Description

The invention relates to the field of advertising and can be used to represent various information successively changing each other in one device.

There is a method of demonstrating images on advertising devices, which consists in moving or rotating a set of information elements containing fragments of a common image that are installed in the same plane, creating an information field. This method is implemented, for example, in an advertising device, where information elements are located on trihedral prisms. When combining fragments in one plane, a single image is created on the entire information field. The change of information is carried out by turning all the prisms around its axis with the help of asterisks mounted on the axes of the prisms, drive and roller chains. An increase in the amount of information is achieved by installing a parallel series of prisms [see A.S. No. 943823, G09F 11/23, 1982].

The disadvantage of this method is the small information capacity, the structural complexity of the devices for its implementation and the imperfection of the surface of the information field due to gaps and incomplete rotation of the prisms and the impossibility of bilateral demonstration of information fields.

A known method of demonstration in advertising devices, which consists in "turning over" information elements mounted on a supporting frame. The method is carried out by rotating the supporting frames 180 ° around the central axis. This method is implemented in a device in which the supporting frames with one end are pivotally mounted on the central axis and fixed with magnets. Each supporting frame is released by the force necessary to detach from the magnetic layer, rotated 180 ° and fixed with a magnet [see Patent No. 2029993, G09F 11/00, 1995].

The disadvantage of this method is that the information elements deployed in this way are separated by a rather large gap and are not in the same plane, and a two-way demonstration is excluded.

A known method of demonstration in advertising devices, according to which each information field consists of two information elements fixed on a supporting frame, each of which has information elements on both sides. The supporting frames are formed in two packages adjacent to each other by the ends. First, the packets are shifted along the ends in opposite directions each by a distance equal to half the thickness of the supporting frame, and then the extreme bearing frames in the packages are simultaneously moved to the vacated space in the adjacent package. After that, the shift of the packets and the movement of the supporting frames are repeated. Thus, a change of information fields is achieved on one and the other sides of the demonstration device. The number of information fields on both sides of the installation is equal to the number of supporting frames in the package [see Patent No. 2163733, G09F 11/00, 1998].

The disadvantage of this method is the significant structural complexity of any device that implements two main features of the method - the formation of the information field of only two information elements and the lateral displacement of packets from the supporting frames exactly half the thickness of the supporting frame. Indeed, with the significant size of the information field, which takes place in real advertising devices, the size of the information elements must also be significant, which imposes a number of requirements on the rigidity of the bearing frames and the speed of their movement when changing images quickly. In addition, when the bearing frames are displaced exactly by half their thickness, the need to ensure this accuracy should be taken into account in the presence of obstacles in the form of wind load and deformation of drive structure details. Otherwise, the ends of the supporting frames and the malfunctions of the device are inevitable.

A device that implements the method described above contains a housing with supporting frames installed in it with information elements, a roller chain meshed with sprockets, and a drive. Two pairs of wedge-shaped cams are mounted on the roller chain. Bearing frames are made up of two packages, installed by the ends to each other. Each supporting frame is equipped with a latch located in the center of its base. The latches of the supporting frames of each package are installed on the opposite sides of the through closed quadrangular groove with the possibility of movement along it. A quadrangular groove is made in the bottom of the housing. The design of the latch and the supporting frames with information elements in the claims, drawings and description is missing [see Patent No. 2163733, G09F 11/00, 1998].

The advantages of the method and device include the absence of a bearing frame beyond the dimensions of the device case, the ability to provide due to this a reduction in the dimensions of the device and a two-way demonstration of information fields.

The disadvantages of this device are the same as the method that it implements. They are exacerbated by the fact that the latches of the supporting frames are placed in the groove of the bottom of the housing. This leads to the fact that the bearing frames work under any external load not only on bending, but also on stability, which makes double demands on the rigidity of the bearing frames and, ultimately, leads to an increase in their weight and complexity of the design. The latches that hold the information elements and move them along the groove must take on all the loads on the supporting frames and provide movement with minimal friction and without wedging. In this case, the clamps should be not only sufficiently structurally complex, but also for this reason, and also because of the necessary strength, sufficiently bulky. In this case, most likely, the lateral size of the clamps can and should be greater than the thickness of the supporting frames, which violates one of the signs of the method that implements this device. Indeed, in this case, the packages of the supporting frames will have to be shifted in the transverse direction not by half the thickness of the supporting frame, as indicated in the method, but by half the thickness of the retainer, which this method does not protect.

It is not by chance that the inventors do not cite either the retainer or the supporting frames in the text of the invention.

It should further be noted that achieving the required accuracy of displacing the packets by half the thickness of the bearing frame in this device is very difficult due to the fact that it depends on a number of factors: cam geometry, chain pitch, ratio of the bearing frame thickness and the distance between the cams, the number of bearing frames in the package, their width, etc. Given the known tendency of the chain to stretch, one can doubt the operability of the proposed design.

Since the device according to this method uses only two information elements for the entire information field, the dimensions of the bearing frames, as well as their weight, as indicated earlier, should be significant. With a double cycle of changing one information field, the supporting frames must move at a very high speed, which, given their mass, will lead to significant dynamic loads and, as a result, to increased noise, energy consumption, swaying, shock and, ultimately, rapid destruction devices.

In other words, such a device can only be used in small stands, in enclosed spaces without wind loads and with very careful design calculations.

However, the main disadvantage of the method and device is the appearance of mixed information fields that do not carry any useful information, and with the same frequency as the appearance of the main information fields.

The closest to the claimed method in technical essence is the method of demonstration in advertising devices, which consists in "turning over" information elements, is also implemented in a device where the information element on the supporting frames is previously released from the stop, rotated 180 ° and placed in the same plane with the following information element, thereby creating a single information field. Then the cycle is repeated [see patent No. 2053572, G09F 11/06, 1996 prototype].

The disadvantages of this method are the impossibility of two-way display in one device and the complexity of replacing the information elements of the individual information fields of the device.

The closest to the claimed technical essence is the method of "turning over", implemented in an advertising device that includes a housing with blocks of information elements fixed on a supporting frame on both sides. The load-bearing frames are spring-loaded and fixed using a locking mechanism, including fork clamps, stoppers, cams, holders and brackets with springs. The rotation of the information elements around the drive axis is carried out by means of a drive through a gear and a gear wheel. When one information element is rotated 180 °, it appears in the same plane with the adjacent information element, forming a single information field [see patent No. 2053572, G09F 11/06, 1996 prototype].

The main disadvantages of this device, which implements the method of "turning over", are the low quality of the information field arising from the gaps between the information elements and their bulge that occurs when you try to "sharpen" the bearing frame, in order to reduce the gaps; high energy intensity - as a result of friction between the brackets holding the supporting frame, the complexity of the design of the supporting frames and drive of the device, low reliability of its operation, the complexity of commissioning and maintenance. This design also does not provide for the possibility of performing the stand bilateral.

The aim of the present invention is to increase the information capacity due to the two-sided display in one device without demonstrating information fields that do not carry useful information, masking them for double movement of information elements or pairing of one-way devices; simplifying the design of the drive and information elements, facilitating and accelerating the process of replacing them, reducing the dimensions of the device, its energy intensity and noise level.

This goal is achieved by the fact that in the way of two-way demonstration of information fields using the device, information fields are divided into information elements attached to the supporting frames and formed into pairs of packets, in the starting position in each packet of each pair are placed the supporting frames with information elements for demonstration with on one side of the device, and in the other package, the supporting frames with information elements for demonstration on the other side of the device, for changing information fields from chum in the package simultaneously from both sides of the plane unfolded carrier framework 180 ° and placed with their approximation until until all bearing frame, except one, a single packet does not pass into the other, after which the movement cycle is repeated in reverse.

The essence of the method is easy to understand according to the scheme (top view) in figure 1.

The entire device is divided vertically into several blocks, and in each block information elements 2 are attached to the supporting frames 1. The width of the information elements 2 is equal to the width of the blocks, and parts of the information elements equal in width to the width of the supporting frame are attached to adjacent bearing frames. The supporting frame 1 is formed in two packages. In the starting position, in one package, the supporting frames 1 with information elements 2 ′ intended for demonstration from the “rear” side of the device are installed, and in the other package, the supporting frames 1 with information elements 2 ′ intended for demonstration from the “front” side of the device . On the extreme load-bearing frames 1a in each block, parts of the “front” information elements are attached on one side and parts of the “back” on the other. The four-sided trajectory 3 determines the movement of the supporting frames, while two opposite sides are straight, and two are semicircles.

The method is as follows.

The supporting frames 1 are moved from one package to another along a four-sided path 3. In this case, the supporting frames 1 with the “front” information elements 2 ′ and the supporting frames 1 with the “rear” information elements 2 ′ ′ are rotated from 180 ° simultaneously from the “front” and the "back" sides of the device. In this case, the bearing frames 1 are in a new package, pushing the bearing frames 1 already there for a distance equal to the thickness of the bearing frame 1. Movement is carried out until the bearing frames 1a are at opposite ends of the packets, pushed by adjacent bearing frames 1. Bearing frames 1a do not rotate. After that, the whole process of moving is carried out in the opposite direction.

The number of supporting frames 1 in the block can be any and this number determines and is equal to the number of information fields on both sides of the device, and the number of supporting frames 1 in the package is equal to the number of information fields to be replaced on one side of the device.

In addition, the goal is achieved due to the fact that, for the implementation of the method, a device for bilateral demonstration of information fields, consisting of a frame, drive and blocks, according to the invention, each block is composed of a pair of packages with bearing frames formed by upper and lower carriages connected by vertical racks to which parts of information elements are attached that are equal in width to the width of the supporting frame, parts of information elements are attached to two adjacent supporting frames on both sides, m to the last, non-rotating, supporting frame in each package are attached parts of information elements belonging to different demonstration sides of the device, while the width of the information element is equal to the width of the block, bevel gears located in the horizontal shaft connected to the drive are installed in meshing with bevel gears mounted in each block on vertical shafts, on which top and bottom two-sided carriers with elastic elements are fixed and which are housed in bearing housings installed in the center of the cutting planes, which are attached at the top and bottom to the frame and to which monorails are four-sided of rectangular cross section, two sides of which are straight and two are semicircles, and on which four sleeves with cylindrical stops placed in them are mounted based on elastic elements attached to monorails, and having spherical heads located at the level of the side ends of the two-sided carriers, and annular grooves located at the level of the shoulders p faces, which are placed on the monorail in groups of three, of which the inner side of the monorail section is covered by one roller, and the outer - two, the ends of the axes of which are at the level of the elastic elements of the two-sided carriers, and the axes of all three rollers are mounted in carriages in which holes in which the presser legs are located and ridges to which the vertical legs are pressed with the presser legs.

Figure 2 shows a General view of the block; figure 3 is a General view of a in figure 2; figure 4 is a section along BB in figure 2; figure 5 is a section along bb in figure 3; in Fig.6 is a section along G-G in Fig.3.

A device for the two-sided demonstration of information fields consists of a frame 4, on which the drive 5 is installed and to which the cutting planes 7 of several identical blocks are installed at the top and bottom on the bent shelves 6. A horizontal shaft 8 passes through the shelves 6 at the top, on which bevel gears 9 are mounted over each of the blocks and which is connected through the coupling to the drive 5. Bevel gears 9 comprise gear pairs with bevel gears 10 mounted in each block on vertical shafts 11 on which top and bottom, respectively, above and below the cutting planes 7, bilateral carriers 12 are mounted with elastic elements 13. Vertical shafts 11 are placed in bearing housings 14 mounted in the center of the cutting plane awns 7 to which monorails 16 are attached at the top and bottom of the uprights 15, in which four sleeves 17 are installed, each of which has cylindrical stoppers 18 having a spherical head 19 and annular grooves 20, and supported by elastic elements 21, also attached to monorails 16, which have a rectangular cross section and are made four-sided so that two opposite sides are straight and two are semicircles. On the monorails 16 there are carriages 22, in which two axles 23 of the outer rollers 24 and one axis 25 of the inner rollers 26 are installed, which have collars located at the level of the grooves 20 of the cylindrical stops 18. In the carriages 22 there is a threaded hole 27 for the presser legs 28 and ridges 29 for uprights 30 with parts of information elements 2 ′ or 2 ″ attached to them. The lower and upper carriages 22, together with the vertical posts 30, pressed to the ridges 29 by the presser legs 28, form a supporting frame 1.

The device operates as follows.

After turning on the device, the drive 5 through the horizontal shaft 8 and bevel gears 9 transmits torque to the bevel gears 10, vertical shafts 11 and, accordingly, to the double-sided carriers 12, the elastic elements 13 of which slide off the cutting planes 7 on two sides and come into contact with the upper ends of the axles 23 of the outer rollers 24 and move the carriage 22 along the monorails 16. In this case, previously the faces of the two-sided carriers 12, facing the cutting planes 7, are pressed on the spherical heads 19, cylindrical Axes 18 descend, overcoming the resistance of elastic elements 21 so that the annular grooves 20 are at the level of internal clamps rollers 26 and rollers 26 is passed through its cross section. After the passage of the two-sided carrier 12, the elastic elements 21 return the cylindrical stoppers 18 into place and the inner rollers 26 of the next carriage abut against the cross-section of the cylindrical stoppers 18. All this happens simultaneously on both sides of the device in all blocks.

Bilateral carriers 12 rotate the carriages 22 180 °, lower the cylindrical stoppers 18 and push the carriages 22 into adjacent packages to the width of the carriage 22, thereby pushing all the packages at the same distance.

This entire cycle is repeated until all the carriages mutually move from one neighboring packet to another, after which the actuator 5 is switched to reverse and the cycle is carried out in the reverse order.

The replacement of the information field is as follows.

The presser legs 28 in all the blocks are rotated counterclockwise, due to which they are threaded up and away from the clamped vertical posts 30. The vertical posts 30 together with the information elements 2 are removed forward, and new information elements 2 with vertical ones are put in their place racks 30, which are clamped by the reverse rotation of the presser legs 28.

Thus, according to the proposed invention, a method has been created that allows to increase the information capacity due to two-sided display in one device without demonstrating information fields that do not carry useful information, masking them by double moving information elements or pairing one-way devices, simplify the design of the drive and information elements, facilitate and speed up the process of replacing them, reduce the dimensions of the device, its energy intensity and noise level.

Although the invention has been described with reference to a specific embodiment, a person skilled in the art will understand that various changes and additions to the claimed design are possible within the scope of the idea of the invention, if they do not go beyond the scope of the attached claims.
