Description

The The invention relates to a closure flap assembly having a Closing flap for closing an insertion opening for a data carrier in one casing a data device, wherein the flap on opposite edge areas mutually coaxially projecting pivot pin has, which is pivotable in corresponding bearing recesses of a fixed part of housing of the data device are stored and wherein the shutter against a spring force from a closed position defined by positioning means in an open position pivotable about a pivot axis defined by the pivot pin is.

at Such a flap arrangement is known that the closing flap is acted upon by two springs in opposite directions is and in the closed position the flap the opposing forces of the Feathers are the same size.

to Definition of the closed position there is no stop against which the flap generates noise can strike.

From the US Pat. No. 3,521,888 , of the US 3,800,328 and the US Pat. No. 6,411,583 B1 Verschussklappenanordnungen are known in which the closure flaps are pivotally mounted along its one edge region about an axis and biased by torsion springs in their closed position.

These known arrangement requires an accurate adjustment of the springs, so their power balance also exactly in a defined closed position the flap is made.

The Therefore oppositely acting springs may therefore during assembly not mixed up or damaged or not mounted at all. In addition, by a plurality large on springs of assembly work.

task The invention is therefore a closure flap assembly of the beginning to create said type, which is simply constructed with few components and easy to assemble, and safe and accurate in its closed position is positionable.

These Task is inventively characterized solved, that on the flap parallel to the pivot axis an approach is arranged by pivoting the flap on one to the pivot axis concentric circular path movable and transverse to Pivot axis is acted upon by a prestressed spring, wherein the flap in the most relaxed spring in the closed position located and upon deflection of the flap from the closed position stress increasing from the approach is charged.

Preferably In this case, the approach is formed integrally with the pivot pin and forms a staggered axial continuation of the pivot pin.

There the one or more approaches are acted upon only by a spring, the assembly and component costs low.

The closed position is defined by the one or more approaches on their circle of motion are pivoted to the position in which they are the least Spring force of the springs are acted upon. A panning out this closed position, in the same direction, always leads to an increase in the Spring force, so that when not acted closure this inevitably in their closed position pans and is held there.

One noise-generating Hitting a fixed stop is avoided at the same time such is not needed to define the closed position.

There taking the closed position independently from the height is the force of the spring, the compliance of a tight force tolerance the spring is not required.

are the pivot pin at a the insertion opening having, with the casing connectable flap holding frame pivotally mounted, so is a Installation-friendly pre-assembly of a module possible.

In simple training, the spring one at its one end be fixed leaf spring, with its free other end at the approach with bias in plant is.

there can the spring with its one end to the housing or be fixed to the flap holding frame.

A possibility for cost-effective Formation of the leaf spring is that the leaf spring Metal exists.

Also Cheap It is also when the leaf spring is made of plastic.

The casing or the flap holder frame can a plastic part, in particular a plastic injection molded part.

It can special spa work rend the leaf spring by encapsulation on the housing or the flap holding frame to be fixed.

A further reduction of assembly effort is achievable, in that the leaf spring has a molded onto the housing or the flap holder frame Component is.

are the bearing recesses open against the direction of the spring force Bearing recesses, against the floors the pivot pin acted upon by the one or more springs in plant are, so are for mounting the flap only the pivot pin into the open bearing recesses. The holder of the Pivot in the bearing recess is made by the spring.

Especially in arrangements of springs in both approaches, the pivot pins always held rattle-free in contact with the bottoms of the bearing recesses.

A particularly secure locking in the closed position is achieved by that the approach has a flat loading surface on which the spring is in abutment, wherein the loading surface is in the closed position the shutter extends at right angles to the direction of force of the spring.

embodiments The invention are illustrated in the drawings and will be described in more detail below. Show it

The closure flap arrangements shown in the figures have a flap holding frame 1 on top of a rectangular insertion opening 2 has.

Through this insertion opening 2 For example, a data carrier such as an MD (mini-disk) can be inserted into the casing of a data device such as an MD player (minidisk player).

The insertion opening 2 is usually through a flap 3 closed, which is opened only for insertion of the data carrier.

These are in the upper area on both sides of the insertion 2 on the flap holder frame 1 slot-like bearing recesses 4 formed, which extend in the insertion direction of the data carrier and have at one end an open mouth.

The bottoms at the closed ends bearing recesses 4 have a semi-circular contour.

The flap 2 has at its upper end laterally projecting pivot pin 6 same diameter as the width of the bearing recesses 4 , The pivot pins 6 extend along a pivot axis 7 around which the flap is pivotable when installed.

With an axial insertion of the flap 3 in the insertion simultaneously the two pivot pins 6 until it touches the floors 5 the bearing recesses 4 introduced.

The two pivot pins 6 each have an approach as offsets 8th , which is parallel to the pivot axis 7 extends and by pivoting the flap 3 on one to the pivot axis 7 concentric circular path is movable.

At the bottom of the flap holder frame 1 are each laterally next to the insertion opening 2 with their one end leaf springs 9 . 9 ' firmly arranged. They extend approximately in an arc to the approaches 8th and lie there with their free end portions so with bias on flat Beaufschlagungsflächen 10 on that the pivot pin 6 against the floors 5 the bearing recesses 4 be pressed.

The spring force of the leaf springs 9 . 9 ' is perpendicular to the pivot axis 7 on the admission areas 10 the approaches 8th directed so that when not kraftbeaufschlagter flap 3 the approaches through the leaf springs 9 . 9 ' in their direction of spring force 11 be moved to the most deflected position. In this position is the bias of the leaf springs 9 . 9 ' least and the flap 3 is in its closed position.

In the embodiment of the 1 and 2 are the leaf springs 9 separate components of metal, as in 2 It can be seen, with its one end in a mounting recess 12 the flap holder frame 1 inserted and locked there, leaving the leaf spring 9 firmly on the formed as a plastic injection molded part flap retaining frame 1 is arranged.

In the embodiment of the 4 and 5 is the flap holder frame 1 also formed as a plastic injection molded part, wherein the leaf springs 9 ' also made of plastic and on the flap holder frame 1 are sprayed.

By the opposite the pivot pin 6 cranky training of the approaches 8th can for insertion of the data carrier in the housing of the data device, the shutter 3 be deflected from its closed position, the approaches 8th by the pivoting movement, the bias of the leaf springs 9 . 9 ' increase.

Is the opening of the shutter 3 finished, the leaf springs swing 9 . 9 ' the approaches 8th back so far back to the minimum of the bias of the leaf springs 9 . 9 ' is reached, at the same time the flap 3 takes up its closed position. Would the flap 3 pivoted beyond this closed position, it would come back to an increase in the biasing force of the leaf springs 9 . 9 ' , which in turn pivots back the flap 3 would cause in the closed position.
