Description

Outsole {SOLE}

The present invention relates to shoes according to the preamble of claim 1, in particular for sports shoes / hiking shoes or ski boots / snowboard boots.

Outsoles of the type discussed herein are known in principle. It often has a cushioning contour that is used to relieve pressure on the foot, for example when hitting the ground in the case of running shoes. In the case of conventional shoes, this type of cushioning contour is arranged on the outer side, ie the side of the sole facing the ground. On the other hand, the inside of the sole, ie the side facing the foot, is flat and has no contours. This is intended to ensure comfortable bedding of the foot against the sole. As a result, cushioning against impact is achieved through the sole material. For this configuration, the sole can only be buffered within certain limits, particularly two-dimensionally, and not at selected points. Since the minimum material thickness of the rubber sole is generally 2 mm, the cushioning contour should have a material thickness significantly greater than 2 mm. Thus, the buffer contour increases the consumption of material associated with increasing weight.

Accordingly, it is an object of the present invention to provide a sole with low material consumption, with improved cushioning properties to relieve pressure.

The above object is achieved by a sole having the features of claim 1. The sole fits the manufacture of shoes, in particular sports shoes / hiking shoes or ski boots / snowboard boots, and has a cushioning contour located on the outside of the sole. The sole is distinguished in that the cushion contour extends over the inside of the sole.

The essential basic concept of the present invention is that flattening the interior of the sole is not necessary from a design point of view. On one hand, comfortable bedding of the foot is achieved when the cushioning contour extends over the inside of the sole, and on the other hand, the inside of the sole must be flat to adhere the sole to the top of the shoe by attaching the sole to the sole only at its edges. There is no need to do. In addition, another advantage of the cushioning contour extending over the interior of the sole is that it results in partial mechanical cushioning that can be achieved thereby. Thus, the buffering occurs exactly where the pressure occurs. Due to the cushioning contours formed on both sides of the sole, savings in terms of material and weight for the sole are calculated because no additional material is needed for the cushioning contours as the cushioning contours are fully integrated into the sole. . In addition, the buffer contours formed on both sides allow the formation of buffer elements that act independently of each other, thereby allowing pinpoint cushioning at the main pressure point under load.

It is particularly advantageous if the cushioning contours formed on both sides of the sole include at least one cushioning element. Preferably, the one or more cushioning elements have an elastically deformable hollow body that can be coupled to another cushioning element via lands / portions of material. By making the construction of the cushioning element in the form of a hollow body, in addition to improved cushioning properties, savings in terms of the material of the sole and hence weight are calculated. As a result, the outsole can be made more inexpensively.

Preferably, the one or more cushioning elements are elastically and fully integrated within the sole to form a two-dimensional spring element. As such, the cushioning element, designed as a hollow body, has corresponding connecting lands and holding lands, resulting in elastic bedding to the cushioning element within the sole. In this way, the cushioning element can perform a substantially free spring motion in both directions perpendicular to the sole plane.

In particular, it is preferred that the cushioning contour portion has a plurality of cushioning elements independent of each other, and that the plurality of cushioning elements include two or more main buffering elements and a plurality of secondary cushioning elements. In this case, one or more main cushioning elements may be disposed within the hind paw region, and one or more main cushioning elements may be disposed within the forefoot region of the sole. In addition, the main cushioning element can be surrounded by a secondary cushioning element in at least the regions. Moreover, a ground profile may be further formed in the hind paw region and / or the fore paw region. This ground contour can likewise form a plurality of pimple-like protrusions, at least adjacent to the main cushioning element and / or the secondary cushioning element within regions.

Preferably, the cushioning element is embossed in a three-dimensional, in particular pimple-like manner, and has a polygonal shape, in particular a hexagonal or circular cup shape or a truncated cone shape. In this way, a hollow body shape of the cushioning element can be produced. In order to stabilize the cushioning contour, a frame is provided that is coupled to the sole, in particular in one piece, so that it can completely surround the sole. Advantageously, the frame is joined to the sole in such a way that it is arranged at a distance from the running plane of the sole, in particular approximately 2 mm. In this way, the cushioning element can be moved in the spring direction independently of the frame and can create a corresponding cushioning. The sole is at least approximately 2 mm thick and preferably has a continuous material thickness of 2 mm, but it is possible to modify it for the actual height of the sole. This not only saves in terms of material, but also reduces the weight of the sole.

In order to achieve the above object, it is proposed that the shoes having the features of claim 14, in particular sports shoes / hiking shoes or ski boots / snowboard boots, have a sludge according to the invention according to one of claims 1-13.

The present invention will be described in detail below with reference to the drawings.

1 shows a cross-sectional view of a sole 10 known from the prior art. The sole 10 is intended to be coupled to the top 20. FIG. 1 makes it clear that the conventional sole 10 has a buffer contour 50 on its exterior 30, while its interior 70 is formed flat.

FIG. 2 shows a cross-sectional view of the sole 1 which is intended to be coupled to the top 2 and serves to manufacture any shoes, in particular sports shoes / hiking shoes or ski boots / snowboard boots. In principle, the sole design according to the invention can be used in the manufacture of any shoe. In this case, the present invention will be described with reference to a sole for snowboard boots.

Unlike conventional soles, the cushioning contour 5 extends not only over the exterior 3, but also over the interior 7 of the sole 1. Thus, the cushioning contour is actually designed to penetrate the sole. It is understood that the "outer" 3 of the sole in this case means the side of the sole in contact with the ground, while the interior 7 of the sole 1 forms the side facing the foot. As a result, the interior 7 is not designed to be flat, but according to the exterior 3, it has the structure of the buffer contour 5, ie the corresponding height and recess.

The outsole in the embodiment shown in FIG. 2 has a frame 9 for stabilizing the outsole, and may have a more flexible structure than a conventional outsole due to the cushioning contours formed on both sides. The frame 9 can be designed in one piece with the sole 1 or can be combined in different ways, in particular adhesively. The frame 9 is joined to the outer edge of the sole 1, thereby preferably completely surrounding the sole 1. The lower edge R of the frame 9 is arranged at a distance a from the running plane L of the sole 1. While the lower edge R is part of the frame 9 facing the ground, the running plane L is the plane of the sole that contacts the ground. The distance a between the lower edge R of the frame 9 and the running plane L can be changed according to the application. For example, it may be 2 mm or more. A sufficiently large distance (a) between the lower edge R and the running plane L means that the cushioning can take place unobstructed without a frame that hinders the cushioning motion of the cushioning contour.

FIG. 3 shows a side view of a shoe with a sole 1 according to the invention coupled to a frame 9. 4a shows a longitudinal sectional view of the shoe of FIG. 3 and a longitudinal sectional view of the sole 1 according to the invention.

Like FIG. 2, FIG. 4A makes it clear that the cushioning contour 5 extends over the outside 3 and over the inside 7 of the sole 1. Preferably, the buffer contour 5 extends over the main portion of the total area of the sole 1 and is integrally formed therein. It has one or more, preferably a plurality of cushioning elements 11 which are joined together via a region of material to at least form the main portion of the sole.

The cushioning element 11 and its operation are described with reference to FIG. 4B. In the present case, it is clear that the cushioning element 11 has a hollow body 13. For example, a hollow body shape, which may be just a pot-shape, is produced by the base 13a in this example, and is surrounded by an ascending flank 13b. The base 13a and the side portions 13b surround a cavity that opens toward the foot side. The material thickness of the base and side parts can be the same, and in particular can be 2 mm. In addition, equivalents are applied to the material forming the sole, land and other areas of the side.

The hollow body 13 or the cushioning element 11 is resiliently integrated in the sole 1 and, in this way, forms a two-dimensional spring element. As shown in Fig. 4B, to allow the spring movement in both directions 19 and 19 ', perpendicular to the sole plane E, the hollow body 13 of just shape is viewed as an inclined side section, cross section When coupled through a V-shaped or Z-shaped side portion, it is joined to a region of material that represents a connection to another cushioning element. Specific terms are provided, for example, the connecting land 15 and the holding land 17, and the connecting land that connects the hollow body to the holding land is coupled to or forms the area of the material.

The land and hollow body are elastically deformable and allow elastic bedding of the cushioning element in the sole 1. Accordingly, the cushioning element 11 can perform a spring motion in both directions 19 and 19 'substantially perpendicular to the sole plane E. Depending on the loading situation, the cushioning element 11 will undergo elastic deformation related to displacement in the direction of the arrow 19 or 19 '.

5 shows a top view of the outer 3 of the sole 1 according to the invention. The illustrated sole represents a preferred embodiment, the buffer contour of which has a plurality of cushioning elements. The buffer element consists of a main buffer element 21 and a secondary buffer element 23. One main cushioning element 21 in this case is disposed in the hind foot region 25 of the sole 1, and one main cushioning element 21 is disposed in the forefoot region 27 of the sole 1, thereby being selected Pressure relief and cushioning at the main loading zone at the point is achieved. The main cushioning element 21 is at least partially surrounded by a secondary cushioning element 23. Compared to the main cushioning element 21, the secondary cushioning element 23 has a substantially smaller area or smaller diameter, so that a larger number of secondary cushioning elements 23 than the main cushioning element 21 are outsoles. (1) can be covered. For example, approximately 100 or more secondary buffer elements 23 can be disposed between the two main buffer elements 21. As long as its construction and method of operation are of interest, the main and secondary buffer elements 21, 23 correspond to the buffer elements 11 shown in Figs. 4A and 4B.

In the embodiment according to Figure 5, the main or secondary cushioning element has a hexagonal shape. However, in principle, different polygonal shapes, circular shapes or alternatively (hemi) spherical shapes are conceivable. The cushioning element for producing the hollow body shape is embossed in a three-dimensional, in particular, pimple-like manner, and in particular, having a cup-shaped or truncated cone-shaped shape, the cushioning element opens toward the inside 7 of the sole It is crucial to form a hollow body that becomes and closes toward the outside of the sole.

In the embodiment of the sole 1 according to the invention shown in FIG. 5, the sole has a ground contour 29 in each case in both the hind leg region 25 and the forefoot region 27, thereby making the contour portion The contour as a pimple is exclusive to the grip and does not develop any cushioning action. Therefore, it should not be designed as a hollow body, but is advantageously formed by a solid body. The ground contour 29 is optional and can also be replaced by a cushioning element, so that the entire sole consists of a cushioning element and a material region disposed between them.

5 further clarifies that regions of the buffer elements of different sizes can be provided. Accordingly, all secondary cushioning elements 23 and main cushioning elements 21 never have the same dimensions. Rather, the secondary cushioning element can be designed to have different sizes. The main cushioning element should also not have the same shape and size. Also, the hexagonal shape of the cushioning element should not necessarily be applied for each cushioning element. In principle, mixing of differently formed, eg polygonal and circular cushioning elements is contemplated.

The secondary buffer element and the main buffer element are substantially different in their intended purpose and their buffer action. It is particularly advantageous if the main cushioning element with increased cushioning action is placed in a zone of high applied pressure, in particular in the hind and forefoot regions. However, in principle, any design can be spherical by means of a cushioning element. For example, the sole can be completely or partially penetrated by the cushioning elements, and the distribution of different types of cushioning elements can be individually tailored to any shoe and intended purpose.

The method of operation of the elastically bedded cushioning element 11 will be described later with reference to the longitudinal section of the sole 1 according to FIGS. 6-8. The longitudinal cross-sectional views shown in FIGS. 6-8 extend substantially through the main cushioning element 21 shown in FIG. 5 corresponding to the cushioning element 11 shown in FIGS. 4A or 4B. Fig. 6 shows the initial situation in which the sole 1 is shown in a non-loaded state.

Meanwhile, FIG. 7 shows a situation in which the cushioning element 11 develops a cushioning action toward the interior 7 of the sole 1. In this case, the elastically bent hollow body of the cushioning element is elastically displaced toward the inside of the sole 1. In this case, elastic deformation of the hollow body (especially the side part 13b and the side part (s) engaging the hollow body) into the surrounding sole material occurs.

On the other hand, in Fig. 8, the buffering action toward the outside of the cushioning element 11 is shown. Here, the hollow body 13 is displaced toward the outside 3 of the sole 1 in the direction of the arrow 19 '. In this case, the displacement of the cushioning element occurs in each case by deformation of the inclined connecting land 15.

As a result, pinpoint cushioning, particularly by stressed regions, can be caused by proper integration of the cushioning element in the sole 1. Sprung bedding of the spring motion of the cushioning element in both directions perpendicular to the sole plane and the resulting possibility allows partial mechanical cushioning. However, due to the construction of the cushioning element in the form of a hollow body, not only a particularly good cushioning is ensured by spring bedding of the cushioning element, but this construction of the cushioning element also saves in terms of material and weight of the sole. Accordingly, it is manufactured cheaper than a conventional sole. Consequently, the sole in the case of the surface covering configuration of the cushioning element can include a number of two-dimensional spring elements, which can develop different cushioning actions depending on the degree of embossing. These cushioning elements are arranged separately from each other over a region of material, so that in each case it is possible to achieve a buffering action independently of one another, ie substantially unaffected by one another. Accordingly, the sole can be individually configured according to the shoe and its corresponding application. However, not only can the construction and arrangement of the cushioning elements be altered, but the sole material is in principle not subject to any construction. For example, the sole can be made of rubber, or alternatively any other material suitable for making the sole.

Overall, the present invention is due to the contours on both sides and the cushioning elements (in the form of a hollow body) which can be produced, on the one hand saving in terms of material and weight, and on the other hand optimal pinpoint pressure relief and It provides a particularly advantageous sole that achieves cushioning.
