Technical Field

[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, a holding device and a display device. Background Art

[0002] DE 20 2019 104 857 U1 describes a holding device for a display device of a two-wheeled vehicle. Summary of the invention

[0003] The invention relates in particular to a connection device for connecting a first releasable bicycle part to a second bicycle part in a force-locking and form-locking manner, the connection device having a first rigid connection unit and a second movable connection unit, wherein the rigid connection unit has at least two connection elements, which extend from a base body of the rigid connection unit toward each other and form a receiving space for receiving the second movable connection unit, wherein the movable connection unit has at least one movable locking element. The invention proposes that the rigid connection unit has at least one securing element, which is designed to block or guide a relative movement of the rigid connection unit relative to the movable connection unit, depending on the direction and / or location of the force acting on the first releasable bicycle part. Advantageously, a robust connection of the second bicycle part to 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 detachable bicycle part is to be understood in particular as a bicycle part which is designed to be detachable without tools and without damage. The first bicycle part can be, for example, a display device, a holder for a smartphone, an onboard computer, a beverage bottle, a holder for a beverage bottle, a lighting unit, a bicycle lock, a battery pack of a bicycle for supplying power to the bicycle, or the like.

[0005] Preferably, the second bicycle component is configured as a holding device for the first bicycle component. The second bicycle component can be configured to be firmly connected to the bicycle or to be connected to the bicycle in a releasable manner. In particular, the second bicycle component is configured so that it can be connected to the bicycle by means of a tool, for example, via a screw connection. It is also conceivable that the second bicycle component is configured to be integrated in a component of the bicycle, for example, in a frame of the bicycle.

[0006] Alternatively, it is also conceivable that the connecting device is designed for another component, 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 as a connecting unit which can only be moved as a whole during the connecting process and in which connecting elements assigned to the rigid connecting unit substantially do not perform any relative movement 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 undergo relative movement with respect to one another during the connecting process. For this purpose, the movable connecting unit has at least one movable locking element which is mounted linearly and / or rotationally movable. Alternatively or additionally, it is also conceivable that the relative movement is achieved by plastic or elastic deformation of the movable locking element.

[0009] The safety element can be constructed in one piece or in one piece with the rigid connection unit. In the context of the present application, one piece should be understood in particular to mean that the component is made of one part, rather than being connected to each other in a force-locking, shape-locking and / or material-locking manner. Therefore, the parts of the one-piece structure are at least partially or completely constructed of the same material. The safety element can have a reinforcing element, which is, 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 receive force. The connection device can have one or more safety elements. Preferably, the safety element is constructed so that, depending on the position and direction of the force, relative movement is only blocked until a threshold value of the force, wherein, when the force is exceeded, the connection is loosened.

[0010] Here, the bicycle component can be set for bicycles and especially for electric bicycles. In the context of the present application, an electric bicycle should be understood as a bicycle having a drive unit for supporting the driver. Preferably, the electric bicycle is configured as an eBike, an electric assisted bicycle (Pedelec), an S-Pedelec, a cargo bicycle, or a folding bicycle. The drive unit has a motor, which can be configured as a mid-level motor or a hub motor, for example. Preferably, the motor is configured as an electric motor. The drive unit is connected to a battery pack for supplying energy to the drive unit. Preferably, the housing of the battery pack is configured to be connected to an electric bicycle, especially a frame of an electric bicycle, in a releasable manner. The electric bicycle includes an electronic device having a control device for controlling or regulating the electric bicycle. Preferably, the electronic device includes a sensor unit, wherein the sensor unit can have, for example, a motion sensor, a torque sensor, a speed sensor, a GNSS receiver, a magnetic sensor or the like. In addition, preferably, the electronic device includes a communication interface for wirelessly connecting the electric bicycle to an external device and / or a server, such as a smart phone.

[0011] It is further proposed that at least one securing element is arranged outside the receiving space. Advantageously, the effectiveness of the securing element can be increased thereby. Alternatively, it is also conceivable that the securing element is arranged in the receiving space, in particular in the region of an electrical contact element of the corresponding bicycle component.

[0012] In addition, it is proposed that the safety element has an introduction bevel facing the receiving space. Advantageously, this can simplify the connection process when the user wants to connect or wants to release.

[0013] It is further proposed that the securing element is designed to be spaced apart from the bicycle component in the locked state. Advantageously, the connection process can thereby be further optimized in terms of ergonomics. The bicycle component in particular has a stop, against which the securing element abuts depending on the direction and location of the force acting on the bicycle component and blocks further relative movement. The distance between the securing element and the stop is preferably at least 10%, preferably at least 20%, of the unlocking distance required to release the connection between the bicycle components.

[0014] Furthermore, it is proposed that the rigid connecting unit is constructed in one piece. Advantageously, a high robustness of the rigid connecting unit can be ensured thereby. Preferably, the rigid connecting unit is constructed from plastic, in particular from hard plastic.

[0015] Furthermore, it is proposed that the movable locking element is rotatably mounted. Advantageously, a compact design of the movable connecting unit can be achieved thereby.

[0016] In addition, it is proposed that the movable connecting unit is pre-tensioned, in particular pre-tensioned by means of a spring force. Advantageously, a reliable fixation of the first bicycle component that can be detached in the second bicycle component can be ensured thereby. The movable locking element can be loaded with force directly or indirectly by a spring element. The spring element can be constructed of a metal spring or a plastic spring. For example, the spring element can be constructed as an annular spring, a helical spring or a helical torsion spring (Schenkelfeder). 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 receptacle which is designed such that the connecting element can be moved linearly in the movable, in particular rotatable locking element. Advantageously, a particularly comfortable actuation mechanism for the user can be achieved thereby. For this purpose, the width of the connecting receptacle is preferably at least 10%, in particular at least 25%, greater than the width of a corresponding connecting element of the rigid connecting unit.

[0018] In addition, it is proposed that the first releasable 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-emitting 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. Preferably, the holding device has a bicycle interface for mounting the second bicycle component on a handlebar or on a frame of a bicycle.

[0020] The invention relates to a connecting device for connecting a first bicycle part that can be detached 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 one connecting element, wherein the movable connecting unit has at least one rotationally movable locking element. The invention proposes that the connecting element of the first connecting unit has an undercut element that corresponds to the undercut element of the locking element of the second connecting unit, wherein the undercut elements act at least partially against the unlocking direction. Advantageously, the triggering characteristics can be optimized thereby. Preferably, the undercut element is designed in a hook shape.

[0021] The unlocking direction is understood to be a direction or a movement direction of the first bicycle part relative to the second bicycle part, through which the first bicycle part moves or needs to move in order to unlock or to release the connection. The unlocking direction can have one or more movement components, wherein the movement components 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 in the unlocking direction is performed, and in a second stage, the locking is released via a rotational movement.

[0022] The connection device is particularly configured so that unlocking is achieved by a user without operating an operating element, such as a button. Alternatively, it is also conceivable that the connection device has an operating element of this type and unlocking is achieved by a single-stage motion.

[0023] It is further proposed that at least one undercut element of the connecting element extends inwardly or outwardly starting from a bottom surface arranged on the side facing the locking element.

[0024] It is further proposed that at least one undercut element of the locking element extends outwardly or inwardly starting from a bottom surface 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 edge of the locking element via the bottom surface. Advantageously, the combination of the bottom surface and the undercut element can ensure compatibility of different rigid connecting units with the same movable connecting unit.

[0026] It is further proposed that the connecting element and the locking element each have at least two undercut elements. Advantageously, the compatibility can be further improved thereby. In particular, the at least two undercut elements are spaced apart from each other via sections of the bottom surface.

[0027] It is further proposed that the rigid connecting element has at least one securing element which is arranged on the side of the rigid connecting element opposite to the at least one undercut element, wherein the securing element and the undercut element extend in opposite directions. Advantageously, the robustness of the connecting device can be increased thereby.

[0028] Furthermore, it is proposed that at least one undercut element of the rigid connecting element has an insertion bevel. Advantageously, the connecting process can thereby be optimized for the user.

[0029] It is further 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. Advantageously, the connection process can thereby be further optimized.

[0030] It is further proposed that the undercut region and the insertion bevel are connected via a curved connecting region. Advantageously, the release process can be optimized thereby.

[0031] It is further proposed that the undercut element is designed in such a way that, under the action of a force substantially perpendicular to the unlocking direction, unlocking is achieved starting from a force of at least 50 N, preferably at least 90 N. Advantageously, damage to the connecting device, in particular a rigid connecting unit or a movable connecting unit, can thereby be at least partially prevented. Advantageously, the undercut element thus forms an overload protection.

[0032] 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.

[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 has a rigid connecting unit.

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

[0049] exist Figure 11 shows a side view of a bicycle 10, in particular an electric bicycle 12, which has 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 an E-Bike. 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. Preferably, the electric motor is designed as a permanent magnet excited brushless DC motor. By way of example, the electric motor is designed as a mid-range motor, wherein hub motors or the like are also conceivable. Energy is supplied to the drive unit 26 of the electric bicycle 12, in particular the electric bicycle 12, 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. Here, by way of example, the connection is realized by means of a pivoting movement.

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

[0052] The control unit of the electric bicycle 12 has a sensor unit. Exemplarily, the sensor unit of the electric bicycle 12 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] The control unit and the drive unit 26 with the electric motor and the pedal crank shaft are arranged in a drive housing 27, which is 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). Preferably, the drive movement of the electric motor is transmitted to the pedal crank shaft via a transmission (not shown), wherein the magnitude of the support provided by the drive unit 26 is controlled or adjusted by means of the control unit. The control unit is designed to control the drive unit 26 in such a way that the driver of the electric bicycle 12 is supported when pedaling. Preferably, the control unit is designed to be operable by the driver so that the driver can adjust the degree of support. This adjustment can be made, for example, via the 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, for 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 ​​other bicycle components. 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. However, in this case, the electric bicycle 12 can only be used in a state connected to the onboard computer.

[0055] The display device 30 is fastened, for example, in a releasable manner to a handlebar 32 of the electric bicycle 12. 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 a user or driver can control the display device 30 and / or the electric bicycle 12. The operating element is designed, for example, as a touch-sensitive display. 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 support 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. The connection is realized 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. Preferably, the connecting device 100 is designed so that both the connection and the detachment can be achieved by one-handed operation. By way of example, the display device 30 has 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 an assembly unit 112, which is configured, for example, in the form 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 with the aid of a tool. The assembly unit 112 is particularly flexibly configured so that it can be fixed on different handlebars with different diameters. In addition, the holding device 106 has a movable connecting unit 110, which corresponds to the rigid connecting unit 108 of the display device 30.

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

[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 subsequently, via a second connecting movement, a pivoting movement of the first bicycle component 102 is achieved for engagement 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 in particular 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 in particular arranged on different sides of the movable connection unit 110. The rigid connection unit 108 can have one or more first and / or second connection elements 113, 115, respectively.

[0062] By way of example, when viewed in cross section, the base body 116 is substantially U-shaped and opens a receiving space which is configured to receive a movable connecting unit 110. By way of example, the rigid connecting unit 108 is configured in one piece. The rigid connecting unit 108 is configured on the outer side of a housing 118 of the display device 30. By way of example, the housing 118 of the display device 30 comprises two housing parts 120 which are configured as housing half shells, wherein the rigid connecting unit 108 is configured in one piece with one of the housing parts 120, by way of example. Here, the connecting elements 114 of the rigid connecting unit are so firmly connected to one another that they do not perform relative movements relative to one another during a connecting process or a disconnecting 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 correspond to the connecting elements 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 configured as a movable locking element 126. The second connecting element 123 is supported on the holding device 106 in a movable manner. In particular, the second connecting element 123 of the movable connecting unit 110 is supported in a manner that allows rotation about the rotation axis 128. In addition, the second connecting element 123 of the movable connecting unit 110 is connected to the reset element 130 in such a way that the reset element 130 applies a force to the movable locking element 126 in the direction of the locked state. The reset element 130 is configured as a spring element in the form of a helical spring, for example.

[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, via a form 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 a force acting on the first bicycle component 102 in the direction of an 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, 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 spacing 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 second connecting element 115 of the first bicycle component 102, in particular 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 corresponding connecting element 115 to be received. In contrast, the first connecting element 121 of the movable connecting unit 110 has a connecting element receiving portion 134, which is matched in its width to the width of the corresponding first connecting element 113 of the rigid connecting unit 108, thereby achieving a substantially linear guidance in this area.

[0069] The movement of the first bicycle component 102 in the unlocking direction 111 is continued 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-locking 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] The connection device 100 is designed in such a way that unlocking is possible even when the direction of the force acting on the bicycle component 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 and / or guide a relative movement of the rigid connecting unit 108 relative to the movable connecting unit 110, depending on the direction and / or location of the force acting on the first detachable bicycle part 102.

[0072] By way of example, the securing element 140 is associated with the rigid connecting unit 108. By way of 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 the base body 116 of the rigid connecting unit 108 on the side facing away from the second connecting element 115 of the rigid connecting unit 108. By way of example, the securing element 140 is designed in the form of a lug. Figure 3 In the locked or connected state shown, the securing element 140 is arranged spaced apart from the second bicycle component 104, in particular from the movable connecting unit 110. The spacing is preferably at least 10%, preferably at least 25%, of the travel in the unlocking direction 111 for releasing the form-locking connection of the first connecting elements 113, 121 corresponding to each other.

[0073] Here, the securing element 140 is arranged and constructed 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 stops and abuts against an outer surface 144 of the second bicycle component 104, in particular, stops and abuts against a stop element 151 of the connecting device 100 provided for this purpose, as shown in FIG. Figure 4 As shown. Advantageously, therefore, unlocking of the first bicycle component 102 is 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 directed in particular 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 on the first bicycle component 102 from above, which impact acts in the direction of the handlebar 32. The further the first force 142 acting on the housing of the first bicycle component 102 is from the second connecting element 115, the greater the lever effect. For this reason, other parameters of the first bicycle component 102 may also need to be adapted to the securing element 140, or the securing element 140 can be omitted in the case of a smaller housing.

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

[0075] For this purpose, the securing element 140 has an insertion bevel 146, which 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 configured obliquely with respect to the unlocking direction 111, preferably, the insertion bevel 146 has an angle of between 20° and 70°, preferably between 30° and 60° with respect to the unlocking direction 111.

[0076] By the force action in the unlocking direction 111, the securing element 140 comes to bear against the outer side of the second bicycle component 104 by means of the introduction ramp 146. Here, by the inclined configuration of the introduction ramp 146, the securing element 140 is guided by the further force action in the unlocking direction 111 in such a way 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 the height 141 of the securing element 104, as shown in FIG. Figure 4 Advantageously, the form-locking of the corresponding first connecting elements 113 , 121 can then be released by a pivoting movement.

[0077] Also in Figure 5 1 shows an electrical contact pin 145 which is configured to electrically connect the first bicycle component 102 to the second bicycle component 104. Via the electrical connection, power can be supplied to the first bicycle component 102 via the second bicycle component 104 or information can be exchanged between the bicycle components 102, 104. By way of example, the contact pin 145 is resiliently mounted so that the contact pin 145 is always pressed against a corresponding 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 , in which the first and second bicycle components 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. In particular, the securing element 140a is configured as a lug 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 corresponding to the securing element 140a.

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

[0081] Here, the securing element 140b is arranged in the region of the second connecting elements 123b, 115b. For example, 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 compression 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 part 102b, for example, via a hinge or a chain. Alternatively, it is also conceivable that the securing element 140b is integrally formed with one of the housing parts 120b and is elastically formed due to its shape, for example, as a thin clip as shown in the figure, which is easy to bend for security.

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

[0084] By way of example, the connecting device 100c has two securing elements 140c, which are formed in the region of 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, wherein the securing elements 140c are formed by the collar-shaped design of the outlet opening 149c. The contact elements 153c of the first bicycle component 102c corresponding to the contact pins 145c are arranged inwardly offset in receiving recesses 147c, which correspond to the securing elements 140c.

[0085] The securing element 140c and the receiving recess 147c are designed in such a way that when Figure 3 In the case of a force similar to the force 142 in the unlocking direction 111 c , the unlocking is blocked and in the case of a force in the unlocking direction 111 c , it is guided by the securing element 140 c , in particular by the introduction 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 due to a first force 142 from above or from obliquely above, Figure 3 The connecting device 100 also 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.

[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 in Figure 7 The first undercut element 160 is arranged on the 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 bottom 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 by a section with a bottom surface 166 and are each spaced apart from the edge of the second connecting element 115 of the rigid connecting unit 108 by a section with a bottom surface 166.

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

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

[0092] exist Figure 8 1 shows a movable locking element 126 in a perspective view, wherein the movable locking element 126 has two corresponding second undercut elements 162. Here, the two second undercut elements 162 extend inwardly from the bottom surface 174. In particular, the second undercut elements 162 extend away from the second connecting element 115 of the rigid connecting unit 108.

[0093] By combining the undercut elements 160, 162 with the corresponding bottom surfaces 166, 174, the mechanical device can be designed in such a way that the movable connecting unit 110 is also compatible with an alternative, not shown, rigid connecting unit that does not have the additional undercut element 160. This can be advantageous, for example, in the case of first bicycle components that are so compact that the second force 143 cannot be exerted on them from below because 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 perpendicularly, to the unlocking direction 111 and away from the first bicycle component 102. The second force 143 acts in particular on the first bicycle component 102 when an impact occurs from below. This can occur accidentally by a user or due to a fall.

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

[0096] By means of the second force 143, the first bicycle component 102, in particular the second connecting element 115 of the rigid connecting unit 108, is pushed apart relative to the second bicycle component 104 and moves upward in the depicted view. By means of the connection of the second connecting element 115 of the rigid connecting unit 108 with the movable locking element 126 of the movable connecting unit 110, the second force 1434 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 shown in FIG. Fig. 9 The connecting device 100, in particular the undercut elements 160, 162, is designed in this way so that when a force is applied perpendicularly to the unlocking direction 111 by the second force 143, unlocking is achieved starting from a second force 143 of at least 50N, preferably at least 90N, 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 can be released in response to the action of a force in the region of the first connecting elements 113, 121 or in the region of the second connecting elements 115, 123. In particular, in the case of an action of a force in the intended unlocking direction 111 or in the case of an unexpected action of a 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.
