Definitions

  • the invention relates to a ski boot, comprising an outer boot, an inner boot and an air cushion between the inner boot and the outer boot with at least two separate air chambers and filling and emptying means for the air chambers.
  • Such a ski boot is known from DE-OS 33 10 812.
  • a special pump chamber is provided for each air chamber.
  • the invention has for its object to provide a generic type of ski boot that different T.ufthuntn can be operated with less pump effort.
  • the air chambers are assigned a common pump chamber, which is connected to the two air chambers via a valve unit with a manually operable main valve.
  • a particularly expedient circuit which makes it possible to operate two or more air chambers from a common pump chamber, consists in that the pump chamber is connected to the atmosphere via a first check valve opening towards the pump chamber and to the individual air chambers via a series connection of one closing to the pump chamber, the second check valve close to the pump chamber and a main valve close to the respective air chamber is connected, between the respective second check valve and the respective main valve in each case a biased in the closed position and openable by hand.
  • the main valve close to this air chamber is opened to inflate one air chamber, while the main valve associated with the other air chamber or the other air chambers remains closed. In this way, one air chamber can be selectively inflated to the desired degree of filling.
  • the main valve which can be designed, for example, as a screw valve, can easily be produced with the necessary sealing action, so that pressure retention in the air chambers is ensured.
  • the two air chambers can be formed by a common edge-welded pair of foils with a separating weld seam, for example in such a way that the pump chamber with one valve unit for each of the two air chambers is arranged on one of the foils in the region of the separating weld seam. This ensures the shortest possible routes.
  • the two valve units can be combined by the material of a rubber body defining the pump chamber to form an assembly with the pump chamber. In this way it is ensured that no exposed cable routes are exposed to a risk of damage.
  • the air chambers are formed by a pair of foils with a separating weld seam
  • the one foil of this pair of foils lying against the rubber body can form an end wall of the pump chamber, which results in a simple construction and a simple method of manufacture for the pump.
  • openings can then also be provided which are in register with connection bores of the valve units, which in turn ensures the simplest routing of the lines.
  • the air cushioning can extend over the forefoot area and the ankle side areas; in this case the pump chamber and the valve units can be arranged above the instep area. It has been shown that in such an embodiment, a favorable stabilizing and cushioning effect for the foot can be achieved if the dividing line between the two air chambers runs along the longitudinal median plane of the foot. An optimal lateral adjustment of the foot within the shoe can then be ensured by differently inflating the two air chambers on both sides of the longitudinal center plane of the foot.
  • the dividing line can be formed in this area by an air-free band of about 1 to 4, preferably 2 to 3 cm wide, for example by two parallel weld seams or by a correspondingly wide one Surface welding.
  • the air chambers can be designed in a ring shape to match the anatomical conditions.
  • the ring-shaped air chambers are delimited in their respective central area by an annular weld seam between the films of a pair of films, the film material being retained within this ring weld seam.
  • an inner shoe is denoted by 1.
  • An air cushion generally designated 2 is applied to this inner shoe 1.
  • this air cushioning consists of a pair of foils 18 with two foils 18a and 18b.
  • the padding covers the forefoot and the ankle areas, as can be seen in Figure 1.
  • a welding line 3 running in the longitudinal center plane of the foot forms two air chambers 4 and 5, which can be seen in the circuit according to FIG. One of these air chambers, namely the air chamber 4, can also be seen in FIG. 3.
  • a rubber body 102 which defines a dome-shaped pump chamber 104, is vulcanized onto the film 18a.
  • This pump chamber 104 is closed by the vulcanization of a connecting flange 106 of the rubber body 102.
  • a first check valve 110 which acts as an air intake valve, is provided on the dome 108.
  • An expansion 112 of the flange 106 accommodates the valve units, generally designated 114 and 115, which are identical to one another and of which only the valve unit 114 is shown in FIG. 3.
  • This valve unit 114 comprises a valve housing 116.
  • the valve housing 116 has a main valve chamber 118 which widens and extends at its upper end an internal thread 121 is provided.
  • a bore 120 leads from the main valve chamber 118 through an opening 122 of the flange extension 112 to an air chamber connection opening 124 of the air chamber 4. Furthermore, a line 126 leads radially from the main valve chamber 118 to the pump chamber 104. This line 126 is formed by a fitting into the valve housing 116 Nipple 126a and a cap 126b pressed onto this nipple 126a, a second check valve 128 being accommodated between the nipple 126a and the cap 126b, which prevents the air chamber 4 from being emptied after the pump chamber 104.
  • a main valve body 130 is accommodated in the main valve chamber 118, which is provided with an external thread 132 in its central region and is screwed to the internal thread 121.
  • the main valve body 130 faces a valve seat 134 of the valve housing 116, which surrounds the bore 120.
  • a main seal 136 is assigned to the valve seat 134.
  • a sliding seal 138 of the main valve body 130 bears against the peripheral wall of the main valve chamber 118.
  • the main valve body 130 is secured against loss by a spring ring 140, which penetrates a slot 142 of the valve housing 116 and engages in an annular groove 144 of the main valve body 130.
  • a vent valve chamber 146 is formed within the main valve body 130 and receives a vent valve body 148.
  • a vent valve bushing 150 is inserted into the upper end of the vent valve chamber 146 and provides a vent valve seat 151 for a valve cone 152 of the vent valve body 148.
  • This vent valve cone 152 is biased against the vent valve seat 151 by a helical compression spring 154.
  • An actuation shaft 156 of the vent valve body 148 projects over the upper end of the vent valve bushing 150 and the main valve body 130 in front.
  • a knurled cap 158 is snapped onto the main valve body 130 and rotatably encloses the upper end of the valve housing 116 relative to the latter.
  • the cap 158 is designed at its upper end with a membrane 160 which can be curved downwards by finger pressure, so that the vent valve cone 152 can be lifted off the valve seat 151 by pressure on the actuating shaft 156.
  • the main valve body 116 is screwed upwards by means of the cap 158, so that the interior of the air chamber 4 is connected to the line 126 via the valve seat 134.
  • the vent valve cone 152 rests on the valve seat 151 under spring pressure.
  • the main valve chamber 118 is sealed from the atmosphere by the sliding seal 138.
  • the first check valve 110 closes and the second check valve 128 opens, so that air is pushed into the air chamber 4.
  • This air cannot return to the pump chamber 104 during the subsequent expansion of the dome 108 because of the second check valve 128, but new air is sucked in through the first check valve 110.
  • the air chamber 4 can be inflated to the desired pressure by repeatedly pressing the dome 108.
  • the main valve body 130 is screwed down again, so that the air chamber 4 is completely sealed off by the main valve body 130, the valve seat 134 and the seal 136.
  • the cap 158 with the main valve body 130 is screwed up again, so that the interior of the air chamber 4 communicates with the main valve chamber 118 via a radial bore 164 with the vent valve chamber 146.
  • the B is etuschistsschaft 156 pressed down so that the air can from the interior of the air chamber 4 escape through the bore of the vent valve bushing 150 into the interior of the cap and from the interior of the cap through the gap between the cap 160 and the valve housing 116. If the desired, reduced pressure is reached, the main valve body 130 is screwed down again.
  • FIG. 4 shows the installation of the assembly consisting of the rubber body 102 and the two valve units 114, 115 in an opening 92 in a material layer 32.
  • This layer of material can have considerable wall thickness, so that part of the pump valve unit is received by the opening 92 and protrudes only insignificantly over the layer of material, as can be seen from FIG. 1.
  • Corresponding windows for accommodating the rubber body 102 and the valve units 114, 115 can be provided in the outer shoe.
  • the two air chambers 4 and 5 cover the forefoot area and the ankle side areas.
  • the ankle side areas K are welded 6 and 7 annular sub-chambers 8 and 9 formed as parts of the air chambers 4 and 5. It should be noted that the film areas have remained within the weld seams 6, 7, so that the stability of the films is improved even when not inflated.
  • FIG. 5 shows a circuit of the pump chamber, the air chambers and the valve units 114, 115 in the event that two air chambers 4, 5 are supplied by a common pump chamber 104.
  • the air chamber 5 When the air chamber 5 is to be inflated, the main valve body 130 of the valve unit 114 sits on the seal 136 and the valve seat 134, while the main valve body 130 of the valve unit 115 is lifted off the seal 136 and the valve seat 134.
  • the pump chamber 104 is pushed in, the air from the pump chamber 104 enters the air chamber 5.
  • a backflow from the air chamber 5 into the pump chamber 104 is prevented by the second check valve 128 of the pump unit. Air is also prevented from escaping through the vent valve 151, 152. If the air chamber 5 is to be vented, only the vent valve 151, 152 needs to be actuated.
  • the air chamber 4 is to be inflated or deflated.
  • the main valve bodies 130 of both valve units 114, 115 are pressed onto the respective valve seat 134 and the seal 136.
