The lifting roller 136 is capable of lifting up and down in the guide rail 133, the connecting rod 137 for connecting the lifting roller 136 and the upper coupling 131 through the long hole 135 is Is installed. Since the lifting roller 136 is constrained inside the guide rail 133, only the lifting roller 136 may move up and down along the guide rail 133, but does not move away from the guide rail 133.

The upper coupler 131 is coupled to the upper end of the banner 10, the upper coupler 131 and the lower coupler 132 generally has a structure of the coupling to install the banner 10, detailed description thereof is omitted. do.

The upper coupler 131 is raised or lowered between the upper and lower ends of the rotary frame 120 through the elevating drive unit 140, the elevating drive unit 140 is a winch installed on the lower side of the rotary frame 120. 141, the first to fourth guide rollers 146 to 149 installed on the rotating frame 120 and the upper coupling table 131, and the first to fourth guide rollers 146 to 149 once. And the other end includes a wire 150 fixed to the winch 141 and the upper coupling table 131, respectively.

The first and second guide rollers 146 and 147 are installed on the upper side of the rotating frame 120, the first guide roller 146 is installed to be located above the guide rail 133, the second guide roller ( 147 is installed on the other side of the upper side of the rotating frame 120 to be spaced apart from the first guide roller 146.

The third and fourth guide rollers 148 and 149 are spaced apart from each other so as to be adjacent to both ends at an upper side of the upper coupling table 131, respectively.

As described above, the wire 150 may be wound around the winch 141 to be wound or unwound according to the driving of the winch 141. The wire 150 may extend upward along the hollow 134 of the guide rail 133. After passing through the first guide roller 146 and the third and fourth guide rollers 148 and 149 and the second guide roller 147 sequentially, the other end is installed to be connected to the upper coupling table 131.

Therefore, when the winch 141 is driven so that the wire 150 is wound around the winch 141, the length of the wire 150 is shortened, and the upper coupling table 131 is lifted upward, and the wire 150 is unwound. When the winch 141 is driven, the entire length of the wire 150 is increased, and the first coupling roller 131 is lowered by the weight of the upper coupling rod 131, so that the first guide roller 146 and the third guide roller ( The distance between the 148 and the second guide roller 147 and the fourth guide roller 149 is far.

The winch 141 is installed below the rotating frame 120 to be positioned below the guide rail 133, and a fixing member 142 fixed to the rotating frame 120 and rotatable to the fixing member 142. Winding reel 143 is installed, the ratchet gear 144 is installed on the same central axis as the winding reel 143, and the fixing material 142 is installed in the ratchet gear 144, the winding reel 143 It includes a reel stopper 145 to prevent the rotation in the unwinding direction.

The ratchet gear 144 is installed in a direction opposite to the winding reel 143 with respect to the fixing member 142, and the rotation direction is limited by the reel stopper 145 to be rotated in only one direction.

That is, the reel stopper 145 is rotatably installed around the hinge shaft (not shown) on the fixing member 142, and one end of the reel stopper 144 is engaged with the teeth of the ratchet gear 144. In other words, the winding 150 prevents the wire 150 from rotating in the unwinding direction. The hinge shaft is provided with a torsion spring which elastically biases one end of the reel stopper 145 to rotate in the direction in which the reel stopper 145 engages with the ratchet gear 144, so that the reel stopper 145 is wound up by the reel stopper 145. 143 is limited to rotate in the other direction in which the wire 150 is released and may be rotated only in one direction in which the wire 150 is wound.

And the end of the rotary shaft of the winding reel 143 and the ratchet gear 144 is provided with a handle key 152 protruding to the outside of the rotating frame 120, the insertion groove 154 of the handle 153 carried by the operator ) By inserting the handle key 152 into the handle 153 in one direction by rotating the take-up reel 143 in one direction to raise the upper coupler 131 upwards.

When the upper coupling table 131 is to be lowered, the reel stopper 145 may be rotated about the hinge axis to be separated from the ratchet gear 144. When the reel stopper 145 and the ratchet gear 144 are separated, the upper coupling Since the force acts downward by the weight of the stand 131 and the banner 10, and the winding reel 143 is rotatable in the direction in which the wire 150 is released due to the separation of the reel stopper 145, the wire 150. The upper coupling stage 131 is lowered while the) is released.

The banner coupling unit 130 further includes a buffer support unit 160 for supporting the lower coupling table 132.

The buffer support unit 160 is to support the lower coupling table 132 to be able to ascend and move a predetermined distance in the vertical direction. If a wind such as a typhoon blows due to the characteristics of the banner 10, it is concave at a portion hit by the wind. As it clears, the force between the top and bottom is shortened.

When the distance between the upper and lower coupling bands 131 and the lower coupling band 132 supporting the top and bottom of the banner 10 is fixed at a constant, both the top and bottom are fixed when the banner 10 is hit by the wind. Therefore, it does not bend and breakage occurs.

The buffer support unit 160 of the present embodiment supports the lower coupling table 132 to be lifted upwards by a predetermined interval so that when the strong wind is hit by the lower coupling table 132, the banner 10 is bent and the damage occurs. Do not do it.

Two buffer support units 160 are installed to support both ends of the lower coupling table 132, respectively, the support rod 161 is fixed to the rotation frame 120 and extends upward, the support rod 161 It is installed to be elevated in the coupling bracket 163 connected to the base of the lower coupling table 132, the support plate 162 fixed to the upper end of the support rod 161, the support plate 162 and the coupling bracket ( It includes an elastic member 166 is installed between the 163.

The coupling bracket 163 is connected to the lower coupling table 132 and the first coupling member 164 extending in the vertical direction, and the second coupling member extending in the horizontal direction from the lower end of the first coupling member 164 ( 165, wherein the second coupling member 165 has a through hole formed therein so that the support rod 161 can pass therethrough, and the support rod 161 supports the coupling bracket 163 so as to pass through the through hole. The coupling bracket 163 is connected to the lifting rod 161 so as to be lifted and lowered by the mounting bracket 161.

And the elastic member 166 is a compression spring is applied, the support rod 161 is wrapped around the support plate 162 is fixed to the upper end of the support rod 161, the lower end of the second coupling member 165 is supported to elastically bias the coupling bracket 163 downward.

Therefore, when no external force is applied, the lower coupling table 132 is pulled downward by the elastic member 166 to tension the banner 10 so as not to be wrinkled, and strong wind blows the banner 10 to wind. When fitted, the coupling bracket 163 is elevated upward while pressing the elastic member 166 to provide a play that the banner 10 can be bent.

Hereinafter, the installation process and operation process of the banner 10 of the vertical banner post 100 according to the present invention will be described.

First, in order to mount the banner 10, the lower end of the banner 10 is connected to the lower coupler 132, and then the upper end of the banner 10 is fastened to the upper coupler 131. At this time, since the upper coupling table 131 is lowered to the lower portion of the rotating frame 120, the operator can install the banner 10 on the ground.

After connecting the upper and lower ends of the banner 10 to the upper coupler 131 and the lower coupler 132, the winding reel 143 is rotated in the direction in which the wire 150 is wound using the handle 153. Let's do it.

As the winding reel 143 rotates and the wire 150 is wound, the upper coupler 131 is lifted upward, and when the upper coupler 131 is lifted to the top of the rotation frame 120, the handle 153 is lifted. Remove from the handle (153) kill. Since the winch 141 is in the state where the reel stopper 145 is engaged with the ratchet gear 144, the upper coupling table 131 does not descend because the wire 150 does not rotate in the unwinding direction. At the time of replacement or removal of), the reel stopper 145 may be removed from the ratchet gear 144 to lower the upper coupling table 131.

When the strong wind blows in the state in which the banner 10 is installed, the banner 10 is subjected to wind resistance. At this time, the rotating frame 120 rotates in a direction receiving less wind resistance around the rotating shaft 121. At this time, the rotation angle is limited by the angle limit stopper 111.

Even when the rotation frame 120 is rotated, if the wind resistance is largely received, the coupling bracket 163 supporting the lower coupling table 132 moves upwards by a predetermined distance while pressing the elastic member 166, and the banner 10 Since it is possible to provide a deflectable play, the banner 10 may be prevented from being damaged by the wind.

When the external factors are removed, the rotating frame 120 is the door hinge structure as described above, so that the rotating shaft 121 is fastened to the main frame 110, the rotating frame 120 is returned to the initial position, the elastic member 166 As the coupling bracket 163 moves downward again by the elastic force of the lower coupling band 132, the banner 10 is flattened by maintaining an appropriate level of tension.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
