Provision may be made for the connecting device to comprise at least one locking element and at least one actuating element for actuating the at least one locking element, wherein the at least one locking element and the at least one actuating element are preferably arranged on mutually differing parts and/or connecting elements.
Hereby, actuation is to be understood in particular as meaning the movement of the at least one locking element into a retaining position for the connection of the two parts and/or into a release position for the release and removal of the parts from each other.
The locking element can, for example, be a retaining element.
However, as an alternative or in addition thereto, provision could also be made for at least one locking element to be an element differing from a retaining element.

For the purposes of producing advantageous embodiments of the invention, particular ones or several of the features described in this description and the accompanying Claims can be utilised or omitted at will in combination with further features or independently of further features.
Further preferred features and/or advantages of the present invention form the subject matter of the following description and the graphical illustration of exemplary embodiments.
Similar or functionally equivalent elements are provided with the same reference symbols in all the Figures.
A connecting device designated as a whole by 100 serves, for example, for connecting a first substantially plate-like part 102 to a second likewise substantially plate-like part 104 (see
The two parts 102 and 104 consist of wood or plywood for example, but could consist of any other materials such as a metallic material or a plastic material (e.g. Plexiglas) for example.
Furthermore, provision may be made for the first part 102 and the second part 104 to consist of mutually different materials.
In the connected state of the two parts 102 and 104, a contact surface 106 of the first part 102 which forms a narrow side of the first part 102 abuts on a contact surface 108 of the second part 104 which forms a major face of the second part 104.
A respective groove 110, which is formed in the related part 102 or 104, opens out into each of the contact surfaces 106, 108 and comprises a base section 112 in the form of a segment of a circular cylinder or a section of a circular cylinder and two undercut sections 114 which extend away from the base section 112 in a thickness direction 116. The radius of curvature of the base section 112 is larger than the groove depth T (see
The base section 112 of the groove 110 has a width B of approximately 8 mm for example in the thickness direction 116.
Each of the undercut sections 114 of the groove 110 is bounded on the side thereof remote from the respective contact surface 106 and 108 by a bottom surface 120 which is flush with the bottom surface of the groove 118 and is in the form of a section of the surface of a circular cylinder and has the same radius of curvature as the bottom surface of the groove 118 of the base section 112.
In the direction toward the contact surface 106 or 108, each undercut section 114 is bounded by an undercut surface 122 which is likewise in the form of a section of the surface of a circular cylinder and is concentric with the bottom surface 120 and has a smaller radius of curvature.
Each of the undercut sections 114 is bounded laterally by a lateral boundary surface 124 which runs perpendicularly to the respective contact surface 106 and 108.
The width b, i.e. the extent thereof in the thickness direction 116, amounts to approximately 1 mm for example for each of the undercut sections 114.
The height h, i.e. the distance between the bottom surface 120 and the undercut surface 122, amounts to approximately 2 mm for example for each of the undercut sections 114.
The base section 112 of each groove 110 is bounded by lateral boundary walls 126 which run substantially perpendicularly to the respective contact surface 106 and 108 and they are spaced from each other by the groove width B.
As can be seen from
In order to produce the previously described grooves 110 in the parts 102 and 104, the groove milling device described in EP 1 990 549 A1 for example can be used.
For the purposes of connecting the parts 102, 104 to one another, one or more grooves 110 and in particular grooves 110 of the type described hereinabove can be provided in each of the parts 102, 104.
However, provision could also be made for just one of the parts 102, 104 to be provided with one or more grooves 110 and in particular grooves 110 of the previously mentioned type, whereas the further part 104, 102 has no groove 110 of the previously described type, or has a differently formed groove 110, one or more borings, one or more recesses, one or more projections and/or one or more cut-outs, or is in its original state.
Various embodiments of connecting devices 100 for connecting different parts 102, 104 and in particular differently prepared parts 102, 104, are described in the following.
A first embodiment of a connecting device 100 that is illustrated in
A connecting element 130 which is insertable into a groove 110 is preferably to be understood as being a connecting element 130 that is insertable into a groove 110 which comprises a base section 112 and one or more undercut sections 114 that extend away from the base section 112 in a thickness direction 116. The one undercut section 114 or the plurality of undercut sections 114 preferably comprise one or more undercut surfaces 122 which are formed and arranged concentrically to the base section 112. In particular hereby, the undercut surface 122 or the undercut surfaces 122 is or are in the form of a section of the surface of a circular cylinder.
A connecting element 130 that is insertable into a groove 110 preferably comprises a main body 134 which comprises a main body 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.
The retaining projections 138 each have a curved supporting surface 140 which is in the form of an arc of a circle in longitudinal section.
In particular, the retaining projections 138 are formed such as to be non-self-cutting.
In this description and the accompanying Claims, a longitudinal section, a longitudinal direction, etc. is to be understood as a section or a movement of the connecting element 130 in a plane in which a path of movement of the connecting element 130 lies when it is being pushed into a groove 110.
In particular, a longitudinal section is a section taken perpendicularly with respect to an axis of symmetry of the supporting surfaces 140 of the connecting element 130.
A cross section is to be understood in particular, as a section taken perpendicularly with respect to a longitudinal section, for example, a section taken perpendicularly with respect to a contact surface 106, 108 and parallel to the axis of symmetry of the supporting surfaces 140 of the connecting element 130.
Preferably, a cross section is a section along a plane in which the axis of symmetry of the supporting surfaces 140 of the connecting element 130 extends.
In the first embodiment of the connecting device 100 that is illustrated in
In particular, the retaining element 142 is arranged on the main body 134 such as to be rotatable about a rotational axis 144 running parallel to the thickness direction 116.
As can be perceived from
In particular, an engagement section 148 of the connecting element 130 in the form of a screw element 132 is engageable by means of the engagement projections 146 and is able to be drawn thereby towards the rotational axis 144.
The connecting element 130 in the form of a screw element 132 also comprises a stop 150 beside the engagement section 148.
The screw element 132 is fixable to one of the parts 102, 104 in a correct position in a reliable manner by means of the stop 150.
In particular, it can be ensured by means of the stop 150 that, in the installed state of the screw element 132 on one of the parts 102, 104, the engagement section 148 protrudes sufficiently far above a contact surface 106, 108 of the part 102, 104 as to be brought into engagement with the retaining element 142.
In the installed state of the connecting element 130 that is insertable into the groove 110, the contact surfaces 106, 108 of the part 102, 104 and a bearing surface 152 of the connecting element 130 are preferably substantially flush.
The connecting element 130 is preferably screwable to the part 102, 104 in which the groove 110 is arranged. To this end, the main body 134 of the connecting element 130 comprises two through openings 154 that serve for the purposes of feeding (not illustrated) screws therethrough. In addition, the through openings 154 are provided with recesses 156 in order to enable (not illustrated) screw heads to be accommodated within an outer contour of the main body 134.
The connection between the parts 102, 104 by means of the connecting device 100 is established as follows:
Firstly, the connecting element 130 in the form of a screw element 132 is screwed into one of the parts 102, 104 until the stop 150 of the screw element 132 abuts on the contact surface 106, 108.
The further part 104, 102 is then provided with a groove 110 and in particular with one of the grooves 110 illustrated in
Thereupon, the connecting element 130 that is insertable into the groove 110 is inserted into the groove 110 and fixed to the part 102, 104 by means of the (not illustrated) screws. In the installed state of the connecting element 130 that is insertable into the groove 110, the retaining element 142 is accessible through a cylindrical access boring 128 which was previously produced in the part 102, 104.
In a next step, the parts 102, 104 are laid on one another in such a way that the engagement section 148 of the screw element 132 enters a seating opening 158 corresponding thereto in the main body 134 of the connecting element 130.
The parts 102, 104 then abut one another at their contact surfaces 106, 108.
For the purposes of fixing the parts 102, 104 relative to each other, the retaining element 142 then only has to be moved from the initially set release position into a retaining position.
To this end, a (not illustrated) wrench is brought into engagement with a wrench seating 160 of the retaining element 142 through the access boring 128. The retaining element 142 is then moved from the release position into the retaining position by rotating the wrench and thus too the retaining element 142 about the rotational axis 144.
The engagement projections 146 thereby engage behind the engagement section 148 of the screw element 132 and draw it towards the rotational axis 144.
A pulling effect is thereby exerted on the parts 102, 104 so that they are firmly connected to one another.
The connecting element 130 in the form of a screw element 132 preferably has a substantially rotationally symmetrical engagement section 148. In this way, the screw element 132 can always be gripped reliably by means of the retaining element 142 independently of the rotational orientation.
The anchoring of the connecting element 130 which comprises the engagement section 148 can be effected on the one hand by means of the illustrated screw. However, as an alternative thereto, bolt-like pressure, an adhesive, screwing-in by means of a Spax thread or a metric thread, fixing by means of a dowel pin, riveting and/or welding an element which comprises the engagement section 148 could also be envisaged for the process of fixing to the one part 102, 104.
A second embodiment of a connecting device 100 that is illustrated in
In particular, this parallelepipedal connecting element 130 is screwable onto a contact surface 108 of a part 104 by means of two screws 162.
The parallelepipedal connecting element 130 comprises two engagement projections 146 and a substantially semi-circular engagement channel 164.
The connecting element 130 that is introducible into the groove 110 comprises a retaining element 142 which has an at least partly substantially T-shaped cross section and thus comprises an engagement section 148.
In particular, the retaining element 142 is introducible into the engagement channel 164 of the parallelepipedal connecting element 130 and is adapted to be brought into engagement therewith by means of the engagement projections 146 by a rotary movement.
Furthermore, the connecting element 130 that is introducible into the groove 110 comprises two plug-in projections 166 which are insertable into seating pockets 168 corresponding thereto in the parallelepipedal connecting element 130.
The plug-in projections 166 and the seating pockets 168 preferably have a ribbed or undulating surface in order to prevent a displacement of the plug-in projections 166 within the seating pockets 168.
As can be perceived from
The bearing surface 152 of the main body 134 of the connecting element 130 is set back relative to the contact surface 106 of the part 102 in the installed state of the connecting element 130 in the groove 110.
The contact surfaces 106, 108 thereof abut each other in the connected state of the parts 102, 104
The parallelepipedal connecting element 130 that is screwed tightly to the contact surface 108 of the second part 104 then extends into the groove 110 in the first part 102.
Reliable fixing of the parts 102, 104 relative to each other with reference to the thickness direction 116 can thus be obtained merely by pushing the parallelepipedal connecting element 130 into the groove 110 in the first part 102.
By rotating the retaining element 142 by means of the (not illustrated) wrench, the retaining element 142 can be brought into the retaining position in which the engagement section 148 engages behind the engagement projections 146 and the connecting elements 130 as well as the parts 102, 104 define a direction of connection 170 that is oriented perpendicularly to the contact surfaces 106, 108.
In all other respects, the second embodiment of the connecting device 100 that is illustrated in
A third embodiment of a connecting device 100 that is illustrated in
This screw element 132 is screwable into one of the parts 102, 104.
A parallelepipedal section 172 of the screw element 132 comprises an engagement channel 164 and two engagement projections 146.
Thus, in a similar way to the second embodiment illustrated in
In all other respects, the third embodiment of the connecting device 100 that is illustrated in
A fourth embodiment of a connecting device 100 that is illustrated in
Hereby, the grooves 110 in each part 102, 104 are arranged to overlap so that the bottom surfaces 118 of the grooves 110 intersect or border one another within the respective part 102, 104 underneath the contact surface 106, 108.
In the fourth embodiment of the connecting device 100 that is illustrated in
On the one hand, there are provided connecting elements 130 each of which comprises two suspension elements 174.
Furthermore, there are provided connecting elements 130 which each comprise two suspension element seatings 176.
Both the suspension elements 174 and the suspension element seatings 176 each comprise at least one inclined surface 178 which is inclined to the bearing surface 152 and/or inclined to the contact surface 106, 108.
Furthermore, all of the connecting elements 130 comprise a respective securing projection 180 and a securing seating 182.
A securing device 184 is formed by means of the securing projection 180 and the securing seating 182. The securing device 184 serves, in particular, for fixing at least one of the connecting elements 130 in the groove 110 and in particular for preventing unwanted displacement of the connecting element 130 within the groove 110.
To this end, a securing projection 180 of a connecting element 130 is moveable into engagement with a securing seating 182 of a further connecting element 130 (see in particular,
A securing projection 180 and a securing seating 182 of a connecting element 130 are preferably arranged at mutually opposite end regions 186 of the main body 134 and in particular, the supporting surfaces 140.
As can be perceived from
By introducing a securing element and in particular a securing pin into the through openings 188, the connecting elements 130 and thus too the parts 102, 104 can be secured from unwanted displacement thereof relative to each other.
As can be perceived from
Thereafter, the parts 102, 104 and the connecting elements 130 arranged therein are displaced in parallel with the contact surfaces 106, 108. The inclined surfaces 178 of the suspension elements 174 and the suspension element seatings 176 thereby come into engagement with one another so that the connecting elements 130 and thus too the parts 102, 104 are pulled towards one another.
The fourth embodiment of the connecting device 100 that is illustrated in
In all other respects, the embodiment of a connecting device 100 that is illustrated in
A fifth embodiment of a connecting device 100 that is illustrated in
In addition in the case of the embodiment of the connecting device 100 that is illustrated in
In particular, the magnet element 190 is an element that is operable magnetically by means of a (not illustrated) magnet device.
The magnet element 190 is movable linearly to and fro by means of the magnet device for example.
The retaining element 142 preferably comprises a seating 192 for the magnet element 190.
One of the connecting elements 130 preferably serves for accommodating the retaining element 142 together with the magnet element 190 that is accommodated therein.
To this end in particular, this connecting element 130 comprises a substantially slot-like guide 194 in the main body 134.
The retaining element 142 is movable along the slot-like guide 194 relative to the main body 134.
Furthermore, the retaining element 142 has two inclined surfaces 178 which are moveable into engagement with engagement projections 146 in the further connecting element 130.
The inclined surfaces 178 of the retaining element 142 thus form an engagement section 148 of the retaining element 142.
As can be perceived from
When connecting the connecting elements 130 to one another, the plug-in projections 166 are firstly inserted into the seating pockets 168.
The engagement section 148, in particular the inclined surfaces 178, is moved simultaneously behind the engagement projections 146 with reference to the direction of connection 170.
Finally, the bearing surfaces 152 of the connecting elements 130 as well as the contact surfaces 106, 108 of the parts 102, 104 come to abut on one another.
In a next step, the magnet element 190 is then actuated for fixing the connecting elements 130 and hence the parts 102, 104 relative to each other along the direction of connection 170.
To this end, the magnet device is brought into the proximity of the connecting device 100 and the magnet element 190 is accelerated within the seating 192.
The magnet element 190 is thereby accelerated, in particular, repeatedly, within the seating 192 and is braked by striking an end region of the seating 192.
Hereby, the seating 192 is bounded at one end by a locking surface 196 and at the other end by an unlocking surface 198.
The retaining element 142 is brought into the retaining position in which the engagement section 148 of the retaining element 142 engages behind the engagement projections 146 due to an impact of the magnet element 190 on the locking surface 196.
The retaining element 142 is moved in the opposite direction and hence the engagement section 148 is disengaged from the engagement projections 146 due to the magnet element 190 striking the unlocking surface 198.
The retaining element 142 can thus be moved selectively into the retaining position or into the release position.
A displacement of the main bodies 134 of the connecting elements 130 relative to each other due to the magnet element 190 striking the locking surface 196 or the unlocking surface 198 is preferably prevented by means of the plug-in projections 166 and the seating pockets 168.

The retaining element 142 and the magnet element 190 are arranged on a main body 134 of a connecting element 130 that is introducible into a groove 110.
A further connecting element 130 which is likewise preferably introducible into a groove 110 preferably comprises a seating 200 for the retaining element 142 in the form of a screw.
In particular, the seating 200 is a threaded nut.
The seating 200 is preferably arranged such as to be moveable, particularly in spring-like manner, on a main body 134 of the further connecting element 130. To this end in particular, two spring elements 202 are provided on the main body 134.
The main bodies 134 of the connecting elements 130 preferably comprise a respective cover element 204 by means of which an interior space 206 of the respective main body 134 is closable.
In particular, the seating 200, the magnet element 190 and/or the retaining element 142 in the form of a screw are accessible and/or removable from the respective main body 134 by removing the respective cover element 204.
As can be perceived from
In regard to the type of actuation of the retaining element 142 by means of the magnet element 190 as well as in regard to the actuation of the magnet element 190 by means of the magnet device, reference is made to WO 99/43961 A1 the contents of which are hereby incorporated by reference in this description.

In particular, the tongue-and-groove device 224 is formed by a groove part 226 and a tongue part 228.
Here, the groove part 226 and the tongue part 228 are arranged and/or formed on mutually differing connecting elements 130.
As can be perceived from
The tongue-and-groove device 224 thereby serves, in particular, for adhesive-free anchoring of the one part 102 on the other part 104.
Hereby, the tongue-and-groove device 224 preferably functions in a similar manner to the interlocking process for the flooring elements of a click-together parquet flooring or a click-together laminate flooring.

Connecting elements 130 in the form of screw elements 132 are fixable in positive-locking and/or force-locking manner in the screw seatings 230 in releasable manner.
For the purposes of anchoring the connecting element 130 in the part 102 in which the groove 110 is arranged, the connecting element 130 comprises a through opening 154 corresponding to that in the first embodiment of the connecting device 100 that is illustrated in
In the tenth embodiment of the connecting device 100 that is illustrated in
The connecting element 130 that is insertable into the groove 110 and in particular the screw seatings 230 are thus accessible from a side 234 of the second part 104 that is remote from the first part 102.
The second part 104 can thus be clamped and/or mounted firmly between the screw heads 236 of the screw elements 132 and the connecting element 130 that is insertable into the groove by screwing the screw elements 132 to the connecting element 130 that is insertable into the groove 110.
The screw seatings 230 are threaded borings or elongate holes with an internal thread for example. As an alternative thereto, provision may be made for the screw seatings 230 to be yielding seatings for self-tapping screws.
The screw seatings 230 for the self-tapping screws are preferably seatings in the form of elongate holes.

Hereby, a guidance device 238 is formed by means of the connecting device 100 and the parts 102, 104 are guided in movable manner relative to each other by means of said guidance device.
Hereby, the connecting device 100 comprises at least one connecting element 130 which is a connecting element 130 that is insertable into a groove 110
This connecting element 130 preferably comprises a guidance element 240, a guidance projection 242 for example which, in the installed state of the connecting element 130, projects above the bearing surface 152 of the main body 134 of the connecting element 130 and above the contact surface 106 of the part 102 in which the connecting element 130 is arranged.
Here for example, the guidance element 240 is substantially in the form of a parallelepiped.
The further part 104 preferably comprises a guidance groove 244 for accommodating the guidance element 240.
Hereby for example, the guidance groove 244 is integrated into a connecting element 130 or into the part 104 itself.
In the eleventh embodiment of the connecting device 100 that is illustrated in

In particular, the bearing elements 246 are in the form of roller elements 248.
For example, two pairs of roller elements 248 are provided.
In the twelfth embodiment of the connecting device 100 that is illustrated in
Hereby, the guidance groove 244 preferably comprises a guidance section 250 in which the guidance element 240 and in particular the bearing elements 246 of the guidance element 240 can engage behind the guidance groove 244.
With respect to the direction of the force of gravity g for example, the guidance groove 244 is open downwardly so that the connecting element 130 comprising the guidance element 240 together with the part 102 on which the connecting element 130 is arranged can be suspended in the guidance groove 244.
Such a connecting device 100 can then be used in particular, as a suspension for a sliding door.
In all other respects, the twelfth embodiment of a connecting device 100 that is illustrated in
A thirteenth embodiment of a connecting device 100 that is illustrated in
This connecting element 130 too is preferably insertable into a groove 110.
The bearing element 246 preferably projects above the bearing surface 152 of the main body 134 and above a contact surface 106 of the part 102 in which the connecting element 130 is arranged.
In particular, the bearing element 246 in the form of a roller element 248 is mounted on the main body 134 in rotary manner and can roll on a running surface 252 for example.
The running surface 252 is, for example, arranged on a further part 104 or is formed by the further part 104.
The running surface 252 can thus form a connecting element 130 of the connecting device 100 for example.
It can be advantageous for the running surface 252 to be formed by a contact surface 108 of the further part 104.
In the installed state of the connecting device 100 and the parts 102, 104, the bearing element 246 preferably abuts on the running surface 252 and is movable along the running surface 252. Consequently, the parts 102, 104 are also movable relative to each other.

In addition, no fixed plug-in projections 166 are provided in the embodiment of the connecting device 100 that is illustrated in
Rathermore, the connecting device 100 comprises a positioning device 254 for positioning the parts 102, 104 and in particular, the connecting elements 130 relative to each other.
The positioning device 254 comprises one or more positioning elements 256 and one or more positioning element seatings 258.
The positioning elements 256 are preferably mounted in moveable, yielding, resilient and/or spring-like manner.
In the embodiment of a connecting device 100 that is illustrated in
In addition, a spring element 264 and a closure element 266 such as a set-screw 268 for example are arranged in each of the through openings 262.
The at least one through opening 262 is tapered towards the bearing surface 152 of the main body 134 so that one or more retaining projections 270 are formed.
Unwanted escape of a positioning element 256 and in particular a steel ball 260 from the through opening 262 can preferably be prevented by means of the retaining projections 270.
Escape of the positioning element 256 at an end of the through opening 262 opposite the bearing surface 152 is prevented by means of the closure element 266.
The spring element 264 is arranged between the closure element 266 and the positioning element 256. In this way, the positioning element 256 is preferably holdable in a positioning position in resilient yielding manner.
The positioning element 256 projects above the bearing surface 152 in this positioning position.
One or more positioning element seatings 258 are preferably formed such as to be at least partly complementary to the one or the plurality of positioning elements 256. In particular, the positioning element seatings 258 are formed such as to be complementary to the sections of the positioning elements that project above the bearing surface 152256 in the positioning position thereof.
Due to the resilient yielding mounting of the positioning elements 256, they can be moved into the main body 134, in particular, in order to enable the connecting elements 130 and the parts 102, 104 to be displaced relative to each other whilst the bearing surfaces 152 and/or the contact surfaces 106, 108 abut one another.
As soon as the connecting elements 130 are arranged in a desired position in which the positioning elements 256 are arranged opposite the positioning element seatings 258, the positioning elements 256 are moved automatically into the positioning element seatings 258 by means of the spring elements 264.
Simple positioning of the parts 102, 104 relative to each other can be effected in this way. In addition for example, the parts 102, 104 can thereby be latched to one another in order to facilitate the actuation of the retaining element 142 for the purposes of stably connecting the parts 102, 104 to one another.
In particular, provision may also be made for the connecting device 100 to comprise exclusively a positioning device 254 but no retaining element 142 for the purposes of bonding the parts 102, 104 to one another.
The fourteenth embodiment of a connecting device 100 that is illustrated in
Furthermore, the connecting device 100 can be used as a bonding aid in places in which pressure cannot be applied and in which pushing together or other processes of bringing two connecting elements 130 into engagement with one another is impossible.

Hereby, two connecting elements 130 that are insertable into a respective groove 110 in one of the parts of 102, 104 are provided.
Each of the connecting elements 130 comprises two screw seatings 230 for accommodating screws 162.
The hinge element 272 comprises two sections 276 that are pivotal relative to each other.
Each of the sections 276 comprises two elongate holes 278 through which the screws 162 are passed and which are provided for the purposes of fixing the respective section 276 to one of the connecting elements 130.
Recesses 280 can be provided in the connecting elements 130 for simple and/or aesthetically appropriate mounting of the hinge element 272 on the connecting elements 130.
In particular, protruding latches 282 of the sections 276 of the hinge element 272 are receivable in these recesses 280.
The elongate holes 278 are preferably arranged and/or formed in these latches 282.
The hinge element 272 can, for example, be a metallic part or be formed from metallic parts.

A sixteenth embodiment of a connecting device 100 that is illustrated in
To this end, the connecting device 100 comprises a movable and in particular linearly displaceable locking bar element 286.
The locking bar element 286 is a component of a connecting element 130 which is insertable into a groove 110 and which, in addition to the main body 134 and the locking bar element 286, comprises a drive shaft 288 and one or more magnet elements 190 for driving the drive shaft 288.
As can be perceived from
In particular, the toothed rack section 294 is in engagement with a pinion 298 of the rack-and-pinion device 296 which is arranged on the drive shaft 288.
The magnet elements 190 are also arranged on the drive shaft 288 so that the drive shaft 288 is rotatable together with the pinion 298 about a rotational axis 300 by means of the magnet elements 190, in particular, by external contactless actuation by means of a magnet device.
Due to the coupling of the pinion 298 to the toothed rack section 294 of the locking bar element 286, the locking bar element 286 is linearly displaceable, in particular, along a locking direction 302 by rotation of the drive shaft 288.
In particular, the locking direction 302 is substantially perpendicular to the bearing surface 152 and/or to the contact surface 106, 108 of at least one of the parts 102, 104.
The locking bar element 286 is accommodated or is accommodable in linearly displaceable manner in a locking bar element seating 304 of the main body 134 that is substantially complementary thereto.
The drive shaft 288 together with the magnet elements 190 and the pinion 298 is receivable or is accommodated in a shaft seating 306 of the main body 134 of the connecting element 130.
The locking bar element 286 is preferably movable along the locking direction 302 into the main body 134 to such an extent that the locking bar element 286 no longer projects above the bearing surface 152 and/or the contact surface 106, 108 of at least one part 102, 104.
In this position however, the locking bar element 286 may nevertheless project above the main body 134 at an end of the locking bar element seating 304 opposite the bearing surface 152 of the main body 134.
Consequently, this position of the locking bar element 286 can only be realized if the main body 134 is of sufficiently large dimensions as to accommodate the entire locking bar element 286 or if the part 102, in which the connecting element 130 comprising the locking bar element 286 is arranged, is provided with a recess 308 which adjoins the locking bar element seating 304 in the locking direction 302 (see
For the purposes of locking two parts 102, 104 together by means of the connecting device 100, the locking bar element 286 is moveable into the locking device position illustrated in
Then for example, the locking bar element 286 extends into a locking bar element seating 304 of a further connecting element 130 which is arranged in the further part 104. As an alternative or in addition thereto, provision may be made for the further part 104 to merely comprise a recess 308 for accommodating the locking bar element 286.
For the purposes of optimizing the transmission of torque from the magnet elements 190 to the drive shaft 288 and/or the pinion 298, there is provided, in particular, a drive shaft 288 having a non-rotationally symmetrical cross section such as a rectangular cross section for example. The magnet elements 190 and the pinion 298 then preferably comprise seatings corresponding thereto.
The drive shaft 288 can be a bar magnet for example.
Preferably, the magnet elements 190, the drive shaft 288, the pinion 298 and/or the toothed rack section 294 of the locking bar element 286 are dimensioned, formed and/or arranged in such a way that the locking bar element 286 is moveable from a retaining position into a release position, in particular, from a locking position into a release position by a rotation of the drive shaft 288 through 180°.
The locking bar element 286 can then be moved into the different desired positions in a particularly simple manner by placing a magnet on different side surfaces of the part 102.

Hereby for example, the magnet element 190 can be entirely integrated into the main body 134 of a connecting element 130, and in particular, be arranged within the main body 134 such as to be spaced from the bearing surface 152 of the main body 134.
Provision may also be made however for the magnet element 190 to extend within the main body 134 up to the bearing surface 152.
In the seventeenth embodiment of the connecting device 100 that is illustrated in
The parts 102, 104 are thus brought by means of the connecting device 100 into a position in which the spacings of the magnet elements 190 from each other are minimal.
Thereby, the parts 102, 104 do not necessarily have to be in contact with one another and in particular do not have to abut against each other. Rathermore, provision may be made for the parts 102, 104 to be arranged at a desired spacing A from each other.
Likewise, the connecting elements 130 of the connecting device 100 do not have to be brought into engagement with one another mechanically.
Consequently, it is not crucial for the connecting elements 130 to be arranged in grooves 110 which border on the contact surfaces 106, 108 of the parts 102, 104.
Rathermore for example, provision may be made for at least one connecting element 130 to be arranged in a groove 110 which borders a side surface 310, an end face 312 of the part 102 for example, that is oriented perpendicularly to the contact surface 106.
In particular, for the purpose of obtaining an aesthetically appealing arrangement of the parts 102, 104, provision may be made for the surfaces 108, 310, in which the grooves 110 and thus too the connecting elements 130 are arranged, to be provided with a respective cover element 314 after mounting the connecting elements 130.
For example, the cover element 314 can form an edge of the part 102, 104.
In principle and as already indicated in the preceding exemplary embodiments, a magnet element 190 is to be understood as being a magnetically interacting element.
The two magnet elements 190 thus do not necessarily both have to be magnetized. Rathermore for example, a magnetized magnet element 190 and a magnetizable element and in particular a steel element could be provided.

In place of a rotatable retaining element 142 for engaging the screw element 132, an actuating element 316 for operating the screw element 132 is provided instead.
In particular thereby, the actuating element 316 and the screw element 132 form an angle-driven screw device 318.
As can be perceived from
However provision may also be made for the further part 104 to comprise a screw seating 230, to be provided with a screw seating 230 or to be provided with a connecting element 130 which is arrangeable in a groove 110 in the part 104 and which is itself provided with a screw seating 230.
As an alternative to operation of a screw element 132 by means of the actuating element 316, provision may also be made for a nut to be operable by means of the actuating element 316 in order to accommodate a screw arranged on the further part 104.
In particular, connections to non-wooden materials can be established by means of connecting devices 100 of this type. Furthermore, these connecting devices 100 are suitable for use in or as shelf supports.

In particular, the latch hook 320 is moveable into engagement with a latch seating 322 which is arranged on the further connecting element 130.
In particular, the latch hook 320 is arranged on the one connecting element 130 in spring-like manner by means of a spring element 264.
In particular, the latch hook 320 can be moved along the direction of connection 170 from a rest position (see
The latch hook 320 and/or the latch seating 322 is preferably provided with at least one inclined surface 324.
In particular, the inclined surface 324 is inclined to the bearing surface 152 and/or to the contact surfaces 106, 108 of the parts 102, 104.
The inclined surfaces 324 thereby enable the latch hook 320 to be pushed into the main body 134 when the parts 102, 104 and thus too the connecting elements 130 are displaced in a transverse direction 326 running parallel to the bearing surface 152 and/or to the contact surfaces 106, 108.
Preferably however, this is only possible in a single transverse direction 326.
Hereby, the parts 102, 104 and the connecting elements 130 are preferably formed and/or arranged in such a way that this transverse direction 326 is opposed to the direction of the force of gravity g for the purposes of disengaging the latch hook 320.
When the part 102 is subjected to a load in a transverse direction 326 running parallel to the direction of the force of gravity g, the latch hook 320 preferably remains in the latch seating 322 so as to ensure a reliable and stable connection between the parts 102, 104.

In particular, a base construction 328 is a sub-construction of a floor covering or a wall panel.
As can be perceived from
For example, the connecting element 130 is formed in one-piece manner and comprises, in addition to a part 330 that is introducible into the groove 110, a projection 332 as well as an embracing section 334.
The projection 332 serves, in particular, for the arrangement and/or accommodation of the further part 104.
To this end in particular, the further part 104 is adapted to be pushed onto the projection 332 by means of a recess 336 such as a groove 110 for example.
The embracing section 334 of the connecting element 130 then embraces the part 102 on a side surface 310 thereof running transversely and in particular substantially perpendicularly to the contact surface 106.
The connecting element 130 thus surrounds a section of the part 102 in substantially a C-shape.
The embracing section 334 can, for example, extend parallel to the projection 332 so that the further part 104 is also enclosed in substantially a C-shape by the connecting element 130 in the installed state thereof.
As can be perceived from
A screw 162 is introducible into this through opening 154 particularly in order to fix the connecting element 130 including the part 102 or including both parts 102, 104 to the base construction 328 and in particular to screw it firmly thereto.
One or more parts 102, 104 preferably do not abut directly upon the base construction 328 due to the embracing section 334 of the connecting element 130.
Rather, a spacing A2 between the one or the plurality of parts 102, 104 is preferably formed by means of the embracing section 334.
Furthermore, the parts 102, 104 are also preferably held away from each other by a given spacing A1 by means of the connecting element 130.
The twentieth embodiment of the connecting device 100 that is illustrated in
For the mounting process hereby, provision may be made for a part 102 to be provided with one or more grooves 110 for example.
At least one groove 110 is then provided with a connecting element 130 by pushing the part 330 of the connecting element 130 that forms the main body 134 into the groove 110.
The embracing section 334 of the connecting element 130 thereby encloses the part 102 at the side surface 310 thereof.
In a next step, the part 102 together with the connecting element 130 is laid on the base construction 328.
In particular, the embracing section 334 of the connecting element 130 and the base construction 328 are brought into mutual abutment and screwed together by means of one or more screws 162.
A further part 104 is then fixed to the base construction 328 by pushing a pre-prepared recess 336 or groove 110 onto the projection 332 of the connecting element 130.
A further groove 110 into which a further connecting element 130 is in turn inserted is located or is provided on a side of the part 104 that is located opposite that side of the part 104 which serves to accommodate the projection 332 in order to fix it, together with the further part 104, to the base construction 328.
The screws 162 merely have to be removed in order to release the connection.
Preferably, the parts 102, 104 can then be displaced relative to each other in order to remove individual parts 102, 104.

Hereby, the spring elements 338 or latching elements 340 comprise spring noses 342 or latch noses 344 which are moveable into engagement with corresponding seatings 346.
For simplifying reference thereto hereinafter, the spring elements 338 and the latching elements 340 will be referred to as a whole as “latching elements 340”.
In consequence, the spring noses 342 and the latch noses 344 will be referred to as a whole as “latch noses 344”.
As can be perceived particularly from
Hereby, the latching elements 340 and the seatings 346 are arranged relative to each other in such a way that two latching elements 340 of different connecting elements 130 can be guided past each other and brought into engagement with the respectively associated seating 346.
As can be perceived from
Hereby, the latch noses 344 of the latching elements 340 are preferably arranged at different spacings from the bearing surface 152 of the respective connecting element 130.
Improved latching of the connecting elements 130 and thus improved connection of the parts 102, 104 can thereby be achieved.
As can be perceived from
In addition, provision may be made for each connecting element 130 itself to comprise two or more latching elements 340 which are arranged next to each other, wherein directly bordering latching elements 340 are preferably formed and/or arranged in such a manner that their latch noses 344 project away from each other in different directions.

In regard to this embodiment too, standardized reference will be made exclusively to latching elements 340 in the following. However, these latching elements 340 could also be simple spring elements 338.
In the case of the twenty-second embodiment of a connecting device 100 that is illustrated in
The rows 348 are arranged in parallel with each other.
Latch noses 344 of the latching elements 340 of a row 348 project away in the same direction.
Hereby, the latch noses 344 of each one of the rows 348 are arranged along a path in the form of an arc of a circle.
As can be perceived from
Hereby, the length of the latching elements 340, i.e. the spacing of the latch noses 344 of the latching elements 340 from the bearing surface 152 of the connecting element 130 is preferably selected in such a way that the latch noses 344 are insertable into a groove 110 of the type illustrated in
A simple latching connection between two parts 102, 104 can thus be established using just one connecting element 130 and two grooves 110.
Preferably the latch noses 344 are provided with (not illustrated) inclined surfaces so that the parts 102, 104 can be drawn together by the process of latching the latch noses 344.

In particular, a locking element 350 forms a retaining element 142.
Hereby, the locking element 350 can be in the form of a metallic bent part 352 for example.
As can be perceived from
The locking element 350 is preferably an element which is different from the main body 134 of the connecting element 130 and which, in particular, is fixable to the main body 134 in releasable manner.
For example, the locking element 350 comprises two engagement projections 146 which are formed and/or arranged such as to be movable relative to the main body 134 of the connecting element 130.
The further connecting element 130 comprises an actuating element 316 for actuating the locking element 350.
The actuating element 316 is in the form of an eccentric cam element for example.
The actuating element 316 is preferably accessible through a lateral access boring 128 in one of the parts 102, 104 particularly in order to rotate the actuating element 316 by means of a wrench and hence actuate the locking element 350.
As can be perceived from
Due to the fact that the locking element 350 and the actuating element 316 are arranged on mutually differing connecting elements 130, the lever arm ratios for actuating the locking element 350 can be optimized. The mechanical loading of the connecting device 100 during the process of locking it can thereby be reduced, whilst the stability and reliability of the connection is preferably retained or even improved.
In all other respects, the twenty-third embodiment of a connecting device 100 that is illustrated in

The clamping device 356 comprises one or more clamping projections 358 and one or more clamping elements 360.
A clamping projection 358 is arranged on one of the connecting elements 130 that are insertible into a groove 110 for example.
The clamping elements 360, four clamping elements 360 for example, are arranged on the further connecting element 130.
In particular, the clamping elements 360 are arranged on mutually opposite sides of a clamping seating 362.
The clamping projection 358 is substantially parallelepipedal.
The clamping elements 360 are preferably provided with a material having a high coefficient of friction at the ends thereof coming into contact with the clamping projection 358 or are formed from a material having a high coefficient of friction.
The clamping elements 360 are preferably formed in yielding, resilient and/or spring-like manner and/or are arranged on the main body 134 of the connecting element 130.
The clamping elements 360 preferably project into the clamping seating 362 at an angle to the bearing surface 152. In addition, the clamping elements 360 are preferably directed away from the bearing surface 152.
The clamping elements 360 can easily be moved to the side when pushing the clamping projection 358 into the clamping seating 362. The clamping projection 358 can thus be inserted into the clamping seating 362 without substantial resistance (see
The connection between the connecting elements 130 and thus the connection between two parts 102, 104 can thus be established in a simple manner.
The clamping projection 358 has to be withdrawn from the clamping seating 362 in order to release the connection.
Due to the shape and design of the clamping elements 360 here however, there is a greater resistance due, in particular, to the fact that the clamping elements 360 are moved onto the clamping projection 358 by the inclined arrangement and alignment and as a result the clamping force is reinforced still more.
It follows therefore that the clamping device 356 is a self-locking clamping device 356.
The clamping elements 360 can be formed by thrust collars for example.
In particular, the clamping projection 358 is a substantially parallelepipedal spigot.
In all other respects, the twenty-fourth embodiment of the connecting device 100 that is illustrated in
A twenty-fifth embodiment of a connecting device 100 that is illustrated in
Hereby, the latching elements 340 and/or the seatings 346 for the latching elements 340 are preferably resilient and/or yielding.
For example, provision may be made for the spherical latching elements 340 to be deformable in order to enable them to be inserted into the likewise spherical seatings 346.
In the twenty-fifth embodiment of the connecting device 100 that is illustrated in
Hereby, the spherical latching elements 340 are arranged at different spacings from the bearing surface 152. Optimal latching of the parts 102, 104 to one another can thereby be achieved.
In particular in the case where the seatings 346 for the latching elements 340 are always arranged at the same spacing from the bearing surface 152 of the connecting element 130 concerned, provision may be made for the spherical latching elements 340 to be introduced successively into the seatings 346 and latched thereto.
Preferably, latching of the connecting device 100 in different positions and in particular, at different spacings from the bearing surfaces 152 of the connecting elements 130 can thereby be realized.

In all other respects, the twenty-sixth embodiment of a connecting device 100 that is illustrated in
An alternative design of a groove 110 is illustrated in
This groove 110 is in the form of a partial groove 364.
The bottom surface of the groove 118 in this partial groove 364 actually extends in the form of an arc of a circle from the contact surface 106 of the part 102 into the part 102. However, the bottom surface of the groove 118 does not end again at the contact surface 106, but rather, within the part 102 or else at a side surface 310 of the part 102 (not illustrated in the drawings).
In the case of the embodiment of a groove 110 that is illustrated in
In particular, the stop surface 366 runs transversely to the contact surface 106.
The stop surface 366 preferably bounds the base section 112 and the undercut sections 114.
By suitably shortening the construction of the connecting elements 130, preferably all of the connecting elements 130 that are arrangeable in a groove 110 in accordance with
The partial groove 364 is producible by means of a (not illustrated) end-milling cutter for example.
A twenty-seventh embodiment of a connecting device 100 that is illustrated in
The connecting element 130 is preferably securable from unwanted displacement thereof within and/or along the groove 110 by means of the securing device 368.
In particular, the securing device 368 comprises a securing element 370 in the form of a securing projection which, in the installed state of the connecting element 130, comes into abutment, in particular, on a contact surface 106, 108 of a part 102, 104 and thereby secures the connecting element 130 against unwanted displacement within and/or along the groove 110.
In particular, the securing element 370 can be clamped between the parts 102, 104, between the contact surfaces 106, 108 of the parts 102, 104 for example, in order to secure the connecting element 130.
In all other respects, the twenty-seventh embodiment of a connecting device 100 that is illustrated in
A twenty-eighth embodiment of a connecting device 100 that is illustrated in
In particular hereby, the securing elements 370 are securing elements 370 that are in the form of and/or are arranged in resilient, yielding and/or spring-like manner.
The securing elements 370 are preferably moved automatically into a release position when inserting the connecting elements 130 into the grooves 110.
As soon as the connecting elements 130 are arranged in the given position in the groove 110 and in particular as soon as the bearing surface 152 of the connecting element 130 is oriented in parallel with and in particular is flush with the contact surface 106, 108 of the part 102, 104, the securing elements 370 preferably automatically reach a retaining position in which further displacement of the connecting element 130 within and/or along the groove 110 is effectively prevented.
The securing elements 370 are then supported, in particular, on the contact surface 106, 108 of at least one of the parts 102, 104.
In the case of the twenty-eighth embodiment of the connecting device 100 that is illustrated in
The guidance device 238 comprises a guidance element 240 which is arranged on a connecting element 130 and comprises one or more guidance projections 242.
In particular, the guidance element 240 is introducible into a guidance groove 244 of the further connecting element 130.
This guidance groove 244 comprises a guidance section 250 which is inter-engageable by the guidance element 240 by means of the guidance projections 242.
In particular, the guidance device 238 comprises a camming guide 376 which is formed by the guidance groove 244.
The camming guide 376 serves, in particular, for guiding the guidance element 240 along a given guide path.
This guide path has varying spacings along the guidance groove 244 from the contact surfaces 106, 108 of the parts 102, 104 and/or from the bearing surfaces 152 of the connecting elements 130.
In particular, the camming guide 376 provides a local minimum region 378 which is surrounded by two local or global maximum regions 380.
The maximum regions 380 are surrounded by run out regions 382 on the side thereof remote from the minimum region 378.
For the purposes of connecting the connecting elements 130 as well as the parts 102, 104 to one another, the connecting elements 130 are firstly arranged on the parts 102, 104.
In a next step, the parts 102, 104 together with the connecting elements 130 arranged thereon are displaced relative to one another so that the guidance element 240 of the one connecting element 130 enters into the guidance groove 244 of the further connecting element 130.
In particular thereby, the parts 102, 104 and the connecting elements 130 are displaced in parallel with the contact surfaces 106, 108 of the parts 102, 104.
Hereby, the guidance projection 242 firstly comes into engagement with a run out region 382 and is then fed across the maximum region 380 into the minimum region 378.
Due to the further maximum region 380 following this minimum region 378, this minimum region 378 is a stable position for the guidance projection 242 along the guide path formed by means of the camming guide 376.
The connecting elements 130 are thus connected to one another in stable manner when the guidance projection 242 is arranged in the minimum region 378 of the camming guide 376 (see in particular,
If so required, the guidance projection 242 together with the appertaining connecting element 130 and the appertaining part 102, 104 can also be pushed over the further maximum region 380 as well as out of the further run out region 382.
The connecting elements 130 are thus displaceable entirely past each other if necessary.
As can be perceived from
This indentation 384 is in the form of an arc of a circle for example.
Such an indentation 384 can be advantageous, in particular, when the connecting element 130 is intended to be arranged in a flat part 102, 104 and further guidance elements 240 are provided on the same part 102, 104 in addition to this connecting element 130.
For example, if two grooves 110 for accommodating connecting elements 130 are arranged on mutually opposite sides of a part 102, 104 and the grooves 110 project so far into the part 102, 104 that the grooves 110 intersect within the region of the bottom surfaces of the grooves 118, the indentation 384 can make it possible for two connecting elements 130 to be arranged in the part 102, 104 despite such an intersection.
In all other respects, the twenty-eighth embodiment of a connecting device 100 that is illustrated in
A twenty-ninth embodiment of a connecting device 100 that is illustrated in
In particular, this connecting element 130 can thus be inserted into a groove 110 which comprises only one undercut section 114 that extends away from the base section 112.
Such a groove 110 can be advantageous when using thin and less sturdy parts 102, 104 for example.
In principle, the reduction of the groove 110 and/or the connecting elements 130 to only one undercut section 114 and/or only one retaining projection 138 can be advantageous in all of the described and conceivable variants of grooves 110 and connecting elements 130.
In all other respects, the twenty-ninth embodiment of a connecting device 100 that is illustrated in
A thirtieth embodiment of a connecting device 100 that is illustrated in
The plug-in sections 386 can, for example, be provided with ribbing, lamella and/or other retaining elements in order to connect the connecting element 130 to the corresponding part 102, 104 in a stable manner.
In all other respects, the thirtieth embodiment of a connecting device 100 that is illustrated in
A thirty-first embodiment of a connecting device 100 that is illustrated in
Hereby, the connecting elements 130 are formed in such a way that they are receivable in partial grooves 364 (see
In the case of these partial grooves 364 in particular, provision is made for the bottom surfaces of the grooves 118 of the respective partial groove 364 to border on a contact surface 106, 108 at one side and on a side surface 310 of the respective part 102, 104 at the other side.
The connecting elements 130 arranged in the partial grooves 364 are fixable in the partial grooves 364 and thus in the parts 102, 104 by means of screws 162. The connecting elements 130 and thus too the parts 102, 104 are pivotal about the pivotal axis 284 by means of the hinge device 274.
As is apparent from a comparison of
In particular, the partial grooves 364 in the thirty-first embodiment of a connecting device 100 that is illustrated in
Hereby, the groove 110 is preferably formed in the parts 102, 104 in such a way that this groove 110 extends to substantially a half into the one part 102 and to substantially a half into the other part 104.
The partial grooves 364 are thus preferably half grooves, i.e. a half of a groove 110 in accordance with
In particular, a very stable and highly precise connection of two parts 102, 104 that are to be pivoted relative to each other can be established by means of a connecting device 100 in accordance with the thirty-first embodiment that is illustrated in
