Shoestring and the footwear providing this band

Technical field

The present invention relates to the footwear how a kind of shoestring provides this band.

More specifically, the present invention relates to a kind of band for climbing boot and provide the boots on foot of this band, following discloses will clearly but do not lose and mention its purposes synoptically.

Background technology

As is known, boots generally include on foot: the preferably upper vamp made with the material of flexibility of leather and/or fabric and/or other softnesses, it is configured as the pin and ankle that cover user, and be provided with extend upwardly to vamp along the region of the vertical mid-plane of boots above the bone part of the pin of vamp shin bone above region before seam, its size allows user to insert in footwear by pin; Rubber soles, it is securely fixed on the bottom of vamp by sewing up and/or gluing together, to cover the downside of the pin of user completely; At vamp internal fixtion to the arch support thing of rubber soles or inner sole; And by the protection flap made with flexible material of leather and/or fabric and/or other softnesses, it is fixed in vamp to cover seam before vamp completely.

Boots on foot described above are also provided with closes band, and it is suitable for two edges defining front seam of vamp to pull to each other, to be tightened up on the pin of user by vamp.

More specifically, the vamp of boots on foot described above is provided with a series of circle, eyelet, ring and/or returns hook, its the whole of two edges along the vamp defining front main with the relative edge stitched distributes with being of convenient length, thus roughly facing with each other on the pairs on opposing sides ground of the vertical mid-plane of boots; Close band simultaneously and be divided into two sections, interweave on the top of vamp in the front side of sewing in flexuose mode, sequentially engage a series of eyelets be arranged on the opposite side of the front seam of vamp, ring and/or time hook thus.

In current great majority on the market on foot boots, zonula occludens comprises: the tubular cylinder shape sleeve be made up of natural or synthetic textiles, it has the nominal diameter between 2 and 5mm usually, and according to the shape of vamp and multiple eyelet, ring and/or return the quantity of hook and the variable-length of position; Be called two end fittings that resistance to wear of " bracelet " with tradition, it is made up of plastics or metal usually, and is installed on two ends of tubular sleeve, thus prevents the wearing and tearing of the fabric of sleeve, contributes to band to be introduced in eyelet simultaneously.

Because it does not have inner core, zonula occludens described above is very easily bending also therefore, it is possible to be ideally suitable for the shape of the vamp of boots.In addition, if user needs to replace band, such zonula occludens can penetrate multiple eyelets, the ring on the vamp of boots rapidly and/or return hook due to its this advantage comprised.

Unfortunately, the very easily bendability of such zonula occludens to cause when the fabric of tubular sleeve surprisingly ruptures band in single eyelet, ring and/or the slip ability of returning the increase in hook due to this problem that it comprises.

Summary of the invention

The object of the invention is to manufacture a kind of band for boots and similar footwear on foot, it keeps the pliability that improves and pull resistance, and can reduce further because traditional band is at the eyelet of vamp, ring and/or return the shortcoming that the excessive slip in hook causes.

In view of these objects, according to the invention provides a kind of as propose in claim 1 and shoestring that is preferred but dispensable, that propose as arbitrary its dependent claims.

According to the present invention, provide further a kind of as propose in claim 10 and footwear that are preferred but dispensable, that propose as arbitrary its dependent claims.

Accompanying drawing explanation

Referring now to accompanying drawing, the present invention is described, accompanying drawing diagram nonlimiting examples, wherein:

Fig. 1 illustrates the perspective view of the boots on foot providing the band that instruction according to the present invention manufactures; Simultaneously

Fig. 2 is the perspective view of the shoestring shown in one section of Fig. 1 removed in order to clear part.

Detailed description of the invention

With reference to figure 1, numeral 1 represents whole nailed climbing boots, and especially, nailed climbing boots are particularly preferred for foot movement.

Boots 1 comprises basically: upper vamp 2, making with flexible material preferably by leather and/or fabric and/or other softnesses, it is shaped as the pin the bottom preferably also holding the ankle of user that hold user, and seam 3 before being provided with, it is also preferred region extension also above the bottom of shin bone above the instep of vamp 2, keep coplanar with the vertical mid-plane (not shown) of boots substantially, and the pin being constructed to contribute to user is inserted in vamp 2 simultaneously; Sole 4, is preferably made up of rubber or other antiskid elastic materials, is securely fixed on the bottom of vamp 2, to cover the downside of the pin of user completely via stitching and/or gummed; And preferably also comprise protection flap 5, its preferably by leather and/or fabric and/or other softnesses with flexible material manufacture, it is fixed in vamp 2 to cover the seam 3 of vamp completely.

Preferably but dispensable; boots 1 is also provided with the outward flange ceiling 6 be made up of vulcanized rubber or other highly elastic materials; it covers the region immediately above at sole 4 of vamp 2 completely; and for the protection of the edge of the pin of user from shock, prevent the binding site place between vamp 2 and sole 4 from leaking simultaneously.

With reference to figure 1, boots 1 also comprises a series of threading element 7, in the case, a series of circle and/or eyelet and/or winding and/or return hook, its two edge 2a along the vamp 2 defining seam 3 distribute suitably on the opposite side of the vertical mid-plane of boots; And the band 10 of predetermined length, it engages multiple threading element 7 with the mode of sliding and pass order, alternately from the side of seam 3 to opposite side, thus optionally by two of vamp 2 edge 2a towards/against pulling each other, thus the vamp 2 of boots 1 is tightened up and is limited on the pin of user.

In other words, 10 are with to be hung over to tighten up vamp 2 on vamp 2 suitably, for being limited in footwear 1 by the pin of user.

In the example shown, especially, threading element 7 distributes suitably along two edge 2a of the vamp 2 defining seam 3, preferably in the whole length of seam 3, thus be arranged in couples, roughly facing with each otherly on the opposite side of seam 3, i.e. on the opposite side of the vertical mid-plane (not shown) of boots.

Band 10 has area 3 and 30mm ²cross section between (square millimeter), and be divided into two parts/section extended in a zigzag on the top of vamp 2, sequentially and alternately engage the threading element 7 be arranged on the opposite side of the seam 3 of vamp 2, thus repeatedly mutually intersect stitch 3 before vamp above, substantially in the whole length of seam 3, thus two of vamp edge 2a are interconnected by the distance ground between possibility local directed complete set same edge 2a.

More specifically, in the example shown, band 10 is preferably provided with approximate circular cross-section, has the external diameter preferably between 2 and 6mm.

With reference to figure 1 and Fig. 2, different from shoestring known at present, the center wire core 11 preferably with approximate circular cross-section is comprised basically with 10, it has the nominal length of the total length equaling band 10 substantially, and by being called that the polychloroprene foam of neoprene is made traditionally, have preferably 0.8 and 2g/cm ³nominal density between (gram every cubic centimetre); And the outer tubular sheath 12 to be made up of natural and/or synthetic textiles, it tightens up and wraps up center wire core 11 completely.

In other words, outer tubular sheath 12 comprises a series of line, and it is interweaved suitably to be formed and tightens up and wrap up the tubing of center wire core 11 completely.

More specifically, center wire core 11 has had area preferably 3 and 30mm ²cross section between (square millimeter), and preferably by having preferably 1.2 and 1.6g/cm ³the closed pore polychloroprene foam of the nominal density between (gram every square centimeter) is made.

In addition, the breaking load of center wire core 11 is preferably 8 and 16N/mm ²between (Newton per square millimetre); The maximum breaking extension rate of center wire core 11 is preferably less than 280%, and is out of shape after the residual pressure of center wire core 11 and is preferably less than 20%.

In the example shown, especially, the cross section of center wire core 11 is substantially shaped as circle, has the outside diameter d preferably between 2 and 6mm; The center wire core 11 that polychloroprene foam is formed has and preferably equals about 1.4g/cm ³the nominal density of (gram every square centimeter).

Finally, the maximum breaking extension rate of center wire core 11 preferably equals about 260%, is out of shape and preferably equals about 15% after the residual pressure of center wire core 11.

With reference to figure 2, outer tubular sheath 12 preferably includes a series of lines manufactured by polyester, nylon or other polymeric materials of substance or duplex weave, has the number preferably between 660 to 990DTEX.

More specifically, in the example shown, the outer tubular sheath 12 that line is formed can reverse weavy grain polyester, intertexture polyester, super intertexture polyester, parallel polyester and/or the manufacture of high density weavy grain polyester by tension force.

With reference to figure 1, preferred area 10 finally also provides two end fittings 13 that resistance to wear, be called traditionally " bracelet ", it is arranged in two ends of the wire main body formed by center wire core 11 and outer tubular sheath 12, and is constructed to prevent the fabric abrasion of outer tubular sheath 12 and/or contribute to band 10 to be introduced in threading element 7.

In the example shown, especially, each end fitting 13 that resistance to wears preferably includes the tubular cylinder shape sleeve 13 be made up of plastics or metal material, it is fixedly mounted on the end of the wire main body formed by center wire core 11 and outer tubular sheath 12, and be constructed to the end that wire main body was tightened up/extruded in local, the nominal diameter of wire main body is reduced for local.

More specifically, in the example shown, each sleeve 13 is constructed to the numerical value reducing the nominal diameter of wire main body local to be preferably greater than 50%.

The operation of nailed climbing boots 1 can easily reasoning from above explanation, does not therefore need further explanation.

About band 10, in use with occur in any traditional shoestring similar, tension is supported by outer tubular sheath 12 completely, and the center wire core 11 of elastic compression can tend to the main body that outer tubular sheath 12 pressed/extrude against threading element 7, make band 10 be difficult to slide on threading element 7 thus.

In other words, the special construction of 10 is with to allow band 10 that himself elastic deformation/be compressed in threading element 7 is engaged multiple threading element 7.

This behavior allows the excessive slip of band 10 in single threading element 7 to reduce, and under any circumstance ensures that pliability and pull resistance equal pliability and the pull resistance of the shoestring only comprising the outer tubular sheath be made up of natural or synthetic textiles substantially simultaneously.

The advantage caused by the special construction of band 10 is a lot.First, band 10 contributes to tightening nailed climbing boots 1 with band, but if band 10 fracture, then prevent two of vamp 2 edge 2a broaden immediately and nailed climbing boots 1 are opened thereupon.

In addition, the advantage that the center wire core 11 of neoprene utilizes it to comprise allows to make band 10 be height waterproof.

Finally it is clear that, can nailed climbing boots 1 described above and shoestring 10 be changed and be changed, and not exceed scope of the present invention.

Such as, the outer tubular sheath 12 be formed of a wire also can by cotton or other natural fabric manufactures, and preferred process is waterproof.
