Abstract
A screen retention system is provided for installing screen covers over large openings having polygonal frames comprising a plurality of mounting strips attached to a frame, each mounting strip having a plurality of posts. Each post has a substantial girth and has an enlarged head formed at its tip, the underside of the head forming a catch substantially around the entire underside. Screen material is mounted over the posts and the heads retain the screen thereon and therefore resist large lateral forces exerted by tension in the screen. A closure loop strip entangles the post heads to retain the loop strip thereon.
Claims10
A system comprising:
- a) a frame about at least the periphery of an opening;
- b) a covering material having a periphery which overlaps the frame, at least the periphery of which is formed of a screen material which has a multiplicity of apertures formed therein;
- c) a multiplicity of posts projecting upwardly from a mounting strip affixed to the frame, the number of posts being substantially the same as the number of apertures in the screen material, each post having a girth which is substantial, and an enlarged head having an underside forming a circumferential catch;
- and
- d) a plurality of removable capping strips for installation about the periphery of the covering material, the capping strips having a plurality of loops formed thereon so that when the multiplicity of apertures of the screen material are installed over the multiplicity of post heads and the capping strips are installed with the loops engaging the post heads, then the capping strip securely retains the screen material and cover to the mounting strip whereby the cover can be retained to the frame.
A removable covering comprising:
- a) covering material having a periphery which can overlap a frame and wherein at least the periphery is formed of a screen material which has a multiplicity of apertures formed therein;
- b) mounting strips adapted for affixing to said frame, the strip having a multiplicity of posts projecting upwardly therefrom a mounting strip, the number of posts being substantially the same as the number of apertures in the screen material, each post having a girth which is substantial, and an enlarged head having an underside forming a circumferential catch;
- and
- c) capping strips for installation about the periphery of the covering material, the capping strips having a plurality of loops formed thereon so that when the multiplicity of apertures of the screen material are installed over the multiplicity of post heads, and the loops engage the post heads, the capping strip securely retains the screen material and cover to the mounting strip whereby the cover can be retained to said frame.
