Description

BACKGROUND OF THE INVENTION

[0001] 1. Technical Field

[0002] The present invention relates to luggage employing a handle and wheels. More particularly, the invention relates to luggage employing a rotatable handle, wheels allowing movement on two distinct axes, and support shafts located on the sides of the luggage.

[0003] 2. Description of Related Art

[0004] In traveling, articles of luggage that are often large and/or heavy are often difficult to move. To make it easier to maneuver such articles of luggage, prior art designs have incorporated casters such as rollers or wheels located on a relatively planar surface. With casters, the luggage may then be rolled as opposed to being carried or rolled with a separate mechanism such as a cart.

[0005] A first common design of luggage incorporates casters on one of the longer, narrower sides of essentially parallelepiped articles. With this design, the luggage may be towed while in a customary standing position. To maneuver this type of luggage, a handle or cord is typically provided so that a user may tow the article.

[0006] One improvement for rolling luggage, particularly for frequent travelers, locates casters on one of the shorter, narrower sides with a handle disposed on the side opposite to the casters. Thereby, a user may tow the luggage with the article being supported by a handle and by casters being rolled upon a substrate. These types of prior art luggage generally have a handle that may be extended out from the top of the article for rolling. The supports for this handle structure are known to longitudinally extend internally along a central portion of the article of luggage. The disadvantage of the centrally disposed support is that it consumes space within the article of luggage. This often causes items packed within the luggage to become wrinkled when packed adjacent to the support structure. Also, these types of prior art luggage can be difficult to maneuver through narrow passage ways such as an airplane aisle.

[0007] Therefore, it is desired to construct an article of luggage that allows a user to alternate rolling positions for easy maneuverability. One position would be optimal for moving over larger distances at a relatively fast pace. Another position would be optimal for moving through narrow passages. It would be further desirable to allow a user to easily switch between rolling positions. Another desired aspect for an article of luggage would be to avoid having a centrally disposed support structure for the handle.

SUMMARY OF THE INVENTION

[0008] The luggage of the present invention comprises a generally parallelepiped container having a front elongated segment, a back elongated segment, a first side segment, a second side segment, a top segment, and a bottom segment. The first and the second side segments are disposed along side portions of the container between the front and the back elongated segments and between the top and the bottom segments. A first support is affixed longitudinally to the first side segment. Also, a second support affixed longitudinally to the second side segment. A handle assembly containing a handle is disposed above the top segment. Therein, the handle assembly operatively engages the first and the second supports. For moving the luggage, a set of casters affixed on the bottom segment whereby the container may be rolled with a leading segment set at an incline relative to a substrate supporting the container wherein the leading segment may be one of the elongated segments or one of the side segments.

[0009] In use, the luggage as described above is set upon the casters that are supported upon the substrate. When the user is ready to move the luggage, the user extends the handle away from the top segment. Thereafter, the luggage may be rolled to a desired destination. Generally, the luggage would be rolled with an elongated segment as the leading edge until a narrower pathway is encountered such as an airplane aisle. When the narrower pathway is encountered, the luggage's leading edge may be switched to one of the side segments allowing easier passage.

[0010] With the movable luggage of the present invention, several advantages are obtained. First, the luggage with the same general dimensions as compared to prior art luggage having embedded centrally located support shafts has additional space available in its interior. Also, the side of the invention produces a more robust design compared to luggage with centrally located supports. Another advantage realized with the use of side supports is that a large flat central side against which items that are desirably not to be wrinkled may be packed. Further, luggage in accordance with the present invention employ a wheel and handle system that allows a user to easily maneuver the luggage over a variety of distances and terrain and through narrow passages such as an airplane aisle.

DETAILED DESCRIPTION

[0016] Referring to FIGS. 1 and 2, a piece of luggage 10 has sidewalls 12 and 13, central sides 14 and 15, top side 16, and bottom side 18. While luggage 10 is shown generally as a suitcase in the shape of a parallelepiped, it is understood that luggage in accordance with the present invention may comprise other shapes such as, for example, a tube or cube. Also, luggage of the present invention may comprise other types of baggage such as, for example, duffle bags, back packs, trunks, and cases. As to the composition of luggage 10, it may comprise either a hard-sided or soft-sided construction being made of materials such as fabric, plastic, metal, or combinations thereof. For entry to the storage compartment of luggage 10, a zipper or one or more fasteners may be provided in as in other conventional luggage.

[0017] Disposed on bottom side 18 are wheels 20, 22, 24, and 26. Wheels 20 and 22 are provided on bottom side 18 proximately to the corners of luggage 10 at the intersection of sidewalls 12 and 13 with central side 15. Similarly, wheels 24 and 26 are provided on bottom side 18 proximately to the corners of luggage 10 at the intersection of sidewalls 12 and 13 with central side 14. In addition to wheels as shown, wheels 20, 22, 24, and 26 may also comprise rollers, casters, and the like.

[0018] Optionally, wheels 20, 22, 24, and 26 may be of a swivel type allowing freedom or at least partial freedom for each wheel to rotate upon its axis. This is advantageous for maneuvering luggage 10 considering that luggage 10 when being towed is generally supported by only two wheels. While shown luggage 10 is shown having four wheels, other embodiments are possible such as only a three wheel arrangement with the fourth wheel being replaced by a support peg for luggage 10 in an upright, non-towing position.

[0019] Another optional embodiment is to employ one or wheels 20, 22, 24, and 26 with one directional brakes. Employing one or more wheels with these brakes allows a user towing luggage 10 to retain the luggage in a tilted position resting on two wheels without the need to prevent luggage 10 from rolling backward away from the user. Thereby, a user will not tire as easily while waiting in lines, which are common in travel.

[0020] Affixed to sidewalls 12 and 13 are supports 30 and 32, respectively. Supports 30 and 32 are disposed longitudinally along the periphery of sidewalls 12 and 13. FIG. 3 shows one embodiment of a support having a bracket shape to provide structural robustness while utilizing a minimal amount of material. Therein, a cross section of support 30 is square bracket-shaped wherein side 33 faces outward from sidewall 12 and attachment portion 37 is affixed to sidewall 12. While not shown, support 32 is identical in construction to support 30 and is affixed to sidewall 13. While a bracket shape support is shown, other conventional shapes may be used for the supports such as a channel with a round or rectangular shape.

[0021] Handle assembly 38 has a telescoping portion 34 in a preferred embodiment. Therein, supports 30 and 32 have an opening 35 for receiving telescoping portion 34. Telescoping portion 34 may be of similar design and shape to that of supports 30 and 32 except for being smaller. Essentially, telescoping portion 34 can fit within supports 30 and 32 when in a retracted position. When in an elongated position, telescoping 34 is extended out and away from supports 30 and 32 until terminal ends of telescoping 34 are nearly planar with top side 16. Handle assembly 38 may be provided with one or more locking mechanisms (not shown) to retain telescoping portion 34 in the fully extended position (shown in FIGS. 1 and 2) or in its retracted position (not shown). The lock mechanism may be of any suitable type such as a spring loaded button or latch.

[0022] With supports 30 and 32 being disposed longitudinally along the periphery of sidewalls 12 and 13, supports 30 and 32 may be significantly wider than typical supports which are disposed centrally within prior art luggage. With a wider support, sidewalls 12 and 13 approximate a planar surface allowing for easier storage and handling. Hence, a more robust handle support system is realized by the present invention.

[0023] A further advantage realized by locating the supports along the sidewalls is the availability of a large flat central side 14 or 15 where supports of the prior art luggage are generally located. A large flat central side is often very desirable in travel because it keeps items such as drawings, documents, clothing, and the like from getting wrinkled. Also by locating supports on the sidewalls, more storage space is available inside the luggage as compared with centrally disposed supports used in prior art luggage.

[0024] For luggage such as a wheeled backpack, having the supports along the sides has the additional advantage of being more comfortable to wear. Prior art backpacks employing centrally located supports cause wearers discomfort because the weight of the backpack is transferred to the wearer through relatively narrow support bars. With the support on the sides, the backpack in accordance with the present invention has an essentially planar back that allows the weight of the pack to be disbursed over a wider area.

[0025] Between opposing telescoping portions 34 is a top support 36 of handle assembly 38 having a handle 40 centrally disposed thereon. Handle 40 in the embodiment shown in FIG. 1 is parallel and in alignment with top support 36. This is useful when the luggage 10 is being towed with its wider side, shown here as central side 15, being transverse to the direction of travel. As shown in FIG. 2, handle 40 may be positioned perpendicular to top support 36. This handle alignment is useful when luggage 10 is being towed with its narrower side 13 being transverse to the direction of travel. Optionally, handle 40 may be constructed with a ridged or other suitable design so that a hand may comfortably engage it. While FIGS. 1 and 2 show central side 15 and sidewall 13, respectively, as being the leading sides in the direction of travel, central side 14 and sidewall 12 may also be capable as being leading sides in other embodiments.

[0026] Advantageously, handle 40 may be rotatable to allow easier conveyance. FIG. 4 shows one construction of a mechanism to allow handle rotation. On a top portion of handle 40, several bumps 46 are disposed about a central spring 48. Within recess 42 of top support 36 are corresponding notches (not shown) for receiving bumps 46. Thereby, handle 40 may be securely retained in a desired position when bumps 46 and their opposing notches are engaged. When a user desires to rotate handle 40, release button 44 is pushed causing spring 48 to release tension. Thereby, the user may rotate handle 40 to a desired position. While this construction shows an example of one type of locking arrangement, other types are possible such as a latch.

[0027] In operation, luggage 10 would be set upright with bottom side 18 facing a foundation such as a floor or ground. A user may then determine the most effective mode of moving luggage 10. A first mode may include leaving handle assembly 38 in its retracted position allowing the user to lift luggage 10 up from the foundation using handle 40. This may be beneficial when moving luggage 10 a short distance or when placing luggage 10 into a vehicle or onto a baggage counter or cart.

[0028] A second mode of movement may include rolling, towing, or pushing luggage 10 while it is resting upon wheels 20, 22, 24, and 26. This may be done while handle assembly 38 is in either its retracted or extended position. A typical reason for moving luggage 10 using all four wheels would be while waiting in a ticket line where either lifting or tilting luggage 10 is inconvenient for moving the luggage only a short distance.

[0029] For the remaining modes, the user must extend handle assembly 38 away from top side 16. If luggage 10 is provided with a locking mechanism to retain handle assembly 38 in a desired position, a user would temporarily disengage the locking mechanism to allow extension. In another embodiment, the locking mechanism would only lock while handle assembly 38 is in its extended position allowing a user immediate capability to extend handle assembly 38 without the need to disengage a locking mechanism. Many types of handle extension mechanisms are known in the art and may be employed with luggage made and used in accordance with the present invention.

[0030] Once handle assembly 38 is in its extended position, a user may opt to tow or roll the luggage in a third or fourth mode of movement. With the third and fourth modes of movement, a user would apply force to handle assembly 38 causing luggage 10 to tilt to a desired side supported by two wheels. With the third mode, wheels 20 and 22 support luggage 10 as shown in FIG. 1. Optionally, the third mode may employ wheels 24 and 26 instead of wheels 20 and 22. In this third mode, luggage 10 is being conveyed with either central sides 14 or 15 being tilted toward the user. The fourth mode of movement would employ wheels 20 and 26 as shown in FIG. 2. Optionally, the fourth mode may employ wheels 22 and 24 as the support wheels instead of wheels 20 and 26.

[0031] As shown in FIGS. 1 and 2, central sides 14 and 15 are wider than sidewalls 12 and 13 in the embodiment shown. Conveyance of luggage 10 in the third mode allows for greater stability because of the increased distance between the moving wheels as compared to the fourth mode. The third mode would likely be employed to convey luggage 10 over greater distances or over less stable surfaces. The fourth mode would likely be employed to convey luggage 10 when travel space is limited such as within a narrow aisle on an airplane.

[0032] To allow easy conveyance of luggage 10 while in either the third mode or the fourth mode of travel, a user would position handle 40 into a desired orientation. To rotate handle 40, the user would depress release button 44 while rotating handle 40. Once handle 40 is rotated about 90 degrees, bumps 46 engage their corresponding notches within handle assembly 38 thereby locking handle 40 into its desired orientation. Desired orientations of handle 40 are shown in FIGS. 1 and 2.

[0033] With articles of luggage designed in accordance with the present invention, several advantages are realized. The support shafts of the present invention are located on the narrower sides as opposed to one of the wider sides. This allows the luggage to regain space lost to prior art luggage with centrally located supports. The side supports of the invention allow for much wider supports producing a more robust design compared to luggage with centrally located supports. Also, the use of side supports renders a large flat central side against which items that are desirably not to be wrinkled may be packed. Further, articles of luggage in accordance with the present invention employ a wheel and handle system that allows a user to easily maneuver the luggage over a variety of distances and terrain and through narrow areas such as an airplane aisle.

[0034] While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
