Abstract

An aircraft comprising an opening for accessing a compartment and a ladder. The aircraft comprises at least one support. The ladder comprises at least one fastener element connected to a support by a removable connection comprising a pivot axis.

First claim

The invention claimed is:

1. An aircraft comprising:
an opening configured to access a compartment;
at least two supports;
a ladder comprising at least two vertical stiles connected by rungs therebetween, wherein a first end of each of the stiles respectively has a fastener element removably connected to each of the two supports by a removable connection comprising a pivot axis, wherein the ladder is rigid and non-hinged with respect to itself, the ladder comprises two sides, the ladder has a major length along the two sides that spans from a lower end of the ladder to an upper end of the ladder which comprises the first ends of the stiles;
a storage slide configured to receive the ladder when the ladder is in a storage position, wherein said storage slide is not directly attached to the two supports, wherein the ladder is configured to move between the storage position and an access position, wherein the fastener elements of the ladder are directly attached to the two supports when in the access position, wherein the ladder is detached and separated from the two supports when being moved from the access position to the storage position, and wherein the ladder is received within the storage slide when in the storage position;
wherein said ladder comprises at least one spacer which is separate from the fastener elements, and wherein at least one of said two supports comprises a bearing surface against which said at least one spacer bears when the ladder is in the access position;
wherein each of said two sides of said ladder comprises a respective through-hole located in each of the fastener elements, wherein each of said two supports respectively comprises a clevis with two through-openings, wherein said removable connection comprises a pin, and wherein each of said fastener elements of said two sides is respectively provided in the clevis of each of said two supports when the ladder is in the access position; and
wherein said storage slide comprises two side rails respectively having a C-shaped cross section arranged opposite to one another in parallel, wherein said storage slide comprises at least one end cross-member connecting said two side rails of said storage slide, and wherein each of said two side rails of said storage slide are configured to receive a respective one of the two sides of said ladder.

2. The aircraft according to claim 1 , wherein said pin comprises a ball-lock system actuatable by a button.

3. The aircraft according to claim 1 , wherein each of said two sides of the ladder comprises an extension inclined relative to a remainder of said two sides of said ladder, and a first of said fastener elements is positioned at a free end of one of said extensions.

4. The aircraft according to claim 1 , wherein said storage slide further comprises a strap, which comprises a first end connected to a first of said two side rails of said storage slide and a second end equipped with a detachable connection that cooperates with a second of said two side rails of said storage slide.
