Definitions

  • a speaker box cabinet is formed of laminated sheet [52] 3 217/65 material wherein a thin outer flexible film is supported [51 ⁇ l t Cl ,6 312/330 SM by a thick backing layer and the laminated sheet is [58] d A47! bent at plural locations about thin lines defined by g g fg rxg'z g deep V-grooves which extend through the backing l 1 g 330 layer to the flexible film, and the cabinet is character- I 248 ized by employing additional shallow grooves within the backing layer not reaching the film layer to cor- [56] Reerences Cited rect for camber of the laminated sheet.
  • the depth of the V-shaped grooves is shallower than that required, it is impossible to bend the laminated sheet at the V-grooves or the bent edges are not rectangular but are circular. If the depth of the V-grooves exceeds the correct dimension, the flexible film or outer layer is also cut with the result that the side walls or plates of the cabinet become separated.
  • This invention contemplates the elimination of the aforementioned disadvantages of a conventional speaker box cabinet formed of laminated sheet material and to provide an improved speaker box cabinet insuring that the thin film outer layer remains uncut during the grooving of the inner, relatively thick backing layer to facilitate folding of the sheet into rectangular cabinet form.
  • a speaker box cabinet or the like in which plural longitudinally spaced V-grooves are formed at proper intervals within the thick sheet material backing layer of a laminated sheet having a thin flexible film outer layer and wherein the cabinet is formed by bending the laminated sheet at the V- grooves towards the side carrying the V-grooves and the improvement resides in providing at least one shallow groove within the inner backing layer prior to forming the parallel V-groove along a line which intersects the line of cut of the deep V-groove to correct for camber of the sheet.
  • FIG. 1 is a perspective view of a laminated sheet carrying deep and shallow V-grooves for the construction of a speaker box cabinet or the like by means of the present invention.
  • FIG. 2 is a top, oblique perspective view of the cabinet formed by bending the sheet of FIG. 1 at the deep grooves.
  • a laminated sheet indicated generally at 10 comprises a flexible, thin film layer 1 on the outside of a relatively thick sheet material backing layer 2, the sheet being generally of elongated rectangular form, and when folded inwardly upon itself at longitudinally spaced parallel deep grooves 5 forms a generally rectangular open cabinet 12, FIG. 2.
  • one or more longitudinal grooves 4 of a depth of from one-half to one-third the thickness of the backing layer 2 are formed within the backing layer and preferably along a line parallel to the longitudinal edge 3 of the laminated sheet 10.
  • the V-grooves 5 are formed within the same backing layer 2 at right angles to the thin groove 4.
  • the existence of the shallow groove 4 tends to correct the camber and permit the laminated sheet 10 to lie flat during the subsequent grooving of the laminated sheet 10 at right angles to the longitudinal axis and the shallow groove as at 5 which grooves of course extend completely through the relatively thick sheet material backing layer 2 and accordingly, the accidental cutting of the thin film layer I is almost eliminated by the arrangement of the present invention.
  • the rectangular cabinet is formed by bending the laminated sheet 10 with the V-grooves internal and at the fold lines defined by the deep V-grooves 5.
  • a baffle mounted with a speaker, and a rear cover, are in turn mounted to the front and rear faces thereof respectively to form an enclosed speaker box.
  • a laminated sheet comprising a thin film outer layer bonded to a thick inner backing layer along spaced parallel deep bend grooves extending through the inner backing layer to the outer film layer, the improvement wherein: at least one shallow groove extends longitudinally of said laminated sheet within said inner layer to correct for camber of said sheet prior to forming said deep bend grooves and bending the sheet at said deep grooves, with said deep bend grooves extending uniformly throughout their length, completely through said thick inner layer but not into said thin film outer layer.
  • the longitudinal grooving of the backing layer to remove the camber of the laminated sheet insures that the transverse grooves extend uniformly throughout their length completely through said thick inner layer but not into said thin film outer layer.
