[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0016] like Figure 1The image shows the leg opening of the pants body 10. A type of free-form trousers includes a pants body 10, on which are provided a connector 20, a first fastener 30, a second fastener 40, a third fastener 50, and an adjusting cord 60. The connector 20 is located at the lower leg of the pants body 10. The first fastener 30, the second fastener 40, and the third fastener 50 are arranged along the circumference of the pants body 10 at the height of the connector 20. The connector 20 is used to connect with the first fastener 30, the second fastener 40, and the third fastener 50. The trouser body 10 is detachably connected to any one of the third fasteners 50, thereby adjusting the circumference of the lower leg. The leg opening of the trouser body 10 is folded inward to form an adjustable leg opening 11. An adjustment channel 12 is formed inside the adjustable trouser body, and an outlet 13 communicating with the adjustment channel 12 is provided. An adjustment rope 60 is disposed inside the adjustment channel 12 and extends to the outside from the outlet 13. A rope buckle 70 is provided on the adjustment rope 60, which is used to change the length of the adjustment rope 60 within the adjustment channel 12, thereby changing the circumference of the leg opening. This application allows the lower leg of the trouser body 10 to have different circumferences by fixing it with the connector 20 and different fasteners, allowing women to wear the same pair of trousers to create different styles of trousers, thus adapting to different occasions. The distances between the first fastener 30, the second fastener 40, and the third fastener 50 and the first moving part increase sequentially. When wearing them normally, fastening the nearest first fastener 30 will make them look like banana pants; fastening the second fastener 40 will make them look like wide-leg pants; fastening the third fastener 50 will make them look like bell-bottom pants. When wearing them outdoors, the connector 20 can be fixed to the second fastener 40 and then the adjustable rope 60 can be used to adjust the adjustable pant leg 11.
[0017] The first fastener 30, the second fastener 40, and the third fastener 50 are all buttons, and the connecting piece 20 is a buckle. The buckle is detachably connected by slipping onto the button, thereby adjusting the circumference of the lower leg of the pants body 10.
[0018] The first fastener 30, the second fastener 40, and the third fastener 50 are all female fasteners, and the connector 20 is a female fastener. Of course, the specific connection structures of the fasteners and connector 20 can be interchanged, as long as a detachable connection is achieved. The structure of the female and male fasteners is not shown in the attached drawings.
[0019] like Figures 1-3As shown, the connector 20, the first fastener 30, the second fastener 40, and the third fastener 50 are all located inside the pants body 10. This internal placement allows the pants to appear similar to ordinary pants from the outside, while simultaneously providing adjustment for the pant body 10's circumference. This concealed design also allows the adjusted pants body 10 to more closely resemble banana pants, wide-leg pants, and flared pants, resulting in greater authenticity, a wider appeal, and improved practicality and aesthetics. To use, fold the pants body 10 up, secure the connector 20 and its corresponding fastener, then fold the pants body 10 down to adjust its circumference. With practice, the connector 20 and its corresponding fastener can also be secured directly from the outside.
[0020] The trouser body 10 has a through hole 14 on the side of the connector 20 near the first fixing member 30. The trouser body 10 also has through holes 14 on both sides of the first fixing member 30, the second fixing member 40, and the third fixing member. The through holes 14 allow the connector 20 to pass through before connecting to any one of the first fixing member 30, the second fixing member 40, or the third fixing member. Without the through holes 14, the pleats of the trouser body 10 would face outwards after the connector 20 is connected to the fixing member. With the through holes 14, the connector 20 passes through the through holes 14 before connecting to the corresponding fixing member, so the pleats of the trouser body 10 face inwards. This results in a higher degree of realism and a more aesthetically pleasing appearance.
[0021] like Figure 4 As shown, the outlet 13 of the adjustable leg opening 11 is located inside the leg body 10. The internal location of the outlet 13 allows the adjusting cord 60 to face inwards towards the leg body 10, effectively concealing it and allowing the leg body 10 to fit more snugly to different types of pants after deformation, resulting in better fit and aesthetics. There can be one or two outlets 13. The adjusting cord 60 is looped, and its length within the adjustable leg opening 11 is adjusted via a cord buckle 70, thereby changing the circumference of the adjustable leg opening 11. The cord buckle 70 is existing technology; when pressed, it can move on the adjusting cord 60, and when released, a spring presses it to fix the cord buckle 70 on the adjusting cord 60, thus limiting the displacement of the adjusting cord 60 within the adjustable leg opening 11.
[0022] The pants body 10 has a holder 15 for placing the adjustment cord 60. There are multiple holders 15, which are located at different heights above the outlet 13.
[0023] The placement piece 15 is a button. After the circumference of the adjustable trouser leg 11 is reduced, the adjustment cord 60 will be pulled out to a certain length, which may easily protrude outside the trouser body 10. With the placement piece 15, the adjustment cord 60 can be wrapped around the placement piece 15. The placement piece 15 is set with multiple different heights, so that the adjustment cord 60 with different pulled-out lengths can be wrapped at a suitable height.
[0024] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
