Description

Shoelace Fasteners {The device for tightenning up a shoelace}

The present invention relates to a tightening machine for tightening a shoelace, and more specifically, it is attached to the upper surface of the tongue of the upper part of the shoe that is in contact with the foot so that the shoelace can be wound and tightened, Shoelace tightening machine which minimizes the length of the tightening machine by forming the ratchet gear provided on the rotating member to the inner part of the rotating member, and placing the stopper that restrains the ratchet gear on the inner diameter of the ratchet gear. It is about.

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 chosen to be of an appropriate size so that they do not come off while walking, and it is common to wear shoes with the shoelaces slightly loosened so that they are suitable to be taken off and put on. Tightening the shoelaces to fit snugly 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 except for special cases, it is not uncommon to wear shoes while keeping them properly tied, but during normal walking, the shoelaces will loosen and walk. It may cause the hassle of stopping and retying the shoelace, and even if 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 unfavorable results such as record degradation and safety accidents are caused by violent movements or knots caused by violent movement or 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, a number of devices for easily tightening the shoelaces have been developed, and Korean Utility Model Publication No. 1998-069037 discloses shoelace through grooves and penetrations. Disclosed is a plate having a “T” shaped wall with a sphere and a locking projection.

The plate has a structure in which the shoelace is fixed to the shoelace through the through groove, the through hole, and the locking protrusion. The tightened shoelace may not be easily released, but through the through groove, the through hole, the blocking protrusion, etc. that are in close contact with the shoelace. It is not easy for children and the elderly to use because it must be tightened.

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, although the Korean Utility Model Registration No. 213470 filed by the present applicant discloses a shoelace reel using a ratchet wheel, the shoelace reel winds four ends of the shoelace coming from four directions together on the outer circumferential surface of a specific part of the rotation shaft. As a structure, two of the four ends of the shoelaces are bent at about 90 ° in the case and then wound on the rotating shaft, and 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 area becomes larger, the size of the shoelaces reel.

In addition, a shoelace automatic adjustment device using a ratchet gear structure is disclosed in Korean Utility Model Publication No. 232518, which is a shoelace tightening machine using a disc-shaped handle provided with a ratchet gear. Although the convenience is improved compared to the fasteners, the stopper (referred to as "switch" in this design) for restraining the ratchet gear is operated in the forward and rearward direction from the outside of the ratchet gear, so the overall length of the device is increased. If the appearance of the tongue hurts, and the length of the tongue is short, there is a problem that is difficult to attach.

The present invention has been devised to solve all the problems of the conventional shoelace fasteners, the length is minimized to improve aesthetics in the state coupled to the shoe, as well as attachment to short tongues. It is an object of the present invention to provide possible shoelace tighteners.

The object of the present invention is achieved by a ratchet gear having a tooth formed on the inner circumferential surface and a stopper coupled to the inner diameter portion of the ratchet gear.

The shoelace tightening machine of the present invention has a ratchet gear formed at the inner diameter of the rotating member to which the shoelace is wound, and a stopper capable of preventing reverse rotation of the ratchet gear is generally located at the inner diameter thereof. Compared with the structure provided with the stopper on the outside of the gear, the length of the entire tightening machine can be shortened.

The shoelace tightening device of the present invention as described above, the housing is fixedly attached to the upper surface of the shoe tongue, the rotating member rotatably coupled to the housing, the stopper located in the inner diameter of the rotating member, and the inner diameter of the rotating member It consists of a lid sealing the upper end, a coupling shaft connecting the lower housing and the upper stopper after passing through the rotating member, a stopper connecting the upper end of the coupling shaft and the lid, and a spring mounted on the coupling shaft. Instead, a stopper for restraining the ratchet gear having a tooth formed on the inner circumferential surface thereof is formed in the inner diameter of the ratchet gear.

The housing is composed of a disk-shaped bottom plate fixedly attached to the upper surface of the tongue of the shoe by sewing, and a cylindrical sidewall formed upright in the center of the bottom plate and provided with a plurality of shoelace through holes, wherein the cylindrical sidewall is formed by rotating member. Will play a supporting role.

The rotating member has a ratchet gear formed on the inner circumferential surface directly under the top surface, and has an upward open cylindrical rotor having a through hole of a circular cross section at the center of the bottom surface, and is formed vertically downward from the bottom of the rotor and has a plurality of shoelace through holes. It is made of a bobbin, the shoelace is wound around its outer peripheral surface while the shoelace is fixed to the inner diameter of the bobbin.

The inner diameter of the rotor is higher than that of the ratchet gear, and the stepped portion is formed at the upper end of the inner diameter of the rotor by the ratchet gear.

The disc-shaped lid covering the upper end of the rotating member, that is, the upper end of the rotor, is placed on the upper surface of the ratchet gear provided in the inner diameter of the rotor, which is a stepped portion, and a straight through groove is formed from one side edge to the center thereof. The bottom surface adjacent to both ends of the groove in the width direction is a structure in which the straight coupling pieces protrude from the longitudinal direction of the through groove, respectively.

The lid is detachably inserted into both sides of the stopper housing of the upper end of the coupling shaft in a state in which the lid is placed on the upper surface of the ratchet gear formed by the ratchet gear, and the upper surface of the lid is the upper end of the rotor. The height between the upper surface of the rotor and the upper surface of the ratchet gear is equal to the thickness of the lid so that the top surface of the lid and the upper surface of the rotor are not flush. It is desirable to achieve this.

The stopper, which restrains the ratchet gear of the rotating member, includes a head capable of sliding reciprocating in the radial direction of the lid with its flat bottom face in contact with the upper face between the two engaging pieces of the lid, and through the lid from the bottom face of the head. It consists of a bridge extending through the groove to the inner diameter of the rotor, and a locking member provided at the lower end of the bridge to be located on the inner diameter of the rotor, one end of the locking member is provided on the ratchet gear provided on the inner circumferential surface of the rotor. Get bitten.

That is, one side end of the locking member is bitten by the ratchet gear or separated from the ratchet gear as the head moves on the upper surface of the lid, and as a result, reverse rotation of the rotating member is prevented or enabled.

Reverse rotation of the rotating member means rotation in the direction in which the shoelace is released, and forward rotation of the rotating member means rotation in the direction in which the shoelace is wound around the bobbin.

Coupling shaft is fixedly coupled in the state that the bottom surface is in close contact with the center of the bottom surface of the housing and does not rotate, the coupling rod is located in the inner diameter of the rotor after the top end penetrates the rotor, the locking member of the stopper Is formed by an upwardly open stopper housing provided on the upper end surface of the coupling rod so that the sliding member can be slidably reciprocated from the inside and then one end of the engaging member can protrude to the outside. A spring is interposed between the inner side of one side and the other end of the stopper engaging member opposite thereto.

At this time, the engaging member of the stopper is coupled to the center portion in the width direction of the stopper housing, and a pair of coupling pieces protruding downward from the bottom of the lid are inserted into and coupled to both sides thereof.

In addition, the stopper locking member is not coupled downwardly toward the inside through the open upper end of the stopper housing, but is slidably coupled inwardly from one edge portion of the stopper housing, and the locking member of the stopper is stopped. Rather than separating upward through the open upper end of the housing, the structure is separated only by sliding inward toward the edge side.

In addition, the coupling shaft is fixed without rotation, but the rotational force can be transmitted to the coupling shaft in accordance with the rotation of the rotating member, the portion through the rotor in the coupling rod of the coupling shaft to have a circular cross section, the lower end of the polygon than the circular At the same time, the lower end of the coupling rod is inserted into the center of the housing bottom plate to form a polygon groove to be molded, and then the lower end of the coupling rod is inserted into and fixed to the polygon groove to fundamentally prevent rotation of the coupling rod. It is also preferable.

At this time, when the cross section of the lower end of the coupling rod has a circular shape, for example, the lower end of the coupling rod must be fixed with a pair of bolts penetrating the bottom of the housing to prevent rotation of the coupling rod. When the cross section is polygonal and closely inserted into the polygon recess formed in the housing bottom plate, only one bolt may fix the coupling rod so as not to rotate.

The shoelace tightening device of the present invention configured as described above, the bottom surface of the coupling shaft is fixedly coupled to the bottom surface of the housing attached to the shoe tongue so that the coupling shaft does not rotate with the housing, the stopper located at the upper end of the coupling shaft The lid coupled to the stopper seated on the housing and the bottom is inserted into the stopper housing also does not rotate.

However, the rotary member located between the bottom of the lid and the side wall of the housing should be rotatable, so that the height of the upper surface of the ratchet gear inside the housing where the lid is placed is in contact with the bottom of the stopper head seated on the stopper housing of the coupling shaft. It must not be higher than the base height of the.

In other words, if the height of the top surface of the ratchet gear is higher than the bottom of the lid, the bottom of the lid in close contact with the bottom of the stopper head should press the top of the ratchet gear when the coupling shaft coupled with the stopper is tightly coupled to the bottom of the housing. As a result, free rotation of the rotating member is impossible.

As described above, the rotating member is in a rotatable state through a form in which the housing and the rotating member and the lid are sequentially stacked. In this case, the stopper is caught by the elastic force of the spring mounted between the inner surface of the stopper housing and the other end of the locking member. Since the one end of the member is in the state of being bitten by the ratchet gear, the rotating member can only be rotated forward.

Therefore, when the stopper head protruding from the upper surface of the lid is pushed toward the central portion of the lid, one end of the stopper locking member is slidably retracted in the stopper housing at the upper end of the coupling shaft, thereby being separated from the ratchet gear, thereby allowing the rotating member to rotate in reverse. When the force applied to the stopper head is removed, one end of the stopper engaging member returns to its original position by the spring force of the spring, thereby restraining the ratchet gear.
