ABSTRACT:
A retainer assembly for securing a sheet-like material to a wall comprising an elongated stud having an inner end welded to the wall and extending outwardly therefrom so as to be perpendicular to the wall, the stud having a pointed outer end whereby the sheet-like material can be impaled thereon and positioned so as to be adjacent the wall, the stud being provided with a longitudinal slit extending from the outer pointed end to a location adjacent the inner end so as to form a pair of longitudinal fingers, the stud being bent adjacent the inner end whereby the fingers are laterally offset from each other, the fingers being provided with alternate outwardly extending teeth and recessed notches along the longitudinal sides of the fingers opposite from the slit, and a retainer plate provided with a central opening therein such that the pointed end of the stud can be inserted through the opening to permit the plate to be slidably received on the stud, the opening in the plate being approximately equal to the distance between the notch on one finger and an opposed notch on the other finger, whereby, when the plate is urged in a direction from the pointed end of the stud towards the inner end thereof, the fingers will move in a scissors fashion as the plate passes over the teeth on the fingers, and whereby, when the plate comes to rest in a desired position in a pair of opposed notches on the fingers, the fingers will spring back towards their original disposition to lock the plate in the desired position.
