  • a suitable light weight metal such as an aluminum or magnesium alloy.
  • FIGS. 4 and 5 the central frame of the luggage case has been illustrated in FIGS. 4 and 5 as independent of the shells, for clarity of illustration, since for greater convenience of assembly, the hinges H are not attached to the luggage case until each half or section thereof, including the shells S and S has been assembled.
  • Such assembly may include attaching the frame strip F to opposite ends of the beam B, as by rivets 13 of FIG. 4, then attaching the shell S to the beam and frame strip F; similarly attaching frame strip F to opposite ends of escutcheon E, then attaching the shell S to the escutcheon and frame strip F; and then attaching the hinges H.
  • the frame strip F as in FIGS. 6-8, is formed with a head 14, from which a relatively wide flange 15 extends laterally on the inside, while flange 15 is provided, at a point spaced inwardly from the outer edge, with an inwardly extending rib 16, against which the lining of the case section may abut.
  • the frame strip F is further provided with a thicker lateral flange 17 on the outside, which extends in parallel relation to inner flange 15 to provide a groove into which the peripheral edge of the shell S fits, as shown in dotted lines in FIGS. 6-8.
  • Flange 18 is thinner to accommodate head 19 of frame strip F and is also, so as to overlap the same, conveniently slightly wider than head 19 and outside flange 20 of strip F, the latter of which, in conjunction with a relatively wide, inside flange 21, provides a groove for receiving the peripheral edge of shell S, as also indicated in dotted lines in FIGS. 6-8.
  • Each hinge H as in FIGS. 5-7, comprises two halves formed so that one half 26 overlies flanges 17 and 18 of frame strip F and also a portion of shell S, while the other half 27 overlies a portion of shell S, the two hinge halves being constructed in a conventional manner so as to be pivotal about a hinge pin 28 and shaped to conform to the surfaces which they overlie.
  • Hinge half 26 may be attached to one section of the luggage case by a pair of rivets 29, which extend through the shell S and flange 15, as in FIG. 7, and have a head engaging the inside of flange 15 of frame strip F, as shown.

  • a recess 51 for receiving the respective latches L and L', is formed adjacent each end of the beam and the outer end of each recess preferably slants upwardly, as in FIG. 15, to facilitate access to a lift lever 52 of the respective latch.
  • the bottom of each recess 51 as in FIG.
  • the beam B is provided with a relatively thick, handle supporting section 55 which is provided with a front, lower flange 56 adapted to be received in slot 42 in the face of escutcheon B when the case sections are closed.
  • Each of the end extensions 48 of rear flange 47 of beam B are provided with holes 24 for rivets 13 of FIG. 4, which attach the opposite ends of the beam to the frame strip F, while the end extensions 39 of rear flange 36 of the escutcheon E are provided with similar rivet holes 25, for accommodating the corresponding rivets which attach the opposite ends of the escutcheon E to the frame strip F.
  • the flanges 36 and 4-7 are provided with holes 22, disposed in spaced relation therealong, for the insertion of rivets prior to the attachment of the respective shells S and S, which rivets may later be headed down over the lining of the respective sections of the luggage case.

  • flange 56 along the central portion of beam B, will engage slot 42 of the escutcheon E and each lip 53 of the beam will engage a shoulder 43 of the escutcheon.
  • the frame strip F will overlap the frame strip F, to provide a rigid central framework which is resistant to distortion in any direction, with the case closed, and which is strengthened by the principal load bearing member, i.e., the beam B.
  • Ribs 16 and 16' also contribute to the stability of frame strips F and F, respectively, while the attachment of the shell S to the beam B and frame strip F and the similar attachment of shell S to escutcheon E and frame strip F provides a rigid case construction.
  • Shells S and S may be attached to the framework in any suitable manner, such as including prongs 57 staked into the shell, as in FIGS. 18 and 19, from curved slots 58, in flange 15 of frame strip F and flange 21 of frame strip F.
  • Prongs 57 may be spaced along the ends of the case, such as three or more prongs at each end, depending upon the size of the case. Since the rivets attaching the hinges to the frame strips extend through the shells, staking may be dispensed with along the bottom edges of the shells, but may be utilized, if desired.
  • Each latch L and L may be constructed as in US. Patent No. 3,034,327, as indicated, or may include, as in FIGS. 14 and 15, a longitudinally movable slide 64 having a flange 65 adapted to engage notch 34 of the corresponding hook 33 and connected to lift lever 52 by a generally rectangular link 66, formed of rod or the like.
  • Lift lever 52 is provided with a depending flange which provides a pivot at a post 67, against which a leaf spring 68 abuts and also engages slide 64 to urge the slide toward an open position.
  • Lift lever 52 is also provided with a key operated lock 69, for locking the lift lever in closed position through engagement with a notch in a locking post 70.
  • each lift lever 52 When the case is to be opened, each lift lever 52 is raised, moving slide 64 longitudinally toward the adjacent end of the luggage case, so that each flange 65 will clear the corresponding hook 33. Then, the case may be opened through pivotal movement about hinges H. When the case is closed, each hook 33 will enter the corresponding latch space, whereupon each lift lever 52 may be pushed down, so that each flange 65 will engage a notch 34 in the corresponding hook 33. As in FIG. 15, in closed position, the link 66 slants downwardly toward the adjacent end of the case, thus being overthrown past a neutral position, so that the pressure of spring 68 will maintain the latch closed.
  • each shell is provided with a notch or cutout 79 which corresponds to the space occupied by the beam B and escutcheon E, respectively, the notch of shell S fitting into the groove between flanges 47 and 49 of beam B and beneath end extensions 50, and the notch of shell S fitting into the groove between flanges 36 and 44 of escutcheon E and beneath and extensions 45, with each end of notch 79 abutting rim 40.
  • the edge of shell S does not extend to the inner edge of beam B, while the edge of shell S extends beyond the inner face 41 of escutcheon B, so that the same notch 79 will accommodate either beam B or escutcheon E.
  • each shell is reduced in thickness, as at 80 in FIG. 23, so as to fit into the grooves of the frame, while the top wall 74 of each shell, as in FIG. 21, may be provided with a series of holes 81, spaced along cutout 79, to accommodate attaching pins 59 of FIG. 17, and the bottom wall 75 with holes 82 to accommodate the hinge rivets.
  • the convex walls of the shells provide additional strength against loads or impacts, while the angular rim 76 and corrugation 78 of each shell provides additional strength to resist the load when the case is placed on its side and other luggage cases or objects are piled on top.
  • Each foot 12, as in FIGS. 24 and 25, may comprise a covex bottom flange 83, a sharply inclined flange 84 at each end, a slightly inclined flange 85 at each side and a central post 86, the flanges and post all being integral.
  • a teat 87 extends upwardly, to be received in a hole 88 in the shell S or S, as in FIG. 25.
  • Post 86 is provided with a hole 89, the lower end of which is enlarged to receive the head of a hollow rivet 90, the upper end of which is riveted over onto the inside of the shell, as shown.
  • Each foot 12 may be molded from a suitable plastic, and also may be constructed in the manner of US. Patent 2,950,793.
  • the hat box of FIGS. 26-29 is similar in construction to the luggage case described above, being provided with a beam B, which is a principal load bearing member and to the opposite ends of which a frame strip F is attached, as well as an escutcheon E, which interfits with the beam when the case sections are closed and to the opposite ends of which is attached a frame strip (not shown) but similar to frame strip F and overlapped by the frame strip F, with the case sections closed.
