BACKGROUND OF THE INVENTION
[0001] The present invention relates to a working garment with positive flickering devices
in which a front, a rear and two lateral sides of the working garment are arranged
with multiple positive flickering devices disposed on the reflecting strips for providing
identification effect in all directions. By means of the widened projecting angle
and enlarged projecting area of the light emitting diode and light reflecting members,
the projecting range is enlarged and the illumination is enhanced, whereby the warning
effect can reach a long distance to ensure the safety of the worker.
[0002] Fig. 1 shows a conventional safety working garment 1' disposed with reflecting strips
11' for showing the position of the worker at night. However, such reflecting strip
11' can be only identified in short distance. Therefore, when driving at night, a
driver can hardly identify the worker in long distance and avoid the worker in time.
This often leads to serious accident. Fig. 2 shows another working garments 2' which
is disposed with light emitting diodes 21' and reflecting strips 11' to emit flickering
light by wider angle so as to warn the driver. However, the light emitting diodes
have insufficient illumination and small projecting area, so that the driver can only
see and brake to avoid the worker in short distance. Therefore, the safety of the
worker cannot be ensured.
SUMMARY OF THE INVENTION
[0003] It is therefore a primary object of the present invention to provide a working garment
with positive flickering devices in which the light emitting diode directly projects
light onto the light reflecting members to reflect the light, whereby the projecting
angle is widened and the projecting area is enlarged projecting area and the illumination
is enhanced to achieve a warning effect in a long distance.
[0004] It is a further object of the present invention to provide the above working garment
in which a front, a rear and two lateral sides of the working garment are arranged
with multiple positive flickering devices disposed on the reflecting strips for providing
identification effect in all directions.
[0005] It is still a further object of the present invention to provide the above working
garment in which the positive flickering device has small volume and can be easily
disposed on the garment.
[0006] The present invention can be best understood through the following description and
accompanying drawings, wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] Please refer to Fig. 3. the working garment 1 of the present invention is disposed
with multiple positive flickering devices 2 arranged along the reflecting strips on
front, rear and two lateral sides of the working garment 1. Each positive flickering
device 2 has flat pattern minimized structure and can be easily disposed on the working
garment to indicate the worker in all directions.
Referring to Figs.4 and 5, multiple positive flickering devices 2 are arranged along
the reflecting strips of the left and right shoulder straps and the lower waist strap
of the working garment 1. Also, on back side, multiple positive flickering devices
2 are arranged along the reflecting strips of the shoulder straps and the waist strap.
Fig. 4 shows that the working garment can be put on or taken off via a fastening belt.
[0009] Fig. 5 shows the circuit diagram of the working garment 1. The circuit is composed
of a button switch 3a, an oscillator 4, a current-limiting device 41, a driver 42,
multiple positive flickering devices 2 and a power supply 5. By means of depressing
the button switch 3, the circuit is closed and the power supply 5a can supply power
therefore. At this time, the oscillator 4 sends out periodic flickering signals. The
current-limiting device 41 serves to prevent great current from passing the circuit
and protect the driver 42. The driver 42 serves to amplify and drive current to make
the multiple positive flickering devices 2 flicker.
[0010] Referring to Fig. 6, according to another embodiment of the present invention, the
circuit is composed of a button switch 3, a pulse generator 4, a current-limiting
device 41, a driver 42, multiple positive flickering devices 2 and a power supply
5. By means of depressing the button switch 3b, the circuit is closed and the power
supply 5 can supply power therefor. At this time, the pulse generator 4 sends out
periodic flickering signals. The current-limiting device 41 serves to prevent great
current from passing the circuit and protect the driver 42. The driver 42 serves to
amplify and drive current to make the multiple positive flickering devices 2 flicker.
[0011] Referring to fig. 7, the positive flickering device 2 is composed of a casing 27,
a connecting wire cover 24, light-reflecting combined body 21, light emitting diode
22, connecting support 25 and upper and lower covers 23, 26.
[0012] The casing 27 of the positive flickering device 2 serves to enclose the light-reflecting
combined body 21 which designed as a trapezoid sink so as to widen the projecting
angle and enlarge the projecting area. A light-reflecting member 211 is attached to
each surface of the combined body 21 for reflecting the light emitted from the light
emitting diode22. The insertion pins 221 and insertion sockets 222 thereof are passed
through the insertion hole 223 to be integrally inserted with the insertion pin 251
of the connection support 25 of the connecting wire cover 24. The thrusting arm 253
penetrates through the skin of the conducting wire to electrically connect the conducting
wire with the light emitting diode 22 via the connecting support 25. the upper and
lower covers 23, 26 cooperatively secure the above elements in the casing 27.
[0013] The positive flickering device 2 projects light as shown in figs. 8 and 9. The reflecting
member 211 reflects the light from the light emitting diode22. By means of the widened
projecting angle and enlarged projecting area of the combined body 21, the projecting
range is enlarged and the illumination is enhanced, whereby the warning effect can
reach a long distance.
[0014] The working garment with the flickering device of the present invention is advantageous
over the conventional safety working garment as follows:
1. A long distance identification can be achieved.
2. By mans of the light emitting diode and the light reflecting member, the positive
flickering device can project light with enhanced illumination.
3. The front, rear and two lateral sides of the working garment are disposed with
multiple positive flickering devices parallelly connected on the reflecting strips
for providing warning effect in all directions.

illustrating one embodiment of the present invention, not intended to limit the scope
thereof. Any variaton and derivation from the above description and drawings should
