Description

FIELD OF THE INVENTION

The invention relates to the field of advertising, namely, to designs of demonstration devices having the ability to periodically change information and intended primarily for use as outdoor furniture.

State of the art

A device for variable presentation of advertising information (see patent for invention GB 1387865, IPC: G09F 11/02, G09F 15/00, publ. 1975.03.19), containing several, from two to five, demonstration blocks made in the form of hollow cylinders placed around the support rack and mounted on it with the possibility of rotation around its own axis.

The disadvantages of the known device include the fact that the portion of the cylindrical surface visible from a particular point at a particular moment in time with advertising information is too limited, which leads to the need for constant rotation of the block or to the placement of fine information on them. The increase in the cylindrical surface of the blocks with such their placement will lead to a multiple increase in the dimensions of the device.

Known advertising and information stand, which allows you to display large advertising images, such as posters or posters (patent RU 34028 U1, IPC: G09F 15/00, publ. 11/20/2003). Similar features with the claimed solution are: the presence of a supporting frame with a base and a roof connected by support legs, and the presence of a demonstration block of a cylindrical shape. The latter is formed by three rounded transparent panels that carry advertising information. A disadvantage of the known solution is the static nature of the demonstration unit, which limits the demonstration capabilities of the installation and makes it impossible to review all the information placed on it from one point.

Known advertising and information stand, in which the demonstration unit is mounted with the possibility of rotation around its axis, which allows you to demonstrate advertising materials 360 ° (patent RU 68164 U1, IPC: G09F 15/00, op. 10.11.2007).

The number of demonstration surfaces carrying advertising images is determined by the shape of the block, which is usually performed in the form of a prism with three, four or more faces (see patents: US 2075245 from 07.27.1936, US 7913436 from 03.29.2011, CN 1453754 from 11/05/2003 , SU 884688 dated 11.30.81). However, an increase in the number of faces is always accompanied by a decrease in the useful area of the demonstration surfaces, and an increase in the latter will lead to a significant increase in the dimensions of the device.

The known solutions of dynamic advertising installations in which each side of the prism is formed by elements with two or more demonstration surfaces, i.e. It is a separate demonstration unit with the ability to change advertising information. One of such advertising and demonstration devices is adopted as the closest analogue for the claimed technical solution (see patent for invention RU 2372669, IPC: G09F 11/02, G09F 15/00, published 10.11.2009).

The features similar to the claimed technical solution are the following: the presence of a frame, the base and upper part of which are interconnected by means of vertical struts, the presence of a device with a demonstration unit rotatable relative to the central axis of the installation, connected with its rotation drive, and the presence of a rotation mechanism of the demonstration units , which provides a periodic change of advertising information.

The disadvantages of the mentioned solutions include the implementation of the demonstration surfaces of the blocks of several arranged in a row of elements carrying fragments of the image. Such a solution allows, without increasing the dimensions of the device, to increase the number of displayed images, of which there are six in the mentioned patent. However, this greatly complicates the design of the rotary device and its drive, which increases the complexity of manufacturing and installation, reduces the reliability and significantly complicates the preparation of advertising images and their replacement.

Disclosure of invention

The task to which the claimed invention is directed is to simplify the device while maintaining its compactness and the ability to simultaneously display several large advertising images that replace each other sequentially on each side of the advertising installation.

One technical result achieved by using the claimed invention is the creation of a simple and reliable design, characterized by low labor input, ease of installation and maintenance.

Another positive result was the expansion of the arsenal of dynamic advertising stands allowing to demonstrate simultaneously several large advertising images that replace each other.

Another positive result is the increase in the area of the demonstration surfaces while maintaining the high compactness of the device.

The problem is solved, and the technical results are achieved thanks to improvements in a dynamic advertising installation comprising a frame, the base and the upper part of which are connected by vertical racks, a rotary device mounted in the frame relative to the central axis of the installation, with demonstration units associated with its rotation drive, and the rotation mechanism of the demonstration blocks.

Improvements to the dynamic advertising installation, according to the claimed invention, are as follows:

- the rotary device consists of two demonstration blocks;

- each block includes a pivoting circle with a vertical axis of rotation passing through its center, onto which two demonstration surfaces are fixed, bent along an arc of a circle of the said circle and placed with the formation of a cylindrical volume and vertical diametrically opposite openings between them;

- the blocks are installed in the opposite direction, with the location of the support-rotary circle of one block at the base of the frame, and the support-rotary circle of the other block - at the top of the frame, and are displaced relative to the central axis of the installation in diametrically opposite sides, at this their vertical axis of rotation is also shifted in diametrically opposite sides relative to the Central axis of the installation at a distance that ensures the placement of one of the demonstration surfaces of each of the blocks in the inside of the cylindrical volume of another block;

- the rotation mechanism of the demonstration blocks is configured to separately rotate the support wheels 180 °, providing a change of the demonstration surfaces located inside and outside the cylindrical volume, with the passage of the demonstration surfaces of the rotatable block through the vertical openings of the second block.

Unlike the prototype, the claimed device has only two demonstration units and they have a fundamentally different design.

Each demonstration unit is made in the form of a glass, the bottom of which is a slewing circle, and a side surface having two vertical cut-outs is formed by two demonstration surfaces. Demonstration surfaces are bent along an arc of a circle of this circle, i.e. along an arc of a circle centered on the axis of rotation of the circle, and placed with the formation of a cylindrical volume between them and with the formation between their vertical edges of vertical openings.

By "demonstration surface" is meant a thin-walled element (plate, panel) that carries advertising information, for example a poster or a poster, which is placed on the convex sides of the demonstration surfaces facing in opposite directions.

When assembling the rotary device, the demonstration blocks-cups are installed in the opposite direction and with partial entry of one into the other so that one block is hidden in the other and extends beyond it only with one of its demo surfaces bearing an advertising image, while the second demo surface of each of blocks hidden inside the cylindrical volume of another block.

The open visible demonstration surfaces of the blocks are turned in opposite directions and are located in the opening of the windows formed between the racks of the frame, which allows the simultaneous demonstration of two advertising images on two sides of the advertising installation. Change of images is carried out by rotating the entire rotary device 180 ° and by rotating each block 180 °. As a result, the installation provides the opportunity to display 4 advertising images in turn on each side.

The area of one advertising image occupies almost half of the cylindrical surface of the advertising installation, the volume of which only slightly exceeds the volume of one demonstration unit, of which there are two in the installation. Such a high compactness of the installation is ensured by the installation of blocks with partial entry into each other.

Compared with a conventional, rotating pillar carrying four, as in the claimed solution, advertising images, the area of the demonstration surfaces is doubled without increasing the dimensions of the device.

The ability to rotate blocks along intersecting paths is ensured by a combination of features: the presence of diametrically opposite vertical openings of the appropriate width, determined by the specific dimensions of the installation and its blocks, as well as the installation of blocks with the placement of slewing rings on top and at the base of the frame and the possibility of alternately separate rotation of the circles, which is ensured by the implementation of the mechanism of their rotation. In fact, the demonstration blocks are made with separate rotation drives, upper and lower, respectively, which can each be connected to its own engine or to the general engine of the installation.

Slewing rings located outside the free edge of the demonstration surfaces of another unit do not interfere with the rotation.

The rotation of the circles, and hence the blocks 180 °, can be combined with the rotation of the entire rotary device or carried out sequentially with it, which is determined by the drive used.

The analysis of the prior art by the applicant did not reveal solutions characterized by the signs that coincide with the distinctive features of the proposed solution, taken together or separately, which allows us to conclude that the claimed technical solution meets the requirements of "novelty" and "inventive step".

The proposed design of advertising media and the principle of changing advertising images are new and unknown from the prior art, which allows us to talk about expanding the arsenal of dynamic advertising settings.

The drive part of the installation can be implemented by any known methods while ensuring the above conditions for the alternate rotation of the blocks.

In the specific case of the installation, the drive of the rotary device includes a drive crankshaft connected to the gear motor located on the central axis of the installation and made with two oppositely directed elbows, one of which is located at the top and the other at the bottom of the shaft. The pivoting circles of the blocks are mounted by bearings on the necks of the upper and lower knees, respectively, which are passed through the center hole of the circle.

The rotation mechanism of the demonstration blocks is made in the form of two identical cam mechanisms, each of which includes a flat cam fixedly mounted, respectively, on the base or upper part of the frame. The neck of the corresponding elbow is passed through the hole of the cam, and the profiled surface of the hole interacts with the pusher rollers mounted on the outer, relative to the cylindrical volume, side of the corresponding slewing ring, at the same distance from the axis of its rotation.

Four pushers are fixed on each supporting turntable. Moreover, to enable rotation, the cam hole profile is made on one side with two recesses separated by a protrusion into the hole, and the distance between the recesses corresponds to the distance between two adjacent pushers.

Due to the fact that the upper and lower cams are made identically and are installed equally on the upper and lower crossbars of the frame, and the axis of rotation of the slewing rings of the blocks are displaced diametrically opposite to the axis of rotation of the device, the central axis of the advertising installation, due to the fact that the elbows are directed diametrically opposite sides, the rotation of the blocks is carried out alternately: first, one block, and after 180 ° of rotation of the drive shaft - the second block.

With a single rotation of the drive shaft through 180 °, the blocks are swapped, and one of the blocks rotates through 180 °. At the next rotation of the shaft by the next 180 °, the blocks are reversed again, and another block is rotated 180 °. The result is a sequential change of all 4 displayed images on each side of the advertising installation (see example below).

The gear motor is fixed, preferably in the upper part of the frame.

For the possibility of installing and changing the duration of the demonstration of advertising images, a programmable control unit connected to the gear motor is used.

The base and the upper part of the frame are made in the form of ring elements, and the racks connecting them are placed diametrically opposite with the formation of two windows for viewing the displayed images.

Each rack can be formed by a pair of vertical bar elements made with hinges for hinging doors and interconnected by a bracket-shaped wall panel, which, together with the doors and the dome, forms a protective casing around the movable elements of the installation, which provides protection from dust, precipitation, etc.

The implementation of the invention

The dynamic advertising installation (see FIGS. 1, 2) comprises a frame 1, including a base 2 and an upper part 3 made in the form of ring elements interconnected by support posts 4 with the formation of a through opening 5 for mounting a rotary device 6 with two demonstration units 7 and 8 and driven. Between diametrically opposed racks 4 are formed two windows for viewing advertising images.

Each block 7, 8 includes (see FIGS. 3, 4) two arcuate curved demonstration surfaces 9 and 10, fixed with one end face on a slewing ring 11 with the formation of vertical openings 12 and a cylindrical volume 13. Surfaces 9 and 10, carrying advertising information can be formed by bending from a sheet blank. In the realized model of the advertising installation, the surfaces 9 and 10 are made of fiberglass by molding.

The supporting turntable And can be made in the form of a disk, solid or perforated to facilitate the design. In the presented example, the slewing ring 11 is made, for the same purpose, in the form of a lattice structure comprising an annular guide 14, intended for fixing surfaces 9 and 10, and connected to it by means of the rod elements 15 of the plate 16 with a Central hole 17 for setting the axis rotation. On the plate 16, from the side external relative to the cylindrical volume 13, four pushers 18 with rollers are fixed, placed around the hole 17, at the same distance from it.

Blocks 7 and 8 are two identical structures, such as glasses with cutouts of the side surface, which, when assembling the rotary device 6, are set in the opposite direction to each other, with a partial entry of one into the other (see Fig. 5).

The drive of the rotary device (see Fig.6-8) includes a gear motor 19 fixed to the upper part 3 of the frame 1, to which the drive crankshaft 20 is connected with two opposite bends 21 and 22 in the upper and lower parts.

The ability to assemble the device is provided by the implementation of the crankshaft 20 composite. The crankshaft includes three coaxial main journals - axes 23, 24 and 25, the extreme of which 23 and 25 are supported by bearings 26. The upper elbow of the shaft 21 is formed by plates 27 and 28, which form the cheeks of the knee, and the axis 29, which is the neck of the knee 21. On axis 29 through the bearing 30 is mounted a pivot circle 11 of block 7, while the axis 29 is passed through the hole 17 of the circle. The lower elbow 22 is formed by plates 31 and 32 and an axis 33, which is the neck of the elbow, on which the slewing ring 11 'of the block 8 is likewise mounted.

In the upper and lower parts of the frame 1 two identical flat cams 34 and 35 are fixedly fixed with a figured hole 36 through which the neck of the corresponding elbow is passed. In this case, the rollers 37 of the pushers 18 of the support-turning circles are placed inside (in the volume) of the figured hole of the corresponding cam.

The axes 29 and 33, forming the vertical axis of rotation of the turntables 11 and 11 ', and hence the blocks 7 and 8, are offset from the central axis Y of the advertising unit along which the drive shaft 20 is placed, in diametrically opposite sides by the same distance X, which ensures placement one of the demonstration surfaces (9 or 10) of each of the blocks inside the cylindrical volume 13 of the other block (see Fig.9).

After assembly and installation in the frame of the rotary device 6 with a drive, the protective cover of the installation is assembled. For this purpose, curved doors 38 with transparent glazing are hung on the hinges of the struts 4 of the frame, and a dome 39 is mounted on the upper annular element 3 of the frame 1. The space between the core elements of each pair is closed with a wall-shaped wall panel 40, the presence of which increases the rigidity of the supporting frame and allows you to hide from the viewer the process of changing the demonstration surfaces. On the inner surface of the doors 38, light sources can be placed to illuminate advertising images in the dark (not shown in the drawings).

Before the installation starts, advertising information is placed on each demonstration surface 9 and 10 of blocks 7 and 8. For this, an advertising medium, for example, a poster or a poster, is laid on the surface (9, 10), smoothed and wrapped around the edges, securing them with a special clip, for example, U-shaped.

The installation is as follows.

When the drive shaft 20 is rotated, its elbows 21 and 22 (axes 29 and 33) move around the shaft 20. Rotating the shaft 20 by 180 ° changes the direction of the elbows to the opposite, resulting in blocks 7 and 8 being swapped. During the said rotation, the rollers 37 of each of the slewing rings 11 and 11 'are moved along the inner surface of the hole 36 of the corresponding cam (34, 35) made on one side with recesses 41 and 42 separated by a protrusion 43 (see Fig. 10a) .

When one of the rollers 37 'of one of the circles, for example 11, encounters a protrusion 43 of its cam 34, the rotation of the circle 11, and therefore the entire block 7, is stopped. However, the shaft 20 continues to rotate, the roller 37 'presses on the protrusion 43, holding in the recess 41 near it, which causes the rotation of the circle 11 around its own axis 29 in the direction opposite to the rotation of the shaft 20 (see fig.10b-c).

During this rotation, the adjacent roller 37 ″ relative to the aforesaid enters the second cam recess 42 and is held there until the third roller 37 ″ ″ touches the cam flat surface (see Fig. 10e). The change of the demonstration surfaces of block 7 has occurred. Next, the block 7 is rotated together with the continuing rotation of the shaft 20 of the rotary device to the "rest" position (see fig.10d).

In the process of the above-described rotation of the shaft 20 by 180 °, the rollers of the slewing ring 11 'move on a flat surface of the opposite part of the hole 36 of their cam 35, while the block 8 does not rotate.

Thus, with one rotation of the drive shaft 20 through 180 °, the blocks 7 and 8 are interchanged, while the block 7 is rotated 180 °. At the next rotation of the shaft 20 by the next 180 °, the blocks 7 and 8 will again interchange, and already the block 8 will rotate 180 °. This ensures a consistent change of all 4 advertising images on each side of the installation. A possible sequence of changing advertising images is shown in Fig.11.
