Description

Calibration insole set and its provision {{Insole set For Orthotics, Method For Providing The Insole}

The present invention relates to a shoe insole providing method and apparatus therefor, more specifically, to create a 3D stereoscopic data about the sole by scanning the sole using a 3D laser scanner 3D model of the standardized product suitable for the result data It relates to a calibration insole set using a 3D laser scanner for selecting and a method of providing the same.

Conventionally, as a method of manufacturing a customized shoe insole, it has been common to manufacture a shoe insole using a footprinter foam box. Here, the method using the foam box is a method of applying pressure to the foam box by applying pressure to the foam box, filling the plaster with the plaster mold by engraving the foot shape with an engraved pattern, removing the foam box, polishing the plaster, A plastic plate material heated in a container is placed on the foot-shaped frame, and then a product of a shoe insoles shape is produced by vacuum molding. The finished product is further hand-knitted again, and then various stiffeners are further adhered to complete the shoe insole production process using the foam box method. However, since this method requires manual work in the manufacturing process, it is difficult to keep the foot-shaped frame made of gypsum as well as cumbersome. Therefore, after the passage of time, the same person repeats the above- There is a problem to be done. Therefore, it takes a long period of time to manufacture the insole suitable for the user's own foot, and the cost is high, so that it has not been popularized.

Recently, the sole is scanned three-dimensionally using a 3D foot scanner or a 3D camera, and the measured foot data is modeled in an insole shape using a program for shoe insoles, In the control milling machine, a file for automatic machining is created so that the basic skeleton can be automatically machined, and the insole is machined by machining the modeled shape.

However, since such a general 3D foot scanner uses a method of measuring the shape of the sole using a certain pattern that is a standard of the camera and measurement, and a method of measuring the shape of the sole using a laser instead of a constant pattern, Most equipment that measures shape is expensive. In addition, since data for machining is made using software corresponding to the equipment using the data of the foot-shaped feet, and then the machining data is processed using the NC machine, the customer directly receives the shoe insole product There is a problem that it takes a lot of time.

In addition, in the case of existing products, in order to obtain the shape of the soles of the feet, it is necessary to take the footprints directly on the footprint plate with the bare foot ink, and then produce the product suitable for the customer on the basis thereof, And then supplied the products to customers. Even in this case, errors may occur depending on the pressing pressure of the sole, and it is necessary to process the shape of the three-dimensional sole through the data printed on the flat paper, so that it is difficult to supply the shoes insole suitable for the customer.

Japanese Unexamined Patent Application Publication No. 2000-509139 discloses a method and system for measuring the shape of an object related to a shoe. In this device, only the external shape of the foot is measured three-dimensionally, It is impossible to provide a means for measuring the shape of the shoes.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Orthodontic insole set of the present invention is manufactured by using a plurality of injection molds processed by various shapes and sizes. Each insole is provided in pairs for left and right foot and a user can be provided with a single insole with the same shape and size.

As shown in FIGS. 1 and 2, the insole 1 is formed by injection molding a synthetic resin such as polypropylene into a thickness of 1.5 mm or more to give a cushion to the insole main body 3 having rigidity, 3 are covered with the cushion cover paper 5. The insole body (3) includes an arch support part (7) capable of supporting the arch of the foot and a heel support part (9) capable of supporting and supporting the heel. The heel receiving portion 9 has a side wall 11 having a height of 5 to 15 mm.

A buffer hole 13 having a diameter of 15 to 30 mm is formed in the intermediate portion of the insole main body 3 and at the portion of the inferior cruciate bone so as not to be hit by the insole main body 3 having a hardened bone. A circular cushion material (15) can be fitted in the buffer hole (13). The length (K) of the insole body (3) can not reach the joints between the metatarsophalangeal muscles and the non-musculoskeletal joints. That is, the length K of the insole body 3 is equal to the distance from the heel to the lower point of the metatarsal metacarpal, in order to prevent the front part of the foot, which is first contacted with the ground, against the rigid insole body 3 to cause pain It is consideration.

Insole body (3), the main body of the insole (1) is determined by the shape and size of the three elements. These three elements are the heel width (W), the reference length (L), which is part of the foot, and the highest depth (D) of the arch. Reference length (L) is the distance between the first point (P1) where the leading end of the metatarsal bone connected to the base bone fracture and the bottom point (LP) which is the end of the heel (see Fig. 7).
These three variables can be summarized in the following table. The user measures his foot with a laser scanner and compares the data with the data stored inside the computer connected to the scanner. You can take it out of the insole set and immediately check the changed posture according to the user's foot.

\ Length (L)
Width (W) \ L1 L2 L3 L4 W1 Depth (D) D1 Depth (D) D1 Depth (D) D1 Depth (D) D1 D2 D2 D2 D2 D3 D3 D3 D3 W2 Depth (D) D1 Depth (D) D1 Depth (D) D1 Depth (D) D1 D2 D2 D2 D2 D3 D3 D3 D3 W3 Depth (D) D1 Depth (D) D1 Depth (D) D1 Depth (D) D1 D2 D2 D2 D2 D3 D3 D3 D3 W4 Depth (D) D1 Depth (D) D1 Depth (D) D1 Depth (D) D1 D2 D2 D2 D2 D3 D3 D3 D3

The priority factors to be considered in the table are the length (L) and the width (W). However, it is possible to change the basic element by changing the positions of the length (L), the width (W) and the depth (D) as necessary. However, it is preferable to set the order of the length L, the width W and the depth D in order.

The above table shows that a total of 48 kinds of insole can be provided. However, if the expansion is made in the same way, it is possible to prepare much more kinds of insole.

The following describes a method of determining an insole of a specific size and a photographing apparatus used therefor. First, a photographing apparatus will be described with reference to Figs. 3 to 6. Fig. The photographing apparatus 17 of the present invention is constituted by a foot moving part 17a and a posture photographing part 17b.

The reference length L, the width W, and the depth D of some sections of the user's foot are determined using the photographing apparatus 17. The photographing apparatus 17 obtains a stereoscopic image of the foot, and calculates the stereoscopic image according to a pre-input program, thereby providing a result value. The photographing apparatus 17 selects an insole having an appropriate size from the above table based on the resultant value.

The foot photographing unit 17a uses a linear laser and a camera. Since it is a generalized technique to obtain a photographing mode and stereoscopic image data therefrom, a detailed description thereof will be omitted.

The foot photographing section 17a basically comprises a case 23 in the form of a chamber with a foot inlet 21 provided above the face plate 19 at a height that allows a user sitting on a chair to extend his / And a scanner (25) fixedly installed inside the case (23). The upper end of the scanner 25 is supported by the rear plate 27 of the case 23 and the lower end of the scanner 25 is supported by the intermediate plate 29 of the case. When the user is sitting on a chair, his / her foot is inserted into the foot inlet 21 to be adjacent to the scanner 25, and in this state, the user comes to take a picture. Since the case 23 is sized to accommodate one side of the foot, the user must shoot the foot alternately. In some cases, the case 23 may have a structure capable of shooting both feet at the same time.

The foot insertion slot 21 is provided with a curtain 31, and the case is kept in a closed room state. Therefore, the scanner 25 can obtain accurate data without being disturbed by an external element.

According to the embodiment of the present invention, the ventilation fan 33 for venting the air inside the case 23 to the outside can be installed above the side plate or the back plate 27 of the case 23. According to another embodiment of the present invention, an infrared lamp 35 may be further installed inside the case 23. This infrared lamp 35 can be used as a means for warming the feet, giving the user comfort, and for drying and sterilizing the feet for the time required for shooting.

Hereinafter, the scanner 25 fixedly installed in the case 23 in an inclined manner will be described.

Various components are mounted on a rectangular base plate 37 which is at least longer than the total length of the feet. The guide rods 39 are installed on the base plate 37 by the support block 41. The support blocks 41 are provided at both ends of the guide rods 39, respectively. The movable base 43 is installed to be movable along the guide rod 39 by being engaged with the guide rod 39.

The rotary belt 45 in the form of a timing belt is installed side by side with the guide rod 39 so as to be rotatable in an endless track manner. And a moving stand 43 is connected to one point of the rotating belt 45. [ The drive motor 47, which is a stepping motor, is for rotating the rotary belt 45. Therefore, the movable base 43 is actuated in the forward and backward directions along the guide bar 39 by the rotational drive of the drive motor 47. A laser generator 49 and a camera 51 are mounted on a moving base 43. The cover 53 is fixed to the base plate 37 by a screw, and has a transparent portion 55 through which light can pass in the longitudinal direction.

The luminescent lens 49a of the laser generator 49 is mounted on a projection 57 formed obliquely and protruding from the moving table 43 so that the laser beam is emitted upward with an inclination. The camera 51 may be installed in a vertical direction so as to photograph the upper portion of the base plate 37. PCs 59 and PC for data calculation and control can be installed between the bottom plate 61 and the middle plate 29 of the case 23. [

The posture photographing unit 17b shown in Fig. 8 includes a tread plate 63 on which a user can place his / her foot at a predetermined point; A side camera 65 installed at a side of the tread plate 63 and capable of photographing a side of the individual standing on the tread 63; Two rear cameras (67, 68) provided behind the tread plate (63) and capable of photographing the heels of the individual, respectively; And a front camera 69 installed in front of the tread plate 63 and capable of photographing the front whole body of the individual. The posture cameras 65, 67, 68, and 69 may be connected to the PC (PC) at the same time to enable data communication.

The posture cameras 65, 67, 68, and 69 capture the posture of the body corresponding to Figs. 9 to 11 to obtain the data before wearing the insole, repeatedly photographs the selected insole, and obtains data after wearing the insole .

A method or technology for obtaining a three-dimensional image using a laser and a camera is known, and therefore, a detailed description thereof will be omitted. However, a method for determining the insol based on the acquired data will be described with reference to FIG.

As mentioned, there are three factors that determine the shape and size of the foot, which is the reference length (L), width (W) and depth (D) of some sections of the foot. Hereinafter, a method for determining these will be described.

When you step on the ground, you will see the first touching point on the ground, one of which is located on the big toe side (P1, specifically called the 'First Metatasal Point') and the other is the second point on the heel side )to be. The first point P1 is where the distal end of the metatarsophalange is connected, and the second point P2 is where the calcaneus is located. The second point P2 is defined as the center point CP of the circle C passing through the outer tangential line T1 of the foot and the first outer contact point 1TP contacting the heel and the lower end point LP of the heel end, The point at which the straight line PL passing the center point CP of the circle and the first outer contact point 1TP intersects with the inner surface of the foot heel side is defined as the second inner contact point 1T'P. The distance between the first outer contact 1TP and the second inner contact 1TP becomes the width W. [ The vertical distance between the lower end point LP and the first point P1 is defined as the length L.

On the other hand, a point at which the horizontal line drawn at the deepest point DP at the deepest part of the foot and the vertical line VL drawn toward the toe from the first inner contact point 1T'P intersect is defined as an intersection point QP, (Depth in the direction perpendicular to the drawing) of the arch in the depth direction (QP) is defined as the depth (D, see Fig. 1).

Another aspect of the invention is a method of providing a calibration insole. The first step is preparing the calibration insole set; The second step is to determine the shape and size of the individual's sole; The third step is to select one of the insoles and provide them to the individual. According to the present invention, in the second step, the three-dimensional structure of the sole is grasped by using the above-described photographing apparatus. The photographing apparatus includes a linear laser and a scanner employing a camera.

In the third step, the determination method for determining the insolence can be performed by the method described above. On the other hand, the shapes and sizes of the left and right feet may be different, which is a common phenomenon. It is also necessary to determine which foot is to be in-soled on the basis of a normal user except for a particular trauma or congenital anomaly. This is because it is preferable that the insole of the left and right legs is used as an orthosis insole as long as there is no particular situation. In any case, when the sizes of the left and right legs are slightly different, the present inventor proposes that the shorter one is given priority over the length L, the larger one is given priority over the width W, and the lower priority is given to the depth D .

The set of insole is as described above, and usually consists of 150 to 300 kinds of unit insole. It is needless to say that the number of types can be increased as needed. It is confirmed by the inventor's experiment that there is no difficulty in applying to the feet of modern people when the insole is made up of 190 kinds. The steps 2 and 3 are all described above, so the repetitive explanation is omitted.

According to a feature of the present invention, the method may further include a fourth step of photographing a change state of the body by photographing the posture of the individual wearing the insole selected from the insole set.

The fourth step is to place the user on the tread plate 63 as shown in Fig. 8, and then use the side camera 65, the rear camera 67, 68, and the front camera 69, The posture of the corresponding body is photographed to obtain the data before the insertion of the insole, and the selected insole is then worn and repeatedly photographed to obtain the data after wearing the insole. And compare the previous data with the subsequent data so that the corrected state of the user can be compared and confirmed. Figs. 9 to 12 show a comparison between data (left side) before wear of the insoles and data (right side) after wear, and it is easy to compare how much the posture has changed due to wearing of the insole. The rear cameras 67 and 68 are provided for each of the heels so that the heels can be accurately photographed.

According to an embodiment of the present invention, the personal data obtained by scanning the sole of the individual is overlapped with the insole data for the insole stored in the computer and displayed on the monitor at the same time; The method may further include a fifth step of replacing the insole data and overlapping the personal data to find an optimal state. In this case, an image as shown in FIG. 2 can be obtained on the monitor. In this state, the insole or the insole main body 3 can be changed in real time to a different size, so that the insole that matches the foot of the user can be found. That is, it is possible to find and provide a more accurate size before actually worn in the selected insole body 3. Referring to FIG. 2, the image of the individual's footprints is personal data (PD), and the image of the insole is the insole data (ID).

Although the embodiments of the present invention have been described above, various modifications may be made by those skilled in the art. Therefore, it should be understood that the present invention should not be construed as being limited to the above embodiments, but should be construed in accordance with the following claims. Each of the above embodiments may be used in various combinations as needed, and these combinations are included in the scope of the present invention even if not mentioned above.
