Claims18
A loading apparatus comprising:
- a set of stairs comprising at least two risers and a plurality of treads disposed between the risers;
- a platform, wherein the set of stairs are attached to the platform and the platform includes a biased latch;
- and
- a first handle having a first end, a second end, and a body portion therebetween, wherein the first end of the first handle is pivotally attached to the set of stairs and the biased latch engages the body portion of the first handle to secure the first handle in a deployed position while the set of stairs are also secured in a deployed position,
- wherein the biased latch further comprises an outwardly-facing angled face and an inwardly-facing flat face,
- wherein the biased latch is constructed and dimensioned such that during a locking step when the body portion of the first handle contacts the outwardly-facing angled face of the biased latch, the biased latch deflects from a resting position to a biased position.

A loading apparatus comprising:
- a set of stairs;
- a platform attached to the set of stairs, wherein the platform includes a biased latch;
- and
- a handle having a first end, a second end, and a body portion therebetween, wherein the first end of the handle is pivotally attached to the set of stairs and the handle is constructed and dimensioned such that in a storage configuration the handle is positioned substantially parallel to the set of stairs, and in an operational configuration the handle is positioned such that the biased latch engages the body portion of the handle to secure the handle in a deployed position while the set of stairs are also secured in a deployed position,
- wherein the biased latch further comprises an outwardly-facing angled face and an inwardly-facing flat face,
- wherein the biased latch is constructed and dimensioned such that during a locking step when the body portion of the first handle contacts the outwardly-facing angled face of the biased latch, the biased latch deflects from a resting position to a biased position.

A loading apparatus comprising:
- a set of stairs comprising at least two risers and a plurality of treads disposed between the risers;
- a platform having a front edge and a rear edge, wherein the set of stairs are attached to the platform at a point between the front edge and the rear edge of the platform and the platform includes a locking mechanism attached to the front edge of the platform;
- and
- a handle having a first end, a second end, and a body portion therebetween,
- wherein the first end of the handle is pivotally attached to the set of stairs, and
- wherein the locking mechanism engages the body portion of the handle to secure the handle in a deployed position while the set of stairs are also secured in a deployed position, and disengages the body portion of the handle while the set of stairs are in a stowed position,
- wherein the locking mechanism further comprises an outwardly-facing angled face and an inwardly-facing flat face,
- wherein the locking mechanism is constructed and dimensioned such that during a locking step when the body portion of the first handle contacts the outwardly-facing angled face of the locking mechanism, the locking mechanism deflects from a resting position to a deflected position.
