The file tray comprises a plurality of superposed file boxes (1-3) interconnected by guide-rods (4-7) in such a way that an upper box can be spaced from a lower one. For the purpose of limiting their rotation, the guide-rods are provided with stop means comprising blocking ridges (16) on heels (4a-71, 4b-7b) joined to the guide-rods. The heels co-operate with rims projecting toward the guide-rods from the edges of the boxes.

A slide file is disclosed, which comprises a file cover, a file board, a slender file base to which the respective one side end of the file cover and the file board are adhered, and an elastic slider with a sideways U-shaped transverse section extrapolated on the file base slidably in the width direction of the base and having upper and lower plates for opening or closing a paper clip portion communicated with a bonded portion of the file cover.

A spring file comprises a coiled spring, the outer flattened periphery of which is coated with abrasive particles so as to form a file face and the method of manufacturing the same. In a first arrangement of the spring file, the coiled spring has the file face coated with the abrasive particles and is joined to the tip of a hand grip. In a second arrangement, the coiled spring has the file face coated with the abrasive particles and is of considerable length and thus used portions thereof can be...
