DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rod carried by a police officer, a security guard, or the like to organize and guide traffic to vehicles and pedestrians in traffic control and road construction.

[0002]

2. Description of the Related Art A guide rod which is generally used at present is often unclear for a guided person whether the instructor is instructing to proceed or to stop, and often loses judgment. Therefore, the arrangement and guidance of the traffic become incomplete, and there is a risk of causing traffic congestion and secondary traffic disasters.

To solve this problem, a portable red-green signal lamp (Japanese Patent Application Laid-Open No. 62-107397) and 2 have been proposed to provide a function of changing the color of the guide rod to red or blue.
A color signal lamp (Japanese Utility Model Laid-Open No. 4-85502) is known. The outline is, but on the right side of the fixed bulb, the upper 2/3 is red,
The remaining lower one-third is equipped with a green filter, and the other side is equipped with a filter with the above filter upside down. By raising and lowering both filters simultaneously, three combinations of signals are output to facilitate traffic control. It is assumed that.

In the prior art, colored cylinders of different colors are provided inside the protective cylinder, and the colored cylinders can be individually slid up and down so as to cover the light source. By sliding any one of the cylinders upward, it can be used by instantaneously switching to a stop or progress signal.

[0005] However, in the above-mentioned prior art, the two colored filters are slid up and down to change the color to red or blue, so that when one is above, the other filter below must be hidden. The colored portion of the guide light was halved in the longitudinal direction, and the entire guide light could not be effectively colored.

In addition, the mechanism for sliding up and down is complicated, and there is a drawback that repeated use causes many troubles.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention comprises a display section 10 and a reversing mechanism section 20 pattern section 30. The display unit 10 has a plurality of light source bulbs 11 arranged on the innermost side.
It is desirable to arrange two colors of 1a and blue light 11b and blink them alternately in accordance with a change in display. However, since a colored film described later emits light, it may be one type of an uncolored light bulb. .

Surrounding the light source bulb 11, the display tube 1 is vertically elongated.
2 is disposed on the outside of the display tube 12, and a translucent colored film 13 in which two colors of a red portion and a blue portion are connected to each other is covered, and a pair of rolls capable of winding the colored film on the inside. The take-up rolls 14 and 15 are arranged in parallel with each other,
A winding groove 12a for winding the coloring film 13 is formed in the vertical direction. For example, the display cylinder 12 has a diameter of 30 mm.
Is formed of a transparent material having a length of about 330 mm, and a dimension width πR = 9 capable of covering the entire outside of the display tube 12 there.
The red film 13a is formed of a transparent and flexible material of 4.2 mm, and similarly, the blue film 1 is formed of 94.2 mm in width.
3b to make a continuous film. An outer tube 16 for protecting the inside is formed of a transparent material on the outermost side.

One end of the colored film 13 is guided into the display tube 12 through the winding groove 12a, and is fixed to one of the winding rolls 14 and 15, so that the colored film 13 can be wound on the winding roll 14. . On the other hand, the other end is also fixed to the other winding roll 15 via the winding groove 12a, so that it can be wound in the opposite direction to the winding roll 14. That is,
When the blue film 13b is wound around one of the winding rolls 14, the outside of the display tube 12 is entirely covered with the red film 13a.
Is wound, the entire display tube 12 is covered with the blue film 13b.

The winding rolls 14, 15 are provided with a reversing mechanism 20.
Connected to. In the reversing mechanism, a handle 21 is disposed at a base end, a handle gear 22 is axially mounted on the handle 21, and a first guide gear 23 in which small teeth 23a and large teeth 23b are combined is meshed with the handle 21. And the second guide gear 24 in which the similar small teeth 24a and large teeth 24b are combined. The second guide gear is provided with a shaft gear 25 axially mounted on one of the winding rolls 14 and 15, and further provided with roll gears 26 and 27 meshed with gears having the same number of teeth. To wear. Handle 21
Is rotated right and left, the rotational force is transmitted to the shaft gear 25 via the first and second guide gears 23 and 24, and is transmitted to the winding roll 14 via the roll gears 26 and 27. , 1
5 are rotated in opposite directions.

Although the handle 21 is generally a manual mechanism as described above, it may be electrically driven. In that case, as shown in FIG. 5, a motor capable of rotating forward and reverse is directly connected to one of the winding rolls 14 and 15 and connected to a power source. And a circuit for turning the motor forward or backward by operating the three-way switch 28 is formed. Part b of the circuit is provided with b-contact switches 29a and 29b. The switches 29a and 29b are turned on / off by the turning operation of the terminal handle 21 at the end of the circuit. The structure is such that the switch is automatically turned off.

A handle 31 serving as a gripping rod of the guide rod incorporates a battery 31 and a switch 32 is provided.

The operation of this embodiment will be described. First, when the driver or pedestrian of the vehicle is instructed to stop by the guide rod 1, the steering wheel 21 is turned in one of the right and left directions. . Then, the rotational movement of the handle 21 turns the handle gear 22 of the reversing mechanism 20 (forward direction), and the small teeth 23a of the first guide gear 23 and the large coaxial teeth 23 meshed therewith.
Rotate b in the opposite direction. Accordingly, the small teeth 24a and the coaxial large teeth 24b of the second guide gear 24 are rotated in the forward direction,
The shaft gear 25 meshed with this is rotated in the opposite direction. Then, the take-up roll 14 coaxial with the shaft gear 25 rotates in the reverse direction, the roll gear 26 rotates in the forward direction, and the other take-up roll 15 rotates in the forward direction.

The movement of the reversing mechanism 20 causes the winding roller to move.
The rolls 14 and 15 rotate in opposite directions facing each other, and as a result, the colored film 13 adhered to one end of the roll 14.
(For example, the blue film 13b) is wound in, and the rolled red film 13a is fed out from the other roll 15. The unwound red film 13a passes through the winding groove 12a, travels along the surface of the display cylinder 12 and is pulled by the blue film 13b wound on the other winding roll 14 while covering the surface. On the other hand, the blue film 13b is wound around the winding roll 14 through the winding groove 12a by the winding action.

As a result, the blue film 13b is taken up by the winding roll.
Around the display tube 12 and is hidden inside the display tube 12, while the red film 13a is fed out and covers the entire display tube 12 (see FIG. 3A). Therefore, the transparent outer cylinder 16
When a driver or the like observes this from outside, it can be identified that the entire guide rod is displayed in red.

Further, at night or the like, a switch for the light source bulb 11 is provided.
When the button 32 is pressed, the red light bulb is turned on, and when it is lit in a blinking display or the like, the red color of the guide rod can be more clearly recognized.

Next, when the user instructs to proceed, the operation is performed in a completely reverse manner to rotate the handle 21 in the opposite direction. Then, contrary to the above, the handle gear 22, the first guide gear 23, and the second guide gear 24 of the reversing mechanism 20 rotate in the opposite direction, and the winding rollers 14, 15 move in the opposite direction. Rotate.

Then, the red film 13a fixed to one end of the take-up roll 15 is rolled up, and the rolled-up blue film 13b is unwound from the other roll 14, and the blue film 13b is fed into the winding groove 12a. After that, it is pulled by the red film 13a wound on the other winding roll 15 while covering the surface of the display cylinder 12. On the other hand, the blue film 13b is wound around the winding roll 15 through the winding groove 12a by the winding action. As a result, the red film 1
3a is hidden in the display tube 12, and the blue film 13b is extended to cover the entire display tube 12 (see FIG. 3B).

This reversing operation is completed in an instant, and the operation mechanism by the gears and the roll is reliable and has few failures.

When the handle is an electric mechanism,
By operating the three-way switch 28, forward rotation and reverse rotation are alternately given to the motor, so that the forward and reverse rotation of the motor can be performed only by operating the three-way switch 28. 14,1
5, the winding rolls 14, 15 can be rotated forward and reverse. At that time, the b-contact switches 29a, 29b are turned on / off by the handle 21 of the reversing mechanism 20, so that the circuit is cut off after a predetermined rotation, and the winding rolls 14,1 are automatically turned on.
5 can be completed.
