Abstract
A filing system comprising a box file and a concertina file which is housed in the box file, the box file preferably being split into two parts along a diagonal of the end walls, so that it can be opened out onto a surface and the concertina file can then be extended out of it to allow access to the contents. In alternative forms the end walls are divided along different lines (for example into an L-shape) and the box may be formed from a blank of sheet material such as cardboard, or it may be moulded from a resilient plastics material.
Claims4
A box file in two flexibly connected parts, comprising first and second rectangular wall members flexibly connected together along a common side edge, wherein said first and second wall members are coplanar when the box file is opened on a flat surface;
- a further wall member rigidly connected to each of said first and second wall members at an edge opposite to said common side edge and each said further wall member extending at right angles to a respective one of said first and second wall members so as to form a box when the two parts are closed together;
- retaining means, carried internally of one of said box parts, and adapted to cooperate with an expanding file to be retained in said box;
- whereby said expanding file can be extended out onto an inside surface of said second wall member, when said box is opened;
- the box also having end walls each of which is divided along a diagonal line from a corner at an end of said common side edge, to an opposite corner, so as to facilitate access to an interior when the box is opened;
- and further comprising catch means adapted to hold the box in its closed condition, said catch means comprising a first catch member, mounted at a free edge of one of said first and second wall members and including a projecting tongue, and a second cooperating catch member, which is channel shaped so as to fit onto a free edge of the said further wall member which is connected to the other of said first and second wall members, whereby said channel shaped member forms a detent for said tongue.
