[0120] Identical or functionally equivalent elements are provided with the same reference numerals throughout the figures. Referring to Figures 1 to 15, a connecting device 100 according to the invention is shown, which is suitable for connecting a first component and a second component.

[0121] Such components can in particular be furniture or machine parts.

[0122] Since the connecting device 100 according to an exemplary embodiment of the present invention, which is shown schematically in Fig. 1, and the elements of the connecting device 100 according to a further exemplary embodiment of the present invention, which are shown schematically in Figs. 2 to 14, and the connecting device 100 according to a further exemplary embodiment of the present invention, which is shown schematically in Fig. 15, are substantially the same and / or identical in nature, the three embodiments will be described together below for the sake of clarity, with particular differences between these embodiments being explicitly pointed out and / or described separately.

[0123] The connecting device 100 comprises a first connecting element 102 (see Figs. 9 to 14), which can be assigned to the first component.

[0124] In other words, the first connecting element 102 is arranged on the first component in the connected state of the components.

[0125] The connecting device 100 comprises a second connecting element 104 (see Figs. 2 to 8), which can be assigned to the second component.

[0126] In other words, the second connecting element 104 is arranged on the second component in the connected state of the components.

[0127] The first connecting element 102 has a first housing 106 and a holding element 108 which is movable, in particular pivotable and / or rotatable, relative to the first housing 106.

[0128] The retaining element 108 is configured and serves to connect the first connecting element 102 to the second connecting element 104.

[0129] It should be understood that the retaining element 108 may be configured to directly connect the first connecting element 102 to the second component. Thus, it may be conceivable that the second connecting element 104 may be optional for connecting a first component and a second component.

[0130] The movable holding element 108 has a first holding contour 110.

[0131] The second connecting element 104 has a second holding contour 112, which can be engaged behind the first holding contour 110.

[0132] In particular, the second connecting element 104 has a second housing 114 on or in which the second holding contour 112 is arranged.

[0133] In the event that the first connecting element 102 is to be connected directly to the second component, it should be understood that the second component has a second holding contour which can be engaged behind by the first holding contour 110.

[0134] If the second retaining contour 112 is engaged behind by the first retaining contour 110 (see Fig. 15), a relative movement of the first connecting element 102 and the second connecting element 104 (and / or the second component) along a specific direction can be prevented. This specific direction is a connection direction V.

[0135] At least one of the connecting elements 102, 104 has on the respective housing 106, 114 a curved surface 116, 118 which is circular in a longitudinal section, and a substantially flat access surface 120, 122 opposite this curved surface 116, 118, which faces the other connecting element 102, 104 when the components are connected.

[0136] In the present embodiments, the first connecting element 102 has a first curved surface 116 and a first access surface 120, which are respectively arranged on the first housing 106.

[0137] As can be seen particularly in Figs. 10 and 14, the first curved surface 116 is substantially circular in a longitudinal section.

[0138] The first access surface 120 is arranged opposite the first curved surface 116 on the first housing 106 and is substantially planar. The second connecting element 104 has a second curved surface 118 and a second access surface 122, each of which is arranged on the second housing 114.

[0139] As can be seen particularly in Figs. 3 and 8, the second curved surface 118 is substantially circular in a longitudinal section.

[0140] The second access surface 122 is arranged opposite the second curved surface 118 on the second housing 114 and is substantially planar.

[0141] The connection direction V is transverse and, in the present exemplary embodiments, substantially perpendicular to the respective access surfaces 120, 122.

[0142] A direction that is oriented substantially perpendicular to the connection direction V is in this case a thickness direction D.

[0143] In particular, the holding element 108 is transversely movable and / or movable with respect to the thickness direction D.

[0144] A direction that is oriented substantially perpendicular to the connecting direction V and substantially perpendicular to the thickness direction D is in this case a longitudinal direction L.

[0145] In other words, the longitudinal direction L is oriented substantially perpendicular to the thickness direction D and substantially parallel or coincident to the respective substantially planar access surfaces 120, 122.

[0146] As can be seen from Figs. 1 and 15, which illustrate a state corresponding to an at least partially connected state of the components, in the connected state of the components the first and second access surfaces 120, 122 face each other.

[0147] The first and second connecting elements 102, 104, in particular the first and second housings 106, 114, each extend in the thickness direction D and in the longitudinal direction L. In other words, the first and second connecting elements 102, 104, in particular the first and second housings 106, 114, have an extension in the thickness direction D and an extension in the longitudinal direction L.

[0148] As can be seen, for example, from Figs. 4, 5, 11 and 12, a ratio between the extension in the thickness direction D and the extension in the longitudinal direction L of the first and the second connecting element 102, 104, in particular the first and the second housing 106, 114, is less than or equal to 1 to 9, in particular less than or equal to 1 to 10, preferably less than or equal to 1 to 11.

[0149] In the respective embodiments of Figs. 1 and 15, this ratio is 1 to 25 ± 10%, whereas in the respective embodiment of Figs. 2 to 14, this ratio is substantially 1 to 15.

[0150] For example, the ratio between the extension in the thickness direction D and the extension in the longitudinal direction L can be between substantially 1 to 9 and substantially 1 to 25, in particular between substantially 1 to 10 and substantially 1 to 25, preferably between substantially 1 to 11 and substantially 1 to 25 (optionally in conjunction with a ±10% or ±5% tolerance). It should be understood that the aforementioned ratio values ​​can be considered in the sense of "less than" or "less than or equal to" and / or "greater than" or "greater than or equal to" accordingly.

[0151] The ratio between the extension in the thickness direction D and the extension in the longitudinal direction L may, for example, be substantially 1 to 15 as in the relevant embodiment of Figs. 2 to 14 (optionally in conjunction with a ±10% or ±5% tolerance).

[0152] In the exemplary embodiments, the extension in the thickness direction D is substantially 4 mm ± 10%, in particular ± 5%.

[0153] The first connecting element 102 has a first chamber 124.

[0154] The first chamber 124 is arranged in the first housing 106 and opens at or with a first opening 126 in the first access surface 120. The first chamber 124 extends from the first access surface 120 to the opposite side of the first housing 106 into the first curved surface 116 (see Figs. 13 and 14).

[0155] Referring to Fig. 13, at least one reinforcing section, in particular a first and a second reinforcing section 130, 132, is provided on a side wall 128 of the first chamber 124, which reduces an extension of the first chamber 124 with respect to the thickness direction D towards the first curved surface 116.

[0156] The respective reinforcement sections 130, 132 are essentially step-shaped.

[0157] The respective reinforcement sections 130, 132 are each arranged on opposite sides of the side wall 128 of the first chamber 124.

[0158] The first chamber 124 serves as a receiving space for the holding element 108 and the first holding contour 110. In other words, the holding element 108 and the first holding contour 110 are arranged in the first chamber 124. The first chamber 124 can accordingly be a receiving chamber.

[0159] As can be seen in Fig. 1, the holding element 108 can be moved out of the first chamber 124 through the first mouth opening 126, in particular reversibly, in particular in order to be able to engage with the second holding contour 112.

[0160] The second connecting element 104 has a second chamber 134.

[0161] The second chamber 134 is arranged in the second housing 114 and opens at or with a second mouth opening 136 in the second access surface 122.

[0162] The second chamber 134 extends from the second access surface 122 to the opposite side of the second housing 114 into the second curved surface 118 (see Figs. 6 and 8).

[0163] Referring to Fig. 6, at least one reinforcing section, in particular a first and a second reinforcing section 140, 142, is provided on a side wall 138 of the second chamber 134, which reduces an extension of the second chamber 134 with respect to the thickness direction D towards the second curved surface 118.

[0164] The respective reinforcement sections 140, 142 are essentially step-shaped.

[0165] The respective reinforcement sections 140, 142 are each arranged on opposite sides of the side wall 138 of the second chamber 134.

[0166] The second chamber 134 serves as a receiving space for the second holding contour 112. In other words, the second holding contour 112 is arranged in the second chamber 134 and is in particular formed integrally or in one piece with the second housing 114 (together).

[0167] The holding element 108 can be moved out of the first chamber 124, in particular reversibly, through the first mouth opening 126 and can be inserted, in particular reversibly, through the second mouth opening 136 into the second chamber 134 for connecting the first and second connecting elements 102, 104, in particular in order to be able to engage with the second holding contour 112.

[0168] Referring to Figs. 1 and 9 to 15, the first connecting element 102 has a first and a second recess 144, 146.

[0169] The first and second recesses 144, 146 are each arranged at or near an opposite end of the first connecting element 102 with respect to the longitudinal direction L.

[0170] The first and second recesses 144, 146 each extend from the first access surface 120 toward the first curved surface 116, thereby defining first and second counter surfaces 148, 150 on the first connecting element 102. In other words, the first connecting element 102 thereby has one or more first and second counter surfaces 148, 150.

[0171] The first and second counter surfaces 148, 150 are each offset from the first access surface 120. A through hole 152, 154, in particular an elongated hole, is provided in each of the counter surfaces 148, 150.

[0172] In other words, a first through-hole 152, in particular an elongated hole, is provided in the first counter surface 148 and a second through-hole 154, in particular an elongated hole, is provided in the second counter surface 150.

[0173] The respective through holes 152, 154 each extend into the first curved surface 116.

[0174] As can be seen from Fig. 15, the respective through holes 152, 154 each serve to receive an anchoring element 156 for fixing the first connecting element 102 to a groove bottom of a groove provided in one of the components.

[0175] A longitudinal axis of the respective through-hole 152, 154 extends substantially in a radial direction of the first curved surface 116.

[0176] In particular, a first and a second fastening section 158, 160 on the first connecting element 102 can be defined by the first and second recesses 144, 146.

[0177] In other words, the first connecting element 102 has a first and a second fastening section 158, 160, which are each arranged at or near a respective opposite end of the first connecting element 102 with respect to the longitudinal direction L and are set back with respect to the first access surface 120 in the direction of the first curved surface 116.

[0178] The first and second fastening sections 158, 160 each have associated first and second counter surfaces 148, 150, respectively, which are set back from the first access surface 120 and which each have associated first and second through holes 152, 154.

[0179] Referring to Figs. 1 and 2 to 8, the second connecting element 104 has a first and a second recess 162, 164. The first and second recesses 162, 164 are each arranged at or near a respective opposite end of the second connecting element 104 with respect to the longitudinal direction L.

[0180] The first and second recesses 162, 164 each extend from the second access surface 122 toward the second curved surface 118, thereby defining first and second counter surfaces 166, 168 on the second connecting element 104. In other words, the second connecting element 104 thereby has one or more first and one or more second counter surfaces 166, 168.

[0181] The first and second counter surfaces 166, 168 are each offset from the second access surface 122.

[0182] A particularly elongated through hole 170, 172 is provided in each of the counter surfaces 166, 168.

[0183] In other words, a first through-hole 170, in particular in the form of an elongated hole, is provided in the first counter-surface 166, and a second through-hole 172, in particular in the form of an elongated hole, is provided in the second counter-surface 168.

[0184] The respective through holes 170, 172 each extend into the second curved surface 118.

[0185] As can be seen from Fig. 15, the respective through holes 170, 172 each serve to receive an anchoring element 156 for fixing the second connecting element 104 to a groove bottom of a groove provided in one of the components.

[0186] A longitudinal axis of the respective through-hole 170, 172 extends substantially in a radial direction of the first curved surface 116.

[0187] In particular, a first and a second fastening section 174, 176 on the second connecting element 104 can be defined by the first and second recesses 162, 164.

[0188] In other words, the second connecting element 104 has a first and a second fastening section 174, 176, which are each arranged at or near a respective opposite end of the second connecting element 104 with respect to the longitudinal direction L and are set back with respect to the second access surface 122 in the direction of the second curved surface 118.

[0189] The first and second fastening sections 174, 176 each have associated first and second counter surfaces 166, 168, respectively, which are recessed relative to the second access surface 122 and which each have associated first and second through holes 170, 172.

[0190] Adjacent to the respective fastening sections 158, 160, 174, 176 of the first and second connecting elements 102, 104, there is a respective end section 178 which defines a respective end of the first and second connecting elements 102, 104 with respect to the longitudinal axis L. As can be seen from Figs. 1, 3, 10 and 15, the various embodiments of the respective connecting devices 100 differ, for example, in the extension of these end sections 178 with respect to the connecting direction V. The respective end sections 178 of the embodiments of Figs. 1 and 15 extend substantially to planes spanned by the access surfaces 120, 122, and the respective end sections 178 of the embodiment of Figs. 2 to 14 are set back with respect to those planes spanned by the access surfaces 120, 122.

[0191] The respective through-holes 152, 154 of the first connecting element 102 taper from the first curved surface 116 in the direction of the respective counter surface 148, 150 with respect to the longitudinal direction L (cf. Fig. 14), preferably substantially exclusively with respect to the longitudinal direction L.

[0192] The longitudinal axis of the through hole 152, 154 to the connection direction V is arranged at an angle of substantially 18°, whereby in particular assembly tolerances during the introduction of the anchoring elements 156 can be compensated.

[0193] The respective through-holes 170, 172 of the second connecting element 104 taper from the second curved surface 118 in the direction of the respective counter-surface 166, 168 with respect to the longitudinal direction L (cf. Fig. 14), preferably substantially exclusively with respect to the longitudinal direction L. The longitudinal axis of the through-hole 170, 172 to the connecting direction V is arranged at an angle of substantially 18°, whereby in particular assembly tolerances when introducing the anchoring elements 156 can be compensated.

[0194] By means of the anchoring elements 156 which can be inserted at an angle for securing the respective connecting element 102, 104 to one of the components in the through holes 152, 154, 170, 172, an increased pull-out force can be achieved if the anchoring elements 156 are respectively introduced and / or secured in a respective component in a connected state of the components.

[0195] As shown in Fig. 15, the anchoring element 156 can be an anchoring screw. However, it is also conceivable that the anchoring element can be, for example, an anchoring nail.

[0196] 1 to 15, the respective counter surfaces 148, 150, 166, 168 are offset or set back with respect to the access surfaces 120, 122 in such a way that, when the respective anchoring elements 156 in the respective through holes 152, 154, 170, 172 abut the respective counter surface 148, 150, 166, 168 (cf., e.g., Fig. 15), a head 180 of the respective anchoring element 156 does not protrude beyond the access surface 120, 122 with respect to the connection direction V and / or is arranged in particular below a plane spanned by the access surface 120, 122.

[0197] As can be seen in Fig. 15, the head 180 of the respective anchoring element 156 does not protrude beyond one, in particular each, lateral edge of the respective counter surface 148, 150, 166, 168 with respect to the thickness direction D.

[0198] In other words, a head 180 of an anchoring element 156 can be substantially completely received in one of the recesses 144, 146, 162, 164.

[0199] The anchoring element 156 can therefore be arranged on the respective connecting element 102, 104 in such a way that its head 180 does not protrude with respect to side walls with respect to the thickness direction D and the access surface 120, 122 of the respective connecting element 102, 104 or is arranged in particular within these limits.

[0200] In this case, it should be understood that the head 180 of the anchoring element 156 can refer to either a screw head or a nail head (depending on the anchoring element 156). Referring to Figs. 1 to 15, one or more, in the present embodiments four, in particular substantially pyramid-shaped projections 182 are provided on the first and second curved surfaces 116, 118, which protrude from the first and second curved surfaces 116, 118 in a direction facing away from them.

[0201] The projections 182 are arranged in pairs adjacent to the through holes 152, 154, 170, 172.

[0202] Relative to the longitudinal direction L, a projection 182 is arranged on each side of each of the through holes 152, 154, 170, 172.

[0203] In other words, for each through-hole 152, 154, 170, 172, two projections 182 are provided opposite each other with respect to the through-hole 152, 154, 170, 172 with respect to the longitudinal direction L.

[0204] The projections 182 serve to at least partially penetrate into a component to be connected in order to be able to function as a slip protection when anchoring the first and / or the second connecting element 102, 104 by means of at least one anchoring element 156

[0205] The first and second connecting elements 102, 104 further have a plurality of ribs 184.

[0206] In the embodiments shown in Figs. 1 to 14, the first and second connecting elements 102, 104 each have four ribs 184 and in the embodiment shown in Fig. 15, the first and second connecting elements 102, 104 each have six ribs 184.

[0207] The ribs 184 are arranged on respective side walls 186, 188, 190, 192 of the first and second housings 106, 114.

[0208] The first housing 106 has first and second side walls 186, 188, and the second housing 114 has first and second side walls 190, 192, with the first side walls 186, 190 being opposite the second side walls 188, 192. The respective side walls 186, 188, 190, 192 extend transversely to the respective curved surface 116, 118 of the respective connecting element 102, 104.

[0209] Each rib 184 extends along the respective side wall 186, 188, 190, 192 in the connecting direction V.

[0210] Furthermore, each rib 184 projects from the respective side wall 186, 188, 190, 192 in the thickness direction D, wherein each rib 184 projects toward the respective access surface 120, 122 in a continuously increasing manner with respect to the thickness direction D.

[0211] In other words, each rib 184 is substantially wedge-shaped, with its smaller end in the thickness direction facing the respective curved surface 116, 118.

[0212] As can be seen in Figs. 3 and 10, each rib 184 has a tapered extension with respect to the longitudinal direction L, wherein the extension per se refers to a direction from the respective access surface 120, 122 to the respective curved surface 116, 118.

[0213] In other words, each rib 184 is substantially wedge-shaped with respect to the thickness direction D as well as the longitudinal direction L.

[0214] The ribs 184 serve in particular to assist in inserting the respective connecting element 102, 104 into a groove which may be provided in a component to be connected.

[0215] As can be seen in particular in Fig. 13, the first housing 106 has a first section 194 tapered with respect to the thickness direction D.

[0216] This section 194 is arranged in the connecting direction V on a side of the first housing 106 facing away from the first access surface 120.

[0217] This section 194 serves for the targeted insertion of the first connecting element 102 into a groove provided in the component that can be assigned to the first connecting element 102. The taper of the section 194 with respect to the connection direction V is essentially 10°.

[0218] With respect to the tapered portion 194, the first reinforcement portion 130, which is provided in the first chamber 124 of the first connecting element 102, extends from the side of the first housing 106 facing away from the first access surface 120 in an at least partially corresponding manner.

[0219] The first reinforcement section 130 extends substantially parallel along the tapered section 194 with respect to the connecting direction V and has an extension in the connecting direction V that is at least equal to or greater than the tapered section 194.

[0220] In particular, by means of this at least partially corresponding arrangement, a particularly substantially constant wall thickness of a side wall 186, 188 of the first housing 106 can be ensured or a decrease in the wall thickness of a side wall 186, 188 of the first housing 106 can be at least reduced or minimized, respectively, with respect to the thickness direction D.

[0221] As can be seen in particular in Fig. 6, the second housing 114 has a second section 196 which tapers with respect to the thickness direction D.

[0222] This section 196 is arranged in the connecting direction V on a side of the second housing 114 facing away from the second access surface 123.

[0223] This section 196 serves for the targeted insertion of the second connecting element 104 into a groove which is provided in the component which can be assigned to the second connecting element 104.

[0224] The taper of section 196 with respect to the connection direction V is essentially 10°.

[0225] With respect to the tapered portion 196, the second reinforcement portion 132, which is provided in the second chamber 134 of the second connecting element 104, extends from the side of the second housing 114 facing away from the second access surface 122 in an at least partially corresponding manner. The second reinforcement portion 132 extends substantially parallel along the tapered portion 196 with respect to the connecting direction V and has an extension in the connecting direction V that is at least equal to or greater than the tapered portion 196.

[0226] In particular, by means of this at least partially corresponding arrangement, a particularly substantially constant wall thickness of a side wall 190, 192 of the second housing 114 can be ensured or a decrease in the wall thickness of a side wall 190, 192 of the second housing 114 can be at least reduced or minimized, respectively, with respect to the thickness direction D.

[0227] Referring to Figs. 1 to 15, the first connecting element 102 has a first and a second insertion projection 198, 200 which are arranged on the first access surface 120 on opposite sides of the first mouth opening 126 with respect to the longitudinal direction L and project from the first access surface 120.

[0228] The second connecting element 104 has a first and a second receiving pocket 202, 204, which are formed substantially complementary to the first and the second insertion projection 198, 200.

[0229] The first and second receiving pockets 202, 204 are arranged in the second access surface 122 on opposite sides of the second mouth opening 136 with respect to the longitudinal direction L and project back into the second housing 114 from the second access surface 122.

[0230] In the connected state of the connecting elements 102, 104 or the components, the first receiving pocket 202 receives the first insertion projection 198 and the second receiving pocket 204 receives the second insertion projection 200.

[0231] This can, for example, result in the transfer of shear forces by means of the connection between the connecting elements 102, 104 and / or can eliminate the need for additional dowels, which may be required for most other connecting devices.

[0232] The first and second insertion projections 198, 200 are laterally provided with a plurality of ribs and / or grooves defining a rib-groove region 206. The ribs and / or grooves extend substantially along the connection direction V.

[0233] The first and second receiving pockets 202, 204 are also laterally provided with a plurality of grooves and / or ribs which correspond to the plurality of ribs and / or grooves of the insertion projections 198, 200 and accordingly define a corresponding groove-rib region 208.

[0234] The respective ribs and / or grooves or the corresponding regions 206, 208 are configured to be mutually engageable with one another and, in particular, to be mutually engaged when the components are connected.

[0235] As can be seen in particular from Fig. 1 to 15, a rib 184 on the respective side wall 186, 188, 190, 192 of the respective housing 106, 114 is correspondingly assigned to each insertion projection 198, 200 and / or each receiving pocket 202, 204 of the connecting elements 102, 104 and is aligned in a corresponding manner along the connecting direction V.

[0236] As already described, the holding element 108 is configured and serves to connect the first connecting element 102 to the second connecting element 104.

[0237] In particular, the holding element 108 can be moved from a holding position into a release position and / or from the release position into the holding position by means of a mechanical actuating device that can be brought into engagement with the holding element 108 from outside the first connecting element 102.

[0238] In the release position, the holding element 108 is substantially completely received in the first chamber 124 and in the holding position, the holding element 108 is at least partially received in the second chamber 134 in order to be able to engage behind the second holding contour 112 with the first holding contour 110.

[0239] In other words, in the holding position, the second holding contour 112 is at least partially engaged behind by the first holding contour 110, and in the release position, the second holding contour 112 is not engaged behind by the first holding contour 110. To enable the holding element 108 to be actuated, the first housing 106 of the first connecting element 102 is provided with a passage opening 210 for the passage of a mechanical actuating device to the holding element 108.

[0240] In other words, in order to enable the mechanical actuating device to act on the holding element 108, the first housing 106 of the first connecting element 102 comprises a passage opening 210 for the passage of the mechanical actuating device to the holding element 108.

[0241] As can be seen in Figs. 1 and 15, the holding element 108 has a polygonal key receptacle 212 for actuation by means of the mechanical actuating device in the form of a polygonal key. Other receptacles and / or mechanical actuating devices are also conceivable.

[0242] Preferably, the connection of the two connecting elements 102, 104 can be effected by a relative movement of the holding element 108 relative to the first housing 106 of the first connecting element 102 from the release position into the holding position. Furthermore, the connection between the connecting elements 102, 104 can be released again by a movement of the holding element 108 relative to the first housing 106 of the first connecting element 102 from the holding position into the release position.

[0243] Preferably, the connecting elements 102, 104 can be locked against each other by moving the holding element 108 into the holding position, so that the components to be connected can be clamped against each other by tensile forces acting on the connecting elements 102, 104 in the connecting direction V, and thus a completely firm connection can be produced between the components to be connected.

[0244] Referring to the embodiment shown in Fig. 15, the first and second housings 106, 114 each have two recesses in their curved surfaces 116, 118. This can serve, in particular, to save material and make the connecting elements 102, 104 lighter.

[0245] The connecting device 100 and / or in particular each of its connecting elements 102, 104 is respectively configured to cooperate with a mounting device 300, or this mounting device 300 is configured to cooperate with the connecting device 100 and / or in particular each of its connecting elements 102, 104, and is configured to cooperate with the components to be connected. Accordingly, the present invention provides a mounting device 300 for a connecting device 100 for connecting a first component and a second component, in particular for connecting furniture or machine parts.

[0246] In the present case, this connecting device 100 is the connecting device 100 described in connection with Figs. 1 to 15.

[0247] The mounting device according to the invention comprises a base body 302 which extends substantially along a central axis Z.

[0248] The base body 302 is designed to be at least partially complementary and / or corresponding to the connecting device 100 in order to be able to be brought into a particularly positive and / or non-positive engagement with the latter (the connecting device 100) and / or to be able to be inserted into a groove which is provided in one of the components to be connected for at least partially inserting the connecting device 100.

[0249] By means of this mounting device 300, it is particularly possible for at least one processing step to be carried out on one of the components to be connected in preparation for mounting the connecting device 100 therein by means of the mounting device 300 and / or for the connecting device 100 itself to be at least partially mounted in at least one of the components to be connected by means of the mounting device 300.

[0250] The base body 302 has a first, a second and a third section 304, 306, 308.

[0251] The first section 304 is designed at least partially complementary to a first part of the connecting device 100 in order to be able to be brought into a particularly positive and / or non-positive engagement with this part.

[0252] The second section 306 is configured to correspond at least partially to a second part of the connecting device 100 in order to be insertable into a groove provided in one of the components to be connected for at least partial insertion of the connecting device 100, in particular for substantially complete insertion of the second part of the connecting device 100. The first section 304 is arranged at a first end of the base body 302 with respect to the central axis Z.

[0253] The third section 308 is arranged at a second end of the base body 302 with respect to the central axis Z.

[0254] The second section 306 is arranged between the first and third sections 304, 308 with respect to the central axis Z.

[0255] The base body 302 has a center marking 310, which indicates a central mirror plane of the base body 302 and which is arranged on the first section 304.

[0256] The center marking 310 is formed as at least one notch, in this case as four notches aligned with one another with respect to the central axis Z.

[0257] The first section 304 is formed at least partially complementary to one side of the first and second connecting elements 102, 104 of the connecting device 100, wherein that side faces the respective access surface 120, 122 of the respective connecting element 102, 104 of the connecting device 100.

[0258] In other words, the first section 304 is at least partially complementary to both the side of the first connecting element 102 facing the first access surface 120 and the side of the second connecting element 104 facing the second access surface 122.

[0259] As can be seen particularly in Figs. 16 and 17, the first portion 304 has a first and a second projection 312, 314.

[0260] The first and second projections 312, 314 each project substantially in the direction of the central axis Z.

[0261] The first and second projections 312, 314 each have a projection base 316 and an engagement portion 318, wherein the engagement portion 318 extends from the projection base 316 in the direction away from the base body 302. The projection bases 316 are formed substantially complementary to the recesses 144, 146, 162, 164 of the first and second connecting elements 102, 104 in order to be engageable therewith, in particular in a form-fitting and / or force-fitting manner.

[0262] The engagement sections 318 are designed to be substantially complementary to the through holes 152, 154, 170, 172, in particular elongated holes, of the first and second connecting elements 102, 104, in order to be able to be brought into a particularly positive and / or non-positive engagement therewith.

[0263] In other words, the first and second projections 312, 314 can be brought into a particularly positive and / or non-positive engagement with the first and second connecting elements 102, 104 of the connecting device 100, in particular with their through-holes 152, 154, 170, 172, which are provided in the respective connecting element 102, 104 of the connecting device 100.

[0264] Furthermore, the first section 303 has a first and a second recess 320, 322 for receiving the first and the second insertion projection 198, 200 of the first connecting element 102.

[0265] The first section 304 serves in particular to be engageable with the first and / or the second connecting element 102, 104 in order to be able to insert the respective connecting element 102, 104 in a manner plugged onto and / or coupled to the mounting device 300 into a groove in a component to be connected in the direction of the central axis Z and / or the connection direction V, which coincide in this case, in particular purely translationally.

[0266] The second section 306 extends substantially perpendicular to the central axis Z.

[0267] The second section 306 has a curved surface 324 which is circular in shape in a longitudinal section and faces away from the base body 300.

[0268] The second section 306 is formed substantially corresponding to the first and second connecting elements 102, 104 of the connecting device 100.

[0269] In particular, the second section 306 substantially corresponds to an outer contour of the first housing 106 of the first connecting element 102 of the connecting device 100 and / or the outer contour of the second housing 114 of the second connecting element 104 of the connecting device 100.

[0270] The second section 306 therefore preferably has a ratio between an extension in the direction of the central axis Z and an extension perpendicular thereto along the base body 302 of less than or equal to 1 to 9, in particular less than or equal to 1 to 10, preferably less than or equal to 1 to 11.

[0271] For example, this ratio may be between 1 to 9 and 1 to 25, in particular between 1 to 10 and 1 to 25, preferably between 1 to 11 and 1 to 25. It should be understood that the aforementioned ratio values ​​can be considered in the sense of "less than" or "less than or equal to" and / or "greater than" or "greater than or equal to" accordingly.

[0272] For example, the ratio can be essentially 1 to 15.

[0273] The second section 306 has a first, in particular upper, side wall 326, 328 in the direction of the central axis Z and a second, in particular lower, side wall 326, 328 opposite thereto.

[0274] Each of the side walls 326, 328 is provided with a plurality of ribs, in particular crush ribs 330.

[0275] Each of the crush ribs 330 projects substantially in the direction of the central axis Z from the respective side wall 326, 328; that is, substantially downward or substantially upward, respectively.

[0276] Preferably, a thickness tolerance and / or a thickness difference of the groove into which the mounting device 300 can be at least partially inserted and which is provided in one of the components to be connected for at least partial insertion of the connecting device 100 can be compensated by means of the crush ribs 330 when the mounting device 300 is at least partially inserted into the groove.

[0277] The second section 306 further has a first through-bore 332.

[0278] The first through-bore 332 extends from the upper side wall 326 to the lower side wall 328. The first through-bore 332 on the second section 306 is arranged corresponding to the passage opening 210 of the first housing 106 of the first connecting element 102, which serves for the passage of the mechanical actuating device to the holding element 108.

[0279] The third section 308 has a second through-bore 334.

[0280] The second through-hole 334 serves to receive and / or pass through a drilling tool (not shown in the figures).

[0281] At least one drill bushing 340 can be arranged and / or is arranged in the second through-bore 334 of the third section 308, whereby in particular the service life of the mounting device 300 can be extended.

[0282] The second through-bore 334 extends in the direction of the central axis Z and / or substantially perpendicular to the second section 306.

[0283] The second through-bore 334 has an orifice opening 336 facing the second portion 306 and another orifice opening 338 facing the second portion 306.

[0284] The second through-bore 334 of the third section 308 and the first through-bore 332 of the second section 306 each extend along an axis which, due to the substantially aligned arrangement of the through-bores 332, 334, forms a common axis G, as can be seen in Fig. 20.

[0285] The common axis G is oriented essentially parallel to the central axis Z.

[0286] The first through-bore 332 of the second portion 306 is further configured to at least partially receive the drilling tool.

[0287] In other words, the through-bores 332, 334 are arranged relative to one another such that the drilling tool can first be guided through the second through-bore 334 and, after bridging a distance between the third and second sections 308, 306, can be inserted into the first through-bore 332 to at least partially receive the drilling tool therein. The drilling tool can be guided and / or guided in the through-bores 332, 334 along their common axis G.

[0288] In particular, the common axis G of the second through-bore 334 of the third section 308 and the first through-bore 332 of the second section 306 is arranged at a defined position with respect to a component to be connected when the second section 306 of the mounting device 300 is inserted into the groove which is provided in the component to be connected for at least partially inserting the connecting device 100.

[0289] At this defined position with respect to the component in question, when the first connecting element 102 of the connecting device 100 is substantially completely inserted into this groove, a longitudinal axis of the passage opening 210 for the passage of the mechanical actuating device to the holding element 108 is arranged.

[0290] In other words, by means of the drilling tool in conjunction with the assembly direction 300, a bore can be realized in a component to be connected, which bore can be arranged and / or is arranged at the position that substantially corresponds to the position at which the passage opening 210 of the first connecting element 102 can be arranged and / or is arranged correspondingly when the first connecting element 102 is inserted into the said groove.

[0291] The base body 302 further comprises at least one substantially flat stop surface 342 for substantially flush engagement with one of the components to be connected.

[0292] From the stop surface 342, the second section 306 extends substantially perpendicular to the central axis Z.

[0293] In other words, the stop surface 342 extends substantially perpendicular to the second portion 306.

[0294] A plurality of recesses 344 are arranged in the stop surface 342 (in this case six recesses 344).

[0295] A portion of the plurality of recesses 344 is disposed above the second portion 306 with respect to the central axis Z (in this case, three recesses 344), and a portion of the plurality of recesses 344 is disposed below the second portion 306 with respect to the central axis Z (in this case, three recesses 344).

[0296] The recesses 344 serve in particular to receive material, for example chips, which has been cut out of one of the components to be joined by means of a machining step, for example drilling using the drilling tool.

[0297] In other words, the recesses 344 serve, for example, as a chip reservoir.

[0298] As can be seen in Fig. 19, a part of the recesses 344 extend through the entire base body 302 and the remaining recesses 344 extend at least partially through.

[0299] In other words, each of the recesses 344 extends from the stop surface 342 in the direction of a side of the base body 302 facing away from the second section 306, wherein in particular at least a part of the recesses 344 penetrate the base body 302 substantially in this direction, in particular completely.

[0300] As can be seen in particular in Figs. 16 and 19, the third section 308 is provided with a further stop surface 346 which faces away from the base body 302 in the direction of the central axis Z and which serves to stop a depth stop which can be and / or is attached to the drilling tool for defined drilling into a component to be joined.

[0301] Furthermore, the third section 308 is provided with a substantially flat surface inclined to the central axis Z, in other words a substantially flat inclined surface 348, which faces the second section 306.

[0302] The inclined surface 348 forms an angle with the substantially flat stop surface 342.

[0303] In this case, the angle is 45°. Other angles are also possible, e.g., 15°, 30°, 60°, or 75°.

[0304] The base body further comprises one or more pulse receiving surfaces 350 (in this case two pulse receiving surfaces). The pulse receiving surfaces 350 are each arranged between the third and the second section 308, 306.

[0305] The impulse receiving surfaces 350 serve to receive impulses, for example hammer blows, in order to achieve an alignment of the mounting device 300 in connection with a component to be connected and / or to enable and / or force an insertion of a connecting element 102, 104 coupled to the mounting device 300 into a component to be connected.

[0306] Each of the impulse receiving surfaces 350 is at least partially and / or substantially completely oriented in the direction of the central axis Z.

[0307] Each of the impulse receiving surfaces 350 has a surface portion to which the central axis Z is substantially perpendicular and has another surface portion that is angled to the first-mentioned surface portion.

[0308] In this case, the angle is 30°. Other angles are also conceivable, e.g., 15°, 45°, 60°, or 75°.

[0309] Preferably, after the groove has been introduced into the component to be connected, the second section 306 of the mounting device 300 can be inserted into this groove.

[0310] Subsequently, a hole can be drilled in the component to be connected by means of the drilling tool, which can be guided or guided in the through-hole 334 of the third section 308 of the mounting device 300.

[0311] Preferably, a connecting element 102, 104 of the connecting device 100 can then be brought into engagement with the first section 304 of the mounting device 300.

[0312] This connecting element 102, 104 can be inserted into the groove by means of the mounting device 300 along the connecting direction V, which in this case coincides with the direction of the central axis Z.

[0313] In the case of the first connecting element 102, the previously drilled hole and the through-opening 210 of the first connecting element 102 can be substantially aligned in an assembled state. Subsequently, the holding element 108 can be actuated through that hole and the through-opening 210 via the polygonal key receptacle 212 by means of the mechanical actuating device for connecting the first and second connecting elements 102, 104 or the components to be connected.
