Abstract

PROBLEM TO BE SOLVED: To prevent snow or ice including water from being retained at the lower surface of a sole by successively forming a grounding member layer with many cylindrical parts communicating with a gap so as to form the gap part between the lower surface of a stepping surface part through a plurality of ribs at least on the lower surface of the stepping surface part of the sole of the footwear. SOLUTION: The grounding member layer 2 is integrally formed through the gap part G on the stepping surface part except an arch part 1a and a heel part 1b at the sole surface of a shoe. This layer 2 is formed by integrally suspending many cylindrical parts 2b on the lower surface of a plate part 2a and the parts 2b open downward their lower tips (free tips) on a side in contact with a road surface and open their upper tips toward the upper side of the part 2a. In addition, between the stepping surface part and the layer 2 of the shoe 1, ribs 3 for forming the gap part G are arranged six by six, e.g. radially from nearly the center part of the stepping surface part. Thereby, snow and ice sent from the cylindrical holes of the parts 2b to the part G are speedily discharged to the outside of the part G.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to footwear, such as shoes, which are used mainly when snowing and the like and do not slip even when walking.

[0002]

2. Description of the Related Art In areas where there is a large amount of snow or areas where there is temporary snow, ordinary footwear such as boots and boots must be used to prevent accidental slipping and falling during walking. A plurality of protruding ridges, such as high saw-tooth shapes, which are not seen in the above, are arranged in parallel.

In footwear having such high saw-toothed ridges or the like, when walking with this ridge, each ridge acts to receive the weight of a person and bite into snow. Utilizing the gripping force of the ridges against the snow by this action, the shoe sole functions so as not to easily slide on the snow upper surface.

[0004]

However, in such conventional shoes such as boots and boots, the rubber material forming the ridges is formed relatively hard to secure the grip force. In addition to what is being done, snow or ice containing water or water that has entered between the ridges stays clogged, so that this ridge makes it difficult for each ridge to bite into the snow on the road, In reality, there is a problem that the ridge does not sufficiently serve as a slip stopper, and the occurrence of the overturn accident is not sufficiently eliminated.

The present invention has been made to solve the above-mentioned problem. In order to prevent snow and ice containing water from staying on the lower surface of the shoe sole, the snow and ice swallowed once from the lower surface of the shoe sole and the like. Aiming to provide footwear that can walk safely without slipping on snowy or icy roads by enabling the efficient drainage of shoes to the outside of the sole through another street And

[0006]

In order to achieve the above object, a footwear according to the invention of claim 1 has a plurality of ribs protruding at least on a lower surface of a tread portion of a footwear sole. A grounding member layer having a plurality of cylindrical portions communicating with the gap portion is continuously provided so as to form a gap portion extending from the central portion to the peripheral portion between the tread surface portion and the lower surface. .

In the footwear according to the second aspect of the present invention, the plurality of ribs are provided radially from a substantially central portion of the tread portion.

In the footwear according to the third aspect of the present invention, the tread portion is curved so as to increase from a substantially central portion to a peripheral portion.

The footwear according to the invention of claim 4 is such that the grounding member layer is curved so as to become thinner from the center portion to the peripheral portion.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIGS. 2, 3 and 4 are a front view, a bottom view and a bottom perspective view showing a shoe 1, which is the footwear of the present invention. In the figure, reference numeral 2 denotes an arch part 1a and a heel part 1b of the bottom face of the shoe. Tread surface 1c excluding
In addition, a grounding member layer integrally provided with a gap G as shown in FIGS. 1 and 5.

The grounding member layer 2 is made of, for example, a molded article made of rubber or synthetic resin having elasticity, which is slightly soft.
It has a form in which a large number of cylindrical portions 2b are integrally formed to project downward from the lower surface of a. Therefore, the lower end (free end) of the cylindrical portion 2b on the side in contact with the road surface opens downward, and the upper end opens above the plate portion 2a.

The lower end of each of the cylindrical portions 2b does not necessarily have to be a uniform surface as a whole, but may have an irregular cut surface. Further, as shown in FIG. 5, it is desirable that the plate portion 2a is curved so as to gradually decrease from a substantially central portion thereof toward a peripheral portion thereof. Accordingly, the cylindrical portion 2b is formed highest near the center of the plate portion 2a and lowest near the periphery.

Reference numeral 3 denotes ribs which are interposed between the tread surface portion 1c of the shoe 1 and the grounding member layer 2 to form the gap G, and these ribs 3 are substantially central portions of the tread surface portion 1c. For example, six lines are provided radially from.

Here, these ribs 3 can be formed integrally when the grounding member layer 2 is formed, and may be formed integrally with the sole of the shoe 1 when the sole is formed. The ribs 3 may be attached to the bottom of the finished boots using an adhesive, and the ground member layer 2 may be attached to the lower surfaces of the ribs 3 using an adhesive.

In the boots having such a configuration, when a person wears the shoes on his / her feet and walks on a snow melting road or on a frozen road after the snow melting, the cylindrical portion 2b of the grounding member layer 2 is formed by a somewhat soft rubber or the like. Therefore, by receiving the weight of a person, the lower ends of these cylindrical portions 2b bite into ice or snow, and function to hold a snowy road surface or an icy road surface.

[0016] For this reason, while the cylindrical portion 2b is appropriately bent, snow, ice, snow melting water, or the like is swallowed from below into the cylindrical hole of the cylindrical portion 2b. Is fed into the gap G between the ribs 3 from the inside of the cylindrical hole.

Further, as described above, the plate portion 2a of the grounding member layer 2 is inclined so as to be lower in an arc shape from the center portion toward the peripheral portion, and the tread surface portion 1c of the boots 1 is positioned from the center portion. Since the gap G is gradually widened from the center to the periphery by being inclined so as to be higher in an arc shape toward the periphery, the gap G is increased.
The snow-melting water, snow or ice sent from the cylindrical hole of the cylindrical portion 2b is quickly discharged out of the gap G.

That is, the snow and ice do not stay in the cylindrical portion 2b as in the prior art, and the lower end of the cylindrical portion 2b always holds the road surface of snow and ice. The grip force on a snowy or icy road surface is increased, and slipping can be reliably prevented. As a result, it is possible to avoid a fall accident during walking and a fracture or bruise accident due to the fall accident.

In the above embodiment, the boots are shown as an example, but it goes without saying that such a non-slip structure can be applied to other boots, sandals, and any other footwear.

[0020]

As described above, according to the present invention, a plurality of ribs protrude from at least the lower surface of the tread portion of the sole of the shoe, and the rib is provided between the rib and the lower surface of the tread portion from the center thereof. Since the grounding member layer having a plurality of cylindrical portions communicating with the gap is formed so as to form a gap extending toward the peripheral portion, the snow-containing bottom surface of the shoe sole contains water. In order to prevent snow and ice from stagnating, these snow and ice once swallowed from the underside of the shoe sole can be efficiently discharged to the outside of the shoe sole through another path, and can be removed on snowy roads and icy road surfaces. The advantage is that the user can walk safely without slipping at all.

According to the second aspect of the present invention, the plurality of ribs are provided radially from a substantially central portion of the tread portion, so that snow, water or ice swallowed in the cylindrical portion can be quickly removed. In this way, it is possible to efficiently guide the air to the gap between the grounding member layer and the sole of the footwear so that the air can be discharged to the outside efficiently.

According to the third aspect of the present invention, the tread portion is curved so as to increase from a substantially central portion toward a peripheral portion thereof, so that snow, water or ice can be combined with the ground member layer. The effect of being able to quickly discharge from the gap with the shoe sole to the outside using the weight of the person is obtained.

According to the fourth aspect of the present invention, the grounding member layer is curved so as to become thinner from the center to the peripheral portion thereof, so that snow, water or ice can be removed from the grounding member layer. The effect of being able to use the weight of the person to quickly discharge from the gap between the shoe and the sole of the shoe and out of the gap is obtained.
