Title: Luggage system for simultaneous transporting of attached luggage pieces

Description:
FIELD OF THE INVENTION 
     This invention relates generally to transporting of luggage pieces and is particularly related to a luggage system for simultaneous transporting of attached luggage pieces which are secured to each other during their transportation. 
     BACKGROUND OF THE INVENTION 
     Travelers often need to carry more than one piece of luggage during their travel and it is a matter of common experience that carrying large and heavy suitcases can be extremely difficult and strenuous. The development of wheeled luggage has, to an extent, eased the transportation of heavy luggage and systems have been developed for piggybacking of luggage to facilitate the carrying of more than one piece of luggage. Several prior art patents have disclosed systems for piggybacking or side attachments of suitcases in order to facilitate the carrying of more than one piece of luggage. See, e.g., U.S. Pat. No. 4,759,431 issued to William L. King and Daniel G. Elles on Jul. 26, 1988; U.S. Pat. No. 5,593,609 issued to William L. King on Jan. 14, 1997; and U.S. Pat. No. 5,762,169 issued to Laurence J. Deliman et al. on Jun. 9, 1998. 
     Piggybacking suitcases frequently cause one or the other suitcase to be displaced even when they are strapped. Side-by-side carrying of two or more luggage can also result in displacement or separation between the luggages. Both of these systems are inconvenient and often require reassembling and securely strapping the luggages. 
     Accordingly, it is an object of this invention to provide a luggage system which assures securing the luggages so as to prevent their displacement or separation during their transportation. 
     It is also an object of this invention to provide a luggage system which facilitates simultaneous transportation of more than one piece of luggage regardless of size and with minimal or no possibility of displacement or separation during their transportation. 
     The foregoing and other advantageous features of this invention will become evident from the following detailed description of the invention and the accompanying drawings. 
     SUMMARY OF THE INVENTION 
     In accordance with this invention, a luggage system is provided consisting of two suitcases which can be secured to one another and can be conveniently transported without displacement of the luggage. This system contemplates using two side-by-side suitcases wherein a side of one suitcase faces an opposed side of the other suitcase. A male connector is hingedly connected to a side of one suitcase and a female connector is hingedly connected to the opposed side of the other suitcase. The male connector has a laterally extending male member and the female connector has a laterally extending channel defining the female member, on the same horizontal plane as the male member. The male member is adapted to be engaged, such as frictionally into the female member and is secured therein. A vertically disposed pin vertically extending through the female member prevents displacement of the male member and assures interlocking engagement of the male connector into the female connector.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the drawings and first to the embodiment illustrated by  FIGS. 1-5 , there is shown in  FIG. 1  two wheeled suitcases  11  and  13  each having roller wheels  15  and  17  and provided with pull handles  19  and  21 . Although one suitcase is shown smaller than the other, the two suitcases may be equal or different in size and each handle may be of the collapsible type. Each of the face sides  11 A and  13 A of the two suitcases  11  and  13  is provided with a connector such as the male connector  23  and the female connector  25  which face opposite each other and are adapted to inter-engage as hereinafter explained. 
       FIG. 4  shows the male connector  23  hingedly connected to the side wall  11 A as at  25 , having a laterally extending male member  27 , and a female connector  29  hingedly connected to the side wall  13 A as at  31 , having a laterally extending channel  33  which defines the female portion of the female connector  29 . The male member  27  and the channel  33  are sized so that in order to attach the suitcases  11  and  13 , the male member  27  is engaged into the channel  33  and is secured therein against displacement by the pin  35  which serves to prevent reverse displacement of the male member. See  FIG. 5 . The aforementioned arrangement and its description indicate the means of attachment of two suitcases which can be transported with ease by pulling the handle  19  without displacement of the luggage. 
     Alternatively, the male member  27  may be externally threaded and the channel  33  may be internally threaded for threaded engagement of the male member  27  into the female member (channel  33 ). 
       FIGS. 6 and 7  illustrate another embodiment of the invention in which the side face  11 A of suitcase  11  and side face  13 A of suitcase  13  is each provided with a magnet such as the magnets  115  and  117  so that when the two suitcases are attached side-by-side, the magnetic surface of each magnet are magnetically attached to each other thus securing the two suitcases for transporting by pulling the handle  19 . 
     From the foregoing description other changes and modifications are suggested which are obvious to one skilled in the art. For example, the male and female members may be threaded to facilitate threaded engagement of the male member with the female member. Also, more than two suitcases may be attached by providing opposed, i.e., facing sides of each suitcase with a connector as herein described. Also, the male connector and female connector may be made of metallic or a suitable plastic material.
