When thebalancing bar 468 is inserted in thefixing tuber 467 through thethrough hole 466, thehooking jaw 468 a is hooked and fixed on therest 200. - On the other hand, as shown in
FIG. 4 , the cart type bag further comprises aretractable handle 500 and a pair offixing holes 311 that is formed on themount 310 constituting thebag movement member 300 and in which both ends of theretractable handle 500 are inserted and fixed. The length of theretractable handle 500 can be adjusted, thereby allowing a user to carry the cart type bag conveniently. The adjustment of length of theretractable handle 500 is known in the art, and therefore, explanation thereof will be omitted for the sake of avoiding complexity of description. - In addition to the
retractable handle 500, a fixed handle may be attached on the top side of the cart type bag. - 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.
- First, if the cart type bag is used as the trunk type bag, the pair of
base plates volume adjustment member 100 fixed on the inner bottom side of the cart type bag is balanced and fixed by the balancing means. - At this time, if the bottom side
volume adjustment member 100 comprises the pair ofbase plates fold groove 130 formed therein, the pair ofbase plates fold groove 130. On the other hand, if the bottom sidevolume adjustment member 100 comprises the pair ofbase plates base plates - Here, as in the first embodiment, when the balancing means that balances the bottom side
volume adjustment member 100 comprises the throughhole 411 formed in the side of therest 200, and the fixingtube 412 and the balancingbar 413 that are provided in the bottom side of themount 310, the bottom sidevolume adjustment member 100 becomes flat by inserting the balancingbar 413 into the fixingtube 412 through the throughhole 411. At this time, since the hookingjaw 413 a, which projects from the balancingbar 413, is hooked on the hookinghole 412 a, which is formed in the edge of the outer bottom side of the fixingtube 412, the balancingbar 413 is prevented from being separated from the fixingtube 412. - In addition, as in the second embodiment, when the balancing means that balances the bottom side
volume adjustment member 100 comprises therotating balancing bar 421, which is attached on the bottom side of therest 200, and theinsertion member 422, which is provided at the bottom side of themount 310 and has theinsertion space 422 a, the bottom sidevolume adjustment member 100 becomes flat by rotating and forcedly inserting therotating balancing bar 421 into theinsertion space 422 a of theinsertion member 422. - In addition, as in the third embodiment, when the balancing means that balances the bottom side
volume adjustment member 100 comprises the guidingpart 432 having the onerail groove 431 formed in the inner side of therest 200 and theother rail grove 432 a formed in the bottom side of themount 310, and thebalancing plate 433 slid and inserted between the onerail groove 431 and theother rail groove 432 a, the bottom sidevolume adjustment member 100 becomes flat by sliding and inserting thebalancing plate 433 between the onerail groove 431 and theother rail groove 432 a. - 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 thebalancing plate 436 is slid from the front. - In addition, as in the fifth embodiment, when the balancing means that balances the bottom side
volume adjustment member 100 comprises the fixingtube 461 provided at the bottom side of therest 310 in correspondence to the throughhole 460 formed at the side of therest 200, and the balancingbar 462, the bottom sidevolume adjustment member 100 becomes flat by inserting thebalancing plate 462 into the fixingtube 461 through the throughhole 460. - In this case, since the hooking
jaw 465 a projecting from the side of the balancingbar 462 is hooked on therest 200 and the edge of the blockingplate 464 attached to the outer side of the balancingbar 462 is stopped by the outer side of therest 200 at which the throughhole 460 is formed, the balancingbar 462 is prevented from being separated from the fixingtube 461. - 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.
- 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. - In addition, in the cart type bag, the
retractable handle 500 is fixed on the top side of thebag movement member 300 and thewheels 320 are attached on the bottom side of thebag movement member 300. This allows a user to carry the cart type bag conveniently. - 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. - 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. - 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 balancingbar 413 into the fixingtube 412 through the throughhole 411, the balancingbar 413 is removed from the cart type bag. At this time, since the balancingbar 413 inserted in the fixingtube 412 is under the condition where the hookingjaw 413 a of the balancingbar 413 is inserted and fixed in the hookinghole 412 a, the balancingbar 413 must be removed with the hookingjaw 413 a pressed down. - 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 therotating balancing bar 421 into theinsertion space 422 a of theinsertion member 422, the balancing of the bottom sidevolume adjustment member 100 is released by rotating the forcedly inserted rotating balancingmember 100. - 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 thebalancing plate 433 between the onerail groove 431 and theother rail groove 432 a, the balancing of the bottom sidevolume adjustment member 100 is released by removing the slid balancingplate 433. - 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.
- 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. - 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.
- As apparent from the above description, the present invention provides a cart type bag whose volume can be minimized when the cart type bag is carried or stored, while keeping convenience of the cart type bag.
