Description

Technical Field

[0001] The present invention relates to a connector for mechanically connecting a first workpiece and a second workpiece. The first workpiece includes at least one first engagement groove having a first undercut acting along the groove depth direction, and the second workpiece includes at least one second engagement groove having a second undercut acting along the groove depth direction.

[0002] The present invention also relates to an assembly. The assembly includes a first workpiece having at least one first coupling groove having a groove opening positioned in a first abutting surface of the first workpiece. The first coupling groove includes a first undercut acting along the groove depth direction. Additionally, the assembly includes a second workpiece having at least one second coupling groove having a groove opening positioned in a second abutting surface of the second workpiece. The second coupling groove includes a second undercut acting along the groove depth direction. Furthermore, the assembly includes a connector.

[0003] Furthermore, the present invention relates to a method for operating a connector. Background Technology

[0004] In this context, the groove depth direction is understood as the direction extending between the groove opening and the groove bottom. The groove opening is typically elongated. Otherwise, it is referred to as a hole or cavity. The groove opening is usually arranged opposite to the groove bottom. When the groove is restricted on both sides along its length, the groove opening is the only opening of the groove. When the groove has one or two opening ends along its length, the opening extending only along the length of the groove is considered the groove opening. Therefore, one or two opening ends do not form a groove opening. This also applies to openings created by other design features (e.g., transverse grooves or transverse holes). In this case, the direction parallel to the longer side of the elongated groove opening is considered the extension or length direction of the groove.

[0005] Therefore, the undercut acting along the groove depth direction includes the undercut relative to the direction extending from the bottom of the groove toward the groove opening. This means that the element engaging the undercut cannot be pulled out of the groove along the groove depth direction. This is because the element and the undercut form a forced lock.

[0006] Such undercuts and associated connecting grooves can be made using known methods and tools. The tools can be fixed or manually guided.

[0007] The connectors and components of the types described above are well known. They are used, for example, to mechanically connect wooden parts or workpieces. Such parts or workpieces can be furniture components. However, it should be understood that the connectors and components described above are not limited to specific categories of materials or specific application areas. They can also be used to connect parts or workpieces made of plastics, metals, ceramics, stone, etc.

[0008] In all conceivable applications, undercutting, which operates along the depth of the associated groove, offers the advantage of enabling highly reliable connection of workpieces. Rigid connections can be achieved through undercutting, especially compared to connection grooves without such undercutting. Summary of the Invention

[0009] The problem this invention aims to solve is to further improve known connectors. The connectors should be particularly suitable for use in confined spaces.

[0010] The aforementioned problem is solved by a connector for mechanically connecting a first workpiece and a second workpiece. The first workpiece includes at least one first engagement groove including a first undercut effective along the groove depth direction, and the second workpiece includes at least one second engagement groove including a second undercut effective along the groove depth direction. The connector is plate-shaped or flat rod-shaped. Furthermore, the connector includes a first engagement element for engaging the first undercut and a second engagement element for engaging the second undercut. Additionally, the connector includes an actuation body for selectively positioning the connector into a connected state where the first engagement element is positioned to engage the first undercut and the second engagement element is positioned to engage the second undercut, and for selectively positioning the connector into a released state where the connector is configured to withdraw from the first undercut and the second engagement element is configured to withdraw from the second undercut. The first and second engagement elements are arranged at opposite ends of the connector relative to the insertion direction of the connector. Furthermore, the first and second engagement elements are movably connected to the actuation body. An actuation interface is provided on the actuation body, which is eccentrically arranged along the insertion direction. Therefore, the eccentric arrangement means that the distance between the actuation interface and the first end of the connector is different from the distance between the actuation interface and the second end of the connector, where the first and second ends are opposite each other. In this case, the first undercut can be arranged adjacent to the bottom of the first coupling groove. Alternatively or additionally, the second undercut can be arranged adjacent to the bottom of the second coupling groove. Due to its plate shape or flat rod shape, the connector is particularly suitable for connecting workpieces via coupling grooves. In the installed state of the connector, with the connector inserted into the first coupling groove of the first workpiece and the second coupling groove of the second workpiece, the thickness direction of the connector, corresponding to the minimum spatial size of the connector, extends along the groove width direction, i.e., perpendicular to the length of the groove and perpendicular to the groove depth direction. This means that the connector can be used in workpieces where relatively little installation space may be available for the connector. In other words, a relatively compact connection can be achieved using this connector. The eccentric arrangement of the actuation interface along the insertion direction provides additional degrees of freedom. Since proximity to the actuation interface is required for the operation of the connector, the connector can be oriented relative to the first workpiece and relative to the second workpiece to ensure the necessary proximity to the actuation interface. Particularly for the connection of a first and second workpiece that are asymmetrical, an off-center orientation of the actuation interface can be advantageous because it improves accessibility compared to a symmetrical connector (i.e., a connector with an actuation interface centered along the insertion direction). This is especially suitable for using connectors to connect plate-shaped workpieces, particularly when the plate-shaped workpieces form corners. In such applications, the thickness direction of the connector extends, for example, parallel to the thickness direction of at least one plate-shaped workpiece.Furthermore, the plate shape or flat rod shape has the following advantages: the retaining force acting between the connector and each of the first and second workpieces is distributed over a relatively large section of the first and second workpieces. The retaining force is introduced into the respective workpieces via line contact or surface contact between the connector and the first and / or second workpieces. This results in relatively low mechanical stress within the first and / or second workpieces. Additionally, linear or surface contact between the connector and the first and / or second undercuts can be achieved. This results in a particularly strong and reliable connection between the first and second workpieces. The connector having both a first engagement element and a second engagement element, and providing a single actuating body for both engagement elements, also contributes to this. In this case, the actuating body can both position the engagement element within the corresponding assigned undercut (i.e., move the engagement element into the corresponding assigned undercut) and position the engagement element within the corresponding assigned undercut (i.e., move the engagement element within the corresponding assigned undercut) such that they are in the desired positions. In this case, when the connector is in the connected state, the first engagement element can be positioned relatively close to the actuation interface. This also applies to the second engaging element; that is, when the connector is in the connected state, the second engaging element can be positioned relatively close to the actuation interface. When the connector is in the released state, the first engaging element can be positioned further away from the actuation interface than in the connected state. This also applies to the second engaging element; that is, when the connector is in the released state, the second engaging element can be positioned further away from the actuation interface than in the connected state. Therefore, in the assembled state, the connector is simultaneously anchored in both the first and second workpieces; that is, the connector engages the first undercut of the first workpiece and the second undercut of the second workpiece. Therefore, the engaging element can also be referred to as an anchoring element or a gripper. On the one hand, such a connector structure is simple, which is beneficial for cost-effective production. On the other hand, such a connector is easy to use because workpieces can be quickly and easily attached to each other using such a connector.

[0011] It should be noted that the effects and advantages explained by the reference plate shape or flat rod shape are particularly relevant when compared to connectors with cylindrical or round rod shapes. This is because plate-shaped or flat rod-shaped connectors can couple to relatively large sections of the workpieces to be connected. In this case, the predetermined thickness of the workpiece means that at least one dimension of the connector cannot be arbitrarily increased. In the case of connectors with cylindrical or round rod shapes, this is typically the diameter. In the case of plate-shaped or flat rod-shaped connectors, only the associated thickness is limited by the thickness of the workpiece. Other dimensions of the connector can be adjusted substantially freely.

[0012] Furthermore, it should be understood that the first and second engaging elements must protrude at least in the assembled state (i.e., when the connector is in the connected state) and at least partially relative to other parts of the plate-like or flat rod-like connector in order to engage the associated undercut. Preferably, the first and second engaging elements protrude from other parts of the connector along the thickness direction of the connector.

[0013] In one variation, the first and second engaging elements are made of metallic material. This allows the engaging elements to be anchored with exceptionally high reliability in the associated engagement groove, particularly in the undercut located within the engagement groove.

[0014] According to one example, the actuation interface is configured for engagement with a tool. Therefore, the actuation interface, and thus the connector, can be actuated using a tool. Compared to manual actuation of the connector (i.e., actuation without a tool), this allows the user to apply a higher force and / or a higher torque to the actuation interface, and therefore to the first engagement element, to switch the first engagement element between a position associated with a connected state and a position associated with a released state. The same applies to the second engagement element; that is, the second engagement element can switch between a position associated with a connected state and a position associated with a released state. In summary, the connector is capable of operating with high reliability, i.e., with high reliability anchored in or released from the first and / or second workpieces.

[0015] According to one example, the actuation interface has a hexagonal shape, allowing it to interact with a hexagonal wrench or an L-shaped hexagonal wrench. According to another example, the actuation interface is slotted, allowing it to be operated using a screwdriver or a similar tool constructed as a groove.

[0016] According to one embodiment, the first and second engaging elements have different lengths along the insertion direction. As previously described, the first and second engaging elements are arranged at opposite ends of the connector relative to the insertion direction, and the actuation interface on the actuation body is arranged eccentrically along the insertion direction. Therefore, the different lengths of the first and second engaging elements provide a structurally simple and reliable construction for the connector. In other words, the different lengths of the first and second engaging elements are configured to bridge the distance difference between the ends of the connector along the insertion direction and the actuation interface.

[0017] In one example, the first engaging element travels a first distance when moving between a position associated with the connected state and a position associated with the released state. The second engaging element travels a second distance when moving between a position associated with the connected state and a position associated with the released state. The first and second distances are different. Therefore, when the connector is switched from the released state to the connected state, the first engaging element travels a longer distance than the second engaging element, and vice versa. This also applies when the connector is switched from the connected state to the released state. In other words, one engaging element travels a relatively larger distance, while the other engaging element travels a relatively shorter distance. This facilitates manipulating the connector and using a connector with an actuated interface including eccentric positioning to establish a connection between the first and second workpieces. Firstly, this is because when using a connector to establish a connection between the first and second workpieces, the first and second workpieces can be positioned a distance apart from each other. In other words, the connector can be used to connect the first and second workpieces even if there is a gap between them. This gap is eliminated by manipulating the connector and moving the first and second engaging elements along the corresponding distances. The fact that one engaging element travels a longer distance than the other allows the connector to be compact in the insertion direction. When operating the connector, the relative position between the connector and one of the first and second workpieces will be only slightly affected. The positioning of the connector relative to the other corresponding workpiece will be compensated for by the movement of the associated engagement element over a relatively large distance. Therefore, when using this connector, the user can essentially focus on the movement of the engagement element over a relatively long distance. This facilitates the establishment of a connection between the first and second workpieces using the connector.

[0018] In one embodiment, the connector has a length measured along the insertion direction, a width measured transversely to the insertion direction, and a thickness measured transversely to the insertion direction. The thickness is less than the width, and the ratio of width to length is 1 to 3, preferably 1.4 to 2. Therefore, to calculate the ratio of width to length, the width needs to be divided by the length. This ratio falls within the range of 1 to 3, where this range includes exactly 1 and exactly 3. This means that the width is exactly the same as or greater than the length, i.e., the ratio is 1 or greater. Additionally, the width is exactly three times or less than the length, i.e., the ratio is 3 or less. When the connector is plate-shaped or flat rod-shaped, the length, width, and thickness can therefore be determined by defining the minimum external dimension as the thickness. The external dimension oriented in the insertion direction is then defined as the length, and the remaining external dimension is defined as the width. The insertion direction is the direction in which the connector is inserted into one or more coupling grooves to connect associated workpieces. Therefore, such connectors are relatively short in the length direction. This means they can be used to connect workpieces that provide only relatively small space in the longitudinal direction (i.e., the insertion direction). This is especially true for flat workpieces and / or corner connectors.

[0019] The connector may also include a carrier body, wherein at least one of the first and second engaging elements is translatably supported on the carrier body. This means that at least one of the first and second engaging elements is mounted on the carrier body such that it is translatably displaceable relative to the carrier body. This translatability can be used to engage the engaging element with an associated undercut. Alternatively or additionally, in the case where the connector engages the associated undercut in the first and second workpieces, the translatability can be used to move the first and second workpieces toward each other. Thus, the first and second workpieces can be reliably positioned against each other.

[0020] In one example, the carrier includes at least one retaining portion for holding a first engaging element when the connector is in the connected state. Additionally or alternatively, the retaining portion is used to hold a second engaging element when the connector is in the connected state. This retaining portion prevents undesired movement and / or undesired deformation of the associated engaging element relative to the carrier when the connector is in the connected state. Therefore, at least one retaining portion can also be described as supporting the first engaging element and / or supporting the second engaging element when the connector is in the connected state. Preferably, the retaining portion supports the first engaging element at one or both lateral ends of the first engaging element. When the retaining portion supports the first engaging element at both lateral ends of the first engaging element, the actuating body is preferably positioned between the two opposing lateral ends of the first engaging element. The same applies to the second engaging element. Thus, a mechanically stable connection is provided between the connector and the first and / or second engaging elements. At least one retaining portion can be fixedly connected to the remainder of the carrier. Furthermore, it should be emphasized that at least one retaining portion is separate from the actuating body.

[0021] The actuating body can be rotatably supported on the first or second engaging element or on a carrier, allowing the actuating body to rotate about a rotation axis. All other degrees of freedom regarding the movement of the actuating body relative to the element on which it is rotatably supported (i.e., relative to the first, second, or carrier) may be restricted. Therefore, the only movement the actuating body can make relative to the first, second, or carrier is rotation. This is advantageous for actuating the actuating body, and thus for actuating the connector as a whole. Furthermore, the actuating body can be held in a defined position relative to the associated engaging element by the carrier. This connector is particularly reliable in function. Additionally, the carrier can be used to position the connector within the first and / or second engaging recesses. When the connector is positioned within the first and second engaging recesses using the carrier, the first and second workpieces can be positioned relative to each other by the carrier. The carrier can also be used to introduce force into the connector or transfer force away from the connector over a relatively large area. Therefore, the connector can connect the first and second workpieces via a high holding force; however, this only results in relatively low mechanical stress within the first and second workpieces. Preferably, the carrier is designed as a pair of half-shells, such that the actuating body can be at least partially accommodated between the two half-shells.

[0022] According to one embodiment, at least one of the first and second engagement elements is movably coupled to the actuating body via a transmission mechanism. The transmission mechanism allows movement of the actuating body to be translated into movement of the first and / or second engagement elements. This translation of movement is meaningful, meaning that the position or orientation of the actuating body can be reliably associated with the position or orientation of the first and / or second engagement elements. Preferably, both the first and second engagement elements are movably coupled to the actuating body via the transmission mechanism. The transmission mechanism can be designed as a common transmission mechanism, i.e., a transmission mechanism that associates both the first and second engagement elements with the actuating body. Alternatively, the transmission mechanism comprises two sub-mechanisms, one sub-mechanism associating the actuating body and the first engagement element with each other, and a second sub-mechanism associating the actuating body and the second engagement element with each other. Since the transmission of movement is meaningful, the first and / or second engagement elements can be reliably moved by actuating the actuating body. In summary, the connector can operate reliably.

[0023] The transmission mechanism may include a cam mechanism. Cam mechanisms are simple and robust in design. Furthermore, non-uniform and / or non-linear transmission can be achieved between the actuating body and at least one associated engaging element in this manner. Therefore, at least one extended position and at least one retracted position can be easily achieved via a cam mechanism.

[0024] In one example, the cam mechanism may have a cam surface disposed on the actuating body. Furthermore, the cam mechanism may have a mating surface associated with the cam surface. The mating surface may be disposed on at least one of a first engaging element and a second engaging element, or may be operatively connected to at least one of the first engaging element and the second engaging element. Thus, the mating surface is disposed directly on the associated engaging element or kinetically located on an intermediate element between the actuating body and the associated engaging element. In this case, the mating surface is associated with the cam surface if it is intended to contact the cam surface to form the cam mechanism, i.e., to transmit force between the actuating body and the corresponding engaging element. The cam surface and the mating surface may be of any shape, such as curved, to achieve any predetermined transformation between the movement of the actuating body and the movement of the associated engaging element.

[0025] The cam surface of the cam mechanism and the associated mating surface can be self-locked at least in a predetermined relative position. In this way, the associated engaging element can be held in a predetermined relative position relative to the actuating body by the cam mechanism.

[0026] The actuating body may include at least one actuating arm extending from the central portion of the actuating body. Thus, an actuating force can be applied precisely and reliably to the associated engagement element via this actuating arm. Furthermore, the actuating arm may form a lever element, through which a relatively small force acting on the actuation interface can be converted into a relatively large force acting on the associated engagement element.

[0027] The actuator arm can be made of metal. Such an actuator arm is suitable for particularly high forces and is particularly durable.

[0028] According to one variation, the cam surface of the cam mechanism is located at the free end of at least one actuating arm. The free end should be understood as the distal end of the actuating arm, i.e., the end opposite to the pivot point of the actuating arm. Therefore, the cam mechanism associated with the cam surface is actuated by the movement of the actuating arm.

[0029] The actuation body may include two actuation arms, one of which is associated with a first engagement element and the other with a second engagement element. The two actuation arms are of different lengths. Therefore, even though the actuation interface is in an off-center position, both the first and second engagement elements can be operated using their associated actuation arms.

[0030] The actuating body may include at least one abutment portion for supporting a first engaging element when the connector is in the released state. Additionally or alternatively, the actuating body may include at least one abutment portion for supporting a second engaging element when the connector is in the released state. Therefore, using such an abutment portion can influence the position and / or orientation of the associated engaging element. This means that such an abutment portion can prevent undesired position and / or orientation of the associated engaging element. In other words, the abutment portion ensures that the engaging element associated with that abutment portion is in the desired position in the released state. This facilitates reliable insertion of the connector into the first and / or second workpieces. Therefore, establishing a connection between the first and second workpieces is easy. In summary, the manipulation of the connector is enhanced.

[0031] The abutment portion can be located at the free end of the actuator arm or on the central portion of the actuator arm. As previously mentioned, the free end should be understood as the distal end of the actuator arm, i.e., the end of the actuator arm opposite to its pivot point. Conversely, the central portion of the actuator arm is the portion of the actuator arm located adjacent to its pivot point. Arranging the abutment portion on the actuator arm is structurally simple and allows the abutment portion to move in a manner that enables it to function in the released state and does not become an obstacle in the connected state of the connector.

[0032] According to one embodiment, the first engagement element and / or the second engagement element includes a locking element for locking the corresponding other of the first and second engagement elements in a position associated with a connection state of the connector. This covers three alternatives. In a first alternative, the first engagement element includes a locking element for locking the second engagement element in a position associated with a connection state of the connector. In a second alternative, the second engagement element includes a locking element for locking the first engagement element in a position associated with a connection state of the connector. A third alternative is a combination of the first and second alternatives. This means that in the third alternative, the first engagement element includes a locking element for locking the second engagement element in a position associated with a connection state of the connector, and the second engagement element includes a locking element for locking the first engagement element in a position associated with a connection state of the connector. The locking element may be integrally formed with the associated engagement element, i.e., integrally formed with the engagement element including the locking element. Preferably, the locking element extends from the first or second engagement element such that it engages or can engage a lateral end portion of the corresponding other of the first or second engagement element. In this case, the lateral end portions of the engagement element are located on opposite sides of the actuating body. Therefore, the locking element supports at least one lateral end portion of the corresponding other engaging element. Furthermore, when the connector is in the connected state, the locking element may be a protrusion abutting against or located near the engaging element to be locked. When the connector is in the released state, the locking element may not be in contact with the engaging element to be locked and / or may be located at a distance from it. In either case, in the released state of the connector, the locking element does not impede the movement of the engaging element to be locked. When the locking element is integrally formed with the associated engaging element, the locking element moves together with the associated engaging element when the connector transitions from the released state to the connected state or from the connected state to the released state. Thus, the locking element may move to a position where it locks or prevents the movement of the engaging element to be locked, or to a position where the movement of the engaging element can be locked. In all alternatives, when the connector is in the connected state, the use of the locking element allows at least one of the engaging elements to be locked. This means preventing the locked engaging element from leaving the position associated with the locked state of the connector. Additionally or alternatively, the locking element prevents undesirable deformation of the locked engagement element, which could occur without the locking element due to the forces generated by the engagement of the engagement element with the workpiece. In summary, the locking element enhances the reliability of the connection provided by the connector.

[0033] Note that the locking element of the first and / or second engaging element essentially performs the same function as the retaining portion described above; that is, when the connector is in the connected state, it locks or blocks the first and / or second engaging elements in a position associated with the connected state of the connector, making undesirable movement and / or deformation of the associated engaging elements relative to the carrier impossible. Therefore, the locking element of the first and / or second engaging element can also be designated as a retaining portion, the only difference being that the retaining portion described above is disposed on the carrier, while this retaining portion is disposed on the first and / or second engaging element. Specifically, this retaining portion is disposed on at least one lateral end portion of the first and / or second engaging element.

[0034] Furthermore, the aforementioned problem is solved by a component. This component includes a first workpiece comprising at least one first engagement groove having a groove opening positioned in a first abutment surface of the first workpiece. The first engagement groove includes a first undercut acting along the groove depth direction. Additionally, the component includes a second workpiece comprising at least one second engagement groove having a groove opening positioned in a second abutment surface of the second workpiece. The second engagement groove includes a second undercut acting along the groove depth direction. Furthermore, the component includes a connector according to the invention. The connector is partially disposed in the first engagement groove and partially disposed in the second engagement groove. A first engagement element of the connector engages the first undercut, and a second engagement element of the connector engages the second undercut. Furthermore, the first and second abutment surfaces are in contact with each other. As a result, the portion of the connector received in the first engagement groove and the portion of the connector received in the second engagement groove complement each other to form the entire connector. The undercut is preferably disposed adjacent to the bottom of the associated groove. Therefore, the first and second workpieces are attached to each other extremely reliably. Furthermore, since the connector is plate-shaped or flat rod-shaped, this connection saves space. The eccentric arrangement of the actuation interface along the insertion direction provides additional degrees of freedom. Since access to the actuation interface is required for connector operation, the connector can be oriented relative to both the first and second workpieces to ensure necessary access to the actuation interface. This can be achieved by positioning the actuation interface within one workpiece while allowing the depths of the engagement grooves in the first and second workpieces to be similar or identical. The eccentric orientation of the actuation interface can be particularly advantageous for connections involving asymmetrical first and second workpieces, as it improves accessibility compared to symmetrical connectors (i.e., connectors with an actuation interface centered along the insertion direction, where the access channel may have to be located in or very close to the joint between the first and second workpieces). This is especially suitable for using connectors to connect plate-shaped workpieces, particularly when the plate-shaped workpieces form corners. In such applications, the thickness direction of the connector extends parallel to the thickness direction of the plate-shaped workpiece. Furthermore, a plate shape or flat rod shape has the advantage that the retaining force acting between the connector and each of the first and second workpieces is distributed over a relatively large section of both workpieces. The retaining force is introduced into the respective workpieces via line contact between the connector and the first and / or second workpieces, or via surface contact between the connector and the first and / or second workpieces. This results in relatively low mechanical stress within the first and second workpieces. Additionally, linear or surface contact between the connector and the first and / or second undercuts can be achieved. This results in a particularly strong and reliable connection between the first and second workpieces.

[0035] In principle, the first and second workpieces can be joined together in any manner. In preferred variations, the abutment is designed as a corner joint, a butt joint, or a beveled joint. Particularly in the latter case, the plate shape or flat rod shape and the eccentric position of the actuation interface along the insertion direction are advantageous, as this facilitates the use of the connector for a beveled joint.

[0036] According to one example, an access channel for the tool is provided on the first workpiece and / or the second workpiece. The access channel extends from the outer surface of the respective first or second workpiece into the first and / or second coupling groove. Therefore, the actuating body, more precisely, the actuation interface of the actuating body, can be reliably reached via the access channel. This allows the connector to be reliably actuated.

[0037] In one variation, the access channel is formed as a cylindrical hole or drilled hole. This access channel can be created in a simple and reliable manner using a drill bit.

[0038] In another variation, the inlet channel opens in the direction of the associated contact surface. This inlet channel can also be referred to as a groove. This groove is oriented transversely to the associated connecting groove. It is not necessary to use a drilling gauge to create this transverse groove at a predetermined position relative to the connecting groove, as the groove can be created from the contact surface. Therefore, the transverse groove can be easily created using a grooving machine or a tenoning machine. Of course, the transverse groove, as well as the first and second connecting grooves, can also be created using an industrial CNC milling machine.

[0039] The actuation interface of the connector is preferably located at the end of the inlet channel. This means that the actuation interface can be easily reached with the associated tools.

[0040] Furthermore, the aforementioned problem is solved by a method for operating the connector. The connector is, in particular, a connector according to the present invention. The method includes:

[0041] - The connector is switched from a released state to a connected state, wherein a first engaging element of the connector travels a first distance when moving from a position associated with the released state to a position associated with the connected state, wherein a second engaging element of the connector travels a second distance when moving from a position associated with the released state to a position associated with the connected state, and wherein the first distance and the second distance are different, or

[0042] - The connector is switched from a connected state to a released state, wherein a first engaging element of the connector travels a first distance when moving from a position associated with the connected state to a position associated with the released state, wherein a second engaging element of the connector travels a second distance when moving from a position associated with the connected state to a position associated with the released state, and wherein the first distance and the second distance are different.

[0043] Therefore, when the connector is switched from the released state to the connected state, the first engaging element travels a longer distance than the second engaging element, and vice versa. This also applies when the connector is switched from the connected state to the released state. In other words, one engaging element travels a relatively larger distance, and the other engaging element travels a relatively shorter distance. This facilitates manipulating the connector and using it to establish a connection between the first and second workpieces, while ensuring a compact connector. Firstly, this is because when using the connector to establish a connection between the first and second workpieces, the first and second workpieces can be positioned a certain distance apart from each other. In other words, even if there is a gap between the first and second workpieces, the connector can be used to connect them. This gap is eliminated by manipulating the connector and moving the first and second engaging elements along the corresponding distances. The longer distance traveled by one engaging element compared to the other allows for relatively high precision in positioning the connector relative to one of the first and second workpieces. When the connector is manipulated, the relative position between the connector and this one of the first and second workpieces will be only slightly affected, resulting in only a small displacement or no displacement of the actuation interface relative to the inlet channel. The positioning of the connector relative to the corresponding other workpiece does not need to adhere to the same precision standard. This is compensated for by the movement of the associated engaging element over a relatively large distance. Therefore, when using this connector, the user can essentially focus on the movement of the engaging element over a relatively long distance. This facilitates the establishment of a connection between the first and second workpieces using this connector.

[0044] In one example, the method further includes locking the first and / or second engagement elements in a position associated with the connector's connection state. Alternatively, the method also includes enabling movement of the first and / or second engagement elements from the position associated with the connector's connection state to a position associated with the connector's release state. Locking the first and / or second engagement elements in the corresponding positions associated with the connector's connection state enhances the reliability of the connection provided by the connector. This is because locking prevents the locked engagement elements from leaving that position. Furthermore, locking prevents undesirable deformation of the locked engagement elements, which could occur without the locking element due to the forces generated by the engagement of the engagement elements with the workpiece. Since the first and / or second engagement elements can also be selectively moved from the position associated with the connector's connection state to the position associated with the connector's release state—that is, since the first and / or second engagement elements can also be unlocked—the connector can still be easily withdrawn from the workpiece. Overall, the reliability of the connection established using the connector is increased without compromising the ease of operation of the connector.

[0072] Figure 1 Component 10 according to the first embodiment is shown.

[0073] The component includes a first workpiece 12 and a second workpiece 14.

[0074] A first abutting surface 16 is provided on the first workpiece 12.

[0075] The second workpiece 14 includes a second abutting surface 18.

[0076] With the first workpiece 12 and the second workpiece 14 attached to each other, the first abutting surface 16 and the second abutting surface 18 come into contact with each other, so that the first workpiece 12 and the second workpiece 14 form a corner.

[0077] The first workpiece 12 has a first connecting groove 20 (see also...) Figure 2 ).

[0078] The groove opening 22 of the first connecting groove 20 is located in the first abutting surface 16.

[0079] The groove depth direction 24 of the first connecting groove 20 is perpendicular to the first abutting surface 16.

[0080] The first connecting groove 20 also includes a first undercut 26, which acts along the groove depth direction 24 and is arranged adjacent to the groove bottom 28 of the first connecting groove 20.

[0081] In the illustrated embodiment, the first undercut 26 is designed as a transverse groove extending along the bottom 28 of the groove, wherein the groove depth direction 30 of the transverse groove is oriented perpendicular to the groove depth direction 24 of the first connecting groove 20 and parallel to the first abutment surface 16.

[0082] The first connecting groove 20 also has a third undercut 32, which acts along the groove depth direction 24 and is arranged adjacent to the bottom 28 of the groove. The third undercut 32 is disposed on the wall of the first connecting groove 20 opposite to the first undercut 26.

[0083] In the illustrated embodiment, the third undercut 32 is designed as a transverse groove extending along the bottom 28 of the groove, wherein the groove depth direction 34 of the transverse groove is oriented perpendicular to the groove depth direction 24 of the first connecting groove 20 and parallel to the first abutment surface 16.

[0084] Furthermore, the groove depth direction 30 of the transverse groove forming the first undercut 26 and the groove depth direction 34 of the groove forming the third undercut 32 are oriented in parallel.

[0085] It should be noted that designating the undercut as the third undercut 32 is merely for ease of interpretation and does not imply many undercuts.

[0086] The second workpiece 14 has a second connecting groove 36, the groove opening 38 of which is located in the second abutting surface 18 (see also...). Figure 2 ).

[0087] With the first workpiece 12 and the second workpiece 14 attached to each other, the groove opening 38 of the second connecting groove 36 is arranged opposite to the groove opening 22 of the first connecting groove 20.

[0088] The groove depth direction 40 of the second connecting groove 36 is oriented perpendicular to the second abutment surface 18.

[0089] The second connecting groove 36 also includes a second undercut 42, which acts along the groove depth direction 40 and is arranged adjacent to the groove bottom 44 of the second connecting groove 36.

[0090] In the illustrated embodiment, the second undercut 42 is designed as a transverse groove extending along the bottom 44 of the groove, wherein the groove depth direction 46 of the transverse groove is oriented perpendicular to the groove depth direction 40 of the second connecting groove 36 and parallel to the second abutment surface 18.

[0091] The second connecting groove 36 also has a fourth undercut 48, which acts along the groove depth direction 40 and is arranged adjacent to the bottom 44 of the groove. The fourth undercut 48 is disposed on the wall of the second connecting groove 36 opposite to the second undercut 42.

[0092] In the illustrated embodiment, the fourth undercut 48 is designed as a transverse groove extending along the bottom 44 of the groove, wherein the groove depth direction 50 of the transverse groove is oriented perpendicular to the groove depth direction 40 of the second connecting groove 36 and parallel to the second abutment surface 18.

[0093] Furthermore, the groove depth direction 46 of the transverse groove forming the second undercut 42 and the groove depth direction 50 of the groove forming the fourth undercut 48 are oriented parallel to each other.

[0094] It should be noted that designating undercuts as the second undercut 42 and the fourth undercut 48 is merely for ease of interpretation and does not imply many undercuts.

[0095] Furthermore, a tool access channel 52 is provided on the second workpiece 14. In the example shown in the figure, the tool may be a so-called L-shaped hex wrench, which should only be understood as an example.

[0096] The access channel 52 extends from the outer surface 54 of the second workpiece 14, which in the example shown is oriented perpendicular to the second abutment surface 18.

[0097] In addition, the access channel 52 extends into the second connecting groove 36.

[0098] In other words, the entry channel 52 penetrates the side wall of the second connecting groove 36.

[0099] Therefore, the tool (in this example, an L-shaped hex wrench) can reach the connector arranged in the second coupling recess 36 via the access channel 52, as will be explained further below.

[0100] In the example shown in the figure, the entry channel 52 is formed as a drill hole.

[0101] Component 10 also includes a connector 56 according to the first embodiment (see also) Figures 3 to 7 ).

[0102] Connector 56 has an overall plate-like form. In other words, when considering the overall form of connector 56, connector 56 is plate-shaped.

[0103] More specifically, connector 56 has a length L1 measured along the insertion direction D. Additionally, connector 56 has a width L2 measured transversely to the insertion direction D and a thickness L3 also measured transversely to the insertion direction D.

[0104] Thickness L3 is always less than width L2. Therefore, thickness L3 is always the minimum external dimension of connector 56.

[0105] The ratio of width L2 to length L1 is between 1 and 3. In a preferred variation, this ratio is between 1.4 and 2. Therefore, width L2 is exactly the same as or greater than length L1.

[0106] Connector 56 includes a carrier 58, which in this example is made of plastic material.

[0107] Furthermore, in the example shown in the figure, the carrier 58 can be designed as a single piece. Alternatively, the carrier 58 may comprise two carrier half-shells connected to each other to form a carrier. In this case, the two carrier half-shells may be connected via one or more welds (e.g., ultrasonic welds), one or more clips, or one or more adhesive joints. Combinations of these connection alternatives are also possible.

[0108] The support body 58 includes a first double T-shaped wall element 60 having a first support opening 62 and a second double T-shaped wall element 64 having a second support opening 66.

[0109] Two wall elements 60 and 64 are arranged opposite each other at a certain distance, and each is connected to the connecting sections 68 and 70 at two corresponding opposite ends.

[0110] Therefore, connecting section 68 connects the top portions of the opposing T-shaped portions 72, 74 of the first wall element 60 and the second wall element 64. In other words, connecting section 68 connects the horizontal bars of the T-shaped portions 72, 74 of the first wall element 60 and the second wall element 64.

[0111] The same applies to connecting section 70. Therefore, connecting section 70 connects the top portions of the opposing T-shaped portions 72, 74 of the first wall element 60 and the second wall element 64. In other words, connecting section 70 connects the horizontal bars of the T-shaped portions 72, 74 of the first wall element 60 and the second wall element 64.

[0112] In connector 56, the top portions of T-shaped portions 72 and 74 and the connecting sections 68 and 70 extend substantially along the insertion direction D of connector 56.

[0113] The branch element 76 of the T-shaped portion 72 of the first wall element 60 is arranged eccentrically relative to the insertion direction D of the connector 56. (Reference) Figure 3This means that the branch elements 76 of the T-shaped portions 72 and 74 are arranged closer to the lower end of the carrier 58 than to the upper end of the carrier 58. In other words, the branch elements 76 of the T-shaped portions 72 and 74 are arranged closer to one end of the connector 56 along the length L1 than to the opposite end of the connector 56 along the length L1.

[0114] This also applies to the branch element 76 of the T-shaped portion 74 of the second wall element 64.

[0115] In other words, the T-shaped portions 72 and 74 are not symmetrical because the branch element 76 of the T-shaped portions 72 and 74 (i.e., the portion of the T-shaped portions 72 and 74 that corresponds to the normally vertical rod of the T-shape) is off-center.

[0116] When connector 56 is arranged within the first connecting groove 20 and / or the second connecting groove 36, the two connecting sections 68 and 70 are designed to contact the corresponding opposite ends of the first connecting groove 20 and / or the second connecting groove 36. In this case, the opposite ends of the first connecting groove 20 are understood as the ends of the first connecting groove 20 along its length. In this example, the length of the first connecting groove is oriented perpendicular to the groove depth direction 24 of the first connecting groove 20, and also perpendicular to the depth directions 30 and 34 of the transverse grooves forming the undercuts 26 and 32. Similarly, the opposite ends of the second connecting groove 36 are understood as the ends of the second connecting groove 36 along its length. In this example, the length of the second connecting groove is oriented perpendicular to the groove depth direction 40 of the second connecting groove 36, and also perpendicular to the depth directions 46 and 50 of the transverse grooves forming the undercuts 42 and 48. Therefore, the first workpiece 12 and the second workpiece 14 can be brought to a predetermined relative position by the carrier 58.

[0117] The connector 56 also includes a first engagement element 78 configured to anchor the connector 56 in a first undercut 26, a second engagement element 80 configured to anchor the connector 56 in a second undercut 42, a third engagement element 82 configured to anchor the connector 56 in a third undercut 32, and a fourth engagement element 84 configured to anchor the connector 56 in a fourth undercut 48.

[0118] Therefore, the first engaging element 78 includes engaging rib 78a, the second engaging element 80 includes engaging rib 80a, the third engaging element 82 includes engaging rib 82a, and the fourth engaging element 84 includes engaging rib 84a.

[0119] Considering the insertion direction D, the first engagement element 78 and the third engagement element 82 are arranged at the first end of the connector 56, and the second engagement element 80 and the fourth engagement element 84 are arranged at the second end of the connector 56. The first end and the second end are arranged opposite to each other in the direction of thickness L3.

[0120] In addition, the connector 56 has an actuation body 86 supported in a first support opening 62 and a second support opening 66 of the carrier 58, such that the actuation body 86 can rotate relative to the carrier 58 about axis A.

[0121] The axis A is oriented parallel to the thickness L3 of the connector 56, that is, perpendicular to the insertion direction D and the width L2.

[0122] The actuating body 86 includes a first actuating arm 88 and a second actuating arm 90, both extending from the central portion 92 of the actuating body 86.

[0123] The first actuator 88 and the second actuator 90 extend in opposite directions in diameter relative to the axis of rotation A.

[0124] Therefore, the first actuating arm 88 and the second actuating arm 90 can also rotate around the rotation axis A.

[0125] In this example, the first actuating arm 88 and the second actuating arm 90 have different lengths A1 and A2. More precisely, the length A1 of the first actuating arm 88 is greater than the length A2 of the second actuating arm 90, where lengths A1 and A2 are measured in the radial direction relative to the axis of rotation A.

[0126] Furthermore, as will be explained in more detail below, the first actuating arm 88 is associated with the first engaging element 78 and the third engaging element 82. The second actuating arm 90 is associated with the second engaging element 80 and the fourth engaging element 84.

[0127] Furthermore, the actuation interface 94 is disposed on the actuation body 86, or more precisely, on the central portion 92 of the actuation body 86.

[0128] In the illustrated embodiment, the actuation interface 94 is designed as a blind hole with a hexagonal cross-section. The dimensions of this cross-section allow it to mate with an L-shaped hexagonal wrench.

[0129] Since the branch element 76, the first support opening 62 and the second support opening 66 are arranged eccentrically relative to the insertion direction D, the actuation interface 94 is also arranged eccentrically relative to the insertion direction D.

[0130] Each engagement element 78, 80, 82, 84 is designed as an independent component. In particular, engagement elements 78, 80, 82, 84 are designed as components separate from the actuation body 86.

[0131] Each of the joining elements 78, 80, 82, and 84 is essentially plate-shaped.

[0132] However, since the actuation interface 94 is eccentrically arranged relative to the insertion direction D, the first engagement element 78 and the third engagement element 82 are longer along the insertion direction D than the second engagement element 80 and the fourth engagement element 84.

[0133] In addition, each engagement element 78, 80, 82, 84 is mounted on the carrier 58 so that it can be translated along the insertion direction D.

[0134] Therefore, connecting sections 68 and 70 form guide rails 96 and 98.

[0135] Although the main displacement direction corresponds to the insertion direction D, the guide rails 96 and 98 also allow displacement perpendicular to the insertion direction D, i.e., displacement in the direction of thickness L3, which is necessary for the engagement elements 78, 80, 82, and 84 to engage one of the associated undercuts 26, 32, 42, and 48.

[0136] In connector 56, actuation body 86 is kinematically connected to each engagement element 78, 80, 82, 84 via main cam mechanisms. Thus, a total of four main cam mechanisms are provided.

[0137] All main cam mechanisms are configured to insert associated engagement elements 78, 80, 82, 84 into associated undercuts 26, 32, 42, 48 when the connector 56 is positioned in the first engagement groove 20 and the second engagement groove 36.

[0138] More specifically, the first engagement element 78 is kinematically coupled to the actuating body 86 via the first main cam mechanism 102, or more specifically to the first actuating arm 88.

[0139] In this configuration, the first master cam mechanism 102 includes a cam surface 102a disposed at the free end of the first actuator arm 88. The cam surface 102a extends obliquely relative to the circumferential direction of the first actuator arm 88, which is rotatable about the axis of rotation A.

[0140] An associated mating surface 102b is disposed on the first engaging element 78. More specifically, the mating surface 102b is formed on the inner side of the first engaging element 78, that is, on the side of the first engaging element 78 facing the interior of the connector 56.

[0141] If the cam surface 102a slides against the mating surface 102b, the first engagement element 78 is thus displaced outward relative to the carrier 58, i.e., along the thickness L3 direction. Therefore, the first engagement element 78 transitions to its extended position along the thickness L3 direction of the connector 56.

[0142] Similarly, the second engagement element 80 is kinematically coupled to the actuating body 86, or more precisely, to the second actuating arm 90, via the second main cam mechanism 104.

[0143] In this configuration, the second master cam mechanism 104 includes a cam surface 104a disposed at the free end of the second actuator arm 90. The cam surface 104a extends obliquely relative to the circumferential direction of the second actuator arm 90, which is rotatable about the rotation axis A.

[0144] An associated mating surface 104b is disposed on the second engaging element 80. More specifically, the mating surface 104b is formed on the inner side of the second engaging element 80, that is, on the side of the second engaging element 80 facing the interior of the connector 56.

[0145] If the cam surface 104a slides against the mating surface 104b, the second engagement element 80 is thus displaced outward relative to the carrier 58, i.e., along the thickness L3 direction. Therefore, the second engagement element 80 transitions to its extended position along the thickness L3 direction of the connector 56.

[0146] Therefore, the third engagement element 82 is kinematically connected to the actuating body 86, or more precisely, to the first actuating arm 88, via the third main cam mechanism 106.

[0147] In this configuration, the third master cam mechanism 106 includes a cam surface 106a disposed at the free end of the first actuator arm 88. The cam surface 106a extends obliquely relative to the circumferential direction of the first actuator arm 104, which is rotatable about the axis of rotation A.

[0148] An associated mating surface 106b is disposed on the third engaging element 82. More specifically, the mating surface 106b is formed on the inner side of the third engaging element 82, that is, on the side of the third engaging element 82 facing the interior of the connector 56.

[0149] If the cam surface 106a slides against the mating surface 106b, the third engagement element 82 displaces outward relative to the carrier 58, i.e., along the thickness L3 direction. Therefore, the third engagement element 82 transitions to its extended position along the thickness L3 direction of the connector 56.

[0150] In this case, cam surface 102a and cam surface 106a are arranged on opposite sides of the head 88a of the first actuator arm 88.

[0151] When viewed radially, the head 88a has a wedge shape that is beveled on both sides (i.e., on the side facing the first engaging element 78 and on the side facing the third engaging element 82). Therefore, by actuating the first actuating arm 88, the head 88a can be pushed like a wedge between the first engaging element 78 and the third engaging element 82, so that they are pushed apart by means of the head 88a, thus presenting their extended positions along the thickness L3 of the connector 56.

[0152] Furthermore, the fourth engagement element 84 is kinematically connected to the actuating body 86 via the fourth main cam mechanism 108, and more specifically to the second actuating arm 90.

[0153] Here, the fourth master cam mechanism 108 includes a cam surface 108a disposed at the free end of the second actuator arm 90. The cam surface 108a extends obliquely relative to the circumferential direction of the second actuator arm 90, which is rotatable about the rotation axis A.

[0154] An associated mating surface 108b is disposed on the fourth engaging element 84. More specifically, the mating surface 108b is formed on the inner side of the fourth engaging element 84, that is, on the side of the fourth engaging element 84 facing the interior of the connector 56.

[0155] If the cam surface 108a slides against the mating surface 108b, the fourth engagement element 84 is displaced outward relative to the carrier 58. Therefore, the fourth engagement element 84 transitions to its extended position along the thickness L3 of the connector 56.

[0156] In this case, cam surface 104a and cam surface 108a are arranged on opposite sides of the head 90a of the second actuator arm 90.

[0157] When viewed radially, the head 90a has a wedge shape that is beveled on both sides (i.e., on the side facing the second engagement element 80 and on the side facing the fourth engagement element 84). Therefore, by actuating the second actuating arm 90, the head 90a can be pushed like a wedge between the second engagement element 80 and the fourth engagement element 84, such that the second engagement element 80 and the fourth engagement element 84 are pushed apart by means of the head 90a, thus presenting their extended positions along the thickness L3 of the connector 56.

[0158] Furthermore, in the connector 56 according to the first embodiment, the actuating body 86 is kinematically connected to each engaging element 78, 80, 82, 84 via a secondary cam mechanism.

[0159] All auxiliary cam mechanisms are configured to translate the associated engagement elements 78, 80, 82, 84 toward the center point of connector 56 or toward the axis of rotation A along a direction predetermined by the respective guides 96, 98, substantially corresponding to the insertion direction D. Thus, the auxiliary cam mechanisms cause the respective associated engagement elements 78, 80, 82, 84 to shift to their retracted position along the insertion direction D.

[0160] With the connector 56 positioned in the first connecting groove 20 and the second connecting groove 36, and the engaging elements 78, 80, 82, 84 engaging the corresponding associated undercuts 26, 32, 42, 48, the first workpiece 12 and the second workpiece 14 can move toward each other and / or press against each other via the secondary cam mechanism.

[0161] More specifically, the first engagement element 78 is kinematically connected to the actuating body 86 via the first auxiliary cam mechanism 110, and more specifically to the first actuating arm 88.

[0162] In this configuration, the first cam mechanism 110 includes a cam surface 110a disposed at the free end of the first actuating arm 88. The cam surface 110a is formed on the radially inward side of the head 88a of the first actuating arm 88 and is curved. The axis of curvature extends parallel to the axis of rotation A.

[0163] An associated mating surface 110b is arranged on a protrusion on the inner side of the first engaging element 78. The mating surface 110b points radially outward relative to the axis of rotation A.

[0164] The mating surface 110b also bends around a curvature axis that extends parallel to the axis of rotation A.

[0165] If the cam surface 110a slides on the mating surface 110b, the first engaging element 78 is thus pulled inward relative to the carrier 58, i.e., in the direction of the rotation axis A. As a result, the first engaging element 78 is switched to the retracted position relative to the insertion direction D of the connector 56.

[0166] The second engagement element 80 is kinematically connected to the actuating body 86, or more precisely, to the second actuating arm 90, via the second auxiliary cam mechanism 112.

[0167] In this configuration, the second auxiliary cam mechanism 112 includes a cam surface 112a disposed at the free end of the second actuating arm 90. The cam surface 112a is formed on the radially inward side of the head 90a of the second actuating arm 90 and is curved. The axis of curvature extends parallel to the axis of rotation A.

[0168] An associated mating surface 112b is arranged on a protrusion on the inner side of the second engaging element 80. The mating surface 112b points radially outward relative to the axis of rotation A.

[0169] The mating surface 112b also bends around a curvature axis that extends parallel to the axis of rotation A.

[0170] If the cam surface 112a slides on the mating surface 112b, the second engagement element 80 is thus pulled inward relative to the carrier 58, i.e., in the direction of the rotation axis A. As a result, the second engagement element 80 is switched to the retracted position relative to the insertion direction D of the connector 56.

[0171] The third engagement element 82 is also kinematically connected to the actuating body 86, or more precisely, to the first actuating arm 88, via the third auxiliary cam mechanism 114.

[0172] In this configuration, the third cam mechanism 114 includes a cam surface 114a disposed at the free end of the first actuating arm 88. The cam surface 114a is formed on the radially inward side of the head 88a of the first actuating arm 88 and is curved. The axis of curvature extends parallel to the axis of rotation A.

[0173] An associated mating surface 114b is arranged on a protrusion on the inner side of the third engaging element 82. The mating surface 114b points radially outward relative to the axis of rotation A.

[0174] The mating surface 114b also bends around a curvature axis that extends parallel to the axis of rotation A.

[0175] If the cam surface 114a slides on the mating surface 114b, the third engagement element 82 is pulled inward relative to the carrier 58, i.e., in the direction of the rotation axis A. As a result, the third engagement element 82 is switched to the retracted position relative to the insertion direction D of the connector 56.

[0176] Furthermore, the fourth engagement element 84 is kinematically connected to the actuating body 86, or more precisely, to the second actuating arm 90, via the fourth auxiliary cam mechanism 116.

[0177] The fourth cam mechanism 116 includes a cam surface 116a disposed at the free end of the second actuating arm 90. The cam surface 116a is formed on the radially inward side of the head 90a of the second actuating arm 90 and is curved. The axis of curvature extends parallel to the axis of rotation A.

[0178] An associated mating surface 116b is arranged on a protrusion on the inner side of the fourth engaging element 84. The mating surface 116b points radially outward relative to the axis of rotation A.

[0179] The mating surface 116b also bends around a curvature axis that extends parallel to the axis of rotation A.

[0180] If the cam surface 116a slides on the mating surface 116b, the fourth engagement element 84 is pulled inward relative to the carrier 58, i.e., in the direction of the rotation axis A. As a result, the fourth engagement element 84 is switched to the retracted position relative to the insertion direction D of the connector 56.

[0181] The actuating body 86 further includes a first abutment portion 118 for supporting the first engagement element 78 and the third engagement element 82 when the connector 56 is in the released state. In this state, the first engagement element 78 and the third engagement element 82 can be supported on the first abutment portion 118 along the insertion direction D.

[0182] The first contact portion 118 is formed as a protrusion on the central portion 92 of the actuating body 86.

[0183] The actuating body 86 also includes a second abutment portion 120 for supporting the second engagement element 80 and the fourth engagement element 84 when the connector 56 is in the released state. In this state, the second engagement element 80 and the fourth engagement element 84 can be supported on the second abutment portion 120 along the insertion direction D.

[0184] Similarly, the second abutment portion 120 is formed as a protrusion on the central portion 92 of the actuating body 86. Preferably, the second abutment portion 120 and the first abutment portion 118 are formed on opposite sides of the actuating body 86 in diameter.

[0185] When the main cam mechanisms 102, 104, 106, 108 and / or the secondary cam mechanisms 110, 112, 114, 116 are not in operation, for example, because the actuator arms 88, 90 are in a position where they do not contact the engagement elements 78, 80, 82, 84 or the engagement elements 78, 80, 82, 84 are in a position associated with the release state, the first abutment portion 118 and the second abutment portion 120 are particularly operable, i.e., abut against the corresponding associated engagement elements 78, 80, 82, 84.

[0186] Returning to the carrier 58, the carrier 58 further includes a plurality of retaining portions 122 configured to retain the first engagement element 78 when the connector is in a connected state. In this example, the retaining portions 122 are geometric elements of the carrier 58 that prevent movement of the engagement element 78 in the direction of the thickness L3 of the connector 56.

[0187] This also applies to the third coupling element 82.

[0188] However, the retaining portion 122 is not designed to interact with the second engaging element 80 and the fourth engaging element 84. Therefore, in the connected state, the second engaging element 80 and the fourth engaging element 84 do not contact any of the retaining portions 122.

[0189] When the first engaging element 78 and the third engaging element 82 are in the position associated with the released state of the connector 56, or when the first engaging element 78 and the third engaging element 82 are switched to the position associated with the released state of the connector 56, in order to allow the first engaging element 78 and the third engaging element 82 to pass through the retaining portion 122, both the first engaging element 78 and the third engaging element 82 are provided with recesses 126, which are arranged such that when the first engaging element 78 and the third engaging element 82 are in the position associated with the released state of the connector 56, a retaining portion 122 can be received at least partially in an associated recess 126.

[0190] Similar to retaining portion 122, it is also conceivable that carrier 58 includes a plurality of retaining portions configured to retain the second engagement element 80 and the fourth engagement element 84 when connector 56 is in a connected state. These retaining portions are configured to prevent movement of the second engagement element 80 and the fourth engagement element 84 in the direction of thickness L3 of connector 56.

[0191] In component 10, the first workpiece 12 and the second workpiece 14 are fastened together by connector 56.

[0192] In order to form component 10, connector 56 is partially inserted into second coupling groove 36.

[0193] In this state, the actuation interface 94 is positioned at the end of the connection groove of the inlet channel 52.

[0194] In addition, another part of the connector 56 is arranged in the first connection groove 20.

[0195] Therefore, connector 56 is accommodated within the first connection groove 20 and the second connection groove 36.

[0196] The actuating body 86 is positioned such that the first abutting portion 118 contacts the first engaging element 78 and the third engaging element 82, and the second abutting portion 120 contacts the second engaging element 80 and the fourth engaging element 84. Therefore, even though the first engaging element 78 and the third engaging element 82 contact the bottom 28 of the first connecting groove 20, and the second engaging element 80 and the fourth engaging element 84 contact the bottom 44 of the second connecting groove 36, a relatively small gap is provided between the first workpiece 12 and the second workpiece 14.

[0197] The head 88a of the first actuating boom 88 and the head 90a of the second actuating boom 90 have not yet interacted with the engagement elements 78, 80, 82, 84.

[0198] The coupling elements 78, 80, 82, and 84 have not yet been coupled into the associated undercuts 26, 32, 42, and 48.

[0199] Furthermore, the connecting sections 68 and 70 each contact one lateral end of the first connecting groove 20 and one lateral end of the second connecting groove 36. Therefore, the first workpiece 12 and the second workpiece 14 are positioned relative to each other according to a predetermined plan.

[0200] Now, the actuating body 86 can rotate clockwise by approximately 15 degrees. Therefore, the clockwise direction corresponds to the actuation direction of the actuating body 86.

[0201] In this case, the actuation body 86 can be rotated, for example, by means of a tool that engages the actuation interface 94.

[0202] Therefore, the engaging elements 78, 80, 82, 84 are now pushed open by the corresponding associated main cam mechanisms 102, 104, 106, 108, so that they engage in the corresponding associated undercuts 26, 32, 42, 48.

[0203] With respect to the secondary cam mechanisms 110, 112, 114, and 116, the associated cam surfaces 110a, 112a, 114a, and 116a are in contact with the associated mating surfaces 110b, 112b, 114b, and 116b in the forward section along the actuation direction. However, these sections are configured such that the secondary cam mechanisms 110, 112, 114, and 116 have not yet caused any movement of the engaging elements 78, 80, 82, and 84 along the insertion direction D. Furthermore, the abutment portions 118 and 120 prevent any movement of the engaging elements 78, 80, 82, and 84 towards the rotation axis A along the insertion direction D.

[0204] Subsequently, the actuator 86 rotates further clockwise by approximately 90 degrees.

[0205] In this situation, the abutment portions 118 and 120 disengage from the corresponding associated engagement elements 78, 80, 82, and 84, and the cam surfaces 110a, 112a, 114a, and 116a of the sub-cam mechanisms 110, 112, 114, and 116 interact with the sections of the associated mating surfaces 110b, 112b, 114b, and 116b, causing the engagement elements 78, 80, 82, and 84 to be translated and pulled in the direction of the rotation axis A by the sub-cam mechanisms 110, 112, 114, and 116.

[0206] In this example, the secondary cam mechanisms 110, 112, 114, and 116 are configured such that the first engagement element 78 and the third engagement element 82 travel a first distance T1 when moving from a position associated with the released state to a position associated with the engaged state.

[0207] The second engagement element 80 and the fourth engagement element 84 travel a second distance T2 when moving from a position associated with the release state to a position associated with the connection state.

[0208] In this example, the first distance T1 is greater than the second distance T2.

[0209] This causes the first contact surface 16 and the second contact surface 18 to come into contact with each other. This contact can be achieved by applying a force.

[0210] Meanwhile, the first engagement element 78 and the third engagement element 82 abut against the opposite sides of the retaining portion 122 along the direction of the thickness L3 of the connector 56.

[0211] In this position, the secondary cam mechanisms 110, 112, 114, and 116 can also be designed to be self-locking. Therefore, the first workpiece 12 is reliably fixed to the second workpiece 14.

[0212] In order to transition the connector 56 from the connected state to the released state in which the first workpiece 12 and the second workpiece 14 can be separated from each other and the connector 56 can also be separated from the first workpiece 12 and the second workpiece 14, the actuating body 86 needs to rotate in the opposite direction, that is, counterclockwise.

[0213] Figures 8 to 10 Component 10 according to the second embodiment is shown. In the following, only the differences from the embodiments described above will be explained. Otherwise, the above explanations, with necessary modifications, apply.

[0214] The first difference involves the formation of a beveled joint between the first workpiece 12 and the second workpiece 14.

[0215] This means that the first abutting surface 16 is cut at an angle of approximately 45° relative to the original side surface of the plate-shaped first workpiece 12.

[0216] In the same manner, the second abutment surface 18 is cut at an angle of approximately 45° relative to the original side surface of the plate-shaped second workpiece 14.

[0217] Therefore, with the first abutting surface 16 and the second abutting surface 18 in contact with each other, the first workpiece 12 and the second workpiece 14 are positioned at an angle of approximately 90° relative to each other.

[0218] As before, the first connecting groove 20 is provided on the first workpiece 12. However, the first connecting groove now extends vertically from the first abutment surface 16, and is therefore inclined overall relative to the first workpiece 12.

[0219] The same applies to the second connecting groove 36 provided on the second workpiece 14. The second connecting groove 36 also extends vertically from the second abutment surface 18, and is therefore inclined overall relative to the second workpiece 14.

[0220] Regarding the design of the first connecting groove 20 and the second connecting groove 36, refer to the explanation above.

[0221] Since the connecting grooves 20 and 36 are inclined relative to the associated workpieces 12 and 14, the entry channel 52 extending from the outer surface 54 of the second workpiece 14 is also inclined relative to the outer surface 54.

[0222] In component 10 according to the second embodiment, connector 56 is designed according to the second embodiment (see especially...). Figures 10 to 12 ).

[0223] Similarly, regarding the connector 56 according to the second embodiment, only references to the coupling will be made. Figures 1 to 7 The differences in the connectors are explained. Otherwise, the above explanation applies with the necessary modifications.

[0224] The first difference involves that the actuating body 86 is now rotatably supported on the second engaging element 80 and the fourth engaging element 84. Therefore, the connector 56 does not include a support opening for rotatably supporting the actuating body 86 on the carrier 58. In other words, the second engaging element 80 and the fourth engaging element 84 now include support openings for rotatably supporting the actuating body 86.

[0225] Since the actuating body 86 is now rotatably supported on the second engagement element 80 and the fourth engagement element 84, when the actuating body 86 rotates to move the connector 56 from the connected state to the released state, the actuating body 86 also translates linearly with the second engagement element 80 and the fourth engagement element 84, and vice versa.

[0226] In addition, the first actuator arm 88 and the second actuator arm 90 are now set at an angle of approximately 60°.

[0227] Furthermore, the first actuating arm 88 and the second actuating arm 90 are connected by a disc-segment-shaped connecting element 124. This enhances the stability of the actuating body 86. For example... Figure 12 In the embodiment shown, the first actuating arm 88 and the second actuating arm 90 are integrally formed with the disc segment-shaped element.

[0228] Another difference involves that the first abutment portion 118 is disposed on the head 88a of the first actuating arm 88, that is, at the free end of the first actuating arm 88.

[0229] Additionally, a recess is formed on each of the second engaging element 80 and the fourth engaging element 84 for receiving a portion of the first abutment portion 118 and / or the head 88a of the first actuating arm 88 when the connector 56 is in the released state. In the example shown, the recess is formed on the portion of the engaging elements 80, 84 adjacent to the connection section 70 of the carrier 56. In other words, the recess is formed at the ends of the second engaging element 80 and the fourth engaging element 84 facing the connection section 70. Furthermore, the recess is formed on the corresponding side of the first wall element 60 of the engaging elements 80, 84 facing the carrier 56.

[0230] The second abutting portion 120 is disposed on the head 90a of the second actuating arm 90, that is, at the free end of the second actuating arm 90.

[0231] Additionally, a recess is formed on each of the first engaging element 78 and the third engaging element 82 for receiving the second abutment portion 120 when the connector 56 is in the released state. In this example, the recess is formed on the outer surface of the engaging elements 78 and 82 and on the rear side of the engaging elements 78 and 82, i.e., on the side facing the rotation axis A.

[0232] Therefore, when the connector 56 according to the second embodiment is in the released state, the first engagement element 78 and the third engagement element 82 are supported on the head 90a of the second actuating arm 90, and the second engagement element 80 and the fourth engagement element 84 are supported on the head 88a of the first actuating arm 88.

[0233] The first actuating arm 88 and the second actuating arm 90 extend radially such that the angle between the first actuating arm 88 and the second actuating arm 90 relative to the axis of rotation A is greater than 45 degrees and less than 180 degrees, particularly less than 90 degrees. Figure 11 and Figure 12 In the example shown, the angle between the first actuator arm 88 and the second actuator arm 90 is approximately 75 degrees.

[0234] Furthermore, the connector 56 according to the second embodiment does not include any retaining portion. However, it is also conceivable that the connector 56 according to the second embodiment includes a retaining portion similar to that of the first embodiment.

[0235] Figures 13 to 24 A connector 56 according to a third embodiment is shown.

[0236] The connector 56 according to the third embodiment can be considered a variation of the connector 56 according to the first embodiment. Therefore, the differences from the connector 56 according to the first embodiment described above will only be explained below. Otherwise, the above explanation applies with necessary modifications. This specifically means that the connector 56 according to the third embodiment can be used to connect the first workpiece 12 and the second workpiece 14 in the same manner as explained with the connectors 56 according to the first and second embodiments. In other words, the connector 56 according to the third embodiment can form part of the assembly 10 in the same manner as the connector 56 according to the first embodiment.

[0237] The first difference in the connector 56 according to the third embodiment involves the first engagement element 78 including a locking element 128 (see in particular). Figure 19 and Figure 23 ).

[0238] In this example, the locking element 128 is formed as a pin or stud extending from the first engaging element 78 toward the second engaging element 80 and the fourth engaging element 84. This means that the locking element 128 extends along the insertion direction D and length L1 of the connector 56.

[0239] The locking element 128 is integrally formed with the remainder of the first engaging element 78. Furthermore, in this example, the locking element 128 has a substantially rectangular cross-section.

[0240] The length of the locking element 128 (i.e., the amount of extension of the locking element 128 along the length direction of the connector 56) is selected such that, in the released state of the connector 56, the locking element 128 (more precisely, the free end of the locking element 128) is positioned adjacent to the second engagement element 80 along the insertion direction D and length L1 of the connector 56.

[0241] Furthermore, the length of the locking element 128 is selected such that, in the connected state of the connector 56, the free end of the locking element 128 lies between the second engaging element 80 and the fourth engaging element 84 along the thickness L3 of the connector 56. In this position, the locking element 128 prevents or restricts the movement of the second engaging element 80 and the fourth engaging element 84 toward each other. Additionally, the locking element 128 prevents deformation of the second engaging element 80 and the fourth engaging element 84 toward each other.

[0242] Similar to the first engaging element 78, the third engaging element 82 also includes a locking element 130 (see in detail). Figure 14 , Figure 18 , Figure 21 and Figure 23 .

[0243] In this example, the locking element 130 is formed as a pin or stud extending from the third engaging element 82 toward the second engaging element 80 and the fourth engaging element 84. This means that the locking element 130 extends along the insertion direction D and length L1 of the connector 56.

[0244] The locking element 130 is integrally formed with the remainder of the third engaging element 82. Furthermore, in this example, the locking element 130 has a substantially rectangular cross-section.

[0245] The length of the locking element 130 (i.e., the amount of extension of the locking element 130 along the length direction of the connector 56) is selected such that, in the released state of the connector 56, the locking element 130 (more precisely, the free end of the locking element 130) is positioned adjacent to the fourth engagement element 84 along the insertion direction D and length L1 of the connector 56.

[0246] Furthermore, the length of the locking element 130 is selected such that, in the connected state of the connector 56, the free end of the locking element 130 lies between the second engaging element 80 and the fourth engaging element 84 along the thickness L3 of the connector 56. In this position, the locking element 128 prevents the second engaging element 80 and the fourth engaging element 84 from moving toward each other. Additionally, the locking element 128 prevents the second engaging element 80 and the fourth engaging element 84 from deforming toward each other.

[0247] In summary, when connector 56 is in the connected state, considering the direction of extension parallel to the thickness L3 of connector 56, the second engagement element 80 and the fourth engagement element 84 are supported on each other by the locking element 128 of the first engagement element 78, the locking element 130 of the third engagement element 82, and the head 90a of the second actuating arm 90. This not only prevents the second engagement element 80 and the fourth engagement element 84 from moving toward each other, but also prevents undesirable plastic or elastic deformation of the second engagement element 80 and the fourth engagement element 84.

[0248] Note that locking elements 128 and 130 essentially perform the same function as retaining portion 122. The difference is that, in this example, when connector 56 is in the connected state, locking elements 128 and 130 lock or prevent movement of the second engaging element 80 and the fourth engaging element 84. Therefore, due to locking elements 128 and 130, undesirable movement and / or undesirable deformation of the second engaging element 80 and the fourth engaging element 84 relative to the carrier 58 are impossible. Therefore, locking elements 128 and 130 can also be designated as retaining portions, although they are disposed on the first engaging element 78 and the third engaging element 82, respectively, instead of on the carrier 58.

[0249] Another difference in the connector 56 according to the third embodiment involves that the first engagement element 78 includes a first retaining device 132 configured to secure the first engagement element 78 against the third engagement element 82 in the connected state of the connector 56. More specifically, the third engagement element 82 also includes a third retaining device 134. The first retaining device 132 and the third retaining device 134 are configured to engage with each other in the connected state of the connector 56 (see in particular). Figure 14 , Figure 15 , Figure 18 , Figure 19 and Figure 23 Therefore, the first fixing device 132 and the third fixing device 134 can also be designated as interlocking devices or interlocking structures.

[0250] In this example, the first fixing device 132 includes two hooks 132a and 132b. The third fixing device 134 includes two openings 134a and 134b. Hook 132a extends through opening 134a, and hook 132b extends through opening 134b, wherein hooks 132a and 132b and openings 134a and 134b are shaped such that when the connector 56 is in the connected state, each of hooks 132a and 132b abuts against the edge of the associated opening 134a and 134b, thereby preventing further movement of the first engaging element 78 and the third engaging element 82 away from each other, but allowing the first engaging element 78 and the third engaging element 82 to move toward each other.

[0251] More generally, the first fixing device 132 of the first engaging element 78 extends at least partially through the third engaging element 82, or more precisely through the third fixing device 134 of the third engaging element 82.

[0252] In the connected state of connector 56, the first fixing device 132 and the third fixing device 134 prevent undesirable plastic or elastic deformation of the first engaging element 78 and the third engaging element 82. Furthermore, the first fixing device 132 and the third fixing device 134 serve as torque supports for the torque generated by the engagement of the workpiece through the first engaging element 78 and the third engaging element 82, and the torque generated by the interaction between the first actuating arm 88 and the first engaging element 78 and the third engaging element 82.

[0253] Furthermore, the surface 132c on the hook 132a of the first fixing device 132 serves as the abutment surface of the head 88a of the first actuating arm 88 when the connector 56 is engaged. By abutting the head 88a against the surface 132, the head 88a is in a meaningful position. In particular, the surface 132c prevents the head 88a from moving too far.

[0254] Furthermore, the second engaging element 80 includes a second retaining device 136 configured to secure the second engaging element 80 against the fourth engaging element 84 when the connector 56 is in the connected state. More specifically, the fourth engaging element 84 also includes a fourth retaining device 138. The second retaining device 136 and the fourth retaining device 138 are configured to engage with each other when the connector 56 is in the connected state (see in particular). Figure 15 , Figure 19 , Figure 20 and Figure 22 Therefore, the second fixing device 136 and the fourth fixing device 138 can also be designated as interlocking devices or interlocking structures.

[0255] In this example, the second fixing device 136 includes two hooks 136a and 136b. The fourth fixing device 138 also includes two hooks 138a and 138b. When the connector 56 is in the connected state, hook 136a engages hook 138a and hook 136b engages hook 138b. Furthermore, hooks 136a and 138a are shaped such that when the connector 56 is in the connected state, hooks 136a and 138a abut against each other, thereby preventing further movement of the second engaging element 80 and the fourth engaging element 84 away from each other, but allowing movement of the second engaging element 80 and the fourth engaging element 84 toward each other. Similarly, hooks 136b and 138b are shaped such that when the connector 56 is in the connected state, hooks 136b and 138b abut against each other, thereby preventing further movement of the second engaging element 80 and the fourth engaging element 84 away from each other, but allowing movement of the second engaging element 80 and the fourth engaging element 84 toward each other.

[0256] In the connected state of connector 56, the second fixing device 136 and the fourth fixing device 138 prevent undesirable deformation of the second engaging element 80 and the fourth engaging element 84. Furthermore, the second fixing device 136 and the fourth fixing device 138 serve as torque supports for the torque generated by the engagement of the workpiece through the second engaging element 80 and the fourth engaging element 84, and the interaction between the second actuating arm 90 and the second engaging element 80 and the fourth engaging element 84.

[0257] To allow movement of the hooks 136a and 136b of the second fixing device 136 and the hooks 138a and 138b of the fourth fixing device 138, a total of four recesses 140 are provided on the carrier 58 at positions adjacent to the corresponding hooks 136a, 136b, 138a, and 138b. This allows the connector 56 to be constructed in a compact manner.

[0258] Note that the designation of the fixing devices as first, second, third, and fourth is for ease of explanation only. The terms first, second, third, and fourth do not imply any number of fixing devices.

[0259] As explained above, connector 56 combines the advantages of providing a reliable connection between workpieces with the advantage of being constructed for easy removal from the connected workpieces when needed. In other words, connector 56 has the advantage of being able to selectively transition from a connected state to a released state. During this transition, the first engaging element 78 and the third engaging element 82 need to move toward each other. Similarly, the second engaging element 80 and the fourth engaging element 84 need to move toward each other.

[0260] This movement is achieved by appropriately rotating the actuating body 86.

[0261] Furthermore, in the third example, two first guide surfaces 142a and 142b are provided for guiding the movement of the first engaging element 78 from a position associated with its connection state with the connector 56 to a position associated with its release state with the connector 56, and vice versa. Thus, one of the first guide surfaces 142a and 142b is located at one end of the guide rail 96, and the other of the first guide surfaces 142a and 142b is located at one end of the guide rail 98; that is, both first guide surfaces 142a and 142b are located on the carrier 58 (see, in particular). Figure 18 , Figure 19 and Figure 24 Both first guide surfaces 142a and 142b are inclined such that when moving from a position associated with the connected state of connector 56 to a position associated with the released state of connector 56, the first engagement element 78 moves toward or is permitted to move toward the third engagement element 82.

[0262] Furthermore, both first guide surfaces 142a and 142b are inclined such that when moving from a position associated with the released state of connector 56 to a position associated with the connected state of connector 56, the first engagement element 78 moves away from the third engagement element 82 and / or is allowed to move away from the third engagement element 82.

[0263] To allow for a meaningful and smooth engagement with the first guide surfaces 142a, 142b, the first engagement element 78 includes two protrusions 143a, 143b disposed at its opposite ends, wherein protrusion 143a is configured to interact with guide surface 142a, and wherein protrusion 143b is configured to interact with guide surface 142b. The surfaces of protrusions 143a, 143b that contact guide surfaces 142a, 142b are correspondingly inclined to guide surfaces 142a, 142b.

[0264] In the third example, two second guide surfaces 144a and 144b are provided to guide the movement of the second engaging element 80 from a position associated with its connection state with the connector 56 to a position associated with its release state with the connector 56, and vice versa. Thus, one of the second guide surfaces 144a and 144b is located at one end of the guide rail 96, and the other is located at one end of the guide rail 98; that is, both second guide surfaces 144a and 144b are located on the carrier 58 (see, in particular). Figure 24 Both second guide surfaces 144a and 144b are inclined such that when moving from a position associated with the connected state of connector 56 to a position associated with the released state of connector 56, the second engagement element 80 moves toward or is permitted to move toward the fourth engagement element 84.

[0265] Furthermore, both second guide surfaces 144a and 144b are inclined such that when moving from a position associated with the released state of connector 56 to a position associated with the connected state of connector 56, the second engagement element 80 moves away from the fourth engagement element 84 or is allowed to move away from the fourth engagement element 84.

[0266] To allow for a meaningful and smooth engagement with the second guide surfaces 144a, 144b, the second engagement element 80 includes two protrusions 145a, 145b disposed at its opposite ends, wherein protrusion 145a is configured to interact with guide surface 144a, and wherein protrusion 145b is configured to interact with guide surface 144b. The surfaces of protrusions 145a, 145b that contact guide surfaces 144a, 144b are correspondingly inclined to guide surfaces 144a, 144b.

[0267] Furthermore, in the third example, two third guide surfaces 146a and 146b are provided for guiding the movement of the third engaging element 82 from a position associated with its connection state with the connector 56 to a position associated with its release state with the connector 56, and vice versa. Thus, one of the third guide surfaces 146a and 146b is located at one end of the guide rail 96, and the other is located at one end of the guide rail 98; that is, both third guide surfaces 146a and 146b are located on the carrier 58 (see, in particular). Figure 18 , Figure 19 and Figure 24 Both third guide surfaces 146a and 146b are inclined such that when moving from a position associated with the connected state of connector 56 to a position associated with the released state of connector 56, the third engagement element 82 moves toward or is permitted to move toward the first engagement element 78.

[0268] Furthermore, both third guide surfaces 146a and 146b are inclined such that when moving from a position associated with the released state of connector 56 to a position associated with the connected state of connector 56, the third engagement element 82 moves toward or is permitted to move toward the fourth engagement element 84.

[0269] To allow for a meaningful and smooth engagement with the third guide surfaces 146a, 146b, the third engagement element 82 includes two protrusions 147a, 147b disposed at its opposite ends, wherein protrusion 147a is configured to interact with guide surface 146a, and wherein protrusion 147b is configured to interact with guide surface 146b. The surfaces of protrusions 147a, 147b that contact guide surfaces 146a, 146b are correspondingly inclined to guide surfaces 146a, 146b.

[0270] Furthermore, in the third example, two fourth guide surfaces 148a and 148b are provided for guiding the movement of the fourth engaging element 84 from a position associated with its connection state with the connector 56 to a position associated with its release state with the connector 56, and vice versa. Thus, one of the fourth guide surfaces 148a and 148b is located at one end of the guide rail 96, and the other is located at one end of the guide rail 98; that is, both fourth guide surfaces 148a and 148b are located on the carrier 58 (see, in particular). Figure 24Both fourth guide surfaces 148a and 148b are inclined such that when moving from a position associated with the connected state of connector 56 to a position associated with the released state of connector 56, the fourth engagement element 84 moves toward or is permitted to move toward the second engagement element 80.

[0271] Furthermore, both fourth guide surfaces 148a and 148b are inclined such that when moving from a position associated with the released state of connector 56 to a position associated with the connected state of connector 56, the fourth engagement element 84 moves toward the third engagement element 82 and away from the second engagement element 80.

[0272] To allow for a meaningful and smooth engagement with the fourth guide surfaces 148a, 148b, the fourth engagement element 84 includes two protrusions 149a, 149b disposed at its opposite ends, wherein protrusion 149a is configured to interact with guide surface 148a, and wherein protrusion 149b is configured to interact with guide surface 148b. The surfaces of protrusions 149a, 149b that contact guide surfaces 148a, 148b are correspondingly inclined to guide surfaces 148a, 148b.

[0273] The substantially the same differences that have been explained with respect to the structural features of the connector 56 according to the third embodiment apply to the method of operating the connector 56 according to the third embodiment.

[0274] This means that when operating the connector 56 according to the third example, when the connector 56 is in the connected state or moved to the connected state, the locking elements 128 and 130 can be used to lock the second engagement element 80 and the fourth engagement element 84.

[0275] Similarly, when the connector is in the released state or moved to the released state, the movement of the second engagement element 80 and the fourth engagement element 84 can be achieved by withdrawing the locking elements 128 and 130.

[0276] Furthermore, when operating the connector 56 according to the third embodiment, the first engaging element 78 and the third engaging element 82 can be fixed to each other using the first fixing device 132 and the third fixing device 134 when the connector 56 is in the connected state or moved to the connected state. In other words, when the connector 56 is in the connected state, the first engaging element 78 and the third engaging element 82 can interlock.

[0277] Similarly, when connector 56 is in the connected state or moved to the connected state, the second engaging element 80 and the fourth engaging element 84 can be secured to each other using the second fixing device 136 and the fourth fixing device 138. In other words, when connector 56 is in the connected state, the second engaging element 80 and the fourth engaging element 84 can interlock.

[0278] Furthermore, as explained above, when moving from a position associated with the connected state of connector 56 to a position associated with the released state of connector 56, the first engagement element 78 can be guided by the first guide surfaces 142a, 142b. Therefore, when connector 56 is in the released state, the first engagement element 78 can interlock with the carrier 58 to present a defined position that allows connector 56 to be withdrawn from the first engagement groove 20, which includes the first undercut 26 of the first workpiece 12.

[0279] Furthermore, when moving from a position associated with the connected state of connector 56 to a position associated with the released state of connector 56, the second engagement element 80 can be guided by the second guide surfaces 144a, 144b. Therefore, when connector 56 is in the released state, the second engagement element 80 can interlock with the carrier 58 to present a defined position that allows connector 56 to be withdrawn from the second engagement groove 36, which includes the second undercut 42 of the second workpiece 14.

[0280] Furthermore, when moving from a position associated with the connected state of connector 56 to a position associated with the released state of connector 56, the third engagement element 82 can be guided by the third guide surfaces 146a, 146b. Therefore, when connector 56 is in the released state, the third engagement element 82 can interlock with the carrier 58 to present a defined position that allows connector 56 to be withdrawn from the first engagement groove 20 including the third undercut 32 of the first workpiece 12.

[0281] Additionally, the fourth engagement element 84 can be guided by the fourth guide surfaces 148a, 148b when moving from a position associated with the connected state of connector 56 to both a position associated with the released state and a position associated with the connected state of connector 56. Therefore, when connector 56 is in the released state, the fourth engagement element 84 can interlock with the carrier 58 to present a defined position that allows connector 56 to be withdrawn from the second engagement groove 36, which includes the fourth undercut 48 of the second workpiece 14.

[0282] When moving between a position associated with the released state of connector 56 and a position associated with the connected state of connector 56, each engagement element 78, 80, 82, 84 (more specifically, its protrusions 143a, 143b, 145a, 145b, 147a, 147b, 149a, 149b) is guided by associated guide surfaces 142a, 142b, 144a, 144b, 146a, 146b, 148a, 148b. When in the position associated with the connected state of connector 56, the first engagement element 78 and the third engagement element 82 can be held by the retaining portion 122.

[0283] This is Figure 25 As schematically shown in a), the positions of the engagement elements 78, 80, 82, 84 (more precisely, their protrusions 143a, 143b, 145a, 145b, 147a, 147b, 149a, 149b) associated with the connected state of connector 56 are marked with C, and the positions of the engagement elements 78, 80, 82, 84 (more precisely, their protrusions 143a, 143b, 145a, 145b, 147a, 147b, 149a, 149b) associated with the released state of connector 56 are marked with R. The movement of each engagement element 78, 80, 82, 84 is shown with dashed arrows.

[0284] This configuration ensures that all engagement elements 78, 80, 82, and 84 are positioned in the desired positions associated with the connected and released states of connector 56, and that engagement elements 78, 80, 82, and 84 reliably transition between these positions.

[0285] It should be noted that the guide grooves 150, 152, 154, 156 can achieve the same function for each engagement element 78, 80, 82, 84, wherein each protrusion 143a, 143b, 145a, 145b, 147a, 147b, 149a, 149b of the engagement elements 78, 80, 82, 84 is at least partially received in the associated guide groove 150, 152, 154, 156, wherein the guide grooves 150, 152, 154, 156 are arranged in the guide rail 98.

[0286] More precisely, the protrusion 143b of the first engaging element 78 is received in the guide groove 150, the protrusion 145b of the second engaging element 80 is received in the guide groove 152, the protrusion 147b of the third engaging element 82 is received in the guide groove 154, and the protrusion 149b of the fourth engaging element 84 is received in the guide groove 156.

[0287] This alternative is in Figure 25 As shown in b).

[0288] This also applies to protrusions 143a, 145a, 147a, and 149a that are arranged to mate with guide rail 96.

[0289] Note that in Figure 25 In alternative b), protrusions 143a, 143b, 145a, 145b, 147a, 147b, 149a, and 149b may have the same shape as in the aforementioned examples. However, protrusions 143a, 143b, 145a, 145b, 147a, 147b, 149a, and 149b may also have a circular cross-section.
