ABSTRACT:
A flexible duster head holder includes a stiffener over which a conventional duster head is placed. The stiffener may be bent to conform to the shape of a non-flat surface to be dusted. The stiffener consists of a bendable metal wire core which is sufficiently rigid to hold the shape to which it is bent until being bent to a different shape. Surrounding the core is a resilient vinyl sheath or cover which limits the sharpness of any bend that can be imparted to the stiffener, thereby reducing the likelihood that the wire core will break. Two different methods are described for attaching the stiffener to a clamp assembly. In one, the stiffener is inserted into passages in a mounting block and glued in place; in the other, the stiffener extends all the way through passages in the mounting block, and exposed ends of the wire core are folded over into a U-shape such that the stiffener cannot be withdrawn from the mounting block when the mounting block is secured to the clamp assembly by being received between the arms of a clevis and riveted in place.
