Description

The invention relates to advertising and may be used in billboards displaying information signs or drawings on rotating elements.

Known billboards having triangular prisms and their turning mechanisms with roller chains that rotate the stars on the axis of the prism (USSR Auth. No. 943823, GO9F 11/23, 1980) or with gear (U.S. Pat. No. 3). 199 239, NPK 40-76, 1965), wherein the rotational motion is transmitted from one prism pinion to another prism pinion.

These billboards have the common main disadvantage of making a lot of noise and therefore need regular lubrication to reduce it. This is very inconvenient and especially if such stands are installed on walls, roofs, in shop windows and so on.

Also known is a billboard having a series of triangular prisms with axes at their ends, which are inserted into the frame, and a prismatic pivoting mechanism with belt gears where the rotational motion is transmitted from one prismatic toothed pulley to another prismatic pulley (U.S. Pat. 4189859, GO9F 11/02, 1980).

This billboard does not have the disadvantages of the aforementioned stands, but the prism rotation mechanism does not provide the same turning angle for all the prisms, which makes the front sides of the prisms not always in one plane, which reduces the visual quality of the information presented.

Also known is a billboard (European Patent No. EPO 202469, GO9F 11/02, 1986) which has been patent pending since U.S. Pat. 4189859 differs in that, in order to avoid said disadvantage, the prismatic pulleys receiving and transmitting the rotary motion are twofold, i.e. each of them being part of a double pulley and thus avoiding rotation between them. In addition, this dual pulley has a clamp that clamps the prism axis neck, which allows the faces of the individual prisms to be flattened into a single demonstration plane.

However, the latter and all the other stands mentioned above cannot dynamically form and format the information text or drawing.

In technical terms, the closest billboard (U.S. Pat. No. 3304638, NPK 40-76, 1967) having a frame, a plurality of polygonal prisms with axes at their ends, which are inserted into the mounting bar, and a prismatic rotating mechanism having a shaft mounted on the its number of prisms in discs with fingers disposed radially of unequal length, interacting with the stars fixed on vertically sliding axes of springing prisms at one end of the prisms, whose fingers are radially disposed in different planes.

This billboard is equipped with discs of uneven lengths on the spindle shaft and vertically sliding spring prism axes with sprockets in different planes to prevent damage to the spindle when trapped between prism foreign objects, in which case the longest disc finger striking the prism axis rigidity, raises the prism upward and continues to remain unturned until the obstacle is removed, while other prisms can then be rotated. However, this advantage does not compensate for the deterioration in the visual quality of the stand. In this case, the obstacle must be removed promptly. Meanwhile, damage to the torsion mechanism can be prevented by simpler known means.

Also, this stand cannot dynamically form and format information text or drawing. Another major drawback is that it is not possible to ensure a uniform angle of rotation for all prisms and to capture their stable position after rotation of the prisms, which damages the display plane of the booth and thereby degrades the visual quality of the information.

The object of the invention is to extend the functionality of the stand and to improve the visual quality of the information provided.

This object is achieved by a known billboard frame having a plurality of polygonal prisms with axes at their ends, which are inserted into a mounting cross member and a prismatic rotating mechanism having a shaft mounted on it according to the number of prisms with radially disposed fingers interacting with the anchors. on the axes of the prisms, at one end, with sprockets with radial operating supports, the fingers of said discs are fixed to the pivotable shaft and locked to the disc segments, and a prism position locking device is provided having pins on respective prism axes with corresponding planes are parallel to one of the prism walls, and are fixed to the cross-member by spring-loaded latches whose plane is simultaneously in contact with the cam of two adjacent prisms.

The drawing shows an example of a billboard implementation where:

FIG. 1 - Front view of the stand;

FIG. 2 - cross-sectional view of the prize wrench;

FIG. 3 is a bottom view of the star of the prismatic rotating mechanism;

FIG. 4 is a side view of a prism locking device;

FIG. 5 is a top view of a prism locking device.

The billboard has a frame 1, polygons, such as triangles, prisms 2, whose front sides 3 form a demonstration plane, with upper 4 and lower 5 axes, which are inserted into sliding or roller bearings mounted in the mounting rails 6 and 7, having a prismatic rotation mechanism a motor 8, a protective sleeve 9, a shaft 10 on which disks 11 with radially spaced fingers 12 mounted on pivotable shafts 10 and secured to segments 11 of discs 11 having uniform curvature with respect to shaft 10 are mounted, screwed in and threaded into the disk threaded holes by means of bolts 15 for attachment of segments 13 (not shown) and sprockets 16 mounted on lower prism axes 5 having three recesses 17 with radial working surfaces 18 and slots 19, and a prism positioning device 2, having on the prisms v and locking pins 21 with locking nuts 20 with three planes 22, each parallel to one of the prism flanks 3, and locking pins 23 mounted on pins 24 with pins 25 and touching simultaneously two prism pins 21.

The number of notches 17 of the fingers 12 and the stars 16 of the discs 11 may be different from those shown in the drawing, for example, one finger 12 and one notch 17.

The billboard works this way. The rotational movement from the motor 8 is transmitted through the protective sleeve 9 to the shaft 10 with discs 11 and fingers 12 which enter through the slots 19 into the notches 17 of the star 16 and rotate the prism 2 through axis 5 until the other side of the prism coincides. with a bench demonstration plane. The prism 2 rotates with its upper axis 4 with a cam 21 which rotates through the latch 23, overcoming the resistance of the spring 25, until it comes into contact with its other plane 22 with the latch 23 which simultaneously engages the two cam planes. position 2 of adjacent prisms. The finger 12 then exits the notch 17 of the sprocket 16 and depresses the shutter, which turns off the motor 8 and activates the timer (not shown) for the desired exposure time.

If the fingers 12 of all discs 11 are aligned in a line along the shaft 10, all the prisms 2 are rotated together by 120 °. By rotating the segments 13 of the discs 11 relative to the shaft 10 it is possible to change the angle of the fingers 12 with respect to each other on one disc, the disks 11 of the other discs 11 and 1.1. This ensures that the prisms 2 are rotated independently of one another, which allows the rotation mechanism to be adjusted so that the prisms 2 can be rotated one after the other, i.e. wave or several waves at once in any direction of rotation.

When the foreign object is caught between the prisms 2, the protective sleeve 9 disconnects the shaft 10 from the motor 8 and the rotation of the prisms is interrupted until the object is removed.

The use of the present invention makes it possible to extend the functionality of the billboard, i. change advertising or informational text or drawing immediately or progressively, while ensuring the visual quality of the information provided by a simple prismatic positioning device in which the latch is in constant contact with the two cam and therefore does not require precise selection of spring presses or other adjustments.
