BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention specifically relates to an expandable drawer organizer for accommodating drawers of various sizes and a method for the organization of various articles within a drawer.
2. Description of the Related Art
The efficient organization of various articles within a drawer, whether they are tools, cutlery, hardware, toiletries or other sundry items, has long presented a problem for the users of such items. One such attempt to address the problem has been by the use of boxes positioned within the drawer. However, an inherent shortcoming of this approach is the need to arrange individual boxes into a specific arrangement tailored exclusively to the drawer or other like drawers having the same dimensional configuration. Another drawback is that the boxes may not effectively utilize the drawer area, resulting in an underutilization of the drawer storage capacity, due to the ill fit of the boxes. The use of boxes also raises a durability concern for the user, especially when heavy, bulky or sharp items are concerned which, require that the user frequently replace, repair or discard the damaged boxes. Yet, another issue that this approach fails to address is that of portability; as the boxes are limited to the present configuration within drawers having similar dimensional constraints thereby creating further issues of underutilization based on the drawer area and individual box dimensions. Even if this particular limitation can be overcome, the user is subsequently presented with the time consuming and burdensome task of disassembly and reassembly of the configuration within the new location. It would be advantageous to have an organizer that overcomes the issues presented by this approach.
Another approach is the use of separators, which span either the width, or length of a drawer, which may be of either non-adjustable permanent-type, adjustable permanent-type or temporary construction. These each suffer the inherent difficulty of being specific to the drawer where they are employed and typically lack interchangeability among drawers having different dimensional configurations, this point is most pronounced with the permanently affixed and adjustable permanent-type separators. Often, these approaches require that the drawer be customized to accommodate the separators and prevent the movement or collapse of the separator when the drawer is opened or closed, especially when containing heavy articles, i.e. tools, hardware, dishes, etc. This solution in the case of adjustable permanent-type and temporary separators, like the use of the boxes before, require the user to carefully configure the arrangement of the separators to form spaces that are specific to the article(s) in question, in order to assure optimum utilization of the drawer area. In the case of the non-adjustable permanent-type separators, the user must given careful consideration to the materials to be organized in the drawer, as future modifications imposes the need to remanufacture the drawer to accommodate the new arrangement. Both non-adjustable and adjustable permanent-type separators force the user to incur the increased cost of custom drawers and related components necessary to facilitate the use these separators. In attempts to address the issue of cost concerns native to the non-adjustable and adjustable permanent-type separators; temporary separators have been introduced which, are constructed of less durable materials that often lack the structural integrity required to retain heavy articles without the separator sustaining damage. The user of such temporary separators is often faced with the repeated replacement of the separator over the lifetime of the drawer. Lastly, the use of both permanent-type and temporary separators present an impediment to cleaning the drawer base, as the individual articles must be removed to allow for cleaning the interior drawer surfaces. A device for organization of articles within a drawer that addresses the failings of this approach would be most desirable.
In an endeavor to surmount the inadequacies posed by the previous attempts to compartmentalize drawers by use of either boxes or separators, the use of expanding trays as typified by U.S. Pat. No. 5,738,425, Adjustable Drawer Organizer has been developed. Although, this device appears to remedy the aforementioned list of deficiencies presented by its precursors, there are a number of distinct new limitations that are imposed upon the user. The first being, that the configuration of these trays is fixed and inflexible, as the tray compartments cannot be rearranged to suit an individual user preference. This issue is further compounded when the expandable organizer is expanded, in such an instance the user is presented with one tray section comprising permanently affixed separators, which establish rigid constraints regarding the compartmentalization of the section, and at least one open tray section wholly devoid of any partition for optimizing the arrangement of articles in the section. This problem requires that boxes must be employed in concert with the expandable organizer to achieve an acceptable means of segregating articles within the open section(s) of the organizer. Attempts to utilize separators in the open section(s) of the organizer fail to generate configurations other than elongated compartments, which may vary from narrow to broad in width. Further efforts to customize the compartments require the user to fashion components specific to the compartment width and secure these to the tray section or separator. The resulting arrangement is a regression to the permanent-type separator approach that is specific for the drawer in question. Another significant issue regarding the drawer organizer is retaining the position of the organizer within a drawer, given a drawer of length greater than the organizer and articles of notable mass. The typical approach has been to affix feet constructed of non-slip material to the bottom of the organizer, and to rely upon gravity and friction to secure the position of the organizer within the drawer. However, when the organizer contains articles of notable mass and the drawer is opened with sufficient force, so as to impart momentum to its contents, the organizer may be slammed to the rear of the drawer and the contents may be disrupted. A device for organization of articles within a drawer that could eliminate these concerns would be of great advantage to a user.
It would be most desirable to a user to have an organizer, which overcomes the collective disadvantages posed by each of the above approaches in the storage of articles in a drawer.
SUMMARY OF THE INVENTION
The present invention, an expandable drawer organizer relates to an apparatus for segregating articles within drawers, having differing dimensional parameters. Various aspects of the invention are novel, non-obvious, and provide various advantages. While the actual nature of the present invention covered herein can only be determined with reference to the claims appended hereto, certain features, which are characteristic of the embodiments disclosed herein, are described briefly as follows.
A first aspect of the invention provides an expandable drawer tray for segregating articles in a drawer, wherein a base tray having at least one recess in one of either the front and rear side panel is slidably connected to a first nesting tray having a corresponding protuberance in one of either the front and rear side panel; wherein the base tray and first nesting tray are expanded to a predetermined length in a drawer and maintained in relative position by an locking mechanism. In a further embodiment, the assembled base tray and first nesting tray further comprising a ledge on opposing first (widthwise) side panels of the base tray and first nesting tray, which are substantially parallel to the top plane of a selected drawer. In another embodiment, the underside of the ledges that are in direct contact with the drawer may have inserts comprised of an anti-friction material, i.e. TEFLON®, melamine, plastic, polished marble, felt or other similar surface that will afford the expandable drawer organizer to glide upon the topmost edges of the drawer. In another embodiment, at least one roller may be located in the ledge so as to permit the drawer organizer to roll on the topmost edge of the drawer without damaging the drawer. This aspect is largely repeated in another embodiment of the invention having a base tray, first and second nesting tray, slidably connected with a similar locking mechanism for securing the trays at a predetermined length within a drawer. This aspect permits a user to optimize the use of the drawer space constraints without being limited to a set drawer dimensions, thus providing for interchangeability of the expandable drawer organizer and overcoming the previously mentioned portability limitations. In another embodiment the base tray may comprise a at least one angled row configured so as to provide for a unique storage arrangement for spices, medicines, hardware or other individually packaged items stored in small containers. In a further embodiment, the angled row may also have at least one position about its length of a given size and shape to accommodate a corresponding container. In a further embodiment, the angled row may be hollow and may further comprise at least one hidden storage compartment, whereby the user may place additional items. In another embodiment, either or both of the first and second nesting trays may comprise an angled row configured so as to provide for a unique storage arrangement for spices, medicines, hardware or other individually packaged items stored in small containers and may further comprise a hollow structure wherein at least one hidden storage compartment may be located, whereby the user may place additional items. In another embodiment, the base or first nesting tray may have at least one angled slot located in correspondence in the inside front and rear panels, or the inside first side panel walls, whereby a user may insert a row insert into the slot to form a row. In another embodiment, the base or first nesting tray may have at least one recess in correspondence, in the inside front and rear panels, or the inside first panel walls; that may receive a row insert having a corresponding protuberance located in a first and second end. In another embodiment at least one detachable cleat may be located at a predetermined position within the bottom panel that may secure the bottommost edge of the row insert. In a further embodiment the row insert may have at least one peg located about the bottommost edge that may be received in a corresponding hole in the bottom panel of the base tray or first nesting tray.
A second aspect of the invention provides for a detachably connected expandable partition that is tensionably extended to a predetermined length and therein secured in an angled or normal position to opposing panel walls by a locking mechanism comprising spring-loaded protuberances that are received in corresponding recesses, wherein the expandable partition may be arranged in a number of unique user defined arrangements. This aspect directly overcomes the previous need for a customized drawer tray configuration, while simultaneously maintaining the desired interchangeability of the organizer between drawers of differing dimensional constraints. In another embodiment, the expandable partition may comprise a variety of shapes to accommodate specific containers and accommodate individually packaged items to permit optimization of their storage. In a variant of this embodiment the partition may comprise a panel of a given length having a plurality of slots or recesses to receive a slotted non-expandable divider of a given length and configuration or another expandable divider oriented such that slotted elements are in agreement which may normally engage adjacent partitions, panels or the sides of the drawer directly.
