Definitions

  • the present invention relates to a shoe with a sole construction which during every step of the walking motion of a user enables efficient air circulation in the shoe, and thereby directly at the foot of a user of the shoe.
  • a shoe is composed of two main parts, namely the upper part called the upper, and the lower part called the base.
  • the upper can comprise an inner upper (lining), intermediate upper (interlining) and outer upper (vamp).
  • the base is composed of a sole and can comprise an inner sole (insole) and an outsole.
  • One or more midsoles can be provided between the insole and the outsole.
  • shoes are known that are equipped with devices in the sole which promote the circulation of air in the shoe, whereby the internal moisture in the shoe is to be reduced to improve foot comfort of the user of the shoe.
  • This known type of shoe generally provides hollow connections which are accommodated interconnected in the interior of the sole.
  • the air is in prior art via openings of the sole to be directed from the outside to the interior. The openings are sealed with membranes to protect against water.
  • WO 2008/158880 proposes a ventilation device for insertion into a shoe in which ventilation of an interior of the shoe into which the ventilation device is inserted is to be achieved by use of a rotatable pump hinged on a flange.
  • the ventilation device is with the movable pumping device very complex and in mechanical terms very susceptible to failure.
  • a sole construction having an upper sole part, a lower outsole part and an air-pumping device
  • the air-pumping device is formed either by a cavity substantially embedded in the upper sole part, or formed separately as an independent entity fully or partially embedded in a cavity of the upper sole part;
  • air can be discharged into the interior of the shoe through the air-discharging device due to the loading of the sole construction during the walking motion of the user, and where the air-pumping device can be compressed by a pumping volume corresponding to the amount of air discharged,
  • the pumping volume is at least 5 ml, in particular at least 10 ml.
  • the sole construction, or the upper sole part, the lower outsole part and the air-pumping device, respectively, are according to the invention configured such that it enables at least 5 ml, in particular at least 10 ml, of air (fresh air) to be sucked in from the outside (outside the sole construction or the shoe with the sole construction) during the expansion of the air-pumping device and at least 5 ml, in particular at least 10 ml, air is discharged into the interior of the shoe during the compressing of the air-pumping device. Only in this manner can significant ventilation of the interior of the shoe perceived by a user of the shoe be achieved. In contrast to prior art, the shoe according to the invention therefore enables efficient ventilation of the interior of the shoe.
  • the pumping volume of an air-pumping device is there for a respective predetermined sole construction determined as follows:
  • a PC-controlled machine PFI DSPM H 3035 (PFI Hydraulic Shock Absorption Testing Machine), to be acquired via the “Prüf-und Anlagensinstitut Pirmasens”, Marie-Curie-Stra ⁇ e 19, 66953 Pirmasens, is used for the procedure.
  • the contact pressure of the annular plunger with a diameter of 40 mm during the measurement of the pump volume according to the invention amounts to 1200 N.
  • the plunger is positioned as follows (see FIGS. 6 a to 6 d ).
  • the straight line g 1 along the lower outsole part with the greatest length of all straight lines extending from the outermost edge of the heel region of the lower outsole part to the outermost edge of the toe region of the lower outsole part is first determined.
  • the line s 1 perpendicular to the determined straight line g 1 is determined ( FIG. 6 a ).
  • the center M 1 of this perpendicular line s 1 with respect to points P 2 and P 3 at which it cuts the lateral edges of the lower outsole member is then determined ( FIG. 6 b ).
  • Straight line g 2 (first test axis) is then defined by points P 1 and M 1 .
  • Half the distance from P 1 to M 1 on straight line g 2 defines the center M 2 (positioning point) ( FIG. 6 c ).
  • the test plunger is positioned centrally on this center M 2 (positioning point). This is done, for example, by using a second test axis g 3 drawn in in addition to the first test axis g 2 and extending perpendicular to the first test axis g 2 and through its center M 2 (positioning point).
  • the radius of the test plunger can then be marked on test axes g 2 and g 3 ( FIG. 8 d ).
  • the outsole By slowly lowering the test plunger prior to the test, the outsole can be precisely positioned, where care is to be taken that the test plunger does not apply any pressure onto the material. If the position of the plunger corresponds to the markings drawn in, then the outsole part is fixed with brackets such that no movement of the outsole part is any longer possible.
  • An air intake tube, Festo (pneumatic 10 bar at RT) PUN ⁇ 8 ⁇ 1.25 (inner diameter: 8 mm/outer diameter: 8 mm) is introduced through an opening in the outsole part and completely sealed at the outsole.
  • An air-pumping device embedded in the heel region sucks in air through the air intake tube via an air intake valve.

  • the forefoot region of the sole construction is during the continuous load test sealed for examining the amount of air flow.
  • the air throughflow is measured using a Burkert mass flow meter Type 8701 with a nominal flow rate range from 1 l/min, to be acquired via Christian Burkert GmbH & Co. KG, Christian-Bürkert-Strasse 13-17, 74853 Ingelfingen.
  • the air can in exemplary developments of the shoe according to the invention be discharged in particular along air guides, such as channels or mesh fabric, of the sole construction which are connected to the air-pumping device, and via openings of the air guides (channels) in the interior of the shoe with the sole construction.
  • Mesh fabric is presently understood to be a textile or plastic insert with a net-like structure, for example, a so-called “MATATZEN” structure.
  • the air-pumping device can be formed substantially in the upper sole part.
  • the feature that the air-pumping device is formed substantially in the upper sole part means that the air-pumping device is at least by more than 50% formed in the upper sole part (and less than 50% in the lower outsole part), even if it may be overall formed by a cooperation of the upper sole part and the lower outsole part.
  • This feature can in particular indicate that the air-pumping device is formed in the upper sole part by at least more than 80%, in particular more than 90%, in particular more than 95%.
  • up, upper etc. refer to positions that are further distanced from a ground being contacted by the sole construction during use in a shoe than positions which are referred to by terms such as down, lower, etc.
  • the upper sole part can comprise channels connected to the air-pumping device being connected to the channels and formed substantially in the upper sole part. Air is then pumped by the air-pumping device along the channels. Openings can be provided along the channels in the upper sole part such that air flowing through the channels can pass through the openings to above the upper sole part, i.e. into the interior of a shoe. For example, the air can pass through a perforated insole into the interior of the shoe. Due to the pumping effect of the air-pumping device when the user applies pressure with his foot, air (at least 5 ml, in particular at least 10 ml) is then pumped through the channels and the openings provided therein for ventilation of the foot in the interior of the shoe in which the foot is located.
  • the lower surface of the lower outsole part therefore contacts the ground trodden on by a user of the shoe when using a shoe with the sole construction according to the invention.
  • Said first upper sole part and the lower outsole part of the sole construction can be formed separately, but they can also form parts of an integrally formed sole body so that they form an integral block.
  • air is by the air-pumping device sucked in from outside the sole construction and outside the shoe, in particular from above the upper sole part, and distributed in the channels.
  • the air-supplying device can there be led upwardly through a correspondingly provided opening of the upper sole part.
  • the air-pumping device is adapted to perform an air-pumping function in response to a walking motion of a user of the shoe with the sole construction according to the invention such that it alternatingly sucks in air (at least 5 ml, in particular at least 10 ml) via at least one air guide (air-supplying device) from the outside of the sole construction or the shoe, respectively, when the foot of the user relieves a load, and distributes the air (at least 5 ml, in particular at least 10 ml) via channels in the shoe when the foot of the user loads (puts weight on) the air-pumping device.
  • the air-pumping device can be provided from the heel region extending from the end of the foot to the Joint region, in the central joint region and/or the bail region (forefoot region), extending from the front end of the foot up to the joint region.

This portion is formed more resilient than the lower outsole part such that the air-pumping device is well compressible when being loaded (weight is put on) by the foot of a user. An efficient pumping effect can be achieved by this resilient configuration.
  • An efficient pumping effect is achieved due to the fact that the portion of the upper sole part in which the air-pumping device is formed is formed more resilient than the lower outsole part. When being loaded by the user's foot, this more resilient portion is pushed downwardly (towards the tread area) and can thereby operate the air-pumping device to the effect that it forces air from the air-pumping device and through the channels.
  • the pumping effect can be further enhanced in that the lower outsole part at the outer tread area (which in the course of a walking motion is in contact with the ground on which a user of a shoe with the sole construction according to the invention is walking) in the region of the air-pumping device comprises a raised portion which is adapted to be pressed in the direction of the upper sole part when being loaded by the user's foot.
  • the raised portion can be formed thinner than the other regions of the lower outsole part. Not only efficient air circulation is ensured by the fact that the raised portion is compressed during loading, but walking comfort is also increased due to the shock-absorbing function of the air-pumping device.
  • particularly efficient air ventilation of the shoe is in fact achieved by a combination of a) providing the air-pumping device, for example, substantially in the upper sole part, b) providing the portion of the upper sole part in which the air-pumping device is formed in such a way that it is more resilient than the lower outsole part, and c) providing the raised portion at the lower outsole part at the outer tread area in the region of the air-pumping device.
  • the air-pumping device is formed substantially by a cavity embedded into the upper sole part, or the air-pumping device is formed separately as an independent entity and is fully or partially embedded in a cavity of the upper sole part.
  • the volume content of the cavity formed in the upper sole part is greater than that which is provided by the lower outsole part when forming the cavity acting as the air-pumping device.
  • the cavity can in particular be formed in the upper sole part by more than 80%, in particular more than 90%, in particular more than 95%.

  • the air-pumping device as a separate entity can comprise a plastic pump reservoir. When it is loaded by the user's foot if is compressed whereby air is forced out of the plastic pump reservoir. When the plastic pump reservoir is during the walking motion again unloaded by the foot (weight is put off), then it expands and, due to the negative pressure previously generated, draws in air from the outside, which is then freshly available for subsequent ventilation of the interior of the shoe and thereby of the user's foot.
  • the air-pumping device can be integrally formed in one piece with the plastic pump reservoir and the air guides. Forming the air-pumping device as a separate entity allows selecting material and in particular material strength independent of the sole construction or the sole body, respectively.
  • tubes can also be provided from the air-pumping device along the channels in which air from the air-pumping device flows.
  • the tubes must have openings corresponding to those which can be provided in the upper sole part.

  • the sole construction can be formed around a separate independently formed air-pumping device such that the upper sole part is more resilient at least in the region of the air-pumping device (due to different thicknesses) than the lower outsole part.
  • the sole construction is in this case produced from resilient material, for example, by plastic injection molding.
  • the shoe described in the above examples can in the air-supplying device comprise a first valve that is configured such that it allows air to pass only in the direction from the outside of the sole construction info the air-pumping device and/or a second valve is arranged in the air-discharging device which is configured such that if allows air to pass only in the direction from the air-pumping device to the channels.
  • outside air can be sucked in by the air-pumping device, and the previously sucked-in air can be discharged to the air guides, for example, the channels.
