2. Description of Related Art
The making of wood shelves and draws is an art that in times past was common knowledge to most people. However, through the last century, people have become more urbanized and less accustom with the ways of elementary carpentry. However, the need for shelving and drawers to maximize storage space has remained, but the skill to make them has not. Today, to fill the need for home, closet and garage shelving and drawers, many designers and manufactures have devised shelf and drawer systems. These systems vary from permanent structures to removable units to adjustable units and combinations thereof. In addition, the material used in their construction varies from wood, metal, plastic and a combination of the three. In the case of wood shelf and drawer systems, solid woods, plywood and composition wood are commonly used. The conventional wood shelving and drawer systems have inherent problems. One such problem is the sacrifice of lead bearing capacity for ease of assembly and adjustability in the placement of the shelves and drawers. Another problem with conventional systems is the eventual loss of structural integrity of the attachment mechanism, or the wall structure of the system.
It is an object of the present invention to overcome the drawbacks and shortcomings of conventional wood shelf and drawer systems while allowing the versatility of a quick adjustability of shelves and drawers to meet the changing demands of a user. Particularly, conventional wood shelf and drawer systems do not provide a means of quick adjustable assembly and high load bearing capacity. Many conventional wood shelf systems incorporate a hole in a support wall with a dowel or peg fitted into the hole to support a shelf. The loading and moments caused by shelves on the above mentioned support devices will cause the supporting walls to fatigue and eventually fail at the top of the hole. The design of conventional support devices converts loads into moments. These moments place a shear force on materials with great capacity to support compression forces, but with limited ability to withstand shear forces. The present invention places loads in compression on a supporting wall and on the shelf itself while minimizing moments and shear forces. Prior systems and devices sacrifice load bearing capacity for quick adjustable assembly or they sacrifice the quick adjustable assembly for more load bearing capacity. Either way, conventional systems are limited in their versatility. The present invention provides a system and devices that allow a user to quickly assemble and adjust both shelves and drawers without sacrificing load bearing capacity.
Additionally, conventional shelf systems have no means to restrain a shelf in position without the use of fasteners. An unfastened shelf can slide off its shelf supports creating an unsafe situation. The present invention incorporates the use of shelf brackets and notches in the shelves to lock the shelves in place without the need of fasteners.
Further, an added benefit of the self-locking shelves provided by this present invention, is that an unfastened shelf can now have a span-wise bracket. On conventional systems with shelves that can slide off the shelf support, a span-wise support bracket may not support the shelf because the shelf may not be positioned in the proper location. The present invention overcomes this by the added benefit of the self-locking shelves. The self-locking shelves allows for a span-wise bracket to be installed without the use of fasteners.
Another benefit to a user is that the present invention provides to a user is that no tools are required for the removal or adjusting of the shelves and drawers. Additionally, this invention incorporates a support bracket to adapt other devices for use within this invention.
This invention overcomes the drawbacks and shortcomings of the prior art conventional devices and systems.
