Abstract

An access control device (1) for blocking or opening a passage (2) for persons or vehicles. The access control device comprises one or two blocking bodies (3, 3′), each arranged on a carrier (4, 4′). Each blocking body (3, 3′) comprises a mechanically reversibly deformable element (5, 5′) which, in a first position, is substantially planar and opens the passage (2) and, in a second position, assumes a curved shape which blocks the passage (2). One or both ends of the deformable element (5, 5′) are connected to an actuator (7). A controller controls the deformable element for transferring them first between the first and second positions. When transferring the deformable element from the first to the second position, either the distance between the ends of the respective blocking body is reduced or, when the ends have a constant distance, the length of the blocking body is increased.

at least one end of each mechanically reversibly deformable element ( 5 , 5 ′) is connected or operatively connected to an actuator ( 7 ) which is connected to the respective carrier ( 4 , 4 ′) and controllable by a controller, and, by the control of the respective actuator ( 7 ), the mechanically reversibly deformable element ( 5 , 5 ′) is transferred from the first position to the second position and vice versa, and
one of:
a distance between the ends of each respective at least one blocking body ( 3 , 3 ′) is reduced so as to transfer the mechanically reversibly deformable element ( 5 , 5 ′) from the first position to the second position, or

The access control device ( 1 ) according to claim 1 , wherein the at least one blocking body ( 3 , 3 ′) comprises two blocking bodies ( 3 , 3 ′), and the respective carriers ( 4 , 4 ′) are arranged on opposite sides of the passage ( 2 ) and are mirror-symmetrical with respect to a central longitudinal axis of the passage ( 2 ).

4. The access control device ( 1 ) according to claim 1 , wherein one end of the respective mechanically reversibly deformable element ( 5 , 5 ′) is respectively connected to an actuator ( 7 ) or by a hinge ( 8 ) to the carrier ( 4 , 4 ′), the other end is connected, in a hinged manner, to one end of a non-elastic element ( 10 ), the other end of which is connected to an actuator, wherein the length of the respective blocking body corresponds to a length of the respective mechanically reversibly deformable element plus a length of the non-elastic element.

5. The access control device ( 1 ) according to claim 1 , wherein the mechanically reversibly deformable element ( 5 , 5 ′) is made of rubber, metal, fiberglass reinforced plastic or laminated plastic and has a torsional rigidity by which a bending of the element, by human force, is impossible.

6. The access control device ( 1 ) according to claim 2 , wherein the surface normal of the respective element ( 5 , 5 ′), designed as a leaf spring, runs parallel or perpendicular to a passage plane in the first position.
