Description

The invention relates to a bicycle, bicycle or tricycle frame with at least one pipe section having at least one indentation or recess, which is intended to receive an inserted into the indentation or recess object, wherein the indentation or recess is formed as a cavity in the pipe section , which is closed on all sides with the exception of one to the outer circumference of the pipe section open or openable insertion.

Bicycles and optionally motorized bicycles are often equipped with tools and repair kit and with a bicycle pump. While the work and the repair kit is usually housed in frame pockets that stand out clearly from the bicycle and are also easily visible and accessible to unauthorized third parties, the bicycle pumps are releasably attached to the frame, where they complicate the handling of the wheel and can easily fall off.

E-bikes and pedelecs need a rechargeable battery as an electrical source of energy for the electric motor drive built into these two-wheelers. If necessary, this rechargeable battery is additionally detachably fastened to the frame or in the region of a rear luggage carrier, whereby additionally the external appearance of this bicycle can be impaired.

From the US Pat. No. 7,934,576 B2 One already knows a bicycle frame, which has at the top of its down tube oriented in the longitudinal extent of the down tube indentation, which is designed as a shape adapted to the complementary outer contour of a battery cross-sectional reduction. Since this indentation is designed as a cross-sectional reduction of the down tube, the previously known bicycle frame in this area is significantly weakened in its stability. In addition, the battery used in the indentation is clearly visible despite its complementary shape and also easily accessible to unauthorized third parties. In addition, due to the complementary shape of the indentation on the one hand and the battery on the other hand, the object is not freely selectable, which is to be housed in the region of the indentation of the known bicycle frame.

It has therefore already been created an electric vehicle with a bicycle frame, the seat tube, down tube or top tube is at least partially made of a hollow profile having a flat surface with an elongated recess for receiving the power supply unit intended for the electric drive (see. DE 20 2013 008 187 U1 ). In order to place the particular intended for receiving the power supply incision as easy as possible in the hollow profile, without having to provide additional lateral angle, and to avoid the incision incorporated into the hollow profile incision, is provided in the prior art electric vehicle that the elongated incision runs completely in the upper planar surface of the frame element, wherein the incision is to be completely surrounded by the flat surface. This is intended to accommodate the necessary energy storage for the electric drive of the bicycle on the bike without additional attachments while driving in the way. Due to the sinking of the energy storage in the bicycle frame should also be difficult to see from the outside, that in the previously known bicycle, a power supply unit is mounted.

From JP H09-66 876 A DE 20 2010 010 522 U1 already an electric bicycle with a bicycle frame of the type mentioned above is already known, which bicycle frame has a cross-sectionally U-shaped frame member having a recess integrally connected thereto, in which recess the power supply unit of the prior art electric bicycle is releasably applicable. In this case, the energy supply unit used in the recess fills the recess completely and further luggage is elsewhere stowed on the known bicycle or on the driver.

From the prior art, there is already known a two- or three-wheeled electric vehicle having a frame made of a sandwich structure made of urethane foam having a side insertion hole, into which insertion hole components of the electric drive such as an electric motor vehicle. the battery, a motor, a control unit or an AC / DC converter can be accommodated. For other luggage provided in this prior art electric vehicle insertion opening is not provided.

It is therefore an object to provide a bicycle, bicycle or tricycle frame of the type mentioned above, which allows the placement of a battery or the like energy storage, work and repair kit, a bicycle pump or other objects, without thereby affecting the handling of that Bicycle, two-wheeled or three-wheeled difficult, the appearance of which is impaired and unauthorized third parties are clearly encouraged to manipulate.

The solution to this problem is in the bicycle, bicycle or tricycle frame of the type mentioned in particular that the indentation or recess is divisible by means of at least one partition, which at least one partition in the indentation or recess releasably used and can be fixed in an insertion position.

Advantageous embodiments of the invention are characterized in the subclaims.

The bicycle, bicycle or tricycle frame according to the invention has at least one pipe section, which has at least one indentation or recess, which is intended to receive at least one object inserted into the indentation or recess.

According to the invention, provision is made for the at least one indentation or recess provided in the at least one pipe section to be formed as a cavity in the pipe section, which is closed on all sides, with the exception of an insertion opening open or openable towards the outer circumference of the pipe section. In the bicycle, bicycle or tricycle frame according to the invention, the indentation or recess provided in the at least one tube section is thus designed as a cavity, which is closed on all sides, with the exception of the insertion opening. In this cavity, the object to be stored can be used. Since this cavity is not formed as a cross-sectional reduction of the outer contour of the at least one pipe section, a sensitive weakening of the stability of the bicycle, bicycle or tricycle frame in the region of the at least one pipe section is avoided.

According to the invention, it is now provided that the indentation or recess can be subdivided by means of at least one partition wall, which at least one separating wall can be detachably inserted into the indentation or recess and can be fixed in the selected insertion position. Thus, the formed as a cavity indentation or recess in the at least one pipe section of the bicycle, bicycle or tricycle frame according to the invention are divided by at least one partition so that, for example, in a compartmentalized chamber this indentation or recess required as an energy source energy storage, such as a battery or a battery is housed, while in the other hand, other partitioned compartment of the indentation or recess, for example, the tool or repair kit needed for the repair case.

In this case, an embodiment according to the invention is preferred in which the indentation or recess is intended for the complete reception of at least one object used in the indentation or recess. Since the object in question thus disappears completely in the recess or recess formed as a cavity, an appealing appearance of the bicycle, bicycle or tricycle frame according to the invention is additionally favored.
