Description

FIELD OF INVENTION

The present invention relates to a rotation type flag hoisting pole that minimizes a rainwater surface adhesion area of a national flag (abbrev. to “flag”), more specifically, with key characteristics in which a “rainwater adhesion suppressing rod” is installed at a top end of a flag hanging steel bar provided with an upper “fixed structure” P and a lower “rotating structure” Q to execute a “rotation method” so as to inhibit a surface adhesion phenomenon of a large flag wetted with the rainwater while minimizing an adhesion area thereof, and at the same time, an adhesion part becomes a starting point for inducing ventilation into the adhesion part, whereby a speed of unfolding the large flag from the surface adhesion part thereof to the original state can be maximized.

There is provided an invention that, by assembling the upper “fixed structure” P and the lower “rotating structure” Q, a vertical moving body 100 comprising a rotational assembly part R is formed, and at the same time, the rotational assembly part R has dual functions, one of which is a “self-weight supporting function” to support the self-weight of the lower “rotating structure” Q with respect to the upper “fixed structure” P while the other one is a “rotation function” of the lower “rotating structure” Q, wherein a flag hanger as well as the lower “rotating structure” Q are simultaneously rotated according to the “rotation function” of the rotational assembly part R to prevent entwinement due to the “wind”, while enabling “self-weight supporting function” and “rotation function”, as well as “prevention of entwinement due to wind” to be efficiently and simultaneously attained by a simple structure of the rotational assembly part R.

In addition, there is provided an invention that the flag hanger rotated by the rotational assembly part R, which is an assembly of the upper “fixed structure” P and the lower “rotating structure” Q, may be formed in a strong steel bar shape unlike the conventional rope type hanger so that a flag binding part is not bent like a bow by the wind but always maintains flag binding in a vertical and straight line, thereby keeping more beautiful appearance of the flag.

Further, there is provided an invention that, in a state in which the vertical moving body 100 in a symmetrical structure is installed on a hoisting pole, an up-down rope is mounted on a single center vertical line V on which an inner diameter center vertical line M and a center vertical line N of the vertical moving body 100 coincide with each other so that the up-down rope becomes a symmetrical center line of the vertical moving body 100, and thus the up-down rope and the vertical moving body 100 move up and down simultaneously, whereby up-down movement of the vertical moving body 100 always retains a balance without eccentricity while being efficiently performed.

BACKGROUND OF INVENTION

In general, lifting and lowering a flag along a flag hoisting pole are performed by a rope in an up-down movement manner.

A typical rope up-down movement method is disclosed in Korean Registered Utility Model No. 20-0246070 (referred to as prior art 1). The up-down rope is exposed to the outside of the hoisting pole as shown in FIG. 1.

First, looking at common problems of the rope up-down movement method is as follows.

As shown in FIG. 1, the flag is hung on an up-down rope provided outside the hoisting pole, and the rope is bent like a bow by the wind. As a result, the flag hanging on the rope may also be bent like a bow along with the rope. Since a vertical line of the flag is bent in a bow shape of the rope, there is a problem in that appearance of the flag deviating from the vertical line is ugly. Such a phenomenon due to the above problem is conspicuously exhibited on the flag hoisting pole at an international event site where many national flags are hoisted in one place.

Korean Patent Laid-Open Publication No. 10-2019-0011149 (referred to as prior art 2) disclosed a method of suspending a flag on a horizontal flag hanger rod 211 as shown in FIG. 2 in a horizontal direction while taking a rope up-down mode instead of the method for hanging a flag on an up-down rope vertically.

Since the prior art 2 did not adopt a structure in which the flag is hung on the up-down rope, there is no problem in that the vertical line of the flag is bent like a bow as in the prior art 1. However, as shown in FIG. 4, a problem of the flag being entwined around the horizontal flag hanger rod 211 is unavoidable.

Herein, both the prior arts 1 and 2 take a rotating method as well as a rope up-down mode. That is, both of the prior arts 1 and 2 disclosed a horizontal rotation method that rotates horizontally with respect to the vertical line of a hoisting pole. Accordingly, in the prior art 1, the flag hanging vertically on the rope may rotate horizontally with the wind, thereby preventing the flag from being entwined around the hoisting pole. On the other hand, according to the prior art 2, the flag has a structure that is hung on a strong horizontal flag hanger rod as shown in FIG. 2 and thus may not be wound around the hoisting pole. Therefore, the horizontal rotation method of the prior art 2 has nothing to do with the entwinement around the hoisting pole, however, this horizontal rotation method also does not prevent the flag from being entwined around the horizontal flag hanger rod 211. This is because, with respect to the horizontal flag hanger rod 211, a vertical rotation method is required to prevent the entwinement of the flag around the horizontal flag hanger rod 211. Furthermore, the horizontal rotation method of the prior art 2 has absolutely nothing to do with the prevention of entwinement of the flag around the horizontal flag hanger rod 211.

Next, Korean Registered Patent No. 10-0303045 (referred to as prior art 3) disclosed that a rotation method in a rope up-down mode wherein a rope is located inside a hoisting pole (see FIG. 3).

The prior art 3 relates to a rotation method using upper and lower wind direction rotational rings 14, 14′ so as to prevent a flag from being entwined around a hoisting pole. However, this is a structure in which the flag is hung on the upper and lower wind direction rotational rings 14 and 14′. However, there is no separate means for holding the flag between the upper and lower wind direction rotational rings 14 and 14′. That is, there is only the flag between the upper and lower wind direction rotational rings 14 and 14′. In this case, the structure has a margin width through which the upper and lower wind direction rotational rings 14 and 14 can slid up and down. Due to such an up-down sliding margin width, there is a problem in that, as the flag is bent like a bow by the wind as shown in FIG. 3, appearance of the hoisted flag becomes ugly. At this time, a sliding width of the lower wind direction rotational ring 14′ is between a third projection 12″ and a second projection 12′ while a sliding width of the upper wind direction rotational ring 14 ranges from a first projection 12 up to the top.

Further, the above structure is also provided with an up-down roller along with the up-down rope in a narrow inner diameter of the hoisting pole, wherein the up-down rope disposed in the inner diameter has no special function other than serving to move a lifting member 130 up and down.

Meanwhile, all of the prior arts 1, 2 and 3 adopt a rotation method for preventing entwinement around a hoisting pole due to the wind. However, there is no description of the issue of “surface adhesion of a large flag wetted with the rainwater”. The larger the area of the large national flag wetted with rainwater, the much slower a rate of restoration of the flag to its original state. Even in such state, the large flag could not be lowered. This is because the rope does not work downward. Accordingly, there is a problem in that the unsightly appearance of the hoisted flag has no choice but to continue as it is in that state.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF INVENTION

The configuration of the flag hoisting pole in a rotation manner to minimize a rainwater surface adhesion area of a flag according to the present invention will be described in detail with the accompanying drawings as follows.

The vertical moving body 100 may be an assembly comprising an upper “fixed structure” P and a lower “rotating structure” Q.

With respect to the upper “fixed structure” F, the lower “rotating structure” Q is a rotational structure.

The lower “rotating structure” Q is divided into upper and lower rotating parts U and D based on a horizontal connection part 156. Although the actual lower “rotating structure” Q is a single integrated rotational member, it has been divided as above for convenience of explanation.

First, the rotational assembly part R will be described as follows (see FIGS. 7 and 8).

The rotational assembly part R may be an assembly comprising the upper “fixed structure” P and the lower “rotating structure” Q.

In other words, the rotational assembly part R may be an assembly comprising a receiving part 116 of the upper “fixed structure P and an upper rotating part U of the lower “rotating structure” Q, while a lower rotational part D thereof is disposed on an extension of the upper rotating part U. The upper and lower rotating parts U and D are included in the lower “rotating structure” Q.

The upper rotating part U of the rotational assembly part R may be a single connection part in which the press rotary plate 152, a press supporting rod 153, a horizontal connection rod 154, and a vertical connection rod 155 are sequentially connected.

The press rotary plate 152 and the press supporting rod 153 welded and fixed thereto among the upper rotating part U may be inserted and assembled in the receiving part 116 of the “fixed structure” P.

With respect to the upper rotating part U, the lower rotating part D may be a flag hanger 157 in a steel bar shape comprising a “circumferential vertical structure F”.

The “circumferential vertical structure F” of the flag hanger 157 is a steel bar having the same diameter with respect to the center vertical line N of the vertical moving body 100, and may have a symmetrical structure consisting of a flag hanging steel bar 157a and a supporting steel bar 157b. The “circumferential vertical structure F” may be fixed through welding with a plurality of horizontal support rotational rings 158. The flag hanging steel bar 157a may be a steel bar to which the flag is bound. The supporting steel bar 157b may be a support member to constitute the “circumferential vertical structure F” of the flag hanger 157 together with the flag hanging steel bar 157a. The number of the support members is preferably four (4) in order to form a symmetrical structure with respect to the center vertical line N of the vertical moving body 100. As the four support members, the flag hanging steel bar 157a and the supporting steel bar 157b are preferably steel bars having the same diameter made of the same solid material for symmetry.

The rainwater adhesion suppressing rod 159 may be installed and fixed at a top end of the flag hanging steel bar 157a.

The up and down rotating parts U and D may be interlinked to rotate at the same time.

With respect to the upper “fixed structure” P, the lower “rotating structure” Q may be rotated by the rotational assembly part R.

According to the wind direction, the lower “rotating structure” Q (“the flag hanger 157”) may rotate simultaneously with rotation of the upper rotating part U of the rotational assembly part R.

The rotational assembly part R may perform dual functions.

One of the functions is “self-weight supporting function” that supports the self-weight of the lower “rotating structure” Q with respect to the upper “Fixed structure” P, while the other is “rotation function” to rotate the lower “rotating structure” Q.

The rotational assembly part R is preferably provided with a circular bearing 116a in the receiving part 116 since the press rotary plate 152 of the upper rotating part U rotates within the receiving part 116 of the upper “Fixed structure” P.

Second, the center vertical line N of the vertical moving body 100 will be described in detail as follows (see FIGS. 6, 7 and 8).

The vertical moving body 100 has a symmetrical structure with respect to the center vertical line N.

The upper “fixed structure” P and the lower “rotating structure” Q may also have a symmetrical structure with respect to the center vertical line N.

Further, the center vertical line N of the ascending and descending vertical moving body 100 may coincide with the inner diameter center vertical line M of the hoisting pole having the same outer diameter.

The flag hanger 157 of the “circumferential vertical structure F” may form a symmetrical structure with respect to the center vertical line N.

The horizontal support rotational ring 158 is a “weld-fixed member” of the “circumferential vertical structure F” and, at the same time, a “horizontal support member” for the lower “rotating structure Q”.

A large flag is bound to only the flag hanging steel bar 157a on which the rainwater adhesion suppressing rod 159 is installed, so as to always maintain a vertical straight line, thereby having beautiful appearance.

Third, the rainwater adhesion suppressing rod 159 will be described in detail as follows (see FIGS. 6, 7 and 8).

The rainwater adhesion suppressing rod 150 installed and fixed at the top end of the flag hanging steel bar 157a is a horizontal member made of a strong steel bar in order to support the weight of a large national flag wetted with the rainwater while inhibiting surface adhesion thereof. As shown in FIG. 8, it is preferable to install an inclined reinforcing bar 159a that reinforces the horizontal rainwater adhesion suppressing rod 159.

Herein, the rainwater adhesion suppressing rod 159 is only a member for inhibiting surface adhesion, but is not a flag hanger rod for hanging the national flag. This is because the flag is already bound on the flag hanging steel bar 157a of the vertical flag hanger 157.

Main functions of the rainwater adhesion suppressing rod 159 are to inhibit surface adhesion of a large (national) flag wetted in the rain, to minimize an adhesion area, and at the same time, to provide and adhesion part as a starting point for inducing ventilation into the adhesion part (see FIG. 1).

In order to implement the above functions, a length of the rainwater adhesion suppressing rod 159 is preferably ⅛ to ¼ of a flag width in a transverse direction.

If the length of the rainwater adhesion suppressing rod 159 exceeds ¼ of the flag width, compared to an efficient advantage of providing a starting point for inducing ventilation into the adhesion part with respect to the surface adhesion of a large flag wet in the “rain”, it entails greater disadvantages of harmful effects such as wind pressure applied to the large flag unfolded (or spreading) due to the rainwater adhesion suppressing rod 159, in particular, strong wind pressure such as typhoons.

Among such harmful effects, the wind pressure applied in a state where the large flag is unfolded by the vertical flag hanging steel bar 157a as well as the horizontal rainwater adhesion suppressing rod 159 may be unavoidable. Specifically, as the wind pressure is continuously applied and as the length of the rainwater adhesion suppressing rod 159 increases, a magnitude of the wind pressure may also increase. Eventually, the flag hanging steel bar 157a as well as the rainwater adhesion suppressing rod 159 cannot withstand the pressure and be damaged, hence causing harmful effects of stopping operation of the vertical moving body 100.

Further, when the length of the rainwater adhesion suppressing rod 159 is less than ⅛ of the flag width, a starting point for inducing ventilation into a surface adhesion part with respect to the surface adhesion of the large flag itself wet in the “rain” is very little provided, therefore, a speed of unfolding the flag to its original state also does almost not exist, thus making it inefficient.

Fourth, a relationship between the inner diameter center vertical line M of the hoisting pole, the center vertical line N of the vertical moving body 100 and the up-down rope will be described in detail as follows (see FIGS. 6, 7 and 8).

In a state in which the vertical moving body 100 is installed on the hoisting pole, a center line on which the inner diameter center vertical line M of the hoisting pole and the center vertical line N of the vertical moving body 100 coincide with each other is specifically called a single center vertical line V.

The hoisting pole and the vertical moving body 100 are symmetrical with respect to the single center vertical line V.

Further, the up-down rope is also mounted and positioned on the single center vertical line V.

The vertical moving body 100 is symmetrical with respect to the single center vertical line V and moves vertically along the up up-down rope, therefore, may be characterized in that the vertical moving body 100 can always be balanced without eccentricity while efficiently moving up and down.

Fifth, the binding of a large flag with the flag hanging steel bar 157a and the rainwater adhesion suppressing rod 159 will be described in detail as follows.

A longitudinal direction of the flag may be tied together with the flag hanging steel bar 157a using a connection iron string C which penetrated through a binding hole S and thus be firmly bound. The binding of the rainwater adhesion suppressing rod 159 in the transverse direction of the flag may also be bound in the same manner as described above. Since such a binding method is only typical and not special in the art, any conventional binding method may also be applied.

Sixth, ascending and descending (“elevation”) of the vertical moving body 100 to which the large flag is bound will be described in detail as follows (see FIGS. 6, 7 and 8).

The elevation of the large flag may be performed by moving the flag vertically using the up-down rope 160 on the single center vertical line V.

The up-down rope 160 on the single center vertical line is a vertical line from a handle bobbin 174 to the direction switching roller 176. A switching extension for the direction-switched rope may be fixed on an inner vertical part 112 of the upper “fixed structure” P. At this time, another connection rope may be added in parallel to the extension of the switched rope. Specifically, two parallel rope switching extensions may be symmetrically fixed to the inner vertical part 112 of the upper “fixed structure” P with respect to the single center vertical line V and a center line of the direction switching roller 176.

Seventh, other configurations will be described in detail as follows (see FIGS. 10 and 11).

First, the up-down rope 160 is wound around a typical winder device 174a and is lifted by the handle 174. Then, the up-down rope 160 is fixed by a break button 174b. By means of a stopper projection 171 mounted on the uppermost end of the hoisting pole 170, the vertical moving body 100 may no longer ascend.

Second, it is preferable to install a noise prevention member G at friction contact surface positions of the vertical moving body 100 sliding on the hoisting pole 170, for example, the inner vertical part 112 of the upper “fixed structure” P, the horizontal support rotational ring 158 of the flag hanger 157, etc.

Third, a large flag may be bound to the flag hanging steel bar 157a by the connection iron string C passing through the binding hole S of the flag.

Forth, the installation of the vertical moving body 100 on the hoisting pole may be implemented by a general installation method. For example, one of the methods is an assembly method or a welding method. The assembly method is a method that manufactures the vertical moving body 100 in a symmetrical structure with respect to the center vertical line N as half-finished products at the factory, and then, assembles and installs the products in the field. The welding method is a method that welds and fixes the half-finished products in the field. The general installation method may involve two pre-requisites such as: (1) a condition in that the center line N of the vertical moving body 100 installed on the hoisting pole coincides with the single center vertical line V; and (2) a condition in which the elevation of the upper moving body 100 is always implemented in a sliding manner without eccentricity. As long as the above two conditions are satisfied, any installation method may be used.

As describe above, since the up-down rope 160 is mounted on a single center vertical line V and the vertical moving body 100 ascends and descends with respect to the single center vertical line V, sliding the vertical moving body 100 up and down may be more balanced while being efficiently performed. Further, by the rainwater adhesion suppressing rod 159, it is possible to inhibit surface adhesion of a large flag wet in the rain while minimizing an adhesion area thereof. In addition, according to the present invention, an adhesion part may become a starting point for inducing ventilation into the adhesion part, whereby the present invention may be useful with a characteristic in that a speed of unfolding the flag to its original state is maximized.
