Abstract

A passenger boarding bridge may include a tunnel having a first tunnel section and a second tunnel section. The first and second tunnel sections may be telescopic for adjusting a length of the tunnel along a sliding direction. The passenger boarding bridge may further include bearings configured to slidably support the first and second tunnel sections relative to one another. The bearings may include a bearing rail connected to the first tunnel section a bearing sledge connected to the second tunnel section. The bearing rail may comprise a planar first horizontal bearing surface, and the bearing sledge may comprise a planar second horizontal bearing surface that is configured to slide along the planar first horizontal bearing surface as the tunnel sections telescope.

First claim

What is claimed is:

1. A passenger boarding bridge comprising:
a tunnel having a first tunnel section and a second tunnel section, wherein the first and second tunnel sections are telescopic for adjusting a length of the tunnel along a sliding direction; and
bearings adapted to slidably support the first and second tunnel sections relative to one another, the bearings comprising,
a bearing rail connected to the first tunnel section, wherein the bearing rail comprises a planar first horizontal bearing surface, and
a bearing sledge connected to the second tunnel section, the bearing sledge comprising,
a bearing support attached to the second tunnel section,
a bearing shoe tiltably connected to the bearing support, and
a planar second horizontal bearing surface coupled to the bearing shoe and configured to slide along the planar first horizontal bearing surface as the first and second tunnel sections telescope.

2. The passenger boarding bridge of claim 1 wherein the bearing shoe is tiltably connected to the bearing support by a first hinge.

3. The passenger boarding bridge of claim 1 wherein the bearing shoe is tiltably connected to the bearing support by a first ball joint.

4. The passenger boarding bridge of claim 1 wherein the bearing shoe is tiltably connected to the bearing support along a first axis that is aligned horizontally and perpendicular to the sliding direction.

5. The passenger boarding bridge of claim 4 wherein the bearing shoe is tiltably connected to the bearing support along a second axis that is aligned horizontally and parallel to the sliding direction, and/or along a third vertical axis.

6. The passenger boarding bridge of claim 1 , wherein bearing surfaces of one of the bearings have a common planar contacting area of at least 20 cm 2 .

7. A passenger boarding bridge comprising:
a tunnel having a first tunnel section and a second tunnel section, wherein the first and second tunnel sections are telescopic for adjusting a length of the tunnel along a sliding direction; and
bearings adapted to slidably support the first and second tunnel sections relative to one another, the bearings comprising,
a bearing rail connected to the first tunnel section, the bearing rail comprising,
a planar first horizontal bearing surface, and
a planar first vertical guiding surface, and

a bearing sledge connected to the second tunnel section, the bearing sledge comprising,
a guiding support attached to the second tunnel section,
a guiding shoe tiltably connected to the guiding support,
a planar second horizontal bearing surface that is configured to slide along the planar first horizontal bearing surface as the first and second tunnel sections telescope,
a planar second vertical guiding surface coupled to the guiding shoe and in slidable contact with the planar first vertical guiding surface.

8. The passenger boarding bridge of claim 7 wherein the bearing sledge comprises:
a bearing support attached to the second tunnel section; and
a bearing shoe carrying the planar second horizontal bearing surface, wherein the bearing shoe is tiltably connected to the bearing support,
wherein the bearing shoe is tiltably connected to the bearing support by a first ball joint,
wherein the guiding shoe is connected to the bearing shoe by a second ball joint.

9. The passenger boarding bridge of claim 7 wherein the guiding shoe is tiltably connected to the guiding support along a first axis that is aligned horizontally and perpendicular to the sliding direction.

10. The passenger boarding bridge of claim 9 wherein the bearing sledge comprises:
a bearing support attached to the second tunnel section; and
a bearing shoe carrying the planar second horizontal bearing surface, wherein the bearing shoe is tiltably connected to the bearing support,
wherein the bearing shoe is tiltably connected to the guiding support along a second axis that is aligned horizontally and parallel to the sliding direction and/or along a third vertical axis.
