[0040] FIG. 11 shows a perspective illustration of the rear side of the mounting and of the fastening plate of the holding piece that points to the rear side of the mounting;

[0041] FIG. 12 shows a section through the mounting and of an end portion of the holding piece having the fastening plate, in order to highlight the position of inserted permanent magnets;

[0042] FIG. 13 shows the arrangement according to FIG. 12 in an assembled state.

[0043] FIG. 1 shows a receptacle part which has a housing 2 having a planar lower side 3 and a sculpted, curved upper side 4. The housing 2 is provided with a front end side 5 and a rearward end side 6. As is highlighted in FIG. 2, the rearward end side is closed while the front end side 5 has a slot-shaped entry opening 7, the width of the latter being significantly greater than the height thereof, wherein the width-to-height ratio of the entry opening is greater than 2:1, in particular greater than 2.5:1, and preferably greater than 3:1.

[0044] FIGS. 1 and 2 show that the sculpted, curved upper side 4 continuously decreases in height from the front end side 5 to the rear end side 6.

[0045] The housing 2 enables an electrical connector cable 8, which in the exemplary embodiment illustrated is configured as a flat cable having three conductors 9, to be routed through at the rearward end side 6. The three conductors can carry the positive pole, the negative pole (ground) and a switching signal ignition on/off.

[0046] The sculpted, curved upper side 4 of the housing 2, from the entry opening 7 laterally across the entire length of the housing, bears directly on the lower side 3 and there is raised toward the center, on account of which the space for the rectangular slot-shaped entry opening 7 is made available in the region of the front end side 5. A receptacle duct 10 which extends from the entry opening 7 toward the rear and which by virtue of the upper side 4 that drops toward the rear is in a corresponding manner continuously reduced in height toward the rear and terminates at an end wall 11 is configured in the interior of the housing. Three contacts 12 which are configured as spring contacts and which in each case are connected to one of the three conductors 9 protrude through the end wall 11. Protrusions 13 which protrude further into the receptacle duct 10 than the spring contacts 12 are located between the contacts 12. It is achieved on account thereof that the contact points 12 cannot be shorted, for example by way of a coin that is dropped or pushed into the receptacle duct 10.

[0047] Preferably a plurality of magnets 15 which are preferably permanent magnets and of which only one is illustrated in FIG. 2 are located in a base 14 of the receptacle duct. The permanent magnets in an identical orientation form a magnetic north pole N and a magnetic south pole S which lie sequentially so as to be transverse to the longitudinal direction of the receptacle duct 10 (push-fitting direction), such that the south pole S is disposed so as to point toward the receptacle duct 10, and the north pole N is disposed so as to point away from the receptacle duct 10.

[0048] The slot-shaped entry opening 7 by way of a pivotably mounted flap 16 under the action of a spring is pivoted about a rotary bearing 17 to a closed position which is illustrated in FIG. 2. The free end of the flap herein in relation to the base is pivoted by somewhat more than 90 such that the flap 16 and the base 14 enclose an obtuse angle on the internal side of the receptacle duct 10. A narrow object that acts on the flat 16 thus slides down in the direction of the rotary bearing 17 and impedes the opening of the flap 16. In order for the receptacle duct 10 to be opened, the flap 16 has to be pivoted inwardly from the closed position illustrated in FIG. 2 toward the inside of the receptacle duct 10 until the flap comes to lie in a matching clearance 18 of the base 14, thus vacating the receptacle duct 10.

[0049] FIG. 3 shows a holding piece 20 which is configured to be received in the receptacle part 1 and which has an appendage 21, the shape of the latter being adapted to the shape of the receptacle duct 10. Accordingly, the appendage 21 in terms of the height thereof tapers continuously such that said appendage is guided in the receptacle duct 10 in a stable manner and by way of tight tolerances.

[0050] The appendage 21 has two strips 22 that are inserted into the surface of the former on the upper side. Two corresponding strip 22 are furthermore located on the lower side (not illustrated in FIG. 3). The strips 22 are composed of a textile material, in particular a flocked textile material, and as a scratch protection in the push-fitting movement protrude somewhat beyond the neighboring surface.

[0051] In the push-fitting of the appendage 21 into the receptacle duct 10 a secured position results from latching cams 23 which are provided laterally on the appendage and which can latch in a sprung manner into corresponding latching clearances 24 (FIG. 2) of the receptacle duct 10. To this end, the latching cams 23 are usually provided with a sawtooth-like run-on ramp which is adjoined by a latching ramp having a significantly steeper incline. On account thereof, significantly less force is required for pulling the appendage 21 into the latching position than for extracting the appendage 21 from the latching position. The appendage 21 at the free front end thereof has a clearance 34 in which the protrusion 13 that is located between the contact points 12 in the end wall 11 of the receptacle duct 10 is received, such that the appendage 21 by way of end-side contact faces (not illustrated) can contact the contact points 12.

[0052] FIGS. 3 and 4 highlight that the appendage 7 is part of a first portion of the holding piece 20. The first portion 24 by way of a first horizontal rotary joint 25 is connected to a second portion 26 of the holding piece 20. Said second portion 26 forms a rigid connection piece and by way of a second horizontal rotary joint 27 is connected to a third portion 28 of the holding piece 20. The three portions 24, 26, 28 of the holding piece 20 thus form an apparatus arm which by way of a more or less intense Z-shaped mutual articulation of the portions enables the adjustment at different heights and at variable spacing from the receptacle part 1 when the holding piece 20 is push-fitted into the receptacle part 1.

[0053] A fastening plate 29 of circular configuration, by way of a vertical rotary joint 30 that is perpendicular to the axes of the horizontal rotary joints 25, 27, is connected on the third portion 28.

[0054] On account thereof, the fastening plate 29 is pivotable about a vertical axis. As can be seen in particular in FIG. 5, the fastening plate 29 is provided with a twist/lock closure. By placing corresponding latching cams in an initial position, said latching cams by way of a rotating movement can run on latching ramps that are disposed in a helical manner and by way of the effect of a sprung plate can be urged to a latching position behind the latching ramp. The contact pressure of the spring can be released with the aid of a lever 32 such that a reverse rotation out of the twist/lock closure 31 is possible.

[0055] The electrical potentials are routed through the holding piece 20 by way of the rotary joints 25, 27, and 30, said electrical potentials reaching three contact faces 33 on the fastening plate 29 that are disposed in an asymmetrical manner, as will be explained in more detail hereunder.

[0056] FIGS. 6 and 7a and 7b once again highlight the fastening of the holding piece 20 in the receptacle part 1 by push-fitting the appendage 21 into the receptacle duct 10. The flap 16 which has been pushed downward by the appendage 7b can be seen here in FIG. 7.

[0057] It can be seen in FIG. 7 that the magnets 15 that are located in the base 14 of the receptacle duct 10 have a magnetic pole (presently the south pole S) that points toward the receptacle duct 10, and a magnetic pole (presently the north pole N) that points away from the receptacle duct 10. The appendage 21 is provided with corresponding magnets 35 which have an alignment of a north pole N and of a south pole S that likewise runs transversely to the longitudinal axis of the appendage 21.

[0058] As is highlighted in FIG. 7b, the magnets 15, 35 interact when the appendage 21 is being push-fitted into the receptacle duct 10. The magnetic poles N, S herein are positioned such that in the completely push-fitted state of the appendage 21 the magnetic pole N of the magnet 35 in the appendage 21 is moved close to the magnetic pole S of the magnet 15 in the base 14 of the receptacle duct 10. On account thereof, the appendage 10 is magnetically pulled into the receptacle duct 10.

[0059] By contrast, if the appendage 21 were to be push-fitted into the receptacle duct 10 in an incorrect position rotated by 180, like poles N and S are noticeably moved closer together, on account of which an increasing counterforce acting against the push-fitting of the appendage 21 into the receptacle duct 10 is created. Therefore, using a normal effort in terms of force, it is not possible for the appendage 21 in the (incorrect) position rotated by 180 to be pushed into the receptacle duct 10 so far that a latching position is reached. By contrast, in the correct alignment of the appendage 21, the appendage 21 by the magnets 15, 35 is pulled into the receptacle duct 10 up to the secured position which results from the interaction between the latching cams 23 and the latching clearances 24 (FIG. 2). The maximum magnetic force is reached when the unlike poles of the magnets 15, 35 are completely aligned with one another, that is to say are in mutual alignment by way of the central axes of said magnets 15, 35. As is highlighted in FIG. 7b, in particular by way of the illustrated enlargement, this position does not have to be precisely reached in practice.

[0060] The rotary joints 25, 27, 30 of the holding piece 20 are configured as self-inhibiting rotary joints in that the latter are provided with plates that can be tensioned in relation to one another. The electrical potentials can be transmitted through the rotary joints by way of the alternating configuration of metallic plates and isolation plates.

[0061] A mounting 40 is attachable in a latching manner to the fastening plate 29 of the holding piece 20, said mounting being illustrated in FIGS. 8 to 11. The mounting 40 has a circular rear wall 41 that corresponds to the shape of the fastening plate 29, two lateral holding arms 42 extending from said rear wall 41 in lateral direction, and one holding arm 43 configured as a base bracket extending downward from said rear wall 41. The holding arms 42, 43 are provided with clamping jaws 44, 45 which are specified for bearing on a telecommunications apparatus 46 that is configured substantially as a flat cuboid (FIG. 10).

[0062] FIG. 8 shows the holding arms 42, 43 in the maximum deployed position thereof; FIG. 9 shows the holding arms 42, 43 in the maximum retracted position thereof.

[0063] The holding arms 42, 43, in a manner known per se, from the maximum deployed position in FIG. 8 are adjustable in only one direction. According to FIG. 10, the telecommunications apparatus 46 is inserted into the mounting 40 having the holding arms 42, 43 deployed to the maximum. Thereafter, the holding arm 43 that is configured as a base bracket is displaced upward, that is to say is pulled in toward the rear wall 41, until a suitable position for the telecommunications apparatus 46 has been reached. Thereafter, the lateral holding arms 42 are retracted, wherein the movement of said holding arms 42 is interlinked such that only an adjustment of the lateral holding arms 42 that is symmetrical to the central axis is possible. It is achieved on account thereof that the telecommunications apparatus is always held so as to be symmetrical to the vertical central axis of the fastening plate 29.

[0064] The rear wall 41 is provided with a charging induction coil (not illustrated in the drawing) which is actuated by way of the supply voltage when the ignition is switched on. The mounting 40 is consequently specified for the inductive charging of a telecommunications apparatus 46 that is provided therefor. On account of the displacement of the holding arm 43 that is configured as a base bracket, the telecommunications apparatus is displaced in front of the rear wall 41 upward until the electronics located in the rear wall 41 determine a maximum correlation between the charging induction coil located in the rear wall 41 and the coil located in the telecommunications apparatus 46. At this point in time the mounting 40 emits an indicator signal indicating to the user that the optimum position of the telecommunications apparatus 46 in the mounting has now been reached. The indicator signal in the exemplary embodiment illustrated is a visual indicator signal which is generated by an LED in the rear wall. The holding arm 43 that is configured as a base bracket is configured as a light duct and is thus immediately identifiably illuminated when the position of the telecommunications apparatus 46 that is suitable for inductive charging has been reached. Thereafter, the adjustment of the holding arm 43 that is configured as a base bracket should be concluded. The telecommunications apparatus by way of the clamping jaws 44 of the lateral holding arms 42 is subsequently laterally clamped and on account thereof securely held in the mounting 40. Releasing the holding arms 42, 43 is possible by activating an unlocking button 47 which separates a toothed locking feature from the holding arms 42, 43 such that the latter can be returned to the deployed position thereof according to FIG. 8.

[0065] The rear side of the rear wall 41, which is adapted to the shape of the fastening plate 29, can be seen in FIG. 11. Five spring contacts 48 which are disposed in a symmetrical manner are located on the rear side. The central spring contact herein is provided for the ground potential and contacts a centrical contact face 33 of the fastening plate 29. The two spring contacts that are located beside the central spring contact can be connected to the positive pole, for example, while the outer spring contacts can be connected to the ignition on/off signal, for example. The mounting 40 in terms of polarity is thus always supplied with the correct electrical signals or potentials, respectively, in both possible connecting positions which differ by 180.

[0066] The mounting is thus also capable of being locked to the fastening plate with the holding arm 43 that forms the base bracket facing upward, should this be required by the installation situation.

[0067] By virtue of the holding piece 20, the telecommunications apparatus 46 that is held in the mounting 40 can be held at different heights, spacings, and lateral inclinations, such that the position that is optimal to a viewer is adjustable.

[0068] Indicated in the illustration of FIG. 11 are permanent magnets 50 in the rear wall 41 of the mounting 40, as well as permanent magnets 51 in the fastening plate 29 of the holding piece 20. The mutual position of the holder 40 and of the holding piece 20 illustrated corresponds to the locked, that is to say assembled position in which the permanent magnets 50 and 51 are in each case opposite one another. The permanent magnets 50, 51 in the exemplary embodiment illustrated are configured as rectangular plates which are magnetized such that the north pole and the south pole, respectively, are present on the large faces of said plates. The magnets herein are located on the same radius about the rotation axis of the rotating movement by way of which the mounting 40 is securable on the holding piece 20. To this end, four L-shaped appendages 52 are molded on the rear side 41 of the mounting 40, said appendages 52 in an initial position being introducible into corresponding ramp guides 53 of the fastening plate 29, and by way of the ramp being movable to a latching position by way of a rotating movement about the rotation axis that is perpendicular to the rear wall 41.

[0069] FIG. 12 in a sectional illustration highlights that in the latching position illustrated the permanent magnets 50 and 51 in each case by way of unlike poles N, S point toward one another. The permanent magnets 50, 51 in the initial position are mutually spaced apart in the circumferential direction, exerting a considerable attracting force by way of which the holder 40 is pulled to the correct position relative to the fastening plate 29 of the holding piece 20.

[0070] FIG. 13 shows the final assembled state of the latching position.
