CROSS-REFERENCE TO RELATED APPLICATION AND PRIORITY

The present application is a continuation-in-part of U.S. patent application Ser. No. 12/982,493, filed Dec. 30, 2010, which claims priority to U.S. Patent Provisional Application Ser. No. 61/299,727, filed Jan. 29, 2010 and entitled “Hard-Sided Expandable Suitcase,” the entirety of both are incorporated by reference herein. This application is also related to co-pending U.S. patent application Ser. No. 13/444,924, filed Apr. 12, 2012.

FIELD OF THE INVENTION

The present application relates to luggage, and more particularly to hard-sided suitcases and telescopic luggage handles.

BACKGROUND

Currently, consumers have a variety of different options when it comes to luggage for their personal belongings and/or other articles. For example, consumers can use suitcases, briefcases, computer cases, beauty cases, business cases, travel bags, and a host of other types of cases. People often spend considerable resources to ensure that they have suitcases which are both durable and stylish. However, in addition to desiring a suitcase which is both durable and styling, people also seek suitcases which provide a significant amount of storage space and compartments, without being cumbersome and unwieldy. Many available suitcases come in a variety of sizes which feature a plurality of pockets and storage compartments.

Soft-sided suitcases have been provided in expandable versions, however once a soft-sided suitcase has been expanded to fit in extra clothing and other belongings, it may not be possible to compress them back to their original size because of the stresses that this puts on the fabric that forms the suitcase. This means that the suitcase may have to be carried in the expanded state, which may mean that the suitcase no longer meets an airline size requirements, or that the carrying handles become offset with respect to the center of weight of the suitcase, making the case unwieldy to carry. However, hard-sided suitcases have generally not been successfully expandable. Currently available hard-sided suitcases have thus often had to be provided in larger sizes to ensure larger storage capacities, which may result in a suitcase which may be inconveniently large for many consumers. Additionally, larger hard-sided suitcases may weigh an unacceptably high amount, even while empty, which can use up too much of an airline weight restriction amount for the luggage.

It is desirable to provide expandable hard-sided suitcases in novel configurations.

Additionally, conventional luggage handles include, for example, those disclosed by U.S. Design Pat. No. D536,875 (entitled “Luggage Handle”); U.S. Pub. No. 2011/0168507 (entitled “Steerable Carriage Apparatus”); U.S. Pat. No. 5,865,281 (entitled “Retractable Luggage Handle Mounting Hardware”); U.S. Pat. No. 5,397,151 (entitled “Retractable Luggage Handle Mounting Assembly”); U.S. Pat. No. 6,857,512 (entitled “Selectively Rotatable Handle Assembly for Towable Luggage”); U.S. Pat. No. 7,226,073 (entitled “Luggage Cart Having a Telescoping Handle With the Addition of a Foldable Supportive Wheel Assembly”); and U.S. Pub. No. 2010/0095480 (entitled “Universal Bracket and Luggage Handle System”). However, conventional luggage handles may have various drawbacks, such as being poorly designed, providing inadequate space within a luggage compartment, having rough interior or exterior surfaces, being cumbersome and unwieldy, having several components and insufficient strength and durability, and/or having other deficiencies.

 DETAILED DESCRIPTION OF THE INVENTION

The exemplary embodiments of the present disclosure are described with respect to a hard-sided suitcase for carrying and/or storing different types of articles. It should be understood by one of ordinary skill in the art that the exemplary embodiments of the present disclosure may be applied to other types of hard-sided suitcases. Referring to the drawings, an embodiment of a hard-sided suitcase 10 for storing articles is illustrated. Notably, the suitcase may comprise a variety of different types of luggage. For example, the suitcase may be a traditional suitcase, a briefcase, a laptop bag/case, a computer bag/case, a business case, a travel bag, a beauty case, or a variety of other types of luggage. Of course, the aforementioned types of suitcases are merely for illustrative purposes and are not intended to limit the suitcase to the listed varieties.

The hard-sided suitcase 10 may include front, back, side, and top and bottom portions. The suitcase 10 may include two hard-sided shells 20, which may be utilized to form one or more storage compartments for the hard-sided suitcase 10. Outer portions of the hard-sided shells may form at least a portion of the front, back, sides, top and bottom portions. The inner portions of the hard-sided shells may be lined with various types of fabrics or other similar features and may include one or more pockets, which may be opened and closed through zipper mechanisms or other mechanisms for opening and closing pockets. The two hard-sided shells may be utilized to form a primary compartment. One or more other hard-sided shells may be utilized to faun secondary compartments as well.

Notably, the shells 20 may be comprised of a thermoplastic composition or other similar composition. In an embodiment, the shells may be comprised of a polycarbonate composition, which may include adding one or more other substances to the composition such as ABS plastic. The polycarbonate composition may enable the shells to be flexible, while maintaining a generally rigid form. When stressors are applied to the shells, the polycarbonate composition may allow the shells to absorb the impact from the stressors and cause the shells to flex to accommodate the stressors. After the stressors have been remove, the polycarbonate composition may enable the suitcase to return to its original shape.

The hard-sided shells 20 may be connectable to one another through the use of an opening zipper 30 or other fastening mechanism such as, but not limited to, snap fasteners, buttons, and buckles. Each side of the zipper 30 may include a plurality of metal or plastic teeth, which may be stitched or otherwise attached to corresponding pieces of fabric tape. The fabric tape may be comprised of ballistic nylon or other similar materials. One fabric tape may be stitched or otherwise fastened to an edge of one of the hard-sided shells and the other fabric tape may be fastened to an edge of another hard-sided shell. The zipper 30 may include one or more sliders 35, which may be configured to hold at least a portion of the plurality of teeth on each side of the zipper mechanism. Once the slider 35 is slid across the plurality of teeth, it may be utilized to connect the edges of the hard-sided shells together, which forms a seal for the storage compartments within the shells.

In one embodiment, the zipper 30 may be slid across the entire edges of the hard-sided shells 20. Such a configuration would allow the compartments to be entirely or almost entirely separated upon completely unzipping the edges from one another. However, in another embodiment, the suitcase may have a hinge 40 (shown in FIG. 2), preferably along the bottom portion of the suitcase. The hinge may permanently connect at least a portion (such as the bottom portion) of the edges of the hard-sided shells together. The remaining portions of the edges that are not connected by the hinge may be connectable via the zipper mechanism. By utilizing the hinge, this may allow the hard-sided shells to remain at least partially connected to one another, particularly in the event that the zipper mechanism fails. In some arrangements, the hinge may be formed of a hard nylon, or plastic material.

As shown in FIG. 2, the interior of the back hard-shell 20 may be smooth and/or generally flat. The interior of the back hard-shell 20 may be devoid of any components or arms associated with a handle, such as a telescopic handle 50. As a result, the size of the main storage compartment may be enlarged.

The suitcase 10 may include one or more handles for carrying, pulling, pushing, and/or lifting the suitcase. The handles may include a rigid, telescoping handle 50 which may have a push button lock. The telescoping handle 50 may be connected to a top portion or other portion of a hard-sided shell so as to allow for easy transportation of the suitcase. The handle may include trolley tubes, which may extend through a portion of the hard-sided shell to which it is attached. This may allow for additional structural support and allow the handle to undergo a greater amount of stress.

In one embodiment, the trolley tubes may be encased within the storage compartment into a protrusion along the backside of the hard-sided shell. The encasing may be performed laying a fabric, plastic, or other material across the trolley tubes so as to ensure the flat surface. Once the trolley tubes are encased, a flat surface may be created across the trolley tubes. This allows one to pack the compartment of the suitcase without having to pack around the trolley tubes, while also ensuring a more uniform compartment space. One may also pack between the trolley tubes. One or more carry handles 60 may also be included. For example, on a large suitcase two carry handles 60 may be provided, one on the top of the suitcase 10 and one on a side thereof.

The suitcase 10 may also be configured to include a plurality of wheels 70 for transporting the suitcase. In one configuration, two wheels 70 may be connected to a bottom portion of a hard-sided shell, preferably along the opposite ends of the bottom of the shell. In another configuration, another set of wheels may be connected to a bottom portion of another hard-sided shell so as to allow for four wheels positioned at the four ends of the bottom of the suitcase.

Any number of wheels and any position for placement of the wheels may be utilized as well. For example, one wheel may be placed on a bottom portion of one hard-sided shell and two wheels may be placed on a bottom portion of another hard-sided shell. Such a positioning may allow for greater stability and for easier transportation of the suitcase 10. In an embodiment, the wheels may be plated with chrome or another similar material. Plating the wheels with chrome or other similar materials may enable the wheels to rotate along a variety of surfaces in a smooth and easy motion by minimizing friction and drag along the surfaces. In another embodiment, the wheels may be hub cap plated. The wheels may be manufactured from rubber, nylon, plastic, metal, or other materials. The wheels may have packed or other types of bearings to facilitate rotation.

The suitcase 10 may be configured to have one or more expandable portions 80, which may be utilized to expand one or more storage compartments of the suitcase. The expansion portion 80 may comprise a fabric expansion gusset 84 and a polycarbonate composite expansion shell portion 86. The gusset 84 may be made of ballistic nylon or other similar materials, particularly materials which allow for flexibility. The expansion shell portion 86 may be connected to at least one of the hard-sided shells 20 at an edge of the shell 20. Notably, the expandable portion 80 may be secured in a non-expanded state by utilizing an expansion zipper 90 or other similar securing mechanism, which may be connected between an edge of one shell 20 and the expansion shell portion 86 with the expansion gusset between the two sides of the zipper 90.

When an individual pulls a slider 95 to open the expansion zipper 90, the expandable portion may expand so as to increase the storage capacity of the suitcase. For example, the expandable portion 80 may allow the storage capacity of the suitcase to be increased by 10-25%. If the individual would like to return the suitcase to its original size, the individual may close the zipper 90 using its slider mechanism 95, if necessary while applying force or sitting on one of the shells 20. This may enable the two shells 20 to compress the contents of the suitcase down to a smaller size if desired, or the user may travel with the suitcase 10 in the expanded configuration.

The expansion shell portion 86 may include a honeycomb or other plastic frame portion 100 (shown in FIG. 3), which may be positioned on an interior side of the expansion shell portion 86. The frame 100 may be screwed and/or riveted to the polycarbonate expansion shell portion 86, and may be covered with a nylon or other fabric lining so as to hide the frame from direct view. The frame portion 100 may provide additional strength to the expansion shell portion 86.

Notably, the expansion shell portion 86 may be located at approximately the midpoint of the width of the suitcase 10, and supports at least one of the carry handles 60, preferably supporting two carry handles 60, one on the top of the suitcase and one on the side of the suitcase. This may provide several advantages. First, the expandable portion 80 and the shell 20 to which it is attached form a deep receptacle for packing clothes into. This may make for easier packing and closing of the suitcase 10 than with a suitcase formed of two equally-sized shell portions. Second, the carry handles 60 may be provided at the midpoint of the suitcase, which may make for easier weight distribution and carrying of the suitcase. Such positioning of the handle may allow an even-balanced, level lift of the suitcase when an individual decides to transport the suitcase. The frame portion 100 attached to the expansion shell portion 86 may provide sufficient strength to prevent buckling of the expansion shell portion 86 as the weight of the suitcase may be carried by the carry handle 60.

In one embodiment, the suitcase 100 may include a locking mechanism for preventing unauthorized access to one or more compartments of the suitcase. The locking mechanism may be a conventional lock and key mechanism, a combination lock, a key code lock, a radio frequency identification lock, or other types of locks. Additionally, the locking mechanism may be a biometric lock, which, for example, may be configured to read fingerprints or other physical identifiers.

In one embodiment, aluminum side frames may be attached to the outside of the suitcase 10, both for a decorative look and to protect the edges of the suitcase from knocks during transit. Other side frames may be used, including those made from other types of metal or other materials.

III. Additional Exemplary Embodiments

In general, a hard-sided suitcase may have a front and a back hard-sided shell that together comprise a main storage compartment. A telescopic handle may having retractable or extendable arms, corresponding tubes configured to house the arms, and a curved handle. The tubes of the telescopic handle may be fully or partially encased within the back hard-sided shell. As a result, the tubes may be substantially or approximately flush with the exterior of the back hard-sided shell, and the interior of the back hard-sided shell may provide a smooth and continuous surface to the main storage compartment to alleviate the need to pack around or over any fixed tubes or other components of the telescopic handle during use. The curved handle may be configured to fit into or within a corresponding curved and/or indented surface on the top, back corner of the back hard-sided shell. The top and backmost portions of the curved handle may be substantially or approximately flush with the exterior surfaces of the back hard-sided shell.

More specifically, in one aspect, the hard-sided suitcase may provide a back hard-sided shell that at least partially encases the frame and/or fixed tubes of a telescopic handle. The frame or fixed tubes may remain partially visible when viewing the exterior of the back hard-sided shell.

For example, the hard-sided suitcase may include front and back hard-sided shells defining a main storage compartment. The hard-sided suitcase may include a telescopic handle having retractable arms, a handle, and fixed tubes. The retractable arms may be configured to extend into and out of the fixed tubes. The fixed tubes of the telescopic handle may be at least partially encased within, and immovable with respect to, the back hard-sided shell such that the backmost portion of the fixed tubes may be substantially or approximately flush with a backmost exterior of the back hard-sided shell, while still remaining visible. Simultaneously, a smooth and continuous surface may be provided by, or on the surface of, the interior of the back hard-sided shell that faces toward the main storage compartment to facilitate the packing of clothing and other articles within the main storage compartment without requiring packing around any fixed tubes or other components of the telescopic handle that protrude from the back hard-sided shell and into the main storage compartment.

In another aspect, the hard-sided suitcase may include a telescopic handle having a curved handle.
