[0001] DE 20 2019 104 857 U1 describes a holding device for a display device of a two-wheeler. Disclosure of the invention

[0002] The invention relates to a connecting device for the force-locking and form-locking connection of a first detachable bicycle component to a second bicycle component, comprising a first rigid connecting unit and a second movable connecting unit, wherein the rigid connecting unit has at least two connecting elements which extend towards one another from a base body of the rigid connecting unit and form a receiving space for receiving the second movable connecting unit, wherein the movable connecting unit has at least one movable locking element. It is proposed that the rigid connecting unit has at least one securing element which is designed to block or guide a relative movement of the rigid connecting unit to the movable connecting unit depending on the direction and / or location of a force acting on the first detachable bicycle component.This advantageously ensures a robust connection between the second bicycle component and the first bicycle component, thus preventing unintentional loosening of the bicycle components.

[0003] In the context of this application, a detachable bicycle component is understood to mean, in particular, a bicycle component that can be removed without tools and without causing damage. The first bicycle component can be, for example, a display device, a holder for a smartphone, an on-board computer, a drinking bottle, a holder for a drinking bottle, a lighting unit, a bicycle lock, a battery pack for supplying power to the bicycle, or the like for a bicycle.

[0004] The second bicycle component is preferably designed as a holding device for the first bicycle component. The second bicycle component can be permanently connected to the bicycle or detachably connected to the bicycle. In particular, the second bicycle component is designed such that it can be connected to the bicycle using a tool, for example, via a screw connection. It is also conceivable for the second bicycle component to be integrated into a component of the bicycle, for example, into the bicycle frame.

[0005] Alternatively, it is also conceivable that the connecting device is designed for further components, for example for hand tool machine components or household appliance components.

[0006] A rigid connecting unit is to be understood in particular as a connecting unit which is only movable as a whole during the connecting process and in which the connecting elements assigned to the rigid connecting unit essentially do not perform any relative movement to one another.

[0007] A movable connecting unit is understood, in particular, to be a connecting unit whose connecting elements undergo a relative movement with one another during the connection process. For this purpose, the movable connecting unit has at least one movable locking element that is mounted for linear and / or rotational movement. Alternatively or additionally, it is also conceivable for the relative movement to occur through a plastic or elastic deformation of the movable locking element.

[0008] The securing element can be formed as a single piece or integrally with the rigid connecting unit. In the context of this application, "single piece" is understood to mean, in particular, that the components are manufactured from a single part and are not connected to one another by force, form, and / or material fit. Components formed as a single piece are thus at least partially or entirely made of the same material. The securing element can have a reinforcing element, which is made of metal, for example. Alternatively or additionally, it is also conceivable for the securing element to be partially or completely elastic or plastic to absorb forces. The connecting device can have one or more securing elements.The securing element is preferably designed such that, depending on the location and direction of the force, the relative movement is blocked only up to a threshold value of the force, wherein the connection is released when the force is exceeded.

[0009] The bicycle components can be intended for a bicycle and in particular for an electric bicycle. In the context of this application, an electric bicycle is understood to mean, in particular, a bicycle that has a drive unit for assisting the rider. The electric bicycle is preferably designed as an eBike, a Pedelec, an S-Pedelec, a cargo bike, a folding bicycle, or the like. The drive unit has a motor, which can be designed, for example, as a mid-engine or as a hub motor. The motor is preferably designed as an electric motor. The drive unit is connected to the battery pack for supplying the drive unit with energy. The housing of the battery pack is preferably designed to be detachably connectable to the electric bicycle, in particular to a frame of the electric bicycle. The electric bicycle comprises electronics with a control device for controlling or regulating the electric bicycle.The electronics preferably comprise a sensor unit, which may include, for example, motion sensors, torque sensors, speed sensors, a GNSS receiver, magnetic sensors, or the like. Furthermore, the electronics preferably comprise a communication interface for wirelessly connecting the electric bicycle to an external device, such as a smartphone, and / or a server.

[0010] Furthermore, it is proposed that the at least one securing element be arranged outside the receiving space. This can advantageously increase the effectiveness of the securing element. Alternatively, it is also conceivable for the securing element to be arranged in the receiving space, in particular in an area of ​​electrical contact elements of the respective bicycle components.

[0011] It is further proposed that the securing element have an insertion bevel facing the receiving space. This advantageously simplifies the connection process when the user intentionally connects or disconnects the element.

[0012] It is further proposed that the securing element be designed at a distance from the bicycle component in the locked state. This advantageously allows the connection process to be further optimized ergonomically. The bicycle component, in particular, has a stop against which the securing element strikes the bicycle component depending on the direction and location of the force acting on it, blocking further relative movement. The distance between the securing component and the stop is preferably at least 10%, more preferably at least 20%, of the unlocking distance required to release the connection between the bicycle components.

[0013] It is also proposed that the rigid connecting unit be formed in one piece. This advantageously ensures a high degree of robustness of the rigid connecting unit. The rigid connecting unit is preferably made of a plastic, in particular a hard plastic.

[0014] Furthermore, it is proposed that the movable locking element be rotatably mounted. This advantageously allows for a compact design of the movable connecting unit.

[0015] It is further proposed that the movable locking element be pre-tensioned, in particular pre-tensioned by a spring force. This advantageously ensures secure fixation of the first detachable bicycle component in the second bicycle component. The movable locking element can be subjected to a force directly or indirectly by a spring element. The spring element can be formed from a metal spring or a plastic spring. The spring element can be formed, for example, as an annular spring, a spiral spring, or a leg spring. It is also conceivable for the spring element to be formed from an elastic plastic.

[0016] It is also proposed that the movable locking element have a connecting element receiving space configured to allow linear movement of the connecting element within the movable, in particular rotatable, locking element. This advantageously allows for a particularly convenient actuation mechanism for the user. For this purpose, the connection receptacle preferably has a width that is at least 15%, in particular at least 25%, greater than the width of the corresponding connecting element of the rigid connecting unit.

[0017] It is further proposed that the first detachable bicycle component be designed as a display device. The display device has at least one display element for displaying information. The display element can be designed as a light element, for example as an LED, or as a screen for displaying numerical and / or graphic symbols.

[0018] It is also proposed that the second bicycle component be designed as a holding device. The holding device preferably has a bicycle interface for mounting the second bicycle component on the handlebars or frame of the bicycle.

[0019] Alternatively, the invention relates in particular to a connecting device for the force-locking and form-locking connection of a first detachable bicycle component to a second bicycle component, comprising a first rigid connecting unit and a second movable connecting unit, wherein the rigid connecting unit has at least one connecting element, wherein the movable connecting unit has at least one rotationally movable locking element. It is proposed that the connecting element of the first connecting unit has an undercut element which corresponds to an undercut element of the locking element of the second connecting unit, wherein the undercut elements act at least partially counter to an unlocking direction. This advantageously allows the release characteristic to be optimized. The undercut elements are preferably hook-shaped.

[0020] An unlocking direction is understood to mean a direction or a direction of movement of the first bicycle component relative to the second bicycle component, which the first bicycle component passes through or must pass through to unlock or release the connection. The unlocking direction can have one or more movement components, wherein the movement components can be linear or rotational. The unlocking movement can, for example, be implemented in two stages, wherein in a first stage, a substantially linear movement in the unlocking direction is performed, and in a second stage, the locking is released via a rotational movement.

[0021] The connecting device is particularly designed such that unlocking occurs without the user having to actuate an actuating element, such as a button. Alternatively, it is also conceivable for the connecting device to have such an actuating element and for unlocking to occur via a single-step movement.

[0022] Furthermore, it is proposed that the at least one undercut element of the connecting element extends inwards or outwards from a base surface which is arranged on a side facing the locking element.

[0023] Furthermore, it is proposed that the at least one undercut element of the locking element extends outwards or inwards from a base surface which is arranged on a side facing the connecting element.

[0024] It is also proposed that the undercut element be arranged laterally spaced from an edge of the connecting element or the locking element across the base surface. The combination of the base surface with the undercut element can advantageously ensure the compatibility of different rigid connecting units with the same movable connecting unit.

[0025] Furthermore, it is proposed that the connecting element and the locking element each have at least two undercut elements. This advantageously further improves compatibility. In particular, the at least two undercut elements are spaced apart from one another over a portion of the base surface.

[0026] It is further proposed that the rigid connecting element have at least one securing element arranged on a side of the rigid connecting element opposite the at least one undercut element, wherein the securing element and the undercut element extend in opposite directions. This can advantageously increase the robustness of the connecting device.

[0027] It is also proposed that at least one undercut element of the rigid connecting element has an insertion bevel. This advantageously optimizes the connection process for the user.

[0028] Furthermore, it is proposed that the undercut element have an undercut region that extends in an angular range between 10° and 40°, preferably 20° and 30°, relative to the unlocking direction. This advantageously allows the connection process to be further optimized.

[0029] Furthermore, it is proposed that the undercut area and the lead-in slope be connected via a curved connecting area. This can advantageously optimize the release process.

[0030] It is also proposed that the undercut elements be designed such that, when a force is applied substantially perpendicular to the unlocking direction, unlocking occurs at a force of at least 50 N, preferably at least 90 N. This advantageously prevents at least some damage to the connecting device, in particular to the rigid connecting unit or the movable connecting unit. The undercut elements thus advantageously provide overload protection.

[0031] Furthermore, it is proposed that the first detachable bicycle component is designed as a display device and / or that the second bicycle component is designed as a holding device.

[0032] Furthermore, the invention relates to a holding device with a movable connecting unit as described above. Alternatively, it is also conceivable for the holding device to comprise the rigid connecting unit.

[0033] Furthermore, the invention relates to a display device with a rigid connecting unit as described above. Alternatively, it is also conceivable for the display device to comprise the movable connecting unit. Drawings

Description of the embodiments

[0036] In Fig. Figure 1 shows a side view of a bicycle 10, in particular an electric bicycle 12 with an energy storage device 14 in the form of a battery pack 16. The electric bicycle 12 can be designed, for example, as a pedelec or as an e-bike. The electric bicycle 12 comprises a connecting device 100, which is designed to connect a first detachable bicycle component 102 to a second detachable bicycle component 104 (see Figure 1). Fig. 3).

[0037] The electric bicycle 12 has a housing in the form of a frame 20 or a bicycle frame. Two wheels 22 are connected to the frame 20. The electric bicycle 12 also has a drive unit 26, which comprises an electric motor or an auxiliary motor. The electric motor is preferably designed as a permanent magnet-excited, brushless DC motor. The electric motor is designed, for example, as a mid-mounted motor, although a hub motor or the like is also conceivable. The electric bicycle 12, in particular the drive unit 26 of the electric bicycle 12, is supplied with energy via the battery pack 16. The battery pack 16 is connected to the electric bicycle 12, in particular to the frame 20 of the electric bicycle 12, by means of a battery pack connecting device 25. The connection is made, for example, by means of a pivoting movement.

[0038] The electric bicycle 12 includes a control unit (not shown in detail), which is assigned, for example, to the drive unit 26 and designed to control or regulate the electric bicycle 12. The control or regulation is not limited to the drive of the motor, but also includes the connection or communication to the battery pack 16 and other bicycle components of the electric bicycle 12, for example, a front light 40 and a display device 30. The display device 30 is designed to be connectable to the electric bicycle 12 without the need for tools and, for example, forms the first bicycle component 102.

[0039] The control unit of the electric bicycle 12 has a sensor unit. The sensor unit of the electric bicycle 12 includes, for example, several sensor elements, such as a torque sensor, a motion sensor, for example in the form of a three-axis acceleration sensor, and a magnetic sensor.

[0040] The control unit and the drive unit 26 with the electric motor and the pedal crankshaft are arranged in a drive housing 27 connected to the frame 20. The electric bicycle 12 has a pedal crank 28. The pedal crank 28 has a pedal crankshaft (not shown). The drive movement of the electric motor is preferably transmitted to the pedal crankshaft via a gear (not shown), wherein the amount of assistance provided by the drive unit 26 is controlled or regulated by the control unit. The control unit is designed to actuate the drive unit 26 such that the rider of the electric bicycle 12 is assisted while pedaling. The control unit is preferably designed to be operable by the rider so that the rider can adjust the level of assistance. The adjustment can be made, for example, via the display device 30 and / or an external device (not shown), such as a smartphone.

[0041] The control unit and the sensor unit are assigned to an electronics unit (not shown), which, for example, has a circuit board on which a computing unit in the form of a CPU, a memory unit, and the sensor unit. The electronics unit can be arranged essentially entirely in the region of the drive unit. However, it is also conceivable for the electronics unit of the electric bicycle 12 to be arranged entirely or partially in the region of another bicycle component. For example, it would also be conceivable for the display device 30 to be designed as an on-board computer and additionally comprise the control unit for controlling the electric bicycle 12. In this case, however, the electric bicycle 12 would only be usable when connected to the on-board computer.

[0042] The display device 30 is, for example, detachably attached to a handlebar 32 of the electric bicycle 12. The display device 30 is designed to display information. The display device 30 also comprises at least one operating element (not shown) via which the user or rider can control the display device 30 and / or the electric bicycle 12. The operating element is, for example, designed as a touch-sensitive screen. The display device 30 is connected to the control unit of the electric bicycle 12 such that information can be exchanged. For example, a speed determined by the control unit, a set level of assistance of the electric motor, route information from a navigation unit, and a charge level of the battery pack 16 can be displayed via the display device 30.

[0043] In Fig. 2 shows a side view of the first bicycle component 102 in the form of the display device 30 in the state connected to the second bicycle component 104 in the form of a holding device 106. The connection is made via the connecting device 100, which comprises a rigid connecting unit 108 and a movable connecting unit 110 (see Fig. 3).

[0044] The display device 30 is designed to be detachable from the holding device 106 without the need for tools. The connecting device 100 is preferably designed such that both connection and detachment can be performed using one-handed operation. The display device 30, for example, has the rigid connecting unit 108 of the connecting device 100.

[0045] The holding device 106 is designed for mounting on the electric bicycle 12. For this purpose, the holding device 106 has a mounting unit 112, which is designed, for example, in the shape of a clamp and can be fixed to the electric bicycle 12, in particular to the handlebar 32 of the electric bicycle 12, by means of a screw connection 117 using a tool. The mounting unit 112 is designed to be particularly flexible so that it can be fixed to different handlebars with different diameters. Furthermore, the holding device 106 has the movable connecting unit 110, which corresponds to the rigid connecting unit 108 of the display device 30.

[0046] In Fig. 3 shows a longitudinal section through the two bicycle components 102, 104, in particular through the rigid connecting unit 108 of the display device 30 and the movable connecting unit 110 of the holding device 106.

[0047] To connect the two bicycle components 102, 104, the first bicycle component 102 is pushed onto the second bicycle component 104 essentially linearly along a first connecting direction 112 via a first connecting movement, and then a pivoting movement of the first bicycle component 102 for engagement with the second bicycle component 104 takes place via a second connecting movement.

[0048] The rigid connecting unit 108 of the display device 30 has, for example, two connecting elements 114, a first connecting element 113 and a second connecting element 115, which extend toward one another from a base body 116 of the rigid connecting unit 108. The connecting elements 114 are, in particular, substantially rigid. The first connecting element 113 of the rigid connecting unit 108 and the second connecting element 115 of the rigid connecting unit 108 are, in particular, arranged on different sides of the movable connecting unit 110. The rigid connecting unit 108 can each have one or more first and / or second connecting elements 113, 115.

[0049] The base body 116, viewed in cross-section, is essentially U-shaped, for example, and defines a receiving space designed to receive the movable connecting unit 110. The rigid connecting unit 108 is, for example, formed in one piece. The rigid connecting unit 108 is formed on an outer side of a housing 118 of the display device 30. The housing 118 of the display device 30 comprises, for example, two housing parts 120 designed as housing half-shells, wherein the rigid connecting unit 108 is, for example, formed in one piece with one of the housing parts 120. The connecting elements 114 of the rigid connecting unit are firmly connected to one another in such a way that they do not move relative to one another during the connecting or disconnecting process.

[0050] The movable connection unit 110 has two connecting elements 122, a first connecting element 121 and a second connecting element 123, which correspond to the connecting elements 114 of the rigid connection unit 108. The movable connection unit 110 can each have one or more first and / or second connecting elements 121, 123.

[0051] The first connecting element 121 of the movable connecting unit 110 is substantially rigid and forms a receptacle for engagement of the first connecting element 113 of the rigid connecting unit.

[0052] The second connecting element 123 of the movable connecting unit 110 is designed as a movable locking element 126. The second connecting element 123 is movably mounted in the holding device 106. In particular, the second connecting element 123 of the movable connecting unit 110 is mounted for rotational movement about a rotation axis 128. The second connecting element 123 of the movable connecting unit 110 is also connected to a reset element 130 such that the reset element 130 applies a force to the movable locking element 126 toward the locked state. The reset element 130 is designed, for example, as a spring element in the form of a spiral spring.

[0053] In the connected state, the connecting elements 122 of the movable connecting unit 110 are connected to the connecting elements 114 of the rigid connecting unit 108, for example, via a positive connection.

[0054] To release the connection, the second connecting element 115 of the rigid connecting unit 108 is pressed against the movable locking element 126 of the movable connecting unit 110 by applying force to the first bicycle component 102 in the direction of the unlocking direction 111, which corresponds to the first connecting direction 112. As a result, the movable locking element 126 is pivoted about the rotation axis 128 against the restoring force of the spring element 130. In particular, the second connecting element 123 of the movable connecting unit 108 moves toward the first connecting element 121 of the movable connecting unit 108, thereby shortening the distance and moving the connecting elements 122 of the movable connecting unit 110 relative to one another.

[0055] While the second connecting element 123 of the movable connecting unit 110 pivots, the movement of the first bicycle component 102, in particular the second connecting element 115 of the rigid connecting unit 108, is essentially linear. For this purpose, the movable locking element 126 has a connecting element receiving space 132 for the second connecting element 115 of the rigid connecting unit 108, which is at least 10%, preferably at least 25%, wider than the corresponding connecting element 115 to be received. In contrast, the first connecting element 121 of the movable connecting unit 110 has a connecting element receptacle 134, the width of which is essentially adapted to the width of the corresponding first connecting element 113 of the rigid connecting unit 108, thereby implementing essentially linear guidance in this area.

[0056] The movement of the first bicycle component 102 along the unlocking direction 111 continues until the first connecting element 113 of the rigid connecting unit 108 is no longer engaged with the first connecting element 121 of the movable connecting unit 110 or is no longer arranged in the connecting element receptacle 134. To release the connection, the positive locking is released by means of a pivoting movement, so that the first bicycle component 102 can be removed from the second bicycle component 104.

[0057] The connecting device 100 is designed such that unlocking can occur even if a force is applied to the bicycle component whose direction does not completely correspond to the unlocking direction 111. This has the advantage for the user that the connection can be made and released more easily.

[0058] However, to ensure that the connection is not accidentally released, the connecting device 100 has a securing element 140. The securing element 140 is designed, in particular, to block or guide a relative movement of the rigid connecting unit 108 to the movable connecting unit 110, depending on the direction and / or location of a force acting on the first detachable bicycle component 102.

[0059] The securing element 140 is, for example, assigned to the rigid connecting unit 108. For example, the securing element 140 is arranged in the region of the second connecting element 115 of the rigid connecting unit 108. In particular, the securing element 140 is arranged on a side facing away from the second connecting element 115 of the rigid connecting unit 108 on the base body 116 of the rigid connecting unit 108. The securing element 140 is, for example, nose-shaped. Fig. In the locked or connected state depicted in Figure 3, the securing element 140 is arranged at a distance from the second bicycle component 104, in particular from the movable connecting unit 110. The distance is preferably at least 10%, preferably at least 25%, of the path in the unlocking direction 111 for releasing the positive engagement of the mutually corresponding first connecting elements 113, 121.

[0060] The securing element 140 is arranged and designed in such a way that upon the action of a first force 142, which has a portion in the direction of the unlocking direction 111, but also a high portion perpendicular to the unlocking direction 111, the securing element 140 strikes an outer surface 144 of the second bicycle components 104, in particular a stop element 151 of the connecting device 100 provided for this purpose, and comes to rest, as in Fig. 4. This advantageously effectively prevents unlocking of the first bicycle component 102 when the first force 142 is applied. The movable locking element 126 is pivoted only within an insignificant range. The first force 142 is directed in particular such that the first bicycle component 102 is essentially pressed onto the second bicycle component 104. Alternatively or additionally, the first force 142 can also be described as an impact from above on the first bicycle component 102, acting in the direction of the handlebar 32. The further away the first force 142 acts on the housing of the first bicycle component 102 relative to the second connecting element 115, the greater the leverage effect. For this reason, a different size of the first bicycle component 102 may also require adaptations to the securing element 140, or the securing element 140 may be omitted in the case of smaller housings.

[0061] In addition to the blocking function in the event of an undesired force being applied, the securing element 140 also has a guiding function if a force acts on the first bicycle component 102 essentially entirely in the direction of the unlocking direction 111.

[0062] For this purpose, the securing element 140 has an insertion bevel 146 that faces the receiving space of the rigid connecting unit 108. In particular, the insertion bevel 146 of the securing element 140 faces the second bicycle component 104 in the connected state. The insertion bevel 146 is formed obliquely to the unlocking direction 111; the insertion bevel 140 preferably has an angle of between 20° and 70°, more preferably an angle of between 30° and 60°, relative to the unlocking direction 111.

[0063] Due to the force applied in the unlocking direction 111, the securing element 140 with the insertion bevel 146 comes into contact with the outside of the second bicycle component 104. Due to the oblique design of the insertion bevel 146, a further force applied in the unlocking direction 111 guides the securing element 140, in that the second connecting element 115 of the rigid connecting unit 108 of the first bicycle component 102 is pushed away from the second bicycle component 104 by a height 141 of the securing element 140, as shown in Fig. 5. Advantageously, the positive locking of the corresponding first connecting elements 113, 121 can subsequently be released by the pivoting movement.

[0064] Also in Fig. 5 shows electrical contact pins 145 designed to electrically connect the first bicycle component 102 to the second bicycle component 104. The electrical connection can be used to supply power to the first bicycle component 102 via the second bicycle component 104 or to exchange information between the bicycle components 102, 104. The contact pins 145 are, for example, spring-mounted, so that the contact pins 145 are always pressed against corresponding contact elements (not shown) of the first bicycle component 102 by means of a contact force.

[0065] In Fig. 5a shows an alternative embodiment of the connecting device 100a, wherein the first and second bicycle components 102a, 104a substantially correspond to the previously described bicycle components 102, 104, but differ in the design of the securing element 140a.

[0066] The securing element 140a is arranged, for example, in the region of the first connecting elements 113a, 121a. In particular, the securing element 140a is designed as a lug 148a, which is arranged on the first connecting element 113a of the rigid connecting unit 108a and protrudes into the connecting element receptacle 134a. The first connecting element 113a of the rigid connecting unit 108a has a pocket 150a corresponding to the securing element 140a.

[0067] In Fig. 5b shows a further alternative embodiment of the connecting device 100b, wherein the first and second bicycle components 102b, 104b substantially correspond to the previously described bicycle components 102, 104, but the design of the securing element 140b differs.

[0068] The securing element 140b is arranged in a region of the second connecting elements 123b, 115b. The securing element 140b is designed, for example, as a user-movable securing element 140b, which is clamped by pressing after the bicycle components 102b, 104b are connected between the first bicycle component 102b and the second bicycle component 104.

[0069] For this purpose, the securing element 140b can be connected to the housing of the first bicycle component 102b, for example, via a joint or a hinge. Alternatively, it is also conceivable for the securing element 140b to be formed integrally with one of the housing parts 120b and to be elastic due to its shape, for example, as a thin clip as schematically shown, which is slightly bent for securing.

[0070] In Fig. 5c shows a further alternative embodiment of the connecting device 100c, wherein the first and second bicycle components 102c, 104c substantially correspond to the previously described bicycle components 102, 104, but the design of the securing element 140c differs.

[0071] The connecting device 100c has, for example, two securing elements 140c formed in the region of the contact pins 145c of the second bicycle component 104c. The contact pins 145c emerge from the second bicycle component 104c in the region of an outlet opening 149c, with the securing element 140c being formed by a collar-shaped configuration of the outlet opening 149c. The contact elements 153c of the first bicycle component 102c corresponding to the contact pins 145c are arranged offset inward in receiving pockets 147c that correspond to the securing elements 140c.

[0072] The securing elements 140c and receiving pockets 147c are designed in such a way that when a force is applied analogous to the force 142 in Fig. 3 an unlocking is blocked and in the case of a force in the unlocking direction 111c a guidance is carried out by the securing element 140c, in particular by the insertion bevel 146c of the securing element 140c.

[0073] In addition to the securing element 140 for preventing an unintentional release of the connection by the first force 142 from above or from obliquely above, the connecting device 100 has Fig. 3 has two mutually corresponding undercut elements 160, 162, which act at least partially counter to the unlocking direction 111. The undercut elements 160, 162 are arranged in the region of the movable locking element 126 of the movable connecting unit 110.

[0074] The rigid connecting unit 108 has, for example, two first undercut elements 160 and the movable connecting unit has, for example, two second undercut elements 162.

[0075] The first undercut elements 160 of the rigid connecting unit 108 are arranged on the second connecting element 115 of the rigid connecting unit 108 and in Fig. 6 in a side view and in Fig. 7 in a perspective view. The first undercut elements 160 are arranged on a side associated with the second connecting element 123, in particular the movable locking element 126.

[0076] The first undercut elements 160 extend outwardly from a base surface 166, which is arranged on a side facing the movable locking element 126. The two undercut elements 160 are separated from each other by a section with the base surface 166 and are spaced from the edge of the second connecting element 115 of the rigid connecting unit 108 by a section with the base surface 166.

[0077] The undercut elements 160 have an insertion bevel 168 directed forward in the unlocking direction 111. In contrast, the undercut elements 160 opposite the unlocking direction 111 each have at least one undercut region 170. The undercut region 170 is provided to form the undercut and, in the connected state, rests completely or at least partially against the corresponding undercut element 162 of the movable connecting unit 110. The undercut region 170 is formed by a substantially planar surface that extends at an angle of approximately 45° relative to the unlocking direction 111. In particular, the undercut region 170 has a flatter acute angle to the unlocking direction 111 than the insertion bevel 168.

[0078] The undercut region 170 and the insertion bevel 168 are connected to each other via a curved connecting region 172 which extends in the direction of the corresponding connecting element 115.

[0079] In Fig. 8 shows the movable locking element 126 in a perspective view, wherein the movable locking element 126 has two corresponding second undercut elements 162. The two second undercut elements 162 extend inwardly from a base surface 174. In particular, the second undercut elements 162 extend away from the second connecting element 115 of the rigid connecting unit 108.

[0080] By combining the undercut elements 160, 162 with the respective base surfaces 166, 174, the mechanism can be designed such that the movable connecting unit 110 is also compatible with an alternative, not-shown, rigid connecting unit that does not have additional undercut elements 160. This can be advantageous, for example, for first bicycle components that are so compact that no second force 143 can be applied to them from below because this direction is essentially covered by the second bicycle component 104.

[0081] The undercut elements 160, 162 are provided, in particular, to prevent the first bicycle component 102 from detaching from the second bicycle component 104 when a second force 143 acts on the first bicycle component 102. The second force 143 is applied transversely, in particular substantially perpendicularly, to the unlocking direction 111 and is directed away from the first bicycle component 102. The second force 143 acts, in particular, on the first bicycle component 102 when it is impacted from below. This can occur unintentionally by the user or as a result of a fall.

[0082] In Fig. 9, the bicycle components 102, 104 are shown in the event of such an unintentional impact from below, in which a second force 143 acts on the first bicycle component 102.

[0083] The second force 143 pushes the first bicycle component 102, in particular the second connecting element 115 of the rigid connecting unit 108, away from the second bicycle component 104 and moves upwards in the depicted view. Through the connection of the second connecting element 115 of the rigid connecting unit 108 to the movable locking element 126 of the movable connecting unit 110, the second force 143 is partially transferred to the movable locking element 126, which thereby pivots against the spring force and entrains the second connecting element 115 of the rigid connecting unit 108 due to the undercut elements 160, 162, whereby the connection is initially maintained, as shown in Fig.9. The connecting device 100, in particular the undercut elements 160, 162, are designed such that when a force is applied perpendicular to the unlocking direction 111 by the second force 143, unlocking occurs from a second force 143 of at least 50 N, preferably at least 90 N, and thus the engagement of the second connecting element 115 in the movable locking element 126 is released.

[0084] Thus, the connecting device 100 is designed such that the positive connection between the bicycle components 102, 104 can be released depending on the force applied in the region of the first connecting elements 113, 121 or in the region of the second connecting elements 115, 123. In particular, upon an intended force applied along the unlocking direction 111 or an unintentional first force 142, the connection is initially released in the region of the first connecting elements 113, 121, and upon the application of an unintentional force 143, the connection is initially released in the region of the second connecting elements 115, 123.
