[0002]

2. Description of the Related Art Guide rods that are generally used at present have often been unclear to the guided person whether the instructor orders the progress or the stop. Therefore, there is a risk that traffic control and guidance will be incomplete, leading to traffic congestion and secondary traffic accidents.

In order to solve this problem, a portable red-green signal lamp (Japanese Patent Laid-Open No. 62-107397) and 2 are proposed as a means of providing the guide rod with a function of changing the color to red or blue.
A color indicator lamp (Jitsukaihei 4-85502) is known. The outline is, but on the right side of the fixed light bulb, the upper 2/3 is red,
A green filter is placed on the remaining lower 1/3 and a filter with the filter above is placed on the opposite side. By raising and lowering both filters at the same time, three different combinations of signals are output, making traffic control easier. It is what

In the above, since the colored cylinders of different colors are provided inside the protective cylinder and the colored cylinders can be slid up and down individually so as to cover the light source, the colored cylinders can be colored during traffic control or guidance. By sliding any one of the cylinders upward, it is possible to instantaneously switch to each of the cues for stopping and advancing.

However, in the above prior art, the two colored filters are slid up and down to change the color to red or blue. Therefore, when one is on the upper side, the other filter on the lower side 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.

Further, the mechanism for sliding up and down is complicated, and there are drawbacks such as frequent failures during repeated use.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention comprises a display portion 10, a reversing mechanism portion 20 and a handle portion 30. Several light source bulbs 11 are arranged on the innermost side of the display unit 10.
It is desirable that two colors, 1a and blue light 11b, are arranged and blink alternately according to the change of the display, but since the colored film described later illuminates, it may be one type of uncolored light bulb. .

The display cylinder 1 is vertically long and surrounds the light source bulb 11.
2 is arranged, the outer side of the display cylinder 12 is covered with a light-transmitting colored film 13 in which two colors of a red part and a blue part are connected, and a pair of windings capable of winding the colored film inside. The display rolls 12 and 15 are arranged in parallel with each other, and
A winding groove 12a for winding the colored film 13 is formed in the vertical direction. For example, the display cylinder 12 has a diameter of 30 mm.
And a dimension width πR = 9, which is formed of a transparent material having a length of about 330 mm and can cover the entire outside of the display cylinder 12.
The red film 13a having a thickness of 4.2 mm is formed of a transparent and flexible material, and the blue film 1 having a width of 94.2 mm is also formed.
3b is connected to form a continuous film. An outer cylinder 16 for protecting the inside is formed of a transparent material on the outermost side.

Then, one end of the colored film 13 is introduced into the display cylinder 12 through the winding groove 12a, fixed to one of the winding rolls 14 and 15, and wound around the winding roll 14. It can be taken. 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 cylinder 12 is entirely covered with the red film 13a, and in the opposite case, the entire display cylinder 12 is covered with the blue film 13b. Be made aware of it.

The winding rolls 14 and 15 have a reversing mechanism 20.
Connected to. The reversing mechanism has a handle 21 at its base end, a handle gear 22 is pivotally attached to the handle 21, and a first guide gear 23 in which a small tooth 23a and a large tooth 23b are combined is meshed with this. Further, the second guide gear 24 in which the same small teeth 24a and large teeth 24b are combined is meshed. A shaft gear 25, which is rotatably mounted on one of the winding rolls 14 and 15, is arranged on the second induction gear, and further, roll gears 26 and 27 are meshed with gears having the same number of teeth. To wear. Handle 21
When it is rotated to the left and right, its rotational force is transmitted to the shaft gear 25 via the first and second guide gears 23 and 24, and it is transmitted via the roll gears 26 and 27 to the take-up roll 14. , 1
5 is a mechanism for rotating in the opposite directions.

The handle 21 is generally a manual mechanism as described above, but may be an electric type. In that case, as shown in FIG. 5, a forward or reverse rotatable motor is directly connected to either one of the winding rolls 14 and 15, and this is connected to the power source, while the three-way switch 28 is provided therebetween. And a circuit for applying a normal rotation or a reverse rotation to the motor by operating the three-way switch 28. Then, b-contact switches 29a and 29b are provided in a part of the circuit, and the switches 29a and 29b are turned on / off by the rotation operation of the handle 21 at the end, and when the rotation of the winding roll is completed. The structure is such that the switch can be turned off automatically.

A battery 31 is built into the handle portion 30 which serves as a handle for the guide rod, and a switch 32 is provided.

The operation of this embodiment will be described. First, when the guide rod 1 is used to instruct a driver of a vehicle or a pedestrian to stop, the handle 21 is turned to the right or left in a predetermined direction. . Then, the rotational movement of the handle 21 rotates the handle gear 22 of the reversing mechanism 20 (forward direction), and the small tooth 23a of the first guide gear 23 and the large tooth 23 of the same shaft which mesh with this.
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 positive 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 opposite direction, and the roll gear 26 rotates in the positive direction to rotate the other take-up roll 15 in the positive direction.

The movement of the reversing mechanism 20 causes a winding roll.
The rolls 14 and 15 face each other and rotate in opposite directions, so that the colored film 13 fixed to one end of the roll 14
(For example, the blue film 13b) is wound, and the wound red film 13a is paid out from the other roll 15. Then, the red film 13a fed out passes through the winding groove 12a, travels along the surface of the cylindrical body of the display cylinder 12, covers the surface, and is pulled by the blue film 13b wound on the other winding roll 14. 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 rolled up.
The film 14 is wound around the display tube 12 and hidden inside the display tube 12, while the red film 13a is unwound and covers the entire display tube 12 (see FIG. 3A). Therefore, the transparent outer cylinder 16
When the driver or the like observes it from the outside, it can be identified that the entire guide rod is displayed in red.

Further, when the switch 31 of the light source bulb 11 is pushed at night or the like, the red bulb is turned on, and when it emits light in a blinking display, the red color of the guide rod can be recognized more clearly.

Next, in the case of instructing to proceed in the opposite direction, the operation reverse to the above is performed and the handle 21 is rotated 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 to the above, and the take-up rolls 14 and 15 move in the opposite direction to the above. Rotate.

Then, the red film 13a fixed to one end of the winding roll 15 is wound, the wound blue film 13b is fed from the other roll 14, and the blue film 13b is wound into the winding groove 12a. After that, while being covered with the surface of the display cylinder 12, it is pulled by the red film 13a which is wound around the other winding roll 15. On the other hand, the blue film 13b is wound around the winding roll 15 through the winding groove 12a by its winding action. As a result, red film 1
3a is hidden in the display cylinder 12, and the blue film 13b is paid out to cover the entire display cylinder 12 (see FIG. 3B).

This reversing operation is completed in an instant, and the gear and roll actuating mechanism 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 applied to the motor. Therefore, only by operating the three-way switch 28, forward rotation and reverse rotation of the motor can be taken up. 14, 1
5, the take-up rolls 14 and 15 can be rotated normally and reversely. 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 after a predetermined rotation and the winding rolls 14, 1 are automatically turned.
The rotation of 5 can be ended.

[0026]

According to the present invention, since the entire display cylinder occupying the display portion of the guide rod can be completely covered with the red or blue colored film, the entire display portion can be colored and displayed, and its effectiveness is the most. Highly, the guided person can clearly discriminate the instructions of police officers and security guards even from a distance, and has an excellent effect of being able to pass with confidence. Moreover, if the switching is done manually, it consumes less power and does not require battery replacement even if it is used for a long time at night. Also, if it is electrically operated, it consumes a lot of power but can be easily switched only by switching. It can be performed. Further, since the mechanism is simple, there are few failures, and reliable operation can be continued.
