Definitions

• the invention relates to a file mechanism according to the preamble of claim 1.
• a hold-down disc is rotatably mounted on a bearing plate projecting from the base plate and carries three hold-down members in the form of rollers.
• the rollers are arranged at a constant angular distance from each other at the same distance from the axis of rotation of the hold-down disc.
• an operating lever on the bearing plate is limited pivotally mounted.
• the operating lever carries a pawl which engages radially out of the peripheral edge of the hold-down disc protruding cams or teeth.
• Such a mechanism in which both the opening and the closing takes place by pressure on the actuating lever, is generally referred to as a push-push mechanism.

• the length of the driver body is advantageously greater than the distance between two consecutive cams in the direction of rotation. He can not then completely dive between two cams and tilt there.
• a necessary for the transmission of force between the actuating lever and the hold-down disc rigid connection between the driver element and the actuating lever is advantageously achieved in that the actuation lever has a stop element which limits pivoting of the driver element about the driver axis in both directions by contact with the driver body.
• the driver element and / or the retaining plate can each be integrally formed. In this case, their production is preferred as an injection molded part made of plastic, which is possible without much effort.
• the driver element is expediently arranged on the short lever arm of the actuating lever, while the long lever arm has a handle. This facilitates the handling of the file mechanism.
• the long lever arm is advantageously pivotable against the force of a return spring to the base plate in order to realize the principle of a push-push mechanism.
• the actuating lever and the hold-down disc are arranged to each other that depression of the long lever arm causes a rotation of the hold-down disc by 360 ° / 2n, so that a single depression of the operating lever always results in a change between the closed position and he open position.
• one of the hold-down organs is expediently located on the offset and presses it down, while the offset engages in the open position between two hold-down members. It is preferred that the two hold-down organs on both sides of the bend at La gersteg abut, so that the crank takes a well-defined position.

• a plate spring 28 mounted in the base plate 12 engages from below.
• the crank is pressed against the spring force of the leaf spring 28 down, opening takes place due to the restoring force of the leaf spring 28th
• an upwardly projecting bearing plate 30 is integrally formed on which a hold-down disc 32 is rotatably mounted about a rotation axis 34.

• an actuating lever 40 is limited to pivot about a bearing axis 42 against the force of a return spring 44.
• the bearing axis 42 is located at a distance from the axis of rotation 34, which passes through a bent slot 46 in the shorter lever arm 48.
• a driver element 50 is also rotatably mounted, which has a driver body 52 for acting on the cam 38 and a pin 53 which is pushed through a hole 56 in the operating lever 40.
• the central axis of the pin 53, about which the driver element 50 can be pivoted against the actuating lever 40, and which is referred to below as the driver axis 54, runs at a distance from the driver body 52 and does not cut it.
• the driver body 52 is also in the axial direction via the pin 53 to engage in the interstices 72, without the pin 53 is in the way.
• a grip piece 60 is arranged at the longer lever arm 58, on which the restoring spring 44 engages and presses it upwards away from the base plate 12.
