Description

The invention relates to flags on flagpoles, specifically to flags with a system of their dynamic shaping with the ability to forcibly flutter regardless of weather and atmospheric conditions, as well as location.

In the areas of state symbols and in advertising, devices such as flags, flags, pennants, banners, and other similar products are widely used even in rooms in which the absence of wind prevents the natural waving of the cloth, thus significantly reducing the strength of the reverent awe of citizens before the state symbol and the strength of the advertising impact.

Known flagpoles, which are fixed flags - state or company with emblems and logos [1. US 3798816, IPC G09F 17/00, F04D 25/02, 25/08, publ. 03/26/1974; 2. US 5450811, IPC B60Q 7/00, E01F 9/012, G09F 7/18, publ. 19.09.1995].

Sufficiently close technical solutions to the claimed one are complexes with a forcibly waving flag, containing a flagpole with a device for maintaining the flag in its upper part, and the flagpole is hollow, at least one hole is made in the upper part of the flagpole for supplying compressed air in the direction of the flag, there is a source compressed air, flag raising mechanism and base [3. RU 2482551 C1, IPC G09F 17/00, 05/20/2013, "Flagstaff"; 4. US 3997993, IPC G09F 17/006, G09F 17/00, publ. 12.21.1976].

However, analogs, including [3, 4], have a limitation in the operating mode, do not perform additional important functions, ie. have insufficient technical and operational capabilities (TEV).

On the other hand, inflatable flags are known. An example is an inflatable polyethylene flag for a logo, with a transverse cavity at its base, equipped with a fitting with a plug for inflating this cavity. The latter, when inflated, serves, at the same time, as an inflatable rod [5. Inflatable flag of Russia. - URL: https://p-o-k.ru/catalog/sporttovary_pod_logotip/naduvnye_flagi/; 6. The flag is inflatable. - URL: http://www.fan-wbg.ru/catalog/naduvnoy_flag/].

There is also known a floating craft in the form of an inflatable mattress with the image of the US state flag, while its entire cavity is divided into many identical transverse sections (for reasons of survivability and forced shaping) [7. American flag for the pool. - URL: http://aliextop.ru/g/waves-swimming-pool_2.html].].

However, these products, like all inflatable ones, are static in the absence of external influences on them, including wind and fluid flow.

The closest analogue to the claimed complex-device for its intended purpose and a set of essential design features (the prototype of the claimed complex-device) is a complex of a flag and a system of its forced dynamic shaping, containing a flag in the form of a combination of two identical rectangular panels fixed by a base on a flagpole, and a system of dynamic shaping of the flag, including a source of fluid under pressure, with the possibility of the latter entering the space between the panels from the side of their bases and exiting the specified space on the free cut of the panels, and, as a result, with the possibility of dynamic shaping and waving [8. RU 2416126 C2, IPC G09F 17/00, 04/27/2009 (WO 2006/097565), "A system for forced waving flags for advertising devices and the like and the corresponding methods of its operation", Fig. 6, 6 B, 9, 10, 14A , 16, 17, formula pp. 21, 22].

In the prototype complex, the panels are not connected, but are equidistant to each other with a small gap (a flag with two panels or a group of co-directional flags), while forced waving of both panels, if possible, by longitudinal laminar air flows under pressure, simultaneously in the gap and from the outer sides both panels. The source of fluid medium under pressure is made with the possibility of non-linear, including impulse control of the amount of flow of the fluid at its outlet.

The known prototype device certainly has certain advantages and is more perfect than the previous close analogs, but it also has disadvantages. Thus, the dynamic shaping by jets of both one and a group of parallel non-interconnected panels is unstable under conditions of inevitable turbulence long before the ends of the panels, the mutual influence of panels, especially the combined effect of artificial and natural winds; completely straighten "on a wavy rectangle" only occasionally, often "crumpled"; a significant part of the total flow rate of the fluid flows into the surrounding space, including from the said gap between the panels, not to mention the release of pressure from the left and right of the group of panels. It should be noted that such a disadvantage of the prototype, as the relative complexity and bulkiness of the "multi-tube" blower or other source of fluid under pressure, causing not very satisfactory weight and dimensions of the flagpole as a whole.

The problem lies, as we see, in the insufficient efficiency of technical support for the forced waving of a flag, flag, pennant, etc. products, and, most importantly, the stability of the dynamic shaping of the panel and the efficiency (efficiency) of fluid sources under pressure, and the problem is aggravated in liquid environment (in relation to the symbolism of underwater stationary and mobile objects), plus the dubious expediency of such a massive and dimensional flagpole.

Hence follows the task of the claimed invention: the creation of a device (a set of essential design features) of a complex, partially or completely devoid of the indicated disadvantages of the prototype and other analogs.

Thus, in a more general formulation, the task is to improve the TEI of the complex by improving the shaping of the flag panel, improving the quality and stability of the panel waving, the efficiency of the energy component (with a source of fluid medium under pressure) and the possibility of partial shaping of the panel into calm, as well as simplifying the supply system. fluid medium under pressure, reducing the weight and dimensions of the flagpole.

The designated problem is removed (the problem is solved), with a technical result, the fact that in a complex of a flag and a system of forced dynamic shaping, containing a flag in the form of a combination of two identical rectangular panels fixed with a base on a flagpole, and a system of dynamic shaping of the flag, including itself a source of fluid medium under pressure, with the possibility of the latter entering the space between the panels from the side of their bases and exiting the specified space on a free cut of the panels, and, as a result, with the possibility of dynamic shaping and waving of the panel, according to the claimed invention, the panels are hermetically sealed according to with respect to the fluid, connected to each other along the perimeter to form a hollow two-layer structure, with at least one inlet at the base of the flag for said fluid inlet into the flag cavity, the flag cavity being divided into a common transverse section along the entire width flag at its base, and at least two longitudinal sections on the remaining most of the length of the flag, with each longitudinal section communicating with a common transverse section through vias, and the said outlets are made individual for the sections and are evenly distributed between them in the number of and squares.

The technical result (in accordance with the task) is also achieved due to an additional set of features of the claimed invention: the source of a fluid under pressure can be made with the possibility of non-linear, including impulse control of the flow rate of the fluid at its outlet and, accordingly, at the inlet to the flag cavity (this expands the possibilities to stabilize the "rinsing" of the flag cloth at a quasi-stationary level, to predict and, as a result, to promptly regulate the "behavior" of the flag in conditions of natural wind instability).

A clear delineation of the restrictive and distinctive parts of the given sets of essential features, reflecting the results of a comparative analysis of the proposed set of devices with a prototype, correlate with the world level of novelty of the technical solution. The world level of novelty is the first of the triad of features (criteria) of the invention.

Further, for all its brevity of the wording, the set of distinctive essential features of the claimed complex is not a simple sum of the known technical results of the use of separately known components of the complex. There is a "supereffect" (in the patent meaning of this term), which was not obvious to a specialist from the state of the art achieved (of course, before considering the proposed technical solution). With a whole range of additional technical and operational capabilities. This convincingly demonstrates the inventive step of development as the second of the triad of qualifying features of the invention.

The third qualification feature - industrial applicability - is also indisputable and follows, first of all, from the same accumulated experience in the design, production and operation of various flags and the means of their artificial "revitalization" in calm and light windy conditions.

The inventive complex, using the example of a gas (air) fluid medium, is explained, in addition to the description and operation (operation) given below in the text, by drawings:

in fig. 1 is a semi-schematic view of the "flag - blower" complex, side view, where L and H are the length and width of the flag, respectively; Q is the flow rate of the fluid at the outlet of the fluid source and the inlet into the flag cavity;

in fig. 2 - the same, top view;

in fig. 3 is an exemplary view of a sinusoidal (in time) supply of pressurized air from a blower (as an example of a pressurized fluid supply device) to the flag inlet (s), where Q is the fluid flow rate at the outlet of the fluid source and the entrance to the flag cavity; t is the time of the quasi-stationary (sinusoidal) fluid supply to the flag cavity.

FIG. 1-3 positions indicate: 1 - flag; 2 - the base of the flag; 3 - flagpole; 4 - a source of fluid under pressure; 5 - inlet to the flag cavity; 6, 7, 8 - outlet holes at the end of the flag; 9 - inlet fitting at the base of the flag; 10 - common cross section of the flag; 11, 12, 13 - longitudinal sections of the flag; 14, 15, 16 - intermediate (transition) holes at the entrance to the longitudinal sections of the flag.

The complex of the flag and the system of its forced dynamic shaping contains two component-devices (see Fig. 1, 2).

First, flag 1 in the form of a combination of two identical panels (see Fig. 2) of rectangular shape (length and width L and H, respectively), fixed by base 2 on flagpole 3.

Second, the dynamic flag shaping system 1. It includes a fluid source 4 (air for atmospheric conditions for flag 1, water for underwater flag 1, etc.). In particular, a blower (compressor, fan, receiver, cylinder).

In this case, it is possible for the fluid to enter the space between the panels (see Fig. 2) from the side of their bases 2 (combined according to the further description) and exit from the specified space at the free cut (end) of the panels (see specifically below in the text). And therefore, the possibility of forced dynamic shaping and waving the flag 1.

The webs are hermetically sealed against the fluid and connected to each other along the perimeter to form a hollow two-layer structure. This provides for:

- at least one inlet 5 in the base 2 of the flag 1 for the specified inlet of the fluid into the cavity of the flag 1;

- at least one outlet on the free cut of the flag for the fluid to escape from its cavity (in this example with the Russian flag there are three of them - 6, 7, 8).

The inlet 5, as indicated above, can be the only one and is represented, preferably, by the opening of the fitting 9 for tight connection with the outlet line of the fluid source 4.

The cavity of the flag 1 is divided into a common transverse section 10 along the entire width H of the flag 1 at its base 2, and at least two longitudinal sections (in this example, with the Russian flag, there are three of them - 11, 12, 13) on the remaining most of the length L of the flag 1, while each longitudinal section (11-13) communicates with a common transverse section 10 through intermediate (transition) holes 14, 15, 16, and said outlet holes 6-8 are made individual for sections 11-13 and are distributed between them uniformly in the number of these holes and their areas.

The source 4 of a fluid medium under pressure can be made with the possibility of non-linear, including impulse control of the amount of flow rate Q of the fluid at its outlet and, accordingly, at the inlet 5 into the cavity of the flag 1, specifically into the cavity of section 5 (see Fig. 3) ...

The device works (functions) as follows:

In a calm and with a weak, the more unstable in speed and direction, and even more so in precipitation, wind (as well as indoors), for shaping and waving flag 1 (or other similar products specified above), they are forcibly turned on (or turned on automatically) pressurized fluid source 4.

Fluid medium (in this example - air) under pressure (see Fig. 1, 2)

- enters through the inlet 5 (choke 9) into the transverse common section 10 of the flag cavity 1;

- from there it flows fairly evenly into the longitudinal sections 11, 12, 13 of the flag cavity 1 through the intermediate (transition) holes 14, 15, 16;

- passes in laminar jets in accordance with the walls of the longitudinal sections 11-13, by dynamic and static excess pressures, straightening and expanding the fabrics of flag 1, including in height to compensate for the gravitational action, straightening them in height (the width B of the flag 1 acts as such) and causing its (1) waving at a rectangular configuration of flag 1 (at a given flow rate and amplitude of the fluid medium, including sinusoidal or other pulsation - see Fig. 3, taking into account the resonant frequencies);

- comes out through the outlets 6, 7, 8 at the free end (cut) of flag 1 (opposite to base 2) into the atmosphere.

An additional positive effect can be called the "survivability" of the flag in the event of a leakage of any section (especially from the number of longitudinal), and with small depressurization areas, the leakage rate is small in comparison with the flow rate of the injected fluid.

The technical result consists in the creation of a complex of devices with improved TEI, by improving the shaping of the flag cloth, improving the quality and stability of the waving of the cloth, the efficiency of the energy component (with a source of supplying a fluid medium under pressure) and the possibility of partial shaping of the cloth in calm, simplifying the system for supplying the fluid under pressure, improving the weight and size characteristics of the flagpole.
