Description

The The invention relates to a shoe, in particular a sports shoe, with a shoe upper and a sole, the sole one with the Shoe top firmly connected carrier or inner part and a with the carrier or inner part connected sole element.

Shoes This type are well known in the art. In order to and damping behavior of the shoe according to the desired It is still known, especially in the midsole damping elements integrate so that the sole in this particular characteristics be lent.

Out WO 03/092423 A1 is a damping element for one Shoe, especially for a sports shoe, known, which has a special construction. The damping element has a large number of individual elements arranged side by side, each one spring and a damping chamber after Forming a piston-cylinder system. In the form corresponding first and second elements are over a connecting portion connected to each other, wherein under load the sole the smaller trained element enters the larger, for this forms a recording room.

Of the Use of such damping elements in the sole has proven to be very beneficial. However, that is production technology to operate a considerable effort to the in particular by injection molding manufactured damping element to mount in the shoe or to integrate into this. Will that be damping element integrated into the midsole, a receiving space must first be introduced into this or this receiving space must be in the production of the sole getting produced. Then the damping element must be made and this finally be built into the midsole before this with the other Shoe components is connected.

Of the Invention is based on the object, a shoe, in particular to create a sports shoe, of the type mentioned above, itself characterized by a simpler method of preparation, but where in particular not on the advantageous property of the previously known damping element should be waived. It should be possible in particular, the spring and damping behavior to be influenced by the shoe.

The solution this object by the invention is characterized in that the sole element with the carrier or inner part connected by means of a positive connection is.

Prefers is doing a plug connection between two parts, namely between the carrier or Inner part and the sole element, thought by plugging together together can be whereby by positive engagement the transmission of usual forces during the Use of the shoe can be recorded.

The positive Connection between the carrier or inner part and the sole element may be detachably formed, whereby it becomes possible If necessary, remove the sole part and replace it with another one. The positive connection between the carrier or inner part and the sole element may for this purpose preferably a provided with at least one locking projection resiliently biased Clip closure have. Through such a clip closure can the sole part at the carrier or inner part latching be fixed, so that sufficient strength against burdens by usual using powers given is; However, the clip closure can also be solved again, to replace the sole part if necessary.

The positive Connection between the carrier or inner part and the sole element can also be formed insoluble alternatively be. It is especially thought that the carrier or Inner part and the sole element to the positive connection with each other are glued.

Especially it is preferably provided that the positive connection by at least one at the carrier or inner part or arranged on the sole element and from the Sole plane in the vertical direction (with the usual resting of the shoe on the floor) extending into a projection shape-congruent recess in the sole element or in the carrier or Interior part intervenes. It is particularly envisaged that the at least one projection on the carrier or inner part and the at least one recess on the sole element is arranged.

By This configuration makes it possible by Force application between carrier or inner part and sole element in the vertical direction these two To assemble parts, so that they are secured against unintentional disconnection. The assembly process The shoe is thereby considerably simplified.

The projection and the associated recess preferably have a polygonal, in particular a hexagonal, shape in a section perpendicular to the vertical direction; a circular design is possible. Preferred is a number of juxtaposed projections and recesses arranged on the support or inner part or on the sole element.

The Carrier- or inner part is advantageously plate-shaped, wherein the Top of the carrier or inner part is connected to the shoe upper and at least a projection from the bottom of the carrier or inner part down extends.

alternative For this purpose, it can also be provided that the carrier or inner part at least is partially formed as a lattice structure, wherein the top of the Carrier- or inner part is connected to the shoe upper and at least a projection from the bottom of the carrier or inner part down extends. By using a grid structure is a special lightweight construction possible.

It can be a number of form-fitting Connection between the carrier or inner part and the sole element only in a portion of the Sole can be arranged. It is especially thought that the form-fitting Connections along the edge region of the sole are arranged. As a result, with minimal installation effort sufficient attachment of the sole element on the carrier or inner part can be achieved.

The Sole element can at least over a part of the ground tread surface of the shoe as a damping element be formed, which has at least a first element, the essentially in a load direction in the unloaded state the damping element via a predetermined height extends and, as a hollow body formed, defines a receiving space, in which an associated second Element, smaller in cross-section than the first element at least partially penetrate, wherein the second element itself essentially in the loading direction in the unloaded state of the Damping element over a predetermined Height extends and is arranged coaxially with the first element. Such a damping element is already known as such and described above in WO 03/092423 A1.

there a number of juxtaposed first elements can be provided be, each interacting with a second element. The Shape of the first element may be in a section perpendicular to the vertical direction correspond to those of the projection or the recess. The height of the first Elements can be larger or be equal to the height the projection or the recess, whereby a defined investment of the sole element on the carrier or inner part can be created.

At least a part of the second elements may be a prism or cylinder shape have, wherein the prism or the cylinder at least partially is designed as a massive part. At the side facing away from the first element An outsole can be placed at the end of the second element. These can be formed by a number of individual sole parts, wherein each sole part is arranged on a second element.

The Both elements assigned to one another can be connected to one another via an elastic connecting section be connected, which only between the first element and the second element. In each case a first element and a second element may be used together with the connecting section and the carrier or inner part form a gas-tight chamber, what the spring and damping properties positively influence. The first element and the second element can in a section perpendicular to the loading direction one to another have corresponding shape. Furthermore, the first element and the second element in a section perpendicular to the loading direction have a polygonal, in particular hexagonal, shape.

Several first elements can be connected in their lateral area or it can be their lateral boundary walls each formed from a common section. The first Element, the connecting portion and the second element are preferred one piece educated. Then it is advantageously provided that the first element, the connecting portion and the second element by a common injection molding are made.

The first and / or second elements preferably have at least partially in the unloaded state of the damping element different heights on. The connecting portion can in the unloaded state of the damping element run flat or curved in a plane perpendicular to the loading direction. With the latter embodiment, the entry of the "piston" is favored in the "cylinder" under load.

In order to this with a return effect done with pressure relief of the damping element can, is the lower axial end portion of the first element and the upper axial end portion of the second member via the connecting portion connected with each other. It is at the connecting section - as well at the first and second element - around a part of elastic plastic material, such that upon application of a loading force on the damping element in the loading direction a deformation takes place. The second element occurs like a piston in the receiving space of the first element one.

The Forming a gas tight chamber within the first and second Elements advantageously has the consequence that after pressure relief of the damping element the initial state is quickly reached again

Individual "piston-cylinder elements" are forming a damping element with larger areal extent arranged side by side. While the first elements acting as "cylinders" be connected to each other, are the second elements, the "piston", preferably freely side by side.

The with the damping element provided or formed by this sole element can under load absorb the sole in the direction of load energy and discharge them leave the sole again.

The Elements are preferably made of plastic, in particular of thermoplastic material. It is especially preferred on polyethylene, polypropylene, polybutane, Polyamide, polyurethane or a mixture of at least two of these plastics thought. The plastic can be translucent or transparent. Even the outsole can of plastic, preferably of polyethylene, polypropylene, polybutane, Polyamide, polyurethane or a mixture of at least two of these plastics, or made of rubber, the material is not translucent or not transparent.

Of the Material of the first element, the second element and the connecting portion and / or the geometric dimensions of these parts and / or the volume fraction of the solidly formed part for determining the spring and / or damping properties of the damping element selected become.

With Advantage is the first element in the unloaded state the midsole with its axial extent substantially outside the axial extent of the second element. This is to understand that the piston-like second element in the unloaded state of Midsole axially outside of the cylinder-like first element is arranged. Only when loaded of the damping element in the loading direction then enters the "piston" in the "cylinder".

With the proposal of the invention will it be possible from known welding or sticking the components of the shoe off and a simpler way for the Assembly of the shoe components to use.

Especially It is also advantageous that an interchangeability of the sole element possible so that the shoe when needed to desired (spring and damping) properties can be adjusted.

In the drawing are embodiment of Invention shown. Show it:

1 schematically a shoe, viewed from the side,

2 the magnification "Z" according to 1 .

3 the section AB according to 2 .

4 the bottom of the support or inner part of the shoe in perspective view and

5 a part of a formed as a grid structure carrier or inner part of the shoe in a perspective view.

In 1 is a shoe, namely a sports shoe, shown only very schematically. The shoe has a shoe upper in a known manner 1 that with a sole 2 connected is.

The sole 2 is designed to be in the front sole area 14 extends over a certain areal extent. In the backsole area 15 It also expands over a defined areal extent.

The construction of the sole 2 goes into more detail 2 out. The sole 2 consists of two (soles) parts, namely a carrier or inner part 3 and a sole element 4 , In the carrier or inner part 3 It can be an insole, an insole, a Stohlelsohle or directly to stem material that the connection between the shoe upper 1 and the sole part 4 forms. A preferred embodiment provides that the carrier or inner part 3 manufactured as a plastic injection-molded part (preferably made of EVA) and cup-shaped.

The carrier or inner part 3 is with the shoe upper 1 connected. The connection can be made, for example, by an injection molding process by the carrier or inner part 3 forming plastic material to the existing example of textile upper part 1 is injected. The same is true for gluing shoe uppers 1 and carrier and inner part 3 possible.

The sole element 4 consists of a plurality of damping elements, which are constructed in the manner of a piston-cylinder system. Am from the carrier or inner part 3 distant end of the sole part 4 is an outsole 12 arranged, the ent of one of the number of damping elements corresponding number of outsole segments.

It should be noted that it is not necessary that the entire sole be constructed as explained. For example, only the front sole area 14 be designed as described, while the rear sole area 15 can be formed in a previously known manner.

In the embodiments, the outsole 12 formed segmented, wherein the damping element forms only a midsole. However, it can also be provided that the outsole 12 is attached as a large-scale element at the axial end of the piston-cylinder systems. Likewise, the sketched damping element can be integrated in a classic midsole, as it is known in the art as such (see, for example, the EP 0 387 505 A1 ).

The exact structure of the sole 2 goes for the embodiment with segmented outsole 12 from the synopsis of 2 and 3 out.

The individual damping elements that form the midsole are in the embodiment - in loading direction R of the sole 2 considered - formed with a hexagonal basic shape in the manner of a honeycomb pattern (s. 2 ).

Each damping element has a first element 9 which extends over a defined height H and a receiving space 10 forms. Via a web-shaped connection section 13 is that of the carrier or inner part 3 opposite end of the first element 9 with a second element 11 connected, the one to the shape of the first element 9 has corresponding shape - viewed in the direction R -, ie, the second elements 11 have a hexagonal shape in the embodiment. The second element 11 extends over a height h, which does not have to be equal to the height H.

How out 3 it can be seen, is an essential aspect of the invention that between the carrier or inner part 3 and the sole element 4 a positive connection 5 is provided. In the embodiment according to 3 becomes the positive connection 5 by hexagonal (honeycomb) trained, web-like projections 7 formed, arising from the sole plane 6 extend vertically outwards in the vertical direction V over a certain height L. The first element 9 , which - as explained - are also hexagonal in the embodiment, make a congruent shape to the projections 7 ie, they form a recess 8th leading to the shape of the projections 7 corresponds. In this case, a small oversize is provided, so that when compressed in the vertical direction V of the carrier or inner part 3 on the one hand and sole element 4 on the other hand, the projections 7 into the recess 8th insert and by slight press fit between projection 7 and recess 8th ensure a firm grip.

How out 3 it can be seen, the dimensions - the width of the first element 9 and the width of the second element 11 - chosen so that the second element 11 when loading the damping element in the loading direction R in the receiving space 10 can enter through the first element 9 is formed. The first element 9 and the second element 11 Consequently, work in the manner of a telescopic damper, wherein the first element 9 acts as a "cylinder" into which the second element 11 can occur in the manner of a "piston".

At the of the carrier or inner part 3 opposite end of the second element 11 is an outsole segment 12 attached, z. B. glued or molded directly, which consists for example of abrasion-resistant plastic material. In the direction of R has also considered the outsole segment 12 a shape similar to that of the second element 11 corresponds, which does not necessarily have to be the case.

Will on the outsole segment 12 abandoned a force in the direction of R, as is done when the shoe hits the ground, deformed in particular the elastic connecting portion 13 which is the exclusive connection between the first and the second element 9 . 11 represents, so that, as explained, the second element 11 in the manner of a piston in the receiving space 10 of the first element 9 entry.

In order to positively influence the jounce behavior, that of the first element 9 , the connecting section 13 and second element 11 enclosed space to be formed gas-tight. For this purpose, the carrier or inner part must 3 with its projections 7 in cooperation with the recesses 8th also be formed gas-tight.

This is certainly ensured when the sole element 4 with the carrier or inner part 3 is glued, in which case, of course, a change of the sole element 4 is no longer possible.

If gas-tightness is not desired, for example, the carrier or inner part 3 be provided with recesses.

It can also be provided that the sole element 4 with the carrier or inner part 3 by snap connection or by Clipverbindun interacts. This is then - which is not shown - an elastically biased undercut in the carrier or inner part 3 or in the sole element 4 provided, which cooperates with a corresponding hook element in the other part.

In 4 is the carrier or inner part 3 shown in perspective view, with a view of the underside of the part, with the sole element 4 interacts. To recognize is a number of web-like projections 7 that is normal from the sole plane 6 rise.

The shape and size of the projections 7 is adapted to the respective needs, with a hexagonal shape preferred, but by no means mandatory. It can also be provided that only in the edge region of the plate-shaped base part of the carrier or inner part 3 projections 7 are provided, in the interior of the plate, however, only a projection-free contact surface for the sole element 4 is trained.

Out 5 shows that the carrier or inner part 3 - in contrast to 4 - Can also be formed only as a grid structure. In this case, the carrier or inner part 3 through a mesh of grid elements 16 formed, which may have any shape, which is from the grid structure then the web-shaped projections 7 can raise. The grille is made with a suitable process with the shoe upper 1 connected.

The embodiments provide that a sole element 4 It is also possible, however, for the carrier or inner part to be used in the same way as the "piston-cylinder damping elements" explained 3 simple honeycomb cells or round cells are attached, which are fixed by the positive connection according to the invention. The degree of coverage of the sole area is arbitrary.
