CONVERTIBLE SATCHEL
Abstract
A satchel is made convertible for selective carrying by hand, in
the manner of a handgrip or valise, or by supporting it on the back
and shoulders in the manner of a knapsack. A substantially rigid
frame supports the container or bag portion and has a manually
engageable handle and a shoulder strap harness attached thereto. A
panel or flap in the covering material of the satchel conceals the
strap harness when carrying by hand is intended, and this flap or
panel rolls up to provide a resilient cushion engageable with the
back of the user when shoulder carrying is intended, the cushion
serving to space the lower portion of the frame away from the back
of the user. The panel is closed by a slide fastener and straps and
buckles are provided to keep the panel in its rolled position. The
frame may be made integrally with, or attachable to, the container
portion.

Description
BACKGROUND OF THE INVENTION
This invention relates to a CONVERTIBLE SATCHEL adapted to be
carried in the hand in the manner of a conventional suitcase or
valise, or carried upon the back in the manner of a knapsack.
Conventional suitcases or valises have a manually engageable
carrying handle on their upper edge. This construction is
convenient for carrying the bag short distances, because the hand
of the user can readily grasp and let go of the carrying handle.
However, this mode of use necessarily involves tying up the use of
the carrying hand, and the uneven distribution of forces results in
the user continually stopping to change the bag from one hand to
the other.
In an attempt to overcome the recited problems relating to
transportation over a considerable distance, shoulder straps have
been provided, by means of which the bag can be carried on the back
and shoulders of the user. This solution has not proven to be
widely acceptable because of two principle problems. In the first
place, the appearance of the bag is not enhanced by the addition of
the shoulder straps, and bag is not supported in a comfortable
position when worn as a knapsack.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a
convertible satchel for selective carrying in the hand or on the
back of the user and in which the back carrying straps are
concealed from view when not in use so as to provide a
hand-supported bag of conventional appearance.
Another object of the invention is to provide a convertible satchel
which is formed and portioned for support on the shoulders and back
of the user in a manner affording maximum comfort and unrestricted
freedom of movement.
A further object of the invention is to provide a convertible
satchel in which the back carrying straps are selectively
concealable behind a panel, and in which the panel cooperates with
the straps to provide optimum comfort to the user.
Further objects and advantages of the invention will be apparent as
the specification progresses and the new and useful features of the
convertible satchel will be more fully defined in the claims
attached hereto.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawing in greater detail, the convertible satchel
of the present invention basically includes a container bag portion
11 having a manually engageable handle or handles 12, a
substantially rigid frame 13 operatively connected to the container
bag portion 11, suspension means 14 on the frame 13 formed for
supporting the frame and container bag portion across the back and
shoulders of a user (not shown), and a panel 16 of resilient
flexible material selectively mountable on the satchel in an
extended position, in covering relation to the suspension means 14,
and a retracted position (best seen in FIGS. 2 and 4) providing a
resilient cushion 15 between the frame 13 and the back (not shown)
of a person carrying the satchel on his back and shoulders.
The container bag portion 11 may be made from any of a number of
suitable materials normally used in the construction of satchels,
suitcases, etc. Preferably, the covering material is flexible and
may conveniently consist of canvas, fabric or other suitable
flexible sheet material. The container bag portion 11 here utilizes
a conventional slide fastener closure 17 and is equipped with a
pair of manual carrying handles 12. Panel 16 comprises a generally
rectangular flap 18 of covering material which may be separated
from the surrounding portion of the covering material, on three
sides, by a slide fastener or zipper 19.
As may best be seen in FIG. 3 of the drawing, the frame 13 is
secured to the bag 11, to lie behind the panel 16 when the latter
is closed. The frame 13 is preferably of substantially rigid
construction in order to serve both as a mount for the suspension
means 14 and as a stiffener for the bag 11. Frame 13 may be made of
any suitable material having the required properties of strength,
substantial rigidity and light weight, such as the sheet plywood
diaphragm illustrated in the drawings. Frame 13 is separated from
the interior of the bag 11 by an interposed sheet of fabric 21, see
FIG. 3.
The suspension means 14 here includes a pair of adjustable straps
22 and 23 adapted to fit over and around the shoulders of the user
(not shown). These straps are preferably formed of webbing and are
secured at one end to the frame 13 by reducing the width of such
ends, passing them through grommeted apertures 24 and 26 in the
frame 13 and releasably securing them in place by means of a buckle
27. The free ends of the straps 22 and 23 are folded back through
buckles 28 and 29 to form adjustable loops carrying snap hooks 31
and 32, by means of which the straps may be demountably attached to
anchorages formed by spring wire loops 33 and 34 secured in
grommeted apertures 36 and 37 in the frame 13. Buckles 28 and 29
permit convenient adjustment of the length of the shoulder straps
22 and 23.
As may be seen from FIGS. 1 and 3 of the drawing, when the case is
to be carried in the usual way, e.g., by hand, the frame 13 and
suspension means 14 are completely concealed behind the closed
panel 16 so that the presence of the frame and suspension means is
not noticeable, and the satchel has the appearance of a
conventional handbag. However, when the device is to be carried as
a knapsack on a person's back, panel 16 is unfastened and rolled
down to expose the suspension means 14.
As shown in FIGS. 2 and 4, the rolled panel is secured in rolled
form near the bottom of the frame 13 by straps 38 secured at one
end to frame 13 and having snap fasteners 39 at their other ends.
The straps 22 and 23 are then looped around the shoulders of the
person who is to carry the device on his back, and the cushion
provided by the rolled panel 16 is interposed between the lower
portion of frame 13 and the back of the user to support the case in
the most comfortable carrying position. Preferably, panel 16 is
provided with a layer 41 of resilient material to increase the bulk
and resilient softness of the rolled-up panel 15. The layer 41 may
conveniently consist of a resilient and light weight foamed rubber
or plastic.
When it is desired to reconvert the device for manual carrying, the
lower ends of the straps 38 are unsnapped from the base of the
container, and the panel 16 is unrolled and is refastened in its
extended position by means of the slide fastener 19.
It should be understood that the convertible satchel of the present
invention can be made of unitary construction in the manner
illustrated in the drawing and described above, and that the
harness arrangement comprising the frame 13 suspension 14 and panel
16 may also be manufactured and sold as a separate unit securable
by suitable means, such as a slide fastener, or snap fasteners, to
an existing case or other portable container. In the latter event,
the fabric sheet 21 is not normally required, since the frame 13
will be secured to the outside surface of the case. The panel 16
may be secured directly to the frame 13 instead of being secured to
or formed integrally with the container.
From the foregoing it will be seen that the convertible satchel of
the present invention is adapted for ready and rapid conversion for
carrying on a person's back or in his hand, the conversion being
effected without disturbing the contents of the case. The harness
arrangement is light in weight and adds little to the spatial
requirements of the bag, and is completely hidden from view when
the bag is to be carried by hand.
