, in particular a metallic rod or a metallic tube.

As further shown in Fig. 2, the rear support system 140 in particular has a second pivot portion 180 to cause pivoting or swiveling of the rear support system 140 upon deflection of the second pivot portion 180.

As shown in Fig. 2, the second pivot section 180, which is particularly configured to pivot the rear support system 140 from the support position into the transport position, is coupled or connected to a rear pivot actuating device 182, in particular coupled or connected by means of a pivot coupling element 184. The pivot coupling element 184 is particularly configured to pass on a deflection of the rear pivot actuating device 182 to the second pivot section 180, so that the rear pivot actuating device 182 is configured by means of the pivot coupling element 184 to pass on a deflection to the second pivot section 180. The rear pivot actuating device 182 is arranged on the frame 110 in a deflectable, in particular rotatable, preferably resiliently rotatable manner. As shown in Fig. 2, the rear pivot actuating device 182 is arranged on the frame 110 in particular upstream of the rear support system in the longitudinal direction L. In other words, the rear pivot actuating device 182 is arranged in particular in the longitudinal direction L between the rear support system 140 and the front support system 120. The upstream arrangement of the rear pivot actuating device 182 advantageously enables pivoting of the rear support system 140, so that the coupling device 10 can be configured to be comparatively short in the longitudinal direction L and in particular to save space.

As shown in Fig. 2, the rear pivot actuating device 182 can be deflected, in particular rotatable, preferably resiliently rotatable, in particular about an imaginary axis which extends substantially in the height direction H. The resilient deflection can be provided, for example, by means of a spring, in particular a torsion spring, which is arranged between the frame 110 and the rear pivot actuating device 182, and thereby resiliently connects the rear pivot actuating device 182 to the frame 110. In addition, the rear pivot actuating device 182 can be arranged resiliently, in particular by means of a resilient connection of the rear support system 140 to the frame 110, for example by means of a spring.

When the rear pivot actuating device 182 is deflected, the pivot coupling element 184 can in particular be a rigid element that is essentially unchangeable with respect to its elongated extension, such as a rod or a tube, in particular a metallic rod or a metallic tube.

Finally, as can also be seen in Fig. 2, the frame 110 of the transport box support system 100 is particularly configured to support the transport box 105, and in particular to carry the support systems 120, 140 in the support position. The transport box 105 represents an exemplary transport container and can be suitable for transporting or storing various transport goods, products or people. The transport container can therefore also have a different shape, such as the shape shown in the figures, which is tailored to the respective transport scenario. The transport box support system 100, in conjunction with the coupling device 10, represents an advantageous modular system for storing, transporting, as well as coupling and uncoupling a transport container.

In Figures 3 to 7, various states with regard to the coupling between the transport box support system 100 and the coupling device 10, as already shown in Figures 1 and 2, are shown in an exemplary semi-transparent 1 view from above, wherein the electric scooter 5 is not shown in each case for the sake of clarity.

Fig. 3 shows an example of a first state when coupling the transport box support system 100 with the coupling device 10.

As shown in Fig. 3, the support elements 122, 142 are each in the support position to support the frame 110 of the transport box support system 100. As shown by way of example in Fig. 3, the support elements 122, 142 are each preloaded in the support position by means of a spring, so that a minimum pivoting force must be applied in order to pivot the respective support systems 120, 140 with their support elements 122, 142 from the support position into the transport position. As can be seen in Fig. 3, the front and/or rear support system 120, 140 can be arranged on the frame 110 in particular in a resilient manner, preferably in an elastically resilient manner on the frame 110, for example by means of a spring, a band or other particularly elastic means, in particular by means of one or more tension springs, compression springs or torsion springs.

As further shown in Fig. 3, the front support system 120 is connected by means of the front

Locking device 150 is releasably locked, whereby the front Locking device 150 is preferably pre-tensioned in a position locking the front support system 120.

As further seen in Fig. 3, the rear support system 140 is releasably locked by means of the rear locking device 170, wherein the rear locking device 170 is preferably pre-tensioned in a position locking the rear support system 140.

In Fig. 3, the rear release device 172 and the rear pivot actuating device 182 are each shown in an undeflected position or position. The rear release device 172 and/or the rear pivot actuating device 182 can be pre-tensioned in an undeflected position or position. For this purpose, the rear release device 172 and/or the rear pivot actuating device 182 can be pre-tensioned, for example, by means of a spring, in particular a torsion spring, or can be pre-tensioned via the respective coupling element 174, 184 by a pre-tensioned rear locking device 170 and/or by a pre-tensioned second pivot section 180.

In Figures 3 to 7, cutting lines of the cutting planes A-A, B-B and C-C are shown as broken lines. These broken lines represent cutting lines along which the sectional representations in Figures 8a to 10c are explained. The cutting planes A-A, B-B and C-C in Figures 3 to 7, shown by means of the broken cutting lines A-A, B-B and C-C, are each arranged essentially parallel to the height direction H and the longitudinal direction L and are spaced from one another essentially in the width direction B.

Fig. 4 shows an example of a second state when coupling the transport box support system 100 with the coupling device 10. The second state shown in Fig. 4 when coupling the transport box support system 100 with the coupling device 10 is an advanced state of coupling compared to the state shown in Fig. 3. In particular, the coupling device 10, as shown in Fig. 4, arranged further forward in the longitudinal direction L or moved further forward than in Fig. 3, for example by an electric scooter 5 moved forward in the longitudinal direction L.

Compared to the illustration in Fig. 3, the actuating projection 50 of the coupling device 10 contacts or touches the front locking device 150. In particular, an actuating portion 52 of the actuating projection 50 contacts or touches a release portion 152 of the front locking device 150.

In addition, in the state as shown in Fig. 4, one of the coupling projections 60, 70, 80 preferably contacts or touches a first frame lifting section 194, as particularly highlighted in Fig. 8b, which is arranged on the frame 110. In other words, in the state as shown in Fig. 4, one or more of the coupling projections 60, 70, 80 of the coupling device 10 can in particular contact a section of the transport box support system 100 and, for example, lift it, i.e., in particular, lift it in the height direction H. At least one or more of the coupling projections 60, 70, 80 of the coupling device 10 can form a coupling level in the height direction H with a first frame lifting section 190 of the transport box support system 100, which raises the frame 110 such that the at least one support element 122 of the front support system 120 no longer contacts the ground 1 and therefore no longer supports the frame 110 against the ground 1.

In the state as shown in Fig. 4, the transport box support system 100, and in particular the transport box 105 arranged on the transport box support system 100, rests partly on the rear support system 140 and partly on the coupling device 10 arranged on the electric scooter 5.

As shown in Fig. 4, the front locking device 150 is still in a position or position that locks the front support system 120. As a result, the at least one support element 122 of the front Support system 120 continues to correspond to the support position, but without actively supporting the transport box support system against the ground, since the transport box support system 100, and in particular the frame 110 of the transport box support system 100, is raised at its front, in other words on the side facing the coupling device 10 in the longitudinal direction L when coupling. This advantageously relieves the load on the front support system 120, so that pivoting of the front support system 120 during coupling is made easier. However, the locking still in place by means of the front locking device 150 means that the front support system 120 is further locked in the support position, so that if the transport box support system 100 and coupling device 10 are incorrectly coupled, the front support system 120 is still available to provide support, thereby providing an advantageously safe coupling.

The rear support system 140, the rear locking device 170, the second pivot section 180 and the rear pivot actuating device 182 of the transport box support system 100, as shown in Fig. 4, have a position or attitude that is substantially unchanged compared to Fig. 3.

Fig. 5 shows, by way of example, a third state when coupling the transport box support system 100 to the coupling device 10. The third state shown in Fig. 5 when coupling the transport box support system 100 to the coupling device 10 is an advanced state of coupling compared to the state shown in Fig. 4. In particular, the coupling device 10, as shown in Fig. 5, is arranged further forward in the longitudinal direction L or shown moved further forward than in Fig. 4, for example by an electric scooter 5 moved forward in the longitudinal direction L.

Compared to the illustration in Fig. 4, the front locking device 150 is in a folded or twisted position as shown in Fig. 5. In other words, the front locking device 150 is, as shown in Fig. 5, in a position in which the front locking device 150 the front Support system 120 is not locked. In other words, the front support system 120, as shown in Fig. 5, is unlocked or released with respect to the front locking device 150. In particular, in Fig. 5 there is no longer any positive connection between the locking device 150 and the front support system 120.

For unlocking, an actuating section 52 of the actuating projection 50 contacts or touches a release section 152 of the front locking device 150, wherein the actuating section 52 and the release section 152 preferably slide against one another during an increasing movement of the coupling device 10 starting from Fig. 4, essentially in the longitudinal direction L. In this case, the front locking device 150 is deflected, pivoted or rotated, in particular deflected, pivoted or rotated in a resilient manner, such that the locking of the front support system 150 is released or unlocked by means of the front locking device 150. The deflection, pivoting or twisting of the front locking device 150 can in particular be a pivoting of the front locking device 150 about an axis extending substantially in the width direction B, preferably a resilient pivoting of the front locking device 150 about an axis extending substantially in the width direction B, particularly preferably an elastically resilient pivoting of the front locking device 150 about an axis extending substantially in the width direction B. This can advantageously provide a passive means for releasing the locking of the front support system, which in turn enables a simplified coupling and safe uncoupling of the transport box support system 100 and the coupling device 10.

In addition, one of the coupling projections 60, 70, 80, in the state as shown in Fig. 5, preferably contacts or touches the first pivot section 130 of the front support system 120, as particularly highlighted in Fig. 9a. In other words, in the state as shown in Fig. 5, one or more of the coupling projections 60, 70, 80 of the coupling device 10 can contact the first pivot section 130 and, for example, press it, i.e. in particular essentially in the longitudinal direction L, but still without pivoting the front support system 120. Starting from Fig. 5, at least one or more of the coupling projections 60, 70, 80 of the coupling device 10 can, upon further movement of the coupling device 10 essentially in the longitudinal direction L, pivot or swivel the front support system 120, in particular pivot or swivel towards the rear support system 140, preferably pivot or swivel into a substantially horizontal position.

The rear support system 140, the rear locking device 170, the second pivot section 180 and the rear pivot actuating device 182 of the transport box support system 100, as shown in Fig. 5, have a position or attitude that is substantially unchanged compared to Fig. 4.

Fig. 6 shows, by way of example, a fourth state when coupling the transport box support system 100 to the coupling device 10. The fourth state shown in Fig. 6 when coupling the transport box support system 100 to the coupling device 10 is an advanced state of coupling compared to the state shown in Fig. 5. In particular, the coupling device 10, as shown in Fig. 6, is arranged further forward in the longitudinal direction L or shown moved further forward than in Fig. 5, for example by an electric scooter 5 moved forward in the longitudinal direction L.

Compared to the illustration in Fig. 5, the front support system 120 is pivoted into the transport position according to Fig. 6. The front support system 120 is in a substantially horizontal position, for example. As shown in Fig. 6, the at least one support element 122 of the front support system 120 extends in the transport position substantially in the longitudinal direction L, in particular towards the rear support system 140, preferably in such a way that it is at least partially surrounded by a frame casing section 111 of the frame 110, which extends along a circumference of the frame 110 similar to an apron or a casing substantially in the height direction H. As a result, the front support system 120 is advantageously protected in the transport position, at least partially arranged within the frame 110.

The front support system 120, in particular the pivoting section 130 of the front support system 120, can, as shown in Fig. 6, rest on the coupling device 10 at least in sections and can thereby be held in the transport position.

Compared to the illustration in Fig. 5, the rear locking device 170 is in a folded or twisted position as shown in Fig. 6. In other words, the rear locking device 170, as shown in Fig. 6, is in a position in which the rear locking device 170 does not lock the rear support system 140. In still other words, the rear support system 140, as shown in Fig. 6, is unlocked or released with respect to the rear locking device 170. In particular, in Fig. 6 there is no longer any positive connection between the rear locking device 170 and the rear support system 140.

For unlocking, one of the coupling projections 60, 70, 80 contacts or touches a rear release device 172, whereby the rear release device 172 is deflected, in particular rotated, turned or pivoted, wherein the deflection of the rear release device 172 is passed on or transmitted to the rear locking device 170 by the release coupling element 174. By passing on or transmitting the deflection of the rear release device 172 to the rear locking device 170, the rear locking device 170 is deflected, pivoted or twisted, in particular deflected, pivoted or twisted in a resilient manner, such that the lock of the rear support system 140 is released or unlocked by means of the rear locking device 170. The deflection, pivoting or twisting of the rear locking device 170 can in particular be a pivoting of the rear locking device 170 about an axis extending substantially in the width direction B, preferably a resilient pivoting of the rear locking device 170 about an axis extending substantially in the width direction B, particularly preferably an elastically resilient pivoting of the rear locking device 170 about an axis extending substantially in the width direction B. This can advantageously provide a passive means for releasing the locking of the rear support system 140, which in turn enables a simplified and safe coupling and uncoupling of the transport box support system 100 and the coupling device 10.

As is clear from a comparison of Figures 5 and 6, the rear release device 172 has in particular a projection which forms a release actuation section 176, wherein the projection, as shown in Fig. 5, extends in particular in an alignment of one of the coupling projections 60, 70, 80, in particular in an alignment of one of the coupling projections 60, 70, 80 guided by at least one of the coupling guides 116 which are fixed to the frame 110. As shown in Fig. 6, one of the coupling projections 60, 70, 80 contacts or touches and in particular presses the release actuation section 176 designed as a projection when passing through one of the coupling guides 116, whereby the rear release device 172 is deflected as described above.

In addition, in the state as shown in Fig. 6, one of the coupling projections 60, 70, 80 preferably contacts or touches a pivot actuating section 186 of the rear support system 140, as particularly highlighted in Fig. 10c. In other words, in the fourth state, as shown in Fig. 6, in particular one or more of the coupling projections 60, 70, 80 of the

Coupling device 10 can contact the pivot actuation section 186 coupled to the second pivot section 180 by means of the pivot coupling element 184 and press it, for example, i.e. in particular essentially in the longitudinal direction L, but without pivoting the rear support system 140. Starting from Fig. 6, at least one or more of the coupling projections 60, 70, 80 of the coupling device 10 can, upon further movement of the coupling device 10 essentially in the longitudinal direction L, pivot or swivel the rear support system 140, in particular pivot or swivel it towards the front support system 120, preferably in a Pivot or swivel to a substantially horizontal position.

The rear support system 140, the second pivot section 180 and the rear pivot actuating device 182 of the transport box support system 100, as shown in Fig. 6, have a position or attitude that is substantially unchanged compared to Fig. 5.

Fig. 7 shows, by way of example, a fifth state when coupling the transport box support system 100 to the coupling device 10. The fifth state shown in Fig. 7 when coupling the transport box support system 100 to the coupling device 10 is an advanced state of coupling compared to the state shown in Fig. 6. In particular, the coupling device 10, as shown in Fig. 7, is arranged further forward in the longitudinal direction L or shown moved further forward than in Fig. 6, for example by an electric scooter 5 moved forward in the longitudinal direction L.

Compared to the illustration in Fig. 6, the rear support system 140 is pivoted into the transport position according to Fig. 7. In this case, the rear support system 140 is, for example, in a substantially horizontal position. As shown in Fig. 7, the at least one support element 142 of the rear support system 140 extends in the transport position substantially in the longitudinal direction L, in particular towards the front support system 120, preferably in such a way that it is at least partially surrounded by the frame casing section 111 of the frame 110, which extends along a circumference of the frame 110 similar to an apron or a casing substantially in the height direction H. As a result, the rear support system 140 is advantageously protected in the transport position, at least partially arranged within the frame 110. Furthermore, as illustrated by Fig. 7, the front support system 120 and the rear support system 140 are advantageously arranged in a space-saving manner on the frame 110 in the transport position, so that a comparatively large space is provided for the transport box 105 as an exemplary transport container when transporting goods or persons. The front support system 120, in particular the pivoting section 130 of the front support system 120, can, as shown in Fig. 7 as well as in Fig. 6, rest on the coupling device 10 at least in sections and can thereby be held in the transport position.

As shown in Fig. 7, the rear support system 140 is held in the transport position in particular by means of the deflected rear pivot actuating device 182, which is coupled to the second pivot section 180 of the rear support system 140 via the rigid pivot coupling element 184.

Compared to the illustration in Fig. 6, the rear pivot actuating device 182 is in a deflected position according to the illustration in Fig. 7. When moving into the deflected position, the pivot coupling element 184 transfers the deflection of the rear pivot actuating device 182 to the second pivot section 180, which is arranged on the rear support system 140, so that the rear pivot system 140 is pivoted from the support position into the transport position.

To pivot the rear support system 140, one of the coupling projections 60, 70, 80 deflects the rear pivot actuating device 182, whereby the rear pivot actuating device 182 is in particular rotated, turned or pivoted. The deflection of the rear pivot actuating device 182 is passed on or transmitted to the second pivot section 180 of the rear support system 140 by the pivot coupling element 184. The deflection passed on or transmitted to the second pivot section 180 by means of the pivot coupling element 184 can in particular comprise substantially pulling the second pivot section 180, wherein the second pivot section 180 is pulled substantially in a direction parallel to the longitudinal direction L and opposite to it. By pulling the second pivoting section 180 towards the front support system 120, the rear support system 140 is pivoted accordingly towards the front support system 120, in particular pivoted from the support position into the transport position. In exemplary embodiments, and as shown in Fig. 7, the deflection of the rear pivot actuating device 182 can be a rotary or turning deflection of the rear pivot actuating device 182. By means of the respective connection of the pivot coupling element 184 to the rear pivot actuating device 182 and the second pivot section 180, the deflection of the rear pivot actuating device 182 is converted into a predetermined deflection of the second pivot section 180, in particular from a substantially rotary deflection, starting from the rear pivot actuating section 182, to a substantially translational deflection of the second pivot section 180.

By passing on or transmitting the deflection of the rear pivot actuating device 182 to the second pivot section 180, the rear support system 140 is deflected, pivoted or rotated, in particular deflected, pivoted or rotated in a resilient manner. The deflection, pivoting or twisting of the rear support system 180 can in particular be about an axis extending substantially in the width direction B, preferably a resilient pivoting of the rear support system 140 about an axis extending substantially in the width direction B, particularly preferably an elastically resilient pivoting of the rear support system 140 about an axis extending substantially in the width direction B. This can advantageously provide a passive means for pivoting the rear support system 140, which in turn enables a simplified and safe coupling and decoupling of the transport box support system 100 and the coupling device 10.

As is clear from a comparison of Figures 6 and 7, the rear pivot actuating device 182 has in particular a projection which forms a pivot actuating section 186, wherein the projection, as shown in Fig. 6, extends in particular in an alignment of one of the coupling projections 60, 70, 80, in particular in an alignment of one of the coupling projections 60, 70, 80 guided by at least one of the coupling guides 116 which are fixed to the frame 110. As shown in Fig. 6, contacted or touched and in particular presses one of the coupling projections 60, 70, 80, when passing through one of the coupling guides 116, presses against the pivot actuating section 186 designed as a projection, whereby the rear pivot actuating device 182 is deflected, as described above. By further movement of the coupling device 10 essentially in the longitudinal direction L, one of the coupling projections 60, 70, 80 presses against the pivot actuating section 186, whereby the rear pivot actuating device 182 is deflected, in particular rotated, preferably rotated in a resilient manner.

Due to the upstream arrangement of the pivot actuating device 182, the rear support system 140 can advantageously be brought into a transport position, while the coupling device 10 can be designed to be comparatively short and in particular to save space.

In addition, in the state as shown in Fig. 6, one of the coupling projections 60, 70, 80 preferably contacts or touches a pivot actuation section 186 of the rear support system 140, as particularly highlighted in Fig. 10c. In other words, in the state as shown in Fig. 6, one or more of the coupling projections 60, 70, 80 of the coupling device 10 can contact the pivot actuation section 186 coupled to the second pivot section 180 by means of the pivot coupling element 184 and, for example, press it, that is to say in particular press it substantially in the longitudinal direction L. Starting from Fig. 6, at least one or more of the coupling projections 60, 70, 80 of the coupling device 10 can, upon further movement of the coupling device 10 substantially in the longitudinal direction L, pivot or swivel the rear support system 140, in particular pivot or swivel towards the front support system 120, preferably pivot or swivel into a substantially horizontal position.

As both support systems 120, 140 are in the transport position, as shown in Fig. 7, the transport box support system 100 and, if applicable, the Transport box 105, on the coupling device 10, and in particular on the

Electric scooter 5, which is thereby ready to transport the transport box support system 100 and a transport box 105 arranged thereon.

In Figures 8a to 10c, various details of the respective states, as already described with reference to Figures 3 to 7, are illustrated again.

Fig. 8a shows a side sectional view of the section A-A according to the transport box support system 100 and the docking device 10 as shown in Fig. 3, according to an embodiment of the present invention.

As shown in Fig. 8a and already highlighted in Fig. 3, in this exemplary first state the transport box support system 100 and the coupling device 10 are shown in a decoupled state.

As shown in Fig. 8a, a first frame lifting section 190 is arranged on the frame 110 of the transport box support system 100 in the longitudinal direction L when coupling with the coupling device 10, in particular arranged underneath the frame 110.

As shown in Fig. 8a, the frame lifting section 190 can have an inclination or slope on its side facing in the longitudinal direction L when coupled to the coupling device 10. The inclination or slope of the frame lifting section 190 can be shaped in particular such that the frame lifting section 190 has an increasing height in the height direction H with increasing extension in a direction substantially opposite to the longitudinal direction L. This advantageously allows the frame lifting section 190 to slide off one of the coupling projections 60, 70, 80 during coupling.

In Fig. 8a, the frame lifting section 190 and the first coupling projection 60 are shown as an example, wherein the frame lifting section 190 is connected to the first coupling projection 60, when the frame lifting section 190 rests on the first coupling projection 60, form a height level along the height direction H, which preferably causes the at least one support element 122 of the front support system 120 to be lifted off the ground 1.

The coupling projections 60, 70, 80 and in particular the first coupling projection 60 can have a lifting section 62 on a side facing the transport box support system 100 during coupling. The lifting section 62 can have an increasing height in the height direction H, in particular with increasing extension in a direction substantially parallel to the longitudinal direction L. This can advantageously facilitate sliding of the first frame lifting section 190 on the lifting section 62 of the respective coupling projection 60, 70, 80 during coupling.

In exemplary embodiments, the first frame lifting section 190 may be formed as part of one of the coupling guides 116, thereby ensuring secure guidance of the respective coupling projection 60, 70, 80 to the first

Frame lifting section 190 can be ensured.

Fig. 8b shows a side sectional view of the section A-A according to the transport box support system 100 and the docking device 10 as shown in Fig. 4, according to an embodiment of the present invention.

As shown in Fig. 8b and already highlighted in Fig. 4, in this exemplary second state, the transport box support system 100 and the coupling device 10 are shown in a partially coupled state, but not fully coupled state. Relative to the first state according to Figures 3 and 8a, the coupling device 10 is shown moved or positioned further in the longitudinal direction L in the second state according to Figures 4 and 8b.

As shown in Fig. 8b, the first frame lifting section 190 is located by a movement of the coupling device 10 substantially in the longitudinal direction L in the second state now rests on the first coupling projection 60 of the coupling device 10. As a result, preferably a part of the transport box support system 100 rests on the coupling device 10 and on the electric scooter 5 supporting the coupling device 10. At the same time, preferably the at least one support element 122 of the front support system 120 is relieved, in particular such that it does not perform any function of supporting the transport box support system 100 with respect to the ground 1, as can be assumed in particular with a substantially flat ground 1.

Fig. 8c shows a side sectional view of the section B-B according to the transport box support system 100 and the docking device 10 as shown in Fig. 4, according to an embodiment of the present invention.

As shown in Fig. 8c and already highlighted in Fig. 4, in this exemplary second state, the transport box support system 100 and the coupling device 10 are shown in a partially coupled state, but not fully coupled state. Relative to the first state according to Fig. 8a, the coupling device 10 is shown moved or positioned further in the longitudinal direction L in the second state according to Fig. 8c.

As shown in Fig. 8c, the actuating projection 50 of the coupling device 10 touches or contacts a release section 152 of the front locking device 150 facing the coupling device 10 when coupling. The front locking device 150 is preferably in a pre-tensioned position, which locks the front support system 120 in the support position, in particular locks it in a form-fitting manner. The actuating projection 50 is in particular rigidly arranged, fastened or designed on the coupling device 10, so that it advantageously causes a deflection or tilting of the front locking device 150 in a passive manner when the coupling device 10 moves in the longitudinal direction L.

As highlighted in Fig. 8c, the front locking device 150 in particular a groove 154 which surrounds a section of the front support system 120, in particular a groove 154 which surrounds in a form-fitting manner, in particular a groove 154 which surrounds both sides with respect to the longitudinal direction L. The front support system 120 can have the front reinforcing element 124 in the region of the front locking device 150, which in particular has a stiffening, damping and/or anti-slip effect.

Fig. 8d shows an enlargement of the side sectional view of the section B-B according to the transport box support system 100 and the coupling device 10, as shown in Fig. 4, according to an embodiment of the present invention. The enlargement relates in particular to the area of the front locking device 150, as also shown in Fig. 8c.

As shown in Fig. 8d, the actuating projection 50 of the coupling device 10 touches or contacts the release section 152 of the front locking device 150 facing the coupling device 10 when coupling. In particular, the actuating section 52 of the actuating projection 50 touches the release section 152. In this case, at least one of the actuating section 52 and the release section 152 is preferably formed inclined or obliquely, in particular with a height in the height direction H that increases parallel to the extension opposite to the longitudinal direction L. This advantageously has the effect that with increasing movement of the coupling device 10 in the longitudinal direction L, the front locking device 150 is deflected or tilted, in particular about an axis that extends essentially in the width direction, is deflected or tilted, preferably deflected or tilted in a resilient manner, as is particularly illustrated by Figures 9b and 9c.

Fig. 9a shows a side sectional view of the section A-A according to the transport box support system 100 and the docking device 10 as shown in Fig. 5, according to an embodiment of the present invention.

As shown in Fig. 9a and already highlighted in Fig. 5, in this exemplary third state, the transport box support system 100 and the coupling device 10 are shown in a partially coupled state, but not fully coupled state. Relative to the second state according to Figures 4, 8b, 8c and 8d, the coupling device 10 is shown moved or positioned further in the longitudinal direction L in the third state according to Figures 5 and 9a.

As shown in Fig. 9a, the first coupling projection 60 touches or contacts the first pivot section 130 of the front support system 120. The front support system 120 is preferably in the support position, in particular pre-tensioned in the support position. The first pivot section 130, as shown in Fig. 9a, is arranged in particular below a joint of the front support system 120, i.e. in the height direction H below a joint about which the front support system 120 can be pivoted, so that pressing the first pivot section 130 essentially in the longitudinal direction L causes the front support system 120 to pivot from the support position into the transport position, in particular causes the front support system 120 to pivot towards the rear support system 140.

Fig. 9b shows a side sectional view of the section B-B according to the transport box support system 100 and the coupling device 10, as shown in Fig. 5, according to an embodiment of the present invention. Fig. 9c shows an enlargement in the area of the front locking device 150 from Fig. 9b.

As shown in Figures 9b and 9c and already highlighted in Figure 5, in this exemplary third state the transport box support system 100 and the coupling device 10 are shown in a partially coupled state, but not fully coupled state. Relative to the second state according to Figures 4, 8b, 8c and 8d, the coupling device 10 is shown in the third state according to Figures 5, 9b and 9c moved or positioned further in the longitudinal direction L.

In Figures 9b and 9c, the front locking device 150 is shown in a deflected or folded position, in particular in a position in which the front Support system 120 is shown in the non-locking position. The front locking device 150 rests on the actuating projection 50 with a section facing the coupling device 10, whereby the deflected or folded position, in other words the non-locking position of the front locking device 150, is fixed.

As illustrated in particular by Fig. 9c, in the third state, as also described in particular by Fig. 5, the positive connection between the front locking device 150 and the front support system 120 is released or unlocked. This enables the pivotability of the front support system 120. As shown in Figures 9b and 9c, the front reinforcement element 124 can be arranged on the front support system 120 facing the rear support system 140 in the longitudinal direction L. In alternative embodiments, the front reinforcement element 124 can be arranged facing away from the rear support system 140 in the longitudinal direction L or can be arranged on both sides in the longitudinal direction L on the front support system 120, in particular on the first pivot section 130 of the front support system 120.

In the background of Figures 9b and 9c, the first coupling projection 60 is shown, which in the third state, and thus after the locking of the front support system 120 has been unlocked by the front locking device 150, is configured to touch or press the first pivot portion 130 of the front support system 120.

Fig. 10a shows a side sectional view of the section C-C according to the transport box support system 100 and the docking device 10 as shown in Fig. 6, according to an embodiment of the present invention.

As shown in Fig. 10a and already highlighted in Fig. 6, in this exemplary fourth state, the transport box support system 100 and the coupling device 10 are shown in a partially coupled state, but not fully coupled state. Relative to the third state according to the Figures 5, 9a, 9b and 9c, the coupling device 10 is shown in the fourth state according to Figures 6 and 10a further moved or positioned in the longitudinal direction L.

As shown in Fig. 10a, the front locking device 150 has returned to its original position, thereby reducing the preload and advantageously increasing the longevity of the passively acting front locking device 150. The front locking device 150 does not lock the front support system 120, since the latter has already been pivoted into the transport position, in particular towards the rear support system 140, for example pivoted into a substantially horizontal position.

As shown in Fig. 10a, the second coupling projection 70 has pressed the release actuation section 176 forward in the longitudinal direction L, and thereby deflected the rear release device 172, in particular deflected it rotationally, in particular deflected it rotationally about an axis which extends substantially along the height direction H. By means of the release coupling element 174, the deflection of the rear release device 172 is transmitted or passed on to the rear locking device 170. In this case, a lock of the rear support system 140 is released by the rear locking device 170, as a result of which the rear support system 140, as shown in Fig. 10a, is in an unlocked, i.e. unlocked or released, state.

Since the second pivot section 180, as shown in Fig. 10a, has not yet been actuated, the rear support system 140 is still arranged in the support position. However, as highlighted in the background of Fig. 10a, the first coupling projection 60 touches or contacts the pivot actuating section 186, which is coupled to the second pivot section 180 in particular via the pivot coupling element 184, so that upon further movement of the coupling device 10 in the longitudinal direction L, the second pivot section is deflected, corresponding to a deflection originating from the rear pivot actuating device 182, which in turn is brought about in particular by a movement of the first coupling projection 60 in the longitudinal direction L. As also shown in Fig. 10a, the frame 110 can in particular have a second frame lifting section 194 which is configured to be lifted or received by one of the three coupling projections 60, 70, 80, analogously to the embodiments as highlighted for the frame lifting section 190. This advantageously allows the rear support system 140 to be partially lifted from the ground 1, which facilitates pivoting of the rear support system 140 during further coupling.

Fig. 10b shows a perspective view in the area of the rear release device 172, according to the fourth state, as highlighted in Figures 6 and 10a.

As shown in Fig. 10b, the second coupling projection 70 is preferably configured to slidably receive the second frame lifting section 194 during a movement of the coupling device 10 in the longitudinal direction L and thereby to lift it in a particularly gentle manner.

Furthermore, Fig. 10b shows in particular that the second coupling projection 70 is configured to press the release actuation section 176 of the rear release device 172 out of alignment with the second coupling projection 70 through one of the coupling guides 116. As a result, the rear release device 172 is deflected rotationally, preferably deflected rotationally in a resilient manner, as shown in Fig. 10b. Due to the deflection of the rear release device 172, a connection of the release coupling element 174 to the release device 172 is correspondingly deflected. The release coupling element 174 is preferably designed as a rigid element, so that the release coupling element 174 transmits the deflection of the rear release device 172 to the rear locking device 170, in particular such that the rear support system 140 is unlocked, in particular is unlocked from the positive connection with the rear locking device 170.

Fig. 10c shows a side sectional view of the section AA according to the transport box support system 100 and the coupling device 10, as in Fig. 7 shown, according to an embodiment of the present invention.

As shown in Fig. 10c and already highlighted in Fig. 7, in this exemplary fifth state, the transport box support system 100 and the coupling device 10 are shown in the coupled state. Relative to the fourth state according to Figures 6, 10a and 10b, the coupling device 10 is shown moved or positioned further in the longitudinal direction L in the fifth state according to Figures 7 and 10c.

As shown in Fig. 10c, in the coupled state both the front support system 120 and the rear support system 140 are arranged in the transport position, in particular arranged essentially horizontally and facing each other. This enables an advantageous space-saving arrangement of the support systems 120, 140 during transport with the electric scooter 5.

As is clear from a comparison of Figures 10a and 10c, the pivot actuating section 186 in Figure 10c is in particular in a deflected position shown in relation to Figure 10a. As is further clear from Figures 7 and 10c in combination, the first coupling projection 60 is configured to press the pivot actuating section 186 of the rear pivot actuating device 182 along the alignment of the first coupling projection 60, guided by the coupling guide 116. As a result, the rear pivot actuating device 182 is rotationally deflected, preferably rotationally deflected in a resilient manner, as shown in Figure 10c. As a result of the deflection of the rear pivot actuating device 182, a connection of the pivot coupling element 184 to the rear pivot actuating device 182 is correspondingly deflected. The pivot coupling element 184 is preferably designed as a rigid element, so that the pivot coupling element 184 transmits the deflection of the rear pivot actuating device 182 to the second pivot section 180, in particular such that the rear support system 140 is pivoted, in particular pivoted from the support position into the transport position, preferably pivoted towards the front support system 120. By means of the rear pivot actuating device 182 arranged upstream of the second pivot section 180 of the rear support system 140, the rear support system 140 can advantageously be pivoted, while the coupling device 10 can advantageously be designed to be short and space-saving.
