Afterbody 46 can be inserted into tapered end 16, is used for band around one or more article locking to be fixed.Tapered end 16 holds Receive the ball 22 for keeping elongate strips 18 and afterbody 46.Afterbody 46 can insert tapered end 16 also in the first direction And kept by the joint of tapered end 16 and ball 22 when moving along the second direction contrary with first direction, thus Afterbody 46 is maintained in tapered end 16.The general structure of band discussed in this article and function are in June, 2000 The commonly assigned patent of entitled " the Cable Tie " that issue for 20th is more fully described below.This patent application is with ginseng The mode seen all is included in herein.

When fastening around one or more article of such as steel bar bundle 14 or steel pipe bundle 12, in order to prevent ball 22 Tapered end 16 moves, is thus also prevented from afterbody and falls back mobile in a second direction and avoid tapered end 16 to unclamp, formed Multiple shaping undulations (as shown in reference 26a, 26b, 26c in Fig. 1 etc.) in belt body 18 It is used to the tie-down strengthening belt body 18 around one or more article 12,14.In various embodiments of the present invention, Shape undulation can amount to just 4,5 (as shown in reference 26a), 6 (such as accompanying drawing Shown in labelling 26b) or 7 (shown in 26c).More or less of shaping undulation is also regarded as at this In the range of invention.Shape undulation 26a, 26b or 26c can be formed near afterbody 46, tapered end 16 Or other position any in elongate strips 18.Band 10 have high-tensile advantage, be lightweight, There is the long life, be simple to manufacture and economical.

In a preferred embodiment, the tapered end 16 of the disclosed invention, belt body 18, ball 22 and other elements all All formed by rustless steel, to allow band to be used for various temperature range, and give band high-tensile and Excellent rotproofness in harsh weather.Such as 304 rustless steels can be used (to be alternatively referred to as A2 rustless steel Or 18/8 rustless steel) or 316 stainless steel.It should be appreciated, however, that band 10 can by such as include aluminum, Other material of pyrite, copper, other types of metals of ferrum or even plastics is configured to.Other configuration can be used, and And be all considered within the scope of the invention.In an embodiment, such as, ball 22 can be with allowing similar locking The substantial cylindrical lock pin engaged substitutes.

First the band 10 of the present invention preferably by obtaining from band volume (not shown) according to the application of band 10 The elongate strips 18 obtaining suitable length is formed.In an embodiment of the present invention, logical in order in many applications By availability, elongate strips 18 has the length between 26 inches and 27 inches.Or, elongate strips 18 Can have 200 millimeters of (" mm "), length of 260mm, 360mm, 520mm or 680mm.Make For another alternate embodiment, elongate strips 18 can have between 190mm and 200mm, at 250mm and Between 270mm, between 350mm and 370mm, between 500mm and 540mm or at 650mm And the length between 700mm.In various embodiments, the width of elongate strips 18 can be 4.6mm, 7.9 Other width of mm or any (or, alternatively, between 4mm and 5mm or between 7mm and 8mm). Manufacture shaping undulation 26a, 26b or 26c that the next step of band 10 is formed in elongate strips 18. In one embodiment, the undulation 26a that is formed in elongate strips 18 with the mould punching in press, 26b, 26c.For manufacturing purpose, for each shaping undulation, it is most useful that shape undulation with other (as shown in reference 85 in Fig. 4) forms 60 degree of angles, or any angle between 55 degree and 65 degree, because of Can being once stamped and formed out with mould for such angle.In order to utilize the disclosed invention, it is possible to use 90 degree Angle (as shown in reference 85 ' in Fig. 5) or any angle between 85 degree and 95 degree, but formed such Undulation may need to make elongate strips 18 by mould punching press more than once.Elongate strips 18 is by principal plane 4a and diametrically opposite secondary plane 4b limit, as Fig. 6 draws.

Then, tapered end 16 is preferably by generally rectangular-shaped general plane metal stock (not shown) shape Become.As shown in Figure 6, preferably make the top 32 of of completely closed domed form first at the central part of metal stock Formed in point.In a preferred embodiment, preferably as it is shown in fig. 7, relative rectangular notch 34a and 34b then wears Cross metal stock to be formed on opposite edges 36a and 36b, in order to when the phase of the blank including notch 34a and 34b Bend part 38a to leave or be folded into together with 38b and below top 32, make notch 34a and 34b and limit When edge 36a and 36b is in direct relativeness, which define tapered end 16 is positioned at bottom below, top 32 40.So, notch 34a and 34b associated are to limit the substantially square hole 42 through bottom 40.The phase of metal stock Region should be bent and limit sidewall 44a and 44b of tapered end 16, and surround top 32 and cover the metal of bottom 40 Green part limits top board 43.Thus, it can be seen that sidewall 44a and 44b makes top board 43 and bottom 40 phase Connect.

Then, by the tourelle of the band 10 of the form preferably by ball 22 through the hole in bottom 40 42 insert tapered end 16.In the case of tapered end 16 is oriented so that ball 22 keeps being suitably located in head 16, head Portion 16 can be slideably mounted on the belt body 18 of afterbody 46 so that bottom 40 is adjacent to second surface 20b. On this position, top 32 and top board 43 cover on the first surface 20a of band 18, it is noted that ball 22 It is fixed on being captured in head 16 by top 32 and band 18.First end 30 of band 18 is in perforation 66 Place folds up, and projection 28 is inserted also breech lock and in one hole 42, thus tapered end 16 is fixed to band 18.

As best illustrated in figs. 6 and 7, tapered end 16 includes band upstream end 50, the band port of export 52 and wears Cross the band that tapered end 16 extends between the ends and receive passage 54, band receive passage 54 partly by top board 43, Sidewall 44a and 44b and bottom 40 limit.Top board 43 can cover with the relation substantially parallel with bottom 40 On bottom 40.Top 32 preferably includes the first and second substantially straight divergent portions 56 and 58 and substantially The convergence portion 60 of arch.First and second divergent portions 56 and 58 and bottom 40 are along the direction of the port of export 52 Diverging from one another.In a preferred embodiment, the second divergent portion 58 has the angle of divergence less than the first divergent portion 56. On the contrary, arcuate section 60 is assembled along the direction of the port of export 52 to each other with bottom 40.The port of export of head 16 The counteracting force face of 52 noses being also used as tradition taut band instrument (not shown).

As shown in Fig. 1-6 and 8-10, undulation 26a, 26b, 26c include that amounting to 4 shapes wavy Volt, 5 26a, 6 26b, 7 26c, 8 or above multiple shaping undulations.It is being preferable to carry out In example, multiple shaping undulation 26a, 26b, 26c can only extend from the principal plane contrary with secondary plane 4b. In alternative embodiments, shape undulation to extend from the principal plane 4a of elongate strips 18 and secondary plane 4b. As shown in Figure 4, in embodiments of the present invention, each shaping undulation can shape undulation formation with other Between 55 degree and 65 degree or the just angle of 60 degree (as shown in 85).In independent embodiment as shown in Figure 5 In, each shaping undulation can and other shape undulation and be formed between 85 degree and 95 degree or just The angle of 90 degree (as Suo Shi 85 ').Note, in fig. 4 it is shown that the element 85 at 60 degree of angles is with reference to 5 shapings Undulation 26a illustrates, and in Figure 5, the element 85 ' of display an angle of 90 degrees shapes wavy also referring to 5 Volt 26a ' illustrates, it is noted, however, that the angle discussed can be with any amount of shaping being formed in elongate strips 18 Undulation is used in combination.Undulation can be adjacent to head or in other local formation.In embodiments of the present invention, All shaping undulations can have the length less than 1 inch.

With reference to Fig. 8-9, such as the tourelle of ball 22 can be from piercing into shown in Fig. 8 in tapered end 16 (threading) position is moved to the latched position shown in Fig. 9 or locked position, is piercing into position, and ball 22 can Being arranged against the arcuate section 60 at the top 32 of the adjacent tapes port of export 52, in latched position, ball 22 wedge leans on Divergent portion 58 at top 32 and closer between the band 18 of band upstream end 50, and then make band 18 Wedge leans on bottom 40, the most generally prevents band 18 from falling back movement from its latched position tapered end 16.Such as this Literary composition is used, and term " wedge " or " wedge leans on " meet its broad sense, simply to represent in its latched position, and ball 22 It is extruded or compacted with band 18.

The operation of band 10 is as follows: after band 18 deforms to wrap up article 12 or article group 14, band The afterbody 46 of body 18 inserts tapered end 16 along the first direction shown in the direction such as arrow A through band upstream end 50. When continuing in the direction of arrow A to pierce into by passage 54, band 18 contacts ball 22, so that it promotes also Move to the position of piercing into shown in Fig. 8.Should be appreciated that owing to ball 22 can be at band 18 during piercing into Upper rolling, therefore piercing into of band has only to the least power.This is by the existing skill of the pierce into power much bigger with needs Art band is completely different, in prior art band, it is necessary to force the dead bolt being biased to its latched position to deflect into It pierces into position.Band 18 is caused along the first direction shown in arrow A through the action of persistently piercing into of passage 54 Leave from tapered end 16 through the band port of export 52.Band 18 be pulled through tapered end 16 until its tightly around Article 12 or bundle of objects 14 are to predeterminated level, as shown in Figure 8.

Tightened position as shown in Figure 9 is drawing due to the afterbody 46 insertion in head 16 and band 18 Tightly produce.As seen in Fig. 3 and 8-9, the tension of band 18 may be used for spring-like Mode make shaping undulation 26a, 26b or 26c extend.By shaping undulation 26a, 26b, 26c quilt The counteracting force applied during stretching for along as shown by arrow B second direction apply sizable power, thus Keep band being engaged by locking around one or more article to be fixed.

With reference to Fig. 9, after band 18 is tightened to predeterminated level, unclamp band 18 and with from shape wavy The power cooperation of volt 26a, 26b or 26c, causes elongate strips 18 and ball 22 along the second direction shown in arrow B to bar Band upstream end 50 moves or retreats until ball 22 simultaneously engages with top 32 and band 18.As shown in FIG. 8 and 9, ball 22 The shortest at its stroke pierced between position and latched position.When ball 22 is in its latched position, ball 22 and top Frictional engagement between portion 32 and between ball 22 and band 18 is typically enough to prevent ball 22 and rolls, thus causes band Wedge leans on bottom 40 tightly.Additionally, it is wavy with the shaping being stretched along the second direction shown in arrow B as mentioned above The power that fluctuating 26a, 26b, 26c are associated can be strengthened preventing ball 22 from rolling further, thus by promoting band 18 Wedge carrys out the strengthening strip 18 locking in head 16 by bottom 40.By shaping undulation 26a, 26b or 26c along arrow The vitality that the direction of head B applies also keeps band 18 around the tie-down of article 12 or 14.When starting to lock, ball 22 Realize the permanent deformation of band 18 also by impression, this impression causes previous stripping below ball 22 actually Become cold flow, form the rim around impression.

Figure 10 shows the alternate embodiment of the present invention being generically designated as reference 10 '.Band 10 ' is substantially As band 10, shaping undulation 26a, 26b or 26c of being simply shown as 26a ', 26b ' or 26c ' are positioned at band Another location on 18, such as outside head 16.In another embodiment, shape undulation and may be located at bar With center or the approximate centre of 18.

In view of above-mentioned, it can be seen that, it is achieved that several purposes of the present invention and obtain other favourable outcome. Owing to above-mentioned structure may be made that various change is made without departing from the scope of the present invention, therefore, it is intended that, in being described above The all themes accommodated should be interpreted illustrative rather than in a limiting sense.
