Device for tying shoelaces

The present invention relates to a footwear, and more particularly, to such a lace fastening device, which is easy to mount and detach and simple in structure since a control member rotated while a fastening member is fastened to the inside of a receiving member is restored by a magnetic body, and which can keep a stable fastened state since the upper end portion of a lace fastened to a second fastening part pressurizes the lower end portion of the lace.

In general, a footwear is one of life goods used in daily life, and recently, their use has been greatly increased due to an increase of people\'s social activities or leisure time period owing to five working days per week. Such footwears have various kinds according to their use purposes, but people can wear most of footwears using laces without regard to their use purposes.

The footwear 10 includes a body 11 having a receiving space 12 for receiving and protecting a user\'s foot, a protective cover 13 located on an opened instep portion of the body 11 for protecting the top of the user\'s foot, and connection links 14 oppositely arranged on both sides of the instep portion of the body 11 at regular intervals and fixed to the footwear 10 via fixing members 15, whereby a lace (L) is cross-fastened to the footwear.

However, the conventional footwear as constructed above has several problems in that it is complicated and takes much time to wear and unwear the footwear since the user has to tightly pull the laces after untying and slackening the laces to wear the footwear, and in that the laces may be loosened while the user walks, and in that the outward appearance is not good since knots of the laces are complex when the laces are tied.

Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a lace fastening device, which is easy to use and simple in structure since a fastening member is released from a fastened state while a control member is separated from a magnetic body since the magnetic body is mounted inside a receiving member, and which can keep a stable fastened state of a lace since the upper end portion of the lace fastened to a second fastening part pressurizes the lower end portion of the lace.

To achieve the above objects, the present invention provides a lace fastening device for a footwear worn on a user in such a manner that a lace is cross-fastened to connection links oppositely formed on an instep portion of the footwear at regular intervals, comprising: a first fastening part fastened between the connection links to which the lace is connected and having a fastening member fastened to the inside of a receiving member while rotating and restoring a control member, the first fastening part releasing the fastened state of the fastening member while rotating the control member to separate it from a magnetic body; and a second fastening part to which an end portion of the lace passing the final connection link of the footwear is fit to and stackingly connected to the inside of a fixing member, so that the second fastening part can keep a tightly fastened state of the lace while the upper end portion of the stackingly connected lace pressurizes the lower end portion of the lace.

The lace fastening device according to the present invention is easy to mount and detach and simple in structure since a control member rotated while a fastening member is fastened to the inside of a receiving member is restored by a magnetic body, thereby reducing the manufacturing cost. Moreover, the lace fastening device can rapidly fasten the lace to the shoe and keep a stable fastened state since the upper end portion of the lace fastened to the second fastening part pressurizes the lower end portion of the lace, thereby improving productivity.
