Definitions

  • the present invention concerns the opening of the protective cover for an inflatable body, for instance, a life jacket, and it is an object of this invention to provide a device which will be able automatically, reliably and repeatedly to carry out the opening of a protective cover in response to the exertion of an inflating pressure.
  • An automatic opening is of particular importance in connection with life jackets and the like because in many instances the respective user of such device is not able to open the protective cover himself.
  • an object of the present invention to provide a device of the above mentioned general type which will meet the above outlined requirements and will automatically transform an inflatable body, for instance a life jacket, from its wrapped or packed condition into its condition ready for use.
  • FIG. 1 illustrates a device according to the present invention, partially in section.
  • FIGS. 2 and 3 illustrate on a larger scale than FIG. 1 a detail of the present invention.
  • FIGS. 4, and 6 show the device according to the invention in different positions.
  • the present invention makes use of a zipper system known per se according to which, when the marginal interengageable portions of the two zipper strips are in closed condition, by a sharp bending a small opening is produced from where both strips will disengage each other when subjected to pull or pressure so that the zipper will open its entire length.
  • This zipper furthermore has the property that it can be returned to its closing condition by means of a customary di splaceable slide.
  • such zipper is provided for the protective cover of an inflatable body and at the opening area is with both strips closed and bent clamped in a clamping member which narrows in such a way that the strips will disengage each other when they are pulled out of the clamping member connected to the protective cover.
  • a clamping member which narrows in such a way that the strips will disengage each other when they are pulled out of the clamping member connected to the protective cover.
  • FIG. 1 shows an inflatable body 1 of a life jacket in packed together condition in which the wall portions of the inflatable body are folded together and located within a protective cover 2.
  • a compressed air bottle 4 with opening device 5 and handwheel 6 is mounted on and connected to the supporting frame 3 for the device.
  • a conduit 7 leads to the body 1 for filling the same.
  • the protective cover 2 when in its packed condition, is held closed by a zipper As shown on a larger scale in FIG. 2, the zipper 8 is with the adjacent portions of the protective cover 2 in closed condition with a loop 9 introduced into a clamping member 10 arranged within the protective cover 2.
  • the clamping member 10 has for the loop 9 a hollow chamber 11 with an exit opening which latter is adapted by means of a roller 12 and a pivotable lever 13 to be varied as to its width, said lever being adapted to be pivoted into the dot-dash line position for introducing the loop 9.
  • the clamping member 10 is connected to the protective cover 2 of the floating body I by means of a strap 14.
  • the pulling out of the zipper 8 from the clamping member 10 may be aided by giving the strap 14 only a limited length and connecting the same to a fixed marginal area within the protective cover. It will be appreciated that in such an instance the gas pressure forming in the floating body 1 will after tightening the strap 14 act upon those portions of the walls of cover 2 which are adjacent to the loop 9 of the zipper 8 and will pull the loop 9 out of the opening of clamping member 10 as indicated by arrows in FIGS. 3 and 4.
  • the zipper 8 may be provided with an inwardly pointing curvature 17 (see FIG.'6) so that at this area the inflating pressure will become first effective. In this way there is the additional assurance that the zipper 8 will easily open.
  • the emptied floating body 1 and its protective cover 2 may, by closing the zipper 8 by means of the slide 15, be returned to their previous inactive condition.
  • the protective cover 2 is provided with an opening which is adapted to be closed by a separate zipper 16 of standard type and through which opening the clamping member 10, the interior of cover 2 and the slide of zipper 8 are accessible from the outside.
  • a protective cover adapted normally to fully receive and store said inflatable body, said protective cover having a release opening for releasing therethrough the major portion of said inflatable body, conduit means leading into said inflatable body for conveying pressure fluid into said inflatable body to inflate the same and to expel the major por tion of said inflatable body through said release opening, slide fastener means including two strips with interengageable elements adapted to engage and disengage each other for respectively closing and opening said release opening, and clamping means associated with said protective cover and defining relatively wide chamber means and relatively narrow passage means leading from said chamber means toward the outside, said chamber means being adapted to receive and store a relatively wide loop of said slide fastener means extending through said relatively narrow passage means, said slide fastener means being adapted in response to the inflation of said inflatable body to have said relatively wide loop section pulled out said chamber means through said narrow passage means whereby simultaneously said slide fastener means near said narrow passage means breaks open and continues to break open to release the major portion of said inflatable body.
  • clamping means is formed by a U-shaped yoke partly defining said relatively large chamber means, means supported by said yoke defining said relatively narrow passage means.
