Definitions

  • the present invention relates to improvements in carry bags and, in particular, to a carry bag that stabilizes its contents by the application of a vacuum.
  • the invention relates to a backpack which includes an inner airtight bag which may be evacuated of air by a suction device for compressing the bag tightly and sealably against the contents of the bag.
  • carrier bag as used in this specification embraces such items as backpacks, rucksacks, satchels, knapsacks, handbags, suitcases, riding or saddle bags, duffel bags, motorcycle panniers, and webbed carry pouches, such as those used by the military. All of these carry bags are designed to reliably envelope, and provide some degree of restricted access to, their contents, as well as provide a means of conveyance to the user, such as by handles, straps, buckles or latches.
  • the pack has a waist belt at its lower edge, and opposite side edges of the pack are tethered to the sides of the belt by the compression-suspension system which attaches to the pack by a strap at multiple spaced-apart locations.
  • the system includes several straps which are subject to tensioning force and thus adjustable to laterally compress and stabilize the pack and its contents in a comfortable position.
  • Prior art patent document US 6,047,413 discloses a protective garment having a backpack portion adapted to conform to equipment worn on a back of a wearer of the protective garment.
  • the backpack portion includes an outer protective layer that is gathered, and a plurality of elastic members are connected to an interior surface of the outer protective layer so that it is drawn toward and conforms to the worn equipment.
  • a carry bag comprising flexible walls defining an enclosure adapted to house contents of the bag, the enclosure having an opening for receiving the contents therethrough, the opening being sealable for airtightness of the enclosure, and means for evacuating air from the enclosure so as to compress the walls against the contents to thereby restrain the contents from movement.
  • the enclosure is an inner bag of the carry bag.
  • the air evacuating means is a suction pump.
  • the walls of the inner bag and its contents are compressed against a rigid support wall of the carry bag.
  • the carry bag is a backpack having a rigid support wall adapted to abut against the back of a user, and including an inner bag having flexible walls and a sealable opening that allows contents to be packed and sealed within the inner bag and for a vacuum to be created and maintained when the opening is sealed.
  • the inner bag is coupled to an air pump that, in use, evacuates air from the inner bag so as to cause the contents to be tightly secured against the rigid support wall, thereby reducing the volume of space occupied by the carry bag.
  • Figure 1 is a partly disassembled, perspective view of a carry bag according to a first preferred embodiment of the invention
  • Figure 2 is a schematic, side view showing two stages in the evacuation of air from an enclosure forming part of the carry bag of Figure 1,
  • Figure 3 is a perspective view of a carry bag according to a second preferred embodiment of the invention showing a first stage of use
  • Figure 4 is a similar view to that of Figure 3 but showing a second stage of use

  • FIG 6 is an enlarged and isolated view of a valve arrangement for suction means used in the carry bag as shown in Figure 5,
  • Figure 7 is a perspective view of a carry bag according to a third preferred embodiment of the invention
  • Figure 8 is a rear view of the carry bag of Figure 7
  • Figure 9 is a side view of the carry bag of Figure 7 showing contents and an airtight inner bag enclosing same which has not been evacuated of air,
  • Figure 10 is a view similar to that of Figure 9 but in which air has been evacuated from the airtight inner bag to compress the contents against a rigid support wall of the carry bag,
  • Figure 11 is a perspective view of a carry bag according to a fourth preferred embodiment of the invention supported on a motorcycle,
  • Figure 12 is a side view of the carry bag shown in Figure 11 showing contents and an airtight inner bag enclosing same which has not been evacuated of air,
  • Figure 13 is a view similar to that of Figure 12 but in which air has been evacuated from the airtight inner bag to compress the contents against a rigid support wall of the carry bag,
  • Figure 14 is a perspective view of a carry bag according to a fifth preferred embodiment of the invention showing a first stage of use
  • Figure 15 is a view similar to that of Figure 14 but showing a second stage of use
  • Figure 16 is a view similar to that of Figure 15 but showing a third stage of use
  • Figure 17 is a view similar to that of Figure 16 but showing a fourth stage of use
  • Figure 18 is a view similar to that of Figure 17 but showing a fifth stage of use
  • Figure 19 is a side view of a carry bag according to a sixth preferred embodiment of the invention showing a first stage of use
  • Figure 20 is a view similar to that of Figure 19 but showing a second stage of use
  • Figure 21 is a rear view of a carry bag according to a seventh preferred embodiment of the invention showing a first stage of use
  • Figure 22 is a view similar to that of Figure 21 but showing internal detail
  • Figure 23 is a perspective view of the carry bag of Figure 21,
  • Figure 24 is a side sectional view of a pump assembly that may be used in or with the carry bag of the invention, the pump assembly being shown in an open configuration, and
  • Figure 25 is a similar view to that of Figure 24, but showing the pump assembly in a closed configuration.
  • the carry bag 10 shown in Figure 1 includes a base plate 12, an airtight bag 14 with a ziplock opening 16 and a suction pump coupling 18 attached to the airtight bag 14, and a protective outer sleeve 20 with a suction pump 22 attached thereto. Air can be evacuated from the bag 14 to compress any contents 24 therein against the base plate 12 in the manner as shown schematically in Figure 2 by connecting the suction pump 22 to the coupling 18 and operating same.
  • the carry bag 30 shown in Figures 3 to 5 is used, in a first stage, to receive contents through an outer sealable opening 32.
  • the opening 32 is then closed to provide an airtight enclosure around the contents, and a hand pump 34 is then operated to evacuate air from the airtight enclosure.
  • Flexible walls of the enclosure compress against the contents and hold them tightly in place.
  • the one way valve 36 shown in Figure 6 ensures that air cannot return into the enclosure during and after the operation of the hand pump 34.
  • the carry bag 40 shown in Figures 7 to 10 is similar in structure and function to the carry bags described above, but is adapted specifically for use as a backpack. Like features between the carry bags have been assigned like numerals in the drawings.
  • Figure 10 in particular, identifies the inner bag 14 evacuated of air and its walls and the contents enclosed therewithin compressed against the rigid support wall 42.
  • the carry bag 50 shown in Figures 11 to 13 is adapted specifically for use as a pannier for a motorcycle. Again, like features have been assigned like numerals in the drawings.
  • the carry bag 60 shown in Figures 14 to 18 is used, in a first stage, to receive contents 62 through an outer sealable opening 64. The opening 64 is then closed to provide an airtight enclosure 66 around the contents, and a hand pump 68 is then operated to evacuate air from the airtight enclosure. Flexible walls 69 of the enclosure compress against the contents and hold them tightly in place. The volume of space occupied by the carry bag 60 has thus been significantly reduced and the contents are prevented from movement relative to the bag.
  • the carry bag 70 shown in Figures 19 and 20 is similar in structure and function to the carry bags described above, but is adapted specifically for use as a backpack.
  • Figure 20 in particular, identifies an airtight bag 72 evacuated of air and its walls and the contents enclosed therewithin compressed against a rigid support wall 71.
  • the backpack 70 includes a stiffened base plate which serves as the support wall 71, an airtight bag 72 having a flexible wall with a ziplock opening 74 that provides an airtight resealable closure, a one-way air valve 76 mounted to the flexible wall, and a flexible air hose 78 connected at one end to the valve 76 and at the other end to a vacuum pump 80.
  • Air can be evacuated from the bag 72 to compress contents 82 of the bag against the rigid support wall 71 in the manner as shown schematically in Figure 20 by manually operating the vacuum pump 80 (according to a reciprocating or pumping motion of the pump).
  • the outward flow of air from the bag 72 and through the air hose 78 is shown by arrows A, and the inward movement or compression of the flexible wall of the bag against the contents 82 is shown by arrows B.
  • the backpack 70 can thus be worn with the aid of shoulder straps 84 by a user and, as the flexible wall of the airtight bag 72 firmly follows the outermost shape or profile of the contents 82, the contents will not move relative to the backpack during even violent movement of the user wearing same and the total volume of space occupied by the backpack 70 is significantly reduced.
  • the carry bag 90 shown in Figures 21 to 23 is similar in structure and function to the carry bags described above, but is adapted specifically for use as a medium sized backpack, also known as a daypack. It has a very light weight structure consisting of an airflow or breathable vest 92, a cavity 94 for a hydration container, say, for a sports beverage, and dual waterproof independent chambers (only a single chamber 96 shown) which are capable of being evacuated of air therewithin by a pump device 98.
  • the daypack also has foam ribs 97 for back aeration and a waste strap 99 with a foam support.
  • the pump assembly 101 shown in Figures 24 and 25 may be used in or with any one of the carry bags described above.
  • the pump assembly 101 utilizes two simple one way valves.
  • An inner, smaller valve 102 maintains an airtight seal of the bag when the pump assembly is not in use.
  • the pump assembly has been designed to close off the inner valve 102 by means of an extension 103 to a top moulding of a valve cap 104, which clamps down on the inner valve 102 when the pump assembly is shut after use.
  • the valves are of a conventional kind found on rubber inflatables and on simple foot pumps used for camping, and have thin rubber sheets that act as a type of diaphragm seal.
  • valves ensures that they remain in a closed state unless forced open by pressure from beneath or within the carry bag
