    The invention relates to a support arrangement for a two-wheeler with a drive and a two-wheeler with such a support arrangement, comprising a support head, a support that can assume a first or a second position, a spring which is arranged between the support and the support head is, as well as a sensor.
    Support arrangements for two-wheelers with drive secure the two-wheeler by unfolding a support that keeps the two-wheeler upright. Support arrangements can impede a safe journey if the support is not folded in while driving. Numerous solutions are known in which a one-part or multi-part sensor arrangement detects the position of the support and indicates when the support is not folded in at the start of a journey. There are solutions in which components of a multi-part sensor arrangement are attached to the support arrangement, but also to the frame of the two-wheeler. Such arrangements as z. B. are disclosed in DE 100 39 021 A1, are complex and require a complex installation.
    A one-piece sensor assembly, that is, an assembly that is attached only to the support assembly is z. B. disclosed in DE 100 02 731 A1. The support has an extension that protrudes beyond the pivot point and a sensor detects the position of the extension of the support. This support arrangement, which is already simplified compared to a multi-part sensor arrangement, still requires modifications to the support.
    It is the object of the invention to propose a further simplified and reliable support arrangement for a two-wheeled vehicle with a drive.
    [0005] The object is achieved with a support arrangement according to claim 1.
    The inventive support arrangement for a two-wheel drive with a drive has a support head, a support which assumes a first or a second position, a spring which is arranged between the support and support head, and a sensor and is characterized in that the sensor detected a first or a second position of the support. The drive can be any drive, e.g. B. an internal combustion engine or an electric drive. The two-wheeler can be a bicycle with a pedal drive or a motorcycle without a pedal drive. The sensor preferably detects a first or a second position of the spring, the position of the spring correlating with the position of the support.
    When installed, the support head is attached to the frame of a two-wheeler with a drive, usually by screwing. The support head receives the support, which extends elongated away from the support head. The support is long enough to hold the two-wheeler in a vertical or slightly inclined position starting from the support head. The support pivots about an axis which is arranged in the support head. It swivels from a first position in which it extends to the ground and supports the two-wheeler in a second position in which it is essentially parallel to the ground on which the two-wheeler is located or approximately parallel to the axis that extends through the hubs of the two wheels of the two-wheeler is defined. The support does not have to be arranged exactly parallel, it can also be arranged at an angle, provided it does not interfere with the journey of the two-wheeler. In a simple arrangement, the sensor is arranged in such a way that it indicates when the support is folded down in a first position or extended in a second position, i.e. when it supports the two-wheeler when it is stationary.
    To secure the support in the first or the second position, the support is often loaded by a spring which is mounted between the support and the support head. The spring can be on the outside, which is inexpensive and allows a broken or damaged spring to be changed easily. The spring can be located on the inside, preferably in a recess in the support head, so that the spring is well protected from contamination and damage.
    The sensor detects the position of the support either directly or, according to an advantageous embodiment, it detects the position of the spring that secures the support in a first or a second position. The sensor detects z. B. as a mechanical, optical, magnetic or electronic sensor, whether the support or the spring is near the sensor or not. Sensors that are suitable for detecting the position of an object are known per se and are available. A sensor that is attached to the support head to monitor the position of an internal spring is well protected against dirt and damage and reliably supplies correct signals.
    It is further preferred that the sensor is connected to a control unit, a starter unit or a lock. In this way, the signal that the sensor perceives is sensibly processed. The sensor is usually connected to the control or starter unit or the lock by a cable in order to forward the detected signal. Wireless transmission is also possible, but a cable between the sensor and the control or starter unit or lock has proven to be useful.
    The control unit is known per se, it processes the signal from the sensor and converts it into an instruction to lock the drive or a release so that the two-wheeler can start moving using the drive. The sensor can also transmit a signal to a starter unit when the support is folded in and thus no longer opposes the movement of the two-wheeler, so that the starter unit can start undisturbed. Alternatively, the signal from the sensor can block the starter unit as long as the support is extended. If the sensor is connected to a lock, the lock remains active as long as the sensor reports that the support is extended. If the support is folded in, the lock releases the two-wheeler and the two-wheeler with drive can be moved.
    The sensor is advantageously permanently installed on the support head and is arranged so that it preferably detects the support or the spring in a first or in a second position. The first position covers the support in the folded position. The second position captures the support in the unfolded position. The sensor detects one of two states, first: The spring is in the detected position, e.g. B. first position, the support is extended or folded down towards the ground, alternatively in a second position: the spring is not in the detected position, the support is folded. So it does not have to be recorded where exactly the spring is. Since there are only two relevant positions, folded or folded, it is sufficient to monitor only one position in order to obtain the desired information about the position of the support. According to a first embodiment, the sensor is arranged in such a way that it monitors whether the support is folded in, that is to say according to the definition of this description of the first position. According to a second embodiment, the sensor is arranged in such a way that it monitors whether the support is folded out or extended, that is to say according to the definition of this description of the second position. This ensures that the two-wheeled vehicle will not start under any circumstances, as it will not be ready to drive when the support is extended. Since it is important for driving safety that the support is folded in correctly, the signal that the support is correctly folded in after a second execution ensures that the two-wheeled vehicle is ready to drive.
    The invention further relates to a two-wheeled vehicle with the support arrangement described above.
    [0014] Details of the invention are described using exemplary embodiments. Show it:<tb> Fig. 1 <SEP> a view of the support arrangement according to a first embodiment with the support extended, that is to say in a first position;<tb> Fig. 2 <SEP> a view of a support arrangement according to FIG. 1 with the support folded in, that is to say in a second position;<tb> Fig. 3 <SEP> a view of the support arrangement according to a second embodiment with the support extended;<tb> Fig. 4 <SEP> a view of a support arrangement according to FIG. 3 with the support folded in;<tb> Fig. 5 <SEP> a view of the support arrangement according to a third embodiment with the support extended;<tb> Fig. 6 <SEP> a view of a support arrangement according to FIG. 5 with the support folded in.
    1 and 2 show a support arrangement 2 according to a first embodiment of the invention with the support extended (FIG. 1) and with the support folded in (FIG. 2). The support arrangement has a support head 4, on which a support 6 is arranged, which is pivotable about an axis 8 in the support head. The support 6 is held by a spring 10 in a second position according to FIG. 2, in which the support 6 is approximately parallel to the frame 12 of a two-wheeler 14, here a bicycle 14 with an electric drive (not shown). In the first position according to FIG. 1, the support 6 is arranged approximately perpendicular to the axis which results from the hubs of the front and rear wheels of the two-wheeler 14. In the second position, the support 6 according to FIG. 2 is arranged approximately parallel to the axis which is defined by the hubs of the two wheels of the two-wheeler 14. The support 6 can be arranged at an acute angle to this axis; it is crucial that the support 6 does not impede the movement of the two-wheeler 14.
    On the support head 4, which is screwed to the frame 12 of the two-wheeler 14, a sensor 16 is attached. The sensor 16 is a magnetic sensor, that is to say a sensor that detects changes in the magnetic field and reports them as signals to a control unit, a starter unit or a lock (not shown here). The signals are transmitted through a cable which originates from the sensor 16 and extends from the support head 4 along the frame 12 to the above-mentioned control or starter unit or lock. The sensor 16 detects the position of the support 6 only in the first position, that is to say only when the support 6 is extended, as shown in FIG. 1. The two-wheeler 14 is at a standstill and is held upright by the support 6, which extends between the support head 4 and the ground. The sensor 16 does not detect the position of the support 6 in the folded, second position, as can be seen from FIG. 2. The sensor 16 sends no signal when the support 6 is in the second position.
    The exemplary embodiments are explained using a sensor 16 which sends a signal when the support 6 is in the first position and which does not send a signal when the support 6 is in the second position. It is expressly noted that alternatively a signal can only be sent when the support 6 is in the second position or that different signals are sent, depending on the position in which the support 6 is located.
    The support 6 is in the second position in the immediate vicinity of the sensor 16 and thus changes the magnetic field in the vicinity of the sensor 16. In this state, the sensor 16 sends a signal that the control or starter unit receiving the signal or lock receives. This arrangement of the sensor 16 in the support head is simple and inexpensive to implement and the sensor 16 reliably detects the position of the support 6 in the first position.
    In the second embodiment according to FIG. 3 and FIG. 4, the same reference numerals are used for the same features. In contrast to the first embodiment, the sensor 16 does not detect the position of the support 6 but the position of the spring 10 in the second embodiment Support head 4. The lower end 22 of the spring 10 is attached to the support 6. When changing from the first to the second position, the lower end 22 of the spring 10 is pivoted together with the support 6 by approximately 90 ° and is thus spatially displaced. In order to detect the position of the spring 10, the sensor 16 is placed in the support head 4 in such a way that it is covered by the spring 10 when the support 6 is in a first position, and that the spring 10 is at a considerable distance from the sensor 16 is placed when the support 6 is in a second position. The spring 10 influences the magnetic field of the sensor 16 when the support 6 according to FIG. 3 is extended in a first position in order to support the two-wheeler. The spring 10 has no influence on the sensor 16 when, as shown in FIG. 4, the support 6 is in a second position, that is to say folded in the driving position. The sensor 16 thus detects two different positions of the support 6, which allow the sensor to send discrete signals. In this position, the sensor 16 simply and reliably receives and sends signals relating to the position of the support 6 in the first position, and it is also less prone to soiling and damage.
    According to a third embodiment, which is shown in FIGS. 5 and 6, the spring 10 is protected in a recess 24 in the support head 4. The sensor 16 is mounted in the recess 24 directly adjacent to the position of the spring 10 which it assumes in the first position. As shown in FIG. 5, the sensor 16 detects the position of the spring 10 in the first position and sends a corresponding signal. If the position of the spring 10 is in the second position, as shown in FIG. 6, the sensor 16 either sends no signal or sends another signal. The sensor 16 is attached to the inside in the support head 4 and is thus well protected from contamination and damage.
    The spring 10 influences the magnetic field of the sensor 16 when the support 6 is extended in the first position and the spring 10 is in the immediate vicinity of the sensor 16. The magnetic field of the sensor 16 is influenced differently or not at all when the support 6 is in the second position. In this case, the sensor 16 sends no signal or a different signal.
    The following applies to all embodiments of the invention: If the signal is received by a control unit, the control unit controls the drive so that starting from standstill is not possible. If the signal from the sensor 16 is received by a starter unit, the starter unit remains switched off as long as the sensor 16 sends the signal that the support 6 is in the first position. The same applies to a lock that is connected to the sensor 16. As long as the sensor 16 sends the signal that the support 6 is in the first position, the lock will prevent the two-wheeler from starting. If the support 6 of the two-wheeler 16 is in the second position, the sensor 16 either sends no signal or sends a different signal. In this way it is indicated that the spring 10 is not in the first but in the second position. The signal for displaying the support 6 in the first position is preferably only switched off or changed when the spring 10 has moved sufficiently far in the direction of the second position, for example half or two thirds of the distance to the second position. This distance can be adjusted depending on the requirements for the position of the support 6 between the two positions. The control or starter unit or lock are therefore only blocked by the signal which indicates that the spring 10 is in the first position, that is to say that the support 6 is extended.
    It also applies to all embodiments of the invention that a sensor 16 is preferably used, which is fitted into the support head 4. The support assembly 2 is usually made of metal, e.g. B. made of die-cast aluminum, but can also be made of plastic in simple designs. A possibly required recess for receiving the sensor 16 can already be provided in the casting mold for the support head 4, for example. Alternatively, it is easily possible to edit the support head 4 subsequently in order to create a recess for the sensor 16.
    The signal that the sensor 16 sends out is preferably transmitted through a cable. The cable can run on the support head 4, but preferably at least partially. The support arrangement 2 according to the invention is advantageously supplied with the cable that is then led on or in the frame 12 to the receiver, that is to say to a control or starter unit or to a lock, and is connected there. The advantage of this embodiment is that the support arrangement 2 can be retrofitted at any time, with the sensor 16 not having to be mounted separately on the two-wheeler 14 and, if applicable, the cable on the support head 4. The sensor 16 is installed at the factory when the spring 10 and the support 6 are assembled and, if necessary, connected to the cable. All that remains is the cable that is to be laid and connected on or in the frame 12 of the two-wheeler 14.
