The present invention is generally related to luggage and containers, and more particularly related to expandable, wheeled luggage and containers.
The use of a collapsible bag, container or luggage item is often preferred inasmuch as such items are more easily stored because they can be folded or made compact when not in use. Additionally, such items are typically lighter in weight. Also, because soft-sided luggage items, containers or bags have flexible sides, they may be used to hold and transport uniquely shaped items that could not be easily placed and stored in a hard-sided luggage item or container. Further, flexible bags are often more economical to manufacture and easier to move or transport.
Examples of various containers or luggage items are shown, in the following United States patents: Shyr et al., U.S. Pat. No. 5,307,908; Tan, U.S. Pat. No. 6,401,890; Godshaw et al., U.S. Pat. No. 6,550,592; Kotkins, Jr., U.S. Pat. No. 5,209,328; Knight, U.S. Pat. No. 4,160,496; Cohen, U.S. Pat. No. 4,756,394.
Although such bag, container or luggage items have achieved popularity and commercial success, there has been a continuing need for improvement.
A shortcoming of bags such as those shown in the above referenced patents is that many times the wheels are left exposed when the bag is disposed in its folded state. This is undesirable because the wheels may be dirty from having been used on various surfaces such as sidewalks, streets or other unclean surfaces. Therefore it is desirable to design a collapsible bag wherein the wheels are not exposed when the bag is in a collapsed state. As shown in U.S. Pat. No. 4,756,394, the bag shown and described therein does not dispose the wheels in a folded state but rather merely contemplates the detachment and removal of the exposed wheels.
An additional shortcoming of those bags shown above is that many of the bags are not collapsible upon the base member of which they extend from. For example, as shown in U.S. Pat. No. 5,307,908 and as shown in U.S. Pat. No. 6,401,890, when the bags shown therein are disposed in a folded state, the sides of the bag extend beyond the area of the base, thereby taking up more space than necessary. As shown in U.S. Pat. No. 4,160,496, the bag does not fold onto the base member but rather the bag is folded by sandwiching the bag between the folded halves of the bag's body member.
A further limitation still of the bags described above is that they cannot be completely expanded from and contracted to its base member with a single zipper. As shown in the above bag, each bag requires multiple folding and/or zippering steps to expand and contract them, thereby taking more time and effort than necessary.
Therefore it is an object of the present invention to provide a collapsible wheeled container, which when disposed in a collapsed state, provide for wheels that are not exposed.
It is a further object of the present invention to provide a collapsible wheeled container, wherein when the container is disposed in a collapsed state, the collapsed bag does not extend beyond the area of the base member from which the bag extends from in an un-collapsed state.
It is a further object of the present invention to provide a collapsible wheeled container, wherein the collapsed container is expanded from its base member to an expanded state, or vice versa, though a single zipper mechanism.
These and other objects, advantages, and features of the invention will become apparent to those persons skilled in the art upon reading the details of the methods and systems of the present invention which are more fully described below.
The present invention provides for an improved collapsible container that includes a base, which has a portion moveable between a collapsed and expanded position, at least one wheel associated with the one side of the base and a body associated with the base, where the body is moveable between a collapsed and an expanded position. The container uses a single zipper or other fastening mechanism as a means to retain the moveable portions of the container in its collapsed and expanded positions. The container further includes support members configured to shape and retain the collapsible portion of the body member. The support members may be in the form of removable members or alternatively, the support members may be integrated within or upon the body member.
In accordance with the present invention there is provided: a collapsible container, said collapsible container comprising a base member, said base member having a portion movable between a first and second position; at least one wheel member associated with a first side of said base member; a body member associated with said base member, said body member movable between a collapsed position and an expanded position; at least one support member associated with said body member, said support member being either removable or resilient.
In accordance with the present invention there is provided a non-rigid collapsible container, the collapsible container comprising: a semi-rigid base member, the base member having a portion movable between a first and second position; at least one wheel member associated with a first side of the base member; a body member associated with the base member, the body member movable between a collapsed position and an expanded position; and a support member, the support member associated with the body member, wherein the support member is configured to support at least a portion of the body member when the body member is disposed in an expanded position.
In accordance with the present invention there is provided a collapsible container, including a semi-rigid base member, said base member having a portion movable between a first and second position, wherein the base member is at least partially covered with a material; at least two wheel members fixedly attached to a first side of the base member; a body member associated with the base member, said body member movable between a collapsed position and an expanded position; and support member, the support member associated with the body member, wherein the support member is configured to support at least a portion of the body member when the body member is disposed in an expanded position.
