Definitions

  • the present invention relates to the making of a flexible anatomical padding between the shell of a shoe and the wearer's foot, this padding being made shoe by foot, therefore personalized.
  • This type of padding is sought in particular for shoes with rigid shell, very technical, in particular for the practice of skiing.
  • the present invention therefore aims to overcome the above drawbacks to give reasonable satisfaction to users. It relates to a mixing bottle of reaction products which must ensure homogeneity such that the mechanical qualities, in particular the proven comfort of the padding, is not subject to undesirable local variations.
  • the mixing bottle which can, from the outset, already contain the basic liquid product, is in the general form of a straight circular cyclinder constituted by a lateral surface 1 closed at the lower end by a bottom 11 come in one piece with the surface 1 and also closed at the top by a removable waterproof cover 2, attached, preferably by screwing to ensure this seal better than by elastic interlocking for example.
  • the cover 2 is pierced centrally to allow the passage of the axis 31 of a mixer 3 and laterally, has at least one nozzle 4 for the connection of a tube for the flow of the mixed product to its subsequent polymerization zones .
  • two nozzles 4 advantageously diametrically opposite, will be provided to allow the simultaneous injection, and not in turn, of the same mixture, and under the same momentary conditions of site, pressure, temperature, for the realization of the padding in right and left shoes, which is a significant advantage of the present invention.
  • the axis 31 of the thresher 3 is provided above its sealed crossing of the cover 2 with a head 32 for rotating drive intended to cooperate with a portable power tool, for example of the drill type.
  • this head 32 is in the form of a screw head because the rotary drive tool most frequently used by fitters in the workshops of sports shops is precisely the electric screwdriver.
  • this head 32 could as well have a square shape, or round to be clamped in a mandrel.
  • the axis 31 of the mixer 3 axially crosses the interior of the mixing bottle to the bottom 11 above which it pivots in a holding plate 33 which it retains.
  • This holding plate 33 the configuration of which is related to the inner wall of the bottle 1, with which it has a certain clearance guarantees the maintenance, in operation, of the axis 31 of the mixer 3 in the centered position in the bottle 1. Indeed, in the absence of such a maintenance, the axis 31 in rotation would tend to float or flex and its fins which we will talk about more bin could rub or strike the inner wall of the bottle 1 and spin the beater 3.
  • the axis 31 passes freely through a hole in the holding plate 33 and has, at its end located at a distance from the bottom 11 of the bottle 1, a retaining flange for said plate 33. The latter is thus retained at the axis 31 and, pressing down on the collar of the latter, remains kept away from the bottom of the bottle 1.
  • the axis 31 is also carrying on two diametrically opposite sides of radial fins 34 disposed on several stages.
  • These fins 34 of substantially planar and rectangular shape are inclined relative to the direction of the axis 31 so that, in rotation of the mixer 3, they force the fluid contained in the mixing bottle 1 towards the bottom 11 while l 'inducing in rotation around the axis 31.
  • the fluid in the central part will therefore be driven towards the bottom in an approximately helical movement to then rise along the wall of the mixing bottle 1.
  • the fins 34 on one side appear therefore of inclination reversed with respect to those on the other side but are however exactly in the same position after rotation of a half-turn of the axis 31 due to the symmetry of revolution of order two.
  • this wall is provided with at least two longitudinal deflecting projections 12 extending over all or part of the height of the bottle and leaving sufficient clearance for the passage of the fins 34.
  • These deflecting projections 12 slow down the rotating current of the fluid on the wall of the bottle 1, which ensures better brewing.
  • the deflecting projections 12, in the form of a tooth with a triangular section advantageously have a lower slope on the upstream side, therefore in opposition to the direction of rotation of the fins 34 of the tangential flow of the fluid, than on the downstream side. .
  • FIGS. 2 and 3 shows an illustration of the currents in the mixture in projection from the plane normal to the axis of the mixer 3.
  • These deflecting projections 12 can easily come from a single piece with the surface 1 and the bottom 11 of the bottle in their production by blowing, as is moreover clearly shown in FIGS. 2 and 3.
  • the mixing bottle described above can, as already said, serve as a packaging for the basic liquid constituent of the mixture, the beater 3 being also contained therein or attached thereto before proceeding to the mixing operation.
  • connection pipe is placed on the shoe and preferably communicates with the inside of a textile envelope which is impermeable to the polymerizable and gas permeable product, which will facilitate the elimination of these without the need for additional opening for the evacuation.
  • a connection pipe is placed on the shoe and preferably communicates with the inside of a textile envelope which is impermeable to the polymerizable and gas permeable product, which will facilitate the elimination of these without the need for additional opening for the evacuation.
  • the second product then contained in a separate bottle, is then poured into the mixing bottle 1 already containing the first product and the cover 2 carrying the mixer 3 is closed.
  • the connection pipe or pipes are connected to the nozzles 4
  • the mixing bottle 1 remaining in a substantially vertical position, mixing is carried out by rotating the beater 3, for example by means of a power tool of the drill type, until a perfectly homogeneous mixture is obtained.
  • the time required for mixing obviously depends on the material of the components in order to obtain by expansion a foam of regular quality for good comfort and a correct subsequent holding of the wearer's foot.
  • the control of this mixing time neither too short nor too long, is acquired very quickly since there is no longer any manual intervention for the preparation of the mixture.
  • the mixing bottle 1 is brought to the high position relative to the injection points and is tilted enough to cause the flow of the mixture by gravity and by the natural gas pressure which is created in the mixing bottle 1, in the connection tubes to fill the space to be stuffed.
  • connection tubes After expansion of the foam and polymerization, the connection tubes are torn from the shoe and are discarded with the mixing bottle 1.
  • the mixing bottle 1 is the actual packaging of the basic liquid product, as mentioned at the beginning of the description, it is clear that it is then closed by a preferably traditional cover.
  • the traditional cover of the bottle 1 is then removed and the second liquid product is poured in this bottle 1, the bottle 1 is then closed by screwing it onto the cover 2 carrying the mixer 3, and then the operation is carried out as already said. Because of the speed of the reaction, it is in fact preferable to connect the nozzles 4 before closing the cover 2.
