Description

[Detailed Description of the Invention] [Technical Field] "Kibari" relates to a billboard that is installed on the rooftop of a pill store and serves as an advertising medium.

[Background technology]

In general, it is more effective to place advertising towers with large advertising areas at high places, but on the other hand, it is difficult to maintain the required wind resistance. There were problems in that the installation cost was high and the installation was troublesome.

[Purpose of the invention]

The present invention has been made in view of the above points, and its purpose is to provide a billboard that does not require much wind resistance and can be installed inexpensively and easily.

[Disclosure of the invention]

(Example 1) Figures 1 to 5 show an example of the present invention.
) is an advertising tower frame constituting the support means, and is formed by a U-shaped support (3) made of copper material and a truss (4), and in this embodiment, the horizontal η1 is triangular. There is.

Around the bottom of the ℃-ta (7), a reducer with a built-in clutch (
8), a winding shaft (9), and other mechanical parts are arranged inside the box (10). This winding shaft (9) is arranged parallel to each outer surface of the billboard frame t1+, and the winding shafts (9) are connected to each other by means of tooth east rows (b).
) The advertising face piece (2) that can be slid up and down on the rail body (5) of The lower end is fixed to the winding shaft (9) so that it can be wound up by the drive of the seventh gear (7), and one end of the tie 17 is fixed to the upper end of both sides of the wire 02.

) is a guide D for the advertising facepiece (2). The figure shows a metal plate I, which is usually used in scissetters, etc., and is a metal plate made by connecting horizontally long metal pieces so that the advertising facepiece (2) will not be exposed to wind. Of course, even if it is a cloth screen, the storage means for the advertising faceplate (2) is a gear train (river) that connects the respective winding shafts (9) of the three advertising facepieces (2) to form a single seven-way All the winding shafts (9) can be driven by the motor (7), but each winding shaft (
In this case, any one of the three advertising face pieces (2) can be placed on the advertising face or rolled up. Also, instead of moving up due to the weight of the cone (+4), the cone α
The shaft may be used as a balance weight to drive both the vertical movement and the vertical movement using the motor (7).

Figures 4 and 5 show the control section of the storage means for the above-mentioned advertising facepiece (2). windmill (20
a) and a generator (20b) connected to a windmill (20a), which outputs a voltage proportional to the wind speed.

In the figure, (D+) is a rectifier diode, (C1) is a smoothing capacitor, and (R1) to (R4) are resistors. 12!11
(c) is an allowable wind speed setting means that can freely set an allowable wind speed according to the advertising facepiece (2), and (c) is a means for storing the advertising facepiece (2) by determining whether the detected wind speed is greater than or equal to the permissible wind speed. The discrimination control means is a wind speed detection means (comparing the output voltage Vo of 2Q with a reference voltage VS, and operating the storage means (c) of the advertising face plate (2) when the output voltage Vo of 2Q is equal to or higher than the reference voltage). Allowable wind speed setting means (21) formed by a voltage comparator (CO) to output a signal VM
generates the reference voltage VS of the comparator (CO)ii
This variable voltage source (VR) is formed by an f variable voltage source (VR).
VR) can be easily realized using, for example, a constant voltage power supply circuit and a tension meter.

Now, when the wind speed increases and the wind turbine (20a) rotates at high speed, the output voltage 0 of the wind speed detection means Q becomes high, and when the output voltage Vo exceeds the reference voltage Vs, that is, the wind speed reaches the preset tolerance. When the wind speed reaches 10 m or 15 m, the operation signal VM of the storing means (4) of the advertising face plate (2) is outputted from the discrimination control means (2), and the storage means (7) is driven to remove the advertising face plate. (2) is the winding shaft (9)
is automatically wound up and stored. Therefore, the wind resistance strength above the allowable wind speed only needs to be considered when the advertising facepiece (2) is stored, that is, the advertising tower frame il+, and the area that receives the wind is determined by the area when the advertising facepiece (2) is placed on the advertising surface. The area is much smaller, and the structure for ensuring wind resistance is much simpler, lowering the installation cost and making it easier to install. Also,
The allowable wind speed can be set freely on the advertising surface (2) using the allowable wind speed setting means υ, and the allowable wind speed is changed depending on whether or not the advertising area (2) has ventilation or the size of the receiving area. This is convenient when replacing the advertising facepiece (2).

(Example 2) Figure 6 shows another example, in which the wind speed detection means (c)
An A/D converter (A) is installed in the wind speed detecting means and a data setting switch (S+
) (S2) Compare the permissible wind speed data set by the permissible wind speed setting means 1 consisting of ... with the permissible wind speed data set by the permissible wind speed data by the determination control means 122 comprising a data comparison circuit, and store when the wind speed data is larger than the permissible wind speed data. The actuation signal VM of means A is output.

(Example Embodiment) Figure R shows still another embodiment, in which a heated resistance wire (20c) is placed on the top of the billboard frame (1), and the resistance wire (20c) The wind speed is detected by taking advantage of the fact that the amount of heat dissipated by the wind changes and the resistance value I of the resistance line (20c) changes. Commercial power (AC) is applied to the series circuit with the resistor (R5), and the load resistor (R5)
An AC voltage proportional to the wind speed is obtained at both ends of the AC voltage, and this AC voltage is rectified and smoothed by a diode (D+) and a wind sensor (C1), and a voltage 0 is output. It goes without saying that the temperature of the resistance wire (20c) may be directly or indirectly detected using a thermistor and a voltage proportional to the temperature, that is, the wind speed may be output.

(Embodiment 4) FIG. 8 shows still another embodiment, in which the billboard frame il
The horizontal cross section of l is square, and a sheet-like material like a cloth is used as the advertising facepiece (2) (Example 5) Figures 9 and 10 show still another example. in,
The upper and lower tower bodies (
la) (lb), and is vertically expandable and retractable.If the take-up pulley (J) is rotated with a ℃-taper (not shown) and the tie t'011 is wound up. , upper tower body (
1a) rises, and at the highest position, the locking means (3 forces) work, and the billboard frame (1) stops in an extended state.On the other hand, when the locking means is removed, the lower tower body (1a) descends under its own weight. In this example, the advertising face piece (2) is rolled up at the first allowable wind speed (for example, 10 m) in the same manner as in the previous example. When the wind speed becomes stronger and reaches a second permissible wind speed (for example, 20 m), the locking means (32) is removed and the first tower body (1a) is stored in the lower tower body (1b). This also reduces the wind-catching area of the billboard frame (1).Therefore, it is easy to ensure wind resistance during strong winds such as typhoons.

(Example 6) Fig. 11 shows still another example, in which the advertising facepiece (
The supporting means of 2) is placed at the bottom of the advertising support column (1)', and a foldable sheet-like advertising face piece (2) is arranged to fit and surround the advertising support post (11').
The upper frame (33a) of 2) is suspended and supported by a hanging rope H that can be freely wound and let out from the advertising support column fl+, and the operation number vM of the storage means (23) is determined from the discrimination control means -. When it is output, the hanging rope (goods) is drawn out and the advertising face piece (2) is folded up and down and stored below. In the figure, the trowel is an illumination lamp, (G) is a lightning arrester, and 1371 is 0-- for fixing the lower frame part (33b).

〔Effect of the invention〕

As mentioned above, Kokuhatsu 1119J is designed to be rolled up or folded for storage.The advertising faceplate is arranged so that it can slide up and down along supporting means such as billboard frames and advertising pillars, and the advertising facepiece can be folded or folded as needed. wind speed detection means for detecting ivy wind speed in a billboard comprising storage means for winding up or folding and storing; permissible wind speed setting means for freely setting a permissible wind speed according to the advertising surface; and a determination control means for determining whether the wind speed is above the permissible wind speed and controlling the storage means, and when the wind speed exceeds the permissible wind speed, the advertising face piece is automatically stowed to reduce the area exposed to the wind. Therefore, it is only necessary to consider the wind resistance of the billboard frame, which simplifies the structure to ensure the specified wind resistance, lowers installation costs, and facilitates installation. In addition, the allowable wind speed can be set freely depending on the advertising facepiece, so when replacing the advertising facepiece with one that has different ventilation and airflow area, all you need to do is change the set value of the allowable wind speed, and the replacement of the advertising facepiece is easy. It has the effect of making it easier to
