Ninety degree turn fastener

Abstract

The present invention relates to a ninety degree turn fastener composed of two parts made of resistant materials, either metal or other, which meet the technical requirements to allow their machining in order that they may fulfill their purpose; once the parts have been machined and by the nature of the functions they perform within the fastener, we shall call them females and male, with the same outline shapes to ensure that they match; the face of the female part in its central area is made up of a raised flat surface with a concave rear side to accommodate the wings of the male part, this being surrounded by another dish-shaped plane, which constitutes the base for attachment of the fastener; the center of the front face has a rectangular opening, with a width appropriate for carrying out its purpose, and approximately three times as long as it is wide. The outer attachment plate has a groove with several holes distributed along it, and a number of clamps for attachment, whether it be by sewing or by any other means; the male part is flat on its rear side; from the center of the face there protrudes a round nucleous measuring the same as the width of the opening in the female part, which opening matches the central nucleous ended in a T shape, whose wings are sufficiently separated from the base plate as to clear the side faces of the female opening when turning through 90 degrees in order to fasten; the length is equal to that of the female opening; the means of attachment of the male part to its corresponding piece of garment are the same as the means of attachment of the female part to its corresponding piece.
