lA/l/E/VTOR CONVERTIBLE SA'ICHEL BACKGROUND OF THE INVENTION This invention relates to a CONVERTIBLEv 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 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.
BRIEF DESCRIPTION OF THE DRAWINGS The preferred form of the invention is illustrated in the accom panying drawing forming part of this specification, in which:
FIG. I is a side perspective view of a convertible satchel constructed in accordance with the present invention, the parts of the satchel being shown in operative position for carrying by hand;
FIG. 2 is a view similar to that of FIG. 1 but showing the parts in operative position for carrying of the satchel upon the back and shoulder of the user;
FIG. 3 is a vertical cross-sectional view on an enlarged scale taken substantially on the plane of line 3-3 of FIG. I; and
FIG. 4 is, a fragmentary cross-sectional view on an enlarged scale taken substantially on the plane of line 4-4 of FIG. 2.
While only the preferred form of the invention is shown, it should be understood that various changes or modifications may be made within the scope of the claims attached hereto without departing from the spirit of the invention.
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 I2, 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 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 l9.
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 1 l by an interposed sheet offabn'c 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 fonned 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 dcmountably 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 persons 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.
