Patent

CA 2585130

A device for forming a seal includes upper and lower seal members, and a slider, wherein mating surfaces of the seal members interlock. In at least one embodiment, a lifting rib and closure bar on the slider cooperate with a lifting wing and closure bar groove on the upper and lower seal members, respectively. By moving the slider in one direction, the lifting rib lifts the upper seal member from the lower seal member. Moving the slider in the opposite direction causes the upper and lower seal members to interlock. In another embodiment, a slider has an intermediate lateral member connected on one side the slider top, and connected on the other side to the slider bottom. A breakaway sealing device is also provided, allowing a person to break the closed seal. A beginning stop block is also provided that includes a means for securing the upper seal member.

Dispositif de réalisation de joints, qui comprend un élément supérieur et un élément inférieur de joint, et un coulisseau qui permet d'assujettir l'une à l'autre les surfaces correspondantes des éléments de joint. Dans au moins un mode de réalisation, on trouve une nervure de levage et une barre de fermeture sur les éléments de joint supérieur et inférieur, respectivement. Lorsque l'on déplace la glissière dans une direction, la nervure de levage soulève l'élément de joint supérieur en l'écartant de l'élément de joint inférieur. Le déplacement de la glissière dans la direction opposée a pour effet d'assujettir les éléments de joint supérieur et inférieur l'un à l'autre. Dans un autre mode de réalisation, la glissière comporte un élément latéral intermédiaire relié sur un côté au haut de la glissière, et sur l'autre côté au bas de la glissière. L'invention concerne également un dispositif d'étanchéité à ouverture d'urgence permettant à une personne de rompre le joint fermé. On trouve également un bloc de butée de départ permettant de fixer l'élément de joint supérieur.
