Abstract
A mantrap in which a demarcation in shape of a segment of an arc is provided at one side of a passage. The open side of the demarcation faces the other side of the passage. The demarcation extends, furthermore, along a predetermined angle of circumference and has a barrier element that rotates around a vertical axis positioned approximately in the center of the demarcation and is provided with leaves extending out from the vertical axis of rotation and including equal angles. The leaves have grating rods positioned separately and one above another. A barrier rake extends out from an axis of the barrier element to the other side of the passage, and has grating rods displaced in position from the grating rods in the leaves and one above another. The barrier-rake rods allow unimpeded rotation of the barrier element. The barrier rake, furthermore, is a gate element, and the barrier element is a rotating door with at least two leaves.
