CA 2493241

A tube bender, comprising a mandrel, a forming member connected to the mandrel for coaction with the mandrel to effectuate at least 180 degree bending of a tube wherein the forming member has at least two bending positions defined thereon, a handle pivotally connected to the forming member, a release member movable relative to the handle wherein the release member is associated with the handle, and engagement means for securing the release member in a locked position relative to the forming member when the handle is selectively moved to any of one the at least two bending positions thereby preventing relative movement between the handle and the forming member. The release member enables an operator to move the release member to an unlocked position to permit such operator to move the handle relative to the forming member between the at least two bending positions.

L'invention concerne un dispositif de cintrage de tube comprenant un mandrin; un élément de formage relié au mandrin destiné à coagir celui-ci afin d'effectuer au moins un cintrage de tube à 180 degrés, l'élément de formage présentant au moins deux positions de cintrage définies sur celui-ci; une poignée reliée de manière pivotante à l'élément de formage; un élément de libération mobile par rapport à la poignée, ledit élément de libération étant associé à ladite poignée; et un organe de coopération destiné à fixer l'élément de libération en position verrouillée par rapport à l'élément de formage lorsque la poignée est déplacée sélectivement vers l'une quelconque des deux positions de cintrage, ce qui empêche un déplacement relatif entre la poignée et l'élément de formage. L'élément de libération permet à un opérateur de déplacer l'élément de libération vers une position déverrouillée, ce qui permet audit opérateur de déplacer la poignée par rapport à l'élément de formage entre les deux positons de cintrage.
