United States Patent 3,123,853 CARRYING CASE Frank A. Hoifman, James K. Baker, and Melvin L. Buchanan, all of Columbus, Ind, assignors to Arvin Industries, Inc, tlolumhns, Ind, a corporation of Indiana Filed Oct. 20, 1961, Ser. No. 146,488 a Claims. (Cl. 190-41) This invention relates to a carrying case, and has for its object the provision of a carrying case of attractive appearance which can be easily and economically manufactured largely from inexpensive sheet-metal, which can be carried by carrying means easily adjustable for use as a hand grip and a shoulder strap, which will be sturdy and durable in use, and which can be easily opened for ready access to the contents carried therein and releasably locked in closed position.

In carrying out the invention in its preferred form, there is provided a case having interconnected and opposed front and rear, top and bottom, and side walls, said top wall being pivotally mounted on the case for swinging movement between open and closed positions and provided with lock means for releasably locking it in its closed position. A pair of opposed guides are mounted within the case and are desirably provided with portions generally parallel with, and spaced closely adjacent to, the case side walls to form therewith a pair of opposed elongated passages for the reception of an elongated carrying strap. Said strap is slidably carried in said passages with its intermediate portion projecting out wardly through openings in the front case wall and its ends projecting outwardly through openings in the rear case wall and releasably connected thereto. In this manner, the strap is adjustable between a retracted position in which its ends are connected to the rear case wall and its intermediate portion forms a hand grip and an extended position in which its intermediate portion forms a shoulder strap and its ends are releasably retained in said passages.

The embodiment of our invention illustrated in FIGS. 1-9 comprises a pair of sheet-metal shells it? and 12 operatively interconnected to each other and to a pair of side panels 14. As shown, the shell 12 is bent in a manner to form the case bottom wall 16, the lower portion 18 of the case front wall, the case rear wall 20, and the rearwardly disposed portion 22 of the case top wall. As shown in FIG. 5, the end of the shell portion 18 is provided with an inwardly rolled bead 23, and the rearwardly disposed portion 22 of the case top wall is provided with an inwardly projecting flange 24.

The lateral edges of the shell 12 are offset, as at 26, and are bindingly retained in grooves formed in the inwardly presented faces of the side panels 14%, which side panels constitute the side walls of the case. For reasons that will become more apparent hereinafter, the portion 18 of the shell 12 is provided with openings 28 adjacent each of its lateral edges and the side panels 14 have hoods 30 extending laterally inwardly over said openings. The rear wall portion 20 of the shell 12 is also provided with openings 32 adjacent each of its lateral edges, and said rear wall portion is deformed inwardly to provide a channel 34 extending transversely across the rear case wall between the openings 32.

As shown in FIG. 5, the shell it) is bent to form the forward portion 35 of the top case wall, the upper portion 36 of the front case wall, and a pair of downwardly extending side stretches 37. Conveniently, said upper front wall portion 36 and the side stretches 37 are provided with inwardly rolled beads 38. A transversely extending rolled bead 4th is formed in the shell portion 35 at its rearward edge and carries a transversely extending rod 42 which projects outwardly from the lateral edges of the shell It) for reception in aligned openings formed in the inwardly presented faces of the side panels 14 to swingably mount the shell 11 on the case and permit said shell to be swung between an open position generally normal to the bottom case Wall 16 and a closed position in which the shell beads 38 and 23 are in abutting relation. Conveniently, each of the side panels 14 is provided with an inwardly projecting shoulder 44 against which the beads 33 on the side stretches 37 of the shell 10 are received when said shell is in its closed position. A latch mechanism 46 is mounted on the front wall portion 36 of the shell 10 and is receivable under the head 23 on the shell portion 18 for releasably locking the shells It) and 12 in case-closed position.

As is best illustrated in FIGS. 5-7, a pair of guides 48, conveniently formed as sheet-metal stampings, are mounted within the extent of the shell 12. Each of said guides comprises an outwardly open channel 50 having pairs of outwardly extending ears 52 which are rigidly connected to the adjacent side panels 14. The guides 48 are curved at their ends and are rigidly fastened, as at 49, to the portions 18 and 20 of the shell 12 lateraliy inwardly from the openings 28 and 32, respectively. As shown in FIG. 7, the webs of the guide channels Sit are generally parallel with, and spaced closely adjacent to, the inwardly presented faces of the side panels 14 to form therewith elongated passages 51 extending along the opposite sides of the case, the hoods 3t) forming passage extensions outside the extent of the front case wall. Conveniently, each of the channels 50 is offset outwardly, as at 53, to form a stricture in each of the passages 51.

An elongated carrying strap 54 is carried in the passages 51 and is adjustable between a retracted hand grip position and an extended shoulder strap position. In its retracted hand grip position, the strap 54 is carried in the passages 51 with its ends projecting through the openings 32 in the shell 12 and rigidly secured to the rear case wall 29, as by cooperative fastening snaps 56 and 58 mounted on said rear Wall and strap ends, respectively. In this retracted position, the intermediate portion of said strap extends forwardly through the openings 23 between the passages defined by the side panel hoods 3t) and the portion 13 of the shell 12 in a position such that it may be gripped in the manner of a conventional hand grip. The strap is adjustable into an extended shoulder strap position in which its intermediate portion is disposed well away from the front case wall. To accomplish such extension, the snaps 58 on the strap 54 are merely released from their cooperative snaps 56, and the strap is pulled away from the front case wall with its ends sliding in the passages 51. As shown in FIG. 7, the snaps 58 on the strap 54 project outwardly from said strap and thus abut the passage strictures 53 to prevent said strap from pulling completely out of the case. To retract the strap it is merely necessary to slide the strap ends in the passages 51 toward the rear case wall 2%, and the curved portions of the guides will guide the ends of the strap back outwardly through the openings 32 in order that their snaps 58 may be received in the snaps 56 on the shell 12. The inwardly extending channel 34 formed in the rear case wall 20 permits the strap 54, in its retracted position, to be carried generally inwardly from the plane of said rear wall in order that the case may be set in a generally upright position. Conveniently, outwardly projecting feet 60 may also be mounted in said rear wall 29 to further enhance the stability of the case when it is in such an upright position.

The modified embodiment of our case illustrated in FIGS. -l7 also comprises a pair of sheet-metal shells 10' and 12 operatively interconnected to each other and to a pair of side panels 14'. As shown in FIG. 14, the shell 12 is bent in a manner to form the bottom case wall 16', the lower portion 18 of the front case wall, the rear case wall 20, and the rearwardly disposed portion 22 of the top case wall. The transversely extending edge of the shell portion 18' is provided with an inwardly rolled head 23 extending thereacross.

As shown in the drawings, each of the side panels 14' has an outwardly projecting finger 64 within the extent of the shell 12, and the lateral edges of said shell are crimped over said finger, as at 66, to rigidly connect said shell side panels 14. A pair of openings 28 are formed in the shell portion 18 laterally inwardly from the panels 14', and a pair of hoods 30 are mounted on the shell portion 18' to extend over said openings. A pair of openings 32 are also formed in the rear case wall 20 adjacent the side panels 14, and said rear case Wall is offset inwardly, as at 34', between the openings 32 to define an inwardly offset channel extending transversely across the rear case wall.

As is best shown in FIG. 14, the shell 10 is bent to form a forward top wall portion 35' continuous with a downwardly bent portion 36' forming the top portion of the front case wall, the shell portion 36 having a transversely extending inwardly rolled bead 38 adapted to abut the bead 23' when the case is in its closed position. The rear edge of the shell portion 35' is rolled, as at 40', for the reception of a transversely extending rod 42. having its ends swingably carried in a pair of rolled flanges 68 formed in the forward edge of the portion 22 of the shell 12' and disposed in axial alignment with the roll 40' formed in the shell 10'. In this manner, the shell 10' is swingable between a case-open position in which it is generally normal to the bottom case wall 16' and a case closed position in which its head 38' abuts the bead 23' on the shell 12. As shown in FIG. 12, each of the side panels 14- has an inwardly rolled bead within the extent of the shell It! abutting the inner face of said shell when the case is closed, and the lateral edges of said shell are provided with inwardly rolled beads 72 which abut the outer face of the side panels 14 when the case is closed.

Mounted on the portions 18 and 20 of the shell 12' adjacent each of the lateral edges are a pair of guides 48' having their ends curved inwardly and mounted on the front and rear portions 18 and 20' of said shell. Each of the guides 48' has an outwardly open channel 50' Whose web is generally parallel with, and spaced closely adjacent to, the inwardly presented face of the adjacent side panel 14 whereby the pair of guides form elongated passages 51' extending along the opposite sides of the case. The channels 50 are outwardly oflset, as at 53, adjacent the case front wall to form strictures in the passages 51.

An elongated strap 54' is carried in the passages 51 and is adjustable between a retracted hand grip position and an extended shoulder strap position. In its retracted hand grip position, the strap 54 is carried in the passages 51 with its ends projecting through the openings 32 in the shell 12 and rigidly secured together and to the rear Wall of said shell. As shown, one end of the strap 54' is provided with a snap 74 lockingly engageable with a snap 72 mounted on the rear case wall 20'. The end of the strap 54' provided with the snap 74 is also provided with a snap 75 l-ockingly engageable with a snap 76 mounted on the opposite end of said strap. Thus, the snap 74 may be locked with the snap 72 and the snap '76 may be fastened to the snap 75 to releasably connect the strap 54' to the case in a retracted position with its intermediate portion extending forwardly through the slots 28 between the hoods 30 and the portion 13 of the shell 12 in a position such that said intermediate portion may be gripped in the manner of a conventional hand grip. By disconnecting the snaps 74 and 72 and 76 and 75, the strap 54' may be slid outwardly in the passages 51 into its extended shoulder strap position in which the intermediate portion of said strap is well spaced from the front case wall, the snaps 74 and 76 engaging the offsets 53 and preventing the strap from pulling out of the case. Conversely, to retract the strap to its hand grip position, the ends of the strap are merely slid in the passages 51' to enable the snaps 74 and 76 to be fastened to the corresponding snaps 72 and 75, respectively.
