The closest analogue adopted as a prototype of the proposed utility model is a replaceable advertising sign 5. The prototype device comprises a carrier strip with images or information messages printed on it, wound from the first roller when winding onto the second roller or in the opposite direction from the second to the first . The field of each informational message is indicated by a frame label, which is read by the frame sensor, which generates a control signal for the drive of the carrier band. End position sensors that read the corresponding marks at the beginning and end of the carrier strip control the direction of rewinding of the carrier strip.

The advantage of the device is the simplicity of replacing one frame of an information message with another and the ability to compactly pack a large amount of information presented.

The disadvantage of the prototype is the limited capabilities of the device due to the demonstration at the current time of only one frame of the image, as well as the vertical arrangement of the rollers, in which to drive the strip through the intermediate guide elements using separate drives for each of the two rollers on which the carrier strip is fixed. In addition, the prototype device has limited capabilities for the overall frame size of the information provided. When using a film material, for example, vinyl film, which has recently been used primarily in large-sized advertising signs due to the high quality and ease of applying images as the basis for the carrier strip, a special device is required to tension the strip with a width of more than one meter, which complicates the construction signboards.

The objective of the utility model is to simplify the construction of large-sized advertising signs, increase the amount of information provided and expand the field of exposure of advertising.

- 2 The essence of the utility model lies in the fact that in a removable advertising signboard, containing its ends fixed on the shafts driven by an electromechanical drive, a supporting strip equipped with end position marks and frame position marks, end position sensors and a frame position sensor connected to the control inputs electromechanical drive, and guide elements for tensioning the carrier strip, shafts are installed horizontally at the bottom of the rectangular frame, guide elements for tensioning the carrier the strips are installed above the shafts at the top of the frame, the openings of the front and rear walls of the frame, to which the front side of the carrier strip is facing, are covered with translucent material, and a light source is installed on the wrong side of the carrier strip opposite the apertures, while an even number of frame fields are located on the carrier strip, which are separated by intermediate fields, the images plotted on the fields of adjacent frames are located with their upper sides to the odd intermediate fields, the lower ones to the even intermediate fields, and labels Frame positioning is plotted on the carrier strip through two frame fields.

In this case, the marks of the positioning of the frames are plotted on each odd intermediate field at a distance l from the edge of the carrier strip, and the labels of the final positions are plotted on the first and last odd intermediate fields at distances bi, and for distances a, b, and b, the condition frames between the wrong side of the carrier strip and the light source, partitions made of light-scattering material are installed.

The essence of the utility model is illustrated by drawings, on which:

FIG. 1 - replaceable advertising sign, front view,

FIG. 2 - replaceable advertising sign, side view,

- 3 According to FIG. 1, 2, a replaceable advertising signboard contains a rectangular frame 1 with two identical glazed openings 2, 3 on the front and rear walls, under which there are two fields 4 of the frames of the carrier strip 5 with images or informational messages applied to them. The carrier strip 5 is fixed at its ends on two horizontal shafts 6, 7 installed at the bottom of the frame 1 with support on its side walls, and laid from the shaft 6 (7) up to the bend by one of the guide elements 8 for tensioning the carrier strip, then horizontally to the second similar element 9 and further down to the second shaft 7 (6). Guide elements 8, 9 are mounted at the top of the frame 1 above the shafts b, 7 and can be made, for example, in the form of two wires stretched between the side walls of the frame 1, or, as shown in FIG. 2, in the form of shafts fixed by axles on the frame, similar to shafts b, 7.

At the bottom of the frame 1, between the shafts b, 7, an electromechanical drive of shafts b, 7 is installed. In the proposed example, the drive contains a reversible DC motor 10 with a worm gear, the gear 11 of which is connected via a chain gear 12 to the drive gears 13, 14, mounted on the axis of the shafts b , 7. There are other possible versions of the electromechanical drive.

Inside the frame 1, a lighting source for the advertising sign is installed, made, for example, in the form of a group of electroluminescent lamps 15, which are mounted one above the other on the side walls of the frame 1. In addition, from the wrong side of the carrier strip 5 opposite the glazed openings 2, 3 of the frame on both sides from the light source, partitions 16, 17 of frosted glass or other light-scattering material are installed.

The carrier strip 5 is a vinyl web onto which advertising information is printed. Images are located on fields of 4 frames (hereinafter referred to as frames), which are separated by intermediate fields 18. Length / intermediate field

- 4 18 is equal to at least the distance between the guide elements 8, 9 with a length X of frame 4 not less than the height of the glazed opening 2 {3) of the frame 1.

For the correct presentation of images on an advertising sign, the number of frames 4 on the carrier strip 5 must be even. The arrangement of images on the example of the carrier strip 5 with six frames 4i, ..., 4b and five intermediate fields ISi, ..., 185 is illustrated in FIG. 3. The upper sides of the images of the first and second adjacent frames 4i, 42 are located at the first intermediate field 18i, the lower sides of the next adjacent frames 42, 4z are facing the second field 182. Further in the same order: the top of each pair of frames in odd fields, the bottom - in even fields.

Labels 19 for positioning frames are plotted on the odd intermediate fields 18i, 183, 185, that is, through two fields of the frames, and are located at a distance a from the edge of the carrier strip 5. On the first and last odd intermediate fields 18i, 185, the start mark 20 and the mark are respectively 21 endings (end position marks) of the carrier strip. Labels 20, 21 are located on the opposite side of the strip 5 relative to the labels 19 of the positioning of the frames. The distances b, b, which determine the location of the marks 20, 21, satisfy the relation b Φ b a. Marks 19-21 are made of an electrically conductive material, for example, a metal foil that is glued to the front of the strip 5 in appropriate places as described above.

The reading marks of the strip 5 of the sensors 22-24 are mounted on the upper crossbar of the frame 1 (see Fig. 1). The frame positioning sensor 22 is mounted on the left side of the crossbar above the mark 19. The start sensor 23 and the end (end position) sensor 24 of the carrier strip are installed on the right side at distances corresponding to the location of the marks 20, 21.

Sensors 22-24 are made, in particular, in the form of high-frequency oscillators with inductors, in the field of which marks 19-21 fall when they pass near sensors 22-24. To form the output signals arriving at the control inputs of the electromechanical drive 10, in the sensors 22-24, amplitude detectors are connected to the outputs of the oscillators. In the General case, the sensors 22-24 can be made differently, for example, in the form of photosensors that respond to the light characteristics of the marks 19-21. In this case, the marks 19-21 must have light characteristics that are different from the light characteristics of the carrier strip 5. For example, the marks 19-21 can be made in the form of holes in the carrier strip 5, illuminated from additional light sources.

The sensors 22, 23 and 24 are connected, respectively, to the input of the delay element 25, the R-input of the RS-flip-flop 26 and the S-input of the RS-flip-flop 26, which form the control inputs of the electromechanical drive. The output of the delay element 25 is connected to the first inputs of the elements AND

27 and 28, the second inputs of which are connected, respectively, to the direct and inverse outputs of the RS-trigger 26. The outputs of the elements And 27 and

28 are connected to the inputs of the output stage 29, to the outputs of which an electric motor 10 is connected. In general, the control of the electromechanical drive can be constructed according to other schemes that ensure the stop of the strip 5 for a given time when each mark 19 passes near the sensor 22 and the strip 5 when triggered sensors 23, 24.

The device operates as follows.

In the initial state, frames 4i, 42 are opposite the openings 2, 3 and illuminated by lamps 15. When the electromechanical drive is switched on, the delay element 25 generates a zero level signal for a predetermined time, which determines the exposure time of one pair of frames. The delay time, and therefore the exposure time of each pair of frames, can be fixed, and can vary for all pairs of frames, and for each pair separately. At the same time, at the direct output of the RS flip-flop 26, the signal corresponds to logical level 1, and at the inverse, to logical zero. Zero

- b the levels correspond to the signals at the outputs of the elements And 27, 28, as well as at the outputs of the output stage 29. The electric motor 10 at this time does not work. After the appearance of a signal of the corresponding level at the output of the delay element 25, at the output of the AND element 27, a signal appears corresponding to the logic level 1, and a high level signal appears at the first output of the stage 29, the engine 10 starts to rotate by moving the strip 5 using the corresponding nodes. until the next mark 19 is near the sensor 22. At this moment, the sensor 22 is triggered, the element 25 produces a delay signal corresponding to the exposure time of the next pair of frames 4z and 44, in whose motor does not work. After the formation of the delay time by the element 25, the engine 10 moves the strip 5 to the next pair of frames. These processes of moving and exhibiting pairs of frames will be repeated until the label 21 is near the sensor 24, after which the signal corresponding to the level of a logical unit appears on the inverted output of the RS-flip-flop 26, and to the logical one on the direct one. In this case, after exposing the last pair of frames, strip 5 will rewind in the opposite direction, exposing each new pair of frames in the reverse sequence. When the beginning of strip 5 is reached, the sensors 22, 23 are activated, and all the exposure processes of the pairs of frames are repeated from the beginning.

Ease of execution and rational placement of the main functional units of the proposed design determine its advantages over the prototype.

The horizontal arrangement of the drive shafts b, 7 and the two guide shafts 8, 9 installed above them prevents twisting of the strip edges and wrinkles even with significant field sizes of the demonstration frame. The selected location is rational and in terms of drive design. Tests of the prototype of the advertising sign showed that when pulling a strip with a width of 1000-1200 mm and a frame length of 600-800 mm, to drive shafts with a diameter of 40-60 mm, one electric motor with a power of 30-50 W / h is enough.

Simple and cost-effective means achieve high contrast and uniform illumination of images. Moreover, the use of light-scattering partitions eliminates the possibility of shading the image on one side of the sign opposite the image.

The large size of the demonstration field, the display of images from two sides and the periodic change of frames expand the field of influence of the advertising sign, make it more visible and guarantee familiarization with the information provided.

The combination of simplicity of design and low operating costs with the ability to present a large amount of information can significantly reduce the costs of the advertiser.

The industrial applicability of the utility model is determined by the popularity and accessibility of materials and components used for the manufacture of an advertising sign. For the manufacture of drive and guide shafts, tubes of light aluminum alloys are used, and for the frame, profiled trims are used. Parts are assembled and components are installed using standard fasteners and do not require special equipment.
