[0002] AREA OF TECHNOLOGY

[0003] The invention relates to equipment intended to eliminate the impact of shocks and multi-frequency oscillations on vibration-sensitive equipment. More specifically, to devices for installing electronic equipment subject to the negative impact of rhythmic oscillations and single shocks arising in the environment and transmitted through objects with which this equipment is in contact. The claimed invention completely absorbs vibrational energy waves emanating from the environment and provides vibration isolation. The invention can be used to place audio, video equipment, electronic equipment in seismically active areas and other electronic units, optical and mechanical devices sensitive to the negative impact of rhythmic oscillations and single shocks arising in the environment.

[0004] PRIOR ART

[0005] Currently, there is a tendency towards a widespread increase in the use of high-precision and highly sensitive devices and systems in various fields of science and industry. Due to the constant and widespread presence of shock and multi-frequency vibration sources (working people, equipment, buildings and systems installed in them, transport, etc.), there is a need to develop a reliable, effective and low-maintenance device designed to effectively isolate highly sensitive and high-precision devices from the adverse effects of shock and vibration.

[0006] Various racks for installing electronic equipment are known, the manufacturers of which, due to the special designs of their racks") try to combat the negative impact of rhythmic oscillations and single shocks that occur in the environment. The closest, in terms of the totality of existing features, analogue to the claimed invention (prototype) is the rack for electronic equipment manufactured by Wes Bender Studio NYC, http: / / www.wesbenderstudionyc.com / stillpoints

[0007] This rack consists of a frame made in the form of a pair of masts, between the arm and the support of each of which there are pre-tensioned connecting cables. On each pair of cables, solid support rods and hollow rail grids are rigidly fixed. The disadvantages of this product are: Tensioned cables, solid support rods made of stainless steel, as well as a large number of hollow rail grids contribute to both the transmission of external vibrations and resonances from the environment and from other electronic equipment located in the rack, and the generation of their own vibrations and resonances in a very wide frequency range, which negatively affects the sound quality of the audio equipment and its perception by the user.

[0008] At the same time, this manufacturer, having made a stand, the design of which reduces the impact of rhythmic vibrations and single shocks on the electronic equipment installed on it, additionally produces a wide range of vibration-isolating devices for it.

[0013] THE BEST OPTION FOR IMPLEMENTING THE INVENTION

[0014] The rack according to the first variant consists of a frame. The frame includes a support 1 rigidly connected to at least one horizontal crossbar 2. The frame can be made of metal, wood, various types of polymer composite materials and their combinations. The support 1 is rigidly connected to the power crossbar 2 using an adhesive, welded, screwed connection and their combinations. The frame of the frame is a rectangular structure consisting of at least one vertical guide and at least one horizontal bar connected to it. In a specific example of execution, which does not limit the scope of legal protection, the frame is made in an L-shape, is a support 1 to the top of which one crossbar 2 is attached by a welded joint. In another example of execution, which does not limit the scope of legal protection, the frame is made in a T-shape (not shown in the Fig.) is a support 1 to the middle part of which one crossbar 2 is attached by a welded joint.In another example of execution, which does not limit the scope of legal protection, the frame is made F-shaped (not shown in the Fig.) and is a support 1, to the upper and middle parts of which two crossbars 2 are attached by a welded joint. Also, the frames can be made E-shaped, 1-shaped, T-shaped and of other shapes, respectively. Stops 3 are placed in the lower part of the support 1. Stops 3 can be made in the form of legs adjustable or non-adjustable in height, wheels with or without stoppers. Stops 3 can be mounted with a plastic end cap with a felt self-adhesive gasket of large thickness glued to it. This ensures a reduction in resonances of both the rack itself and a minimization of the level of vibrations transmitted to the support 1 of the rack from the base on which it is installed. At least two fastening units 4 are installed on the horizontal crossbar 2.In a specific example of execution, which does not limit the scope of legal protection, slot stoppers secured to a horizontal crossbar 2 with screws are used as a fastening unit 4. Cable stays 5 are fixed in the fastening units 4. Cable stays 5 are intended for placing electronic equipment on them, subject to the negative influence of rhythmic vibrations and single shocks occurring in the environment, or shelves for placing said electronic equipment. In this case, the electronic equipment or shelves for placing it are attached to individual cable stays 5 using rings, pins, hooks and other elements or on cable stays 5 stretched between the fastening units 4. Cable stays 5 are an elastic material in the form of tapes, cords, cables, strands, ropes and combinations thereof. A combined cable stay 5 as one of the examples of execution is made of an elastic cord in the middle part connected to the elastic cord by clamps (as shown in Fig. 7).The combined shroud 5 as another example of execution is made in the form of an elastic cord consisting of latex threads covered on the outside with a braid made of polypropylene. In a specific example of execution, not limiting the scope of legal protection, a rep-cord with an elongation coefficient of 3-5% is used as the shroud 5. The shroud 5 is fixed on fastening units 4 opposite each other with the possibility of adjusting its length.

[0015] The rack according to the second embodiment consists of a frame. The frame includes at least two supports 1, rigidly connected to each other by at least one horizontal crossbar 2. The frame can be made of metal, wood, various types of polymer composite materials and combinations thereof. The supports 1 are rigidly connected to the horizontal crossbar 2 using an adhesive, welded, screwed connection and combinations thereof. In one example of execution, which does not limit the scope of legal protection, the frame is made of two C-shaped supports 1 (Fig. 1) connected in the middle part by a horizontal crossbar 2. In another example of execution, which does not limit the scope of legal protection, the frame is made of two U-shaped supports 1 (Fig. 2) connected in the lower part by a horizontal crossbar 2. In another example of execution, which does not limit the scope of legal protection, the frame is made of two U-shaped supports 1 (Fig. 3) connected in the upper part by a horizontal crossbar 2.In another example of execution, which does not limit the scope of legal protection, the frame is made of two H-shaped supports 1 (Fig. 4) connected in the upper and lower parts by horizontal crossbars 2. Also, the frames can be made of H-shaped, L-shaped, L-shaped and other shapes of supports. Stops 3 are placed in the lower part of the support 1. Stops 3 can be made in the form of legs adjustable or non-adjustable in height, wheels with or without stoppers. Stops 3 can be mounted with a plastic end cap with a felt self-adhesive gasket of large thickness glued to it. This ensures a reduction in resonances of both the rack itself and a minimization of the level of vibrations transmitted to the supports 1 of the rack from the base on which the electronic equipment is installed. At least two fastening units 4 are installed on the horizontal crossbar 2 or on opposite parts of the supports 1.In a specific example of execution, which does not limit the scope of legal protection, slot stoppers secured to a horizontal crossbar with 2 screws are used as a fastening unit 4. Cable stays 5 are fixed in the fastening units 4. Cable stays 5 are intended for placing electronic equipment on them, subject to the negative influence of rhythmic vibrations and single shocks occurring in the environment, or shelves for placing said electronic equipment. In this case, the electronic equipment or shelves for placing it are attached to individual cable stays 5 using rings, pins, hooks and other elements or on cable stays 5 stretched between fastening units 4. Cable stays 5 are elastic material in the form of tapes, cords, cables, strands and their combinations. In a specific example of execution, which does not limit the scope of legal protection, a rep-cord with an elongation coefficient of 3-5% is used as a cable stay 5.The guy rope 5 is secured to fastening units 4 opposite each other with the possibility of adjusting its length.

[0016] The rack is assembled as follows. A frame is formed from a support 1 with a horizontal crossbar 2 or from at least two supports 1 with a horizontal crossbar 2. If there are stops 3, they are fixed to the lower part of the supports 1. At least two fastening units 4 are installed on the horizontal crossbar 2 or on the supports 1 in the upper part, when making a frame from at least two supports 1. Cables 5 are fixed in the fastening units 4 or each cable 5 is fixed with one end in the fastening units 4, and with the other on the electronic equipment or shelves for its placement using rings, pins, hooks and other elements. The vibration energy emanating from the environment is absorbed by the cables 5. Vibration isolation is provided due to the inertial force of the electronic equipment freely suspended on the cables 5 and the shock-absorbing effect of the stretching coefficient of the cables 5.

[0017] INDUSTRIAL APPLICABILITY

[0018] A rack for installing electronic equipment exposed to the negative influence of rhythmic vibrations and single shocks arising in the environment is a system of horizontal and vertical elements that interact with each other to provide the necessary strength and stability. The claimed invention is based on the principle of balance of forces. It consists of horizontal elements that are supported by vertical elements called a frame. Cables 5 are positioned at an angle to the horizontal and take on part of the load, transferring it to the frame. The principle of operation of cable-stayed structures is that cables 5 take on rhythmic vibrations and single shocks arising in the environment. These forces are distributed along the length of cables 5. The design of the claimed invention provides the ability to fix blocks at any height required by the user. The absence of rigidly installed shelves allows you to take advantage of this advantage.This design advantage allows to significantly improve the ventilation mode and temperature balance of the operating units of electronic equipment. The height of placement between the units in the rack should take into account only the sufficiency of the height to obtain sufficient convection for the thermal balance. This, in the absence of rigidly installed shelves, will allow the most compact placement of the units of electronic equipment. The purpose of the invention is to eliminate the rigid mechanical connection of the rack with the electronic equipment, through which vibrations and oscillations from the surrounding space, in the frequency range that have a negative effect on the quality of operation of each device, are able to reach the electronic equipment. This can be achieved by hanging each unit on the rack frame on freely hanging elastic cables 5.The lightweight, freely hanging elastic cables 5 structurally exclude by 100% the possibility of transmitting external vibrations, resonances and acoustic oscillations in any planes to the equipment that has a greater mass, compared to the cable mass. The mass of the unit, by means of freely hanging elastic cables 5, deprived of a rigid connection through its own legs (supports) with the rest of the system, will allow the suspended unit of electronic equipment to stabilize its state with the help of the force of inertia and the force of gravity of the Earth, which will provide it with a stable motionless state, and accordingly provide the maximum level of audio-video signal quality laid down by the manufacturer. Even if the rack, in the places of fastening of cable 5 to the rack, will affect cable 5 in the form of vibrations, resonances and acoustic oscillations in any planes, then this will occur relative to the motionless hanging unit of electronic equipment.
