Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is made of wood or similar rigid material, the sole forming the sole, arch and heel, and a leather upper or similar covering the upper edge of the lower part. The bottom part is divided along the width of the shoe in the area between the sole and the arch of the shoe, and the two lower parts thus created have hinges firmly placed in each cross-section. Wooden shoes and clogs with associated joint soles have previously been known.

It is said that this joint should be located between the arch of the foot and the sole of the shoe, but this is because if the joint is located further forward than this, the wear of the sole of the shoe, which is connected to the arch of the foot, will be abnormally high. be.

The use of conventional metal hinges for the hinges is disadvantageous as it causes rapid wear and unduly increases the weight of the shoe.

Another problem with this is that the gap around the hinge opens and closes when the shoe is used.

The object of the invention is to have an articulated bottom which obviates the above-mentioned problems and which is considerably more comfortable to use, while
To provide wooden shoes that have a long life and are relatively economical to manufacture.

The purpose of this is to ensure that the joint surface between the arch and the shoe sole makes an acute angle with the shoe sole plane adjacent to this joint, and that the upper surface of the arch adjacent to the joint surface and above the hinge hole is brought into contact with the joint surface. A groove is formed on the inside of the bottom by cutting at an angle approximately at right angles to the base, and this groove is filled with a flexible material such as foam rubber or foam plastic to seal the joint. This is achieved by adhering to the surface.

The hinge is made of a suitable flexible material, such as waterproof rubber or plastic material, which is glued into the hinge hole and/or
Alternatively, it is preferable to fix by nailing from the inside of the bottom.

The invention will be explained in more detail with reference to the accompanying partially sectional side view showing an embodiment of a shoe according to the invention.

The shoe shown in the drawing has a wooden sole 10 and a leather or plastic upper 11 connected to this sole in the usual manner.

Naturally, the bottom part 10 may be made of a material other than wood, and the upper part 11 may also have other designs, such as having several strings fixed to the upper edge of the bottom part 10.

The bottom part 10 includes a shoe sole 12 and an arch 13 connected thereto.
, and a heel 14 that connects to the arch of the foot.

The sole and the underside of the heel are provided with an anti-wear rubber or plastic layer 15 of rubber or plastic.

As can be seen, the sole 10 is divided by a joint 16 in the area between the sole 12 and the arch 13.

This joint portion 16 is flat and forms an acute angle with the plane of the shoe sole.

A hole 17 is drilled in the joint surface of the sole and a corresponding hole 18 is drilled in the joint surface of the arch, which hole 18 corresponds exactly to the hole 17.

The edge of the arch adjacent to the joint is beveled to form a groove 20 approximately perpendicular to the joint, the sides of which are approximately perpendicular to each other.

These two shoes consist of a sole 12, an arch 13 and a heel 14.
The two bottom portions are interconnected by a hinge 19 made of a piece of flexible material, such as a suitable waterproof rubber or plastic material, which piece of material is inserted into properly matched holes 17 and 18. It is glued and/or firmly fixed by nailing from the inside of the bottom part 10.

As shown in FIG. 2, the hinge 19 is rectangular and plate-like in plan, whereas the holes 17, 18 are rectangular in shape, matching the shape of half of the hinge 19.

The groove 20 is filled with an elastic material, such as foam rubber or foam plastic.

In practice, this means that when the sole 12 and the arch 13 are in the rest position shown in the figure, the groove 20
A piece of material 21 of the same size and the same cross-sectional shape as the adhesive,
It is preferably glued to the walls of the groove 20 with a stretch adhesive.

The length of this material piece 21 is the same as or slightly longer than the groove,
Its shape is formed on the upper side and end according to the inside and edge sides of the bottom 10 after being fixed in the groove.

From the above description it is clear that the invention allows the shoe to be manufactured in an economical manner with a very simple articulated bottom.

Wooden shoes manufactured in this way are extremely hard to wear.
Mainly because of the provision of the material piece 21 within the groove 20, it is more comfortable than using prior art socks with intersegmental joint soles.

Claims (1)

[Claims] 1. The shoe has a bottom part 10 forming a sole 12, an arch 13 and a heel 14, the bottom part being made of wood or a similar solid material, and a ten part 11 or the like having a bottom part 10. It is fixed to the upper edge, and the sole part 10 is divided along the joint part 16 across the side of the shoe at the part between the sole 12 and the arch 13. The shoes are interconnected by hinges 19 fixed in drilled holes 17, 18, said hinges being connected to the bottom 1.
The joint surface 16 between the arch 13 and the shoe sole 12 forms an acute angle with the shoe sole surface, and the arch above the hinge hole 18 adjacent to the joint surface 16 is located approximately midway between the arch 13 and the shoe sole 12. A groove 20 is formed on the inner surface of the bottom by cutting diagonally so that the edge portion is approximately perpendicular to the joint surface 16, and this groove is filled with a flexible material such as foam rubber or foam plastic.
