Abstract:

A drawer of the sort used in cabinets, desks, files and the like is supported for sliding movement by a single self-aligning center rail. The rail is mounted to the cabinet frame preferably above the drawer, extending from front to back. It is supported at its forward end by a bracket in fixed position and at the rear end by a cup-shaped receptacle allowing limited lateral movement of the rail end. A bifurcated drawer guide is attached at its lower end to the back wall of the drawer and at its upper end slidably engages the rail. The rail is tubular for the major portion thereof while the forward end is flattened to provide a partial stop action for the drawer and also provide means for the drawer to be fully removed. Low friction guide plates are mounted about the drawer opening for quiet, easy movement thereof.

Paul M. MacDonald - Scituate MA

Assignee:

PX Industries, Inc. - Rockland MA

International Classification:

B65D 6300

US Classification:

24 16R

Abstract:

A protective corner shield for use with strap-bound stacks of cartons or the like is provided to prevent a highly tensioned strap from damaging the corners of the stack. The shield is formed with two flat legs substantially perpendicular to one another having parallel spaced ribs on their outer surfaces defining a shallow channel to receive and position the strap. One of the legs is formed on its inner face with a lip extending in spaced parallel relation to the other leg by a distance corresponding to the thickness of one of the stacked cartons. The lip when slipped between two cartons in the stack serves to hold the corner shield in position before, during and after the installation of the strap.
