'ADJUSTABLE LENGTH HOLDER TRAY"
* * *
Technical Field
This invention concerns a holder tray, in particular for office desks and the type divided into different compartments to house the different objects such as pens, pencils, paperclips and other items in an orderly fashion. State of the technique
Holder trays for writing desks which can be placed on a flat plane, but which are normally envisaged for placing in and sliding along the sides of a writing desk drawer, are already well known. However not all desks have drawers of the same width; so a single size holder tray cannot satisfy all requirements. In other words there is the need for holder trays with the same number of different sizes as there are widths in the drawers they are housed in. Object and Summary of the invention
This invention is aimed at remedying the above mentioned drawback and facilitating therefore the use and application of holder trays in desk drawers. The aim, in fact, of the invention is to make and provide holder trays which can adapt to all drawer widths within a wide range of sizes, always ensuring the flatness and rigidity of the tray when in use.
This aim is achieved with an adjustable length holder tray essentially comprising a main body with partitions forming several holder compartments and a sliding extension connected to the body and moving between a closed position and an extracted position to increase the length of the main body as required.

The tray shown represented comprises a main body 10 and an extension 11 connected to the body 10 by sliding.
The main body 10 is a tray and has two longitudinal walls 12, two transversal wall 13 and among said walls 12, 13, some partitions on the bottom 14 forming several compartments for different objects.
At least the two longitudinal walls 12 each have an external ledge 15, sloping downwards and which form a channel-shaped guide 16. This is open
lengthwise in line with a transversal wall 13, which can also have a ledge facing outwards, whereas the opposite transversal wall has a support fin 13'.
At the top of each longitudinal wall 12, where it joins with the respective external ledge, a guide slot 17 has been obtained having a fixed length and the external walls of which terminate in a rabbet 18.
The extension 11 is also tray shaped but without one transversal wall. It has a back wall 19, two longitudinal walls 20 and one transversal wall 21 from which projects a support fin 21 '.
Each longitudinal wall 20 has, near its free end, that is distant from the transversal wall 21, a first external tab 22 on a level with the back wall 19 and a second tab at the top 23.
The extension 11 connects to the body, by placing the two longitudinal walls 20 in the channel shaped guides 16, inserting the top tabs 23 of said longitudinal walls 20 in the guide slots 17 and at the same time fitting the external tabs 22 under the edge of the external ledge 15 of the longitudinal walls of the main body - Fig. 5.
In this way the extension 11 can be moved and positioned in relation to the main body 10 moving between an extracted and fully inserted position - Figs. 1 and 2 - limited by the top tabs 23 coming into contact with the external rabbets 18 of the guide slot 17. In the same way, it is possible to adjust the length of the tray to adapt it to the width of the drawer it is used with by resting its support fins 13', 21' on the walls of the drawer itself.
