Cases, particularly wheeled cases such as luggage cases, can be difficult to maneuver. Often, luggage cases are pushed or pulled on two or four wheels via a handle extending from, and substantially aligned with, a side of the luggage case. Because the handle is offset to one side of the luggage case, pushing or lifting the luggage case via the handle is difficult, as the luggage case will naturally move toward its center of gravity.
What is needed is a luggage case with a handle oriented more centrally over the centroid or center of gravity of the case or the case's storage area.
In one embodiment, a case is provided, the case comprising: a body portion comprising a centroid; and a handle comprising a gripping portion, wherein at least a portion of the gripping portion extends above the centroid.
In another embodiment, a case is provided, the case comprising: a centroid; a handle comprising a gripping portion and at least one handle member; and a first frame member; wherein the first frame member is operatively connected to the handle; and wherein at least a portion of the gripping portion extends above the centroid.
In another embodiment, a case is provided, the case comprising: a body portion; a lid operatively connected to the body portion, a handle; and a first frame member; wherein the first frame member is operatively connected to the handle; wherein at least one of the lid and the first frame member comprises at least one closure mechanism; and wherein the at least one closure mechanism is configured to engage at least one of the first frame member and the lid.

To the extent that the term “includes” or “including” is used in the specification or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed (e.g., A or B) it is intended to mean “A or B or both.” When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995). Also, to the extent that the terms “in” or “into” are used in the specification or the claims, it is intended to additionally mean “on” or “onto.” To the extent that the term “selectively” is used in the specification or the claims, it is intended to refer to a condition of a component wherein a user of the apparatus may activate or deactivate the feature or function of the component as is necessary or desired in use of the apparatus. To the extent that the term “operatively connected” is used in the specification or the claims, it is intended to mean that the identified components are connected in a way to perform a designated function. To the extent that the term “substantially” is used in the specification or the claims, it is intended to mean that the identified components have the relation or qualities indicated with degree of error as would be acceptable in the subject industry. As used in the specification and the claims, the singular forms “a,” “an,” and “the” include the plural. Finally, where the term “about” is used in conjunction with a number, it is intended to include ±10% of the number. In other words, “about 10” may mean from 9 to 11.
As stated above, while the present application has been illustrated by the description of embodiments thereof, and while the embodiments have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art, having the benefit of the present application. Therefore, the application, in its broader aspects, is not limited to the specific details, illustrative examples shown, or any apparatus referred to. Departures may be made from such details, examples, and apparatuses without departing from the spirit or scope of the general inventive concept.
This application claims priority from U.S. Provisional Patent Application No. 61/813,952, filed on Apr. 19, 2013, which is incorporated by reference herein in its entirety.
