Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a combination baggage trunk comprising a set of covers and open or box frames which are sized in proper or integer ratio relationship and can thus be joined together to a baggage assembly containing a number of container spaces or to a combination of a shoulder bag, an attache case, a suitcase, etc. 
     A known combination trunk is comprised mainly of covers and open frames to which the covers are detachably mounted for closing two opening sides, or box frames of which opening side is closed with the cover, which all are arranged in size for assembly in desired combinations. 
     The known combination trunk can have a large container space with two or more of the frames being coupled to each other in a depthwise direction. However, such an arrangement, fails to provide a plurality of container spaces and will thus be limited in use. 
     Also, coupling of the frames involves an increase in the overall width, but not length nor height. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention, in view of the foregoing disadvantages of the prior art, to provide a combination trunk in which the covers can be coupled to each other in a desired combination for producing a plurality of container spaces which are different in size. 
     It is another object of the present invention to provide a combination trunk comprising a plurality of covers and open or box frames which are sized in integer ratio relationship and can be assembled to a desired form, e.g. a shoulder bag, an attache case, or a suit case and to a combination of e.g. a suit case accompanied with an attache case and a shoulder bag.

For example, one large-sized case 4 and one medium-sized can be assembled to an assembly unit 1A as illustrated in FIGS. 23 and 24, a large-sized case 4 and two small-sized cases 2,2 can be assembled to an assembly unit 1B as illustrated in FIGS. 25 and 26, a medium-sized case 3 and two small-sized cases 2,2 can be assembled to an assembly unit 1C as illustrated in FIGS. 27 and 28, two large-sized cases 4,4, four medium-sized cases 3,3,3,3 and four small-sized cases 2,2,2,2 can be assembled together to an assembly unit 1D, and so on. 
     Also, the two small-sized frames 8,8 can be coupled to each other by the zip-fastener 12 thus producing a smallsized case assembly unit 2A which is about two times greater in container size than the small-sized case 2, as shown in FIGS. 31 and 32. 
     Equally, two or more of the frames 29 and 36 of their respective medium-sized and large-sized cases 3 and 4 can be coupled to one another with the zip-fasteners 33 and 40 respectively. 
     The other embodiments of the present invention will now be described referring to FIGS. 33 to 43. Like components identical to those of the first embodiment are denoted by like numerals throughout the drawings and will no more be explained. 
     A second embodiment of the present invention shown in FIGS. 33 to 35 is distinguished from the first embodiment by the fact that each of two small-sized component cases 2E,2E comprises a small-sized box frame 55 closed at one side and a small-sized cover 9, a medium-sized component case 3A comprises a medium-sized box frame 56 closed at one side and a medium-sized cover 30, and a large-sized component case 4A comprises a large-sized box frame 57 closed at one side and a large-sized cover 37, which all constitute a combination trunk 1E. The combination trunk 1E comprising the two small-sized cases 2E,2E, the medium-sized case 3A, and the large-sized case 4A will offer the same advantages as the first embodiment of the present invention. 
     Another form of a small-sized component case 2B may be arranged using the small-sized box frame 55, the small-sized frame structure 8, and the small-sized cover 9, as shown in FIGS. 36 and 37. 
     Also, the medium-sized case 3A may be consisted mainly of a medium-sized box frame 56, a medium-sized frame structure 29, and a medium-sized cover 30. The large-sized case 4A may be consisted mainly of a large-sized box frame 57, a large-sized frame structure 36, and a large-sized cover 37. 
     A third embodiment of the present invention shown in FIGS. 38 to 40 is distinguished from the first embodiment by the fact that a small-sized component case 2C has a small-sized frame 8A which comprises an outer frame coat 11, six pairs of joiner blocks 14, and a bottom plate 58 without the use of a small-sized frame structure. A combination trunk 1F containing the two small-sized cases 2C,2C will also offer the same advantages as of the first embodiment of the present invention. 
     The cover 9 of the small-sized case 2C may have a handle grip 7A mounted at both ends to the two joiners 22,22 as shown in FIG. 39. 
     The frame 29 of the medium-sized case 3 may be formed without the use of the frame structure 31. Also, the frame 36 of the large-sized case 4 may be formed with no use of the frame structure 38. 
     A fourth embodiment of the present invention shown in FIGS. 41 to 43 is distinguished from the first embodiment by the fact that the small-sized component case 2 is replaced with an arrangement 2D which comprises a small-sized frame 8B having an outer frame coat 11A provided at its upper center with a zip-fastener 59 for opening and closing and six pairs of the joiner blocks 14 mounted to the outer frame coat 11A, two closing plates 60,60 covering the two sides of the small-sized frame 8B, and six pairs of the fasteners 22 mounted to the two closing plates 60,60. A combination trunk 1G containing the two small-sized cases 2D,2D will offer the same advantages as the first embodiment of the present invention. 
     Although a zip-fastener is used for joining between the frame and the cover throughout the foregoing embodiments of the present invention, it is not intended to be limitative and another opening and closing means such as a hinge with a lock mechanism will be employed with equal success. 
     While the present invention is herein described preferably with respect to a combination of small-sized component cases, a medium-sized component case, and a large-sized component case, any modification may be made having, for example, two smaller-sized component cases coupled to the cover of the small-sized component case or two large-sized component cases coupled side by side. 
     As set forth above, the present invention will provide the following advantages: 
     (1) The components cases can be coupled to each other in the depthwise, widthwise, and vertical directions, thus determining a given size appropriate to the purpose of use. 
     (2) While a plurality of the component cases are coupled together, its corresponding number of container spaces can be acquired for best efficient use. 
     (3) A larger container space can be provided by coupling two or more of the open frames of the component cases. 
     (4) The component cases of different sizes which are arranged in a ratio of about 2:1 can be coupled for having a desired size and shape for ease of use.
