Container for tape cassettes

The invention relates to a container for audio tape cassettes according to the type of the main claim.

A container for audio cassettes is known from DE-OS 33 07 451, in which the slide, on which an audio cassette can be placed, can be pushed into a housing against a spring force. When pushed in, the slide engages in a recess with springy tongues and a locking element arranged on it. The tongue made of plastic material, which is molded onto the slide, is in a deflected position in the locking position, so that the tongue is pre-tensioned in the locking position. If exposed to strong heat, this can result in the tongue losing its elasticity in the locking position and unlocking is therefore no longer possible.

The invention is based on the object of creating a container with a slide in which the locking and unlocking function is not significantly impaired even at higher ambient temperatures.

This problem is solved by the features specified in the main claim. Because the tongue is in the relaxed normal position in the locking position, permanent deformation due to the effects of normal ambient temperatures is reliably avoided. The usual ambient temperatures are in particular the interior temperatures of motor vehicles, which can rise to well over 50 ^° C due to direct sunlight.

The elastic tongue preferably engages with a lateral projection in a groove 1n of the locking position, from which the projection can be removed by slightly pushing the slider back along a

f ments of Figure 2,

Figure 4 shows section AB from Figure 3 and Figure 5 shows section CD from Figure 4.

In Figure 1, a cassette storage container is shown which consists of a housing 1 and a slide 2 which can be inserted into the housing 1. A front panel 3 is formed on the slide 2, with which the open narrow side 4 of the housing 1 can be closed. The slide 2 can be inserted into the housing 1 against the spring force of an indicated compression spring 5, whereby one of the

shaped tongues 6, 7 can be deflected along a guide 8 until the elastic tongue 6 springs back into a locking position. A corresponding guide could also be provided for deflecting and locking the tongue 7.

In Figure 2, the slider 2 and thus also the tongue 6 are in the locking position. A pin 9 protruding downwards from the tongue 6, which forms the locking element, engages in a recess 10 on the base 11 of the housing 1. The pin 9 and a lateral projection 12 are located at the spring-loaded end of the tongue 6, which is designed as a long web.

The slider 2 can be unlocked from the position shown in Fig. 2 by pushing the slider 2 slightly into the housing by applying pressure in the direction of arrow 13 to the front panel 3, whereby the projection 12 is guided along two slopes, first sideways and then upwards, so that the pin 9 moves from the locking position into an unlocking position. The slider 2 can then be transported back into the position according to Fig. 1 using the spring force of the spring 5.

The unlocking process is explained in more detail using the detailed drawings shown in Figure 3 to Figure 5.

In Figure 3, the tongue 6 is in the locking position as shown in Figure 2. The projection 12 engages in a lateral groove 14 which extends from a first bevel 15 to a second bevel

16 stirs.

In Figure 4, which shows the section along the section line AB indicated in Figure 3, it can be seen that the groove 14 is located laterally in a raised area 17 formed on the base 11. The raised area

17 can also be referred to as a web or ramp. Furthermore, Figure 4 shows in particular the arrangement of the round pin 9.

formed locking element, which engages in the recess 10.

Figure 5 shows the section along the section line CD according to Figure 4. Here, the course of the two bevels 15, 16 is particularly clearly visible. If the tongue 6 is moved in the direction of the arrow 13, the bevel 15 initially causes the tongue 6 to be deflected to the right until the projection 12 has left the groove 14 and reaches the second bevel 16. The second bevel 16 moves the projection Y1 upwards out of the image plane, so that the tongue 6 with its pin 9 is also lifted from the container base 11.

As soon as the projection 12 reaches the position 18, it is located on the surface 19 (Figure 4) of the elevation 17 and can spring back to the left, whereby the projection 12 overlaps the surface 19 so far that the projection 12 can no longer slide downwards along the slope 16. Rather, the projection 12 rests on the surface 19 until it leaves the surface 19 in the direction 20 (Figure 3) at its end 21. The slide can then continue to move with spring force into the removal position as shown in Figure 1.

With simple means, a functionally reliable locking and unlocking mechanism for the slider is achieved, which is a so-called push-push solution.

Container for audio tape cassettes or similar recording media with a slider that can be pushed into a housing against a spring force, on which the cassette can be moved from the housing from a locking position to a removal position, with an elastic tongue on the slider that protrudes in the direction of movement and on which a locking element is arranged, with a guide formed on the housing that deflects the locking element from the relaxed normal position when the slider is pushed into the housing, with a locking stop against which the locking element rests in the locking position and with an unlocking curve along which the locking element can be deflected from the locking position, characterized in that the tongue (6) is in the relaxed normal position in the locking position. 2. Container according to claim 1, characterized in that a lateral projection (12) protrudes from the tongue (6), which in the locking position engages in a groove (14) made of ¹ · which can be pushed out horizontally along a first slope (15) and can be deflected into an unlocking position via a second slope (16) perpendicular to a sliding surface (19). 3.
