This is a technical solution to the problem of controlling access to spaces for, for example, animals that depend on these spaces for shelter from cold, wind, rain and insects. The invention consists of a Frame in which a Flap is attached, which is made up of a flexible Carrier on which symmetrical horizontal Articulations are arranged on either side. The articulations provide a closure that can be easily opened by animals and completely closes off the opening in the frame when in rest position. This invention meets the requirements for such access control: the requirements of closure, variable opening force, reliability, usability, durability, environmental adaptability, safety and chewing protection.
