Ground Mat Patents (Class 5/417)
  • Patent number: 4516668
    Abstract: A combination knock-down handbag and mat which is formed of a blank of sheet material of a predetermined length and width which is peculiarly seamed and secured so that in the assembled or folded position, the blank forms a handbag and in the unfolded position the blank defines a mat, e.g. a beach mat. To form the mat, which can be subsequently formed into a handbag, one end of the blank is initially reversely folded onto a portion of the blank and secured thereto to define one or more open end pockets. A handle is secured to the open end of the pocket. To convert the mat into a handbag the remainder or extended portion of the blank is reversely folded in accordian fashion to the size and shape of the reversely folded portion. The opposed end portions of the folded blank thus folded are then folded relative to the central portion thereof. With the blank so folded, the central pocket thus formed is turned inside out to define the handbag in the final folded position of the blank.

  • Patent number: 4489815
    Abstract: This invention relates to dual purpose tote bags in which one purpose is to provide a carrying bag or box and the other is to provide for a semi-rigid surface, which can be used for carrying and, holding food and for providing a table-like surface during picnics and outings. Prior devices have never fully satisfied the second purpose, their surfaces being too soft and pliable, this leading to problems in fulfilling the first purpose also in that the bag would not provide a semi-rigid internal space for carrying a payload. This invention teaches a new construction and a new method for converting from one purpose to the other.The new construction is both internal; employing three layers, the center layer being of semi-rigid material and, external; in the arrangement of the panels of the three-layered material.The new method of folding employs a stepwise folding of the flat panels into a box-like shape, suitable for maintaining a semi-rigid internal space.
