Definitions
- the invention relates to a file mechanism with a base plate made of sheet metal, two line-up pins protruding substantially perpendicularly from one another on the base plate, one delimited at a distance from the line-up pins by means of a bearing web on the base plate between an open position and a closed position pivotable, two folding brackets held by the bearing web at a distance from the aligning pins and having coupling legs which can be coupled in pairs in the closed position, a folding bracket in the area between the aligning pins and the folding bracket projecting essentially vertically above the base plate and integrally connected to it Bearing plate and on the side of the folding bracket on the bearing plate about a bearing axis running transversely to the axis of the bearing web between an open position and a closed position, with a hold-down member on a crank of the bearing web against the force of a return spring actuating lever.
- the folder mechanism is intended for letter folders which consist of a folder spine and a front and rear cover articulated thereon.
- the folder mechanism is attached to the back cover of the letter folder near the back of the folder, preferably riveted or in a holder provided for this purpose is inserted so that the folding bracket can be pivoted into an open position by actuating the lever in the direction of the file spine while opening an opening between the line-up pins and folding legs.
- perforated documents can be inserted or removed on the side of the line-up pins after previously existing layers of documents, if any, have been transferred to the folding bracket with the mechanism still closed.
- the folder mechanism reaches with its alignment pins and its folding bracket from the rear cover through the folder to the front cover and, if necessary, engages with the bent ends of the folding legs in push-through slots of the front cover provided with latching lugs.
- a one-piece metal lever made of a bent round wire is provided, which is articulated at one end by means of a rivet to a bearing plate bent out of the base plate and arranged eccentrically in a knee area of the lever , a plastic hose or a profile roller bearing the steel pin as a holding-down element from above against the crank arm offset.
- the forming of the wire material used for lever production is very time-consuming. The cycle time of the relevant production tools is therefore limited, so that a large number of individual tools are necessary in order to achieve the number of pieces required for mass production. Out- it comes to the fact that the forming of the wire material is strictly limited. The molding of a rivet stub or a holding-down device has proven to be impractical.
- the invention is based on the object of improving a file mechanism of the type specified at the outset in such a way that the number of individual parts required for production is reduced and production is simplified.
- the solution according to the invention is based on the knowledge that when deep-drawn metal sheet is used as the starting material for the manufacture of the actuating lever, there are various design options in the embossing and deep-drawing process which, even in the case of high cycle rates in progressive composite tools, provide one-piece attachment enable additional functional elements on the lever.
- the actuating lever is designed as an embossed part made of sheet metal, which has a side flank which is oriented essentially parallel to the plane of the bearing plate and at its end on the bearing side merges into a sliding bearing surface bearing against the bearing plate another on the base plate - 4 -
- the slide bearing surface is arranged on a protrusion of the side flank which protrudes in the direction of the end shield and is preferably circular in outline.
- a partially circular punch-out which is concentric with the bearing axis can be provided, into which a stop tab bent on the bearing plate in the direction of the actuating lever engages in such a way that the operating lever strikes against it in the open position with an edge of the punch-out .
- the stop flap partially engages from the end shield into the depression in the side flank formed by the expression, without projecting beyond its surface.
- the actuating lever expediently strikes the base plate with the free, preferably flattened lower edge of its side flank bent in the longitudinal extent of the actuating lever.
- a further preferred embodiment of the invention provides that the embossing part forming the actuating lever consists of a deep-drawable metal sheet, so that on the side flank of the actuating lever in the region of the slide bearing surface a protruding vertically above it and passing through a bearing bore of the bearing plate and engaging with it can be molded on with its flanged rivet head behind the rivet. It is thus possible to arrange the power transmission in the area of the hold-down device and at the pivot bearing location almost vertically one above the other, so that the bending moments acting on the pivot bearing are reduced to a minimum.
- a cantilever projecting in the direction of the base plate onto which, preferably from below, a slide shoe, which forms the holding element and bears against the crank arm offset, is preferably made of plastic snaps.
- the slide shoe has a latching cam which engages in the foot pocket and can be latched into a latching recess of the arm which is preferably open towards the part-circular recess and is preferably arranged on a latching tongue formed on the slide shoe.
- the slide shoe has a track edge which engages behind the bearing web offset on the side of the bearing plate.
- a line or surface contact instead of a point-like contact of the sliding shoe on the bearing web can be achieved by the sliding shoe having a concave sliding surface which is adapted to the contour of the bearing web and is delimited by the track edge.
- the opening width between the alignment pins and the folding bracket can be increased in that the bearing web in the region of its offset has a transverse offset projecting like a roof with a run-up slope for the slide shoe.
- the slide shoe can have two latching and run-up surfaces which form an obtuse angle and which lie against the transverse offset.
- the handle piece bent in its longitudinal extent opposite to the actuating lever towards its free end and expediently has a concave or convex embossed grip at right angles to its longitudinal extent.

- Fig. 8 shows a section along the section line VIII-VIII of Fig. 7c.
- the folder mechanism shown in the drawing essentially consists of a base plate 10 made of metal sheet, two line-up pins 12 projecting at a distance from one another perpendicularly above the base plate 10, and by means of a bearing web 14 on bearing tabs 16 of the base plate 10 about a pivot axis fixed to the base plate between an open position and a closed position, pivotable folding bracket 18, a return spring 24 clamped on the base plate and acting against a crank 26 of the folding bracket under pretension in the direction of the open position, and a return spring pivotably mounted on a base plate fixed bearing plate 20, from above against the crank 26 of the folding bracket 18 with a hold-down element 28 acting actuating lever 22.

It has a side flank 32 which is oriented essentially parallel to the plane of the bearing plate and at its end on the bearing side merges into a sliding bearing surface 30 abutting against the bearing plate and has a side edge 32 which is essentially perpendicularly bent on its upper edge remote from the base plate 10 and at its end remote from the bearing in the longitudinal extension of the actuating lever 22 over the side flanges ke 32 in a widened handle 34 transversing transverse flank 36.
- the side flank 32 has a greater width than the transverse flank 36 (cf. FIG.
- the transverse flank 36 is folded on the side flank 32 in the direction of the end shield 30 and the alignment pins 12.
- the handle 34 is bent in its longitudinal extent opposite to the actuating lever 22 towards its free end and there has a concave handle 74 from above.

Furthermore, in the central region of the protrusion 38 there is a protrusion which protrudes vertically above the sliding bearing surface 30 and extends through a bearing bore in the end shield and integrally formed on this with its flanged edge 40 engaging behind hollow rivet 42.
- the actuating lever 22 strikes against the base plate 10 with the free lower edge 44 of its side flank 32 which is bent in the longitudinal direction.
- a part-circular punch 48 is provided which is concentric with the bearing axis 46 and into which a stop tab 50 bent on the end plate 20 in the direction of the actuating lever 22 engages.
