Referring now to attached drawing to be best understood from the present invention, the representative band of one or more articles is surrounded and fixed in Fig. 1 It is total in be indicated with reference numeral 10.As shown in Fig. 1 etc., band 10 is included in the tapered end 16 of one end and the tail in the other end The slender member in portion 46.Elongated-strip-article 18 extends between tapered end 16 and tail portion 46.Tail portion 46 can be inserted into tapered end 16, be used for item Band is locked around one or more articles to be fixed.Tapered end 16 is accommodated for keeping elongate strips 18 and the ball of tail portion 46 22.Tail Portion 46 tapered end 16 can be inserted into along first direction and when being moved along the second direction opposite with first direction by tapered end 16 and The engagement of ball 22 is kept, to which tail portion 46 to be maintained in tapered end 16.The general structure and function of band discussed in this article It is more fully described below in the commonly assigned patent of entitled " the Cable Tie " of publication on June 20th, 2000.The patent application To be all included in a manner of herein.

When one or more articles tie-down around such as steel bar beam 14 or steel pipe bundle 12, ball 22 is in tapered end 16 in order to prevent Thus middle movement is also prevented from tail portion and moves backward in a second direction and tapered end 16 is avoided to unclamp, formed to multiple in body 18 Forming undulation is used to reinforcing strip body 18 around one or more (as shown in reference numeral 26a, 26b, 26c in Fig. 1 etc.) The tie-down of article 12,14.In various embodiments of the present invention, forming undulation can amount to just 4,5 (such as attached drawings Mark 26a shown in), 6 (as shown in reference numeral 26b) or 7 (shown in 26c).More or fewer wavy of formings Volt is also regarded as within the scope of the invention.It is attached that forming undulation 26a, 26b or 26c can be formed in tail portion 46, tapered end 16 Close or any other position in elongate strips 18.Band 10 have the advantages that high-tensile, be lightweight, have length make With the service life, it is simple to manufacture and economical.

In a preferred embodiment, the tapered end 16 of the disclosed invention, band body 18, ball 22 and all other element are all by stainless steel It is formed, to allow band for various temperature ranges, and assigns band high-tensile and excellent in harsh weather Good rotproofness.Such as 304 stainless steels (being alternatively referred to as A2 stainless steels or 18/8 stainless steel) or 316 stainless steels can be used Steel.It should be appreciated, however, that band 10 can by such as include aluminium, brass, copper, other types of metals of iron or even plastics its Its material is configured to.Other configurations can be used, and are all considered as within the scope of the invention.In embodiment, for example, Ball 22 can be substituted with the similar substantial cylindrical lock pin being engaged by locking of permission.

The band 10 of the present invention from band volume (not shown) according to the application of band 10 preferably by obtaining appropriate length first The elongate strips 18 of degree are formed.In an embodiment of the present invention, for general availability in many applications, elongate strips 18 have the length between 26 inches and 27 inches.Alternatively, elongate strips 18 can have 200 millimeters (" mm "), 260mm, The length of 360mm, 520mm or 680mm.As another alternate embodiment, elongate strips 18 can have 190mm and 200mm it Between, between 250mm and 270mm, between 350mm and 370mm, between 500mm and 540mm or 650mm and 700mm it Between length.In various embodiments, the width of elongate strips 18 can be 4.6mm, 7.9mm or any other width (or, replacing Dai Di, between 4mm and 5mm or between 7mm and 8mm).The next step of manufacture band 10 is formed in elongate strips 18 Forming undulation 26a, 26b or 26c.In one embodiment, elongate strips 18 are formed in the mould punching in press In undulation 26a, 26b, 26c.For manufacturing purpose, for each forming undulation, it is most useful that with other It shapes undulation (as shown in reference numeral 85 in Fig. 4) and forms 60 degree of angles, or any angle between 55 degree and 65 degree, because Such angle can be stamped and formed out with the primary of mold.In order to utilize the disclosed invention, it can also use an angle of 90 degrees (in such as Fig. 5 Shown in reference numeral 85 ') or any angle between 85 degree and 95 degree, but undulation as formation may need to make it is elongated Band 18 passes through mold punching press more than once.Elongate strips 18 are limited by principal plane 4a and the secondary plane 4b to completely contradict, such as Fig. 6 As drawing.

Then, tapered end 16 is preferably formed by generally rectangular-shaped general plane metal stock (not shown).Such as Fig. 6 It is shown, so that the top 32 for being closed completely domed form is formed in the central part of metal stock first.Preferred real It applies in example, preferably as shown in fig. 7, opposite rectangular notch 34a and 34b is subsequently passed through metal stock and is formed in opposite edges 36a On 36b, to leave or be folded into top when the opposite segments 38a and 38b for the blank for including notch 34a and 34b are bent together When portion 32 makes notch 34a and 34b and edge 36a and 36b be in direct relativeness below, they define tapered end 16 Bottom 40 below top 32.In this way, notch 34a and 34b associated are to limit the substantially square hole 42 across bottom 40.Metal The corresponding bending region of blank limits the side wall 44a and 44b of tapered end 16, and surrounds top 32 and cover the metal stock of bottom 40 Part limits top plate 43.Thus, it can be seen that side wall 44a and 44b make top plate 43 and bottom 40 be connected with each other.

Then, the hole 42 in bottom 40 will be passed through to be inserted into lock preferably by the tourelle of the band 10 of the form of ball 22 First 16.In the case where tapered end 16 is oriented so that the holding of ball 22 is suitably located in head 16, head 16 can be slidably mounted To on the band body 18 of tail portion 46 so that bottom 40 is adjacent to second surface 20b.On this position, top 32 and top plate 43 cover It covers on the first surface 20a of band 18, it is noted that ball 22 is fixed in head 16 with being captured by top 32 and band 18.Item It is folded up at perforation 66 with 18 first end 30, and protrusion 28 is inserted into simultaneously latch and in one hole 42, is thus consolidated tapered end 16 Surely band 18 is arrived.

As best illustrated in figs. 6 and 7, tapered end 16 includes band upstream end 50, band outlet end 52 and exists across tapered end 16 The band receiving channel 54 extended between both ends, band receiving channel 54 is partly by top plate 43, side wall 44a and 44b and bottom Portion 40 limits.Top plate 43 can be covered in the relationship substantially parallel with bottom 40 on bottom 40.Top 32 preferably includes One and the straight divergent portion 56 of second substantially and 58 and generally arcuate convergence portion 60.First and second divergent portions, 56 He 58 is diverging from one another along the direction of outlet end 52 with bottom 40.In a preferred embodiment, the second divergent portion 58 has than the first hair Dissipate the small angle of divergence in part 56.On the contrary, arcuate section 60 is assembled with bottom 40 along the direction of outlet end 52 to each other.Head 16 Outlet end 52 is also used as the reaction force face of the nose of traditional taut band tool (not shown).

As shown in Fig. 1-6 and 8-10, undulation 26a, 26b, 26c include amounting to 4 forming undulations, 5 26a, 6 A 26b, 7 26c, 8 or more multiple forming undulations.In a preferred embodiment, multiple forming undulation 26a, 26b, 26c can only extend from the principal plane opposite with secondary plane 4b.In alternative embodiments, undulation is shaped from elongate strips Both 18 principal plane 4a and secondary plane 4b extend.As shown in figure 4, in embodiments of the present invention, each forming undulation can It is formed between 55 degree and 65 degree with other forming undulations or the just angle of 60 degree (as shown in 85).As shown in Figure 5 Separate embodiments in, it is each to shape undulation and be formed between 85 degree and 95 degree with other forming undulations or just The angle of 90 degree (shown in such as 85 ').Note that in fig. 4 it is shown that the element 85 at 60 degree of angles shows with reference to 5 forming undulation 26a Go out, and in Figure 5, shows that the element 85 ' of an angle of 90 degrees is shown also referring to 5 forming undulation 26a ', it is noted, however, that being discussed Angle can be used in combination with any amount of forming undulation being formed in elongate strips 18.Undulation can be neighbouring Head is formed elsewhere.In embodiments of the present invention, all forming undulations can have the length less than 1 inch.

With reference to Fig. 8-9, such as tourelle of ball 22 can pierce into the position (threading) in tapered end 16 from shown in Fig. 8 It sets to latched position shown in Fig. 9 or locked position movement, is piercing into position, ball 22 can be set to against adjacent tapes outlet end The arcuate section 60 at 52 top 32, in latched position, 22 wedge of ball leans against the divergent portion 58 at top 32 and is brought into closer to item Between the band 18 for entering end 50, and then 18 wedge of band is made to lean on bottom 40, thus usually prevents band 18 from it in tapered end 16 Latched position moves backward.As it is used herein, term " wedge " or " wedge leans on " meet its broad sense, simply to indicate to lock at it On position, ball 22 and band 18 are extruded or are compacted.

The operation of band 10 is as follows：After band 18 is deformed to wrap up article 12 or article group 14, the tail portion with body 18 46 pass through band upstream end 50 to be inserted into tapered end 16 along the first direction as shown in the direction of arrow A.When continuing in the direction of arrow A When piercing into through channel 54, band 18 contacts ball 22, to make it be promoted and be moved to position shown in Fig. 8 of piercing into.It should manage Solution, since ball 22 can roll on strip 18 during piercing into, piercing into for band only needs very small power.This will The much bigger prior art band for piercing into power is completely different with needs, in prior art band, it is necessary to force and be biased to The lock tongue of its latched position deflects into it and pierces into position.The first direction shown in the arrow A passes through persistently piercing into for channel 54 dynamic Work causes band 18 to be left from tapered end 16 by band outlet end 52.Band 18 is pulled through tapered end 16 until it is tightly enclosed Predeterminated level is arrived around article 12 or bundle of objects 14, as shown in Figure 8.

Tightened position as shown in Figure 9 is the tension of the insertion and band 18 due to tail portion 46 in head 16 and generates 's.As that can be seen in Fig. 3 and 8-9, the tension of band 18 can be used for making in spring-like manner wavy of forming 26a, 26b or 26c is lied prostrate to extend.The reaction force applied when being stretched by forming undulation 26a, 26b, 26c is used for along such as Second direction shown in arrow B applies sizable power, to keep band to be connect around the locking of one or more articles to be fixed It closes.

With reference to Fig. 9, after band 18 is tightened to predeterminated level, unclamp band 18 and with from forming undulation 26a, The power of 26b or 26c cooperates, and elongate strips 18 and ball 22 second direction shown in the arrow B is caused to be moved to band upstream end 50 Or it retreats until ball 22 simultaneously engages with top 32 and band 18.As shown in FIG. 8 and 9, ball 22 pierces into position and latched position at it Between stroke it is very short.When ball 22 is in its latched position, between ball 22 and top 32 and between ball 22 and band 18 Frictional engagement be typically enough to prevent ball 22 from rolling, to cause band, tightly wedge leans on bottom 40.In addition, with edge as described above The associated power of forming undulation 26a, 26b, 26c that second direction shown in arrow B is stretched can be further strengthened and be prevented Ball 22 rolls, to by promoting locking of 18 wedge of band by bottom 40 come strengthening strip 18 in head 16.It is wavy by shaping The vitality that fluctuating 26a, 26b or 26c apply in the direction of arrow B also tie-down of the maintaining item band 18 around article 12 or 14.It is opening When beginning to lock, ball 22 also realizes that the permanent deformation of band 18, the impression cause the previously piece of tape below ball 22 by impression Material actually becomes cold flow, forms the rim around impression.

Figure 10 shows the alternate embodiment for the present invention for being generically designated as reference numeral 10 '.Band 10 ' substantially with bundle As band 10, be only shown as 26a ', 26b ' or 26c ' forming undulation 26a, 26b or 26c be located at it is another on band 18 Position, such as outside head 16.In another embodiment, forming undulation can be located at band 18 center or substantially in The heart.

In view of above-mentioned, it can be seen that realize several purposes of the present invention and obtain other favorable outcomes.Due to upper Stating construction can be made without departing from the scope of the present invention so that various changes can be made, therefore, it is intended that, be described above accommodated in it is all Theme should be interpreted it is illustrative rather than in a limiting sense.
