  • L-shaped upper segment 32 has a vertical portion, where anchor bolt hole 32a is formed, and a horizontal portion, where screw hole 32b is formed.
  • Lower segment 34 is fixed to plate
  • First supporting piece 36 having a screw hole is disposed under extended portions 34b of lower segment
  • upper segment 32 is fixed to lower segment 34.
  • vertical portion of upper segment 32 is fixed to the wall of the hoistway by tightening an anchor bolt to the wall of the hoistway through anchor bolt hole 32a.

Abstract

Cette invention concerne un ensemble porte palière pour système d'ascenseur, dans lequel la déformation d'un panneau de porte peut être limitée sans éléments de renforcement supplémentaires. Cet ensemble porte palière comprend un panneau de porte, un montant de jambage et au moins une fixation à crochet et étrier destiné à verrouiller le panneau de porte contre le montant de jambage, lorsque le panneau de porte est en position fermée, pour empêcher le panneau de porte de s'éloigner du montant de jambage et de se rapprocher du puits. Le crochet est monté sur le panneau de porte et l'étrier est monté sur le montant de jambage ou inversement. Lorsque le panneau de porte est en position fermée, le crochet s'aligne sur l'étrier et se fixe à lui.
