Description

15613

  The invention relates to a waterproof and unsinkable bag,

  designed for use in nautical environments and, in particular,

  for pleasure boating.

  Most so-called sealed bags do not offer protection

  effective compared to the rain.

  in the water almost always gives rise to infiltrations

  On the other hand, the closure means of the bag poorly resist forced immersion thereof and, most often, the bag undergoes a sort of disembowel under the effect of the pressure of the water exerted from all sides

on its walls.

  The invention proposes to solve these disadvantages by firstly, to a structure protecting the closure means, so as to avoid disemboweling,

  and thanks to a new type of waterproof closure.

  For this purpose, the invention relates primarily to a

  waterproof bag characterized in that it consists essentially-

  at least one container of flexible and waterproof material

  méable, sealing means of said container and at least one holding flap extending the base of said container and capable of surrounding a portion of the latter and, in particular, said sealing means; fastening means being provided for holding said flap

in this position.

  Preferably, the base of the container is substantially

  rectangular or square and four flaps are pro-

  along each side of said base.

  According to another feature of the invention, the closure means comprise two cooperating bands of claw fabric and attachment loops fixed externally along two substantially parallel lateral faces of said container, respectively, parallel to two boundaries delimiting

  the opening of the latter These two cooperating bands are unequally spaced corresponding edges so that they can come to hook one against the other after said two side faces have been wound together over a certain length from

of said opening.

  The invention will be better understood and other advantages

  will appear better in the light of the description of the

  following statement of a current embodiment

  of a waterproof bag in accordance with the principles of the invention.

  FIG. 1 is a perspective view of the bag, prior to closure; Figures 2 to 5 are partial views of the same bag, illustrating its closure; Figure 6 is a perspective view similar to Figure 1 showing the last closing phase of the bag; the closure 7 is a perspective view of the same bag, closed; and Figure 8 illustrates the constitution of the container

said bag.

  Referring to the drawings, the bag according to the invention consists mainly of a container (11) and four flaps (12-13-14 and 15) The container and, preferably, the flaps are made of flexible material and waterproof as,

  for example, a laminated or rubberized canvas.

  The bag (16) is provided with sealing means (17) which will be described later. The base (18) of the bag is substantially rectangular (it may be square) and each flap extends one of the sides of the bag. the base so as to surround a part of the container and, in particular, the

  sealing means -Means of fastening

  spaced loops or straps (19) and loops (20) respectively arranged on two opposite flaps allow to maintain them in -the position of recovery of the container Thus, if we consider the flaps (12 and 13) opposite and located from and other of the container

  (11) so as to be attached to each other by imprisonment

  The flap (12) is provided with 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). Analogous can of course replace these strips and buckles Similarly, the opposite flaps (14 and 15) are respectively provided with three strips (19) and three loops (20) Reinforcement strips

  (22) can double the flaps, especially at anchor points.

  On the other hand, the flaps (14 and 15) being those which are intended to be attached to each other in the first place at the closure of the bag, they are provided with

  straps or side straps (23) and loops (24) cor-

  corresponding, similar to the strips (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 shown in Figure 6.

  To simplify manufacture, the four flaps (12, 13, 14 and 15) are embodied in a single cross-shaped yoke and the central portion (25) of this yoke has

  substantially the same dimensions as the base (18) of the container.

  neur (12) Thus, the base (18) is attached to this central part

  trale (25) by any suitable means, but preferably by welding and / or stitching of its edges along the perimeter of said central portion Furthermore, the container (11) is itself made from a single piece of flexible and waterproof material, visible in Figure 8, having a median rectangle (or square), constituting the base (18) and two other rectangles (26, 27) located on either side of this median rectangle and intended to materialize the side walls of the container The manner 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, delimiting two sides opposite the base (18) Then, the edges (31) of the rectangles (26 and 27) in situated in the extension of the fold lines (30) are assembled to the two other sides (32) of the base (18) while the aligned sides (33 or 34) of the rectangles (26 and 27 )

  are assembled together to define two vertical joins

  shims (35), one of which is visible in Figure 1.

  may be welded, possibly reinforced by

seams.

  The sealing means (17) consist essentially of

  essentially two cohesive strips of claw fabric and hooking loops (37 and 38) fixed externally along two substantially parallel lateral faces of the container respectively defined by the rectangles (26 and 27), said strips extending between the two joints (35) mentioned above They are arranged parallel to the two free edges (39,40) delimiting the opening (16) of the story (11) The strips (36 and 37)

  are spaced unequally from the corresponding borders (39 and 40)

  in such a way that they can catch one against the other after the two side laces of the container have been wound together over a certain length from the opening (16); in addition, the sealing means (17) comprise two cooperating strips (41 and 42) fixed externally to said lateral faces and in

  vis-à-vis, in the vicinity of the borders (39 and 40), respec-

  These two bands (41 and 42) could be replaced by

  Finally, it should be noted that the border (39) is provided with a flexible lip (39 a) foldable on the strips (41 and 42), when

these are united.

  The method of closure of the bag will now be described, with reference to FIGS. 2 to 7. Since the protective articles are introduced into the container (11), the strips of claw and loop fabric (41 and 42) are first joined together ( 2) so as to trap said object at the same time as a certain volume of air. Thus, whatever the actual volume occupied by the objects introduced into the container (11), it will always remain substantially the same volume. after closing, due to the air trapped at the time of the meeting of the strips (41 and 42) The lip (39 a) is then folded over the two borders (39 and 40) together

  by bands of claw tissue (41 and 42) This is the situation

  3, the upper part of the container is wound on itself until the external co-operating strips (36 and 37) meet, as illustrated in FIG. 4. The two end portions of the container upper part of the container and wound on itself are then folded towards the center as shown in Figure 5 The two flaps (14 and 15) are then attached to one another (Figure 6) by means of the strips (19). In addition, the side straps (23) are attached to their respective loops (24). It remains only to join the flaps (12 and 13) by means of the four straps (19) and buckles ( 20) that they wear, so that the

  bag closed takes the configuration shown in Figure 7.

  A handle (45) may be provided on the flap (12).

  also provide shoulder straps fixed under the central part

  trale of the cross-shaped yoke defining the flaps to be able to use the bag of the invention in the manner of a backpack It is noted that with such a structure, the disembowel of the bag under the action of any external pressure, is avoided by the presence of the four flaps, the sealing means (17) can no longer take place. In addition, if external pressure is exerted on the walls of the container, the little air flowing through the strips (41 and 42) helps to press the lip (39 a) more strongly against the wrapped walls of the container

  and therefore, to strengthen the seal.

  Of course, the invention is not limited to the only embodiment of the bag which has just been described. In particular, it is very easy to imagine to subdivide the container (11) into

  several containers placed side by side in the center of an

  cross-shaped base defining the four flaps described above It is to say that the invention covers all the technical equivalents of the means involved if they

  are within the scope of the following claims.
