Specific embodiment

Referring now to disclosed buckle and more specifically with the buckle of belt, Fig. 1 is shown according to the disclosure Adjustable buckle and front view with sub-component 100, show in its normal latched position.As shown in fig. 1, buckle 102 are shown with belt 1, and belt 1 has across the free end of buckle 102 2.According to one embodiment of the disclosure, buckle 102 include single elastic yarn, is bent to form two overlapping rings.Two overlapping rings are by identical due to them Single (i.e. integral type) elastic yarn is constituted and integral with one another.Bending in silk defines four cross members, they are in Fig. 1 Labeled as 3,4,5 and 6.Cross member 3 and 4 constitutes the movable end of buckle together, and cross member 5 and 6 (together) constitutes buckle Partner.

In the embodiment of buckle 102, (after the appearance of cross member 4, which is limited for the free end 7 of silk One section of silk of one section of silk of ring, another ring which is limited by cross member 3 clamps belt together) it is further curved It is bent twice, to form difunctional bar, as shown in figs. 1 and 2.Cross member 3 and 4 defines keyed end.

In the present embodiment, the other end 8 of silk passes through sharp bending section (to incite somebody to action after coming out from cross member 6 Silk locking is in place) or by other permanent or semipermanent means for attachment (such as welding, be brazed, adhesive etc.) and for good and all It is attached to the end of cross member 5, as shown in the embodiment in Figure 11-13 and 15.In the present embodiment, cross member 6 is in function Can on anchoring surface at the Partner as buckle 102；Various hooks and/or other buckles and/or other belts can be attached It is connected on cross member 6, to extend adjustable buckle and the function with sub-component 100.

With reference to Fig. 3, hook-type buckle 9 is attached at the fixing end 10 of belt 1, fixing end 10 is anchored to any (it can be tie down ring or another object to desired and suitable anchor point, or can even be anchored and return to buckle 102 cross member 6 (referring to Figure 10)).In Fig. 3, the fixing end 10 around the belt 1 of hook-type buckle 9 is configured to have Small ring (belt is by folded back on itself and sutures, to be for good and all attached belt and buckle 9).In such configuration, belt 1 can be with The thing (such as one or more objects) that wrapping needs to be tightened with belt 1, and the length of the free end 2 of belt 1 is corresponding Ground is adjusted, to tighten the one or more object.Hook-type buckle 9 can be attached to other fasteners or hook, such as attached It is connected to the hook 11 of article (such as 12).

Similarly, in other embodiments, the Partner (specifically cross member 6) of buckle can be equipped with double hook 13 (as shown in Figure 3) or other hooks are such as anchored to object 14 to realize anchoring function at the Partner；In alternative In case, additional attachment device can be used by cross member 6 and be directly or indirectly connected to any suitable anchor point.

As shown in Figures 5 and 6, at its free end 2, belt 1 is operatively engaged the movable end of buckle, preferably by making The free end 2 of belt 1 is passed through around cross member 3 and 4.In the present embodiment of buckle 102, cross member 3 and 4 is usually straight And it is parallel to each other, but be not located in same plane: cross member 4 is located at flat above the plane occupied by cross member 3 In face (preferably in figs. 5 and 6 shown in visible in side view)；In the case where the relaxation of buckle (is not tensioned) state, lateral structure The distance between part 3 and 4 (gap) (the line A-A of Fig. 5) is preferably approximately equal to be intended to the thickness for the belt being used together with buckle Twice of degree.

Fig. 8 and Fig. 9 shows the embodiment of hook-type buckle 9 comprising single elastic yarn, the silk are bent to form substantially J-shaped hook.Fig. 8 and 9 shows the J-shaped of rotation, so that the bottom of longer " arm " along view.The end 15 and 16 of silk is substantially It is overlapped and is back bent 90 degree towards the other end, with the form the fixing end 10 for fitting through belt first lateral structure Part.Then, the every silk 90-degree bent in orthogonal plane again, to limit even length, corresponding first arm 17 that parallel interval is opened With 18, and every silk is back bent 90 degree again towards the first cross member, is spaced apart with to limit parallel even length Component (only shows component 19).Finally, silk is bent twice again towards the other end, to form the second arm 20 of even length With 21 and cross member 22.Arm 20 and 21 is shorter than arm 17 and 18.(such as pass through it may be preferred that the midpoint of neighbouring silk is formed Bending), be initially formed cross member 22 and so that end 15 and 16 overlapping terminate.The length of spacer member (such as 19) It is enough for hook frame 9 to be hooked on the cross member 6 of buckle 102.

As shown in Fig. 3 and Figure 10, adjustable buckle and it can be used in various ways with sub-component 100.User It can be started by the way that the Partner of buckle to be anchored to the fixing end of the first object or belt；In other embodiments, various Hook and/or other buckles and/or other belts may be used as anchor log.In one example, if being previously not passed through band Son, then user then proceedes to that the free end 2 of belt 1 is passed through and folded around the cross member 3 and 4 (keyed end) of buckle (as shown in the route map described in Figures 5 and 6)；If buckle and belt keep certain relative angle (such as Fig. 6 relative to each other In it is specifically shown as, this be allow belt with it is the smallest rub slide through in both directions buckle ring preferred position Set), then this process can be more easily done.After the free end 2 of belt 1 eventually passed through returning to below cross member 3, The free end 2 of user and then belt 1 of pulling back, with the desired length (or girth) of adjusting belt, and in adjusting belt Power.There are under opposite power on the belt on the other side of keyed end, the tightening force on the belt of free end is at keyed end It clamps belt and locks belt.

Due to its novel structure, allow belt in one direction (that is, tensing the side of belt according to the buckle of the disclosure To) on the smallest Frictional Slipping, this allows to by simply in the free end 2 of direction last time drawstring 1 along belt 1 And it is directed toward far from buckle and belt is tightened into (tension).However, when reaching, desired fastening is horizontal and user stops drawing When dynamic free end 2, buckle locks and belt 1 is not allowed to move in opposite direction；Tension in belt 1 draws cross member 4 To cross member 3, and cross member 3 is pulled to cross member 4 by the tension on cross member 6, to realized automatically by belt 1 Tightly friction grip is between cross member 3 and 4；Any additional tightening force on belt 1 is by further tightening buckle The clamping of belt 1 between interior cross member 3 and 4 and in buckle generate even more robust clamping action.According to this public affairs It opens, the clamping force between cross member 3 and 4 is directly proportional to the tightening force for being applied to belt.When in belt 1, from buckle When the tension at both ends pulls cross member 3 and 4 toward each other, the two cross members, which are always to maintain, to be roughly parallel to each other, Clamping force can be made to be uniformly distributed in band of material in this way, to reduce non-uniform fretting wear.

In order to discharge the tension in belt 1, user is simply lifted along from the plane upwardly direction of cross member 3 Difunctional bar 7 (it is connected to cross member 4 and buckle), thus buckle is positioned to certain angle relative to belt by such movement It spends (as shown in Figure 6), and cross member 4 is made to depart slightly from the movement of cross member 3, to realize to the clamping action of buckle It discharges and belt 1 is allowed to slide along reversed (loosening) direction.

Elastic yarn construction provides the effect of spring-like, so that when bar is by (from the belt) in operation and buckle Tension reduce when, the cross member 3 and 4 of silk move each other it is separate, to restore their relative spacings.

Difunctional bar 7 is also used as security-latch: in buckle locking and the tensioning of belt 1, if user will be double The plug of functional bar 7 (as shown in Figure 2) below belt 1 then realizes the maximum grip of belt 1 between cross member 3 and 4, from And buckle is firmly held under maximum grip construction.In order to which from " security-latch " position release buckle, user must be incited somebody to action Difunctional bar 7 is slightly moved to side, and being then at it, naturally " locking " position (is sitting in the top of belt, such as middle Fig. 1 It is shown).Note: difunctional bar 7 is moved to its naturally " latch " position from " security-latch " position (plug is below belt 1) (above belt) will not discharge the tension in belt 1, but it can only remove additional " safety " function: buckle keeps locking shape State, belt 1 keep being in tensioning state.It is only as user that difunctional bar 7 is enterprising in the plane upwardly direction from belt When one step is lifted, it is just able to achieve release buckle.

According to another embodiment of the present disclosure, in some cases, buckle (as described above) can preferably work (clamping firmer/stronger and once in the lesser meaning of a possibility that fastening then 1 skidding of belt/loosening), if Belt 1 is all kept under a certain amount of tension on all operating times.For this purpose, some embodiments of the present disclosure can Buckle (as described above) and the belt made of the material with certain elastic force (or " extensibility ") to be matched；? The such band period of the day from 11 p.m. to 1 a.m of fastening is buckled in belt and band on all operating times and all keeps a certain amount of tensile.It is replacing For in scheme, unshowned resilient extension (or elastic insertion piece) can be added to other stiff belt (or Even flexible belt), the tensile of similar quantity is obtained in belt on all operating times, so as to cause The clamping function of buckle is improved.Note: even if buckle also can work well in the case where belt is absolutely not elastic Make.

In order to realize " quick release " functionality, it is sometimes preferred to by buckle and belt (as described above) with it is various other existing Have technology hook be used in combination, the hook can be quickly attached to cross member 6 or be attached to belt 1 fixing end 10 or It is disassembled from the fixing end 10 of cross member 6 or belt 1.In this case, user need to only lift difunctional bar 7 Buckle 102 can be unclamped, then this is just easy to unlace completely in the other end, thus realize " quick release " function, It is unlocked completely without buckling the free end 2 of belt 1 from band.That is, the holding of belt 1 is through on buckle 102, still There are enough relaxations to unlock or otherwise free end 10.

Figure 11-13 and 15 shows the second embodiment of the buckle 102A with the feature similar with buckle 102.Figure 14 and 15 The second embodiment of hook-type buckle 9A similar with hook-type buckle 9 is shown, and Figure 13 and 15 shows adjustable buckle and band Sub-component 100A includes being attached to the buckle 102A of hook 9A in Partner.

Buckle 102A and buckle 102 the difference is that, end 8 is usually welded in that section limited by line B-B It is connected on buckle 102A.(the cross member 3 as shown, other pairs of cross member 3 and 4 and 5 and 6 usually partly overlaps With it is 4) or completely overlapped (cross member 5 and 6), wherein cross member 3 and 4 be spaced apart, with accommodate belt 1 free end 2 (figure 13).Cross member 5 and 6 is tightly enough spaced apart, so that they are substantially mutually touched along their own length.This Sample, component 5 and 6 define the Partner of buckle 102A, and may be hooked on hook-type buckle 9A (Figure 15).Also show in Figure 15 The handle portion limited out by belt 1, the handle portion have certain length belt, the belt of the certain length define itself at Ring and the handle portion for being attached to end 10.

Hook-type buckle 9A and hook-type buckle 9 the difference is that, hook-type buckle 9A is defined as arm 17 and 18 than arm 20 It is short with 21.In addition, in hook 9A, end 15 and 16 (in the ring being present at the fixing end 10 of belt 1) abut against one another and It is not overlapping.May exist enough gaps, between end 15 and 16 to allow the ring at fixing end 10 from hook-type It is removed on buckle 9A.If necessary, this, which abuts construction, can permit ring end around the sliding of hook-type buckle, with more easily It is attached on 22 (not shown) of cross member.

The hook-type buckle of such as 9 or 9A etc or other can the use that is connected on belt 1 of quick release provide and be used for Adjustable buckle and quick connection/separation mechanism with sub-component.It should be understood that the fixing end 10 of belt 1 can be At the anchoring surface of Partner, such as around cross member 6 or cross member 5 and 6, it is directly coupled to buckle 102,102A.Anchor Determine surface to provide buckle 102,102A being directly or indirectly coupled to object via cross member 6 or a pair of of cross member 5 and 6 The means of body or belt.

Compared with buckle 102, more closely (lateral) is positioned to least partially overlapped to cross member 3 and 4 each other.In buckle In 102, cross member 3 and 4 is thickness that is nonoverlapping and deviating about 2 times of belts.In this embodiment, cross member 4 exists Here it is oriented than it in the embodiment of buckle 102A closer to cross member 5.That is, cross member 4 is positioned At closer to the centre of buckle 102, to provide the offset of 2 times of band thickness.In the embodiment of buckle 102A, partly overlap Positioning and enough horizontal spacings to allow belt to slide through bigger friction is provided on belt.Due to part weight Folded property, when belt is tightly tightened, which is further narrow as, with more tightly clamp across belt.This In term " lateral " refer to the movable end between the cross member 3 and 4 of movable end and the component 5 and 6 of Partner in buckle The lateral axes extended between Partner.Term " herein laterally " refers to the first ring with cross member 3 and 6 and has Transverse axis between second ring of cross member 4 and 5, orthogonal with the lateral axes.
