Definitions
- Connector for mechanically fastening a first component to a second component and component connection
- the invention relates to a connector for mechanically fastening a first component to a second component.
- the first component has at least one first coupling groove, which has a first undercut acting along a groove depth direction.
- the second component has at least one second coupling groove, which has a second undercut acting along a groove depth direction.
- the invention is further directed to a component connection which comprises a first component with at least one first coupling groove.
- a groove opening of the first coupling groove lies in a contact surface of the first component.
- the first coupling groove has a first undercut acting along a groove depth direction.
- the component connection also includes a second component with at least one second coupling groove.
- a groove opening of the second coupling groove lies in a contact surface of the second component.
- the second coupling groove has a second undercut acting along a groove depth direction.
- the component connection additionally includes a connector of the type mentioned at the beginning.
- a groove depth direction is understood to mean a direction that extends between a groove opening and a groove base.
- a groove opening is usually elongated. Otherwise it is called a hole or a drilling.
- the groove opening is usually opposite the groove base.
- the groove opening is the only opening in the groove.
- only the opening extending along the direction of extension is considered a groove opening.
- AS: GREAT The one open end or the two open ends do not form a groove opening.
- openings made up of other design elements, e.g. B. result in transverse grooves or transverse holes.
- a direction parallel to the longer side of the elongated groove opening is to be regarded as the direction of progression or direction of extension.
- Grooves that have a groove depth that changes along the direction of travel in such a way that the groove depth decreases to zero at one or both ends of the groove are viewed as grooves limited on one or both sides.
- an undercut acting along a groove depth direction has an undercut with respect to a direction from the groove base to the groove opening.
- An element that engages in the undercut cannot therefore be pulled out of the groove along the groove depth direction because it forms a positive connection with the undercut.
- Such undercuts and the associated coupling grooves can be produced with known tools using known methods.
- the tools can be stationary or hand-held.
- Connectors and component connections of the type mentioned at the beginning are generally known. They are used, for example, to mechanically fasten wooden components to one another, i.e. to connect them. Such components can be furniture parts. Alternatively, the components can be structural elements of a wooden structure, e.g. B. from the field of construction. However, it is understood that the connectors and component connections mentioned at the beginning are not limited to a specific material class or a specific area of application. They can also easily be used for components made of plastic, metal, ceramic, stone, etc.
- the undercuts acting along an associated groove depth direction have the advantage that the components can be fastened to one another with high reliability.
- a positive connection can be achieved using the undercuts will be realized. This is particularly true in comparison to coupling grooves that do not have such an undercut.
- the present invention is based on the object of specifying a connector and an associated component connection that are simple and inexpensive with a known high level of connection reliability.
- the task is solved by a connector for mechanically fastening a first component to a second component.
- the first component has at least one first coupling groove, which has a first undercut acting along a groove depth direction.
- the second component has at least one second coupling groove, which has a second undercut acting along a groove depth direction.
- the connector is plate-shaped or flat bar-shaped.
- the connector comprises a first engagement element for anchoring in the first undercut and a second engagement element for anchoring in the second undercut.
- the connector includes a biasing body for positioning at least a portion of the first engagement member in the first undercut and at least a portion of the second engagement member in the second undercut.
- the loading body is kinematically coupled to the first engagement element and the second engagement element.
- the first undercut can be arranged in the area of the groove base of the first coupling groove.
- the second undercut can be arranged in the area of the groove base of the second coupling groove.
- the connector is particularly suitable for connecting components via coupling grooves.
- a thickness direction of the connector which corresponds to the smallest spatial dimension of the connector, extends along a groove width direction, ie perpendicular to a direction of progression of the groove and perpendicular to a groove depth direction. This means that the connector can be easily used in component connections that can only fill a comparatively small installation space. This applies in particular to the use of the connector for connecting plate-shaped components.
- the plate shape or flat bar shape has the advantage that a holding force that acts between the connector and each of the first and second components acts distributed over a comparatively large section of the first component and the second component.
- the holding force is introduced into the respective component via a line contact between the connector and the first and/or second component or via a surface contact between the connector and the first and/or second component. This results in comparatively small mechanical stresses within the first component and the second component.
- a linear or surface-shaped engagement between the connector and the first undercut and/or second undercut can be realized. This leads to a particularly secure and reliable attachment of the first component and the second component to one another.
- the connector has both a first engagement element and a second engagement element and that a single loading body is provided for both engagement elements also contributes to this.
- the loading body can both position the engagement elements into the respectively assigned undercut and also position the engagement elements within the respectively assigned undercut.
- the connector When assembled, the connector is anchored simultaneously in the first component and in the second component.
- the engagement elements can therefore also be referred to as anchoring elements or jaws.
- such a connector is structurally simple, which promotes cost-effective production.
- it is easy to use because such a connector can be used to quickly and easily attach components to one another.
- a kinematic coupling of two elements is to be understood in such a way that these two elements can only be moved independently of one another.
- the movement of the second element can be subject to restrictions that result from the movement of the first element.
- the movement of the two elements can be the same or different.
- the first element and the second element are firmly connected. So they always move together.
- the first element and the second element are movably coupled. This means that the first element and the second element can move relative to each other, but these movements are dependent on each other.
- the application body can be firmly connected to the first engagement element and/or the second engagement element.
- the first engagement element and/or the second engagement element can be movably coupled to the loading body.
- the first engagement element and/or the second engagement element can therefore be moved relative to the loading body, the movement of the first engagement element and/or the second engagement element preferably being dependent on a movement of the loading body.
- plate shape or flat bar shape come into play in particular compared to circular cylindrical or round bar-shaped connectors, since plate-shaped or flat bar-shaped connectors can be coupled to them over comparatively large sections of the components to be connected.
- a given component thickness often means that at least one dimension of the connector cannot be increased arbitrarily. In the case of a circular cylindrical or round rod-shaped connector, this is usually the diameter.
- the associated thickness is limited by the component thickness. The remaining dimensions can essentially be freely adjusted.
- first engagement element and the second engagement element must protrude at least in the assembled state and at least locally from the remaining components of the plate-shaped or flat bar-shaped connector in order to be able to engage in the associated undercut.
- the first is preferred Engaging element and the second engaging element extend parallel to the thickness direction of the connector.
- a connector according to the present invention is always designed as a coherent unit. This applies to the entire usage phase of the connector. This means that once the connector is manufactured, it forms a coherent unit, regardless of whether it is currently being used to mechanically connect components or not. All components and components of the connector are therefore held together in a captively secure manner. This makes handling the connector easier.
- the first engagement element has a first holding surface for contact with the first undercut and the second engagement element has a second holding surface for contact with the second undercut.
- the first holding surface and the second holding surface run parallel.
- the connector is constructed symmetrically. This means that the connector is designed in such a way that either the first engagement element can be anchored in the first undercut and the second engagement element in the second undercut or the first engagement element in the second undercut and the second engagement element in the first undercut.
- the first engagement element and the second engagement element are made of a metal material. This allows the engagement elements to be anchored with particularly high reliability in the associated coupling grooves and in particular the undercuts present there.
- the first engagement element and/or the second engagement element are/is firmly connected to the loading body.
- the first engagement element and/or the second engagement element can be integral with the Actuation body can be made, e.g. B. by means of a casting or injection molding process.
- the first engagement element and/or the second engagement element can be connected to the loading body during the manufacture of the connector, e.g. B. through a suitable joining process. Both variants result in a connector that is structurally particularly simple and therefore particularly cost-effective to produce. Assembly activities for producing the connector are limited to the assembly of the first engagement element and/or the second engagement element or can be eliminated entirely.
- the loading body can have the shape of a circular disk section or the shape of a circular disk.
- the loading body is therefore structurally simple and can be produced with little effort.
- such a shape is favorable when it comes to positioning the first engagement element and/or the second engagement element in the respectively assigned undercut.
- a circular disk section-shaped or circular disk-shaped loading body has comparatively few geometric elements, e.g. B. corners and edges, which, when moving the loading body, collide in an undesirable manner with elements of the first component and / or the second component and can be blocked by them. Rather, such a shape of the loading body promotes that it slides off upon contact with the first component and/or the second component and is thus moved in the direction of the desired position.
- An actuating element of the actuating body i.e. an element via which an actuating force or an actuating torque can be introduced into the actuating body, can in this context be arranged centrally in the circular disk section shape or centrally in the circular disk shape. This leads to an even, ideally symmetrical force progression.
- At least one of the first engagement element and the second engagement element is designed as an arcuate projection.
- Such engagement elements can be positioned particularly easily in assigned undercuts.
- Engagement elements particularly suitable for interacting with arcuate groove sections and arcuate undercuts are particularly suitable for interacting with arcuate groove sections and arcuate undercuts. In such a configuration, the engagement elements can be easily inserted into the respective associated undercut by means of a rotational movement of the connector.
- the connector includes, in addition to the first engagement element and the second engagement element, a third engagement element and a fourth engagement element.
- the third engagement element is preferably designed to be anchored in a third undercut.
- the first coupling groove advantageously has the third undercut, the third undercut acting along a groove depth direction of the first coupling groove.
- the fourth engagement element is preferably designed to be anchored in a fourth undercut.
- the second coupling groove advantageously has the fourth undercut, the fourth undercut acting along a groove depth direction of the second coupling groove.
- the third engagement element can be provided at the same end of the connector as the first engagement element.
- the fourth engagement element can be arranged at the same end of the connector as the second engagement element.
- the third engagement element has a third holding surface for contact with the third undercut and the fourth engagement element has a fourth holding surface for contact with the fourth undercut.
- the third holding surface and the fourth holding surface run parallel.
- Such a connector has a simple structure.
- stable component connections can be created with such a connector.
- the third holding surface and the fourth holding surface preferably also run parallel to the first holding surface and the second holding surface.
- the connector is also constructed symmetrically. This means that the connector is designed in such a way that the third engagement element can optionally be anchored in the third undercut and the fourth engagement element in the fourth undercut or the third engagement element in the fourth undercut and the fourth engagement element in the third undercut.
- the connector which comprises a first engagement element, a second engagement element, a third engagement element and a fourth element, is designed symmetrically in such a way that each of the engagement elements can be anchored in each of the undercuts.
- Such a connector can therefore be used in four different orientations. A user therefore does not need to pay attention to the orientation in which he inserts the connector into the coupling grooves. This makes using the connector easier.
- one or more of the engagement elements has at least one insertion bevel. This makes it easier to introduce the respective engagement element into an associated undercut.
- At least one of the engagement elements is coupled to the loading body via a gear.
- the transmission ensures that the engagement element can be moved in a predetermined manner depending on the loading body. Acting on one of the engagement elements by means of the loading body thus results in a predetermined movement of the engagement element, so that it can engage reliably and in a predetermined manner in an associated undercut.
- the first engagement element and/or the second engagement element can be selectively moved into a retracted position or an extended position, for example along a thickness direction of the connector. This happens with high reliability and precision.
- the retracted position can be particularly suitable for easily inserting 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 designed to do the first To anchor the engagement element and/or the second engagement element in the respectively assigned undercut.
- first engagement element and/or the second engagement element can be selectively moved into a retracted position or an extended position, for example along a longitudinal direction of the connector which runs transversely to the thickness direction of the connector and which, in the assembled state, runs along a groove depth direction.
- the extended position can be particularly suitable for easily inserting 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 coordinated with the groove depths of the first coupling groove and the second coupling groove in such a way that the first component and the second component are kept at a defined distance from one another when the connector is inserted into both the first coupling groove and the second coupling groove and assumes the extended position.
- This distance corresponds to an approach path, i.e. a distance over which the first component and the second component are moved towards one another when the connector is moved into the retracted position until they rest against one another via the respective contact surfaces.
- the retracted position can be designed to place first and second components to be fastened together by means of the connector against one another. Such a system can be implemented under the application of force.
- the loading body is kinematically coupled via a gear transmission to at least one of the first engagement element and the second engagement element.
- a gear transmission is understood to mean a transmission that includes at least one toothed section that serves for kinematic coupling.
- the toothed section does not necessarily have to be on a circumference of a wheel-shaped element revolve completely.
- the toothed section can also be designed as a toothed rack or as an arcuate toothed segment.
- One or more gear transmissions can be provided.
- Gear drives are simple and robust in construction. Furthermore, they can transmit comparatively high forces and moments with a compact structure. At least one extended position and at least one retracted position can therefore be easily achieved by means of the gear transmission.
- the loading body is kinematically coupled to at least one of the first engagement element and the second engagement element via a primary cam mechanism.
- the designation of the cam gear serves primarily as a simple explanation. A number of cam gears are not implied. Cam gears are simple and robust in construction. In addition, a non-uniform translation between the loading body and the engagement element can be achieved in this way. At least one extended position and at least one retracted position can be easily achieved by means of the primary cam mechanism.
- the primary cam mechanism can have a cam surface which is arranged on the loading body. Furthermore, the primary cam mechanism can have a counter surface assigned to the cam surface, which is arranged on at least one of the first engagement element and the second engagement element or is operatively connected to at least one of the first engagement element and the second engagement element.
- the counter surface is therefore provided directly on the associated engagement element or on an intermediate element lying kinematically between the loading body and the associated engagement element.
- a mating surface is associated with the cam surface when it is intended to contact the cam surface to form the primary cam mechanism.
- the curved surface and the counter surface can be of any shape, e.g. B. curved to have an arbitrary but predetermined translation between one To cause movement of the loading body and a movement of the associated engagement element.
- the primary cam gear prefferably has a cam surface which is arranged on the loading body, and has a counter surface assigned to the cam surface, which is arranged on a coupling element which kinematically couples the loading body with at least one of the first engagement element and the second engagement element.
- a coupling element for example, a distance between the loading body and the associated engagement element can be bridged.
- the coupling element can serve to arrange the curved surface and the counter surface in a space-saving manner.
- the coupling element is a coupling slide.
- the cam surface of the primary cam mechanism and the associated counter surface can be self-locking at least in a predetermined relative position. In this way, the associated engagement element can be held in a predetermined relative position relative to the loading body by means of the primary cam mechanism.
- the loading body is kinematically coupled to at least one of the first engagement element and the second engagement element via a secondary cam mechanism.
- the designation of the cam gear as secondary only serves for simple explanation. A number of cam gears is not implied, although in a case where the connector includes a primary cam gear and a secondary cam gear, at least two cam gears are of course present. Cam gears are simple and robust in construction. In addition, a non-uniform translation between the loading body and the engagement element can be achieved in this way. At least one extended position and at least one retracted position can be easily achieved by means of the secondary cam mechanism.
- the secondary cam mechanism can have a cam surface which is arranged on the loading body.
- the secondary cam mechanism can have a counter surface assigned to the cam surface, which is arranged on at least one of the first engagement element and the second engagement element or is operatively connected to at least one of the first engagement element and the second engagement element.
- the counter surface is therefore provided directly on the associated engagement element or on an intermediate element lying kinematically between the loading body and the associated engagement element.
- a mating surface is associated with the cam surface when it is intended to contact the cam surface to form the secondary cam mechanism.
- the curved surface and the counter surface can be of any shape, e.g. B. curved in order to effect an arbitrary but predetermined translation between a movement of the loading body and a movement of the associated engagement element.
- the cam surface of the secondary cam mechanism and the associated counter surface can be self-locking at least in a predetermined relative position. In this way, the associated engagement element can be held in a predetermined relative position relative to the loading body by means of the secondary cam mechanism.
- the primary cam mechanism and the secondary cam mechanism are coordinated with one another in such a way that when the first component and the second component are mounted to one another, the first engagement element and the second engagement element are first transferred into the extended position along a thickness direction of the connector. The first engagement element and the second engagement element are thus anchored in the respectively assigned undercut. Thereafter, the first engagement element and the second engagement element are moved into the retracted position along a longitudinal direction of the connector that runs transversely to the thickness direction of the connector and, in the assembled state, runs along a groove depth direction. The first component and the second component are thus placed against one another.
- the cam surfaces and counter surfaces forming the primary cam mechanism must first interact with one another. Only then are the cam surfaces and counter surfaces forming the secondary cam mechanism allowed to interact with one another.
- the connector comprises a carrier, with the loading body being mounted on the carrier so that it can rotate about an axis of rotation.
- the loading body can be held by the carrier in a defined position relative to the associated engagement elements.
- the carrier can serve to position the connector within the first and/or the second coupling groove.
- the first component and the second component can be positioned relative to one another by means of the carrier. Forces can also be introduced into the connector or directed out of the connector over a comparatively large area by means of the carrier.
- the connector can thus connect the first component and the second component via a high holding force, which, however, only results in comparatively low mechanical stresses within the first component and the second component.
- the carrier is designed with two shells, so that the loading body can be at least partially accommodated between the two shells of the carrier.
- At least one of the first engagement element and the second engagement element can be mounted on the carrier in a translationally displaceable manner.
- Such translational displaceability can be used to bring the engagement element into engagement with an undercut.
- the translational displaceability can be used to move the first component and the second component towards each other. Consequently, the first component and the second component can be reliably applied to each other.
- first engagement element and the second engagement element are connected to the carrier in an articulated manner.
- the joint is formed, for example, by a film hinge. The engagement element is thus held captively on the carrier and is still movable.
- the application body comprises at least one application arm which is rotatable about the axis of rotation.
- an associated engagement element can be precisely and reliably applied with an actuation force.
- the loading arm can form a lever element, by means of which comparatively small forces can be converted into comparatively large forces.
- the application arm can be made of a metal material. Such an application arm is suitable for particularly high forces and is particularly durable.
- At least one curved surface can be arranged at a free end of the loading arm.
- the free end is to be understood as meaning an end facing away from the pivot point of the loading arm. Consequently, the cam mechanism assigned to the cam surface is actuated by a movement of the loading arm.
- the loading body is at least partially bolt-shaped.
- Such an impact body is particularly compact.
- a central axis of the bolt coincides with an axis of rotation of the loading body.
- At least one curved surface can be arranged on an outer circumference of a bolt-shaped section of the loading body. The cam mechanism assigned to the cam surface is therefore actuated by a movement of the loading body.
- the application body has an actuation element for introducing an actuation force and/or an actuation torque.
- the actuating force and/or the actuating torque can thus be introduced into the loading body easily and reliably.
- the actuating element is designed as an engagement opening.
- the engagement opening can be coordinated with an actuation tool that can engage in the engagement opening to operate the loading body.
- the engagement opening has a hexagonal cross-section that is designed to receive one end of an Allen key.
- the engagement opening can be designed as a through opening or bag opening.
- a rotation of the actuating tool of less than 180 degrees, in particular of less than 170 degrees and further in particular of less than 160 degrees is preferably necessary.
- the connector can therefore be easily operated using the operating tool. Relocating the tool is rarely or not necessary at all.
- the object is further achieved by a connector which has a length measured along an 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.
- a ratio of the width to the length is 1 to 3, preferably 1.4 to 2.
- the connector can be designed according to one or more of the aforementioned examples and embodiments, but does not have to be.
- the length, width and thickness can be determined by defining the smallest external dimension as the thickness. The external dimension that is oriented in the insertion direction is then defined as the length and the remaining external dimension as the width.
- the insertion direction is the direction along which the connector is inserted Coupling groove or coupling grooves are inserted to connect assigned components.
- Such connectors are comparatively short in the length direction. This means they can be used to connect components that only have comparatively little space in the lengthwise direction. This is particularly the case with flat components or with corner connections.
- the task is further solved by a component connection.
- the component connection comprises a first component with at least one first coupling groove, the groove opening of which lies in a first contact surface of the first component and which has a first undercut acting along a groove depth direction.
- the component connection also comprises a second component with at least one second coupling groove, the groove opening of which lies in a second contact surface of the second component and which has a second undercut acting along a groove depth direction.
- the component connection also includes a connector according to the invention.
- the connector is arranged in sections within the first coupling groove and in sections within the second coupling groove.
- the first engagement element of the connector engages in the first undercut.
- the second engagement element of the connector engages in the second undercut.
- first contact surface of the first component and the second contact surface of the second component contact each other.
- the result of this is that the part of the connector received 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 area of the groove base of the associated groove. The first component and the second component are therefore attached to one another extremely reliably. Furthermore, such a component connection saves space due to the fact that the connector is plate-shaped or flat rod-shaped.
- At least one of the first coupling groove and the second coupling groove can be larger along its direction of extension than a dimension of the section of the connector accommodated in the first coupling groove or the second coupling groove along the direction of extension of the respectively assigned coupling groove.
- the respective section of the connector can therefore be extended along the direction by a certain distance within the assigned Coupling groove can be moved.
- first and second components can be precisely connected to one another in this way, although at least one of the first coupling groove and the second coupling groove is subject to a positional deviation or a positioning error.
- the contact between the first component and the second component can basically be designed in any way.
- the system is designed as a corner joint, butt joint or miter joint.
- the plate shape or flat bar shape of the connector comes into play, as this shape means it can also be used in miter joints.
- An access channel for a tool can be provided on the first component and/or on the second component, the access channel extending from an outer surface of the workpiece into the first coupling groove and/or into the second coupling groove.
- the loading body in particular an actuating element of the loading body, can be reliably reached via such an access channel. This allows the connector to be operated reliably.
- the access channel is open in the direction of the assigned contact surface.
- Such an access channel can also be referred to as a groove.
- This runs transversely to the assigned coupling groove.
- no drilling template is necessary, since this groove can be produced starting from the contact surface.
- the transverse groove can therefore be easily created using a router or dowel cutter.
- the transverse groove as well as the first coupling groove and the second coupling groove can also be produced using an industrial CNC milling machine.
- the actuating element of the connector is preferably positioned at an end of the access channel on the coupling groove side. The actuating element can therefore be easily accessed with an associated tool.

Rather, the groove depth is zero at a first end 42a of the first coupling groove 34 along the direction of progression, then increases continuously along the direction of progression to a deepest point and then decreases continuously again, so that at a second end 42b of the first coupling groove 34, that along the direction of progression is opposite to the first end, the groove depth is zero again.
- a central axis M of the circular cylinder surface forming the groove base 40 lies outside the first component 12.
- the first coupling groove 34 also has a first undercut 44, which acts along the groove depth direction 38 and is arranged in the area of the groove base 40.

- the second component 14 has a second coupling groove 52, the groove opening 54 of which lies in the second contact surface 18 (see also Figures 3 and 4).
- the groove opening 54 of the second coupling groove is arranged so that it lies opposite the groove opening 36 of the first coupling groove 34 in a state in which the first component 12 and the second component 14 are fastened to one another.
- a groove depth direction 56 of the second coupling groove 52 runs perpendicular to the second contact surface 18.
- a groove base 58 of the second coupling groove 52 is designed as a section of a circular cylinder surface.
- a groove depth of the second coupling groove 52 is therefore not constant. Rather, the groove depth is zero at a first end 60a of the second coupling groove 52 along the direction of progression, then increases continuously along the direction of progression to a deepest point and then decreases continuously again, so that at a second end 60b of the second coupling groove 52, along the direction of progression is opposite to the first end 60a, the groove depth is again zero.
- a central axis M of the circular cylinder surface forming the groove base 58 lies within the second component 14, with the groove base 58 ending perpendicular to the contact surface 18.

- the fourth undercut 66 is designed as a transverse groove running along the groove base 58, with a groove depth direction 68 of the transverse groove being parallel to the central axis M.
- an access channel 70 for a tool 72 is provided on the second component 14.
- the tool 72 is designed as a so-called Allen key, which is only to be understood as an example.
- the access channel 70 extends from an outer workpiece surface 74, which in the example shown adjoins the second contact surface 18 perpendicularly, into the second coupling groove 52. In other words, the access channel 70 penetrates a side wall of the second coupling groove 52. The tool 72 can thus reach a connector to be explained later via the access channel 70, which is arranged in the second coupling groove 52.
- the access channel 70 is open in the direction of the second contact surface 18.
- the access channel 70 can thus be viewed as a groove running transversely to the second coupling groove 52, with a direction of extension of the groove forming the access channel being arranged perpendicular to the direction of extension of the second coupling groove 52 and a groove opening of the groove forming the access channel 70 lying within the second contact surface 18.

- An actuating element 88 is provided on the loading body 86.
- the actuating element 88 is designed as a through opening with a hexagonal cross section. This cross section is dimensioned such that it can cooperate with the tool 72.
- the actuating element 88 is arranged centrally in the loading body 86 if one mentally expands its circular disk section shape into a complete circular disk. In other words, a central axis of the conceptually expanded loading body 86 and a central axis of the actuating element 88 coincide.
- the first engagement element 78, the second engagement element 80, the third engagement element 82 and the fourth engagement element 84 are kinematically coupled to the loading body 86 in that the first engagement element 78, the second engagement element 80, the third engagement element 82 and the fourth engagement element 84 are fixedly connected to the Actuation body 86 are connected.

- the first engagement element 78 and the second engagement element 80 protrude from the same side of the circular disk section-shaped loading body 86. In Figure 5, this side of the loading body 86 points forward. With respect to the central axis of the actuating element 88, the first engagement element 78 and the second engagement element 80 are arranged diametrically opposite one another.
- the third engagement element 82 and the fourth engagement element 84 also protrude from the same side of the circular disk section-shaped loading body 86. However, this side is opposite to the side from which the first engaging member 78 and the second engaging member 80 protrude.
- the third engagement element 82 and the fourth engagement element 84 are also arranged diametrically opposite one another.
- the first engagement element 78 and the third engagement element 82 are also arranged next to one another along a direction that is perpendicular to the circular disk section-shaped application body 86, i.e. runs 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.
- the first component 12 and the second component 14 are fastened to one another by means of the connector 76.
- the connector is first inserted into the second coupling groove 52 as shown in FIG.
- the actuating element 88 is positioned at an end of the access channel 70 on the coupling groove side.
- first engagement element 78 and the second engagement element 80 engage in the second undercut 62.
- the first engagement element 78 and the second engagement element 80 are dimensioned so that they can be received in the groove forming the second undercut 62.

- the tool 72 is brought into engagement with the actuating element 88 via the access channel 70 and the connector 76 is rotated by essentially 90 degrees using the tool 72. In the embodiment shown, this is done in a clockwise direction.
- first engagement element 78 moves into the first undercut 44 and the third engagement element 82 moves into the third undercut 48.
- the second engagement element 80 moves within the second undercut 62 in the direction of the lowest point of the second coupling groove 52.
- the fourth engagement element 84 also moves within the fourth undercut 66 in the direction of the lowest point of the second coupling groove 52.
- the loading body 86 is used to position the first engagement element 78 in the first undercut 44, the second engagement element 80 in the second undercut 62, the third Engagement element 82 in the third undercut 48 and the fourth engagement element 84 in the fourth undercut 66 used.
- the first component 12 and the second component 14 are thus connected by means of the connector 76.
- the connector 76 is arranged in sections within the first coupling groove 34 and in sections within the second coupling groove 52. At the same time, the connector 76 is completely accommodated within the first coupling groove 34 and the second coupling groove 52.
- the dimensions of the first coupling groove 34, the second coupling groove 52 and the connector 76 can be coordinated with one another in such a way that the connector 76 only utilizes an elastic stretchability of the connector 76 and/or an elastic deformability of the first component 12 and the second Component 14 can assume the position described at least in the area of the first coupling groove 34 or the second coupling groove 52.
- An independent and undesirable turning back of the connector 76 is excluded in this context due to the frictional forces acting between the first coupling groove 34 and the connector 76 and between the second coupling groove 52 and the connector 76.
- first coupling groove 34 and/or the second coupling groove 52 can be designed in such a way that the respective associated groove base 40, 58, which has previously been described as a section of a circular cylindrical surface characterized by a constant radius, is designed as a curved path. Starting from the shape of a circular cylindrical surface, this curved path has a constantly increasing radius along a direction of rotation in which the connector 76 is rotated. In this configuration, when the connector 76 is rotated using the tool 72, the first component 12 and the second component 14 are moved towards each other and successively clamped using the connector.
- FIGS. 6 to 8 A second embodiment of the connector 76 is shown in FIGS. 6 to 8.
- the connector 76 according to the second embodiment can be used in the component connection 10 according to FIGS. 1 and 2 instead of the connector 76 according to the first embodiment, which is shown in FIG.
- the loading body 86 has the shape of a complete circular disk.
- 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 loading body 86.

- two auxiliary lines H1, H2, each with a constant radius are shown in FIG.
- 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 way as the connector 76 according to the first embodiment for connecting the first component 12 and the second component 14. Due to the design of the first engagement member 78, the second engagement member 80, the third engagement member 82 and the fourth engagement member 84 with the cam surface described above, rotating the connector 76 relative to the coupling grooves 34, 52 causes the first component 12 and the second Component 14 can be moved towards each other and the connector 76 is successively clamped in the coupling grooves 34, 52. It goes without saying that in all variants of the component connections 10 from Figures 1 and 2, the positioning elements 32a, 32b are optional.
- Figure 9 shows a component connection 10 according to a third embodiment.
- a first difference between the third embodiment of the component connection 10 and the first embodiment and the second embodiment is that in the component connection 10 according to the third embodiment there are no positioning grooves and no positioning elements are used. These are no longer necessary, as will be explained later.
- the groove bases 40, 58 in the third embodiment are designed as flat surfaces that extend essentially parallel to the first contact surface 16 or to the second contact surface 18.

- the two wall elements 92, 96 are arranged opposite one another at a certain distance and are each coupled to a connecting section 100, 102 at two opposite ends.
- the two connecting sections 100, 102 are designed to abut at opposite ends of the first coupling groove 34 and/or the second coupling groove 52 when the connector 76 is arranged within the first coupling groove 34 and/or within the second coupling groove 52.

- the head 104a When viewed radially, the head 104a has the shape of a wedge that is beveled on both sides. By actuating the first actuation arm 104, it can be pushed like a wedge between the first engagement element 78 and the third engagement element 82, so that they are spread apart by means of the head 104a and thus assume their extended position along the thickness direction of the connector 76.

- the head 106a When viewed radially, the head 106a has the shape of a wedge that is beveled on both sides. By actuating the second loading arm 106, it can be pushed like a wedge between the second engagement element 80 and the fourth engagement element 84, so that they are spread apart by means of the head 106a and thus assume their extended position along the thickness direction of the connector 76.

- the counter surface 124b is also curved about an axis of curvature that runs parallel to the axis of rotation A. However, the radius of curvature is not constant, but increases continuously along an actuation direction.
- the first engagement element 78 is thus pulled inwardly with respect to the carrier 90, ie in the direction of the axis of rotation A.
- the first engagement element 78 is thus moved into the retracted position with respect to the longitudinal direction of the connector 76.
- the second engagement element 80 is kinematically coupled to the loading body 86, more precisely the second loading arm 106, via a second secondary cam mechanism 126.

- the curved surface 128a is formed on a radially inwardly facing side of the head 104a and has the Shape of a circular cylindrical surface section, is therefore curved with a constant radius.
- An axis of curvature runs parallel to the axis of rotation A
- An associated mating surface 128b is arranged on a projection on an inside of the third engagement element 82.
- the counter surface 128b points radially outwards with respect to the axis of rotation A.
- the counter surface 128b is also curved about an axis of curvature that runs parallel to the axis of rotation A. However, the radius of curvature is not constant, but increases continuously along an actuation direction.
- the third engagement element 82 is thus pulled inwardly with respect to the carrier 90, i.e. in the direction of the axis of rotation A.
- the third engagement element 82 is thus moved into the retracted position with respect to the longitudinal direction of the connector 76.
- the fourth engagement element 84 is kinematically coupled to the loading body 86, more precisely the second loading arm 106, via a fourth secondary cam mechanism 130.
- the fourth secondary cam mechanism 130 includes a cam surface 130a, which is arranged at a free end of the second loading arm 106.
- the curved surface 130a is formed on a radially inwardly facing side of the head 106a and has the shape of a circular cylindrical surface section, i.e. is curved with a constant radius.
- An axis of curvature runs parallel to the axis of rotation A.
- An associated mating surface 130b is arranged on a projection on an inside of the fourth engagement element 84.
- the counter surface 130b points radially outwards with respect to the axis of rotation A.
- the counter surface 130b is also curved about an axis of curvature that runs parallel to the axis of rotation A. However, the radius of curvature is not constant, but increases continuously along an actuation direction.
- the fourth engagement element 84 is pulled inwardly with respect to the carrier 90, i.e. in the direction of the axis of rotation A.
- the fourth engagement element 84 is thus moved into the retracted position with respect to the longitudinal direction of the connector 76.
- the first holding arm 108 and the second holding arm 110 serve to hold the respectively assigned engagement elements 78, 80, 82, 84 in a predetermined position when the primary cam gears 116, 118, 120, 122 and/or the secondary cam gears 124, 126 ,128, 130 are not yet effective, e.g. B. because the loading arms 104, 106 are in a position in which they do not contact the engagement elements 78, 80, 82, 84.
- the first holding arm 108 is assigned to the first engagement element 78 and the third engagement element 82.
- the first holding arm 108 has a holding surface 108a pointing radially outwards.
- the first engagement element 78 has a counter-holding surface 78b and the third engagement element 82 has a counter-holding surface 82b. If the first holding arm is in the appropriate position, these can rest against the holding surface 108a, so that the first engagement element 78 and the third engagement element 82 cannot be moved further in the direction of the rotation axis A.
- the second holding arm 110 is assigned to the second engagement element 80 and the fourth engagement element 84.
- the second holding arm 110 also has a holding surface 110a pointing radially outwards.
- the second engagement element 82 has a counter-holding surface 82b and the fourth engagement element 84 has a counter-holding surface 84b. This can rest against the holding surface 110a if the second holding arm 110 is in the appropriate position, so that the second engagement element 80 and the fourth engagement element 84 cannot be moved further in the direction of the rotation axis A.
- Figure 13 shows a variant of the connector 76 according to the third embodiment, which only differs from the variant from Figures 11 and 12 in that the carrier 90 is constructed from two carrier components 90a, 90b.
- the carrier components 90a, 90b are also designed as identical parts.
- All connectors 76 according to the third embodiment have a length LI measured along an insertion direction.
- the connectors 76 have a width L2 measured transversely to the insertion direction and a thickness L3 also measured transversely to the insertion direction.
- the thickness L3 is always smaller than the width L2.
- the thickness L3 is therefore always the smallest external dimension of the connector 76, which is plate-shaped or flat bar-shaped.
- a ratio of the width L2 to the length LI is 1 to 3. In preferred variants, this ratio is 1.4 to 2.
- the width L2 is therefore exactly as large as the length LI or larger.
- Figure 14 shows a process for producing the component connection 10 according to the third embodiment, as shown in Figures 9 and 10.
- the component connection 10 includes the connector 76 according to the third embodiment, as shown in FIGS. 11 and 12.
- FIG. 14 In this context, three situations are shown in FIG. 14, which follow one another when producing the component connection 10. These situations are labeled a), b) and c). Each situation a), b), c) is illustrated using two sectional views. This are labeled (1) and (2) in each situation, whereby the cut is defined in the other figure, ie cut (1) is defined in representation (2) and vice versa.
- the connector 76 is inserted into both the first coupling groove 34 and the second coupling groove 52.
- the loading body 86 is in a position in which the holding surface 108a of the first holding arm 108 rests on the counter-holding surfaces 78b, 82b of the first engagement element 78 and the third engagement element 82.
- the holding surface 110a of the second holding arm 110 rests on the counter-holding surfaces 80b, 84b of the second engagement element 80 and the fourth engagement element 84.
- the length of the holding arms 108, 110 and the positions of the counter-holding surfaces 78b, 80b, 82b, 84b on the engagement elements 78, 80, 82, 84 are matched to the groove depths of the first coupling groove 34 and the second coupling groove 52 in such a way that there is a gap the width D between the first contact surface 16 and the second contact surface 18 results when the connector 76 rests on both the groove base 40 and the groove base 58.
- the engagement elements 78, 80, 82, 84 do not yet engage in the associated undercuts 44, 48, 62, 66.
- connecting sections 100, 102 each rest on both one end of the first coupling groove 34 and one end of the second coupling groove 52.
- the first component 12 and the second component 14 thus assume a predetermined relative position to one another.
- the loading body 86 is rotated clockwise by approximately 15 degrees compared to situation a).
- the clockwise direction therefore corresponds to the direction of actuation of the loading body 86.
- the loading body 86 can be rotated, for example, by means of a tool, not shown in FIG. 14, which engages in the actuating element 88.
- the engagement elements 78, 80, 82, 84 are now spread by means of the respectively assigned primary cam gear 116, 118, 120, 122, so that they engage in the respectively assigned undercuts 44, 48, 62, 66.
- the associated cam surfaces 124a, 126a, 128a, 130a are already in contact with a section of the associated counter surfaces 124b, 126b, 128b, 130b that lies at the front along the actuation direction.
- these sections are configured in such a way that the secondary cam gears 124, 126, 128, 130 do not yet cause any movement of the engagement elements 78, 80, 82, 84. Such a movement would also be blocked by the holding arms 108, 110, which in situation b) still rest on the assigned counter-holding surfaces 78b, 80b, 82b, 84b.
- the cam surfaces 124a, 126a, 128a, 130a of the secondary cam gears 124, 126, 128, 130 interact with the sections of the associated counter surfaces 124b, 126b, 128b, 130b that are further back in the actuation direction in such a way that the engagement elements 78, 80, 82, 84 are each pulled translationally in the direction of rotation axis A by means of the secondary cam gears 124, 126, 128, 130.
- the secondary cam gears 124, 126, 128, 130 can also be designed to be self-locking.
- the first component 12 is thus reliably attached to the second component 14.
- Figures 15 to 19 show further variants of the connector 76 according to the third embodiment.
- the connector 76 is shown cut along a central plane in all of FIGS. 15 to 19.
- the loading body 86 is not shown.
- the carrier is only shown in sections, so that only cut parts of the connecting sections 100, 102 can be seen.
- the wall elements 92, 96 cannot be seen.
- Figures 15 to 19 relate to the design of the mating surfaces of the secondary cam gears. Due to the sectional representation of the connector, the explanations are based on the counter surface 128b of the third secondary cam mechanism 128 and the counter surface 130b of the fourth secondary cam mechanism 130. It is understood that the explanations apply in the same way to the remaining secondary cam mechanisms 124, 126.
- FIG. 15 shows a variant in which the counter surface 128b and the counter surface 130b run analogously to the illustrations in FIGS. 11 to 14.
- the counter surface 128b and the counter surface 130b therefore have a radius of curvature that continuously increases to a small extent along the actuation direction B. This results in a moderate increase in force when the third engagement element 82 and the fourth engagement element 84 are pulled in. Furthermore, the third engagement element 82 and the fourth engagement element 84 are moved towards one another evenly with regard to their displacement path.
- the counter surface 128b and the counter surface 130b in the variant according to FIG. 16 each have a section 128c, 130c which is flattened compared to the variant from FIG. 15 and which lies at the front along the actuation direction B.
- a force necessary for moving the engagement elements 82, 84 increases very slowly, but ends at a level that is comparable to that from the variant according to FIG.
- the counter surface 128b and the counter surface 130b each have a section 128d, 130d which is steeper than the variant from FIG. 15 and which lies at the front along the actuation direction B.
- the counter surface 128b and the counter surface 130b each have a holding section 128e, 130e.
- a holding section 128e, 130e is to be understood as meaning a section of the counter surfaces 128b, 130b, upon whose interaction with the associated curved surface 128a, 130a, the engagement elements 82, 84 are not moved towards one another or only to an insignificant extent.
- the third secondary cam gear 128 and the fourth secondary cam gear 130 can therefore be operated in two stages, with the respective cam surface 128a, 130a being moved in a first stage up to the associated holding section 128e, 130e and in a second stage moving further from the holding section 128e, 13 Oe becomes.
- the counter surface 128b and the counter surface 130b each have a latching section 128f, 13 Of.
- Each of the locking sections 128f, 130f comprises a serration profile, a wave profile or a combined serration and wave profile.
- the respectively assigned curve surface 128a, 130a can thus get caught in the locking sections 128f, 130f by engaging in one or more associated spaces between serrations and/or waves.
- an operator of the connector 67 can be haptically and/or acoustically signaled that a desired operating state of the connector 67 has been reached.
- the radially inward-pointing surfaces of the engagement elements 78, 80, 82, 84 which interact with the undercuts 44, 48, 62, 66 of the coupling grooves 34, 52 and are designed as curved surfaces, can therefore have their radial distance from the center of the circular disk reduced along the direction R, can also be provided with holding sections or locking sections, as shown in Figures 18 and 19.
- a holding section and/or a locking section can be provided on at least one surface forming one of the undercuts 44, 48, 62, 66 of the coupling grooves 34, 52.
- a desired force and path curve can thus be set when the components 12, 14 are fastened to one another using the connector 76 according to the first embodiment.
- the connector 76 according to the third embodiment can also be used in a component connection 10 according to a fourth embodiment, which is designed as a miter connection.
- the connector 76 according to the third embodiment can be used in a component connection 10 according to a fifth embodiment, which is designed as a middle part connection. This is shown in Figure 21. More precisely, two connectors 76 according to the third embodiment are used here.
- Figure 22 shows a variant of the component connection according to the third embodiment.
- the component connection 10 includes the connector 76 according to the third embodiment.
- all engagement elements 78, 80, 82, 84 as well as the loading body 86 are made of a metal material.
- the carrier 90 is made of a plastic material. This results in the situation that a force flow between the first component 12 and the second component 14 occurs exclusively via components made of metal material. This is illustrated in Figure 22 by means of two arrows Fl, F2.
- FIG. 23 shows a component connection 10 according to a further embodiment.
- the first component 12 with the first coupling groove 34 and the second component 14 with the second coupling groove 52 correspond to the components 12, 14 already explained with reference to Figures 9 and 10 with regard to the general shape of the coupling grooves 34, 52. Reference is made to these explanations.
- a connector 76 according to a fourth embodiment is used in the component connection 10 according to FIG. 23. This is shown in detail in Figure 24.
- the connector 76 again comprises a one-piece carrier 90 on which the loading body 86 is rotatably mounted.
- the loading body 86 is now essentially bolt-shaped, as will be explained later.
- the second engagement element 80 and the fourth engagement element 84 are also manufactured in one piece with the carrier 90.
- the articulated connection is realized by a film hinge 132, 134. A translational leadership the second engagement element 80 and the fourth engagement element 84 on the carrier 90 is therefore no longer necessary.
- 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 one another in order to be able to engage in the associated undercuts.
- the connector 76 includes a coupling element 136 in the form of a coupling slide 138.
- the coupling slide 138 includes a first wedge section 140, which is designed to spread the first engagement element 78 and the third engagement element 82 away from each other, so that these engagement elements 78, 82 can engage in the associated undercuts.
- a second wedge section 142 is provided on the coupling slide 138, which is designed to spread the second engagement element 80 and the fourth engagement element 84 away from each other, so that these engagement elements 80, 84 can engage in the associated undercuts.
- the coupling element 136 i.e. the coupling slide 138, is kinematically coupled to the loading body 86 via the primary cam mechanism 116.
- the primary cam gear 116 includes a cam surface 116a, which is arranged on an outer circumference of the bolt-shaped loading body 86 (see also FIG. 25).
- An associated counter surface 116b is formed by an inner circumference of an opening 144 on the coupling element 136, ie on the coupling slide 138 (see also FIG. 25).
- the coupling slide 138 is translationally displaced in such a way that its first wedge section 140 is pulled between the first engagement element 78 and the third engagement element 82 in such a way that they are spread apart from one another.
- the second wedge section 142 is pushed between the second engagement element 80 and the fourth engagement element 84 in such a way that they are spread apart from each other.
- the connector 76 includes a single secondary cam gear 124, which can also be referred to as a first secondary cam gear.
- the secondary cam mechanism 124 includes a cam surface 124a, which is arranged on an outer circumference of the bolt-shaped loading body 86.
- the cam surface 124a is arranged axially adjacent to the cam surface 116a with respect to a bolt center axis.
- An associated mating surface 124b is formed on the integral component comprising the first engagement element 78 and the third engagement element 82.
- FIG. 25 shows a process for producing the component connection 10 according to the embodiment from FIG. 23.
- the component connection 10 includes the connector 76 according to the fourth embodiment, as shown in FIGS. 23 and 24.
- FIG. 25 Three situations are shown in FIG. 25, which follow one another when producing the component connection 10. These situations are labeled a), b) and c). Each situation a), b), c) is illustrated using two sectional views. These are labeled (1) and (2) in each situation, with the cut being defined in the other figure, i.e. cut (1) is defined in representation (2) and vice versa.
- the connector 76 is inserted into both the first coupling groove 34 and the second coupling groove 52.
- the loading body 86 has already been rotated by approximately 65 degrees starting from an initial situation, which in the present example is done by means of the tool 72, which engages in the actuating element 88.
- the engagement elements 78, 80, 82, 84 are therefore spread by means of the primary cam mechanism 116 and the coupling slide 138, which includes the first wedge section 140 and the second wedge section 142, so that they fit into the respectively assigned undercuts 44, 48 , 62, 66 intervene.
- the associated cam surface 124a and the associated counter surface 124b abut one another, whereby a predetermined distance is established between the carrier 90 and the integral component comprising the first engagement element 78 and the third engagement element 82.
- the cam surface 124a and the counter surface 124b are held in contact with one another in that the coupling slide 138 spreads the first engagement element 78 and the third engagement element 82 away from one another by means of the first wedge and The integral component comprising the first engagement element 78 and the third engagement element 82 is also acted upon in the direction of the loading body 86.
- the loading body 86 was rotated by a further approximately 80 degrees compared to situation b).
- the coupling slide 138 was moved further by means of the primary cam gear 116.
- a further translational movement of the integral component comprising the first engagement element 78 and the third engagement element 82 was released relative to the carrier 90, so that the integral component comprising the first engagement element 78 and the third engagement element 82 is maximally inserted into the carrier 90 was moved in.
- the first contact surface 16 and the second contact surface 18 thus lie against each other under the application of force.
- the primary cam gear 116 and the secondary cam gear 124 can be designed to be self-locking.
- the first component 12 is thus reliably attached to the second component 14.
- a direction indicator 146 can optionally be provided on the loading body 86 and/or on the carrier 90, which indicates a direction of rotation of the loading body 86 corresponding to the closing direction of the connector 76.
- the direction indicator 146 includes three arrows. It is understood that even one or two of these arrows can form a useful directional indicator 146.
- the connector 76 may optionally have one or more position indicators 148. Based on the position indicators, it can be seen in which position the loading body 86 is located relative to the other components of the connector 76. This makes it possible to recognize whether the connector is in an open or closed position. Intermediate positions are also recognizable.
- the position indicator 148 comprises three short lines. Two of these lines are positioned on the carrier 90 and one of these lines is on the loading body 86 intended.
- Figure 26 shows further variants of the connector 76 according to the fourth embodiment.
- section XXVI from Figure 25 a) (1) is shown in an enlarged form in Figure 26 (a).
- the primary cam mechanism 116 can be seen there, which includes the cam surface 116a and the counter surface 116b.
- the coupling slide 138 is initially moved comparatively quickly by rotating the loading body 86.
- a comparatively high force must be applied in order to be able to rotate the loading body 86 further and thus to be able to move the coupling slide 138 further.
- a comparatively slow displacement of the coupling slide 138 takes place.
- the curve surface 116a includes a holding section 116e.
- the primary cam mechanism 116 can therefore be operated in two stages, with the cam surface 116a being moved in a first stage up to the associated holding holding section 116e, ie until the holding section 116e rests on the counter surface 116b. In a second stage, the loading body 86 is rotated further starting from this position.
- the holding section 116e can be configured in such a way that automatic movement of the components of the connector 76 is excluded when the holding section 116e rests on the counter surface 116b.
- the curve surface 116a includes a latching section 116f. This is composed of several flat surface segments. At the boundary lines between the individual surface segments there are no radii, but rather edges.
- Figure 25 (d) shows a variant in which a path along which the coupling slide 138 is displaced and the force required for this have a particularly uniform course. This is achieved in that there are no abrupt radius jumps in the effective area of the curved surface 116a, i.e. a radius of the curved surface 116a only changes continuously. The rate of change is comparatively small.
- FIG. 25 (e) Another variant is shown in Figure 25 (e).
- the coupling slide 138 is initially moved comparatively slowly by rotating the loading body 86. The necessary force also increases comparatively slowly. For this purpose, only a comparatively short section of the curved surface 116 is provided. An end position (see also Figure 25 b) and c)) is thus reached comparatively quickly.
- Figures 27 and 28 show a connector 76 according to a fifth embodiment. Here again only the differences compared to the connectors 76 already explained will be discussed.
- the connector 76 again comprises a one-piece carrier 90 on which the loading body 86 is rotatably mounted.
- the loading body 86 is also essentially bolt-shaped, more precisely circular-cylindrical.
- the first engagement element 78 and the third engagement element 82 are also formed by a common component which is elastically deformable at least in sections, as will be explained below.
- the second engagement element 80 and the fourth engagement element 84 are also formed by a common component, which is also elastically deformable at least in sections.
- the component through which the first engagement element 78 and the third engagement element 82 are formed and the component through which the second engagement element 80 and the fourth engagement element 84 are formed are separate from each other. In addition, these components are arranged at opposite ends of the carrier 90.
- the engagement elements 78, 80, 82, 84 are kinematically coupled to the loading body 86 via a gear transmission 150.
- the gear transmission 150 includes a drive gear 152, which in the present case is designed integrally with the loading body 86.
- a toothing of the drive gear 152 runs circumferentially completely around a jacket of the circular cylindrical loading body 86.
- the drive gear 152 is designed as a bevel gear.

- the drive gear 152 and the driven gear 158 mesh with each other.
- a central axis of the drive gear 152 and a central axis of the driven gear 158 run perpendicular to one another.
- a first threaded section 160 is provided at a first end of the threaded rod 156.
- a second threaded section 162 is provided at a second end of the threaded rod 156, which is opposite the first end.
- the first threaded section 160 is screwed into a threaded hole 164 of a first pressure piece 166.
- the second threaded section 162 is screwed into a threaded hole 168 of a second pressure piece 170.
- the first pressure piece 166 is guided linearly on the carrier 90 and arranged adjacent to the component that forms the first engagement element 78 and the third engagement element 82.
- the second pressure piece 170 is also linearly guided on the carrier 90 and arranged adjacent to the component that forms the second engagement element 80 and the fourth engagement element 84.
- the first pressure piece 166 can be moved towards or away from the component forming the first engagement element 78 and the third engagement element 82 in such a way that the first engagement element 78 and the third engagement element 82 emerge from the carrier 90 due to elastic deformation or retreat into the interior of the carrier 90 due to elastic deformation.
- the second pressure piece 170 can be moved towards or away from the component forming the second engagement element 80 and the fourth engagement element 84 in such a way that the second engagement element 80 and the fourth engagement element 84 protrude relative to the carrier 90 by elastic deformation or due to elastic deformation into the interior of the carrier 90.
- the engagement elements 78, 80, 82, 84 can engage or be disengaged in the respectively assigned undercuts 44, 48, 62, 66, provided the connector 76 is arranged in the coupling grooves 34, 52.
- Figures 29 and 30 show a variant of the component connection 10, in which the connector 76 according to the fifth embodiment is used.
- the connector 76 and the coupling grooves 34, 52 are only shown in a very simplified manner.
- first component 12 and the second component 14 are fastened to one another by the engagement elements 78, 80, 82, 84 in the respectively assigned undercuts 44, 48, 62 , 66 intervene.
