A wheeled luggage case (1) has a single telescoping handle arm assembly (10) and a cantilevered handle grip (11) which is rotatably attached to the top end (13) of the handle arm assembly, such that the plane of rotation of the grip is approximately parallel to the rolling direction of the luggage case. The cantilevered handle grip (11) rotates from a position approximately perpendicular to the telescoping handle arm assembly (10) to a position approximately 30° below the horizontal, and a resilient element is provided which urges the grip to rotate downwardly while in use. The invention provides an ergonomically comfortable wheeled luggage case by allowing the user to grasp the grip in a natural position and, simultaneously, increasing the amount of leverage available to prevent the luggage case from tipping over when it is rolled over uneven ground. Further, the resilient element distributes the weight of the luggage case evenly across the user's hand.

We claim: 1. A wheeled luggage apparatus, comprising: a) a wheeled luggage case; b) a handle assembly attached to the wheeled luggage case; c) a cantilevered handle grip rotatably attached to the handle assembly such that the plane of rotation of the grip is approximately parallel to the rolling direction of the wheeled luggage case and extending across an upright end of the wheeled luggage case, the cantilevered handle grip further having a hinge assembly which rotatably attaches the grip to the handle assembly, the hinge assembly having an upward stop flange and a downward stop flange which limit the rotation of the cantilevered hand grip around a hinge to approximately 30°. 2. The wheeled luggage apparatus of claim 1, wherein the hinge assembly further having a resilient element which supplies a force to the cantilevered handle grip and to the handle assembly, urging the grip to rotate downwardly around the hinge. 3. The wheeled luggage apparatus of claim 2 in which the resilient element is a spring. 4. The wheeled luggage apparatus of claim 1 in which the upward stop flange is positioned on an outside portion of the hinge such that the upward stop flange limits the upward rotation of the cantilevered handle grip to a position in which the grip is approximately perpendicular to the handle assembly. 5. A wheeled luggage apparatus, comprising: a) a wheeled luggage case; b) a telescoping handle arm assembly attached to the wheeled luggage case; and c) a cantilevered handle grip rotatably attached to the telescoping handle arm assembly such that the plane of rotation the grip is approximately parallel to the rolling direction of the wheeled luggage case and extending across an upright end of the wheeled luggage case, the cantilevered handle grip further having a hinge assembly which rotatably attaches the grip to the telescoping handle arm assembly, the hinge assembly having an upward stop flange and a downward stop flange which limit the rotation of the cantilevered handle grip around a hinge to approximately 30°. 6. The wheeled luggage apparatus of claim 5, wherein the hinge assembly further having a resilient element which supplies a force to the cantilevered handle grip and to the telescoping handle arm assembly, urging the grip to rotate downwardly around the hinge. 7. The wheeled luggage apparatus of claim 6 in which the resilient element is a spring. 8. The wheeled luggage apparatus of claim 5 in which the upward stop flange is positioned on an outside portion of the hinge such that the upward stop flange limits the upward rotation of the cantilevered handle grip to a position which is approximately perpendicular to the telescoping handle arm assembly. 9. The wheeled luggage apparatus of claim 5 in which a top surface of the grip is flush with an upright end of the wheeled luggage case, when the telescoping handle arm assembly is in a fully retracted position. 10. The wheeled luggage apparatus of claim 5 further having a grip cradle disposed within an upright end of the case, the cantilevered handle grip being adapted to be releasably locked within the cradle when the telescoping handle arm assembly is in a fully retracted position, allowing the grip to be used to carry the wheeled luggage apparatus. 11. The wheeled luggage apparatus of claim 5 further having a release button disposed within the grip, allowing a user to depress the button to unlock the grip from a grip locking assembly. 12. The wheeled luggage apparatus of claim 11 in which the button is adjacent to a back end of the cantilevered handle grip. 13. The wheeled luggage apparatus of claim 11 in which the button is flush with a top surface of the cantilevered handle grip. 14. A wheeled luggage apparatus, comprising: a) a wheeled luggage case; b) a telescoping handle arm assembly attached to the wheeled luggage case; c) a hinge assembly which rotatably attaches a cantilevered handle grip to a top end of the telescoping handle arm assembly such that the plane of rotation of the grip is approximately parallel to the rolling direction of the wheeled luggage case and the grip extends across an upright end of the wheeled luggage case when the grip is rotated upward, d) a resilient element disposed within the hinge assembly which supplies a force to the cantilevered handle grip and to the telescoping handle arm assembly, urging the grip to rotate downwardly around a hinge; e) an upward stop flange which is disposed on an outside portion of the hinge such that the flange abuts against the top end of the telescoping handle arm assembly and limits the upward rotation of the cantilevered handle grip around the hinge to a position in which the grip is oriented approximately perpendicular to the handle arm assembly; and f) a downward stop flange which is disposed on an inside portion of the hinge such that the flange abuts against the top end of the telescoping handle arm assembly and limits the downward rotation of the cantilevered handle grip to a position which is approximately 30 degree below the grip's perpendicular orientation to the handle arm assembly. 15. The resilient element of claim 14 in which the element is a spring. 16. The cantilevered handle grip of claim 14 in which a top surface of the grip is flush with an upright end of the wheeled luggage case, when the telescoping handle arm assembly is in a fully retracted position. 17. The wheeled luggage case of claim 14 further having a grip cradle disposed within an upright end of the case, the cantilevered handle grip being adapted to be releasably locked within the cradle when the telescoping handle arm assembly is in a fully retracted position, allowing the grip to be used to carry the wheeled luggage apparatus. 18. The cantilevered handle grip of claim 14 further having a release button disposed within the grip, allowing a user to depress the button to unlock the grip from a grip locking assembly. 19. The release button of claim 18 in which the button is adjacent to a back end of the cantilevered handle grip. 20. The release button of claim 18 in which the button is flush with a top surface of the cantilevered handle grip.
