Description

[0015] In one embodiment, the kickstand for two-wheelers according to the invention is attached to a two-wheeler.

[0016] Possible techniques for attaching the kickstand for two-wheelers to a two-wheeler are known to the person skilled in the art and comprise, for example, adhesive connections, welded connections and screw connections.

[0017] Two-wheelers in the meaning of the current invention comprise non-motorized two-wheelers, for example bicycles, and motorized two-wheelers, for example motorcycles, mopeds, motor scooters, but also motorized bicycles.

[0018] Bicycles within the scope of the invention comprise non-motorized bicycles and motorized bicycles. Motorized bicycles are those with an (additional) electric drive. Examples of this are e-bikes and pedelecs or S-pedelecs.

[0019] If a vacuum is present in at least one of the cavities of the kickstand for two-wheelers, the two-wheeler with the kickstand for two-wheelers according to the invention has superior stability in the parking position since the vacuum adheres the foot 6 and thus the kickstand for two-wheelers and the two-wheeler onto the surface.

[0020] According to the invention, the parking position or parking or park mode mean that the two-wheeler is standing at a place with the kickstand for two-wheeler extended and the foot 6 contacts a surface.

[0021] Preferably kickstands for two-wheelers according to the current invention, which are attached to a two-wheeler, can be extended/folded out or retracted/folded in, just like conventional kickstands for two-wheelers. In the extended state, a kickstand for two-wheelers supports the stability of the attached two-wheeler in the park mode by contacting a surface such as the ground. In retracted state, no surface (or at most a surface on the two-wheeler) is contacted so that the two-wheeler can be moved or driven. Accordingly, the kickstand for two-wheelers possesses, for example, a ball-and-socket joint 3 for extending or retracting the kickstand for two-wheelers, when attached to a two-wheeler.

[0022] In the context of the invention, kickstands for two-wheelers comprise kickstands for two-wheelers which are known to a person skilled in the art, such as, for example, side and rear kickstands. Both single leg, as well as double leg kickstands, are both kickstands according to the invention.

[0023] When using double leg kickstands or multiple kickstands or kickstands with several feet, a vacuum can be produced in only one of these feet, but also in several or all of them.

[0024] In addition to the increased standing properties, the adhering of the kickstand for two-wheelers to a surface prevents unauthorized movement of the two-wheeler, whereby the kickstand for two-wheelers also serves as an anti-theft protection of the two-wheeler.

[0025] If, for example, a kickstand for two-wheelers according to the invention, which is attached to a two-wheeler, has ground contact (the corresponding two-wheeler thus parks), the at least one cavity of the suction base can be evacuated so that a vacuum exists in this at least one cavity. A corresponding strength of the vacuum (or the level of the pressure difference) prevents both the unlawful (theft) and the unwanted (falling over) movement of the two-wheeler.

[0026] According to the invention, evacuation means the generation of a vacuum, that is, a pressure which is lower than the ambient pressure.

[0027] The kickstand for two-wheelers according to the invention can have a pressure reading, which indicates the magnitude of the vacuum in the suction base 6. Such a pressure reading can also or instead be located on the two-wheeler.

[0028] In one embodiment the removal/or the build-up of the vacuum in the kickstand for two-wheelers requires verification.

[0029] By verification it shall be prevented that the unauthorized removal of the vacuum is conducted, as such an unauthorized pressure equalisation would unintentionally remove the increased stability and the anti-theft protection of the kickstand for two-wheelers according to the invention or, respectively, of the attached two-wheeler.

[0030] According to the invention, pressure equalization means an adjustment of the pressure in the foot to the ambient pressure.

[0031] This verification is intended to ensure that only the authorized person(s) can initiate the pressure equalization and thus release the two-wheeler from the parking position. Such verification can be carried out, for example, analog or digital. Upon successful verification, for example, a valve may subsequently be opened or a valve opens and, as a result, ambient atmosphere flows into the at least one cavity of the foot and a pressure equalization takes place.

[0032] Examples of the analog verification comprise the use of a key or a numerical code. Examples of digital verification comprise the use of an app or a wireless remote control.

[0033] The use of an app means the digital verification by means of a program on a portable computer, such as a smartphone, which transmits a corresponding verification signal.

[0034] In particular, when an analog verification is used, a servomotor with a receiving device, for example an antenna, is preferably connected to a valve. In particular when two-wheelers with electrical components or a combustion engine are used, the energy required for this purpose can be obtained from these components. Alternatively and/or additionally and/or as a safeguard, for example, a battery can be used, which can be charged, for example, by pedaling the pedals during normal travel when a bicycle is used as a two-wheeler.

[0035] The analog verification is preferably carried out by means of a coded (radio) signal.

[0036] In a preferred embodiment, the verification takes place via an app by means of a mobile device signal, such as a smartphone.

[0037] In one embodiment, the kickstand for two-wheelers according to the invention has a device for the manual generation of the vacuum.

[0038] The manual generation of the vacuum can be carried out, for example, by means of a pressure-surface 7. In the parking mode, a force conducted on this pressure-surface 7 in the direction of the surface causes a contraction of the at least one cavity in the at least one foot 6 of the two-wheel stand. When this force is removed, the expansion of this at least one cavity takes place. If, for example, a correspondingly configured valve is connected to the foot, air can exhaust when contracting the cavity, but air cannot flow back when the cavity is expanding, resulting in a vacuum in the foot.

[0039] An integrated manual pump for generating a vacuum is also conceivable.

[0040] In one embodiment, the vacuum is generated automatically.

[0041] In addition, or as an alternative to the described manual vacuum generation, other methods for evacuation can also be used. For example, with an automated pump. In particular when two-wheelers with electrical components or a combustion engine are used, the automated pump can receive its energy from these components. As an alternative and/or additive and/or as a safeguard for such a pump, a battery can be used, for example. Such a battery can be charged, for example, by pedaling the pedals during normal travel when a bicycle is used as a two-wheeler.

[0042] The verification for the build-up of the vacuum can be carried out analogously to the verification described above for pressure equalization. Successful verification can, for example, close a valve, thereby preventing pressure equalization of any emerging or existing vacuum in the at least one cavity of the foot 6 with the environment.

[0043] This verification for the build-up of the vacuum is also preferably conducted via an app, which is implemented, for example, by means of a smartphone.

[0044] In one embodiment, the at least one foot 6 of the kickstand has at least two recesses.

[0045] Preferably, the foot is divided into at least one outer recess 10 and at least one inner recess 11, the at least one outer recess 10 preferably enclosing the at least one inner recess 11. Upon contact with a surface, at least one outer cavity and at least one inner cavity are then present, the at least one outer cavity preferably enclosing the at least one inner cavity.

[0046] The at least one outer cavity is preferably separated from the at least one inner cavity, or is only connected via a valve 12 or something similar. This valve 12 is designed in such a way that pressure equalization between the at least one outer cavity and the environment does not cause pressure equalization between this outer cavity and the at least one inner cavity, while evacuating the at least one inner cavity also evacuates the at least one outer cavity. Alternatively, the evacuation and/or the pressure equalization of the different cavities can also take place separately. FIG. 2 depicts a corresponding embodiment.

[0047] As a result of such a setup if, for example, the material in the region of the outer cavity and the environment is damaged or pressure equalization of the at least one outer cavity occurs due to another reason (for example, in the case of an attempted theft by trying to crack the cavity open) the other, i.e. internal cavities still maintain a vacuum.

[0048] If, for example, an unauthorized person damages the at least one outer cavity in order to force pressure equalization or attempts to lift the suction base 6 in order to equalize the pressure, this only results in pressure equalization of the at least one outer cavity and the vacuum in the further, i.e. inner cavities or unaffected outer cavities remains, whereby an unauthorized movement of the two-wheeler is furthermore prevented.

[0049] In an embodiment, the bicycle stand comprises at least one hollow duct, a receiving device for receiving a verification signal, a valve and a device for opening or closing the valve, wherein the at least one hollow duct connects the at least one recess of the foot to the environment and comprises the valve. The hollow duct, the receiving device for receiving a verification signal and the device for opening or closing the valve are preferably located on the foot (6), since such a construction is advantageous both structurally and statically.
