DETAILED DESCRIPTION OF THE DRAWINGS

(33) A first embodiment depicted in FIGS. 1 to 12 of a connecting device designated as a whole with 100 serves, for example, for connecting two components 102, in particular furniture parts or machine parts.

(34) The connecting device 100 comprises a main body 104, which in particular is formed as one piece as a plastic injection molded component or as a metal die cast component.

(35) The main body 104 comprises a receiving channel 106 for accommodating a fixing element 108. The receiving channel 106 preferably extends through the main body 104.

(36) An end 110 of the receiving channel 106 preferably forms an insertion opening 112 of the main body 104, by way of which the fixing element 108 may be inserted into the receiving channel 106 of the main body 104.

(37) A further end 114 of the receiving channel 106 preferably forms a fixing opening 116 of the main body 104.

(38) The fixing element 108 is fixable or fixed on and/or in said fixing opening 116, in order to connect the two components 102 to each other.

(39) The insertion opening 112 is preferably of larger dimensions than the fixing opening 116.

(40) In particular, provision is made for the fixing element 108 to be able to be passed entirely through the insertion opening 112, while only a part of the fixing element 108 passes through the fixing opening 116.

(41) In the assembled state of the connecting device 100, the fixing element 108 thus preferably projects only partially out of the fixing opening 116.

(42) On the end 114 of the receiving channel 106 remote from the fixing opening 116, said receiving channel 106 preferably has a tapering section 118.

(43) Said tapering section 118 is preferably engaged from behind by means of the fixing element 108 in order to prevent an undesired pushing out or pulling out of the fixing element 108 through the fixing opening 116.

(44) The fixing element 108 is a screw 120, for example.

(45) A screw head 122 of the screw 120 is preferably dimensioned such that it is does not pass through the tapering section 118, but rather engages it from behind with respect to a connecting direction 124 of the connecting device 100.

(46) A threaded section 126 of the screw 120, however, is preferably dimensioned such that it is able to be passed through the tapering section 118 and thus is able to project out of the fixing opening 116.

(47) The fixing opening 116 is preferably arranged and/or formed in a face side 128 of the main body 104.

(48) The face side 128 is preferably oriented perpendicularly to the connecting direction 124 in the embodiment of the connecting device 100 depicted in FIGS. 1 to 12.

(49) As may be gathered in particular from FIGS. 2 and 3, the receiving channel 106 of the connecting device 100 is formed substantially rotationally symmetrical about a rotational axis 130, for example.

(50) The rotational axis 130 is thereby preferably simultaneously a rotational axis 130, about which the fixing element 108 is rotatable for connecting the two components 102.

(51) In a direction running perpendicularly to the rotational axis 130, the screw head 122 of the fixing element 108 configured as a screw 120 preferably has an outer diameter D.sub.A, which is larger than an inner diameter D.sub.I of the tapering section 118 of the main body 104.

(52) In addition to the insertion opening 112 and the fixing opening 116, the main body 104 preferably comprises an actuating opening 132.

(53) The receiving channel 106 is preferably likewise accessible by way of said actuating opening 132.

(54) Provision is made in particular for the fixing element 108, which is arranged in the receiving channel 106, to be accessible by way of the actuating opening 132.

(55) A tool 134 is preferably able to be brought into engagement with the fixing element 108 through the actuating opening 132, in particular in order to actuate said fixing element 108.

(56) The fixing element 108 preferably has an engagement section 136, on which the tool 134 may engage for actuating the fixing element 108.

(57) The engagement section 136 is an internal hexagonal receiver or internal six-round receiver, for example, on which, for example, a spherical head 138 of the tool 134, formed complementary hereto is able engage.

(58) A may be gathered in particular from FIGS. 3, 11 and 12, the tool 134 for actuating the fixing element 108 is rotatable about an engagement axis 140 oriented obliquely to the rotational axis 130.

(59) For example, an angle α (alpha) of about 30° between the rotational axis 130 and the engagement axis 140 may hereby be provided.

(60) The tool 134 is thus in particular able to be passed obliquely through the actuating opening 132.

(61) The actuating opening 132 is therefore preferably configured as an actuating slot 142.

(62) The spherical head 138 and the engagement section 136 preferably form an angular gear 144, with which the rotational movement of the tool 134 is transmittable to the fixing element 108.

(63) For anchoring the main body 104 in a component 102, the main body 104 preferably has a base section 146 and one or more anchoring sections 148 protruding or projecting from the base section 146.

(64) An anchoring section 148 may, for example, be configured as a cylindrical thickening 150 of the end 110 of the main body 104 remote from the face side 128.

(65) The one or more anchoring sections 148 project in particular away from the base section 146 in one or more directions running perpendicularly to the connecting direction 124, such that the main body 104 is fixable in particular in a positive-fitting manner in a recess 152 in a component 102, said recess formed complementary to the main body 104 (see in particular FIGS. 8 and 9).

(66) As may be gathered in particular from FIG. 8, the recess 152 is preferably arranged and/or formed in a component 102 in such a way that the recess 152 extends both in a main side 154 and in a narrow side 156 of the component 102. The orientation of the recess 152 is thereby preferably selected such that the connecting direction 124 is oriented at least approximately perpendicularly to the narrow side 156.

(67) As is indicated by a comparison of FIGS. 8 and 9, the recess 152 and the main body 104 are preferably formed complementary to each other, such that the recess 152 is substantially entirely fillable by means of the main body 104.

(68) An outer side 158 of the main body 104 remote from the receiving channel 106 is preferably provided with one or more anchoring ribs 160.

(69) The anchoring ribs 160 are in particular linear barbs, which enable the insertion of the main body 104 into the recess 152, but which inhibit a removal of the main body 104 from the recess 152.

(70) A may be gathered in particular from FIG. 7, provision may be made for the tapering section 118 of the main body 104 to comprise one or more retaining projections 162, for example retaining ribs 164.

(71) By means of said retaining projections 162, the inner diameter D.sub.I of the tapering section 118 is locally reduced, such that in particular a threaded section 126 of a fixing element 108 configured as a screw 120 is able to be accommodated in the tapering section 118 in a clamping or latching manner.

(72) The fixing element 108 may hereby be held on the main body 104 and in particular be secured against undesirably falling out of the main body 104.

(73) The embodiment of a connecting device 100 described above functions in particular as follows:

(74) Two components 102 to be connected to each other are preferably prepared in that a recess 152 is introduced into a first component 102a (see in particular FIG. 8).

(75) The shape of the recess 152 is in particular formed complementary to the shape of the main body 104 of the connecting device 100, such that the main body 104 is fixable in the recess 152 in particular in a positive-fitting manner.

(76) The positive fit thereby relates in particular to a connecting direction 124, in which a force which later connects the two components 102 acts.

(77) The recess 152 is introduced into the first component 102a by means of a milling machine, for example.

(78) A second component 102b is provided with a bore 166, for example (see in particular FIG. 11).

(79) The connecting device 100 is prepared for the assembly thereof and of the components 102 preferably in that the fixing element 108, configured for example as a screw 120, is inserted into the receiving channel 106 of the main body 104 by way of the insertion opening 112.

(80) The fixing element 108 is thereby in particular pushed so far through the receiving channel 106 until the fixing element 108 comes into engagement with the retaining projections 162 and is thereby securely held on the main body 104.

(81) The main body 104 is then inserted together with the fixing element 108 into the recess 152 of the first component 102a.

(82) The two components 102 are then arranged in the desired position to be fixed by means of the connecting device 100.

(83) In particular, a threaded section 126 of the fixing element 108 configured as a screw 120, which projects out of the fixing opening 116, may thereby already be partially inserted into the bore 166 of the second component 102b.

(84) In a next step, the tool 134 is passed through the actuating opening 132 and brought into engagement with the engagement section 136 of the fixing element 108.

(85) The fixing element 108 may be put into rotation by rotating the tool 134.

(86) In particular, the fixing element 108 is thereby screwed into the bore 166 of the second component 102b.

(87) The two components 102 are tightly connected to each other as a result.

(88) A force transmission along the connecting direction 124 then occurs, on the one hand, between the second component 102b and the threaded section 126 of the fixing element 108 configured as a screw and, on the other hand, between the anchoring section 148 of the main body 104 and the recess 152 in the first component 102a.

(89) The force transmission between the main body and the fixing element 108 occurs between the screw head 122 and the tapering section 118.

(90) By appropriately designing the anchoring section 148, even large forces may preferably be transferred from the first component 102 or to the first component 102, without having to fear an undesired pulling out of the recess 152 in the region of the narrow side 156.

(91) In particular, it may be achieved by way of the arrangement of the anchoring section 148 or the anchoring sections 148 on the end 110 of the main body 104 remote from the fixing opening 116 that the forces acting on the first component 102a are transmitted at a great distance from the narrow side 156.

(92) A second embodiment of a connecting device 100 depicted in FIGS. 13 and 14 differs from the first embodiment depicted in FIGS. 1 to 12 substantially in that the face side 128 of the main body 104 is oriented obliquely to the connecting direction 124.

(93) The connecting device 100 in accordance with the second embodiment depicted in FIGS. 13 and 14 is suited in particular for connecting two mitered components 102.

(94) In particular, the face side 128 of the main body 104 is oriented tilted by 45° to the connection 124, such that the connecting device 100 is suited in particular for connecting two components 102 to be arranged at a 90° angle to each other if said components 102 are each provided with a 45° miter.

(95) In all other respects, the second embodiment of the connecting device 100 depicted in FIGS. 13 and 14 corresponds with respect to construction and function to the first embodiment depicted in FIGS. 1 to 12, such that reference is made to its preceding description in that regard.

(96) A third embodiment of a connecting device 100 depicted in FIGS. 15 to 18 differs from the first embodiment depicted in FIGS. 1 to 12 substantially in that the main body 104 has an anchoring bolt 168 in place of the cylindrical thickening 150.

(97) The anchoring bolt 168 extends in particular away from the base section 146 of the main body 104 perpendicularly to a main side 154 of the first component 102a in which the main body 104 is fixable.

(98) The anchoring bolt 168 is preferably arranged on the end 110 of the main body 104 remote from the fixing opening 116.

(99) Further, in the third embodiment of the connecting device 100 depicted in FIGS. 15 to 18, provision is made for the main body 104 to comprise one or more, for example four, positioning projections 170.

(100) The positioning projections 170 are in particular arranged on the face side 128 of the main body 104 and form, for example, an annular expansion of the fixing opening 116 and/or the tapering section 118.

(101) The positioning projections 170 serve in particular for positioning the main body 104 in the second component 102b relative to a bore 166, independently of the fixing element 108, whereby, when orienting the components 102 relative to each other, the positioning projections 170 are already inserted into the bore 166 of the second component 102b before the fixing of the fixing element 108.

(102) In all other respects, the third embodiment of the connecting device 100 depicted in FIGS. 15 to 18 corresponds with respect to construction and function to the first embodiment depicted in FIGS. 1 to 12, such that reference is made to its preceding description in that regard.

(103) Optional counter pieces 172 of the connecting device 100 are depicted in FIGS. 19 to 23.

(104) The depicted counter pieces 172 are used in particular individually in combination with a main body 104 and a fixing element 108 if the fixing element 108 is, for whatever reason, not to be fixed directly on the second component 102b.

(105) In these cases, one of the counter pieces 172 or a not-depicted counter piece 172 is fixed, for example screwed, latched, bonded, etc., on the second component 102b.

(106) The fixing element 108 then does not engage directly on the second component 102b in order to connect the two components 102. Rather, the fixing element 108 is then preferably brought into engagement with the counter piece 172 in and/or on the second component 102b.

(107) The counter piece 172 may thereby be, for example, an insertion plate (see FIG. 19), a drive-in bushing (see FIG. 20), an insert bushing (see FIG. 21), a drive-in nut (see FIG. 22), or a glue-in nut (see FIG. 23).

(108) A fourth embodiment of a connecting device 100 depicted in FIGS. 24 to 29 differs from the first embodiment depicted in FIGS. 1 to 12 substantially in that two spreading elements 200 of a spreading device 201 are provided.

(109) The spreading elements 200 are in particular pivoting elements 202, which are formed as one piece with the main body 104 and are fixed on the main body 104 so as to be moveable, in particular pivotable, with respect to the receiving channel 106.

(110) As is indicated in particular by a comparison of FIGS. 24 and 25, the spreading elements 200 are in particular arrangeable, on the one hand, in the initial position depicted in FIG. 24 and, on the other hand, in the spread position depicted in FIG. 25.

(111) In the initial position, the spreading elements 200 project in particular into the receiving channel 106 (see in particular FIG. 28). In the spread position, however, the spreading elements 200 are moved outwardly out of the receiving channel 106 by means of the screw head 122 of the fixing element 108 configured as a screw 120. In the spread position, the spreading elements 200 thus project over an outer contour of the main body 104.

(112) In the assembled state of the connecting device 100 in a component 102, the spreading elements 200 are pressed into the component 102 by means of the fixing element 108.

(113) As a result, in particular a stable clamping and/or anchoring fixing of the main body 104 in the component 102 may be achieved.

(114) The spreading elements 200 are formed, for example, by C-shaped recesses 204 in side walls 206 of the main body 104.

(115) In particular, C-shaped separating slots 208 are provided in the main body 104 in order to form the spreading elements 200.

(116) As may be gathered in particular from FIG. 29, the spreading elements 200 preferably each comprise one or more oblique faces 210, on which the fixing element 108, in particular the screw head 122, engages in order to bring the spreading elements 200 from the initial position into the spread position.

(117) The spreading elements 200 are preferably formed and/or arranged to be elastically resilient.

(118) If the fixing element 108 is removed from the fixing opening 116, the spreading elements 200 thus preferably automatically move from the spread position back into the initial position.

(119) In all other respects, the fourth embodiment of the connecting device 100 depicted in FIGS. 24 to 29 corresponds with respect to construction and function to the first embodiment depicted in FIGS. 1 to 12, such that reference is made to its preceding description in that regard.

(120) A fifth embodiment of a connecting device 100 depicted in FIG. 30 differs from the first embodiment depicted in FIGS. 1 to 12 substantially in that the connecting device 100 comprises multiple, for example three or four, anchoring sections 148, which in particular are configured as at least sectionally cylindrical thickenings 150.

(121) The anchoring sections 148 preferably overlap each other in such a way that the main body 104 in a cross section is cloud-shaped, for example.

(122) Anchoring ribs 160 are not provided in the fifth embodiment of the connecting device 100 depicted in FIG. 30. However, in a further (not depicted) embodiment, the cloud shape depicted in FIG. 30 may indeed be provided in combination with anchoring ribs 160.

(123) In all other respects, the fifth embodiment of the connecting device 100 depicted in FIG. 30 corresponds with respect to construction and function to the first embodiment depicted in FIGS. 1 to 12, such that reference is made to its preceding description in that respect.

(124) A sixth embodiment of a connecting device 100 depicted in FIG. 31 differs from the fifth embodiment depicted in FIG. 30 substantially in that the main body 104 is provided with anchoring ribs 160.

(125) In addition, the main body 104 comprises a covering section 212, by means of which in particular a rim of the recess 152 in a component 102 is coverable.

(126) The covering section 212 is configured in particular as a laterally projecting collar 214 on the main body 104.

(127) The covering section 212, in particular the collar 214, has in particular a geometrically simpler shape than the anchoring sections 148 of the main body 104, whereby in particular an aesthetic appearance of the connecting device 100 in the assembled state thereof may be achieved.

(128) Further, in the embodiment of the connecting device 100 depicted in FIG. 31, provision is made for the actuating opening 132 to be formed at least in sections and/or at least approximately complementary to an outer contour of the fixing element 108.

(129) In particular, the actuating opening 132 comprises a narrow slot section 216 and a section 218 that is wider in comparison hereto.

(130) The slot section 216 and the wider section 218 are in particular formed such that a fixing element 108 configured as a screw 120 is insertible into the receiving channel 106 through the actuating opening 132.

(131) The insertion opening 112 is thus optional in the sixth embodiment of the connecting device 100 depicted in FIG. 31.

(132) In all other respects, the sixth embodiment of the connecting device 100 depicted in FIG. 31 corresponds with respect to construction and function to the fifth embodiment depicted in FIG. 30, such that reference is made to its preceding description in this regard.

(133) In further (not depicted) embodiments of connecting device 100, individual or multiple features of the embodiments described above may be combined with each other in any way.

(134) For example, an obliquely oriented face side 128 in accordance with the second embodiment depicted in FIGS. 13 and 14 may also be provided in the third embodiment of the connecting device 100 depicted in FIGS. 15 to 18. Further, a collar 214 and/or covering section 212 for covering a rim region of the recess 152 arranged in the component 102 may, for example, also be provided in the embodiment of the connecting device 100 depicted in FIGS. 1 to 12.
