Abstract

An insert, which can be connected to a sole of a ski boot, the insert comprising: an anchoring structure (1) and a receiving structure (2), wherein the anchoring structure (1) and the receiving structure (2) are integrally formed from a semifinished product or the anchoring structure ( 1) and the receiving structure (2) produced separately and joined together, preferably joined materially.

Description

The invention relates to an insert that can be connected to a sole of a ski or snowboard shoe, for example, introduced into the sole, so that the shoe is prepared to be used together, for example, with a pin binding. The insert includes a receiving structure and an anchoring structure integrally formed or integral with the receiving structure and anchoring the receiving structure firmly in the brine. Fixed here means that the receiving structure can not move relative to the sole or the shoe even at high loads.

In the development of sports equipment, in addition to the design, which is the first purchase incentive, weight and price in the focus. Both should be as low as possible without affecting the safety of the sports equipment. In Gleitbrettbindungen example, weight can be saved by the fact that the housing for the toe and / or the buttocks are formed as a skeleton structure. The choice of material can affect both price and weight, often with the lighter material being more expensive than the heavier, which often results in a higher weight on the weight side.

Especially in Gleitbrettsport weight and price manipulation can be made not only on the sports equipment itself, but also on the secondary sports equipment, which means the shoe, which must be a special shoe and is usually used only in connection with the sliding board, you can see from short walking distances. That is, in Gleitbrettsport it makes sense to consider both the sliding board itself, as well as the matching shoe in terms of weight and price optimization, as well as possible price or weight reductions in the sliding board shoe contribute to a price or weight reduction of the overall system. Price reductions can be achieved, for example, by using alternative materials and / or manufacturing processes. For example, for shoes that are prepared to be used in a pin binding, the pin mounts are made of metal in a die casting process. The tools used for this purpose are a significant cost factor, which essentially determines the price of the pin recordings and thus not negligibly affects the price of the system "shoe".

It is therefore an object of the invention to provide parts for a sliding board or ski boot, which are at least cheaper to produce, than comparable parts already in the trade. It is another object to provide a low-cost shoe.

These objects are achieved by the subject matter of claim 1 and the shoe according to claim 11. Further embodiments of the invention are the subject of the dependent claims. These can be combined with each other in a technologically meaningful way, even across all categories of claims. The description, in particular in conjunction with the drawings, additionally characterizes and specifies the invention.

One aspect of the invention relates to an insert that can be connected to a sole of a ski boot. The ski boot is a gliding board shoe, but can also be a shoe that can be used with a snowboard. In the application, a ski boot is used throughout to facilitate the reading of the application. However, this does not mean that the invention is limited to ski boots in the narrower sense, but relates to each sliding board shoe, where appropriate.

The insert includes an anchoring structure and a receiving structure. The insert with the anchoring structure and the receiving structure may be formed integrally, that is, as a single piece, preferably formed from a single material. Alternatively, the anchoring structure and the receiving structure may be separately manufactured parts that are joined together to form the insert together.

The one-piece insert may in particular be a flow press or a roll profile whose free end is shaped as a receiving structure, for example by embossing, drilling, grinding and / or milling. On the body of the insert outside the receiving structure, the anchoring structure may be formed, for example, also by embossing, milling or grinding. The body of the insert may be formed as a solid cylinder, with a round, oval, teardrop-shaped or any cross-section. The free ends may have the same cross-section as the body of the insert, or a different cross section. For example, the receiving structure can be widened relative to the body, that is, have a cross section with a larger diameter in at least one direction.

The anchoring structure serves to anchor the insert firmly in the sole. In this case, the anchoring structure anchors the insert in the sole in such a way that the insert can not essentially move relative to the sole, even under extreme loads, as can occur during sliding board running.

The receiving structure may have a functional surface which may form a receptacle, for example for an engaging member of a binding. The Functional surface may form a free end of the receiving structure or the insert or may be formed at a free end of the receiving structure or the insert. The functional surface can still be accessible even if the insert is integrated in the sole, or the shoe.

The shoe may be a shoe made in one piece and not having a separate sole. In this case, the insert is integrated in the shoe, or in the part of the shoe which forms the tread surface. The sole may be a compact sole, for example, or a sole made up of several separable parts. The latter may, for example, have interchangeable areas at the front and / or rear end in order to be able to adapt the shoe to different bindings, that is to say toe holders or toe pieces and / or heel holders or buttocks.

In this special case, the insert is preferably located in the respective exchangeable area of the sole.

Alone the manufacture of the insert from a single part, or from two separate parts which are joined together preferably cohesively, can already be beneficial to the cost, in particular the tooling costs. In this case, no joining process must be provided and also the tool costs can advantageously be cheaper.

A cost advantage can also be obtained if the insert is formed of the two separate parts and the connecting structure is made of a first material and the receiving structure is made of a material different or different from the first material.

Thus, in the two-part insert, the anchoring structure, which is completely encapsulated with sole material when bonded to the sole or ski boot, may be formed of, for example, a simple structural steel. If the anchoring structure is embedded in the sole, it will not, or at least only to a very limited extent, come into contact with oxygen and moisture, so that oxidation of the structural steel does not take place or if only very slowly. That is, the strength of the anchoring structure will not diminish over an average life of a shoe, even if it is made of a material that can corrode in conjunction with oxygen. Post-treatments, such as hardening or anodizing, are also not necessary, since the anchoring structure essentially serves exclusively to anchor the receiving structure firmly in the sole.

It is advantageous that the connection structure can be quickly and inexpensively adapted to different shoe types, special requests of the manufacturer can be implemented as a rule quickly and inexpensively. The connection structure can also be easily adapted to existing tool holders of the shoe manufacturer usually, for example, with regard to the insertion devices and the attachment points.

By contrast, the receiving structure of the insert of two joined parts can be made of a high-strength stainless steel, since at least the functional surface is constantly exposed to the environment, ie the moisture and possibly the snow added salts, and the receiving structure directly on the shoe during a Gleitbrettbenutzung occurring forces must record. The receiving structure may additionally be refined, for example hardened, anodized, coated or otherwise treated. In this case, as already described above, the receiving structure may be a forged part and / or may be formed from a roll profile or a flow-molded part. The material for the receiving structure may be, for example, stainless steel, preferably with a high strength.

The material from which the receiving structure is formed may differ from the material of the anchoring structure, in particular with regard to hardness, strength, ductility and strength, as well as the price.

For joining, the anchoring structure and the receiving structure may have joining surfaces which lie flat against one another when the insert is joined by welding, for example. In this case, the receiving structure in the region of the joining surface have a greater material thickness than the anchoring structure, or vice versa. The anchoring structure and the receiving structure can be connected to one another, for example, by means of a fillet weld.

Alternatively, the receiving structure can encompass and / or overlap the anchoring structure in regions, or vice versa. That is, the receiving structure and / or the anchoring structure may, for example, have a groove or an opening into which the other of the structures can engage with a correspondingly formed engagement element.

The two interconnected structures can then be joined together, for example, by fillet welding, resistance welding or spot welding. In fillet weld or spot welding, a laser can be used to locally liquefy the metal to make the joint.

The anchoring structure and / or the receiving structure can be formed, for example, as a roll profile, extruded part, stamped part, forged part, sheet metal plate or laser cutting part. In particular, forged parts and extruded parts have a high dimensional accuracy and high repeatability, which is particularly advantageous for the production of the receiving structure. The surface quality of the tool falling part is high.

The functional surface may be formed as a separate inlay, which can be connected captively to the receiving structure. In preferred embodiments, the functional surface can then be replaced in order to adapt the insert to different engagement elements, to give the insert an additional design feature by changing the color of the functional surface and / or to be able to replace the functional surface when worn.

The insert or the receiving structure may each have a functional surface at two opposite free ends. In this case, the insert or the receiving structure may pass through the sole in a connecting region transverse to an axial direction of the sole. The two functional surfaces can be identically shaped or mirrored. The functional surfaces have mirrored positions on the sole relative to a sole tip center or sole end. That is, in other words, a distance of the functional surfaces to, for example, the sole tip center is identical, as is a distance of the functional surface to the sole bottom. The two-sided functional surfaces may in particular be, for example, conical receptacles in which pins of a front jaw of a pin binding engage can.

In particular, in the case of the insert, which is formed from a separately manufactured receiving and anchoring structure, the receiving structure can consist of two receiving substructures which are individually joined to the anchoring structure and each have a functional surface. These two receiving part structures can be connected to the anchoring structure in different positions, so that the insert can easily be adapted to soles or shoes of different widths in the area of the insert, since it is not the geometry of the anchoring structure of the receiving structure that has to be changed, but only the Positioning of the receiving part structures on the anchoring structure is varied.

Another aspect of the invention relates to a ski boot capable of being connected to a ski in a pin binding. The ski boot includes or forms a sole incorporating engagement structures that form receptacles for the pins of the pin formation to secure the shoe over the pins on the ski. The engagement structures are the functional surfaces of an insert, as described in detail on the preceding pages. The ski boot may be, in particular, a touring boot which is held in the pin binding in the front and rear jaws for skiing with the ski and which is pivotably mounted in the toe of the binding in order to be able to ascend in touring mode , On the buttocks, one or more climbing aids can be stored, depending on the terrain and according to the chosen by the athlete setting, the shoe when walking in touring mode supported in different angular positions.

In the following, embodiments of the invention will be explained in more detail with reference to figures. Features or combinations of features that can be found only in the figures belong to the scope of the invention and can advantageously further develop the invention individually or in the combinations shown and obvious.

The figures show in detail:

1 : Insert in one piece in four views;

2 : Insert the 1 in a perspective view;

3 : Insert of several parts in an exploded view;

4 : Insert the 3 joined in a perspective view;

5 : Insert the 4 in a plan view;

6 : another insert for several parts in an exploded view;

7 : Insert the 6 together.

The 1 shows an embodiment of a one-piece insert 10 in four views: a side view a), a plan view b) and two views c), d) on the end faces.

The insert 10 is made entirely from a single piece or molded from a single piece. The semifinished product used was a flow-molded part or a rolled profile, which was embossed or stamped, ground, routed to the insert 10 was formed.

The insert 10 has two distinguishable areas. At each end 4 . 5 is each a recording structure 2 formed, the area between the two receiving structures is as anchoring structure 1 educated. The insert 10 has in the exemplary embodiment on a cylindrical shape, whose receiving structure 2 forming end faces 4 . 5 towards the body, which forms the anchoring structure, are widened.

The anchoring structure 1 In the exemplary embodiment comprises two anchoring surfaces 6 . 7 , which are introduced into the solid cylindrical body, for example by milling. If the insert is now poured into the sole of a ski boot, the anchoring surfaces prevent it 6 . 7 in that the insert in the sole can move laterally and can pivot in the sole. The anchoring surfaces 6 . 7 can also be used as a tool engagement, for example, for an insertion tool with which the insert 10 is inserted into a tool, for example, to be poured into a shoe sole.

The recording structure 2 includes a functional area 3 in the form of an opening or depression, which is formed so that a pin of a pin binding engage in the functional surface and the shoe with the insert 10 secure in the pin binding.

By doing that, the insert 10 is made of a commercially available semi-finished, which is produced for example by means of hot rolling, cold rolling or cold drawing, can also easily a length of the insert 10 be changed so that for shoe models with different width sole in the backup area of the pins of the pin binding easily customized inserts 10 can be made.

There 1 only one embodiment of the one-piece insert 10 shows, it is clear to the person skilled in the art that the shape of the insert 10 can be chosen arbitrarily. A basic cross-section may, for example, be oval, rectangular, polygonal, flower-shaped, triangular, drop-shaped or wing-shaped or of any desired design. The anchoring structure 1 can have more or less anchoring surfaces 6 . 7 have and / or blind or through holes and optionally other other anchoring elements, for example, from the surface protruding structures, the anchoring of the insert 10 in the shoe sole are conducive.

The 2 shows in a perspective plan view of the insert 10 of the 1 , Alternatively, the insert 10 of the 1 also from an anchoring structure 1 and a separately prepared receiving structure 2 be formed, after making first to the insert 10 must be added. Such an inserted insert 10 is in a further embodiment in the 5 to 7 explained in more detail. The description of these figures can insofar also on the 1 be read when the insert 10 of the 1 not in one piece and preferably made of a material, but separate anchoring structures 1 and reception structures 2 having.

receiving structure 2 and anchoring structure 1 In this case, they can be joined together, for example, welded to the insert 10 of the 1 to build.

3 shows an insert in a perspective view 10 that comes from an anchoring structure 1 and a recording structure 2 exists, the recording structure 2 in the embodiment, two receiving part structures 2a . 2 B includes. It is clear that instead of the two receiving part structures 2a . 2 B the recording structure 2 may also be formed in one piece, similar or equal to the insert 10 that in the 1 is shown. That is, the insert 10 of the 1 can the recording structure 2 for the insert 10 of the 3 form, leading to the formation of the insert 10 with a separate anchoring structure 1 is added.

The receiving part structures 2a . 2 B can, how to 1 described, be made of a semi-finished product, such as a forged part, a Fließpressteil or a rolled profile. The anchoring structure 1 is a plate having in the embodiment, a plurality of openings or through holes into which the material of the sole can penetrate when the insert 10 For example, in the manufacture of the sole, for example, in a plastic injection or -gießverfahren injected into the sole with or poured.

The anchoring structure 1 will be separate from the recording structure 2 made and therefore may consist of a different material, as the receiving structure 2 , The material of the anchoring structure 1 may have a different hardness, strength, rigidity or ductility than the material from which the receiving structure 2 , respectively the receiving part structures 2a . 2 B are made. So can the anchoring structure 1 be formed for example of a commercially available structural steel, while the receiving structure 2 consists of a stainless steel, which is additionally hardened, coated or post-processed in other ways, at least in some areas and / or post-treated.

In the embodiment of 3 lie the receiving part structures 2a . 2 B on two sides plan on plan flanks of the anchoring structure, as in the 4 and 5 is shown. In this position, the recording structure 2 and the anchoring structure joined together, for example, welded together, brazed or glued. When welding, for example, fillet welding is considered, preferably in a gas-shielded welding process.

Alternatively, the anchoring structure can 1 and the recording structure 2 also partially overlap and / or the anchoring structure 1 can be partially in the recording structure 2 engage, or vice versa, for example, in a groove and / or an opening. In such embodiments, instead of fillet weld welding, for example, a resistance welding or spot welding process may be used to provide the anchoring structure 1 and the recording structure 2 to add to the insert.

The 6 and 7 show an insert 10 for example, which may be connected to a rearward end of the sole in the skiing direction to receive a pin of the heel holder or buttock when the binding is used in downhill mode. This insert 10 but can also be prepared alone or in addition, to receive and keep a backup tape, which prevents that during a tour, the ski can not move too far from the athlete when the bond is triggered. This band then replaces a ski brake in touring mode, which automatically triggers in downhill mode when the binding unintentionally opens and crashes.

In Embodiment 1, the anchoring structure comprises two cylindrical pins 8th . 9 which can be connected to the sole of the shoe. At the pins 8th . 9 these may be, in particular, impact extrusion pens. The recording structure 2 is made, for example, from a stamped and bent part and with the pins 8th . 9 connected.

For joining, the already mentioned welding methods, such as spot welding and resistance welding, can be used. Alternatively, the pins 8th . 9 with oversize in a blind hole in the receiving structure 2 be pressed.
