## Background
CROSS REFERENCE
The present application claims the benefit of U.S. Provisional Application No. 61/158,093, entitled “U-Bean Support Mechanism for Luggage” filed on Mar. 6, 2009, the entire contents of which is incorporated herein in its entirety by this reference.


FIELD OF THE INVENTION
The present invention relates generally to a support mechanism for luggage, and more specifically to a support mechanism for luggage having U-shaped recesses within which one or more handles are positioned.
BACKGROUND OF THE INVENTION
Luggage is well known in the art and is used by travelers for transporting personal belongings between one location and another. Travelers typically prefer luggage having wheels and a pull-handle. Wheeled luggage is more easily pulled than carried over most terrain. Commonly when the luggage is wheeled, the pull-handle extends from the luggage framework to facilitate pulling the luggage and retracts into the luggage when the luggage is stowed or transported as cargo.
Telescoping luggage handles favored by travelers can become jammed due to over-packing of the luggage or external pressure on the luggage. For example, pressure on the telescoping luggage handles can be great enough to cause deflection within the luggage handles. The deflection caused by over-packing can be enough that the luggage handles cannot be extended (or in the alternative, stowed) or require a greater force than typically required to extend (or in the alternative, stow) the handles.
SUMMARY OF THE INVENTION
There is a need in the luggage industry for durable, light-weight luggage which protects personal belongings contained within the luggage. An object of the present invention is a luggage system having impact protection and structural support, as well as being durable and light-weight.
One aspect of the present invention is a reinforcement mechanism adapted for positioning within a piece of luggage having a retractable handle. The reinforcement mechanism comprises a generally rectangularly shaped support member having an upper end, a lower end, opposing lateral edges extending therebetween, and a front surface and a back surface. Preferably, the luggage reinforcement mechanism is comprised of at least one of a metal, a metal alloy, a polymer, a composite, a polymeric blend, a polymeric laminate, a fiberglass material, and a carbon fiber material, and a combination thereof.
One or more grooved passages are positioned on the front surface of the support member. The one or more grooved passages are adapted to receive at least a portion of a retractable handle assembly. In one embodiment, a pair of substantially parallel grooved passages is positioned on the front surface of the support member. Preferably, the grooved passages generally have one of a “U” or “C” cross-sectional shape. In another embodiment, the grooved passages extend substantially from the upper end and the lower end of the support member.
In a preferred embodiment, the reinforcement mechanism is interconnected to a lower bracket assembly. Even more preferred, the lower bracket assembly is positioned over a lower portion of at least a portion of the retractable handle assembly to provide structural support.
In one embodiment, one or more reinforcing ribs are positioned on the front surface of the support member. Preferably, the one or more reinforcing ribs are positioned between the pair of grooved passages. More preferably, the reinforcing ribs are aligned in a substantially parallel configuration. The reinforcing ribs can have a width and a depth, preferably the reinforcing rib width is from about 0.4 inches to about 1.0 inches and the rib depth is from about 0.5 inches to about 1.5 inches.
In a preferred embodiment, three reinforcing ribs are positioned on the front surface of the support member. Furthermore, the three reinforcing ribs are positioned in a substantially parallel configuration between the grooved passages.
In another embodiment, the reinforcement mechanism further comprises an attachment means for operably interconnecting the generally rectangularly shaped support member to an internal framework of the piece of luggage. Preferably, the attachment means comprises one or more of a screw, a blot, a pin and a rivet.
Another aspect of the present invention is a wheeled luggage system with a retractable handle and a storage compartment.

In one embodiment, the substantially rigid plate has at least one attachment mechanism positioned in the support member. The at least one attachment mechanism is adapted to attach the support member to the back wall of the storage compartment. In another embodiment, the luggage support member has opposing upper and lower mounting elements to interconnect the rigid plate to the back panel of the luggage piece.
In another embodiment, the retractable handle has a handle grip and at least one handle tube. In a preferred embodiment, the at least one handle tube reciprocates within an exterior tube. Preferably, the at least one handle tube can be selectively extended. In another preferred embodiment, the at least one handle tube is positioned at least partially within one of the grooved passages. Over a lower portion of at least one handle tube a lower bracket assembly is preferably positioned. The lower bracket assembly receives the lower portion of the retractable handle. The lower bracket assembly is positioned over the lower portion of the handle tube to provide structural support to the luggage system. Preferably, the luggage support member is positioned between the at least one handle tube and the back wall. The positioning of the luggage support member between the at least handle tube and back wall substantially provides impact protection to the at least one handle tube. In yet another embodiment, the retractable handle has a biased stop pin. The biased pin restrains the retractable handle from being extended when the biased pin is positioned within the lower bracket assembly. Preferably, the biased pin is located in the lower portion of the retractable handle.
The wheeled luggage system further has an upper housing assembly. The upper housing assembly has at least one passageway aligned with at least one grooved passage. The upper housing assembly passageway receives the at least one handle tube. The upper housing assembly is interconnected to the upper end of the support member. Furthermore, the lower bracket assembly is interconnected to the lower end of the support member. In one embodiment, the support member may comprise a substantially rigid plate. Preferably, the upper housing assembly nests with an upper end of the substantially rigid plate. More preferably, the upper end of the rigid plate fits within an interior portion of the upper housing. The upper housing slides over the at least one handle tube. The upper housing can be moved up and down the handle tube for interconnecting the upper housing with the support member.
Another aspect of the present invention is a retractable handle assembly adapted for use with a piece of luggage. The retractable handle assembly comprises a handle interconnected to a pair of handle tubes and a substantially rigid plate. The rigid plate has an upper end, a lower end and lateral edges extending therebetween, and a pair of grooved passages substantially aligned substantially parallel with the lateral edges at least one structural rib positioned parallel to the pair of grooved passages. In a preferred embodiment, the at least one structural rib is positioned proximate to the pair of grooved passages. Preferably, the grooved passages extend substantially between the upper end and the lower end of the rigid plate. The pair of grooved passages is adapted to receive the handle tubes. In a preferred embodiment the rigid plate has opposing upper and lower mounting elements to interconnect the plate to a back panel of the luggage piece.
The handle assembly further comprises an upper housing assembly and a lower bracket assembly. The upper housing assembly retains an upper portion of the handle tubes in a secure position. Furthermore, the upper housing assembly is interconnected to the upper end of the substantially rigid plate. The lower bracket assembly overlaps a lower portion of the handle tubes. Preferably, the lower bracket assembly is interconnected to the lower portion of the substantially rigid plate.
In a preferred embodiment, a lower end of at least one handle tube has a biased stop pin. The biased stop pin restrains the retractable handle from being extended beyond a predetermined position.
The handle assembly further comprises a pair of outer handle tube housings. The handle tubes reciprocate within a respective handle tube housing. Furthermore, the upper housing slidingly engages the outer tube handles to allow for minor adjustments during assembly. In a preferred embodiment, each of the outer tube handle tube housings fits into one of the pair of grooved passageways.
The support mechanism can be a load-bearing surface for the storage container. The support mechanism can substantially bear one or both of external and internal pressures applied to the storage container. The external and/or internal pressures supported by the support mechanism substantially insulate the pull handles from one or both of the external and internal pressures. Furthermore, the support mechanism can provide rigidity to the storage container, specifically about the back wall of the storage container. In one embodiment, the support mechanism provides rigidity to the back wall, while maintaining some degree of flexibility of the back wall. The support mechanism allows for a soft, flexible storage container with a substantially rigid back wall. Furthermore, the support mechanism can decrease the amount materials required to reinforce a suitcase, allow for faster and/or more easily assembly of a suitcase, and/or decrease manufacturing economics for manufacturing a suitcase.
