  • This invention relates to the field of isolators and, in particular, to a light weight, low profile isolator for sensitive electronic equipment which provides superior shock and vibration protection.
  • Isolators for protecting a mounted structure from shock or vibration forces exerted by another structure are well known and have been used in many industrial and military applications.
  • One class of isolators uses arched flexural elements arranged in a bar-shaped pattern to provide different spring characteristic responses to shock and vibration forces along longitudinal and transverse directions, as shown in U.S. Patent Nos. 4,190,227 and 4,783,038, or in a circular shaped pattern to provide a spring characteristic response alleged to be more uniform and move independent of the direction of origin of the shock and vibration forces, as shown in U.S. Patent No. 5,149,066.
  • a shock and vibration isolator for isolating one or more sensitive elements from a support structure in which frame means having a plurality of corners supports such elements and a plurality of isolator means are coupled to the frame means at the corners and to the support structure, the isolator means including a plurality of arched, individual, flexural support elements configured in an arc opening into the corners.
  • the support elements are configured in a semicircle and the isolator means are grouped into opposing pairs.
  • a damping cushion is contained within and extends from the isolator means to provide additional shock isolation for the frame means.
  • the support elements are coupled directly to the sensitive element and the support structure at preselected locations and are configured in an arc opening generally towards the center of gravity of the element.

  • a frame 10 having a plurality of vertical sides 12 and a plurality of horizontal members 14.
  • the frame 10 has mounted therein, shown in phantom, a sensitive electronic package 16, such as a CD-ROM, which it is desired to isolate from shock and vibration forces.
  • a sensitive electronic package 16 such as a CD-ROM
  • Positioned in each corner 18 of the frame 10 is an isolator 20 having an arc-shaped base 22 mounted by screws 24 to a support structure 26, an elevated support 28 mounted by screws 30 to one of the horizontal members 14 and a plurality of arched, individual, flexural support elements 32 coupled to the arc-shaped base 22 and the elevated support 28, as shown in greater detail in Figure 2.
  • the support elements 32 may be coupled to the base 22 and the support 26 as described in U.S. Patent No.
  • the support elements 32 are generally formed from a plurality of stainless steel wires wound to form a stranded rope, while the base 22 and the elevated support are generally formed from aluminum.
  • each arc-shaped base 22 and its corresponding support elements 32 which are shown having a semicircular configuration, is positioned so that the open portion 34 faces into a corner 18 of the frame 10 and is faced by an opposing base 22 and corresponding support elements 32 facing into an opposing corner 18.
  • This arrangement has several distinct advantages over the use of the above-cited circular isolator. First, it allows the corners of the frame 10 to be open so that electronic packages carefully occupy the frame 10 and not interfere with any of the support elements 32.

  • the open nature of the arc-shaped base 22 also permits the containment therein and the extension therefrom of a clamping cushion 36 to isolate the elevated support 28 and the sides 12 if the shock forces cause the frame 10 to bottom out despite the spring action of the support elements 32 of the isolator 20.

  • isolator 20 is shown positioned between the sensitive electronic package 16 and the support structure 24 and consists of a plurality of arched, individual flexural support elements 22' coupled directly, as by welding, to the package 16 and the support structure 24 and arranged in an arc-shaped configuration 38 with the open portion 40 of the configuration 38 facing generally toward the center of gravity (C.G.) of the package 16.

  • the number and position of the isolators 20' on the package 16 can be varied depending upon the size and configuration of the package 16 and the direction of the shock and vibration forces, as can the precise shape of the arc-shaped configuration 38, the number and placement of the support elements 22' thereon, and the general orientation of the open portion 40 toward the center of gravity.
  • a damping cushion 36' may be placed within the arc-shaped configuration and extending therefrom to afford further shock damping if the shock forces cause the package 16 and the support structure to bottom out despite the spring action of the support elements 22' of the isolators 20' .

Abstract

L'invention concerne un isolateur contre les chocs et les vibrations un ou plusieurs éléments sensibles (16) d'une structure de support (26), dans lequel un cadre (10) ayant une pluralité de coins (18) supporte ces éléments et où une pluralité de moyens isolants (20) sont couplés au cadre (10) aux coins (18) et à la structure de support (26), les moyens isolants (20) comprenant une pluralité d'éléments de support individuels courbés (32) fonctionnant en flexion et disposés en un arc s'ouvrant d'une manières générale vers les coins. Dans une forme d'exécution particulière, les éléments de support (32) ont une configuration de demi-cercle et les moyens isolants (20) sont groupés en paires opposées. Un coussin d'amortissement (36) est contenu dans un moyen isolant (20) et s'étend à partir de celui-ci pour augmenter encore l'isolation du cadre (10) contre les chocs. Dans une seconde forme d'exécution, les éléments de support (22) sont couplés directement à l'élément sensible (16) et à la structure de support (26) à des emplacements présélectionnés, et ils sont disposés en un arc s'ouvrant d'une manière générale vers le centre de gravité de l'élément sensible (16).
