Abstract

A track container for receiving the track of a lift device actuator is disclosed. The track container is elastically deformable from a rest position to a deflected position to accommodate the track. The track container includes a guide member in the form of a leaf spring configured to guide the track into the track container.

First claim

1 . A track container for receiving the track of a lift device actuator, wherein the track container is elastically deformable from a rest position to a deflected position to accommodate said track, wherein the track container comprises a guide member in the form of a leaf spring configured to guide said track into the track container.

2 . A track container according to claim 1 , comprising a peripheral wall with a corrugated or concertina configuration.

3 . A track container according to claim 1 , comprising a biasing member that is configured to elastically bias the track container into the rest position.

4 . A track container according to claim 1 , wherein when the track container is elastically deformable in a direction transverse the central axis of the track container.

5 . A track container according to claim 1 , configured such that if the track is retracted into the track container when ice is present in the track container, the track container elastically deforms to accommodate the ice and the track.

6 . A track container according to claim 5 , wherein the track follows a curved path when retracted into the track container and wherein the track container has a curved shape when in the rest position that corresponds to said curved path of the track.

7 . A track container according to claim 1 , wherein the track container is configured such that the track exerts a force on the track container each time the track is retracted into the track container to urge the track container into the deflected position.

8 . A track container according to claim 7 , wherein the track container is substantially straight in the lengthwise direction when the track container is in the rest position.

9 . A track container according to claim 7 , wherein the track container is configured such that when the track container is mounted to an aircraft structure the track container extends substantially horizontally in the lengthwise direction of the track container.

10 . A track container according to claim 1 , wherein the guide member is configured such that when said track is retracted into the track container said track exerts a force on the guide member that causes the guide member to urge the track container into the deflected position.

11 . A track container according to claim 1 , wherein the guide member comprises a resilient sheath and, preferably, the resilient sheath comprises an elastomeric material.

12 . A track container according to claim 1 , manufactured from a fibre reinforced plastic.

13 . A track container according to claim 1 , manufactured from a low ductility metal and, preferably, comprising an aluminium casting.

14 . A track container according to claim 1 , wherein the track container is configured to receive a curved slat track.

15 . An aircraft structure comprising a lift device, a track and a track container configured to receive the track, wherein the track container is elastically deformable from a rest position to a deflected position to accommodate the track, wherein the track container comprises a guide member in the form of a leaf spring configured to guide said track into the track container.

16 . An aircraft structure comprising a lift device, a track and a track container configured to receive the track, wherein the track container is elastically deformable from a rest position to a deflected position to accommodate the track, wherein the track container comprises a guide member in the form of a leaf spring configured to guide said track into the track container, wherein the track container extends substantially horizontally in the lengthwise direction of the track container when the track container is in the rest position and wherein the track container is configured such that the track exerts a force on the track container each time the track is retracted into the track container to urge the track container into the deflected position.
