Abstract
(EN)
A compressible spring or shock attenuating apparatus is disclosed for axial insertion within an elongated hollow receptacle having a predetermined inner diameter. The compressible spring of the present invention comprises an elastomer body (16) having an outer diameter and a pair of axially spaced ends. A series of substantially equal annular crests (18) are axially disposed relative to each other on the elastomer body (16) between the spaced ends, with a periphery of the crests (18) defining an outer diameter for the elastomer body (16). The elastomer body (16) is specifically configured such that the outer diameter of the elastomer body (16) remains substantially constant even when the ends of the spring are compressed toward each other. According to the present invention, each crest (18) of the elastomer body (16) has a closed annular ring (30) fixed and extending thereabout to promote maintaining the outer diameter of said body substantially constant as the ends move toward each other while defining predetermined outer diameter for the spring. The predetermined outer diameter of the spring is greater than the outer diameter of the elastomer body (16) and is sized to the inner diameter of the receptacle whereby the rings (30) promote axial movements and inhibit snaking movements of said spring within the receptacle.

La présente invention concerne un amortisseur ou un ressort compressible devant être introduit axialement dans un réceptacle oblong creux, présentant un diamètre interne prédéterminé. Ce ressort compressible est constitué d'un corps en élastomère (16) présentant un diamètre externe et une paire d'extrémités axialement espacées. Une série de crêtes annulaires pratiquement égales (18) sont placées axialement les unes par rapport aux autres sur le corps en élastomère (16), entre les extrémités espacés de celui-ci, la périphérie des crêtes (18) formant un diamètre externe pour le corps en élastomère (16). Ce corps en élastomère (16) est spécialement configuré pour que son diamètre externe demeure sensiblement constant même lorsque les extrémités du ressort sont comprimés. Selon cette invention, chaque crête (18) du corps en élastomère (16) présente une bague annulaire fermée (30) fixe s'étendant de façon à faciliter le maintient du diamètre externe de ce corps sensiblement constant à mesure que ses extrémités se rapprochent l'une de l'autre, tout en formant un diamètre externe prédéterminé pour le ressort. Le diamètre externe prédéterminé du ressort est supérieur au diamètre externe du corps en élastomère (16), et il est calibré par rapport au diamètre interne du réceptacle. D'autre part, les anneaux (30) activent les déplacements axiaux et inhibent les déplacements sinueux du ressort dans le réceptacle.
