[0001] The invention relates to a connecting device for connecting a first detachable bicycle part to a second bicycle part in a force-fitting and form-fitting manner. The invention also relates to a holding device and a display device. Background Art

[0002] A holding device for a display device of a two-wheeled vehicle is described in patent document DE 20 2019 104 857 U1. Summary of the invention

[0003] The invention relates to a connecting device for connecting a first releasable bicycle part to a second bicycle part in a force-locking and form-locking manner, the connecting device having a first rigid connecting unit and a second movable connecting unit, wherein the rigid connecting unit has at least two connecting elements, which extend from a base of the rigid connecting unit toward each other and form a receiving space for receiving the movable second 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 prevent or guide a relative movement of the rigid connecting unit relative to the movable connecting unit, depending on the direction and / or position of the force acting on the first releasable bicycle part. Advantageously, a stable connection between the second bicycle part and the first bicycle part can be ensured thereby, thereby preventing an accidental release of the bicycle parts.

[0004] In the context of the present application, a releasable bicycle component is to be understood in particular as a bicycle component which is designed to be releasable without tools and without destruction. The first bicycle component is, for example, a display device, a holder for a smartphone, an onboard computer, a water bottle, a holder for a water bottle, a lighting unit, a bicycle lock, a battery pack for the energy supply of a bicycle or the like for a bicycle.

[0005] The second bicycle component is preferably designed as a holding device for the first bicycle component. The second bicycle component can be designed to be firmly connected to the bicycle or to be releasably connected to the bicycle. The second bicycle component is particularly designed so that it can be connected to the bicycle with the help of a tool, for example by screwing. It is also conceivable that the second bicycle component is designed to be integrated in a component of the bicycle, for example in the frame of the bicycle.

[0006] Alternatively, it is also conceivable that the connecting device is designed for other components, for example for a handheld power tool component or a domestic appliance component.

[0007] In this case, a rigid connecting unit is to be understood in particular to mean a connecting unit which, during the connecting process, can only be moved as a whole and in which connecting elements assigned to the rigid connecting unit substantially do not perform relative movements relative to one another.

[0008] In this context, a movable connecting unit is to be understood in particular as a connecting unit whose connecting elements perform a relative movement relative to one another during the connecting process. For this purpose, the movable connecting unit has at least one movable locking element which is supported so as to be linearly and / or rotationally movable. Alternatively or additionally, it is also conceivable that the relative movement takes place by plastic or elastic deformation of the movable locking element.

[0009] The safety element can be constructed integrally or in one piece with the rigid connection unit. "One-piece" in conjunction with the context of the present application should be understood in particular as meaning that the components are made of one part and are not connected to each other in a force-locking, form-locking and / or material-locking manner. The components constructed in one piece are therefore at least partially or completely constructed of the same material. The safety element can have a reinforcing element, for example, made of metal. Alternatively or additionally, it is also conceivable that the safety element is partially or completely elastically or plastically constructed to accommodate forces. The connecting device can have one or more safety elements. The safety element is preferably constructed in such a way that relative movement is prevented depending on the position and direction of the force action until a threshold value of the force is reached, wherein, when the force is exceeded, the connection is loosened.

[0010] Here, the bicycle component can be provided for a bicycle and in particular for an electric bicycle. An electric bicycle in conjunction with the context of the present application should be understood as a bicycle having a drive unit for assisting a rider. The electric bicycle is preferably configured as an electric bicycle (eBike), an electric assisted bicycle (Pedelec), a high-speed electric assisted bicycle (S-Pedelec), a cargo bicycle, a folding bicycle or the like. The drive unit has a motor, which can be configured as a mid-mounted motor or a hub motor, for example. The motor is preferably configured as an electric motor. The drive unit is connected to a battery pack for supplying energy to the drive unit. The housing of the battery pack is preferably configured to be releasably connected to an electric bicycle, in particular to a frame of an electric bicycle. The electric bicycle includes an electronic device having a control device for controlling or regulating the electric bicycle. The electronic device preferably includes a sensor unit, wherein the sensor unit can, for example, include a motion sensor, a torque sensor, a speed sensor, a GNSS container, a magnetic sensor or a similar sensor. In addition, the electronic device preferably includes a communication interface, which is used to wirelessly connect the electric bicycle to an external device, such as a smartphone and / or a server.

[0011] In addition, it is proposed that at least one safety element is arranged outside the receiving space. As a result, the effectiveness of the safety element can be advantageously increased. Alternatively, it is also conceivable that the safety element is arranged in the receiving space, in particular in the region of the electrical contact element of the corresponding bicycle component.

[0012] Furthermore, it is proposed that the securing element has a guide bevel towards the receiving space. Advantageously, this can simplify the connection process in the case of a desired connection or desired release by the user.

[0013] It is further proposed that the safety element is designed to be spaced apart from the bicycle component in the locked state. This can further optimize the connection process in an advantageous ergonomic manner. The bicycle component in particular has a stop, on which the safety element stops depending on the direction and position of the force acting on the bicycle component and prevents further relative movement. The distance between the safety element and the stop is preferably at least 10% of the unlocking distance. Preferably at least 20% of the unlocking distance is required to loosen the connection between the bicycle components.

[0014] Furthermore, it is proposed that the rigid connection unit is designed in one piece. This advantageously ensures a high stability of the rigid connection unit. The rigid connection is preferably made of a synthetic material, in particular a hard plastic.

[0015] Furthermore, it is proposed that the movable locking element is rotatably mounted. This advantageously enables a compact design of the movable connecting unit.

[0016] In addition, it is proposed that the movable locking element is preloaded, in particular preloaded by means of a spring force. Thus, a reliable fixation of the releasable first bicycle component in the second bicycle component can be advantageously ensured. The movable locking element can be directly or indirectly exerted with force by a spring element. The spring element can be constructed of a metal spring or a plastic spring. The spring element can be constructed, for example, as an annular spring, a helical spring or a helical torsion spring. It is also conceivable that the spring element is constructed of an elastic plastic.

[0017] It is further proposed that the movable locking element has a connecting element receiving space which is designed in such a way that a linear movement of the connecting element in the movable, in particular rotatable locking element is possible. This advantageously makes it possible to achieve a comfortable actuation mechanism for the user. For this purpose, the connecting receiving portion preferably has a width which is designed to be at least 15%, in particular at least 25%, greater than the width of the matching connecting element of the rigid connecting unit.

[0018] Furthermore, it is proposed that the first detachable bicycle component is configured as a display device. The display device has at least one display element for displaying information. The display element can be configured as a light element, such as an LED, or can be configured as a display screen for displaying numerical symbols and / or graphic symbols.

[0019] Furthermore, it is proposed that the second bicycle component is designed as a holding device. The holding device preferably has a bicycle interface for mounting the second bicycle component on a handlebar or a frame of a bicycle.

[0020] Alternatively, the present invention relates in particular to a connection device for connecting a first bicycle component that can be detached to a second bicycle component in a force-locking and form-locking manner, the connection device having a rigid first connection unit and a movable second connection unit, wherein the rigid connection unit has at least one connection element, wherein the movable connection unit has at least one rotationally movable locking element. It is proposed that the connection element of the first connection unit has an undercut element that matches the undercut element of the locking element of the second connection unit, wherein the undercut elements act at least partially against the unlocking direction. As a result, the release characteristics can be advantageously optimized. The undercut element is preferably designed in a hook shape.

[0021] The unlocking direction is to be understood as a direction or a movement direction of the first bicycle part relative to the second bicycle part, which the first bicycle part passes or must pass in order to unlock or release the connection. The unlocking direction can have one or more moving parts, wherein the moving parts can be designed linearly or rotationally. The unlocking movement can be designed, for example, in two stages, wherein in a first stage a substantially linear movement is performed in the unlocking direction and in a second stage the locking is released by a rotational movement.

[0022] The connection device is especially configured in such a way that unlocking is performed without actuating an operating element, such as a button, by a user. Alternatively, it is also conceivable that the connection device has such an operating element and unlocks via a single-stage movement.

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

[0024] Furthermore, it is proposed that at least one undercut element of the connecting element extends inwardly or outwardly starting from a base surface which is arranged on the side facing the connecting element.

[0025] Furthermore, it is proposed that the undercut element is arranged laterally spaced apart from the edge of the connecting element or the locking element via the base surface. Advantageously, the combination of the base surface and the undercut element can ensure compatibility of different rigid connecting units with the same movable connecting unit.

[0026] Furthermore, it is proposed that the connecting element and the locking element each have at least two undercut elements. This can advantageously further improve the compatibility. The at least two undercut elements are spaced apart from each other, in particular via sections of the base surface.

[0027] Furthermore, it is proposed that the rigid connecting unit has at least one securing element which is arranged on a side of the rigid connecting unit opposite to the at least one undercut element, wherein the securing element and the undercut element extend in opposite directions. This can advantageously increase the stability of the connecting device.

[0028] Furthermore, it is proposed that at least one undercut element of the rigid connecting unit has a guide bevel, thereby making it possible to advantageously optimize the connecting process for the user.

[0029] Furthermore, it is proposed that the undercut element has an undercut region which extends in an angular range of between 10° and 40°, preferably between 20° and 30°, relative to the unlocking direction. This can advantageously further optimize the connection process.

[0030] Furthermore, it is proposed that the undercut region and the guide bevel are connected via a curved connecting region. As a result, the release process can be advantageously optimized.

[0031] It is further proposed that the undercut element is designed in such a way that, in the case of a force acting substantially perpendicularly to the unlocking direction, unlocking occurs starting from a force of at least 50 N, preferably at least 90 N. This advantageously makes it possible to at least partially prevent damage to the connecting device, in particular the rigid connecting unit or the movable connecting unit. The undercut element thus advantageously forms an overload protection.

[0032] Furthermore, it is proposed that the first detachable bicycle part is designed as a display device and / or the second bicycle part is designed as a holding device.

[0033] Furthermore, the invention relates to a holding device having a movable connecting unit as described above. Alternatively, it is also conceivable that the holding device comprises a rigid connecting unit.

[0034] Furthermore, the invention relates to a display device having a rigid connecting unit as described above. Alternatively, it is also conceivable that the display device comprises a movable connecting unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] exist Figure 1 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 an electric assisted bicycle or as an electric bicycle. The electric bicycle 12 comprises a connecting device 100, which is designed to connect a first detachable bicycle part 102 to a second detachable bicycle part 104 (see Figure 3 ).

[0050] The electric bicycle 12 has a housing in the form of a frame 20 or bicycle frame. Two wheels 22 are connected to the frame 20. In addition, the electric bicycle 12 has a drive unit 26, which includes an electric motor or an auxiliary motor. The electric motor is preferably configured as a permanent magnet excited brushless DC motor. The electric motor is configured as a mid-mounted motor, wherein a hub motor or a similar motor is also conceivable. The electric bicycle 12, in particular the drive unit 26 of the electric bicycle 12, is supplied with energy via a 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 connection device 25. Here, the connection is performed by means of a pivoting insertion movement.

[0051] The electric bicycle 12 includes a control unit (not shown in detail) which is assigned to the drive unit 26 by way of example and is 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 connection or communication with the battery pack 16 and other bicycle components of the electric bicycle 12, such as the front lighting device 40 and the display device 30. The display device 30 is designed to be connectable to the electric bicycle 12 without tools and forms a first bicycle component 102 by way of example.

[0052] The control unit of the electric bicycle 12 has a sensor unit. The sensor unit of the electric bicycle 12 exemplarily includes a plurality of 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.

[0053] A control unit and a drive unit 26 having an electric motor and a pedal crank shaft 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 crank shaft (not shown). The driving movement of the electric motor is preferably transmitted to the pedal crank shaft via a transmission mechanism (not shown), wherein the size of the assistance provided by the drive unit 26 is controlled or adjusted by means of the control unit. The control unit is configured to control the drive unit 26 in such a way that the rider of the electric bicycle 12 is assisted when pedaling. Preferably, the control unit is configured to be operable by the rider so that the rider can set the degree of assistance. Here, the setting can be performed, for example, via a display device 30 and / or an external device not shown, such as a smartphone.

[0054] The control unit and the sensor unit are assigned to an electronic device (not shown), which, by way of example, has a circuit board on which a computing unit in the form of a CPU, a memory unit and a sensor unit are arranged. The electronic device can be arranged substantially completely in the area of ​​the drive unit. However, it is also conceivable that the electronic device of the electric bicycle 12 is arranged completely or partially in the area of ​​another bicycle component. For example, it is also conceivable that the display device 30 is configured as an onboard computer and additionally includes a control unit for controlling the electric bicycle 12. In this case, however, the electric bicycle 12 can only be used in a state connected to the onboard computer.

[0055] The display device 30 can be releasably fastened to the handlebars 32 of the electric bicycle 12, for example. The display device 30 is designed to display information. In addition, the display device 30 includes at least one operating element (not shown), via which the user or the rider can control the display device 30 and / or the electric bicycle 12. The operating element is designed as a touch screen, for example. The display device 30 is connected to the control unit of the electric bicycle 12 in such a way that information can be exchanged. For example, the speed determined by the control unit, the set assistance level of the electric motor, the route information of the navigation unit and the charge state of the battery pack 16 can be displayed via the display device 30.

[0056] exist Figure 2 3 shows a side view of a first bicycle component 102 in the form of a display device 30 in a state of being connected to a second bicycle component 104 in the form of a holding device 106. In this case, the connection is made via a connecting device 100, which comprises a rigid connecting unit 108 and a movable connecting unit 110 (see Figure 3 ).

[0057] The display device 30 is designed to be detachable from the holding device 106 without tools. The connecting device 100 is preferably designed in such a way that both the connection and the release can be performed by one-handed operation. The display device 30 has, by way of example, a rigid connecting unit 108 of the connecting device 100 .

[0058] The holding device 106 is configured to be mounted on the electric bicycle 12. For this purpose, the holding device 106 has a mounting unit 112, which is configured, for example, in the form of a clamp. And can be fixed on the electric bicycle 12 by means of a screw connection 117 by means of a tool, in particular on the handlebar 32 of the electric bicycle 12. In particular, the mounting unit 112 is designed so flexibly that it can be fixed on handlebars with different diameters. In addition, the holding device 106 has a movable connecting unit 110, which is adapted to the rigid connecting unit 108 of the display device 30.

[0059] exist Figure 3 2 shows a longitudinal section through two bicycle components 102 , 104 , in particular a longitudinal section through a rigid connecting unit 108 of the display device 30 and a movable connecting unit 110 of the holding device 106 .

[0060] Here, in order to connect the two bicycle components 102 , 104 , via a first connecting movement, the first bicycle component 102 is pushed onto the second bicycle component 104 essentially linearly along a first connecting direction 112 and then via a second connecting movement, the first bicycle component 102 is pivoted to engage into the second bicycle component 104 .

[0061] The rigid connection unit 108 of the display device 30 has two connection elements 114, namely a first connection element 113 and a second connection element 115, which extend toward each other from a base 116 of the rigid connection unit 108. Here, the connection element 114 is particularly configured to be substantially rigid. Here, the first connection element 113 of the rigid connection unit 108 and the second connection element 115 of the rigid connection unit 108 are particularly arranged on different sides of the movable connection unit 110. The rigid connection unit 108 can have one or more first connection elements and / or second connection elements 113, 115, respectively.

[0062] By way of example, viewed in cross section, the base body 116 is substantially U-shaped and opens up a receiving space which is designed to receive the movable connecting unit 110. The rigid connecting unit 108 is, by way of example, constructed in one piece. The rigid connecting unit 108 is constructed on the outer side of a housing 118 of the display device 30. The housing 118 of the display device 30 has, by way of example, two housing components 120 which are constructed as housing half shells, wherein the rigid connecting unit 108 is, by way of example, constructed in one piece with one of the housing components 120. Here, the connecting elements 114 of the rigid connecting unit are so firmly connected to one another that they do not perform relative movements toward one another during the connecting or releasing process.

[0063] The movable connecting unit 110 has two connecting elements 122, namely a first connecting element 121 and a second connecting element 123, which are adapted to the connecting element 114 of the rigid connecting unit 108. The movable connecting unit 110 can have one or more first and / or second connecting elements 121, 123, respectively.

[0064] The first connecting element 121 of the movable connecting unit 110 is designed to be essentially rigid and forms a receptacle for engaging the first connecting element 113 of the rigid connecting unit.

[0065] 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 supported in the holding device 106. The second connecting element 123 of the movable connecting unit 110 is particularly supported so as to be rotatable about an axis of rotation 128. The second connecting element 123 of the movable connecting unit 110 is also connected to a restoring element 130 in such a way that the restoring element 130 exerts a force on the movable locking element 126 in the direction of the locked state. The restoring element 130 is designed, for example, as a spring element in the form of a helical spring.

[0066] In the connected state, the connecting element 122 of the movable connecting unit 110 is connected to the connecting element 114 of the rigid connecting unit 108 , for example, by means of a positive fit.

[0067] In order 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 exerting a force on the first bicycle component 102 in an unlocking direction 111 corresponding 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, as a result, the second connecting element 123 of the movable connecting unit 108 is moved toward the first connecting element 121 of the movable connecting unit 108, whereby the distance is shortened and the connecting elements 122 of the movable connecting unit 110 are moved toward each other.

[0068] During the pivoting of the second connecting element 123 of the movable connecting unit 110, the movement of the first bicycle component 102, in particular the second connecting element 115 of the rigid connecting unit 108, takes place substantially linearly. 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 connecting element 115 to be received and adapted. In contrast, the first connecting element 121 of the movable connecting unit 110 has a connecting element receiving portion 134, which is substantially matched in terms of its width to the width of the adapted first connecting element 113 of the rigid connecting unit 108, thereby achieving substantially linear guidance in this region.

[0069] The movement of the first bicycle component 102 in 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 form-fitting connection is now released by means of a pivoting movement, so that the first bicycle component 102 can be removed from the second bicycle component 104.

[0070] Here, the connection device 100 is designed in such a way that unlocking can occur even when a force acts on the bicycle component, the direction of which does not completely correspond to the unlocking direction 111. This has the advantage for the user that the connection can be released and established more easily.

[0071] However, in order to ensure that the connection does not accidentally become loose, 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 relative to the movable connecting unit 110 depending on the direction and / or position of the force acting on the first detachable bicycle part 102.

[0072] The securing element 140 is assigned to the rigid connecting unit 108 by way of example. The securing element 140 is arranged by way of example in the region of the second connecting element 115 of the rigid connecting unit 108. The securing element 140 is arranged on the base body 116 of the rigid connecting unit 108, in particular on the side facing away from the second connecting element 115 of the rigid connecting unit 108. The securing element 140 is designed by way of example as a convex exist Figure 3 In the locked state or connected state depicted in FIG, the securing element 140 is arranged spaced apart 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 form-locking connection of the first connecting elements 113, 121 that are adapted to each other.

[0073] Here, the securing element 140 is arranged and designed in such a way that, when a first force 142 acts (although the first force has a component in the unlocking direction 111, it also has a high component perpendicular to the unlocking direction 111), the securing element 140 abuts against an outer surface 144 of the second bicycle component 104, in particular against a stop element 151 of the connecting device 100 provided for this purpose, and comes to rest there, as in Figure 4. As a result, unlocking of the first bicycle component 102 is advantageously effectively prevented in the case of a first force 142. Here, the movable locking element 126 is pivoted only in an unimportant area. Here, the first force 142 is particularly directed in such a way 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 onto the first bicycle component 102, which impact acts in the direction of the handlebar 32. The greater the distance of the first force 142 acting on the housing of the first bicycle component 102 relative to the second connecting element 115, the greater the lever effect. For this reason, a different size of the first bicycle component 102 may also need to be adapted to the securing element 140 or the securing element 140 may be omitted in the case of a smaller housing.

[0074] If the force acts substantially completely on the first bicycle component 102 in the unlocking direction 111 , the securing element 140 has a guiding function in addition to the blocking function in the event of an unintended force action.

[0075] For this purpose, the securing element 140 has a guide bevel 146 which faces the receiving space of the rigid connecting unit 108. In particular, the guide bevel 146 of the securing element 140 faces the second bicycle component 104 in the connected state. The guide bevel 146 is designed to be inclined relative to the unlocking direction 111, preferably, the guide bevel 140 has an angle of between 20° and 70°, preferably between 30° and 60° relative to the unlocking direction 111.

[0076] By the force action in the unlocking direction 111, the securing element 140 rests with the guiding bevel 146 on the outer side of the second bicycle component 104. Here, by the inclined configuration of the guiding bevel 146, the guiding by the securing element 140 is achieved by a further force action in the unlocking direction 111, in that the second connecting element 115 of the rigid connecting unit 108 of the first bicycle component 102 is pressed away from the securing element 140 by a height 141, such as at Figure 5 Advantageously, the form-locking connection of the adapted first connecting elements 113 , 121 can then be released by a pivoting movement.

[0077] Also in Figure 51 shows an electric contact pin 145 which is designed to electrically connect the first bicycle component 102 to the second bicycle component 104. Via this electrical connection, the first bicycle component 102 can be supplied with energy via the second bicycle component 104 or information can be exchanged between the bicycle components 102, 104. The contact pin 145 is exemplarily spring-mounted so that the contact pin 145 is always pressed against a matching contact element (not shown) of the first bicycle component 102 by a pressing force.

[0078] exist Figure 5a 2 shows an alternative embodiment of a connecting device 100a, wherein the first and the second bicycle component 102a, 104a substantially correspond to the previously described bicycle components 102, 104, but differ with regard to the embodiment of the securing element 140a.

[0079] The securing element 140a is arranged, for example, in the region of the first connecting element 113a, 121a. The securing element 140a is in particular designed as a projection 148a, which is arranged on the first connecting element 113a of the rigid connecting unit 108a and extends into the connecting element receptacle 134a. The first connecting element 113a of the rigid connecting unit 108a has a recess 150a adapted to the securing element 140a.

[0080] exist Figure 5b 2 shows another alternative embodiment of a connecting device 100 b , wherein the first and the second bicycle component 102 b , 104 b substantially correspond to the previously described bicycle components 102 , 104 , but the embodiment of the securing element 140 b is different.

[0081] The securing element 140b is arranged in the region of the second connecting elements 123b, 115b. The securing element 140b is designed as a user-movable securing element 140b which is clamped between the first bicycle component 102b and the second bicycle component 104 by pressing after the bicycle components 102b, 104b are connected.

[0082] For this purpose, the securing element 140b can be connected to the housing of the first bicycle component 102b, for example, via a universal joint or a hinge. Alternatively, it is also conceivable that the securing element 140b is integrally formed with one of the housing components 120b and is elastically formed by its shape, for example, in the form of a thin clip, which, as schematically shown, is slightly bent for securing.

[0083] exist Figure 5c2 shows another alternative embodiment of a connecting device 100 c , wherein the first and the second bicycle component 102 c , 104 c substantially correspond to the previously described bicycle components 102 , 104 , but the embodiment of the securing element 140 c is different.

[0084] The connecting device 100c has two securing elements 140c, which are formed in the region of a contact pin 145c of the second bicycle component 104c. The contact pin 145c is withdrawn from the second bicycle component 104c in the region of an exit opening 149c, wherein the securing element 140c is formed by a collar-shaped configuration of the exit opening 149c. The contact element 153c of the first bicycle component 102c, which is matched to the contact pin 145c, is arranged inwardly offset in a receiving recess 147c, which is matched to the securing element 140c.

[0085] In this case, the securing element 140c and the receiving recess 147c are designed such that, similar to Figure 3 In the event of a force 142 in the unlocking direction 111 c , unlocking is prevented and in the event of a force in the unlocking direction 111 c , it is guided by the securing element 140 c , in particular by a guide bevel 146 c of the securing element 140 c .

[0086] In addition to the securing element 140 for preventing an unintentional release of the connection by a first force 142 from above or obliquely from above, Figure 3 The connecting device 100 has two undercut elements 160 , 162 that are matched to each other and act at least partially counter to the unlocking direction 111 . Here, the undercut elements 160 , 162 are arranged in the region of the movable locking element 126 of the movable connecting unit 110 .

[0087] The rigid connecting unit 108 has, by way of example, two first undercut elements 160 , and the movable connecting unit has, by way of example, two second undercut elements 162 .

[0088] The first undercut element 160 of the rigid connecting unit 108 is arranged on the second connecting element 115 of the rigid connecting unit 108 and Figure 6 is shown in side view and is Figure 7 The first undercut element 160 is arranged on a side which is associated with the second connecting element 123 , in particular with the movable locking element 126 .

[0089] Here, the first undercut element 160 extends outwards starting from a base surface 166, which is arranged on the side facing the movable locking element 126. Here, the two undercut elements 160 are separated from each other via a section with the base surface 166 and are spaced apart from the edge of the second connecting element 115 of the rigid connecting unit 108 via a corresponding section with the base surface 166.

[0090] The undercut element 160 has a guide bevel 168 which points forward in the unlocking direction 111. In contrast, the undercut element 160 has at least one undercut region 170 in each case opposite to the unlocking direction 111. The undercut region 170 is provided for forming an undercut and in the connected state completely or at least partially rests on an adapted undercut element 162 of the movable connecting unit 110. The undercut region 170 is formed by a substantially planar surface which extends at an angle of approximately 45° to the unlocking direction 111. In particular, the undercut region 170 has a smaller acute angle to the unlocking direction 111 than the guide bevel 168 has to the unlocking direction 111.

[0091] The undercut region 170 and the guide bevel 168 are connected to one another via a curved connecting region 172 which extends in the direction of the adapted connecting element 115 .

[0092] exist Figure 8 1 shows a movable locking element 126 in a three-dimensional view, wherein the movable locking element 126 has two adapted second undercut elements 162. Here, the two second undercut elements 162 extend inwardly from the base surface 174. The second undercut elements 162 extend in particular away from the second connecting element 115 of the rigid connecting unit 108.

[0093] By combining the undercut elements 160, 162 with the respective base surfaces 166, 174, the mechanical device can be configured such that the movable connecting unit 110 is also compatible with an alternative and not shown rigid connecting unit which does not have the additional undercut element 160. This can be advantageous, for example, in the case of a first bicycle component which is so compact that no second force 143 can be exerted on it from below, since this direction is essentially covered by the second bicycle component 104.

[0094] The undercut elements 160, 162 are provided in particular to prevent the first bicycle component 102 from being released from the second bicycle component 104 when a second force 143 acts on the first bicycle component 102. The second force 143 is directed transversely, in particular substantially perpendicularly, to the unlocking direction 111 and away from the first bicycle component 102. In this case, the second force 143 acts in particular on the first bicycle component 102 when it is impacted from below. This can occur accidentally by a user or due to a fall.

[0095] exist Fig. 9 2 shows the bicycle components 102 , 104 in the event of such an unexpected impact from below, wherein a second force 143 acts on the first bicycle component 102 .

[0096] The first bicycle component 102, in particular the second connecting element 115 of the rigid connecting unit 108, is pressed away from the second bicycle component 104 by the second force 143 and moves upward in the depicted view. By connecting 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 transmitted to the movable locking element 126, which thereby pivots against the spring force and, due to the undercut elements 160, 162, entrains the second connecting element 115 of the rigid connecting unit 108, wherein the connection is temporarily retained, as in Fig. 9 Here, the connecting device 100, in particular the undercut elements 160, 162, are designed such that, when a force is applied perpendicularly to the unlocking direction 111 by the second force 143, unlocking occurs starting 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.

[0097] Therefore, the connecting device 100 is designed such that the positive connection between the bicycle components 102, 104 is releasable in the region of the first connecting elements 113, 121 or in the region of the second connecting elements 115, 123 in dependence on the action of force. In particular, in the case of an action of force provided in the unlocking direction 111 or in the case of an unexpected first force 142, the connection is first released in the region of the first connecting elements 113, 121, and in the case of an unexpected action of a force 143, the connection is first released in the region of the second connecting elements 115, 123.
