Definitions

  • the valve housing is provided with two non-return valves opening up only in the direction towards the valve housing outlet to the article to be inflated, the first one of said valves being arranged at a point between the valve housing inlet opening towards the larger container and the valve housing opening towards the smaller container and the second valve being positioned at a point between said valve housing opening towards the smaller air container and the outlet towards the article to be inflated.
  • the present invention concerns a device intended to press air into inflatable articles such as air mattresses, rubber boats, inflatable furniture and similar objects, said device comprising one larger and one smaller air container having resilient walls.
  • a device affording a good solution to the problem outlined above consists of a bag trapping a sufficiently large volume of air which volume may be forced into one corner of the bag while compressing the bag.
  • the bag corner forms a separate unit from the rest of the bag through a welded seam incorporating an air inlet opening and air is forced into the article to be inflated from this separate corner.
  • Certain manipulations are required to prevent the air from flowing back into the bag through the opening between the bag and the smaller air container formed by the corner during the compression thereof and this necessity for manipulations sometimes gives rise to difficulties, particularly in case and elevated pressure is required in the inflatable object in question.
  • the purpose of the present invention is to make it possible to inflate articles of the kind referred to in a more efficient and rapid manner.
  • the invention is characterised by a valve housing connected between the larger air container and the smaller air container and having an outlet for the compressed air passing through the valve housing chamber, said valve housing being also provided with a first valve mounted between the larger air container and the valve chamber and with a second valve mounted between the valve chamber and the outlet, said valves both being non-return valves opening only in the direction towards the outlet.
  • FIG. I is a plan view of a bag arrangement in accordance with the invention wherein both air containers are formed by one bag as described above.
  • FIG. 2 illustrates the manner in which the bag arrangement in accordance with the embodiment of the invention illustrated in FIG. 1 is filled with air
  • FIG. 3 is a broken view of a second embodiment of the inventive object, wherein the smaller container is separate'and attached to the rest of the bag arrangement by means of a screw joint,
  • FIG. 4 illustrates a third embodiment of the invention according to which the valve housing is provided on the smaller air container and connectable to the larger air container, parts of which have been broken away in this figure,
  • FIGS. 5, 6, and 7 are longitudinal sections throught the valve housing incorporated in the inventive object, the valves being in positions for filling an article directly from the larger air container, for filling the smaller air container from the larger one, and for filling the article from the smaller air container, respectively,
  • FIG. 8 is a transverse section through the valve housing along line VIII-VIII of FIG. 5,
  • FIG. 9 is a longitudinal section through the valve housing and a part of the two air containers in accordance with still another embodiment
  • FIG. 10 is a side view of the valve housing incorporated in the inventive object in accordance with still another embodiment.
  • FIG. 11 illustrates in a perspective view a nipple incorporated in the valve housing of FIGS. 9 and 10.
  • FIGS. 1 and 2 comprises in accordance with the invention a bag 1 made from e.g. plastic-coated cloth, one corner 2 of which having been separated from the remaining area of the bag by means of a welded seam 3.
  • valve means including a valve housing 5 which communicates through an air inlet opening 6 with the interior of the bag and is provided with an outlet 7 at the outer face of the bag.
  • the valve housing 5 communicates through an opening 8 with the interior of the separate corner 2.
  • a first fllap valve 10 is positioned between the inlet opening 6 and the chamber 9 of the valve housing 5, said flap valve opening up in the direction towards the valve chamber 9.
  • a second flap valve 11 is positioned between the valve chamber 9 and the outlet 7, said valve 11 opening up in the direction towards the outlet.
  • a hose 12 is connectable to the outlet 7 and provided at its outer end with a nozzle 13. The opening 8 debouches directly into the valve chamber
  • the bag is at first filled in the manner illustrated in FIG. 2, i.e. the bag is opened and swung in a sweeping motion with the bag opening facing forwards. Both hands are then used to gather the mouth portion of the bag and wring it to make the bag air tight.
  • the article to be filled is empty from the start it is easy to blow the air straight through the valve housing, past the valves I0, 11 and via outlet 7, hose 12 and nozzle 13 into the article by simply squeezing the bag slightly.
  • the smaller air container formed by the separate bag corner 2.
  • This container naturally has also been filled with air entering from the larger air container during the filling thereof. It is easier to compress the smaller air container than the larger one, and by now squeezing the smaller air container, air is made to enter into the article to be filled, from the smaller container via valve 11, as the first valve acts as an obstacle preventing air from flowing back into the larger container.
  • the second valve 11 locks as a result of the pressure built up inside the article.
  • the smaller container is again filled from the larger one and the procedure described above is repeated a few times until a sufficiently high pressure has been obtained.
  • FIGS. 3 and 4 Two embodiments incorporating this advantageous feature are illustrated in FIGS. 3 and 4, respectively, wherein the valve housing 5 is mounted on a larger air container 14 and on a smaller container 15.
  • the larger air containers are illustrated as partly broken away for more clarity of the figures.
  • the smaller air container 15 is separate and easily replaceable on account of the provision of a connection nipple 16 having internal threads, said nipple being arranged to be screwed onto a pipe socket 17 formed on the valve housing.
  • the pipe socket 17 opens into the valve chamber 9.
  • the smaller container 15 may be attached to the larger air container 14 by means of buttons or in any other way by means of attachment means 18 of known construction.
  • valve housing 5 is attached to the smaller air container 15, and the larger air container 14 may be attached to the housing by means of a nipple l9 fitting a pipe socket 20 on the valve housing 5.
  • a valve housing 5 incorporated in the inventive object comprises two halves 21, 22 assembled for instance by means of glueing.
  • the halves are provided with guide pins 23 and mating holes 24.
  • the second opening 8 debouching into the smaller container. Adjacent the inlet opening 6 is arranged the first flap valve 10 and the second flap valve 11 is arranged adjacent the outlet 7.
  • Each valve consists of a thin, essentially rectangular plate 25 of plastics presenting at two neighbouring corners coaxial pins 26 mounted in corresponding openings in the valve chamber wall such that the plates may be swung towards and away from their valve seats 27.
  • the plates 25 are provided on their top surfaces with a distance shoulder 28 preventing them from abutting flatly against the wall of the valve chamber. In this manner is ensured that the plates adapt themselves readily to the air flows through the valve housing and also that the valves function extremely well.
  • the valve housing may, as indicated by dash anddot lines in FIG. 8, be provided internally with supports 29 for the plates 25, if the latter are thin and slack.
  • FIG. 5 shows the two valves 10, 11 in open position when the pressure in the article to be filled with air is low and the article is filled directly from the larger container 1.
  • FIG. 6 is illustrated the positions of the valves when the pressure inside the article exceeds the pressure of the larger air container, in which case the second flap valve 11 is closed and the first valve 10 open to allow air to be admitted into the smaller air container 2.
  • FIG. 7 finally, illustrates the positions of the valves when air from the smaller air container 2 is forced into the article. The first flap valve is in this instance closed on account of the pressure in the valve chamber 5 exceeding that in the larger air container 1.
  • FIGS. 1 4 The embodiments of the two air containers illustrated in FIGS. 1 4 are imagined made from a plasticcoated cloth surrounding the valve housing which is manufactured from rigid plastics and attached to said housing by means of some adhesive.
