Cassette for storing elongated objects, especially tools such as twist drills and the like.

The invention relates to a cassette for storing elongated objects, especially tools such as twist drills, Taps and the like., With a bottom part, a cover part pivotally connected to it and a receiving part which can be swiveled out of your bottom part coaxially to the pivot bearing, the receiving part has a driver, which can be actuated by the cover part, for automatically pivoting out the receiving part.

Such a cassette is known from DE-OS 27 27 969. In this cassette, a pin forming the driver is arranged on the side surface of the receiving part, which pin extends through a circular arc slot in the base part and protrudes from the side surface of the base part to such an extent that it serves as a stop for the upper edge of the cover part when this is more than 270 ^υ is pivoted relative to the bottom part. The disadvantage here, however, is that the pin protrudes freely when the cassette is open, so that it can break off easily, especially in the case of cassettes made of plastic. Furthermore, dirt, drilling chips and the like can easily penetrate through the circular arc slot, which can hinder the pivoting out or back of the receiving part. Finally, the swivel range of the

Receiving part through the length of the circular arc slot limited in the bottom part; So there is no possibility of the receiving part, for example, at right angles Swivel out of the bottom part.

The invention is based on the object of designing a cassette of the type mentioned at the outset in such a way that damage on exposed parts of the pivoting device avoid that from open to contamination no use is made of leading breakthroughs inside the cassette and that the free pivoting of the receiving part is not hindered.

This object is achieved according to the invention in that the receiving part has at least one laterally protruding Bearing pin is mounted in a pin receptacle on the bottom part and the bearing pin has an end face, has the driver forming nose which is in the pivoting range of a stop piece associated with the driver protrudes from the cover part.

The advance achieved by the invention consists essentially in the fact that no additional breakthroughs are necessary in the cover or bottom part for the parts of the automatic pivoting device, rather this are arranged in the area of the pivot bearing axis and somrt are covered and protected from the outside by the cover part. Thus, the swivel range of the receiving part, at least by the swing-out direction, not hindered. Finally, in the case of cleaning or replacement of the receiving part, this can be left out more easily Remove the bottom part and re-install it in this, as there is no more difficult, protruding part of these operations Pen is present.

In a preferred embodiment of the invention, the pivot bearing is connected to two on the cover part, oppositely directed coaxial pivot pins formed in journal bearings on the bottom part and / or on Receiving part are inserted, the bearing pin or pins forming the pin bearing for the pivot pin Recesses are provided. With such a design of the swivel bearing, it is also advisable to that the cover part has two mutually parallel, edge projecting bearing tabs, the end carry the pivot pins and due to their material properties for releasable insertion of the pivot pins are mutually elastically expandable in the journal bearings. Thus, the cover part can be easily Remove from the bottom part, so can easily be replaced by a new cover part in the event of damage will.

In the following the invention is explained in more detail using an embodiment shown in the drawing; show it:

Fig. 1. A cassette according to the invention in the opened and erected state,

Fig. 2 is a longitudinal section along the pivot bearing axis through the only partially shown object according to Fig. 1,

FIG. 3 shows a section corresponding to FIG. 2 only through the lid part,

■ ί Storage of tools such as twist drills ; | is equipped, consists essentially of a floor

'^; Part 1, a cover part 2 pivotably connected to it, and an I. receiving part 2 which can be pivoted out of the base part 1. The base part 1 and the cover part 2

are connected to each other by a pivot bearing, which is supported by two opposing coaxial joint ^. pin 4 on the cover part 2 and pin bearings 5 in the

acquisition part 3 is formed. The receiving part 3 is on its side provided with bearing pins 6 which are mounted in pin receptacles 7 on the bottom part 1, the Pin bearing 5 arranged coaxially in the bearing pin 6 Bind. The receiving part 3 is with a through the cover part 2 actuatable driver 13 is provided. This driver 13 is as protruding from the bearing pin 6 on the front side Nose trained. Furthermore, the cover part 2 is provided with a stop piece adjoining the pivot pin 4 14, the driver 13 protruding into the pivoting range of the stop piece 14. In this way takes the stop piece 14 when pivoting the cover part 2 by an angle of more than 270 ° with respect to the Bottom part 1 with the driver 13 and swivels the receiving part 3 for easier removal of the tools from the Bottom part 1.

Otherwise, the cassette shown in the drawing equipped with an anti-theft device that prevents unauthorized opening of the cassette, for example in self-service

shops for the removal of individual tools, prevented. For this purpose, essentially opposite the pivot bearing, there are recesses 8 in the cover and base parts 1, 2 provided, in which a locking member, not shown in the drawing, engages when the cassette is closed can be that blocks the mutual pivoting of the cover and bottom part 1, 2. This safety link thus prevents unauthorized opening of the cassette by swiveling it open and can only be opened by it Remove the destruction from the cassette. To open the cassette on the swivel bearing by spreading it apart to prevent the bearing brackets 9 carrying the pivot pins, whereby the pivot pins 4 out of the pivot bearings 5 are released, the journal bearings 5 each have two in the clear receiving cross section on their inner circumferential surface protruding circular segment-shaped projections 10 which extend in the circumferential direction and are diametrically opposed to each other. To accommodate the projections 10, the pivot pins 4 are provided with an annular groove 11 and fertilize with free snow 12 for the passage of the Provided projections 10, wherein the cutouts 12 extend axially from the annular groove 11 to the free end of the pivot pin 4. The mutual rotation the projections 10 and the cutouts 1? is in chosen so that the axial passage of the projections 10 through the cutouts 12 only when pivoted open Lid and base part 1, 2 is possible. In the exemplary embodiment, this rotational position is chosen so that the one another Corresponding projections 10 and cutouts are pivoted open by 90 ° with respect to the base part 1 Cover part 2 face the mutual passage, so that the pivot pin only in this position 4 inserted into the pin bearing 5 or released from it can be. Prevented when the cassette is closed

on the other hand, the protruding into the annular groove 11 projection 10 axial movements of the pivot pin 4, so that this from the journal bearing 5 is not released and therefore the cassette cannot be opened at its edge on the pivot bearing side can.
