Title
(EN) PASSENGER CONVEYOR STEP HAVING AN ACOUSTIC BARRIER
(FR) MARCHE D'ESCALIER MECANIQUE A BARRIERE ACOUSTIQUE
Abstract
(EN) An escalator step (12) includes a sound barrier material (40) covering over at least a portion of an inner surface (42) of a tread portion (30) and an inner surface (44) of a riser portion (32). In one example, the sound barrier material (40) comprises a sheet of vinyl. The sound barrier material (40) reduces noise radiation from the step (12) toward a cavity (26) within a passenger conveyor support structure (20) and reduces noise emanations from the cavity (26) through the steps (12). Several embodiments for securing the sound barrier material (40) in place are disclosed.
(FR) La présente invention concerne une marche d'escalier mécanique garnie d'un matériau barrière sonore (40) sur une partie au moins d'une surface intérieure (42) de la tablette (30) et d'une surface intérieure (44) de la contremarche (32). Dans un exemple, le matériau barrière sonore (40) comprend une feuille de vinyle. Le matériau barrière sonore (40) réduit le bruit rayonné par la marche (12) vers une cavité (26) à l'intérieur d'une structure support de l'escalier mécanique (20) et réduit les dégagements sonores de la cavité (26) au travers des marches (12). L'invention concerne plusieurs modes de réalisation de fixation à demeure du matériau barrière sonore (40).
