Abstract

Embodiments of the present disclosure provide an entry assist system for an aircraft doorway. The system includes a securement member configured to be secured into at least one aperture of the doorway, a handle portion pivotally attached to the securement member, and a releasable locking feature for locking the handle portion. A mounting device is used for securing the stationary member to an existing aperture in the doorway and for removing the entry assist system when no longer needed. The securement member forms a stationary portion along an inner edge of the doorway. The handle portion includes a hub configured for rotating about an axle that is coupled to an interface of the securement member. The hub and interface interconnect to form the releasable locking feature for locking the handle in a collapsed position adjacent the securement member or in an extended position protruding outside the doorway.

First claim

What is claimed is:

1. A removable handle for an aircraft doorway, comprising:
a stationary member for mounting along an inner edge of the aircraft doorway;
a mounting device configured for removably securing the stationary member to an existing aperture in the aircraft doorway;
a pivoting member having a hub configured for rotating about an axle, wherein the axle is coupled to an interface of the stationary member such that the pivoting member pivots about the axle between a collapsed position adjacent the stationary member and an extended position protruding outside the aircraft doorway, wherein the interface comprises a first receptacle configured to house a first spring-loaded spud, and wherein the hub comprises a slot configured to receive the first spring-loaded spud, such that the first spring-loaded spud extends into the slot for locking the pivoting member in place when the first receptacle is aligned with the slot; and
an actuator having a leg configured for inserting into the slot of the hub opposite the interface, wherein the leg is configured to push the first spring-loaded spud into the first receptacle upon actuation of the actuator thereby enabling unlocking the pivoting member for pivoting.

2. The removable handle of claim 1 , wherein the stationary member is shaped with a curvature that matches the inner edge of the aircraft doorway.

3. The removable handle of claim 1 , wherein the stationary member comprises a flanged collar for receiving the mounting device.

4. The removable handle of claim 1 , further comprising a second receptacle configured to house a second spring-loaded spud, the second receptacle being oriented in the interface for aligning the pivoting member in the extended position such that the second spring-loaded spud extends into the slot for locking the pivoting member in place when the second receptacle is aligned with the slot.

5. A removable handle for an aircraft doorway, comprising:
a stationary member for mounting along an inner edge of the aircraft doorway;
a mounting device configured for removably securing the stationary member to an existing aperture in the aircraft doorway;
a pivoting member having a hub configured for rotating about an axle, wherein the axle is coupled to an interface of the stationary member such that the pivoting member pivots about the axle between a collapsed position adjacent the stationary member and an extended position protruding outside the aircraft doorway; and
wherein the mounting device comprises a first end having a pair of laterally extending plates configured for inserting into an inner portion of the existing aperture and a second end having an actuating head configured for driving a ram pin to deploy the laterally extending plates.

6. A removable handle for an aircraft doorway, comprising:
a stationary member for mounting along an inner edge of the aircraft doorway;
a mounting device configured for removably securing the stationary member to an existing aperture in the aircraft doorway;
a pivoting member having a hub configured for rotating about an axle, wherein the axle is coupled to an interface of the stationary member such that the pivoting member pivots about the axle between a collapsed position adjacent the stationary member and an extended position protruding outside the aircraft doorway; and
a kick-out foot hingeably attached to the mounting device for pressing against an outer portion of the existing aperture upon actuation by the actuating head to prevent lateral movement of the mounting device.

7. An entry handle for an aircraft doorway, comprising:
a stationary member having an axle housed in an interface, the stationary member being removably secured to the aircraft doorway via a mounting device coupled to an aperture of the aircraft doorway;
the mounting device having a first end with a pair of laterally extending plates configured for inserting into an inner portion of the aperture, and a second end having an actuating head configured for driving a ram pin to deploy the laterally extending plates; and
a pivoting member having a hub configured to receive the axle such that the pivoting member may pivot about the axle from a collapsed position to an extended position.

8. The entry handle of claim 7 , wherein the interface comprises a first pair of receptacles aligned on opposing sides of the axle, and a second pair of receptacles aligned on opposing sides of the axle such that the first pair of receptacles is oriented relative to the second pair of receptacles by a first angle, and the receptacles are configured to house spring-loaded spuds.

9. The entry handle of claim 8 , wherein the hub comprises a first pair of slots aligned on opposing sides of the axle, and a second pair of slots aligned on opposing sides of the axle such that the first pair of slots is oriented relative to the second pair of slots by a second angle, the second angle being different from the first angle, such that the slots are configured to receive the spring-loaded spuds for locking the pivoting member.

10. The entry handle of claim 9 , wherein the first pair of receptacles aligns with the first pair of slots for receiving the spring-loaded spuds to lock the pivoting member when oriented in the collapsed position, and the second pair of receptacles aligns with the second pair of slots for receiving the spring-loaded spuds to lock the pivoting member when oriented in the extended position.
