Description

TECHNICAL FIELD

[0001] The present invention relates to a device designed to eliminate the effect of impacts and oscillations of different frequencies on vibration-sensitive devices. More specifically, the invention relates to a device for mounting electronic equipment, which is negatively affected by rhythmic oscillations and single impacts occurring in the surrounding environment and transmitted through objects in contact with the device. The claimed invention completely absorbs oscillation energy waves originating from the environment and provides vibration isolation. The invention can be used for mounting audio and video equipment, electronic equipment in seismically active areas, and other electronic units, optical and mechanical instruments sensitive to rhythmic oscillations and single impacts occurring in the environment. BACKGROUND

[0002] At present, there is a widespread trend in various fields of science and industry to use increasingly high-precision and high-sensitivity instruments and systems. Due to the constant presence of sources of impacts and oscillations of different frequencies (people at work, machinery, buildings and their internal systems, vehicles, etc.), there is a need to develop reliable, efficient and cost-effective devices that can effectively isolate high-sensitivity and high-precision instruments from the adverse effects of impacts and vibrations.

[0003] Various stands for mounting electronic equipment are known, the manufacturers of which try to offset the negative effects of rhythmic oscillations and single impacts occurring in the environment through the special design of their stands. The closest analogue to the claimed invention (prototype) is a stand for electronic equipment manufactured by Wes Bender Studio NYC (http: / / www.wesbenderstudionyc.com / stillpoints).

[0004] The stand consists of a frame made in the form of a pair of columns, between the arm and the base of each column a pre-tensioned connecting cable is mounted. A solid support rod and a grid of hollow rails are rigidly fixed on each pair of cables. The disadvantages of this design are as follows: the tensioned cables, the solid stainless steel support rod and the large grid of hollow rails contribute to the transmission of external vibrations and resonances from the environment and from other electronic equipment placed in the stand, as well as the generation of self-induced vibrations and resonances on a very wide frequency spectrum. This negatively affects the sound quality of audio equipment and its user's perception.

[0005] At the same time, the manufacturer produces a variety of vibration isolation accessories for the stand, the design of which reduces the impact of rhythmic oscillations and single impacts on the mounted equipment. SUMMARY

[0006] The authors of the present invention set the goal to create a rack that completely blocks the transmission of vibrations and resonances from the rack to the mounted equipment and between the electronic units, while eliminating the disadvantages inherent in the analogues of the prior art. The technical result achieved in solving this goal is the ability to mount electronic equipment to the rack without any rigid mechanical connections, thereby eliminating the physical transmission of external vibrations and resonances from the environment and adjacent electronic units in the same rack. This technical result is achieved by the combination of all the necessary features.

[0007] The essence of the invention is that the cable support rack comprises a frame comprising support elements rigidly connected to at least one horizontal crossbar, wherein the horizontal crossbar is equipped with at least two fastening nodes for fixing the cables. The cables are fixed in the fastening nodes at both ends, or one end of each of the cables is fixed in the fastening nodes, and the other end has a fastening element, wherein the cables are made of an elastic material. Alternatively, the cable support rack comprises a frame comprising at least two support elements rigidly connected to each other by at least one horizontal crossbar, wherein each of the support elements has at least two fastening nodes mounted on it, and the cables are fixed in the fastening nodes at both ends, or one end of each of the cables is fixed in the fastening nodes, and the other end has a fastening element, wherein the cables are made of an elastic material. The frame is made of metal, wood, polymer or their combination. The support elements and the horizontal crossbar are joined by adhesives, welding or threaded connections or their combination. The support elements have stops at their base. The stops are made in the form of adjustable or fixed height legs with or without a brake, wheels. One end of the cable is further provided with a fastening element for a loop, pin, hook. The cable is made in the form of a belt, rope, cord, strand or their combination. The cable is made of an elastic material with a stretch coefficient of at least 3-5%. In addition, the cable is fixed in the fastening nodes in such a way that the length of the cable can be adjusted. BRIEF DESCRIPTION OF DRAWINGS

[0016] The stand according to the first embodiment comprises a frame. The frame comprises a support 1 rigidly connected to at least one horizontal crossbar 2. The frame can be made of metal, wood, various types of polymer composites and combinations thereof. The support 1 is rigidly connected to the load-bearing crossbar 2 using adhesives, welding or threaded connections or combinations thereof. The frame is a rectangular structure consisting of at least one vertical guide and at least one horizontal bar connected to the at least one vertical guide. In one embodiment without limiting the scope of legal protection, the frame has an L shape and denotes the support 1, one crossbar 2 is attached to the top part of the support 1 by a welded connection. In another embodiment without limiting the scope of legal protection, the frame has a T shape (not shown in the figures) and denotes the support 1, one crossbar 2 is attached to the middle part of the support 1 by a welded connection. In another embodiment without limiting the scope of legal protection, the frame has an F shape (not shown in the figures) and denotes the support 1, two crossbars 2 are attached to the upper and middle parts of the support 1 by a welded connection. The frame can also have an E shape, an inverted L shape, an inverted F shape and other shapes, respectively. A stopper 3 is placed in the bottom part of the support 1. The stopper 3 can be made in the form of adjustable height or fixed height legs, wheels with or without brake parts. The stopper 3 can be equipped with a plastic end cap with a thick felt self-adhesive pad glued to it. This ensures the reduction of the resonance of the stand itself and the minimization of the vibration level transmitted to the support 1 of the stand from the base on which the support 1 is installed. At least two fastening nodes 4 are installed on the horizontal crossbar 2. In one embodiment without limiting the scope of legal protection, the slot stoppers fixed to the horizontal crossbar 2 with screws are used as fastening nodes 4. Cables 5 are fixed in the fastening nodes 4. The cables 5 are intended for placing electronic devices on them, which are negatively affected by the rhythmic oscillations and single impacts occurring in the environment, or for placing shelves for electronic devices. In this case, the electronic devices or the shelves for their placement are attached to the individual cables 5 using loops, pins, hooks and other elements, or to the cables 5 stretched between the fastening nodes 4. The cables 5 are in the form of elastic materials such as belts, ropes, cords, strands or combinations thereof. In one embodiment, the combined cable 5 is made of one elastic rope connected to another elastic rope in the middle part by a clamp (as shown in Figure 7 ). In another embodiment, the combined cable 5 is made in the form of an elastic rope consisting of a latex line covered with a polypropylene braid on the outside. In a particular embodiment without limiting the scope of legal protection, a rope with a stretch coefficient of 3-5% is used as a cable 5. The cables 5 are fixed to the fastening nodes 4 opposite each other, the length of which can be adjusted.

[0017] The stand according to the second variant comprises a frame. The frame comprises 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 composites or combinations thereof. The supports 1 are rigidly connected to the horizontal crossbar 2 using adhesives, welding or threaded connections or combinations thereof. In one embodiment without limiting the scope of legal protection, the frame is made of two C-shaped supports 1 connected in the middle part by a horizontal crossbar 2 Figure 1 . In another embodiment without limiting the scope of legal protection, the frame is made of two U-shaped supports 1 connected in the bottom part by a horizontal crossbar 2 Figure 2 . In another embodiment without limiting the scope of legal protection, the frame is made of two inverted U-shaped supports 1 connected in the top part by a horizontal crossbar 2 Figure 3 . In another embodiment without limiting the scope of legal protection, the frame is made of two rectangular A-shaped supports 1 connected in the top and bottom parts by horizontal crossbars 2 Figure 4 . In addition, the frame can have the shape of H, L, inverted L or any other shape. At the bottom of the supports 1, stop elements 3 are placed. The stop elements 3 can be made in the form of adjustable height or fixed height legs, wheels with or without a brake. The stop elements 3 can be installed with a plastic end cap with a thick felt self-adhesive pad glued to it. This ensures a reduction in the resonance of the stand itself and minimization of the level of vibrations transmitted from the base on which the electronic equipment is installed to the supports 1 of the stand. At least two fastening nodes 4 are installed on the horizontal crossbar 2 or on the opposite parts of the supports 1. In a specific embodiment without limiting the scope of legal protection, the slot stop fixed with a screw to the horizontal crossbar 2 is used as a fastening node 4. Cables 5 are fixed in the fastening nodes 4. The cables 5 are intended for receiving electronic equipment that is negatively affected by the rhythmic oscillations and single impacts occurring in the environment, or for placing shelves for said electronic equipment. In this case, the electronic equipment or the shelves for its placement are attached to individual cables 5 or to the cables 5 stretched between the fastening nodes 4 using loops, pins, hooks and other elements. The cables 5 are elastic materials in the form of belts, ropes, cords, strands or combinations thereof. In a specific embodiment without limiting the scope of legal protection, a rope with a stretch coefficient of 3-5% is used as a cable 5. The cables 5 are fixed on the fastening nodes 4 opposite each other, the length of which can be adjusted.

[0018] The rack is assembled as follows. The frame is made of a support 1 with horizontal crossbars 2 or from at least two supports 1 with horizontal crossbars 2. If there are stops 3, they are fixed to the bottom part of the support 1. When the frame is made from the at least two supports 1, at least two fastening nodes 4 are installed on the horizontal crossbars 2 or on the support 1 of the top part. The cables 5 are fixed in the fastening nodes 4 or one end of each cable 5 is fixed in the fastening nodes 4 and the other end is fixed on the electronic equipment or on the shelf for placement using loops, pins, hooks and other elements. The vibration energy from the environment is absorbed by the cables 5. The vibration isolation is provided by the shock-absorbing effect of the inertial forces of the electronic equipment freely suspended on the cables 5 and the tensile coefficient of the cables 5.

[0019] Industrial applicability

[0020] A rack for mounting electronic devices subjected to negative effects of rhythmic oscillations and single impacts generated 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 force balance. It consists of horizontal elements supported by vertical elements called frames. Cables 5 are positioned at an angle to the horizontal plane and take part of the load, transferring it to the frames. The operating principle of the cable support structure is that the cables 5 will take up rhythmic oscillations and single impacts that occur in the environment. These forces are distributed along the length of the cables 5. The design of the claimed invention provides the ability to fix the units at any height required by the user. This advantage can be used due to the absence of rigidly mounted shelves. This design advantage allows a significant improvement in the ventilation mode and temperature balance of the operating units of electronic devices. The placement height between the units in the rack should be based only on whether it is sufficient to ensure the required convection for thermal balance. Without rigidly mounted shelves, this will allow the most compact placement of the units of electronic devices. The purpose of the invention is to eliminate the rigid mechanical connection of the rack to the electronic devices, through which vibrations and oscillations from the surrounding space in the frequency range that has a negative impact on the quality of operation of each device can reach the electronic devices. This can be achieved by using freely suspended elastic cables 5 to suspend each unit on the rack frame. The small mass, freely suspended elastic cables 5 compared to the mass of the cables 100% structurally exclude the possibility of transmitting external vibrations, resonances and acoustic oscillations in any plane to the devices with a large mass. Due to the freely suspended elastic cables 5, the mass of this unit, which is not rigidly connected to the rest of the system through its own leg (support), will allow the suspended unit of the electronic device to use inertial forces and the force of the Earth's gravity to stabilize its state, which will provide it with a stable state of rest and, accordingly, ensure the highest level of audio-video signal quality specified by the manufacturer. Even if the rack at the location where the cables 5 are fastened to the rack will exert an impact on the cables 5 in the form of vibrations, resonances and acoustic oscillations in any plane, then this will occur relative to the stationary suspended unit of the electronic device.
