Definitions

  • each panel 56 R f d 1 comprising at least one inflatable area and one non- 1 e erences l e inflatable area, the inflatable areas each substantially UNITED STATES PATENTS surrounding the non-inflatable areas, the panels fur- 606,982 7/1898 Smyth 2/177 ther being arranged to mutually support each other.
  • umbrellas and hats which are usually cumbersome and/or inconvenient to transport, since they are separate articles generally too large to carry in a pocket or small handbag.
  • various inflatable hats and umbrellas have been proposed but as far as Applicant is aware, none of these have been successful, since in general they have been uneconomical to manufacture or not sufficiently rigid in use.
  • hats Articles of apparel of the above type will hereinafter be collectively referred to as hats.
  • an article of waterproof apparel comprising an inflatable canopy composed of two sheets of flexible impervious material secured together along lines arranged to define a plurality of interconnected panels in the inflated condition, each panel comprising at least one inflatable area and one non-inflatable area, the inflatable areas each substantially surrounding the non-inflatable areas, the panels further being arranged to mutually sypport each other.
  • the inflatable areas of all panels to be interconnected for the panels to be roughly of sector shape, for the canopy to be basically circular in shape, for the peripheral edge of the interconnected panels to have a zig-zag configuration generally in the plane of the uninflated article and for the edge to be formed as a continuous inflatable area.
  • FIG. 1 is a plan view of an uninflated hat
  • FIG. 2 is an isometric view of the hat in an inflated condition
  • FIGS. 3 and 4 are similar views of an alternative embodiment of the invention.
  • the inflatable hat comprises two superimposed sheets of flexible impervious material welded together along certain lines by high frequency or heat welding depending on the plastics material used.
  • the sheets of material could be, of course, secured to each other along lines using solvent welding or adhesives if these processes are convenient or desired.
  • the lines 1 define eight uninflatable areas 2 'of roughly sector shape arranged so that adjacent areas have common radially extending inflatable areas 3 be tween them.
  • each uninflatable area 2 is defined by a pair of diverging lines originating near the centre of the hat and joined adjacent the periphery by a line 4 of zig-zag configuration.
  • the ends of the lines 1 near the centre of the hat are arranged in a circle so that the radial inflatable areas 3 are all interconnected.
  • the periphery of the hat is formed by a continuous line 5 spaced from and roughly parallel to the lines 4 of each uninflatable area 2.
  • a continuous peripheral inflatable area 6 interconnecting the radial, inflatable areas 3 and having a zig-zag configu ration generally in the plane of the article.
  • the radial, inflatable areas 3 diverge slightly in width from the centre of the hat to its periphery. This is necessary to obtain a bigger ballooning of these areas near the periphery than at the centre when inflated to cause the periphery to contract and the hat to assume a conical shape as shown in FIG. 2.
  • peripheral area 6 provides a fairly rigid periphery to the hat when it is inflated.
  • the hat described above also requires less joining lines than is the case with previously disclosed hats.
  • the hat will, of course, be provided with a suitable valve 7 and may also be provided with chin straps 8 or an attachment for a handle (not shown).
  • the valve 7 may be located in the centre of the hat to communicate with the inflatable areas or at the periphery of the hat as is shown in the drawings.
  • the chin straps 8 are welded to suitable positions on two diametrically opposed non-inflatable areas of two panels. These straps are preferably secured to the sheets of material by a series of transverse welds 9 which extend partway across the straps from each side thereof. Thus, if one such weld tears, the remaining ones will effectively hold the straps onto the hat.
  • the hat In use, the hat may be easily inflated when required and also deflated for transport by means of the valve.
  • the hat in the uninflated condition is of basically hexagonal shape in plan view and is divided into six panels 11 by means of radially extending weld lines 12, which start at a central area of the hat and terminate in a bifurcated weld 13 at the periphery 14 of the hat.
  • the bifurcation thus defined an uninflatable area 15 at the periphery of the hat where each of these weld lines terminates.
  • Each free end 16 of the radially extending welds is enlarged to form an oval or elliptical button on the ends of the welds which are thus arranged in a circle near the centre of the hat. It is considered that this type of button" will be least likely to tear during use, since the six buttons form a disjointed circle with only small spaces 17 there between to enable air to flow to and from the panels from a centrally located valve 18 in the one sheet of material.
  • each panel Centrally located within each panel is an endless weld line 19 which is spaced inwardly from the weld lines 2 defining a panel and the peripheral weld 20 which extends around the entire periphery of the sheets of material.
  • Each endless weld line 19 extends parallel to the peripheral weld line, parallel to the adjacent parts of the bifurcated weld lines 13 and then inwardly to a point 21 in each panel.
  • the inwardly extending parts 22 of each endless weld line converge slightly with the adjacent radial weld lines 12 to ensure the formation of a conical shaped hat in the inflated condition as illustrated in FIG. 4. However, if a substantially flat hat is required, these parts 22 of the endless weld lines may be parallel to the radial weld line.
  • each panel is uninflatable and this part is totally surrounded by an elongated inflatable area.
  • this hat When inflated, therefore, this hat will form a conical shape as illustrated in FIG. 4 wherein the radially extending inflatable areas provide radial rigidity and support, whilst the peripheral inflatable portions provide peripheral rigidity and support.
  • the periphery of the sheets of material must contract and this contraction is taken up by the uninflatable areas at the periphery.
  • the formation of the cone shape is formed by the contraction of the radially extending inflatable portions as a result of the ballooning effect upon inflation. This ballooning effect decreases towards the centre of the hat owing to the fact that the parts 22 of the endless weld adjacent the radial welds converge towards the latter. It is, therefore, important that the peripheral noninflatable areas are in line radially with the radial inflatable parts so that the contraction at the periphery can be taken up easily and effectively by the said noninflatable areas 15.
  • the hat is provided with a pair of chin straps 24 welded to suitable positions 25 on two diametrically opposed non-inflatable areas 23 of two panels.
  • An article of waterproof apparel comprising an inflatable canopy which is flat in its uninflated state composed of two superimposed sheets of flexible impervious material bondedly secured together along lines defining a plurality of interconnected panels, each panel comprising at least one inflatable area and one noninflatable area, the inflatable areas each substantially surrounding the non-inflatable areas and being mutually interconnected, and wherein said inflatable areas include a plurality of radially extending areas joined at the center of said article, bifurcated portions at the outer ends of said radially extending areas and linear peripheral portions extending between said bifurcated portions of adjacent radially extending areas, the panels further being arranged to mutually support each other.
  • An article of waterproof apparel as claimed in claim 1 in which the article is provided with a suitable oral valve communicating with the inflatable areas.
  • said inflatable areas include a plurality of radially extending areas joined at the center of said article and extending outwardly and downwardly therefrom and a continuous peripheral area interconnecting the outer ends of said radially extending areas.
  • said radially extending areas include a central weld line dividing said radially extending areas into two components which branch outwardly at their outer ends to define said bi furcated portions and additionally including an uninflated peripheral area within the confines of said bifurcated portions.
