PATENTED MAY 2 7 I975 SHEET DEDF 2 INFANT CHILDREN S SHOE BACKGROUND OF THE INVENTION This invention relates to an infants shoe which is made by cementing the heel to the shoe sole. This shoe heel is formed in a shape such as bounded by its inner lateral rim, rear rim and outer lateral rim extending fOF ward from its rear part and also forward rim of arcuatc eoneaveness.

When an infant child was wearing various conventional shoes which did not readily give a stability to his standing posture, a normal movement of his center of gravity by walking motion was impeded, making his walk extremely unstable. Thus, he was liable to fall during the walk. This causes the infant to have a fear complex from walking, getting him behind the time to commence his walk. And if he is forced to walk with such conventional shoes worn, it is feared that the growth and development of his foot would be affected badly.

An object of the present invention is to provide an infants shoe that eliminates said disadvantage of the conventional shoes, thereby enabling the infant child to take a natural and stable standing posture lest he should be slow in commencing his walk, and in order that, through a posture like this, a normal growth and functional development of his foot is insured and promoted.

DESCRIPTION OF INVENTION RELATING TO DRAWINGS The construction of the infants shoe of this invention will be clearly shown below by explanation of the ac companying drawings.

Referring to the drawings of the infant childrens shoe of the present invention, FIG. 1 shows a perspec tive drawing relative to the first embodiment of the present invention, as viewed diagonally from below;

Then, FIG. 2 is a drawing of the face of the shoe shown in FIG. 1;

FIG. 3 shows a cross-sectional view as made along the line A to A in FIG. 2;

FIG. 4 shows a perspective drawing of the second embodiment of the infants shoe of the present invention, as viewed diagonally from below;

FIG. 5 shows a drawing illustrating the face of the sole of the shoe illustrated in FIG. 4; And finally,

FIG. 6 is a cross-sectional view as made along the line B to B.

In the embodiments illustrated in FIGS. 1 to 3, the whole of the outsole member la and upper member lb is formed undivided and in one piece. In these embodiments of invention, the space for shoe heel is cut from the outsole at the corresponding heel position, in a shape such as made by its inner lateral edge, rear edge and outer lateral edge extending forward about halfway of the length of the outsole and also forward edge of arcuate concaveness that runs from the front end of said inner lateral edge to the front end of said outer lateral edge.

All of these inner lateral edge, rear edge and outer lateral edge are located somewhat inward from the periphery of the shoe outsole.

The heel 2 to be attached is formed in a shape such that its inner lateral rim, rear rim, outer lateral rim and forward rim all would conform with the respective corresponding edges of the part as above mentioned of the outsole having been cut from it.

The insole 3 is cemented onto the back of the outsole, and the heel is inserted to the part cut through in a manner that its respective rims would conform with the corresponding edges of the part of the outsole cut through, then it is cemented to the insole. Therefore, it comes that the inner lateral rim, rear rim, outer lateral rim and forward rim of the heel held in place, are in conformity with corresponding inner lateral edge, rear edge, outer lateral edge, and forward edge of the part cut through of the outsole, respectively.

In these embodiments, the shoe outsole la is cut through so that the heel 2 of the shoe would be placed in position through the part cut through for cementing. However, in the stead of doing so, the heel may directly be cemented onto the exterior side of the outsole.

In this invention, it is not necessarily specified that the whole of the outsole member and the upper member is continuous in making. These two members may also be assembled together by stitching or cementing.

Next, the second category of embodiment will be described below, referring to FIGS. 4 to 6;

The insole member 11a and upper member llb of the shoe are made continuous and in one piece. The outsole member 13 is cut through so that the forward edge of arcuate concaveness running from the outer lateral edge that extends about halfway forward on this shoe outsole, to the inner lateral edge is provided to the shape of the cut through part. Here, said inner lateral edge, rear edge and outer lateral edge are provided somewhat inward from the corresponding part of the periphery of the shoe outsole. Said outsole member is cemented onto the exterior face of the insole member 1 la.

The heel 12 is formed in a shape bounded by its inner lateral rim, rear rim, outer lateral rim and forward rim, every one of which will conform with the respective corresponding edge of the cut-through part of the outsole member.

Said heel is placed in position through the cutthrough part of the outsole member in a manner that its every rim will be in conformity with the respective corresponding edge of the cut part, and is cemented to the insole member.

Alike the preceding embodiment category, in these embodiments, the heel may directly be cemented to the outsole member, in the stead of inserting the heel through the part cut through the outsole member at the heel position and cementing it to the insole member. Besides, the shoe must not necessarily be made so that the whole of its outsole member and upper member are continuous, that is to say, these two members can be stitched or cemented together.

In the infants shoe of the present invention, how much the heel 2 or 12 in its respective case would be lofted from the outsole member 3 or 13, i.e., the actual heel elevation is not particularly confined. However, the adequate elevation is about 0.5 to 1.0 mm. Besides, the material of said heel is not limited to a particular substance. However, in view of the heel being for the infants shoe, natural or synthetic rubber is preferable for slip-proofing purpose.

Furthermore, any substance suitable can be used for making the shoe of the present invention. Non-woven fabric or cotton fabric can be used other than leather.

Since the infant childrens shoe of the present invention is constructed as described above, due to some 0.5 to 1.0 mm elevation of the foot sole of the part located above the shoe heel of the invention. weight and force works on such elevated part of the foot sole more than on other part thereof, whereby while an infant is standing or making foot steps, with this shoe being worn the foot can be prevented from staggering outward. This. at human beings most important period from the time of standing straight to the time to commence walking. as well helps him stand in a natural and stable posture and promotes a development of his normal foot functions as enables him to make an accurate and safe foot step motion. Furthermore, the heel appearing exposed from the shoe sole works as a mark for identification of the shoe, thereby making it easy to find the shoe of the purpose of this invention at a retail shop. And, finally the shoe has an additional advantage of having said heel which works as a slip-proofwhile wearing it. These are extremely unparalleled advantages of the referred shoe.

What is claimed is:

l. A shoe construction, comprising an upper, an outsole secured to said upper having rear, outer side, inner side and front edges and having a slot defined through said outsole at the heel spaced inwardly from each side and rear edge and which extends substantially one half way down the outer side edge of the shoe from the rear edge and only about one quarter of the way down from the opposite inner side edge from the rear edge, the front edge of the slot being concavely arcuate from the outer side edge to the inner side edge. and a heel of the same configuration and substantially the same size as the slot extending through the slot and having an inner portion with an interior face secured to said upper.

2. A shoe construction according to claim 1, wherein said upper ends and outsole are formed of a single piece and including an insole disposed within said upper secured to said outsole and to said heel.

3. A shoe construction according to claim 1, wherein the interior surface of said heel is flush with the interior surface of said outsole.

4. A shoe construction according to claim I, wherein said outsole is separate from said upper and is secured to the bottom exterior of said upper, said heel being secured to the outer surface of said upper.

5. A shoe construction according to claim 4, wherein the interior top surface of said heel is flush with the interior top surface of said outsole, said heel being thicker than said outsole and projecting outwardly therefrom.
