Definitions

  • the present invention relates to a tongue for shoes according to the preamble of
  • Claim 1 which is essentially a rigid, stable tongue and yet which evenly distributes a pressure caused by lace to a back of the foot which has padding towards the back of the foot and preferably at least one ventilation channel,
  • PCT / EP2010 056 022 by the same Applicant, the contents of which are incorporated herein by reference, describes an improved tongue and lace system for footwear which has improved conformability and improved uniform pressure distribution on the foot, with the boot opening the lace can rise completely and the opening and closing is easy to use.
  • the degree of adjustment of the pressure distribution along the back of the foot can still be improved and easily leads to bruises and pain.
  • a tongue for shoes which overcomes the drawbacks of the prior art and which for the purpose of pressure distribution through a lacing, has a rigid, firm structure as well as a structure adapting to an individual back of the foot also on the individually shaped back of the foot exerts a uniform pressure distribution and ensures a secure fit in the shoe.
  • the tongue according to the invention has a centering effect, so that slipping on the instep is avoided.
  • Another object is to provide in the tongue preferably a ventilation function for the shoe.
  • Tongue provided for shoes which consists partly of a rigid tongue of a relatively firm material, which is deformable by corresponding slots segment-like through the remaining joints and thus thus adapts elastically to a back of the foot with an individual shape segmentally.
  • the tongue comprises a padding towards the foot, which softly distributes the pressure forces of the rigid tongue segments towards the foot.
  • the padding according to the invention has an inner longitudinal slot, which is aligned with an inner longitudinal slot of the rigid tongue and congruent, thus providing an escape path for water vapor from the inside of the shoe.
  • the rigid tongue comprises a rigid outer tongue portion and a rigid inner tongue portion disposed thereunder spaced apart by spacers and thus together form a ventilation channel between the rigid outer tongue portion and the rigid inner tongue portion.
  • the vent passage communicates with the ambient air through at least one perforation of the outer tongue portion at its distal end such that chimney effect is achieved by the cold air from the outside along the ventilation channel and water vapor from the foot below the rigid inner tongue portion up through the ventilation channel can be deducted proximal end.
  • Fig. 1 is a plan view of an embodiment of a rigid tongue part of a
  • FIG. 11 is a plan view of another embodiment of a rigid tab portion of a tongue for a shoe having lateral indentations, an inner longitudinal slot, associated inner transverse slots and apertures in the tongue portion.
  • Figure 11 is a plan view of another embodiment of a rigid tab portion of a tongue for a shoe having lateral indentations, an inner longitudinal slot, two lateral inner longitudinal slots, and associated inner transverse slots.
  • FIG.. 3 is a perspective view of FIG .. 3, in which the proximal end face of the tongue is visible.
  • FIG. 1 is a side view of Fig., 3 and Fig. 4a seen from the front side of the tongue and when the tongue is pressed flat, so that essentially only the planar composite structure of the tongue at the proximal end side is visible.
  • FIG. 1 is a side view of Fig., 3 and Fig. 4a seen from the front side of the tongue and when the tongue is pressed flat, so that essentially only the planar composite structure of the tongue at the proximal end side is visible.
  • FIG. 1 is a side view of Fig., 3 and Fig. 4a seen from the front side of the tongue and when the tongue is pressed flat, so that essentially only the planar composite structure of the tongue at the proximal end side is visible.
  • FIG. 1 is a side view of Fig. 1, below which a padding in tongue form is seen.
  • Figure 11 is an exploded top view of the essential parts of another embodiment of a tongue consisting of a first rigid tongue portion (top), an underlying second rigid tongue portion with cylindrical spacers (center) mounted thereon, and a pad portion (bottom).
  • FIG. 6 is a side view of FIG. 6, in which the proximal end face of the tongue with open channels between the first rigid tongue part and the second rigid tongue part is visible.
  • FIG. 1 shows an embodiment according to the present invention illustrating a rigid tongue piece 1 as an integral part of a tongue for shoes which preferably has an elongate and substantially axisymmetric shape with respect to a sagittal longitudinal axis of the tongue.
  • deviations in the axial symmetry are preferably present, as it also corresponds to differences between a right and a left foot.
  • the tongue according to the invention can advantageously be designed as a left or right tongue.
  • the rigid tongue part 1 has an upper, proximal end 2 and a lower, distal end 3.
  • Preferably lateral notches 4 are introduced laterally in the upper third of the proximal end 2 on both sides, which, together with a preferably introduced upper inner transverse slot 8 on flexible material webs 5 remaining therebetween, ensure increased flexibility of the rigid tongue part 1.
  • lateral indentations 4 in particular two lateral notches on the right and left, introduced, seen to the longitudinal axis can stand a material web 5, which is so dimensioned that thereby also in the lower third of the tongue a sufficient flexibility of the rigid tongue part 1 is ensured. Due to the lateral notches 4, it is thus ensured in practice when the shoe is worn that the tongue and accordingly the rigid tongue part 1 of a curve shape can be individually adapted along a contour line of the foot rest, since this is also made more difficult mechanically as the tongue resp in that the rigid tongue part 1 is curved about its longitudinal axis by being pressed around the dorsally sloping back of the foot on both sides.
  • the tongue must therefore at a curvature about its longitudinal axis, which corresponds to the bilaterally laterally sloping back of the foot, yet have a flexibility along the longitudinal axis, which corresponds to the contour line of the foot spine.
  • the lateral notches 4 may preferably have an outwardly flared, substantially triangular shape, depending on the application and on the shoe.
  • areas of the material webs 5 are designed so that they have a thinner material thickness than the rest of the rigid tongue part 1, thereby increasing in these areas, both the flexibility, and the risk of breakage is reduced.
  • Longitudinal slot 6 of certain width, which preferably extends from the distal third to the proximal third along the central longitudinal axis introduced.
  • the inner one has Longitudinal slot 6 has a function to make the rigid tongue part 1 more flexible about its longitudinal axis, so that it can better adapt to the back of the foot, which falls laterally from its sagittally oriented contour line laterally ..

  • a tongue construction with a rigid tongue part 1 is a tongue which is stable along the longitudinal axis and non-stretchable, but which nevertheless is flexibly deformable in itself in order to be able to adapt to the individual shape of the foot bridge. Further embodiments with more or less of the above-mentioned, longitudinal and transverse recesses are conceivable and adapt to the respective shoe

  • the padding 14 supports a soft, substantially uniform pressure distribution of the various segments of the rigid tongue part 1 described above on the instep. Since the back of the foot has anatomically-related irregularities, especially along the contour line of the sagittally running back of the foot, the padding 14 is at these locations preferably designed particularly thicker. Accordingly, a preferred padding 14 in the middle along the longitudinal axis of the tongue is made particularly thick laterally from the inner longitudinal slot 14a and sloping down to the lateral edges. It is also conceivable that the padding 14 has substantially the shape of the rigid tongue part 1, but in addition also has lateral lobe extensions, which are pitched up on the tongue part 1 and sewn there, glued or the like.
