#CMT# #/CMT# The arrangement (1) has a door (8) linked at a frame (2) by a drag hinge (10) whose pivotal axis is arranged vertical to a door plane. The drag hinge is arranged at a bottom region of the door. The door covers a portion of a door opening (6) in a closed state. The door has a parabolic or elliptic curved frame part (12) whose end sections are connected with each other by a door frame-side frame strut (16) which is arranged parallel to a neighboring door post (14). A guide bar (24) is fed from the frame part and extended upward along a guide (28). #CMT#USE : #/CMT# Door arrangement for use as an access door arrangement to enable an animal i.e. cow, to enter into or exit from a region of animal husbandry i.e. milking parlor (claimed). #CMT#ADVANTAGE : #/CMT# The door is linked at the frame by the drag hinge whose pivotal axis is arranged vertical to the door plane, so that risk of injury to the cow is reduced.
