Description

{SHOE'S ROPE LENGTH CONTROLLING APPARATUS}

More particularly, the present invention relates to a shoelace string length adjusting device, and more particularly, to a shoelace string length adjusting device which is capable of easily releasing winding when a shoelace is wound with a finger or a ballpoint pen, And a shoelace string length adjusting device which is formed so as to protrude upwards and is simple and convenient to operate.

As is well known, the recent increase in outdoor hobbies such as mountain climbing, tennis, ping pong, and camping has led to the rapid growth of the sporting goods market including outdoor, and the functionality of personal items such as clothes and shoes has been greatly improved.

In other words, active technological development is being carried out in tight competition.

Typical functions for personal items such as clothing and shoes include user convenience and material specificity such as waterproofing and ventilation.

One of the products that has improved the convenience according to this trend is a shoelace adjustment device which can easily tie and loosen the shoelace.

Patent No. 10-929587 is also a device for adjusting the length of a line, which can more easily take up a line and more easily untie a line.

The rotary housing 120 is coupled to a fixed housing 110 having first and second toothed teeth 113 and 114 formed thereon at an upper portion thereof. When the rotary housing 120 is pushed downward against the fixed housing 110 by configuring the latch 121 to be engaged with the toothed teeth 113 and 114, the latch 121 is coupled to the second toothed tooth 114, The rotation of the rotor 120 is performed in one direction so that the rope is wound around the outer circumferential edge of the rotary housing 120.

If the string is a shoestring, it will have the effect of tightening the shoestring.

In this state, if the user wishes to loosen the string, the user grasps the rotary housing 120 with at least three fingers and lifts it upward. Then, the latch 121 of the rotary housing 120 moves away from the second toothed tooth 114 and is coupled to the first toothed tooth 113.

At this time, since the first toot tooth 113 can not hold the latch 121, if the operator does not grip the rotary housing 120, the rotary housing 120 is automatically released by the elasticity of the string .

The above-mentioned prior art clearly has a part that improves user's convenience.

However, the above-mentioned prior art has some problems.

First, the conventional technique has a problem in that it is difficult to operate with one finger or two fingers because the rotation housing 120 needs to be gripped by at least three fingers in order to unroll the line wound on the rotation housing 120 there was.

Secondly, since the rotary housing 120 has a very small volume, gripping and manipulation are not easy. In particular, it is more difficult to operate the glove in a state in which it is worn by a hand.

Thirdly, the structure of the prior art is such that, in a state where the four latches 121 of the rotary housing 120 and the plurality of second tooth teeth 114 of the fixed housing 110 are engaged with each other, The latch 121 engaged with the first toothed tooth 114 has a hook structure that surrounds the outer circumferential surface of the second tooth tooth 114 so that the contact area is wide so that when the user lifts the rotary housing 120 upward, 121 and the second tooth teeth 114 are not tightly separated from each other.

That is, the latch 121 is strongly urged against the second toothed tooth 114 only when the rotating housing 120 is turned and then the hand is released. Thus, There is a problem in that it is difficult and difficult for the latch 121 to be separated from the second tooth tooth 114 when the winding is released.

Fourth, according to the prior art, the winding of the string is lifted by lifting the rotary housing 120 with respect to the fixed housing 110, and then, when the string is to be wound again, It can easily be forgotten that the housing 120 is lifted and the rotating housing 120 is turned, and it is first found that the string is not wound around the rotating housing 120,

That is, there has been a problem that it is cumbersome to store the string, or a troublesome operation of pushing the rotary housing 120 back to the fixed housing 110 side is required.

Fig. 4 is a cross- And the elevation guide portion.

The shoelace string length adjusting device 2 according to an embodiment of the present invention can be easily released when the shoelace is wound with a finger or a ballpoint pen, Even if the total volume is very small, the pressurizing portion is formed so as to be convex upward so that it is simple and convenient to operate.

The shoelace string length adjusting device 2 according to the embodiment of the present invention is an apparatus for easily tightening or loosening the shoelace strap 1 passing through a plurality of strap guides formed on the shoe, The shoelace 1 can be wound inside the regulating device 2 and the wound shoelace 1 wound out can be released out of the device.

More specifically, the shoelace length adjusting device 2 according to the embodiment of the present invention is formed into a cylindrical shape having a space therein, a toothed tooth 24 is formed circularly along the inner periphery of the upper end thereof, and is rotated in one direction A winding housing (20) having a shoe string (1) wound on a lower outer periphery winding section (32); A rotation guide portion 44 is formed inside a body 42 in which a lower portion of the winding housing 20 is recessed and rotatable and an elevation guide portion A lower housing 40 in which a flow groove 52 is formed at the center of the bottom surface; A fixing protrusion 10 selectively engaging with the tooth 24 is formed at the upper end of the body 6 and a fixing protrusion 10 is formed at the lower end of the fixing protrusion 10. [ And an operating rod 4 to which a flow end portion 14 coupled to the flow groove 52 is protruded and a spring 16 to which an elastic restoring force is normally applied upward is always attached to the outer peripheral edge of the flow end portion 14 .

The lower housing 40 and the winding housing 20 are formed with through holes 50 through which the shoelace 1 passes so as to penetrate the body in the radial direction so that when the winding housing 20 rotates, So that the shoelace 1 can be wound around the shoe naturally.

The shoelace 1 is inserted into the lower housing 30 and the winding housing 20 through the through hole 50 in a state in which the lower end of the winding housing 20 is partially accommodated in the lower housing 40. [ The shoe strap 1 is tightly wound around the outer circumferential edge of the winding housing 20 and wound up when the winding housing 20 is rotated. Thereby, the outer shoe strap 1 is pulled into the lower housing 40.

At this time, the winding housing 20 is covered with the friction member 26 on the outer periphery of the body 22 which is exposed upward, so that the user can easily grasp when gripping and not slip when rotating.

The winding housing 20 is provided with an upper jaw 28 and a lower jaw 28 so as not to be separated from the outer periphery of the upper end of the winding portion 32 and the outer peripheral edge of the lower end of the winding portion 32, (30) is formed.

The lower housing 40 is provided with a lifting and lowering guide portion 46 for lifting and lowering the operating rod 4 without interfering with the rotary housing 20, Is formed with a first protrusion 48 whose upper end is bent toward the center of the interior of the body 6 and which is engaged with the first protrusion 48 of the main body 6 of the operating rod 4, The second jaw 12 protruding in the direction of the second jaw 12 is formed.

Therefore, even if the operating rod 4 moves upward through the restoring force of the spring 16, the elevating guide portion 46 is not released.

In addition, the lower housing 40 has an engagement protrusion 45 whose upper end is bent inward, so that the winding housing 20 can be prevented from deviating freely.

On the other hand, on the outer peripheral edge of the lower end of the winding housing 20 is formed a winding section 32 in which the shoelace 1 is wound. The winding housing 20 is rotated to wind the shoe strap 1 The elasticity of the shoelace 1 with respect to the lower housing 40 is generated and a restoring force to restore the winding housing 20 to its original position is generated.

And the restricting force of the winding housing 20 is suppressed.

The fixing protrusion 10 is brought into close contact with the tooth 24 of the winding housing 20 to control the rotation of the winding housing 20 so that the tooth 24 can rotate only in one direction.

3, when the winding housing 20 is rotated in a predetermined direction, the fixing protrusion 10 rotates while riding over the toothed tooth 24, It is possible to prevent the tooth tooth 24 from rotating in the reverse direction by eliminating the rotational force on the winding housing 20 without interfering with the rotation.

When the shoe strap 1 is to be loosened while wearing the shoe with the shoelace length adjusting device 2 according to the embodiment of the present invention, the shoelace 1 is pulled from the outer circumference of the reel housing 20 It is not all loose, but you can take off your shoes or loosen it loosely enough to wear it again.

In contrast to the case where the shoelace 1 is loosened, when the shoelace 1 is tightened, the shoelace 1 must be securely tightened so that it can not be loosened freely.

At this time, since the operation rod 4 needs to be raised and lowered only irrespective of the rotation of the winding housing 20, the body 6 is formed as a quadrangular column, and the elevation guide portion 46 also has a rectangular tube shape.

The operating rod 4 is provided at its upper end with a pressing portion 8 for pressing the user. The pressing portion 8 protrudes upward convexly to facilitate the pressing.

That is, the shoelace string length adjusting device 2 according to an embodiment of the present invention is configured such that the shoelace string length adjusting device 2 is engaged with the toothed tooth 24 so as to maintain the wound state of the shoelace 1 when the winding housing 20 rotates The fixing protrusion 10 is formed at the upper end of the operating rod 4 and the operating rod 4 always maintains a state of protruding upward by the restoring elastic force of the spring 16 at all times.

Therefore, regardless of whether the user removes the rotational force on the winding housing 20, the toothed tooth 24 is kept in a state in which the rotation of the toothed tooth 24 can not be reversed by the fixing protrusion 10.

The function and operation of the shoelace length adjusting device according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 5A and 5B are diagrams illustrating an operation state of a shoelace length adjusting device according to an embodiment of the present invention.

3 shows a state in which the lower end of the winding housing 20 is assembled in the lower housing 40 and the operation rod 4 is assembled in the center of the lower housing 40 The fixing protrusion 10 is in close contact with the outer circumferential edge of the toothed tooth 24 as shown in FIG.

That is, the operating rod 4 is raised to the inner upper end of the winding housing 30 by the restoring elastic force of the spring 16, and the fixing protrusions 10 Are in close contact with each other.

In this state, in order to tighten the shoelace 1 by wearing the shoe, the user must rotate the friction member 12 on the outer peripheral edge of the upper end of the winding housing 20 in the clockwise direction while holding it.

When the winding housing 20 rotates clockwise, the operating rod 4 is raised to the inner upper end of the winding housing 30 by the restoring elastic force of the spring 16, as shown in FIG. 3 Since the fixing protrusion 10 is in close contact with the outer peripheral edge of the toothed tooth 24 so that the fixing protrusion 10 does not interfere with the rotation while riding over the toothed tooth 24, The shoelace 1 is wound around the winding portion 32. [

At this time, when the user removes the rotational force applied to the winding housing 20 and removes the user's gripping force on the friction member 12, the shoelace 1 wound on the winding housing 20 is elastically deformed It tries to rotate to be restored to its original position. That is, an attempt is made to rotate counterclockwise.

However, since the fixing protrusion 10 is in close contact with the inner circumferential edge of the toothed tooth 24 and the reverse rotation is prevented, the winding housing 20 is rotated counterclockwise . That is, the shoelace 1 is only tightly fastened.

In this state, when the time for the user to release the shoe comes, the user performs an operation of releasing the winding of the shoelace 1.

That is, the user presses the upper pressing portion 8 of the operating rod 4 with his / her finger as shown in Fig. 5B.

The spring 16 provided at the lower end of the operating rod 4 is compressed and the flow end portion 14 formed at the lower end of the operating rod 4 flows into the flow groove 52.

5b, the winding housing 20 is brought into contact with the elasticity of the shoelace 1, and the contact of the fixing protrusion 10 tightly contacted with the inner circumferential edge of the toothed tooth 24 is released, Thereby rotating in the counterclockwise direction.

At the same time, the shoelace 1 is released from the winding portion 32 of the winding housing 20.

As described above, the shoelace string 1 is unwound because all of the shoe straps 1 wound around the winding housing 20 are not pulled apart, but only loosely to the side where the user can put his foot on the shoe You can solve it.

The shoelace string length adjusting device 2 according to the embodiment of the present invention is simple in construction and easy in winding and uncoiling operations and requires no additional operation to make it possible to wind the shoe in addition to the turning operation when the shoe is put on, Relatively less force is required for operation.

In addition, it is very convenient to automatically release the winding on the shoelace 1 if only one finger or one point of the ballpoint pen is pressed.

Meanwhile, the shoelace length adjusting device according to the embodiment of the present invention is not limited to the above-described embodiments, but can be modified in various ways within the scope of the present invention.
