The wires (cables, strings) currently used in the string tightening system are strings made of nylon fibers or polyethylene fibers, which are very smooth strings with high coefficient of friction and elasticity and high tensile strength. Such a string has a high strength-to-weight ratio, excellent durability, and very low elasticity.

The preferred strings are tightly woven and tightened and woven. The tightly woven string adds stiffness to the finished string. The added stiffness provided while being squeezed and squeezed increases the pressing performance, and the string is easily threaded through the string guide and inserted into the spool, or through the guide to form a loop of string that the user can easily grip.

However, since a separate elastic means is not provided in the string guide of the prior art, the string wound through the string guide and wound on the spool becomes loose as the usage time elapses after being tightened, resulting in a loosening of the tightening force inside the upper of the shoe. Due to the movement of the foot, changes in the volume of the foot, and the impact applied, the upper expands somewhat to the original volume.

In this case, the user perceives that the string cannot maintain the originally tightened pressure. In other words, there was a problem in that the string was released from the reel system, so that the foot inside the shoe would feel looser than the original tightened state.

20 to 21, the spiral cam 50 includes a meshing position portion 51 where the camshaft 32 is located when the winder 30 and the spool 20 are meshed, and the winder When the separation between the 30 and the spool 20, the camshaft 32 is located in the spaced part 52 and the winder 30 between the ratchet 40 is interposed between the shaft in one direction When rotating, the winder 30 and the ratchet 40 are axially rotated to wind the wire, and the spool 20 and the wine are raised by raising the camshaft 32 when the shaft is rotated in the other direction. A disengagement unit 54 is provided to release the engagement of the more 30.

Here, the engagement disengagement part 54 has an inclined surface structure so that the cam shaft 32 can be smoothly moved upward when the lower side of the cam shaft 32 is pressed.

In addition, a lift prevention protrusion 55 is provided above the engagement position portion 51 to prevent the camshaft 32 located at the engagement position portion 51 from being lifted upward during the rotation operation of the dial 60. have.

In addition, when the camshaft 32 is seated, the spaced position portion 52 is smoothly descended from the spaced position portion 52 when it moves to the meshing location portion 51, and is smoothly lowered to slide the meshing location portion ( 51) is formed to be narrower than the width of the cam shaft 32 so as to be accurately guided.

20 to 21, the dial 60 is wrapped around the outer circumferential surface of the spiral cam 50 and is coupled with the housing 10 in a state surrounding the fence 12, and a circular cap rotated forward and backward. It is structured.

Further, the dial 60 has a concave-convex anti-skid protrusion 61 for preventing a finger from slipping when rotating along the outer circumferential surface.

In addition, the anti-slip protrusion 61 is provided with a plurality of finger-hanging protrusions 62 at regular intervals so that a finger is caught during the rotation operation of the dial 60 to stably perform the rotation operation.

On the other hand, the reel system of the present invention is provided with a fastener number 13 in the shape of an upright tubular body on the bottom surface 11 of the housing 10, and the remaining components corresponding to this, the spool 20 and the camshaft 30 , Ratchet (40), spiral cam (50), through-holes are formed in the center of the dial (60), respectively, and through the through-holes of the dial (60), through a separate fastener (70) through which all of them are fastened. (13).

Looking at the operation of the wire tightening reel system of the present invention according to this configuration is as follows.

First, the spool 20 is disposed so that the fastener opening 13 passes through the bottom surface 11 of the housing 10, and the winder 30 and the ratchet 40 are placed in the center of the spiral cam 50. After mounting, the dial 60 is covered with the upper portion, and the winder 30 and the ratchet 40 are combined to be combined with the spiral cam 50 in a state.

Then, after the spiral cam 50 is again connected to the dial 60 connected to the outside of the housing 10, the fastener 70 is fastened to the fastener holder 13 while penetrating the celestial component to assemble it. Complete.

Then, to attach to the shoe, the fixing plate 5 is connected to the bottom surface of the housing 10 to be attached to a desired position of the shoe to wind and unwind the wire through a rotation operation.

Here, looking at the wire winding operation (wire winding mode), while passing through the spaced portion 52 and the upper through portion 41d and being hung on the upper stopper 41a, the upper surface thereof is the ratchet top plate of the ratchet 40 (40a) is in close contact with the bottom surface and the bottom surface is in close contact with the upper surface of the spaced portion 52 and the bottom surface of the upper through portion 41d, the ratchet top plate 40a and the spaced portion 52 (top through portion) (Including the bottom surface of 41d), the tip portion of the camshaft 32, which was firmly engaged and fixed therebetween, is wound around the spiral cam 50 when the dial 60 is rotated clockwise (clockwise). The ratchet 40 and the winder 30 (i.e., the camshaft 32) remain stationary until the 53 reaches the winding surface 43 of the ratchet 40 while the spiral cam 50 ) Is rotated forward (clockwise) while being separated from the spaced apart portion 52, the axis of the ratchet 40 is in a state where the winding projection 53 of the spiral cam 50, which is continuously rotating, abuts the winding surface 43 When the rotation (ratchet 40 of the ratchet 40 elastically passes over the one-way projection 12b of the housing 10 while the ratchet 40 rotates axially), the camshaft 32 is the top stopper 41a After being separated from the ratchet 40, along the inclined surface 41c of the elevating guide 41, descends to the lower engagement position portion 51, so that the axial rotation projection 31 is the winding projection 25 of the lower spool 20 ), and then continuously rotate the ratchet 40 in a state in which the winding projection 53 of the spiral cam 50 is in contact with the winding surface 43, it is engaged with the lower spool 20, and is stationary. The camshaft 32 of the winder 30 in the furnace is moved relative to the engaging position portion 51 below the anti-lifting projection 55 by the ratchet 40 that is axially rotated, and at the same time, the lower end of the ratchet 40. It comes into contact with the stopper 41b.

At this time, the camshaft 32 is prevented from being lifted upward by the anti-lifting protrusion 55, so that the shaft rotation protrusion 31 and the winding protrusion 25 are firmly engaged.

In this state, if the dial 60 is continuously rotated, the winding projection 53 of the spiral cam 50 abuts the winding surface 43, and the camshaft 32 and the lower stopper 41b of the ratchet 40 As a result, the winding protrusion 53 rotates the ratchet 40, the ratchet 40 rotates the winder 30, and the winder 30 rotates the spool 20. Finally, the wire 7 is wound around the winding part 24.

On the other hand, looking at the wire unwinding operation (wire loosening mode), the distal end of the camshaft 32 that hangs on the lower stopper 41b through the engagement position portion 51 and the lower through portion 41e is dialed ( During the reverse rotation (counterclockwise) operation of 60), the ratchet 40 continues to stop in place from when the winding projection 53 of the spiral cam 50 reaches the winding release surface 44 of the ratchet 40. When the ratchet protrusion 42a of the ratchet 40 is stopped by being hung on the one-way protrusion 12b of the housing 10, in this state, if the spiral cam 50 is continuously rotated backward, The camshaft 32, which is the inclined surface structure, is dug into the bottom of the rounded side of the camshaft 32 in the meshing position portion 51, and the camshaft 32 is lifted and the meshing disengagement part 54, which is an inclined surface, is continuously lifted. Ride and move to the upper spaced portion 52, and as a result, the axial rotational projection 31 is disengaged from the lower winding projection 25.

In this way, while the winding projection 53 comes into contact with the winding release surface 44, the reverse rotation of the dial 60 is stopped while the spool 20 is free to rotate, so that the wire 7 is wound on the winding 24. Try to unwind.

In addition, the upper surface of the camshaft 32 is in close contact with the bottom surface of the ratchet top plate 40a of the ratchet 40, and the bottom surface is in close contact with the upper surface of the spaced position portion 52, so as to be spaced apart from the ratchet top plate 40a. It is firmly engaged between the 52 to maintain a fixed state.

Thus, the wire 7 can be wound up and released by a simple forward-reverse rotation operation of the dial 60.

On the other hand, referring to Figure 26 to Figure 28, looking at another embodiment of the sparial cam 50 of the present invention.

Spiral cam 80, which is another embodiment of the present invention, has an elastic cantilever structure with one end connected to the inner circumferential surface between the winding protrusions 83 and the other side protruding to the center in an axial rotation of the spiral cam 80. The elasticity of the ratchet 40 is pushed to the rear by the pressurization of the on-off protrusion 45 and returned to the original state when the spiral cam 80 passes, so that the on-off protrusion of the ratchet 40 is respectively on the front and rear sides of the axial rotation direction ( The tension stopper 86 which elastically supports so that 45) is fixed is provided.

In addition, the tension stopper 86 protrudes back to the center from the distal end protruding to the center, and selectively contacts the winding surface 43 and the winding release surface 44 of the on-off protrusion 45 to connect the ratchet 40. A stopper protrusion 86a for fixing is provided.

Here, the stopper protrusion 86a has a curved surface structure with an outer circumferential surface so that the on-off protrusion 45 can smoothly pass when the shaft rotates.

Looking at the operation process to which the spiral cam 80, which is another embodiment of the wire tightening reel system of the present invention according to this configuration, is as follows.

Here, the rest of the components of the reel system, except for the spiral cam 80, which is the other embodiment, are the same as above.

On the other hand, looking at the wire winding operation (wire winding mode) using the spiral cam 80, through the separation position portion 82 and the upper through portion (41d) and the upper stopper (41a) while hanging on the top surface The ratchet 40 is in close contact with the bottom surface of the ratchet top plate 40a, the bottom surface of which is in close contact with the top surface of the spaced apart portion 82 and the bottom surface of the upper through portion 41d to be spaced apart from the ratchet top plate 40a. It is firmly engaged and fixed between the position portion 82 (including the bottom surface of the upper through portion 41d), and the on-off protrusion 45 is in an off position, that is, the winding-off surface 44 of the on-off protrusion 45 In the state where the end surface 83b of the projection of the take-up protrusion 83 abuts, and at the same time, the winding end 43 of the on-off protrusion 45 and the front end surface of the stopper protrusion 86a are placed in the off position where they abut, and are stably fixed, When the forward end of the cam shaft 32 is rotated (clockwise) of the dial 60, the winding projection 83 of the spiral cam 80 reaches the winding surface 43 of the ratchet 40. The ratchet 40 and the winder 30 (ie, the camshaft 32) are stationary in place, while the spiral cam 80 is rotated forward (clockwise) and deviates from the spaced apart portion 82, The ratchet 40 is axially rotated (the ratchet projection 42a of the ratchet 40 is unidirectional in the housing 10) in a state where the winding projection 83 of the spiral cam 80 which is continuously rotated is in contact with the winding surface 43. When the ratchet 40 is axially rotated while the protrusion 12b is elastically passed over, the camshaft 32 is separated from the upper stopper 41a, and then the inclined surface 41c of the lifting guide 41 of the ratchet 40 is moved. By descending to the lower engagement position 51 along the axial rotation projection 31 is engaged with the winding projection 25 of the lower spool 20, the winding projection 53 of the spiral cam 50 continues When the ratchet 40 is axially rotated in contact with the winding surface 43, the camshaft 32 of the winder 30 which is engaged with the lower spool 20 and is stationary is axially rotated. Relative to the mating position portion 51 below the anti-lifting projection 55 by the ratchet 40 At the same time as it is moved, the ratchet 40 comes into contact with the lower stopper 41b.

Then, while the spiral cam 80 is rotated axially, the tension stopper 86 is pushed rearward by the on-off protrusion 45 and then the tension stopper 86 passes through the on-off protrusion 45, and the tension stopper (86) is returned to the original state again and the on-off protrusion 45 is placed between the protrusion front end surface 83a and the stopper protrusion 86b to be firmly engaged to maintain a fixed state.

At this time, the camshaft 32 is prevented from being lifted upward by the anti-lifting protrusion 85, so that the shaft rotation protrusion 31 and the winding protrusion 25 are firmly engaged.

In this state, if the dial 60 is continuously rotated, the winding projection 83 of the spiral cam 80 comes into contact with the winding surface 43, and the camshaft 32 is engaged with the lower stopper 41b of the ratchet 40. As a result, the winding protrusion 53 rotates the ratchet 40, the ratchet 40 rotates the winder 30, and the winder 30 rotates the spool 20. Finally, the wire 7 is wound around the winding part 24.

On the other hand, looking at the wire unwinding operation (wire release mode), the on-off protrusion 45 is in the on position, that is, the off-winding surface 44 of the on-off protrusion 45 and the rear end surface of the stopper protrusion 86a abut. At the same time, in the state where the winding surface 43 of the on-off protrusion 45 and the projecting end surface 83a of the winding projection 83 are placed in an off position in contact with each other and are stably fixed, the engagement position portion 51 and the lower penetration pass through. When the tip portion of the camshaft 32 penetrating through the portion 41e and hanging on the lower stopper 41b is operated in reverse rotation (counterclockwise) of the dial 60, the ratchet 40 winds up the spiral cam 80 From the time the projection 83 reaches the unwinding surface 44 of the ratchet 40, it stops in place continuously (the ratchet projection 42a of the ratchet 40 is caught by the one-way projection 12b of the housing 10) and stopped State), and in such a state, if the spiral cam 80 is continuously rotated backward, the meshing release part which is an inclined surface structure at the bottom of the rounded side of the camshaft 32 in the meshing position part 81 is rotated. As the 84 is digging, the camshaft 32 is lifted, and then the deceleration portion 84, which is an inclined surface, is continuously moved to the distant position portion 82 above, and as a result, the axial rotational projection 31 is the lower winding projection. The teeth are disengaged with 25.

At this time, when the spiral cam 80 is axially rotated, the tension stopper 86 is pushed backward by the on/off protrusion 45 and then the tension stopper 86 passes the on/off protrusion 45 and the tension stopper passes. (86) is returned to the original state again, and the on-off protrusion 45 is placed between the protruding end face 83b and the stopper protrusion 86b to be firmly engaged to maintain a fixed state.

In this way, while the winding projection 83 comes into contact with the winding release surface 44, the reverse rotation of the dial 60 is stopped while the spool 20 is free to rotate, so that the wire 7 is pulled from the winding 24. Try to unwind.

Thus, the wire 7 can be wound up and released by a simple forward-reverse rotation operation of the dial 60.

The above has been described using the reel system of the present invention, and has only one loop structure in one direction, but it is also possible to have two loop structures in both directions.

As described above, the reel system for fastening the wire of the present invention is such that the spool for winding the wire, the winder engaged and spaced from the spool, the dial for rotating the winder, and the dial to be axially rotated only in one direction that is the wire tightening direction. The ratchet and the spool and the winder are provided with a mesh spacing structure that allows the mesh to be meshed or spaced. By separating the winding of the wire when spaced apart, the winding and unwinding of the wire can be performed only by simple forward and reverse rotation, so that the wire winding operation is basically quick and convenient, and especially for the elderly or children with weak grip, without difficulty As it becomes available, it is possible to promote product competitiveness and reliability.
