Filing tray for forms

The innovation concerns a filing book for forms with Alignment pins that only have internal threads at the free end Admission of end screws or mounting bolts have, and aims to simplify production and make it cheaper.

Hitherto customary production from several parts requires additional operations in order to be able to assemble and connect them. Dimensional inaccuracies can also occur here as a result of the manufacturing tolerances of the individual parts. The production of the carrying chords with the alignment pins in one piece made of metal also entails considerable costs due to the given shape. Furthermore, the metal must be protected against oxidation.

The fire ordered that the alignment pin © and «Ine the carrier rail assigned to them as a one-piece piece Plastic is pressed and that the mounting rail with in on as is known, 'metal reinforcements' embedded in the plastic is provided, which makes the production of such books considerably cheaper and greater strength is achieved between alignment pins and rail and im further a guarantee for the precision of the spacing of the alignment pins is given, which is essential in the manufacture of such filing books. The counter rail for the Deekel is also made of plastic, as are the extension bolts to expand the book content and the. End screws. As a result, they can be manufactured significantly more cheaply, since threads, threaded bolts and lugs are not particularly rotated need to be like metal, but at the same time im Pressing process are produced. Besides, they are too easier"

It is very advantageous that both rails are not processed. For example, there is no need for cutting exact length, the rounding of the corners of the rails, that Remove the sharp burrs and the rail for the lid attaching the lasen ^ on the underside for easier clipping on the retaining pins »When using plastic the whole book becomes noticeably "lighter

On the drawing show /.■_..■ Fig. 1 is a reduced Ablagebueh in plan view, Fig. 2 in front view from the front,.

The two covers a and b of the filing book contain two rails d and b ¹ on the left edge, which are embedded in bookbinding work. As a rule, they are glued with canvas and connected to covers a and b at a ¹ or b ^H by a fold so that the book can be opened to read the bound sheets c or to be able to attach further sheets, For which the upper cover b must then be removed in order to expose the alignment pins d ' _e

The rail d consists of one piece with the outer row pins d ', ie these are no longer riveted in, but instead are molded in from plastic during the manufacture of the rail. So that the rails d and b ^{f are} sufficiently rigid, wires e are embedded during the pressing process, as indicated by dotted lines in FIG . . ■■. "■■ - ■" ■ -. -. ■■ "" .- ■■ '. "-"

In the same way, order the extension or extension bolts g, which are usually supplied, and the plastic end screws f. The rail b embedded in the upper cover b ^! has corresponding holes for the alignment pins d ^{1 to pass through.} The use of plastic for the rails d and b ^f together with alignment pins d ¹ , extension bolts g and locking screws f saves a considerable amount of weight. If desired, small, short G-thread nozzles d ″ can be molded into the alignment pins d · in order to make the thread more resistant. The extension bolts g correspond to the alignment pins d '., But they still have taps en -g' for screwing in in the alignment pins d ¹ except for the G-ewindelöehern.g "for the end screws f."
