Description

The invention relates to information and advertising technology - means for the visual presentation of information, namely, dynamic advertising and information stands and demonstration installations made with the possibility of changing the information provided, in which graphic elements of information and / or advertising nature are applied to many rotary demonstration elements.

Various advertising and information boards and stands are known, containing a frame with a screen placed in it, composed of a set of demonstration elements made in the form of rotary trihedral prisms. Prisms are interconnected with the possibility of synchronous rotation [patents for inventions of the Russian Federation No. 2267165, 2092907, utility model patent No. 18790 and others, IPC G09F 11/02].

However, the use of trihedral prisms in these boards and stands provides one-sided reproduction of advertising information on the screen. In crowded places, the advertising information displayed with such a device covers a limited number of potential consumers.

It is also known a device for two-sided demonstration of images, containing two parallel rows of rotary prisms mounted on the media. In this case, the information carrier is made in the form of moving flexible closed loops forming at least two branches, on which 4-sided or 3-sided rotary prisms are fixed, used as moving information fields. The rotation of the prisms is carried out on a curved section of a closed loop. In the device, the axis of the rotary prisms are fixed on closed loops located in parallel planes, while the mechanism of rotation of the prisms is located on a curved section of their movement, and the faces of the prisms are rotatable around its axis, and the device is equipped with internal illumination of images [RF patent No. 2253904, IPC G09F 11/02].

However, in this advertising design, image change takes a long time, i.e. demonstration elements change their image (rotate) sequentially only on a curved section of the trajectory. In addition, this advertising design has significant dimensions.

The closest analogue to the claimed invention is an advertising device for presenting dynamic information containing a screen in a frame from a set of demonstration elements, each of which is a tetrahedral prism equipped with an axis to enable the prisms to rotate. The prisms are placed in two frame holders, one of which is designed for fastening even demonstration elements and is movably mounted on the frame with the ability to move in a direction perpendicular to the screen by means of a movement mechanism, and the second - odd demonstration elements. Each frame holder is equipped with a separate prism turning mechanism, which is a belt drive engine [patent WO 03050789, IPC G09F 11/02; G09F 11/00].

However, the use of two independent rotation mechanisms installed in their frames, and two electric motors leads to a heavier design and the need to synchronize the rotation of the even and odd demonstration elements of the advertising device.

The objective of the invention is to create an easier to manufacture advertising device with reliable synchronous rotation of the demonstration elements.

The technical result of the claimed invention is to simplify the design of an advertising device in which one mechanism is used to synchronously rotate even and odd prisms. In addition, through the use of flat holders in the form of strips placed on the surface of the frame, the useful advertising area of the device has been increased.

The problem is solved in that in an advertising device for presenting dynamic information containing a frame with two holders fixed to it, a screen consisting of a set of demonstration elements, each of which is a tetrahedral prism, equipped with an axis to enable rotation, while one of the holders is designed to fix even demonstration elements and is made with the ability to move in the direction perpendicular to the screen, and the second - odd demonstrators elements, the prism rotation mechanism, made in the form of a transmission mechanism connected to the engine, according to the proposed solution, the second holder is arranged to move in a direction perpendicular to the screen, each holder consists of a pair of upper and lower bars made with the possibility of synchronous movement over a distance, necessary to rotate the even and odd prisms with the subsequent return of the strips to their original position, the transmission mechanism consists of two shafts with pushers for gate the even and odd respectively prisms, prism provided with fixed cams on their axes, arranged to interact with pushers, the engine rotation mechanism is fixed to the frame. For synchronous movement of pairs of strips, the device is equipped with eccentrics located between the upper and lower strips, the ends of which are connected by return springs. Holders, pushers, cams are placed in the cavity of the frame, while the frame is equipped with holes for moving the axes of the demonstration elements. Prisms are made of transparent material and equipped with lighting devices located in the cavity of the prisms. The pusher and the cam are made flat, located in mutually perpendicular planes, the cam is equipped with four toothed protrusions, and the pusher is equipped with two, while the cam and the pusher interact through the interaction of their toothed protrusions. The advertising device is equipped with external lighting devices. Screens are equipped with transparent protective panels. Each face is additionally equipped with fasteners for the advertising media. Each prism is additionally equipped with stiffeners installed in the inner cavity of the prism.

Advertising design contains a rectangular frame 1, which can be made of a profile of a U-shaped cross section. A frame consisting of a set of demonstration elements 2 is mounted in frame 1. Each demonstration element 2 is a tetrahedral prism having a square in cross section and rotatable around its vertical axis. The prisms are equipped with 3 axes (upper and lower), which are connected through bearings to two holders, each of which consists of a pair of upper and lower brackets 4. One pair of brackets is used to fix even demonstration elements, and the second pair of brackets is odd demonstration elements . Pairs of strips 4 are movably fixed on the frame 1 with the possibility of movement in the direction perpendicular to the screen using a movement mechanism that includes an engine connected to the eccentrics 8 located on the sides of the screen. The synchronous rotation of the prisms is provided by the rotation mechanism. Each prism is mounted on mandrels 12 located on the axles 3. A cam 7 is mounted on the axis 3 of each prism on the upper side.

The prism rotation mechanism is made in the form of a transmission mechanism connected to the engine, which includes two shafts 5, one of which is designed to rotate even and the other odd prisms. The shafts 5 are equipped with pushers 6, configured to interact with cams 7 mounted on the axes 3 of the prisms 2. The pushers 6 and cams 7 are made in the form of flat parts and are located in mutually perpendicular planes. The cam 7 is equipped with four gear protrusions, and the pusher 6 - two, while the interaction of the pusher 6 with the cam 7 is carried out by means of their gear protrusions. The engine is connected to the shafts 5 through gears 9, 10 and 11, one of which - an additional gear 10 - provides the opposite direction of rotation of one of the shafts 5. The design of the rotation mechanism allows you to rotate the prisms at a fixed angle of 90 °. Details of the rotation mechanism are located in the cavity of the frame, while the shafts 5 are fixed using brackets 13 provided with bearings.

The movement mechanism includes an engine connected to two shafts 16 mounted on the sides of the frame. On the shafts 16 in the upper and lower parts, an eccentric 8 is fixed, located between the upper and lower bars 4. In this case, the kinematic connection of the shafts 16 with the motor ensures the movement of the bars 12 and the even and odd prisms respectively connected to them in a direction perpendicular to the plane of the screen. The ends of the upper planks and similarly the ends of the lower planks are interconnected by return springs 15, and the movement of the planks 12 is carried out along the guides 14 fixed in the frame 1. The eccentrics 8 provide the separation of the planks and the prisms respectively fixed in them, and the springs - the return of the planks and prisms respectively - in the initial (initial) position. In frame 1, holes 17 are made for moving the axes of the demonstration elements 2.

The device is equipped with a timer that determines the time of the stationary position of the prisms (time period for viewing the advertising image on the screen), rotation sensors of the shaft 5 and the movement of the straps 4 mounted on the shaft 5 and 16, respectively, the signal from which gives a command to turn on and off the engines of the rotation and movement mechanisms .

Advertising design can be performed with lighting devices installed, for example, in the internal cavity of the prisms. In this case, the prisms are made of a transparent or opaque material, for example, painted or unpainted Plexiglas or light-scattering milk acrylic glass. Lighting devices can be installed on the outside of the screen to illuminate it. Screens can be equipped with transparent protective panels. It is possible to carry out prisms with fasteners for fixing the carrier of advertising information from film or paper material. In the case of thin film or paper, they can additionally be pressed with a transparent protective plate. Each prism can be additionally equipped with stiffeners installed in the inner cavity of the prism.

Advertising design works as follows.

Before turning on the device using the timer, set the necessary mode for displaying the advertising image on the screen. Then the voltage is applied to the device, the electric motor of the movement mechanism is turned on, which rotates the shafts 16 with the eccentrics 8, which push the straps 4 apart by the distance necessary to rotate the prisms. In this case, the cams 7 move along the lateral surface of the pushers 6 in the direction of the shafts 5 to a distance that ensures their further interaction. A displacement sensor is triggered, which gives a signal to turn off the engine of the movement mechanism and to turn on the engine of the rotation mechanism, which rotates the shafts 5 with pushers 6, the gear teeth of which engage the gear teeth of the cams 7 and rotate the cams, thereby rotating the prisms 90 ° around the axis . In this case, the shafts 5 are rotated 180 ° and the shaft rotation sensor is triggered, giving a signal to turn off the engine of the rotation mechanism and to turn on the engine of the movement mechanism, which ensures that the eccentrics turn 90 ° and, accordingly, the prisms return to the screen plane under the action of return springs 15 connected to the straps 4. The cycle repeats.

Example.

An advertising structure was made with the following overall dimensions: 1 m wide, 1.2 m high, 0.1 m wide, using prisms with a cross section of 8 × 8 cm. Electric motors of the movement and rotation mechanisms were used KCI-22T4 electric motors, manufactured by Bodine Electric Company, USA.

The proposed design is simple to manufacture and can be used both for outdoor use and for indoor use as an advertising stand with a large information capacity.
