The present invention relates to an instrument of particular utility for effective and secure stacking of storage rack units.
Simple and cost-effective means for securing the structure and stacking of storage rack units in a storage shelving assembly has long been an interest and concern in the shipping and warehousing industries. The present invention provides an elegant and readily mass-produced bracket instrument and system to easily and economically implement a new solution to strengthen and secure rack systems for home, garage, and warehouse use.
An objective of the present invention is to provide a simple tool comprising a bracket configured in such manner, with a protruding tab that inserts into receiver apertures in the shelving upright support post structures, to easily attach and secure the bracket to the upright and, additionally, to provide a horizontal support for horizontal load-bearing shelving to be placed, and stacked, in connection with the bracket upon the upright shelving rack structure.
Brackets and methods for stacking a storage rack are described herein. The brackets are configured to securely connect a first storage rack unit on top of a second storage rack unit.
The left and right stacking brackets are formed with a substantially L-shaped cross section where a first extension is substantially perpendicular to a second extension. The two extensions are joined at a corner. In this embodiment, the corner is rounded, but the corner may also be at a sharp angle.
On one of the extensions, the bracket comprises one or more tabs. The tabs may be formed via a punching operation in the sheet metal such that the tabs protrude (internally within the extension corner angle) from an aperture in the extension of the bracket. The tabs may be formed at a diagonal angle relative and away from the side edges of the bracket.
The extension also comprises a locking pin aperture. As shown in
The attachment holes are wider towards a top side of the receiver attachment open aperture holes and narrower towards the bottom. This allows the tabs of the stacking brackets to be inserted towards the top of the receiver attachment open aperture holes. When the tabs slide or otherwise move downward in the holes, the tabs move to a locking position where they cannot be removed from the receiver attachment open aperture holes.
To ensure that the stacking brackets do not accidently move upwards into a position where they can be removed, a locking pin is provided that extends through the locking pin aperture of the stacking bracket and through the wider top side of the receiver attachment open aperture holes. This locks the stacking bracket in place because the tabs may not move out of engagement with the receiver attachment open aperture holes.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of this invention. In addition, the various features, elements, and embodiments described herein may be claimed or combined in any combination or arrangement.
This application claims priority to U.S. Provisional Application No. 62/704,259 which was filed on Apr. 30, 2021, the contents of which are hereby incorporated by reference.
