In general, the present invention relates to the structure of wheeled travel bags that are commonly used as suitcases or briefcases. More particularly, the present invention relates to wheeled travel bags that have some type of extendable platform incorporated into their designs that enables the bag to act as a table or similar support.
Many people travel with wheeled bags. The use of a wheeled bag eliminates the need for a person to lift the full weight of the bag. Rather, the bag can be simply pulled on its wheels as the person travels. Most wheeled bags have adjustable handles that can be extended when the wheeled bag needs to be pulled. In this manner, the handle can be retracted when the wheeled bag is loaded onto an airplane or into a car.
Wheeled bags are commonly used when a person travels. As such, the wheeled bag accompanies a traveler in airports, train terminals and the like. Many people who travel also travel with laptop computers and similar devices that allow the travelers to perform computer related tasks while traveling. In airports and other waiting stations, a traveler often cannot find an adequate work surface for the laptop computer. As a result, the traveler typically uses his/her lap and knees as support or tries to place the laptop upon the wheeled bag. Most wheeled bags have curved surfaces, handles, and other features that make it difficult to balance a laptop upon the wheeled bag. This causes the traveler to secure the laptop with one hand while operating the laptop with the other.
In an attempt to provide a better working surface, wheeled bags have been produced that have a folding platform attached to the pull handle of the wheeled bag. Such prior art rolling bags are exemplified by U.S. Patent Application Publication No. 2010/0187062 to Sweeney and U.S. Pat. No. 5,437,367 to Martin. However, such prior art platforms are attached to the pull handle of the wheeled bag, which creates one of two problems. If the platform is attached to the pull handle below the top of the pull handle, as in the Sweeney publication, then the platform and the pull handle meet at a right angle. When a laptop is placed on the platform, the screen of the laptop cannot be rotated beyond 90 degrees, due to the presence of the handle. As a consequence, the laptop cannot be fully opened and the screen of the laptop becomes difficult to see from many angles. Alternatively, if the platform is positioned at the top of the pull handle, as in the Martin Patent, then the pull handle cannot be grasped while the laptop is in place. As such, the laptop must be lifted off the platform in order to grasp the handle and adjust the position of the wheeled bag.
Another disadvantage of prior art platforms on wheeled bags is that the platforms typically fold away into the interior of the bag. As such, the presence of the retracted platform reduces the space available in the bag. Additionally, the platform serves no useful function when retracted. In many prior art designs, the bag needs to be partially emptied, unfolded and/or otherwise opened in order to access the retracted support platform. This is highly inconvenient, especially if the bag is fully loaded for travel and the traveler is in a public place.
A need therefore exists for an improved wheeled bag design that provides a retractable support platform and does not reduce the capacity of the bag when retracted. A need also exists for an improved bag design that has a support platform that does not restrict use of the bag handle when deployed nor limit the configurations of a laptop on the support platform. These needs are met by the present invention as described and claimed below.
The present invention is a travel bag assembly that utilizes a bag construct. The bag construct has wheels. When resting upon the wheels, the bag construct has a top surface that faces upwardly. A retractable pull handle is provided so that the bag construct can be conveniently pulled or pushed on its wheels.
A depression is formed in the top surface of the bag construct. The depression is an external feature and does not access the interior of the bag construct. A support platform is provided that either directly fits into the depression or can be folded to fit in the depression. The support platform is connected to the bag construct by at least one adjustable shaft. The adjustable shaft enables the support platform to be selectively adjusted in elevation throughout a range above the top surface of the bag construct without effecting the retractable pull handle.
For a better understanding of the present invention, reference is made to the following description of exemplary embodiments thereof, considered in conjunction with the accompanying drawings, in which:
Although the present invention travel bag assembly can be embodied in many ways, only two exemplary embodiments are illustrated. The two exemplary embodiments are being shown for the purposes of explanation and description. The exemplary embodiments are selected in order to set forth two of the best modes contemplated for the invention. The illustrated embodiments, however, are merely exemplary and should not be considered limitations when interpreting the scope of the appended claims.
Referring to
Lastly, the rear surface 18 faces the person who is pulling or pushing the travel bag assembly 10. Wheels 20 are attached to the bottom surface 14 and/or are positioned at the junction between the bottom surface 14 and the rear surface 18. In this manner, the bag construct 12 can be rolled with the wheels 20 or tilted onto the wheels 20 when the travel bag assembly 10 is in use. A retractable pull handle 22 is provided to assist in tilting and/or rolling the travel bag assembly 10. The retractable pull handle 22 is a traditional travel bag handle that can be selectively extended from, and retracted into, the bag construct 12. The shown example of the retractable pull handle 22 has two telescoping shafts 24 that extend from the rear surface 18 of the bag construct 12. The retractable pull handle 22 that is illustrated is intended to represent any and all of the many pull handle configurations used on comparable prior art wheeled bags.
A depression 30 is formed in the top surface 16 of the bag construct 12. The depression 30 has a peripheral shape that follows the shape of the bag construct 12. The depression 30 is an external feature of the bag construct 12, in that the depression 30 does not communicate with any compartment within the interior of the bag construct 12.
Referring to
When folded, the first panel 31 and the second panel 32 can be received within the depression 30 on the top surface 16 of the bag construct 12. As is indicated in
Referring to
From
In use, a person can open the bag construct 12 and fill it with anything they wish to transport. The overall travel bag assembly 10 can then be wheeled to a desired location. During travel, the support platform 36 can be locked in its retracted position within the depression 30 at the top of the bag construct 12. When needed, the support platform 36 can be lifted out of the depression and extended to a desired height by extending the adjustable shaft 42. The support platform 36 can then be unfolded into its open configuration. Objects can then be placed on the support platform 36 for convenient use.
Referring to
The support platform 54 sits in a depression 30 that mimics the shape of the support platform 54. Since the support platform 54 is large and is mounted to a larger bag construct 12, the support platform 54 is supported by two adjustable telescoping shafts 60. This provides the larger support platform 54 with increased support strength and stability. In this manner, the support platform 54 can be made strong enough to act as a seat as well as a support platform for secondary objects.
It will be understood that the embodiments of the present invention that are illustrated and described are merely exemplary and that a person skilled in the art can make many variations to those embodiments. For instance, the size, shape and model of the bag construct can be changed to accommodate different needs. Likewise, the support platform can have a wide variety of shapes. All such embodiments are intended to be included within the scope of the present invention as defined by the claims.
This application claims the benefit of U.S. Provisional Patent Application No. 62/899,709, filed Sep. 12, 2019.
