It should be noted that the seal 24 with the arms 241 and 242 in the Fig. 1 for reasons of improved representation of underlying components is shown only shortened. The seal 24 and thus also the arms 241 and 242 can basically extend over the entire length of the door sill 2.

It is envisaged that the door sill 2 is equipped with a height adjustment device 25 for the seal 24.

The height adjustment device 25 essentially comprises a groove 251 with a bottom 2511, an insert profile 253 and at least one adjusting disk 252.

The groove 251 is provided in the profile arrangement, preferably in the first profile 21, and below the seal 24. The groove 251 extends in the longitudinal direction of the profile arrangement or of the first profile 21. The groove 251 preferably has a floor 2511 provided with steps. In particular, the floor 2511 is provided with at least one step, preferably a number of steps, extending in the longitudinal direction of the groove. The resulting "staircase" rises to a certain extent transversely to the longitudinal direction of the groove.

The insert profile 253 is essentially an elongated profile which is inserted into the groove 251. Preferably, the insert profile 253 extends over the entire length of the groove 251.Das insert profile 253 is slidably received in the groove 251 in the manner of a piston. The displacement direction is aligned perpendicular to the groove 251 and indicated by the arrow V. The insert profile 253 has on its bottom 2511 of the groove 251 side facing a surface 2531 with steps. The steps preferably extend parallel to the steps of the groove bottom 2511. On its side facing the seal 24, the insert profile 253 has, for example, a cross-sectionally T-shaped profile 2532 on which the seal 24 is mounted. Furthermore, the insert profile 253 is equipped with a number of holes 2533, which serve to carry out a tool connection 2522 of the adjusting disks 252.

The adjusting disk 252 or a number of adjusting disks 252 are mounted between the bottom 2511 of the groove 251 and the bottom 2531 of the insert profile 253. The adjusting disk 252 has on at least one side, preferably on both sides, a stair-step-shaped surface 2521. In particular, at least one step, preferably a number of steps, is also provided here, which are strung together in the manner of a spiral staircase. The adjusting disk 252 does not have to be configured as a complete circular disk. A section of a circular disk, in particular in the form of a semicircular disk, is also sufficient for the function envisaged here.

Furthermore, the adjusting disk 252 is equipped with a connection 2522, for example a pin with, for example, a hexagonal engagement, for a tool. Through the bore 2533 in the insert profile 253 of the connection 2522 can be achieved for the tool become. Also, the pin may be received in the bore 2533 in the manner of a pivot bearing.

The groove 251 and the insert profile 253 generally extend over the entire length of the door sill 2. Also, only one groove 251 and one insert profile 253 are provided per door clamp 2 in the rule. As a rule, at least two, preferably several, adjusting disks 252 are provided, which are arranged one behind the other in the longitudinal direction of the door sill 2.

Further details of the present invention will become apparent from a schematic representation of an adaptation of the seal 24 at different predetermined heights H with respect to the profile arrangement.

A first installation situation is in Fig. 8 shown, which is intended to represent a basic position of the seal 24, in particular the seal height Ho relative to the profile arrangement.

Another installation situation is in the Fig. 9 displayed. Here, a lowered by about 2mm from the basic position seal 24 is shown. To achieve a reduced height H _{-2 of} the seal 24 relative to the profile arrangement, the adjusting disk 252 has been rotated by 90 ° relative to the rotational position of the basic position. The axis of rotation is in this preferred embodiment, perpendicular to the groove bottom 2511 and is aligned in the direction of displacement V of the insert profile 253. It can also be provided that the adjusting disk 252 has a different axis of rotation. As a result of the rotation, another support of the step-shaped setting disk surface 2521 on the step surfaces 2511 of the groove bottom and the insert profile lower side 2531 with respect to FIG Basic position, which causes the insert profile 253 and thus the seal 24 is lowered relative to the basic position.

Another installation situation is in the Fig. 10 displayed. Here is shown a raised by about 1.5mm from the basic position seal. To achieve a greater height H _{1.5 of} the seal 24 relative to the profile arrangement, the adjusting disk 252 has been rotated by 180 ° relative to the rotational position of the basic position. The rotation results in a different edition of the adjusting disk 252 on the stair surfaces 2511 of the groove bottom and the insert profile bottom 2531 relative to the basic position, which causes the insert profile 253 and thus the seal 24 is raised relative to the basic position.

The tool connection 2522 or the pin can be provided on its visible upper side with a marking 2523, for example a notch, with which it is possible to deduce the rotational position of the adjusting disk 252.

As already mentioned, a number of setting disks 252 can be provided along the profile arrangement. In Fig. 2 Accordingly, a plurality of tool connections 2522, 2522 'or bores 2533, 2533' can be seen. This results in particular the advantage that a per length section individual height positioning of the seal 24 can be made. As a result, the gasket can be adjusted very individually to the conditions encountered, for example unevenness of the floor on which the door sill 2 is mounted.

It can also be seen that the proposed door threshold 2 or height adjustment device 25 a height adjustment of its seal 24th allows without, for example, parts must be replaced.
