Definitions

• the invention relates to a shoe sole with elastic properties in the vertical direction.
• stiffening elements are provided in known shoes which reduce buckling of the shoe upper relative to the shoe sole. This is especially true for shoes with high heels known, e.g. B. in mountain shoes or basketball shoes.
• the mobility of the foot relative to the lower leg is severely restricted by the raised, stiffened shafts. In the case of shoes with a low shaft, such a stiffening is almost ineffective if the shoe shaft does not enclose the ankle.
• the shoe sole When the shoe sole is loaded with transverse components, as occurs in sport with abrupt lateral movements, the shoe sole will usually deflect asymmetrically. This means that the elastic sole material will give way more in the most stressed places, so that the insole on the foot is no longer parallel to the ground. Due to the stabilization device provided according to the invention between the upper and lower sides of the sole, which reduces lateral tilting of the upper side of the sole compared to the lower side of the sole in this partial area when the sole is subjected to pressure, the insole and thus the sole of the foot are kept as parallel as possible to the floor the bending angle of the ankle is reduced and the risk of overpronation or oversupination is reduced.
• the shoe sole according to the invention can be used with advantage particularly in sports shoes, which often have a very soft sole, in that it is no longer necessary to support the ankle joint by a raised, stiffened shoe upper.
• the stabilizing device according to claim 2 is provided in the heel area.
• the stabilizing device has a torsionally rigid body which is advantageously embedded in elastic sole material.
• the stabilizing device can advantageously be designed as an insert, wherein this insert can be provided interchangeably.
• the stabilizing device is to be used in combination with a ventilation system located in the shoe sole for ventilating the shoe with fresh air.
• the torsionally rigid body of the stabilizing device is preferably made of metal, e.g. B. steel or from a suitable plastic.
• the stabilization device is part of a midsole, that is to say worked out of the midsole material.
• This stabilization device offers the great advantage that no additional material is required.
• the stabilizing device can also be very easily combined with the ventilation system.
• Figure 1 shows a cross section of the invention
• Shoe sole in its longitudinal direction and seen only in the heel area along line I-I of FIG. 2, which is designed with a first exemplary embodiment of a stabilizing device
• FIG. 2 shows a top view of the shoe sole part shown in FIG. 1,
• Figure 5 shows a section along the line V-V of the
• FIG. 6 shows a further embodiment of the shoe sole according to the invention in cross section and along line VI-VI of FIG. 7,
• a shoe sole 10 shown in the drawing consists of an outsole 12, an insole 14 and a midsole 16 located between the outsole and insole.
• the midsole 16 has a recess 18 in the heel area for receiving a stabilizing device 20.
• the stabilization device 20 consists of a torsionally rigid body 22 made of, for example, metal or plastic, which is embedded in spring-elastic material 24.
• the body 22 consists of two elongated, parallel support arms 26 which change their position when subjected to pressure and which are connected to one another via a largely torsionally rigid connection 28.
• the support arms 26 are located in the left or right sole edge region. The support arms 26 close without pressure load through the heel an acute angle d-. with the flat side of the sole, which diminishes under pressure.
• the torsionally stiff connection 28 always results in an essentially parallel position of the support arms 26 with any pressure load on the heel region of the sole, so that the insole 14 by means of the stabilizing device 20 lies essentially parallel to the outsole 12 even when the left and right sole edge regions are loaded unevenly .
• the body 22 as shown in FIGS. 1 and 2, has the shape of a U-shaped bracket 30, the two U-legs 32 of which form the support arms 26.
• the torsionally rigid body 22 is a rectangular frame 50, for example made of wire or plastic, in which two opposite frame legs 51 form the support arms 26.
• the frame legs 51 are connected via frame parts 52 and 54, which form the torsionally rigid connection 28.
• the stabilization device 20 shown in FIG. 3 has two rectangular frames 50.
• the frames 50 are arranged symmetrically with respect to a plane perpendicular to the longitudinal direction and flat side of the sole, the upper frame parts 52, which form the torsionally rigid connections 28 and which lie on the upper side of the midsole 16, have a smaller distance from one another than the lower ones, which likewise form the torsionally rigid connection 28 Frame parts 54.
• This arrangement has the advantage that only slight displacements of the resilient material 24 occur on the upper side of the midsole 16 adjoining the insole 14.
• the torsionally rigid body is essentially angular, flat part formed, in which two opposite side areas serve as support arms.
• Such a torsionally rigid body could, for example, be inserted very simply into a slot provided in the shoe sole for receiving the body. This results in the possibility of being able to adjust the stabilizing device individually by simply exchanging the torsionally rigid body.
• the stabilizing device 20 has two pairs 36 of U-shaped brackets 38 which are embedded in the resilient material 24.
• the brackets 38 of a pair of brackets 36 have torsionally rigid bracket webs 40 and U-legs 42.
• the strap webs 40 of a pair of brackets 36 are arranged one above the other in the resilient material 24.
• the U-legs 42 of one of the brackets 38 arranged one above the other have ends 43 which are bent in parallel to the bracket web 40. These bent ends 43 are articulated to ends 44 of the other bracket 38.
• the articulated connection 48 lies approximately in the middle of the sole and the torsionally rigid connections 28, that is to say the stirrup webs 40, of the individual stirrups 38 are assigned to the top or bottom of the sole, so that the U-legs 42 forming the support arms 26 again form an acute angle with the flat sole side.
• This embodiment has the advantage that the support arms 26 are shorter than the support arms 26 of the embodiment according to FIGS. 1, 2 and 3, so that when the shoe sole 10 is compressed, a not so great displacement of the resilient material 24 in the longitudinal direction of the sole occurs.
• the strap webs 40 assigned to the upper or lower side of the sole practically only carry out vertical movements.
• the resilient material can have horizontal bores, not shown, which are arranged in layers which are offset from one another by a gap.
• the resilient material 24 forms an insert 56 which is introduced into the recess 18, as shown for example in FIG. 1.
• the insert 56 is shaped such that the recess 18 is not completely filled and a free space 58 remains.
• This free space 58 is also a pump space 60 for a ventilation system through which air can be conveyed into the interior of the shoe.
• the pump chamber is connected to the inside of the shoe in the heel region and thus to the atmosphere by means of a suction opening 62, which can be closed via a check valve 64.
• the pump chamber 60 When pressure is applied in the heel area, the pump chamber 60 is compressed and the air is conveyed into the inside of the shoe in the toe or ball area via at least one air duct 66.
• the free space 58 is also used to accommodate the movement of the lower frame parts 54 in the longitudinal direction of the sole.
• the torsionally rigid body 22 preferably consists of a different, much stiffer material than the shoe sole, for example made of steel or a high-strength plastic.
• FIGS. 6 and 7 show an embodiment in which the stabilization device 20 has no additional materials.
• the stabilizing device 20 is part of the midsole 16 in this exemplary embodiment.
• the support arms 26 are formed by the midsole material of the lateral edge regions 68 of the midsole 16.
• the midsole material located between the edge regions 68 is worked out in such a way that at least one flat chiges part 70 of the midsole 16 remains, which includes an acute angle with the flat sole side, which decreases under pressure.
• This flat midsole part 70 serves as a torsionally rigid connection 28 of the support arms 26.
• This embodiment of the stabilization device 20 does not act as effectively as the exemplary embodiments of the stabilization device 20 with a torsionally rigid body 22 made of steel or plastic, since here the torsionally rigid connection 28 consists of the elastic midsole material. However, this embodiment has the great advantage that no additional materials are required.
• the stabilization device 20 has two flat intermediate parts 70, which are connected to one another on the insole-side surface of the midsole 16 via a flat web 72 and which together with the outsole 12 delimit the pump chamber 60.
• the pump chamber 60 is part of the ventilation system, through which, as in the above exemplary embodiments, air can be conveyed into the interior of the shoe via the air duct 66 via the pump chamber which can be connected to the atmosphere by means of the suction opening 62 and which can be elastically deformed when subjected to pressure is.
