(18) FIGS. 1 to 5 will be discussed initially hereinbelow. FIG. 1 shows a schematic illustration of a hinge band 1 for a partition element 2 in a first position. FIG. 2 shows the hinge band 2 according to FIG. 1 in a second position. FIG. 3 shows the hinge band according to FIG. 1 in the first position, having a clamping unit removed. By contrast, FIG. 4 shows the hinge band 1 according to FIG. 2 in the second position, having the clamping unit removed. FIG. 5 shows a detailed view of the region Z according to FIG. 3. The same reference signs at all times indicate the same components.

(19) The first position is, for example, a closing position of the petition element 2. The partition element 2 is, for example, a door, particularly a glass door or a glass swing door. In the case of the exemplary embodiment illustrated in FIGS. 1 to 5 the partition element 2 is configured as a pane of a glass door. The second position of the partition element 2 is an open position of the hinge band 1. The second position in relation to the first position is disposed in such a manner that the partition element 2 in the open position (cf. FIG. 2) is disposed so as to be pivoted by 90 in relation to the first position (cf. FIG. 1).

(20) The hinge band 1 has a first band part 3 and a second band part 4. The first band part 3 is provided with the receptacle installation 6. The receptacle installation 6 has a first clamping unit 7 and a second clamping unit 8 for disposing the partition element 2 in a clamping manner between the first clamping unit 7 and the second clamping unit 8. The second band part 4 is configured so as to be plate-shaped and by way of fastening means 5 can be disposed on a floor of a room, for example. For example, screws are suitable as fastening means 5.

(21) The first band part 3 is connected to the second band part 4 for hinge action about a hinge axle pin 9 in such a manner that the first band part 3 is rotatable relative to the second band part 4 about a rotation axis 10. The hinge axle pin 9 is, for example, a metal pin, particularly a cylindrical metal pin. A cylinder axis of the metal pin in this instance corresponds to the rotation axis 10. The invention is not limited to a metal pin. Rather, any pin which is suitable for the invention can be used as the hinge axle pin.

(22) The hinge band 1 furthermore has a lifting/lowering installation 11 which is disposed on the first band part 3 as well as on the second band part 4. On account of the lifting/lowering installation 11 the first band part 3 in a movement of the first band part 3 relative to the second band part 4 about the rotation axis 10 is moved along the rotation axis 10. For example, this movement has been performed in a movement of the first band part 3 from the closed position (cf. FIGS. 1 and 3) relative to the second band part 4 to the open position (cf. FIGS. 2 and 4). It is particularly provided that in a movement of the first band part 3 from the first position to the second position, the first band part 3 rotates about the rotation axis 10, on the one hand, and moves away from the second band part 4 in the direction of the rotation axis 10, on the other hand.

(23) The lifting/lowering installation 11 has a first hinge axle unit 12 and a second hinge axle unit 13. The first hinge axle unit 12 is disposed on the first band part 3. It is particularly provided that guiding protrusions 15 which engage in guiding receptacles 16 which are disposed on the first clamping unit 7 of the receptacle installation 6 (cf. FIG. 6) are configured on an external face 14 of the first hinge axle unit 12. In this way, the first hinge axle unit 12 is securely held on the first band part 3. One end of the first hinge axle unit 12 bears on a support face 17 of the receptacle installation 6. The support face 17 can be configured, for example, on the first clamping unit 7 and/or on the second clamping unit 8. In a movement of the first band part 3 relative to the second band part 4, the first hinge axle unit 12 raises the first band part 3 in relation to the second band part 4. The movement of the first band part 3 relative to the second band part 4 along the rotation axis 10 occurs. This will be explained in yet more detail further below.

(24) The hinge axle pin 9 is fixedly disposed on the second band part 4. The second hinge axle unit 13 is disposed on the hinge axle pin 9 by means of a clamping installation 18. The second hinge axle unit 12 is thus disposed on the second band part 4. This will be discussed in yet more detail further below.
