Description

The invention relates to information technology and can be used in advertising devices and training aids.

The purpose of the invention is to expand the field of application of the device by making it possible to operate with a movie effect.

In FIG. 1 shows a device, front view; in FIG. 2 - the device in plan, a) - the flat shield is rotated through an angle of 90 °, b) - by an angle of more than 90 °; in FIG. 3 - flat boards; in FIG. 4-6 - the implementation of the driven and drive gears.

The advertising device contains a stand 1, the base of which consists of flat panels 2, 3, 4, and holes 6 are made in the frame 5.

Shields 2, 3, 4 can be installed vertically, horizontally, the number of which can be different depending on the width of the stand, and fixed on the protrusions 7 located in the holes 6.

The total area of flat panels forms a common screen.

On the lateral ends and lateral surfaces of the flat panels 2, 3 and 4, protrusions 7/8 and 9 are made.

The protrusions 8 and 9 interact with the holes of the belts 10, 11, 12, wound on coils 13 and 14, the shafts of which interact with the holes 6 of the frame 5. And at the ends of the coils 13, 14 are attached gears 15 and 16, interacting with each other.

When the ribbons 10, 11 and 12 are pulled onto the boards 2, 3 and 4 (as shown in Figs. 1 and 2a), they form a common screen on which any advertising object (frame) is drawn or text is written, for example Screen.

The advertised object may be displayed on a separate sheet or printed using a printing method or photographed on a large sheet.

. The sheets are then cut to the size of flat panels and glued to them.

Educational institutions have educational posters on various topics in large quantities on a single topic. All these posters are cut according to the number of flat panels 2, 3, 4 and glued to the tape 10, 11, 12 with a rotation of the flat panels 180 °.

In this way, you can stick cartoons or other documentary, feature films.

VI

You can reel in large format slide tapes previously shot through the lens.

At the ends of the protrusions 7, gears 17, 18, 19 (gears or sprockets) are attached. Their number is equal to the number of flat shields 2, 3, 4, wrapped in a common circuit 20, interacting with them. Below the gear 19 (Fig. 1), a follower gear 21 is mounted on the extension of the protrusion, interacting with a fixing drive gear 22, mounted on the shaft of the electric motor 23, on which the handle 24 is mounted.

To prevent the chain 20 from moving away from centrifugal force, the chain 21 is provided with stop brakes 25 (Fig. 2). When the chain 20 does not rotate: a gap e is formed between it and the brake stops 25 (Fig. 1 - a gap e is shown at the bottom of the chain 20).

In FIG. 4 and 5 show the locking drive gear 22 with two sectors-angles a, where there are no surfaces

a tooth. Gear circumference

part of the sector of the locking drive gear 22 (between angles a) is equal to half the length of the driven gear 2.1.

In FIG. 6, the length st D./2 around the circumference of the drive gear 22 is made at one angle a, where the tooth is missing.

The operation of the device consists in the fact that when the crank 24 is rotated by the motor 23, the locking drive gear 23 begins to rotate, interacting with the driven gear 20 mounted on the protrusion 7 made with a gear 19 (Fig. 2), on which together with the gears 17, 18 put on chain 20, and

interacting with them, rotate clockwise. Due to the fact that on the protrusions 7. interacting with the holes 6, flat shields 2, 3, 4 are fixed, interacting with the holes made in the belts 10, 11, 12 will move them clockwise. In this case, the belts 10,11,12 will be unwound from the reel 14, interacting with gears 15.16, mounted on the shafts of the coils 13,14, and will be wound on the coils 13.

The teeth of the locking drive gear 22 are made through an angle a (Figs. 4, 5, 6), the number of which is equal to the number of teeth made on the half perimeter (g D / 2) of the driven gear 21. As a result, when the flat shields 2,3.4 form the shield (Figs. 1, 2, 5) of the brake stops 25 is pressed by solenoids (not shown) to the circuit 20 and it stops. After turning through an angle a, another part of the teeth of the drive gear 22 starts to cling to the teeth of the driven gear 21, and at the same time, the solenoids retract the stop brakes

from chain 20. After turning through angle a, the engagement of the teeth of gears 22, 21 is repeated. If the frequency of fixation of flat panels 2, 3, 4 occurs, say, sixteen times per second using an electric motor 23,

there is a movie effect.

The rewinding of the tapes 10,11,12 is carried out using an electric motor mounted on the shaft of the coil 13 (not shown in the drawing).

When operating as an advertisement, the latching frequency will be determined depending on the operation of the time relay. The length of the tapes 10,11,12 depends on the number of advertised objects.

Claims (1)

The claims An advertising device comprising a stand, in the frame of which holes are made with a set of information elements in the form of reels for tapes, and a drive, characterized in that, in order to expand the scope of the device due to to ensure its operation with the effect of a movie, the base of the stand is made in the form of a set of flat panels, in the ends and on the side surfaces of which there are protrusions, respectively for installation in the holes of the frame and for interacting with the drive and the holes of the tapes, each of which is located on the corresponding flat shield.
