US Patent 7506852 Shelving support bracket

A shelving bracket for supporting an end of a shelf is adapted to be attachable at any location along the length of a heightwise extending pole. The bracket is adapted to bear against a side face of a pole and includes at least two guide surfaces engageable with front and rear faces of the pole to define the angle of orientation of the bracket and to maintain the bracket at that angle. The bracket is secured rigidly to the pole by a fastener. A second pole is provided with a similar shelf bracket. Each of the shelf brackets has a shelf-supporting ledge adapted to support an end of a shelf that spans between the poles.
