Abstract:
A system for restricting an object from sliding along a substantially horizontal edge formed by a substantially horizontal surface intersecting a substantially vertical surface of a structure, the system comprising a plurality of protection devices attached to the structure with each of the protection devices overlying the substantially horizontal edge and extending along the substantially horizontal surface and the substantially vertical surface, the protection devices being spaced along the substantially horizontal edge at intervals selected to prevent objects from sliding along the edge, each protection device comprising: an obstruction fixture having a body possessing a circular cross section attached to a mounting bracket which is secured to the vertical and horizontal surfaces of the structure with the body of the obstruction fixture positioned astride the edge so that the object sliding along the edge will contact the body of the obstruction fixture; with each protection device extending along the substantially horizontal surface in a first direction perpendicular to the substantially vertical surface a distance that is less than half of the width of the substantially horizontal surface in the first direction and extending along the substantially vertical surface in a second direction perpendicular to the substantially horizontal surface a distance that is less than half of the height of the substantially vertical surface in the second direction.
