Description

CASSETTE FOR RECEIVING TOOLS.

  The present invention relates to a cassette for receiving tools, in particular twist drills, comprising a body, a cover hinged to this body and consisting of a front wall and side walls connecting approximately perpendicularly

  at the edges of this front wall, also comprising a lining-

  support, in one or more pieces, disposed between the side walls and having, in the area of its side surfaces facing the side walls, projections in the form of elongated ribs running approximately parallel to the plane of the front wall of the cover

  and collaborating with the side walls of this cover.

  In known cassettes of this type, the support lining, separated from the cover and from the body, is furnished with tools, such as, for example, twist drills, then, in the finished packed state, it is connected to the

cover and body.

  This process has the advantage that the relative arrangement-

  compact, in the assembled state, for constructive reasons, the support lining on the cover does not interfere with the filling process, which considerably simplifies the filling of these

cassettes.

  In these known constructions, it is nevertheless dis-

  advantageous that the connection of the upholstery-support trim with the cover-

  key and the body is relatively expensive This is how the ribs of the support lining must be threaded between guide bars arranged on the side walls of the cover, which requires

  precise alignment of the support lining with respect to the cover.

  To execute this alignment, you must either have a manual adjustment,

  which takes time, that is to say the implementation of a device.

  The object of the invention is to improve a cassette

  of the type mentioned at the beginning in such a way that the connection of the trim-

  support trimmed with cover and body is simplified.

  According to the invention this object is achieved by the means that the side walls of the cover are provided with recesses corresponding to the projections of the support lining, in the form of slots which collaborate

with the projections by notching.

  Thanks to the features according to the invention, a cassette has been created for the first time in which the garnish can be locked in a simple manner with the cover without prior centering or alignment process. To do this, simply place the backing pad garnished on the internal surface of the front wall of the cover and, by light pressure, slide it into its final position between the side walls, position in which the ribs of the backing pad automatically lock into the slot side walls There is nothing to take into account

  here guide bars in which the packing should be threaded-

  support before the locking process.

  In the case of a design of the support lining in two or more parts, it is advantageous that the parts of the support lining can be inserted one into the other in a plane perpendicular to the front wall of the cover. and that it is the part furthest from the front lining of the cover which is provided with protrusions or recesses In a design of this type it is not necessary to anchor each part Much more, the different parts of the lining support can be plugged into each other in a first phase of work and then be anchored together

with the cover.

  The various parts of a cassette according to the invention can be made of any suitable material. It is however particularly advantageous that the body and the cover, as well as

  the support trim, are made of plastic, preferably of polystyrene.

  But it is also possible at any time, so

  known, to manufacture the body and the sheet metal cover and the trim-

plastic support.

  Another advantage of the cassette design according to the invention lies in the fact that in order to adapt to the tools to be received in each case, it suffices to modify the support trim but not the body and the cover. - different supports for a single body and cover, which simplifies

stock keeping.

  Other characteristics and advantages of the invention

  will emerge more clearly from the following description of a

  nonlimiting exemplary embodiment, as well as the attached drawing, in which:

  Figure 1 is a perspective view of a trim

  ture-support in two parts, shown at a distance from each other for clarity; and FIG. 2 is a perspective view of a cassette, consisting of a body and a cover, in the open state, after the

  placement in the cassette of the support trim of figure 1.

  As can be seen in the drawing, the cassette according to the invention consists of a body 1 and a cover 2 which is articulated to the body by a conventional hinged connection.

  connection can be achieved by means of rivets, buttons, or, of pre-

  ference, studs molded on the body and snapping

  in corresponding holes in the cover 2.

  The cover 2 of the example shown is formed by a front wall 3 and side walls 4 which are connected at approximately right angles to the edges of the front wall. In this example, the side walls 4 form wall areas between which is arranged a support lining 5, which in this case consists of two parts 6 and 7 (see FIG. 1) The two parts of the support lining have openings for receiving drills

  of a set of metric drills To simplify installation -

  openings not only open at the top but also

known, forward.

  The parts 6 and 7 of the support lining 5 can be inserted one inside the other in a plane perpendicular to the front wall 3 of the cover. For this purpose, the part 6 has, on the rear side, vertical edges 8 and 9 which can be

  nested in corresponding recesses 10 and 11 of part 7.

  Part 6 of the support lining, which is the part furthest from the front wall 3 of the cover, is further provided with projections 12 in the form of ribs which are arranged on the side faces 13 directed towards the side walls 4 of the cover In addition, the side walls of the cover have recesses or notches 15 in the form of slots, in which the protrusions 12 in the form of ribs snap in when

  the installation of the support lining between the side walls

covers 4 of the cover.

  As is shown in particular in FIG. 2, the cassettes produced according to the invention have very great stability when they are placed in the open state on a surface; this is due to the fact that the side wall of the cover 2 situated at the bottom when the cassette is open is in the same plane as the bottom 16 of the body 1 of the cassette, as clearly shown in FIG.

figure 2.

  The side walls of the body 1 and of the cover 2 of a cassette according to the invention have a particular shape. This is how the height of the side walls of the body 1 is relatively small in the region of the hinged connection and increases from from there to the side opposite the hinge On the other hand, the height of the side wall of the cover 2 is relatively large in the region of the hinge and decreases towards the opposite side The walls

  side of the body 1 and of the cover 2 therefore have shapes.

  roughly trapezoidal which complement each other in the closed state of the cassette In the open state (see FIG. 2), the trapezoidal shape of the cover 2 allows on the one hand a realization and a problem-free access to the recesses 15 and d on the other hand good access to forests

for their removal -
