Freely swiveling four-hole mechanism Kass _a ck KGo, Metallwarenfabrik 5860 Iserlohn

The present invention relates to a device for lining up documents in a folder, which are locked in the closed, read and open positions can.

Devices are already known in which locking levers engage in recesses in the shape of a segment of a circle and thereby lock it.

Furthermore, devices are known in which a locking disk corresponding to the retaining plates through a locking lever is locked "

In contrast, the device according to the invention is characterized by a pivot point of the pivotable retaining plates functioning, square-edged axis, which, roughly in the middle of the mechanics, is partially twisted like a screw spindle and here with a locking disk leads to an internal thread, which, with radial movement of the axis, extends as far as desired through one of the mechanics protruding handle moves axially and thus the retaining plates, on which 1 pair of arcuate alignment pins are attached, locked in closed, turning, reading and open positions «,

In Fig. 1-6 of the drawings, an embodiment of the Device according to the invention shown without the part of the folder »It show it

Figure 1 _e is a top view in reversing position, FIG »2 shows the cross section along line I -. I in Figure" I, Figure 3 is a cross section through the device in

Reading position,

Open position,
FIG. 5 shows a side view in the reading position and FIG

6 is a partial view showing a particular form of the handle.

On a base plate 1 are two bearing blocks 2 and 2 ', which have a Yierkantachse 3? secured against axial displacement by a recess 3 ', a shoulder 3 a and a shaft lock 3 ¹ O , rotatably mount, two retaining plates 4 and 4' by means of hinge sleeves 5 * 5 ¹ ? 6 and 6 * pivotally attached to the two retaining plates 4 and 4 'are riveted to each 1 pair of arcuate alignment pins 6 a and 6 b for receiving the documents.

The locking disk 8 resting on a helical compression spring 7, which has a two-stage, circular ring segment-shaped recess 9 _S with notches 9 a and 9 b, a slot-shaped recess and an internal thread 11, which corresponds to the spindle thread 11 'of the square axis 3, engages in the - and turning position of the device with its notch 9 a behind the stop 12 of the retaining plate 4,

The reading position can be locked by the catch 9 b and the stop 12 'after the locking disk 8, against the pressure of the spring 7? axially by the spindle thread 11 'so far that the stop 12 is released from the Raäte 9 a * The square axis 3 with the spindle thread 11' is set in rotation by the radial pressing down of the handle 13. Further depression of the handle moves the locking disk 8, the slot-shaped recess 10 of which is always in engagement with the holding plate 4 ', further axially in the direction of the handle 13 ₅ , the catch 9 Td ₉ passing through the recess 12 a of the holding plate 4, the device releases in open position »

In the closed position, the device is set back by ^{moving the two retaining plates 4 and 4 1} radially against each other »This is done in a known manner by closing the folder» During this process, the spring 7 returns the locking disc 8 to its starting position »

A handle IJ ¹ in another embodiment, which allows more easily accessible actuation when the folder is overfilled, is shown in FIG. 6.

Compared to the known four-hole mechanisms, the device according to the invention in particular the gate parts listed below:

The annular segment-shaped recess of the locking disk allows the locking of the retaining plates in the closed to the turning position so that the mechanism can only be activated by operating the handle can be placed in reading position, while the known devices, the holding plates between the supply and Reading position, which corresponds to the closing and turning position of this device, are freely movable « This has the advantage that on the one hand, as in the known mechanisms in the reading position, in the turn Position the documents in blocks on the alignment pins can be turned5 on the other hand, in the reading position, in which the mechanism is so wide open that the pairs of aligning pens just about overlap, the writing well turned over page by page, like in an open book will"

The retaining plates carrying the aligning pins can be produced in one operation using a suitable tool _{or the like}

The square axle supports the device and takes over ! Puncture of the control of the locking disc and at the same time, with its end leading out of the mechanism, serves as operating handle *

A cumbersome installation, with the help of tools and machines are eliminated because the device is assembled by simply plugging it together, with the Axis hold all parts together functionally and on their the end opposite the handle a shoulder and a shaft lock an only radial movement of the axis or » the device allows »
