Description
BACKGROUND OF THE INVENTION
This invention relates generally to carrying cases and more
particularly to a novel reversible carrying case with at least two
sections adapted to be carried like an attache case and turn
relative to one another on a hinge inside out along corresponding
sides to expose inside structure adapted for a variety of uses.
At the present time there are no known products in the nature of a
carrying case available in which a person may satisfactorily write
when seated in a chair with the device supported on the lap of the
person. There are many possible applications for such a device
including use during travel, when in the office, in the field, or
at home in a comfortable chair. While some attempt has been made to
utilize an inside of an attache type case for such writing
purposes, no known attache type cases have been entirely
satisfactory. Moreover, there is no known attache case available
which affords sufficient flexibility to serve more than one purpose
when turned inside out. Previous attempts to provide reversible
carrying cases such as that shown in U.S. Pat. No. 2,443,182 have
soft bag-like sections and reverse the sections to more readily
render accessible the contents contained therein but do not provide
enough versatility in the construction thereof to make the sections
useful for several purposes.
Accordingly, it is an object of this invention to provide a novel
carrying case which is reversible inside out making it suitable for
a variety of uses including for use as a miniature desk, lecturn,
display board, projector screen, light table and the like.
Another object of this invention is to provide a novel reversible
carrying case characterized by being made of two sections each
having a smooth, hard, planar, inner utility surface extending
substantially the full extent of the inside of the associated
section.
Yet another object of this invention is to provide a novel case in
which additional sections may be readily added and yet will fold
into a sandwiched or stacked relation for carrying purposes.
Still a further object of this invention is to provide a novel
carrying case principally characterized by having two sections
hinged to swing a full revolution relative to one another and be
disposed in a sandwiched relation so that inner smooth surfaces may
be disposed at selected angular positions and when the sections are
fully inside out and parallel to one another serves, inter alia, as
a miniature writing desk positioned on the lap for use.
SUMMARY OF THE INVENTION
In accordance with the present invention in a preferred embodiment
shown there is provided at least two sections with each having a
smooth, planar, hard, inner utility surface extending the full
extent of the inside of the associated section and at least one
section having an inner storage compartment. The sections are
hinged together for swinging movement to turn completely inside out
to expose the inner utility surfaces for a variety of uses
including for use as a miniature desk, a lecturn, projection
screen, light board, display board and the like. The sections are
releasably fastened together in the closed position and each have a
retractable handle for carrying purposes. Each section has an
inside panel portion hingedly secured thereto to provide access
into the inner compartment and the composition of the inside panel
portion is varied for different purposes. The panel portions may be
constructed of Plexiglass and be transparent with a removable
projector screen surface on the inner back side thereof for use as
a projector screen or the panel portion may be translucent with a
light reflecting surface on the inner back side of the section with
a light source in the compartment for use as a light table, the
sections also being particularly suited for display and/or writing
purposes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The carrying case shown in FIGS. 1 through 10 of the drawings in
general comprises two case sections designated A and B hingedly
connected along adjacent corresponding side edges by a universal
hinge generally designated by numeral 13 which permits each of the
sections to swing through a full revolution between a closed
position shown in FIG. 1 and an inverted inside-out open position
shown in FIG. 3. The sections are releasably fastened together in
the closed position by suitable cooperating male and female
fastening portions 14 and 15 located at the center along the inside
upper edge of sections A and B, respectively. Each section A and B
has a retractable handle 16 and 17, respectively, secured at the
upper side to permit the case to be hand carried.
The carrying case shown has a removable flexible side strap 18
releasably secured along each side of each section. Each strap has
a plurality of eyelets 19 at spaced intervals along the length
thereof secured at the ends by screw fasteners 20 at opposite ends
thereof to hold the sections at a selected angular position
relative to one another. The side straps 18 are preferably made of
a flexible fabric such as woven nylon with the eyelets 19 located
at each end and at spaced intervals between the ends. The screw
fasteners 20 extend through the eyelets and thread into apertures
in the side channel members. When not in use, the straps are
carried within each side channel member and held in place by the
fasteners 20 which again thread into apertures in the side channel
members.
The sections A and B are held by the side straps 18 at various
angular dispositions. For example, with section B turned
270.degree. relative to section A from the closed position, the
case is usable as a projector screen as shown in FIG. 4. With case
section A turned about 320.degree. relative to case section B, the
case is usable as a lecturn as shown in FIG. 5. Moreover, the case
may be opened only with one case section pivoted 180.degree. from
the closed position and the inner surfaces of the case sections
form a coplanar surface as shown in FIG. 6 and described more fully
hereinafter.
In the illustrative embodiment shown in FIGS. 1 through 10, each of
the sections A and B shown are generally of a corresponding size
and shape and construction so that a description of one generally
applies to both with some variations as will be described in detail
hereinafter. Section A includes opposed upper and lower channel
members 21 and 22, respectively, and opposed end channel members 23
and 24 connected at the corners to members 21 and 22 in an open
framework together with a thin flat outer panel 25 and a thin flat
inner panel 26 mounted on the framework to form the inner storage
compartment 27 therein with the straight outer edges of the panels
being flush with the outer edges of the legs of the associated
channel members so that the inside surfaces extend continuously
through substantially the full extent of the inside of each
section.
Each lower channel member has a similar transverse cross section
and with reference to member 22 comprises an intermediate web 22a,
an outer leg 22b, and an inner leg 22c which is shorter than the
outer leg to at least allow for the thickness of the hinge straps
described hereinafter.
The outer panel 25 is fixedly secured to the framework as with an
adhesive, rivets or the like and the inner panel 26 is pivotally
mounted on the lower channel member 22 with a suitable inside hinge
represented at 28 to permit the inner panel 25 to swing away from
the framework and provide access into the inner storage compartment
27.
A suitable light source 29 is mounted in the compartment 27 which
may be battery powered or powered by conventional AC electric line
power in a suitable electric cord. The inside surface of the outer
panel 25 designated 25a is a light reflector surface and the panel
26 shown is a translucent Plexiglass sheet or the like making
section A suitable for use as a light table. This light reflector
surface may be provided as a coating on the inside of the panel 26
or as a separate insert sheet. In its use as a light table an
object such as microfilm, slides, transparencies and microforms may
be placed on the top or outer surface of panel 26 and edited.
The outer surface of outer panel 25 is a wear surface of high wear
material such as vinyl plastic which may be of a selected color.
The Plexiglass with a smooth, hard outer surface which is
particularly suited for use as a writing surface or the like when
the sections A and B are turned inside out as shown in FIG. 3.
Likewise, section B includes upper and lower channel members 31 and
32, respectively, and a pair of opposed end channel members 33 and
34 connected to members 31 and 32 to form an open framework with an
outer panel 35 and an inner panel 36 mounted on the framework to
form an inner storage compartment 37. The inner panel 36 is
pivotally mounted to the lower channel member 33 with a suitable
inside hinge 38 to swing away from the framework to provide access
into the storage compartment 37. A removable reversible sheet 35a
is mounted in compartment 37. Sheet 35a may be made of aluminum
with one side painted white to form a screen projector surface for
a movie projector or the like with the other side painted black to
display photographs or the like.
The handles 16 and 17 are of a similar construction and as best
seen in FIG. 7 with specific reference to section A handle 16
comprises a pliable strap 40 inserted into a pair of spaced apart
rigid loops 41 and 42 in the outer channel and affixed thereto at
opposite ends so that the handle may be extended for carrying as
shown and be retracted wherein it lays along the inside of the
channel and does not protrude therefrom as shown in dashed lines at
40a.
For the hinge 13, joining the sections together, each of the lower
channel members 22 and 32 of sections A and B, respectively, have a
plurality of elongated slots arranged in a staggered or alternating
order. Channel member 22 has one group of slots designated 71 being
formed in one side of the web and another group of slots designated
72 formed in the opposite side of the web with each slot of the
first group 71 offset a slot length from a slot in the second group
72. In turn, lower channel member 32 has one group of slots 51 in
one side of the web and another group of slots 52 formed in the
other opposite side of the web. When the lower channel members are
in an aligned position facing one another as shown in FIG. 9, the
one group of straps 53 extend diagonally from one side of the
channel member to the other side of the opposite channel member
while the other group of straps 54 extend diagonally from the other
side of channel member to the opposite side of the other channel
member to extend from diagonally opposite points on said sections
so that the two groups of straps 53 and 54 cross or intersect at
their midpoints between the lower channel members. This strap
arrangement allows each section to swing through a full revolution
relative to the other section.
With the two lower channel members of the two sections in a
juxtaposed relation as shown in FIG. 10, a group of hinge straps 53
extend along the back side of the web through a slot, then over the
adjacent leg portion and down through a corresponding slot in the
other channel member. Each portions of the straps extend along the
back of the web and are shown as fixedly secured thereto as with an
adhesive as represented at 56.
When used as a lecturn as shown in FIG. 5, a socket 61 at each
corner of the framework receives a male headed portion 62a formed
on a detachable sheet support member 62 suited for supporting a
sheet material on one inner surface thereof as with a conventional
lecturn. The inner panel 26 has notched corner portions 26a to
receive the sockets 61 as well as a center notch 26b to receive
fastener portion 15. Moreover, there is provided a suitable lamp
attachment 63 releasably mounted on the lower channel member 22 to
light sheet material or script supported on the lecturn in the
channel of member 62. The lamp attachment 63 may be powered by a
conventional DC battery power pack or an AC line power and the lamp
attachment will include a bulb and outer shade portion with a
suitable flexible neck to direct the light onto the utility surface
of panel 26.
When used as a vertical display as shown in FIG. 6, the sections A
and B are held end to end abutting one another at adjacent side
edges in a flush relation by rigid side brackets 18a which insert
into the side channel members and are secured in place by the screw
type fasteners 20 which extend into apertures in the web of the
side channel members. A pair of feet members 18b and 18c of a right
angle shape press fit into the channels against one another and
have lower portions which project outwardly in opposite directions
to support the planar configuration upright as shown.
In another form of the present invention shown in FIG. 11 there is
provided a pair of intermediate sections designated C and D
sandwiched between case sections A and B like an accordion using
the hinge structure 13 at connected ends so that the sections fold
like an accordion between a closed sandwiched position wherein they
may be carried like an attache case and an open position in which
the outer surfaces of corresponding surfaces are in a common plane.
In this form, the intermediate sections preferably have both panels
made of a transparent material which make is particularly suitable
for use as a display for collections of stamps and the like.
From the foregoing it is readily apparent that the present
invention utilizing a thin sheet of Plexiglass for the inside
panels advantageously provides a clean smooth, durable surface for
writing purposes and then by properly sizing the case sections and
making the inner channels from light weight material such as
aluminum that will be a relatively light weight and will readily
fit on the lap of a person when seated in a chair. The recesses
permit the storage of accessory items such as the side straps and
also allow the attachment of sheets to the panels by means of a
clip or the like. The straight side edges with only slightly
rounded corners make it especially suited for use as for example a
draftsman wherein a T-square may be placed along one side to draw
straight lines. Further the device may be used by stamp collectors
wherein the stamp displays may be held under the Plexiglass sheets
and particularly this is true for the form shown in FIG. 11.
It is also apparent that for some applications only one of the
sections need have an inner utility surface and the other may be
more in the form of a cover sheet to protect the utility surface
when not in use. For some applications it may be desirable to have
the upper edge where the handles are mounted closed or smooth as
distinguishable from the recessed structure shown.
Finally, a device utilizing features of the present invention may
be readily used at home and the office meetings, while traveling on
a plane, train or car and practically any time or any place and
allows many uses of the same structural arrangement for different
purposes.
Although the present invention has been described with a certain
degree of particularity, it is understood that the present
disclosure has been made by way of example, and that details of
structure may be made without departing from the spirit
thereof.
