Abstract

The present invention comprises a system for measuring the correct size of a shoe. In particular, the system comprises a sensor (1) which is arranged at the tip of the shoe at the level of the toe or forefinger and comprises a light-emitting diode (2), preferably a light signal, when said toe touches the sensor. ). In this way, it is always possible to check that the shoe size is correct, which is especially important for children who can hardly say that when the shoe no longer fits the foot size.

Description

[0001]
(Technical field)
The invention relates to the technical field of the production of footwear, in particular accessories connected or attached to the footwear, the invention making it possible to accurately measure the correct length of shoes for a foot.
[0002]
Everyone knows the drawbacks of wearing shoes that do not fit the size of their feet. Short shoes, in which the toe or forefinger of the toe inside the shoe touches the upper of the shoe at the tip of the shoe, can cause malformations or illnesses similar to hallux valgus or toenail invading the meat. The toe or index finger generally requires at least 1 cm of space to walk properly.
[0003]
(Background technology)
Currently, there is only one system that checks if the size of the shoe fits the foot. It is sufficient to press the upper of the shoe at the tip of the shoe to test for contact with the toe or index finger of the foot. Obviously, this is an empirical method, especially for children, which is not very functional.
[0004]
Currently, no shoe can confirm the correct size at the time of purchase, and therefore the purchased shoe often becomes uncomfortable after a while and cannot be worn because it is too short.
Children can't tell their parents 1) when buying shoes that they're the right size when buying shoes, 2) they grow fast, and their children's shoes get smaller quickly, but they recognize that Do not suffer from this problem for two reasons.
[0005]
In contrast, the purpose of the system of the present invention is to establish the correct size of the shoe in a simple and reliable manner without adding a great deal of cost to the price of the original product and without being noticeable by the wearer. Is to make it possible.
[0006]
It is an object of the present invention to avoid the above difficulties, as will be better shown in the following description.
[0007]
(Disclosure of the Invention)
Reduced to essential structure, and referring to the accompanying drawings, the system of the present invention for measuring the correct size of a shoe for a foot on the shoe,
Means for detecting the position of the thumb or forefinger of the foot by a sensor (1) arranged at the tip of the sole;
Means for being turned on when the sensor is actuated with said finger, to indicate contact of the sensor with the toe or index finger by means of a light emitting diode (2) or other sound or visual notification;
Means for connecting the sensor with a light emitting diode or other audible or visual notification system by means of an electric circuit (4) powered by a battery (3);
including.
[0008]
Preferably, the present system for measuring the appropriate size of a shoe is formed by a light emitting diode, a battery, and a sensor mounted on the inside of the shoe and connected to each other, and the toe or forefinger of the toe of the shoe at the tip of the shoe. In order to signal when too close to the camera, a finger activates the sensor in this case, turning on a light emitting diode, which means that the shoe is too short.
[0009]
Preferably, a sensor is mounted at the point on the tip of the sole where the contact of the toe or index finger is poor and said shoe is found to be too short. In this way, when the finger touches the sensor, it is notified that the position is bad.
[0010]
Preferably, the sensor is mounted beyond the point where the thumb or forefinger of the toe can move forward about 1 cm during walking, i.e. very close to the upper of the shoe.
When contacting the sensor, the toe or forefinger of the toe is in a "dangerous area", that is, less than 1 cm from the instep of the shoe, so the sensor is activated and a light emitting diode indicates that the shoe is too short.
[0011]
Preferably, the sensor is mounted at the height of the toe or index finger of the foot, about 1 cm from the upper of the shoe, ie the minimum space required to walk. Preferably, the alerting system is mounted on the heel or other location so as not to detract from the beauty of the shoe, and alerts and glows when the toe or index finger is about 1 cm from the tip of the shoe.
[0012]
Preferably, the notification issued after activating the sensor with the toes may be a sound to notify the outside when the shoe is too short, or a visual light consisting of light emitting diodes visible from the outside of the shoe. May be something.
Such a system has the advantage of alerting the wearer when the shoe is initially the right size and then shortens, which is especially important for children.
[0013]
Referring to FIG. 3, the entire system, preferably consisting of a sensor, a battery and a light emitting diode, is housed inside the sole, with the insole serving as a cover.
[0014]
Referring to FIG. 4, preferably, the battery and light emitting diode are mounted inside the sole, and the sensors and associated connections are provided under the insole. Referring to FIG. 5, preferably, the entire system consisting of sensors, batteries, light emitting diodes and connections is housed in an insole inserted into the shoe.
[Brief description of the drawings]
FIG. 1 shows a schematic diagram of an electric circuit mounted on a sole for operating the system of the invention. 1 shows a sensor (1) provided at the level of the thumb or forefinger of a toe and acting as a switch. Once the sensor is activated with the toe, the light emitting diode (2) provided on the heel or elsewhere is turned on. This system works with a circuit (4) including a battery (3) and a simple light emitting diode.
FIG. 2 shows an electrical circuit of the system of FIG.
FIG. 3 shows a shoe in which the system is located entirely within the sole and the insole is the cover.
FIG. 4 shows an exploded view of a shoe in which sensors and connections are provided under an insole and a battery and light emitting diodes are housed inside the sole.
FIG. 5 shows a shoe insole housing all of the system.
FIG. 6 shows the side of the shoe with the system provided in the sole.
FIG. 7 better illustrates the utility of the system to prevent the foot from touching the shoe upper at the tip of the shoe and the resulting problem, showing the same parts as in FIG. 6 with the foot included.
