WIPO Patent Application WO/2012/024928
Kind Code:
A1
Abstract:
Disclosed are a wallboard for an elevator car and a car wall composed of the wallboard. The wallboard includes a rectangular panel (1). Right-angled hems on two sides of the rectangular panel (1) along the widthwise direction form sidewalls (2), and right-angled hems on two ends of the rectangular panel (1) along the lengthwise direction form sealing heads (3). Two strengthening ribs (4) fastened to the surface of the rectangular panel are connected between the sealing heads (3). An outer hem (2-1 ') is arranged on one sidewall at the edge thereof away from the rectangular panel (1), and an inner hem (2-1) is arranged on the other sidewall at the edge thereof away from the rectangular panel (1). Reliable sealing structure between adjacent wallboards is therefore formed. The inner and outer hems structure also helps improving rigidity of the wallboard and linearity of the sidewalls, which consequently reduces effectively noises and vibrations caused by the car wall during high-speed operation of the elevator.
