Description

FIELD OF THE INVENTION

The present invention relates to tray assembly slidably mounted within a cabinet and provided with an expandable assembly and a plurality of tines to support items therein.

BACKGROUND OF THE INVENTION

Today's modern kitchens are provided with an abundance of storage space, but none are used more than the kitchen cabinet. These cabinets are used to store dinnerware such as bowls, plates, and the like, in a stacked format. Additionally, they are used to store cookware such as pots, pans, lids, and the like as well. Unfortunately, this stacked arrangement often means that several items must be removed until the user can get at the one he or she needs. This not only a time-consuming process, but also exposes other pieces of dinnerware or cookware to possible damage from chipping or even breaking. Accordingly, there exists a need for a means by which desired dinnerware and cookware items can be easily removed from a kitchen cabinet, without impacting other items, and without exposing them to possible chipping or damage. The development of the expandable cabinet tray fulfills this need.

The expandable cabinet tray is a storage apparatus for kitchen cabinets that holds various dinnerware and cookware items. The invention is intended to increase usability of the kitchen cabinets as well as prevent damage to the stored items. The invention is comprised of an overall stainless steel frame which fits into the upper wall section of a kitchen cabinet. It is provided with an adjustment mechanism to securely install the invention in place. The frame provides an inner moving mechanism which extends in and out of the cabinet area. In turn, this extension portion includes adjustable dividers for storing each individual piece of dinnerware, such as bowls, plates, cups, or the like. It can also be used to store cookware such as pots, pans, lids, and similar products. As such, at no time does any piece of dinnerware or cookware touch another item. This makes it very easy to remove one item, without having to move other items for access. Additionally, it prevents damage to the item by eliminating the possibility of chipping or breaking. It is envisioned that the present invention could be easily installed in almost any type of kitchen cabinet with a minimal amount of tools, and could be removed at a later date, without leaving any telltale marks behind.

SUMMARY OF THE INVENTION

The expandable cabinet tray is designed with utility and convenience in mind, and is easy to install and use. The tray consists of a primary base plate and an expanding base plate, which are attached to the inside of the cabinets with adhesive pads, such as mastic. This way, no damage to the cabinet would exist. However, if desired, permanent installation could be achieved by using threaded fastening mechanisms.

Base assemblies are preferably stainless steel, and adhesive pads would be placed on the underside of the horizontal portion of each of the primary base plate and expanding base plate. The slide roller bearing on the inside of the primary base plate would allow the expanding base plate to slide out easily.

The tray has a primary frame floor in the form of a stainless steel plate, and support tines are attached to the primary frame floor to hold items vertically. The support tines are stainless steel wires. Disposed along the outside of the support tine assembly of the primary frame, a short distance above the primary frame floor, is a primary frame brace, preferably comprised of stainless steel wire for the purpose of supporting the dishware in the apparatus. The floor of the expansion frame is a series of stainless steel plates, welded to the expanding frame side member of the expanding frame and spaced so as to bypass the support tines attached to the primary frame floor.

In operation, the pull out tray assembly comprising of the primary frame and the extending frame with integral floors and, and support tines may be extended from the cabinet either partially or fully on the slide roller bearings and for the removal or insertion of glassware, dishware, and/or cookware. The items in the tray would be supported on or against the tines on the primary frame floor.
