<p>The invention relates to a gate for persons for cyclically opening a passage having at least one blocking element connected to a moveable carrier element and moveable from a blocking position blocking passage at a blocking site into a passage position allowing passage, having a blocking device for blocking the movement of the carrier element comprising at least one bar (18, 20) contacting a working surface (16) of the carrier element at least one contact point in a blockage position, the bar (18, 20) being moveable from the blockage position into an open position, the movement thereof at the contact point taking place in a first direction of motion, and the working surface (16) moving in a second direction of motion at the contact point when the carrier element moves. According to the invention, an angleβbetween the first direction of motion and a tangent at the line of intersection of the tangential surface with the working surface (16) at the contact point is included in the plane passing through the first and the second directions of motion, the tangent thereof (tanβ) being described by 5/9μ≰tanβ≰9/5μ,μbeing the coefficient of static friction between the bar (18, 20) and the working surface (16).</p> |
