Description

The method of shoe correction relates to shoe manufacturing, namely, to machines, tools, equipment and methods for manufacturing or repairing shoes. It can be used in the manufacture of individual shoe pads for the production of footwear, but the main direction is the use of the described technology, for the correction of ready-made, both new and used shoes, in order to achieve maximum comfort and convenience during its operation. The method of correction of shoes allows you to bring ready-made shoes in exact compliance with the foot, which in turn eliminates negative health effects: squeezing of blood vessels, injuries of joints, poor posture, etc.

The footwear made in the industrial way, is made on standard technology, without taking into account features of a structure of foot. But the foot of each person is individual. In the past, shoes were usually sewn according to the foot of each individual. However, at present, due to population growth and the development of industrialization, only industrial-made footwear is available to the greatest number of people, which is mass production and, of course, does not take into account all the individual characteristics of the foot.

There is a method of manufacturing individual shoe pads patent RU 2596517 C2. This invention has several disadvantages. The complexity of the devices, technologies, equipment. The presence of complex software. The need for a specialist (specialists) who have a good knowledge of computer technology, technology, knowledge of special programs and able to put them into practice, skills to work with strain gauges, etc. This need in turn will lead to a significant increase in the cost of the final individual product. The use of this technology is currently inappropriate.

The analogy of the final task to correct the user's shoe and bring it in line with the foot, is traced in the invention RU 2236806 C2. The disadvantage of the invention in the impossibility with extreme precision to bring shoes in full compliance with all the individual characteristics of the foot. This occurs in connection with the obligatory errors arising from the impossibility of creating an exact copy of the foot by a correction device.

Summary of Invention

The task, which the shoe correction method is aimed to solve, is the most accurate shoe adjustment according to the consumer’s foot.

This task will be solved by the method of correction and bringing the consumer's shoes in full compliance with his foot, taking into account its individual characteristics, providing for the manufacture of an individual volume copy of the foot with its subsequent use as an element of correction. To obtain a volume copy, the foot is briefly placed in a container filled with an impression material, preferably based on alginates. Alginate-based impression masses are distinguished by their high elasticity, flexibility, and biological compatibility. The residence time of the foot in the impression mass is established, depending on the characteristics of a given mass, namely, a time interval corresponding to the gelation of the mass. Characterization of gelation is indicated on the packaging or in the passport of this product, and is a few minutes, which in turn saves the time of the consumer. Previously foot is corrected by an elastic toe. In the case of a wide front part of the shoe, the elastic toe, when placing the foot in the dental impression mass, is optional. In the container with the dental impression mass, the foot is, when fully set on the plane, preferably in a strictly horizontal position. The pressure of the entire body weight should be proportional to both feet of the consumer. When the foot is removed from the container, a cavity will remain in the impression mass, which will practically correspond to the foot of the consumer. After gelling the impression mass, we fill the cavity with a material that has the property of polymerization to adopt an appropriate density, preferably based on polyester or epoxy resins. At present, these materials are represented by a fairly wide range of characteristics. After polymerization of the material, we remove the outer layer of the impression material and as a result we obtain a volume copy of the foot of a corresponding density, which we later use as an element of shoe correction. We separate the toe-beam and heel part from the volume copy of the foot, for use directly in the correction of shoes. On the plane of the toe-beam part of the volume copy of the foot, for the convenience of removal, set the grip. We measure the parameters of the remaining element of the gelenochnoy part of a volume copy of the foot. According to the measurements, we make a spacer. It is possible to manufacture an element based on the threaded connections of the sock-beam and heel part of the volume copy of the foot, with the function of thrust. We process the outer and inner surfaces of the adjustable footwear with a tool for stretching the top of the shoe. This tool is currently also widely represented. We insert the sock-beam and heel parts of the volume copy of the foot into adjustable shoes, having previously placed the volume copy of the socks-beam part of the foot in a sheath of low-pressure polyethylene with a thickness of 35-40 microns. Lathing with the manufactured spacer at a distance equal to the withdrawn gelenochnoy part of the bulk copy of the foot. After the time required for making the shoes of the required shape, we remove the spacer part, remove the parts of the volume copy of the foot.

The achieved technical result of shoe correction is to give the consumer’s shoe full compliance with his foot, using an individual volume copy of the consumer’s foot, which ultimately provides the consumer with maximum comfort during operation.

The technical result of the method of correction of shoes, is an economical achievement of full compliance of the shoes with the foot of the consumer.
