Description

Technical Field

[0001] The invention relates to a connector for mechanically fastening a first component to a second component. The first component has at least a first coupling groove with a first undercut effective in the groove depth direction. The second component has at least a second coupling groove with a second undercut effective in the groove depth direction.

[0002] The invention also relates to a component connector, comprising a first component having at least a first coupling groove. The groove opening of the first coupling groove is located in the contact surface of the first component. In addition, the first coupling groove has a first undercut effective in the groove depth direction. The component connector also comprises a second component having at least a second coupling groove. The groove opening of the second coupling groove is located in the contact surface of the second component. In addition, the second coupling groove has a second undercut effective in the groove depth direction. The component connector also comprises a connector of the type described in the introduction. Background Art

[0003] In this respect, the groove depth direction is understood to be the direction extending between the groove opening and the groove bottom. The groove opening is usually elongated. Otherwise, it is called a hole or a bore. Usually, the groove opening is opposite the groove bottom. For a groove that is limited on both sides along its travel direction, the groove opening is the only opening of the groove. For a groove that has one open end and two open ends along its travel direction, only the opening extending in the travel direction is considered to be the groove opening.

[0004] Thus, one or both open ends do not form a groove opening. The same applies to openings created by other design elements, such as transverse grooves or transverse drillings. In this respect, the direction parallel to the long side of the elongated groove opening is considered to be the direction of travel or extension. A groove whose groove depth varies along the direction of travel so that the groove depth at one or both ends of the groove decreases to zero is considered to be a groove defined on one or both sides.

[0005] Therefore, the undercut effective in the groove depth direction has a recess relative to the direction from the groove bottom to the groove opening. Therefore, the element engaged in the undercut cannot be pulled out of the groove in the groove depth direction because it forms a positive connection with the undercut.

[0006] Such undercuts and associated coupling grooves can be formed using known methods with known tools. The tools may be fixed or manually guided.

[0007] Connectors and component connections of the type described in the introduction are basically known. For example, they are used to mechanically fasten components consisting of wood to each other, i.e. to connect them. These components may be furniture components. Alternatively, these components may be structural elements of wooden buildings, for example from the construction industry. However, it should be understood that the connectors and component connections described in the introduction are not limited to a specific material class or a specific field of application. They can also easily be used for components consisting of synthetic materials, metals, ceramics, stone, etc.

[0008] In all possible applications, an undercut that is effective in the direction of the associated groove depth has the advantage that the components can be fastened to one another in a very reliable manner. In this case, a form-fitting connection can be established with the aid of the undercut. This applies in particular in comparison to a coupling groove without any such undercut. Summary of the invention

[0009] The object of the present invention is to provide a connector and an allocating component connection which are simple and cost-effective and in which the connection is known to be very reliable.

[0010] The above-mentioned purpose is achieved by a connector for mechanically fastening a first component to a second component. The first component has at least a first coupling groove, which has a first undercut effective in the groove depth direction. The second component has at least a second coupling groove, which has a second undercut effective in the groove depth direction. The connector is two-dimensional or flat strip-shaped. In addition, the connector has a first engaging element for anchoring in the first undercut and a second engaging element for anchoring in the second undercut. In addition, the connector includes a pusher for positioning at least a portion of the first engaging element in the first undercut and positioning at least a portion of the second engaging element in the second undercut. The pusher is movably connected to the first engaging element and the second engaging element. In this regard, the first undercut can be arranged in the region of the groove bottom of the first coupling groove. Alternatively or additionally, the second undercut can be arranged in the region of the groove bottom of the second coupling groove. By means of its two-dimensional shape or flat strip shape, the connector is particularly suitable for connecting components via the coupling groove. In the installed state of the connector, the thickness direction of the connector corresponding to the minimum spatial dimension of the connector extends along the groove width direction (i.e., perpendicular to the direction of travel of the groove and perpendicular to the groove depth direction). Therefore, the connector can be effectively used for component connectors that can only fill a relatively small installation space. This is particularly suitable for using the connector to connect two-dimensional components. In such applications, in the installed state, the thickness direction of the connector extends parallel to the thickness direction of the two-dimensional component. In addition, the advantage of the two-dimensional shape or flat strip shape is that the effective holding force between the connector and each of the first and second components is effectively distributed in a relatively large part of the first and second components. The holding force is introduced into the corresponding component via the line contact between the connector and the first and / or second component or via the surface contact between the connector and the first and / or second component. Therefore, relatively small mechanical stress is generated in the first and second components. In addition, a linear or face-to-face engagement can be established between the connector and the first undercut and / or the second undercut. This results in a particularly firm and reliable fastening of the first and second components to each other. This is due to the fact that the connector has a first engagement element and a second engagement element and provides a single pusher for the two engagement elements. In this regard, the pusher can position the engagement elements in the respective assigned undercuts, and can also position the engagement elements in the respective assigned undercuts. Therefore, in the installed state, the connector is anchored in the first and second components at the same time. Therefore, the engaging element can also be referred to as an anchoring element or jaw. On the one hand, such a connector is constructed in a structurally simple manner, which facilitates cost-effective production. On the other hand, it is simple to use, since the components can be fastened to each other quickly and easily with the aid of such a connector.

[0011] In this case, the kinematic connection of two elements should be understood to mean that the two elements can only move interdependently. This means that, in the case where the first element of the two elements moves, the second element of the two elements also moves. The movement of the second element may be limited by the movement of the first element. The movement of the two elements can be the same or different. In the first example of kinematic connection, the first element and the second element are fixedly connected. Therefore, they always move together. In the second example of kinematic connection, the first element and the second element are movably connected. This means that the first element and the second element can move relative to each other, but these movements are interdependent. Specifically, for the first engagement element, the second engagement element and the pusher of the kinematic connection, this means that the pusher can be fixedly connected to the first engagement element and / or the second engagement element. Alternatively, the first engagement element and / or the second engagement element can be movably connected to the pusher. In this alternative, the first engagement element and / or the second engagement element can therefore move relative to the pusher, wherein the movement of the first engagement element and / or the second engagement element preferably depends on the movement of the pusher.

[0012] It should be noted that the effects and advantages described with reference to the two-dimensional shape or flat strip shape are particularly evident with respect to cylindrical or round bar connectors, since two-dimensional or flat strip connectors can be connected to the components to be connected over a relatively large portion of them compared thereto. In this respect, a specified component thickness generally means that at least one dimension of the connector cannot be increased arbitrarily. For cylindrical or round bar connectors, this is usually the diameter. For two-dimensional or flat strip connectors, only the associated thickness is limited by the component thickness. The remaining dimensions can be adjusted essentially freely.

[0013] Furthermore, it should be understood that the first and second engagement elements must at least in the mounted state and at least partially protrude relative to the remaining components of the two-dimensional or flat strip-shaped connector in order to be able to engage in the allocated undercut. Preferably, the first and second engagement elements protrude from the connector parallel to the thickness direction of the connector.

[0014] Furthermore, due to the kinematic coupling, the connector according to the invention is always designed as a cohesive unit. This applies to the entire use phase of the connector. This means that once the connector is made, it forms a cohesive unit, regardless of whether it is specifically used to mechanically connect parts. All parts of the connector are thus held together in a captive manner. This makes it easier to manipulate the connector.

[0015] According to a variant, the first engagement element has a first retaining surface for abutting against the first undercut, and the second engagement element has a second retaining surface for abutting against the second undercut. The first retaining surface and the second retaining surface extend in parallel. Such a connector is constructed in a simple manner. In addition, a stable component connection can be established using such a connector.

[0016] In one example, the connector is symmetrically constructed. This means that the connector is constructed so that, selectively, the first engagement element can be anchored in the first undercut and the second engagement element can be anchored in the second undercut, or the first engagement element can be anchored in the second undercut and the second engagement element can be anchored in the first undercut.

[0017] In one variant, the first engagement element and the second engagement element are made of a metallic material. This allows the engagement elements to be anchored with particularly high reliability in the associated coupling groove and in particular in the undercut present at this location.

[0018] According to one embodiment, the first engaging element and / or the second engaging element is fixedly connected to the pushing body. The first engaging element and / or the second engaging element can be made integral with the pushing body, for example by a casting or injection molding method. Alternatively, the first engaging element and / or the second engaging element can be connected to the pushing body during the manufacture of the connector, for example by a suitable joining method. In both variants, a connector is provided, which is particularly simple in structure and can therefore be produced in a particularly cost-effective manner. The installation activities for producing the connector are limited to installing the first engaging element and / or the second engaging element, or can be omitted completely.

[0019] The pusher can have the shape of a disk portion or the shape of a disk. Therefore, the pusher is constructed in a simple manner and can be produced at low cost. In addition, when it comes to positioning the first engagement element and / or the second engagement element in the undercut of each distribution, this shape is advantageous. The pusher of disk portion shape or disk shape has relatively few geometric elements, such as angles and edges, which may not collide with the elements of the first component and / or the second component during the movement of the pusher, and may be blocked by them. On the contrary, this shape of the pusher is advantageous, because when the pusher contacts with the first component and / or the second component, the pusher slides against the components and therefore moves in the direction of the desired position. In this respect, the actuating element of the actuating body (that is, the element via which the actuating force or the actuating torque can be introduced into the actuating body) can be arranged centrally with the disk portion shape or arranged centrally with the disk shape. This causes the force curve to be uniform, ideally symmetrical.

[0020] In a variant, at least one of the first engagement element and the second engagement element is designed as an arched protrusion. Such an engagement element can be positioned in the allocated undercut in a particularly simple manner. In addition, such an engagement element is particularly suitable for cooperating with an arched recessed portion and an arched undercut. In such a configuration, the engagement element can be easily introduced into the respective allocated undercut by the rotational movement of the connector.

[0021] According to one embodiment, in addition to the first engagement element and the second engagement element, the connector also includes a third engagement element and a fourth engagement element. Preferably, the third engagement element is configured to be anchored in the third undercut. Preferably, the first coupling groove has a third undercut, wherein the third undercut is effective in the groove depth direction of the first coupling groove. In addition, the fourth engagement element is preferably configured to be anchored in the fourth undercut. Advantageously, the second coupling groove has a fourth undercut, wherein the fourth undercut is effective in the groove depth direction of the second coupling groove. The third engagement element can be arranged at the same end of the connector as the first engagement element. Alternatively or additionally, the fourth engagement element can be arranged at the same end of the connector as the second engagement element. A connector is provided that can be anchored in the first coupling groove and / or the second coupling groove with particularly high reliability.

[0022] According to a variant, the third engagement element has a third retaining surface for abutting against the third undercut, and the fourth engagement element has a fourth retaining surface for abutting against the fourth undercut. The third retaining surface and the fourth retaining surface extend in parallel. Such a connector is constructed in a simple manner. In addition, a stable component connection can be established using such a connector. Preferably, the third retaining surface and the fourth retaining surface also extend parallel to the first retaining surface and the second retaining surface.

[0023] In one example, the connector is also symmetrically constructed. This means that the connector is constructed so that, selectively, the third engagement element can be anchored in the third undercut and the fourth engagement element can be anchored in the fourth undercut, or the third engagement element can be anchored in the fourth undercut and the fourth engagement element can be anchored in the third undercut.

[0024] Preferably, the connector comprising the first, second, third and fourth engagement elements is symmetrically configured so that each engagement element can be anchored in each undercut. Such a connection can therefore be used in four different orientations. Therefore, the user does not need to consider the orientation in which he / she inserts the connector into the coupling groove. This makes it easier to use the connector.

[0025] In one design alternative, one or more engagement elements have at least one introduction bevel. This facilitates the introduction of the respective engagement element into the associated undercut.

[0026] In a variant, at least one of the engagement elements is coupled to the pusher body via a gear unit. The gear unit ensures that the engagement element can be moved in a specific manner depending on the pusher body. Thus, pushing one of the engagement elements by means of the pusher body results in a specified movement of the engagement element, so that it can reliably and in a specified manner engage into the allocated undercut.

[0027] By means of the gear unit, the first engagement element and / or the second engagement element can be selectively moved to a retracted position or an extended position, for example in the thickness direction of the connector. This is achieved with a high degree of reliability and precision. The retracted position can be particularly suitable for easily introducing the connector into the first coupling groove and / or the second coupling groove and / or easily removing the connector from the first coupling groove and / or the second coupling groove. The extended position can be configured to anchor the first engagement element and / or the second engagement element in the respectively allocated undercut.

[0028] Alternatively or additionally, the first engagement element and / or the second engagement element can be selectively transferred to a retracted position or an extended position, for example, along the longitudinal direction of the connector, which extends transversely to the thickness direction of the connector, and in the installed state, extends along the groove depth direction. This is also achieved with a high degree of reliability and precision. The extended position can be particularly suitable for easily introducing the connector into the first coupling groove and / or the second coupling groove and / or easily removing the connector from the first coupling groove and / or the second coupling groove. The extended position can adapt to the groove depth of the first coupling groove and the second coupling groove, so that when the connector is inserted into the first coupling groove and the second coupling groove and presents the extended position, the first component and the second component maintain a defined distance from each other. This distance corresponds to when the connector is transferred to the retracted position, the first component and the second component move toward each other thereon until they are close to each other via the corresponding contact surface, i.e., the distance. It should be understood that the first engagement element and the second engagement element must be anchored in the undercuts assigned to each other so as to move toward or away from each other. The retracted position can be configured so that the first component and the second component fastened to each other by means of the connector can be placed against each other. They can be placed against each other in this manner by applying a force.

[0029] According to an alternative, the pusher is movably coupled to at least one of the first coupling element and the second coupling element via a gear mechanism. A gear mechanism is understood to be a gear unit comprising at least one toothed portion for motion coupling. The toothed portion does not necessarily have to extend completely around the circumference of the wheel-shaped element. The toothed portion can also be designed as a rack or an arcuate toothed segment. One or more gear mechanisms can be provided. The gear mechanisms have a simple and robust structure. In addition, with a compact structure, they can transmit relatively large forces and torques. This means that at least one extended position and at least one retracted position can be achieved in a simple manner with the aid of a gear mechanism.

[0030] In an alternative, the pusher is movably coupled to at least one of the first engagement element and the second engagement element via a primary cam mechanism. In this respect, the cam mechanism is designated as primary only for ease of illustration. There is no suggestion that there are many cam mechanisms. The cam mechanism has a simple and robust structure. This also allows for an uneven transmission between the pusher and the engagement element. This means that at least one extended position and at least one retracted position can be achieved in a simple manner by means of the primary cam mechanism.

[0031] The main cam mechanism may have a cam surface arranged on the pusher. In addition, the main cam mechanism may have a relative surface assigned to the cam surface, which is arranged on at least one of the first engaging element and the second engaging element, or is operably connected to at least one of the first engaging element and the second engaging element. Therefore, the relative surface is directly arranged on the assigned engaging element or on an intermediate element that is movably located between the pusher and the assigned engaging element. In this regard, when the relative surface is arranged to contact the cam surface so as to form the main cam mechanism, the relative surface is assigned to the cam surface. The cam surface and the relative surface can be any shape, such as curved, so as to achieve any desired but specified transmission between the movement of the pusher and the movement of the assigned engaging element.

[0032] The main cam mechanism may also have a cam surface arranged on the pusher and a counter surface assigned to the cam surface and arranged on a coupling element, wherein the coupling element movably couples the pusher to at least one of the first engagement element and the second engagement element. The coupling element may be used to bridge the distance between the pusher and the assigned engagement element, for example. In addition, the coupling element may be used to arrange the cam surface and the counter surface in a space-saving manner.

[0033] In one example, the coupling element is a coupling slide.

[0034] The cam surface of the main cam mechanism and the relative surface of the distribution can be self-locking at least in a specified relative position. In this way, the engagement element of the distribution can be kept in a specified relative position relative to the pusher by means of the main cam mechanism.

[0035] In another embodiment, the pusher is movably coupled to at least one of the first engagement element and the second engagement element via an auxiliary cam mechanism. In this respect, the designation of the cam mechanism as auxiliary is merely for ease of description. There is no implication that there are many cam mechanisms, wherein, in the case where the connector comprises a main cam mechanism and an auxiliary cam mechanism, there are of course at least two cam mechanisms. The cam mechanism has a simple and robust structure. This also allows for uneven transmissions between the pusher and the engagement element. This means that at least one extended position and at least one retracted position can be achieved in a simple manner with the aid of the auxiliary cam mechanism.

[0036] The auxiliary cam mechanism may have a cam surface arranged on the pusher. In addition, the auxiliary cam mechanism may have a relative surface assigned to the cam surface, which is arranged on at least one of the first engaging element and the second engaging element, or is operably connected to at least one of the first engaging element and the second engaging element. Therefore, the relative surface is directly arranged on the assigned engaging element or on an intermediate element that is movably located between the pusher and the assigned engaging element. In this regard, when the relative surface is arranged to contact the cam surface so as to form the auxiliary cam mechanism, the relative surface is assigned to the cam surface. The cam surface and the relative surface can be any shape, such as curved, so as to achieve any desired but specified transmission between the movement of the pusher and the movement of the assigned engaging element.

[0037] The cam surface of the auxiliary cam mechanism and the relative surface of the distribution can be self-locking at least in the specified relative position. In this way, the engagement element of the distribution can be kept in the specified relative position relative to the pusher by means of the auxiliary cam mechanism.

[0038] In a variant, the main cam mechanism and the auxiliary cam mechanism are adapted to each other so that when the first component and the second component are mounted on each other, the first engaging element and the second engaging element are first transferred to the extended position in the thickness direction of the connector. Therefore, the first engaging element and the second engaging element are anchored in the undercuts assigned to each other. Then, the first engaging element and the second engaging element can be transferred to the retracted position in the longitudinal direction of the connector, and the longitudinal direction extends transversely to the thickness direction of the connector, and in the installed state, extends in the groove depth direction. Therefore, the first component and the second component are placed against each other. When the main cam mechanism is used to move the first engaging element and the second engaging element to the extended position in the thickness direction of the connector, and the auxiliary cam mechanism is used to move the first engaging element and the second engaging element to the retracted position in the longitudinal direction, the cam surface and the relative surface forming the main cam mechanism must first interact with each other. Only in this way, the cam surface and the relative surface forming the auxiliary cam mechanism interact with each other. When the first component and the second component are disassembled from each other, the steps and processes described are implemented in reverse order.

[0039] In a design alternative, the connector comprises a carrier, wherein the pusher can be rotatably mounted on the carrier around an axis of rotation. The pusher can be held in a defined position relative to the assigned engagement element by means of the carrier. Such a connector is particularly reliable in its function. In addition, the carrier can be used to position the connector in the first coupling groove and / or the second coupling groove. In the case where the carrier is used to position the connector in both the first coupling groove and the second coupling groove, the first component and the second component can be positioned relative to each other by means of the carrier. The carrier can also be used to introduce force into the connector or obtain force from the connector on a relatively large surface. Therefore, the connector can connect the first component and the second component via a high retaining force, however, this only produces relatively low mechanical stress in the first component and the second component. Preferably, the carrier is designed to have two shells, so that the pusher can be at least partially accommodated between the two shells of the carrier.

[0040] At least one of the first engaging element and the second engaging element can be mounted on the carrier in a translationally displaceable manner. This translational displaceability can be used to engage the engaging element with the undercut. Alternatively or additionally, the translational displaceability can be used to move the first component and the second component toward each other. Therefore, the first component and the second component can be placed against each other in a reliable manner.

[0041] At least one of the first and second joining elements can also be connected to the carrier in an articulated manner. The articulated joint is formed, for example, by means of a film hinge. Thus, the joining element is held on the carrier in a captive manner, but is still movable.

[0042] In another embodiment, the pusher body comprises at least one pusher arm that can rotate around the axis of rotation. Such a pusher arm can be used to accurately and reliably apply the actuation force to the allocated engagement element. In addition, the pusher arm can form a lever element, by means of which a relatively small force can be converted into a relatively large force.

[0043] The push arm can be made of a metal material. Such a push arm is suitable for particularly high forces and is particularly durable.

[0044] At least one cam surface can be arranged on the free end of the push arm. The free end should be understood as an end facing away from the pivot point of the push arm. Therefore, the cam mechanism assigned to the cam surface is actuated by the movement of the push arm.

[0045] In an exemplary embodiment, at least part of the pusher is bolt-shaped. Such a pusher is particularly compact. Preferably, the center axis of the bolt coincides with the rotation axis of the pusher.

[0046] At least one cam surface can be arranged on the outer circumference of the bolt-shaped portion of the pusher.Therefore, the cam mechanism assigned to the cam surface is actuated by the movement of the pusher.

[0047] In one embodiment, the pusher has an actuating element for introducing the actuating force and / or the actuating torque. Therefore, the actuating force and / or the actuating torque can be simply and reliably introduced into the pusher. In one example, the actuating element is designed as an engagement opening. The engagement opening can be suitable for an actuating tool, which can be engaged in the engagement opening to actuate the pusher. For example, the engagement opening has a hexagonal cross section, which is configured to receive one end of an Allen key. The engagement opening can be designed as a through opening or a blind opening.

[0048] Preferably, in order to mount the first component and the second component on each other, a rotation of the actuating tool of less than 180 degrees, in particular less than 170 degrees, more particularly less than 160 degrees is required. The connector can thus be conveniently actuated by means of the actuating tool. Thus, a conversion tool is rarely or never required.

[0049] The object is also achieved by means of a connector having a length measured in the insertion direction, a width measured transversely to the insertion direction, and a thickness measured transversely to the insertion direction. The thickness is always smaller than the width. In addition, the ratio of width to length is 1 to 3, preferably 1.4 to 2. The connector can be constructed according to one or more of the aforementioned examples and embodiments, but it is not necessary to do so. Therefore, for a two-dimensional or flat strip connector, the length, width and thickness can be determined by defining the minimum external dimension as the thickness. Then, the external dimension oriented in the insertion direction is defined as the length, and the remaining external dimension is defined as the width. The insertion direction is the direction along which the connector is inserted into one or more coupling grooves to connect the assigned components. Therefore, such connectors are relatively short in the length direction. Therefore, they can be used to connect components that only have relatively small space in the length direction. This is particularly true for flat components or corner connections.

[0050] The object is also achieved by a component connector. The component connector comprises a first component having at least a first coupling groove, the groove opening of the first coupling groove being located in the first contact surface of the first component and the first coupling groove having a first undercut effective in the groove depth direction. The component connector also comprises a second component having at least a second coupling groove, the groove opening of the second coupling groove being located in the second contact surface of the second component and the second coupling groove having a second undercut effective in the groove depth direction. In addition, the component connector comprises a connector according to the present invention. Part of the connector is arranged in the first coupling groove, and part of it is arranged in the second coupling groove. The first engaging element of the connector engages in the first undercut. The second engaging element of the connector engages in the second undercut. In addition, the first contact surface of the first component and the second contact surface of the second component contact each other. Therefore, the part of the connector accommodated in the first coupling groove and the part of the connector received in the second coupling groove complement each other to form the connector as a whole. The undercuts are preferably each arranged in the region of the groove bottom of the associated groove. Therefore, the first component and the second component are fastened to each other in an extremely reliable manner. In addition, since the connector is two-dimensional or flat strip-shaped, this component connector saves space.

[0051] In this regard, at least one of the first coupling groove and the second coupling groove may be larger than the size of the portion of the connector received in the first coupling groove or the second coupling groove along the direction of travel of the corresponding assigned coupling groove. Therefore, the corresponding portion of the connector can be displaced a certain distance in the assigned coupling groove along the direction of travel. This allows the first component and the second component to be fastened to each other in different relative positions along the direction of travel of the first coupling groove or the second coupling groove. This can be used for tolerance compensation. For example, the first component and the second component can be accurately connected to each other in this way, although at least one of the first coupling groove and the second coupling groove is affected by a position deviation or positioning error.

[0052] The first part and the second part can be abutted against each other in any manner. In a preferred variant, the abutment arrangement is designed as a corner joint, a butt joint or a bevel joint. In particular, in the last case, the connector is given a two-dimensional shape or a flat strip shape, because this shape means that it can also be used for bevel joints.

[0053] An access channel for the tool can be provided on the first component and / or on the second component, wherein the access channel extends from the outer surface of the workpiece into the first coupling groove and / or into the second coupling groove. The pusher, in particular the actuating element of the pusher, can be reliably reached via such an access channel. Thus, the connector can be actuated in a reliable manner.

[0054] According to a variant, the access channel is open in the direction of the assigned contact surface. Such an access channel may also be referred to as a groove. It extends transversely to the assigned coupling groove. In order to produce such a transverse groove in a specified relative position relative to the coupling groove, no drilling template is required, since the groove can be produced starting from the contact surface. Thus, the transverse groove can be easily produced, for which purpose a routing machine or a dowel milling machine can be used. Of course, the transverse groove and the first coupling groove and the second coupling groove can also be produced by an industrial CNC milling machine.

[0055] Preferably, the actuating element of the connector is positioned at the coupling groove-side end of the entry channel. Therefore, the actuating element can be easily reached with an associated tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] Figure 1A component connection 10 according to a first embodiment is shown.

[0084] The component connection includes a first component 12 and a second component 14 .

[0085] A first contact surface 16 is provided on the first component 12 .

[0086] The second component 14 includes a second contact surface 18 .

[0087] In a state where the first component 12 and the second component 14 are fastened to each other, the first contact surface 16 and the second contact surface 18 are in contact with each other (see also Figure 3 and Figure 4 ).

[0088] The first component 12 further comprises two positioning grooves 20 a , 20 b , whose groove openings 22 a , 22 b are located in the first contact surface 16 .

[0089] Consequently, the respectively assigned groove depth directions 24 a , 24 b of the positioning grooves 20 a , 20 b extend perpendicularly to the first contact surface 16 .

[0090] In a plan view of the first contact surface 16, the two positioning grooves 20a, 20b each have a substantially rectangular cross section, wherein the corners of the rectangular cross section are rounded. The direction parallel to the long side of the rectangular cross section can be described as the direction of travel or extension of the respective positioning grooves 20a, 20b.

[0091] The groove depth, ie the dimension of the positioning grooves 20a, 20b in the respectively assigned groove depth direction 24a, 24b, is constant in both positioning grooves 20a, 20b in the running direction.

[0092] The second component 14 likewise comprises two positioning grooves 26 a , 26 b , whose groove openings 28 a , 28 b are located in the second contact surface 18 .

[0093] The positioning groove 26 a is arranged such that the groove opening 28 a is opposite to the groove opening 22 a in the mounted state of the first component 12 and the second component 14 .

[0094] The positioning groove 26 b is arranged such that the groove opening 28 b is opposite to the groove opening 22 b in the mounted state of the first component 12 and the second component 14 .

[0095] Correspondingly, the respectively assigned groove depth directions 30 a , 30 b of the positioning grooves 26 a , 20 b extend perpendicularly to the second contact surface 18 .

[0096] In a plan view of the second contact surface 18, the two positioning grooves 26a, 26b each have a substantially rectangular cross section, wherein the corners of the rectangular cross section are rounded. A direction parallel to the long side of the rectangular cross section can be designated as a travel direction or extension direction of the corresponding positioning grooves 26a, 26b.

[0097] The groove depth, ie the dimension of the positioning grooves 26a, 26b in the respectively assigned groove depth direction 30a, 30b, is constant in both positioning grooves 26a, 26b in the running direction.

[0098] The component connector 10 further comprises two positioning elements 32a, 32b. Figure 1 In the embodiment of FIG. 5 , the positioning elements 32 a , 32 b are designed as so-called flat pins.

[0099] In an advantageous manner, the positioning element 32a is arranged in the positioning recess 20a, 26a with an exact fit, ie without any play, and the positioning element 32b is arranged with play in the direction of travel or extension of the positioning recess 20b, 26b.

[0100] from Figure 2 As can be seen from the view of , the positioning elements 32a, 32b can also be designed as so-called round pins. For the rest, Figure 2 The component connector 10 and Figure 1 The component connecting piece 10 corresponds to.

[0101] When the first component 12 and the second component 14 are fastened to each other, portions of the positioning element 32a are received in the positioning grooves 20a and 26a, wherein the portions of the positioning element 32a received in the positioning grooves 20a, 26a complement each other to form the entire positioning element 32a.

[0102] Portions of the positioning element 32b are received in the positioning groove 20b and the positioning groove 26b, respectively, wherein the portions of the positioning element 32b received in the positioning grooves 20b, 26b complement each other to form the entire positioning element 32b.

[0103] The positioning elements 32 a , 32 b have the effect that the first component 12 and the second component 14 can be fastened to each other only in a specified relative position.

[0104] The first component 12 also has a first coupling groove 34 , the groove opening 36 of which is located in the first contact surface 16 (see also Figure 3 and Figure 4 ).

[0105] A groove depth direction 38 of the first coupling groove 34 extends perpendicularly to the first contact surface 16 .

[0106] However, compared with the positioning grooves 20a, 20b, 26a, 26b, the groove bottom 40 of the first coupling groove 34 is configured as a part of the outer circumferential surface of the cylinder. Therefore, the groove depth of the first coupling groove 34 is not constant. Instead, the groove depth is zero at the first end 42a of the first coupling groove 34 along the travel direction, then continuously increases along the travel direction until the deepest point, and then continuously decreases, so that the groove depth is zero at the second end 42b of the first coupling groove 34 opposite to the first end along the travel direction.

[0107] The central axis M of the cylindrical outer peripheral surface forming the groove bottom 40 is located outside the first member 12 .

[0108] The first coupling groove 34 furthermore has a first undercut 44 which is effective in the groove depth direction 38 and is arranged in the region of the groove bottom 40 .

[0109] In the illustrated embodiment, the first undercut is designed as a transverse groove extending along the groove bottom 40 , wherein the groove depth direction 46 of the transverse groove is parallel to the center axis M.

[0110] Furthermore, the first coupling groove 34 has a third undercut 48 which is effective in the groove depth direction 38 and is arranged in the region of the groove bottom 40. The third undercut 48 is provided on the wall of the first coupling groove 34 opposite the first undercut 44.

[0111] In the illustrated embodiment, the third undercut is designed as a transverse groove extending along the groove bottom 40 , wherein the groove depth direction 50 of the transverse groove is parallel to the center axis M.

[0112] Note that designating the undercut as the third undercut is merely for ease of explanation and does not imply that there are multiple undercuts.

[0113] The second component 14 has a second coupling groove 52 , the groove opening 54 of which is located in the second contact surface 18 (see also Figure 3 and Figure 4 ).

[0114] In a state in which the first component 12 and the second component 14 are fastened to each other, the groove opening 54 of the second coupling groove is arranged such that it is opposed to the groove opening 36 of the first coupling groove 34 .

[0115] A groove depth direction 56 of the second coupling groove 52 extends perpendicularly to the first contact surface 18 .

[0116] As has been described with reference to the first coupling groove 34, the groove bottom 58 of the second coupling groove 52 is formed as a part of the cylindrical outer peripheral surface. Therefore, the groove depth of the second coupling groove 52 is not constant. Instead, the groove depth is zero at the first end 60a of the second coupling groove 52 in the traveling direction, then increases continuously in the traveling direction until the deepest point, and then decreases continuously, so that the groove depth is zero at the second end 60b of the second coupling groove 52 opposite to the first end 60a in the traveling direction.

[0117] The central axis M of the cylindrical outer peripheral surface forming the groove bottom 58 is located in the second member 14 , wherein the groove bottom 58 protrudes perpendicularly to the contact surface 18 .

[0118] In the illustrated embodiment, when the first component 12 and the second component 14 are fastened to each other, the center axes M of the groove bottom 40 of the first coupling groove 34 and the groove bottom 58 of the second coupling groove 52 coincide.

[0119] The second coupling groove 52 also has a second undercut 62 which is effective in the groove depth direction 56 and is arranged in the region of the groove bottom 58 .

[0120] In the illustrated embodiment, the second undercut 62 is designed as a transverse groove extending along the groove bottom 58 , wherein a groove depth direction 64 of the transverse groove is parallel to the center axis M.

[0121] Furthermore, the second coupling groove 52 has a fourth undercut 66 which is effective in the groove depth direction 56 and is arranged in the region of the groove bottom 58. The fourth undercut 66 is provided on the wall of the second coupling groove 52 which is opposite to the second undercut 62.

[0122] In the illustrated embodiment, the fourth undercut 66 is designed as a transverse groove extending along the groove bottom 58 , wherein a groove depth direction 68 of the transverse groove is parallel to the center axis M.

[0123] Furthermore, an access channel 70 for a tool 72 is provided on the second component 14 .

[0124] In the figure, the tool 72 is designed as a so-called Allen key, which is to be understood merely as an example.

[0125] It is emphasized that the tool 72 is merely shown to improve understanding of the component connection 10 and does not form a part of the component connection 10 .

[0126] The access channel 70 extends from a workpiece outer surface 74, which in the example shown vertically adjoins the second contact surface 18, until entering the second coupling groove 52. In other words, the access channel 70 penetrates the side wall of the second coupling groove 52.

[0127] Thus, the tool 72 can reach a connector to be described at a later stage, which is arranged in the second coupling groove 52 , via the access channel 70 .

[0128] Furthermore, the inlet channel 70 is open in the direction of the second contact surface 18 .

[0129] Therefore, the entry channel 70 can be considered as a groove extending transversely to the second coupling groove 52 , wherein the travel direction of the groove forming the entry channel is arranged perpendicular to the travel direction of the second coupling groove 52 , and the groove opening of the groove forming the entry channel 70 is located within the second contact surface 18 .

[0130] In the illustrated embodiment, the central axis M extends through the entry passage 70 .

[0131] The component connection 10 further comprises a connector 76 according to the first embodiment. Figure 5 Shown separately in.

[0132] The connector 76 is generally two-dimensional.

[0133] It includes a first engaging element 78 configured to anchor the connector 76 in the first undercut 44 , a second engaging element 80 configured to anchor the connector 76 in the second undercut 62 , a third engaging element 82 configured to anchor the connector 76 in the third undercut 48 , and a fourth engaging element 84 configured to anchor the connector 76 in the fourth undercut 66 .

[0134] In addition, the connector 76 has a pusher 86. Figure 5 In the first embodiment shown, the pusher 86 is in the shape of a disk segment.

[0135] An actuating element 88 is arranged on the pusher 86 .

[0136] In the embodiment shown, the actuating element 88 is designed as a through opening with a hexagonal cross section. The cross section is dimensioned to be able to cooperate with the tool 72 .

[0137] When the disc portion shape of the actuating element 88 is conceptually extended to form a complete disc, the actuating element 88 is arranged centrally in the pusher 86. In other words, the center axis of the conceptually extended pusher 86 and the center axis of the actuating element 88 coincide.

[0138] The first engaging element 78 , the second engaging element 80 , the third engaging element 82 and the fourth engaging element 84 are movably coupled to the pushing body 86 because the first engaging element 78 , the second engaging element 80 , the third engaging element 82 and the fourth engaging element 84 are fixedly connected to the pushing body 86 .

[0139] In the embodiment shown, the first engagement element 78 , the second engagement element 80 , the third engagement element 82 , the fourth engagement element 84 and the pusher 86 are produced in one piece, for example as an injection-molded component.

[0140] The first engagement element 78 , the second engagement element 80 , the third engagement element 82 and the fourth engagement element 84 are each designed as an arcuate protrusion on the pusher 86 .

[0141] The curvature of the first 78 , second 80 , third 82 and fourth 84 engagement elements each substantially corresponds to the curvature of the transverse groove forming the assigned undercut 44 , 48 , 62 , 66 .

[0142] The first engagement element 78 and the second engagement element 80 protrude from the same side of the disk-shaped pusher 86. Figure 5 , the side of the pusher body 86 is forward.

[0143] The first engagement element 78 and the second engagement element 80 are arranged diametrically opposite one another with respect to a center axis of the actuating element 88 .

[0144] The third engagement element 82 and the fourth engagement element 84 also protrude from the same side of the disk-shaped pusher 86. However, this side is opposite to the side from which the first engagement element 78 and the second engagement element 80 protrude.

[0145] The third engagement element 82 and the fourth engagement element 84 are also arranged diametrically opposite one another with respect to the center axis of the actuating element 88 .

[0146] In addition, the first engagement element 78 and the third engagement element 82 are arranged adjacent to each other in a direction perpendicular to the disk-shaped pusher 86 (ie, parallel to the central axis of the actuating element 88). The same applies to the second engagement element 80 and the fourth engagement element 84.

[0147] In the component connection 10 , the first component 12 and the second component 14 are fastened to each other by means of the connector 76 .

[0148] Therefore, in order to form the component connection 10, the connector is first inserted into the second coupling groove 52, such as Figure 1 shown.

[0149] In this state, the actuating element 88 is positioned at the coupling groove-side end of the inlet channel 70 .

[0150] Furthermore, the first engagement element 78 and the second engagement element 80 engage into the second undercut 62. The first engagement element 78 and the second engagement element 80 are dimensioned such that they can be received in the groove forming the second undercut 62.

[0151] The third engaging element 82 and the fourth engaging element 84 engage in the fourth undercut 66 .

[0152] The third engagement element 82 and the second engagement element 84 are also sized such that they may be received in the recess forming the fourth undercut 66 .

[0153] The first component 12 and the second component 14 are then inserted one into the other using the positioning elements 32a, 32b so that the first contact surface 16 and the second contact surface 18 are in contact with each other.

[0154] The tool 72 is now brought into engagement with the actuating element 88 via the access channel 70 and the connector 76 is rotated substantially 90 degrees by means of the tool 72. In the embodiment shown, this is effected clockwise.

[0155] Therefore, the first engagement element 78 and the second engagement element 82 migrate into the first coupling groove 34 .

[0156] More precisely, the first abutment element 78 extends into the first undercut 44 and the third abutment element 82 extends into the third undercut 48 .

[0157] At the same time, the second engagement element 80 migrates into the second undercut 62 in the direction of the deepest point of the second coupling groove 52. The fourth engagement element 84 likewise migrates into the second undercut 66 in the direction of the deepest point of the second coupling groove 52.

[0158] It should be understood that this may be reversed when the connector 76 is rotated in the opposite direction (ie, counterclockwise) by means of the tool 72 .

[0159] Therefore, since the actuating element 88 is arranged on the pushing body 86, the pushing body 86 is used to position the first engaging element 78 in the first undercut 44, the second engaging element 80 in the second undercut 62, the third engaging element 82 in the third undercut 48, and the fourth engaging element 84 in the fourth undercut 66.

[0160] The first component 12 and the second component 14 are connected by means of a connector 76 .

[0161] Part of the connector 76 is arranged in the first coupling groove 34, and part of the connector 76 is arranged in the second coupling groove 52. At the same time, the connector 76 is completely received in the first coupling groove 34 and the second coupling groove 52.

[0162] In this respect, the dimensions of the first coupling groove 34, the second coupling groove 52 and the connector 76 can be adapted to one another so that the connector 76 can assume the position at least in the region of the first coupling groove 34 or the second coupling groove 52 only by utilizing the elastic elongation of the connector 76 and / or the elastic deformability of the first component 12 and the second component 14. In this respect, due to the friction forces effective between the first coupling groove 34 and the connector 76 and between the second coupling groove 52 and the connector 76, an independent and undesired backward rotation of the connector 76 is prevented.

[0163] Alternatively, the first coupling groove 34 and / or the second coupling groove 52 can be configured such that the respectively assigned groove bottom 40, 58, which was previously described as a portion of a cylindrical outer peripheral surface characterized by a constant radius, is designed as a cam track. Starting from the shape of the cylindrical outer peripheral surface, this cam track has a continuously increasing radius in the rotation direction of the connector 76. In this configuration, when the connector 76 is rotated by means of the tool 72, the first component 12 and the second component 14 are moved toward each other and are continuously clamped by means of the connector.

[0164] In this variation, an independent and undesired rearward rotation of the connector 76 is also prevented due to the friction forces effective between the first coupling groove 34 and the connector 76 and between the second coupling groove 52 and the connector 76 .

[0165] Figure 6 and Figure 8 A second embodiment of the connector 76 is shown. Figure 1 and Figure 2 In the component connector 10 of FIG. 1 , the connector 76 according to the second embodiment may be used instead of the connector 76 in FIG. 1 . Figure 5 2 and 3. The connector 76 according to the first embodiment is shown in FIG.

[0166] Only the differences with respect to the connector 76 according to the first embodiment will be discussed below. Identical or mutually corresponding elements are denoted by the same reference numerals.

[0167] In the second embodiment, the pusher 86 is in the shape of a complete disk.

[0168] The first engagement element 78 , the second engagement element 80 , the third engagement element 82 and the fourth engagement element 84 are again each designed as an arcuate projection on the pusher 86 .

[0169] However, each of the first engagement element 78, the second engagement element 80, the third engagement element 82 and the fourth engagement element 84 is now designed to have a surface pointing radially inwards as a cam surface, the radial distance of which from the center point of the disk decreases in the direction R. In order to see this construction more clearly, Figure 6 Two auxiliary lines H1, H2, each having a constant radius, are shown in FIG.

[0170] The connector 76 according to the second embodiment is screwed into the first coupling groove 34 and the second coupling groove 52 in the same manner as the connector 76 according to the first embodiment so as to connect the first component 12 and the second component 14. Due to the configuration of the first engaging element 78, the second engaging element 80, the third engaging element 82 and the fourth engaging element 84 having the above-mentioned cam surfaces, the rotation of the connector 76 relative to the coupling grooves 34, 52 causes the first component 12 and the second component 14 to move toward each other and causes the connector 76 to become continuously clamped in the coupling grooves 34, 52.

[0171] It should be understood that Figure 1 and Figure 2 In all variants of the component connection 10 , the positioning elements 32 a , 32 b are optional.

[0172] Fig. 9 A component connection 10 according to a third embodiment is shown.

[0173] Only the differences with respect to the first and second embodiments of the component connection 10 will be described below. For the remainder, reference is made to the above description. Generally, the same reference numerals are used for identical or mutually corresponding elements.

[0174] The first difference between the third embodiment of the component connection 10 and the first and second embodiments is that in the component connection 10 according to the third embodiment, there are no positioning grooves and positioning elements are not used. They are no longer necessary, as will be explained below.

[0175] Another difference relates to the run of the groove bottom 40 , 58 of the first coupling groove 34 or the second coupling groove 52 .

[0176] Compared to the first two embodiments, the groove bottom 40 , 58 in the third embodiment is designed as a plane surface, which extends substantially parallel to the first contact surface 16 or the second contact surface 18 .

[0177] Furthermore, the first undercut 44 and the third undercut 48 are designed as transverse grooves extending along the groove bottom 40. Therefore, in the third embodiment, the transverse grooves forming the undercuts 44, 48 extend in a linear manner. The associated groove depth direction extends parallel to the width direction of the first coupling groove 34.

[0178] The same applies to the second undercut 62 and the fourth undercut 66. In addition, they are designed as transverse grooves extending along the groove bottom 58. Therefore, in the third embodiment, the transverse grooves forming the undercuts 62, 66 extend in a linear manner. The associated groove depth direction extends parallel to the width direction of the second coupling groove 52.

[0179] Another difference is that in the component connection 10 according to the third embodiment, the connector 76 according to the third embodiment is used. Fig.10 , Fig.11 and Fig.12 Shown in detail.

[0180] The connector 76 according to the third embodiment includes a carrier 90 .

[0181] exist Fig.11 and Fig.12 In the variant shown, this is designed in one piece and comprises a first double-T-shaped wall element 92 with a first bearing opening 94 and a second double-T-shaped wall element 96 with a second bearing opening 98 .

[0182] The two wall elements 92 , 96 are arranged opposite to each other at a distance and are each coupled to a connecting portion 100 , 102 at two respective opposite ends.

[0183] When the connector 76 is arranged in the first coupling groove 34 and / or the second coupling groove 52, the two connecting parts 100, 102 are configured to abut against the opposite ends of the first coupling groove 34 and / or the second coupling groove 52. Therefore, the first component 12 and the second component 14 can be brought to a predetermined relative position by means of the carrier 90.

[0184] The carrier 90 thus fulfills the function performed by the positioning element 32 a and / or the positioning element 32 b in the component connection 10 according to the first embodiment and according to the second embodiment.

[0185] In the component connection using two or more connectors 76 according to the third embodiment, it is also feasible to configure at least one of the first coupling groove 34 and the second coupling groove 52 for at least one of the connectors 76 to be larger in its running direction than the corresponding size of the connector 76. Such a first coupling groove 34 or second coupling groove 52 can be used for tolerance compensation.

[0186] The pusher 86 is mounted on the carrier 90 in a rotatable manner about the rotation axis A via a first bearing opening 94 and a second bearing opening 98 .

[0187] Furthermore, the pusher body 86 now comprises a first pusher arm 104 , a second pusher arm 106 and a first holding arm 108 and a second holding arm 110 .

[0188] The first push arm 104 and the second push arm 106 extend in diametrically opposite directions relative to the axis of rotation A.

[0189] The first retaining arm 108 and the second retaining arm 110 also extend in diametrically opposite directions relative to the axis of rotation A.

[0190] Therefore, the first pushing arm 104 , the second pushing arm 106 , the first holding arm 108 , and the second holding arm 110 can also rotate around the rotation axis.

[0191] The functions of the first pushing arm 104, the second loading arm 106, the first holding arm 108, and the second holding arm 110 will be described in detail below.

[0192] The connector 76 according to the third embodiment further includes a total of four engaging elements, namely, a first engaging element 78 , a second engaging element 80 , a third engaging element 82 , and a fourth engaging element 84 .

[0193] Each of the engagement elements 78 , 80 , 82 , 84 is now designed as an independent component. In particular, the engagement elements 78 , 80 , 82 , 84 are therefore designed as a separate component from the pusher body 86 .

[0194] exist Fig.11 and Fig.12 In the variant shown, the engagement elements 78 , 80 , 82 , 84 are also designed as identical parts.

[0195] Each of the engagement elements 78 , 80 , 82 , 84 is mounted on the carrier 90 so as to be displaceable in translation.

[0196] For this purpose, the first engagement element 78 and the third engagement element 82 each have a guide tongue 78 a , 82 a which is displaceably mounted in an assigned guide track 112 formed on the first connecting part 100 .

[0197] When the connector 76 is arranged in the first coupling groove 34 and / or the second coupling groove 52 , the displacement direction corresponds to the groove depth directions 38 , 56 .

[0198] The second engagement element 80 and the fourth engagement element 84 also comprise in each case a guide tongue 80 a , 84 a , which are displaceably mounted in an associated guide track 114 formed on the second connecting part 102 .

[0199] When the connector 76 is arranged in the first coupling groove 34 and / or the second coupling groove 52 , the displacement direction corresponds to the groove depth directions 38 , 56 .

[0200] In the connector 76 according to the third embodiment, a pusher body 86 is kinematically coupled to each engagement element 78 , 80 , 82 , 84 in each case via a primary cam mechanism.

[0201] All primary cam mechanisms are configured to introduce the assigned engagement element 78 , 80 , 82 , 84 into the associated undercut 44 , 48 , 62 , 66 when the connector 76 is positioned in the first and second coupling recesses 34 , 52 .

[0202] In detail, the first engagement element 78 is kinematically coupled to the pushing body 86 , more precisely to the first pushing arm 104 , via a first primary cam mechanism 116 .

[0203] The first main cam mechanism 116 includes a cam surface 116a arranged at a free end of the first push arm 104. The cam surface 116a extends obliquely with respect to the circumferential direction of the first push arm 104 rotatable about the rotation axis A.

[0204] The associated opposing surface 116b is arranged on the first engagement element 78. More precisely, the opposing surface 116b is formed on the inner side of the first engagement element 78.

[0205] Therefore, when the cam surface 116a slides against the opposing surface 116b, the first engagement element 78 is displaced outward relative to the carrier 90. Therefore, the first engagement element 78 is transferred in the thickness direction of the connector 76 to its extended position.

[0206] Analogously to this, the second engagement element 80 is movably coupled to the pusher body 86 , more precisely to the second pusher arm 106 , via a second primary cam mechanism 118 .

[0207] The second main cam mechanism 118 includes a cam surface 118a arranged at a free end of the second push arm 106. The cam surface 118a extends obliquely with respect to the circumferential direction of the second push arm 106 rotatable about the rotation axis A.

[0208] The associated opposing surface 118b is arranged on the second engaging element 80. More precisely, the opposing surface 118b is formed on the inner side of the second engaging element 80.

[0209] Therefore, when the cam surface 118a slides against the opposing surface 118b, the second engagement element 80 is displaced outward relative to the carrier 90. Therefore, the second engagement element 80 is transferred in the thickness direction of the connector 76 to its extended position.

[0210] The third engagement element 82 is therefore kinematically coupled to the pushing body 86 , more precisely to the first pushing arm 104 , via the third primary cam mechanism 120 .

[0211] The third main cam mechanism 120 includes a cam surface 120a arranged at a free end of the first push arm 104. The cam surface 120a extends obliquely with respect to the circumferential direction of the first push arm 104 rotatable about the rotation axis A.

[0212] The associated opposing surface 120b is arranged on the third engaging element 82. More precisely, the opposing surface 120b is formed on the inner side of the third engaging element 82.

[0213] Therefore, when the cam surface 120a slides against the opposing surface 120b, the third engagement element 82 is displaced outward relative to the carrier 90. Therefore, the third engagement element 82 is transferred in the thickness direction of the connector 76 to its extended position.

[0214] In this regard, the cam surface 116 a and the cam surface 120 a are disposed on the head 104 a of the first push arm 104 .

[0215] When viewed radially, the head 104a has a wedge shape that is beveled on both sides. Therefore, by actuating the first push arm 104, the first push arm 104 can be pushed between the first engagement element 78 and the third engagement element 82 like a wedge, so that they are distributed apart from each other by the head 104a, and thus each assumes their extended position in the thickness direction of the connector 76.

[0216] Furthermore, the fourth engagement element 84 is movably coupled to the pusher body 86 , more precisely to the second pusher arm 106 , via a fourth primary cam mechanism 122 .

[0217] The fourth main cam mechanism 122 includes a cam surface 122a arranged at a free end of the second push arm 106. The cam surface 122a extends obliquely with respect to the circumferential direction of the second push arm 106 rotatable about the rotation axis A.

[0218] The associated opposing surface 122b is arranged on the fourth engaging element 84. More precisely, the opposing surface 122b is formed on the inner side of the fourth engaging element 84.

[0219] Therefore, when the cam surface 122a slides against the opposing surface 122b, the fourth engagement element 84 is displaced outward relative to the carrier 90. Therefore, the fourth engagement element 84 is transferred in the thickness direction of the connector 76 to its extended position.

[0220] In this regard, the cam surface 118 a and the cam surface 122 a are disposed on the head 106 a of the second push arm 106 .

[0221] When viewed radially, the head 106a has a wedge shape that is beveled on both sides. Therefore, by actuating the second push arm 106, the second push arm 106 can be pushed between the second engagement element 80 and the fourth engagement element 84 like a wedge, so that they are distributed apart from each other by the head 106a, and thus each assumes their extended position along the thickness direction of the connector 76.

[0222] Furthermore, in the connector 76 according to the third embodiment, a pusher is movably coupled to each engagement element 78 , 80 , 82 , 84 in each case via an auxiliary cam mechanism.

[0223] All auxiliary cam mechanisms are configured to pull the associated engagement elements 78, 80, 82, 84 translationally toward the center point of the connector 76 in the direction specified by the respective guide rails 112, 114. Thus, the auxiliary cam mechanisms transfer the respectively associated engagement elements 78, 80, 82, 84 to their retracted positions in the longitudinal direction of the connector.

[0224] With the connector 76 positioned in the first coupling recess 34 and the second coupling recess 52 and the engaging elements 78, 80, 82, 84 engaged in their respective associated undercuts 44, 48, 62, 66, the first component 12 and the second component 14 can be moved toward each other and / or placed against each other by applying a force with the aid of an auxiliary cam mechanism where appropriate.

[0225] In detail, the first engagement element 78 is movably coupled to the pusher body 86 , more precisely to the first pusher arm 104 , via a first auxiliary cam mechanism 124 .

[0226] The first auxiliary cam mechanism 124 includes a cam surface 124a arranged at the free end of the first push arm 104. The cam surface 124a is formed on the radially inward side of the head 104 and has the shape of a cylindrical outer peripheral surface portion, that is, it is curved with a constant radius. The axis of curvature extends parallel to the rotation axis A.

[0227] The associated opposing surface 124b is arranged on a protrusion on the inner side of the first engagement element 78. The opposing surface 124b faces radially outwards with respect to the axis of rotation A.

[0228] The opposing surface 124b is also curved about an axis of curvature extending parallel to the rotation axis A. However, the radius of curvature is not constant but increases continuously in the actuation direction.

[0229] Thus, when the cam surface 124a slides against the opposing surface 124b, the first engagement element 78 is pulled inwardly relative to the carrier 90 (ie, in the direction of the rotation axis A). Thus, the first engagement element 78 is transferred to a retracted position relative to the longitudinal direction of the connector 76 .

[0230] The second engagement element 80 is movably coupled to the pusher body 86 , more precisely to the second pusher arm 106 , via a second auxiliary cam mechanism 126 .

[0231] The second auxiliary cam mechanism 126 includes a cam surface 126a arranged at the free end of the second push arm 106. The cam surface 126a is formed on the radially inward side of the head 106a and has the shape of a cylindrical outer peripheral surface portion, that is, it is curved with a constant radius. The axis of curvature extends parallel to the rotation axis A.

[0232] The associated opposing surface 126b is arranged on a protrusion on the inner side of the second engagement element 80. The opposing surface 126b faces radially outwards with respect to the axis of rotation A.

[0233] The opposing surface 126 b is also curved about an axis of curvature extending parallel to the rotation axis A. However, the radius of curvature is not constant but increases continuously in the actuation direction.

[0234] Therefore, when the cam surface 126a slides against the opposing surface 126b, the second engagement element 80 is pulled inwardly relative to the carrier 90 (ie, in the direction of the rotation axis A). Therefore, the second engagement element 80 is transferred to the retracted position relative to the longitudinal direction of the connector 76.

[0235] The third engagement element 82 is also movably coupled to the pusher body 86 , more precisely to the first pusher arm 104 , via a third auxiliary cam mechanism 128 .

[0236] The third auxiliary cam mechanism 128 includes a cam surface 128a arranged at the free end of the first push arm 104. The cam surface 128a is formed on the radially inward side of the head 104a and has the shape of a cylindrical outer peripheral surface portion, that is, it is curved with a constant radius. The axis of curvature extends parallel to the rotation axis A.

[0237] The associated opposing surface 128b is arranged on a protrusion on the inner side of the third engagement element 82. The opposing surface 128b faces radially outwards with respect to the axis of rotation A.

[0238] The opposing surface 128 b is also curved about an axis of curvature extending parallel to the axis of rotation A. However, the radius of curvature is not constant but increases continuously in the actuation direction.

[0239] Therefore, when the cam surface 128a slides against the opposing surface 128b, the third engagement element 82 is pulled inwardly relative to the carrier 90 (ie, in the direction of the rotation axis A). Therefore, the third engagement element 82 is transferred to the retracted position relative to the longitudinal direction of the connector 76.

[0240] Furthermore, the fourth engagement element 84 is movably coupled to the pusher body 86 , more precisely to the second pusher arm 106 , via a fourth auxiliary cam mechanism 130 .

[0241] The fourth auxiliary cam mechanism 130 includes a cam surface 130a arranged at the free end of the second push arm 106. The cam surface 130a is formed on the radially inward side of the head 106a and has the shape of a cylindrical outer peripheral surface portion, that is, it is curved with a constant radius. The axis of curvature extends parallel to the rotation axis A.

[0242] The associated opposing surface 130b is arranged on a protrusion on the inner side of the fourth engagement element 84. The opposing surface 130b faces radially outwards with respect to the axis of rotation A.

[0243] The opposing surface 130 b is also curved about an axis of curvature extending parallel to the rotation axis A. However, the radius of curvature is not constant but increases continuously in the actuation direction.

[0244] Therefore, when the cam surface 130a slides against the opposing surface 130b, the fourth engagement element 84 is pulled inwardly relative to the carrier 90 (ie, in the direction of the rotation axis A). Therefore, the fourth engagement element 84 is transferred to the retracted position relative to the longitudinal direction of the connector 76.

[0245] The first retaining arm 108 and the second retaining arm 110 are used to hold the corresponding assigned engaging elements 78, 80, 82, 84 in a specified position when the main cam mechanism 116, 118, 120, 122 and / or the auxiliary cam mechanism 124, 126, 128, 130 have not been operated, for example because the push arms 104, 106 are in a position where they do not contact the engaging elements 78, 80, 82, 84.

[0246] In the third embodiment of the connector 76 shown, a first retaining arm 108 is assigned to the first engagement element 78 and to the third engagement element 82. The first retaining arm 108 has a radially outwardly facing retaining surface 108a.

[0247] Opposite to the retaining surface 108a, the first engaging element 78 has an opposite retaining surface 78b, and the third engaging element 82 has an opposite retaining surface 82b. When the first retaining arm is in the corresponding position, they can abut against the retaining surface 108a, so that the first engaging element 78 and the third engaging element 82 cannot be further displaced in the direction of the rotation axis A.

[0248] The second retaining arm 110 is assigned to the second engagement element 80 and to the fourth engagement element 84. The second retaining arm 110 also has a radially outwardly facing retaining surface 110a.

[0249] Opposite to the retaining surface 110a, the second engaging element 82 has an opposite retaining surface 82b, and the fourth engaging element 84 has an opposite retaining surface 84b. When the second retaining arm 110 is in the corresponding position, they can abut against the retaining surface 110a, so that the second engaging element 80 and the fourth engaging element 84 cannot be further displaced in the direction of the rotation axis A.

[0250] Fig.13 A modification of the connector 76 according to the third embodiment is shown. Fig.11 and Fig.12 The variant in FIG. 1 differs only in that the carrier 90 is composed of two carrier parts 90 a , 90 b .

[0251] Furthermore, the carrier parts 90a, 90b are designed as identical parts.

[0252] otherwise, Fig.13 The connector 76 corresponds to Fig.11 and Fig.12 connector.

[0253] All connectors 76 according to the third embodiment have a length L1 measured in the extension direction. Furthermore, the connectors 76 have a width L2 measured transversely to the insertion direction, and have a thickness L3 also measured transversely to the insertion direction.

[0254] The thickness L3 is always smaller than the width L2. Therefore, the thickness L3 is always the minimum outer dimension of the two-dimensional or flat strip-shaped connector 76.

[0255] In the case of all connectors 76 according to the third embodiment as shown, the ratio of width L2 to length L1 is between 1 and 3. In a preferred variant, this ratio is between 1.4 and 2. The width L2 is therefore precisely greater than or equal to the length L1.

[0256] Fig.14 Shown for production Fig. 9 and Fig.10 The sequence of the component connection 10 according to the third embodiment is shown. The component connection 10 comprises Fig.11 and Fig.12 A connector 76 according to a third embodiment is shown.

[0257] in this regard, Fig.14Three situations are shown which occur successively during the production of a component connection 10. These situations are denoted by a), b) and c). Each situation a), b) and c) is shown by two cross-sectional views. The two cross-sectional views are denoted in each case by (1) and (2), wherein in each case the cross section is defined in the other view, i.e. the cross section (1) is defined in view (2) and vice versa.

[0258] In case a), the connector 76 is inserted into both the first coupling groove 34 and the second coupling groove 52. The pusher 86 is located at a position where the holding surface 108a of the first holding arm 108 abuts against the opposing holding surfaces 78b, 84b of the first and third engaging elements 78,82.

[0259] The retaining surface 110 a of the second retaining arm 110 abuts against the opposing retaining surfaces 80 b , 84 b of the second and fourth engaging elements 80 , 81 .

[0260] The length of the retaining arms 108, 110 and the positions of the relative retaining surfaces 78b, 80b, 82b and 84b on the engaging elements 78, 80, 82, 84 are adapted to the groove depths of the first connecting groove 34 and the second connecting groove 52, so that when the connector 76 abuts against both the groove bottom 40 and the groove bottom 58, a gap of width D is created between the first contact surface 16 and the second contact surface 18.

[0261] The engagement elements 78 , 80 , 82 , 84 do not yet engage in the assigned undercut 44 , 48 , 62 , 66 .

[0262] Furthermore, the connecting portions 100, 102 each abut against one end of the first coupling groove 34 and one end of the second coupling groove 52. Thus, the first component 12 and the second component 14 assume a specified relative position with respect to each other.

[0263] In case b), the pusher 86 is rotated about 15 degrees in the clockwise direction compared to case a). Therefore, the clockwise direction corresponds to the actuation direction of the pusher 86.

[0264] In this respect, for example, a tool (not shown) engaging in the actuating element 88 can be used. Fig.14 ) causes the pusher 86 to rotate.

[0265] In case b), the engagement elements 78 , 80 , 82 , 84 are now unfolded by means of the respectively assigned main cam mechanism 116 , 118 , 120 , 122 , so that they engage in the respectively assigned undercut 44 , 48 , 62 , 66 .

[0266] As far as the auxiliary cam mechanism 124, 126, 128, 130 is concerned, the assigned cam surface 124a, 126a, 128a, 130a already abuts against a portion of the assigned opposite surface 124b, 126b, 128b, 130b located at the front in the actuation direction. However, these portions are constructed so that the auxiliary cam mechanism 124, 126, 128, 130 does not yet cause any movement of the engagement element 78, 80, 82, 84. Such movement will also be blocked by the retaining arms 108, 110, which in case b) still abut against the assigned opposite surface 78b, 80b, 82b, 84b.

[0267] In case c), the pusher 86 is rotated by approximately 90 degrees in the clockwise direction compared to case a).

[0268] The cam surfaces 124a, 126a, 128a, 130a of the auxiliary cam mechanisms 124, 126, 128, 130 interact with parts of the assigned relative surfaces 124b, 126b, 128b, 130b which are positioned further rearward in the actuation direction, so that the coupling elements 78, 80, 82, 84 are in each case pulled translationally in the direction of the rotation axis A by means of the auxiliary cam mechanisms 124, 126, 128, 130.

[0269] This results in the first contact surface 16 and the second contact surface 18 coming into contact with each other. This contact may be effected by a force.

[0270] In the position prevailing in case c), the auxiliary cam mechanisms 124, 126, 128, 130 can also be self-locking. Thus, the first component 12 is fastened to the second component 14 in a reliable manner.

[0271] The above description relates to the component connection 10 designed as a corner connection according to the third embodiment.

[0272] Figures 15 to 19 Other modifications of the connector 76 according to the third embodiment are shown.

[0273] In all Figures 15 to 19 , connector 76 is shown cut along a center plane.

[0274] In addition, in order to improve clarity, the pusher 86 is not Figures 15 to 19 Only parts of the carrier are shown, so that only the cutout parts of the connecting parts 100, 102 can be seen. In particular, the wall elements 92 and 96 cannot be seen.

[0275] Figures 15 to 19The variation relates to the configuration of the relative surfaces of the auxiliary cam mechanism. Based on the cross-sectional view of the connector, an explanation is given based on the relative surface 128b of the third auxiliary cam mechanism 128 and the relative surface 130b of the fourth auxiliary cam mechanism 130. It should be understood that these explanations apply to the remaining auxiliary cam mechanisms 124, 126 in the same manner.

[0276] in this regard, Fig.15 A variation is shown in which the opposing surfaces 128b and 130b are arranged similar to Figures 11 to 14 The view in the view extends in this way.

[0277] Therefore, the opposing surface 128b and the opposing surface 130b have a radius of curvature that increases continuously to a small extent in the actuation direction B. This results in a moderate increase in force when the third and fourth engaging elements 82, 84 are being pulled. Furthermore, the third and fourth engaging elements 82, 84 move uniformly toward each other relative to their displacement paths.

[0278] In contrast, Fig.16 The opposing surfaces 128b and 130b in the illustrated variation each have a portion 128c, 130c that is aligned with the opposing surfaces 128b, 130c. Fig.15 The variant shown is flatter in comparison and is located at the front in the actuation direction B.

[0279] Therefore, when the third auxiliary cam mechanism 128 and the fourth auxiliary cam mechanism 130 are actuated, the force required to move the engagement elements 82, 84 increases very slowly, but eventually is at the same level as Fig.15 The levels of the variants shown are comparable.

[0280] This is associated with a relatively slow movement of the engagement elements 82 , 84 towards each other.

[0281] Fig.17 The variation in shows the opposite scenario.

[0282] In this case, the opposing surface 128b and the opposing surface 130b each have a portion 128d, 130d, which is aligned with the Fig.15 The variant shown is in comparison steeply inclined and is located at the front in the actuation direction B.

[0283] Therefore, when the third and fourth auxiliary cam mechanisms 128 , 130 are actuated, relatively high forces are initially required to move the engagement elements 82 , 84 .

[0284] This is associated with a relatively rapid movement of the engagement elements 82 , 84 towards each other.

[0285] exist Fig.18In the variant shown, the opposing surfaces 128b and 130b each have a retaining portion 128e, 130e. The retaining portion 128e, 130e should be understood as a portion of the opposing surfaces 128b, 130b during their interaction with the assigned cam surfaces 128a, 130a, the engagement elements 82, 84 do not move toward each other or move toward each other only to an insignificant extent.

[0286] Therefore, the third auxiliary cam mechanism 128 and the fourth auxiliary cam mechanism 130 can be actuated in two stages, wherein in the first stage the corresponding cam surface 128a, 130a moves to the assigned retaining portion 128e, 130e and in the second stage moves further from the retaining portion 128e, 130e.

[0287] exist Fig.19 In a variation of the present invention, the opposing surface 128b and the opposing surface 130b each have a locking portion 128f, 130f.

[0288] Each locking portion 128f, 130f comprises a sawtooth profile, a wave profile or a combined sawtooth and wave profile. Therefore, the corresponding assigned cam surface 128a, 130a can be hooked into the locking portion 128f, 130f by engaging in one or more associated spaces between the sawtooth and / or the wave.

[0289] In this way, on the one hand, an operator of the connector 67 can be signaled tactilely and / or acoustically that a desired operating state of the connector 67 has been achieved.

[0290] Furthermore, the locking portions 128f, 130f increase the self-locking of the assigned auxiliary cam mechanisms 128, 130. Thus, such a connector 67 provides a high degree of protection against unintended release.

[0291] It should be understood that the third embodiment described with reference to the connector 76 Figures 15 to 19 The variation can also be transferred to the connector 76 according to the second embodiment (see in particular Figure 6 ).

[0292] Therefore, if Fig.18 and Fig.19 As shown, the radially inward surfaces of the coupling elements 78, 80, 82, 84 may also be provided with retaining portions or locking portions, and the radially inward surfaces of the coupling elements 78, 80, 82, 84 interact with the undercuts 44, 48, 62, 66 of the coupling grooves 34, 52 and are formed into cam surfaces whose radial distances from the center point of the disc decrease along the direction R.

[0293] according to Fig.16 and Fig.17 The variations shown may also provide flat portions and / or steeply inclined portions for the radially inwardly facing surfaces of the engaging elements 78 , 80 , 82 , 84 of the connector 76 according to the second embodiment, so as to provide the desired force and displacement progression when the components 12 , 14 are fastened to each other by means of the connector 76 .

[0294] The third embodiment of the connector 76 has been described with reference to Figures 15 to 19 The variation can also be transferred to the component connection using the connector 76 according to the first embodiment (see Figures 1 to 5 ).

[0295] In this respect, the retaining portion and / or the locking portion may be arranged on at least one surface of one of the undercuts 44 , 48 , 62 , 66 forming the coupling groove 34 , 52 .

[0296] It is also possible to provide flat portions and / or steeply inclined portions on at least one surface forming one of the undercuts 44, 48, 62, 66. Thus, when the components 12 and 14 are fastened to each other by means of the connector 76 according to the first embodiment, a desired force and displacement course can be set.

[0297] However, in Fig. 20 It can be clearly seen in FIG. 7 that the connector 76 according to the third embodiment can also be used in a component connection 10 according to the fourth embodiment, which is configured as a bevel joint.

[0298] Likewise, the connector 76 according to the third embodiment can also be used in the component connection 10 according to the fifth embodiment, which is configured as a central part connection. Fig.21 More precisely, two connectors 76 according to the third embodiment are used in this case.

[0299] Fig. 22 A variation of the component connection according to the third embodiment is shown. In general, the component connection 10 comprises a connector 76 according to the third embodiment.

[0300] exist Fig. 22 In the variant shown, all engagement elements 78 , 80 , 82 , 84 and the pusher body 86 are made of a metallic material.

[0301] The carrier 90 is made of a synthetic material.

[0302] This results in a situation where the force flow between the first component 12 and the second component 14 is realized only via the components composed of metal material. Fig. 22 This is indicated by two arrows F1 , F2 .

[0303] Fig.23 A component connection 10 according to another embodiment is shown.

[0304] Likewise, only the differences with respect to the already described embodiments of the component connection 10 will be described below. Generally, the same reference numerals are used for identical or mutually corresponding elements.

[0305] In particular, Fig.23 In the embodiment shown, with respect to the general configuration of the coupling grooves 34, 52, the first component 12 having the first coupling groove 34 and the second component 14 having the second coupling groove 52 correspond to those already mentioned with reference to FIG. Fig. 9 and Fig.10 Parts 12, 14 of the description. Reference is made to these descriptions.

[0306] However, one difference with respect to the previous embodiment is that in Fig.23 In the component connection member 10 shown, the connector 76 according to the fourth embodiment is used. Fig.24 Shown in detail.

[0307] The connector 76 according to the fourth embodiment comprises a one-piece carrier 90 on which the pusher 86 is rotatably mounted.

[0308] However, as will be explained later, the pusher body 86 is now substantially bolt-shaped.

[0309] Furthermore, the second joining element 80 and the fourth joining element 84 are now each connected to the carrier 90 in an articulated manner.

[0310] In the embodiment shown, the second joining element 80 and the fourth joining element 84 are made in one piece with the carrier 90. The hinged connection is established in each case by a film hinge 132, 134. A translational guidance of the second joining element 80 and the fourth joining element 84 on the carrier is therefore no longer necessary.

[0311] Furthermore, the first engagement element 78 and the third engagement element 82 are now designed as an integral component. However, the first engagement element 78 and the third engagement element 82 can still be moved relative to each other in order to be able to engage in the assigned undercut.

[0312] Furthermore, the connector 76 according to the fourth embodiment comprises a coupling element 136 in the form of a coupling slide 138 .

[0313] The coupling slide 138 comprises a first wedge-shaped portion 140 which is configured to distribute the first engagement element 78 and the third engagement element 82 apart from one another so that these engagement elements 78 , 82 can engage into the assigned undercut.

[0314] Furthermore, the coupling slide 138 has a second wedge-shaped portion 142 arranged thereon, which is configured to distribute the second engagement element 80 and the fourth engagement element 84 apart from one another so that these engagement elements 80 , 84 can engage in the assigned undercut.

[0315] Furthermore, in the connector 76 according to the fourth embodiment, only a single main cam mechanism 116 is provided, which may also be referred to as a first main cam mechanism.

[0316] The coupling element 136 (ie, the coupling slide 138 ) is movably coupled to the pusher body 86 via the main cam mechanism 116 .

[0317] The main cam mechanism 116 includes a cam surface 116a arranged on the outer periphery of the bolt-shaped pusher 86 (see also Fig.25 ).

[0318] The associated opposing surface 116b is formed by the inner periphery of an opening 144 on the coupling element 136 (ie, on the coupling slide 138) (see also Fig.25 ).

[0319] Therefore, when the cam surface 116a slides against the opposing surface 116b, the coupling slide 138 is displaced translationally, so that the first wedge-shaped portion 140 thereof is pulled between the first engagement element 78 and the third engagement element 82, so that they are separated from each other. At the same time, the second wedge-shaped portion 142 is pushed between the second engagement element 80 and the fourth engagement element 84, so that they are separated from each other.

[0320] Fig.25 a) shows the situation during the production of the component connection 10 in which such a distribution results in the engagement elements 78 , 80 , 82 , 84 engaging in the respectively assigned undercut 44 , 48 , 62 , 66 .

[0321] Furthermore, the connector 76 according to the fourth embodiment includes a single auxiliary cam mechanism 124 , which may also be referred to as a first auxiliary cam mechanism.

[0322] The auxiliary cam mechanism 124 includes a cam surface 124a arranged on the outer periphery of the bolt-shaped pusher 86. The cam surface 124a is arranged axially adjacent to the cam surface 116a with respect to the bolt center axis.

[0323] The associated opposing surface 124 b is formed on an integral component including the first engagement element 78 and the third engagement element 82 .

[0324] When the cam surface 124 a slides against the opposing surface 124 b , displacement of the integral component including the first engaging element 78 and the third engaging element 82 in the direction of the pushing body 86 is continuously achieved.

[0325] Fig.25 shows the use for production according to Fig.23 The component connector 10 of the embodiment of the present invention comprises: Fig.23 and Fig.24 A connector 76 according to a fourth embodiment is shown.

[0326] in this regard, Fig.25 Three situations are shown which occur successively during the production of a component connection 10. These situations are denoted by a), b) and c). Each situation a), b) and c) is shown by two cross-sectional views. The two cross-sectional views are denoted in each case by (1) and (2), wherein in each case the cross section is defined in the other view, i.e. the cross section (1) is defined in view (2) and vice versa.

[0327] In case a), the connector 76 is inserted both into the first coupling groove 34 and into the second coupling groove 52. The pusher 86 has been rotated about 65 degrees from the initial position, which is achieved by means of the tool 72 engaging in the actuating element 88 in the present example.

[0328] Thus, in case a), the engagement elements 78 , 80 , 82 , 84 are deployed by means of the main cam mechanism 116 and the coupling slide 138 comprising the first wedge portion 140 and the second wedge portion 142 , so that they engage into the respectively assigned undercut 44 , 48 , 62 , 66 .

[0329] In the case of the auxiliary cam mechanism 124 , the assigned cam surface 124 a and the assigned opposing surface 124 b abut against each other, thereby establishing a specified distance between the carrier 90 and the integral component including the first engagement member 78 and the third engagement member 82 .

[0330] Therefore, there is also a gap having a width D between the first contact surface 16 and the second contact surface 18 .

[0331] In this regard, since the connecting slide 138 distributes the first engaging element 78 and the third engaging element 82 apart from each other by means of the first wedge-shaped portion and thereby also pushes the integral component including the first engaging element 78 and the third engaging element 82 in the direction of the pushing body 86, the cam surface 124a and the relative surface 124b remain in contact with each other.

[0332] In case b), the pusher 86 has been rotated about another 35 degrees compared to case a). First, the main cam mechanism 116 has been used to further move the coupling slide 138. In addition, the auxiliary cam mechanism 124 has achieved a translational movement of the integral component including the first engagement element 78 and the third engagement element 82 relative to the carrier 90, so that the integral component including the first engagement element 78 and the third engagement element 82 can be displaced into the carrier 90, and the first contact surface 16 and the second contact surface 18 can be placed against each other. Therefore, there is no longer a gap between the first contact surface 16 and the second contact surface 18.

[0333] In case c), the pusher 86 has been rotated about another 80 degrees compared to case b). First, the coupling slide 138 has been further displaced using the main cam mechanism 116. In addition, the auxiliary cam mechanism 124 has enabled the integral component including the first engagement element 78 and the third engagement element 82 to continue to move in translation relative to the carrier 90, so that the integral component including the first engagement element 78 and the third engagement element 82 has been displaced to the maximum extent into the carrier 90. Therefore, when a force is applied, the first contact surface 16 and the second contact surface 18 abut against each other.

[0334] In the position prevailing in case c), the primary cam mechanism 116 and the secondary cam mechanism 124 can also be designed to be self-locking. Thus, the first component 12 is fastened to the second component 14 in a reliable manner.

[0335] In order to further facilitate the manipulation of the connector 76 according to the fourth embodiment, a direction indicator 146 may be optionally provided on the pusher 86 and / or on the carrier 90, the direction indicator indicating the rotation direction of the pusher 86 corresponding to the closing direction of the connector 76. Fig.24 In the illustrated embodiment, the direction indicator 146 includes three arrows. It should be understood that only one of these arrows or two of these arrows can form a useful direction indicator 146.

[0336] Furthermore, the connector 76 according to the fourth embodiment may optionally have one or more position indicators 148. The position indicator shows the position of the pusher 86 relative to the other components of the connector 76. Thus, it can be seen whether the connector is in an open position or a closed position. Intermediate positions can also be seen. Fig.24 In the embodiment of the present invention, the position indicator 148 includes three short lines. Two of these lines are positioned on the carrier 90, and one of these lines is arranged on the pusher 86.

[0337] Fig.26 Other modifications of the connector 76 according to the fourth embodiment are shown.

[0338] Fig.26 Only relevant details of the connector 76 are shown. They correspond to Fig.25 Details of a)(1) XXVI.

[0339] To help understand, Fig.26 (a) shows on a larger scale Fig.25 Detail XXVI of a)(1). Therein can be seen the main cam mechanism 116 comprising a cam surface 116a and an opposing surface 116b.

[0340] In this variant, the coupling slide 138 is initially displaced relatively quickly by means of the rotation of the pusher 86. In the region of the end position (see also Fig.25 b) and c)), a relatively high force must be applied in order to be able to further rotate the pusher 86 and thus further displace the coupling slide 138. In this region, a relatively slow displacement of the coupling slide 138 occurs.

[0341] exist Fig.26 In a variation of (b), the cam surface 116a includes a retaining portion 116e.

[0342] Thus, the main cam mechanism 116 can be actuated in two stages, wherein in the first stage the cam surface 116a moves to the assigned retaining portion 116e, ie until the retaining portion 116e abuts against the opposing surface 116b. In the second stage the pusher 86 is further rotated from this position.

[0343] The retaining portion 116e may be configured such that when the retaining portion 116e abuts against the opposing surface 116b, automatic movement of components of the connector 76 is prevented.

[0344] exist Fig.26 In the variation shown in (c), the cam surface 116a includes a locking portion 116f. This is composed of a plurality of planar surface segments. Therefore, there is no radius at the boundary line between the individual surface segments, but there is an edge.

[0345] The rolling of these edges on the relative surface 116b causes a sudden change in the reaction force acting on the actuating tool. In this way, on the one hand, when the desired operating state of the connector 67 is reached, the operator of the connector 67 can be signaled tactilely and / or acoustically.

[0346] Furthermore, the locking portion 116f increases the self-locking of the dispensed main cam mechanism 116. Such a connector 67 thus provides a high degree of protection against unintended release.

[0347] Fig.25(d) shows a variant in which the path along which the coupling slide 138 is displaced and the force required for this purpose have a particularly uniform course. This is achieved because there are no sudden changes in the radius in the effective area of ​​the cam surface 116a, i.e. the radius of the cam surface 116a changes only continuously. The rate of change is relatively low.

[0348] Fig.25 Another variation is shown in (e).

[0349] In this variant, the coupling slide 138 is initially displaced relatively slowly by means of the rotation of the pusher 86. The necessary force also increases relatively slowly. For this purpose, a relatively short section of the cam surface 116 is provided. Thus, the end position is achieved relatively quickly (see also for this purpose Fig.25 b) and c)).

[0350] Fig. 27 and Fig.28 A connector 76 according to a fifth embodiment is shown. Only the differences with respect to the connector 76 already described will be discussed below.

[0351] Again, the connector 76 according to the fifth embodiment comprises a one-piece carrier 90 on which the pusher 86 is rotatably mounted. Likewise, the pusher 86 is substantially bolt-shaped, more precisely cylindrical.

[0352] Furthermore, in the connector 76 according to the fifth embodiment, the first engaging element 78 and the third engaging element 82 are formed by a common component, at least a portion of which is elastically deformable, as will also be described below.

[0353] The second engagement element 80 and the fourth engagement element 84 are formed by a common component, at least a portion of which is also elastically deformable.

[0354] The components forming the first engaging element 78 and the third engaging element 82 and the components forming the second engaging element 80 and the fourth engaging element 84 are separated from each other. In addition, these components are arranged at opposite ends of the carrier 90.

[0355] Furthermore, in the connector 76 according to the fifth embodiment, the engaging elements 78 , 80 , 82 , 84 are movably coupled to the pushing body 86 via the gear mechanism 150 .

[0356] The gear mechanism 150 comprises a drive gear 152 which, in the present example, is formed integrally with the pusher body 86. In this respect, the tooth arrangement of the drive gear 152 extends circumferentially completely around the periphery of the pusher body 86 which is cylindrical in shape.

[0357] The drive gear 152 is designed as a bevel gear.

[0358] Furthermore, the gear mechanism 150 includes a threaded rod assembly 154 .

[0359] The threaded rod assembly 154 includes a threaded rod 156, and a driven gear 158 is arranged on the threaded rod 156. The driven gear 158 is fixedly connected to the threaded rod 156.

[0360] The output gear 158 is also designed as a bevel gear.

[0361] The driving gear 152 and the driven gear 158 mesh with each other. The central axis of the driving gear 152 and the central axis of the driven gear 158 extend perpendicularly to each other.

[0362] The first threaded portion 160 is disposed at a first end of the threaded rod 156 .

[0363] The second threaded portion 162 is disposed at a second end of the threaded rod 156 opposite the first end.

[0364] The first threaded portion 160 is screwed into the threaded hole 164 of the first pressure piece 166 .

[0365] The second threaded portion 162 is screwed into the threaded hole 168 of the second pressure piece 170 .

[0366] The first pressure piece 166 is guided linearly on the carrier 90 and is arranged adjacent to the components which form the first abutment element 78 and the third abutment element 82 .

[0367] The second pressure piece 170 is likewise guided linearly on the carrier 90 and is arranged adjacent to the components which form the second abutment element 80 and the fourth abutment element 84 .

[0368] Therefore, when the pushing body 86 rotates, due to the motion connection with the aid of the gear mechanism 150, the first pressure piece 166 can move toward or away from the components forming the first joining element 78 and the third joining element 82, so that the first joining element 78 and the third joining element 82 protrude relative to the carrier 90 due to elastic deformation, or retract into the interior of the carrier 90 due to elastic deformation.

[0369] In the same manner, the second pressure piece 170 can be moved toward or away from the components forming the second joining element 80 and the fourth joining element 84 so that the second joining element 80 and the fourth joining element 84 protrude relative to the carrier 90 due to elastic deformation or retract into the interior of the carrier 90 due to elastic deformation.

[0370] In this way, the engagement elements 78 , 80 , 82 , 84 can engage into or disengage from the respectively assigned undercut 44 , 48 , 62 , 66 as long as the connector 76 is arranged in the coupling recess 34 , 52 .

[0371] Fig.29 and Fig.30 A variant of the component connection 10 is shown which uses a connector 76 according to a fifth embodiment. The connector 76 and the coupling recesses 34, 52 are shown only in greatly simplified form.

[0372] However, it should be understood that Fig.29 and Fig.30 In the variant shown, the first component 12 and the second component 14 are also fastened to one another, since the engagement elements 78 , 80 , 82 , 84 engage in the respectively assigned undercut 44 , 48 , 62 , 66 .
