Abstract
A latch for a section door wherein near the hinges located between the door elements there are provided, at each end of the elements, small rolling wheels which turn on horizontal pivots and slide within side guide bars having a vertical branch, an upper horizontal branch, and a curved connection branch located between the vertical and horizontal branches; the latch is located sideways and is intended for engaging, in its active position, in an opening provided in one of the side guide bars. The side latch is located coaxially with one of the small wheels intended to slide within the side guide bars of the section door. Preferably, the small wheel coaxial to the latch is mounted on a hollow pivot, and the latch is guided to slide within the bore of this hollow pivot.
