Abstract

The midsole body (10) has air inlet openings 22 in the heel area (16) and air outlet openings (28) in the midfoot area (24) and / or ball-toe area (26). The air inlet openings (22) are connected to the air outlet openings (28) via a ventilation channel (30). This is covered by means of a resilient under load while walking elastic in the direction of the outsole out cover. When walking with such a shoe bottom air ventilation is enforced as a result of rolling and thus heat dissipated from the shoe bottom.

Description

  • The present invention relates to a shoe bottom according to the preamble of claim 1 and a walker with a shoe bottom according to claim 13.
  • A special shoe floor construction for walkers is known under the name "Masai Barefoot Technology", MBT for short, and also under the label Swiss Masai. Characteristic of the MBT is a convex in the direction of rounded sole shape with an inserted soft heel part, the so-called "Masai sensor". The midsole has a reinforcing element integrated into it - called a "shank" - which reinforces the midsole so that it is also substantially rigid in its section located above the heel area. Due to the thus intentionally soft and destabilizing made shoe bottom construction of MBT walker loses the foot for the physiological locomotive characteristically support and support. This affects larger parts of the support and support muscles because the body must now be actively kept in balance. Due to the constant need for minimal balancing movements and adjustments of the foot musculature in search of a secure footing, MBT walkers wear a kind of permanent coordination training and stress additional parts of the skeletal musculature. In particular, neglected muscles are trained, the posture and gait are improved, and the body is toned and shaped. Furthermore, the wearing of MBT walkers in back, hip, leg and Foot complaints, help with joint, muscle, ligament and tendon injuries, as well as relieve hip and knee joints. On the one hand, the MBT walker leads to a greater circulation and thus heating of the foot and on the other hand, the shoe bottom has a considerable thickness with correspondingly good thermal insulation properties. It is therefore a need to provide a shoe bottom which is capable of dissipating heat more efficiently.
  • The same need also exists for shoe bottoms of other construction, especially shoe bottoms for sports shoes. For example, shoes from the Adidas "ClimaCool" series have air holes on the sole.
  • It is an object of the present invention to provide a shoe bottom with improved heat dissipation properties.
  • This object is achieved with a shoe bottom, which has the features of claim 1.
  • A midsole body has at least one air inlet opening in the heel area and air outlet openings in the midfoot area and / or in the ball and toe area. The air inlet opening and the air outlet openings are connected to each other by means of a ventilation channel. This is on the side facing away from the outsole of the midsole body - on the top - covered with a cover. This is elastic under the load while walking, towards the outsole, yielding. Since the cover is elastic, it goes back to its original shape when relieved.
  • As a result of the rolling movement while walking, a constant exchange of air thus inevitably takes place in the shoe bottom, which leads to improved heat dissipation. The thus forced air ventilation causes air enters through the air inlet opening in the shoe bottom and exits at the air outlet openings, which counteracts a damming of heated air under the foot.
  • By the compression of the sole bottom, or its cover when placing the heel, the heated air in the ventilation channel, according to the subsequent rolling movement, pressed through the air outlet openings. In the course of the rolling movement of the heel area is relieved, which leads to the suction of fresh air through the air inlet opening in the ventilation channel. An optimal for this purely mechanical principle rolling movement and the associated optimal air ventilation is achieved with shoe bottoms according to claim 9. With conventional shoe bottoms such efficient air ventilation would not be achievable.
  • Further preferred embodiments of the inventive shoe bottom are specified in the further dependent claims.
  • The invention will be explained in more detail with reference to embodiments illustrated in the drawings. It shows purely schematically:

    in a perspective view of a reinforcing element of the embodiment according to the 8 and 9 ,
  • Fig. 1 It shows in a plan view of a midsole body 10 of a midsole 12. It has in one, seen in the direction L, the rear portion 14 of a heel region 16 both on the shoe bottom inside 18 and on the Schuhbodenaussenseite 20 each an air inlet opening 22. Under shoe inner side 18 is the other shoe bottom of a pair facing side and with shoe bottom outside 20 to understand the side facing away from the shoe bottom.
  • Furthermore, the midsole body 10 has a midfoot region 24 and a ball-toe region 26, both on the inside of the shoe bottom and on the outside of the shoe shoe each five air outlet openings 28. In the direction of travel L, the midfoot region 24 connects to the heel region 16 and the ball toe region 26 to the midfoot region 24, each of these regions extending approximately over one third of the length of the shoe bottom.
  • The air inlet openings 24 and the air outlet openings 28 are connected to one another via a ventilation channel 30 formed by a depression in the midsole body 10. This has in the heel region 16 on a heel portion 32 with two legs 34 arranged in a V-shape. Each of these legs 34 leads to one of the two air inlet openings 22. Following the heel section 32, the ventilation channel 30 has a distributor section 36, whose channel trunk section 38, which is connected to the legs 34 of the heel section 32, extends in the shoe longitudinal direction S as far as the ball-toe area 26. In the direction perpendicular to the shoe longitudinal direction S seen the channel trunk portion 38 is offset with respect to the shoe center in the direction of the shoe bottom inside 18 to extend below the inner spine.
  • Channel channel sections 40 branch off from the channel trunk section 38 on both sides, wherein each of these channel channel sections 40 extends to one of the air outlet openings 28.
  • Both the air inlet openings 22 and the air outlet openings 28 have a width of preferably at least 4 mm and a length which is preferably at least twice as large as said width. Accordingly, also the Ventilation channel 30, measured in a direction perpendicular to the overhead, footbed surface 42 of the midsole body 10, with respect to this a depth of preferably at least 4mm. The width of the ventilation channel 30 is preferably greater everywhere than the depth, preferably at least twice as large.
  • On the side of the surface 42 of the ventilation channel 30 is covered by an elastically resilient cover 52, which in Fig. 1 not shown, to which, however, preferred embodiments in connection with the FIGS. 4 to 6 are described.
  • Fig. 2 shows in side view a midsole 12 of the shoe bottom, the midsole body 10 in the rear portion 14 of the heel 16 - on both sides - an air inlet opening 22 and in the midfoot area 24 and ball-toe area 26 total 4 air outlet openings 28, which in the shoe longitudinal direction S consecutively and in succession their inclination and length are arranged like scales overlapping. The air inlet opening 22 and the air outlet openings 28 are corresponding to a ventilation channel 30 Fig. 1 fluidly connected to each other; this has four Kanalastabschnitt 40 on both sides.
  • The midsole body 10 has on its underside, which faces an outsole 44, a heel recess 46, in which a heel piece 48 is disposed. This extends, viewed in the shoe longitudinal direction S, from the rear portion 14 of the heel region 16 to approximately in the middle of the midsole 12 and extends over the entire width of the Midsole 12 having a least approximately constant cross-section in the shape of a convex-convex lens. The soft heel part 48 and the midsole body 10 hold the outsole - in the unloaded state - in a continuously convex in the shoe bottom longitudinal direction S rounded shape, as is well known from MBT walkers. The soft heel part 48 has a maximum thickness of about 20mm. Accordingly, the largest thickness of the midsole body 10 is about 30mm.
  • At this point, it should be mentioned that the midsole body 10 has a peripheral bead 50, which protrudes in the direction of the surface 42 in the direction of the top. This serves on the one hand for fastening the midsole 12 to a shaft 56 and on the other hand, in the recess bounded by the surface 42 and the bead 50, the above-mentioned cover 52 is arranged.
  • The soft heel part is preferably made of an open-pore polyurethane elastomer foam (PUR Shore 30 C) and the midsole body 10 made of a polyurethane elastomer (PUR Shore 58 C) or an ethylene vinyl acetate (EVA); this applies to all embodiments shown.
  • Fig. 3 shows a midsole 12 of the shoe bottom, which is the same as the one according to Fig. 2 However, now that the air inlet openings 22 and the air outlet openings 28 are formed oval and run in a row behind one another in an upper edge region of the midsole body 10. Again, the air inlet openings 22 and the air outlet openings 28 via a corresponding ventilation channel 30 are interconnected.
  • The elastically deformable cover 52 for the ventilation channel 30 is preferably formed by an insole 54, which is placed on the upper surface 42 of the midsole body 10 and extends on all sides to the bead 50 and the middle of the body 10 attached to the bead 50 and abutting shaft extends ,
  • In the Fig. 4 shown embodiment of the insole 54 has an overhead, air-permeable support layer 58, from which in the direction towards the bottom, in the installed state on the midsole body 10 to, in a grid and at a distance from each other arranged support members 60 protrude. These are preferably formed in a double-cone shape and made of an elastic plastic. They thus adapt optimally to the depressions in the midsole body 10. When installed, they rest with their free end on the midsole body 10.
  • Another embodiment of the insole 54 is in Fig. 5 shown. It also has an overhead, air-permeable support layer 58. From this stand in the direction of down wavy shaped, elastically deformable support bands 62 from. These preferably extend in a direction perpendicular to the support layer 58 and mutually parallel planes. In the installed state, the support bands 62 are located on the midsole body 10 with the carrier layer 58 facing away from wave crests.
  • The support elements 60 or the support belts 62 thus form an elastically yielding support layer 64 for the support layer 58.
  • At the in Fig. 6 shown, particularly preferred embodiment of the insole 54, the support layer 64 is designed as a spacer fabric 66. The upper side forms the air-permeable carrier layer 58 and from this extend elastically deformable pile threads in the direction towards the bottom, also called spacer threads. Knitted fabrics of this type are produced for example by the company Müller Textil GmbH, Wiehl-Drabenderhöhe (DE) and marketed under the name "3mesh". Possible embodiments of the spacer knitted fabric 66 are, for example, in EP 1 775 362 A and EP 1 860 218 A disclosed.
  • In the FIG. 7 is, in perspective exploded view, according to a preferred embodiment of the shoe bottom Fig. 2 shown. The midsole body 10 is provided with the heel recess 46. The soft heel part 48 is inserted into the heel recess 46, in the present case space-filling. The outsole 44, as known from MBT walkers, is attached to the midsole body 10 and heel piece 48, thereby maintaining it in the convex shape, cf. FIGS. 2 and 3 , It consists for example of rubber and has a Shore hardness A 55 - 65 on.
  • A ventilation insert element 68, which in the Fig. 7 is shown detached from the midsole body 10, but is integrated into this. Seen in plan view, the ventilation insert member 68 has a U-shape, wherein the two parallel legs 70, 70 'extend in the shoe bottom longitudinal direction S and at their, seen in the direction L, the rear end via an arc portion 72 are interconnected. The two legs 70, 70 'and the arc portion 72 are formed by a cross-sectionally U-shaped channel wall 74, wherein this channel wall 74 in the region of the legs 70, 70 'per a channel trunk portion 38' limited. The legs 70, 70 'and the curved section 72 are open in the direction towards the top on the side facing away from the outsole 44. The channel wall 74 forms a bottom part 76 and an inner wall part 78 and an outer wall part 80, wherein these two wall parts 78, 80 project from the bottom part 76 in the direction towards the top. In the heel region 16, the depth of the U-shaped cross section, measured from the free edge of the wall parts 78, 80 bis to the bottom part 76, preferably at least 4mm. Further, the wall parts 78, 80 are preferably at least 8mm apart. In the midfoot region 24, the said depth increases according to the shape of the heel recess 46 and then, in the direction towards the front end in the direction L, decreases continuously.
  • In the curved portion 72, which comes to lie in the integrated state in the rear portion 14 of the heel 16, stand from the outer wall portion 80 in the direction against the shoe bottom inside 18 and toward the shoe bottom outside 20 per an air inlet tube stub 82. These are fluidly connected to the channel trunk sections 38 'and their outer free ends form the air inlet openings 22.
  • Accordingly, in the midfoot region 24 and ball-toe region 26 from the outer wall portion 80, in the direction of the outside, air outlet pipe stub 84 from. These are also associated with the associated channel trunk section 38 ' fluidly connected, form the Kanalastabschnitte 40 and with their free ends, the air outlet openings 28th
  • The ventilation insert element 68 is preferably made of TPU Shore 85 A by injection molding.
  • Fig. 7 further shows a reinforcing element 86, which has such a stability at least in the heel region 16 and midfoot region 24 that the midsole 12 is at least approximately resistant to bending in its section located above the soft heel part 48, with respect to loads during standing and walking. In the integrated state in the midsole body 10, the reinforcing element 86 is encompassed by the ventilation insert element 68. The reinforcing element 68 is thus, seen in the direction perpendicular to the shoe bottom longitudinal direction S, in a central region of the midsole body 10, wherein in the direction against the shoe bottom inside 18 and in the direction against the shoe bottom outside 20 each one of the two channel trunk sections 38 'is arranged.
  • The reinforcing element 86, which is also preferably produced by injection molding, has an overhead, tongue-shaped, plate-like support member 88 and one of this, in the direction towards below projecting, V-shaped support member 90. Both the support member 88 and the support member 90 are double-walled, wherein the two walls are fixedly connected to each other via ribs 92. The support member 82 is located in the midsole body 10 integrated state close to the surface 42, as the midsole body 10 in Fig. 7 suggests; Here, the reinforcing element 86 is already in Midsole body 10 integrated. It extends between the two legs 70, 70 'from the inner wall portion 78 in the arch portion 72 in the direction L forward against a front portion of the ball-toe portion 26. Preferably, the reinforcing member 86 in the heel region 16 and midfoot region 24 is rigid and for example, made of nylon 12, while it may be flexibly formed in the ball-toe area 26 and consists for example of TPU.
  • The support member 90 is also formed stably, wherein seen in the direction L, rear leg 90 'of the support member 90 is formed according to the heel recess 46 and this rear leg 90' with the front leg 90 "when seen in the direction L, front Meet the end of the heel recess 46 and form a tilting edge 94 there.
  • The prefabricated reinforcing element 86 and the prefabricated ventilation insert element 86 can be inserted into a cavity of an injection mold for spraying the midsole body 10, wherein after closing the mold, for example PUR Schor 58 C is injected for molding the midsole body 10. In this case, the injection molding tool support ribs for the channel wall 74 and in the Lufteintrittrohrstummel 82 and the air outlet pipe stub 84 engaging slide to prevent compression of the Ventilationseinsatzelements 86 during injection molding of the midsole body 10.
  • As a result of the exploded view, the in the Fig. 7 shown midsole body 10 for Ventilation insert element 68 against the same shaped recesses and passages on.
  • Next shows Fig. 7 the insole 54, which forms the cover 52, which acts on the surface 42 formed by the midsole body 10, possibly the reinforcing element 86 and the exposed end face of the outer wall part 80 and inner wall part 78.
  • On the circumference, the insole 54 is encompassed by the relatively high-trained bead 50. Preferably, the support layer 58 of the insole 54 is formed like a footbed and the thickness of the support layer 64 is adjusted accordingly. Further, the surface 42 between the outer wall portion 80 and the bead 50 has a continuous belt-like surface portion 42 'on both the shoe bottom interior 80 and shoe bottom side 20 such that the support layer 64 circumferentially extends along the bead 50 above the reinforcement member 86 to a broad center portion is supported over the entire length of the midsole body 10.
  • The 8 and 9 show a further possible embodiment of the reinforcing member 86 for a midsole 12 according to the Fig. 2 or 3 , which correspond with a ventilation channel 30 Fig. 1 is trained. In Fig. 10 the reinforcing element 86 is shown in perspective obliquely from above. Its task is exactly the same, as above in connection with the embodiment according to Fig. 7 described and known from MBT walkers forth. In the 8 and 9 the outlines of the midsole 12 are indicated and the reinforcing element 86 darkened.
  • In the heel region 16, the planar reinforcing element 86 runs in the midsole body 10 along the heel recess 46 and in the midfoot region 24 and in a, viewed in the direction L, rear portion of the ball-toe region 26 in the interior of the midsole body 10 at a distance below the ventilation channel 30. Da Wall thickness of the midsole body 10 between the heel recess 46 and the surface 42 in the heel area 16 is much smaller than in the midfoot area 24 and ball-toe area 26, the use of known from MBT walkers reinforcing element 86 could lead to insufficient depth of the ventilation channel 30 in the heel section 32. This is especially clear Fig. 9 where the ventilation duct 30 is shown grayed out. In order to counteract the mentioned disadvantage, the reinforcing element 86 in the heel region 16 has a channel-like recess 96 which corresponds to the heel section 32 and is V-shaped in plan view. In order nevertheless to ensure the necessary bending stiffness of the reinforcing element 86, the latter can have, for example, support ribs running along the webs 100 separating the passages 98 on the underside. Even if they protrude into the soft heel part 48, the behavior of the shoe bottom or its properties is not changed as a result of their low height. It is also possible to form the recess element 86 in the heel region 16 of a more stable material.
  • According to a shoe bottom Fig. 7 it is conceivable not to use a ventilation insert element 68, but from the recess for forming the channel trunk sections 38 'and their connection in the arc section 72 by a rib Injection mold, and form the Kanalastabschnitte using slides directly on the midsole body 10.
  • When walking with a shoe bottom shown in the figures and described above is on the one hand the heel area 48 compressed on the one hand, which greatly reduces shocks on the body of the user used, and on the other hand, the cover 52 in the heel area 16 in the direction of the midsole body 10th too deformed. This leads to a local narrowing of the midsole 10 and the cover 52 and its support layer 58 limited, filled with air cross-section. As a result of rolling on the ground, this narrowed cross section in the direction of L moves over the midfoot region 24 into the ball-toe region 26. This migration of the constriction from the heel region 16 into the ball-toe region 26 results in the expulsion of air from the ventilation channel 30 through the air outlet openings 38, while after tilting about the tilting edge 94, or through the midsole body 10 at the front end of the heel recess 46 formed in the heel region 16, resulting in the elasticity of the cover 52 and the insole 54 behind the constriction again leads to an extension of the cross section, whereby fresh air into the ventilation channel through the air inlet openings 20 30 is sucked. When walking is thus promoted by the midsole 12 on a purely mechanical principle air ventilation. Through this heated air is expelled through the air outlet openings 28 while fresh, cool air is sucked through the air inlet openings 22.
  • If the cover 52 or insole 54 is permeable to air, cool air is further forced against the foot of the user.
