Description

Footwear sole and arch strapping system

Technical field

The present invention relates to shoes.Specifically, the present invention relates to be used for shoes are fixed in strapping system on user's pin reliably, and relate to and be used for providing the shanks of rigidity and supporting role for footwear sole.

Background technology

There are various prior aries to show the tether construction that is used for shoes at present.Usually, the effect of this frenulum can be summarised as shoes are fixed on user's the pin, and used in conjunction with sandals often.

Showing the example that sandals or shoes frenulum be provided with the prior art of situation comprises: the U.S. Patent No. 4,200,997 and 4 of authorizing Scheinhaus, 446,633, authorize the U.S. Patent No. 4,679,334 of McBride, authorize the U.S. Patent No. 3 of Park, 3247,410, authorize the U.S. Patent No. 4,793,075 of Thatcher, authorize the U.S. Patent No. 4 of Saltsman, 817,302, authorize the U.S. Patent No. 4,300,294 of Riecken, authorize the U.S. Patent No. 2 of Gibson, 788,591, authorize the U.S. Patent No. 2,126,094 of Daniels and the U.S. Patent No. 2 of authorizing Ellis, 862,311.Each piece in these patents all disclosed usually and some combinations at ankle, heel, instep, toe, arch of foot or these positions fit constructs with the frenulum on the pin that shoes is fixed in the user.But, without any a prior art, and also can fully satisfactorily shoes be fixed in other existing frenulum structure and can also keep comfortable, the durable and convenience of constructing on the pin simultaneously in these prior aries without any a kind of existing frenulum structure.This problem is outstanding especially for employed sandals at the volley or in other powerful activity.Because it is in these aggravating activitieses, the people who wears sandals has become more and more, therefore, also more and more higher for the requirement of frenulum structure.There is not a kind of known existing sandals frenulum structure aprowl to carry out the nature adjusting with respect to pin and ankle; And these adjustings can strengthen user's comfort, and easy to use.

There is a particular problem relevant with ankle or instep strap.Because the angle between pin and the ankle can change in the process of normally walking or run, therefore, will alternately tighten up and loosen along the downwards anterior of leg and the pin master tendon that passes the instep of this pin.This can make the overall circumference of ankle and instep increase or reduce.This ankle all must be considered this expansion and contraction around any frenulum operation of living, it is necessary to make this frenulum to make compensation the variation of size.If there is not this compensation, the ankle frenulum is the excessively motion of restrict foot just.

Existing shoes frenulum mostly be towards one not with walking, run or powerful active procedure in the corresponding direction of force vector that taken place be orientated.Frenulum normally becomes approximate 90 ° angle to be orientated with relative these shoes.This angle has only when the straight ground of frenulum and just is suitable for make frenulum intensity for maximum when being positioned on the instep with shoes with paralleling.But when the top of pin turns forward, therefore, shoes are that the frenulum at 90 ° of angles just must reverse so that energy be positioned on the instep of inclination straightly relatively.So just make the user feel uncomfortable, and can reduce the intensity of frenulum.

Some other existing shoes frenulum structure is a characteristic with a continuous frenulum, it be around such as ankle, the pin that crosses a plurality of positions on instep and the pin front portion and wearer is contacted.Because the motion of the other parts of pin, these frenulums can not keep tightening in active procedure.A kind of continuous frenulum that for example covers instep and forefoot because the motion of forefoot, it on instep continuously, tightening just may be not enough aspect the cooperation.

Except the shoes strapping system, the also still unresolved other problem relevant with respect to pin motion of prior art with shoes.Specifically be difficult to walking, run or other powerful active procedure in provide torsional rigid, arch support and overall stiffness for sole.Though a kind of soft and damping substantially sole forefoot and heel portion are comparatively ideal for making the wearer feel comfortable, they may make sole desirably soft and " soft ".In order to prevent this state, the shanks that a kind of relatively firmer and rigidity can be provided is with soft, that owe rigidity forefoot and heel portion bridge joint.Shanks than rigidity can also provide torsional rigid for sole, thereby can prevent to walk to occur disagreeable twist motion in the process in the big walking of wearer.

The shanks of prior art comprises: the metallic plate in the middle sole region in being plugged between sole and an outsole or the insole; One is attached to the side direction made on the bottom outsole in the sole region, by rubber or other material in described than narrow (being commonly referred to as " fiddleback shanks "); And it is molded or be bonded in other plastic member that zone, sole foot stage casing is used to provide supporting role and rigidity.But the shanks of these prior aries can not prevent and generally all can not construct to such an extent that can offset the type of reversing of the twisting resistance that produces fully in wearing the footwear process, and especially those are by the active force that frenulum produced that passes sole.

Therefore, still exist for the many demands that do not have solution of shoes.What need for a long time is a kind of shoes frenulum structure that can adapt to the broad range of movement of pin in motion or other powerful active procedure always.In addition, needing frenulum dynamically to do self according to the needs in the use regulates.And, still need one all-in-one-piecely to have firm and shanks portion rigidity, so that provide torsional rigid and stiffness for shoes forefoot portion and heel portion relatively soft and damping.

Summary of the invention

The first embodiment of the present invention comprises that a kind of footwear of uniqueness construct with frenulum, and it can provide dynamic fit adjustment a sole reliably and cosily can also be fixed on wearer's the pin simultaneously.Described frenulum structure comprises an adjustable X-shaped frenulum substantially, and it is attached to the heel portion of shoes in a certain way, and process from wearer's the instep is passed one then and is arranged in the sole of shoes and is positioned at lateral trench below wearer's the arch of foot.Even the present invention comprises that also adopting this also can be the shoes that are fixed in the unique frenulum structure on user's pin with shoes reliably in motion or other powerful activity.

This adjustable X-shaped instep strap has first end that is fixed in first side of shoes heel portion substantially, described frenulum reaches forward laterally from wearer's instep and passes through, pass the groove in the footwear sole in sufficient middle section, pass the longitudinal center of sole, reach backward then and laterally return the instep that crosses the wearer and extend (on instep, forming an X thus), and with described frenulum adjustable ground and be fixed in second side of the heel portion of shoes releasedly.Described groove can be by the back to preceding longitudinally downward-sloping, the downward-sloping direction that is parallel to wearer's instep, thereby frenulum is positioned on wearer's the instep straightly, can bears the active force that in motion or other powerful activity, is created between pin and the sole thus more equably.

This X-shaped instep strap can be fixed in wearer's pin on the footwear sole.This frenulum preferably passes sufficient stage casing groove below wearer's arch of foot, the horizontal sufficient stage casing part of sole can be fixed in the bottom of wearer's pin thus.
