Definitions

  • the present disclosure relates to a shoelace loosening prevention device and, more particularly, to a shoelace loosening prevention device that can prevent a shoelace fastened to a shoe from loosening by conveniently fixing the shoelace even without tying or loosening a knot of the shoelace.
  • shoelaces are generally used as one of instruments for tightening shoes, such as various kinds of sports shoes, to fit to the feet of a user.
  • Such shoelaces thread and fasten several holes arranged at the instep and ankle parts of a shoe and the remaining portions are fastened and knotted at the ends, thereby finishing fastening. Accordingly, there is inconvenience that a user has to tie or untie a knot on a shoe when fastening or unfastening a shoelace to a shoe.
  • Such devices for tightening a shoelace are configured such that a space is secured between a moving saw tooth part and a fixed tooth part when a pressing rod or a protruding rod is pressed, and the moving saw tooth part and the fixed tooth part are engaged with each other by elasticity of a spring or an elastic bar, which is an elastic member, when the pressure is removed after a shoelace is moved to an appropriate position to be fixed inside, thereby being able to simply fix the shoelace and prevent the shoelace from loosening even without fixing the shoelace and making a knot.
  • these inventions have a problem that pressure should be horizontally applied to form a gap between the moving saw tooth part and the fixed tooth part when applying pressure to secure a space between the moving saw tooth part and the fixed tooth part, but, the pressing rod or the protruding rod that is supposed to be held by one finger is formed over the moving saw part, so when the pressing rod or the protruding rod is pressed by a finger, pressure is not accurately horizontally applied and applied at an angle. Accordingly, a large force is required for applying pressure, so this work is not only difficult, but overworks a finger.
  • these inventions have a problem that since shoelace holes of the flat-type devices for tightening a shoelace are arranged on sides of the front part, when a user puts on a shoe with the shoelace inserted and fixed inside, the rear of the devices is lifted perpendicularly to the instep part of the shoe due to tension that is applied to the shoelace, which is bad for the aesthetic appearance. Further, since the rear is lifted and protrudes, the devices and the shoelace coming out of the holes get in the way, which is inconvenient and causes a pain by applying pressure to a specific part.
  • these inventions have a problem that when the remaining part of a shoelace fastened to a shoe is long, the remaining part should be inserted in the device and the part of the shoelace protruding out of the holes should be knotted or fitted in the space inside the shoe, that is, it is inconvenient to finish the end of the shoelace.
  • an objective of the present disclosure is to provide a shoelace loosening prevention device having a structure that can easily horizontally apply pressure for forming a gap between a moving saw tooth part and a fixed saw tooth part when applying pressure to secure a space between the moving saw tooth part and the fixed saw tooth part.
  • another objective of the present disclosure is to provide a shoelace loosening prevention device that can be in close contact with the instep part of a shoe without being lifted even if tension is applied to a shoelace when a user puts on a shoe with the shoelace is inserted and fixed inside.
  • another objective of the present disclosure is to provide a shoelace loosening prevention device that can insert a remaining part therein and can easily fix and finish the end of a shoelace that protrude out of a hole when the remaining part of the shoelace fastened to a shoe is long.
  • a shoelace loosening prevention device includes a casing member including: a cover part that has a front end cut-portion and a rear end cut-portion; a bottom that has a drawing-out member fixing portion, a guide hole that is an oblong hole formed in a front-rear longitudinal direction, and a rear end cut-portion that is a cut groove corresponding to a shape of the rear end cut-portion of the cover part, which are sequentially formed with predetermined gaps from a front end to a rear end; sides that are disposed in a pair to connect sides of the cover part and the bottom to each other, respectively, and have two fixed pressing-protrusions formed inside thereof, respectively, to face an inside of the casing member and face each other, and formed such that a gap therebetween decreases from a front end to a rear end; and rear parts that are formed in a pair and spaced apart from each other by cutting a center portions to connect rear ends of the cover part and the bottom to each other,
  • the feeding member may include a grip having a pressing member coupling portion formed at a front end thereof and coupled to the feeding member coupling portion.
  • the casing member may have an additional guide hole formed at the cover part and corresponding to the guide hole of the bottom
  • the pressing member may have an additional guide protrusion insertion hole that is a coupling groove formed in the top
  • the feeding member may have an additional top coupled to an upper portion of the grip and an additional guide protrusion protruding downward from a front end of the top and sequentially inserted in the additional guide hole and the guide protrusion insertion hole.
