However, in the lower grades of elementary school or pre-elementary school children or seniors, it is not easy to loosen and tighten the shoelaces. In addition, if both ends or the knot of the shoelace is not fixed due to violent movement or a catch by an external object during a mountain climbing, racing, or the like, the risk of injury due to a safety accident may increase. Therefore, loosening of the shoelace should be absolutely prevented.

In addition, in the case of a break, the user can only fully relax if the user can loosen the tight shoelaces. Most preferably, the user can easily tighten the shoelace, and if necessary, the user should be able to loosen the shoelace easily. At the same time, the shoelaces must be able to last tightly. Thus, a number of devices have been developed to facilitate the tightening and loosening of shoelaces that are opposite to each other.

In addition, a cover coupling groove 212 may be formed on the bottom surface of the cover insertion groove 213 so that the cover coupling protrusion 211 of the knob cover 210a is hooked.

Here, the knob cover 210a may be provided in plural sets to have various colors, patterns, and the like, and the selected image may be printed according to a user's request and sold separately from the wire fastener 200. Accordingly, the design of the knob cover 210a can be freely selected according to the user's taste, and can be easily detached from the upper surface of the knob body 210b by a hook coupling method.

In addition, a plurality of housing coupling protrusions 214 protrude from the inner circumferential lower end of the knob body portion 210b radially inward, and a ring-shaped fastening step 232 radially outward from the outer circumference of the housing portion 230.

It is preferred to be provided. In addition, the driving protrusion 215 is preferably extended to a length exceeding the lifting interval of the gear unit 220. In detail, the lifting interval is from the position of the gear unit 220 in which the gear coupling part 244 and the gear type coupling part 224 are in close contact with each other so that the reel unit 240 and the gear unit 220 rotate integrally with each other. Means the interval to the position of the gear unit 220 is separated from the gear coupling portion 244 and the gear coupling portion 224 so that 240 is free to rotate independently from the gear unit 220.

In this case, when the housing part 230 and the driving knob part 210 are combined, the driving protrusion 215 passes through the lifting hole 221 and the partition partition wall 231 and the upper surface of the reel part 240. It may be inserted into the shaft support groove 241 formed in the central portion.

That is, the driving protrusion 215 of the driving knob 210 is inserted into the shaft support groove 241 while the side wall of the driving knob 210 is rotatably supported on the outer circumference of the housing 230. Thus, the reel unit 240 may be rotatably supported.

Accordingly, since the reel unit 240 may be stably rotated without a separate rotation shaft (see 61 of FIG. 2), productivity and assembly of the product may be improved by reducing component parts. In addition, interference of the rotating shaft with respect to the connection portion between the wires (w) disposed on the lower side side fastening hollow portion 245 of the reel unit 240 can be eliminated, so the convenience of installation and replacement of the wire (w) can be improved. have.

Meanwhile, referring to FIGS. 3B to 5A, the driving protrusion 215 is provided to have an outer diameter corresponding to the inner diameter of the lifting hole 221, and the guide cam 216 is inclined upward in one direction (R) on the outer circumference. ) Is rushed.

That is, the guide cam 216 is formed to protrude stepwise radially outward from the outer periphery of the driving protrusion 215, one step (R) and the other side (CR) end side stepped surface toward one direction (R) It is formed as a slope inclined upward.

In addition, a cam groove 221a is formed at an inner circumference of the lifting hole 221 along a position corresponding to each of the guide cams 216. At this time, the cam groove portion 221a is formed to be recessed radially outward from the inner circumference of the lifting hole 221 to correspond to the radial protrusion height and the circumferential width of the guide cam 216. At the same time, the cam groove 221a is formed to be inclined upward toward one direction R to correspond to the inclined direction of the guide cam 216. That is, the cam groove portion 221a is formed to be stepped in the radially outward step from the inner circumference of the lifting hole 221, one side (R) and the other side (CR) inner surface is inclined upward toward one direction (R) It is formed into an inclined surface.

In addition, the wire fastening device 200 is provided to be selectively coupled to the reel unit 240.

First, when the driving knob 210 is rotated in the other direction (CR) in the state in which the gear unit 220 is lowered as shown in FIG. 5A, the step surface of the other direction (CR) of the guide cam 216 is cam. The inner surface of the groove portion 221a is in contact with the other direction CR.

Here, the gear unit 220 is constrained to rotate in the other direction (CR) through the bite between the ratchet coupling portion 223 of the elastic wing portion 220b and the ratchet type gear 233 of the housing 230. It is a state. Therefore, the guide cam 216 presses the inner surface of the other direction CR of the cam groove 221a in the upward diagonal direction to the other direction CR through the inclination of the step surface of the other direction CR. Accordingly, as shown in FIG. 5B, the gear part 220 slips in the diagonal direction along the other step CR step surface of the guide cam 216 in the other direction CR of the cam groove part 221a. It can be moved and raised.

In this case, the gear coupling portion 244 and the gear coupling portion 224 may be spaced apart from each other. In addition, the reel unit 240 may be detached from the gear unit 220 and converted into a freely rotatable state to pull the wire w wound around the reel unit 240. That is, coupling coupling of the reel unit 240 and the gear unit 220 is released. In addition, the tightening object may be switched to an unwinding state as the wire w of the reel unit 240 is unwinding.

To this end, the ratchet-type gear 233 is preferably provided with a height plus the lifting interval to the height of the ratchet coupling portion 223 in the vertical direction. In addition, the gear unit 220 may be elevated while maintaining the ratchet-type gear 233 and the ratchet coupling unit 223 are bitten each other.

Also, referring to FIGS. 4A to 7, the tension protrusion 217 may be provided at the lower surface of the driving knob unit 210. In this case, the tension protrusion 217 is provided so that the guide cam 216 and the cam groove 221a are separated and rotated at a predetermined angle when one direction R is rotated for coupling the gear unit 220. desirable. In addition, the tension protrusion 217 is preferably provided to press the ratchet coupling portion 223 radially outward when the other direction (CR) rotates.

In addition, a click protrusion 217b in which the upper end and the lower end of the elevating gear unit 220 are shot and latched may be protruded from the inner surface portion of the tension protrusion 217. In detail, the tension protrusion 217 protrudes downward from the lower surface of the drive knob 210 so as to be disposed between the outer circumference of the gear body portion 220a and the inner circumference of the elastic wing portion 220b.

At this time, the tension protrusion 217 is an outer circumferential surface is disposed to be spaced apart from the inner circumference of the elastic wing portion 220b, it is preferable that the inner circumferential surface is provided with a size in close contact with the outer circumference of the gear body portion (220a).

In addition, the tension protrusion 217 is provided to elastically deform inward and outward in the radial direction. The click protrusion 217b protrudes radially inward at a position corresponding to the upper edge of the gear body 220a when the gear unit 220 descends, and the upper end and the lower end are inclined. .

At this time, when the gear unit 220 is elevated, the upper and lower edges of the gear body portion 220a incline and press the upper and lower ends of the click protrusion 217b. Accordingly, the tension protrusion 217 may be elastically deformed radially outward along the clearance space between the elastic wing portion 220b and the gear body portion 220a.

When the lifting of the gear unit 220 is completed, the tension protrusion 217 is radially restored to the inner side, and the upper and lower edges of the gear body 220a are the upper end of the click protrusion 217b and It can be elastically supported by the lower end.

Accordingly, even when the external force is released after the driving knob 210 is operated in the other direction R, the rising state of the gear unit 220 may be stably maintained. In addition, in the state in which the reel 240 is free to rotate, the wire (w) can be easily pulled out to improve the ease of use of the product.

In addition, the elastic protrusion 220b protrudes on the inner circumferential surface of the other end side provided with the ratchet coupling portion 223 so as to overlap the rotational trajectory of the tension protrusion 217. At this time, the pressing protrusion 225 is opposed to the tension protrusion 217 at an angle at which the gear type coupling part 224 of the gear part 220 is completely separated from the gear coupling part 244 of the reel part 240. It is preferably formed at an angle to be.

That is, when the driving knob 210 is rotated in the other direction (R) and the gear unit 220 is raised, the pressing protrusion 225 of the elastic wing portion 220b is radiused by the tension protrusion 217. Is pushed outward. In addition, the ratchet coupling portion 223 and the ratchet type gear 233 may be more stably bite, and the clearance space between the elastic wing portion 220b and the gear body portion 220a may be removed.

As such, the gear unit 220 may move up and down when the driving knob unit 210 rotates through the guide cam 216 and the cam groove unit 221a which are inclined diagonally. Here, when the driving knob 210 is rotated in the other direction, the tension protrusion 217 presses the elastic wing portion 220b to the radially outer side. Accordingly, when the driving knob 210 rotates in one direction for the lowering of the gear unit 220, the interlocking rotation of the gear unit 220 may be blocked. That is, since the driving knob 210 may be rotated separately from the gear unit 220 at a predetermined clearance angle, the lifting state of the gear unit 220 may be accurately switched.

On the other hand, in the state in which the gear unit 220 is raised, the elastic wing portion 220b is pressed by the tension projection 217, the play between the elastic wing portion 220b and the gear body portion 220a. When the space is removed, rotation of the gear unit 220 in one direction R is limited.

Here, the drive knob 210 is provided to be separated and rotated in one direction (R) at a predetermined clearance angle from the gear unit 220. To this end, between the deformation limiting protrusion 226 protruding from the outer circumference of the gear body portion 220a and the pressing protrusion 225 protruding from the inner circumference of the elastic wing portion 220b are spaced apart by the clearance angle or more. desirable.

At this time, when the driving knob 210 is rotated in one direction (R), the one-way (R) step surface of the guide cam 216 is in contact with the inner surface of the one direction (R) of the cam groove (221a). Here, since the gear unit 220 is in a state in which rotation of one direction (R) is restricted, the guide cam 216 has one inner side (R) inner surface of the cam groove portion 221a through the inclination of the one direction (R) step surface. Press in one direction (R) side downward diagonal direction.

Accordingly, as shown in FIG. 5A, the inner surface of the one direction R of the cam groove 221a is slid in a diagonal direction along the one step R step surface of the guide cam 216, so that the gear unit 220 is moved. Can be lowered.

When the gear part 220 is lowered, the gear type coupling part 224 and the gear coupling part 244 mesh with each other and are coupled to the reel part 240. At this time, the tension protrusion 217 is separated from the pressing protrusion 225 in one direction (R), since the restrained state of the elastic wing portion 220b is released, the gear unit 220 is the drive knob portion ( It may be rotated in one direction (R) integrally with the 210.

In addition, the vertical cross-section of the other side (CR) side of the gear coupling part 244 is engaged with the vertical cross-section of the one direction (R) side of the gear type coupling part 224, so that the wire w is the gear portion 220. And reel unit 240 is integrally rotated in one direction (R) can be wound.

As such, the driving knob 210 and the gear unit 220 are provided with the guide cam 216 and the cam groove portion 221a which are formed to be inclined upward toward one direction R to be engaged with each other. In addition, the guide protrusion 217 and the cam groove 221a may be selectively separated and rotated through the tension protrusion 217.

Accordingly, when one of the guide cam 216 and the cam groove 221a is rotated, the other is slip-moved in the diagonal direction. In addition, only two parts may be operated to lift and lower the coupling and release states of the gear unit 220 and the reel unit 240, thereby reducing the number of parts and improving the productivity of the product.

On the other hand, in the state that the wire (w) is wound on the reel unit 240, when the user is applied to the external force such as moving to the state wearing the tightening object or forcibly pulling the wire (w), the reel unit 240 The other direction (CR) rotational force is applied.

At this time, since the reel unit 240 is coupled to the gear unit 220, the other direction (CR) rotational force of the reel unit 240 is perpendicular to the other direction (CR) side of the gear coupling unit 244. It is transmitted to the vertical section in one direction (R) side of the gear coupling portion 224 along the cross section. At this time, since the gear part 220 is in a state in which rotation of the other direction (CR) is constrained by engaging the ratchet coupling part 223 and the ratchet-type gear 233, forced loosening of the wire w may be prevented. have.

4B to 5A, it is preferable that the guide cam 216 has a stopper step portion 216a formed along an end portion of the guide cam 216 which is disposed to face the edge of the cam groove 221a when the direction R is rotated. . That is, the stopper stepped portion 216a recessed to be stepped upward is formed at the lower end of the one direction R side of the guide cam 216 disposed opposite the one direction R side edge of the cam groove 221a. In this case, the stopper step portion 216a is formed in a state in which the gear portion 220 and the reel portion 240 are rotated to be coupled to each other.

At this time, the stopper stepped portion 216a has a horizontal direction along the height corresponding to the top edge of the cam groove 221a when the one-sided (R) side edge of the guide cam 216 is lowered. It can be formed open.

Accordingly, when the driving knob 210 rotates in one direction R, the stopper step 216a is seated on the upper edge of the one direction R side of the cam groove 221a to lower the gear unit 220. State can be maintained. That is, the driving knob 210 is rotated in one direction R while the gear unit 220 is raised. Accordingly, the gear unit 220 is lowered in one direction (R) side inner surface of the cam groove 221a slides along the step surface of the one direction (R) side of the guide cam 216.

At this time, when the gear unit 220 is lowered to engage the gear coupling unit 224 and the gear coupling unit 244, the stopper step 216a may be formed at the upper edge of the one-way side of the cam groove unit 221a. It is seated. Accordingly, the gear unit 220 may be prevented from malfunctioning due to movement shocks, etc., instead of the user's direct manipulation. That is, in the state in which the gear part 220 is lowered, the driving protrusion 215 is rotated in the other direction (CR) so that the edge of the cam groove part 221a is separated from the stopper stepped part 216a. In addition, ascending of the gear unit 220 may be started when the inner side surface of the cam groove 221a is in contact with the step surface of the other side CR of the guide cam 216. .

At this time, the rotation angle of the driving knob 210, the maximum overlap angle between the edge of the stopper step 216a and the cam groove 221a for switching between the rising state and the falling state of the gear unit 220 The sum is preferably set below the clearance angle.

As such, even when the gear unit 220 or the driving knob unit 210 is vibrated in the up-down direction or the left-right direction due to the impact of the movement, the flat lower surface portion of the stopper step 216a is the cam groove part 221a. Support the upper side of the edge side.

Therefore, the falling state of the gear unit 220 can be stably maintained, and the sudden unwinding of the wire (w) due to a false rise or the like of the gear unit 220 and a safety accident caused by this prevent the safety of the product. Can be improved.
