摘要

Constructive disposition applied in staircase milling. This utility model patent refers to a new provision constructive applied in ladder pantographic designed with the objective of ensuring easy handling to enable achieving ascents, descents and go back to the position parqueada.The present invention consists basically of a base (1) provided with a fixed step (2) and (3); a chamber systems composed of two contrabalanu00e7os tubular chassis (4); two rods with limiters (5) with step mobile base (6) and (7) intermediu00e1nos steps mobile and fixed lateralment And the tubular chassis (4),To the rods (5) and the two commu00e3os with protection central (8) articulated and connected to the base (1). The step (6) has a support (9) fixed on it. The step mobile intermediary (7) has front (10) articulated through articulated side arms (11) and the rear part (12) fixed (DET (a).The drive of the equipment is done by means of a pedal composed of spring and lock (13) is located to the right of the fixed step (2) of the base (1). Optionally, you can be adopted even a guard body (14), fixed to the front rails (8) and a system of audible alarm (not shown) in order to signal when the same is not parqueada.
