Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flag pole for displaying various flags and flags (hereinafter referred to as flag flags), and more particularly, to raising and lowering the flag flags. It relates to a flag flag pole with an improved rope handling structure. 2. Description of the Related Art At shrines and the like nationwide, a plurality of banners are set for festivals, ceremonies, and the like. Such banners are elongated banners that are set up through wooden poles, and in accordance with these events. It was common for people in town to participate. After the festival was over, the flags and rods were cleared and stored until the next festival came. However, in recent years, people have not gathered to set up the flag because of the shortage of workers, and some people have adopted a style in which the metal flag flag pole is kept up all year and only the flag is raised and lowered. [0003] An example of this type of flag flag pole is shown in FIG. In the figure, a vertically long banner 4 is displayed, and a head 2 is attached to an upper end of a columnar pole body 1 erected on the ground. The head 2 has a base 21 having the same column shape as the pole body 1 and is rotatably connected to the upper end of the pole body 1. The head base 21 is provided with a support arm 22 projecting in the horizontal direction at an intermediate position. One end of the wire rope 3 hangs down from a position close to the tip of the support arm 22, and this and the suspender 41 are connected. Join. The hanging member 41 is a rod-like body having a fixed length, and is connected to the wire rope 3 at the center of the upper surface thereof, and locks a ring piece 42 provided on the upper side of the flag flag body 4 at left and right positions. The flag flag body 4 suspended by the hanging tool 41 is provided with a ring-shaped restricting tool 43 (referred to as milk) at a plurality of vertical positions on one side edge, and the tip ring portion is fitted to the pole body 1. To prevent the flag flag body 4 from swaying. The other end of the wire rope 3 has guide rollers 71,
72, the other end of the rope extends downward along the outer periphery of the pole body 1, reaches a winch 6 provided at the base end of the pole body 1, and is wound around the drum. Thus, the operation lever 66 of the winch 6 is operated to rotate forward and reverse, and
By winding or pulling out the wire rope 3, the banner 4
Was raised and displayed, or lowered to accommodate the banner. Further, when the flag flag body 4 receives a cross wind, the head 2 and the support arm 22 are turned to avoid the wind. [0004] However, in the flag flag pole, the support arm 1 turns in response to the cross wind received by the flag flag body 4, and the wire rope 3 is twisted with the turning. When this occurred repeatedly, the wire rope 3 was fatigued and durability was remarkably reduced. In addition, since the wire rope 3 usually hangs down along the outer peripheral surface of the pole body 1, the wire rope 3 shakes due to the wind, and comes into contact with the pole body 1 to generate unpleasant metal discomfort. Emitted. The sound of such metal-metal collisions resonated especially in a quiet precinct and caused a noise problem. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a flag flag pole for improving the service life of a rope for raising and lowering a flag flag and eliminating the harsh noise caused by the rope. I do. A flag pole according to the first aspect of the present invention is provided with a head that is rotatable around a pole axis at an upper end of a pole body that is erected, and is suspended from the head. One end of the rope is fixed to the upper edge of the flag flag body, while the other end of the rope is inserted through the pole body into the cylindrical pole body through the head, and on the way through the connecting member. To reach the base end of the lower pole body, and the connecting member has one connecting tool and another connecting tool, and the one connecting tool is formed into a cylindrical body which is closed at one end. Separated at the end of the connecting member at the closed end
While one end forming wear of the upper side rope and lower rope being, without to hold a ring-shaped thrust bearing at its inner peripheral wall, and the other connector,
Wherein the thrust bearing is formed into a columnar body having a flange portion which abuts the support, by binding the other end of said upper ropes and lower rope end face of the columnar body, the coupling member
The upper rope and the lower rope which are separated from each other are connected so as to be rotatable relative to each other. Here, the term "rope" refers to a general term for tethers and ropes, and may be any of a yarn net or a steel rope (wire rope).
The “connecting member” may have any structure as long as it connects the upper rope and the lower rope so as to be relatively rotatable relative to each other. According to the flag pole of the first aspect of the present invention, when the flag flag body receives a crosswind, the head rotates so as to avoid the wind. The rope is twisted accordingly. However, the rope is separated into an upper rope and a lower rope by a connecting member on the way, and the two are connected to each other so as to be rotatable relative to each other, so the upper rope fixed to the flag body through the head from the connecting member. Can rotate integrally with the head independently of the lower rope, and the rope will not be twisted. The rope tension is transmitted between the upper rope and the lower rope via the connecting member. Also, since the rope passes through the inside of the pole body, it is not affected by wind. [0010] By Bearings member, the relative rotation of the both connector is reliably assured. Further, the with coupling member is achieved in a compact, by the thrust bearing, the tension of the upper rope and lower rope is transmitted reliably to each other. FIG. 1 shows an example of a flag flag pole according to the present invention. In the figure, the total length of the flag flag pole is about 13 m, and the pole body 1 is vertically erected on the ground with its lower end buried and supported in the ground.

Is a horizontal sectional view thereof. In the pole body 1, a guide roller 74 is provided on a support shaft 13 that crosses the pole horizontally, and the lower rope 32 reaching from above is suspended by the guide roller 74 and changes its direction in the horizontal direction. Body 1
Can be wound around the drum 61 of the winch 6 located at the side of the winch 6. The guide roller is provided with a bar 73 for preventing the rope from falling off in the vicinity of the outer periphery thereof. The winch 6 is mounted on a mounting plate 63 projecting laterally from the pole body 1. The mounting plates 63 are fixed to both side surfaces of the pole body 1 and extend in parallel to the leg plates 63.
1, 632 and support plates 633, 634 installed in parallel between the leg plates 631, 632. The casing 62 of the winch 6 is bent into a substantially U-shape that opens upward and is fixed on the support plates 633 and 634. The drum 61 is rotatably supported between both side walls. The drum 61 can be rotated forward and backward by an operation lever 66 attached to a rotation shaft 65 protruding from the gear cover 64. The components described above are all made of stainless steel except for a part of the packing and the guide ring 212. (2) Operation and effect of the flag flag pole In the flag flag pole having the above-mentioned structure, when the operation lever 66 of the drum 61 is operated in the normal or reverse direction, the drum 61 rotates and the lower rope 32 is wound up. Or pay out.
When the lower rope 32 is wound on the drum 61, the lower rope 32 in the pole body 1 moves downward, and the connecting member 5
The upper rope 31 which has been subjected to the pulling force via the above also moves downward. Thus, hanger 4 1 moves upward, the hanging member 41
The flag flag body 4 fixed on is raised and displayed. On the other hand, when the lower rope 32 is unreeled from the drum 61, the flag flag body 4
Is lowered by its own weight, and the hanging tool 41 and one end of the upper rope 31 are also lowered, so that the banner can be removed from the hanging tool 41 and stored and stored. On the other hand, when the displayed flag flag body 4 receives a crosswind, the head body 21 and the support arm 22 are caused by the wind.
Turns, and the upper rope 31 also rotates integrally. However, since the lower rope 32 is connected to the upper rope 31 so as to be relatively rotatable by the connecting member 5, even if the upper rope 31 rotates, the rotational force is not transmitted to the lower rope 32. Only the upper rope 31 rotates freely, and the lower rope 32 is stationary. That is, since the wire rope 3 is separated by the connecting member 5 into the upper and lower ropes 31 and 32 that can rotate relative to each other, the wire rope 3 is prevented from being shortened in life due to fatigue without twisting. . The entire wire rope 3 is the pole body 1
Since it is inserted into the inside, it does not shake due to the wind and comes into contact with the pole body 1 to resonate unpleasant metal sounds such as callan and callan. By inserting the wire rope 3 into the pole body 1, the wire rope 3 is protected from wind and rain, and no rust or the like is generated. Furthermore, since all are made of stainless steel except for some resin packings, the mechanical strength is sufficient and the durability is excellent, and the life is long even when exposed to wind and rain. The present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the present invention depending on the purpose and application. Pole body 1, head 2, wire rope 3,
The shape, size, material, and the like of the flag flag body 4, the connecting member 5, and the like can be appropriately selected according to the purpose. The structure of the connecting member is not limited to that of the above-described embodiment, but may be any as long as it connects the upper rope and the lower rope so as to be rotatable relative to each other. In addition, although the banner is described in the embodiment, the invention can be applied to the display of a flag such as a national flag in an Olympic sport, a national sport, and the like. As described above, the flag pole of the present invention is
The service life of the rope for raising and lowering the flag and flag can be greatly extended, and further, the unpleasant noise generated when the rope is shaken and comes into contact with the pole body can be eliminated.
