BACKGROUND

Field of the Invention

This invention relates to suitcases, carrying cases and backpacks (collectively “luggage”), as commonly used by travelers, hikers, or passengers for the protected transport of, access to, and removal/replacement of, articles of clothing and accessories.

Description of the Related Art

A unit of luggage ordinarily comprises a front panel, rear panel, a right side panel, a left side panel, a top panel and a bottom panel. The bottom face is normally comprises a rigid base. A storage space is positioned between the top, bottom, front, rear, and side panels. A means is provided to allow access to the internal storage space. Two or four wheels are often fastened to the bottom face. An expansion mechanism can be constructed and arranged to expand the storage space. Many bags have external carrying and collapsible handles for mobility and external zipper pockets. Some also have external zipper pockets and elastic straps or cords.

Trains, buses, oxcarts, and personal vehicles permit luggage of almost any size and shape, so luggage that is acceptable for commercial air transport will also be suitable for transport by virtually all other means.

Luggage including suitcases, backpacks, handbags and duffel bags (“luggage”) is typically sized and shaped to support convenient storage and transport of personal goods, in sizes that are allowed or required for air travel in cargo holds or in overhead compartments. In that regard, luggage may be carried into the cabin of an airplane, or checked in for transport in the luggage or freight compartment of an airplane. In the case of carried-on luggage, most airlines have volume requirements such that luggage must fit within airline-specified height, width and/or length requirements along with weight limitations

Most luggage (backpacks, suitcases, etc.) is designed to be transported in a vertical upright position whether on wheels or on the body. However, luggage is normally packed with the luggage in a horizontal position with a flap or upper piece designed to open on three sides to fully expose the interior of the luggage to facilitate packing and unpacking. Backpacks and some luggage are packed in a vertical position with a top panel flap opened to expose the interior. Most suitcases are loaded by opening the front face while the container is in a horizontal position. Many backpacks and some cases are loaded from the top after opening a top flap and exposing the interior. The contents of luggage and backpacks are packed on top of each other in order to fill the luggage to its desired capacity. Once packed, the luggage is positioned vertically for transport as most suitcases and many other luggage items have wheels mounted on the bottom. The backpack is similarly positioned vertically for transport utilizing straps attached to the rear panel of the backpack which are designed to fit over one's shoulders. At destination, the luggage is placed in the horizontal position and the front panel opened to expose and access the interior contents. The backpack is placed on its bottom and the top flap opened to expose and access the interior contents. Access to any item on or near the bottom of the luggage or backpack requires removal of all items on top. Once the desired item is retrieved, the removed items must be either stored elsewhere or replaced in the luggage, bag or backpack. At each destination, this sequence of unpacking and re-packing is repeated. In order to access and retrieve any particular item, other items must be removed and replaced or stored in another location.

A disadvantage of the existing luggage or backpack configuration is that, at each destination, in order to access any desired particular item, other items atop the desired item must be removed. Frequently, the luggage is unpacked, the contents temporarily stored in drawers or closets and then re-packed when departing. To avoid constant removal and replacement of individual items, the luggage contents are frequently unpacked and temporarily stored in drawers or closets for retrieval and replacement. Upon departure, all items must be re-packed and the opening closed and secured. Alternatively, removed items are replaced in the luggage or backpack. Retrieval of any particular item by the user requires a repetition of the removal of layers of packed clothing or accessories. When empty and not in use while traveling, the luggage must be stored. Even when empty, large suitcases occupy significant space in some storage area such as a closet, room corner, under a bed, or garage. Empty luggage serves no utilitarian purpose when stored and not in use. Prior to a departure, the luggage must be retrieved from storage, re-packed and closed before transportation.

There is a need for a suitcase, bag or backpack to not only serve as a carrying method for items in transit but also as a storage, retrieval and replacement means for items at destination, configured to assist in retrieval or replacement of carried items. Luggage that permits immediate retrieval and replacement of items of clothing and travel accessories saves time and effort, increases the utility of the luggage, and permits organization of carried items.

Due to the increased use by travelers of travel documents and accessories including electronic documents and portable electronic devices, access by travelers is generally restricted to front or side pockets. Access is restricted when the luggage is in the horizontal stored position. Removal and replacement of the luggage is necessary for access. This becomes particularly cumbersome when the luggage is in an overhead storage compartment. This is exacerbated when the transportation conveyance is in motion particularly during air turbulence or on uneven surfaces. Document retrieval and charging is facilitated and safer if access is easily provided whether the luggage or backpack is in the vertical or horizontal stored position. Easy access to travel documents and battery charging devices during actual transit without removal and replacement of the luggage promotes safety and saves time. Top panel superimposed pockets containing travel documents (such as passports, boarding passes, etc.) and a battery charging device with cables offers convenient access whether the luggage is vertical or horizontal (such as stored in an overhead luggage rack). Removal and replacement of such luggage from overhead storage compartments or racks is mostly eliminated.

The typical luggage contains a fixed flap permanently attached to the luggage on at least one edge. Toiletries and other grooming and dressing items are generally packed in the interior space. They must be removed from the interior space of the luggage and carried to the place of use. These accessories include hair dryers, curlers, shavers, etc. This necessitates successive trips between the luggage and the place of use. Following use, these items must be replaced for transport or re-use.

Re-packing of the pouches requires assembly, moving them to the site of the luggage and fitting them into the luggage. A disadvantage of typical luggage configurations is the lack of a dedicated detachable compartment for toiletries and grooming items which could be contained in a detachable compartment, removed for use and then replaced for transit. If a detachable compartment could be hung on a hook or bar, the contents would be readily available at the point of actual use.

SUMMARY

In one embodiment, a luggage system is disclosed. The luggage system maximizes storage space in a fixed size luggage. It permits safe access to transit items (boarding passes, reservation documents, tickets, etc.) from luggage in a horizontal (stored) position when in motion without removing and replacing the luggage. Especially the present invention provides convenient access to individual desired items without removal, temporary storage and re-packing of other contents. It provides a usable computer work surface during transit waiting periods. It provides a detachable portable briefcase and eliminates the necessity of carrying a separate briefcase during transit. It provides a convenient electronic charging device during transit periods when power outlets are not available. It eliminates repetitive unpacking and temporary storage (in drawers, closets or bathrooms) at intermediate destinations. It eliminates re-packing of clothing and accessories prior to departure. It eliminates the temporary storage of empty suitcases at intermediate destinations. It saves time and effort in accessing and replacing individual clothing items and travel accessories. It provides a carrying method during transit but also a storage and retrieval method at each destination. It permits access and utilization of clothing and accessories at the place of actual use at intermediate destinations without removing and carrying the items to the place of use and then returning and replacing them into the luggage. It saves time and minimizes effort in packing, accessing, removing and replacing clothing and travel accessories. It facilitates the transit of luggage over uneven surfaces by providing an optional detachable method of carriage as a backpack. It permits easy removal and replacement of detachable exterior pockets. It combines a travel storage container, a briefcase and a liquid container carriage into a single integrated unit eliminating the need to carry three separate items.

Given the limitations of convenient access to travel documents, electronic device charging components, the large undivided luggage or backpack interior, the necessity of removing multiple items from the interior to access a single desired item, the lack of utility of an empty suitcase, the present invention provides (i) convenient access to travel documents and charging battery during transit in the vertical or horizontal position, (ii) storage and access to items of clothing and travel accessories on detachable and adjustable zipper cloth shelves, (iii) detachable toiletries pockets to be separately detached, (iv) an expandable front panel to be detached and hung on a hook or bar during use, (v) storage of bulky, wet or soiled items in a waterproof detachable bottom zipper faced pocket, (vi) elimination of the necessity of unpacking and re-packing at each destination in order to access luggage contents, and (vii) a detachable briefcase.

This application describes an improved luggage bag with external locking zipper pulls, superimposed top panel storage pockets, side panel elastic straps and pockets, an expandable, detachable and suspendable front panel with middle internal hook and loop fastened pockets for toiletries and grooming accessories, front panel interior elastic buckle strap, front panel interior pockets for clothing, top and front panel elastic cords, interior space detachable and vertically adjustable reinforced interior zipper edge stretchable cloth shelves for easy storage, retrieval and replacement of single items of rolled or folded clothing or travel accessories, a detachable waterproof zipper front bottom pocket for storage of bulky items, soiled or wet clothing and personal travel items, and a detachable briefcase.

The luggage system enables travelers to (i) secure contents with external locking zippers, (ii) utilize external elastic straps on a side panel for temporary storage during transit, (iii) utilize the top front panel pocket as a fold down work surface, (iv) access travel documents and device charging battery from superimposed top panel pockets while the luggage is in the vertical or horizontal (stored) position (v) temporarily store travel items under exterior elastic cords on the top and front panels during transit, (vi) detach, transport, and hang the front panel for access to its contents at point of use, (vii) easily store and readily access individual items of rolled or folded clothing and travel accessories on detachable, vertically adjustable interior zipper stretch cloth shelves and (viii) store bulky, wet or soiled items in a waterproof detachable bottom zipper faced pocket.

In some embodiments, the luggage system may comprise interior detachable and vertically adjustable shelves that eliminate packing items on top of one another. Rolled or folded items of clothing are placed on separate shelves. All items are visible upon opening the flap. Any particular item is retrievable from its shelf without removal or disturbing other items.

The luggage system eliminates the necessity of empty luggage storage. Emptying the contents becomes an option for the user. For example, in extended stays at any particular destination, the user may, if he or she chooses, empty the luggage contents and utilize existing drawer or closet space. For shorter stays, or for destinations where storage space is minimal or non-existent, the presently disclosed luggage is a traveling chest of drawers. Unpacking the entire contents becomes unnecessary and may be eliminated. Storage of the empty luggage becomes unnecessary.

The presently disclosed luggage contains a detachable front panel with toiletries and grooming items in pockets secured to the interior front panel with hook and loop fasteners. Larger grooming items such as hair dryers, curling irons and electric razors are secured with elastic straps on the middle of the interior front panel.

When the front panel is opened and lowered or detached, the luggage operates as an open-front chest of drawers eliminating the need to unpack or remove top layers of clothing to access any desired article. The entire interior space contents are visible at a single glance. The internal volume of the bag is divided into multiple spaces by zipper edged stretchable cloth shelf dividers. The vertically adjustable cloth zipper shelves permit maximum organizational utility, flexibility and instant access and replacement of interior contents. Removal or other items to retrieve a particular item is eliminated. Re-packing the luggage before departure is eliminated. The space occupied by and lack of utility of empty luggage is eliminated. Traveler convenience is facilitated. Time is saved.

Provided herein is a design for luggage or backpack that can conveniently be accessed during transit, eliminates the need to unpack at each destination, eliminates content spillage when opened vertically, and enables the user to access and replace individual items on detachable, adjustable and stretchable cloth zipper edge interior shelves. When opened, the luggage or backpack becomes an open front chest of drawers. The need to temporarily store an empty suitcase or backpack is eliminated. In addition, it permits storage of bulky, wet or soiled items in a waterproof detachable interior zipper front pocket.

In one embodiment a luggage system is disclosed. The luggage system comprises a rollable upright stiff-sided travel suitcase or backpack comprising: superimposed exterior top pockets, an exterior upper front folding pocket, an exterior lower front pocket, an open ended separating locking zipper exterior front opening fold down detachable front panel, exterior side pockets, elastic cords on the exterior front and sides, having interior detachable and vertically adjustable clothing and accessory spaces using open ended separating zipper-edged stretch cloth shelves attached to vertically pre-spaced corresponding separating zippers for placement and retrieval of items.

The case is designed for organized storage and retrieval of clothing and travel accessories. When the front panel is folded down or detached, the entire contents are visible and accessible. Like items of clothing are either rolled or folded and then inserted into separate shelf compartments. Pockets containing toiletries and grooming items inside the detachable front panel are removable for inspection or use and replaceable and secured inside the detachable front panel for transit. The entire front panel may either be detached entirely or simply unzipped and folded down for access to the contents.

The luggage contains an interior space designed to hold personal good/belongings such as clothing, personal effects, travel accessories and the like on stretchable, detachable and vertically adjustable zipper edge cloth shelves. A typical piece of luggage therefore has a body with a closure on a portion thereof for opening and closing the body to allow insertion and removal of articles into and from the luggage. The term “luggage” is derived from common, historical use in which an article of luggage was literally lugged or carried from one location to another for the transport and/or storage of personal goods. Typically, use of luggage is associated with travel, in which luggage is used to store and/or transport personal goods while traveling by automobile, bus, train, airplane, ship and other forms of transportation and while staying at a destination away from home.

The present disclosed luggage relates to exterior superimposed top pockets, lockable zipper slide pull tabs, exterior expandable, detachable and hanging front panel, detachable and vertically adjustable interior zipper edged stretchable cloth shelves, an interior bottom detachable waterproof zipper edged pocket and rear panel with optional side release receiver buckles at each corner to mate with side release insertion buckles enabling the luggage to be transported as a backpack. As used herein, the term “luggage” is used in the ordinary sense of the word, and is synonymous with carrying case, suitcase, travel bag, backpack, and so forth. Luggage accordingly refers to an article that has a box, bag, and/or container like construction with a top panel, bottom panel, front panel, rear panel, right side panel and left side panel.

An additional feature of the presently disclosed luggage is a superimposed top pocket designed to contain an electronic power bank or charging battery with charging cords housed within the top pocket and the cords extended outside the pocket by means of a snap close end flap. In this way, the luggage can conveniently serve as a source for charging one or more electronic devices such as a cell phone, tablet, computer and so on. The electronic power bank can be utilized with the luggage in the vertical or horizontal position. The pocket can hold cords with charging ports usable as charging outlets for charging electronic devices and for re-charging the electronic power bank or battery. The power bank or charging battery may be utilized with the power bank or battery inside the pocket. A small snap flap opening on the edge of the pocket permits the charging cord to be removed from the pocket and affixed to the device to be charged. Alternatively, the power bank or charging battery may be removed from the pocket and used or charged externally.

An additional feature of the presently disclosed luggage is a pocket on the top face of the luggage, underneath the electronic power bank or battery pocket. This pocket with a lockable zipper pull is further divided into an outer and inner pocket. The outer pocket is designed to hold travel accessories useful or necessary during transit. The inner pocket contains an elastic edge top inner cloth pocket fastened on each edge and at the bottom. The inner pocket is designed to hold travel documents and other items useful or necessary to the traveler during transit. For example, this inner pocket can contain travel documents such as boarding passes, passports, visas, health certificates, customs declarations and the like. A preferred feature of the location and utility of the outer and inner top pockets is that the contents may be accessed whether the luggage is in the vertical or horizontal position. For example, while a luggage of the requisite size for airplane carry-on and overhead storage, travel documents and other travel accessories useful or necessary during transit may be accessed, retrieved and replaced while the luggage is in a horizontal position in an overhead storage compartment. The cumbersome and potentially dangerous process of removal and replacement of the entire luggage while the conveyance is in motion in order to retrieve a single travel document or accessory becomes unnecessary.

While the present embodiment has been described as having particular configurations disclosed herein, the present invention can be further modified within the spirit and scope of this disclosure. This application is, therefore, intended to cover any variations, uses or adaptations of the invention using its general principles. Further this application is intended to cover such departures from the present disclosure as come within the known or customary practice in the art to which this invention pertains.

The top panel of the suitcase contains two superimposed closed end lockable zippered upper and lower pockets (see FIG. 2). The bottom pocket is an accordion side, top opening pocket opened by a closed end lockable zipper slide located on the top and side edges adjacent to the top carrying handle. The superimposed upper pocket comprises a smaller pocket with a closed end lockable zipper slide located on the top edge on the opposite side of the carrying handle. On one edge is a small snap close opening flap allowing extension of a charging cable. This upper pocket holds an electronic device charging battery and charging cables.

An elastic cord is secured to the exterior top panel extending along the front, left, and right edges of the top panel. At the rear of the exterior top panel, the elastic cord extends from the left edge to the right edge between the collapsable handle and the carrying strap. The elastic cord is secured at each of the top panel corners by a rivet at each corner. Articles of clothing and travel accessories may be inserted under the elastic cord during transit.

The top bottom pocket facilitates storage of en-route travel documents and accessories useful to the traveler during transit (the “Transit Items Pocket”). The contents of the top pocket are easily accessed when the bag is either upright or stored horizontally (such as in an overhead luggage compartment) without retrieval and replacement of the luggage. This expandable pocket is designed to hold travel documents and accessories normally used during transit. These include passport, tickets, boarding documents, health certificates, itineraries, reservation information and other accessories including cell phones, ear buds, inflatable pillow, eye coverings, lotion, eye drops, toothbrush and toothpaste, comb or small brush or other accessories normally utilized during transit. The top pocket (of the design example) is located toward the front between the fixed center carrying handle and the front edge. Each side of the pocket expands when zipped open to facilitate insertion and removal of items. The zipper pull tab (or slide) combination lock contains a small cylindrical hole. When closed the pull tab is secured to a matching cylindrical rod extending ½ inch beyond the leading edge of the fixed zipper stop. When closed, the rod at the fixed stop inserts into the cylindrical hole in the in-line combination lock acting as the zipper slide. This prevents access to or retrieval of the contents until the correct combination is set and the zipper slide is moved to the open position.

Inside the bottom compartment is a smaller fabric pocket fastened on 3 sides and opened on 1 side with an elastic edge. This permits the separation of and facilitates access to documentary transit items such as tickets, boarding passes, itineraries, maps, passports and the like. Access to this pocket is obtained when the bottom pocket is opened. They may be accessed more conveniently and directly by the user. Access to this compartment is obtained by expanding the elastic top strap. By locating this pocket on the top of the luggage, access to those items normally used during transit is conveniently facilitated when the luggage is either standing upright, rolling, or placed in an (airplane, train or bus) overhead storage compartment. Access to the contents is achieved without removal, relocation or replacement of the entire luggage from the storage compartment. See FIG. 2.

Superimposed upon the top bottom pocket is a smaller accordion sided upper pocket designed to contain a portable electronic device charging battery and device charging cords. The pocket is accessed by means of a closed end lockable zipper slide opening located on the edge opposite the extension handle at the back. On one side of this pocket is a small snap close flap opening enabling the user to pull a charging cord end from the opening when in use. Inside the pocket is sufficient space for a device charging battery and charging cords for the devices and charging battery. The charging cords are coiled and placed inside the pocket. One end of the charging cord is inserted into the charging battery socket and the other end may protrude through the snap flap opening on the side of the pocket cover when in use. These rechargeable device charging batteries may be removed along with device charging cords as desired.

The pocket size and shape allow insertion of a removable electronic battery charging device and charging cords. This permits the user to charge electronic devices while they rest upon the top of the luggage during transit. Alternatively, the extra cord on the charging device may be utilized to plug into any charging receptacle (e.g., a plug or USB port) for re-charging the battery charging device. The charging device may also be accessed when the luggage is in the horizontal position such as on an overhead storage rack or compartment during transit.

The bottom panel is a rigid panel which, in the preferred configuration, comprises four (4) 360 degree spinner wheels located at each corner and six (6) stabilizing knobs located two (2) each on the rear edge, front edge of the luggage container and the front end of the detachable front panel.
