[0027] It should be noted herein that for clarity of description, spatially relative terms such as top, bottom, upper, lower, on, above, over, downwardly, upwardly and the like may be used throughout the disclosure while making reference to the features as illustrated in the drawings. The features may be oriented differently (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein may be interpreted accordingly.

[0028] Referring to FIGS. 1 to 3, a multi-purpose bag according to an embodiment of the disclosure includes a bag unit 1 and a strap unit 2.

[0029] The bag unit 1 serves as a flexible bag body that has a bag bottom 11, a front bag segment 12, a rear bag segment 13, two connecting ring members 14, and two limiting ring members 15.

[0030] The front bag segment 12 is located at a front portion of the bag unit 1 and is connected to the bag bottom 11.

[0031] The rear bag segment 13 is located at a rear portion of the bag unit 1, is connected to the bag bottom 11, and is spaced apart from the front bag segment 12 in a front-rear direction (X). The rear bag segment 13 and the front bag segment 12 cooperatively define a bag opening 10 that is disposed above the bag bottom 11 in a top-bottom direction (Z) perpendicular to the front-rear direction (X).

[0032] Each of the connecting members 14 is connected the rear bag segment 13, is distal from the bag opening 10, and is disposed adjacent to the bag bottom 11. The connecting members 14 are spaced apart from each other in a left-right direction (Y) perpendicular to the front-rear direction (X) and the top-bottom direction (Z).

[0033] In this embodiment, the bag unit 1 further has two limiting passages 150 that are formed on the rear bag segment 13 and that are distal from the bag bottom 11. The two limiting passages 150 are spaced apart from each other in the left-right direction (Y).

[0034] The two limiting ring members 15 are connected to the rear bag segment 13, are disposed adjacent to the bag opening 10, and are distal from the bag bottom 11. Each of the limiting ring members 15 is aligned with a respective one of the connecting members 14 in the top-bottom direction (Z). Each of the limiting ring members 15 defines a respective one of the limiting passages 150. The limiting passages 150 are spaced apart from each other in the left-right direction (Y).

[0035] The strap unit 2 includes two straps 21 that are crossed over each other. Each of the straps 21 extends movably through a respective one of the limiting passages 150. Each of the straps 21 has a front connection end 211, a rear connection end 212, and an adjustment strap portion 213. The front connection end 211 is connected to the front bag segment 12, is disposed adjacent to the bag opening 10, and is distal from the bag bottom 11. The rear connection end 212 is connected to the rear portion of the bag unit 1 and is disposed adjacent to the bag bottom 11. The adjustment strap portion 213 is disposed between the front connection end 211 and the rear connection end 212, and is measured from the rear connection end 212 to the respective one of the limiting passages 150. In this embodiment, each of the connecting members 14 interconnects the rear connection end 212 of a respective one of the straps 21 and the rear bag segment 13. The front connection ends 211 of the straps 21 are spaced apart from each other in the left-right direction (Y). The rear connection ends 212 of the straps 21 are spaced apart from each other in the left-right direction (Y). The front connection ends 211 of the straps 21 are sewed to a top edge of the front bag segment 12.

[0036] The strap unit 2 further includes two strap adjusters 22 are respectively connected to the straps 21. Each of the strap adjusters 22 is slidable relative to a respective one of the straps 21 for adjusting a length of the respective one of the straps 21. Since the strap adjusters 22 are well known to those skilled in the art, further details thereof are omitted herein for the sake of brevity.

[0037] Referring to FIGS. 4 and 5 in combination with FIGS. 1 and 2, each of the straps 21 is movable to transform between a shoulder bag state (as shown in FIGS. 1 and 2) and a backpack state (as shown in FIGS. 4 and 5).

[0038] When the straps 21 are in the shoulder bag state, the adjustment strap portion 213 of each of the straps 21 has a first length (L1), and the straps 21 cooperate with the bag unit 1 to define a shoulder space 201 therebetween. In this embodiment, when the straps 21 are in the shoulder bag state, the shoulder space 201 is situated directly over the bag opening 10 in the top-bottom direction (Z), the adjustment strap portion 213 of each of the straps 21 substantially abuts against the rear bag segment 13, and the straps 21 are allowed to be lifted up.

[0039] When the straps 21 are in the backpack state, the adjustment strap portion 213 of each of the straps 21 has a second length (L2) greater than the first length (L1), and each of the straps 21 cooperates with the bag unit 1 to define a back hanging space 202 therebetween. In this embodiment, when the straps 21 are in the backpack state, the straps 21 are allowed to be pulled curvedly away from the rear bag segment 13 of the bag unit 1, and the back hanging spaces 202 are situated at a rear side of the rear bag segment 13 in the front-rear direction (X).

[0040] A user needs only to pull the straps 21 upwardly or rearwardly relative to the bag unit 1 so as to drive the straps 21 to move respectively through the limiting passages 150, thereby adjusting the adjustment strap portion 213 of each of the straps 21 to have the first length (L1) or the second length (L2) for transforming each of the straps 21 into the shoulder bag state or the backpack state.

[0041] When the straps 21 are in the shoulder bag state, the shoulder space 201 allows a hand, an arm, and a shoulder of the user to extend therethrough. As a result, the user may carry the multi-purpose bag of the disclosure in the hand, on the shoulder, or in a cross-body manner.

[0042] Referring to FIG. 6 in combination with FIG. 4, when the straps 21 are in the backpack state, the arms of the user are allowed to extend respectively through the back hanging spaces 202. As a result, the multi-purpose bag of the disclosure is carried in a backpack manner. Specifically, in the backpack state, the straps 21 are crossed over each other above the bag opening 10. Pulling the straps 21 rearwardly from the rear bag segment 13 narrows the bag opening 10 such that the bag opening 10 is closed.

[0043] Referring to FIG. 7, to open the bag opening 10, the straps 21 are pulled in the left-right direction (Y) respectively toward a right side and a left side of the bag unit 1. As long as the straps 21 are moved away from the bag opening 10 and dangle relative to the front bag segment 12 and the rear bag segment 13, the bag opening 10 is allowed to be opened without being restricted by the straps 21.

[0044] FIGS. 8 to 12 illustrate variant embodiments of the strap units 2 connected to the bag unit 1. Specifically, the front connection end 211 of each of the straps 21 is not limited to being adjacent to the bag opening 10.

[0045] As shown in FIG. 8, the front connection end 211 of each of the straps 21 is adjacent to the bag bottom 11 and is fixedly connected to a bottom edge of the front bag segment 12.

[0046] As shown in FIG. 9, in addition to the limiting ring members 15 that are connected to the rear bag segment 13 and that are distal from the bag bottom 11, the bag unit 1 further has two auxiliary ring members 15 that are connected to the front bag segment 12 and that are distal from the bag bottom 11. Each of the auxiliary ring members 15 defines an auxiliary passage 150. The limiting ring members 15 and the auxiliary ring members 15 are adjacent to the bag opening 10. The two limiting passages 150 are spaced apart from each other in the left-right direction (Y). The two auxiliary passages 150 are spaced apart from each other in the left-right direction (Y). Each of straps 21 extends through the respective one of the limiting passages 150 and a respective one of the auxiliary passages 150. The front connection ends 211 of the straps 21 are spaced apart from each other in the left-right direction (Y). The rear connection ends 212 of the straps 21 are spaced apart from each other in the left-right direction (Y). The front connection end 211 and the rear connection end 212 of each of the straps 21 are connected to the bag bottom 11. Each of the straps 21 extends around an end of each of the front bag segment 12 and the rear bag segment 13 that is opposite to the bag bottom 11. As a result, when the straps 21 are in the shoulder bag state, the shoulder space 201 (as shown in FIG. 3) is situated directly over the bag opening 10 in the top-bottom direction (Z). When the straps 21 are in the backpack state, the back hanging spaces 202 (as shown in FIG. 5) are situated at a rear side of the rear bag segment 13 in the front-rear direction (X).

[0047] As shown in FIG. 10, the bag unit 1 has a passage-defining member 15 that replaces the limiting ring members 15 (as shown in FIG. 2) and that is connected to a top portion of the rear bag segment 13. The passage-defining member 15 has a rectangular shape. The passage-defining member 15 and the rear bag segment 13 cooperatively define the limiting passages 150. Specifically, the passage-defining member 15 is sewed onto the rear bag segment 13.

[0048] As shown in FIG. 11, the bag unit 1 has two passage-defining members 15 that are spaced apart from each other in the left-right direction (Y) and that respectively replace the limiting ring members 15 (as shown in FIG. 2). Each of the passage-defining members 15 cooperates with the rear bag segment 13 to define a respective one of the limiting passages 150.

[0049] As shown in FIG. 12, the rear bag segment 13 of the bag unit 1 is cut with two pairs of slits so that the two limiting passages 150 are directly formed on the rear bag segment 13. As a result, a movement path of each of the straps 21 is limited through the respective one of the limiting passages 150.

[0050] As shown in FIG. 13, the bag unit 1 may not be the flexible bag body. In a variant embodiment as shown in FIG. 13, the bag unit 1 may be a rigid bag body. The limiting passages 150 are formed on the rear bag segment 13. Each of the limiting passages 150 is a round hole and allows a respective one of the straps 21 to move therethrough.

[0051] The multi-purpose bag of the disclosure has the following advantages.

[0052] 1. By pulling each of the straps 21 without a removal tool, each of the straps 21 is movable to transform between the shoulder bag state and the backpack state for multi-purpose uses. For manufacturers, the multi-purpose bag of the disclosure is simple in structure to make and manufacturing cost of the same may be reduced. For consumers, the multi-purpose bag of the disclosure is easy to use. Multiple purposes of usage may be satisfied by purchasing one multi-purpose bag of the disclosure. The multi-purpose bag of the disclosure is flexible in function so there is no need of purchasing multiple bags. As a result, material waste may be reduced and less space is occupied, thereby achieving the goal of being environmental friendly.

[0053] 2. Because the straps 21 are crossed over each other, when the straps 21 are in the shoulder bag state, the straps 21 cooperate with the bag unit 1 to define the shoulder space 201, and the shoulder space 201 is situated directly over the bag opening 10 in the top-bottom direction (Z). As a result, when the multi-purpose bag of the disclosure is carried in the hand, on the shoulder, or in a cross-body manner, the straps 21 are not required to be gathered together, thereby preventing the bag opening 10 from being distorted and deformed.

[0054] In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s).
