Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic winding yellow flag used by a security officer to guide a general traffic vehicle or a construction vehicle on a construction section or an accident section of a highway or a general road.

  As the automatic winding yellow flag as described above, a flag stick with a handle and an upper end of a bunting attached thereto is widely used. The Ministry of Land, Infrastructure, Transport and Tourism specifies that buntings have a size of 70 × 70 cm or more and have good visibility, so yellow or orange buntings having a size of 90 × 90 cm are generally used. The automatic winding yellow flag in this specification includes a fluorescent flag in addition to yellow or orange.

  Such a self-winding yellow flag is used to guide the vehicle to approach one lane, to instruct the vehicle to slow down, or to instruct the vehicle to stop. The method of swinging and lowering is defined for each case, but especially when swinging largely overhead, the bunting is easily entangled with the flag stick. In view of this, Patent Document 1 proposes an automatic winding yellow flag in which a flag stick is rotatable with respect to a handle so that bunting is less likely to be entangled with the flag stick.

  If the structure of Patent Document 1 is adopted, the problem of entanglement can be solved to some extent. However, even if the security guard used is holding the steering wheel, the flag stick rotates freely, and if the flag stick is lowered horizontally, the bunting will hang down to the lowest position. For this reason, as shown in FIG. 8, the lower end of the bunting sticks to the ground when used by a short guard, and when the foot is stepped on from this state, the bunting may become entangled with the foot and trip.

  In addition, when using a general self-winding yellow flag with a flag stick fixed to the handle, when taking the standby position with the flag stick lowered horizontally, the security guard rotates the handle to match the height. The bunting can be rolled up so that the lower end of the bunting does not touch the ground. However, when this operation is performed, the line of sight remains downward, and attention to the front is neglected. This tendency is remarkable especially for inexperienced security guards, and even in security training sessions, leaders often receive caution.

JP-A-2003-131602

  Accordingly, an object of the present invention is to solve the above-mentioned conventional problems, and to wind up a bunting so that the lower end of the bunting does not stick to the ground while facing forward even when a short guard is used. Is to provide a self-winding yellow flag.

  The present invention made in order to solve the above-mentioned problem is an automatic winding yellow flag comprising a bunting, a flag stick having its upper end fixed, and a handle for holding a base of the flag stick. A motor that can rotate the flag stick in both forward and reverse directions and a battery that serves as its power supply are built in, and a motor switch is arranged on the surface of the handle, and the flag stick is rotated by operating the switch to wind up the bunting. It is characterized in that it can be unwound.

  It is preferable that the handle is provided with a flag bar holder to which the base of the flag bar can be attached and detached. It is preferable that the motor is a geared motor.

  The automatic winding yellow flag of the present invention is a flag that is rotated by operating a switch provided on the handle to enable the winding up and down of the bunting. Without turning down, the bunting can be wound so that the lower end of the bunting does not touch the ground. Therefore, it is excellent in safety. In addition, when the user shakes the camera overhead, it can be easily returned to the original standard size.

It is an overall view of an automatic winding yellow flag of an embodiment. It is the elements on larger scale of the automatic winding yellow flag of an embodiment. It is a top view of an automatic winding type yellow flag of an embodiment. It is a front view of a handle | steering-wheel unit. It is a vertical sectional view showing the internal structure of a handle. It is a horizontal sectional view showing the internal structure of a handle. It is an explanatory view of a use state. It is a figure showing the state where the lower end of bunting was attached to the ground.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 is an overall view of an automatic winding yellow flag according to an embodiment of the present invention, FIG. 2 is a partially enlarged view thereof, and FIG. 3 is a plan view. The automatic winding yellow flag of the present invention also includes a bunting 10, a flag stick 11, and a handle 12 for holding the base of the flag stick 11, as in the related art. The flag cloth 10 has a size of 90 × 90 cm, and its color is yellow, orange, or a yellow fluorescent color. The upper end of the bunting 10 is attached to the flag stick 11 so as not to rotate.

  4 is a front view of the handle 12, FIG. 5 is a vertical sectional view showing the internal structure thereof, and FIG. 6 is a horizontal sectional view. As shown in FIG. 4, a flag stick holder 14 protrudes from an end of the handle main body 13, and the base of the flag stick 11 can be inserted into and fixed to the flag stick holder 14. The flag bar holder 14 is, for example, a pipe having a diameter of 15 mm. Many flag sticks 11 are formed of pipes having a diameter of 13 mm, and the bases thereof may be inserted as shown in FIGS. It is preferable to form a non-slip 15 on the outer periphery of the handle body 13.

  As shown in FIG. 5, a motor 16 rotatable in both forward and reverse directions is provided inside the handle 12. The motor 16 is a DC motor, and is fixed to the center of the handle body 13 by a motor fixing bracket 17. .

  The tip of the rotating shaft 17 of the motor 16 is fixed to the column 18, and the tip of the column 18 is fixed inside the flag stick holder 14. The flag rod holder 14 is rotatably held with respect to the handle main body 13 by two pipe holders 19 at the front and rear. Therefore, if the motor 16 is rotated, the flag bar holder 14 can be rotated, and the flag bar 11 inserted into the flag bar holder 14 can be rotated.

  A battery 20 serving as a power source for the motor 16 is built in a rear portion of the handle body 13. In the present embodiment, a 9V battery is used, but the voltage and the type of battery can be appropriately selected. A battery cap 21 is attached to the rear end of the handle body 13, and when the battery 20 is replaced or charged, the battery 20 can be easily taken out by removing the battery cap 21.

  On the surface of the handle body 13, a motor switch 22 is arranged. The motor switch 22 switches the polarity of the current supplied from the battery 20 to the motor 16 to rotate the motor 16 forward or reverse. Further, the motor 16 can be rotated only during the time when the switch is turned on. The type of the motor switch 22 is arbitrary, and two switches for normal rotation and reverse rotation may be arranged in addition to the changeover switch shown in the figure.

  The self-winding yellow flag of the present invention configured as described above is used for a security officer to guide a vehicle on an expressway or a general road as in the case of the conventional one. By rotating the flag bar 11, the bunting 10 can be wound up and down. For this reason, when entering the standby position shown in FIG. 7, the security staff operates the motor switch 22 of the handle body 13 to wind up the bunting 10 according to his / her height, and the lower end of the bunting 10 is attached to the ground. Can be eliminated. Therefore, there is no risk of tripping when used by security guards with a short height.

  In addition, since this operation can be performed without paying attention to the front without turning the line of sight downward, safety is excellent. In addition, when a large swing operation is performed above the head, by operating the motor switch 22, the rolled-up flag cloth 10 can be quickly returned to its original state.

  In addition, as in this embodiment, if the flag bar 11 is made detachable by providing a flag bar holder on the handle, the flag bar 11 can be easily replaced when it is dirty or torn.

  Since both the flag cloth 10 and the flag stick 11 are lightweight, the motor 16 and the battery 20 may be small. Therefore, the weight increase of the handle 12 is very small as compared with the conventional product, and the center of gravity is located at the position of the handle 12, so that there is an advantage that the flag can be easily operated.
