Abstract

The utility model relates to a pair of insoles. Either insole is suitably dented at both end metatarsi of the transversal foot arch, massage gaskets (1') and (2') with different densities are respectively added below the dents. When the foot arch exerts force on the insole, both end metatarsi of the transversal foot arch fall in the two dents for ensuring the physiological curvatures of the transversal foot arch and simultaneously receiving the massage function of the gaskets. Gaskets with different densities are likewise arranged at the contact part of either insole with a heel for ensuring the physiological curvatures of the longitudinal foot arches. A downward concave structure is likewise formed on the contact surface of the toes and either insole according to the contour line of the toes of a human body, and a massage gasket (3) is added. A connecting sheet (5) with good toughness is mounted at the waist at the back of either insole so as to ensure the stability of long-term wearing.

Description

Doube bridge props up the overfill protection health insoles

Technical field

The utility model relates to a kind of shoe-pad, and especially a kind ofly foot crossbows and longitudinal arch are carried out doube bridge prop up overfill protection, and the shoe-pad that keeps healthy by massage point.

Background technology

Arch of foot is that shank and metatarsal borrow it to link the protruding bow that makes progress of formation, is called as arch of foot.As Fig. 1, shown in 2,3, in primate, have only human foot to be based on the form of bone and to form significantly arc.Arch of foot is dynamic, and it has constituted indivisible complex on the function with muscle, ligament.Arch of foot can be divided into the medial and lateral longitudinal arch of fore-and-aft direction and a crossbows of inward-outward direction traditionally.

Arch of foot has increased sufficient elasticity, makes foot become rubber-like " tripod ".As shown in Figure 1, the gravity of human body is delivered to caput metatarsale and tuberosity of calcaneus through astragalus to forward and backward from ankle-joint, thereby guarantees the steadiness that the vola lands and supports when upright, the effect of performance elasticity and buffering concussion in walking and when jumping.Arch of foot also can protect blood vessel, the nerve in vola to avoid compressing, reduces the impact of ground in the face of health, avoids concussion with protection intracorporeal organ, particularly brain.

Keeping except the binding that relies on each bone of arch of foot, the traction of the ligament in vola and the long and short tendon in vola also plays an important role to keeping arch of foot.Though these ligaments are very tough and tensile, lack initiatively contractility, in case be elongated or impaired, arch of foot just might subside, and becomes flat foot.When the convexity of tab sole of last of footwear is excessive, put on such footwear, crossbows was stayed before pin will cause, and formed the reverse arc shape structure.Fig. 4 is bow structural change schematic diagram.If wear such footwear for a long time, can cause the lax of ligament, fatigue, damage, thereby forfeiture elasticity, crossbows is difficult to reply original arching before making.

Arch of foot is human peculiar, runs at human body, walks, all plays an important role in all doing more physical exercises such as jump, so in design, pay special attention to protect arch of foot, keeps the normal physiological function and the physiology and appearance of arch of foot.Therefore protect arch of foot or the performance that the effect of arch of foot is more perfect, just become the research and development emphasis of this " doube bridge props up the overfill protection health insoles ".

Simultaneously, pin is on the dirty and brain position farthest of centroid, is the more unattainable organ of blood conduction.Increase the motion of foot, can stimulate circulation, so pin is also referred to as second heart of human body.

The blood circulation function of pin a little less than, the venous return deficiency just can cause the accumulation of local acid metabolic waste.Pin has important role to the health of human body.Foot also is the places that channels and collaterals are concentrated, and the neural reflex district that is associated with partes corporis humani position organ in addition under foot by stimulating these neural reflex districts, and then can improve the microcirculation of foot's blood vessel.Fig. 5 is foot vascular distribution figure.Outdoor all is the motion process of a long-time long distance generally on foot, and how allowing foot be in a comfortable space in whole persistent process and giving comfortable foot's induction also is important research and development content of this shoe-pad.

good brace

5,5 of a slice toughness is housed simultaneously and adopts the TPU material, given sole longitudinal arch lower muscle and skin and better supported well, increased comfortableness simultaneously.

(1) composition and the functional analysis of " doube bridge system "

Design according to ergonomics is remembered with gratitude, design according to human body sole curve and arch curve, done simultaneously suitable recessed 1 in the sole emphasis force part of shoe-pad, 2, and below sunk part, add the expanded material or the elastomeric material pad 1 ', 2 ' of different densities, as PU, EVA, latex or silica gel.When sole to the shoe-pad application of force time, sole crossbows two ends metatarsal falls within two

sunk parts

1,2, and middle bossing can be close to the crossbows face 7 that arches upward, thereby has guaranteed the physiological bending of foot crossbows.

In shoe-pad and heel contact portion, the expanded material or the elastomeric material pad 4 ' of different densities have been designed equally, as PU, EVA, latex or silica gel are when s heel portion to the shoe-pad application of force time, the pad of s heel portion deforms, with the heel calcaneum according to heel curve land in heel cup groove 4, the intermediate projections part 8 of shoe-pad is close to the longitudinal arch face that arches upward simultaneously, has guaranteed the physiological bending of foot longitudinal arch simultaneously.

Under the support of " doube bridge system "; article two, the natural physiological curve of arch of foot has all obtained natural protection; the slight concave configuration of vola stress surface has improved the stability that the vola lands and supports when upright; the expanded material of different densities or elastomeric material pad 1 '; when also can and jumping in walking, 2 ', 4 ' application given play to the effect that increases elasticity and damping.

(2) possesses the functional design of the echo area of exciting nerve

In order to realize stimulating massage functions for circulation, so this shoe-pad is provided with two massage districts, respectively in forefoot part of the

force

1,2, and the contact-making surface 3 of toe and shoe-pad.

" first massage district " is positioned in the

depressed part

1,2 at transverse palmar arch two ends before the shoe-pad, in the massage district even row portion the dome-type massage point of dimpling.The major function in massage district is in order to increase the blood circulation at the volley of sole part, because the important stress surface of forefoot is just distinguished in first massage, when the people is standing, under walking or the motion state, this part will be subjected to bigger pressure, and because the existence of subcutaneous phalanx and metatarsal, will produce very big pressure, so subcutaneous arteries microcirculation meeting is subjected to very big pressure, so in going on a hike for a long time, because blood circulation has some setbacks, the decline gradually of oxygen content in the blood, the beginning of acidic metabolite accumulates gradually, so be easy to the sensation that produces fatigue or ache.

As very long open air process on foot, small neural stimulation can to one long-term and clocklike process impact, can rhythmical stimulation and the neural reflex district of massage sole.Reach the promotion venous return, and effectively evacuated the accumulation of step acidic metabolite.

" second massage district " is positioned on the contact-making surface of toe and shoe-pad 3, and this massage district is a concave configuration of forming according to the outline line of person's toe, this in recessed slightly massage district same even row portion the dome-type massage point of dimpling.First function in this massage district is with the above-mentioned consistent toe portion blood circulation at the volley that promoted; Second function is to have improved toe to contact with the sensitivity of shoe-pad, strengthened the frictional force of toe and shoe-pad, gives the wearer better stability.The moulding of slight depression cooperates the hemispherical dome structure of dimpling, has increased the contact area of sole and shoe-pad, and the moulding of dimpling simultaneously more provides the sense of toe with grabbing.Because the people in walking, not only needs to adjust balance by anklebone and arch of foot, equally also need a lot of body structures to coordinate, such as the center of gravity of regulating trunk, utilize arm to increase the whole sense of equilibrium, also comprise of the influence of the application of force of toe to whole center of gravity.Through test, when the people when losing center of gravity, five toes can open by natures, and make great efforts to grab ground under subconsciousness, whole physiological phenomenon explanation, open toe can produce bigger contact area, thereby gives the better sense of equilibrium; The behavior of grabbing ground simultaneously also is to be desirable to provide better stability.

So the second massage district has just in time adapted to people's whole physilogical characteristics, recessed moulding is rational to provide bigger contact area, the massage point of dimpling not only provides and has more given better sense of toe when losing center of gravity to the massage of toe blood microcirculation with grabbing, thus the balance of easier adjustment health.

(3) functional brace 5

The shoe-pad back waist is equipped with the good brace 5 of a slice toughness, and brace can be TPU, nylon, polypropylene, polyester or polystyrene.The moulding of brace designs according to ergonomics, and is narrow in the middle of two hem widths, and the waist of interior receipts is replenished by the pad material of thickening, given sole longitudinal arch lower muscle and skin and better supported well, increased comfortableness simultaneously; The enhancing of the brace of shoe-pad shoe-pad toughness compression strength; foot is stable extremely important when walking out of doors; shoe-pad is a significant element that directly contacts with pin; so not only replenished toughness and the stability that the bottom is divided in the whole sole in the brace structure that insole layer increases; more stable vola protection can be provided when walking, guarantee the firm of long-term dress back shoe-pad moulding simultaneously.
