  • Patent number: 4731918
    Abstract: A corner protector for a tabletop or the like includes a rigid protective body having a platen portion adapted to be received by a recessed region of a tabletop corner and a flange portion which extends generally to one side of the platen portion so as to depend generally downwardly over the tabletop edges at the tabletop corner when the protective body is operatively positioned upon the tabletop. The platen portion defines a plurality of countersunk apertures for the purpose of fixedly securing the protective body to the table with headed fasteners. Each countersunk apertures are sized to accept the head of a flat-headed fastener so that when the protective body is operatively attached to the table corner with the fasteners, the heads of the fasteners do not protrude above the platen portion. The shape of the platen portion is such that the conforming of the shape of the tabletop corner to the shape of a corner of the protective body intended to overlie the table corner is facilitated.
