[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flag hoisting device used for displaying a flag on a pole.

[0002]

2. Description of the Related Art Usually, a flag is displayed at the tip of a tall pole. A pulley is provided on the top of the pole, and a rope is attached to the pulley, and the rope is wound by a bobbin provided on the base end side of the pole. By rotating the bobbin about the axis with the flag attached to the rope, the flag can be raised and lowered along the pole.

[0003] Such a flag hoisting device has a rope exterior system in which a two-way reciprocating rope mounted on a pulley is exposed outside a pole and a bobbin is also provided outside the pole.
One of the two ropes is housed inside the cylindrical pole, and the bobbin can also be classified into two types: a rope interior system provided inside the pole.
The rope exterior method has a drawback in that the two exposed ropes hang down from the pole, and these externally exposed ropes impair the appearance of the displayed flag. Therefore, recently, there has been a tendency to use a winding device of a rope interior type.

FIG. 9 is a cross-sectional view illustrating a conventional flag hoisting apparatus of a rope interior type. As shown in this figure, a hoisting device 10 includes an apparatus main body 20 that is mounted in a mounting hole P1 formed on the base end side of a cylindrical pole P,
0, and a rotating mechanism 30 provided inside the rotating mechanism 3
A lock mechanism 40 for locking the rotation about the axis 0, a bobbin 50 connected to the rotation mechanism 30 in the pole P so as to be rotatable around the axis, and a detachable attachment / detachment part of the rotation mechanism 30 exposed from the pole P. And a handle 60 provided freely.

[0005] The apparatus main body 20 has a cylindrical body 210.
A flange portion 220 provided on the base end side (right side in FIG. 9) of the body portion 210; and a support rod 230 erected above and below the flange portion 220 toward the distal end side (left side in FIG. 9). And a support plate 240 screwed to the support rod 230. And the trunk 21
0 is fitted into the pole P from the mounting window P1, and the apparatus main body 20 is fixed to the pole P with the flange portion 220 screwed to the surface of the pole P.

The rotating mechanism 30 has a drum 310 fitted into the body 210 of the apparatus main body 20 so as to be rotatable about an axis and slidable in a horizontal direction, and is corotatable with a tip side of the drum 310. And a gear 320 provided in the gearbox. A bobbin 50 for winding the rope R is provided concentrically on the distal end side of the gear 320 and
A detachable handle 60 is provided on the base end face of the handle 10.

A connecting portion 310a having a small diameter extends on the tip side of the drum 310, and the connecting portion 310a is fitted into a connecting hole formed in an axial portion of the gear 320 via a coil spring. The two are joined. Further, between the drum 310 and the connection portion 310a, an inclined portion 310b tapering toward the distal end side is formed.

The gear 320 is connected to the body 2 of the apparatus body 20.
10 is sandwiched between the front end surface of the base 10 and the support plate 240,
The diameter is set to be larger than the diameter of the body 210. Therefore, the teeth 330 of the gear 320 project radially outward from the outer periphery of the body 210.

The lock mechanism 40 includes a plate-shaped stopper 410 rotatably supported on a bracket B at a root portion of the flange portion 220 so as to be rotatable around a support shaft, and a body portion 210.
The through-hole 21 drilled corresponding to the stopper 410
0a. The stopper 410 is urged counterclockwise around the support axis by the urging force of the coiled small spring 430, and its lower edge portion comes into contact with the head of the pin 420.

Accordingly, the pin 420 is pushed into the through hole 210a via the stopper 410 by the urging force of the coiled small spring 430. Pin 4 in this state
The front end of the drum 20 is dimensioned so as to contact the outer peripheral surface of the connecting portion 310a at the lowermost part of the inclined portion 310b of the drum 310.

Then, the tip of the pin 420 is
Since the tip of the stopper 410 is dimensioned so as to mesh with the teeth 330 of the gear 320 in a state where the stopper 410 is in contact with the outer peripheral surface of the rotating mechanism 30, the engagement of the stopper 410 with the gear 320 usually causes the rotation mechanism 30 to rotate. The rotation is blocked. Therefore, even if tension is applied to the rope R by the weight of the flag (not shown), the bobbin 50 that rotates together with the rotating mechanism 30 does not rotate, and the height position of the flag is set.

When the flag is to be hoisted, first, the handle 6
0 may be applied to the drum 310. Then, the drum 310 moves to the left against the urging force of the urging means. This movement causes the inclined portion 310b to move to the left as shown by the two-dot chain line, and is guided by this movement to cause the pin 4
20 rises in the through hole 210a, and its head pushes the stopper 410 upward, so that the engagement between the stopper 410 and the gear 320 is released, and the rotating mechanism 30 can rotate around the axis.

Therefore, the bobbin 50 can be rotated by rotating the handle 60 in a state in which the lock by the stopper 410 is released, that is, in a state in which the rotating mechanism 30 is pressed by the handle 60. The flag can be wound around the bobbin 50. When the pressing operation of the handle 60 is released, the coiled small spring 43 is released.
The lowering of the pin 420 based on the urging force of 0 causes the stopper 410 to rotate counterclockwise around the support axis, the stopper 410 meshes with the gear 320 again, and the rotating mechanism 30 is locked.

[0014]

However, the conventional hoisting device 10 as described above has a large number of parts as a whole and has a complicated structure. In addition, there is a problem that the production cost is generally increased, for example, it takes much time.

The lock mechanism 40 includes a small small coiled spring 430, a plate-shaped stopper 410 urged by the small coiled spring 430,
Pin 4 for raising and lowering 10 by horizontal movement of rotation mechanism 30
20 and a structure with a large number of movable parts, so that it is extremely easy to break down. Normally, the flag hoisting device 10 is provided outdoors in a field-exposed state, so that internal corrosion is likely to occur due to penetration of raindrops (in particular, the coiled small spring 43).
0 often erodes and fails the function of the spring), and the synergistic effect of this erosion and structural complexity further promotes failure.

Finally, the conventional hoisting device 1 as shown in FIG.
In the case of No. 0, the lock mechanism 40 frequently fails, and the service life is short, so that the user must frequently perform inspection and repair, and there is an inconvenience that the maintenance cost is high.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a small number of parts, therefore has a low manufacturing cost, and is capable of reducing the frequency of failures. It is intended to provide an upper device.

Then, the rope R in the pole P is pulled up by the weight of the weight W, and the bobbin 6 shown in FIG. 2 naturally rotates clockwise around the central axis 5 by the action of the freewheel F,
Accordingly, the operation handle 7 also rotates in the same direction, the rope R wound on the bobbin 6 is rewound, and as a result, the flag H descends.

In the natural rotation, the flange 6 of the bobbin 6
Since the side surface of the bobbin 6 is pressed by the brake piece 34c protruding from the through hole 35 of the support plate 3 and is in an appropriate braking state, the rotation speed of the bobbin 6 around the axis is restricted, and the rope R is rewound. It is suitable for

In FIG. 2, even if the operating handle 7 is rotated clockwise around the central axis 5 at a higher rotation speed than the natural rotation, the central axis 5 is moved to the bobbin 6 by the action of the freewheel F. To idle,
The bobbin 6 does not rotate at a speed higher than the rotation speed of the natural rotation, and the inconvenience of the ropes R entangled due to the slackness of the ropes R caused by the quick rotation of the operation handle 7 is effectively avoided.
