MAGNETIC TAPE CASSETTE CASE. IT INCLUDES A RECEPTACLE OF THE SAID CASSETTE AND A LID CLOSING THE SAID FIRST PART, CONNECTED BY A HINGE SYSTEM. THE SAID HINGE INCLUDES A PRACTICAL HOLE IN THE RECEPTACLE AND A PIVOT 7 INTENDED TO BE FORCED INTO HOLY 8, HOLY 8, AND PIVOT 7 CONSISTING OF TWO REGIONS OF DIFFERENT WIDTHS FOR THE INTRODUCTION OF THE PIVOT INTO THE HOLE IN A DIFFERENTIAL POSITION OF THE POSITIONS OF USE OF THE BOX, THESE REGIONS PREVENT THE PIVOT FROM EXIT FROM THE HOLE WHEN THE BOX IS IN NORMAL POSITIONS OF USE.

Description

Z 508686

  The present invention relates to a magnetic tape cassette housing. In a known manner, the cassette housings comprise two parts hinged to one another; the first, generally transparent, consists of a substantially U-shaped body, one side of which is longer than the other, and which forms a receptacle or housing of the cassette, while the other part, generally manufactured in one material

  non-transparent and hinged on the first

  first part, is essentially a cover of the

  because it traps and covers the regions where-

of said first part.

  In conventional boltiers, the pivoting of the respective parts is ensured by a small pivot placed on the inner face of the housing cover and can be journalled inside a blind hole made

  in the outer face of the transparent part.

  This particular embodiment has been

  adopted because, within the transparent part of the

  PO, we have inserted a label or explanatory packaging

  on which information and illus-

  on the themes recorded on the tape.

  This label must not be damaged, when it is put in place, by protruding parts, between

  others by the hinge pin.

  The blind hole in the transparent part

  allows to obtain, in the latter, a surface area

  smoothly causing no breakage or tearing of the explanatory label, both when inserted at the manufacturing stage and when

the case itself.

  Such a rotation, however, entails some

  convenients due to the instability of the junction, and

  the fact that the small pivot can easily

shot in service of his home.

  This can often cause a dissociation of the two parts, which greatly reduces the user forced to make its cohesion to the housing by putting the two pivots in their homes. This disadvantage also occurs at the stage of the manufacture of shoemakers, made in automatic machines that lack the sensitivity that a worker could have and that could prevent a possible separation between one of the parts of the shoemaker

and the other part.

  It is therefore an object of the present invention to provide a cassette case with a system

  original pivoting mechanism to overcome the

aforementioned.

  The casing according to the invention, which gives great stability to the connection between its two parts,

  at the same time avoids rifts in the

  explanatory note, since it is equipped with appropriate organs

  adjusted to ensure the introduction of the said

  as if the inner side of this box was smooth.

  The features and advantages of the cassette case according to the invention will emerge more from the

  description below as a non-limitative example

  tif, and next to the drawing on which:

  Figure 1 is an exploded perspective illus-

  schematically tracing the case according to the invention; Figure 2 is a fragmentary section along the line II-II of Figure 1, showing one of the two side walls of the transparent portion of said casing; Figure 3 is a fragmentary longitudinal section of the other wall, along the line III-III of Figure 1;

  Figure 4 is a fragmentary elevation through

  viewed from the inside, the junction hole of the hinge solidarisant the two parts of the housing; Figure 5 is a fragmentary view showing the hinge pin inserted into said junction hole; Figure 6 is a partial side elevation of the coupling pivot of the hinge connecting the two housing parts; and Fig. 7 is a partial front elevation showing said pivot. Referring in particular to Figure 1, the housing according to the invention essentially comprises two parts, more specifically a first part 1 generally transparent and a second part 2 generally no

transparent.

  The first transparent part 1, whose confi-

  guration is known, consists of a sen-

  U-shaped and having closing side walls 3 and 4; one of the sides of this body, bearing the reference 5, is longer than its other side This first part is adjusted to form the housing

of a cassette.

  The second part 2, adjusted to form the lid closing the first part 1, is in the form of a substantially U-shaped body, whose sides

  connected by a closing wall 6, the length of which

  is substantially equal to that of the region

  lante on the extended side 5 of the first part 1.

  At the end of the part 2 and inside the latter, there are on either side of the coupling pins 7 intended to be introduced into corresponding holes 8 drilled in the walls 3 and 4 of FIG.

the first part 1.

  The pivoting system between parts 1 and 2,

  which is the distinctive feature of the pre-

  invention, will now be described in particular

in support of Figures 2 to 7.

  Each pivot 7 comprises a body shaped to

  the essential in L, of which one (7 a) of the branches is per-

  pendicular to the inner face of a side wall 9 of the second part 2 of the housing, while its other branch 7b, perpendicular to the first, forks

  outward of Part 2, that is to say,

  first part 1 in the illustrated position

in Figure 1.

  It can be seen in Figure 7 that each pivot 7

  present on its branch 7b (essentially rectangular

  two pins 10 protruding laterally and defining an enlarged area of said pivot 7, the object of which will stand out

more clearly below.

  As shown in particular in Figure 4, each hole 8 is divided into two regions: a first region

  8a, substantially rectangular, is extended by a se-

  region 8b conde circular shape.

  Therefore, to introduce the pivot 7 into the hole 8, said pivot is inserted into said hole when these two elements occupy their respective positions of Figures 4 and 7; thus, it engages the least wide area of the branch 7b of said pivot 7 in the region 8a of said hole 8, while the widest area of said branch, provided with the lugs 10, is housed in the region 8b of the hole 8 This coupling is done when the

boot maker is completely open.

  Then, the shoemaker is closed to take his po-

  use, and the holes 8 and the pivots 7 move respectively to the illustrated position

  in detail and on an enlarged scale in FIG.

  tate that the widest area (lugs 10) of the pivots 7 faces the region 8 has holes 8, while the zone

  the least broad of the branches 7 b of the pivot points 7 are

  ve next to region 8b of said holes 8.

  Under these conditions, it is impossible to extract by traction the pins 7 of the holes 8, and to uncouple

parts 1 and 2 of the housing.

  It appears from the larger-scale detail of the

  5 that the least wide area of the branch 7b of each pivot 7 always maintains its end beyond the delimitation of the region 8b, thus preventing extraction of said pivot whatever the positions

  mutual parts of parts 1 and 2 of the housing.

  In this way, and whatever the occu-

  When in use by the housing, uncoupling of its parts 1 and 2 is prevented. The relative rotation of these parts is allowed because the branch 7a of each

  pivot 7 is housed in the hole 8

  putting said uncoupling is that mentioned above.

  before, corresponding to the introduction; but, in this case, it is possible to make it difficult to extract the pivot 7 relative to the hole 8 through a tight fit, for example, between the branches 7b and the regions 8a. The possibility of damage or deterioration of the explanatory label, when it is put in place, by

  the pivots 7 protruding inside the casing, is em-

  caught by a pair of lateral ribs 11 which,

  variable, are on each side of each

  hole 8 (see in particular Figures 1 to 4).

  These ribs, extending longitudinally along the entire length of the side walls 3 and 4 of the part 1 of the

  casing, are of increasing thickness in the direction of the

  the label (Figure 3). They include in particular

  especially a beveled area 11a, forming a deflection surface ensuring the introduction of the c 8 where the label is inserted, and a planar area 11b for guiding

  this label until it is fully inserted.

  It is obvious that the beveled zone 11a ends a little before the place where each pivot 7 protrudes,

  to allow traction on the label

  above the latter In addition, the ribs 11 are of constant height so that in addition to maintaining

  the label firmly in place, they avoid any

  later tact with the pivots 7 in case of extraction.

  It goes without saying that many modifications can

  can be made to the boot described and shown, without departing from the scope of the invention Thus, it is obvious that the respective shapes of the pivots 7 and

  holes 8 may vary, but these will still

  polishing days object to ensure a single and different mating position different from the use position of the casing, and to allow the introduction of said pivots

  7 in said holes 8 by a tight fit.
