Abstract

The present invention provides a light emitting device in which a plurality of light emitting elements are inserted along a center line of the width of the reflective vinyl tape so as to significantly increase the discriminating power while preventing the deterioration of the identification function at night without any inconvenience to wear, and the light emitting elements at regular intervals. It provides a safety vest, characterized in that consisting of the oscillator to be flashing.

The safety vest of the present invention inserts a light emitting device which blinks at regular intervals along the centerline of the width of the reflective vinyl tape to increase the discriminated power and solves the problem of the safety vest, which was only dependent on the reflecting power due to external lighting. Unavoidable accidents can be prevented in advance, further securing safety on the road.

Description

Safety vest

The present invention relates to a safety vest, and more particularly, to a safety vest to attach a light emitting element along the centerline of the width of the reflective vinyl tape attached to the front and rear of the safety vest and to blink at regular intervals.

The nighttime is narrower than the daytime, so it takes more time than the daytime to identify the front or side objects when driving the vehicle.

In particular, the workers who work at night in the vicinity of the road are at greater risk. To prevent this, the safety of the lamp is kept by shaking the lamp to inform them of their location. This falls, and in some cases can not work.

In order to alleviate this inconvenience, a safety vest with a reflective vinyl tape 1 having a property of reflecting light is worn as shown in FIGS. 1 (a) and 1 (b).

However, due to the work near the road, the reflective vinyl tape 1 may be easily contaminated by a relatively large amount of dust and contaminants, so that the original function may not be sufficiently exhibited. ) Is often dangerous because it does not reflect light or reflects light that is indistinguishable.

The present invention has been made to solve the above problems, and to provide a safety vest that can significantly increase the discrimination power by preventing the degradation of the identification function at night without inconvenience to wear.

1 (a) and 1 (b) are front and rear views of a conventional safety vest with a V-shaped reflective vinyl tape attached to the front and back.

2 (a) and 2 (b) is a view showing a front view and a rear view of the safety vest of the present invention with a light emitting element attached to the center of the reflective vinyl tape of the safety vest according to the present invention.

3 (a) is a view showing an oscillator for blinking the light emitting device shown in 2 (a) and 2 (b),

FIG. 3 (b) is a circuit diagram showing an embodiment of the circuit board of the oscillator shown in FIG. 3 (a).

Explanation of symbols on the main parts of the drawings

1: reflective vinyl tape

2: LED light emitting element

3: switch

4: circuit board

5: battery

The present invention for solving the above problems is characterized in that it comprises a plurality of light emitting elements arranged at regular intervals along the center line of the width of the reflective vinyl tape, and the oscillating portion for blinking the light emitting element at a predetermined period Provide safety vests.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the safety vest according to the present invention will be described in detail.

2 (a) and 2 (b) is a front view and a rear view showing an embodiment of the present invention, in this embodiment the V-shaped reflective vinyl tape (1) on the front and rear of the safety vest 4 LED light-emitting elements 2 are attached to the front and the rear, respectively, along the center line of the width of the reflective vinyl tape 1.

FIG. 3 (a) is a diagram showing an oscillation part including a circuit board and a battery that flashes a light emitting element at a predetermined cycle, and takes into consideration the characteristics of a night worker near a road that must move or continue working. The size of each 1cm horizontal and vertical, each of the small battery (5) is adopted, and the light emitting device is adopted to the LED light emitting diode to operate at a low power to eliminate the inconvenience to wear by being embedded in the lower left of the safety vest.

3 (b) shows a specific circuit diagram of the circuit board 4 of FIG. 3 (a).

The embodiments described above are not intended to limit the present invention but to illustrate them.

For example, in the illustrated embodiment, the number of LED light emitting elements is four, but may be added or subtracted in some cases. In addition, the position of the LED light emitting device, the shape of the reflective vinyl tape, or the blinking period of the LED light emitting device can be appropriately changed in accordance with the change of R1, R2, C2 values, which are characteristic values of the device.

Therefore, the present invention is not limited to the illustrated embodiments, but will include all changes or modifications that will be apparent to those skilled in the art and the scope of the present invention will be defined within the appended claims.

As described in detail above, the safety vest of the present invention inserts a light emitting device that blinks at a predetermined interval in the center of the reflective vinyl tape to increase the discrimination power, thereby solving the problem of the safety vest that was only dependent on the reflecting power due to external lighting. It is possible to further secure safety on the road by preventing accidents caused by vehicles or the like in advance.

Claims (1)

A safety vest with at least one strip of reflective vinyl tape attached to the front and back, A plurality of light emitting elements arranged at regular intervals along a centerline of the width of the reflective vinyl tape; Safety vest, characterized in that it comprises an oscillator for flashing the light emitting element at a predetermined cycle.
