FIELD: construction.SUBSTANCE: object of the invention is a fence to control passage via a corridor (V), comprising: a base (1), equipped with a driving shaft (10) with a horizontal axis moving a bar (L) in the vertical plane between the lowered closed position and the lifted position, a bed plate (11), which is rigidly connected in rotation with the driving shaft (10), a bar holder, on which the bar (L) is fixed, at the same time the specified bar holder is installed as capable of rotation on the bed plate (11), and the rotary axis (120) of the specified bar holder is oriented so that the bar (L) may move between the working position and the open lifted position, when it is under horizontal effect, at the same time in the lowered lifted position and during movement between the lowered closed position and the lifted open position the bar (L) enters in contact with a closing cam (C), made so that it makes the bar move around the rotary axis (120) into the working position.EFFECT: improved design.10 cl, 9 dwg |
