Abstract
一种具有一个用于调节横围长的隐蔽的装置的鞋履，其调节横围长的装置可以手动或自动，该装置通常含有一个装在鞋内的横围长可调节的衬里组件。
A type of footwear having a concealed means for adjusting the girth, the means for adjusting the girth may be manual or automatic, usually comprising an adjustable girth lining assembly contained within the shoe.
Description
For footwear are more fitted, footwear not only need suitable length, also need suitable inner width and the horizontal size of enclosing, and these sizes follow the corresponding size of the pin in footwear to be complementary basically constantly." the horizontal length of enclosing " described here is defined as the transversal perimeter round pin, refers generally to the girth that records at nurse toe ball, arch of the foot and the instep place of pin, these girths also be used for describing footwear corresponding site effectively in girth.In conventional footwear was carried out, so suitable applying can only realize approx by the width increment that a whole set of nine or more more classification continuously are provided for each length specification.But, even take so a whole set of separation by width, still need some further horizontal measures of enclosing adjusting adapt to that left and right sides pin is horizontal to enclose long difference and day's activities and the caused horizontal long variation of enclosing of other reasons that pin stood, such reaches one and half even two whole separation by widths usually mainly due to fluid accumulation caused variation in pin.Although so known information is arranged, but because the economic consideration of a large amount of production and sellings, pandemic in practice way is, to most of footwear is that each length specification only provides a kind of width, the result is in most of the cases can only be to fit approx, and usually be not fit very much, thereby cause serious foot's discomfort of growing with each passing day.
Owing to these reasons, people require a kind ofly width can be provided and horizontally enclose long that regulate, practical and footwear structure economy constantly, can snugly this adjusting be implemented into by some to comprise having at the bottom of the conventional footwear and the device of the various footwear types of upper of a shoe is regulated.
The adjustable horizontal long footwear shoe and stale that encloses.A lot of prior aries have adopted the visible horizontal length regulating device that encloses that comprises shoestring, pull stap and so on, but most the horizontal of nurse toe ball place that does not all adapt to pin encloses long adjusting, and are the places that needs most adjusting herein.And these devices do not appear at even that some generally do not establish this horizontal footwear type that encloses length regulating device, among the footwear type of the dress shoes worn such as the women of loafers, different back heights and other slippers and boots; In addition, people clearly demand have that automatic adjusting is horizontal encloses long footwear and carry out, and will prevent that not only incorrect staff from regulating, and such adjusting are provided will for those inconvenient people of end user's hand adjustment regulating device, for example children, disabled person and old man.
Adjustablely horizontally enclose long footwear and carry out and be disclosed in the United States Patent (USP) 3,404,468,3,541,708 and 3,686,777 of authorizing the present inventor.Because several reasons, the footwear of these patents are carried out neither one and are adapted at market sale, these patents are too complicated consequently can not be produced competitively, and when being entrained with dust, break down easily, ' 468 embodiment compares with conventional footwear and also has similar problem and durability and problem of appearance, and last three accompanying drawings (Figure 11 to 13) of ' 468 do not provide the considerable enough horizontal length of enclosing and regulate.But although many shortcomings are arranged, these patents have been enlightened the R﹠amp that finally draws considerable increase of the present invention; The D advantage.
United States Patent (USP) 3,442,031 and 3,922,800 disclose a kind of top surface at least partly by the end in improving regulates the horizontal long footwear that enclose, and this has not only changed the horizontal length of enclosing of footwear, and has raised the pin in footwear.Because in fact such adjusting is carried out in the front portion of footwear following and back comfortable fitting of group with the master who keeps leather shoes usually, so just, produced effective " trampling " effect that can change footwear, the height that promptly changes the person's of wearing heel is regulated the imbalance of the proportionate relationship of the height at nurse toe ball place.Moreover owing to horizontally enclose horizontal between the common left and right sides pin of long suitable adjusting reflection and enclose long difference, another result walks on the height that people's bipod is different in essence on the walking surface, goes down for a long time to cause serious orthopedic problem.
Though seeming has some similar but in fact significantly different United States Patent (USP)s 490 of function with the present invention, 998,2,691,227 and 3,436,842 only provide the horizontal long measure of regulating of enclosing when footwear do not carry, the present invention then provides horizontal long adjusting of enclosing not carrying and have under the carrying situation, realize to regulate under the carrying situation think even more important because caused discomfort of the footwear that do not fit and wound mainly occur under the carrying situation.In addition, latter two patents does not prevent openly that described structure from carrying the device of dust and gravel secretly.
United States Patent (USP) 3,693,270 use deformable sponge to be fixed to the inner face of boots, mainly are the insertions that will help pin and deviate from, and need not use the device of slide fastener or other expansion.But heat that produces owing to such insert of having packed into and pressure, the heat and the pressure that are particularly produced in position, nurse toe bulb have been got rid of this measure and have been used in the dress shoes and slippers of routine.
United States Patent (USP) 4,736,531 have described a kind of footwear, and this shoestring has and surrounds the anterior of pin and be fixed on the bottom parts, not securing with upper of a shoe, pad in the flexible whole toe lasting partially.Although this structure can limit flap and not align in use to prevent it, but it does not provide the horizontal length of enclosing of essence to regulate, thereby because tiny wearing in such footwear will feel that empty pine also makes pin produce and reverses by sensitive part on the nurse toe ball of the pin of bending under the situation of loop-carried of taking a step, when moving.
United States Patent (USP) 4,038,762 disclose the viscosity flowable materials that uses in sealing, mainly be used in the alpine skiing boots with rigidity sole, this measure is just as described herein, and the position, nurse toe bulb that is not suitable for the pin that sole bone/apotelus bone joint will be crooked in the walking circulation needs best horizontal conventional footwear of enclosing long adjusting to carry out.This and similarly use air, gel, gas, foamed plastics and other mechanical device measure, although the footwear shoe to the rigidity sole is useful, it is useful particularly to use when the back of nurse ball, but these measures generally not be used in position, nurse toe bulb or on nurse toe ball, this mainly be at this relatively responsive with more crucial mating area to comfortable and consideration foot's health.

Figure 14 to 16 illustrates another embodiment of the present invention, and the mode of action of this embodiment is similar to aforesaid embodiment, but some differences are arranged on the structure.This structure be designed to make present embodiment can cost factor be one main and produce with lower cost when being deciding factor.Figure 14 illustrates footwear 90, though illustrate with the form of the soft group loafers of typical tubular structure, is not limited to this type.It has the upper of a shoe made from leather or other upper material that is suitable for 92, and upper of a shoe 92 comprises big lid or toe-cap 94, and this big lid is preferably sewed up the big lid lining 98a that overlapping the slot road 96 is connected to toe lasting 100, toe lasting lining 98 and is provided with selectively by hand.These linings with can along horizontally enclose suitable material that length direction stretches, such as the New York H.L.Warshow ﹠amp of Spandex or other similar material, particularly New York; The weight that Sons company produces some and more durable Spandura make.Lining 98 is fixed firmly on the upper of a shoe 92 with some positions that the 98a that is provided with selectively is preferably in footwear.As shown in the figure, suture 91a, the wrapped belt suture 91b of the big lid lining that fixedly appear at big lid suture, is provided with selectively, back helper's seam road 91c etc. locate, and during the mode of the ailing upper stretching suture by routine is fixed to together with upper of a shoe under lining 98 securing situations at the end 102.During 104 usefulness rubber cement commonly used is fixed at the bottom of the moulding, the conventional sheet material or the moulding material that are used to make these members of 104 usefulness such as leather, plastics or rubber made at the bottom of the middle end 102 and the moulding at the end 102.At last, interior heelpiece 106 is removably inserted in the footwear 90 to improve the comfort level and the durability degree of final products.
Degree.
Figure 15 illustrates footwear, and to be through needs very little or do not need horizontal situation of enclosing on the long pin of regulating.Upper of a shoe 100 and lining 98 and 98a its interconnective position and near tight the contact, make the side of upper of a shoe and top thereof on height and width distortion to adapt to the person's of wearing pin.
As shown in figure 16, lining 98 is pulled to upper of a shoe with 98a and contacts fully with big lid, and at this moment the profile of footwear is with the profile phase ratio not distortion basically of the shoe tree of making it.Illustrate on the figure and be through one and have the position that each member of the adaptable maximum basically horizontal footwear that enclose long pin is gone up in design.
Although lining 98 is made with the most handy elasticity Stretchable fabric of 98a material, also can select for use other material or structure to come between pin and upper of a shoe, to produce variable and adjustable volume, play horizontal effect of enclosing length regulating device in the position, nurse toe bulb of footwear at least.These structures include and are used to contain the transformable air of its deal and other gas, gel, free-flowing material or with the hermetically sealed or sealable plastics of flexible foamed plastics or each seed capsules of similar material.Such foamed material comprises the closed pore moldable polyester based polyurethanes foam produced by the associating foamed product company of Georgetown, Massachusetts and other foamed material, and these foamed materials are preferably low-density, be every cubic feet 2 pounds or lower.Such foamed material can also be used to promoting horizontal elasticity of enclosing length regulating device.In such an embodiment, foamed material preferably be lined with by fabric or even cotton-shaped material make some flexible inside liners are arranged.Thisly realize that correctly sizable horizontal lining that encloses the degree of regulation of length direction should be able to provide at least one whole standard " width " regulated quantity, promptly have at least 1/4 inch horizontal at position, nurse toe bulb, arch and the instep place of pin and enclose long degree of regulation.In order to reach such degree of regulation and the proper compression rate of causing, lining should be thicker than the 1/16 inch fabric-foam liner material with 1/8 inch that is usually used in the upper of a shoe lining, and promptly initial thickness is in about 3/8 inch to 1/2 inch scope.Such thickness usually can unacceptable opening or space occur between the welt of footwear and contiguous pin, but can drop to the influence of this opening minimum or even eliminate to make and have better applying and better outward appearance between footwear and the pin by thicker foamed material being repaired to reduce at the thickness of the shoe mouth at position, nurse toe bulb, arch and the instep position of pin.Another embodiment of the present invention provides the method that the foam liner member that is used for footwear is repaired.
The method that the such foam member of many known finishings is arranged comprises initial moulding, removes the part material and tabular or sheet foam material are carried out reshaping by the processing of cutting and so on.But, relate to minimum equipment cost and the footwear type of possible wide region reached and cause the application that maximum adaptive method for optimizing relates to the thermoformable foamed material that comprises material described herein, these materials can keep reaching in about 8 to 12 minutes permanent set under about 260 ° to 300 temperature.This is easy to accomplish, by be equipped with aforesaid thermoformable, total initial thickness polyurethane foam sheet lining material preferably about 3/8 to 1/2 inch, the knit goods veneer to footwear, repair foamed material in the footwear that will complete by in these footwear, inserting a minimum horizontal profile that encloses long pin that has that this footwear design adapts to and the horizontal shoe tree that encloses size then; After shoe tree is put into footwear, by any known technology, promptly use a suitable heating furnace and introduce suitable heat by in shoe tree, feeding circulating hot oil or other fluid heating shoe tree; After cooling, the zone that the compression degree of foamed material is lower will continue to help the horizontal length of enclosing of footwear to regulate.
Another alternative embodiment (not shown) comprises between the lining of the bow portion zone side that uses the small pieces spring to be inserted in footwear and the upper of a shoe to help to regulate the horizontal length of enclosing of footwear again.This spring of going out from for example 0.010 inch thick Boping spring sheet material can preform or bending come outwards will to cover (top of upper of a shoe) under the situation of distortion greatly from pin and remain on a lower position to adapt to the horizontal needs that enclose long less pin at the upper of a shoe side.Horizontally enclose long bigger pin and will push away, and the upper of a shoe side will resisted the slight restrained force of spring assembly and be moved into an outline position littler than largest contours covering up greatly.
In all the above embodiments, should be noted that the footwear of making like this will compensate horizontal between nurse toe ball and the instep automatically and enclose long difference.This just provides than the remarkable superior cooperation of conventional structure, and is particularly all the more so in those footwear types that do not possess the conventional horizontal footwear type that encloses length regulating device, for example loafers, boots, no band slip-on shoe or the like.
