Description

[0001] The invention relates to a connecting device for detachably connecting two assemblies according to the preamble of claim 1.

[0002] Such a connecting device has a locking module that is assigned to a first of the assemblies and can be detachably connected to a second of the assemblies to create a connection between the assemblies.

[0003] Such a connecting device can be used, for example, on a vehicle, such as a bicycle, to attach a component, such as an electronic device like a mobile phone or a navigation system. The locking module establishes a connection to the component being attached, such as the electronic device. The locking module must be positioned on the vehicle so that a (removable) connection can be made via the locking module.

[0004] From WO 2019 / 086648 A2, a connection device is known in which a closure module has a vacuum element that can be attached to an associated attachment component in order to interact with the attachment component in a connected position by means of vacuum. An adjusting element can be adjusted to release a flow opening in order to detach the closure module from the attachment component.

[0005] A connecting device known from EP 0 689 966 B1 has a magnetic contact plate on which a suction cup is arranged. A ski carrier can be attached to the roof of a vehicle by means of this connecting device.

[0006] Documents DE 10 2015 115 561 A1, WO 2017 / 029 152 A1, DE 20 2016 104 025 U1 and DE 20 2015 103 406 U1 describe further connecting devices for the detachable joining of two assemblies.

[0007] A desirable feature of a connecting device is that the locking module can be easily attached to an associated first assembly to create a connection between this first assembly and a second assembly. For example, the locking module should be securely and reliably attached to a vehicle, such as a bicycle, to allow another assembly, such as an electronic device, to be conveniently and safely connected to the vehicle via the connecting device.

[0008] The object of the present invention is to provide a connecting device that is easy to use, in particular easy to arrange on an associated assembly, in order to create a detachable connection between assemblies.

[0009] This problem is solved by an object having the features of claim 1.

[0010] Accordingly, the connecting device comprises a coupling part connectable to the first of the assemblies, which is designed by means of an Ahead cap for mounting on a bicycle, and a connecting element for connecting the coupling part to the locking module. The connecting element has at least one engagement section designed to engage the coupling part with the locking module in a positive-locking and / or force-locking manner in an engagement direction transverse to the application direction, interacting with at least one of the locking module and the coupling part.

[0011] The locking module serves to create a detachable connection between two assemblies. For this purpose, the locking module is permanently attached to a corresponding first assembly and is intended to create a detachable connection with a second assembly, thus establishing a connection between the assemblies via the locking module.

[0012] The locking module can establish a connection with the second assembly according to very different operating principles, for example a connection by means of mechanical locking, by means of magnetic attraction, by means of negative pressure or a combination of such different operating principles.

[0013] While the locking module is designed to establish a (removable) connection with the second assembly, it can also be connected to the first assembly via the coupling element, thus fixing it in a coupled position on the first assembly. The coupling element therefore connects the locking module to the first assembly, allowing the second assembly to be connected to the first assembly via the locking module attached to the first assembly.

[0014] To create a simple, robust connection between the coupling element and the locking module, which can also be detachable if necessary (for example, to replace the locking module with a different one), a connecting element is provided. This element has one or more engagement sections that interact with the locking module and / or the coupling element in a positive-locking and / or force-locking manner, thereby establishing a connection between the locking module and the coupling element. The positive-locking engagement or force-locking connection occurs transversely to the application direction, i.e., in a plane extending perpendicular to the application direction. The positive-locking and / or force-locking connection created by the connecting element holds the locking module and the coupling element together, for example, by means of bearing surfaces.

[0015] In one embodiment, the connecting element, for example, encompasses the locking module and / or the coupling part around the insertion direction. This means that the connecting element engages at an angle greater than 180° around the insertion direction and is in contact with the locking module and / or the coupling part. The connecting element can be U- or C-shaped, but can also be (at least almost) completely closed.

[0016] In one embodiment, at least one of the locking module and the coupling part has a coupling section. The connecting element is designed to interact with the coupling section to connect the coupling part to the locking module in a form-fitting and / or force-fitting manner.

[0017] In one embodiment, the locking module has a first coupling section, while the coupling part has a second coupling section. The coupling sections are placed against each other and – once the connection between the locking module and the coupling part has been established via the connecting element – ​​are positively and / or force-fit connected to each other by means of the connecting element, by the connecting element interacting positively and / or force-fit with the coupling sections, for example, by the connecting element engaging the coupling sections.

[0018] However, it is also conceivable that only one of the locking module and coupling part has a coupling section, and the connecting element interacts exclusively with the coupling section of that one locking module and coupling part by engaging with the coupling section in a positive-locking and / or force-locking manner via one or more engagement sections. In this case, a positive-locking and / or force-locking connection exists between the connecting element and the coupling section on that one locking module and coupling part, with the connecting element being, for example, permanently (and irrevocably) connected to the other locking module and coupling part.

[0019] In one embodiment, the coupling section has a clamping surface for interacting with the connecting element. The connecting element interacts with the coupling section via this clamping surface in a form-fit and / or force-fit manner, thus establishing a connection with the connecting element.

[0020] In one embodiment, the clamping surface is inclined obliquely to the application direction. If the clamping surface extends circumferentially around the application direction, it can, for example, have a conical basic shape, whereby the clamping surface can also be polygonal in cross-section transverse to the application direction, for example square or hexagonal, and is therefore not necessarily rotationally symmetrical.

[0021] The clamping surface can be inclined such that the connecting element, via at least one engagement section, exerts a force on the clamping surface that presses the locking module and the coupling part against each other, thus imparting a mutually directed load. A force redirection therefore occurs at the clamping surface, whereby the connecting element can, for example, introduce a radial force radial to the insertion direction, which is then redirected at the clamping surface into an axial force pressing the locking module and the coupling part together. With such a clamping surface design, the locking module and the coupling part can thus be fixed together securely and with load-bearing capacity in a play-free manner.

[0022] In addition to or as an alternative to the clamping surface, at least one engagement section of the connecting element can also be inclined obliquely to the insertion direction, whereby the inclination can be such that a force redirection occurs at the engagement section in the direction of pressing the locking module and the coupling part together.

[0023] The clamping surface, for example, extends circumferentially around the insertion direction and has a truncated cone shape. However, this is not mandatory. One or more clamping surfaces can also be shaped only in sections to interact with the connecting element at the coupling point.

[0024] If both the locking module and the coupling part each have a coupling section, then preferably both coupling sections each have a clamping surface, for example each with an inclination towards the insertion direction.

[0025] The clamping surface can be rotationally symmetrical, although this is not mandatory. The clamping surface can also deviate from a rotationally symmetrical shape.

[0026] The connecting element establishes a connection between the locking module and the coupling part by interacting with the locking module and / or the coupling part via at least one engagement section in a form-fit and / or force-fit manner, for example, by the connecting element gripping the locking module and / or the coupling part. The connecting element can, for example, be designed as a fully open bracket element that is attached to the locking module and / or the coupling part. The bracket element can have a C-shape or a U-shape. The bracket element can be designed to be elastic, at least in part, to create a clamping effect on the locking module and / or the coupling part. However, the bracket element can also be essentially rigid, particularly to create a form-fit without a clamping effect.

[0027] Such a bracket element can, for example, be implemented by a wire bracket which extends around the direction of attachment with a strut made of wire and is designed to cooperate with the locking module and / or the coupling part to establish the connection.

[0028] Instead of a wire hanger, the hanger element can also be made, for example, as a stamped and bent part, for example from sheet metal.

[0029] For example, such a clamping element can be attached to the locking module and the coupling part transversely to the direction of attachment in such a way that the clamping element is tensioned in a radial direction and, through such a tensioning effect, the locking module and the coupling part are clamped against each other in order to establish a connection between the locking module and the coupling part.

[0030] In another embodiment, the connecting element can also be formed by a ring element which, in a connected position, surrounds the locking module and / or the coupling part in a ring shape.

[0031] Such a ring element can be integral and formed in one piece. However, such a ring element can also be composed of individual segments that are, for example, connected to each other by hinges.

[0032] Such a ring element can have a circular shape in cross-section perpendicular to the direction of application, but it can also be shaped differently from such a circular shape.

[0033] The ring element can be completely closed or open at a circumferential point.

[0034] In general, the connecting element can be clamped to the locking module and / or the coupling part by, for example, the connecting element being held against the locking module and / or the coupling part under self-elastic preload, or by applying a clamping force to the connecting element via an additional clamping device.

[0035] It is also conceivable that the connecting element is not clamped to the locking module and / or the coupling part and merely grips around the locking module and / or the coupling part without exerting a clamping force on the locking module and / or the coupling part. In this case, the connecting element can, for example, act as a positive locking mechanism to axially secure the connection between the locking module and the coupling part.

[0036] If the connecting element for joining the locking module to the coupling part is to be clamped, the connecting element can, for example, have a body that extends circumferentially around the locking module and / or the coupling part, forming at least one engagement section, and a clamping device acting at the ends of the body for clamping the body. The clamping device can be clamped, for example, by a clamping element in the form of a screw to be screwed into the ends of the body or by a clamping lever in the form of an eccentric lever, so that a clamping force can be introduced into the body and thereby into the locking module and / or into the coupling part via the clamping device.

[0037] In one embodiment, the connecting element can also be formed, for example, by a longitudinally extended element, pointing, for instance, transversely to the insertion direction, which can engage with the locking module and / or the coupling part in such a way that a positive fit is created between the locking module and the coupling part. For example, the connecting element can be designed in the form of a cotter pin.

[0038] In one embodiment, the locking module has a first bearing surface and the coupling element has a second bearing surface that can be attached to the first bearing surface along an insertion direction. The locking module and the coupling element can be attached to one another using these bearing surfaces, and it is also conceivable that an intermediate element, for example in the form of an elastic element or a section of the connecting element, is arranged between the bearing surfaces.

[0039] In one embodiment, the first and second bearing surfaces are rotatable relative to each other about the direction of attachment when positioned adjacent to one another. When the locking module is connected to the coupling part via the connecting element, the locking module can thus be rotated relative to the coupling part, allowing its rotational position to be adjusted. The connecting element therefore fixes the locking module axially along the direction of attachment to the coupling part, while simultaneously allowing the bearing surfaces to rotate relative to each other and thus the locking module to rotate relative to the coupling part.

[0040] The contact surfaces can be freely and continuously rotatable relative to each other. Alternatively, the contact surfaces can have, for example, detents, allowing them to be rotated between discrete positions defined by the detents.

[0041] In another embodiment, the contact surfaces can be fixed relative to each other in a connected position. For this purpose, at least one positive locking element can be arranged on the first contact surface and at least one second positive locking element on the second contact surface. These elements engage positively with each other in a connected position, thus preventing rotation between the first and second contact surfaces. The positive locking elements can be formed, for example, by pins on one side and by engagement openings for the pins on the other, so that the positive locking elements engage with each other when the locking module and the coupling part are connected. Alternatively, the positive locking elements can also be shaped, for example, like teeth or similar features.

[0042] The positive locking elements can, for example, specify exactly one rotational position in which the locking module and the coupling part can be attached to each other. Alternatively, the positive locking elements can specify a plurality of discrete rotational positions, allowing the locking module and the coupling part to be attached and connected in different rotational positions relative to each other, with their orientations reversed.

[0043] In one embodiment, at least one first centering device is arranged on the first bearing surface and at least one second centering device on the second bearing surface. In a oriented position, the centering devices engage with each other in a form-fitting manner such that the first and second bearing surfaces are centered relative to the application direction, particularly in a plane radial to the application direction, via the centering devices. Thus, the bearing surfaces can be positioned relative to each other in a defined, centered manner using such centering devices. The centering devices can, for example, allow the bearing surfaces to rotate relative to each other about the application direction or, alternatively, fix the bearing surfaces in a rotationally fixed position relative to each other.

[0044] The centering devices can be formed, for example, by a rib extending around the insertion direction and by an annular engagement groove. Alternatively, the centering devices can be formed by a pin and an associated engagement opening.

[0045] In one embodiment, the first and / or the second bearing surface are designed to be elastically resilient along the application direction. This can be achieved, for example, by molding the first and / or the second bearing surface from an elastic material or by mounting them elastically (axially along the application direction). Because the first and / or the second bearing surface are axially resilient, tolerances can be compensated for, and the locking module and the coupling element can be fixed to each other without axial play.

[0046] In one embodiment, the locking module has a first magnetic element and the coupling part has a second magnetic element. When the locking module and the coupling part are brought into contact, the first and second magnetic elements attract each other magnetically, causing them to be drawn together.

[0047] The magnetic elements can have a centering effect by attracting the locking module and the coupling part to each other in such a way that the locking module and the coupling part are brought into a position relative to each other as intended.

[0048] The magnetic elements can, for example, each be formed by one or more permanent magnets, with the magnetic elements of the locking module and the coupling part facing each other with opposite poles and thus interacting magnetically. In another embodiment, however, one of the magnetic elements can be formed by one or more permanent magnets, while the other magnetic element is formed, for example, by a ferromagnetic armature.

[0049] An Ahead cap for mounting on a bicycle's front fork is described, for example, in US 5,095,770 and US 8,662,517. Such an Ahead cap is a cap that is attached to the upper end of a bicycle's front fork and secures a front section for connecting a handlebar to the fork.

[0050] In the connecting device, a connection between the assemblies to be fastened is established by attaching the locking module assigned to one of the assemblies to the other, second assembly. The second assembly can include a further, second locking module that can be joined to the first locking module, for example, to create a snap-fit, magnetic, and / or vacuum-operated connection between the locking modules. To establish a first connection, the locking modules can, for example, snap together. To establish a magnetic connection, the locking modules can each have one or more magnetic elements that attract each other magnetically.To create a vacuum connection, a vacuum can be applied between interconnected locking modules, holding them together. The connection is detachable, allowing the locking modules to be separated to disassemble the components.

[0051] For example, in one embodiment, the locking module can have a vacuum element that can be attached to the second assembly to create a connection between the assemblies. The vacuum element is designed to provide a holding force between the assemblies by means of a vacuum effect when the assemblies are connected. When attached, a sealed space is created between the vacuum element and the second assembly, for example, an attachment assembly of the second assembly formed by a surface section, so that the assemblies are held together by a vacuum effect. Such a connection can be particularly resistant to impact, so that impact forces can be absorbed and dissipated via the connecting device.

[0052] Such a vacuum element can, for example, be formed by a cup element that is at least partially elastic and is elastically deformed when the closure module is attached to the second assembly.

[0053] In the connected position of the connecting device, the vacuum element and the second assembly can, for example, lie flat against each other, so that there is effectively no space between the vacuum element and the second assembly. However, when the assemblies are loaded relative to each other, a force can act on the locking module relative to the second assembly. This force acts in the direction of increasing or creating a space between the vacuum element and the second assembly, resulting in a vacuum between the vacuum element and the second assembly. This creates holding forces that hold the vacuum element to the second assembly and tend to increase the more the locking module is loaded relative to the second assembly. Thus, the locking module is held to the second assembly by the vacuum effect when it is attached to the second assembly.

[0054] In one embodiment, the locking module comprises a housing and a flow opening formed in the housing for allowing airflow into a space between the second assembly and the vacuum element. In a connected position, where the locking module is attached to the second assembly, the flow opening is closed, creating a vacuum between the vacuum element and the second assembly and thus ensuring a secure connection between the two assemblies. Opening the flow opening allows air to flow between the vacuum element and the second assembly, thereby releasing the vacuum and enabling the locking module to be more easily and conveniently detached from the second assembly.

[0055] The flow opening can, for example, be formed in the base of the housing, which is surrounded by the vacuum element, shaped, for example, as an elastic cup element, in that the vacuum element extends circumferentially around the base and thus completely encloses it. In the connected position, where the closure module is attached to the second assembly, the base faces the second assembly, in particular an attachment assembly of the second assembly realized by a surface section, to which the vacuum element is attached.

[0056] In one embodiment, the closure module has an adjustable element mounted on the housing, which can be adjusted to open the flow orifice. The adjustable element can, for example, be shaped like a lever and be mounted on the housing in a tilting manner. A closure element can be arranged on the adjustable element, which can be moved together with the adjustable element. In a first position of the adjustable element, the closure element closes the flow orifice. By adjusting the adjustable element, the closure element can be moved towards the flow orifice in such a way that the flow orifice is opened, thus creating a flow path into a space between the vacuum element and the second assembly.

[0057] The adjustment element can preferably be operated manually by a user, by manipulating it. This can be done, for example, with the fingertips, by pushing or pulling on the adjustment element to move it.

[0058] In one embodiment, the locking module has a magnetic arrangement for interaction with the second assembly. The magnetic arrangement of the locking module interacts with a magnetic arrangement of the second assembly in such a way that the locking module is magnetically assisted in attaching itself to the second assembly, and the connection between the locking module and the second assembly can thus be established by magnetic attraction between them.

[0059] The magnetic arrangement of the locking module can, for example, serve to provide a magnetic attraction when the locking module and the second assembly are brought together, so that – if the locking module incorporates a vacuum element – ​​a vacuum is created in a magnetically assisted manner (preferably automatically). Upon assembly, the locking module and the second assembly are magnetically attracted to each other due to the magnetic interaction, creating a (near) vacuum between the vacuum element and the second assembly, for example, by pressing the vacuum element, which may be designed as an elastic cup element, against the second assembly.

[0060] The magnetic arrangement of the locking module can, for example, consist of a single permanent magnet or an arrangement of several permanent magnets. Similarly, the second assembly can have a magnetic arrangement in the form of a single permanent magnet or an arrangement of several permanent magnets. It is also conceivable that one magnetic arrangement (of the locking module or the second assembly) consists of a single permanent magnet or an arrangement of several permanent magnets, while the other magnetic arrangement consists of a magnetic armature made of a ferromagnetic material.

[0061] The connecting device is designed, for example, to attach an electronic device to an associated assembly. For instance, the connecting device can be used to attach a camera to a helmet, such as a ski helmet or a bicycle helmet. In another embodiment, the connecting device can also be used to attach a mobile phone, a navigation device, or another electronic communication or information device in or to a vehicle.

[0062] According to another aspect, an electronic device may have a connection device for attaching the electronic device to an assembly. The electronic device is associated with a coupling assembly. The connection device comprises: a coupling part connectable to the coupling assembly, which is designed by means of an Ahead cap for mounting on a bicycle, and a connecting element having at least one engagement section configured to connect the coupling part to the coupling assembly in a direction of engagement transverse to the mounting direction, in a form-fit and / or force-fit manner with at least one of the coupling assembly and the coupling part.

[0063] The coupling assembly can be fixed to the electronic device, for example by being formed on a housing, for example in the form of a cover such as a mobile phone case.

[0064] The connecting device can be designed in particular according to the type described above.

[0065] According to yet another aspect, a bicycle accessory assembly can include a connecting device for attaching a component, in particular an accessory part, to a bicycle. A coupling assembly is associated with the component. The connecting device comprises: a coupling part that can be connected to the coupling assembly and arranged on the bicycle, which is designed for arrangement on the bicycle by means of an Ahead cap, and a connecting element that has at least one engagement section designed to connect the coupling part to the coupling assembly in a direction of engagement transverse to the direction of attachment, in a form-fitting and / or force-fitting manner with at least one of the coupling assembly and the coupling part.

[0066] The coupling assembly can be fixed to the assembly, particularly in the form of an accessory, for example by being formed on a housing of the assembly.

[0067] The connecting device can be designed in particular according to the type described above.

[0069] Fig. 1 and Fig. 2A, Fig. Figure 2B shows views of an embodiment of a connecting device 1, which has a locking module 2 for connecting to an assembly 6, for example an electronic device such as a mobile phone or a navigation device. A detachable connection can be made to the assembly 6 via the locking module 2, wherein in a connected position the assembly 6 is held firmly and securely to the locking module 2, but the connection can be easily and conveniently released to detach the assembly 6 from the locking module 2.

[0070] The connecting device 1 serves to attach the assembly 6 to an assembly 5, for example in the form of a vehicle, such as a bicycle. In a connected position, the assembly 6 should be held firmly and reliably to the assembly 5. However, the assembly 6 should be able to be removed from the assembly 5 by releasing the connection between the assembly 6 and the locking module 2.

[0071] In the illustrated embodiment, the closure module 2 has a vacuum element 22, which is designed as an elastic cup element and is arranged on a housing 20. In the illustrated embodiment, the vacuum element 22 has a substantially rotationally symmetrical shape and encloses a base 200 of the housing 20 by forming a flow opening 201 to provide a flow path into a space between the vacuum element 22 and the assembly 6.

[0072] As can be seen from the sectional view according to Fig. As can be seen in Figure 2B, the flow opening 201 is closed by a closure element 211 in a connected position in which the closure module 2 is connected to the assembly 6. The closure element 211 is arranged on an adjusting part 21, which is tiltably mounted on the housing 20 at a bearing end 210 and projects outwards from the housing 20 in such a way that the adjusting part 21 can be manually operated by a user. The closure element 211 can thus be moved relative to the housing 20 and therefore relative to the flow opening 201 in order to open the flow opening 201 and allow an airflow into a space between the negative pressure element 22 and the assembly 6.

[0073] To connect the closure module 2 to the assembly 6, the closure module 2 and the assembly 6 can be joined together so that the vacuum element 22 comes into contact with a surface section of the assembly 6 and is thereby elastically deformed. In a connected position, the flow opening 201 is closed by the closure element 211, whereby the adjusting part 21 can, for example, be elastically pre-tensioned in the direction of this closed position, and thus the vacuum element 22 interacts with the assembly 6 under vacuum.

[0074] The locking module 2 has a magnetic arrangement 24, for example in the form of a plurality of magnetic elements formed by permanent magnets, which magnetically interacts with the assembly 6, for example a magnetic arrangement of the assembly 6. For example, the assembly 6 can have a further magnetic arrangement in the form of permanent magnets that magnetically attract the magnetic arrangement 24 of the locking module 2 or in the form of a magnetic armature, so that a magnetic attraction exists between the locking module 2 and the assembly 6 and the joining of the locking module 2 and the assembly 6 is thus magnetically supported.

[0075] It should be noted here that the locking module 2 can also be designed according to a different operating principle for connection with the assembly 6. For example, the locking module 2 can be designed to create a snap-fit ​​connection, a magnetic connection and / or a vacuum connection with the assembly 6.

[0076] The locking module 2 is to be connected to a coupling part 3 in the form of a cap, which is assigned to the assembly 5, via a connecting element 4. For this purpose, the locking module 2 has a coupling section 23, which forms a bearing surface 231 that can be brought into contact with a bearing surface 301 of the coupling part 3. The connecting element 4 can be engaged with the coupling section 23 and a coupling section 30 of the coupling part 3 in such a way that a positive-locking and / or force-locking connection is established between the connecting element 4 and the coupling section 23 of the locking module 2 on the one hand, and the coupling section 30 of the coupling part 3 on the other.

[0077] In the illustrated embodiment, the connecting element 4 has a ring-shaped form, with a body 40 that extends around an attachment direction A, along which the locking module 2 and the coupling part 3 can be attached to each other, and can be clamped via a clamping device 41.

[0078] On the inside of the body 40, engagement sections 400, 401 are formed, extending circumferentially around the insertion direction A, which can be brought into engagement with the coupling section 23 of the locking module 2 and the coupling section 30 of the coupling part 3 transversely to the insertion direction A, namely in a radially inwardly directed engagement direction E, for clamping the locking module 2 and the coupling part 3 together, as can be seen from the sectional view according to Fig. 2B is evident.

[0079] The coupling section 23 of the closure module 2 on the one hand and the coupling section 30 of the coupling part 3 on the other hand each form a clamping surface 230, 300 extending circumferentially around the application direction A, which forms a truncated cone shape and is inclined to the application direction A in such a way that the coupling section 23 and the coupling section 30 taper from the respective associated bearing surface 231, 301 in a direction away from the respective other component.

[0080] With these clamping surfaces 230, 300, the connecting element 4 can be engaged via the engagement sections 400, 401 formed on the inside of the body 40, which are shaped complementary to the frustoconical clamping surfaces 230, 300, so that the locking module 2 and the coupling part 3 are clamped together and held axially along the insertion direction A.

[0081] The contact surfaces 231, 301 can be axially resilient, allowing them to be elastically adjusted along the application direction A. For this purpose, the contact surfaces 231, 301 can be made of an elastic material. Alternatively, the contact surfaces 231, 301 can each be formed, for example, by a surface element and axially supported against the coupling element 23 of the locking module 2 or the coupling section 30 of the coupling part 3 by an elastic element, such as a spring element.

[0082] A positive-locking connection between the locking module 2 and the coupling part 3 is established via the connecting element 4, in that the connecting element 4 with the engagement sections 400, 401 engages the clamping surfaces 230, 300 and thereby holds the locking module 2 and the coupling part 3 together.

[0083] Due to the truncated conical shape of the clamping surfaces 230, 300 and the complementary shape of the engagement sections 400, 401, an axial clamping effect occurs between the locking module 2 and the coupling part 3 such that the bearing surfaces 231, 301 are axially loaded towards each other along the insertion direction A and thus pressed against each other. This results in a backlash-free fit and a firm, load-bearing hold between the locking module 2 and the coupling part 3.

[0084] In the illustrated embodiment, the body 40 of the connecting element 4 can be clamped via the clamping device 41 by reducing the radial width of the body 40 and thereby bringing it into contact with the clamping surfaces 230, 300 of the coupling section 23 and the coupling section 30.

[0085] The coupling part 3 can, for example, implement a so-called Ahead cap of a vehicle in the form of a bicycle, as shown schematically in Fig. Figure 19 shows that such an Ahead cap can be attached to the upper end of a front fork 50 of the bicycle and serves to axially fix a front assembly 51 for connecting the front fork 50 to a handlebar 52.

[0086] The functionality of such an Ahead cap is described, for example, in US 5,095,770 and US 8,662,517.

[0087] The locking module 2 can thus be connected to the coupling part 3 and, via the connecting element 4, to the assembly 5. The connecting element 4 enables a simple yet reliable and robust connection between the locking module 3 and the coupling part 3. By loosening the connecting element 4, the locking module 2 can also be removed and, if necessary, replaced, thus allowing for the variable use of a locking module 2 on a coupling part 3.

[0088] As this is shown Fig. 1 and Fig. 2A, Fig. As can be seen in Figure 2B, a fastening element 31, for example in the form of a screw, can be arranged on the coupling part 3, which has a head in a fastening opening in the area of ​​the support surface 301 and by means of which the coupling part 3 can be connected to the associated assembly 5, for example the front wheel fork 50 of a vehicle.

[0089] The connecting element 4 can be designed in very different ways.

[0090] This is how it is with a Fig. 3A, Fig. In the embodiment shown in 3B, the clamping device 41 is designed with an eccentrically acting clamping lever 410, which is designed to clamp the ends 402, 403 of the body 40 together in order to effect a clamping action on the body 40 of the connecting element 4.

[0091] At a Fig. 4A, Fig. In the embodiment shown in 4B, the clamping device 41 of the connecting element 4, on the other hand, has a clamping element 412 in the form of a screw, by means of which the ends 402, 403 of the body 40 can be clamped together.

[0092] Fig. 5A, Fig. Figure 5B shows views of an embodiment of a connecting element 4, in which the body 40 is formed by segments 404, 405 which are pivotally connected to each other about a pivot axis 406. In this case, the clamping device 41 has a clamping element 412 in the form of a screw, which can be manually turned by a user. The ends 402, 403 of the body 40 can then be clamped to each other via the clamping element 412.

[0093] At a Fig. 6A, Fig. In the embodiment shown in Figure 6B, the connecting element 4 has an annular body 40, but no clamping device. The ends 402, 403 of the body 40 face each other, but are free of each other. Due to the inherent elasticity of the body 40, the locking module 2 can be clamped to the coupling part 3 via the connecting element 4 by bringing the body 40, with its formed engagement sections 400, 401, into engagement with the clamping surfaces 230, 300.

[0094] However, a connection can also be made without tensioning by the body 40 encompassing the coupling section 23 on the one hand and the coupling section 30 on the other hand and connecting them in a form-fit manner without any significant tensioning effect.

[0095] In Fig. 7 and Fig. 8A, Fig. Figure 8B shows yet another embodiment of a connecting element 4, in which the connecting element 4 is formed by a bracket element in the form of a wire bracket. The wire bracket forms engagement sections 400, 401 in the form of wire struts, which can be brought into clamping engagement with the clamping surfaces 230, 300 on the coupling section 23 of the locking module 2 on the one hand and the coupling section 30 of the coupling part 3 on the other hand, as shown in Figure 8B. Fig. 7 in conjunction with Fig. 8A and Fig. 8B is evident.

[0096] Again, due to the truncated cone shape, a force redirection is effected at the clamping surfaces 230, 300 such that the coupling section 23 and the coupling section 30 are loaded against each other along the application direction A due to the clamping effect of the connecting element 4 and are thus pressed together with the bearing surfaces 231, 301.

[0097] The connecting element 4 in the form of the bracket element has, in the embodiment shown, Fig. 7 and Fig. 8A, Fig. 8B forms a U-shape or C-shape and encompasses the clamping surface 230, 300 circumferentially around the application direction A at an angle greater than 180°, so that a clamping effect is effected at least on two diametrically opposite sides of the clamping surfaces 230, 300 and the locking module 2 and the coupling part 3 are clamped together above it.

[0098] Fig. 9, Fig. 10 and Fig. 11A, Fig. Figure 11B shows views of the coupling part 3, for example in the form of an Ahead cap. In the illustrated embodiment, the coupling part 3 has a substantially rotationally symmetrical shape with a frustoconical clamping surface 300 and a bearing surface 301 that can be brought into contact with the coupling section 23 of the closure module 2 along the insertion direction A.

[0099] At a Fig. 12, Fig. 13A, Fig. In the embodiment shown in Figure 13B, a magnetic element 232, 303 is arranged on the coupling section 23 of the locking module 2 on the one hand and on the coupling section 30 of the coupling part 3 on the other. These magnetic elements have opposite poles N, S facing each other and thus attract each other magnetically. The magnetic elements 232, 303 thus facilitate the magnetic connection of the locking module 2 and the coupling part 3, simplifying the process of joining them.

[0100] With regard to the other design features of the coupling section 23, the coupling part 3 and the connecting element 4, the illustrated embodiment is otherwise identical to the embodiment according to Fig. 1 and Fig. 2A, Fig. 2B, so reference should be made to the preceding statements.

[0101] In the embodiments described above, the locking module 2 and the coupling part 3 can, if necessary, be rotated relative to each other about the insertion direction A in a position attached to each other, due to the rotationally symmetrical design of the coupling section 23 and the coupling section 30, so that the locking module 2 and the coupling part 3 can be connected to each other in different rotational positions and, if necessary, their position relative to each other can still be adjusted after the connection has been made via the connecting element 4.

[0102] At a Fig. 14, Fig. 15A, Fig. In the embodiment shown in Figure 15B, positive locking elements 233 in the form of pins are formed on the bearing surface 231 of the coupling section 23 of the locking module 2. These pins are designed to engage positive locking elements 304 in the form of engagement openings on the bearing surface 301 of the coupling section 30 of the coupling part 3. The positive locking elements 233 in the form of pins are offset from each other diametrically opposite to the insertion direction A on the bearing surface 231 of the coupling section 23. While the coupling section 23 has a pair of two positive locking elements 233, an integer multiple of pairs of positive locking elements 304 are formed in the form of engagement openings on the bearing surface 301 of the coupling section 30 of the coupling part 3, so that the locking module 2 can be attached to the coupling part 3 in discrete rotational positions offset from each other by the insertion direction A under engagement of the positive locking elements 233, 304 with each other.In a position joined together, the locking module 2 and the coupling part 3 are then fixed against rotation relative to each other.

[0103] At a Fig. 16, Fig. 17A, Fig. In the embodiment shown in Figure 17B, a centering device 234 in the form of an annular groove extending circumferentially around the insertion direction A is formed on the bearing surface 231 of the coupling section 23. This groove can be brought into a centering engagement with a centering device 305 in the form of an annular rib on the bearing surface 301. Because the centering devices 234 and 305 are rotationally symmetrical, the locking module 2 and the coupling part 3 can be adjusted and rotated relative to each other even in a joined position and, if necessary, even after the connection has been made via the connecting element 4. The coupling section 23 of the locking module 2 and the coupling section 30 of the coupling part 3 are centered relative to each other by the centering devices 234 and 305.

[0104] In the embodiments described above, the connecting element 4 is designed to engage both the coupling section 23 of the locking module 2 and the coupling section 30 of the coupling part 3 in order to establish a positive-locking and / or force-locking connection between the locking module 2 and the coupling part 3. The engagement sections 400 and 401 of the connecting element 4 engage clamping surfaces 230 and 300 of the coupling section 23 of the locking module 2 and the coupling section 30 of the coupling part 3 in order to clamp the locking module 2 and the coupling part 3 axially to each other along the insertion direction A.

[0105] While in the previously described embodiments the connecting element 4 engages around axially offset clamping surfaces 230, 300 of the locking module 2 and the coupling part 3, in a Fig.In the schematically illustrated embodiment 18, a connecting element 4, for example in the form of a wire clip, is connected to a coupling part 3 only with a clamping surface 300.

[0106] In the illustrated embodiment, the coupling part 3 can be inserted into a hollow cylindrical connecting sleeve 235 on a coupling section 23 of the locking module 2 in order to bring a bearing surface 231 inside the connecting sleeve 235 into contact with a bearing surface 301 on the coupling section 30 of the coupling part 3. Once the coupling part 3 has been inserted into the connecting sleeve 235, the connecting element 4 can be attached to the connecting sleeve 235 such that the connecting element 4, with radially inwardly projecting engagement sections 401, extends through diametrically opposed slot openings 236 on the connecting sleeve 235 and engages with the clamping surface 300 of the coupling part 3, thereby fixing the coupling part 3 to the coupling section 23.

[0107] In this embodiment, the connecting element 4 thus acts only on the coupling part 3 in a clamping manner, whereby a positive locking connection with the connecting sleeve 235 is additionally established and the coupling part 3 is thereby fixed to the coupling section 23.

[0108] The underlying idea of ​​the invention is not limited to the embodiments described above, but can also be realized in other ways.

[0109] The locking module and the coupling part can interact magnetically by having a magnetic arrangement on both. However, this is not mandatory. A connection between a locking module and a coupling part can also be established without magnetic interaction between them.

[0110] The connecting element can create tension between the locking module and the coupling part, although this is not mandatory. The connecting element can also simply establish a positive fit to secure the connection without creating an axial tension between the locking module and the coupling part.

[0111] The coupling section of the locking module and the coupling section of the coupling part can be designed with rotational symmetry, featuring rotationally symmetrical clamping surfaces extending circumferentially around the mounting direction. However, this is not mandatory. The coupling section and the coupling section, particularly in the area of ​​the clamping surfaces, can also be non-rotationally symmetrical, for example, angular, oval, or irregularly shaped.

[0112] A connecting device of the described type can be used to connect an assembly, for example an electronic assembly such as a mobile phone or a navigation device, to a vehicle, for example a bicycle. However, this is not a limitation. In principle, the connecting device can be used to connect any assemblies to one another.
