Abstract
A knock-down support structure for shelving units having upright hollow posts with internal perpendicular channels and connecting horizontal stringers with bent ends inserted in said channels. The bent ends have struck-out tabs that are held in keyhole slots in the posts. The structure has a locking means on the stringers for locking the respective stringer to the adjacent post.
Claims9
A knock-down support structure for shelving units comprising an upright hollow post having a first channel and a second channel extending substantially perpendicular to said first channel and communication therewith, said post having a plurality of keyhole slots in spaced superposed relationship adjacent to said second channel, a connecting stringer having at least one extreme end being provided with a flange extending substantially perpendicular to the plane of said stringer and provided with a tab element on the surface of said flange adjacent to said keyhole slots, and a part of said stringer adjacent to said flange being inserted within said first channel while said tab element is in said second channel and latched in a selected keyhole slot.
A knock-down support structure for shelving units comprising an upright T-shaped, channelled hollow post wherein the bottom channel of said T is open at the bottom, said post having plurality of keyhole slots in the top channel of said T disposed in spaced, superposed relationship, a connecting stringer having at least one extreme end being provided with a flange extending substantially perpendicular to the plane of said stringer and provided with a tab element on the surface of said flange adjacent to said keyhole slots, a part of said stringer adjacent ot said flange being inserted through said bottom channel, said tab element being in said top channel and latched in a selected keyhole slot, and locking means on said part of the stringer for locking the respective stringer to the bottom channel of said T-shaped hollow post.
A knock-down support structure for shelving units comprising an upright inverted L-shaped channelled hollow post or standard wherein one leg of said post is open at one end, said post having a plurality of keyhole slots in the other leg of said post disposed in spaced, superposed in relationship, a connecting stringer adapted to be mounted perpendicular to said post and having at least one extreme end which is provided with a flange extending substantially perpendicular to the plane of said stringer and having a tab element on the surface of said flange adjacent to said keyhole slots, a part of said stringer adjacent to said flange being inserted through the open end of said leg, said tab element being in the other leg of said post and latched in a selected keyhole slot, and locking means on said stringer for locking the respective stringer to said one leg of said post.
A method of assemblying a support structure for shelving units from interchangeable parts comprising a plurality of spaced upright hollow posts having a pair of channels extending perpendicular to each other, inserting a plurality of said stringers having end parts within said channels, said end parts of said stringers being provided with tabs for insertion in keyhole slots in said posts, and providing a locking means on said stringers in the form of a rotatable cam lock for latching said stringers rigidly to said upright posts.
