Definitions

  • the invention relates to a waterproof and unsinkable bag, designed for use in a nautical environment and. in particular, for pleasure boating.
  • Document US-A-3 998 304 discloses a waterproof bag made of flexible and waterproof material, the opening of which is formed by two flexible sheets extending two walls of the bag and intended to be rolled together to close the opening, this closure being maintained by folding down the edges of the side walls of the bag which comprise strips of fastening fabric cooperating with each other.
  • the edges of the side walls of the bag can be folded over one another without the flexible sheets being correctly rolled together, so that the closure of the bag is not then really waterproof.
  • the means provided do not make it possible to avoid breaking the bag under the effect of strong pressure.
  • the object of the invention is in particular to avoid these drawbacks thanks to a new type of tight closure and to a structure preventing the opening of the bag under the effect of high pressure.
  • the two pairs of fabric bands with loops and hooking claws not only guarantee a tight closure of the bag when the side walls are rolled together, but moreover prevent by their presence an incorrect flow of these walls.
  • the bag according to the invention mainly consists of a container (11) and four flaps (12-13-14 and 15).
  • the container and, preferably, the flaps are made of flexible and impermeable material such as, for example, a plasticized or rubberized canvas.
  • the opening (16) of the bag is provided with sealing means (17) which will be described later.
  • the base (18) of the container is substantially rectangular (which could be square) and each flap extends to one side of the base so as to surround a part of the container E, and in particular the sealing means.
  • Attachment means consisting of straps or straps (19) and corresponding loops (20) disposed respectively on two opposite flaps make it possible to keep them in this covering position of the container.
  • the flap (12) is provided four straps (19) arranged side by side along its extreme edge while the flap (13) is provided with four loops (20) fixed by metal eyelets (21). Any similar arrangement can of course replace these straps and these loops.
  • the opposite flaps (14 and 15) are respectively provided with three straps (19) and three loops (20). Reinforcement strips (22) can double the flaps, in particular at the anchor points of the straps and loops.
  • the flaps (14 and 15) being those which are intended to be attached to one another in the first place when the bag is closed, they are provided with straps or side straps (23) and loops (24) corresponding, similar to the straps (19) and loops (20) but arranged along the other sides to trap the two sides of the container which are not covered by the flaps (14 and 15), as illustrated in Figure 6 .
  • the four flaps (12, 13, 14 and 15) are materialized in a single cross-shaped yoke and the central part (25) of this yoke has substantially the same dimensions as the base (18) of the container. (12).
  • the base (18) is fixed to this central part (25) by any suitable means, but preferably by welding and / or sewing its edges along the perimeter of said central part.
  • the container (11) is itself produced from a single piece of flexible and impermeable material, visible in FIG. 8, comprising a median rectangle (or square), constituting the base (18) and two others rectangles (26, 27) located on either side of this median rectangle and intended to materialize the side walls of the container.
  • the way of forming the container (11) appears clearly by comparing Figures 1 and 8.
  • the rectangles (26 and 27) are straightened along the fold lines (30), parallel, delimited both opposite sides of the base (18). Then, the edges (31) of the rectangles (26 and 27) located in the extension of the fold lines (30) are joined to the two other sides (32) of the base (18) while the aligned sides (33 or 34) rectangles (26 and 27) are assembled together to define two vertical joints (35), one of which is visible in FIG. 1.
  • the assembly can be carried out by welds, possibly reinforced by seams.
  • the sealing means (17) essentially consist of two cooperating strips of fabric with claws and hooking loops (37 and 38), fixed externally along two substantially parallel side faces of the container defined respectively by the rectangles (26 and 27), said strips extending between the two aforementioned joints (35). They are arranged parallel to the two free edges (39, 40) delimiting the opening (16) of the container (11).
  • the strips (36 and 37) are unequally spaced from the corresponding edges (39 and 40) so as to be able to hang against each other after said two lateral sides of the container have been wound together over a certain length at from the opening (16); in addition, the sealing means (17) comprise two cooperating bands (41 and 42) fixed externally to said lateral faces and facing each other, in the vicinity of the edges (39 and 40), respectively. These two strips (41 and 42) could be replaced by a waterproof type zipper. Finally, it should be noted that the border (39) is provided with a flexible lip (39a) which can be folded down on the bands (41 and 42), when the latter are joined together.
  • the strips of fabric with claws and loops (41 and 42) are first united (fig. 2) so as to trap said objects together with a certain volume. of air.
  • the effective volume occupied by the objects introduced into the container (11) the latter will always keep substantially the same volume after closing, due to the air trapped at the time of the joining of the bands (41 and 42 ).
  • the lip (39a) is then folded over the two edges (39 and 40) joined by the strips of claw fabric (41 and 42). This is the situation illustrated in FIG. 3.
  • the upper part of the container is rolled up on itself until the external cooperating strips (36 and 37) meet, as illustrated in FIG. 4.
  • the two end portions of the upper part of the container thus wound on themselves are then folded down towards the center as illustrated in FIG. 5.
  • the two flaps (14 and 15) are then attached to one another (fig. 6 ) by means of the straps (19) and corresponding loops (20).
  • the side straps (23) are attached to their respective loops (24). It only remains to join the flaps (12 and 13) by means of the four straps (19) and loops (20) which they carry, so that the closed bag takes the configuration illustrated in FIG. 7.
  • a handle ( 45) can be provided on the flap (12).
  • One can also provide shoulder straps fixed under the central part of the cross-shaped yoke defining the flaps to be able to use the bag of the invention in the manner of a backpack.
