Patent ID: 7510056

Claim:
An elevator car roof railing with collapsible sides hinged on a supporting frame on the car roof, comprising: two sides that can be folded inwards as an accordion in at least two parts, perpendicular to a landing door opening of the elevator shaft and hinged to said supporting frame near a bottom part of the sides; an upper rear side bar connected near a rear upper end of each of said two sides; an actuation handle with a length approximately equal to a depth of the elevator car and hinged near said supporting frame near a rear middle part thereof, perpendicular to said landing door opening, wherein the handle is connected at least by a rod hinged in a median plane to the upper rear side bar, and by a lateral rod with a terminal ball-and-socket joint to the rear part of each of the two sides, wherein said handle is configured to be lifted through the landing door opening from a lower, substantially horizontal position in which the railing is collapsed, to a locked upper position that is substantially vertical, pulling along the two sides at the same time to erect them vertically and form a third rear side of the railing with rear connecting rods of said two sides and the upper rear side bar on which it is applied and locked, and is configured to be lowered from the upper position to the lower position such that displacement of the handle causes simultaneous folding of the two sides and collapse of the railing to a small height above the car roof.
