Abstract

A support trolley for supporting a door of an aircraft to permit working on the door comprises a frame with an upper support portion having at least two pairs of support bolts for engagement with locking bolts of the door to be supported so that the door is supported at each lateral side by a pair of support bolts. For engagement with the locking bolts the support bolts comprise recesses at their free ends.

First claim

1 . A support trolley for supporting a door of an aircraft to permit working on the door, wherein a frame with an upper support portion comprising at least two pairs of support bolts with a receiving recess at its free end for engagement with locking bolts of the door to be supported so that the door is supported at each lateral side by a pair of support bolts.

2 . The support trolley according to claim 1 , wherein the support bolts are movable between a release position in which the locking bolts can be brought in engagement with the support bolts, and a support position in which the support bolts are fixed to the upper support portion.

3 . The support trolley according to claim 2 , wherein in its support position the support bolt is held by a releasable clamping mechanism which comprises a clamp with a pivotable element and a clamping bolt.

4 . The support trolley according to claim 1 , wherein the receiving recess is arranged eccentrically with respect to the longitudinal axis of the support bolt.

5 . The support trolley according to claim 1 , wherein the support bolts are provided on support beams height-adjustably mounted on the upper support portion.

6 . The support trolley according to claim 1 , wherein the distance between the support bolts of both pairs of support bolts is adjustable.

7 . The support trolley according to claim 1 , wherein the upper support portion comprises a sub-frame on which the support bolts are mounted and which in its horizontal position is located in a plane parallel to a support plane formed by rollers of the trolley, and that the sub-frame is pivotable out of its horizontal position about an axis which extends in parallel to the axes of the support bolts.

8 . The support trolley according to claim 7 , wherein the axis is located offset from a middle of the sub-frame by between 15% and 20% of the length of the subframe.

9 . The support trolley according to claim 7 , wherein the sub-frame can be locked in its horizontal position and in at least one inclined position.

10 . The support trolley according to claim 1 , wherein the frame is provided with rollers and wherein the upper support portion comprises a sub-frame on which the support bolts are mounted, wherein the sub-frame is rotatable with respect to the frame about an axis of rotation which extends perpendicular with respect to the axes of the support bolts and in parallel to a support plane formed by the rollers.

11 . The support trolley according to claim 10 , wherein the sub-frame can be locked in a horizontal position in which the axes of the support bolts extend in a plane parallel to the support plane formed by the rollers, and in several inclined positions.

12 . The support trolley according to claim 10 , wherein an elongated support strut is releasably attached to the sub-frame and extends in parallel to the axis of rotation which support strut comprises positioning elements for engagement with the door.

13 . The support trolley according to claim 12 , wherein in the horizontal position of the sub-frame the elongated support strut extends in a plane which extends perpendicular with respect to the support plane.

14 . The support trolley according to claim 12 , wherein the elongated support strut comprises at least one transverse arm extending at both sides of the support strut and carrying at least two positioning elements.

15 . The support trolley according to claim 10 , wherein the sub-frame is mounted between supporting struts located at the ends of the frame so that the subframe can be rotated by 360°.

16 . The support trolley according to claim 15 , wherein at the at least one supporting strut at one end of the frame a crank mechanism with a crank handle is provided which crank mechanism is coupled with a shaft secured to the subframe coaxially with respect to the axis of rotation.
