Definitions

  • the invention relates to a file mechanism with a base plate made of sheet metal, two row pins protruding perpendicularly from one another on the base plate, a pivoting bracket that can be pivoted to a limited extent on the base plate between an open position and a closed position, preferably a folding bracket consisting of a bent metal wire, integrally connected to this end shield and in a swivel bearing of the end shield, acting on a cantilever of the folding bracket preferably designed as a crank against the force of a spring directly or indirectly actuating lever.
  • Folder mechanisms of this type are intended for use in letter folders, which have a file spine and a front and back cover hinged to the file spine, preferably made of stiff cardboard material.
  • the folder mechanism is riveted to the back cover near the folder back or fastened in a connector provided for this purpose.
  • the actuating lever is pivotally mounted in the upper region of the end shield on a rivet bolt which is inserted through a bore in the end shield and the lever and is secured against axial pulling off by a setting head and a rivet head.
  • the rivet bolt is an additional part that complicates the assembly and makes the end product more expensive, which has a disadvantageous effect especially in the case of a mass product such as the folder mechanism.
  • the object of the invention is to develop a folder mechanism of the type specified at the outset which is particularly simple and efficient to produce.
  • the invention is based on the idea that if the separate rivet bolt is omitted as a storage means, a considerable simplification in storage and production can be achieved.
  • a preferably deep-drawn hollow pin protruding vertically beyond the plane of the bearing plate is molded into the bearing plate, and that the actuating lever is pivotally mounted directly on the hollow pin and is secured against axial pulling away from the hollow pin.
  • the hollow journal can be used both as a journal and as a bearing bush.
  • an advantageous embodiment of the invention provides that the actuating lever has a bearing bore encompassing the bearing journal, and that the free hollow journal end projecting beyond the bearing borehole has a radially projecting flanged edge which overlaps the bearing bore rim of the actuating lever.
  • a bearing pin which extends through the hollow pin opening is formed on the actuating lever and has a radial widening or thickening at its end projecting beyond the hollow pin opening in order to secure it axially having.
  • the widening or thickening of the bearing journal can be formed either by elastic or plastic expansion of the preferably slotted journal material or as a rivet head integrally formed on the bearing journal in the course of assembly.
  • the actuating lever consists of thermoplastic plastic, the rivet head can be subsequently molded on under the action of pressure and heat at the end of the bearing journal.
  • the bearing journal formed on the actuating lever is inserted through the hollow journal from its side which projects beyond the plane of the end shield.
  • the part of the hollow pin projecting beyond the end plate level expediently also engages in an annular bearing recess in the actuating lever, so that there is a stable mounting of the actuating lever on the end plate.
  • actuating lever has a contact surface which lies flat against a guide surface of the end shield in the vicinity of the hollow pin.
  • the folder mechanism shown in the drawing consists of a base plate 10 made of sheet metal, two line-up pins 12 projecting at a distance from one another perpendicularly above the base plate 10, a folding bracket 18 pivotably mounted on mounting brackets 16 of the base plate 10, a punched-out and bent up vertically from the base plate Bearing plate 20 and an actuating lever 22 which is pivotably mounted at a bearing point 24 of the bearing plate and acts on the folding bracket 24 via a sliding curve element 28 which is present in the exemplary embodiment shown.
  • the bearing point 24 has a deep-drawn hollow pin 30 molded into the sheet metal bearing plate 20, on which the actuating lever 22 is mounted directly and is secured against axial pulling off.
  • the actuating lever 22 is attached with a bearing bore 32 to the hollow pin 30 serving as a bearing pin.
  • the hollow pin 30 is subsequently provided with a radially projecting flanged edge 34, which is the actuating lever secures against axial pulling off.
  • a molded on the actuating lever cover 36 and a recess 38 formed therein ensure that the free upper edge 40 and the flanged edge 34 of the bearing plate 20 are concealed against accidental access, so that a risk of injury to the sheet metal burrs there is avoided.
  • a bearing pin 42 is formed on the actuating lever 22 and is inserted through the hollow pin 30, which in this case serves as a bearing bush, from the protruding side of the hollow pin.
  • the bearing pin 42 is also surrounded by an annular recess 44, in which the protruding part of the hollow pin 30 engages.
  • the bearing journal 42 is provided with slots 48 at its free end which projects beyond the bearing opening 46 of the hollow journal and is spread radially outward to form a thickening.
  • FIG. 5 corresponds in principle to the embodiment according to FIG. 4.
  • the widening of the bearing journal provided for the axial securing is there, however, formed as a rivet head 50, which is subsequently molded onto the actuating lever 22 made of thermoplastic plastic using pressure and heat has been.
  • the cover formed on the actuating lever 22 covers the burring top edge 40 against accidental access from the outside.
  • the end shield has a guide surface 52 which is oriented vertically with respect to the base plate 10 and against which the actuating lever 22 bears with a contact surface 54.
  • the invention relates to a folder mechanism with a base plate 10 consisting of sheet metal, two line-up pins 12 protruding vertically on the base plate, a folding bracket 18 which can be pivoted to a limited extent on the base plate 10 between an open position and a closed position, and one protruding over the base plate 10, in one piece therewith connected end shield 20 and an actuating lever 22 which is pivotally mounted in a bearing 24 of the end shield 20 and acts directly or indirectly on the transfer bracket 18. while the actuating lever 22 is pivotally mounted directly on the hollow pin 30 and is secured against axial withdrawal from the hollow pin 30.
  • the hollow journal can serve as a journal for a bearing bore 32 arranged on the actuating lever or as a bearing bush for a journal 42 formed on the actuating lever 22.
  • a journal for a bearing bore 32 arranged on the actuating lever or as a bearing bush for a journal 42 formed on the actuating lever 22.
  • either the hollow pin or the bearing pin formed on the actuating lever 22 is to be radially expanded or thickened in the course of the lever assembly to form a corresponding thickening.
