[0002] With the diversification of daily commutes, shopping, and outdoor travel, the flexibility of use for handbags, as portable storage tools, has become one of the core needs of users. Existing handbags usually have fixed handles or adjustable shoulder straps to accommodate different usage methods, such as hand-carrying and shoulder-carrying. However, common structures are mostly simple telescopic adjustments or hook switching, which still have certain shortcomings in actual use: for example, when the handbag is switched to a shoulder-carrying position, the force-bearing area of ​​the shoulder strap on the human shoulder is small, which can easily cause excessive local pressure, leading to shoulder discomfort or fatigue after prolonged use. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a handbag with an adjustable handle shape.

[0006] Furthermore, the present invention includes a receiving groove and a winding channel on one side of the handbag body; one end of the winding channel is connected to the receiving groove, and the other end extends upward through the top of one end of the handbag body; the winding device includes a winding reel rotatably disposed in the receiving groove and an elastic energy storage component disposed between the winding reel and the handbag body; the other end of the shoulder strap passes through the winding channel into the receiving groove and is connected to the winding reel; the other end of the shoulder strap is provided with a first air passage; one end of the first air passage is connected to the airbag portion;

[0007] The pump component has an air chamber that is unidirectionally connected to the outside; the pump component also has a push rod part that is movably connected to the winding reel; the push rod part has a second air passage; one end of the second air passage is unidirectionally connected to the air chamber; the other end of the second air passage is connected to the other end of the first air passage; the push rod part also has a vent valve that allows the second air passage to be connected to the outside.

[0008] Furthermore, the top of one end of the handbag body is provided with a limiting member at the opening of the storage channel; when the handbag is in the hand-carrying state, the limiting member limits the airbag part, so that the airbag part is kept contained in the storage channel.

[0009] Furthermore, the top of one end of the handbag body is provided with a groove at the opening of the storage channel; the limiting member includes a limiting block and a limiting spring; the limiting block is slidably disposed in the groove; the limiting block has a U-shaped end; the two ends of the limiting spring abut against the limiting block and the groove wall of the groove respectively; the airbag part is limited by the U-shaped end of the limiting block.

[0010] Furthermore, the present invention includes a pumping body and a piston movably disposed within the pumping body; the air chamber is formed between the pumping body and the piston; the push rod is connected to the piston; and the piston is provided with a first one-way valve in the second air passage.

[0011] Furthermore, in this invention, one end of the pump body is an open structure; the piston is provided with a second one-way valve that allows the air chamber to communicate unidirectionally with the outside.

[0012] Furthermore, the reel of the invention is provided with an air guide tube; one end of the air guide tube is connected to a first air passage; the other end of the air guide tube is connected to a second air passage via a flexible tube.

[0013] Furthermore, the outer surface of the winding reel is provided with a circular platform; the end of the push rod away from the air chamber is provided with a guide portion; a guide groove is provided in the guide portion; the circular platform is movably embedded in the guide groove; the other end of the air guide tube is fixed in the circular platform; and the flexible tube is accommodated in the guide groove.

[0015] Furthermore, in this invention, the elastic energy storage element is a coil spring or a clockwork.

[0016] The beneficial effects of this invention are as follows: By incorporating a retractor to retract the shoulder strap, the air bladder portion of the shoulder strap is housed within the side wall of the handbag body, resulting in a short strap shape that facilitates hand-carrying the bag. When switching to shoulder bag mode, the shoulder strap can be fully extended. During this extension, the retractor drives the air pump, inflating the air bladder portion of the shoulder strap and significantly increasing the contact area between the shoulder strap and the body. This effectively reduces local pressure and improves comfort when carrying the bag. Furthermore, the design of the retractor, air pump, and air bladder allows for convenient switching between hand-carrying and shoulder bag modes. The operation is simple, and it also provides load-bearing and cushioning functions during shoulder carrying, meeting the needs of multiple usage scenarios and enhancing the user experience.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the invention to this.

[0027] like Figures 1 to 8 As shown in this embodiment, an adjustable-handle handbag includes a handbag body 1 and a shoulder strap 2. A retractor 3 and an air pump 4 are provided on the side wall of one end of the handbag body 1. The air pump 4 is connected to the retractor 3 via a transmission connection. One end of the shoulder strap 2 is connected to the top of the other end of the handbag body 1. The other end of the shoulder strap 2 is connected to the retractor 3. An air bladder 21 is provided in the middle of the shoulder strap 2. The air bladder 21 is unidirectionally connected to the air pump 4. The handbag can switch between a hand-carrying state and a shoulder bag state. In the hand-carrying state, the other end of the shoulder strap 2 is wound onto the retractor 3, and the air bladder 21 is housed within the side wall of the handbag body 1. When switching the handbag from the hand-carrying state to the shoulder bag state, pulling the shoulder strap 2 causes the retractor 3 to release its winding action on the shoulder strap 2, and the air bladder 21 moves out of the handbag body 1. Simultaneously, the retractor 3 drives the air pump 4 to work, causing the air pump 4 to pump air into the air bladder 21.

[0028] Specifically, in actual use, when the adjustable handle of this embodiment needs to be carried by hand, the shoulder strap 2 is wound up by the retractor 3, so that the air bladder 21 of the shoulder strap 2 is housed within the side wall of the handbag body 1, and the air bladder 21 is not inflated, resulting in a compact overall structure. At this time, the handbag can be carried by hand. Figure 4 As shown; if it is necessary to put the handbag into the shoulder bag position, by pulling the shoulder strap 2, the retractor 3 releases its winding of the shoulder strap 2, and the air bladder 21 moves out of the handbag body 1. At the same time, during the unwinding process of the shoulder strap 2, the retractor 3 simultaneously drives the pump 4 to work, and the pump 4 inflates the air bladder 21, causing the air bladder 21 to gradually expand. The expanded air bladder 21 increases the contact area between the shoulder strap 2 and the human shoulder, significantly reducing local pressure and improving the comfort during the use of the shoulder bag. When the shoulder strap 2 is fully extended, the air bladder 21 remains inflated, so that the shoulder strap 2 remains in the extended position, as shown. Figure 5 As shown.

[0029] In this embodiment, a retractor 3 is used to retract the shoulder strap 2, allowing the air bladder 21 of the shoulder strap 2 to be housed within the side wall of the handbag body 1, making the shoulder strap 2 appear as a short rope, facilitating hand-carrying use. When switching to shoulder bag mode, the shoulder strap 2 can be completely pulled out. During the pulling process, the retractor 3 drives the air pump 4 to inflate and expand the air bladder 21 of the shoulder strap 2, significantly increasing the contact area between the shoulder strap 2 and the body, thereby effectively reducing local pressure and improving comfort when carrying the shoulder bag. This embodiment, through the design of the retractor 3, air pump 4, and air bladder 21, achieves convenient switching between hand-carrying and shoulder bag modes, is simple to operate, and also provides load-bearing and cushioning functions during shoulder carrying, meeting the needs of multiple usage scenarios and improving the user experience.

[0030] like Figure 1 , Figures 3 to 8 As shown, in some embodiments of the adjustable handle-shaped handbag, the handbag body 1 has a receiving groove 11 and a winding channel 12 on one side; one end of the winding channel 12 is connected to the receiving groove 11, and the other end extends upward through the top of one end of the handbag body 1; the winding device 3 includes a winding reel 31 rotatably disposed in the receiving groove 11 and an elastic energy storage member 32 disposed between the winding reel 31 and the handbag body 1; the other end of the shoulder strap 2 passes through the winding channel 12 into the receiving groove 11 and connects with the winding reel. 31 is connected; the other end of the shoulder strap 2 is provided with a first air passage 22; one end of the first air passage 22 is connected to the airbag part 21; the pumping component 4 is provided with an air chamber 44 that is unidirectionally connected to the outside; the pumping component 4 is also provided with a push rod part 43 that is movably connected to the take-up reel 31; the push rod part 43 is provided with a second air passage 45; one end of the second air passage 45 is unidirectionally connected to the air chamber 44; the other end of the second air passage 45 is connected to the other end of the first air passage 22; the push rod part 43 is also provided with a vent valve that allows the second air passage 45 to be connected to the outside. Preferably, the elastic energy storage component 32 is a coil spring or a spring.

[0031] Specifically, when the handbag needs to be used in a hand-carry position, the winding reel 31 rotates under the action of the elastic energy storage member 32 and winds up the shoulder strap 2, so that part of the shoulder strap 2 is coiled around the winding reel 31, and the air bladder part 21 is stored in the winding channel 12, thereby making the shoulder strap 2 appear as a short rope, such as... Figure 4As shown, this is for hand-carrying use. When switching the bag from hand-carrying to shoulder bag mode, the user can pull the shoulder strap 2, causing the winding reel 31 to rotate in the opposite direction against the elastic energy storage component 32, thus unwinding the shoulder strap 2. The shoulder strap 2 and its air bladder 21 pass through the winding channel 12 outside the bag body 1. During the rotation of the winding reel 31, the push rod 43 reciprocates, causing the air chamber 44 in the pumping component 4 to repeatedly draw in and pump air. When the volume of the air chamber 44 increases, it draws in air from the outside. When the volume of the air chamber 44 decreases, the air in the air chamber 44 is pumped into the air bladder 21 through the second air passage 45 and the first air passage 22, causing the air bladder 21 to inflate. This increases the contact area between the shoulder strap 2 and the user's shoulder, reducing the local pressure of the shoulder strap 2 on the user's shoulder during use, thereby improving the comfort of using the shoulder bag. Figure 5 As shown.

[0032] After the shoulder strap 2 is pulled out, the second air passage 45 and the air chamber 44 are unidirectionally connected, preventing the gas in the airbag 21 from flowing back. This keeps the airbag 21 in an inflated state, locking the elastic potential energy of the elastic energy storage component 32, and keeping the shoulder strap 2 extended. When it is necessary to switch the handbag from a shoulder bag state to a handbag state, the second air passage 45 is connected to the outside through the vent valve. At this time, the airbag chamber is released, and the gas in the airbag 21 is discharged to the outside through the first air passage 22 and the second air passage 45. As the airbag 21 contracts, the elastic potential energy of the elastic energy storage component 32 is released, thereby driving the winding reel 31 to wind up the shoulder strap 2. The shoulder strap 2 is partially wound onto the winding reel 31, and the airbag 21 is once again housed in the winding channel 12, thus completing the state switch. The operation is simple.

[0033] Since the airbag part 21 is connected to the outside through the first air passage 22 and the second air passage 45, and the second air passage 45 is connected to the outside, during the winding process of the rewind reel 31 winding the shoulder strap 2, the rewind reel 31 synchronously drives the push rod part 43 to reciprocate. At this time, the gas pumped out of the air chamber 44 is discharged to the outside through the second air passage 45, so that the airbag part 21 can be reliably stored in the winding channel 12.

[0034] like Figure 1 and Figure 2As shown, in some embodiments of the adjustable handle-shaped handbag, a limiting member is provided at the top of one end of the handbag body 1 at the opening of the storage channel 12. When the handbag is in the hand-carrying state, the limiting member limits the airbag portion 21, keeping the airbag portion 21 contained within the storage channel 12. Specifically, when the handbag is in the hand-carrying state, the limiting member keeps the airbag portion 21 contained within the storage channel 12, keeping the airbag portion 21 locked and preventing the airbag portion 21 from accidentally sliding out of the storage channel 12, thereby ensuring the stability of the handbag in the hand-carrying state and improving structural reliability.

[0035] like Figure 2 As shown, the adjustable handle of this embodiment of the handbag has a groove at the opening of the storage channel 12 at the top of one end of the handbag body 1. The limiting member includes a limiting block 51 and a limiting spring 52. The limiting block 51 is slidably disposed in the groove. The limiting block 51 has a U-shaped end 511. The two ends of the limiting spring 52 abut against the limiting block 51 and the groove wall of the groove, respectively. The airbag part 21 is limited by the U-shaped end 511 of the limiting block 51. Specifically, when the handbag is in the carry-on position, the limiting block 51 pops out towards the opening of the storage channel 12 under the elastic force of the limiting spring 52, aligning the U-shaped end 511 of the limiting block 51 with the opening of the storage channel 12. This allows the shoulder strap 2 to be inserted into the U-shaped end 511 of the limiting block 51, thereby locking and limiting the airbag portion 21 housed in the storage channel 12, effectively preventing the airbag portion 21 from accidentally slipping out. When it is necessary to switch from the carry-on position to the storage position... When the bag is in the shoulder bag position, by moving the limiting block 51 in the slide groove to overcome the elastic force of the limiting spring 52, the U-shaped end 511 of the limiting block 51 is misaligned with the opening of the storage channel 12, thereby releasing the lock on the airbag part 21. At this time, the shoulder strap 2 can be pulled out until the airbag part 21 is moved out of the storage channel 12. At this time, the restriction on the limiting block 51 can be released. The limiting block 51 is reset under the action of the limiting spring 52, and then the handbag is in the shoulder bag position.

[0036] When the handbag is switched from shoulder bag mode to handbag mode, the limiting block 51 is moved again to allow the airbag part 21 to enter the retraction channel 12. After the airbag part 21 is fully entered into the retraction channel 12, the limiting block 51 is reset to lock the airbag part 21.

[0037] like Figure 1 , Figures 3 to 5 ,as well as Figure 8As shown, in some embodiments of the adjustable-handle handbag, the pumping component 4 includes a pumping body 41 and a piston 42 movably disposed within the pumping body 41; an air chamber 44 is formed between the pumping body 41 and the piston 42; a push rod 43 is connected to the piston 42; and the piston 42 is provided with a first one-way valve 47 in the second air passage 45. Specifically, when the handbag is switched from a hand-carrying state to a shoulder bag state, the reel 31 drives the push rod 43 to reciprocate, and the push rod 43 drives the piston 42 to reciprocate within the pumping body 41. When the volume within the air chamber 44 decreases, the first one-way valve 47 opens, and the gas in the air chamber 44 enters the second air passage 45 through the first one-way valve 47, and then enters the air bladder 21 through the first air passage 22. When the volume within the air chamber 44 increases, the first one-way valve 47 closes, thereby ensuring the inflation effect of the air bladder 21. Thus, during the reciprocating motion of the piston 42, the air bladder 21 is continuously inflated.

[0038] like Figure 8 As shown, in some embodiments of the adjustable handle-shaped handbag, the pump body 41 has an open end; the piston 42 is provided with a second one-way valve 48 that allows the air chamber 44 to communicate unidirectionally with the outside. In this embodiment, as described above, when the volume of the air chamber 44 increases, the second one-way valve 48 opens and the first one-way valve 47 closes, allowing outside gas to be drawn into the air chamber 44 through the second one-way valve 48. When the volume of the air chamber 44 decreases, the second one-way valve 48 closes and the first one-way valve 47 opens, thereby pumping the gas from the air chamber 44 into the air bladder 21.

[0039] Of course, the pump body 41 can also be set as a hollow closed structure, with the piston 42 set inside the pump body 41 and the push rod part 43 movably sealingly passing through one end of the pump body 41. In this case, the second one-way valve 48 can be set at the other end of the pump body 41 or on the side wall of the pump body 41.

[0040] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments of the adjustable handle-shaped handbag, the take-up reel 31 is equipped with an air duct 33; one end of the air duct 33 is connected to the first air passage 22; the other end of the air duct 33 is connected to the second air passage 45 via a flexible hose 34. This embodiment achieves a sealed connection between the first air passage 22 and the second air passage 45 by providing the air duct 33 and flexible hose 34 within the take-up reel 31.

[0041] like Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, in some embodiments of the adjustable handle-shaped handbag, the outer surface of the take-up reel 31 is provided with an annular platform 311; the end of the push rod 43 away from the air chamber 44 is provided with a guide portion 431; a guide groove 432 is provided in the guide portion 431; the annular platform 311 is movably embedded in the guide groove 432; the other end of the air guide tube 33 is fixed in the annular platform 311; and the flexible hose 34 is accommodated in the guide groove 432. Specifically, when the take-up reel 31 rotates, the annular platform 311 rotates synchronously. At this time, the take-up reel 31 drives the push rod 43 to reciprocate through the annular platform 311, the annular platform 311 slides in the guide groove 432, and the flexible hose 34 ensures the communication between the first air passage 22 and the second air passage 45.

[0042] like Figure 1 and Figure 3 As shown, in some embodiments of the adjustable-handle handbag, the vent valve includes a vent 461 located on the push rod 43 and a valve plate 462 movably located on the vent 461. When the valve plate 462 closes the vent 461, the second air passage 45 is not connected to the outside; when the valve plate 462 opens the vent 461, the second air passage 45 is connected to the outside. Specifically, when it is necessary to switch the handbag from a shoulder bag state to a handbag state, the vent 461 is opened by moving the valve plate 462, thereby connecting the second air passage 45 to the outside, so that the gas in the airbag and air chamber 44 can be discharged to the outside through the second air passage 45. After the switch, the valve plate 462 can be moved back to close the vent 461, so that the second air passage 45 is not connected to the outside, so as to facilitate the pumping operation for subsequent state switching.
