Definitions

  • ABSTRACT A suitcase essentially consisting of frames of extruded light metal and planar panels of rigid wood is assembled by edges of the panel members being adhesively fastened in elongated grooves of the frames, one side wall of each groove being provided with integral, 10ngitudinal ribs. The ribs mechanically interlock with the adhesive layer and prevent the adhesive from being released from the frame under unfavorable conditions.
  • This invention relates to suitcases and like pieces of luggage, and particularly to improvements in a piece of luggage essentially consisting of grooved frames and panels whose edge portions are received in the grooves of the frames.
  • the primary object of this invention is an improved bond between the adhesive layer and the metal of the frames which does not rely on adhesive material of any specific composition, but is effective regardless of the type of adhesive employed.
  • the invention in its more specific aspects, resides in a piece of luggage which has a body portion,'a cover portion, and a sealing arrangement which releasably seals the cover portion to the body portion, and particularly seals the cover portion to one of the two frames of the body portion, hereinafter referred to as the body rim frame, the other frame being the bottom frame.
  • the bottom panel has an edge portion received in a groove in the inner circumference of the bottom frame.
  • the body rim frame is offset from the bottom frame transversely of the bottom panel, and both frames are formed with respective second grooves open toward each other, in which respective edge portions of a body side panel are received.
  • the cover portion includes a top frame and a top panel whose edge portion is received in a third groove which extends in the inner circumference of the top frame.
  • the first-mentioned groove and the second and third grooves respectively define first, second, and third planes.
  • the first and third planes are parallel to each other and perpendicular to the second plane in the closed condition of the piece of luggage.
  • Each of the grooves is bounded transversely of the associated plane by two opposite faces of the corresponding frame, and at least one of the two opposite faces is formed with respective pluralities of alternating projections and recesses.
  • the adhesive When a layer of adhesive is interposed between the irregularly shaped face of the frame and the edge portion of a panel received in the groove, the adhesive is mechanically interlocked with the face and also prevented from flowing out of the groove when softened by heat, particularly when the projections are ribs parallel to the open side of the groove.
  • FIG. 1 shows a suitcase of the invention in fragmentary elevational section
  • FIG. 2 shows a modification of the suitcase of FIG. 1 in a corresponding view.
  • FIG. 1 in more detail, there is shown only as much of a suitcase as is needed for an understanding of the invention.

  • the top edge of the side panel 17. is received in a groove 21 of the body rim frame 2, the grooves 13 and 21 being open toward each other and jointly defining the lateral plane of the suitcase body in which the side panel 17 is located.
  • the frame 2 is approximately U-shaped in cross section, and the vertical walls of the groove 21 defined by the legs of the U-shape are of equal width.
  • the surface 23 of the inner wall carries ribs 14.
  • a heavy sealing rib 24 projects upward from the bight portion of the U- shape and terminates in a flat horizontal sealing face 25.
  • Adhesive not explicitly shown, fastens the frame 2 to the side panel 17.
  • the cover portion of the suitcase includes a top frame 3 having a horizontally open groove 31 in its inner circumference.
  • the wooden top panel 32 of the cover portion is partly received in the groove 31 and adhesively fastened to the frame 3, as described with reference to the bottom panel 16 and the bottom frame 1.
  • the frame 3, as far as described so far, is .I-shaped in cross section, the longer leg 38 of the J-shape providing the inner wall 33 of the groove 31 and being provided with longitudinal ribs 14 for better anchorage of an adhesive film, not itself explicitly shown.
  • the hollow side panel of the suitcase cover is an integral part of the frame 3 and depends from the bight portion of the .I-shape.
  • the outer and inner aluminum layers 34, 35 of the side wall are connected by spaced transverse stiffening members 36, 37, and the latter, jointly with the free edge portions of the layers 34, 35, bounds a downwardly open groove 38 in which a cylinvdrical sealing string 50 of resilient material, such as rubber, is retained by ribs 39 projecting into the groove 38 from the aluminum layers 34, 35.
  • the aforedescribed sealing rib 24 is so dimensioned that it can enter the groove 38 in the illustrated closed position of the suitcase for sealing engagement between the face 25 and the rubber string 50.
  • All wooden panels 16, 17, and 32 are provided with protective and decorative outer skins 70 of adhesively fastened, softer polyvinyl chloride composition, and all exposed aluminum surfaces of the frames 1, 2, 3 are provided with coarse corrugations or ribs 60 elongated parallel to the bottom and top panels 16, 32, except for planar outer surface portions 134, 135 on the aluminum layer 34 which are dimensioned for receiving identifying labels and bounded by the corrugations or ribs 60 which protect the labels.
  • the ribs 60 contribute to the stiffness of the frames, have a decorative effect of their own, and reduce the detrimental effect of scratches in the relatively soft aluminum surfaces on the appearance of the suitcase. Such scratches cannot be avoided entirely by the artificial oxide layer with which all exposed aluminum surfaces are provided by anodizing in a conventional manner prior to assembly with other elements of the suitcase.
  • the suitcase partly shown in FIG. 2 differs from that described above with reference to FIG. 1 by the construction of its cover portion which is assembled from a top frame 3' surrounding the top wall 32, a cover rim frame 4, and a cover side panel 48.
