Abstract
A door sill protector includes a base rotatably mounted to a door sill via a hinge. The hinge allows the base to be rotated between a stowed position and a deployed position. A plurality of support feet are disposed on an underside of the base. Each of the support feet is pivotable for pivoting between an extended orientation and a retracted orientation. A linkage bar is mechanically coupled to the support feet such that the support feet collectively pivot in unison between the extended orientation and the retracted orientation.
Claims7
A door sill protector comprising:
- a base;
- a hinge configured for rotatably mounting the base to a door sill, wherein the hinge is configured to allow the base to be rotated between a stowed position and a deployed position, wherein the base extends outwardly above the door sill in the deployed position thereby protecting the door sill and providing a substantially flat surface that extends outside of a doorway for assisting with loading and unloading of cargo;
- a plurality of support feet disposed on an underside of the base, wherein each of the support feet is pivotable for pivoting between an extended orientation and a retracted orientation, wherein the support feet are pivoted to the retracted orientation when the base is in the stowed position such that the support feet are inside of the doorway thereby enabling closing of a door in the doorway;
- a linkage bar mechanically coupled to the support feet such that the support feet collectively pivot in unison between the extended orientation and the retracted orientation;
- and
- a wheel coupled to the linkage bar, wherein upon the base being in the stowed position, the wheel extends outside of the doorway via an arm such that the wheel contacts the door as the door is being closed thereby actuating the linkage bar to automatically pivot the support feet to the retracted orientation.
A door sill protector for an aircraft cargo door comprising:
- a platform configured for rotatably mounting onto an aircraft floor inside a cargo doorway;
- a hinge configured for operably coupling the platform to the aircraft floor, wherein the hinge is configured for rotating the platform between an upright stowed position inside the cargo doorway and a horizontal deployed position extending outside of the cargo doorway;
- a plurality of support feet disposed on an underside of the platform, wherein each of the support feet is pivotable for pivoting between an extended orientation and a retracted orientation, and upon the platform being in the horizontal deployed position, the support feet are pivoted to the extended orientation for supporting the platform by resting adjacent an outer edge of the cargo doorway along a bottom portion of the cargo doorway;
- a linkage bar mechanically coupled to the support feet such that the support feet collectively pivot in unison between the extended orientation and the retracted orientation;
- and
- a wheel coupled to the linkage bar, wherein upon the platform being in the stowed position, the wheel extends outside of the cargo doorway via an arm such that upon the aircraft cargo door being closed, the wheel contacts the door thereby actuating the linkage bar to automatically pivot the support feet to the retracted orientation.
