[0237] Identical or functionally equivalent elements are provided with the same reference symbols in all figures.

[0238] A connecting element designated as a whole by 100 serves, for example, to connect a first, essentially plate-shaped component 102 with a second, also essentially plate-shaped component 104 (see Fig. 1 to 4).

[0239] The two components 102 and 104 are made of wood or plywood, for example, but can also be made of any other material, such as a metallic material or a plastic material (e.g., Plexiglas). Furthermore, it is possible for the first component 102 and the second component 104 to be made of different materials.

[0240] In the connected state of the two components 102 and 104, a contact surface 106 of the first component 102, forming a narrow side of the first component 102, lies against a contact surface 108 of the second component 104, forming a main surface of the second component 104.

[0241] Each of the contact surfaces 106, 108 opens into a groove 110 formed in the respective component 102 or 104, which comprises a circular cylinder segment or circular cylinder section-shaped base section 112 and two undercut sections 114 extending away from the base section 112 in a thickness direction 116.

[0242] The radius of curvature of the base section 112 is larger than the groove depth T (see Fig. 4), so that the curved groove base surface 118 intersects the respective contact surface 106, 108 at an acute angle.

[0243] The base section 112 of the groove 110 has a width B of, for example, approximately 8 mm in the thickness direction 116.

[0244] Each of the undercut sections 114 of the groove 110 is bounded on its side facing away from the respective contact surface 106 or 108 by a base surface 120 flush with the groove base surface 118, which is formed in the shape of a circular cylindrical shell section and has the same radius of curvature as the groove base surface 118 of the base section 112.

[0245] In the direction towards the contact surface 106 or 108, each undercut section 114 is bounded by an undercut surface 122 which is also shaped like a circular cylindrical shell section and which is concentric to the base surface 120 and has a smaller radius of curvature.

[0246] Each of the undercut sections 114 is laterally bounded by a lateral boundary surface 124 running perpendicular to the respective contact surface 106 or 108.

[0247] The width b, that is, the extent in the thickness direction 116, is approximately 1 mm for each of the undercut sections 114, for example.

[0248] The height h, that is, the distance between the base surface 120 and the undercut surface 122, is approximately 2 mm for each of the undercut sections 114, for example.

[0249] The base section 112 of each groove 110 is bounded by lateral boundary walls 126 which run essentially perpendicular to the respective contact surface 106 or 108 and which have a distance from each other of the groove width B.

[0250] For example, from Fig. As can be seen in Figure 3, a substantially cylindrical access opening 128, in particular an access bore, opens into the groove 110 of the first component 102, running perpendicular to one of the lateral boundary walls 126, the other end of which opens onto a main surface 129 of the first component 102 and thus enables access from the outside of the first component 102 to the base section 112 of the groove 110.

[0251] To form the grooves 110 described above on components 102 and 104, the slot milling device described in EP 1 990 549 A1 can be used, for example.

[0252] To connect the components 102, 104 to each other, one or more grooves 110, in particular grooves 110 of the type described above, can be provided in each of the components 102, 104.

[0253] However, it may also be provided that only one of the components 102, 104 is provided with one or more grooves 110, in particular grooves 110 of the type mentioned above, while the other component 104, 102 does not include a groove 110 of the type described above, a differently designed groove 110, one or more bores, one or more recesses, one or more projections and / or one or more recesses, or is unmachined.

[0254] Various embodiments of connecting means 100 for connecting different components 102, 104, in particular differently prepared components 102, 104, are described below.

[0255] In the Fig. Figures 5 to 9 show a first embodiment of a connecting element 100, which comprises a connecting element 130 that can be inserted into a groove 110 and a connecting element 130 designed as a screw element 132.

[0256] A connecting element 130 that can be inserted into a groove 110 is preferably understood to be a connecting element 130 which can be inserted into a groove 110 comprising a base section 112 and one or more undercut sections 114 extending away from the base section 112 in a thickness direction 116. The one or more undercut sections 114 preferably have one or more undercut surfaces 122 which are formed and arranged concentrically to the base section 112. The undercut surface or surfaces 122 are in particular formed in the shape of a circular cylindrical section.

[0257] A connecting element 130 that can be inserted into a groove 110 preferably comprises a base body 134, which includes a base part 136 corresponding to the base section 112 of the groove 110 and one or more retaining projections 138 corresponding to the undercut sections 114.

[0258] The retaining projections 138 each comprise a curved support surface 140, which is arc-shaped in a longitudinal section.

[0259] The retaining projections 138 are specifically designed to be non-self-tapping.

[0260] In this description and the attached claims, a longitudinal section, a longitudinal direction, etc., shall be understood to mean a section or a movement of the connecting element 130 in a plane in which a movement path of the connecting element 130 lies when it is inserted into a groove 110.

[0261] A longitudinal section is in particular a section taken perpendicular to an axis of symmetry of the support surfaces 140 of the connecting element 130.

[0262] A cross-section is understood in particular to be a section taken perpendicular to a longitudinal section, for example a section taken perpendicular to a contact surface 106, 108 and parallel to the axis of symmetry of the support surfaces 140 of the connecting element 130.

[0263] Preferably, a cross-section is a section along a plane in which the axis of symmetry of the support surfaces 140 of the connecting element 130 runs.

[0264] During the Fig. In the first embodiment of the connecting element 100 shown in Figures 5 to 9, the connecting element 130, which can be inserted into a groove 110, comprises a retaining element 142 arranged on the base body 134, in particular rotatably mounted on the same.

[0265] The retaining element 142 is arranged rotatably on the base body 134, in particular about an axis of rotation 144 running parallel to the thickness direction 116.

[0266] How in particular Fig. As can be seen from Figure 8, the retaining element 142 comprises two engagement projections 146, which are arc-shaped and arranged eccentrically to the axis of rotation 144.

[0267] By means of the engagement projections 146, in particular an engagement section 148 of the connecting element 130 designed as a screw element 132 can be grasped and pulled in the direction of the axis of rotation 144.

[0268] The connecting element 130, designed as a screw element 132, includes in addition to the engagement section 148 a stop 150.

[0269] By means of the stop 150, the screw element 132 can be reliably fixed in a correct position on one of the components 102, 104.

[0270] In particular, the stop 150 ensures that the engagement section 148, when the screw element 132 is mounted on one of the components 102, 104, protrudes sufficiently far beyond a contact surface 106, 108 of the component 102, 104 in order to engage with the retaining element 142.

[0271] In the assembled state of the connecting element 130, which can be inserted into the groove 110, the contact surfaces 106, 108 of the component 102, 104 and a bearing surface 152 of the connecting element 130 are preferably essentially flush with the surface.

[0272] The connecting element 130 is preferably screwable to the component 102, 104 on which the groove 110 is arranged. The base body 134 of the connecting element 130 comprises two through-openings 154 for the passage of screws (not shown). The through-openings 154 are also provided with recesses 156 so that screw heads (not shown) can be received within an outer contour of the base body 134.

[0273] The connection between components 102 and 104 using the connecting element 100 is established as follows: First, the connecting element 130, designed as a screw element 132, is screwed into one of the components 102, 104 until the stop 150 of the screw element 132 rests against the contact surface 106, 108.

[0274] The further component 104, 102 is then connected with a groove 110, in particular with one of the ones in the Fig. 1 to 4 of the depicted grooves 110, provided.

[0275] The connecting element 130, which can be inserted into the groove 110, is then inserted into the groove 110 and fixed to the component 102, 104 by means of the (not shown) screws.

[0276] Through a cylindrical access bore 128 previously introduced into the component 102, 104, the retaining element 142 is accessible in the assembled state of the connecting element 130, which can be inserted into the groove 110.

[0277] In a next step, the components 102, 104 are placed next to each other in such a way that the engagement section 148 of the screw element 132 enters a corresponding receiving opening 158 in the base body 134 of the connecting element 130.

[0278] Components 102 and 104 then lie against each other with their contact surfaces 106 and 108.

[0279] To fix the components 102, 104 relative to each other, the retaining element 142 only needs to be moved from the initially set release position into a holding position.

[0280] A wrench (not shown) is inserted through the access bore 128 and engaged with a wrench socket 160 of the retaining element 142. By rotating the wrench, and thus also the retaining element 142, around the axis of rotation 144, the retaining element 142 is moved from the release position to the holding position.

[0281] The engagement projections 146 engage behind the engagement section 148 of the screw element 132 and pull it in the direction of the axis of rotation 144.

[0282] This exerts a tensile force on components 102 and 104, so that they are firmly connected to each other.

[0283] The connecting element 130, designed as a screw element 132, preferably has a substantially rotationally symmetrical engagement section 148. In this way, the screw element 132 can always be reliably gripped by means of the retaining element 142, regardless of its rotational orientation.

[0284] The anchoring of the connecting element 130, which includes the engagement section 148, can be achieved, on the one hand, by means of the screw shown. Alternatively, however, a bolt-like press-fit, gluing, screwing in using a Spax thread or a metric thread, fixing with a dowel, riveting and / or welding of an element having the engagement section 148 to the one component 102, 104 can also be provided.

[0285] One in the Fig. The second embodiment of a connecting element 100, as illustrated in Figures 10 to 15, differs from the one shown in the Fig. The first embodiment shown in Figures 5 to 9 is essentially distinguished by the fact that, in addition to a connecting element 130 that can be inserted into a groove 110, a connecting element 130 that is essentially cuboid in shape is provided.

[0286] This cuboid connecting element 130 can be screwed onto a contact surface 108 of a component 104, in particular by means of two screws 162.

[0287] The cuboid connecting element 130 comprises two engagement projections 146 and an essentially semi-ring-shaped engagement channel 164.

[0288] The connecting element 130, which can be inserted into the groove 110, comprises a retaining element 142, which at least in sections has a substantially T-shaped cross-section and thus includes an engagement section 148.

[0289] The retaining element 142 can be inserted into the engagement channel 164 of the cuboid connecting element 130, in particular by a rotary movement, and can be brought into engagement with the engagement projections 146.

[0290] The connecting element 130, which can be inserted into the groove 110, further comprises two insertion projections 166, which can be inserted into corresponding receiving pockets 168 in the cuboid connecting element 130.

[0291] The insertion projections 166 and the receiving pockets 168 preferably have a grooved or wavy surface to prevent the insertion projections 166 from shifting within the receiving pockets 168.

[0292] How especially the Fig. 11 and Fig. As can be seen from 14, the connecting element 130, which can be arranged in the groove 110, is preferably completely arranged in the groove 110.

[0293] In the assembled state of the connecting element 130, the contact surface 152 of the base body 134 of the connecting element 130 is set back in the groove 110 from the contact surface 106 of the component 102.

[0294] In the connected state of components 102, 104, their contact surfaces 106, 108 are in contact with each other.

[0295] The cuboid connecting element 130, which is screwed onto the contact surface 108 of the second component 104, then extends into the groove 110 in the first component 102.

[0296] By simply inserting the cuboid connecting element 130 into the groove 110 in the first component 102, a reliable fixing of the components 102, 104 relative to each other with respect to the thickness direction 116 can be achieved.

[0297] By rotating the retaining element 142 using the (not shown) wrench, the retaining element 142 can be brought into the holding position in which the engagement section 148 engages behind the engagement projections 146 and fixes the connecting elements 130 and the components 102, 104 with respect to a connection direction 170 oriented perpendicular to the contact surfaces 106, 108.

[0298] Moreover, the one in the Fig. The second embodiment of the connecting element 100, illustrated in 10 to 15, differs in structure and function from that shown in the Fig. The first embodiment shown in sections 5 to 9 is identical, so reference is made to its preceding description.

[0299] One in the Fig. 16 and Fig. The third embodiment of a connecting element 100, as shown in Figure 17, differs from the one shown in the Fig. The second embodiment shown in Figures 10 to 15 is essentially distinguished by the fact that, in addition to a connecting element 130 which can be inserted into the groove 110, a connecting element 130 designed as a screw element 132 is provided.

[0300] This screw element 132 can be screwed into one of the components 102, 104.

[0301] A cuboid section 172 of the screw element 132 comprises an engagement channel 164 and two engagement projections 146.

[0302] Similar to the one in the Fig. The second embodiment shown in Figures 10 to 15 is therefore also the same in the embodiment shown in the Fig. 16 and Fig. In the third embodiment shown in Figure 17, a connecting element 130 is provided which can be placed on a contact surface 106, 108 of a component 102, 104, in particular screwable, and into which a retaining element 142, which has a substantially T-shaped cross-section and thus comprises an engagement section 148, can be inserted.

[0303] Moreover, the one in the Fig. 16 and Fig. 17 third embodiment of the connecting element 100 with regard to structure and function with the one described in the Fig. The second embodiment shown in Figures 10 to 15 is identical, so reference is made to its preceding description.

[0304] One in the Fig. The fourth embodiment of a connecting element 100, as shown in Figures 18 to 22, differs from the one shown in the Fig. The first embodiment shown in Figures 5 to 9 is essentially distinguished by the fact that each of the components 102, 104 is assigned two connecting elements 130 that can be inserted into a groove 110.

[0305] The grooves 110 in each component 102, 104 are arranged in an overlapping manner, so that the groove base surfaces 118 of the grooves 110 within the respective component 102, 104 intersect or abut each other below the contact surface 106, 108.

[0306] During the Fig. In the fourth embodiment of the connecting element 100 shown in Figures 18 to 22, two types of connecting elements 130 are provided.

[0307] On the one hand, connecting elements 130 are provided, each comprising two hanging elements 174.

[0308] Furthermore, connecting elements 130 are provided, each comprising two suspension element receptacles 176.

[0309] Both the suspension elements 174 and the suspension element receptacles 176 each comprise at least one inclined surface 178, which is oriented at an angle to the mounting surface 152 and / or at an angle to the contact surface 106, 108.

[0310] Furthermore, all connecting elements 130 each include a securing projection 180 and a securing recess 182.

[0311] A locking device 184 is formed by means of the locking projection 180 and the locking recess 182. The locking device 184 serves in particular to secure at least one of the connecting elements 130 in the groove 110, especially to prevent unwanted displacement of the connecting element 130 within the groove 110.

[0312] For this purpose, a locking projection 180 of a connecting element 130 can be engaged with a locking recess 182 of another connecting element 130 (see in particular the Fig. 21 and Fig. 22).

[0313] A securing projection 180 and a securing recess 182 of a connecting element 130 are preferably arranged on opposite end regions 186 of the base body 134, in particular the support surfaces 140.

[0314] How in particular Fig. As can be seen from Figure 19, the connecting elements 130 each further comprise a passage opening 188, which is arranged on the respective connecting element 130 in such a way that the passage openings 188 of two connected connecting elements 130 are aligned with each other in the connected state of the components 102, 104.

[0315] By inserting a locking element, in particular a locking pin, into the passage openings 188, the connecting elements 130 and thus also the components 102, 104 can be secured against unwanted displacement relative to each other.

[0316] How in particular Fig. As can be seen from 19, the components 102 and 104 are connected by means of the connecting elements 130 during the process described in the Fig. In the fourth embodiment of the connecting element 100 shown in Figures 18 to 22, the connection is not made by rotating a retaining element 142. Rather, the components 102, 104 together with the connecting elements 130 arranged thereon are first moved towards each other in order to insert the suspension elements 174 into the suspension element receptacles 176 (see Figures 18 to 22). Fig. 18).

[0317] Subsequently, the components 102, 104 and the connecting elements 130 arranged therein are moved parallel to the contact surfaces 106, 108. The inclined surfaces 178 of the suspension elements 174 and the suspension element receptacles 176 thereby engage with each other, so that the connecting elements 130 and thus also the components 102, 104 are drawn towards each other.

[0318] The in the Fig. The fourth embodiment of the connecting element 100, shown in Figures 18 to 22, is particularly suitable for connecting frame components of a bed frame.

[0319] Moreover, the one in the Fig. The embodiment of a connecting element 100 shown in figures 18 to 22 is comparable in structure and function to that shown in the Fig. The first embodiment shown in sections 5 to 9 is identical, so reference is made to its preceding description.

[0320] One in the Fig. The fifth embodiment of a connecting element 100, illustrated in Figures 23 to 26, differs from the one shown in the Fig. The first embodiment shown in Figures 5 to 9 differs essentially in that two connecting elements 130 are provided which can each be inserted into a groove 110.

[0321] Furthermore, in the Fig. In the embodiment of the connecting element 100 shown in Figures 23 to 26, it is provided that a retaining element 142 can be actuated by means of a magnetic element 190 in order to bring the retaining element 142 from a release position to a holding position and / or from the holding position to the release position.

[0322] The magnetic element 190 is in particular an element that can be actuated magnetically with a (not shown) magnetic device.

[0323] The magnetic element 190 can be moved linearly back and forth, for example, by means of the magnetic device.

[0324] The retaining element 142 preferably comprises a receptacle 192 for the magnetic element 190.

[0325] One of the connecting elements 130 preferably serves to receive the retaining element 142 together with the magnetic element 190 received therein.

[0326] This connecting element 130 comprises in particular a substantially slot-like guide 194 in the base body 134.

[0327] The retaining element 142 is movable along the slot-like guide 194 relative to the base body 134.

[0328] The retaining element 142 further comprises two inclined surfaces 178 which can be engaged with engagement projections 146 in the further connecting element 130.

[0329] The inclined surfaces 178 of the retaining element 142 thus form an engagement section 148 of the retaining element 142.

[0330] How especially the Fig. 24 and Fig. As can be seen from 25, the connecting elements comprise 130 according to the one in the Fig. fifth embodiment of the connecting element 100 insertion projections 166 and receiving pockets 168 shown in Figures 23 to 26.

[0331] When connecting the connecting elements 130 to each other, the insertion projections 166 are first inserted into the receiving pockets 168.

[0332] The engagement section 148, in particular the inclined surfaces 178, is simultaneously brought behind the engagement projections 146 with respect to the connection direction 170.

[0333] Finally, the mounting surfaces 152 of the connecting elements 130 and the contact surfaces 106, 108 of the components 102, 104 come together to form the system.

[0334] In order to fix the connecting elements 130 and thus the components 102, 104 relative to each other along the connection direction 170, the magnetic element 190 is now actuated in a next step.

[0335] For this purpose, the magnetic device is brought close to the connecting element 100 and the magnetic element 190 is accelerated within the receptacle 192.

[0336] The magnetic element 190 is repeatedly accelerated within the receptacle 192 and decelerated by striking an end area of ​​the receptacle 192.

[0337] The recording 192 is bounded on the one hand by a locking surface 196 and on the other hand by an unlocking surface 198.

[0338] When the magnetic element 190 strikes the locking surface 196, the retaining element 142 is brought into the holding position, in which the engagement section 148 of the retaining element 142 engages behind the engagement projections 146.

[0339] By striking the magnetic element 190 against the release surface 198, the retaining element 142 is moved in the opposite direction and thus the engagement section 148 with the engagement projections 146 is disengaged.

[0340] The holding element 142 can therefore be selectively moved into the holding position or into the release position.

[0341] The insertion projections 166 and the receiving pockets 168 preferably prevent the magnetic element 190 from striking the locking surface 196 or the unlocking surface 198, causing a displacement of the base bodies 134 of the connecting elements 130 relative to each other.

[0342] The in the Fig. The fifth embodiment of the connecting element 100, illustrated in Figures 23 to 26, can offer the particular advantage that the components 102 and 104 can be connected to each other without any visual impairment. In particular, an access hole 128 can be dispensed with.

[0343] Moreover, the one in the Fig. The fifth embodiment of the connecting element 100, illustrated in figures 23 to 26, differs in structure and function from that shown in the Fig. The first embodiment shown in sections 5 to 9 is identical, so reference is made to its preceding description.

[0344] One in the Fig. 27 and Fig. The sixth embodiment of a connecting element 100 shown in Figure 28 differs from the one shown in the Fig. The fifth embodiment shown in 23 to 26 differs essentially in that the retaining element 142 is a helical retaining element 142.

[0345] The magnetic element 190 can be driven in a rotating manner by means of the magnetic device in order to actuate the holding element 142 in a targeted manner.

[0346] The retaining element 142 and the magnetic element 190 are arranged on a base body 134 of a connecting element 130 that can be inserted into a groove 110.

[0347] A further connecting element 130, which is preferably also insertable into a groove 110, preferably comprises a receptacle 200 for the helical retaining element 142.

[0348] The part numbered 200 is specifically a screw nut.

[0349] The receptacle 200 is preferably movably, in particular resiliently, arranged on a base body 134 of the further connecting element 130. In particular, two spring elements 202 are provided on the base body 134 for this purpose.

[0350] The base bodies 134 of the connecting elements 130 preferably each comprise a cover element 204, by means of which an interior space 206 of the respective base body 134 can be closed.

[0351] In particular, by removing the respective cover element 204, the receptacle 200, the magnetic element 190 and / or the screw-like retaining element 142 can be accessed and / or removed from the respective base body 134.

[0352] How in particular Fig. As can be seen from Figure 27, the connecting elements 130 preferably each comprise at least one projection 208, a corresponding recess 210 and / or at least one comb 212 and / or a corresponding groove 214 for aligning the connecting elements 130 relative to each other in all directions perpendicular to the connection direction 170.

[0353] Regarding the manner of actuation of the holding element 142 by means of the magnetic element 190 and regarding the actuation of the magnetic element 190 by means of the magnetic device, reference is made to WO 99 / 43961 A1, the contents of which are hereby incorporated into this description.

[0354] Moreover, the one in the Fig. 27 and Fig. 28 shows the sixth embodiment of the connecting element 100 with regard to structure and function compared to the one described in the Fig. The fifth embodiment shown in Figures 23 to 26 is identical, so reference is made to its preceding description.

[0355] One in the Fig. 29 and Fig. The seventh embodiment of a connecting element 100 shown in Figure 30 differs from the one shown in the Fig. The fifth embodiment shown in 23 to 26 differs essentially in that the connecting elements 130 can be connected to each other by means of spring elements 216.

[0356] The spring elements 216 can engage behind engagement projections 146 for this purpose.

[0357] The spring elements 216 and the engagement projections 146 are arranged on different connecting elements 130.

[0358] During the Fig. 29 and Fig. In the seventh embodiment of the connecting element 100 shown in Figure 30, a storage device 218 is provided by means of which the holding energy or holding force required to hold the connecting elements 130 can be stored.

[0359] The storage device 218 comprises two storage elements 220, which are formed in particular by the spring elements 216, and a blocking element 222.

[0360] The locking element 222 can be used to hold the spring elements 216 in a pre-tensioned position (see Fig. 29).

[0361] The holding energy and / or holding force required to hold the connecting elements 130 and thus the components 102, 104 together can be obtained by the Fig. 29 and Fig. 30, the embodiment of the connecting element 100 is applied and stored before the actual joining of the components 102, 104.

[0362] When connecting the connecting elements 130 arranged on the components 102, 104, the locking element 222 is preferably extended from the surface by means of at least one engagement projection 146. Fig. 29 shown blocking position in the in Fig. Release position shown in 30 has been brought into effect.

[0363] The spring elements 216 can then move towards each other and engage behind the engagement projections 146.

[0364] The in the Fig. 29 and Fig. The fastener 100 shown in section 30 is in particular a concealed, self-tensioning fastener 100.

[0365] The storage device 218 can preferably be loaded into the components 102, 104 before, during, or after the installation of the connecting elements 130. In particular, the locking element 222 can be loaded into the components 102, 104 at any time before they are connected. Fig. The blocking position shown in 29 can be brought into place.

[0366] Moreover, the one in the Fig. 29 and Fig. 30 shows the seventh embodiment of the connecting element 100 with regard to structure and function compared to the one described in the Fig. The fifth embodiment shown in Figures 23 to 26 is identical, so reference is made to its preceding description.

[0367] One in Fig.The eighth embodiment of a connecting element 100 shown in Figure 31 differs from the one shown in the Fig. 29 and Fig. 30 shown seventh embodiment essentially in that the spring element 216 does not directly engage an engagement projection 146, but actuates an engagement section 148 of a substantially linearly movable holding element 142.

[0368] Preferably, the following can also be used in the Fig. In the eighth embodiment of the connecting means 100 shown in Figure 31, the storage device 218 can be loaded by tensioning the spring element 216, for example by locking the retaining element 142 and / or the spring element 216 in a pre-tensioned position.

[0369] During and / or by connecting the components 102, 104 to each other, the stored force and / or energy is preferably released to fix the connecting elements 130 relative to each other, in particular by engaging the engagement projections 146 with the engagement section 148 of the retaining element 142.

[0370] Moreover, the in Fig. Figure 31 shows the eighth embodiment of the connecting element 100 with regard to structure and function compared to the one described in the Fig. 29 and Fig. 30 corresponds to the seventh embodiment shown, so reference is made to its preceding description.

[0371] One in the Fig. The ninth embodiment of a connecting element 100, illustrated in Figures 32 to 34, differs from the one shown in the Fig. The fifth embodiment of a connecting means 100 shown in Figures 23 to 26 differs essentially in that the connecting elements 130, which are connecting elements 130 that can be inserted into a groove 110, comprise a tongue and groove device 224.

[0372] The tongue-and-groove device 224 is formed in particular by a groove part 226 and a tongue part 228.

[0373] The groove part 226 and the spring part 228 are arranged and / or formed on different connecting elements 130.

[0374] How especially the Fig. 32 and Fig. As can be seen from Figure 33, the connecting elements 130, in particular the groove part 226 and the spring part 228, can be brought into engagement with each other by inserting and pivoting the connecting elements 130 and / or the components 102, 104 relative to each other.

[0375] The tongue-and-groove device 224 serves in particular for the adhesive-free anchoring of one component 102 to the other component 104.

[0376] The tongue and groove device 224 preferably functions similarly to the locking mechanism used for floor elements of a click parquet floor or click laminate floor.

[0377] The in the Fig. The ninth embodiment of a connecting means 100 shown in Figures 32 to 34 is particularly suitable for connecting drawer fronts to drawer boxes.

[0378] Moreover, the one in the Fig. The ninth embodiment of a connecting element 100, illustrated in 32 to 34, differs in structure and function from that shown in the Fig. The fifth embodiment shown in Figures 23 to 26 is identical, so reference is made to its preceding description.

[0379] One in the Fig. The tenth embodiment of a connecting element 100, illustrated in Figures 35 to 37, differs from the one shown in the Fig. The first embodiment shown in Figures 5 to 9 differs essentially in that a connecting element 130 is provided which can be inserted into a groove 110 and which comprises one or more screw receptacles 230.

[0380] In the screw receptacles 230, connecting elements 130 designed as screw elements 132 can be detachably fixed in a form-fitting and / or force-fitting manner.

The connecting element 130 is thus, in particular, fastened by means of a screw 162 (not shown) (see, for example, Figure 5 to 9). Fig. 13) can be determined on the first component 102.

[0382] The connecting elements 130, designed as screw elements 132, are used in the Fig. The tenth embodiment of the connecting element 100 shown in Figures 35 to 37 can be passed through the passage openings 232 in the second component 104.

[0383] The connecting element 130, which can be inserted into the groove 110, in particular the screw receptacles 230, are thus accessible from a side 234 of the second component 104 facing away from the first component 102.

[0384] The second component 104 can thus be clamped and / or clamped between the screw heads 236 of the screw elements 132 and the connecting element 130, which can be inserted into the groove 110, by screwing the screw elements 132 together.

[0385] The screw receptacles 230 are, for example, threaded holes or elongated holes with a nut thread. Alternatively, the screw receptacles 230 can be designed to be flexible receptacles for self-tapping screws.

[0386] Preferably, the screw receptacles 230 are designed as elongated holes for thread-cutting screws.

[0387] The in the Fig. The tenth embodiment of the connecting element 100 shown in Figures 35 to 37 is particularly suitable as a fastening anchor in thin-walled, pull-out-resistant materials, for example similar to a dowel for fixing screws.

[0388] Moreover, the one in the Fig. Figures 35 to 37 illustrate the tenth embodiment of a connecting element 100 with regard to structure and function compared to the one described in the Fig. The first embodiment shown in sections 5 to 9 is identical, so reference is made to its preceding description.

[0389] One in the Fig. 38 and Fig. The eleventh embodiment of a connecting element 100 shown in Figure 39 differs from the embodiments described above essentially in that the connecting element 100 also allows relative movement of the components 102, 104 relative to each other in the assembled and connected state of the components 102, 104 and the connecting element 100.

[0390] By means of the connecting element 100 a guide device 238 is formed, by means of which the components 102, 104 are guided and movable relative to each other.

[0391] The connecting element 100 comprises at least one connecting element 130, which is a connecting element 130 that can be inserted into a groove 110.

[0392] This connecting element 130 preferably comprises a guide element 240, for example a guide projection 242, which, in the assembled state of the connecting element 130, projects beyond the contact surface 152 of the base body 134 of the connecting element 130 and beyond the contact surface 106 of the component 102 in which the connecting element 130 is arranged.

[0393] The guide element 240, for example, is essentially cuboid in shape.

[0394] The further component 104 preferably comprises a guide groove 244 for receiving the guide element 240.

[0395] The guide groove 244 is, for example, integrated into a connecting element 130 or into the component 104 itself.

[0396] During the Fig. 38 and Fig. In the eleventh embodiment of the connecting element 100 shown in Figure 39, the guide groove 244 is formed in the component 104, in particular in the form of a substantially cuboid recess in the side of the component 104 on which the contact surface 108 is arranged.

[0397] How in particular Fig. As can be seen from Figure 39, in the assembled state of the connecting element 100 and the components 102, 104, an undesired lateral displacement of the components 102, 104 in a direction transverse to the longitudinal extension direction of the guide groove 244 can be prevented.

[0398] However, a displacement of the components 102, 104 relative to each other along the longitudinal direction of the guide groove 244 is possible.

[0399] The in the Fig. 38 and Fig. The eleventh embodiment of the connecting element 100 shown in Figure 39 is particularly suitable for use as a sliding door fitting, for example at a lower end of a sliding door.

[0400] Moreover, the one in the Fig. 38 and Fig. Figure 39 shows the eleventh embodiment of a connecting element 100 with regard to structure and function, for example, with the one described in the Fig. The fourth embodiment shown in Figures 18 to 22 is identical, so reference is made to its preceding description.

[0401] One in the Fig. 40 and Fig. The twelfth embodiment of a connecting element 100, as illustrated in Figure 41, differs from the one shown in the Fig. 38 and Fig. 39 shown in the eleventh embodiment, essentially in that the guide element 240 comprises one or more bearing elements 246 for the slidable mounting of the components 102, 104 relative to each other.

[0402] The bearing elements 246 are designed in particular as roller elements 248.

[0403] For example, two pairs of roller elements 248 are provided.

[0404] The guide groove 244 is located in the Fig. 40 and Fig. 41 shown twelfth embodiment of the connecting means 100 is formed by a connecting element 130 which is arranged in one of the components 102, 104.

[0405] The guide groove 244 preferably comprises a guide section 250, on which the guide element 240, in particular the bearing elements 246 of the guide element 240, can engage behind the guide groove 244.

[0406] The guide groove 244 is, for example, open downwards with respect to the direction of gravity g, so that the connecting element 130 comprising the guide element 240 together with the component 102 on which the connecting element 130 is arranged can be hooked into the guide groove 244.

[0407] Such a connecting element 100 can then be used in particular as a suspension for a sliding door.

[0408] Moreover, the one in the Fig. 40 and Fig. 41, the twelfth embodiment of a connecting element 100, is shown with regard to its structure and function, in relation to the one described in the Fig. 38 and Fig. 39 corresponds to the eleventh embodiment shown, so reference is made to its preceding description in this respect.

[0409] One in the Fig. 42 and Fig. The thirteenth embodiment of a connecting element 100, as illustrated in Figure 43, differs from the one shown in the Fig. 40 and Fig. 41 twelfth embodiment essentially in that a bearing element 246 designed as a roller element 248 is arranged on the base body 134 of the connecting element 130.

[0410] This connecting element 130 can also preferably be inserted into a groove 110.

[0411] The bearing element 246 preferably projects beyond the contact surface 152 of the base body 134 and beyond a contact surface 106 of the component 102 in which the connecting element 130 is arranged.

[0412] The bearing element 246, designed as a roller element 248, is in particular rotatably mounted on the base body 134 and can, for example, roll on a running surface 252.

[0413] The running surface 252 is, for example, arranged on another component 104 or formed by the other component 104.

[0414] The running surface 252 can therefore, for example, form a connecting element 130 of the connecting means 100.

[0415] It can be advantageous if the running surface 252 is formed by a contact surface 108 of the further component 104.

[0416] In the assembled state of the connecting element 100 and the components 102, 104, the bearing element 246 preferably rests against the running surface 252 and is movable along the running surface 252. Thus, the components 102, 104 are also movable relative to each other.

[0417] Moreover, the one in the Fig. 42 and Fig. 43 shows the thirteenth embodiment of a connecting element 100 with regard to structure and function compared to the one described in the Fig. 40 and Fig. 41 corresponds to the twelfth embodiment shown, so that reference is made to its preceding description in this respect.

[0418] One in the Fig. The fourteenth embodiment of a connecting element 100, illustrated in Figures 44 to 46, differs from the one shown in the Fig. The fifth embodiment shown in figures 23 to 26 differs essentially in that the connection of the connecting elements 130 to each other is achieved by means of a rotatable retaining element 142 in accordance with the provisions shown in the Fig. The second embodiment shown in Figures 10 to 15 can be produced.

[0419] Furthermore, in the Fig. In the embodiment of the connecting element 100 shown in Figures 44 to 46, no fixed insertion projections 166 are provided.

[0420] The connecting means 100 comprises a positioning device 254 for positioning the components 102, 104, in particular the connecting elements 130, relative to each other.

[0421] The positioning device 254 comprises one or more positioning elements 256 and one or more positioning element receptacles 258.

[0422] The positioning elements 256 are preferably mounted in a movable, compliant, elastic and / or spring-loaded manner.

[0423] During the Fig. In the embodiment of a connecting element 100 shown in Figures 44 to 46, two positioning elements 256 designed as steel balls 260 are provided, which are arranged slidably within each of a passage opening 262 on one of the connecting elements 130.

[0424] In the passage openings 262, a spring element 264 and a locking element 266, for example a setscrew 268, are also arranged.

[0425] Towards the mounting surface 152 of the base body 134, at least one passage opening 262 is tapered, so that one or more retaining projections 270 are formed.

[0426] The retaining projections 270 preferably prevent an unwanted escape of a positioning element 256, in particular a steel ball 260, from the passage opening 262.

[0427] The locking element 266 prevents the positioning element 256 from escaping at one end of the passage opening 262 opposite the contact surface 152.

[0428] The spring element 264 is arranged between the locking element 266 and the positioning element 256. In this way, the positioning element 256 is preferably resiliently held in a positioning position.

[0429] In this positioning position, the positioning element 256 extends beyond the mounting surface 152.

[0430] One or more positioning element receptacles 258 are preferably designed to be at least partially complementary to the one or more positioning elements 256. In particular, the positioning element receptacles 258 are designed to be complementary to the sections of the positioning elements 256 that extend beyond the contact surface 152 in their positioning position.

[0431] Due to the spring-loaded, flexible mounting of the positioning elements 256, these can be moved into the base body 134, in particular to be able to move the connecting elements 130 and the components 102, 104 relative to each other, while the contact surfaces 152 and / or the contact surfaces 106, 108 are in contact with each other.

[0432] Once the connecting elements 130 are arranged in a desired position, in which the positioning elements 256 are arranged opposite the positioning element receptacles 258, the positioning elements 256 are automatically moved into the positioning element receptacles 258 by means of the spring elements 264.

[0433] This allows for easy positioning of components 102 and 104 relative to each other. Furthermore, components 102 and 104 can be locked together in this way, for example to facilitate the actuation of the retaining element 142 for a stable connection between components 102 and 104.

[0434] In particular for gluing components 102, 104 together, it can also be provided that the connecting element 100 comprises exclusively a positioning device 254 and no holding element 142.

[0435] The in the Fig. The fourteenth embodiment of a connecting means 100 shown in Figures 44 to 46 is particularly suitable for mounting inserted shelves, partitions, back panels, cabinet elements, etc.

[0436] Furthermore, the connecting element 100 can be used as a gluing aid in places where no pressure can be applied and where it is impossible to insert or otherwise engage two connecting elements 130 with each other.

[0437] Moreover, the one in the Fig. The fourteenth embodiment of the connecting element 100, illustrated in Figures 44 to 46, differs in structure and function from that shown in the Fig. The fifth embodiment shown in Figures 23 to 26 is identical, so reference is made to its preceding description.

[0438] One in the Fig. The fifteenth embodiment of a connecting element 100, illustrated in Figures 47 to 49, differs from the one shown in the Fig. The ninth embodiment shown in Figures 32 to 34 is essentially distinguished by the fact that the connecting elements 130 and thus also the components 102, 104 can be connected or joined together by means of a hinge element 272 of a hinge device 274.

[0439] Two connecting elements 130 are provided, each of which can be inserted into a groove 110 on one of the components 102, 104.

[0440] Each of the connecting elements 130 includes two screw receptacles 230 for receiving screws 162.

[0441] The hinge element 272 comprises two sections 276 that can pivot relative to each other.

[0442] Each of the sections 276 includes two elongated holes 278 for passing the screws 162 and for fixing the respective section 276 to one of the connecting elements 130.

[0443] For easy and / or aesthetically pleasing mounting of the hinge element 272 to the connecting elements 130, recesses 280 can be provided in the connecting elements 130.

[0444] In these recesses 280, in particular, projecting tabs 282 of the sections 276 of the hinge element 272 can be received.

[0445] The elongated holes 278 are preferably arranged and / or formed in these tabs 282.

[0446] The hinge element 272 can, for example, be a metallic component or be made up of metallic components.

[0447] How in particular Fig. As can be seen from Figure 49, the connecting elements 130 and the components 102, 104 can be pivoted about a pivot axis 284 by means of the hinge element 272.

[0448] The in the Fig. The fifteenth embodiment of a connecting element 100 shown in Figures 47 to 49 is particularly suitable for use as a door hinge.

[0449] Moreover, the one in the Fig. The fifteenth embodiment of a connecting element 100, illustrated in sections 47 to 49, differs in structure and function from that described in the Fig. The ninth embodiment shown in Figures 32 to 34 is identical, so reference is made to its preceding description.

[0450] One in the Fig. The sixteenth embodiment of a connecting element 100, illustrated in Figures 50 to 53, differs from the one shown in the Fig. 27 and Fig. The sixth embodiment shown in 28 differs essentially in that a locking mechanism is provided instead of a screw connection to connect the two connecting elements 130 to each other.

[0451] The connecting element 100 comprises a movable, in particular linearly displaceable, locking element 286.

[0452] The locking element 286 is part of a connecting element 130 which can be inserted into a groove 110 and which, in addition to the base body 134 and the locking element 286, includes a drive shaft 288 and one or more magnetic elements 190 for driving the drive shaft 288.

[0453] How especially the Fig. 52 and Fig. As can be seen from Figure 53, the locking element 286 has an opening 292, which is essentially cuboid in shape and includes on one side a rack section 294 of a gear device 296.

[0454] The rack section 294 is in engagement with a gear 298 of the gear device 296, which is arranged on the drive shaft 288.

[0455] The magnetic elements 190 are also arranged on the drive shaft 288, so that the drive shaft 288 together with the gear 298 can be rotated about a rotational axis 300 by means of the magnetic elements 190, in particular by external contactless actuation by means of a magnetic device.

[0456] Due to the coupling of the gear 298 with the rack section 294 of the locking element 286, the locking element 286 can be linearly displaced by rotating the drive shaft 288, in particular along a locking direction 302.

[0457] The locking direction 302 is in particular essentially perpendicular to the contact surface 152 and / or to the contact surface 106, 108 of at least one of the components 102, 104.

[0458] The locking element 286 can be linearly displaceable in a locking element receptacle 304 of the base body 134 which is essentially complementary to it.

[0459] The drive shaft 288 together with the magnetic elements 190 and the gear 298 is to be received or received in a shaft receptacle 306 of the base body 134 of the connecting element 130.

[0460] The locking element 286 is preferably movable into the base body 134 along the locking direction 302 to such an extent that the locking element 286 no longer protrudes beyond the contact surface 152 and / or the contact surface 106, 108 of at least one component 102, 104.

[0461] In this position, however, the locking element 286 may protrude beyond the base body 134 at one end of the locking element receptacle 304 opposite the contact surface 152 of the base body 134.

[0462] This position of the locking element 286 can therefore only be realized if the base body 134 is dimensioned large enough to accommodate the entire locking element 286, or if the component 102 in which the connecting element 130 having the locking element 286 is arranged is provided with a recess 308 adjoining the locking element receptacle 304 in the locking direction 302 (see Fig. 51).

[0463] For locking two components 102, 104 together by means of the connecting element 100, the locking element 286 is, for example, inserted into the Fig. 50 and Fig. 51 can be brought into the locking position shown, in which the locking element 286 projects beyond the contact surface 152 of the connecting element 130 and beyond the contact surface 106 of the component 102.

[0464] The locking element 286 then extends, for example, into a locking element receptacle 304 of a further connecting element 130, which is arranged in the further component 104. Alternatively or additionally, it can be provided that the further component 104 only comprises a recess 308 for receiving the locking element 286.

[0465] To optimize torque transmission from the magnetic elements 190 to the drive shaft 288 and / or the gear 298, a drive shaft 288 with a non-rotationally symmetrical cross-section, for example a rectangular cross-section, is provided. The magnetic elements 190 and the gear 298 then preferably have corresponding receptacles.

[0466] The drive shaft 288 can, for example, be a bar magnet.

[0467] Preferably, the magnetic elements 190, the drive shaft 288, the gear 298 and / or the rack section 294 of the locking element 286 are dimensioned, designed and / or arranged such that the locking element 286 can be moved from a holding position to a release position, in particular from a locking position to a release position, by rotating the drive shaft 288 by 180°.

[0468] By applying a magnet to different side surfaces of component 102, the locking element 286 can then be brought into the desired different positions particularly easily.

[0469] The in the Fig. The sixteenth embodiment of the connecting element 100, illustrated in Figures 50 to 53, is particularly suitable for use as a furniture lock, as a shelf connector and / or for wall panel mounting.

[0470] Moreover, the one in the Fig. The sixteenth embodiment of the connecting element 100, illustrated in Figures 50 to 53, is comparable in structure and function to that described in the Fig. 27 and Fig. 28 corresponds to the sixth embodiment shown, so reference is made to its preceding description in this respect.

[0471] One in Fig. The seventeenth embodiment of a connecting element 100, illustrated in Figure 54, differs from the one shown in the Fig. The sixteenth embodiment shown in Figures 50 to 53 is essentially distinguished by the fact that two connecting elements 130 are provided, each comprising at least one magnetic element 190.

[0472] The magnetic element 190 can, for example, be completely integrated into the base body 134 of a connecting element 130, in particular arranged within the base body 134 at a distance from the contact surface 152 of the base body 134.

[0473] However, it can also be provided that the magnetic element 190 extends within the base body 134 up to the contact surface 152.

[0474] At the in Fig. In the seventeenth embodiment of the connecting means 100 shown in Figure 54, the connecting elements 130 and thus also the components 102, 104 are connected to each other by the magnetic elements 190 interacting magnetically with each other, in particular by the magnetic elements 190 attracting each other.

[0475] The components 102, 104 are thus brought into a position by means of the connecting means 100 in which the distances of the magnetic elements 190 from each other are minimal.

[0476] Components 102 and 104 do not necessarily have to be in contact with each other, and in particular do not have to be touching each other. Rather, it is possible for components 102 and 104 to be arranged at any distance A from each other.

[0477] The connecting elements 130 of the connecting device 100 also do not need to be mechanically engaged with each other.

[0478] It is therefore not crucial that the connecting elements 130 are arranged in grooves 110 which adjoin the contact surfaces 106, 108 of the components 102, 104.

[0479] Rather, it may be provided that, for example, at least one connecting element 130 is arranged in a groove 110, which adjoins a side surface 310 oriented perpendicular to the contact surface 106, for example an end surface 312 of the component 102.

[0480] In particular, for the aesthetically pleasing design of the components 102, 104, it may be provided that the surfaces 108, 310, in which the grooves 110 and thus also the connecting elements 130 are arranged, are each provided with a cover element 314 after the assembly of the connecting elements 130.

[0481] The cover element 314 can, for example, form an edge of the component 102, 104.

[0482] As in previous embodiments, a magnetic element 190 is to be understood as a magnetically interacting element.

[0483] The two magnetic elements 190 do not necessarily both have to be magnetized. Rather, for example, one magnetized magnetic element 190 and one magnetizable element, in particular a steel element, can be provided.

[0484] The in Fig. The seventeenth embodiment of the connecting element 100 shown in Figure 54 is particularly suitable for use in or on furniture doors and office furniture with an invisible, quick-to-mount catch for magnetic fixing of a door.

[0485] Moreover, the in Fig. 54 shows the seventeenth embodiment of a connecting element 100 with regard to structure and function compared to the one described in the Fig. The sixteenth embodiment shown in Figures 50 to 53 is identical, so reference is made to its preceding description.

[0486] One in the Fig. 55 and Fig. The eighteenth embodiment of a connecting element 100, illustrated in section 56, differs from the one shown in the Fig. The first embodiment shown in Figures 5 to 9 is essentially characterized by the fact that the screw element 132 is rotatably arranged on the connecting element 130, which can be inserted into a groove 110.

[0487] Instead of a rotatable holding element 142 for gripping the screw element 132, an actuating element 316 is provided for actuating the screw element 132.

[0488] The actuating element 316 and the screw element 132 form in particular an angle-driven screw device 318.

[0489] How in particular Fig. As can be seen from Figure 56, the angle-driven screw device 318, in particular the actuating element 316, is accessible laterally through an access bore 128 in a component 102. The screw element 132 can be screwed directly into the further component 104 without any additional elements.

[0490] However, it may also be provided that the further component 104 includes a screw receptacle 230, is provided with a screw receptacle 230 or is provided with a connecting element 130 having a screw receptacle 230, which can be arranged in a groove 110 in the component 104.

[0491] As an alternative to actuating a screw element 132 by means of the actuating element 316, it can also be provided that a nut can be actuated by means of the actuating element 316 in order to receive a screw arranged on the further component 104.

[0492] These fasteners 100 can be used, in particular, to create connections with non-wood materials. Furthermore, these fasteners 100 are suitable for use in or as shelf supports.

[0493] Moreover, the one in the Fig. 55 and Fig. 56 depicts the eighteenth embodiment of a connecting element 100 with regard to structure and function compared to the one described in the Fig. The first embodiment shown in sections 5 to 9 is identical, so reference is made to its preceding description.

[0494] One in Fig. The nineteenth embodiment of a connecting element 100, as illustrated in Figure 57, differs from the one shown in the Fig. The ninth embodiment shown in Figures 32 to 34 differs essentially in that one of the connecting elements 130 comprises a movable retaining element 142, which is designed as a locking hook 320.

[0495] The locking hook 320 can in particular be engaged with a locking receptacle 322, which is arranged on the further connecting element 130.

[0496] The locking hook 320 is arranged in a resilient manner on the connecting element 130, in particular by means of a spring element 264.

[0497] In particular, the locking hook 320 can be moved along the connection direction 170 from a locking position (see Fig. 57), in which the locking hook 320 extends beyond the contact surface 152 of the connecting element 130, is brought into a release position in which the locking hook 320 is substantially completely located within the base body 134 of the connecting element 130.

[0498] The locking hook 320 and / or the locking receptacle 322 is preferably provided with at least one inclined surface 324.

[0499] The inclined surface 324 is in particular inclined to the mounting surface 152 and / or to the contact surfaces 106, 108 of the components 102, 104.

[0500] The inclined surfaces 324 enable the locking hook 320 to be inserted into the base body 134 when the components 102, 104 and thus also the connecting elements 130 are moved in a transverse direction 326 parallel to the contact surface 152 and / or to the contact surfaces 106, 108.

[0501] However, this is preferably only possible in a single transverse direction 326.

[0502] The components 102, 104 and the connecting elements 130 are preferably designed and / or arranged such that this transverse direction 326 for disengaging the locking hook 320 is directed against a gravity direction g.

[0503] When the component 102 is subjected to a load in a transverse direction 326 parallel to the direction of gravity g, the locking hook 320 preferably remains in the locking receptacle 322, so that a reliable and stable connection between the components 102, 104 is ensured.

[0504] The in Fig. The nineteenth embodiment of a connecting element 100 shown in Figure 57 is particularly suitable for use as a shelf support.

[0505] Moreover, the in Fig. 57 depicted nineteenth embodiment of a connecting element 100 with regard to structure and function compared to the one described in the Fig. The ninth embodiment shown in Figures 32 to 34 is identical, so reference is made to its preceding description.

[0506] One in the Fig. The twentieth embodiment of a connecting element 100, illustrated in Figures 58 to 60, differs from the one shown in the Fig. The ninth embodiment shown in Figures 32 to 34 differs essentially in that the connecting means 100 serves, on the one hand, to connect two components 102, 104 and, on the other hand, to connect the components 102, 104 with one or more further components, in particular with a base structure 328.

[0507] A basic construction 328 is in particular a substructure of a floor covering or wall paneling.

[0508] How especially the Fig. 58 and Fig. As can be seen from 60, the connecting means 100 comprises a connecting element 130 which can be inserted into a groove 110 in one of the components 102, 104.

[0509] The connecting element 130, for example, is formed in one piece and, in addition to a part 330 that can be inserted into the groove 110, includes a projection 332 and a surrounding section 334.

[0510] The projection 332 serves in particular for the arrangement and / or reception of the further component 104.

[0511] The further component 104 can be slid onto the projection 332, in particular by means of a recess 336, for example a groove 110.

[0512] The encompassing section 334 of the connecting element 130 surrounds the component 102 on a side surface 310 running transversely, in particular essentially perpendicularly, to the contact surface 106.

[0513] The connecting element 130 thus surrounds the component 102 section by section in an essentially C-shaped manner.

[0514] The encompassing section 334 can, for example, extend parallel to the projection 332, so that the further component 104, in its assembled state, is also essentially C-shaped and encompassed by the connecting element 130.

[0515] How in particular Fig. As can be seen from Figure 60, a passage opening 154 is provided between the projection 332 and the part 330 of the connecting element 130 which forms the base body 134 of the connecting element 130.

[0516] A screw 162 can be inserted into this passage opening 154, in particular to fix the connecting element 130 together with the component 102 or together with both components 102, 104 to the base structure 328, in particular to screw it in place.

[0517] Due to the encompassing section 334 of the connecting element 130, one or more components 102, 104 preferably do not rest directly on the base structure 328.

[0518] Rather, a distance A2 is preferably formed between the one or more components 102, 104 by means of the encompassing section 334.

[0519] Furthermore, components 102 and 104 are preferably held at a predetermined distance A1 from each other by means of the connecting element 130.

[0520] The in the Fig. The twentieth embodiment of the connecting element 100, shown in Figures 58 to 60, is particularly suitable as a terrace connector for connecting boards (components 102, 104) to each other and to a beam construction (base construction 328).

[0521] For assembly, it may be provided, for example, that a component 102 is provided with one or more grooves 110.

[0522] At least one groove 110 is then provided with a connecting element 130 by inserting the part 330 of the connecting element 130, which forms the base body 134, into the groove 110.

[0523] The encompassing section 334 of the connecting element 130 encompasses the component 102 on its side surface 310.

[0524] In the next step, component 102 is placed on the base structure 328 together with the connecting element 130.

[0525] In particular, the encompassing section 334 of the connecting element 130 and the base structure 328 are brought into contact with each other and screwed together by means of one or more screws 162.

[0526] Another component 104 is then fixed to the base structure 328 by being pushed onto the projection 332 of the connecting element 130 with a prepared recess 336 or groove 110.

[0527] On one side of component 104, which is opposite the side of component 104 that serves to receive the projection 332, a further groove 110 is provided, into which a further connecting element 130 is inserted in order to fix it together with the further component 104 to the base structure 328.

[0528] To release the connection, only screws 162 need to be removed.

[0529] Components 102 and 104 can then preferably be moved relative to each other in order to remove individual components 102 and 104.

[0530] Moreover, the one in the Fig. 58 to 60, the twentieth embodiment of a connecting element 100, is shown with regard to structure and function, compared to the embodiment shown in the Fig. The ninth embodiment shown in Figures 32 to 34 is identical, so reference is made to its preceding description.

[0531] One in the Fig. 61 and Fig. The twenty-first embodiment of a connecting element 100, illustrated in section 62, differs from the one shown in the Fig. The ninth embodiment shown in 32 to 34 is essentially distinguished by the fact that the connecting element 100 comprises several spring elements 338 or locking elements 340 by means of which the connecting elements 130 and thus also the components 102, 104 can be connected to one another, in particular locked together.

[0532] The spring elements 338 or detent elements 340 have spring lugs 342 or detent lugs 344 which can be engaged with corresponding receptacles 346.

[0533] For the sake of simplicity, the spring elements 338 and the detent elements 340 will be referred to uniformly as "detent elements 340" below.

[0534] The spring noses 342 and the locking noses 344 are therefore uniformly referred to as "locking noses 344".

[0535] How in particular Fig. As can be seen from 61, the following are in the Fig. 61 and Fig. In the twenty-first embodiment of a connecting element 100 shown in Figure 62, both connecting elements 130 are each provided with locking elements 340 and with receptacles 346 for the locking lugs 344 of the locking elements 340.

[0536] The locking elements 340 and the receptacles 346 are arranged relative to each other in such a way that two locking elements 340 can be guided past each other by different connecting elements 130 and engaged with the respective receptacle 346.

[0537] How in particular Fig. As can be seen from 62, it may be provided, for example, that each connecting element 130 comprises eight locking elements 340 and eight receptacles 346.

[0538] The locking lugs 344 of the locking elements 340 are preferably arranged at different distances from the contact surface 152 of the respective connecting element 130. This enables improved locking of the connecting elements 130 and thus an improved connection of the components 102, 104.

[0539] For example Fig. As can be seen from Figure 61, adjacent locking elements 340 are preferably oriented such that the locking lugs 344 of the locking elements 340 protrude in different directions from each other.

[0540] Furthermore, it can be provided that each connecting element 130 comprises two or more locking elements 340 which are arranged adjacent to each other, wherein locking elements 340 that are directly adjacent to each other are preferably designed and / or arranged such that their locking lugs 344 protrude in different directions from each other.

[0541] Moreover, the one in the Fig. 61 and Fig. 62 illustrated twenty-first embodiment of a connecting element 100 with regard to structure and function with the one described in the Fig. The ninth embodiment shown in Figures 32 to 34 is identical, so reference is made to its preceding description.

[0542] One in the Fig. The twenty-second embodiment of a connecting element 100, illustrated in Figures 63 to 67, differs from the one shown in the Fig. 61 and Fig. The twenty-first embodiment shown in Figure 62 differs essentially in that only one connecting element 130 is provided, which comprises spring elements 338 and / or locking elements 340.

[0543] With regard to this embodiment as well, reference will be made exclusively to detent elements 340 for the sake of uniformity. However, these detent elements 340 can also be simple spring elements 338.

[0544] During the Fig. In the twenty-second embodiment of a connecting element 100 shown in Figures 63 to 67, a connecting element 130, which can be inserted into a groove 110, is provided with two rows 348 of locking elements 340.

[0545] The rows 348 are arranged parallel to each other.

[0546] The locking lugs 344 of the locking elements 340 of a row 348 protrude in the same direction.

[0547] The locking lugs 344 of each row 348 are arranged along a circular arc path.

[0548] How especially the Fig. 65 and Fig. As can be seen from Figure 67, the locking elements 340 are arranged such that the locking lugs 344 of the locking elements 340 protrude in a direction away from the other row 348.

[0549] The length of the locking elements 340, that is, the distance of the locking lugs 344 of the locking elements 340 from the contact surface 152 of the connecting element 130, is preferably selected such that the locking lugs 344 engage in a groove 110 of the Fig. 1 to 4 of the type shown can be inserted and locked into place on the undercut surfaces 122 of the groove 110.

[0550] With just one connecting element 130 and two grooves 110, a simple snap-fit ​​connection between two components 102, 104 can thus be made.

[0551] Preferably the locking lugs 344 are provided with (not shown) inclined surfaces so that the components 102, 104 can be pulled towards each other when the locking lugs 344 are engaged.

[0552] Moreover, the one in the Fig. The twenty-second embodiment of a connecting element 100, illustrated in sections 63 to 67, is comparable in structure and function to that shown in the Fig. 61 and Fig. The twenty-first embodiment shown in Figure 62 is identical, so reference is made to its preceding description.

[0553] One in the Fig. The twenty-third embodiment of a connecting element 100, illustrated in Figures 68 to 70, differs from the one shown in the Fig. 61 and Fig. The twenty-first embodiment shown in Figure 62 differs essentially in that one or more locking elements 350 are provided instead of detent elements 340.

[0554] A locking element 350 forms in particular a retaining element 142.

[0555] The locking element 350 can, for example, be designed as a metal bent part 352.

[0556] How in particular Fig. As can be seen from 68, the locking element 350 can be received in a receptacle 354 of a connecting element 130.

[0557] The locking element 350 is preferably an element different from the base body 134 of the connecting element 130, which can be detachably fixed to the base body 134 in particular.

[0558] The locking element 350 comprises, for example, two engagement projections 146, which are designed and / or arranged to be movable relative to the base body 134 of the connecting element 130.

[0559] The further connecting element 130 includes an actuating element 316 for actuating the locking element 350.

[0560] The actuating element 316 is designed, for example, as an eccentric element.

[0561] Preferably, the actuating element 316 is accessible through a lateral access bore 128 in one of the components 102, 104, in particular to turn the actuating element 316 by means of a wrench and thus actuate the locking element 350.

[0562] How especially the Fig. 69 and Fig. As can be seen from Figure 70, the locking element 350 can be actuated by means of the actuating element 316, in particular by moving the engagement projections 146 away from each other by means of the actuating element 316 and thereby bringing them into the engagement sections 148 on the connecting element 130 on which the actuating element 316 is arranged.

[0563] By arranging the locking element 350 and the actuating element 316 on separate connecting elements 130, the lever arm ratios for actuating the locking element 350 can be optimized. This reduces the mechanical stress on the connecting element 100 when locking it, while preferably maintaining or even improving the stability and reliability of the connection.

[0564] Moreover, the one in the Fig. The twenty-third embodiment of a connecting element 100, illustrated in sections 68 to 70, is comparable in structure and function to that described in the Fig. 61 and Fig. The twenty-first embodiment shown in Figure 62 is identical, so reference is made to its preceding description.

[0565] One in the Fig. The twenty-fourth embodiment of a connecting element 100, illustrated in Figures 71 to 74, differs from the one shown in the Fig. 61 and Fig. The twenty-first embodiment shown in 62 differs essentially in that a clamping device 356 is provided instead of the locking elements 340.

[0566] The clamping device 356 comprises one or more clamping projections 358 and one or more clamping elements 360.

[0567] For example, a clamping projection 358 is arranged on one of the connecting elements 130 that can be inserted into a groove 110.

[0568] The clamping elements 360, for example four clamping elements 360, are arranged on the further connecting element 130.

[0569] In particular, the clamping elements 360 are arranged on opposite sides of a clamping receptacle 362.

[0570] The clamping projection 358 is essentially cuboid in shape.

[0571] The clamping elements 360 are preferably provided with a material with a high coefficient of friction or formed from a material with a high coefficient of friction at their ends that come into contact with the clamping projection 358.

[0572] The clamping elements 360 are preferably designed to be flexible, elastic and / or spring-loaded and / or arranged on the base body 134 of the connecting element 130.

[0573] The clamping elements 360 preferably project obliquely into the clamping receptacle 362 relative to the contact surface 152. Furthermore, the clamping elements 360 are preferably directed away from the contact surface 152.

[0574] When inserting the clamping projection 358 into the clamping receptacle 362, the clamping elements 360 can simply be moved to the side. The clamping projection 358 can thus be inserted into the clamping receptacle 362 without significant resistance (see Fig. 73 and Fig. 74).

[0575] The connection between the connecting elements 130 and thus the connection between two components 102, 104 can therefore be easily established.

[0576] To release the connection, the clamping projection 358 must be pulled out of the clamping receptacle 362.

[0577] However, due to the shape and design of the clamping elements 360, a large resistance results, especially due to the fact that the clamping elements 360 are moved towards the clamping projection 358 by the inclined arrangement and orientation, thus further increasing the clamping force.

[0578] The clamping device 356 is therefore a self-locking clamping device 356.

[0579] The 360 ​​clamping elements can, for example, be designed as pressure combs.

[0580] The clamping projection 358 is in particular a substantially cuboid-shaped pin.

[0581] Moreover, the one in the Fig. The twenty-fourth embodiment of a connecting element 100, illustrated in figures 71 to 74, is comparable in structure and function to that shown in the Fig. 61 and Fig. The twenty-first embodiment shown in Figure 62 is identical, so reference is made to its preceding description.

[0582] One in Fig. The twenty-fifth embodiment of a connecting element 100, illustrated in section 75, differs from the one shown in the Fig. 61 and Fig. The twenty-first embodiment shown in Figure 62 differs essentially in that the locking elements 340 and the receptacles 346 for the locking elements 340 are essentially spherical.

[0583] The locking elements 340 and / or the receptacles 346 for the locking elements 340 are preferably designed to be elastic and / or flexible.

[0584] For example, it may be provided that the spherical locking elements 340 are deformable in order to be inserted into the also spherical receptacles 346.

[0585] At the in Fig. In the twenty-fifth embodiment of the connecting element 100 shown in Figure 75, the locking elements 340 and the receptacles 346 are provided on different connecting elements 130.

[0586] The spherical locking elements 340 are arranged at different distances from the contact surface 152. This enables optimized locking of the components 102 and 104 together.

[0587] In particular, if the receptacles 346 for the locking elements 340 are arranged at the same distance from the contact surface 152 of the respective connecting element 130, it can be provided that the spherical locking elements 340 are inserted one after the other into the receptacles 346 and locked into place with them.

[0588] Preferably, this allows the connecting element 100 to be locked in different positions, in particular at different distances between the contact surfaces 152 of the connecting elements 130.

[0589] Moreover, the in Fig. 75 illustrated twenty-fifth embodiment of a connecting element 100 with regard to structure and function with that described in the Fig. 61 and Fig. The twenty-first embodiment shown in Figure 62 is identical, so reference is made to its preceding description.

[0590] One in the Fig. The twenty-sixth embodiment of a connecting element 100, illustrated in Figures 76 to 78, differs from the one shown in Fig. 75 illustrated twenty-fifth embodiment essentially in that the locking elements 340 are essentially shaped in the form of circular cylinder segments and can be inserted into corresponding essentially circular cylinder segment-shaped receptacles 346.

[0591] Moreover, the one in the Fig. The twenty-sixth embodiment of a connecting element 100, illustrated on pages 76 to 78, is comparable in structure and function to the embodiment shown in Fig. 75 corresponds to the twenty-fifth embodiment shown, so that reference is made to its preceding description in this respect.

[0592] In the Fig. 79 and Fig. 80 shows an alternative design of a groove 110.

[0593] This groove 110 is designed as a partial groove 364.

[0594] In this partial groove 364, the groove base surface 118 extends in a circular arc from the contact surface 106 of the component 102 into the component 102. However, the groove base surface 118 does not end again at the contact surface 106, but rather within the component 102 or at a side surface 310 of the component 102 (not shown in the drawings).

[0595] During the Fig. 79 and Fig. In the embodiment of a groove 110 shown in Figure 80, the groove base surface 118 ends at a stop surface 366 of the groove 110.

[0596] The stop surface 366 runs in particular perpendicular to the contact surface 106.

[0597] The stop surface 366 preferably limits the base section 112 and the undercut sections 114.

[0598] By suitably shortening the design of the connecting elements 130, preferably all connecting elements 130 which are in a groove 110 according to the Fig. 1 to 4 can be arranged, also in a partial groove 364 according to the Fig. 79 and Fig. 80 can be arranged.

[0599] The partial groove 364 can be produced, for example, using a (not shown) finger cutter.

[0600] One in Fig. The twenty-seventh embodiment of a connecting element 100, illustrated in 81, differs from the one shown in the Fig. The twenty-fourth embodiment shown in Figures 71 to 74 differs essentially in that the connecting means 100 comprises a locking device 368.

[0601] By means of the locking device 368, the connecting element 130 can preferably be secured against unwanted displacement of the same within and / or along the groove 110.

[0602] The locking device 368 comprises in particular a locking element 370 designed as a locking projection, which, in the assembled state of the connecting element 130, comes into contact in particular with a contact surface 106, 108 of a component 102, 104 and thereby secures the connecting element 130 against unwanted displacement within and / or along the groove 110.

[0603] The locking element 370 can be clamped in particular between the components 102, 104, for example between the contact surfaces 106, 108 of the components 102, 104, in order to secure the connecting element 130.

[0604] Moreover, the in Fig. 81, the twenty-seventh embodiment of a connecting element 100, is shown to be similar in structure and function to that described in the Fig. The twenty-fourth embodiment shown in Figures 71 to 74 is identical, so reference is made to its preceding description.

[0605] One in the Fig. The twenty-eighth embodiment of a connecting element 100, illustrated in Figures 82 to 87, differs from the one shown in Fig. 81 twenty-seventh embodiment, in particular in that the locking device 368 comprises two pairs of locking elements 370, which are arranged at opposite end regions 374 of the respective connecting element 130 with respect to an insertion direction 372 of the connecting elements 130.

[0606] The locking elements 370 are in particular elastically, flexibly and / or resiliently designed and / or arranged locking elements 370.

[0607] When the connecting elements 130 are inserted into the grooves 110, the locking elements 370 are preferably moved automatically into a release position.

[0608] As soon as the connecting elements 130 are arranged in the specified position in the groove 110, in particular as soon as the contact surface 152 of the connecting element 130 is aligned parallel, in particular flush, with the contact surface 106, 108 of the component 102, 104, the locking elements 370 preferably automatically enter a holding position in which further displacement of the connecting element 130 within and / or along the groove 110 is effectively prevented.

[0609] The locking elements 370 then rely in particular on the contact surface 106, 108 of at least one of the components 102, 104.

[0610] During the Fig. In the twenty-eighth embodiment of the connecting means 100 shown in Figures 82 to 87, the actual connection of the two connecting elements 130 and the components 102, 104 to each other is effected by a guide device 238.

[0611] The guide device 238 comprises a guide element 240 arranged on a connecting element 130, which includes one or more guide projections 242.

[0612] The guide element 240 can in particular be inserted into a guide groove 244 of the further connecting element 130.

[0613] This guide groove 244 includes a guide section 250, which can be engaged by the guide element 240 by means of the guide projections 242.

[0614] The guide device 238 includes in particular a cam guide 376, which is formed by the guide groove 244.

[0615] The scenery guide 376 serves in particular to guide the guide element 240 along a predetermined guide path.

[0616] This guide path has varying distances along the guide groove 244 from the contact surfaces 106, 108 of the components 102, 104 and / or from the contact surfaces 152 of the connecting elements 130.

[0617] In particular, the scenery guidance 376 provides for a local minimum area 378, which is surrounded by two local or global maximum areas 380.

[0618] The maximum areas 380 are surrounded on the side facing away from the minimum area 378 by outlet areas 382.

[0619] To connect the connecting elements 130 and the components 102, 104 to each other, the connecting elements 130 are first arranged on the components 102, 104.

[0620] In a next step, the components 102, 104 together with the connecting elements 130 arranged on them are moved relative to each other, so that the guide element 240 of one connecting element 130 enters the guide groove 244 of the other connecting element 130.

[0621] The components 102, 104 and the connecting elements 130 are displaced in particular parallel to the contact surfaces 106, 108 of the components 102, 104.

[0622] The leading edge 242 first engages with a run-out area 382 and is then guided over the maximum area 380 into the minimum area 378.

[0623] Due to the further maximum range 380 following this minimum range 378, this minimum range 378 is a stable position for the guide projection 242 along the guide path formed by means of the cam guide 376.

[0624] The connecting elements 130 are thus stably connected to each other when the guide projection 242 is arranged in the minimum area 378 of the cam guide 376 (see in particular Fig. 86).

[0625] If required, the guide projection 242 together with the associated connecting element 130 and the associated component 102, 104 can also be pushed out beyond the further maximum range 380 and out of the further run-out range 382.

[0626] The connecting elements 130 can therefore be completely slid past each other if required.

[0627] How especially the Fig. 83 and Fig. As can be seen from 86, a recess 384 may be provided in one or more connecting elements 130 in an area facing away from the mounting surface 152.

[0628] This indentation 384, for example, is shaped like a circular arc.

[0629] Such a recess 384 can be particularly advantageous if the connecting element 130 is to be arranged in a flat component 102, 104 and in addition to this connecting element 130 further guide elements 240 are provided on the same component 102, 104.

[0630] For example, if two grooves 110 for receiving connecting elements 130 are arranged on opposite sides of a component 102, 104 and the grooves 110 extend so far into the component 102, 104 that the grooves 110 overlap in the area of ​​the groove base surfaces 118, the indentation 384 can make it possible to arrange two connecting elements 130 in the component 102, 104 despite the overlap.

[0631] Moreover, the one in the Fig. The twenty-eighth embodiment of a connecting element 100, illustrated on pages 82 to 87, is comparable in structure and function to the embodiment shown in Fig. 81 corresponds to the twenty-seventh embodiment shown, so that reference is made to its preceding description in this respect.

[0632] One in the Fig. The twenty-ninth embodiment of a connecting element 100, illustrated in Figures 88 to 92, differs from the one shown in the Fig. The twenty-eighth embodiment shown in Figures 82 to 87 differs essentially in that one of the connecting elements 130, in particular the connecting element 130 having the guide groove 244, is provided with a retaining projection 138 only on one side.

[0633] This connecting element 130 can therefore be inserted in particular into a groove 110 which comprises only an undercut section 114 extending away from the base section 112.

[0634] Such a groove 110 can be advantageous, for example, when using thin and less stable components 102, 104.

[0635] In principle, reducing the groove 110 and / or the connecting elements 130 to only one undercut section 114 or only one retaining projection 138 can be advantageous in all described and conceivable variants of grooves 110 and connecting elements 130.

[0636] Moreover, the one in the Fig. The twenty-ninth embodiment of a connecting element 100, illustrated on pages 88 to 92, is comparable in structure and function to that described in the Fig. The twenty-eighth embodiment shown in Figures 82 to 87 is identical, so reference is made to its preceding description.

[0637] One in the Fig. The thirtieth embodiment of a connecting element 100, illustrated in Figures 93 to 97, differs from the one shown in the Fig. The twenty-eighth embodiment shown in Figures 82 to 87 differs essentially in that one of the connecting elements 130, for example the connecting element 130 comprising the guide element 240, is not provided for insertion into a groove 110, but rather comprises two insertion sections 386 for insertion of the connecting element 130 into corresponding (not shown) receptacles of a component 102, 104.

[0638] The insertion sections 386 can, for example, be provided with a ribbed surface, with lamellae and / or other retaining elements in order to stably connect the connecting element 130 to the corresponding component 102, 104.

[0639] Moreover, the one in the Fig. The thirtieth embodiment of a connecting element 100, illustrated in 93 to 97, is comparable in structure and function to that shown in the Fig. The twenty-eighth embodiment shown in Figures 82 to 87 is identical, so reference is made to its preceding description.

[0640] One in the Fig. 98 and Fig. The thirty-first embodiment of a connecting element 100, illustrated in 99, differs from that shown in the Fig. The fifteenth embodiment shown in 47 to 49 is essentially distinguished by the fact that the connecting elements 130 themselves form hinge elements 272 of the hinge device 274.

[0641] The connecting elements 130 are designed such that they fit into partial grooves 364 (see the Fig. 79 and Fig. 80) are recordable.

[0642] In these partial grooves 364, it is particularly provided that the groove base surfaces 118 of the respective partial groove 364 each border on one side a contact surface 106, 108 and on the other side a side surface 310 of the respective component 102, 104.

[0643] The connecting elements 130 arranged in the partial grooves 364 can be fixed in the partial grooves 364 and thus in the components 102, 104 by means of screws 162.

[0644] By means of the hinge device 274, the connecting elements 130 and thus also the components 102, 104 can be pivoted about the pivot axis 284.
