Abstract:
A fastener comprising a body, a screw, a cross bar, and a spring;said body including a head and a sleeve wall extending from said head and centered on an axis of said fastener; said head of said body having a surface that is engagable with a structure to block inward movement of said body relative to said structure; said sleeve wall having an outer end portion connected with said head of said body, said sleeve wall having a central portion extending from said outer end portion, said central portion having an axially extending central opening for receiving said screw therein, said sleeve wall having an inner end portion through which said central opening extends and which has an inner terminal end of said sleeve wall, said central portion of said sleeve wall having diametrically opposed slots communicating with said central opening, said central portion of said sleeve wall having slot end surfaces that define inner ends of said slots spaced axially from said inner terminal end of said sleeve wall, said central portion of said sleeve wall having slot end surfaces that define outer ends of said slots spaced axially from said head; said screw being insertable into said body, said screw having a head for limiting inward movement of said screw into said body, said screw having a threaded shank extending through said central opening in said sleeve wall to a location disposed radially inward of said slots; said cross bar having a central portion and first and second opposite end portions, said central portion of said cross bar having a threaded opening receiving said threaded shank of said screw, said first and second end portions of said cross bar projecting radially outward from said central opening in said sleeve wall through said slots in said sleeve wall, said sleeve wall having slot side surfaces engagable by said cross bar end portions to block rotation of said cross bar relative to said sleeve wall; said screw being rotatable in said body and in said cross bar to effect axial movement of said cross bar in a direction toward said head of said screw and into a position in abutting engagement with the structure to limit outward movement of said cross bar and said screw relative to the structure; and said spring being disposed in said body, said spring being smaller in diameter than said slots in said sleeve wall, said spring being insertable laterally into said sleeve through one of said slots in said sleeve wall.
