Abstract
The invention discloses a pair of boots special for military parade and a manufacturing method thereof. The sole of each of the pair of boots comprises a boot insole made from a polyurethane material, a boot outsole made from a rubber material 1 and a heelpiece made from a rubber material 2. The uppers and the boot outsoles of the boots are connected through the boot insoles formed by filling the polyurethane material, and the soles are provided with textures. The soles of the boots are hard and light and are resistant to abrasion, and the strength of the heelpieces are high. The pair of boots special for military parade produces a sonorous voice when being in contact with the ground in parade-step walking and is comfortable to wear. Rubber and plastic abrasion-resisting pieces are designed on the inner sides of the outer wrapping soles of the boots. The heelpieces are asymmetrical in structural design, and the comfort level during wearing is improved. Shoelaces are of irregular structures and are obvious in tying effect, and shoelace storage belts arranged on tongues facilitate storage of the exposed parts of the shoelaces so as to keep the appearance of the boots.
Description
Technical field
The present invention relates to one to review troops special purpose shoes boots and preparation method thereof.
Background technology
Reviewing troops is a national activity having Special Significance with army. The personnel that consult mainly complete queue traveling training and show, are different from general training, and queue is advanced and trained physical consumption big, training strength is high, the demands such as footwear boots comfortableness, ruggedness is higher, it is necessary to carry out special purpose shoes boots research of reviewing troops, meet the queue traveling particular/special requirement to footwear boots.
Queue traveling training includes in step and stride. Being the conventional footwork advanced of soldier in step, the essential of exercise is, left foot steps about 75cm to dead ahead, lands according to the order of first heel hind paw, simultaneously centre of body weight reach, and right crus of diaphragm is method action like this, gait of march 116��122 steps per minute. Stride is mainly used in march-past, the essential of exercise is, left foot kicks out of about 75 centimetres to dead ahead, and lower limb is exceptionally straight, presses under tiptoe, sole is parallel to the ground, overhead about 25cm, suitably firmly makes full sole land, simultaneously centre of body weight reach, right crus of diaphragm is method action like this, gait of march 110��116 steps per minute. More conventional training, to army waiting for inspection's queue traveling neat and consistent, the officers and men's action norm that is reviewed requires more sternly, standard is higher. The officers and men that are reviewed add up to be 10 hours training time every day, and training strength is high, and the physical ability to officers and men is a kind of test, for footwear boots, is also a kind of test close to the limit in comfortableness, ruggedness.
Being different from conventional footwear boots, review troops and use footwear boots, team of side has particularity and specificity with footwear boots especially on foot, is embodied in: one is affected by high pressure training, and footwear boots of reviewing troops should possess good ruggedness. Being affected by queue traveling action feature and high pressure training, footwear boots of reviewing troops are very easily impaired, and concrete condition shows as vamp and broken hole occurs, and sole anti-skid design is smoothed, and main portions is bosom and sole in toe-cap inboard, boot upper heel. More conventional footwear boots, footwear boots footwear material of reviewing troops should possess good anti-wear performance and resistance to performance of colliding with. Two is that leg of a boot design meets foot motion, improves comfort property. The footwear boots leg of a boot of reviewing troops design should be soft, facilitates the foot pressing action that stretches tight during stride, wraps with needs particular design after upper of a shoe meanwhile, it is to avoid causes mill pin problem because heel material stacking is wrinkling during the underfooting pressure that stretches tight. Three is during queue is advanced, and footwear boots sole of reviewing troops lands megaphonia, clear and melodious. Team of the side of consulting emphasizes spring heel position during quick march, sole full facies palmaris megaphonia when landing when stride is advanced, clear and melodious, when advancing with conventional operation boots, sole possesses silencing function and contradicts, it is necessary to for this particular/special requirement design specialized footwear sole construction and decorative pattern. Four is that team of side spring heel is provided that human body powerful support on foot. Team of the side of consulting requires that spring heel wants hard, is provided that human body powerful support in step, it is to avoid health rises and falls with heel material crimp, and then affects uniform queue effect during walking. By investigating, make caliga special functional demands for army waiting for inspection, it is necessary to carry out special footwear boots research of reviewing troops.

The outer low design of this inner height matches with the distribution of foot heel skeletal muscle, improves snugness of fit.
The resistance to sheet that collides with of rubber and plastic:
Queue traveling training requirement, every sufficient front tip part bit interleaving touches cherishes leg after position keeps one's balance and thus kicks out of in heel, therefore, heel of a shoe is inboard easily damaged, sews the resistance to rubber and plastic sheet that collides with at this position, improves and wear intensity. This rubber and plastic sheet material TPU is modified to be made and hardness is 90A.
The preparation method of special purpose shoes of reviewing troops boots, comprises the steps: 1) the heel fluffing of footwear boots outer bottom and elastomeric material 2 preparation, wash 2min, 30��35 DEG C of brush coating 2��3min twice when 60 DEG C, 2��3min is activated when 60 DEG C; Upper of a shoe fluffs, and fluffs by edge, rim of the mouth, does not answer sand wound to help foot, and the fluffing degree of depth is not to be exceeded 1/4 that leather is thick;
2) at upper of a shoe flank position, the viscous hook heart, the viscous polyurethane foam of heel region fill out core, use PUR to be adhesively fixed, just should glue, cement;
3) by step 2) process after upper of a shoe dry, dry 1��2min when 80 DEG C, footwear boots outer bottom is heated 80 DEG C, 1��2min, and then upper of a shoe overlaps shoe last or hat block, set just, set flat;
4) being initially charged rubber outsole in a mold, inject polyurethane material and obtain the end in footwear boots, rim of the mouth and abutment wall decorative pattern clearly, do not come unglued between the footwear boots big end and upper of a shoe, fully, foamed glue and outer layer rubber are firmly combined with, not starved, then depanning in foaming;
5) by step 4) the dress shoe last or hat block sizing of the footwear boots that obtain, dress shoe last or hat block puts in place, does not answer wrong number, and cryogenic temperature is-5 DEG C, time 10min; Repairing mouth of a river glue, mouth of a river glue should be cut and only repair together, should not injure sole; Appearance modification, it is bright that vamp throws polishing, then joins shoe pad, namely obtains the present invention and reviews troops special purpose shoes boots, as shown in Figure 2.
