Sole and shoe for cross-country skis or telemark style skiing

FIELD: personal use articles.

SUBSTANCE: sole of shoe for cross-country skis or telemark style skiing consists of back part, which comprises shoe heel (13) and front part (12), having slightly cup-like shape. Sole (10) is wholly made of comparatively rigid material, preferably, plastic, and on the side of bottom in the area of front part (12) and/or in the area of back part (11) it is equipped with a layer (14) of protector from comparatively soft, preferably, rubber-like material. To improve bend elasticity, thickness of front part (12), which is on top fixed to shoe in the form of external layer, at least in the area of metatarsophalangeal section M is considerably reduced compared to other parts of sole (10), in particular compared to area (30) adjacent to metatarsophalangeal section M and diverging towards back edge of sole (10). Thickness of area (30) continuously increases, starting from metatarsophalangeal section (M) and stretching in direction of front part. As a result, elasticity of bend around axis, which is mostly transverse to longitudinal direction of sole (10) on metatarsophalangeal section M, achieves maximum value. Using sole of the invention, ski shoes were made with such a sole.

EFFECT: consists in the fact that relatively high longitudinal bend elasticity is achieved with preservation of proper side stability and simplicity of manufacturing.

The present invention relates to a Shoe sole for a cross-country ski or Shoe for skating style Telemark, which consists of the rear or heel part, which is the heel of the Shoe, and the front or toe portion slightly dished form, and the sole is entirely made of a relatively rigid material, preferably plastic, and is provided by the bottom located in the area of its front or its rear layer of the tread from a relatively soft, preferably rubber-like, material. In addition, the invention relates to a Shoe for cross-country skiing or Shoe for skating style Telemark with such a sole.

The soles of this type are well known. Shoes with this sole has for many years produced and sold by the company Rottefella AU (Rottefella AS) under the name "NNN". From the bottom (tread side) such soles have two longitudinal guide grooves and United with them transverse grooves, wherein the longitudinal guide grooves run along the entire length of the sole and interact with the response of the longitudinal guide ribs on the respective plate ski binding. From the bottom on the front end of the sole in the recess from the bottom has a transverse axis, which serves to swivel Shoe with ski attachment, provide the corresponding free lifting of the heel.

The above-mentioned longitudinal guide grooves formed not only in the layer of the tread, but also the soles. As a result, significantly reduced the Flexural elasticity of the sole, especially in planovalgus the soles. To solve this problem, EP 0787440 B1 was asked to run the sole of the sports Shoe of two parts, the rear of which is hard, and the front is made of soft material. The disadvantage of this solution is, however, impossible to make all sole entirely of the same material, for example, by injection molding. Therefore, the manufacturing of these shoes is associated with high costs.

To achieve good longitudinal flexibility while maintaining sufficient transverse rigidity in EP 0029206 A1 features a reinforced sole for shoes, made of the base material, in which the core material is inserted stiffening elements. To do this, the soles are made open in the area of the supporting part of the foot and arch of the foot, each of which has rocafuerte nests, made in the form of ribs, transversely across the corresponding window. These ribs is inserted stiffening profile that tells the sole high transverse rigidity. Obviously, such a reinforced outsole is also difficult to manufacture and therefore requires for the manufacture of b is increased costs.

In DE 4229039 C2 discloses another principle improve torsional rigidity and longitudinal elasticity of the Shoe for cross-country skiing. The basis of this principle the idea of modification of the insole to modify the properties of the boot. In particular, the insole is available in two different materials used for different parts of the insole. Since the effect of insoles on the mechanical properties of the entire Shoe is limited, then this solution does not give satisfactory results.

SN-C-557154 mainly refers to the heel of a boot for cross-country skiing, the construction of which is designed to prevent the buildup of snow on the heel.

Based on the foregoing, the present invention was based on the task of creating the soles of the Shoe for cross-country skiing or skating style Telemark, with a relatively high longitudinal Flexural elasticity while maintaining good lateral stability (torsional rigidity) and, in addition, for simplicity of manufacture. In addition, the purpose of the invention is to provide a Shoe for cross-country skiing or skating style Telemark with such a sole.

The task of ensuring the sole of the ski boot, with a range of challenging at the same time properties, is solved according to the invention in the sole and the Shoe, as claimed in the independent claims, while p is impactfully options for implementation are listed in the dependent claims.

Namely, the present invention features a Shoe sole for a cross-country ski or Shoe for skating style Telemark, having the back part on which the heel of a boot, and the front part, slightly dished form, and is entirely made of a relatively rigid material, preferably plastic, and from the bottom at the front part or the rear part having a layer of tread relatively soft, preferably rubber-like material, characterized in that the thickness of the front part, which the top is attached to the Shoe in the form of the outer layer in the area planovalgus plot significantly reduced in comparison with the rest of the sole, in particular in comparison with the area adjacent to planovalgus section and passing to the rear of the sole, and compared with the area adjacent to planovalgus section, the thickness of which continuously increases from planovalgus section and which extends toward the front side, so that the bending elasticity around the axis passing mainly crosswise to the longitudinal direction of the sole on planovalgus plot has a maximum value.

In accordance with this, the essence of the invention lies in the fact that the thickness of the front part, which shall be attached to the top of the Shoe in the form of n the outer layer in the region of planovalgus plot significantly reduced compared to the other surrounding areas of the sole, extending forward and backward, at the expense of what you can achieve maximum Flexural elasticity (elasticity) around an axis passing mainly transversely to the longitudinal direction of the sole in the area planovalgus plot. The boundaries curving region planovalgus area determined by this difference in thickness and this embodiment allows to clearly distinguish the area of the curve in the field planovalgus plot, which is reproducible in every ski step. This flexible region planovalgus plot does not pass in front of the sole. So, basically avoids the deformation (bending) of the sections of the front part of the sole and less wear on the borders of the area planovalgus plot. This provides a natural bend of the ski boot and feet, even if for the sole taken a relatively hard material, which provides the advantage that no additional means, such as ribs or stiffening inserts, to give the Shoe the desired longitudinal flexibility in combination with sufficient lateral stability. By reducing the thickness of the front part in the field planovalgus area compared with the rest of the sole, in particular in comparison with the region PR is lying to planovalgus section and passing to the rear edge of the sole, providing the maximum Flexural elasticity around the axis passing mainly transversely to the longitudinal direction of the sole in the area planovalgus site, you can create a sole, which, being attached to the Shoe, very little effect on the natural flexibility of the Shoe and feet, even when a relatively large rigidity of the material of the sole. At the same time, the proposed invention outsole gives the Shoe a high torsional rigidity and, thus, provides support for the legs, preventing injuries, and improves the functional characteristics of the ski boot. In addition, the proposed invention the sole can be relatively easily manufactured by injection molding, since the sole can be made of the same material, in particular plastic.

The so-called plasmapheresis area includes the so-called planovalgus the bending axis. Strictly speaking, plushophilia the bending axis defined by a line, and band gap, passing transversely to the longitudinal direction of the sole and, in particular, inclined at an angle to the longitudinal direction of the sole from the inside of the front out the back.

In a preferred embodiment, the thickness of the front of planovalgus the plot is 1 to 4 mm, more specifically from 2 to 3 mm. found that the thickness of this interval, the HEA is csim suited for most materials the soles from the point of view of the bending of the sole.

The thickness of the rear part between the heel of a Shoe placed on the rear end part, and planovalgus plot can be from 2 to 8 mm, more precisely from 3 to 6 mm. as a result, can be achieved with sufficient torsional rigidity for all used for the soles of the materials.

In a preferred embodiment, the thickness of the rear part of the sole is gradually increasing, from planovalgus of the area to the rear of the sole at least in the backward direction, starting from the bend planovalgus plot.

The longitudinal length of the section of the front part with a significantly reduced thickness may range from 5 to 15 cm, more precisely from 5 to 10 cm than guaranteed the required parameters of flexibility.

In a preferred embodiment, the front part planovalgus plot forms a bending area, which is formed at least one, and preferably from 3 to 6, smooth transverse bands, which are arranged with longitudinal intervals along the soles of parallel transverse grooves in the layer of the tread. Thus, the bending elasticity is not reduced.

The area of the curve of the front portion may include at least one, and preferably two, smooth longitudinal strips spaced from each other along the sole in the transverse direction and arranged in parallel longitudinal grooves, preferably is, longitudinal guide grooves made in the layer of protector, which also contributes to the bending of the sole.

According to another preferred variant implementation, the longitudinal and(or) lateral grooves, at least in the front part of the sole, formed mainly only in the layer of the tread, which may be made of a softer material than the material of the front and rear parts. Therefore, the material of the front part does not have any grooves, which could affect the flexibility.

This solution is also used in an additional embodiment, in which the bottom of at least part of the longitudinal and(or) the transverse grooves is limited to the front part and, if required, and also the rear part of the sole, made of a relatively rigid material. In another embodiment, the depth of the longitudinal(s) of the groove(s) approximately corresponds to the depth of the transverse grooves, which are preferably it(them) intersect.

In yet another embodiment, the transverse grooves, at least in the front, a bow-like curved back (on the bottom), increases the stability of the soles, especially torsional rigidity, and flexibility remains unchanged.

In a preferred embodiment, a smooth longitudinal and(or) cross-band limit at least part of the recess formed on top the th of the front part, besides, these pits appear from the bottom of the front and serve as a bearing lug formed in the layer of the tread. Thus, durable lug can be formed when molding the layer of protector using as the basis of the recesses forming the corresponding protrusions from the bottom.

In a more preferred embodiment, the height of the lugs is enlarged in the direction of movement so as to accommodate the lugs to the inclination of the front part at least in the area planovalgus plot. In this embodiment, is a flat bottom contact surface of the Shoe even when the inclination of the front part that contributes to sustainable connection of the Shoe, such as Shoe for cross-country skiing, ski bindings.

The sole can be made of plastic material with a modulus of elasticity in the range of from 200 MPa to 250 HPa, more preferably from 350 MPa to 200 HPa, and the thickness of the front part in a percentage greater at relatively higher elasticity than at relatively lower elasticity. This means that the higher the stiffness of the material of the sole, the less should be the thickness of the main soles at least in the area planovalgus plot.

The layer of the tread is attached to the bottom side of its bottom whether what about welding, either by molding or gluing.

In yet another private option on the front end of the sole is made of the receiving recess, the open side of the bottom, which houses at least one transverse axis for the swivel ski mount. This receiving recess on the sides preferably limited to two walls in the base or a layer of tread softer material. In accordance with one of the options in the edges of the sides of the recesses on the front end of the sole as its integral part for installation of the transverse axis and the connection has been anchoring elements, preferably metal. These anchoring elements are particularly necessary in the case when the transverse axis must be secured in a relatively soft layer of protector. To install the transverse axis, of course, also possible in the normal way to surround the recess on the front end of the sole two side walls (ribs)that make up one whole, with outer soles and are made of the same hard material as the whole sole.

The rear part of the foot, especially the heel, in the preferred embodiment, is of conventional construction, that is, in its upper part there are recesses to reduce material consumption and weight.

The present invention also offers a Shoe for cross-country skiing or for atania style Telemark, with the sole on one of the options above, directly attached on top of the Shoe in the form of the outer layer.

The present invention is described in more detail on the example of the preferred options with reference to the accompanying drawings, on which:

figure 1 shows the bottom view in perspective of the proposed soles;

figure 2 presents a view in plan on an enlarged scale of the sole shown in Fig 1;

figure 3 shows in reduced scale a longitudinal section of the sole shown in figures 1 and 2, along the line III-III in figure 2; and

4 shows a top view in perspective of a sole with 1.

Figures 1 and 2 in the bottom view shows the sole 10 or working surface of the sole of the ski boot for cross-country skiing. The sole 10 comprises rear (heel) part 11, on which the heel 13, and the front (toe) portion 12 slightly dished form, taimela the form of a flat bowl, and the sole 10 is made of a relatively rigid material, preferably plastic, and from the bottom (bottom) in the area of the front portion 12 and rear portion 11 has a layer (overlay) 14 tread from a relatively soft, preferably rubber-like, material. The layer 14 of the protector has a lug 14a to facilitate walking on snow. The layer 14 of the tread, in particular its lugs 14a, together with the United is it the parts 11 and 12 of the sole define a given overall thickness of the sole, or the thickness "h", shown in figure 3 so-called planovalgus section "M" of the bend. The thickness h may be different for different lug 14a.

Figure 3 shows that the thickness d of the front portion 12 in the area planovalgus plot M significantly reduced compared with the thickness of the remaining portion of the sole, so that the maximum Flexural elasticity of the sole 10 is achieved in the field planovalgus plot M, near the axis, located mainly across the longitudinal direction of the sole 10 in the field planovalgus section M. In particular, the reduction of the thickness d of the front portion 12 in the area planovalgus plot M as compared with the thickness in region 30 adjacent to planovalgus plot M and passing in the direction of the rear part of the sole 10, creates a configuration of the sole 10, with a very flexible front part 12 in the area planovalgus plot M and rigid or inflexible rear part 11, which tells the sole 10 high lateral stability. High flexibility of the sole 10 in the field planovalgus section M provides high boot features from the point of view of cross-country skiing, and the sole 10, in addition, gives good support for your feet.

The optimal ratio between the thicknesses d, d' may vary and depends on the specific material selected for the hard layer (uniform the layer for the front 12 and rear parts 11). Good results are obtained, if the thickness d of the front portion 12 in the area planovalgus plot M is from 1 to 4 mm, in particular from 2 to 3 mm. Thickness d' of the rear part 11 between the heel 13, located at the end of the rear part 11, and planovalgus area M may be from 2 to 8 mm, in particular from 3 to 6 mm. Thickness d of the front portion 12 of the sole 10 corresponds to a maximum of about 50%, in particular, as shown here, 25-30% of the total thickness h of the hard and soft material. The thickness of the soft material, and thus the thickness of the layer 14 of the tread in the area of the lugs 14a, may be from 3 to 7 mm, in particular from 4 to 6 mm, the Longitudinal length of the front portion 12, having a smaller thickness d is from 5 to 15 cm, in particular from 5 to 10 cm, which ensures sufficient band width of the front part 12 having the desired characteristics of the bend.

It is clear that there can be selected any other values of the thicknesses d, d' or longitudinal length as the upper or lower bound over a bounded interval, which achieves the best results, depending, for example, from the geometrical factors such as the shape of the sole or material properties, such as density of the selected material.

As clearly seen in figure 4, the front portion 12 in the area planovalgus plot M forms the ONU 25 bend, which is defined by four smooth cross strips 22, spaced at intervals along the sole 10. In addition, these transverse strips 22 parallel transverse grooves 16 in the layer 14 of the protector, as shown in Fig.1-3. It should be clear that the transverse strip 22 refer to the front part 12 and, thus, have the same thickness d as the front part 12. Area 25 of the bending of the front portion 12 also contains two smooth longitudinal strips 23, which are spaced transversely of the sole 10 and parallel to the two longitudinal guide grooves 15 formed in the layer 14 of the protector (Fig.1-3). These guide grooves 15 consistent with ski mount with the appropriate profile for the desired orientation of the ski boot. Also it should be clear, longitudinal strips 23 refer to the front part 12 and, thus, have the same thickness d, and the front part 12.

The bottom of at least the longitudinal guide grooves 15 in the anterior portion 12 of the sole is formed of a relatively hard material of the sole 10 and, hence, the longitudinal strips 23, while the bottom of the transverse groove 16 is formed of a thin layer of flexible or relatively soft material layer 14 of the protector, which does not affect the flexibility of the rigid front part 12, in particular on the flexibility of the transverse strips 22 of the front part 12. It follows that these grooves 15 16 formed, essentially, only within a softer layer 14 of the protector. This configuration, together with parallel transverse strips 22 of the transverse grooves 16, further enhances the flexibility of the front portion 12 in the area planovalgus plot M and, thereby, the flexibility of the zone 25 of the bend, to the extent that the layer 14 of the protector does not reduce flexibility, which is determined mainly by the reduced thickness d and the properties of the material of the front part 12.

In a preferred embodiment, the longitudinal and transverse grooves 15, 16 are molded so that they have approximately the same depth. The transverse grooves 16 in the front portion 12 and back portion 11 bent back.

As shown in figure 4, a smooth longitudinal and transverse strips 22, 23 intersect each other and thus define the boundaries of the several recesses 21 formed with the upper side of the front part 12. The recesses 21, which are located closer to the edge of the sole 10, partially limited by the strips 22, 23 and the surrounding material of the front part 12, which has essentially the same thickness d as the strips 22, 23. These grooves 21 form corresponding protrusions from the bottom of the front part 12, which serve as the basis and support for the lug 14a formed in the layer 14 of the tread (see figure 1, 2). The lugs 14a may be of any suitable material, and is housego virtually any suitable rigidity. In a preferred embodiment, the lugs 14a (and, hence, the layer 14 of the protector) is made of softer material than the hard material of the front and rear parts 11, 12 of the sole 10.

As clearly seen in figures 1 and 2, the lugs 14a are arranged in three longitudinal and six transverse rows in front of 12, and in three transverse rows at the back part 11, thus forming two longitudinal guide grooves 15 and several transverse grooves 16 on the bottom surface of the sole 10.

Figure 1 also shows that the height of the lugs 14a in the front part 12 is increased in the direction of motion so that the lugs 14 adapted to tilt the front portion 12 at least in the area planovalgus plot M the Lower surface of the lug 14a both the front and rear parts 11 and 12 are co-planar and form a flat bearing surface.

The transition from the front portion 12 in the area planovalgus plot M adjacent to the rear part 11, i.e. from the area with a reduced thickness d of the area with increased thickness d', occurs gradually, as shown in figure 3. This means that the thickness continuously increases, since the reduced thickness d of the front portion 12 to a maximum thickness d' of the rear part 11, in particular in front of the heel 13. Figure 3 also shows that the thickness "d" of the front portion 12 of the sole, SOS is oasa from a rigid material, continuously increases starting from planovalgus area "M", both backward and forward. Thus, planovalgus plot of the curve "M" is determined by appropriate choice of thickness d, d' of the sole 10.

On the front end of the sole 10 is made of extra recess 17, the open side of the bottom mounted inside the transverse axis 18 to swivel with ski mount. On the sides of the recess 17 is limited to two edges of the rigid material of the sole. In another embodiment, the recess may be restricted by the layer 14 of the protector. In the latter case, the side wall bounding the recess 17, it is advisable to seal the metal anchoring elements connected to the transverse axis 18.

The sole is made of plastic having a modulus of elasticity according to the above. It may be manufactured by the conventional methods by injection molding. The layer 14 of the tread of a soft material is attached to a more solid material from the bottom by welding, bonding or molding.

The heel 13 of the Shoe may be of conventional design, preferably such as shown in figure 3. In other words, from the top of the heel are grooves 20 to reduce material consumption and weight reduction.

You should also indicate that slightly dished shape of the front portion 12 of the sole 10 sposobem is no better stability, especially torsional rigidity of the sole 10. The depth of the transverse grooves 16 can be selected corresponding to the depth of the longitudinal guide grooves 15.

Within zone (M) of metatarsophalangeal joint of foot flexure, the sole maximum thickness is 50%, namely 30-35% from the overall thickness (h) of sole provided that preset overall sole thickness (h), which is comprised of hard and soft materials thicknesses, is invariable. In addition to cross grooves available in cover piece at least one guiding longitudinal groove is made. The bottom of part of cross and/or longitudinal grooves is made in the front part of the sole with relatively hard material.

EFFECT: technical result provides for footwear sole using according to invention and lies in applying simple technology of manufacture; so, sole has maximum bending elasticity and flexibility in metatarsophalangeal joint of foot flexure without loss of side stability chosen as structural basis.

FIELD: shoe industry.

SUBSTANCE: invention refers to shoe industry, particularly can be used for forced internal footwear ventilation due to atmospheric air injection through footwear toes. The atmospheric air is injected through horizontal elastic channeling arranged in the sole. The sole consists of at least three layers firmly interconnected. The centre contains soft and elastic material layer with horizontal elastic tubes. Elastic tubes or elastic channels are not interconnected. In walking the heel back interacts to the surface of the former, then sole and surface contact is shifted to the sole toes. Simultaneously the load is sequentially shifted from the heel to the sole toes. Under the gravity channels are deformed and blocked thus pushing the air through the channels from the heel to the footwear toes. Elastic tubes or elastic channels is small-diameter round or elliptic sectioned herewith the internal diameter does not exceed 1.5-2.0 mm. Pressure increase inside of the footwear causes air and water vapour exhaust through the natural cracks between a foot, internal surface of footwear top and toe material. It is repeated with each step, i.e. in walking horizontal channelling represents the pump which injects the atmospheric air to the footwear toe.

EFFECT: improved footwear comfort and hygienic properties.

FIELD: household goods and personal effects.

SUBSTANCE: atmospheric air is pumped through the system of horizontal elastic channels available in the shoe sole. They are placed in the cellular layer and do not interact with each other. While walking, the rear part of the leg heel interacts with the support surface of the front part. Then the sole contact with the surface moves to the toe part. At the same time, the load moves subsequently from heels to toe. The elastic channels of minor diameter of the cross section are deformed and blocked under the gravity effect. It helps to push air from hell to toe part of the show. The channel section diameter does not exceed 1.5-2.0 mm. Pressure is increased in the inner shoe volume resulting in air and water steam release through the natural slots between feet, inner surface of shoe top and toe material. The same action is repeated at each step, i.e. the system of elastic, horizontal channels is represented with a pump, which pumps atmospheric air into the toe part of the shoe.

EFFECT: more comfortable shoes, improved hygienic properties due to atmospheric air pumping through the toe shoe part.
