When the front end of the lace (L) is pulled down, since the upper end portion of the lace (L) downwardly pressurizes the lower end portion of the lace (L) , the lace (L) can keep a tightly fastened state without being loosened from the second fastening part 200.
As described above, in a state where the lace (L) is fastened and fixed to the second fastening part 200, a user grasps the receiving member 110 and the fastening member 130, and then, inserts the fastening member 130 into the receiving space 111b.
When the fastening member 130 is fastened to the receiving space 111b while passing the control protrusion 121c of the control member 120 made of the metal material, the control protrusion 121c of the control member 120 is rotated on the rotary shafts 121a by the fastening slots 131a of the fastening member 130, and at the same time, restored by a magnetic force of the magnetic body 140. The fastening member 130 is fastened to the receiving space 111b while repeating the above steps.
Here, the control member 120 may have the control board 121 entirely made of the metal material or partially made of the metal material, namely, only a portion closely contacting with the magnetic body 140 is made of the metal material.
Furthermore, to release the fastened state of the first fastening part 100, when the control levers 121b formed at both sides of the control member 120 are rotated on the rotary shafts 121a, the control board 121 is rotated on the rotary shafts 121a, so that the control protrusion 121c is released from the fastening slots 131a of the fastening member 130 and the control board 121 is separated from the magnetic body 140 simultaneously.
As described above, when the control member 120 is rotated, the fastening member 130 is outwardly separated from the receiving member 110. After the separation of the fastening member 130, when the rotation of the control levers 121b is removed, the control member 120 is restored to the original state by the magnetic force of the magnetic body 140. Additionally, to release the fastened state of the lace (L) from the second fastening part 200, when the user grasps the upper end portion of the lace (L) and pulls up it to the upper portion of the guide space 212, the pressurizing force pressurizing the lower end portion of the lace (L) is removed, so that the lace (L) can be relaxed since the lower end portion of the lace (L) can be freely moved.
Moreover, another preferred embodiment of the present invention will be described as follows.
First, as shown in FIG. 9 or 10, in a state where the receiving member 310 and the fastening member 320 are fastened with each other oppositely to the lace (L) , the user grasps the receiving member 310 and the fastening member 320 with a hand, and then, inserts the fastening member 320 to the coupling space 311a of the receiving member 310.
In this instance, the retaining protrusion 321 of the fastening member 320 is in contact with the release piece 316 and fastened to the receiving member 310 while moving forward, and the release piece 316 supports the retaining protrusion 321 inclinedly protruding in one direction while contacting with the retaining protrusion 321 by elasticity of the plate spring 317, so that the fastened state between the receiving member 310 and the fastening member 320 can be kept without release .
As described above, to take off the footwear 10 in a state where the third fastening part 300 is fastened to the footwear and the footwear is tightened, when the user grasps the receiving member 310 and presses the pressing piece 315 of the receiving member 310 downwardly, the pressurizing piece 314 having the semicircular section pressurizes a portion of the release piece 316, so that the release piece 316 is rotated toward the upper portion of the body 311 by the pressurizing piece 314 and separated from the retaining protrusion 321, whereby the fastened state can be released.
After that, the user rotates the receiving member 310 and the fastening member 320 toward both sides of the footwear 10 to laterally relax the footwear 10, so that the user can rapidly and easily take off the footwear.
Since the third fastening part 300 can be reduced and increased in its size according to the number of the connection links 318 and 322 formed at both sides of the receiving member 310 and the fastening member 320, the lace fastening device according to the present invention can be applied to small footwears, which children wear, and to footwears having long ankle portions, such as mountain- climbing boots, military shoes, work shoes, and so on, and fasten the lace to the shoe while selectively controlling tightening and release, [industrial Applicability]
As described above, 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.
