Description

Foot size measuring device and online sales method of shoes using the same

The present invention relates to an apparatus for measuring a foot size and a method of selling shoes using the same, and in particular, an apparatus for measuring a foot size that accurately measures the size of a foot with a non-powered measuring apparatus and recommends and sells suitable shoes online. And it relates to an online sales method of shoes using the same.

Since humans have been walking upright, shoes have been an important piece of equipment. It can be seen as a path that transmits the force (gravity) of the ground as kinetic energy.

Shoes of the same model and the same size are slightly different in height, width, and shape. Even a person's feet are different on both sides. Not only the size, but also the arch height and flexibility are different.

Therefore, if you wear shoes that do not fit your feet, it can cause ankle ligament sprains, plantar fasciitis, Achilles tendinitis, and various diseases caused by abnormal alignment of the knee, hip joint, pelvis, and spine.

Also, feet with high arches have a narrow contact area with the floor. There is little pressure distribution, so you may feel tired, and your feet may be thrown outward. Conversely, a foot with a low arch shifts the weight inward, which puts pressure on the inner joints of the ankle and knee.

Therefore, it is beneficial not only for foot health but also for overall health to ensure that customers purchase shoes that are optimized for their feet. For example, if the arch is high, the floor contact area should be widened through the insole of the shoe. A well-fitted insole supports the arch and heel, makes walking easier, aids in body alignment, and increases safety.

On the other hand, in the "apparatus and method for measuring foot size" of the conventional Korean Patent No. 10-2030440, a horizontal guide line extending in a first direction crosses the horizontal guide line perpendicularly to the horizontal guide line, and a second direction perpendicular to the first direction Although a technique for photographing a user's foot through a vertical guide line extending in two directions and measuring the size of the user's foot by analyzing the photographed picture is disclosed, it must be provided with an image photographing means such as a camera and , there is a problem that only a flat size can be measured. That is, if the camera is not provided, it is a useless technique, and there is a problem in that it is not possible to reflect detailed parts such as the shape of the arch or the height of the instep.

1 is a flowchart illustrating a method of selling shoes online using the device for measuring a foot size of the present invention.

First, a preparation step (S10) of preparing user's foot information including corresponding points indicating the shape of the sole of the foot and the three-dimensional shape of the foot is performed.

The foot size measuring device of the present invention is used to find corresponding points representing the three-dimensional shape of the foot and the sole of the foot.

2, 3 and 4 are a side longitudinal sectional view, a front longitudinal sectional view, and a perspective view, respectively, showing the foot size measuring device of the present invention.

As shown in FIGS. 2 to 4 , a plurality of sliding holes 110 are formed at regular intervals on four side surfaces of the measuring box 100 , and the upper surface is opened, and the sliding hole 101 between the four legs 120 . is formed.

The thickness of the measuring box 100 is preferably thick enough to be firmly fixed after the sliding stick 200 is inserted.

The larger the number of sliding holes 110, the more accurate measurement is possible, but since the input process after measurement becomes complicated in the present invention, 16 short sides and 16 long sides of the rectangular measuring box 100 are sufficient for realizing a three-dimensional image in the present invention. 32, 96 sliding holes 110 were formed in a total of 4 sides.

The measurement is prepared by inserting the foot into the open upper surface. And four legs 120 are formed to support the measurement box 100 and at the same time, it is good to insert the sliding panels 300a and 300b in tight contact between the sliding holes 101 generated between the legs 120.

The sliding panels 300a and 300b are preferably two short ones and two long ones so that the measuring box 100 exactly matches the sliding ball 101 when the measuring box 100 has a rectangular shape.

And, it is preferable that the sliding panels 300a and 300b are marked with scales on the upper surface in the longitudinal direction, and the sliding grooves 301a and 301b are formed on both sides in the longitudinal direction for close contact. Therefore, the sliding protrusion 121 is formed in the middle of the four legs 120 so that the sliding grooves 301a and 301b are accurately fitted to maximize the adhesion and fixing power.

On the other hand, the sliding stick 200 has a pointed tip 201 formed at one end, a number is written on the surface 202 of the other end, a scale is marked on the upper surface in the longitudinal direction, and is inserted into the sliding hole 110 . The scales are scales indicating the inserted depth when the sliding panels 300a and 300b or the sliding stick 200 are inserted and touch the surface of the foot.

And the number on the surface 202 of the other end of the sliding stick 200 is to confirm the position of the stick and to write it in order on the future numerical input platform.

That is, after placing the foot in the measurement box 100, the sliding stick 200 and the sliding panel 300a, 300b are measured and inputted into the numerical input platform to implement a three-dimensional image based on the insertion depth. to measure the size.

Such a measuring device does not require a separate power source, does not require an expensive laser distance measurement device, a camera, an ultrasound device, etc., and furthermore, there is an advantageous effect that there is no inconvenience of calculating the scale by photographing the size of the foot with a camera. That is, by reading the scale of the inserted depth of the sliding stick 200 and the sliding panels 300a, 300b, and inputting only the numerical input platform to a computer or other terminal without a camera, a three-dimensional foot shape can be realized with simple calculation. will be.

5 is a diagram illustrating the concept of implementing a three-dimensional image using corresponding points in the foot size measuring device of the present invention.

Referring to FIG. 2 together, the four left sliding sticks 200 and the four right sliding sticks 200 of FIG. 2 belong to the same column. That is, referring to FIG. 4 , it means four sliding sticks 200 inserted into the sliding holes 110 in the same row among a total of 16 sliding holes 110 on the left side of the measurement box 100 . Because they are in the same row, they share the same longitudinal section of the foot.

As shown in FIG. 2 , a scale is read by measuring a depth f1 into which the sliding stick 200 at the bottom left is inserted and a depth f2 into which the sliding stick 200 directly above is inserted. In FIG. 2 , the insertion depth of a total of eight sliding sticks 200 and the depths d1 and d2 into which the two sliding panels 300a and 300b are inserted can be read.

In the same manner, in FIG. 3 , the insertion depth of the eight sliding sticks 200 and the depths d3 and d4 into which the two sliding panels 300a and 300b are inserted can be read.

In the end, the value obtained by subtracting d1+d2 from the total length L of the measurement box 100 becomes the length of the foot, and the value obtained by subtracting d3+d from the width W of the measurement box 100 becomes the width of the foot.

In addition, by reading the depth of a total of 96 sliding sticks 200 inserted in four directions, it is possible to measure the corresponding point where the pointed tip 201 of the sliding stick 200 meets the surface of the foot. These corresponding points are expressed in three dimensions in FIG. 5 .

That is, eight corresponding points (p1 to p8) of a column located in one longitudinal section in the three-dimensional rectangular coordinate system of the xyz axis are indicated. This means the corresponding point where the eight sliding sticks 200 of FIG. 2 touch the surface of the foot. If the coordinates of p1 are (10, 4, 1), the other coordinates of p2 to p8 have only different x and z values, and all of them have a y value of 4.

Meanwhile, a value between p1 and p2 may be newly expressed by an average value operation. That is, if p1 is (10, 4, 1) and p2 is (8, 4, 1.5), the average value a1 is (9, which is ((10+8)/2, 4, (1+1.5)/2). 4, 1.25). Again, if the dots are densely drawn in a way that takes the average value between p1 and a1, as a result, a three-dimensional foot can be realized. a2 and a3 are also average values of p2 and p3 and average values of p3 and p4.

The present embodiment discloses a numerical input platform capable of inputting the shape of the sole, the insertion depth of the four sliding panels 300a and 300b, and the insertion depth of the 96 sliding sticks 200 . However, since the insertion depth of the sliding panels 300a and 300b cannot be greater than the insertion depth of the sliding stick 200, the number of input values of the sliding stick 200 can be reduced than 96 in consideration of this. That is, only the insertion depth of the sliding stick 200 inserted deeper than the insertion depth of the sliding panels 300a and 300b should be taken into consideration when inputting a numerical value.

Next, the server 600 performs a sampling step (S30) of taking corresponding points according to the foot information in a three-dimensional space.

As shown in Fig. 5, the corresponding point is taken in a three-dimensional space. These can be seen as discrete values.

Therefore, the server 600 proceeds with the implementation step (S40) of implementing the shape of the foot as a three-dimensional image by using the foot information. As described above, if enough points are taken using the average value, as a result, the point becomes a line, and the line becomes a surface to obtain a three-dimensional shape that appears as a three-dimensional surface.

Next, a recommendation step (S50) of searching for shoes suitable for the three-dimensional image in the database 610 and displaying the shoes on the user terminal 700 may be performed.
