ABSTRACT OF THE DISCLOSURE An overhead garage or the like door 5 has a door panel or leaf 11 held by a pair of spring-loaded levers In the closed state, the bottom edge section of the panel is guided by two guiding rollers 12 on the guide surfaces 14 of the door frame. The levers 10 are each pivotably secured with their one end at mid-length of the respective side edge of the door panel. The other end of each lever 10 is pivoted near the upper end of the generally vertically arranged guide surface of the door plane. One end 20 of a first cable 22 is installed in the area of one of the guiding rollers 12. This first cable 22 has a first section or component portion 23 parallel to the guide surface 14, extending upwards to an upper corner 27 of the door frame 7, then deflects over a generally right angle to form a second, horizontal section or component portion 24 and then is guided again to a third, generally vertical section down to the bottom end of the second guide surface 14, and from there, after another turn at approximately 180°, it extends upwards into a fourth section or component portion 26. The second end of the first cable 22 is then secured to the other guiding roller. Another cable similarly extends from the other roller 12 to the first mentioned roller 12. The invention improves the accuracy of the guiding of the door panel and prevents undesired jamming thereof.
