The invention relates to a cassette for storing elongated objects, in particular tools such as twist drills or the like.

• a) with a rectangular container,
• b) with a hinged lid for the container,
• c) with a first pivoting insert remote from the lid in the container for receiving the objects, which is pivotably mounted about a pivoting axis parallel to the pivoting axis of the lid and extending through the container and can be pivoted up automatically when the lid is opened,
• d) with at least one second swivel insert for receiving the objects, which is arranged between the cover and the first swivel insert in the swivel range of both and is pivotably mounted about a swivel axis parallel to the swivel axis of the cover and extending through the container, and
• e) with at least one connecting link between swivel inserts and cover.

Such a cassette is described in US-A-30 74 539. The swivel insert immediately adjacent to the cover is connected to the cover itself by means of movable connecting members. Two other connecting elements, which are independent of this, connect the swivel inserts to one another. These connecting elements are articulated to surfaces of the swivel inserts which are perpendicular to the swivel axes. A disadvantage of this known cassette is the complicated outlay for the additional connecting elements, which make the cassette more expensive and also cost space.

The object of the present invention is therefore to propose a generic cassette that is cheaper to manufacture and offers better use of space.

This object is achieved in that the connecting member passes from the cover to the swivel insert remote from the cover and thereby passes through all further swivel inserts.

Due to the direct connection of the cover with the first swivel insert not adjacent to it, the other connecting elements are completely eliminated. If the cover is swung up, it pulls by means of the connecting link the first swivel insert also with high. The second swivel insert lying between the cover and the first swivel insert is carried along by the first swivel insert. When the cassette is closed, the cover pivots the first pivot element into the container by means of the connecting member and pushes the second pivot element itself.

In another cassette known from DE-C-24 61 766, two pivoting inserts are arranged so as to be pivotable about a common pivoting axis and have support members in their lower region which abut one another and cause the pivoting inserts to take one another when pivoting up and down. A link is movably attached to the lid and to the immediately adjacent swivel insert. A disadvantage of such a cassette is that additional elements are required on the swivel inserts in order to be able to store them on a common swivel axis. In addition, the extent in the swivel axis direction of the two swivel inserts must be different, which on the one hand complicates the manufacture and on the other hand costs space.

The storage of both swivel inserts on a common swivel axis also has the disadvantage that the elongated objects to be stored in the swivel inserts are no longer directly above the swivel axis when the cassette is open. When removing or inserting an object, for example a larger twist drill, the torque balance around the pivot axis changes accordingly. In order to prevent the cassette from being inadvertently closed, the lid and the pivoting inserts themselves must be made relatively heavy, which means that they can tip over to prevent the entire cassette, also requires a correspondingly heavy training of the container itself.

These problems do not occur in a preferred embodiment of the invention. It is characterized in that the side walls of the container have lugs which, when the second pivoting insert is upright, bear against the side of the second pivoting insert facing the cover. In this way you prevent the two pivoting inserts from being pivoted beyond the upright position. With their center of gravity, inserted objects lie exactly above the swivel axis assigned to them and do not influence the torque balance. An unintentional collapse of the cassette when removing or inserting heavy objects is avoided without having to use particularly heavy materials to build the cassette.

The connecting member preferably extends from the pivot insert remote from the cover through openings in the second pivot insert to the cover. This makes it possible to use the full width of the container in the swivel axis direction for both swivel inserts.

In one embodiment, which is suitable for accommodating a large number of elongated objects, at least one of the swivel inserts has two parallel rows of storage spaces. This reduces the use of equipment and materials.

Further preferred features of the invention are characterized in the subclaims.

3 shows a top view of the opened cassette from FIG. 3.

A cuboid-shaped container 10 has two parallel longitudinal walls 11, 12, two transverse walls 13, 14 perpendicular to it and a bottom 15. Inside the container 10 there is an oblique to the other walls in a corner formed by the longitudinal wall 12 and the transverse wall 13 Oblique wall 16 standing vertically on the floor 15. Two handles 17, 18 are fastened to the transverse wall 12.

A rectangular cover 20 is articulated on the upper edge of the transverse wall 14. It can be pivoted about a pivot axis 21 which runs adjacent to the upper edge of the transverse wall 14 and is defined by two joints 22, 23. At the end of the cover 20 facing away from the pivot axis 21, a handle 24 is arranged.

A first pivot insert 30 is located in the vicinity of the transverse wall 14. It can be pivoted about a pivot axis 31 parallel to the pivot axis 21 of the cover 20.

The pivot axis 31 passes through the longitudinal walls 11 and 12 of the container 10 and can be defined, for example, by rivets. The swivel insert 30 is largely cuboid; its extension in the direction of the swivel axis is somewhat less than the length of the transverse walls 13, 14. The swivel axis 31 is close to a side of the swivel insert 30 that is rounded in the exemplary embodiment shown in FIGS. 1 and 2. The side of the swivel side remote from this rounded side of the Swivel insert 30 is formed by two parallel perforated webs 32, 33 with aligned holes. The holes delimit cylindrical storage spaces 34 for elongated objects G. Inside the swivel insert 30 there are parallel contact surfaces 35 without holes at different distances from the perforated webs 32, 33. The contact surfaces 35 do not extend over the entire width of the swivel insert 30, but instead are each limited to the width of one or more storage spaces 34. They close off individual storage spaces 34 on the side opposite the perforated webs 33.

A second swivel insert 40 is arranged between the first swivel insert 30 and the transverse wall 14 of the container 10. It can be pivoted about a pivot axis 41 parallel to the pivot axes 21 and 31, which, like the pivot axis 31, passes through the longitudinal walls 11, 12, but closer to its upper edge than the pivot axis 31. The second pivot insert 40 is configured similarly to the first pivot insert 30. It has on the side remote from the axis two parallel perforated webs 42, 43 with holes that delimit cylindrical storage spaces 44, and in the area near the axis, contact surfaces 45 parallel to it the perforated webs 42, 43. The walls of the second pivot insert 40 which are parallel to the pivot axis 41 and perpendicular to the perforated webs 42, 43 have openings 46 in the central region (indicated schematically in FIG. 2).

The longitudinal walls 11, 12 have lugs 19 bent into the container 10 at the same distance from the transverse wall 14 above the pivot axis 41 and between the pivot axis 41 and the transverse wall 14. When the swivel insert 40 is upright, the lugs 19 lie on the wall of the cross wall 14 facing Swivel insert 40 on.

A connecting member 50 connects the cover 20 to the first pivot insert 30. The connecting member 50 consists of a U-shaped wire piece, the legs of which extend parallel through the opening 46 in the second pivot insert 40 perpendicular to the pivot axis 41, run out as hooks 51 and in eyelets are hooked in the area away from the axis on the side of the first swivel insert 30 facing the cover 20. The base of the connecting member 50 connecting the two legs of the wire piece is guided through a notch 25 in the cover 20. The two legs each lead exactly through spaces between two storage spaces 44 through the second swivel insert 40. They enclose one of the storage spaces 44 between them.

To use the cassette, objects G are inserted through the holes in the perforated webs 32, 33 and 42, 43 into the storage spaces 34, 44 in the swivel inserts 30, 40 when the cassette is open. The elongated objects G, in the illustration twist drills, stand with their lower ends on the contact surfaces 35 and 45.

To close the cassette, the lid 20 is closed by means of the handle 24, i.e. pivoted about the pivot axis 21 (to the right in Fig. 1). The connecting member 50 thereby pivots the first pivot insert 30 in the same direction of rotation and the pivot axis 31. The second pivot insert 40 initially remains stationary until the inside of the cover 20 abuts against its upper edge or against the objects G inserted into it. A further pivoting of the lid 20 also takes the second pivoting insert 40 with it and pivots it about the pivoting axis 41. When the cover 20 is completely closed, the two pivoting inserts 30, 40 lie one above the other in the container 10. The inclined wall 16 prevents shorter, If the cassette is shaken, objects G to be inserted into storage spaces 34, 44 adjacent to side wall 12 slide out of swivel inserts 30, 40.

To open the cassette, the handles 17, 18 and 24 are pressed apart. As a result, the cover 20 rises.

The connecting member 50 pulls the first swivel insert 30 with it while the cover 20 is folded up about the swivel axis 21. The latter swivels about the swivel axis 31. The second swivel insert 40 lying above the first swivel insert 30 is taken along and swiveled about its swivel axis 41. This process continues until the second swivel insert 40 bumps against the lugs 19 on the longitudinal walls 11, 12. This happens when both swivel inserts 30, 40 and the objects G inserted into them are vertical. At this moment, the cover 20 is already somewhat beyond its vertical position, the opening angle of the cassette is approximately 100 °. The connector 50 holds the lid 20 and prevents it from opening further. At the same time, the cover 20 pulls on the first swivel insert 30 by means of the connecting member 50. The weight of the cover 20 thus prevents the swivel inserts 30, 40 from tipping over unintentionally and the cassette closing itself. The objects G are now available for use and can be removed from the swivel inserts 30.40. Since they are essentially exactly above the pivot axes 31, 41, no change in the torque balance occurs when the objects G are removed or inserted.

The embodiment shown in FIGS. 3 and 4 largely corresponds to the first, described above.

The main differences are in the design of the swivel inserts 30 and 40. The first swivel insert 30 remote from the cover has four parallel perforated webs 32a, 32b, 33a, 33b on its side remote from the axis, two of which are arranged one above the other and have aligned holes. As a result, two parallel rows of holes are formed, which accordingly delimit two parallel rows of cylindrical storage spaces 34 for the elongated objects G. Each of the two rows of storage rooms 34 contact areas 35 are assigned. An intermediate wall 37 is provided here between the two rows perpendicular to the contact surfaces 35.

In this exemplary embodiment, the second swivel insert 40 is each adjacent to a projection 47 and provided parallel to the longitudinal walls 11 and 12. The pivot axis 41 runs through these projections 47.

The operation when opening and closing the cassette corresponds to that of the first embodiment. However, the objects G are not all above the pivot axes 31, 41 in the open position.
