The fastening device 100 comprises a first gripping means 101, a second gripping means 102, a fastening means 103 and a fastening element 105. The first gripping means 101 and the second gripping means 102 can be pivoted relative to one another about a pivot axis. The fastening device 100 is fastened to a profile 106 with a groove 107 running in the longitudinal direction. The groove 107 has two undercuts into which the gripping elements of the gripping means 101 and 102 engage. Due to the undercuts, the groove 107 has approximately a T-shape and can therefore also be referred to as a T-groove.

The first gripping means 101 has a first recess through which a spreading means 201 is screwed. The spreading means 201 exerts a force on the second gripping means 102 so that the gripping elements are fastened in the undercuts of the groove 107 with a non-positive fit. The fastening device 100 can be fastened to the profile 106 at a variable height, since the two gripping means 101 and 102 can be displaced along the groove 107 and can be fixed at any position by means of the expansion means 201.

The second gripping means 102 has a receiving area for a fastening means 103 . A first leg 300 of the fastening means 103 protrudes into the receiving area, while a second leg 104 rests on a boundary of the receiving area. The fastening means is thus mounted in a form-fitting manner in the second gripping means 102 and can be removed from the receiving area without being fixed upwards, while lateral movement or downward movement is blocked.
The fastening element 105 is screwed into the second leg 104 . This serves - such as figure 2 can be seen - the attachment of a planking 200 to the attachment device 100. Alternatively, the attachment element 105 can also be designed as a rivet and be inserted in the second leg 104 in a form-fitting manner. The rivet can be made of plastic, for example. A plastic bearing 108 is arranged on the second leg 104, through which the fastening element 105 protrudes in the screwed-in or inserted state.

The planking 200 can be fastened to the fastening means 103, for example. The planking 200 can be formed, for example, as a laminated panel, glass, wood or sheet metal. The gripping means 101 and 102 are fixed in the groove 107 of the profile 106 using the expanding means 201 . Once this is done, the skin 200 can be easily attached to the profile 106 by inserting the first leg 300 of the fastener 103 into the receiving area of the second gripping means 102 .

As figure 3 As can be seen, the first leg 300 has a region 301 tapering conically towards one end, with which it is inserted in the receiving region of the second gripping means 102 . This tapered portion 301 is particularly advantageous when inserting the fastener 104 into the receiving portion, particularly since the skin 200 can be relatively heavy and cumbersome for a user. Preferably, the paneling is attached to multiple profiles using multiple fasteners. With this procedure, the conical areas 301 of the first legs 300 are particularly advantageous in order to introduce all the first legs 300 into the associated receiving areas.

A spring element 302 is arranged between the second gripping means 102 and the fastening means 103 . The spring element 302 offers an additional locking function. In addition, the spring element 302 reduces undesirable noises that can arise, for example, when there is play between the second gripping means 102 and the fastening means 103 and the second gripping means 102 repeatedly comes into contact with the fastening means 103 .
The second gripping means 102 also has a recess 400 through which a fixing means 500 can be screwed in order to fix the first leg 300 in the receiving area. In the state fixed by means of the fixing means 500, the first leg 300 can no longer be moved relative to the second gripping means 102. Without fixing means 500, on the other hand, removal of the first leg 300 upwards from the receiving area is possible. The fixing means 500 can be a screw, for example.

A washer 501 is inserted in a slot of the second gripping means 102 against which the fixing means 500 the first leg 300 presses. The slot is arranged directly adjacent to the receiving area. This has the advantage that when other fastening devices 100 are used at the same time to fasten the same add-on part, the respective first legs 300 are not also fixed. Thus, the fastening device 100 according to Figure 5A be used as a fixed bearing, while the other fasteners 100 can be used as a floating bearing. Such a floating bearing is, for example, in Figure 5B shown. The disc 501 can also be referred to as a washer, spacer or spacer ring, for example.

In figure 6 the receiving area 600 into which the first leg 300 can be inserted can be seen particularly well.

In figure 7 shows the first recess 700 in the first gripping means 101, through which the spreading means 201 is screwed in order to clamp the gripping elements in the undercuts of the groove 107.

In figure 8 the second recess 800 is shown in the second leg 104 of the fastening means 103, into which the fastening element 105 for fastening the planking 200 to the fastening device 100 can be screwed. For this purpose, the recess 800 can have an internal thread. Alternatively or additionally, a nut can also be inserted into the recess 800 .

In figure 9 the first gripping element 900 of the first gripping means 101 is shown, which engages in one of the undercuts of the groove 107. Also shown is the second gripping element 901 of the second gripping means 102, which fits into the other of the undercuts of the groove 107 grips and thus fastens the fastening device easily and securely to the profile 106.

In figure 10 a railing with several profiles 106 is shown, only some of which are provided with reference symbols for reasons of clarity. Two fastening devices 100 are fastened to some of the profiles 106 in each case. In each case one of the fastening devices 100 is fastened in an upper area of the respective profile 106 , while another of the fastening devices 100 is fastened in a lower area of the respective profile 106 .

The planking 200 is attached to the attachment devices 100 in the manner previously described.

Out figure 11 the assembly of the paneling 200 on the profiles 106 can be understood. The fastening means 103 are fastened to the skin with the fastening elements 105 . A plurality of second gripping means 102 each having a receiving area 600 are attached to a plurality of profiles 106 . For assembly, the first legs 300 of the fastening means 103 are now inserted into the receiving areas 600 . This step is in figure 11 indicated with a partially broken line. The conical areas 301 of the first legs 300 are helpful here.

In the inserted state, one of the first legs 300 can still be fixed in the receiving area with a fixing means 500, so that removal upwards out of the receiving area 600 is not easily possible. In addition, one or more fixed bearings can be produced quickly and easily in this way. It is also possible for this work step to be carried out for several of the first legs 300 .
