As an embodiment, the figures show a holding device according to the invention 10 ,

The holding device 10 of the 1 has a device holder 11 for receiving a mobile device 12 and a fastening device 13 for attachment to a vehicle, not shown here.

In the 1 . 2 and 3 is the holding device 10 without the fastening device 13 shown. The 4 . 5 and 6 on the other hand show the holding device 10 , which is mounted with the fastening device 13 on the vehicle.

The fastening device 13 is in the 4 to 6 by way of example on a tubular vehicle part here 23 attached to the vehicle. It can affect the vehicle part 23 For example, to a rod, a frame part, a guard or mounting bracket, in particular a handlebar or the like act. For attachment to the vehicle, the fastening device 13 here a clamp holder 14 on.

This clamp holder 14 Here is essentially two jaws 15 formed, with each other by means of screws 16 are connectable. Here is a first screw 16 as a joint, while a second screw 16 for squeezing the jaws 15 is arranged. The second screw 16 If necessary, it can also be replaced by a bolt or split pin. Alternatively, let the jaws 15 also connect in other ways, for example by means of snap-in connections, clamp connections, bayonet-type closures or the like. The jaws 15 have here corresponding to a tubular counterpart on the vehicle semi-cylindrical recesses, which are designed to enclose the tubular counterpart.

As an alternative to the clamping jaws shown here, they can of course also be designed for other cross sections of a respective counterpart on the vehicle. For example, they may be provided with elliptical, rectangular, square or even generally polygonal cross sections of the recesses or sections of combinations thereof. But there are, for example, by spring action clamping or held together jaws 15 conceivable. The fastening device 13 or directly the device holder 11 can also be connected by direct bolting or gluing to the vehicle.

The connection between the holding device 10 and the device holder 11 is here by a coupling device 17 produced. The coupling device 17 becomes from corresponding coupling elements 18 . 19 educated. This is a ball head element 18 on the fastening device 13 and a corresponding spherical shell element 19 on the device receptacle 11 , The ball head element 18 is here indicated only with its lower section indicated. The ball head element 18 has an external thread 20 on. Meanwhile, the spherical shell element 19 with one to the external thread 20 corresponding union nut 21 equipped with an internal thread 22.

The ball head element 18 and the spherical shell element 19 are connected to each other by means of the union nut 21. By means of the ball head element 18 and the spherical shell member 19 is the device receptacle 11 Therefore, relative to the fastening device 13 pivotable and optionally also rotatable. The attachment of the two elements 18 and 19 one another takes place here by means of the union nut 21 and the external thread 20 ,

The device holder 11 is to record the mobile device 12 educated. For this purpose, it has two holding elements in the present case 24 on, the two transverse sides 25 are assigned to the mobile device 12. The holding elements 24 serve to the transverse sides 25 of the mobile device 12 So here are the shorter sides to hold.

The device holder 11 has a longitudinal ridge 27 as a stiffening element on which the retaining elements 24 by means of several springs or flat form springs 26 are resiliently mounted. Alternatively to the flat form springs described here by way of example 26 In principle, however, it is also possible to use other suitable types of spring, such as, for example, spiral springs or stretch marks.

The flat form springs 26 have spring forces especially when deflected in the direction of their Longitudinal extension up. Perpendicular to it, namely in the plane of the flat form springs 26 , as well as above and below this level are also available, but different spring effects.

The spring action in the direction of the longitudinal extent serves for resilient mounting of the mobile device 12. For fastening the mobile device 12 are the flat form springs 26 with the holding elements attached thereto 24 deflected by tensile forces in the longitudinal direction of the flat form springs 26, so as to insert and when releasing a grasping of the mobile device 12 to enable. The mobile device 12 can then only in this deflected state between the two holding elements 24 be used. In particular, only in the deflected state is there sufficient free space for inserting the mobile device 12 available. The holding elements 24 are then returned to the transverse sides of the mobile device by the flat form springs 26 due to their spring action when released 12 used. This is how the mobile device becomes 12 detected by the holding elements 24 and thus by the device receptacle 11 held.

To attach the mobile device 12 in the device holder 11 So here is a controlled deformation of the device recording 11 , These are the corresponding deformable designed areas, so the flat shape springs 26 , intended. The flat form springs return 26 typically does not completely return to baseline when the mobile device 12 is used. This is because the mobile device 12 typically has slightly larger dimensions than the spacing of the retention elements 24 at rest. Instead, the flat form springs remain 26 with inserted mobile device 12 slightly under tension, so that a secure support of the mobile device 12 by means of the holding elements 24 he follows.

Depending on the design of the device holder 11 and depending on the dimensions of each mobile device 12 can be different mobile devices 12 into a specific device receptacle 11 deploy. On the one hand, this depends on the shape and design of the retaining elements 24 as well as the respective mobile device 12 , On the other hand, this is mainly the spring elements 26 , in particular their elastic strain ranges dependent.

At the same time, the flat form springs 26 also provide for a resilient mounting of the mobile device 12. For this purpose, the spring action is responsible perpendicular to the longitudinal extension of the flat form springs 26. This may be due to a slight remaining voltage with built-in mobile device 12 get supported. Two directly or parallel offset arranged opposite or acting springs 26 thus ensure a spring effect in vibrations in a spatial direction.

Typically, the springs 26 at least substantially diagonally or laterally offset to the device receptacle 11 acting arranged. Thus, two pairs of springs aligned angularly relative to one another can already provide for a vibration suspension in the entire plane. Typically, the two diagonals are affected. This is made possible by the springs 26 can also be deflected perpendicular to its longitudinal axis, namely laterally.

Because the flat form springs 26 , but alternatively also other types of springs, even in the direction perpendicular to a spring effect with appropriate deflection show, this is also a resilient suspension in to the device holder 11 vertical direction. In this respect, a three-dimensional resilient mounting is shown here.

If necessary, it is desirable to achieve stiffening in individual spatial directions, in particular for selective vibration damping. For example, in the vertical direction, only a lower oscillation amplitude than in the plane of the mobile device 12 may be allowed, in particular an independent detachment of the mobile device 12 from the device receptacle 11 to prevent.

To adjust the stiffness can be stiffening elements 27 provide as shown in the drawings. It may vary in the stiffening elements 27 Accordingly, therefore, in particular to leaf springs, stiffening strips or the like act. Due to their rigidity, these stiffening elements 27 reduce the freedom of movement, typically perpendicular to their longitudinal extent.

Both the flat form springs 26 as well as the stiffening elements 27 are each with first end with a base plate 28 the device holder 11 connected. On the other hand, they are with their respective other end with the holding elements 24 connected.

Here are the flat form springs 26 typically cohesively with the base plate 28 as well as the holding elements 24 connected. This allows movement and spring action in all spatial directions. Optionally, a frictional or positive connection of the components may be provided.

Meanwhile, the stiffening elements 27 at least on one side cohesively and / or non-positively and / or positively with the holding elements 24 or the base plate 28 may be connected. This is particularly dependent on the type of production. Thus, a stiffening effect can be achieved only perpendicular to this degree of freedom. The stiffening element 27 can then go in the direction be stored freely movable longitudinally, for example in a recording 29 of the holding element 24 sliding. In order to perpendicular movement and / or torsion but the stiffening element 27 must be deflected, so that thus a stiffening is achieved.

Such a design linearly movable stiffening elements 27 is for example in the 3 shown. These are the holding elements 24 in a partial section in a plane parallel to the device receiving level 11 shown, so that the internal structure of the base plate 28 with the spring elements 26 you can see. The pictures 29 become visible through it. Optionally, the device recording 11 Also suitable to be dismantled into several parts, leaving the base plate 28 with the spring elements 26 and the stiffening elements 27 of the holding elements 24 is so separable.

The stiffening elements 27 also point here to the recording 29 associated end portions each cross pieces 32 as a pawl on. These limit the freedom of movement of the holding elements 24 relative to the stiffening element 27 to a maximum extent. These are inside the retaining elements 24 the recordings 29 designed to correspond, on the one hand to allow a certain range of motion and on the other hand, a further moving out of the stiffening elements 27 with the cross pieces 32 from the recording 29 to prevent. This defines a maximum range of motion. In addition, by the leverage of the cross pieces 32 allows the initiation of torsional moments with lower support forces.

To operate a mobile device 12 in the holding device 10 To simplify, further features may be provided. For example, a cable holder 30 be provided for attachment of a cable, not shown here. Cables, such as power cords, headphone cords, or the like, typically come with corresponding ports on the front ends of the mobile device 12 connected. For this purpose, the device holder 11 suitable recesses 31 in the area of the holding elements 24 have, so that even in the assembled state of the mobile device 12 a corresponding connection is possible.

During manufacture, the device holder 11 be formed integrally. This can be done for example by additive manufacturing processes, such as injection molding or 3D printing. Here, the advantage of easy manufacturability of the spring elements used, ie flat-form springs revealed 26 on the one hand and stiffening elements 27 on the other. Ideally, these can be easily produced in a single operation.

The advantage of an additive manufacturing lies above all in a possible one-piece construction of the entire device receptacle 11 or at least combinations of individual components thereof. For example, flat form springs can be used 26 with holding elements 24 and / or stiffening elements 27 and possibly also the base plate 28 in each case in one another in different combinations.
