Signal Vest

The utility model relates to protective clothing with reflective and luminous means of security, in particular, to a vest with signal elements, mainly intended to be worn by children at night, to be more visible to drivers.

Known vests containing back and chest, interconnected by shoulder and side sections and provided with reflective and fluorescent signal elements. Such signal vests are described, for example, in patent documents RU 2909 U1 and RU 35193 U1.

However, such vests with light-reflecting elements are clearly visible to drivers only when the headlights illuminate parts of the vest, but at a different angle of view they may not be noticeable enough. At the same time, fluorescent signal elements have a low luminosity, which also decreases with time. In addition, the carrier of such a vest may not notice the light of the approaching car and not step aside, passing the car. It should also be noted that such vests, due to the presence of the breast and back, are adapted to be worn only directly on top of the clothes, but not on top of a backpack or briefcase, which can be worn, in particular, on the child.

The closest to the utility model is a signal vest, presented in the online store at https://ru.aliexpress.com/item/48/32921069717.html?spm=a2g0v.10010108.1000016%2FB.1.39862058ddt2aC. This vest contains a case made of waterproof textile material with attached straps, and placed in the case of a power source, a control unit, a switch and two groups of light-emitting elements. The groups of light-emitting elements are controlled by means of a remote control panel. Such a vest has good visibility and can be mounted not only on the user's clothing, but also, for example, on a backpack or satchel. However, this vest is controlled by the user, therefore, he also has the above-noted disadvantage - the carrier of such a vest may not notice the light of the approaching car and not step aside, passing the car.

A technical problem solved by a utility model is the creation of a signal vest that can be worn either directly over clothes or over a backpack or briefcase, while ensuring visibility of the user in the dark not only when the headlights of the vest are illuminated with frontal lights that are equipped with reflective fabric. but also at a different angle of view, as well as a warning sound signal about the approaching car.

This problem is solved in a signal vest, comprising a case made of waterproof textile material with webbing attached to it, and a power supply, control unit, switch and two groups of light-emitting elements housed in the case.

According to the utility model, the vest is equipped with a light sensor and a loudspeaker, while the control unit is designed so that when the switch is turned on, the first group of light-emitting elements is activated, and if there is a signal from the light sensor, the loudspeaker and the second group of light-emitting elements are activated.

The technical result achieved when using such a signal vest is automatic activation in the case of light of the second group of light-emitting elements coming into contact with the light of the approaching vehicle in addition to the light-emitting elements of the first group that are already turned on while the loudspeaker is activated simultaneously. This makes it possible to increase the user's safety in the dark, because as a result of this work of the signal vest, the driver reflexively reacts to a change in the light signal, and the user draws attention to the unnoticed vehicle by a sound signal.

Preferably, the light emitting elements are light emitting diodes.

The control unit can be configured to turn on the flickering light of the light-emitting elements of the second group, which more attracts the attention of the driver.

Preferably the color of the light emitting elements in the first group is different from the color of the light emitting elements in the second group.

In addition, the signal vest can be additionally equipped with a reflective element.

The utility model is illustrated by drawings.

FIG. 1 schematically shows a signal vest according to a utility model;

in fig. 2 is a block diagram of the signal vest of FIG. one;

in fig. 3 shows one of the possible embodiments of a circuit diagram corresponding to the block diagram of FIG. 2

As shown in FIG. 1, the signal vest according to the useful one includes a body 1 made of waterproof textile material, for example, nylon, with webbing attached to it 2. The straps 2 can have connecting elements at their free ends and also contain means for adjusting the length. The connecting elements for the straps, as well as the means for adjusting their length, are well known, so they are not described in detail or shown in FIG. one.

In case 1, for example, in pockets made there, a power supply 3, a control unit 4, a switch 5, two groups 6 and 7 of light-emitting elements, an illumination sensor 8 and a loudspeaker 9 are placed.

In addition, on the outer side of the housing 1 is fixed reflective element 10, for example, in the form of a strip of retroreflective tape.

The power source 3 is preferably a rechargeable battery that can be connected to a connector installed in the housing 1 (conventionally not shown) for connecting a charger.

As shown in FIG. 2, control unit 4 through switch 5 is connected to power supply 3, groups 6 and 7 of light-emitting elements, light sensor 8 and loudspeaker 9. Control unit 4 is designed so that when switch 5 is turned on, the first group 6 of light-emitting elements is activated, and if there is a signal from the sensor 8 illumination activated loudspeaker 9 and the second group of 7 light-emitting elements. In addition, the control unit 4 may be configured to turn on the flickering light of the light-emitting elements of the second group 7.

Preferably the light-emitting elements in both groups 6 and 7 are made in the form of light-emitting diodes, for example, in the form of LED strips, and the color of the light emitting elements in the first group 6 is different from the color of the light-emitting elements in the second group 7. For example, the light-emitting elements in the first group 6 they are green and in the second group they are red.

Signal vest works as follows.

Before going out in the dark, the vest is put on outerwear or a backpack / satchel and manually turned on by the switch 5.

An outer light (group 6 light-emitting elements) lights up on the vest to provide greater visibility.

If the headlights hit the vest, the backlight (group 7 light-emitting elements) of a different shape and color (flickering can be added) lights up on the vest to provide greater visibility, and the loudspeaker 10 beeps on the vest.

The driver notices the child, and the child realizes that the car is moving in its direction.

After the headlights go off the vest, the vest returns to its original state.

The operation of the signal vest is illustrated by the circuit diagram shown in FIG. 3

To get started, turn on switch B, after which battery / battery power will be supplied.

In case of insufficient illumination (on the street in the evening), a current K1 does not pass through the coil; photodiode VD "closed". At the same time, through the normally closed contact K1.1 of the relay K1, the current passes and the LED L1 glows with a certain light, for example, green. At this time, the current does not pass through the normally open contact K1.2, and therefore the LED L2 does not light up and the loudspeaker G is turned off.

When the headlights hit the photodiode VD, it opens, current K1 starts to flow, and it works, as a result of which the position of the contacts K1.1 and K1.2 is inverted. At the same time, LED L1 goes out, LED L2 lights up, in particular, with a different color, and speaker G starts to make a sound.

When the light of the headlights disappears, the photodiode VD locks up, the current through the relay K1 does not pass, and the circuit returns to the one shown in FIG. 3 starting position.

This scheme is simplified, since it can be built on different components (transistors, microprocessors, etc.), instead of LEDs, you can use lamps or a number of LEDs. You can also further expand the scheme to control the glow (various types of flicker) and / or add a voice message "Caution, the car is coming."

Thus, when using a signal vest according to a utility model, a child who is wearing such a vest may not see the car, while the vest has light illumination of a certain color / shape, and when the headlights hit it, for example, from the back, the light sensor is triggered and the vest automatically changes the color and / or shape of the backlight and beeps. As a result, the driver reflexively reacts to a change in the light signal, and the child, by an audible signal, draws attention to the car he has not noticed.
