Index tray

The invention relates to a card trough or the like. with at least one cover part that is on the The edge of the trough can be moved laterally iat.

Index trays of this type with a lid of one half of the trough can be moved over the other half * are already known. Bs Such an index trough has also already been proposed, which can be made of sheet metal. On two opposite hands this one

Troughs are arranged upwardly protruding rails on irelohen $ n the inside of the lid edge Bearing rollers with lateral sliding surfaces rest. This proposed execution £ orm has the brook part that the shifting device a relatively large manufacturing effort? thing, which is caused in particular by the formation and attachment of plastic trenches on the trough lid will.

The present invention had the object augrunde ₉ © provide a displacement device au, which requires less production cost and which also permits a relatively good AbshluS between Deokel and trough that dae penetration of dust into the index trough eo is difficult.

According to the invention, this object is achieved by that the lid has a GKLeIttollen on its underside O.' Like. Is provided with which he is on preferably also made of plastic sliding rails rests on the 'Irogrand. According to the invention trained index trough has no RoIlglieder but easy-to-assemble sliding elements.

Lid and trough, which are made of sheet metal in inherently known Xanten tob s® & ± eimm & er overlying straps, can each be stranded with a Sic & e, Hinne, Sut or the like, in which the Sliding blocks or the (Jleitacliien tied or inlaid. The® © linmen are kept so low that they are together
G-guide organs can be brought without difficulty in such a way that the Earteitro ^ and s © in the lid in the area of the outer edges of their ligaments come close to one another when the lid is on, so that there is only a very narrow gap between the two ropes, which prevents dust from penetrating erohwert.

Further meriaaale of the invention also result the following description in connection with of the drawing on which an implementation game is played of a erfiTichmgBgQssäS trained Eartoitrogea is represented more or less eohejzatic.

As can be seen from FIG. 2, the X & trough 2 and its cover 5 are made from a sheet metal blank. The trough 2 consists of a base plate 4 and side walls 5, the upper hand 5a of which is bevelled to the inside of the trough. Parallel to the outer side walls 5 run inner side walls 6, the lower edge of which is connected to the bottom 4 of the trough in a manner not shown, for example by spot welding, while at its upper edge it is formed into a channel 7 open upwards and towards the interior of the trough and their upper end 6a is angled so that it runs parallel to the upper edge 5a of the outer side wall 5 sum.

The formation of the edges of the trough and the lid can be seen from the sectional view in Figure 1, which shows a detail of the index trough In Figure 2, designated by the Bosugsaiffer. 1 It can be seen from it that in the channel 7 formed by the inner edge of the side walls of the trough a plastic rail 8 with an angled profile is inserted and preferably anchored by gluing. The rail is made of a plastic with a low coefficient of friction, for example

also known under the trade name "Teflon" em plastic.

The hands of the cover plate 9 of the cover 3 are bent to the side walls 10 and to the inwardly directed wall parts 11, the ends of which are in turn bent to form a channel 12 in which sliding lugs 13 made of plastic protruding downward over the wall parts 11 are fastened . These © slide studs »13 rest on the horizontal limb of the slide rail 8 and are secured against lateral displacement by the shorter, upwardly directed limb 8a of the profile rail 8“ which covers at least part of the vertical band of the channel 7. The upper end section 5a of the outer side wall 5 and the inwardly directed wall part 11 of the lid 5 run parallel to one another at a small distance when the lid 3 is on, so that there is only a narrow slot 14 between the lid and the trough.

Instead of one and one ₉ sliding studs fastened in the Hiaae 12 of the cover 3, plastic webs could also be fastened in the channel 12, which have a slide shoe protruding downwards.
