Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the sole of a sandal that is attached to the lower surface of a sandal stand.

[Conventional technology]

Conventionally, in the sole of this type of zori sandals, for example, as shown in FIG. An auxiliary member 5 is made of an elastic material such as rubber or synthetic rubber and has a protrusion 4 integrally provided on the lower surface of the sheet portion 3. The auxiliary member 5 is pressed down from the upper side of the bottom main body 1 to insert the protrusion 4 into the hole 2. A configuration in which the sheet-shaped portion 3 is fitted onto the top surface of the bottom main body 1 and the tip of the protrusion 4 protrudes from the bottom surface of the bottom main body 1 is known.

[Problem that the invention attempts to solve]

Since the above-mentioned known device does not have a U-shaped groove around the protrusion 4, the waterproof effect is not necessarily good, and the incisal edge of the hole 2 is likely to peel or break, as well as The incisal edge remains exposed, which is undesirable from an aesthetic point of view. Furthermore, if there is a difference between the size of the protrusion 4 and the size of the hole 2, the gap between the outer peripheral edge of the protrusion 4 and the incisal edge of the hole 2 There are disadvantages such as the width of the gap that is formed tends to be uneven, making alignment difficult.

[Means to solve the problem]

The present invention consists of a monolithic bottom body with holes of a predetermined shape formed at required locations, and a height such that the tip protrudes below the bottom surface of the bottom body when it is fitted into the hole from above. An auxiliary member made of an elastic material such as natural rubber or synthetic rubber is integrally provided on the bottom surface of the sheet-like part, and the protrusion is fitted into the hole from above, and the sheet-like part is fixed to the top surface of the bottom body. In the sole of zori sandals, which have a combined structure, a sideways projecting edge is integrally provided on the upright wall surface of the protrusion, and a U-shaped groove is formed around the protrusion, and the bottom is inserted into this groove. The above-mentioned problems are attempted to be solved by fitting the incisal edge of the above-mentioned hole formed in the main body.

[Effect of invention]

The present invention is as described above, and the overhanging edge and U-shaped groove contribute to improving the waterproof effect and preventing peeling and breakage, and also hide the incisal edge of the hole for a good appearance. This also alleviates the above-mentioned gap and eliminates the difficulty in positioning.

[Example of idea]

The embodiment shown in the figure has a monolithic bottom body 11 made of foamed synthetic rubber, and has a relatively large hole 12 in the front half of the bottom body 11 and a tongue-like lid piece 13 for closing the thong with a rear knot. An auxiliary member 17 in which a hole 14 is cut and, separately, a protrusion 16 thicker than the bottom body 11 is integrally provided on the lower surface of a sheet-like portion 15 made of raw rubber material and containing a coarse woven cloth 15'. A horizontal projecting edge 18 is integrally provided on the upright wall surface of the protrusion 16, and a U-shaped groove 19 is formed around the entire circumference of the protrusion 16. Similarly, the protrusions 16 are fitted into the holes 12, and the sheet-like portions 15 are placed on the upper surface of the bottom body 11.
are fixed to each other with adhesive (not shown), and furthermore, a front tie hole 21 is cut in the protrusion 16 of the auxiliary member 17 and has a tongue-shaped closure piece 22 integrally attached to the incisal edge. The lid piece 22 is made by overlapping and pasting a raw rubber thin piece 23 that is one size larger than the lid piece 22 on the back side of the closing tongue-shaped lid piece 22.
An edge piece 24 is provided around the periphery of the lid piece 2.
When closing 2, the periphery of the lid piece 22 and the front knot hole 2
It is inserted between the incisal edge of 1 as a packing to perform a waterproof function.

In some cases, the inner surface of the groove 19 and the cutting edge 20 of the hole 12 are not fixed by adhesive, and in such a case, the groove 19 is made to strongly impact the cutting edge 20 of the hole 12.

[Effects of the invention] As described above, the present invention consists of a monolithic bottom body in which holes with a predetermined shape are opened at required locations, and a bottom body that, when fitted into the holes from above, An auxiliary member made of an elastic material such as natural rubber or synthetic rubber is integrally provided on the lower surface of the sheet-shaped part with a protrusion of a height that protrudes below the lower surface, and the protrusion is fitted into the hole from above, and the sheet-shaped part is In the sole of zori sandals, which are integrated by being fixed to the upper surface of the sole body, a sideways projecting edge is integrally provided on the raised wall surface of the protrusion, and a U-shaped groove is formed around the protrusion. , and the above-mentioned incisal edge is fitted into this concave groove, so that the projecting edge and the U-shaped groove act as described above, thereby solving the problem that the present invention aims to solve. This has the effect of sufficiently achieving resolution.
