DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 1-8 , an external strap buckling assembly embodied in the present invention comprises an outer housing 20 , an inner housing 60 , an urging block 30 , an elastic body 40 , a locating plate 50 , and a male retainer 10 by which a strap 70 is detachably fastened to the exterior of a luggage 80 for the purpose of holding an attachment to the luggage 80 .

The outer housing 20 is fastened with the external side of a shell 81 of the luggage 80 and is provided in the interior with a cell 21 . The outer housing 20 is further provided in a top 24 with a through slot 25 in communication with the cell 21 , and in a bottom 28 with an opening 23 and a plurality of threaded holes 26 engageable with screws 64 .

The inner housing 60 is provided with an open slot 61 and a top 62 corresponding in size and shape to the top 24 of the outer housing 20 . The inner housing 60 is further provided in a bottom 65 with a plurality of through holes 63 corresponding in location to the threaded holes 26 of the outer housing 20 .

The locating plate 50 is provided with a plurality of through holes 51 corresponding in location to the through holes 63 of the inner housing 60 and the threaded holes 26 of the outer housing 20 . The locating plate 50 is disposed in the open slot 61 of the inner housing 60 .

The urging block 30 is provided in the upper side with a protrusion 31 corresponding to the through slot 25 of the outer housing 20 . The urging block 30 is movably disposed in the opening 23 of the bottom 28 of the outer housing 20 .

The elastic body 40 is disposed between the urging block 30 and the locating plate 50 such that one end of the elastic body 40 urges the underside of the urging block 30 , and such that the other end of the elastic body 40 is located on the locating plate 50 .

The outer housing 20 and the inner housing 60 are fastened together by a plurality of screws 64 , which are engaged with the threaded holes 26 of the outer housing 20 via the through holes 63 of the inner housing 60 and the through holes 51 of the locating plate 50 . The outer housing 20 is fastened to the external side of the shell 81 of the luggage 80 , while the inner housing 60 is fastened to the internal side of the shell 81 of the luggage 80 , as shown in FIGS. 2-6 .

The male retainer 10 is fastened at one end 11 with the strap 70 and is provided at other end with an engagement portion 12 of an L-shaped construction. The engagement portion 12 is provided with a projection 13 extending from the engagement portion 12 . In operation, the engagement portion 12 and the projection 13 are put into the cell 21 of the outer housing 20 via the through slot 25 of the outer housing 20 such that the engagement portion 12 and the projection 13 press against the protrusion 31 of the urging block 30 , thereby resulting in compression of the elastic body 40 , as shown in FIGS. 2 and 3 . As the engagement portion 12 is relieved of the pressure exerting thereon, the engagement portion 12 is caused by the spring force of the elastic body 40 to moved upward, thereby causing one arm 121 of the L-shaped engagement portion 12 and the projection 13 to be stopped by two arresting portions 251 of the through slot 25 . The arresting portions 251 are in fact the walls which are contiguous to the inner end edge of the through slot 25 . It must be noted here that the projection 13 is aligned with the one arm 121 of the L-shaped engagement portion 12 . The engagement portion 12 is held securely in place in the cell 21 such that the arm 121 and the projection 13 are held securely between the arresting portions 251 and the protrusion 31 of the urging block 30 .

The male retainer 10 can be disengaged with the outer housing 20 by exerting pressure on the engagement portion 12 so as to cause the urging block 30 to move downward to press against the elastic body 40 , thereby enabling the projection 13 to be first moved out of the cell 21 via the through slot 25 , as shown in FIG. 5 . The arm 121 of the engagement portion 12 is then pulled out of the cell 21 via the through slot 25 . In the meantime, the urging block 30 is forced by the spring force of the elastic body 40 to move back up such that the protrusion 31 of the urging block 30 is fitted into the through slot 25 of the outer housing 20 , as shown in FIG. 6 . The through slot 25 is thus sealed off by the protrusion 31 of the urging block 30 .

The outer housing 20 is further provided in the bottom 28 with a plurality of retaining cavities 27 . The locating plate 50 is provided in the upper side with a plurality of retaining pillars 52 corresponding in location to the retaining cavities 27 of the outer housing 20 . The outer housing 20 is further located securely by the locating plate 50 such that the retaining pillars 52 of the locating plate 50 are retained in the retaining cavities 27 of the outer housing 20 .

The elastic body 40 may be a spring. Accordingly, the locating plate 50 is provided in the upper side with a locating projection 53 for locating the spring 40 .

As shown in FIG. 8 , the present invention is free of the deficiencies of the prior art buckling device 90 as shown in FIG. 9 . The top 24 of the outer housing 20 of the present invention is almost level with the external side of the shell 81 of the luggage 80 . In the meantime, the through slot 25 of the outer housing 20 of the present invention is sealed off by the protrusion 31 of the urging block 30 . The advantages of the present invention over the prior art device are therefore readily apparent.

The embodiment of the present invention described above is to be regarded in all respects as being illustrative and nonrestrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scope of the following claims.
