Description

The footwear structure of adjustable girth

For pin is more fitted, not only need suitable footwear long, and need suitable inner width and girth size, these sizes in fact with footwear in the corresponding size of pin match closely.Here employed " enclosing length " is defined as the transversal perimeter around pin, typically is meant the girth that orbicule, arch of the foot and instep place at pin record, and these girths also are used for describing the effectively interior girth of same area footwear.In traditional footwear, this applying can only be by satisfactory size range, for example footwear are divided into 9 or more multistage mode of according to its length dimension footwear being widened step by step again be similar to realization.Yet; however divide the width level fully; still need some other circumference adjustment device to change the left and right sides bottoms degree difference that is caused with the difference that adapts to left and right sides bottoms degree and by daily routines and some other degree of enclosing by pin; wherein the variation of indication is mainly due to due to the accumulation of liquid in pin, and this species diversity can reach 1.5 even 2 full width dimensions levels usually.Although this is well-known problem, yet the economic conditions of producing in batches and selling general limitation most of footwear, these footwear only provide a single width to each length dimension, the result in most of the cases can only be similar to fit and usually do not fit, thereby makes pin be in serious imbalance state for a long time.

Owing to these reasons, people more and more press for a kind of practicality and footwear structure economy, this structure is carried out width and degree of enclosing by certain device and is regulated, and described device can allow a kind of like this adjustability relatively snugly, promptly provide wide range comprise conventional soles and upper of a shoe the footwear type.

The footwear of adjustable girth are also stale, a large amount of technology has formerly been used and has been comprised the visible circumference adjustment device of shoestring, pull stap and so on, great majority in these devices are difficult to be adapted to the degree of enclosing at the orbicule place of pin and regulate, and be the place that needs most adjusting herein, yet, in different various women's shoes of the footwear that typically do not have circumference adjustment device such as loafers, heel height and footwear such as many other accidental footwear of wearing and boots even this circumference adjustment device also do not occur.In addition, need clearly definition, not only will avoid inappropriate hand adjustment, and this adjusting device will be offered those and use other the inconvenient people of hand adjustment device, for example child, disabled person and old man in some aspects for the footwear that automatic circumference adjustment device is arranged.

Also open in the United States Patent (USP) 3,404,468,3,541,708 and 3,686,777 that the footwear that degree of enclosing is adjustable have been authorized.For some reason, neither one is opened and is sold the road in these patents, these reasons are: two patents in back are too complicated, to such an extent as to can not produce competitively, and when accompanying earth in the mechanism, be easy to produce fault, also there is similar problem in 468 embodiment, compares except durability and outward appearance with traditional footwear, and last three accompanying drawings (11-13) of 468 do not provide considerable degree of enclosing and regulate.Yet although these technology have many deficiencies, they are enough to inspire and finally draw the R﹠amp of the desired adding of the present invention; The D advantage.

United States Patent (USP) 3,442,031 and 3,922,800 disclose and have a kind ofly made the adjustable footwear of degree of enclosing by the top surface that is increased to the end in the small part footwear, and this has not only changed the degree of enclosing of footwear, simultaneously pin has been raise in footwear.Owing in fact generally be to carry out this adjusting in the front portion of footwear with the hard part that keeps the upper of a shoe rear portion with the rear portion is comfortable fits, so just produced the imbalance adjusting of orbicule relative altitude that " trampling " effect that can change footwear promptly changes the person's of wearing the relative pin of heel.Moreover because suitable degree of enclosing is regulated degree of the enclosing difference that has reflected usually between the pin of the left and right sides, another result who is produced is that people's pin is inconsistent in the travel height on above-mentioned walking surface, and this has brought a series of orthopedic problem.

Though outward appearance and this are invented some similar but diverse United States Patent (USP) 490 of actual functional capability, 998,2,691,227 and 3,436,842, only degree of enclosing is regulated measurement when footwear do not carry, degree of enclosing adjusting of the present invention then is suitable for not carrying and two kinds of situations of carrying is arranged, and the latter does not seem even more important because the improper caused pin of footwear does not accommodate damage for majority under the carrying situation.In addition, two patents in back do not prevent openly that silt and gravel pebbles from clipping to the device in the said mechanism.

United States Patent (USP) 3,693,270 fasten deformable sponge and fix in the boots, and this mainly is to be easy to wear footwear and to take off one's shoes, and needn't be with slide fastener or other degree of tightness mechanism.Yet wearing fashionablely, particularly boots grinds out-of-date generation heat and pressure from the orbicule of pin, thereby makes this boots be not suitable for use in the common footwear that wear and wear occasionally.

United States Patent (USP) 4,736,531 have described a kind of footwear, be provided with half Elastic Sliding liner around the front of pin and be fixed on the base assemblies and freely be attached to upper of a shoe in these footwear.Yet this structure may limit flap in use and make it to be difficult to align, like this, when narrow wearing in the footwear, when the sensitizing range, orbicule top that weight bearing exceeds pin in taking a step to circulate just makes the position that pin can flexible motion, make footwear produce lax, fold, also just can't reach basic degree of enclosing and regulate.

United States Patent (USP) 4,038,762 disclosed be in welt, to adopt viscosity plastically deformable material, this structure is mainly used in the alpine skiing footwear boots with hard end, as wherein said, it needing at the orbicule position of pin to be not suitable for the common footwear of best degree of enclosing adjusting.At the MP(of orbicule place of pin bone/phalanges) flexible engagement in the walking circulation.Though this material and the similar close materials such as air, gel, gas, foamed plastics and other mechanical device that use are to footwear of the hard end, orbicule rear portion in particular for pin is particularly useful, but the general position of not using it for orbicule or surpassing orbicule.This has mainly considered the comfortable and healthy of at this responsive relatively and crucial mating area pin.
