Abstract: A fly screen apparatus having a screen with a handle at an end thereof. The handle has opposite ends received respectively within a pair of runners. The runner has a guide and positioning track formed on an inside surface of the runner. An intermediate rest element is formed in an intermediate position on the side of the runner. The handle has a guide piece supporting a tip which is longitudinally mobile. The tip follows the guide and positioning track so as to be located in various positions within the runners.
Abstract: Header to support one end of a rewind roll and to close off at least one end of the casing, used particularly for fly screens, includes:
a bottom from which, along the perimeter of the side close to the casing, there is a discontinuous border that protrudes, with a number of seats for fitting the corresponding end of the said header; and
a flat, monolithic part formed in the said bottom that protrudes downwards, with holes formed on the surface in order to fasten it to the uprights of an opening;
wherein, in a bottom, there is a central hole with a key-way into which the end of a pin is connected and thus fixed to the part of the header. The end is mushroom shaped and is flexible, and fits into a hollow in the rear part, that is, on the side on the outside of the header.
Abstract: A mechanism for quick hooking and unhooking of a handle, used particularly for fly screens and fly screen assemblies with a chain-operated movement. The invention includes a casing containing a rewind roll, a screen fastened to the rewind roll and a handle, and runners. The handle was a tubular profile with a hooking mechanism on one end. The hooking mechanism of the handle operates in conjunction with a reciprocal holder attached to a lower end of a runner.
Abstract: Assembly for unwinding a protective screen, with a quick-release mechanism for hooking and unhooking the handle used particularly for fly screens, and which includes: at least one holding means at the lower end of one of the runners, with the upper part which is open and which contains a guide path with an inlet, an outlet and an intermediate rest position; at least one hooking means located at the end of the handle, and which includes a guide piece which longitudinally guides a mobile tip. The said tip has a protruding pin on at least one side that fits into the guide-track in holding means; and in which, at the beginning of the said guide path, formed in the inlet of the holding means in correspondence with the lower part of at least one of the runners, there is a deviation towards the lower part which co-operates with a stop point.
