  • the container may be outfitted with components for additional functionality such as wheels 52, handles 50, etc., as shown in figures 8 and 9.
  • the triangulated panels 32 typically two or more per container have two creased minor panels 32 lesser than, equal to or greater than 45 degrees, as shown in figures 2a-
  • the preferred mechanism to allow semi automatic erection of the container is via a tempered curved steel length 30, similar to those typically found in steel retracting rulers, set approximately at 45 degrees to each crease in each panel 32, as shown in figures 3a and 3b. Although a similar result may be obtained from other similar flexing members springs, sprung steel plastic carbon, elastic or other materials, as shown in figures 13 and 14.
  • the curved tempered steel hold several advantages due to its mechanical properties.
  • the steel In its straight state (figure 3a) , the steel has a certain amount of beam strength and remains entirely rigid and true, this is useful to achieve and crispness and rigidity to the container, of significant additional benefit it that there is not manual lock or intervention on behalf of the user to achieve this condition, it is automatic an additional advantage of the steels 'automatic' nature is that it can be hidden inside a container. Additionally, when the steel is folded, as shown in figure 3b, although it retains some tension, it is relatively easy to keep in any convenient position. Lastly, due to it being sprung steel it is in theory eternal and will never fatigue or soften ensuring good quality and product life.
  • panel 32 assembly can be made from sprung steel, and assembled panels 32 of a suitable rigid material, plastic, wood, laminate, etc. with conventional hinged hinges and rivets, modern manufacturing materials and processes allow for the consolidation of three panels 32, two hinges, assorted rivets and a minimum of two locating anchors and accordant ties down to one simple strong component, whose additional features are identified below.
  • the panel 32 is manufactured in one piece with a suitable thermoplastic material including but not limited to polypropylene, copolymer or homopolymer or polyethylene.
  • a suitable thermoplastic material including but not limited to polypropylene, copolymer or homopolymer or polyethylene.
  • An example of the panel 32 is shown in figures 11 and 12.
  • the rectangular panel 32 essentially flat on one side (see figure 12) with the exception of raised rivet bosses and required holes for molding, has on its other side a series of raised ribs 34 constructed in accordance with sound engineering principles to best strengthen the part for the loads it will see and also provide a recess within which the sprung steel length 30 can operate and deflect. Additionally, there are raised ribs 34 neared the perimeter of the part and stepped inboard of the part. This is in order that the panel 32 can sit within a stitched fabric pocket 42. A stitched fabric pocket 42 typically has excess material inside and stepping the perimeter wall in allows a recess within which the excess material can sit. The raised ribs 34 provide a protective tack within which the steel can sit .
  • the single panel 32 is able to hinge along a predetermined axis via the thinning of the material in a particular direction. Additionally, to prevent the panel 32 from hinging in the opposite direction which would be undesirable, ' T 1 shaped posts 38 extrude up from the underside on either side of the hinge and butt against it preventing hinging in the opposite direction.
  • the steel length 30 is inserted from one open end of the panel 32 and is captured via 'pass thru 40' details that are made in the same piece as the main panel 32 and capture the steel.
  • the receiving end of the first pass thru 40 has a flexing member on its end that depresses to allow the steel to enter, once the steel is fully inserted the flexing member returns to its origin and prevents the steel from coming out .
  • the pass thrus 40 at each end are identified due to their curved inner surfaces, that conform to the steel, effectively centering the steel in the track of the panel 32. It is notable that the center pass thru 40 (bridging the live hinge) is of a different profile to the end pass thru 40.
  • the center pass thru 40 inner profile is straight deviating from the curvature of the steel which it bridges, • ll -
  • the flexing panels 32 may be joined in combination in any number of ways to assemble novel containers, for example, panels can be joined to homa frame, i.e. an extruded fluted plastic, or a cardboard box base 12, or a folded extruded pp or pe 'corex' base 12, or a wire base 12, or a wire base 12 covered in fabric or a vacuum formed or otherwise molded base 12 including injection molding.
  • the materials for bases 12 can also be used as a side in any and all combinations.
  • the flexing panel 32 itself to have well defined hinges the panels 32 of the overall five to six sided container, may be joined by hinges, loose fabric hinges; or each panel 32 in any combination may reside inside a fabric pocket 42.
  • the collapsible sidewalls 46, and fixed sidewalls 46 are pivotally attached to the base 12.
  • the base 12 is slipped into a box shaped fabric skin 18 (i.e. the bag 10).
  • Each panel 32 of the skin 18 is doubled up in an outer skin 18 and a liner. This essentially forms pockets 42.
  • the panels 32 simply slip into the pockets 42, therefore the panels 32 in this embodiment are joined via the pockets 42 which form fabric hinges; in a hard case they could be directly affixed to each other.
  • the rivet holes 44 in the panels 32 are anchor points to affix load bearing items, i.e. handle 50 straps and the like.
  • the curved steel length 30 is preferably spring steel, its length 30 is dictated by the panel 32 to which it is affixed, its thickness is 0.005" to 0.010", its width is 0.5"' to 1".

Abstract

La présente invention a trait à un sac comportant une base rigide. Le sac comprend une première paroi rigide repliable en relation de pivotement avec la base. Le sac comprend une deuxième paroi rigide repliable en relation de pivotement avec la base et en relation espacée avec la première paroi rigide d'en face. Le sac comporte une enveloppe disposée autour de la première paroi et la deuxième paroi et reliée à la base. La base, l'enveloppe, les première et deuxième parois formant un espace de rangement lorsqu'elles sont dans un état déployé dans lequel les première et deuxième parois sont maintenues dans une orientation plane sensiblement perpendiculaire à la base, et l'espace de rangement est sensiblement supprimé lorsqu'elles sont dans un état comprimé dans lequel la première paroi et la deuxième paroi sont toutes deux repliées sur la base et sensiblement en parallèle avec celle-ci. L'invention a également trait à un procédé d'utilisation d'un sac.
