Abstract

The invention discloses a kind of locking buckle.It can help to wear the people of sport footwear, sneakers, leather shoes or the like frenulum footwear, thoroughly eradicates the shoestring phenomenon that gets loose.It is by hoop knot hole, eyelet, with the perverse lock ligament of number symmetry shape, and advance perverse hole and the perverse hole of lock and front end, the rear end is formed.

Description

Locking buckle

The invention belongs to daily necessities.A kind ofly can effectively prevent the locking buckle that shoestring gets loose.People use sport footwear, sneakers, leather shoes of frenulum or the like.No matter that class lace loop after the knotting, is being worn some times, and this shoestring is easy to get loose.Increase trouble to people, easily cause the accident because of carelessness.

The present invention can overcome above-mentioned shortcoming, uses it can effectively prevent the phenomenon that gets loose of shoestring.

Task of the present invention is finished as follows:

A thing made from the sheet type plastics.By core one bigger elongated hole is arranged, claim hoop knot hole, respectively there is a hole that garden shape is less on its both sides, make eyelet that shoestring is passed, and by the rear end " protruding " font hole are arranged, its broad be into acanthopore, narrower part is locking acanthopore.The other end is a narrower lock ligament, its both sides, and symmetry is with " thorn " shape thing.When (seeing figure (1)) uses, the bottom-up respectively eyelet that penetrates of two shoestrings of will not tie a knot earlier.Locking buckle is moved to be close to the flap face, and make a call to a slip-knot, will lock the ligament bag then to the other end, and front end penetrated the advancing in the acanthopore of " protruding " font, tighten up, at this moment slip-knot has just tightly been waled in hoop knot hole.Because the cause of tension force, the narrower part of the lock ligament of this moment slips into the lock acanthopore automatically.Because the width that advances acanthopore is slightly larger than the width of a pair of thorn, barbed lock ligament is very easy in tightening up, again because lock thorn hole width is slightly less than the width of a pair of thorn.Thorn can not skid off by the lock acanthopore, and barbed like this lock ligament has just been pinned firmly, even anyly cause that the activity of vamp can not make its slippage, has reached the purpose that slip-knot is firmly fastened.

Below with reference to accompanying drawing the present invention is described in further detail.

Figure (1) is a kind of concrete structure plane of the present invention.

Figure (2) is the present invention when using, the schematic diagram of four kinds of states.

With reference to figure (1), the thickness that can be made by plastics or other material is the lock bracelet of 1-1.5 millimeter, there is a bigger oval hole to be hoop knot hole 1, respectively there is a less garden shape perforation 2 on its both sides, form the intermediate host part, and an end has one " protruding " font aperture, the hole of its broad is for advancing acanthopore 3, its narrower Kong Weisuo acanthopore 4, this two hole communicates, and the other end is made up of lock ligament 6.Lock ligament both sides make the width of every pair of thorn outer be slightly less than the into width of acanthopore 3 with several thorns 5 to symmetry.And be slightly larger than the width of lock acanthopore 4, and the front end of lock ligament is a trapezoidal front end 7, it is trapezoidal 8 that the rear end is down,

With reference to figure (two), during use, two shoestrings of will not tie a knot earlier penetrate eyelet 2 respectively from bottom to top, locking buckle are moved to be close to flap face (seeing that accompanying drawing (two) (A)).

Tighten up shoestring and make a call to a slip-knot, (seeing accompanying drawing (two) B).Make front end 7 bag to the back-end 8, and make front end 7 pierce into into acanthopore 3, (seeing accompanying drawing (two) C), tightening lock ligament 6 is because the width of a pair of thorn 5 is slightly less than the width in hole 3, barbed very easy passing through, when receiving very tightly, because the cause of tension force, the narrower part of lock ligament can slip into lock acanthopore 4 automatically, again since the width of a pair of thorn 5 greater than the width of lock acanthopore 4.Therefore, thorn can not be again from the hole 4 retractions.(seeing accompanying drawing (two) D).Like this, the lock ligament just has been lockable.Just the shoestring slip-knot has been fastened firmly by locking buckle.Even taking place, the external force of any upper of a shoe activity also can't make locking buckle loosening.Reached the purpose that prevents that shoestring from getting loose.If will take off one's shoes, as long as make the lock ligament come back to the into position of acanthopore, it just is easy to spread out from the hole, recovers the not state (seeing figure (two) B) of lock.Untie slip-knot again, mention the lock bracelet slightly, shoestring also just pine (seeing figure (two) A), footwear just can unload from foot, lock bracelet and still stay on the footwear, usefulness again when wear next time needn't be taken off.

Because the present invention has adopted single in addition part structure, has all brought convenience for manufacturing and use, design is very exquisite, can give footwear enrichment U.S..

The present invention has eliminated trouble and trouble and worry to using the people of lace loop.

Can reduce the motion accident trauma to the sportsman. And make and concentrate, be beneficial to the best competition state of performance.

Claims

Footwear is characterized in that with locking buckle:

1, the locking buckle of a sheet type made from plastics or other material, it forms mid portion by hoop knot hole 1 and eyelet 2, its end is by lock ligament 6, with front end 7, to form, the lock ligament is to form with several thorns 5 to symmetry shape, its other end is made up of one " protruding " font aperture and rear end 8, " protruding " font aperture is divided into, and advances acanthopore 3 and lock acanthopore 4.

2, the width of its every pair of thorn 5 of the locking buckle of claim 1 regulation is slightly less than the into width of acanthopore 3.But be slightly larger than the width of lock acanthopore 4.

3, the locking buckles of claim 1 or 2 regulations advance acanthopore 3 and lock acanthopore 4, are to be interconnected " protruding " font structure, and, advance acanthopore 3, width be the width that is slightly larger than lock acanthopore 4.
