The insertion groove 131a is more deeply formed than the anchoring groove 131b, and a through-hole 131c is formed at one side of the insertion groove 131a and communicates with the insertion groove 131a. In addition, the rectangular frames 131 of the case sections 130a and 130b are formed with hinge insertion grooves 131d at the top and bottom ends of the other pair of adjacent lateral edges thereof, respectively.
As shown in
Meanwhile, the case sections 130a and 130b are provided with locking device 150 (shown in
As shown in
In addition, in order to prevent the elongated leg 151 from being inadvertently released from the insertion groove 131a, an anchoring screw 154, which serves as anti-release means, is inserted into the through-hole 131c formed at the one side of the insertion groove 131a.
Here, the tip end of the anchoring screw 154 inserted into the through-hole 131c is inserted into the elongated groove 151a formed on the elongated leg 151, wherein the length of the elongated groove 151a is determined to correspond to the insertion and release distance of the anchoring leg 152 in relation to the insertion groove 131a.
Meanwhile, the locking device 150′ located at the bottom side of the case sections 130a and 130b is implemented by a locking device which can be locked or released by a separate key, so that a manager possessing the key can unlock or lock the case sections 130a and 130b. Because such a locking device 150′ is well known in the art, a detailed description thereof will be omitted.
Now, the action of the rotary sign board of the present invention configured as described above will be described.
Referring to
In addition, the top frame body 111 is anchored to the post W when the rear end of the support arms 114 are anchored to the top frame body 111 while the front ends of the support arms 114 are supported on the outer peripheral surface of the post W, like the bottom frame body 112. The top frame body 111 is spaced apart from the bottom frame body 112, and the space between the top frame body 111 and the bottom frame body 112 is uniformly maintained by the tie bar 113 anchored to the top frame body 111 and the bottom frame body 112.
The display assembly 120 is rotatably installed between the top and bottom frame bodies 111 and 112 inside of the transparent windows 132 of the case sections 130a and 130b.
The display assembly 120 is assembled in the following manner. A plurality of rotatable rollers 111a and 112a are provided on the top and bottom frame bodies 111 and 112. The top rail 121 is located above the rollers 111a provided on the top frame body 111, and the bottom rail 122 is located below the rollers 112a provided on the bottom frame body 112, wherein the cylindrical support plate 123 formed from polycarbonate is anchored between the top and bottom frame bodies 111 and 112.
In addition, the horizontal anchoring bars 125, each of which are formed with the horizontal film insertion slit 125a, are oppositely fixed to the top and bottom frame bodies 111 and 112, respectively. Therefore, the top and bottom edges of an advertisement film 126 with advertisement information are inserted into the film insertion slits 125a of the top and bottom horizontal anchoring bars 125, and the rear side of the advertisement film 126 is supported by the support plate 126.
In addition, each of the vertical anchoring bars 124, which are provided between the top and bottom rails 121 and 122 to be spaced apart from each other so as to allow a plurality of split advertisement films 126, is provided with vertical film insertion slits 124a at the opposite longitudinal edges thereof.
Therefore, the split advertisement films 126, the top and bottom edges of which have been inserted into the horizontal film insertion slits 125a of the top and bottom horizontal bars 125, are arranged to be in close contact with the support plate 123 by inserting the opposite lateral edges of the film 125 into the vertical film insertion slits 124a of the vertical anchoring bars 124.
To the contrary, when removing the split advertisement films 126, the advertisement films 126 can be easily removed from the film insertion slits 124a of the vertical anchoring bars 126 by rotating the anchoring screws 127 in the direction of releasing the anchoring screws 127 so that the anchoring of the advertisement films 126 is released, and then by pulling the advertisement films 126.

In this state, a connection pin 144 is inserted through the pin bores 141a, 142a and 143a formed in the first hinge plate 141, the second hinge plate 142, and the anchoring bracket 143.
Meanwhile, the pin bores 141a, 142a and 143a are inserted into the hinge insertion grooves 131d, which are formed at the top and bottom ends of one pair of adjacent lateral edges of the rectangular frames 131 of the case sections 130a and 130b, respectively. As a result, the interface E between the case sections is positioned at the rotational center of the hinge assembly, whereby no gap is produced in the interface between the case sections 130a and 130b when the case sections are opened or closed.
In the assembly as described above, the first hinge plates 141 and the second hinge plates 142, which are anchored to the pair of the split case sections 130a and 130b, respectively, are connected with the brackets 143, which are anchored to the bottom frame body 112 and the top frame body 111, respectively, through the connection pins 144. As a result, the split case sections 130a and 130b can be pivoted about the connection pins 144, thereby being opened or closed.
Referring to
At this time, because the anchoring leg 152 is shorter than the elongated leg 151, the elongated leg 151 remains in the insertion groove 131a, even if the anchoring leg 152 is removed from the anchoring groove 131b so as to release the locking state.
In addition, if it is desired to release the locking state, it is possible to pull the locking device 150 upward by using the ring-like handle 153 provided at the top of the locking device. Therefore, the locking state can be easily released.
Furthermore, if an anchoring screw 154, which serves as an anti-release means, is inserted into the through-hole 131c formed through a side of the insertion groove 131a, the tip end of the anchoring screw 154 is engaged in the elongated groove provided on a side of the elongated leg 151. The elongated leg 151 is prevented from being released from the insertion groove 131a.
Meanwhile, the locking device 150′ provided at the bottom part is locked or released by a separate key, wherein a locking device locked or released by a key can be employed for the locking device 150′. Therefore, because such a locking device is well known in the art, a detailed description thereof will be omitted.
As described above, in the rotary sign board of the present invention, the case is split into two or more case sections surrounding the display assembly, wherein the split case sections are capable of being pivoted through the hinge assemblies, thereby being opened or closed. As a result, the advertisement object positioned within the rotary sign board can be easily replaced.
In the of the present invention rotary sign board, the edges of an advertisement film are inserted into the vertical anchoring bars and horizontal anchoring bars, and then the film is compressed and anchored by inserting the anchoring screws through the vertical anchoring bars. As a result, the advertisement film can be simply and conveniently installed or removed.
In addition, the vertical bars are arranged at a predetermined interval so that advertisement films can be fitted between the vertical anchoring bars, respectively. As a result, one or more selected advertisement films can be replaced.
In addition, the rotary sign board of the present invention is formed with hinge grooves at the top and bottom ends of the adjacent edges of the case sections at the side where the hinge assemblies are installed. As a result, it is possible to prevent a gap from being produced in the interface between the adjacent case sections when the case sections are opened or closed.
In the rotary sign board of the present invention, the locking device for limiting the opening of the case sections is prevented from being inadvertently released. As a result, it is possible to prevent the loss of the locking device.
In the rotary sign board of the present invention, the frame anchored to the outer peripheral surface of a post is supported on a post through the support arms, each of which has tip ends covered by rubber members. As a result, the frame can be elastically anchored.
