The second binding teeth 122 'are formed radially on the upper surface of the spool 120' so as to be engaged with the second binding teeth 142 of the rotating member 140 to be described later, And the rotational force of the rotary member 140 is not transmitted when the second coupling teeth 142 are separated from the second coupling teeth 142 of the rotary member 140. At this time, although the three second coupling teeth 122 'in the present embodiment are formed to be equally spaced, the number of the second coupling teeth 122' may be increased or decreased.

The third and fourth wire fixing holes 124a 'and 124b' are fixed to the circumferential surface of the spool 120 'so that both ends of the wire W are respectively knotted so that the spool 120' the wire W in the unroll state is wound while being switched to the roll state.

In other words, the third wire fixing holes 124a 'are each formed in the transverse direction at both opposite ends of the spool 120', and the fourth wire fixing holes 124b'-1 and 124b'- Are formed in the lateral direction on the upper side and the right side of the third wire fixing hole 124a ', respectively.

The fourth wire fixing hole 124b'-1 formed at one side of the fourth wire fixing holes 124b'-1 and 124b'-2 is formed at the upper portion of the third wire fixing hole 124a ' And the fourth wire fixing holes 124b'-2 formed on the other side are spaced apart in the horizontal direction between the third wire fixing holes 124a 'and the one fourth wire fixing holes 124b'-2 Respectively.

The reason why the other fourth wire fixing hole 124b'-2 is formed at the center of the third wire fixing hole 124a 'and the one fourth wire fixing hole 124b'-1 is that the wire W Is positioned at the center position of the first folded portion (F1) when the end of the first folded portion (F1) is inserted into the first folded portion (F1) So as to facilitate insertion into the inside.

Furthermore, the third wire fixing hole 124a 'and the fourth wire fixing holes 124b'-1 and 124b'-2 are formed in a circular shape.

Here, the wire W fixed to the spool 120 'passes through one end of the third wire fixing hole 124a' and then folds in the opposite direction, as shown in FIGS. 18 and 19, Passes through the fourth wire fixing hole 124b'-1 in the state where the folded portion F1 is formed and then passes through the other end of the fourth wire fixing hole 124b'-2 and the second folded portion F2 And is positioned and fixed within the first folded portion F1 in a formed state. Thereafter, the end portion of the wire W, which is positioned inside the first folded portion F1 and is fixed, is cut by a tool or the like in a portion extending in a state of being forcedly fitted inside the wire fixing projection 126 '.

The wire fixing projections 126 'are spaced apart from each other at both ends of the inner top surface of the spool 120' parallel to the direction in which the end of the wire W is inserted into the third wire fixing hole 124a ' The ends of the wafers W are forcedly inserted so as not to interfere with the connection shaft 130, which is a neighboring structure according to the exposure.

The wire reel 100 according to the present invention functions to firmly fasten an article through a wire and can be used for shoes such as a shoe, a hat or other hair worn, a belt, a glove, a helmet, a backpack, It can be variously applied to the binding of boots or objects used for skiing or snowboarding, and the wrist guards for bowling.

Meanwhile, although not shown in the drawing, when the wire reel 100 according to the present invention is applied to a bowling wrist protector, in the process of adjusting the band to fit the wrist or the finger by the Velcro tape, When the wrist is thick, the Velcro tape can not be fixed firmly because the adhesive area of the Velcro tape is not enough. It is possible to adjust the band to correspond to the thickness of the wrist, and it can be easily worn by one hand.

As described above, the wire reel 100 according to the present invention has a structure in which, when the restraint member is lowered, the impact generated during the collision with the ratchet gear formed in the housing, The impact caused by repeated engagement of the restraint member with the ratchet gear when the cover is rotated and the restraint member interlocked with the cover rotates due to the load generated during the process of supporting the ratchet gear of the housing by the teeth of the restraint member, In the present invention, since the restraint member is detachable from the rotary member, the problem can be solved.

Therefore, the operation of the wire reel 100 according to the present invention is as follows.

First, when operation is required to tighten the object, if the user rotates the handle cover 170 in one direction (for example, clockwise) while grasping the handle cover 170, the rotation member 140 ) Are rotated together.

The binding cover 144 of the rotating member 140 is positioned below the protruding portion 132 of the connecting shaft 130 in a state where the rotating member 140 which is raised and lowered by the interlocking operation is lowered A second coupling tooth 142 formed on the bottom surface of the rotary member 140 is engaged with a first coupling tooth 122 formed on the upper surface of the spool 120 so that the rotation of the rotary member 140 during rotation of the spool 120 And the wire W can be wound around the spool 120 while being rotated.

Since the teeth 154 of the restraining member 150 radially coupled to the rotating member 140 are engaged with the ratchet gear 118 of the housing 110, the handle cover 170 rotates only in one direction do.

When the teeth 154 of the restraining member 150 radially coupled to the rotary member 140 during rotation of the handle cover 170 move while rotating along the ratchet gear 118 of the housing 110, The ratchet gear 118 is rotated downward until it reaches the top of the inclined surface of the ratchet gear 118. When the rotating member 140 is rotated downward and upward, Is rotated by an angle corresponding to the tooth length of the tooth.

Each of the elastic protrusions 146b formed in the engaging member engaging groove 146 is engaged with the engaging member 150 by the elastic force of the ratchet gear 118 ) At the lowest point of the inclined plane.

The wire W fixed to the first and second wire fixing holes 124a and 124b is inserted into the guide holes 116a and 116b of the housing 110 while the spool 120 is rotated by the rotary member 140. Then, And the object is tightened.

When the user lifts the handle cover 170 upward while lifting the handle cover 170, the rotating member 140 is lifted and the rotating member 140 is lifted up, 2 binding teeth 142 are separated from the first binding teeth 122 formed on the upper surface of the spool 120. [

At this time, the rotating member 140 rotates freely while the binding hole 144 of the rotating member 140 is positioned above the protrusion 132 of the connecting shaft 130.

Since the spool 120 is freely rotatable while the rotating member 140 is separated from the spool 120, the wound wire W can be loosened and the tightening force of the object is released.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible.
