Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a winding device for a flag lifting wire, etc. on a flagpole.

Conventional technology Conventionally, in a type of flagpole in which a flag lifting wire or string (hereinafter referred to as wire, etc.) is housed inside the flagpole, when the wire, etc. is sent out from the spool to lower the flag, the flag is exposed to strong winds, etc. If the flag gets tangled in the flagpole, the flag may not come down and the wires may become loose and continue to be sent out. In such a case, the loose wires and the like become entangled in a complicated manner, and furthermore, the loose wires and the like become tangled with the spool irregularly, making it impossible to operate the handle. Furthermore, when such a failure occurs, the problem is that repair work is extremely troublesome and time-consuming because the wires and the like are built into the flagpole.

Purpose of the invention The purpose of this invention is to solve the above-mentioned problems, and if the flag or flag attachment gets caught on the flagpole when lowering the flag, the wire, etc. will not be removed even if the handle is rotated in the direction of sending out the wire, etc. This means that there is no chance of loose wires getting tangled inside the flagpole or getting tangled irregularly around the spool, unlike conventional flagpoles, resulting in extremely low failure rates and ease of use. It is an object of the present invention to provide a convenient winding device for flag lifting wires, etc. on a flagpole.

Structure of the invention In order to solve the above problem, this invention includes a spool for winding wire, etc. attached to the lower end of the flagpole, and a spool rotating shaft, and between the spool and the rotating shaft, In the winding direction of the wire, etc., they are locked to each other, and in the sending direction of the wire, etc., when the tension due to the weight of the flag and flag holder is acting on the wire, etc., both are locked to each other, and the flag and the flag are fixed. The gist of the invention is a winding device for a flag lifting wire, etc., on a flagpole, in which a free rotating clutch is interposed to release the lock when the wire, etc. is not under tension due to the weight of the fixture.

Next, the operation of the flag lifting wire winding device 7 on the flagpole 1 will be explained.

First, to raise the flag F, the shaft portion 31 of the handle 30 is inserted into the hole in the cylindrical portion 10 of the frame 8, as shown by the solid line in FIG. As a result, the tip of the lock plate operating pin 41 is pushed up by the tapered guide surface 34 of the shaft portion 31 against the elastic force of the spring 39, causing the lock plate 37 to swing upward. The engagement between the plate 37 and the engagement gear 24 is released. Also at this time,
The engagement pin 2 is inserted into the groove 35 of the tip 31a of the shaft portion 31.
6 are fitted together. In this state, handle 30
When the flag F is rotated in a direction that raises the flag F, for example, clockwise, the rotating shaft 15 also rotates in the same direction as shown by arrow A in FIG. As a result, the rollers 17 of the clutch 16 are moved to the cam surface 22 side of the outer ring 20, the spool 14 and the rotating shaft 15 are locked, and the wire 2 is moved to the spool 14.
The flag F is wound up one after another, and the flag F rises. Then, when the flag F reaches the highest raised position, the handle 30 is pulled out. As a result, the lock plate actuating pin 41 is connected to the cylindrical portion 9 and the through hole 42 of the bush 27.
43, the lock plate 37 swings downward due to the elastic force of the spring 39, and its tip engages with the teeth of the engagement gear 24, so that the flag F is held in the raised state.

Next, to lower the flag F, the shaft portion 31 of the handle 30 is again inserted into the hole of the cylindrical portion 10 of the frame 8 and rotated in the opposite direction. At this time, the wire 2 is under tension due to the weight of the flag F and the flag fixture 4, and this tension urges the outer ring 20 of the clutch 16 to rotate in the direction of arrow B in FIG. The spool 14 and the rotating shaft 15 are in a locked state via a clutch 16. Therefore, by rotating the handle 30 in the opposite direction, the rotating shaft 15 and the spool 14 are rotated in the same direction, and the wire 2 is sent out in sequence, and the flag F is lowered. By the way, during descending, for example, if the flag F wraps around the flagpole 1 due to strong winds, etc., and the flag F or the flag attachment 4 gets caught, the outer ring 20 of the clutch 16 will be under tension as shown by the arrow B above. does not work, and rotation of the handle 30 causes the rotation shaft 15 to
only rotates in the direction of arrow C in the figure. As a result, each roller 17 comes off from the cam surface 22 and partially enters the roller housing recess 21 and rotates freely. Therefore, the rotating shaft 15 idles, the spool 14 does not rotate, and the wire 2 is unnecessarily fed out. can be prevented.

Note that when the flag F or the flag holder 4 is unhooked due to the flag F being wrapped around the wire 2, tension due to the weight of the flag F and the flag holder 4 is applied to the wire 2, so the flag F is re-attached.
can be unloaded.

In addition, in the above embodiment, the manual handle 3
0 is used to raise and lower the flag F, but instead of the manual handle 30, an electric tool may be used to raise and lower the flag F. Alternatively, a small motor may be incorporated to rotate the rotating shaft 15 in a desired direction.

Furthermore, the free rotation clutch 16 is not limited to that shown in the drawings, and may have other shapes and structures.

Effects of the invention As described above, the device for winding up a flag lifting wire, etc. for a flagpole according to this invention includes a spool 14 for winding a wire, etc. attached to the lower end of the flagpole 1;
It is equipped with a spool rotation shaft 15, and a spool 1
4 and the rotating shaft 15, the two are locked together in the winding direction of the wire 2, etc., and the tension due to the weight of the flag F and the flag fixture 4 is applied to the wire 2, etc. in the sending direction of the wire 2, etc. a free rotation clutch 16 which locks the flag F and the flag holder 4 to each other when the wire 2, etc.
is interposed, so if the flag F or the flag attachment 4 gets caught on the flagpole 1 when lowering the flag F, even if the handle 30 is rotated in the direction of sending out the wire 2, etc. This prevents loose wires 2, etc. from getting tangled inside the flagpole 1, and causing the spool 1
