Description

  The present invention relates to shoes, and more particularly to shoes for playing sports.

  Such shoes can be used in fields such as sports or other walking, running on a flat or mountain, climbing, or skateboarding, ball games and the like.

  Some shoes are long and others are short. Also, some shoes are relatively soft and, conversely, are more rigid. However, whatever the overall appearance or activities performed, shoes must meet the expectations of users. In particular, first, the shoes must be able to easily extend their feet. This means that, for example, on a flat ground, walking or feeding must be free and regular. It is a problem to minimize the user's energy consumption for each movement of walking or running. Second, the shoe must be able to grip the ground sufficiently. This means that the shoe must be able to control the support, impact, or transmission of sensory information between the ground and the foot, and that it should not slip when inappropriate. means.

  In order to obtain easy walking and sufficient grip, the prior art has of course proposed a number of solutions.

  It is particularly known to produce shoes with small protrusions on the contact surface of the outsole with the ground. This structure provides sufficient foot freedom because the space between the protrusions allows the outsole to bend freely. In addition, the regular distribution of protrusions allows regular footing on the one hand and sufficient grip on a flat ground on the other hand. Such shoes are particularly suitable, for example, for walking or running in a stadium. However, in many situations, such shoes do not provide free and regular footing in all cases, even if they provide sufficient grip simultaneously. In fact, gripping is insufficient in certain situations. This is especially true on rough terrain with obstacles such as rocks that you encounter in mountains, and even in mountains and forests. In fact, in these situations, the contact surface between the sole and the ground is too weak to allow sufficient grip.

  There are other shoes that fit special situations.

  For example, according to US Pat. No. 4,130,947, the contact surface of the outsole has a series of lateral grooves. These grooves have a fairly large depth of a few millimeters. This sole enhances catch on brittle ground or snow. Grooves are provided to increase lateral stiffness and facilitate longitudinal flexibility. However, this shoe does not allow a completely free and regular footing of the foot. Indeed, the possibility of longitudinal bending of the outsole along the horizontal axis varies from place to place. The flexibility is large at the groove bottom, but decreases between the two grooves. This is because the sole thickness varies due to the groove. As a result, the hard zone and the soft zone can be alternately arranged in the lateral direction at the level of the outsole. This alternating zone interferes with the sole and thus with the foot and makes it irregular. Moreover, more force is required for the thick zone between the grooves to bend. In this sense, the energy yield associated with walking or running is lower. It must also be noted that the zone with a thin groove bottom is fatigued and damaged.

  No known shoe alone appears to combine the free and regular footing of the sole to the ground, sufficient grip on the even ground, and the ability to grip or catch on the uneven ground. In other words, the prior art shoes are not fully versatile or overly specialized as a consequence.

U.S. Pat. No. 4,130,947

  In this context, the present invention aims at improving the shoes according to the prior art. In particular, the object of the present invention is to combine a single shoe with free and regular footing of the sole to the ground, sufficient grip on the even ground, and sufficient grip or catch on the uneven ground. That is. This means that the present invention seeks to make shoes more versatile and more effective in all situations.

  Another object of the present invention is to apply this versatility broadly, ie for wet, moist or muddy land as well as foreseeable land such as dry land. You will see later that you are getting sex.

  A further object of the present invention is to provide some buffering capacity in the area of the outsole. The present invention seeks to optimize the behavior of the sole during the entire contact or at least a substantial portion of the ground depending on the activity being performed.

  Another object of the present invention is to improve the accuracy in the transmission of sensory information or impacts associated with walking or running.

  A further object of the present invention is to reduce the mass of the outsole as much as possible.

  To this end, the present invention includes an outsole and an upper, the outsole extending in the longitudinal direction from the rear end to the front end and in the width direction between the lateral edge and the medial edge. A shoe is proposed in which the outsole has a contact surface with the ground.

  In the shoe according to the present invention, the contact surface has a first contour portion, convex portions and concave portions are alternately arranged on the first contour portion, the contact surface has a second contour portion, The convex portions and the concave portions are alternately arranged on the two contour portions, and the convex portions and the concave portions of the first contour portion are alternately arranged with respect to the convex portions and the concave portions of the second contour portion. .

  The first contour portion includes a reference segment having one convex portion and one concave portion, and the second contour portion includes a reference segment having one convex portion and one concave portion. The convex portion of the reference segment is located beside the concave portion of the reference segment of the second contour portion, and the concave portion of the reference segment of the first contour portion is beside the convex portion of the reference segment of the second contour portion. It can also be said that it is located.

  In this structure, the convex portions and the concave portions are alternately arranged in the longitudinal direction of the contour portion, and the convex portions and the concave portions are alternately arranged in the lateral direction perpendicular to the longitudinal direction of the contour portion. The contour corresponds to a divided region or segment that divides the contact surface, and the contour may be linear or curved and may be oriented along the longitudinal or other direction of the shoe. You will see later that this can be done. Of course, the interleaving referred to above takes place in divided segments of the contact surface having convex and concave portions according to the invention. It will be appreciated later that the contact surface may comprise a plurality of split segments and may be configured entirely as such.

  Regardless of the outsole's footing direction, in the segmented segments, the protrusions alternately contact the level ground. This is because if the outsole is extended in the direction of the contour portion, the convex portion of the second contour portion will contact the ground later, or the other convex portion of the first contour portion will contact the ground later. If it tries, the convex part of a 1st outline part will contact with the ground, and the following is the same. Of course, this phenomenon occurs for all walking directions. As a result, the carrying of the outsole and thus the carrying of the foot is also regular and free. Similarly, since the transition from one convex to the other is regular in terms of support, this grip on the ground seems satisfactory. It can also be said that when the first is paid out with respect to the second, the continuity of the contact of the sole with the ground is observed.

  In the case of uneven ground that is somewhat covered with rocks in the mountains, the unevenness of the ground cooperates with the recesses of the shoe. In fact, these irregularities fit more or less in the recesses of the shoe. Since the shoe recess provides a larger contact area compared to the area of the opening defined between the protrusions, an increase in grip is observed in the region of the shoe recess. In addition, the shoe recess creates an obstruction connection between the ground irregularity and the outsole. As a result, the grip and / or catch on uneven ground is improved compared to that obtained with shoes according to the prior art. Also on muddy ground, the recesses of the shoe act as a large scour, from which mud is discharged very easily, which is likewise an improvement over the prior art.

  Finally, in the shoe according to the invention, the outsole is fed out regularly and freely against the even ground, fully gripping this ground and of course reversibly gripping even the uneven ground. Or get caught. After all, the shoe according to the invention is universal and grips the ground whether the ground is uneven or uneven.

  The shoe according to the invention allows a significant improvement in catch compared to prior art shoes.

  Other features and advantages of the present invention will be better understood using the following description with reference to the accompanying drawings, which are shown according to non-limiting embodiments, and how the invention can be implemented. .

FIG. 12 is a bottom view of the shoe according to FIG. 11.

  The first embodiment described below relates to shoes for walking or running on flat or undulating land, among others. However, the present invention is also applicable to other fields as described above.

  This first embodiment will be described below with reference to FIGS.

  As shown in FIGS. 1-3, a walking shoe is provided so that a user's foot | leg may be accommodated.

  As is generally known, the shoe 1 generally extends between the rear end 3 and the front end 4 along the longitudinal direction L, and with the outer edge 5 along the transverse direction W perpendicular to the longitudinal direction. An outsole 2 extending between the inner edge 6 is provided. The sole 2 includes a rear portion or a heel portion 7 and a front portion 8. According to the first embodiment of the sole, the sole 2 is integral in the direction in which the flange 7 and the front 8 extend. However, these parts 7 and 8 may be separated and spaced apart from each other.

  The shoe 1 includes an upper 9 disposed on the sole. As shown in the figure, the upper 9 includes a lower portion 10 provided so as to surround the foot except for the upper portion. However, the upper can also include an upper portion.

  The upper 9 includes in particular an outer quarter 12, an inner quarter 13, and a tongue 14. The tongue 14 connects the quarters 12 and 13 to each other to give the upper 9 its continuity. However, it is also possible not to use tongues. In this case, the quarters 12 and 13 may be separated or overlapped.

  Although not described in detail in the present specification, the tightening device is provided for reversibly tightening the upper 9. However, the shoe 1 may not have a tightening device.

  Whatever the structure of the upper, the outsole 2 has a contact surface 20 with the ground. The contact surface 20 is configured to have two or more contour portions 21, 22, 23, 24, 25 in total. The contour portion is a segment (segment) of the contact surface 20 whose length is larger than the width. It can be said that the contour is an elongated segment, but can have various shapes or various curved forms, as will be seen later. In particular, the contour portion may be configured by a straight line such as a rectangle, or may be a curved shape according to a shape such as capital C or S, for example.

  Although not limited, the contact surface 20 has at least one first contour portion 21 and a second contour portion 22. It will be seen later that the contact surface 20 may have a third contour 23, a fourth contour 24, a fifth contour 25, and even more contours.

  The first contour portion 21 includes, for example, convex portions (convex regions) 31, 32, 33, 34, 35, and 36 and concave portions (concave regions) 41 that continue alternately between the front end portion 4 and the rear end portion 3. , 42, 43, 44, 45. In all cases, the first contour portion 21 includes a reference segment 47 having a convex portion 32 and a concave portion 41. Of course, the convex portion 32 and the concave portion 41 of the reference segment 47 are adjacent to each other in the sense that one continues along the contour portion 21 to the other. This segment 47 is selected for ease of explanation because it is visible on the drawing.

  For the same purpose, the second contour portion 22 includes, for example, convex portions 51, 52, 53, 54, 55, 56, 57 and concave portions 61, 62 that continue alternately between the front end portion 4 and the rear end portion 3. , 63, 64, 65, 66 are included. In all cases, the second contour 22 includes a reference segment 67 having a convex portion 52 and a concave portion 62. Of course, the convex portion 52 and the concave portion 62 of the reference segment 67 are adjacent to each other in the sense that one continues along the contour portion 22 to the other. This segment was also selected for ease of explanation because it looks good on the drawing.

  According to the present invention, the second contour portion 22 is adjacent to the first contour portion 21, and the convex portion 32 of the reference segment 47 of the first contour portion 21 is the reference segment 67 of the second contour portion 22. The concave portion 41 of the reference segment 47 of the first contour portion 21 is positioned beside (next to) the convex portion 52 of the reference segment 67 of the second contour portion 22. ing.

  In the divided segment region of the contact surface 20 including the reference segments 47 and 67 of the first contour portion 21 and the second contour portion 22, convex portions and concave portions are alternately arranged in the longitudinal direction of the contour portions 21 and 22. Further, it is observed that convex portions and concave portions are alternately arranged in the direction perpendicular to the contour portions 21 and 22 and the longitudinal direction. In this segmented segment, the outsole 2 regularly and freely steps on the even ground, fully grips the ground, and reversibly grips or catches the uneven ground as well. In this segmented area, at least the shoe according to the invention is versatile.

  According to the described first embodiment, but not limited to, the contact surface 20 has a third contour 23. The contour portion 23 is, for example, an alternating arrangement of convex portions 71, 72, 73, 74, 75, 76 and concave portions 81, 82, 83, 84, 85 that continue alternately between the front end portion 4 and the rear end portion 3. including. The third contour portion 23 includes a reference segment 87 having a convex portion 72 and a concave portion 81. Naturally, the convex portion 72 and the concave portion 81 of the reference segment 87 are adjacent to each other along the contour portion 23. Again, this segment 87 was considered because it is well visible on the drawing.

  In the meaning of the present invention, the third contour portion 23 is adjacent to the second contour portion 22, and the convex portion 52 of the reference segment 67 of the second contour portion 22 is the reference segment 87 of the third contour portion 23. The concave portion 62 of the reference segment 67 of the second contour portion 22 is next to (next to) the convex portion 72 of the reference segment 87 of the third contour portion 23.

  In the divided segment region of the contact surface 20 including the reference segments 67 and 87 of the second contour portion 22 and the third contour portion 23, convex portions and concave portions are alternately arranged in the longitudinal direction of the contour portions 22 and 23. In addition, an alternating arrangement of convex portions and concave portions is observed in the lateral direction perpendicular to the longitudinal direction of the contour portions 22 and 23. Again, in this segmented segment, the outsole 2 regularly and freely steps on the even ground, fully grips this ground, and reversibly grips or even the uneven ground as well. Get caught. In this segmented segment area, the shoe is versatile.

  According to the first embodiment, the contact surface 20 includes exactly three contours 21, 22, 23, but the contours may be more or less. Accordingly, the contour portions 21, 22, and 23 extend over the entire contact surface 20. For example, the first contour portion 21 is located outside, the second contour portion 22 is located in the center, and the third contour portion 23 is located inside. This optimizes these capabilities in the sense that the ability to grip and step on the ground is demonstrated across the contact surface 20.

  Of course, in this optimization sense, the first contour 21 comprises several segments 47, the second contour 22 comprises several segments 67, and the third contour 23 comprises It includes several segments 87.

  As a non-limiting example, the following configuration is proposed in the first embodiment. The first contour portion 21 has five concave portions 41, 42, 43, 44, 45, the second contour portion 22 has six concave portions 61, 62, 63, 64, 65, 66, The third contour portion 23 has five concave portions 81, 82, 83, 84, 85. As a natural consequence, the first contour portion 21 has six convex portions 31, 32, 33, 34, 35, 36, and the second contour portion 22 has seven convex portions 51, 52, 53, 54, 55, 56, 57, and the third contour portion 23 has six convex portions 71, 72, 73, 74, 75, 76. It can be seen that the convex portions and the concave portions are alternately disposed along the longitudinal direction of each contour portion, and are also disposed alternately in the lateral direction perpendicular to the longitudinal direction of each contour portion. In fact, the convex portions and the concave portions are distributed in a so-called checkered pattern throughout the contact surface 20.

  It can be seen that the first contour portion 21, the second contour portion 22 and the third contour portion 23 are oriented along the length of the shoe 1, which is also the longitudinal direction L of the sole 2. This orientation provides stability to the sole 2 during the natural foot movement during walking or running in the forward direction.

  In addition, the concave portions 41 to 45 of the first contour portion 21 are aligned with the concave portions 81 to 85 of the third contour portion in the lateral direction, that is, along the lateral direction W of the outsole 2. As a necessary result, the convex portions 31 to 36 of the first contour portion 21 are aligned substantially laterally with the convex portions 71 to 76 of the third contour portion 23, respectively. As a result, high lateral stability occurs in the bearing against the ground, especially when the ground is flat. On the other hand, good lateral catch on the rough ground is also obtained. Actually, the respective concave portions of the central contour portion 22 are adjacent to the outer convex portion and the inner convex portion of the outer contour portion 21 and the inner contour portion 23, respectively. Accordingly, each of the recesses 61 to 66 of the central contour portion 22 is a cavity of the sole 2 that is simply recessed in the region of the contact surface 20. Therefore, if ground irregularities such as rock protrusions occupy space in the recesses of the central contour 22, lateral sliding of the outsole 2 is sometimes caused by the outer protrusions and sometimes It is obstructed by the inner convex part. In fact, each outer or inner protrusion functions as a stop in the lateral direction. For this reason, the timely loss of grip along the lateral direction is at least rare if not avoided, so the shoe 1 is particularly effective when running in the mountains.

  In terms of dimensions, for example, the width of the first contour portion 21 is 5 to 30% of the width of the outsole 2, and the width of the second contour portion 22 is 20 to 80% of the width of the outsole 2. And the width of the third contour portion 23 is configured to be 5 to 30% of the width of the outsole 2. As a result, the central contour 22 is usually selected wider than the outer contour 21 and the inner contour 23. The advantage that arises from this is that the lateral catch on the undulating land is optimized.

  In the first embodiment, the length of each of the first contour portion 21, the second contour portion 22, and the third contour portion 23 is 85-85 of the length of the outsole 2 in the longitudinal region. 100%. In this way, the process always proceeds in the direction of optimizing the aforementioned gripping and footing characteristics. Nevertheless, satisfactory results are observed when the length of each of the first contour portion 21, the second contour portion 22, and the third contour portion 23 is 20 to 100% of the length of the outsole 2. It was.

  Although not limited, the first contour portion 21 and the third contour portion 23 are extended from each other by the rear bridge 93 and the front bridge 94 in the region of the rear end portion 3 and the region of the front end portion 4, respectively. It is like that. After all, the outer contour 21 and the inner contour 23 are stretched together in the region of the rear end 3 and / or the region of the front end 4. Finally, the outer contour 21, the rear bridge 93, the inner contour 23 and the front bridge 94 form a peripheral belt of the contact surface 20. This belt helps to make the outsole 2 more regular. Of course, it is possible to provide a single bridge 93, 94 in the region of the rear end 3 or in the region of the front end 4 or no bridge.

  It can be seen that the width of the first contour portion 21 is constant, the width of the third contour portion 23 is constant, and the width of the second contour portion 22 is variable. Actually, the second contour portion 22, that is, the central contour portion, has the front portion 8 wider than the rear portion 7 as a whole. Thereby, lateral catch increases toward the front. The advantage arising therefrom is that the sole 2 is highly stable when it is strongly supported in the midfoot area of the foot, especially when the ground is undulating. Again, this shoe is very high performance when running in the mountains.

  Again, considering the performance, the outsole 2 is lightweight and has resistance to abrasion caused by contact with the ground. Actually, the outsole 2 includes a wear layer 95 for contacting the ground, and a connecting layer 96 that connects the wear layer 95 to the rest of the shoe 1. It is self-evident that the abrasion layer 95 defines the contact surface 20. The abrasion layer 95 is made of, for example, rubber or any equivalent material. According to the first embodiment, the coupling layer 96 is not limited, but is a buffer layer. This layer 96 thus comprises a low density rigid material, such as ethylene-vinyl acetate foam represented by the initial EVA, or any equivalent.

  Each of the layers 95, 96 extends along the entire outsole 2. This provides a gripping capability simultaneously with a buffering capability for the entire contact surface 20.

  Of course, the sole 2 may include more than one layer and / or additional elements.

  As can be understood from FIGS. 1-7 as a whole, according to the first embodiment, the outsole 2 includes an abrasion layer 95 with a thickness t that is normally constant. Thereby, manufacture becomes easy and it becomes possible to make the sole 2 lightest to the maximum.

  The expression normally constant means that the wear layer 95 has a constant thickness, despite small protrusions added to improve grip on wet ground. Actually, most of the convex portions 31 to 36, 51 to 57, and 71 to 76 have irregularities represented by reference numeral 97. For example, it is to be understood that these V-shaped irregularities are small protrusions having a thickness of 0.5 to 7 mm, and good results have been obtained with values of 1 to 3 mm.

  These irregularities (protrusions) 97 are particularly for cooperating with the ground with a smooth surface, so it is not necessary to provide them in the depressions. In other words, most of the recesses 41 to 45, 61 to 66, and 81 to 85 have a smooth surface. This makes sense as long as the recess is suitable for cooperating with bumpy land protrusions.

  Alternatively, it is observed that the protrusions 31-36, 51-57, 71-76 may have a surface that is mostly uniform, i.e., free of irregularities 97. In this case, the shoe 1 has a very high performance with respect to the dry ground, whether it is flat or undulated.

  According to the first embodiment, it is observed that the outsole 2 includes the abrasion layer 95 having a thickness t of 0.5 to 5 mm regardless of the unevenness (protrusion) 97, and a value of 1 to 3 mm. Please be aware that good results were obtained.

  As will be more clearly understood from FIGS. 4-7, the tops of the protrusions 32, 52, 53, 72 along the divided segments in the lateral (width) direction of the contact surface 20 are substantially in the same plane. . Furthermore, in general, the tops of all the convex portions are configured to make a printing pressure while contacting the level surface of the ground when the contact surface 20 travels. Therefore, of course, this allows the outsole 2 and regular foot travel.

  With particular reference to FIGS. 4 and 5, it is observed that the buffer layer 96 is continuous in the lateral direction, ie from the outer edge 5 to the inner edge 6. For the wear layer 95, this is divided. More specifically, each of the contour portions 21, 22, and 23 is provided with the wear layer 95 individually rather than integrally, and corresponds to the divided segments. This makes it possible to obtain the protruding contact surface 20 even when the wear layer 95 is initially adapted to a flat ground. However, as will be appreciated later, the entire wear layer 95 can be molded as an integral part.

  As can be seen from the entirety of FIGS. 1-7, and in particular from FIGS. 6 and 7, most of the recesses have a curved shape. For example, the 1st recessed part 41 of the 1st outline part 21 has the concave bottom part 100 and the convex walls 101 and 102, and the convex wall makes the bottom part 100 into the convex parts 31 and 32 of the same outline part. Link. This facilitates the manufacture of the sole 2 and also allows a good transition between the support for undulating land and the support for flat or level land.

  Another embodiment is shown below with reference to FIGS. For convenience, elements common to the first embodiment are denoted by the same reference numerals. Only the differences in nature are clearly shown.

  First, a second embodiment will be described with reference to FIGS. Indeed, as in FIGS. 4 and 5, two cross-sectional views are shown. Here, it can be seen that the abrasion layer 105 of the outsole 2 is continuous from the outer edge 5 to the inner edge 6. After all, the entire wear layer 105 is an integral part.

  A third embodiment is shown in FIG. Similar to FIG. 1, the outsole 2 of the shoe 1 includes a first contour portion 21, a second contour portion 22, and a third contour portion 23. Unique to this embodiment is that one or more of the recesses 62-66 are sectioned or divided. For example, the recesses 62-66 of the second contour 22 are essentially divided by a thin wall, such as denoted as 111, 112 for the second recess 62 of the second contour 22. Yes. These walls 111, 112 may be elastic elements for exerting an elastic recovery after the deformation of the sole 2, for example related to foot travel. With this arrangement, it is possible to accumulate energy related to foot travel and restore energy at the end of foot travel. The re-carriage of the shoe and thus the foot is improved.

  Next, a fourth embodiment is now illustrated in FIGS. It also has a first contour 21, a second contour 22, and a third contour 23, the contact surface 20 also has a fourth contour 24, The contour portion has an alternating arrangement of the convex portions 121 to 124 and the concave portions 131 to 133, the contact surface 20 further includes a fifth contour portion 25, and the fifth contour portion includes the convex portions 141 to 145 and The convex portions and the concave portions of a given contour portion are alternately arranged with respect to the convex portions and the concave portions of the adjacent contour portions. It can be seen that the contours 21 to 25 are adjacent to each other.

  Observe that the first contour portion 21, the second contour portion 22, the third contour portion 23, the fourth contour portion 24, and the fifth contour portion 25 are oriented along the longitudinal direction of the shoe. Is done. Here, the first contour portion is located outside, the second contour portion 22, the third contour portion 23, and the fourth contour portion 24 are located in the center, and the fifth contour portion 25 is located inside. positioned. Although it does not limit, the 1st outline part 21 has four recessed parts 161-164, the 2nd outline part 22 has three recessed parts 171-173, and the 3rd outline part 23 has four The fourth contour portion 24 has three concave portions 131 to 133, and the fifth contour portion 25 has four concave portions 151 to 154. Finally, the shoe 1 according to the fourth embodiment employs the same technical idea as the other embodiments. In this sense, the shoe is very versatile as explained above, but because of the small number of recesses per contour, the shoe 1 contains some more proportioned parts than undulating parts. Suitable for mixed courses.

  In all cases, the present invention is practiced from materials known to those skilled in the art by implementation techniques known to those skilled in the art.

  Of course, the present invention is not limited to the embodiments described above, but includes any equivalent that may fall within the scope of the appended claims.

  Specifically, the number of contour portions can be changed. Depending on the extent of the contour, the various recesses can have different dimensions. Similarly, the various protrusions may have different dimensions.

  For the recesses, they or some of them may not have all or only a part of the wear layer.
