Known devices for viewing in the form of a Ferris wheel according to US Pat. RF №2026705 dated 01.02.1995 and №2109543 dated 04/27/1998

Ferris wheel according to US Pat. RF №2026705 consists of a base, a circular farm with a horizontal axis of rotation and visitor cabins suspended around its circumference.

A disadvantage of the known device is the relatively small height of the cabs and, as a consequence, the small viewing area.

A device for viewing according to patent FR No. 2820397 A1, 08/09/2002, which consists of a base, a passenger cabin and a lift in the form of an airborne aircraft (VLA) is lighter than air (LV), is known.

In turn, the well-known VLA LV contains a tethered balloon filled with gas lighter than air. Also, the device is equipped with a mechanism for raising and lowering it and is configured to hold it on the base in the "berth" mode.

A disadvantage of the known analogue is the relatively large time required to bring it into working condition, which reduces its mobility.

The closest in technical essence to the claimed technical solution is a known device for viewing, containing the base, passenger cabin and a lift. As a lift, VLA LV was used, made in the form of a tethered balloon containing a shell filled with light gas with a passenger cabin. The balloon is connected via cables to the mechanism of its ascent and descent. The device is also equipped with a latch holding the VLA of the LV on the base in the “berth” mode.

The disadvantage of the closest analogue is the relatively low mobility associated with the need to carry out a significant amount of work on its installation, which also requires a significant area for its installation, which in many cases precludes the possibility of its use in urban conditions. The fixed position of the device (its cabin) in the raised position makes it difficult to have a panoramic view of the terrain.

The aim of the invention is the development of a mobile device for viewing the panorama of the area, providing more favorable conditions for a circular view of the opening panorama.

The claimed device extends the arsenal of funds for this purpose.

This goal is achieved by the fact that in the known device for viewing, containing a base, a passenger cabin and a lift, which is used VLA LV, made in the form of a tethered balloon containing a shell filled with light gas with a passenger cabin and connected via ropes with a mechanism for lifting it and descent (MPS), moreover, the device is equipped with a latch holding the VLA of the aircraft on the base in the “berth” mode, the MPS consists of a reversible engine (RD). The RD power shaft is connected to the axes of freely rotating drums with ropes wound on them by means of a gear transmission (ШП). The outer ends of the cables through the corresponding locks at the base are connected to the VLA LV.

Also new is the fact that the latch is made up of passive and exciting elements. A passive element (PE) in the form of a vertical rod with its upper end mounted on the outer surface of the lower wall of the PC. Through a lock in the center of the base, the PE interacts with the locking element (SE) of the retainer, which is located under the surface of the base.

The base of the device is made with the possibility of its rotation in the azimuthal plane. The base consists of two congruent sites spaced in height. In the gap between the sites on the lower platform fixed MPS VLA LV.

Thanks to a new set of essential features, it is possible to install and install the device in a relatively short time on small sites. The operation of the device minimizes material costs, because the rise of VLA LV occurs due to the aerostatic lifting force of VLA LV. The aforementioned indicates the possibility of implementing the formulated technical result.

The analysis of patent and special sources of information made it possible to establish that they lack analogues that are characterized by a combination of features that are identical to all the essential features of the claimed solution, which indicates its compliance with the patentability condition of “novelty”.

Search results for known solutions in this and related fields of knowledge in order to identify the distinguishing features of the claimed object showed that they do not follow explicitly from known sources of information. Also, the popularity of the influence of distinctive essential features on the achievement of the formulated technical result was not revealed, which indicates the compliance of the claimed object with the patentability condition "inventive step".

The claimed device is illustrated by drawings, which show:

figure 1 - General view of the device in flight mode;

figure 2 - General view of the device in the mode of "berth";

figure 3 is a design variant of the base of the device;

figure 4 is a design variant of the mechanism for lifting and lowering the VLA LV.

The viewing device shown in FIG. 1 (“flight” mode) and FIG. 2 (“berth” mode) consists of a base 1, a VLA LV including a shell 2, and a PC 3. In particular, shown in FIG. 1 , 2 VLA LV is made in the form of a tethered balloon, the shell 2 of which is filled with light gas (for example, hydrogen, helium, heated air, etc.). The balloon is in a completed state, i.e. in a state of full filling of the shell 2 with gas.

The soft shell 2 of the balloon can be made of polyester alluminized fabric and coated with polyurethane to give greater tightness. In order to ensure flight safety, the inner volume of the shell is partitioned, and each section is equipped with a check valve, which eliminates a significant reduction in aerostatic lifting force in case of violation of the integrity of the shell of any of its sections.

PC 3 is mounted on the shell 2 of the balloon using Kevlar cables 4. PC 3 is closed and equipped with wide windows 5 (figure 2). Inside PC 3, seats for passengers (not shown) can be installed.

The lower part of the shell 2 at the mounting point of the PC 3 is reinforced with a substrate of high-strength synthetic Kevlar material (not shown). The upper part of the shell 2 is provided with a similar reinforced substrate to give it greater reliability when a higher excess gas pressure is applied in this part of the shell (not shown).

An additional mesh can be worn on the shell 2, which serves to hold the shell 2 in the aerostat system, maintain its shape and to suspend the PC 3 and other necessary equipment.

Design features and methods for calculating the lift of balloons are known and described, for example, in the book: Aris M.Ya., Polyanker A.G. A new generation airship. - Kiev, Naukova Dumka, 1983.- p.16-25.

VLA LV is connected using Kevlar cables 6 to the MPS shown in figure 3, 4.

The base 1 of the device (figure 3) is made in the form of two congruent upper 7 and lower 8 sites, spaced in height by a distance of h. The base 1 is made with the possibility of its rotation in the azimuthal plane. For this purpose, the base is equipped with an azimuthal rotation mechanism consisting of an engine 9 and a gear pair comprising a gear 10 fixed to the outer surface of the lower platform 8 of the base 1, and a gear gear 11 mounted on the motor shaft 9. To ensure free and smooth rotation of the base 1 is equipped with freely rotating wheels 12 and mounted on an annular monorail 13 (figure 3). The azimuthal rotation mechanism is located in the pit 14, equipped under the center of the base.

In the interval between the lower 8 and upper 9 sites installed MPS (figure 3, 4).

MPS is installed on the inner surface of the lower platform 8 of the base 1. MPS consists of a reversible engine 14, two gears (ШП) 15 and four freely rotating drums 16 with corresponding cables wound 6. The drums 16 are mounted symmetrically relative to the center of the platform 8 on mutually perpendicular diameters. ШП 15 are intended for transmitting the torque of the power shaft of the engine 14 on the axis of the drums 16. The upper platform 7 of the base 1 is equipped with peripheral locks 17 above the mounting locations of the corresponding drum 16 (Figs. 1, 3) and a central lock 18. Ropes 6 are passed through the locks 17, the ends of which are fixed on the shell 2 VLA LV. The rotation of all the drums 16 from one drive-motor 14 ensures the synchronism of unwinding the cables 6 and the smoothness of the rise of the VLA LV.

The device is equipped with a latch, consisting of a passive 19 and exciting 20 elements (Fig.2, 3, 4).

Passive element (PE) is designed for stable fixation of VLA LV in the "berth" mode and is made in the form of a rod, with its upper end fixed to the bottom wall of PC 3 (point "a" in figure 2). The gripping element (ZE) 20 is installed in the center of the lower platform 8 of the base 1. ZE 20 consists of a pair of spring-loaded grippers (PP) 21, mounted on the axes 22 and the lower ends connected to the release element (ER) 23 of the latch.

As the ER 23, a solenoid with a pair of levers actuated when the ER 23 is connected to a control voltage source (not shown) can be used. PE 19 and ZE 20 interact when mooring the VLA of the drug through the central gateway 18.

A device for viewing works as follows. In the initial position (“berth” mode), the retainer PE 19, through the central lock 18, is immersed in the space between the upper 7 and lower 8 platforms of the base 1, fixed and held by a pair of PZ 21.

Cables 6 are fully selected and wound on drums 16. After placing passengers in PC 3, the “flight” mode begins. To do this, the control voltage is supplied to the SE 20. ER 23 is activated, diverts P3 21 from PE 19, thereby unlocking PE 19. At the same time, turn on RD 14 and synchronize the rotation of the drums 16 through the SS 15, freeing the cables 6. Under the action of aerostatic lifting force the rise of VLA LP to a given height N, after which RD 14 is turned off. The VLA of the aircraft is held at a predetermined height by a balancing force, depending on the mass of the VLA of the aircraft itself, the mass of the payload (mass of all passengers) and the full aerostatic lifting force. The procedure for calculating the listed values and the methodology for calculating the equilibrium state of the drug VLA are known and described in the above book Aris M.Ya. and Polyanikera A.G. on pp. 16-21.

After reaching a predetermined height H, the azimuthal rotation mechanism is turned on by supplying a supply voltage to the engine 9. The speed of the base 1 is selected in the range of 0.25-1.0 revolutions per minute. The required speed is determined by the gear ratio of the interacting pair of gears 10 and 11. After the panorama is complete, the azimuthal rotation mechanism is turned off. The reverse polarity voltage is applied to the RD 14 input, the VLA of the LV decreases with the help of ropes 6, wound around the synchronously rotating drums 16. After entering through the central lock 18 PE 19 and fixing it with the help of the PZ 21, the VLA of the LV returns to its initial position - the “ berth ".

Thus, the device does not require a large area for deployment and can be mounted and dismantled in a short period of time, which makes it mobile. The aforementioned indicates the possibility of achieving the formulated technical result.
