[specific embodiment]

For convenience of description, following embodiment, components identical is represented with identical label.

As Fig. 2 and shown in Figure 4, the preferred embodiment of the utility model fastener, be to be installed on the shoes 300, and can be located on these shoes 300 and the rope band element 200 that is the ran shape reaches and fastens the location purpose for two, the aforementioned rope band element 200 of present embodiment is the shoestring that two lace hole sheets 310 from these shoes 300 pass, and respectively has an end, location 210 and that levels off to shoes 300 and be the terminal part 220 of opposite setting with this end, location 210.Define these shoes 300 and have a center line L between lace hole sheet 310.This fastener 100 comprises a body 10 and and is attached at the unit 20 of pulling that draws on this body 10.Fastener 100 in Fig. 4 is near the true ratio, and all the other each figure amplify the ratio of this fastener 100 to draw, so that understand, and Fig. 3 of following explanation, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9 are also identical.Again, though following examples are to use to be installed on shoes, dress ornament, knapsack, cap such as ... but or other need utilize the article of rope band element bondage to be the application category of the utility model fastener.

This body 10 has a pair of articulated part 11 and two that should center line L and is hubbed on along a length direction X perpendicular to this center line L respectively and fastens unit 12 on this articulated part 11.

This articulated part 11 is en plaque, and has two and be divided into two sides and the pivot ear 111 and two be hollow tubular of curling is located at perforation 112 between the aforementioned pivot ear 111.Pivot ear 111 is to extend along the short direction Y perpendicular to this length direction X to be provided with.

Aforementionedly fasten framework 13 and that unit 12 respectively has a rectangular ring frame shape and be installed in clipping part 14 on this framework 13.Aforementioned framework 13 has respectively that two guide sliding parts 131 and that extend along this length direction X are engaged between the guide sliding part 131 and away from the closed side section 132 of this center line L, its grade is around a perforation 133, and guide sliding part 131 respectively has a pivot joint end 134 and one and the swing end 135 that joins of this closed side section 132 that is articulated in the pivot ear 111.Aforementioned clipping part 14 is to be to be set in slidably on the framework 13, and respectively has two the sliding sleeve portions 141 and on the guide sliding part 131 of being set in and be engaged on depression bar portion 142 between the aforementioned sliding sleeve portion 141.And borrow depression bar portion 142 perforation 133 can be separated into the pass portion 133 of the portion 133 ' that penetrates and between depression bar portion 142 and closed side section 132 of a convergence center line L "; rope band element 200 can from top to bottom pass portion 133 again by after penetrating portion 133 ' up and walk around depression bar portion 142 down ".

This draws the unit 20 of pulling to have a pars intermedia 21 that is the ball-joint shape, two to extend and link the antilift wire 24 that clasp 23 that all-in-one-pieces draw the portion of pulling 22, two directly to be located in to draw in the portion of pulling 22 and two is extended by these pars intermedia 21 bottoms with pars intermedia 21 along this length direction X.This pars intermedia 21 is that the perforation 112 and the bondage bundle that utilize antilift wire 24 to pass this articulated part 11 are tied and be fixed on this articulated part 11, and the aforementioned portion of pulling 22 of drawing utilizes clasp 23 sheathed being attached on the framework 13.

As shown in Figure 3, Figure 4, when desire is installed in this fastener 100 on these shoes 300, the user can be with rope band element 200 by penetrating portion 133 ' down up, and after walking around depression bar portion 142, from top to bottom pass portion 133 again ", and make terminal part 220 just between depression bar portion 142 and closed side section 132.And utilize the terminal part 220 that draws pull unit 20 and rope band element 200 can produce the outward appearance of a bowknot.

Fig. 3 for another example, Fig. 4 and shown in Figure 5, when user's foot is inserted in shoes 300 inside and draws the terminal part 220 of the rope band element 200 of pulling to move towards the direction that is away from center line L, up to foot sensation to suitable tightness and when discharging the application of force to terminal part 220, utilize supporting of foot can make end 210, location possess sizable tension force, and this tension force can drive the depression bar portion 142 of clipping part 14 towards moving away from the direction generation of center line L and terminal part 220 being produced compacting, and make terminal part 220 by depression bar portion 142 and closed side section 132 clipping tightly, just can make rope band element 200 reach the purpose of reverse non-return.

As shown in Figure 6, when user's application of force and with this draw pull single 20 draw the portion of pulling 22 upwards to mention the time, can affect and fasten unit 12 is the center of rotation turn that makes progress with pivot ear 111, and, clipping part 14 acts on because being subjected to locating the tension force of end 210, just can with respect to closed side section 132 produce relatively away from action, that is to say, clipping part 14 can move towards center line L direction along guide sliding part 131 simultaneously, just can make depression bar portion 142 away from closed side section 132, and remove press power to terminal part 220, rope band element 200 can produce and get loose, and impels rope band element 200 by the portion of passing 133 " move towards penetrating portion 133 ', fasten purpose to reach to remove.

Therefore, when the utility model is fastened in 200 releasings of 100 pairs of rope band elements of operation fastener, but only need upwards spur this draws the unit 20 of pulling to fasten unit 12 with regard to interlock, and causing 14 pairs of rope band elements of clipping part 200 to be removed fastens, and articulated part 11 mainly provides framework 13 and articulates and supply this to draw pars intermedia 21 bondages of the unit 20 of pulling to fix, so do not need to make bigger volume, and framework 13 is made the hollow ring frame shape, clipping part 14 is subjected to drawing portion of pulling 22 and rope band element 200 to cover, make framework 13, the concealment effect of clipping part 14 is good, and bulk shape is quite attractive in appearance, lightly.

In addition, as Fig. 7, shown in Figure 8, the body 10 ' of the utility model second embodiment fastener 100 ' only utilize this articulated part 11 ' center line L wherein one of side collocation fasten unit 12 ', and this articulated part 11 ' has a pivot ear 111 ', two perforations 112 ' and are located at the circular hole 113 ' between the perforation 112 ', this clipping part 14 ' is to be cylindric, and has two slide openings 144 ' that wear for the guide sliding part 131 ' of these frameworks 13 '.This draws the unit 20 ' of pulling is to utilize one to be attached on the shoes 300 with the affixed fixedly rope band element 400 of this pars intermedia 21 ', wherein one draw the portion of pulling 22 ' directly to run through binding for this framework 13 ' of fastening unit 12 ', another movable rope band element 200 ' is then still fastened unit 12 ' around passing this, this activity rope band element 200 ' is reached fasten purpose.As shown in Figure 9, when this that upwards spurs corresponding movable rope band element 200 ' draw the unit 20 ' of pulling draw the portion of pulling 22 ' time, can reach one-sided operation and fasten purpose with releasing.
