Description

Shoelace Fasteners {The device for tightenning up a shoelace}

The present invention relates to a fastener for tightening a shoelace, and more particularly, the last shoelace hole on both sides of the upper portion of the tongue brace reinforcement attached to the upper surface of the tongue of the upper shoe that is in contact with the foot It relates to a shoelace tightening machine that can be pulled and wound on both ends of the shoelace passed through.

Shoes are one of the most necessary things in people's daily lives, but there are many kinds of shoes, but most shoes are provided with shoelaces for tightening shoes regardless of the purpose.

Of course, shoes should be selected in a suitable size so that they do not come off while walking, and it is common to wear shoes with the shoelaces slightly loosened to be suitable for taking off and wearing. Tightening the straps to fit inside is known to be good for the health of the feet.

However, it is very cumbersome to loosen or tighten the shoelaces every time you wear them, so it is not uncommon to wear shoes while keeping them properly tied, except in special cases, but the shoelaces are often loosened during normal walking. It may cause bother to be tied again, and even when it is not released, both ends of the shoelace may not be fixed, which may give a sense of neatness, and even more so if the shoelace is long.

Moreover, in the case of young children and the elderly who are in elementary school lower grades or before elementary school, the shoelaces are not easy to tighten, and in particular, for athletes or people who are exercising, such as mountain climbing and racing, Loosening of shoelaces should be absolutely prevented because swelling or knots may be undesirably caused by violent movements or being caught by external objects.

In addition, during breaks during exercise, the tightly-tied shoelaces must be easy to relax, and most preferably, the shoelaces can be easily tightened. Must be present

In order to facilitate the fastening and loosening of the conflicting shoelaces as described above, mechanisms for easily tightening the shoelaces have been developed, and Korean Utility Model Publication No. 1998-069037 discloses shoelace through holes and through holes. It is disclosed that the plate is formed with a "T" -shaped wall and the engaging projection, but the device is a structure for fixing the shoelace through the shoelace through the through-hole and through-hole and the locking projection, the tightened shoelace is easily released But it should not be easy for children and the elderly to use because it must be tightened through the through grooves, through holes and the locking projections that are in close contact with the shoelaces.

In addition, although the lever type device is disclosed in 1999-0002342, this device has a disadvantage that the tightening length is short because the tightening amount is possible only within the rotation distance of the lever.

In addition, Utility Model Registration No. 213470 filed by the present applicant discloses a shoelace reel using a ratchet wheel, but the shoelace reel has a structure in which four ends of the shoelace coming from four directions are wound together on the outer peripheral surface of a specific part of the rotation shaft. As two of the four ends of the shoelace are bent at about 90 ° in the case and then wound on the rotating shaft, the progress is not smooth.The four ends are rolled up together in one place, so the unwinding process is not smooth. There is a disadvantage that the volume of the shoelaces becomes larger in size.

The present invention has been devised to solve all the problems of the conventional shoelace tightening device, not only can easily tighten and loosen the shoelace in appearance, but also to provide a shoelace tightener that can minimize the size of the present invention There is a purpose.

In addition, the lower inner diameter of the housing 11B constituting the main body 11 is smaller than the inner diameter of the ratchet gear portion R that is the upper portion of the housing, but the outer diameter thereof is larger in structure than the lower ratchet gear portion. The inner and outer circumferential surfaces of the lower and ratchet gears are each provided with a stepped portion J. The inner stepped portion supports the bottom edge of the main rotor which is rotated by being seated on the inner diameter portion of the ratcheted gear. The inner circumferential surface to the outer circumferential surface of the part is to support the bottom surface of the rotating cap rotatably coupled.

In addition, in order to stably mount the first and second springs (s) 13C interposed between the two stoppers and between the main rotor and the auxiliary rotor, a spring mounting groove ( It is preferable to have G _S ).

In the shoelace tightening machine of the present invention configured as described above, the auxiliary rotor 13, the rotating member 14, the pressing member 15, the rotating cap 16 and the pressing member guide 17, the writing The tip of the ballpoint pen tip that comes out of the ink comes out from the inside of the ballpoint pen case, or implements a one-touch push-type ballpoint nib operation mechanism that enters from the outside to the inside.

That is, when the upper end of the pressing member 15 protruding to the center portion of the rotating cap upper plate 16A is pressed, the upper and lower portions of the rotating member are in close contact with the mountain portion of the lower surface of the pressing member formed with a hill and a valley in a wave shape. The rotary protrusion E ₄ slides in one direction and rotates while moving on the bottom surface of the rotary guide protrusion E ₆ of the pressing member guide.

In addition, six sliding grooves G ₄ are formed between the rotation guide protrusions E ₆ protruding in the up and down direction on the inner circumferential surface of the pressing member guide, where the shankdong protrusion E ₅ of the pressing member slides. Depth every other one, three deep, three low, regardless of the depth of the pressing member (E ₅ ) of the shankdong protrusion (E ₅ ) can slide up and down along the sliding groove (G ₄ ), but the rotating member The up and down rotation projections (E ₄ ) of the six sliding grooves (G ₄ ) of the three deep sliding grooves (G ₄ ') through the sliding only in the up and down direction, the other three relatively low sliding sliding depth In the groove G ₄ ″, it is caught in the lower end of the groove and cannot move upward.

Therefore, when the rotary member rotates by 60 ° by pressing the pressing member, the up and down rotation protrusion E ₄ of the rotating member moves upward along the deep sliding groove G ₄ ′, but the lower sliding groove is next time. It is caught in the lower end of the (G ₄ ″) and cannot move upward, so that the lowered state is maintained.

The separation distance between the auxiliary rotor 13 and the main rotor 12 in which the upper surface is in close contact with the lower surface of the rotating member 14 is changed by the elastic mechanism of the operation mechanism and the second spring 13C as described above. This determines the operating state of the stopper fluidly coupled to the upper surface of the main rotor.

That is, by pressing the pressing member to the upper and lower rotary projection (E ₄ ) of the rotary member to the lower end of the sliding groove (G ₄ ") of the lower pressing member guide, the upper surface of the rotating plate (13A) on the bottom of the rotating cap upper plate (16A) The close auxiliary rotor is separated from the rotating cap and moves toward the fixed main rotor side, and the stopper operation protrusion E ₁ protruding from the bottom of the rotating plate 13A of the auxiliary rotor is moved to the operating hole H ₃ of the stopper. Is inserted deeply.

Then, as the stopper operation protrusion E ₁ deeply enters into the operation hole H ₃ , the stopper coupled to the upper surface of the main rotor is moved from the edge of the main rotor to the center side, so that the inner peripheral surface teeth of the ratchet gear part T are inclined. The outer end of the combined stopper is separated so that the main rotor can be reversed.

In order to operate the stopper as described above, the upper surface S _U of the inner surface of the main rotor center side is formed as an inclined surface among the inner surfaces of the operating hole H ₃ of the stopper, and protrudes from the bottom surface of the rotating plate 14A of the auxiliary rotor. It is preferable to make the lower end surface S _D of the stopper actuating protrusion E ₁ into an inclined surface that is joined to the upper surface S _U of the inner surface of the main rotor.

At this time, the front and rear operating distance of the stopper and the up and down movement amount of the stopper operation projection can be adjusted by the inclination of the two inclined surfaces, the lower end of the stopper operation projection is always at the upper end of the operation hole (H ₃ ) of the stopper It may be in an inserted state, or may be in an off state. In order to reliably transmit the rotational force of the auxiliary rotor to the main rotor, the rotation protrusion E ₂ having a length longer than that of the stopper operation projection may be replaced by the auxiliary rotor rotor plate ( Protruding to the bottom surface of 13A) to be always inserted into the locking groove (G ₂ ) of the main rotor is a more reliable rotational force transmission structure.

Looking at the use of the present invention shoelace tightening machine of the above structure as follows.

When the upper portion of the pressing member 15 is rotated in a state where the upper portion of the upper surface of the rotating cap upper plate 16A is maximally rotated, the locking protrusion E ₃ is inserted into the locking protrusion groove G ₃ of the lower surface of the rotating cap upper plate. Locking groove G ₂ into which the auxiliary rotor 13 in close contact with the bottom surface of the top of the rotating cap by the elastic force of the second spring 13C and the rotation protrusion E ₂ of the bottom of the auxiliary rotor 13 are inserted in the closed state. ) Is provided with the main rotor 12 rotates together.

At this time, the outer end of the stopper coupled to the upper surface of the main rotor is caught in the teeth (T) of the inner peripheral surface of the ratchet gear (R) as the main rotor can rotate only in one direction, the reverse rotation is impossible.

As the main rotor rotates in the inner diameter of the ratchet gear unit as described above, the shoelace is wound around the outer circumferential surface of the shoelace winding rod formed by protruding from the bottom of the main rotor to the upper surface of the base plate 11A inside the lower housing. You lose.

When the upper surface of the pressing member is pressed to reduce the protruding degree, the upper part of the deep sliding groove G ₄ ′ formed in the pressing member guide 17 in a state of being in close contact with the wave bottom surface of the pressing member. The rotary member 14, which was located at the lower side along the sliding groove G ₄ 'of the pressing member guide, moves to one side by the wave-shaped bottom surface of the pressing member, and the rotation guide protrusion E ₆ of the pressing member guide. Rotating along the bottom surface is held down to the lower end of the sliding groove (G ₄ ") of the lower depth pressing member guide.

As the rotating member is maintained in the lowered state by the operation as described above, the auxiliary rotor, which is in close contact with the rotating cap, is also lowered, and the stopper operation protrusion E ₁ of the auxiliary rotor is lowered to stop the stopper S. As a result, the stopper is separated from the teeth of the ratchet gear portion, and the stopper is separated from the teeth of the ratchet gear portion so that the main rotor and the auxiliary rotor can be reversely rotated irrespective of the rotation cap, so that the shoelace can be released.

As described above, the shoelace tightening machine of the present invention minimizes the size because all means such as the main rotor to which the shoelace is wound and a stopper to prevent reverse rotation are coupled to the inner diameter of the cylindrical lower cylinder and the rotating cap. It is good for aesthetics of shoes, and the stopper that prevents the reverse rotation of the rotor is operated by a one-touch pressing method such as a ballpoint pen, so that the tightening and loosening of the shoelace can be easily used by anyone.
