Description

[Detailed description of the invention] The present invention aims to solve the following problems.

(Industrial Application Field) This invention relates to footwear.

(Prior Art) There has been a problem that when the temperature drops in winter, the peripheral parts of the body, especially the feet, tend to get cold.

(Problems to be Solved by the Invention) The present invention aims to eliminate the above-mentioned conventional problems and provide footwear that can warm the toes and create a comfortable condition.

The configuration of the present invention is as follows.

(Means for Solving the Problems) The present invention takes the measures as described in the claims above, and its effects are as follows.

(Function) When the footwear is worn with the heating element placed in the heating element housing, the front half of the foot is warmed by the heat generated by the heating element. In this case, the fluid heat-generating material in the bag of the heat-generating element can be distributed and positioned on both left and right sides of the front half of the foot in a luggage-like manner.

In this state, the heat-generating materials on both sides warm the feet from the sides, and at the same time, the warmth of the heat-generating materials is transmitted to the part located above the feet within the bag, warming the feet from that location as well. Furthermore, since the heat generating material is distributed in the form of luggage as described above, the stationary state of the heat generating body within the storage section is stably maintained.

(Embodiments) The drawings showing the embodiments of the present application will be explained below. In FIGS. 1 to 4, reference numeral 1 denotes a bottom element, which is formed in a size corresponding to the sole surface of the foot. When the footwear is home socks, the bottom element is preferably made of a soft material such as quilting made of cloth and urethane foam.

For upper layer shoes such as shoes or regular shoe shoes, it is better to use something a little harder. 2 indicates the upper element. In this,
3 is the upper element, which is formed to a size that can wrap around the front half of the foot. 4 is a heel, which is formed so as to surround the rear half of the foot. The upper element 2 is preferably made of a flexible material such as a soft leather such as buckskin, ordinary cloth, or a quilted cloth and cotton. Further, the upper element 2 is preferably formed of a material that prevents heat from escaping to the outside. The peripheral edge 2a of the upper element 20 is joined to the peripheral edge 1a of the bottom element 1 by any joining means such as sewing or gluing. A second upper element 5 is placed along the inside of the upper element 3, and its edge 5a is joined to the peripheral edge 1a of the bottom element 10 together with the peripheral edge 2a. 6 indicates the insertion space in the front half of the foot. Reference numeral 7 designates a heating element housing portion formed between the upper element 3- and the second upper element 5. The storage portion 7 is formed in a size that extends to the toe portion of the footwear as shown in FIG. 3, and extends to the bottom element 1 at the left and right edges of the footwear as shown in FIG. 8
indicates the entrance and exit of the heating element.

Reference numeral 9 is a string for opening and closing the access port, and is attached to the upper element 3. Next, IO indicates a heating element. This heating element is constructed by enclosing a fluid heating material inside a bag 11.

The fluid heat generating material 12 is primarily an iron oxide based heat generating material, and is formed in powder form.

When using the footwear configured as described above, the heating element IO is inserted into the storage part 7 with the string 9 loosened and the opening 8 widened, and the string 9 is tied to shorten the opening 8. In this state, the footwear is worn with the front half of the foot located within the insertion space 6, as is well known.

In the above usage conditions, the heat emitted from the heating element 10 warms the front half of the foot within the space 6, providing a comfortable feeling when walking.

In the above case, in particular, the front edge 11 of the bag 11 in the heating element 10
a reaches the front edge of the storage portion 7 and is located in front of the toe (see FIG. 3), and the left and right edges 11b.

11b reaches the left and right edges of the storage section 7 and is located on both the left and right sides of the front half of the foot (see Figure 4), and the heat generating material 12 inside the bag
As shown in FIGS. 3 and 4, due to its own weight, it is located within the edges 11a and llb of the bag 11 in front of the toes or in the left and right positions of the front half of the foot. Therefore, the edges of the bag Due to a lot of heat from the heat generating material located inside the
The toes of the foot can be effectively heated from the front, and the front half of the foot can be effectively heated from both the left and right sides. Further, the heat generated from the heat generating material present in the above-mentioned ridge passes through the bag and is transmitted to the upper part of the instep of the foot, thereby warming the middle part of the foot in that part. Therefore, the front half of the foot is warmed from the left and right sides, the front of the toes, and the upper part of the foot, making it extremely comfortable.

Furthermore, in the above state, since the heat generating member 12 is positioned in the above state, the heat generating element 10 is difficult to shift its position within the storage section 7, and as a result, the above comfortable heating state can be stably maintained. .

In addition, when used as described above, the heating element generates heat by applying an appropriate amount of rubbing force, so it is possible to apply a rubbing force to the heating element before storing it in the storage section 7 as described above.
Even if you do not do such a thing, it is possible to generate heat for the following reasons.

That is, if the heating element 10 is put in the storage part 7 and used, and you walk around the room with the footwear on, the -
The instep part is repeatedly bent and extended with each step, and as a result, the storage section 7
A moderate kneading effect is given to the heating element 10 inside. Therefore, the massaging effect can accelerate the heat generation of the heating element 10. If your footwear is home socks, you can not only clean, wash, etc. while wearing them, but also sit under the kotatsu or sit straight on the floor. There is no discomfort and you can get an extremely good feeling of use. Moreover, the above-mentioned footwear can be comfortably used for office work at a desk, dressmaking, studying, etc.

Next, FIGS. 5 and 6 showing different embodiments of the present application will be described. This example shows an example in which the heating element insertion/removal opening 8e is provided in the center of the upper element 3e, and a fastener 13 is provided therein to allow the insertion/extraction opening 8e to be freely opened and closed. It should be noted that parts that are functionally the same or equivalent to those in the previous figure are given the same reference numerals as in the previous figure with an alpha bent e, and redundant explanations are omitted.

(Effects of the Invention) As described above, in the present invention, when the footwear is worn, the front half of the foot can be warmed by the heat generated by the heating element 10 placed in the heating element storage section 7, It has the advantage of being comfortable to use.
