WAYS OF CARRYING OUT THE INVENTION

The safety container 1 of FIG. 1 has two chambers 2 and 3 on, which are separated by a partition 4. In the larger chamber 2 is a CD cassette 5 in the direction of shown arrow (insertion direction) partially inserted. There is a locking device 6 in the smaller chamber 3 arranged which a rear part 7 and a front part 8 includes.

The rear part 7 shown separately in FIG. 9 is approximately rod-shaped and longitudinally displaceable in the chamber 3, wherein a front end stop is formed by a housing rib 3.1 is. Fig. 1 shows the rear part 7 at this end stop. The front section 7.1 of the rear part 7 has a round Cross section on. The rear end of the rear part 7 is one Provide detent 7.2. Furthermore there is an angle element with one protruding inwards into the larger chamber 2 Leg 7.3 attached. In the middle of the rear part a receptacle 7.4 is provided for a spring 9, which is supported on the mentioned housing rib 3.1 and the rear Part 7 acts against the direction of insertion of the cassette 5 or this under tension in the position shown the front also formed by the housing rib 3.1 End stop holds.

The front part 8 shown separately in FIG Locking device 6 is a round sleeve, which on the front round end section 7.1 of the rear part 7 is attached. The sleeve 8 is provided with a backdrop 8.1, in which one in the front end portion 7.1 of the rear Part 7 recessed pin 7.5 engages. The sleeve 8 is farther rotatable in the chamber 3 about its longitudinal axis stored and at its front end with a side protruding eccentric arm 8.2. The backdrop 8.1 is like this shaped that when the rear Part 7 of the front part 8 because of the explained The engagement connection is forced to turn. The two parts 7 and 8 of the locking device are thus forcibly coupled.

As already mentioned, Fig. 1 shows the rear part 7 of the Locking device 6 at its front end stop. In this position, the sleeve 8 is rotated so that the arm 8.2 out the area of the insertion opening 11 of the larger chamber 2 is pivoted out, as shown in Fig. 6. The width of the Incidentally, the insertion opening 11 is equal to the width of the Chamber 2 and selected according to the width of the cassette.

If the cassette 5 from its position shown in Fig. 1 in Direction of the arrow completely into the safety container 1 or its larger chamber 2 inserted, then it takes the rear part 7 of the locking device 6, because that attached angle element with its leg 7.3 a Grips cassette corner. The spring 9 is also additional stretched until the latch 7.2 on the rear part 7 of the Locking device 6 with the free end of one side in the container wall clamped leaf spring 12 locked. The Leaf spring 12 is biased so that its free end automatically jumps under the detent 7.2 as soon as it is in far enough Insertion direction is shifted. It consists of one magnetic material. Fig. 2 shows the container 1 with the fully inserted cassette 5 and the explained Latching.

When moving the rear part 7 of the Locking device is the front part 8 forced rotated in such a way that the arm 8.2 on the front part 8 in Insertion direction behind the cassette 5 in the area of Insert opening 11 pivots. Fig. 7 shows the sleeve 8 in this rotary position with the arm 8.2 in the insertion opening. In this position, the cassette 5 can no longer out of the container 1 can be removed.

To remove the cassette from the container 5, the Locking of the leaf spring 12 can be released with the locking lug 7.2. This is done by means of a strong magnet with which the Free end of the leaf spring 12 pulled away under the locking lug 7.2 becomes. Since this can be done from the outside and no intervention in the Chamber 3 is required, this can completely outward be trained to be closed.

After releasing the locking, under the effect of the tensioned Spring 9 of the blocking arm 8.2 from the area of the insertion opening 11 pivoted out again and then the cassette 5 the container 1 is driven out a bit so that it is easy can be recorded.

3, the floor construction of the Container 1 according to the invention can be seen. The bottom 13 is not formed closed but has window-like openings 14 and 15 on. The unrecognizable front can in principle be similarly trained. However, two are recognizable electronically detectable resonance labels 16 and 17 on the Bottom inside, in itself such a remotely detectable Element would also suffice. More details of the Container wall construction can be seen in FIGS. 4 and 5 become.

Fig. 10 shows an embodiment in which the width the chamber 2 for receiving the cassette slightly larger than that Cassette width is selected. By pulling the side wall 18 in the front narrow side of the container or by training the width of the insertion opening 11 is, however, of a kind of web 19 still limited to the cassette width. Instead of the arm 8.2 (or at least additionally) continues with this Embodiment on the sleeve-shaped front part 8 of the Locking device 6 a laterally projecting cam molded. This pivots 5 in when inserting the cassette the container 1 next to the cassette and pushes it against the opposite container wall 18. Again, according to the No longer snap the cassette out of the Containers are removed as they are caught behind the web 19 is.
