Serpentine structure for a turnstile

In a turnstile of the type which includes a stationary section which defines a plane and a movable section, with the movable section comprised of at least one wing which also defines a plane, with the plane of each wing of the movable section overlapping the plane of the stationary section when each wing approaches the stationary section, with both the stationary section and the wings of the movable section comprising several horizontal structures with spaces between the horizontal structures, and with the horizontal structures of each wing located so that they pass through the spaces of the stationary section as the wing is moved past the stationary section, the improvement comprising:

• the horizontal structures of the stationary section and the horizontal structures of each wing of the movable section comprising loops formed with horizontal segments and curved sections joining horizontal segments which are vertically displaced from each other.
