The display table contains a main part, an upper part and blades (Fig. 1). The main part is a metal structure consisting of a cross 1, a through inner pipe 17 and an outer pipe 12. The upper part consists of a table top 19 and a metal frame 23.

Four identical legs 2 made of a profile iron pipe with welded wheels 3 are attached to the crosspiece 1 with tightening bolts 4. In the center of the crosspiece 1, a through internal pipe 17 of round cross-section is welded, to which a lower bushing 5 with bearings and an upper bushing 6 with bearings are welded. These bushings 5 and 6 with bearings are designed to slide when the outer pipe 12 rotates around the inner pipe 17. A screw 7 is welded to the upper part of the through inner pipe 17 with its head down, which serves to raise or lower the nut 8. The screw 7 has a thread on which a nut 8 connected to the blades by means of fasteners made of steel strip in the form of rings 13, steel elements 9 and fastenings on the blades 15. When the gearbox 16 is torsed, the outer pipe 12 also rotates directly, thereby rotating the blades. When the blades rotate, the nut 8 rises or falls along the thread on the screw 7, thereby raising or lowering the blades due to the steel elements 9. Steel rods or steel cables can be used as steel elements 9. An outer pipe 12 of circular cross-section is welded to the outer part of the bushings 5 and 6 (the outer pipe 12 of the structure, inside of which there is a through inner pipe 17). Outer pipe 12 can be replaced with 3-4 pieces of profile square pipes. A bushing nut 29 is screwed or put on the upper part of the screw 7 to fix the upper part.

A gearbox 16 (bevel pair) is welded to the bottom of the outer pipe 12, which rotates due to the electric motor 10 attached to it. The electric motor 10 is powered by a battery 11, which is attached to the outer pipe 12. A controller 27 is attached to the battery 11 or to any other place, which serves to start the electric motor 10. A mount for the blades is welded to the top of the outer pipe 12.

The blade mount consists of a steel strip 14, which is an elongated thin and narrow piece of steel. A steel strip 14 horizontally in a circle with the same intermediate distance is welded into a joint with a narrow part to the outer pipe 12, forming a pentagon or hexagon. On the outside of the steel strip 14, a steel rod 30 is welded in the form of a pentagon or hexagon, depending on how many blades there are. Each face of this steel rod 30 in the middle contains a slot 31 into which round fasteners 18 located on the blades are inserted.

To the nut 8 (ball screw nut or any other nut), located on the screw 7, rings 13 are welded for steel elements 9, which are connected to the fastenings on the blades 15. At both ends of the steel element 9 there are hooks with which they are connected to the rings 13 and fastenings on the blades 15. Rings 13 are welded to the nut 8 at equal intervals. The number of rings 13 depends on the number of blades. The fastenings on the blades 15 are also made in the form of rings. Also, the fastenings on the nut 8 can be made differently (two steel strips that are welded to the nut 8 in parallel in a circle, forming a ring around the nut 8. At the ends of these strips there are holes 33 into which fixing bolts 32 are inserted (Fig. 5) When using this fastening option, steel elements 9 engage with bolt 32 between the strips.

The upper part is a table top 19 made of any material, preferably wood, plastic or acrylic. The table top 19 is made in any shape, preferably in the shape of a circle, hexagon or octagon of any diameter. Table top 19 is painted or decorated with sparkles. The table top 19 is screwed with bolts 22 to a metal frame 23. The metal frame 23 is made in the form of a solid disk with a diameter smaller than that of the table top 19, or in the form of a cross made of a profile square iron pipe, in the center of which a sleeve nut 29 is welded, which is also put on the top part of the screw 7, thereby connecting the upper part with the main part.

The frame of the blades is made of 24 aluminum tubes in any shape, such as lotus petals. At the base of the blades there are no less than four curved aluminum tubes 24 (three pieces in length and 1-3 in width). Tubes 24 are connected to each other by wire or welded. The finished blades are covered on the outside with a coating 25, which can be any suitable fabric or any film, for example, holographic. The inside of the blades can be decorated with 26 programmable LEDs that change color. Along the entire outer side of the blades, programmable LEDs 26 (indicated as dots in the figures) can be mounted to the coating 25, which create one large matrix, like an LED screen, which allows you to display various video effects and text. Also, the outer and inner sides of the blades can be decorated with 26 LEDs in the form of any pattern.

At the base of each blade are soldered wires for power that connect to a blade controller 20 and a blade battery 21, which are attached to an outer tube 12. The blade controller 20 is programmed with various effects for the blades.

Also, fasteners 18 are mounted on the blades for connection with the fastener on the outer pipe 12. Fasteners 18 are two rings made of a steel rod, which are attached to the bottom of the blade at a short distance from each other; these rings are inserted in turn into the slot 31 and put on onto rod 30 (first on one side of rod 30, then shifted so that slot 31 is in the middle of fastener rings 18).

There are 24 blades on the central aluminum tube, at a short distance from the bottom of the blade there is a connecting mount 15 for the steel element 9. The bottom of the blade is the part that is attached to the outer pipe 12. There can be any number of such blades, preferably 3-8 pieces .

The device works as follows.

The lighting, video effects, raising, lowering and rotation of the blades are controlled via the radio control panel 28. When the device is turned on, the electric motor 10 rotates the gearbox 16, which is welded to the outer pipe 12, and the blades begin to rotate. When the blades rotate, the nut 8 located on the screw 7 rises up, thereby raising or lowering the blades, which are connected to them by steel elements 9. Rotation in one direction raises the blades, in the other direction lowers them. At the same time, programmed effects are displayed on the blades. The cross 1, the inner pipe 17 and the upper part are static.

Advantages of this device:

- simplifying the design of the demonstration table while ensuring the staticity of the upper part, the cross 1 and the inner pipe 17, the reliability and strength of the structure;

- simplification of the design of the demonstration table is ensured by the fact that complex massive elements are excluded in the main part;

- due to the fact that the upper part, the inner pipe 17 and the cross 1 are static, the demonstration of goods, the display of any show by the artist or any other objects become safer, since the goods or any other object located on the table top 19 will not become loose, and the artist when performing movements (for example, gymnastics) will not lose balance and experience dizziness;

- due to the fact that the upper part, the cross 1 and the inner pipe 17 are static, the objects located on the table top 19 are stable, do not move or vibrate, thereby leading to reliability when using this utility model.
