Fastening device for releasably fastening a mechanism in the region of a floor of an aircraft or space craft and arrangement for a cargo loading system

摘要

A fastening device is disclosed for releasably fastening a mechanism in the region of a floor of an aircraft or spacecraft and includes a base component and a latch component. The latch component includes at least one holding portion including a latch-component-side holding face and is movably coupled to the base component between an unlocked and a locked position. When positioned in a predefined mounting position on the floor component and/or on the base component, the holding portion of the latch component engages a fastening portion, and the latch-component-side holding face faces the mechanism-side holding face. During passage of the latch component from locked position into unlocked position a gap between the latch-component-side holding face and the mechanism-side holding face continuously widens. The invention further relates to an arrangement for a cargo loading system.

主权项

1. A fastening device for releasably fastening a mechanism in the region of a floor, in particular a cargo hold floor, of an aircraft or spacecraft,
comprising a base component, which is provided so as to be rigidly coupled to a floor component which is formed for introducing a load into the floor; and comprising a latch component, which comprises at least one holding portion comprising a latch-component-side holding face and is coupled to the base component such that the latch component is movable between an unlocked position and a locked position with respect to the base component;wherein the latch component is formed such that, when the mechanism is positioned in part in a predefined mounting position on the floor component and/or on the base component, the holding portion engages around a fastening portion, which is formed on the mechanism and which comprises at least one mechanism-side holding face, in the region of the mechanism-side holding face during the passage of the latch component into the locked position, such that the latch-component-side holding face faces the mechanism-side holding face; and
the latch-component-side holding face is formed such that during passage of the latch component from the locked position into the unlocked position a gap between the latch-component-side holding face and the mechanism-side holding face continuously widens; wherein the base component is formed such that it can be brought into positive engagement with the fastening portion of the mechanism, when the mechanism is laid in part on the floor component and/or on the base component in the predefined mounting position, such that it is made possible for tensile loads to be transferred between the mechanism and the base component in a first direction, the first direction extending substantially perpendicular to a second direction, along which the fastening portion of the mechanism can be fixed by the cooperation of the latch-component-side holding face and the mechanism-side holding face; and wherein the base component comprises a projection which is formed and arranged such that the projection can be introduced into an associated opening of the mechanism, when the mechanism is laid on the floor component and/or on the base component, so as to bring about the positive engagement.
