Description

[Technical field]

[0001] This invention relates to a pair of sandals that are structurally strong and beautiful, as well as practical to use. [Background technology]

[0002] Modern people spend a lot of time wearing shoes, which can lead to poor posture and imbalance of the body's center of gravity, which is thought to cause a variety of health problems.

[0003] It has been noted that wearing sandals without a heel can improve posture and the body's center of gravity balance.

[0004] There are patent documents 1 to 3 that focus on such health-promoting effects and are related to the configuration of half sandals. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2009-225919 A [Patent Document 2] Registered Utility Model No. 3188536 [Patent Document 3] Registered Utility Model No. 3249011 Summary of the Invention [Problem to be solved by the invention]

[0006] Conventional ashihanzori sandals were mostly handmade by amateurs, and therefore had a simple structure and lacked durability.

[0007] For this reason, the foot sandals have the disadvantage of not being able to fully utilize their original functions. The purpose of this invention is to solve these problems. [Means for solving the problem]

[0008] In this invention, the conventional four-core structure is improved to a six-core structure by weaving a single core rope in a spiral arrangement, which serves as the base. In addition, by passing the core rope through the main body in a spiral from the outside to the inside after the main body is braided, a reinforced structure with 10 cores passing through is realized. In addition, the core rope is switched between right-handed and left-handed to clearly distinguish between left and right, and the front part is positioned closer to the thumb to make it even easier to distinguish between left and right. In addition, the knitting is more detailed and thinner than in conventional products, strengthening the structure and preventing the shape from changing. In addition, the straps are designed to be attached to the outside of the sandal body, and by storing the ends of the straps on the outside of the sandal body, the previous discomfort of the knot of the strap rubbing against the sole of the foot is eliminated.This results in a flat sole and a comfortable fit. Effect of the Invention

[0009] This invention improves the beauty and strength of ashihanzori compared to conventional products. It also promotes the adjustment of the center of gravity of the body and the formation of the arch of the foot, which are the original functions of ashihanzori, and as indoor shoes that provide a stretching effect just by wearing them, it will contribute to health promotion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] (Foot sandals body) A core rope (hereinafter referred to as the "core rope") of approximately 3.5 m is arranged in a spiral or circular fashion around multiple supports of the knitting table. For example, if there are four posts, you can wrap the core rope in the order of 2, 4, 1, 3, 2, 3 based on the post numbers (and vice versa for the other side). This will result in different finishes, making it easier to distinguish between left and right. Pull the center of the bottom and use your hands to fix starting point A (this is where you start knitting). Weave the rope in a plain weave manner, using six vertical core ropes arranged in a fan-shaped radiating pattern from starting point A as a base. Plain weaving is a weaving method in which the warp threads (vertical threads) and weft threads (horizontal threads) are alternately raised and lowered. In this device, the core rope is used as the warp thread, and the braided string that forms the main body of the half sandals (hereinafter referred to as the "main body") is used as the weft thread. The warp thread is made by weaving the braided cord, which serves as the weft, back and forth horizontally between the core ropes, weaving it in and out of the spaces between the core ropes. After passing the braided cord over the core rope, it is passed under the next core rope, and the braiding is continued by alternating up and down the rope. This allows the core rope and braid to cross perpendicularly, forming a uniform stitch. The size of the sandals is determined by measuring the length from the base of the big toe to the arch of the foot. When braiding is finished, remove the main body from the braiding table, then pull both ends of the core rope. After that, pull one of the two overlapping core ropes from starting point A and pull it toward the outside of the spiral to shape it. Cut off the core rope, leaving about 20cm from the main body. The remaining core rope is coiled into the main body. Finally, wrap the exposed core rope at the front end (toe side) and back end (arch side) with braided string, and tuck the remaining braided string into the main body, completing the main body of the sandals.

[0012] (Thong and front part) (Making the thong) The long, narrow strips of cloth (approximately 50-60cm long and 8-15cm wide) that will become the thongs are sewn together into a tube shape, and a nylon string is passed through the center without any gaps. This becomes the padding for the thongs. The length of this nylon string will determine the length of the thong, so adjust it to the desired length. For example, adjust it to about 20-30cm. Additionally, pass a piece of nylon string through the thong for attachment (approximately 60 cm).

[0013] (Attaching the thong) Fold the braided string used for attachment (approximately 40 cm) in half and bring both ends out from the back of the main body to the front. This string is wrapped around the thong and crossed over, then returned to the back of the body, then brought to the front once more, wrapped around the braided string previously wrapped around the thong, returned to the back, tied, and secured in place. The part that secures the thong to the main body is called the "maetsubo." Another benefit of this structure is that the connection between the thong and the front part is not fixed, allowing the front part to move left and right and be adjusted to fit the wearer's feet, and the use of nylon string for the padding means that the shoes dry quickly when washed.

[0014] (Location of the front yard) The front part connects the sandal body to the strap and is located between the big toe and index toe.

[0015] (Fixing the strap and the body) Pass the end of the thong from the back of the main body fixing position to the front. The body of the sandal is turned over, the thong is passed through the outermost weft stitches of the body, and tied tightly, with the excess thong being tucked inside the weft. After tying the thong to the main body, pass the nylon string that is threaded through the thong along the edge of the main body. This will firmly secure the thong and the main body of the shoe. Repeat the same procedure for the other end of the thong. Once both are secured in place, the foot sandals are complete. The knot of the thong may be reinforced by applying craft adhesive to it. EXAMPLES

[0016] Hereinafter, an embodiment will be described with reference to the accompanying drawings. Figures 1 to 6 show how to make the main body of the sandals.

[0017] FIG. 1 is a plan view of the front and back sides of the completed ashihanzori sandals.

[0018] FIG. 2 is a side view of the knitting stand used in production, and FIG. 3 is a plan view of the core ropes placed on the posts in preparation for production.

[0019] Starting from starting point 3A shown in Figure 3, we proceed with the plain weave as shown in Figure 4. After the desired size is reached, one of the two overlapping core ropes is pulled from starting point 3A and shaped toward the outside of the spiral.

[0020] Figure 5 shows how the core rope is arranged in a spiral shape inside the body of the sandals. The core rope is cut off leaving an appropriate length (for example, about 20 cm). Figure 6 shows how the cut core rope is placed inside the body. This results in a structure in which six vertical strands are used as the core at first, and four vertical strands pass through at the end, increasing the overall strength.

[0021] Make the nose piece. FIG. 7 is a side view of the thong with the nylon string for fixing passed through it before attachment.

[0022] Create the front basin. Figure 8 is a schematic diagram of the attachment of the thong and front part. The front part is the part that secures the thong and the main body of the glove, and is located between the big toe and the index toe. The braided string used for attachment (which will become the front part when completed) is folded in half, and both ends are brought out from the back of the main body to the front. This string is wrapped around the thong, crossed over, and then returned to the back of the main body. After that, it is brought out to the front again, wrapped around the braided string that was previously wrapped around the thong, and returned to the back to be secured. Furthermore, since the front part is simply wrapped around the thong, it can move from side to side. FIG. 9 is a side view of the completed front part (9B) and half sandals.

[0023] Fixing the thong to the body of the sandals. Figure 10 shows the position where the thong is fixed, with the end of the thong passing from the back side to the front side of the main body. Figure 11 shows how to turn the body upside down, wrap the thong around it, pull it out, and then store the excess thong on the outside of the body. FIG. 12 is a diagram showing the positions of the thong and the fixing string inside the main body.

[0024] FIG. 13 is a schematic diagram of the spiral on the underside of the sandals. [Explanation of symbols]
