Description
BACKGROUND OF THE INVENTION
The use of magnetic tape cassettes has increased tremendously in
recent years. As a result of the increased number of tape cassettes
used, it is increasingly a problem providing adequate means for
handling, transporting, and storing tape cassettes. Typically,
cassettes are stored in box-like receptacles or albums which can be
stored in compartmentalized library apparatus. Generally these
devices do not facilitate easy cassette handling or storage,
particularly where relatively large numbers of cassettes are in
use. In particular, when it is desired to use a cassette it is
first necessary to remove the entire cassette receptacle or album
assembly from the library compartment. Then it is still necessary
to remove the cassette from the cassette receptacle.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an
improved cassette album for enclosing a magnetic tape cassette.
It is further an object of the present invention to provide a
cassette storage library from which a magnetic tape cassette can
easily be removed.
It is further an object of the present invention to provide a
magnetic tape cassette storage library adaptable for receiving an
improved magnetic tape cassette receptacle assembly.
It is further an object of the present invention to provide
improved cassette storage library apparatus from which a magnetic
tape cassette can readily be inserted or removed.
In accordance with the present invention, a magnetic tape cassette
receptacle is provided which comprises a cassette holder and a
housing or cover member pivotally mounted thereto.
The cassette albums are stored side-by-side in a magazine or
library comprising a plurality of receiving portions or
compartments. Means are provided for engaging the albums when
inserted within receiving portions so as to allow a cassette to be
conveyed to a position outside of at least a part of the library
for easy removal or insertion of a cassette.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1 through 5 illustrate one embodiment of an improved cassette
receptacle assembly or album 10 made in accordance with the present
invention. The album 10 includes a cassette holder such as a
container box 14 for receiving a magnetic tape cassette 12. The
cassette 12 encloses a pair of reels or spools 13 between which the
magnetic tape passes. A housing structure or cover 16 encloses the
open portion of the cassette container box 14. The various
structures are preferably molded from plastic, such as
polystyrene.
In one embodiment the container box 14 has a generally rectangular
shape including a front end wall 18, two side walls 22; and a
bottom wall (not shown). Desirably, at least one of the side
sections includes a transparent portion 23 which, when the cassette
12 is stored within the container box 14, allows observance of the
amount of magnetic tape remaining on the tape spools 13. The top
portion 24 of the container box 14 is open to allow the cassette 12
to be inserted therein. The manner by which the cassette 12 is
inserted is best seen by reference to the arrow in FIG. 1.
The cassette container box 14 is pivotally mounted to cover 16
about an axis parallel those of the spools 13 when the cassette is
inserted therein. The axis extends along the lower corner portion
29 of the cassette container box 14, as best seen by reference to
FIGS. 1 and 4. The container box 14 is pivoted on a hinge
comprising two hinge axles 32 forming a part of the corner portion
29 of the container box 14.
The cover 16 into which the cassette holder 14 is pivoted, has a
generally L-shaped configuration including a top portion 34 and a
side portion 35. Perpendicular to the top and side portions 34 and
35 are spaced-apart parallel side members 30. Formed in each of the
side panels 30 at the lower end of side portion 35 of the cover 16
are holes 37 for receiving the hinged axles 32 of the cassette
container box 14.
When it is desired to place a cassette within the improved cassette
receptacle assembly of the present invention, the cassette 12 is
placed within the container box 14 as described. The container box
14 is then pivotally rotated from the opened position shown in FIG.
1, in a direction indicated by the arrow, to the closed position of
FIG. 2. In this closed position the cover 16 and cassette holder 14
form a rectangular volume generally conforming to the size and
shape of an enclosed cassette 12. When it is desired to remove a
cassette from the cassette receptacle assembly 10, the container
box 14 is pivoted to the opened position and the cassette 12 is
easily removed therefrom.
To prevent rotation of the cassette holder 14 beyond 90.degree.
from the closed to the opened position, guide channel 36 is
provided along the inner surface of the wall 30 of the lower end of
side portion 35 of the cover 16. A male member or cam 38 is
attached or formed along the corner portion 29 of the container box
14. The guide channel 36 is circular and subtends an angle of
90.degree. . The male member 38 thus prevents the container box 14
from rotating more than 90.degree. from the closed position when it
reaches the end of the guide channel 36.
The cassette holder 14 is held in the closed position (FIG. 2) by
detent means comprising a pair of protuberances 40 located at the
corner diagonally opposite from the hinge 32. These protuberances
snap into the respective female sockets 42 located along the inside
wall of the upper portion 34 of the housing structure 16.
To facilitate the insertion and removal of the cassette assembly 12
within the housing 14, guide means are provided comprising a guide
rib placed on the end wall of the cassette 12, and a female guide
slot 45 formed in the front wall 18 of the container box 14.
Each of the side walls 22 includes a recessed portion 47 to
facilitate the removal of the cassette 12. The recess 47 has a
shape which conforms to a thickened portion 48 of the cassette 12,
thereby providing a flush surface when the cassette is within the
holder 14.
To maintain the cassette 12 within the cassette holder 14 when the
cassette holder is rotated to the open position, restraining means
are provided, comprising a leaf spring 46 which is mounted at one
end to the bottom of the container box 14 and extends
perpendicularly therefrom as shown in FIG. 3. When the cassette 12
is placed within the container box 14 the leaf spring 46 is forced
outwardly as shown in FIG. 3. This results in a tangential force
about the base of the spring 46 against the cassette 12, shown in
phantom.
Alternately, the restraining means (not shown) can comprise a slot
in the back wall of the cassette holder, with the side walls 22
biased inwardly slightly. When a cassette is inserted therein the
walls are forced outwardly slightly so that a net inward force is
applied to the cassette. This inward force keeps the cassette
within the cassette holder when the latter is rotated in and out of
the closed position.
FIGS. 6 through 8 illustrate a cassette storage library 50
utilizing the receptacle assembly 10 described above. The library
includes support means such as magazine 52 for storing a plurality
of cassettes 12 in side-by-side relationship, with the broad sides
of the albums being face to face. The magazine 52 when holding a
plurality of individual cassette albums defines a library unit or
volume from which, as will be explained, individual cassettes are
withdrawn. The particular embodiment shown includes a bottom or
floor 54 and a back panel 56. A plurality of parallel, spaced-apart
walls or partitions 58 define a plurality of cassette receiving
portions or chambers 60.
The receiving chambers 60 are adapted to hold or receive a cassette
album. Restraining means are provided to positively secure the
cover portion 16 of the receptacle assembly in place when the
cassette holder 14 of the cassette assembly 10 is rotated to the
open position about the hinged members 32, in the manner described
above. As illustrated in FIG. 6, it is thereby possible to rotate
the cassette 12 from the storage position to an open position
90.degree. from the storage position, where a user can easily
remove the cassette 12 from the container box 14. As described
above the retaining leaf spring 46 holds the cassette 12 within the
cassette holder 14 when rotated out of the library volume.
In the embodiment of FIGS. 6 through 8, the restraining means
comprises a series of elongated ribbed male members 62 formed along
the length of dividing walls 58 of the magazines 52. A
corresponding female slot or guide 64 is formed along the length of
the side wall portion 30 of the cover or housing 16. The receptacle
assembly 10 is inserted into the magazine 52 in a direction
indicated by the arrow in FIG. 6. With engagement of the ribbed
portion 62 and the guide slot 64, the cover 16 is secured and is
positively prevented from being moved when the holder is rotated to
the open position. The combination of the ribbed portion 62 and the
guide slot 64 is oriented in a position perpendicular to that of
the direction of force required to begin rotation of the holder 14.
When it is desired to remove a cassette from the receptacle 10, all
that is necessary is for the user to pivot the cassette holder 14
to the open position in FIG. 6 and the cassette can be readily
removed.
To further secure the receptacle assembly 10, and in particular the
cover portion 16, biasing means are provided as a part of the
magazine 52. A modified leaf spring 66 is formed in the back wall
56 of the magazine by providing parallel slots in the wall 56.
Thus, when the cassette receptacle assembly 10 is in position, the
curved portion of the modified leaf spring 66 is forced outwardly.
This results in a net force against the assembly 10 which resists
movement of the receptacle assembly in the vertical direction.
It should be understood that the particular positive restraining
means illustrated in FIGS. 6 through 8 are only illustrative. Any
number of well known equivalent means could be substituted for the
rib and slot retaining means shown.
The afore-described cassette album and library storage apparatus
can easily be modified so that the housing assembly 16 functions as
a cover as well as a magazine assembly. Thus in FIG. 9, each of the
individual covers 16 are provided with a dove-tailed slot 70 along
one side thereof, and a corresponding dove-tailed rib 72 along the
other. Thus, if it is desired to assemble a library of cassette
receptacle assemblies, all that is necessary is that the individual
assemblies be slid into place along their respective dove-tailed
slots and ribs. Alternately, only dove-tailed slots can be provided
along the side walls 36 of the housing assemblies 16 and then a
third or combining member having a double dove-tailed cross-section
could be inserted to hold the receptacles together.
As another modification (not shown), a plurality of housing
assemblies 16 are formed in a composite and integral manner to form
the magazine 52. In this manner, a plurality of cassettes are
stored in a single housing. Of course, in this embodiment, the
individual receptacle assemblies cannot be removed as in the
embodiment of FIG. 6.
Another embodiment of the invention is illustrated in FIGS. 10
through 15. The cassette 12 is inserted within a cassette holder
member 80 of a different design than the holder 14 of FIG. 1.
Holder 80 includes a bottom wall 82 and a perpendicularly extending
front wall 84. Front wall 84 includes a slot 86 for receiving a
guide rib 44 formed on the cassette 12. Raised portions 90 also aid
in guiding the cassette 12 within the holder 80 and also helps to
prevent the cassette 12 from falling out of the holder 80.
At the opposite end of the bottom wall 82 from the front wall 84 is
support or restraining means such as the perpendicular support
member 92. Support member 92 acts to hold the cassette 12 within
the holder member 80 and is rotated to the open position as shown
in FIG. 10.
The holder 80 is rotatably moved about a hinge 94 in and out of an
album cover 96. The cover member 96 includes side walls 98 which,
in combination with the holder member 80, define a generally
rectangular volume conforming to the size and shape of the cassette
12, when the holder 80 is rotated to the closed position.
As shown in FIGS. 10 and 11 the albums are adaptable for storage in
a library arrangement. A support member 100 has a plurality of ribs
or guides 102 thereon. A corresponding female or receiving slot 104
is formed in the back panel 106 of the cover member 96. As can be
seen in FIG. 14 the slot 104 has a dove-tail cross-sectional
configuration. This allows the album to be positively held to the
support member 100 when the album is inserted therein as shown in
FIG. 11. In this arrangement, there is no way for the album to be
dislodged when a cassette holder is rotated to the position in FIG.
10.
In particular the combination of rib 102 and slot 104 is oriented
in a direction perpendicular to the direction of force necessary to
rotate the cassette holder 80 out of the library.
The embodiment of FIGS. 10 through 15 can be implemented by use of
a flexible type plastic such as polypropylene. The advantage of
such a plastic is that it is flexible and cheaper in construction.
Another advantage, is the simplified means by which the hinge 94
can be constructed. FIG. 15 shows the unitary construction of the
hinge 94. Where it is desired to construct the hinge 94, the
thickness of the wall at that point is reduced to a smaller width
110. This smaller width gives added flexibility to that point of
the structure thereby serving as a hinge for the cover member
80.
Another embodiment of the invention is illustrated in FIGS. 16
through 18. Album 120 includes a rotatable cover member 122 and a
cassette holder 124. The holder 124 includes slots 126 along one
end thereof for use when inserted within the library 56 shown in
FIG. 6.
Means are provided for conveying or ejecting a cassette 12 from
within the holder 124 when the cover member 122 is rotated to the
open position. One means for accomplishing this is illustrated in
FIGS. 17 and 18. Here a leaf spring 128 is attached at 129 to one
end to the back wall of the holder 124. The leaf spring is
compressed when the cassette 12 is placed within the member 124 and
the cover 122 is rotated to enclose and confine the cassette. When
the door or cover 122 is opened, the spring 128 forces the cassette
12 outwardly of the holder 124 as well as out of the library
volume, if the album 120 is stored within a library such as the one
of FIG. 6.
While all the above embodiments of the improved cassette album of
the invention are suitable for storage in, for example, a drawer
(without the use of a library storage apparatus) the last
embodiment is particularly well suited for that purpose since the
cover 122 requires less room to be moved to the open position. This
assures, of course, that the album is stored with the cover 122
facing upwards.
Another embodiment 130 of the library storage apparatus is
illustrated in FIGS. 19 and 20. Guide flanges 132 mounted to the
back wall of the library storage apparatus provides positive
restraining means for holding the cassette cover in place while the
cassette holder is moved to the open position. The flanges engage
the guide portions 126 in the cassette cover.
The library storage apparatus 130 is provided with a back flange
134 which can be slidably inserted within a mounting bracket 136.
The mounting bracket 136 can, for example, be affixed to any
suitable surface, such as a wall.
The library storage apparatus of the present invention is not
intended to be limited to removing the cassette cartridge in a
particular direction. Thus while in the embodiment of FIG. 19 one
would usually mount the library storage apparatus 130 so as to
allow vertical removal of the cartridge therefrom. FIG. 21
illustrates that the library storage apparatus 130 can also be
mounted for horizontal access.
The afore-described cassette receptacle assembly and library
storage apparatus provides a simple but efficient way of storing
one or more cassettes. The aforesaid invention permits the user to
withdraw a single cassette from a cassette library without
disturbing or having to remove other cassettes. Further, as a
result of the inter-relationship of the cassette storage receptacle
and the library storage apparatus it is possible to remove an
individual cassette album without having to remove the cassette
itself, thereby providing the user with a convenient way of
transporting only a single cassette.
