Description

[Detailed description of the invention] This invention provides an advertising device for implementing advertising means simply and in as small a space as possible, so that a number of advertising boards with different advertising surfaces are displayed in a flat manner, sequentially and simultaneously on both the front and back sides, for example in the approximate center of a vehicle such as a train or bus, or in a place where people gather, or in other appropriate locations, i.e., so that all of the advertising surfaces of the multiple advertising boards are displayed in sequence to people on both sides of the surface on which the advertising boards are displayed.

Below, as an embodiment of this invention, a case where an advertising plate is composed of four sheets will be explained with reference to the drawings.

First, the external appearance of the advertising device is as shown in FIG. , L4 protrudes outward. As shown in Fig. 1, these holding frames hold each advertising plate A, B, C, and D at the central bending portions F1, F2, F3, and F4 (in advertising plate A shown in Fig. 2, Then, as shown in Figure 2, the corresponding back sides of these half-folded advertising plates are overlapped, and the upper edges of the half-folded overlapping advertising plates are held at A, S, Ki, and Yu. ing.

Next, in FIG. 3, to explain the relationship between the interlocking mechanism and other parts housed inside the casing N and the holding frame, there is a central axis S in the center, which is connected via steel balls U... A cylindrical drive shaft R is rotated around a central axis S by a motor M. Note that the rotation of this motor M is configured to be decelerated as necessary. Four arms are provided radially protruding from the drive shaft R with a central angle of 90 degrees, and a pin receiver Q1 is installed at the tip of each arm.
Q2, Q3, and Q4 are provided. On the other hand, four F-shaped links K1, K2, K3, and K4 are provided, and pins P1, P2,
P3 and P4 are each rotatably fitted into the receiving holes of the pin receiver. Further, cam rollers X1 and X are provided at both ends of each F-shaped link, respectively.
2, X3, X4 and Y1, Y2, Y3, Y4 are rotatably attached, and a group of cam rollers X1,
..., X4 roll within the gourd-shaped grooved cam E, and the other groups of cam rollers Y1, ..., Y4 are
It is adapted to roll on the outer periphery of a plate cam G having a shape such that triangular protrusions Z and W are formed on the diametrical outer periphery of a disc so as to protrude in diagonally opposite directions. In addition,
The gourd-shaped grooved cam E and the plate cam G are fixed concentrically with the central axis S, and the four F-shaped links K1,...,K4 are installed in such a way that the top with the protruding pin is in either direction. Further, the position of the cam rollers relative to the pins is changed so that the cam rollers X1, X2 are at the top in the right links K1, K2, while the cam rollers X1, Cam roller X in K4
3. It is arranged so that X4 is at the bottom. In addition,
The roots of each of the holding frames L1, . . . , L4 are fixed to the tops of the V-shaped links K1, .

Since this invention is constructed as described above, the interlocking mechanism operates as follows. When the drive shaft R rotates clockwise due to the rotation of the motor M,
Pins P fitted into pin receivers Q1,...,Q4
1, ..., P4 each rotate around the central axis S. That is, pin P1 is at the position of P4, pin P4 is
is rotated toward position P3, pin P3 is rotated toward position P2, and pin P2 is rotated toward position P1.

Next, the holding frames L1, . . . , L4 change their postures as shown in FIG. That is, while the pin P2 moves to the position P1 (the same applies while the pin P4 moves to the position P3), the groove cam E and the plate cam G prevent the F-shaped link K2 from significantly changing its posture. The link K2 remains almost unchanged, and only its position is changed to the position of K1. That is, link K2
The holding frame L2 fixed to the holding frame L2 advances without changing its inclination and reaches the position L1 while maintaining its initial posture. Therefore, the half-folded polymerized advertising plate held by the holding frame L2 also moves forward and reaches the position A. This forward movement is represented by the arrow C in FIG. 1A. Incidentally, at the same time as this operation, the half-folded polymerized advertising plate Y on the left side of the figure similarly reaches the position. This forward movement is represented by the arrow □ in Figure 1A. On the other hand, while pin P1 moves to position P4 (the same applies while pin P3 moves to position P2),
The cam roller Y1 is the same as the plate cam G.
Therefore, the link K1 hardly changes its position on the cam roller Y1 side, whereas the cam roller X1, which rolls within the groove cam E, It rotates largely along cam E. That is, the link K1 changes to the position of the link K4, and therefore, the holding frame L1 is almost turned in half and reaches the position of L4. In this case, by half-turning the holding frame L1, the half-folded polymerized advertising plate A is approximately
It will rotate 180 degrees and reach Yu's position. This rotation is represented by the arrow N in FIG. Incidentally, at the same time as this operation, the half-folded polymerized advertising plate K rotates and reaches the position of S. This rotation is represented by the arrow L in FIG. 1A.

In this way, each advertising plate A, B, C, and D are folded in the center, and two of the four half-folded advertising plates A, SA, Q, and Y are folded at the center and the corresponding back sides are overlapped and held, and two of them are short-distance. forward movement (arrows C, R, O, WA, T, in Figure 1)
At the same time, the other two pieces rotate about 180 degrees around the central axis S (represented by the arrows N, R, Ka, Yo, So in Figure 1). tsu,
Since the advertising plates A, B, C, and D are displayed in this order on a flat surface in front of the viewer, at the same time, these On the opposite side (back side) of each advertising plate, each advertising plate is sequentially displayed in the order of C, D, A, and B in a planar manner to the viewer on the opposite side.

In the above embodiment, the drive shaft R is rotated continuously, but the drive shaft R is rotated intermittently by a central angle of 90 degrees and stopped for about two minutes, so that the viewer can see the advertising plate. It is also possible to make them fully aware of this. In addition, instead of holding the upper edge of the half-folded overlapping advertising plate with a holding frame and leaving the advertising plate hanging down, the holding frame can also securely hold the edges other than the upper edge of the half-folded overlapping advertising plate. You can also do this.

In this way, according to this invention, a large number of advertising plates can be moved to the front and back sides of the viewer by a simple actuation movement, mainly a rotational movement, which does not take up much space and is a means of ``simple movement in a small space.'' On the other hand, it is possible to provide an advertising device that can sequentially display images on a flat surface and has a high advertising effect.
