Abstract

A guiding assembly ( 300 ) for guiding a sliding door leaf ( 101 ) movable along a sliding door rail ( 110 ) is provided. The guiding assembly ( 300 ) comprises a bogie ( 130 ) having a first end ( 132 ) being provided with a first steering member ( 136 ) and a second steering member ( 138 ), and an opposite end ( 134 ) comprising at least one guiding element ( 122 ) being engaged with the sliding door rail ( 110 ), wherein the bogie ( 130 ) is connected to the sliding door leaf ( 101 ). The guiding assembly ( 300 ) further comprises a guiding rail ( 140 ) having first end section ( 140 a ) and a second end section ( 140 b ). The bogie ( 130 ) is configured to pivot relative the sliding door leaf ( 101 ) as the second steering member ( 138 ) travels along the guiding rail ( 140 ).

First claim

The invention claimed is:

1. A guiding assembly for guiding a sliding door leaf along a sliding door rail, the guiding assembly comprising:
a bogie being connected to the sliding door leaf, the bogie having a first end and an opposite second end, the first end comprising a first steering member configured to engage the sliding door rail and a second steering member, the opposite second end comprising at least one guiding element being engaged with the sliding door rail; and
a guiding rail having a first end section and a second end section, wherein the second steering member is configured to engage the guiding rail with the first steering member being disengaged from the sliding door rail, and
wherein the bogie is configured to pivot relative the sliding door leaf as the second steering member travels along the guiding rail.

2. The guiding assembly according to claim 1 , wherein the bogie is configured to pivot between a first position and a second position, wherein in the first position the first steering member is engaged with the sliding door rail, and wherein in the second position the second steering member is engaged with the guiding rail.

3. The guiding assembly according to claim 1 , wherein the first end section of the guiding rail is arranged at a first horizontal distance from the sliding door rail, and the second end section of the guiding rail is arranged at a second horizontal distance from the sliding door rail.

4. The guiding assembly according to claim 3 , wherein a horizontal distance between the first end of the bogie and the sliding door rail is increased when the second steering member is engaged with the first end section of the guiding rail and travels towards the second end section.

5. The guiding assembly according to claim 3 , wherein the first distance is smaller than the second distance.

6. The guiding assembly according to claim 1 , wherein the guiding rail is at least partly inclined.

7. The guiding assembly according to claim 1 , wherein the guiding rail comprises a bottom rail and a top rail.

8. The guiding assembly according to claim 1 , wherein the bogie is connected to the sliding door leaf by a door leaf attachment element, the door leaf attachment element being repositionable along the bogie.

9. The guiding assembly according to claim 1 , wherein the first steering member is a first steering wheel, and the second steering member is a second steering wheel.

10. The guiding assembly according to claim 1 , wherein the at least one guiding element is a guiding wheel.

11. The guiding assembly according to claim 1 , wherein the sliding door leaf is driven along the sliding door rail by a drive unit.

12. A method for providing a sliding door assembly for operating a sliding door leaf driven by a drive unit along a sliding door rail, the method comprising:
positioning the door leaf relative the sliding door rail;
positioning a guiding rail relative the sliding door rail; and
connecting a bogie to the drive unit and the door leaf, wherein the bogie has a first end and an opposite second end, the first end of the bogie comprising a first steering member configured to engage the sliding door rail and a second steering member, the opposite second end comprising at least one guiding element being engaged with the sliding door rail,
wherein the second steering member is configured to engage the guiding rail with the first steering member being disengaged from the sliding door rail, and wherein the bogie is configured to pivot relative the sliding door leaf as the second steering member travels along the guiding rail.
