Description

Flag stick with anti-winding function

The present invention relates to a national flag pole having an anti-winding function, and more specifically, by improving the structure so that the hoisted national flag does not become rolled up by the wind in a state in which it is blown by the wind, even when wind occurs It's about the technology that made the flag stay open.

In general, the national flag pole corresponds to the composition for raising the national flag symbolizing the country in events commemorating national holidays or various purposes.

The national flag installed on the flag stick is made of a fabric material, so wind does not pass through it and resistance is generated, so it can be easily deformed. It has no structure.

Due to this structural problem, if the wind blows a lot or the wind direction is irregular, the national flag will be in the form of being wound around the national flag pole. In this way, the type of national flag cannot be identified from the outside, and thus the original role of the national flag stick cannot be performed. In addition, the national flag pole with the national flag wound has a problem in that it harms the aesthetics and impairs the status of the national flag.

Therefore, for the flagpole on which the flag is wound, the manager directly climbs up to the position where the flag is hoisted and unfolds the wound part, or if it is too high, a tool such as a stick is used. However, if the wind continues to blow, there is a problem such as rewinding even if the wound flag is unfolded.

As a technology to solve the problem of winding the national flag, in Utility Model Registration No. 20-0353328 (flag hoisting device), a rotating flagpole with a pipe-shaped slide forcedly inserted into the upper part of the fixed flagpole to which the flagpole is attached is inserted and rotated. In a known flag hoisting device that fastens a stopper that supports sliding so that the flagpole can rotate smoothly along the outer circumference of the fixed flagpole to the lower end of the fixed flagpole, a tightening device for slidingly supporting the smooth rotation of the rotary flagpole and rotatably coupled to the guide ring; a rotary flagpole formed to have a detachable device in the form of an upper slide having a fitting ring formed thereon, and a detachable ring connected to the fitting ring formed on one side of the lower slide by a rubber band ring; A technology configured to be used by directly attaching and detaching a flag and an auxiliary symbol to the detachable ring and the guide ring through a fastening hole is disclosed.

The prior art is a technique to prevent the national flag (flag) from being wound by being configured to rotate the flagpole, but since the upper and lower positions are fixed in the part where the national flag is installed, the wind As a result, a winding phenomenon may occur due to the deviation of the force transmitted to the upper and lower parts of the flag.

The present invention has been devised to solve the above problems, so that the upper and lower portions of the national flag are installed to be rotatably installed, but the position of the rotated portion is not fixed and can be moved according to the wind direction. The purpose of the present invention is to provide a national flag stick having an anti-winding function that can effectively prevent the warping phenomenon compared to the prior art by configuring it to improve the aesthetics of the flag stick and eliminate the hassle of the manager.

The present invention provides a flagpole made of a rod-like shape so as to be stretchable in the longitudinal direction, an upper fixture fixedly installed at a specific position on the upper part of the flagpole, an upper ring rotatably coupled to the upper fixture to connect the upper end of the national flag; A lower fixture installed on the flag object at a position spaced apart from the installation position of the upper fixture in the lower direction, and a lower ring rotatably coupled to the lower fixture to connect the lower end of the national flag; It is characterized in that it is installed in a vertically movable form.

In addition, at the upper and lower ends of the upper and lower fixtures, support jaws for limiting the upper and lower movements of the upper and lower rings are respectively formed, and between the support jaws, the upper and lower rings are rotatably coupled to the outer circumferential surface. Cylindrical part; characterized in that it is formed.

In addition, the support jaw interval of the upper fixture is formed to have a length corresponding to the thickness of the upper ring, so that the upper ring does not move in the vertical direction, and the support jaw interval of the lower fixture is formed to be longer than the thickness of the lower ring, It is characterized in that the lower ring is configured to move in the vertical direction.

In addition, the support jaws of the upper and lower fixtures are configured in a detachable form, so that the upper and lower rings are easily coupled.

In the present invention, the upper ring to which the upper part of the national flag is coupled is rotatably coupled, and the lower ring to which the lower part of the national flag is coupled is rotatably coupled to enable vertical movement, thereby minimizing the winding phenomenon when the wind blows, In particular, when the wind blows upward, since the lower ring rotates upward in the direction of the wind, little rotational resistance occurs, thereby reducing the possibility of occurrence of rotational deviation.

Flagpole 100 having an anti-winding function of the present invention As shown in FIGS. 1 and 2, the flagpole 100 is formed so as to be stretchable in the longitudinal direction, and the upper fixture is fixedly installed at a specific position on the upper part of the flagpole 100 ( 200), an upper ring 300 rotatably coupled to the upper fixture 200 to which the upper end of the national flag A is connected, and a flagpole spaced apart from the installation position of the upper fixture 200 in the downward direction. (100) a lower fixture 400 installed on the, and a lower ring 500 that is rotatably coupled to the lower fixture 400 and connected to the lower end of the national flag (A); Doedoe including, the lower ring (500) is characterized in that it is installed in a vertically movable form.

Most of the prior art tried to obtain the effect of preventing the winding of the flag by adding only a rotation function. However, depending on the direction and strength or rotational resistance of the wind, rotational deviation of the upper and lower portions may occur, which caused a problem in which the national flag is wound. Through the present invention, the rotational deviation of the upper and lower portions is minimized and It is possible to minimize the winding problem by configuring the fixed position of the flag to be flexibly changed according to the direction.

A characteristic of the present invention is that the upper part and the lower part to which the national flag (A) is fixed are rotatably installed, respectively, the upper part is installed to be rotated without vertical movement, and the lower part is installed so that rotation and vertical movement are possible. Even if the flag (A) rotates according to the influence of the wind, it is possible to rotate or move freely in the vertical direction according to the situation, thereby preventing the phenomenon of the flag (A) being wound around the flagpole (100).

As shown in the drawing, the flagpole 100 of the present invention is configured to be stretchable in the vertical direction. That is, the length can be adjusted in the form of drawing out or retracting rods having different diameters in multiple stages, which corresponds to the conventional expansion and contraction control configuration, so a detailed description will be omitted. In addition, the head member 110 is finally fitted to the upper end of the flagpole 100 .

The upper fixture 200 and the lower fixture 400 correspond to a configuration that is fixedly installed on the flagpole 100 . The distance between the upper fixture 200 and the lower fixture 400 is preferably installed to match the size of the flag A in the vertical direction. The material of the upper fixture 200 and the lower fixture 400 may be a metal material or a synthetic resin material, and the coupling method is such that the inner diameter of the upper fixture 200 and the lower fixture 400 is almost the same as the outer diameter of the flagpole 100 It is preferable to install by force fitting.

The upper fixture 200 and the lower fixture 400 are fixed without rotating once installed, and their positions are also fixed, but they can be separated or removed or replaced if necessary. And the upper and lower ends of the upper and lower fixtures 200 and 400, as shown in FIGS. ) are formed, respectively, and between the support jaws 600, the upper ring 300 and the lower ring 500 are rotatably coupled to the outer circumferential surface of the cylindrical portion 700; the configuration is formed.

The support jaw 600 of the upper fixture 200 is formed with a length corresponding to the thickness of the upper ring 300, so that the upper ring 300 does not move in the vertical direction, and the lower fixture 400 The spacing of the support jaws 600 is formed to be longer than the thickness of the lower ring 500 , and the lower ring 500 is configured to move in the vertical direction within the range of the support jaws 600 . That is, by making the section in which the cylindrical part 700 of the lower fixture 400 is formed longer than the section in which the cylindrical part 700 of the upper fixture 200 is formed, the vertical movement of the lower ring 500 is free.

The upper ring 300 and the lower ring 500 of the present invention are configured to be rotatably coupled to the upper holder 200 and the lower holder 400 as described above. And the shape of the ring portions 310 and 510 to which the upper end and the lower end of the national flag (A) are coupled, respectively, may be formed in various ways, and in the present invention, the shape of the portion coupled with the national flag (A) is not limited.

In addition, the support jaw 600 of the upper fixture 200 and the lower fixture 400 is configured in a detachable form as shown in FIGS. 4 to 5, so that the upper ring 300 and the lower ring 500 are easy It is good to have it tightly coupled. At this time, the detachable structure may be formed in a form to be coupled by inserting in an uneven [凹凸] form as shown in the drawings.

Of course, without separating the support jaw 600, the upper ring 300 and the lower ring 500 can be configured in a "C" shape and fitted in a form that is spread from one side, but in the separation and coupling process, the upper ring 300 and the upper ring 300 and In order to prevent deformation of the lower ring 500, it is preferable to couple the support jaw 600 in a separated state as described above.

The supporting jaw 600 of the present invention may be formed in both the upper and lower portions as described above, but may be formed only in the lower portion in some cases. The reason is that since the head member 110 is coupled to the upper portion of the upper fixture 200, the head member 110 can support so that the upper ring 300 is not separated to the upper part, and the lower fixture 400 is long. Even if the lower ring 500 temporarily rises through the formed cylindrical portion 700 , it can be supported by the supporting jaw 600 formed in the lower portion by descending again by gravity.

Also, in the present invention, as shown in FIG. 6 , the slit portion 800 vertically cut may be formed on one side of the upper fixture 200 and the lower fixture 400 . As the slit portion 800 is formed, the flagpole 100 of the upper and lower fixtures 400 is temporarily widened in the process of coupling, so that the coupling can be made more easily. It can be fixed with strong pressure.

It is preferable that an adhesion member (not shown) made of rubber and material is coupled or coated on the inner peripheral surfaces of the upper fixture 200 and the lower fixture 400 for strong fixing force.

7 to 8 show another embodiment of the upper ring 300 and the lower ring 500 of the present invention, the inner surfaces of the upper ring 300 and the lower ring 500 are not in full contact, only a part of the contact. It is constructed so as to minimize the load caused by friction during rotation. That is, as shown in FIG. 7 , a plurality of arc portions 910 are repeatedly formed along the circumference so that only the portion to which the arc portion 910 is connected is in contact with the upper fixture 200 or the lower fixture 400 , or in FIG. As shown, the protrusion 920 may be formed on the inner side of the upper ring 300 and the lower ring 500 so that only the protrusion 920 is in contact.

In the case of the conventional rotary flagpole, when the wind blows upward, resistance occurs in the direction of rotation, causing a rotational deviation between the upper and lower portions to cause a winding phenomenon. As the lower ring 500 rotates while rising upward, little rotational resistance is generated, thereby reducing the possibility of occurrence of rotational deviation.

In addition, FIG. 9 shows another embodiment of the lower ring 500 in the present invention, and corresponds to a configuration in which a weight 520 is further formed on the opposite side of the ring portion 510 formed in the lower ring. The reason for forming the weight 520 in this way is,

When the wind disappears while the lower ring 500 is temporarily raised by the wind, the lower ring 500 is vertically descended along the lower fixture 400 . At this time, since the national flag (A) is coupled to the ring portion 510 and the center of gravity is relatively biased toward the ring portion 510 , the lowering action of the lower ring 500 may not be smooth. Therefore, by forming a weight 520 with an appropriate weight in consideration of the weight of the ring portion 510 and the load of the flag on the other side of the ring portion 510, it is not biased toward the ring portion 510 side of the lower ring when descending. A stable descent can be induced.

And, since the upper ring 300 is not configured to act upward and downward, it is not necessary to apply the weight 520 to the upper ring.

10 to 11 correspond to a configuration showing an embodiment in which the head member 110 is not coupled to the flagpole 100 but is coupled to the upper fixture 200 by changing the shape of the upper fixture 200 of the present invention. That is, the upper fixture 200 is coupled to the upper end of the flagpole 100 , and the head member 110 is coupled to the upper part of the upper fixture 200 .

10 shows the head member 110 is formed to be larger than the diameter of the upper fixture 200, the head member 110 is fitted to the outside of the upper fixture 200, Figure 11 is the head member 110 is It is formed to be smaller than the diameter of the upper fixture 200 , so that the head member 110 is fitted inside the upper fixture 200 .

Although the present invention has been described above with reference to the above embodiments, it goes without saying that various modifications are possible within the scope of the technical spirit of the present invention.
