ABSTRACT:
RELATED APPLICATION
The present invention claims the priority of Taiwanese Patent Application No. 088205734, filed on Apr. 14, 1999, and issued on Jan. 21, 2000, as Taiwanese Patent No. 380388, which is herein incorporated by reference.
1. Field of the Invention
The present invention relates to a traveling luggage, especially, a multi-purpose traveling luggage which helps a traveler alleviate troubles due to having multiple luggages. The present invention is an improvement of U.S. Pat. No. 6,016,893, issued on Jan. 25, 2000, which is herein incorporated by reference.
2. Background of the Invention
It is usually very inconvenient and burdensome for a traveler to carry numerous luggages. To minimize the inconvenience, various innovations have been developed and sold in the market. Examples of such innovations include using a foldable lightweight stroller to assist in transporting heavy luggages, designing luggages with an attached pulling bar and rolling wheels for easy movement, etc. However, these designs pose considerable burden to a traveler when the luggages are not in use, because they are only useful for pulling themselves and do not have the capability of lessening the burden of carrying other luggages.
To alleviate the aforementioned inconvenience and burden of a traveler, U.S. Pat. No. 6,016,893 provides a multi-purpose traveling luggage, which is not only simply structured and easily handled, but also versatile enough to be used as a sitting stool, a baby stroller, or a cart for carrying multiple pieces of baggage.
While the multi-purpose traveling luggage of U.S. Pat. No. 6,016,893 is generally satisfactory in achieving its intended goals, it has the following shortcomings:
1. When the multi-purpose luggage is used as a cart for carrying other luggage(s), instead of as a sitting stool or baby stroller, the drive rod members are not connected to the luggage body, thus, there is no place for putting other luggages onto the multi-purpose luggage-converted carrying cart;
2. For the aforementioned reasons, the drive rod members of the multi-purpose luggage tend to close on themselves, which make them more difficult to handle when the multi-purpose luggage functions as a cart;
3. In order to carry other luggage(s), the swing case of the multi-purpose luggage has to be elevated to form the support surface, which requires multiple steps of unlocking, opening the frame, elevating and rotating, and locking the frame; it is inconvenient for a traveler, especially when encountering uneven road conditions or stairs, to close the frame and carry the luggage(s) by hand.
SUMMARY OF THE INVENTION
It is then an objective of the present invention to provide a multi-purpose traveling luggage which is lightweight, sturdy, convenient, and can be used for carrying other luggage(s), thus, lessening the burden and exhaustion resulted from carrying several luggages for travelers.
Particularly, it is an objective of the present invention to provide a multi-purpose traveling luggage, which can be pulled or pushed, used for carrying other luggages, and maneuvered at any directions.
Further, it is another objective of the present invention to provide a multi-purpose traveling luggage which can instantly be converted from a normal luggage into a pulling luggage or a luggage that carries other luggage(s). This multi-purpose traveling luggage is fast and convenient for a traveler.
The present invention is directed to a multi-purpose traveling luggage which comprises a case body having a backboard at the back, an associated cover connected to the front portion of the case body. When the multi-purpose luggage is in the erect position, two caster wheels are seen at the outer comers of the bottom side of the associated cover. There is a pair of leg supports attached to the midportion of the backboard. Each of the lower ends of the leg supports is connected to a leg wheel. Each of the upper ends of the leg supports is fixedly connected to the outer edge of the backboard.
Additionally, there is a pair of drive rod members. The lower portions of the drive rod members are fixedly connected to the lower portions of the backboard at the outer edges. The upper portions of the drive rod members are connected to each other by a connecting rod member, which slidably engages in the leg supports to form a scissor-like support frame. The drive rod members telescopically receive a pair of extension rods, which are united by a handle bar to facilitate the pushing or pulling of the scissor-like support frame.
The two distal ends of the connecting rod member are encased in two casing tubes which can rotate around the connecting rod member. The two casing tubes are connected by a connecting board, which size is within the space limit between the two drive rod members. The connecting board can be flipped counterclockwise from its folding position at the connecting rod member to the top of the case body which then can securely connect the upper portion of the drive rod members to the top of the case body to form a support surface. The support surface formed by the connecting board on top of the case body can be used to carry other luggages.
In addition, there is a hook lock located in the middle of the upper portion of the back side of the backboard which can lock the drive rod members in a closed position or release the drive rod members from such a position. There are also two L-shaped hooks located at the two shoulders of the upper portion of the backboard. These L-shaped hooks are used to lock the handle bar of the extension rod members to prevent the supporting frame from being accidentally released.
