Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a device for preventing burying in snow, which is suitable for walking on snow.

<<Prior Art>> When walking on snow, especially when there is a lot of snow, the feet may become buried in the snow if only shoes are worn.

Therefore, when walking on snow, "snowshoes" as shown in FIG. 6 have been used to prevent the feet from getting buried.

In the figure, snowshoes 3 include an elliptical frame 1 with a larger diameter than the sole of the shoe, and are configured to be attached to the back side of the shoe (not shown) via a string 2 provided in the center. There is.

《Problems to be solved by the invention》 However, in the case of snowshoes as described above, the user walks along with a large-diameter frame attached to the back of the shoes, and there is a lack of sense of unity between the shoes and the snowshoes. Therefore, there was a problem that the user felt uncomfortable while walking.

Furthermore, snowshoes have to be attached to shoes with laces each time they are used, which is not only inconvenient to use, but also unsightly.

<<Purpose of the invention>> In view of the above-mentioned problems, the object of this invention is to provide a device for preventing burying in snow that can be used without discomfort while walking, has excellent fashionability, and is easy to use.

《Means for solving the problem》 This invention is made of an elastic material and has a mounting part that is attached to the outer periphery of the shoe, and a mounting part that is connected to the mounting part and expands in the horizontal direction by pressure from below. The present invention relates to a device for preventing burying in snow, characterized in that it has a fin portion that does.

<<Description of Embodiments>> Next, embodiments of this invention will be described based on the drawings.

FIG. 1 is a front view of the first embodiment to which the present invention is applied, in which three snow burial prevention devices 4 made of rubber material are provided on both sides at the lower side of the boots 10.
is provided.

FIG. 2a is a cross-sectional view taken along the line - - in FIG. 1, and the snow burial prevention device 4 is glued and fixed to the side wall of the boots 10 via the attachment portion 4c, and is connected to the attachment portion 4c. fin part 4 that extends downward
It is equipped with b.

On the other hand, as described above, since the snow burial prevention device 4 is made of a rubber material, when pressure is applied from below to the fin portion 4b of the snow burial prevention device 4 in FIG. 4b will be expanded upward.

The first embodiment is configured as described above, but
Next, the boots 1 equipped with this snow burying prevention device 4 will be explained.
We will explain the operation when walking on snow wearing 0 shoes.

As described above, when pressure is applied from below to the fin portion 4b of the snow burial prevention device 4, the fin portion 4b expands upward using the bent portion 4a as a fulcrum.

Therefore, when walking on snow wearing the boots 10 equipped with the snow burial prevention device 4, the fin portion 4b of the snow burial prevention device 4 gradually moves horizontally with the bent portion 4a as a fulcrum due to the pressure of the snow. It will open to

Figure 2b shows the snow S from below as described above.
The figure shows a state in which the fin portion 4b of the snow burial prevention device 4 is opened in the horizontal direction due to the pressure.

As described above, when walking on snow, the fins 4b of the snow burial prevention device 4 open horizontally. and,
When walking on snow, the resistance to the snow increases accordingly. Therefore, it is possible to walk without the foot being buried.

By the way, the snow burial prevention device 4 according to this embodiment
is fixed to the boots 10 via the attachment part 4c with adhesive, and is provided integrally with the boots 10.
When walking on snow, the soles of the boots are in direct contact with the snow surface. Therefore, compared to conventional snowshoes, you can walk on the snow without feeling any discomfort.

In addition, since it is fixed with adhesive, there is no trouble in attaching and detaching it, and it can be easily used as a snow burial prevention device.

In this embodiment, six anti-burial devices are attached to each boot, three on each side, but the number of devices can be changed as needed.

Next, a second embodiment of the present invention will be described based on FIG.

In addition. Components that are the same as those in the first embodiment are given the same reference numerals, and detailed explanation thereof will be omitted.

The feature of this second embodiment is that the snow burial prevention device 4
0 over the entire circumference of the boots 10,
The snow burial prevention device 40 is provided integrally with the boots 10 via the attachment portion 4c from the beginning of the manufacture of the boots.

Therefore, in this example, together with the attachment part 4c, the fin part 4b is also provided along the entire circumference of the boots 10 so as to be continuous with the attachment part 4c.

Thus, in this example, as shown in FIG. 3, the snow burial preventive device 40 is provided over the entire circumference of the lower side surface of the boots 10, so as to maximize the resistance against snow during walking. There is.

The expansion operation of the fin portion 4b in this embodiment is exactly the same as that in the first embodiment, so detailed explanation thereof will be omitted (see FIGS. 2a and 2b).

By the way, the feature of this second embodiment is that, as mentioned above, the snow burial prevention device 40 is provided integrally with the boots 10 from the beginning of the manufacture of the boots.

Therefore, the size and design of the snow sinking prevention device 40 can be adjusted in accordance with the size and design of the boots 10, and boots for snow sinking prevention that are functional and rich in fashionability can be manufactured.

Next, a third embodiment of the present invention will be described based on FIGS. 4 and 5.

Note that the same members as in the first embodiment are given the same reference numerals, and detailed explanation thereof will be omitted.

The feature of this third embodiment is that the snow burial prevention device is of a fitting type and is detachable.

That is, in FIG. 4, the snow burial prevention device 4
1 has substantially the same shape as the lower part of the boots 10, and when in use, this snow burial prevention device 41
It is constructed such that it is sufficient to fit the lower part of the boot 10 therein.

FIG. 5 is a cross-sectional view taken along the - line in FIG.
In the snow burial prevention device 41 in this embodiment, the mounting portions 4c provided on both sides are integrated through the bottom portion 41a, and a fin portion 4b is provided in series with the mounting portion 4c. .

In addition, also in this example, the fin portion 4b is provided over the entire circumference.

As mentioned above, this third embodiment is configured to be detachable as a fitting type.

Therefore, the snow burial prevention device can be worn by simple means only when walking on snow.

In addition, in this example of the snow burial prevention device, the snow burial prevention device is removable, but it is fitted with the boots and used as an integral part, so unlike when using snowshoes, it is possible to walk without feeling discomfort.

In each of the above-mentioned embodiments, each snow burial prevention device is made of an elastic rubber material, but the rubber used includes natural rubber and various other synthetic rubbers.

Further, in each of the embodiments, the fins are provided on the snow burial prevention device, but it goes without saying that a fin of an appropriate size can be selected depending on the weight of the user, the size of the boots, etc.

<<Effects of the invention>> As mentioned above, the snow burial prevention device according to the present invention is made of an elastic material, and has a mounting part attached to the outer circumference of the shoe, and a device connected to the mounting part to prevent pressure from below. Since the device is configured to have fins that expand horizontally, it is possible to walk on the snow without the feet being buried in the snow, and the user can walk on the snow without feeling uncomfortable. It has effects such as obtaining.
