The specific embodiment

Below, with reference to accompanying drawing an embodiment of the invention are described.Fig. 1 is the stereogram of the Shoe for infant that relates to of expression one embodiment of the present invention.With reference to Fig. 1, Shoe for infant 10 comprises: sole part 11, and it is positioned at child's underfooting; Vamp skin zone 12, it covers infant's instep; Tongue portion 13, it is connected with vamp skin zone 12, and covers the top of infant's instep; Footwear side skin zone 14, it is connected with vamp skin zone 12, and covers the two sides of infant's pin.

Shoe for infant 10 has connecting band 17, and the end of this connecting band 17 above footwear side skin zone 14 be by being formed at the space of tongue portion 13, and extends to the footwear side skin zone of opposite side.Connecting band 17 is fixed in the side end above the footwear side skin zone 14, and end side is fixed in the footwear side skin zone 14 of opposite side by surface fastener spare 18.Therefore, the surface fastener spare 18 of the footwear side skin zone by opening opposite side can make infant's pin be easily inserted into the inside of footwear 10.

And as shown in Figure 1, the vamp skin zone 12 of Shoe for infant 10 and footwear side skin zone 14 constitute by the mesh cloth of nylon system.

Fig. 2 A is the figure of the sole part 11 of expression Shoe for infant 10 shown in Figure 1, and Fig. 2 B is the cutaway view of part shown in the b-b of Fig. 2 A.With reference to Fig. 2 A and Fig. 2 B, in the position that is used to place infant's toe of sole part 11, the position of the opposition side of the bottom of the position of arch of the foot, arch of the foot and arch of the foot, be provided with the ventilating part that constitutes by net.Here, the position 21a to 21c of the toe in placing toe except that thumb and the part of arch of the foot 24a to 24c, be provided with bigger woven wire, and on the opposition side position 26 of the bottom 25 of the leading section 23 of the thumb position 22 of pin and footwear, arch of the foot and arch of the foot, be provided with a plurality of less woven wires 21 to 26.And, the placement location of toe slightly below be provided with through hole 27.And, the size that the size of net can select small stone and less foreign matters to invade.

And with reference to Fig. 2 A, woven wire 21 to 26 is set in the sole 11, and on every side by (line that surrounds net in Fig. 2 A is represented recess) in the recess that protuberance surrounded, and directly do not contact with outside.

And net is not limited to woven wire, as long as have the intensity of regulation, also can be made of reinforced plastics etc.

With the position adjoining position of the arch of the foot of the central portion of sole part 11 on, be provided with stable pad 50.Sole 11 is made of the TPR (thermoplastic elastomer) of hardness 45.In addition, stable pad 50 is made of the TPR identical with the material that constitutes sole 11, but its hardness is the hardness 60 that is higher than sole 11.

Here, if footwear are of a size of 16cm, then the size of stable pad 50 is about 49.5mm.At this moment, the size from the heel side end of the footwear of stable pad 50 to the end of the heel side of footwear is about 47mm, and its width is about 11.5mm.And the stable pad 50 outstanding sizes to sole are about 6mm.

And, as the main component of the TPR that constitutes this stable pad 50, for example can use: the material of SBS (styrene) 80%, PS (polystyrene) 8%, calcium carbonate 5%, paraffin oil 5%, stearic acid 2%, but be not limited to this.

Secondly, the position that is provided with of stable pad 50 is described.Fig. 3 is a pin bone internal anatomy.The pin bone roughly is divided into three zones, that is, be made of the area B of phalanges (toe bone), the zone C of metatarsal, the region D of shank.The metatarsal arch 30 in pin the place ahead is a so-called instep bow, and it is not real bow, but changes because of the load that applies.The adult is when walking, because deadweight metatarsal arch 30 can be squeezed.Under adult's situation, the crossbows 31 of shank portion does not produce the variation of the bow that causes because of deadweight.

Because infant's pin is soft and fatty more, under the unsettled state of the state that contacts and apply deadweight with ground and pin, the shape of pin can change.Applying under the state of deadweight, it is big that the width of pin becomes, the height step-down of instep.On the other hand, under the unsettled state of pin, the width of pin diminishes, and the height of instep uprises.

The infant can catch ground by crooked toe point when standing.Facilitate this action meeting relevant with the formation of arch of the foot.Carry out smoothly for the action that can make this toe, must stably support metatarsal arch 30.Because metatarsal arch 30 is the positions that can not retrain toe movement, even the therefore fixing tightly motion that also can not hinder toe.

So, in the present embodiment, in order to fix this metatarsal arch 30 tightly, and at metatarsal arch 30 to stable pad 50 is set between the crossbows 31 of shank portion.

Like this, stablize pad 50 to being provided with between the crossbows 31 of shank portion, can follow by feet, and prevent to produce in the walking distortion by metatarsal arch 30 at sole.

The position that should stablize pad 50 is based on baby's medical science, child-bearing engineering calculation Design goes out.Therefore,, cooperate child's foot to grow and make footwear crooked, can provide a kind of thus and not hinder the nature walking, and walking like can promoting barefoot, and considered the footwear that infant's foot is grown in the metatarsal part by stable pad 50 is set in this position.

And in Fig. 2 A and Fig. 2 B, only the central portion at sole 11 is provided with stable pad 50, but is not limited to this, also can strengthen width.

Secondly, the concrete shape of stable pad is described.Fig. 4 represents to be formed with the adult's of arch of the foot vola.Arrow is represented among the figure body weight moves when being walking track.If move at the center when noticing adult's walking, is heel ground connection at first, center of gravity moves to the outside of pin then, moves to first metatarsal bone bone portion by fifth metatarsal bone bone portion again, and leaves away from the front end of thumb (first refers to).

Therefore, the shape that the body weight the when shape of stable pad 50 also is preferably along walking moves moves thereby produce this center of gravity.Like this, also the width generation center of gravity to pin moves, and can obtain sense of stability, and make the walking progress, thereby form desirable arch of the foot on infant's pin.

Fig. 5 A and Fig. 5 B are the figure of the concrete shape of the stable pad 50 of expression.Stable pad 50a shown in Fig. 5 A presentation graphs 2A, Fig. 5 B represents its variation.With reference to Fig. 5 A, stable pad 50a is shaped as the band shape with Rack, and shown in arrow among the figure, have from heel and extend to the tiptoe direction, and thereafter to the curve part of footwear inside bend.And, shown in Fig. 5 A, the stable point-symmetric shape in its center relatively that is shaped as of filling up 50a.

With reference to Fig. 5 B, the shape of the stable pad 50b that variation relates to, identical in toe side with stable pad 50a, but have approximate rectangular shape in heel side.Be set as shape shown in Fig. 5 A and Fig. 5 B by stablizing pad, help the formation of above-mentioned arch of the foot.

And,,, be provided with a plurality of grooves along the curve part of above-mentioned bending in the zone that more is positioned at the sole of toe side than stable pad 50 with reference to Fig. 2 A.
