DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Anemostats of various types and designs are known from the prior art and also referred to as ventilation sockets.
In the beginning of the 20^thcentury anemostats designed to control the flow of gases and separation of solid substances were claimed and described. E.g. patent GB, 330 270, published on Jun. 4, 1930 and included in the present claim by way of reference, describes the improvement of separation system by means of device generally referred to as anemostat where a flow is controlled by plates with their bases bent at different angles. Thus it becomes possible to adjust the flow by different incidence angles of flow propagation in various parts of anemostat. The systems utilizing anemostat are described in more detail in patent GB, 323 544, published on Jan. 6, 1930, included in the present claim by reference.
Use of anemostat to control the intake of fresh outdoor air with its simultaneous heating is described in patent GB, 704 447, published on Feb. 24, 1954, included in the present claim by reference. Further the different shape of anemostat plates is used both as a fresh air intake system and for simultaneous ingress of the heated indoor air with the purpose of previous heating of fresh air taken externally.
Since in the course of development of ventilation systems the advantage of complex ventilation in contrast to individual one was proved, a demand was created for elements of ventilation providing the adjustability thus meeting individual needs of various users of the integrated system in a building. Anemostat as element of ventilation system is described in U.S. Pat. No. 2,671,394, published on Mar. 9, 1954, and included in the present claim by reference. In the said patent the anemostat serves as valve to control the air coming from the ventilation system. However flow control did not solve the issue of simultaneous intake of indoor air to compensate for excessive pressure created by charging of the general ventilation system. The search and optimization of the anemostat shape is reflected in ventilation device disclosed in Patent GB 778 447 published on Jul. 10, 1957, included in the present claim by reference. Control of air flow by means of more complicated system as described in Patent GB 909 099 published on Nov. 24, 1962 included in the present claim by reference.
In the course of development of automotive and aircraft industry the attention was paid to ventilation systems (air circulation with further heating or cooling) for passenger compartment of the transport. E.g. Patent GB 768 139, published on Feb. 13, 1957 and included in the present claim by reference, discloses the implementation of such devices utilizing anemostats.
The possibility of controlling air flow by anemostat is used until today.
Gradual architectural change of construction practices from large buildings to more compact ones does imply requires design change of ventilation elements. The reduction of parameters of a building (floor to ceiling height, total area) requires the search for new design solutions in ventilation area. Author's certificate USSR No. 504911 discloses air distributor featuring circular tube with diffuser and air regulator. The improved modification of anemostat has been disclosed in USSR author's certificate No. 694744, published on Oct. 30, 1979. The solution for built-in ventilation systems and suspended ceiling systems has been disclosed in author's certificate of Czechoslovakian Socialist Republic No. 245 409. The search and optimization of anemostat shapes, performance and noise parameters is relevant even today. As disclosed in Patent JP 2008-14526, published on Jan. 24, 2008 and claim US, 2008/0045137, published on Feb. 21, 2008, included in the present claim by reference.
The problem of ventilation is transport of dust particles contained in the air. Considerable volumes of air passing through anemostats require installation of special fixtures to enable easy dismantling/mounting of anemostat parts for cleaning purposes. Claim EP, 104 435, A2, published on Apr. 4, 1984, included in the present claim by reference, describes a distributor which design enables to dismantle parts of anemostat and install them in their respective positions.
Close to this invention is the solution as described in claim PL, 379 603, published on Nov. 12, 2007 and included in the present claim by reference. The anemostat of the said claim consists of mounting tube with guiding holders; frame with threaded hole in the middle thereof, diffuser having mounting tabs thereon with holes and guides; control valve connected to adjusting rod, connected with thread. The disadvantage of the described solution is inconvenience of assembly/disassembly of anemostat parts on the ceiling due to frequent slant in guides, limited number of mounting/dismantling cycles and detachable frame.
A prototype of the present invention is engineering solution as described in patent PL 182 973, B1 published on Dec. 21, 1998. The claimed anemostat consists of such main elements as diffuser, three-beam frame with a threaded hole in the middle thereof, control valve connected with adjusting rod, mounting tube. Additionally the anemostat is equipped with a second diffuser having a three-beam frame with a hole and thread in the centre thereof, frame for additional air flow adjustment. Easy assembling/dismantling of anemostat parts on the ceiling under Patent PL, 182 973, B1, is ensured by fixture elements. To ensure usability and performance characteristics, the fixture elements are attached to the frame by self-tapping screws (or any other fixture elements known from the art).
The disadvantage of the above described solution is a considerable amount of risk of fixture element damage due to slant; increased aerodynamic noise in case of two-level fixation of mounting tube and diffuser; and vibration (turbulent) noise generation as air flow increases due to three-point mounting.
The task of the present invention is to create an anemostat with reliable fastening of diffuser with tube at the same time retaining the possibility of fast and convenient mounting/dismantling of anemostat parts on the ceiling without risk of breakdown of fixture element as a result of skewing; the invention should not have increased aerodynamic noise in case of two-level fastening of tube and diffuser; and it will not generate vibration (turbulent) noise at air flow increase.
The solution of the said task is achieved through anemostat design and particularly its fixture element. According to the present invention the anemostat consists (FIGS. 1 and 2) of control valve (1), threaded adjusting rod (2, diffuser (3), diffuser throat (3′), frame (4), threaded hole (5) on the frame, retaining ring (b) (fixture element) and mounting tube (7). The main element contributing to technical result is a retaining ring (6) which consist of outer rib (a), inner rib (b) and stop plate (c). In the retaining ring (6) (FIG. 3), the stop plate (c) represents a base with outer rib (a) and inner rib (b) thereof.
In the first embodiment under the present invention, the outer rib (a) is formed in the shape of cone i.e. diameter increases from the beginning of the ring (to be considered as stop plate (c)) to the end of the retaining ring. Inner rib (b) is formed in the shape of a cylinder, i.e. the diameter remains the same from the beginning to the end of retaining ring.
In the second embodiment under the present invention, outer rib (a) is formed in the shape of cylinder, i.e. the diameter remains the same from the beginning to the end of retaining ring. The inner rib (b) is formed in the shape of a cone, i.e. diameter increases from the beginning to the end of retaining ring.
In the third embodiment under the present invention, outer rib (a) is formed in the shape of a cylinder, i.e. diameter remains the same from the beginning to the end of the retaining ring. Inner rib (b) is also formed in the shape of cylinder i.e. the diameter remains the same from the beginning to the end of the retaining ring.
In the fourth embodiment under the present invention, the outer rib (a) is formed in the shape of a cone, i.e. the diameter increases from the beginning to the end of retaining ring. Inner rib (b) is also formed in the shape of a cone i.e. the diameter of retaining ring grows from three beginning towards the end.
Thus, all four embodiments as described hereinabove provide adequate fixation of diffuser throat (3′) to the mounting tube (7) by virtue of resilience of the material the stop plate is fabricated from (6) due to smooth and gradual change in dimensions when putting the retaining ring on the diffuser throat (3′) and insertion of retaining ring (6) into the mounting tube (7).
Another additional embodiment under the present invention is any retaining ring from among those described above which has punctures in its inner rib (b) as shown in FIG. 4. Such solution enables to fasten the diffuser (3) to the mounting tube (7). In other words the present embodiment is applicable where diameter of the diffuser throat (3′) is bigger than that of inner rib (b) of the retaining ring (6). The best number of disruptions is three. However it is obvious for a qualified specialist in the industry that increase in diameter of retaining ring (6) will require more disruptions for better performance.
Additional embodiment according to the present invention would be to equip (if needed) the anemostat with an additional diffuser (1′) to be installed on the adjusting rod (2). It is obvious for a qualified specialist in the art that anemostat can be equipped with as many diffusers as needed for designer or user of the engineering solution described herein.
The term “fastening” or “fixation” in the present application shall mean securing one element in relation to the other with possibility of disengaging one element from the other with external action.
The term “resilience” in the present application shall mean a property that is described by resilience theory for material the stop plated is fabricated from.
Unless otherwise defined technical and scientific terms used in the present application shall have the meaning that is generally understood by an expert in the art. Should there be any contradiction or difference between the definitions in this part and those included or cited in any patens, applications, published applications and other publications and definitions obtained from other data bases, the definitions given in this part shall prevail.
