Description

[0001] The invention relates to a bicycle stand and a bicycle.

[0002] Jack stands are often used to park cargo bikes. Known jack stands, as described in EP2236396A1, for example, have a stand head that is connected to the bicycle and to which two stand legs, in particular interlocked for joint movement, are pivotally connected. To fold and unfold the stand legs, a pivot joint is connected to each stand leg, in particular in one piece, with the stand head, which pivotally supports the stand leg. The pivot joint has a joint socket, preferably designed in one piece with the stand head, with a, in particular trough-shaped, ceiling and two cheeks connected to the ceiling. A pivot pin is arranged between the two cheeks, over which the connected stand leg pivots under the ceiling and between the two cheeks.

[0003] Generally, to jack up the bike, the two feet of the bike stand are partially extended and brought into contact with the ground. Then, by moving the bike, the bike is jacked up onto the stand.

[0004] When jacking up, the kickstand leg folds out past the dead center, causing the kickstand legs to fall into an end position, particularly in a sudden, impulsive manner, against a stop. The stop is formed, in particular according to EP2236396A1, by the cover of the pivot joint. In other words, the two kickstand legs each strike the cover of the joint socket, particularly the tub-shaped wall of the cover. Due to the load from the weight of the bicycle, high forces occur at the stop.

[0005] In existing jack stands, damage and / or material failure of the stand head, particularly in the area of ​​the stop, have been observed, sometimes even after a small number of jacking cycles. A particular disadvantage of existing jack stands is their short service life.

[0006] The object of the invention is therefore to create a bicycle stand and a bicycle with an improved service life.

[0007] The object is achieved according to the invention by a bicycle stand according to claim 1, a bicycle stand according to claim 15 and a bicycle according to claim 18.

[0008] The bicycle stand according to the invention is, in particular, a jack stand. It is preferred that the preferably two-legged bicycle stand is a bicycle stand for a cargo bike. The bicycle stand has a stand head for connecting the bicycle stand to a bicycle frame, in particular to a down tube of the bicycle frame. The stand head comprises, in particular, metal, preferably aluminum, and is particularly made thereof. It is preferred that the stand head is a die-cast part. Furthermore, the bicycle stand has at least one stand leg. It is particularly preferred that the bicycle stand has two stand legs, arranged parallel to one another, in particular in the direction of travel. It is preferred that the two, in particular straight, stand legs extend diagonally outwards from the stand head.The bicycle stand has a pivot joint for each stand leg to pivotably connect the respective stand leg to the stand head. The pivot joint preferably has a degree of freedom of 1, preferably a rotational one. The pivot joint has a joint socket connected to the stand head, in particular in one piece. The joint socket is preferably manufactured integrally with the stand head, preferably by primary molding, particularly preferably by die casting. The joint socket has a, in particular trough-shaped, ceiling and two cheeks connected to the ceiling. It is preferred that the joint socket has a dome shape. The dome shape is formed in particular by the ceiling and the two cheeks, wherein it is preferred that the ceiling has a curve and that the two cheeks, each formed by a wall, extend from the ceiling on both sides, preferably perpendicularly from a base area of ​​the ceiling.The support leg is pivotally connected to the joint socket between the two cheeks. In this case, it is preferred that the support leg, in particular a head element of the support leg, is pivotable below the ceiling, particularly preferably within the joint socket, e.g. within the dome shape of the joint socket. Pivotable means in particular a foldable design, wherein the support leg is pivotable between a folded position, preferably a travel position, into an unfolded position, preferably a standing position, particularly preferably a jacked-up position. The support leg, preferably the head element of the support leg, is pivotally mounted in the joint socket. The support head has a stop for the support leg in a folded-out position.The stop is preferably connected to at least one of the cheeks, in particular to both cheeks, in such a way that a stop force is absorbed, preferably directly, by the at least one cheek. It is preferred that the stop force is absorbed largely, preferably completely, by at least one of the cheeks, in particular both cheeks. The stop force is in particular a force that acts on the stop from the stand leg when it reaches the unfolded position. In particular, the stop force is a stop impulse. The two cheeks are in particular parallel to one another. The stand legs in particular comprise metal, for example aluminum or steel, and are in particular made thereof.

[0009] In a preferred embodiment, the stop is spaced from the ceiling. The ceiling is, in particular, stop-free, in other words, it has no stop. The stop is, in particular, connected to the cheeks, preferably directly. It is preferred that the stop is not connected directly, and thus in particular only indirectly, to the ceiling, e.g. via the cheeks. In particular, the stop has a distance from the ceiling of at least 0.5 mm, preferably at least 1 mm, particularly preferably at least 5 mm. Due to the distance of the stop from the ceiling and / or the force absorption by the at least one cheek, notch effects are reduced or prevented, for example compared to existing bicycle racks, with regard to the stop force, in particular since radii during the application of force are reduced or prevented.

[0010] In a preferred embodiment, the column head has a stop pin for forming the stop. The stop pin has, in particular, a round, e.g., circular, or rectangular, e.g., square, cross-section. The stop pin is, in particular, a steel pin.

[0011] In a preferred embodiment, the stop pin is arranged between the cheeks. It is preferred that the stop pin is connected to both cheeks. In a preferred embodiment, one of the cheeks, in particular both cheeks, has a bore for receiving the stop pin. The stop pin can be inserted into the cheeks and / or removed, preferably pulled out.

[0012] In a preferred embodiment, the stop pin is connected to the cheeks by means of a fit. It is preferred that the fit between the stop pin and the bore in the cheek is implemented. In particular, the stop pin is connected to one of the cheeks with a transition fit and / or to the other cheek with a press fit. It is preferred, particularly in the embodiment in which the two upright legs run diagonally outwards starting from the upright head, that the connection between the stop pin and cheek on the inward-facing cheek is made via a press fit and / or that the connection between the stop pin and cheek on the outward-facing cheek is made via a transition fit. Alternatively or additionally, the stop pin is connected to one or both cheeks by means of a screw connection. In particular, the stop pin is connected to the outward-facing cheek by means of a screw connection. E.g.the pin has, at least partially, an external thread and / or one or both cheeks, preferably the outward-facing cheek, an internal thread.

[0013] In a preferred embodiment, the column leg has a column stop that engages the stop. The column stop is particularly designed as a single piece with the column leg, preferably manufactured together with it, e.g., by primary molding.
