Abstract
Description
[Technical field]
[0001] The present invention relates to a device for opening and closing a urination opening in pants, and more specifically to a device for opening and closing a urination opening in pants which uses a magnet to automatically close the urination opening, but which eliminates poor usability by covering the magnet with a synthetic resin film to prevent corrosion during the washing process and forming a large number of fine protrusions that leave gaps between the magnets to prevent body hair from getting caught between the magnets. [Background technology]
[0002] Generally, men's underwear pants are provided with a urination opening so that men can urinate comfortably without having to pull down their pants, and such a urination opening is opened and closed using a button and a buttonhole. However, because the process of fastening the button to the buttonhole is very cumbersome, in most cases, men often leave the button undone in the buttonhole and urinate in that state, or have to pull down their trousers and underwear before urination.
[0003] In view of the above circumstances, the conventional Korean Registered Utility Model Publication No. 289502 proposes an automatic urinary opening closing structure for men's pants in which a magnet is attached to the back fabric forming the urinary opening of the pants, and an iron piece is attached to the front fabric, so that the magnet and the iron piece stick together to keep the urinary opening automatically closed at all times except when the urinary opening is in use. When it is time to urinate, the magnet and the iron piece can be pulled apart with a small force, allowing the urinary opening to be easily opened and urinary opening to be opened, and after urination, the magnet and the iron piece automatically stick together to automatically close the urinary opening, allowing the pants to be worn in a neat state and improving the appearance of outerwear.
[0004] However, the conventional Korean registered utility model products had the disadvantage that because the magnet and iron piece were exposed, corrosion occurred during repeated washing, causing rust stains on the fabric, resulting in complaints from consumers. In addition, because there was no gap where the magnet and iron piece were in contact, when pulling up one's pants after urinating, any body hair sticking out from the urination opening would get caught between the magnet and the iron piece, resulting in the hair being pulled out or pulled out when moving, causing pain and making the products difficult to use. Summary of the Invention [Problem to be solved by the invention]
[0005] The present invention was devised in view of the conventional situation, and its object is to relate to a device for opening and closing a urination opening in pants, which uses two magnets or a magnet and a metal to automatically close the urination opening, and which is covered with a synthetic resin film to prevent corrosion during the washing process, and which has a large number of fine protrusions that leave gaps between the magnets or between the magnet and the metal to prevent body hair from getting caught, thereby preventing the pain of having body hair pulled or pulled out. [Means for solving the problem]
[0006] For this reason, one embodiment of the present invention is a device for opening and closing a urination opening in pants, in which a magnet is fixed to the lining of the urination opening in pants, and a magnetic body made of a magnet or metal is fixed to the front fabric, and the urination opening is opened and closed via the magnet and magnetic body, wherein the magnet and magnetic body are protected from corrosion via a coating portion covered with a synthetic resin film, and each of the coating portions extends to the outer periphery of the magnet and magnetic body and is then attached to the lining and front fabric via a sewn portion. Effect of the Invention
[0007] According to the present invention, the magnet and metal that closes the urination opening are covered with a synthetic resin film, which has the advantage of preventing corrosion during the washing process. Also, since fine protrusions are formed on the film, gaps are formed between the magnets or between the magnet and the metal, and body hair can easily slip through these gaps. Therefore, body hair does not get caught between the magnet and the metal when putting on pants after urination, so there is no pain from body hair being pulled or pulled out while sitting or walking, which has the advantage of being comfortable to wear.

[0009] In the opening and closing device of the first embodiment of the present invention shown in Figures 1 and 2, a magnet 20 is sewn to the lining fabric 10 of the urination opening, and a magnetic body 21 made of a magnet or metal is sewn to the front fabric 11. The magnet 20 and magnetic body 21 have a coating portion 30 covered with a synthetic resin film. The coating portion 30 has a thickness that does not impede the magnetic force of the magnet 20 from being directed toward the magnetic body 21, and two sheets of synthetic resin film may be closely attached to each other on both sides of the magnet 20 and the magnetic body 21 and heat-bonded, or may be sealed while being contained in a bag-shaped film.
[0010] The coating portion 30 extends to the outer periphery of the magnet 20 and the magnetic body 21, and the extended portion is sewn to the inside of the lining fabric 10 and the outer fabric 11 via the sewing portion 40. Therefore, the magnet 20 and the magnetic body 21 are not exposed to the outside of the fabric. In addition, the coating portion 30 enveloping the magnet 20 has a number of fine protrusions 31 formed on its surface, so that a gap is formed between the magnetic body 21 and the magnet 20. Therefore, the body hair can easily slip out along the gap between the magnet 20 and the magnetic body 21, so that the body hair is not pulled out or pulled during the process of closing the urination opening of the pants.
[0011] FIG. 3 shows a second embodiment of the present invention, which has the same configuration as the first embodiment of the present invention, except that the outer peripheral edge of the coating portion 30 that encases the magnet 20 and the magnetic material 21 is sewn to the outside of the lining fabric 10 and the front fabric 11 via a sewing portion 40.
[0012] FIG. 4 shows a third embodiment of the present invention, in which the magnet 20 and the magnetic body 21 are configured in a ring shape with a through hole 22 in the center, and the magnet 20 and the magnetic body 21 have a coating part 30 coated with a synthetic resin film. The through holes 22 are closed by the coating part 30, and the coating part 30 covering each through hole 22 and the back fabric 10 or the front fabric 11 are connected via a rivet joint 41, so that the magnet 20 and the magnetic body 21 are fixed to the fabric. The coating part 30 covering the magnet 20 has a number of fine protrusions 31 formed on its surface, so that a gap is formed between the magnetic body 21 and the magnet 20. Therefore, the hair can easily slip out along the gap between the magnet 20 and the magnetic body 21, and the hair is not pulled out or pulled out during the process of closing the urinary opening of the pants.
[0013] 5 shows a fourth embodiment of the present invention, which has the same configuration as the third embodiment. The difference is simply that the rivet joint 41 is not used for the coating part 30 that closes the through part 22, and the magnet 20 and the magnetic body 21 are fixed to the respective fabrics 10, 11 via the sewn part 40.
[0014] FIG. 6 shows a fifth embodiment of the present invention, in which the magnet 20 and the magnetic body 21 have a coating portion 30 covered with a synthetic resin film, and the magnet 20 and the magnetic body 21 are fixed by wrapping the opposing surfaces of the magnet 20 and the magnetic body 21 with a covering ring 50 made of a non-corrosive non-ferrous metal. The outer periphery of each of the covering rings 50 faces the substrates 10 and 11 in a direction indicated by the arrows " JPEG2025510820000002.jpg1210"-shaped fixing groove 52. In the process in which a fixing ring 60 having a fixing piece 61 is crimped to the covering ring 50 side of each of the fabrics 10, 11, the fixing piece 61 is crimped into the fixing groove 52, and the magnet 20 and the magnetic body 21 are fixed to the back fabric 10 and the front fabric 11 via the fixing ring 60 and the covering ring 50.
[0015] In addition, the covering ring 50 to which the magnet 20 is fixed has a number of fine protrusions 51 formed on the surface facing the magnetic body 21, so that the covering rings 50 on both sides do not adhere to each other but have a gap therebetween. Therefore, the body hair can easily slip out along the gap between the magnet 20 and the magnetic body 21, and the body hair will not be pulled out or pulled out during the process of closing the urination opening of the pants.
[0016] 7 shows a sixth embodiment of the present invention, in which the magnet 20 and the magnetic body 21 are configured in a ring shape with a through-hole 22 in the center, and have a coating portion 30 covered with a synthetic resin film. The magnet 20 and the magnetic body 21 are fixed by wrapping the opposing surfaces via a covering ring 50 made of a non-ferrous metal that does not corrode, and each covering ring 50 is configured to extend to the through-hole 22 and block the through-hole 22, and a pin hole 53 communicating with the through-hole 22 is drilled in the center of each covering ring 50. In the process in which a fixing ring 60 having a fixing pin 62 is crimped to the covering ring 50 side, the fixing pin 62 is crimped into the pin hole 53, and the magnet 20 and the magnetic body 21 are fixed to the back fabric 10 and the front fabric 11 via the fixing ring 60 and the covering ring 50.
[0017] In addition, the covering ring 50 to which the magnet 20 is fixed has a number of fine protrusions 51 formed on the surface facing the magnetic body 21, so that the covering rings 50 on both sides do not adhere to each other but have a gap therebetween. Therefore, the body hair can easily slip out along the gap between the magnet 20 and the magnetic body 21, and the body hair will not be pulled out or pulled out during the process of closing the urination opening of the pants.
