Abstract

Compact disks, which are sensitive, optically readable information storage media, may be gently taken out of transport housing having central retaining teeth by centrally pressing on the compact disk a disk-shaped base body (1) centrally provided with a stud (3) and having several suckers (2) arranged in its marginal area. The compact disk is thus loosened from its housing and adheres in a detachable manner to the device.

Description

Aufnahmevorrichtung für CD (Compact Disc)Recording device for CD (Compact Disc)
Die Erfindung betrifft eine Aufnahmevorrichtung für CD (Compact Disc) zum Herausnehmen aus einem Transportgehäuse, zum Trans¬ port zum CD-Spieler und schließlich zum Wiederaufnehmen nach dem Abspielen und Wiedereinlegen in das Transportgehäuse.The invention relates to a recording device for CD (Compact Disc) for removal from a transport housing, for transport to the CD player and finally for re-recording after playing and reinserting it in the transport housing.
Es ist üblich, CD's aus dem allgemein bekannten Verkaufs- und Transportgehäuse herauszunehmem, indem möglichst vorsichtig mit dem Finger an einer Stelle der Rand der CD angehoben wird, bis die durch das mittige Loch der CD durchgreifende, aus einem Ring von elastischen Zähnen gebildete Transportsicherung nach¬ gibt.It is customary to remove CD's from the well-known sales and transport housing by lifting the edge of the CD with one finger as carefully as possible until the transport lock formed by a ring of elastic teeth penetrates through the central hole of the CD ¬ there.
Insbesondere bei noch neuen CD springt diese dann mehr oder we¬ niger abrupt aus der Transporthülle. Dieses zu vermeiden, wird versucht, die CD im Moment des Herausspringens festzuhalten, was oft dazu führt, das mit den Fingern auf die optisch abzuta¬ stende Seite der CD gefaßt wird. Die dabei hinterlassenen orga¬ nischen Substanzen könnnen dann die Ursache für Wiedergabefeh¬ ler sein. Zur Vermeidung dieses Mangels wurde bereits eine Transportvor¬ richtung für plattenförmige Informationsträger (DE-OS 32 13 635) vorgeschlagen, die es ermöglicht, empfindliche optische lesbare Informationsträger zunächst aus einer Plattenhülle zu z'iehen und dann mittels einer aus einem aus elastischem Mate¬ rial bestehenden hohlen Handgriff mit Saugkopf bestehenden Vor¬ richtung aufzunehmen. Der zusammmengedrückte Handgriff erzeugt beim Wiederentspannen des auf der Plattenoberfläche aufgesetz¬ ten Saugkopfes einen Unterdruck und die Platte kann aufgenommen werden.In the case of a new CD in particular, it then suddenly or more suddenly jumps out of the transport case. To avoid this, an attempt is made to hold the CD in place when it pops out, which often leads to the fingers being gripped on the optically scanned side of the CD. The organic substances left behind can then be the cause of playback errors. To avoid this deficiency, a transport device for plate-shaped information carriers (DE-OS 32 13 635) has already been proposed, which makes it possible to first pull sensitive, optically readable information carriers from a plate sleeve and then by means of a plate made of elastic material existing hollow handle with suction head existing device. The compressed handle creates a negative pressure when the suction head placed on the surface of the plate is released again and the plate can be picked up.
Nachteil der genannten Transportvorrichtung ist es, das die CD in relativ einheitlicher Bauform im Bereich des Mittelloches auf der Oberseite meist ringförmig eingesenkt ist. Ein Aufsetzen des doppelwandig ausgebildeten Saugkopfes - der keine Zentrierungshilfe aufweist, ist damit erschwert und es wird meist nicht die zum Halten des notwendigen Unterdruckes erforderliche Dichtheit zwischen Plattenoberfläche und Saugkopf zu erreichen sein.It is a disadvantage of the transport device mentioned that the CD, in a relatively uniform design, is mostly recessed in a ring in the area of the center hole on the upper side. Attaching the double-walled suction head - which has no centering aid - is therefore more difficult and it will usually not be possible to achieve the tightness required between the plate surface and the suction head to maintain the necessary negative pressure.
Des weiteren muß mit der vorgenannten Transportvorrichtung beim Herausnehmen von CD's aus den bereits beschriebenen Transport¬ gehäusen die Sicherungsverzahnung mit der CD selbst überwunden werden.Furthermore, the securing toothing with the CD itself must be overcome with the aforementioned transport device when removing CD's from the transport housings already described.
Zweck der Erfindung ist es, eine CD in einer der Empfindlich¬ keit des Informationsträgers angemessenen Weise aus einem mit Sicherungsverzahnung versehenen Transportbehälter aufzunehmen und damit Beschädigungen der Platte oder Informationsverluste zu vermeiden. Der Erfindung liegt die Aufgabe zugrunde, eine Aufnahmevorrich- tung für CD's zu schaffen, die gleichzeitig mit dem Herstellen der Hauptverbindung zwischen CD und Vorrichtung die Arretierung der Sicherungsverzahnung im Mittelloch der CD löst.The purpose of the invention is to record a CD in a manner appropriate to the sensitivity of the information carrier from a transport container provided with safety teeth and thus to avoid damage to the disk or loss of information. The invention has for its object to provide a receiving device for CD's, which at the same time as the main connection between the CD and the device releases the locking of the securing teeth in the center hole of the CD.
Diese Aufgabe wird gemäß der Erfindung gelöst, indem ein am Rand trapezförmig eingesickter scheibenförmiger Grundkörper, vorzugsweise aus elastischem Kunststoff bestehend, einmal eine mittige öffung zur Aufnahme eines vorzugsweise aus Hartkunst¬ stoff bestehenden Druckbolzens und zum anderen in der Scheiben- sicke gegenüberliegende Aussparungen zur Aufnahme von elasti¬ schen Saugkörpern vorgesehen sind.This object is achieved according to the invention in that a disk-shaped base body, preferably made of elastic plastic, which is trapezoidally sunk in at the edge, has a central opening for receiving a pressure bolt, preferably made of hard plastic, and, on the other hand, recesses opposite one another in the disk bead for receiving elastic absorbent bodies are provided.
Der scheibenförmige Grundkörper wird, - wobei der Druckbolzen und die Saugkörper der Oberseite der CD zugewandt sind - auf die im Transportgehäuse befindliche CD gelegt. Indem nun auf die Oberseite des Druckbolzens leicht gedrückt wird, werden durch Niederdrücken der Sicherungsverzahnung mit der Unterseite des Druckbolzens die Zähne der Plattensicherung nach innen ge¬ drückt und die CD ist entarretiert. Gleichzeitig während dieses Vorganges haben sich die Saugkörper an der Plattenoberfläche festgesaugt. Der elastische Grundkörper gestattet es nun, die¬ sen etwas aufzubiegen, so daß die CD aus der entarretierten Si¬ cherungsverzahnung gleitet.The disk-shaped base body, with the pressure pin and the suction body facing the top of the CD, is placed on the CD located in the transport housing. By gently pressing on the top of the pressure pin, the teeth of the plate lock are pressed inwards by depressing the securing toothing with the bottom of the pressure pin, and the CD is unlocked. At the same time during this process, the absorbent bodies are sucked onto the surface of the plate. The elastic base body now allows it to be slightly bent open, so that the CD slides out of the unlocked securing toothing.
Vorteile der Erfindung liegen darin, daß beim Aufnehmen der CD keinesfalls die CD selbst gebogen wird, sondern allenfallls der Grundkörper der Vorrichtung. Zerstörungen der CD bei überdurch¬ schnittlich fester Sicherungsverzahnung werden damit ausge¬ schlossen. Ein weiterer Vorteil ist die Handhabung der CD vom Aufnehmen bis zum Wiedereinlegen in das Transportgehäuse, ohne das die CD mit den Fingern angefaßt werden muß.Advantages of the invention lie in the fact that when the CD is recorded, the CD itself is not bent under any circumstances, but rather the base body of the device. Destruction of the CD with above-average fixed locking teeth are thus excluded. Another advantage is the handling of the CD from recording to reinserting it in the transport case, without having to touch the CD with your fingers.
Mit der Erfindung wird die aus der üblichen Handhabung ergeben¬ de außerordentliche Diskrepanz zwischen Empfindlichkeit und An¬ spruch an die Leistungsfähigkeit einer CD und deren praktische Handhabung beseitigt.The invention eliminates the extraordinary discrepancy between the sensitivity and the demands on the performance of a CD and its practical handling resulting from normal handling.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel nä¬ her erläutert werden.The invention will be explained in more detail below using an exemplary embodiment.
In der zugehörigen Zeichnung zeigtIn the accompanying drawing shows
Fig. l: die schematische Darstellung der Vorrichtung in Drauf¬ sichtFig. 1: the schematic representation of the device in plan view
Fig. 2: die Vorrichtung im SchnittFig. 2: the device in section
Die Vorrichtung besteht aus dem scheibenförmigen Grundkörper 1, zwei Saugkörpern 2 und einem Druckbolzen 3.The device consists of the disk-shaped base body 1, two absorbent bodies 2 and a pressure pin 3.
Der scheibenförmige Grundkörper 1 ist am Rand mit einer trapez¬ förmigen Sicke versehen, in der die Aussparungen zur Aufnahme der Saugkörper 2 angeordnet sind. In die im Grundkörper 1 be¬ findliche mittige Bohrung wird der Druckbolzen 3 fest einge¬ setzt. Während der scheibenförmige Grundkörper 1 relativ dünnwandig ausgebildet ist und vorzugsweise aus elastischem Kunststoffma¬ terial besteht, findet für den Druckbolzen 3 vorzugsweise Hart¬ kunststoff Verwendung. Die Unterseite des Druckbolzens 3 kann noch mit einem in der Zeichnung nicht näher bezeichneten Me- tallplättchen verstärkt sein. Die in die im scheibenförmigen Grundkörper 1 befindlichen Öffnungen eingesetzten Saugkörper 2 sind aus elastischem Material saugnapfartig ausgebildet.The disk-shaped base body 1 is provided on the edge with a trapezoidal bead in which the recesses for receiving the absorbent body 2 are arranged. The pressure pin 3 is firmly inserted into the central bore in the base body 1. While the disk-shaped base body 1 is relatively thin-walled and preferably consists of elastic plastic material, hard plastic is preferably used for the pressure pin 3. The underside of the pressure pin 3 can be reinforced with a metal plate, not shown in the drawing. The suction bodies 2 inserted into the openings in the disk-shaped base body 1 are made of elastic material in the manner of a suction cup.
Zum Aufnehmen einer CD, die sich üblicherweise in einem mit Si¬ cherungsverzahnung versehenen Transportgehäuse befindet, wird die Vorrichtung - diese kann auch als "Take up" bezeichnet wer¬ den - zunächst unter leichtem Druck, den Kenndatenring im we¬ sentlichen überdeckend, auf die CD aufgelegt. Die gleichmäßige Überdeckung dienst dabei auch als visuelle Orientierungshilfe.To record a CD, which is usually located in a transport housing provided with securing teeth, the device - this can also be referred to as a "take up" - is initially under light pressure, essentially covering the characteristic data ring, onto which CD put on. The uniform coverage also serves as a visual orientation aid.
Das Entsichern der im Transportgehäuse integrierten Sicherungs¬ verzahnung erfolgt nun dadurch, daß auf den Druckbolzen - vor¬ teilhaft mit dem Zeigefinger der Hand - gedrückt wird. Durch diesen Druck werden die Zähne der Sicherung nach innen gedrückt und die CD kommt frei. Mit dem Daumen und Mittelfinger der Hand kann nunmehr die Vorrichtung am Rand leicht angehoben werden, so daß die damit über die Saugkörper 2 verbundene CD ganz aus der noch immmer entsicherten Sicherungsverzahnung gleitet. Die Vorrichtung mit der daran haftenden CD kann jetzt herausgenomm- en werden.The safety teeth integrated in the transport housing are now unlocked by pressing on the pressure bolt, advantageously with the index finger of the hand. This pressure pushes the fuse teeth inwards and the CD is released. With the thumb and middle finger of the hand, the device can now be slightly raised at the edge, so that the CD connected to it via the absorbent body 2 slides completely out of the safety teeth, which are still unlocked. The device with the CD attached to it can now be removed.
Der besondere Vorteil dieses Vorganges ist darin zu sehen, daß die CD selbst nicht auf die Sicherungsverzahnung zu deren Ent- arretierung einwirken muß und selbst auch in keiner Weise gebo¬ gen werden muß. Das Absetzen der CD auf die Aufnahme des CD-Spielers erfolgt derart, daß die Vorrichtung mit Daumen und Mittelfinger der Hand leicht zusammengedrückt wird und somit der Unterdruck in den Saugkörpern 2 beseitigt wird.The particular advantage of this process can be seen in the fact that the CD itself does not have to act on the safety toothing for unlocking it and does not itself have to be bent in any way. The CD is placed on the holder of the CD player in such a way that the device is slightly pressed together with the thumb and middle finger of the hand and the vacuum in the absorbent bodies 2 is thus eliminated.
Nach dem Abspielen der CD wird diese wieder durch leichtes Auf¬ drücken über die Saugkörper 2 mit der Vorrichtung verbunden und zum Transportgehäuse gebracht. Durch leichten Druck mit Daumen und Mittelfinger der Hand am Rand der Vorrichtung rastet die CD wieder in die Sicherungsverzahnung des Transportgehäuses ein.After the CD has been played, it is connected to the device again by pressing it lightly on the suction body 2 and brought to the transport housing. By lightly pressing the thumb and middle finger of the hand on the edge of the device, the CD snaps back into the safety teeth of the transport housing.
Die flache Bauweise der Vorrichtung gestattet es, diese auf der CD liegend, innerhalb eines geschlossenen üblichen Transportge¬ häuses zu belassen. The flat design of the device allows it to be left lying on the CD within a closed, conventional transport housing.
