LUGGAGE CASE SUCH AS HAT BOX EmmcttI-I. Heitler, Denver, (1010., assignor to Shwayder Bros, Inc., Denver, (1010., a corporation of Colorado Application January '27, 1955., Serial No. 484,335
19 Claims. (Cl. 190-48) been provided with a backing plate or reinforcement to which a hinge or hinges connecting the two sections together are attached. Also, a reinforcement for the remaining edges of one section may be adapted to be received by an L-shaped reinforcement for the corresponding edges of the opposite section. The two sections may be held in closed position by various types of locks, bolts, draw bolts and the like. However, the principal structural element of such luggage cases is the leather, with the parts attached to the abutting edges of the sections being merely reinforcement for the leather. In other types of luggage cases, the principal load resisting elements of the two interfitting sections have been made from. panels ;of plywood or the like, covered withfabric or plastic, with reinforcing plates, hinges, cooperating edge reinforcements, hardware and similar parts being attached thereto in a manner similar to the leather case described above. Whilesturdy .in construction and highly resistant to wear and therefore quite serviceable and highly popular, since many millions have been sold, such luggage cases tend to bev heavier than desired. Also, the two sections of the case have been made from metal drawn to shape, so that there are no abutting edges or joints at the corners, but the weight is still unduly great. Numerous improvements have of course been made in the construction of luggage cases, but the essential load a bearing elements have always comprised the material of which the case sections are made. strips have been added at the corners and at various points, particularly on the outside edges, which contribute considerably tothe strength and durability of, the case. Nevertheless, with the principal load bearing elements being the sides, bottomsandends of the case sections, the walls of the sections are necessarily sufiiciently heavy to Withstand the load i posed thereon so that the ultimate in light-Weight luggage cases has not been achieved. I
Among the objects of the present invention are to provide a novel type of construction for luggage cases; to provide such a construction which is particularly applicable to hat boxes, but certain features of which are also applicable to other types of luggage cases; to rprovide such a construction in which the principal load bearing elements are comparatively light in weight; to provide such a construction in whi h the bottom, sides and ends ,of the sections are ,not reguir ed to resist the load tobe placed thereon and therefore may be lighter in weight than previusly; to provide a novcl'hat box; to provide such i at 2,829,745 Ratented-Apr. 8, 1958 l' ce box which :is light-in weight, yet hassufficient resistance to forces which would tend to deformthe same; to provide such ahat box comprising two sections which fit together easily and provide :a maximum of strength when so fitted together; 1o;.provide various novel parts 'for a luggage case, including theload bearing parts, the parts of the sections which'interfit and the manner in which the remainderof thesections are attached thereto; to provide a novelhandle-gfora hat -.box or the like; and to provide such a hat box and other luggage cases embodying certain principles f construction thereof, which are relatively economical to manurtacture.

'As,.illustrated in Figs. l-3, a hat box constructed in accordance with thisqinventionmw comprise a body sec- 'tion B and a lid section ,L, each having a flat bottom so that with thesections closed, as in Fig. l, the fiat bottom will form a base :on whichthe hat box may conveniently For access to the interior of the hat. box, it may be placed with the body 'B laid on a support so that the lid L may be raised, as to the position of Fig. 2. The two sections may be connected ajtthe bottom by a'hinge1'0, as in Fig. 3. In closed position, the sctionsmay be held together by a ,pair of draw bolts 11 and a lock 12, .the draw bolts 11 being conveniently positioned about apart, i. e., the hinge and draw bolts thus'beiugplaced substantially equidistantly around the periphery'ofthe case. The lock .12 is preferablydisposed oppositeithe hinge 10 to lock the case in closed position, when access by unauthorized persons is to be denied. During use when closed, the case is most conveniently placed on the fiat bottom, as in the position of Fig. l, and is conveniently carried by means of the loop handle The interior of the hat box may be provided with a suitable lining-13 for the lid L and a lining 13' for the body B, formed of rayon or..other suita'ble' fabric' material. In addition, pockets 14 maybe attached to the underside of the lid L, while additional pockets ld'may be attached around the sides of the body B. The pockets 14 and 14' may be conventional shirred material, similar to the lining, :provided with covered elastic along the :upper edges. Also, an apron 15 may conmeet the two sections oftheaoase, at the hinge, to prevent articles being caught between the sections as the case is closed.
In accordance with thiswinvention, the principal load bearing members of a luggage case, comprise a pair of cooperating strips, such as a tongue strip T extending around the entire peripheral edge of one section, such as body B, and a groove strip G extending around the entire periphery of the other section, such as the lid L. These tongue and groove strips interfit with the case in closed position to form a'stableframe. adapted to resist the load and stresses placed on the case, which will normally be imposed with the case in the upright position of Fig. l. The tongue and groove strips are identical in contour such as that shown in Fig.6 for tongue strip T, i
being extruded or produced in any other suitable mannerfrom aluminum alloy or other light-weight metal and formed to the shape of the edge between the two sections of the case. The extruded strips maybe cut to length and formed to shape with the abutting ends meeting at a point 16, conveniently at the flat base, with the abutting ends connected by a plate 17, shown also in Fig. 5; The head of tongue strip T is, of course, provided with a tongue 18, and the head of the groove strip G with a groove 19 which, as in Figs. 4 and 5, interfit with the case in closed position. It is to be noted that the tongue 18 and the groove 19 fit together around the entire periphery of the case, so that when the sections are held together in closed position, as by the hinge and draw bolts, or also by the lock, as previously described, the forces which tend to deform the case are resisted by the two strips in unison.
In further accordance with this invention, each of the tongue strip T and groove strip G, as in Figs. 4 and 5, is provided with a central web 20 extending in the opposite direction and on the opposite side of the head from the tongue 18 and groove 19, respectively, while an outer.
flange 21 and an inner flange 22 extend substantially parallel to the web 20 and in spaced relation thereto, with the web 20 preferably having a greater depth, i. e., with the flanges 21 and 22 preferably having less depth than the web 20. The web 20 may also be'provided with an inturned end or bead 23, conveniently'facing to the inside, to add additional strength'to the web 20 and the strips, which can thereby be made slightly lighter in cross section to reduce the weight of the case. 'Each plate 17 may be riveted to the web 20 of the abutting ends of the strips T and G, respectively, as in 'Fig. 5,
by hollow rivets 24. Each plate 17 is preferably placed on the inside, extending beneath flange 22 and is preferably attached to the strips prior to assembly of the case, so that each strip will be a ring-shaped structure for use in assembly. e v
The side walls of the body 3 and lid L, as well as the ends thereof, may be made of a plurality of layers, the
extending edges of which fit between the web 20 and flange 21, while the corresponding edges of the lining and backing for the lining fit between web 20 and flange 22, as in Figs. 4 and 5. The outermost layer maybe a covering layer 25 of a vinyl plastic or other siutable wearresistant material, preferably bonded to an intermediate layer 26 of fibrous material, such as fiberboard, reinforced as by impregnation with plastic on one or both sides,
preferablyat least on the side to which theplastie coveringlayer 25 is bonded, the edges of layers 25 and 26 extending into the space between web 20 and flange 21 of the tongue and groove strips. On the inside, a lining backing layer 27, formed of kraft paper or other suitable material, along with the lining 13 of the lid L and the lining 13' of the body B, respectively; extends into the space between the inner flange 22 and web 20. At
spaced points around the periphery of the tongue strip T of the layers 25.and 26 bonded together and formed into a circular shape of the desired perimeter, with the abutting edges connected by a reinforcing fiber strip 29, on the inside'as shown in Fig. 5, and conveniently attached to the abutting ends by stitching 30 and 30, respectively, shown in Fig. 3. The edges of these endless strips of layers 25 and 26 may then be inserted between the flange 21 and web 20 of the respective tongue strip T and groove strip G and conveniently attached to the webs 20 thereof by the same rivets by which the hardware is attached to the case, such as a rivet 31 for the base 32 of each draw bolt 11 and each rivet headed draw bolt pin 33, preferably bearing against a plastic washer 34 on the outside, as in Fig. 7, as well as the rivets 35 for flanges 36 and 36' of lock 12, as in Fig. 8. Hinge 10, which may be attached by rivets 38, outside the ends of plates 17, as in Figs. 3 and 5, may be attached at this time, but is conveniently attached at a later time, to permit the body B and lid L to be handled separately while attaching the ends thereto, each of which comprises a sheet of layers 25 and 26 bonded together and cut to the desired shape. The layers 25 and 26 of. the sides of body B and lid L may be attached to the end layers 25' and 26', as in Figs. 4 and 5, by the edge strips 40 formed of extruded or molded plastic and fitted around the corner between the sides and ends and secured thereto by stitching 41. The abutting ends of edge strips 40 are preferably placed at the bottom of the case and each joint protected, as by a knee 42 attached by rivets 43 and 43', extending through the layers 25, 26 and 29 at one end, and layers 25' and 26' at the opposite end, as in Fig. 5. In addition, at the bottom, as in Fig. 3, a number of metal buttons 45, each resting on a washer 46 of plastic or other suitable material, may be riveted to the layers 25 and 26, such as a pair of buttons in spaced positions on the bottom of each of the body B and lid L. Buttons 45 support the case when placed in upright position, as in Fig. 1, thereby preventing it from resting on hinge 10 or on the edge strips 40.
The handle H may also be mounted on the body B at this time, as by a flat-headed rivet 50 of Fig. 8 which extends through the base of a U-shaped bracket 51 resting on a washer 52, with rivet 50 extending through the covering layer 25 and reinforcing fiber layer 26 and the inner end of rivet 50 being riveted over against a metal plate 53 which preferably is sufliciently large that the load imposed by the handle H will be distributed over a suflicient area of the side wall of the case that there will be little possibility of the plate 53 damaging the hat box when the box is lifted by the handle H. Of course, with the relatively light-weight construction described herein, the load is quite light, since hats weigh very little and other accessories, such as gloves, stockings and the like which might also be carried in the hat box, do not add unduly to the total weight. The handle H may comprise a generally flattened strip conveniently molded from a suitable material, such as a flexible plastic composition, and provided with molded ends 54 which are arcuate on the outside so as to fit together within a cylindrical cup 55, conveniently closed at its lower end. Both handle H and cup 55 may be pivoted between the legs of bracket'51 by a pin 56, which may be formed in two sections, as in Fig. 9, one adapted to be inserted into the other and the two adapted to be attached together, as by a force fit, or by each being riveted to a side of bracket 51. As will be evident, handle H may pivot about pin 56 so that it may be disposed at any other desired angle to the hat box, thus adding to the convenience of its use. The handle H, at the top of the loop, as shown in Fig. 10, may include a sector-shaped center 57 with a flange 58 terminating in a bead 59 at each side. The width of the handle strip may decrease slightly from about the middle of the loop to each end 54, so that over this portion, the beads 59 first disappear and then the flanges 58 become narrower until only a slight flange 58' exists just above each end 54, as in Fig. 11.
After the handle has been attached to the body section B or prior thereto, the ends of the case sections may be attached to the side walls by placing the edge strips 40 in position and stitching the side walls and ends thereto, after which the knees 42 may be riveted in position. Up to this point, the operations may be conducted on the body B and lid L separately, for convenience in assembly. Then, the hinge may be attached to the two sections of the case and, as a final operation, the linings 13 and 13' may be installed in the case sections. Each lining may be attached to the lining backing 27 in a conventional manner, the edges of the linings 13 and 13' which are to be placed beneath the inner flanges 22 preferably being folded over the edges of backing strips 27, glued in place on the back and then stitched around the edges. The pockets 14 and 14' may be attached to the linings prior to placement in the respective case section, While apron 15 is conveniently attached tothe lining for the lid L prior to placement therein. The edges of the linings are inserted beneath the flanges 22, whereupon the rivets 2% may be installed, and apron 15 then brought down from lid L and attached to lining 13' of .the body B, as by a suitable adhesive. The hat box is then complete.
From the foregoing, it will be evident that the luggage case of this invention fulfills to a marked degree the requirements and objects hereinbefore set forth. The use of interfitting strip means forming the abutting edges of the two sections of a luggage .case, when interfitting together around the entire periphery of the case, provide a relatively strong yet light-weight principal stress resisting member. The central web of these strips, in preferred form, permits the sides of the sections of the case to be attached thereto, as by rivets, quite readily, and also provides a convenient place for attachment of the hardware, including the hinge 1t) and the separable closure means, such as drawbolts 11 and lock 12. The flanges at the inside and outside of these strips protect the edges of the outer layers provided for strength and wear, and also the inner layers of the case. When the inner edge of the web of the tongue and groove strips is provided with a bead, sufficient additional strength is added that the Weight of the strips may be reduced. The tongue and groove strips are particularly adapted to be produced by extrusion of light-weight metal, such as magnesium or magnesium alloys, although other light-weight metal may be utilized. The webs of the tongue and groove strips also provide convenient places for attachment of the hinge or hinges and the luggage hardware, such as drawbolts and a lock or other suitable fastening means, to the principal load sustaining member. The handle for a hat box, constructed in accordance with this invention, is comparatively simple to install and has numerous operational advantages, including the ability to be positioned at any desired angle and to permit the case to be carried conveniently by one hand of the user inserted in the handle loop. The flexibility of the handle loop and the relatively easy positioning thereof at any desired angle tends to minimize the stress on the point at which it is attached to the case.
Although a preferred embodiment of a luggage case, as exemplified by a hat box, has been illustrated and described with particularity, it will be understood that other embodiments may exist and various changes made, all without departing from the spirit and scope of this invention.
