[47] Fig. 9 is a main part perspective view illustrating a balancing means provided in a cart type bag according to a sixth embodiment of the present invention.
[48] As shown in Fig. 9, the balancing means provided in the cart type bag according to the sixth embodiment of the present invention comprises a fixing tube 467 that is provided at the bottom side of the rest 310 in correspondence to at least one through hole 466 formed at a side of the rest 200, a balancing bar 468 that is provided in correspondence to the through hole 466 and is inserted in the fixing tube 467 through the through hole 466, and a fixing rack comprising a hooking jaw 468a that projects from a side of the balancing bar 468 and fixes the balancing bar 468 inserted in the fixing tube 467 through the through hole 466, with a rear side and both sides of the hooking jaw 468a cut. When the balancing bar 468 is inserted in the fixing tuber 467 through the through hole 466, the hooking jaw 468a is hooked and fixed on the rest 200.
[49] On the other hand, as shown in Fig. 4, the cart type bag further comprises a retractable handle 500 and a pair of fixing holes 311 that is formed on the mount 310 constituting the bag movement member 300 and in which both ends of the retractable handle 500 are inserted and fixed. The length of the retractable handle 500 can be adjusted, thereby allowing a user to carry the cart type bag conveniently. The adjustment of length of the retractable handle 500 is known in the art, and therefore, explanation thereof will be omitted for the sake of avoiding complexity of description.
[50] In addition to the retractable handle 500, a fixed handle may be attached on the top side of the cart type bag.
[51] As described above, the cart type bag of the present invention may be selectively applied to a trunk type bag for crumple prevention of stored items and convenient transport and a knapsack for convenient storage.
[52] First, if the cart type bag is used as the trunk type bag, the pair of base plates 110 and 120 constituting the bottom side volume adjustment member 100 fixed on the inner bottom side of the cart type bag is balanced and fixed by the balancing means.
[53] At this time, if the bottom side volume adjustment member 100 comprises the pair of base plates 110 and 120 integrally formed and having the fold groove 130 formed therein, the pair of base plates 110 and 120 becomes flat by unfolding the fold groove 130. On the other hand, if the bottom side volume adjustment member 100 comprises the pair of base plates 110 and 120 separately formed, and interconnected and fixed by
the hinge (not shown), the pair of base plates 110 and 120 becomes flat by unfolding the hinge.
[54] Here, as in the first embodiment, when the balancing means that balances the bottom side volume adjustment member 100 comprises the through hole 411 formed in the side of the rest 200, and the fixing tube 412 and the balancing bar 413 that are provided in the bottom side of the mount 310, the bottom side volume adjustment member 100 becomes flat by inserting the balancing bar 413 into the fixing tube 412 through the through hole 411. At this time, since the hooking jaw 413a, which projects from the balancing bar 413, is hooked on the hooking hole 412a, which is formed in the edge of the outer bottom side of the fixing tube 412, the balancing bar 413 is prevented from being separated from the fixing tube 412.
[55] In addition, as in the second embodiment, when the balancing means that balances the bottom side volume adjustment member 100 comprises the rotating balancing bar
421, which is attached on the bottom side of the rest 200, and the insertion member
422, which is provided at the bottom side of the mount 310 and has the insertion space 422a, the bottom side volume adjustment member 100 becomes flat by rotating and forcedly inserting the rotating balancing bar 421 into the insertion space 422a of the insertion member 422.
[56] In addition, as in the third embodiment, when the balancing means that balances the bottom side volume adjustment member 100 comprises the guiding part 432 having the one rail groove 431 formed in the inner side of the rest 200 and the other rail grove 432a formed in the bottom side of the mount 310, and the balancing plate 433 slid and inserted between the one rail groove 431 and the other rail groove 432a, the bottom side volume adjustment member 100 becomes flat by sliding and inserting the balancing plate 433 between the one rail groove 431 and the other rail groove 432a.
[57] On the other hand, the balancing means of the fourth embodiment has the same operation as the third embodiment except that the balancing plate 433 of the third embodiment is slid from the side while the balancing plate 436 is slid from the front.
[58] In addition, as in the fifth embodiment, when the balancing means that balances the bottom side volume adjustment member 100 comprises the fixing tube 461 provided at the bottom side of the rest 310 in correspondence to the through hole 460 formed at the side of the rest 200, and the balancing bar 462, the bottom side volume adjustment member 100 becomes flat by inserting the balancing plate 462 into the fixing tube 461 through the through hole 460.
[59] In this case, since the hooking jaw 465a projecting from the side of the balancing bar 462 is hooked on the rest 200 and the edge of the blocking plate 464 attached to the outer side of the balancing bar 462 is stopped by the outer side of the rest 200 at which the through hole 460 is formed, the balancing bar 462 is prevented from being
separated from the fixing tube 461.
[60] On the other hand, the balancing means of the sixth embodiment has the same operation as the fifth embodiment, and therefore, description thereof will be omitted.
[61] As described, when the cart type bag in which items (for example, clothes) are stored is carried, with the bottom side volume adjustment member 100 balanced, the stored items can be prevented from being crumpled since the cart type bag has a standardized space like the trunk type bag.
[62] In addition, in the cart type bag, the retractable handle 500 is fixed on the top side of the bag movement member 300 and the wheels 320 are attached on the bottom side of the bag movement member 300. This allows a user to carry the cart type bag conveniently.
[63] In addition, after detaching the retractable handle 500 from the cart type bag, a user can carry the cart type bag using the fixed handle attached on the top side of the cart type bag.
[64] On the other hand, if the cart type bag is used as a knapsack which can be shrunk and restored, the balancing means that balances the bottom side volume adjustment member 100 is removed from the cart type bag.
[65] In the case of the balancing means of the first embodiment in which the bottom side volume adjustment member 100 becomes flat by inserting the balancing bar 413 into the fixing tube 412 through the through hole 411, the balancing bar 413 is removed from the cart type bag. At this time, since the balancing bar 413 inserted in the fixing tube 412 is under the condition where the hooking jaw 413a of the balancing bar 413 is inserted and fixed in the hooking hole 412a, the balancing bar 413 must be removed with the hooking jaw 413a pressed down.
[66] In the case of the balancing means of the second embodiment in which the bottom side volume adjustment member 100 becomes flat by forcedly inserting the rotating balancing bar 421 into the insertion space 422a of the insertion member 422, the balancing of the bottom side volume adjustment member 100 is released by rotating the forcedly inserted rotating balancing member 100.
[67] In the case of the balancing means of the second embodiment in which the bottom side volume adjustment member 100 becomes flat by sliding and inserting the balancing plate 433 between the one rail groove 431 and the other rail groove 432a, the balancing of the bottom side volume adjustment member 100 is released by removing the slid balancing plate 433.
[68] In addition, the fixation of the balancing means according to other remaining embodiments is released or removed in a reverse order of the fixation procedure or in the same way as the above-described first to third embodiments, and therefore, description of which will be omitted.
[69] As described above, when the cart type bag of the present invention is stored in a moving body (airplane, vehicle, train, ship, etc) in use under the condition where the balancing of the bottom side volume adjustment member 100 is removed, the volume of the cart type bag can be adjusted depending on the extent of stored items, which leads to good space availability.
[70] Such good space availability causes increase of the number of cart type bags loaded in a container for export, which results in saving of the expenses of carriage.
[71]
