Description

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

There are many advertising three-position installations, which differ from each other in drive systems. As one of these installations is the design described in the European application. The installation contains trihedral indicator elements, on the faces of which fragments of an advertising poster are applied. Their axes are fixed on the supporting surface and are located in the same plane. Thus, the faces of the indicator elements facing outward in a static state form a flat surface. The rotation of the faces is carried out by gear transmission. Driven cylindrical gears are mounted on the axes of the indicator elements. To maintain rotation in one direction between the driven wheels spurious gears are placed. An electric drive with gear transmission is located under the support base on the installation case. The static position of the indicator elements during the demonstration of the advertising image is ensured by the fact that part of the teeth of the gear wheels is absent and, thus, idling is carried out, which stops the indicator elements after their synchronous rotation of 120 ° [see application EP 802518, G09F 11/02, 1997].

The main disadvantages of this installation, as well as many other installations using faces of trihedral prisms as an information carrier and differing only in drive design, are: low information content, a large number of gaps in the information field and the difficulty of replacing information fields.

Since the main task of outdoor advertising is to attract attention, the term “attractiveness” of advertising can be used. In this sense, three-position billboards of standard sizes are unattractive, which is aggravated by their prevalence.

A well-known advertising installation that implements the principle of "turning over", including 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 through the gear and the 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 RF patent No. 2053572, G09F 11/06, 1996].

The advantages of installations of this type include their high information content.

The main disadvantages of this installation, as well as a number of other implementing the “flipping” method, are: high structural complexity, high weight, significant energy consumption, defects in the information field and the same reduced attractiveness due to the standard installation form and mainly one-sided demonstration of information fields, the replacement of which , as in the case of three-position installations, time-consuming.

As a prototype, a cylindrical installation was chosen to demonstrate information. The installation contains upper and lower bearing surfaces, interconnected by a frame pivotally mounted on an axis. On the upper surface and lower surfaces, the support nodes of the axes of the trihedral indicator elements are fixed with drives (blocks) made in the form of three-beam pins, the rays of which are oriented relative to each other at an angle of 120 °. Under the lower supporting plane between the drives there are stoppers made in the form of hooks pivotally mounted on racks for fixing. When the electric motor is turned on, the frame begins to rotate with the supporting surfaces located on it and the trihedral indicator elements. When the pin of one of the drives approaches the plate (tightening protrusion) and contact with it, the drive is removed from the stopper and rotates around its axis by 120 °, while turning the trihedral indicator element. The stopper fixes its position. The rotation of the drum continues until the rotation of the next trihedral indicator element. Thus, the rotation of trihedral indicator elements is carried out sequentially during rotation of the installation drum itself [see RF patent No. 2239237, G09F 11/02, 2004 - prototype].

The advantages of the installation include its "attractiveness."

The disadvantages of this installation include the low informativeness inherent to three-position installations, the rather complicated design of the frame and its drive, the ability to operate the entire installation only with small dimensions and low rotation speed, since an increase in size and rotation speed will lead to powerful dynamic effects of the plate on the pins and stopper increased noise and wear on parts. In addition, the complexity and complexity of replacing information fields can be noted.

The aim of the invention is the creation of rotating with the necessary installation speed of any diameter and high information content with a simple design of the frame, frame and drive, reliable in operation and operation, providing reduced noise and ease of replacement of information fields.

This goal is achieved by the fact that in a multi-position rotary installation for demonstrating informational materials, consisting of a frame, a drive, a rotating frame, a tightening protrusion, blocks and stops, according to the invention, the frame consists of supporting elements with a fixed platform on which a central axis, an arm with with a twisting ledge and support rollers, one of which is connected to the drive and is leading for the upper platform, on which C-shaped block brackets are fixed in a circle through the console , on the central shaft of each of which there is a flywheel for contact with a twisting protrusion and drive levers with elastic elements for turning horizontal strips with grooves through the vertical driven fingers, the radii of curvature of which are equal to the radii of the antifriction rings, the center of which coincides with the axis of the central shaft of the block and which are attached to C-shaped brackets on their horizontal platforms, the shape of which and the bevels on the edges are designed to enter and exit the vertical driven fingers of the horizontal strips and elastic elements of the drive levers, which are designed to interact with cylindrical stoppers held in extreme positions by elastic elements and stops and having a groove for the horizontal driven fingers of horizontal strips to pass, in which there are threaded holes with threaded clamps for fastening vertical strips with attached to them information elements.

Preferably, the twist protrusion is located on the rod of the electromagnet.

The invention will now be explained in more detail with reference to the accompanying drawings.

In Fig.1 (information elements are not conventionally shown) - section along aa in Fig.5; figure 2 is a section along BB in figure 5; figure 3 is a section along bb in figure 5; figure 4 is a cross-section along G-G in figure 2; figure 5 - installation, top view; figure 6 is a section along DD in figure 2.

A fixed platform 2 is mounted on the supporting elements 1, on which the supporting rollers 3 are placed, one of which 4 is the leading one and connected with the friction roller 5, which sits on the drive shaft 6 of the entire installation. In the center of the fixed platform 2, a central axis 7 is mounted, a bracket 8 is attached on which an electromagnet 9 is located, on the rod of which a twisting protrusion 10 with a friction block 11 is mounted. The upper platform 12 is supported on the support rollers 3 and the drive roller 4 with an opening for the central axis 7 The consoles 13 are attached to the upper platform in a circle with the C-shaped brackets 14 mounted on them. Each bracket 14 is a supporting frame of the block 15, including a through central shaft 16 passing through the upper 17 and lower 18 of the horizon C-shaped brackets 14. Under the lower horizontal platform 18 on the shaft 16, the lower drive lever 19 with the elastic element 20 and the flywheel 21 are rigidly seated. Above the upper horizontal platform 17 on the central shaft 16, the upper drive lever 22 with the elastic element 23 is rigidly seated. Covers 25 are attached under the upper horizontal platform 17 and above the lower horizontal platform 18 through the bushings 24. Antifriction rings 26 are attached to the upper 17 and lower 18 horizontal platforms, and antifriction rings 27 are attached to the covers 25. Between the rings 26 and 27 horizontal slats 28 are placed on which vertical 29 and horizontal 30 driven fingers are mounted. Through the upper and lower horizontal platforms 17, 18 and the cover 25 pass holes 31 in which are mounted a cylindrical stopper 32 with grooves 33 and stops 34, which are supported by elastic elements 35 attached to the covers 25. In the horizontal bars 28 there are threaded holes with threaded clamps 36, which press against the stops 37 vertical strips 38 with attached information elements 39.

Installation works as follows.

The drive 6 through the friction roller 5 and the drive roller 4 transmits torque to the upper platform 12. Rotating around the central axis 7, the movable upper platform 12 rests on the drive roller 4 and the support rollers 3 and through the console 13 with the C-shaped brackets 14 fixed to them moves blocks 15 in a circular path. In this case, the flywheel 21 alternately comes into contact with the friction block 11. The dimensions and mass of the flywheel 21 are selected in such a way that the power impulse received from the contact is sufficient for the flywheel 21 to make one complete revolution, during which a complete cycle of operation of the block 15 takes place. This cycle consists in the fact that the torque of the flywheel 21 is transmitted through the central shaft 16 to the drive levers 19 and 22, which with their elastic elements 20 and 23 rotate the horizontal bars 28 through 180 ° by the vertical driven fingers 29. At the same time, the drive levers 19 and 22 move the cylindrical stoppers 32 through the holes 31, overcoming the resistance of the elastic elements 35 so that the grooves 33 of the cylindrical stoppers 32 are lowered and the horizontal driven fingers 30 of the horizontal strips 28 are passed. A similar process is carried out by the drive levers 19 and 22 with the stoppers systems located on sections of the completion of the turn. After the drive levers 19 and 22 have passed, the elastic elements 35 return the cylindrical stoppers 32 to their original position and the horizontal driven fingers 30 exclude the movement of the horizontal bars 28. The accuracy of moving the horizontal bars 28 by 180 ° is ensured by the fact that on the upper platforms 17 and on the lower platforms 18 bevels along which the elastic elements 20 and 23 descend from the platforms horizontal 17 and 18, and rise along them, making contact with the vertical driven fingers 29 or leaving it. In this case, the horizontal platforms 17 and 18 play the role of cut-off planes. Having made a complete revolution, the drive levers 19 and 22 stop in a neutral position on platforms 18 and 17. The horizontal bars 28 have a groove whose radius of curvature is equal to the radii of curvature of the antifriction rings 26, and the lower smooth surface of the horizontal bars is in contact with the antifriction rings 27. This ensures accurate the rotation of the horizontal strips 28 around the axis of the block 15 with minimal resistance. The reliability of the fixation is provided by attaching the antifriction rings 26 to the horizontal platforms 17 and 18, and the rings 27 to the covers 25. The vertical bars 38 with the information elements 39 attached to them, pressed against the stops 37 by threaded clips 36, move along with the horizontal bars 28 and unfold in the demonstration plane when the horizontal strips 28 are rotated 180 °, forming with a developed information elements 39 neighboring blocks 15 a single information field. In the next cycle, the next pair of horizontal bars 28 is deployed, and the previous one is folded, pushing between the platforms the whole set of bars with information elements 39. Obviously, the number of positions, i.e. the number of information fields is equal to the number of pairs of horizontal bars 28 in each block 15.

The replacement of information fields is done by turning the clamps 36 holding the vertical slats 38 with the information elements 39 attached to them.

It should be noted that the working cycle of the blocks can occur for each revolution of the installation or in a predetermined mode through the inclusion of the electromagnet 9. In this case, the friction block 11 comes into contact with the flywheel 21 only when the electromagnet 9 is turned on, which can be carried out by a time relay. For example, the change of information fields on the installation can be carried out through 1, 2, 3, etc. revolutions.

Thus, according to the proposed invention, a device of any diameter and high information content, rotating with the speed necessary for effective perception, is created with a simple design of the frame, frame and drive, reliable in operation and operation, providing reduced noise and ease of replacement of information fields.

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.
