Description

The utility model relates to information presentation devices, in particular advertising information.

A device for displaying information is known that contains trihedral indicator elements arranged in a circle, and their drives are fixed on the axes of the indicator elements, and an electric motor controlled by a programmable command apparatus (UK patent No. 1143511, G 09 F 11/02, 02.26.69)

A disadvantage of the known device is the limited information field (the reverse side of the panel does not carry information) design complexity and the large dimensions of the drive unit of the trihedral indicators.

A device for displaying information is also known, comprising upper and lower bearing housing elements rigidly interconnected, trihedral demonstration prisms arranged in a circle, each face of which contains a fragment of the image, which, together with the corresponding faces of the remaining prisms, constitutes a visible demonstration surface, and installed with the possibility rotation using a drive mechanism associated with an electric motor controlled from the command apparatus, and the drives of each demonstrator The prism prisms are made in the form of bent pins with the possibility of interacting with a pin mounted on an electric motor to rotate each demonstration element by 120 degrees. (Patent RU No. 2152080, G 09 F 11/02, 07/06/98).

However, the demonstration capabilities of the prototype device are limited by the location of trihedral demonstration prisms in

a circle, as a result of which for a stationary observer only a fragmentary vision of a whole image placed on a circular demonstration field is possible. In this case, only three independent images are possible on a circular demonstration field (according to the number of possible variants of the visible set of prism faces).

In addition, the open space between the upper and lower load-bearing housing elements makes the rotation zone of the demonstration prisms unsafe, because does not interfere with the penetration into this zone of people and foreign objects that can cause damage to the device).

The objective of the proposed technical solution is to increase the demonstration capabilities and security of the device.

The problem is solved due to the fact that in the device for displaying information containing rigidly interconnected upper and lower load-bearing housing elements, trihedral demonstration prisms, each face of which, together with the corresponding faces of the other prisms, forms a visible demonstration surface, and mounted with rotation using a drive mechanism associated with an electric motor controlled from a control unit, according to the claimed technical solution, a drive mechanism 3M includes upper and lower rotary nodes pivotally connected to corresponding bearing housing elements, rigidly connected to each other, with which, in turn, trihedral demonstration prisms are pivotally connected from above and below, and the space between the upper and lower bearing housing elements is closed by a transparent fence, installed with the possibility of rotation and / or dismantling.

At the same time, the lower rotary assembly contains gears mounted on the axes of each demonstration prism with

the possibility of engagement with each other and interaction using stops and a crank mechanism with a gear kinematically connected to an electric motor.

The fence can be made in the form of three arcuate flaps pivotally mounted on vertical posts connecting the upper and lower load-bearing housing elements.

The essence of the utility model is illustrated in the drawing, where

- figure 1 shows a General view of the device in a perspective view;

- figure 2 is a vertical section of the device along the Central axis of symmetry;

- figure 3 is a section along the demonstration elements in a top view;

- figure 4 is a top view of the drive mechanism of the device;

- figure 3 - schematically shown in the open state of the curved transparent sash of the fence in a top view.

The device comprises an upper 1 and lower 2 load-bearing housing elements that are rigidly connected to each other by three vertical posts 3. With the upper 1 and lower 2 load-bearing housing elements, the upper 4 (figure 2) and lower 5 rotary nodes are rigidly connected to each other vertical rod 6 (figure 2). Demonstration prisms 7 have (each) an upper 8 and a lower 9 axis, through which the demonstration prisms are pivotally connected to the upper 4 and lower 5 rotary nodes. The total number of demonstration prisms 7 is six and they are installed with the possibility of forming a set of external faces of trihedral prisms of three demonstration surfaces, and in a plane parallel to the bearing housing elements, the demonstration surfaces form a triangle in a plan view (Fig. 4).

Inside the lower supporting housing element 2 with

of the bracket 10, an electric motor 11 is mounted, on the output shaft of which a gear 12 is mounted, which engages with a gear wheel 13 rigidly connected to the lower rotary assembly 5. On the same lower rotary assembly 5, the gear 15, which is engaged with the gear, is pivotally mounted a gear wheel 16, rigidly connected by means of a cup 17 with the lower bearing housing element 2.

The gear wheel 15 using a crank mechanism 18 is kinematically connected with the gear wheel 19, rigidly mounted on the lower end of the axis 9 of one of the six demonstration prisms 7.

In addition, on the axes 9 of each of the demonstration prisms 7 are rigidly mounted with the possibility of engagement with each other gears 20 (figure 4), on which the stops 21 are rigidly mounted, connected by means of springs 22 with levers 23, pivotally mounted on the axes 9 of the demonstration prisms with the possibility of interaction with the grooves of the Central locking disk 24, rigidly connected to the lower rotary node 5.

The device operates as follows.

During the exposition, the demonstration prisms 7 are stationary and, together with their external faces, form three demonstration surfaces. At the end of the exposure time, the electric motor 11 is turned on using the control unit (not shown in the drawing). In this case, the gear 12 starts to rotate and drives the gear 13, which, in turn, rotates the upper 4 and lower 5 rotary nodes that are rigidly interconnected . The gear wheel 15 also starts to rotate around the stationary gear wheel 16 and, by means of the crank mechanism 18, drives the gear wheel 19, which rotates one of the demonstration prisms 7, which, in turn, by

gears 20 engaged with each other, drives the remaining five demonstration prisms 7.

In this case, the demonstration prisms 7 perform a complex movement, namely: together with the upper 4 and lower 5 rotary nodes rotate around the vertical central axis of symmetry of the device for demonstrating information, while performing a rotational movement around its upper 8 and lower 9 axes, each of the demonstration the prism 7 due to the mutual engagement of the gears 20 rotates in a direction opposite to the direction of rotation of the adjacent demonstration prism. Thus, three (out of six) demonstration prisms rotate clockwise, and the other three located between them rotate counterclockwise.

After the demonstration prisms 7 rotate 180 degrees. around their upper 8 and lower 9 axes, and the upper 4 and lower 5 rigidly connected rotary nodes rotate 60 degrees. relative to the upper 1 and lower 2 of the housing load-bearing elements, the control unit turns off the electric motor 11, and the demonstration prisms 7 together with the set of other external faces again form three other visible demonstration surfaces that remain stationary for a given exposure time. In the exposure position, the levers 23 of the demonstration prisms 7 facing outward by sharp angles abut one of their shoulders against the grooves of the central locking disc 24, which is rigidly connected to the lower rotary assembly 5, and gaps are formed between the other leverage arms 23 and the stops 21. In this case, the levers 23 of the demonstration prisms 7, facing inward, abut their second shoulders against the stops 21 and are pressed against the last springs 22.

At the beginning of the movement of the demonstration prisms 7, three of them, which are turned inward, begin to rotate first, and the other three

the demonstration prisms facing outward begin to rotate later when the gaps between the stops 21 and the arms of the levers 23 are closed. Thus, adjacent demonstration prisms at the beginning of their rotation around the upper 8 and lower 9 axes avoid collision with each other at the beginning of the movement.

At the end of the movement of the demonstration prisms 7, the reverse process occurs: three demonstration prisms that stop outward oriented stop the movement in the first place, since their levers 23 abut their first shoulders against the grooves of the central locking disc 24, and three other demonstration prisms 7 stopping inward stop moving later when the set of external faces of the demonstration prisms forms three demonstration surfaces. In this case, gaps are formed between the second shoulders of the levers 23 and the stops 21 of the demonstration prisms. Thus, at the beginning and at the end of the reciprocal rotation of the demonstration prisms, the latter do not collide with each other with their angular edges.

The above movement of the elements of the device occurs periodically. At the same time, for an observer who is motionlessly located on either side of the device for displaying information, six successive successive display surfaces are visible. After successive passage through six demonstration surfaces, the process is repeated again.

When the device is used to demonstrate information, in order to prevent foreign objects and people from getting into the rotation zone of the demonstration prisms, three arcuate flaps 25 hinged on vertical posts connecting the upper and lower load-bearing housing elements are closed, reliably protecting the rotation zone of the demonstration prisms. If necessary (in process

repair, maintenance, image changing on the demonstration surfaces), the shutters 25 are rotated around the vertical racks connecting the upper and lower case elements, providing access to the demonstration prisms.

The inventive design of the device for the demonstration of information can increase the demonstration capabilities and security of the device.
