    The invention relates to a device for producing a partially adapted to a foot or a leg of a user shell of a ski boot with a lower and / or upper shell part of a plastic material, wherein a heating element for heating portions of the and / or upper shell part on the softening temperature of Plastic material is provided. Furthermore, the invention relates to a method for producing a adapted to a foot or a leg of a user shell of a ski boot having a substantially plate-shaped sole region, prefabricated lower shell part and / or an upper shell part made of a plastic material, wherein one of the shell parts at least partially is heated, wherein the foot of the user is received in the heated state in the lower and / or upper shell part.
    From WO 2014/015354 Al a method and an apparatus for the partial heating of a ski boot shell part is already known. Here, a heating mat is used, which is wound around the ski boot. By means of a Velcro fastener or the like, the two ends of the heating mat are connected to each other, so that the heating mat at least partially in contact with the shell part to achieve an efficient heat input. Basically, this device works satisfactorily, but the heat input can be determined only relatively inaccurate, so that usually a larger area of the shell part is heated, as would be required for an individual adaptation in a critical area. This can lead to the ski boot or the shell part unintentionally changing its basic geometry at least in part, which can adversely affect the force transmitted to the ski via the shoe. In addition, only a relatively low efficiency in the heat transfer is achieved due to the loose support of the heating mat.
    From WO 2011/153567 Al further an adaptation method with a bag-shaped printing element is known. However, the method or the known device requires adjustment of an alpine ski boot exact positioning of the bottom plate during the implementation of the adaptation process, so that it does not unintentional deformation of the im in adapting the shell of the ski boot to the individual foot or leg of the user Substantially plate-shaped sole area comes.
    In addition, EP 1 872 678 A2 discloses a ski boot which largely consists of a comparatively stiff plastic material. In those areas in which often painful pressure points occur, the ski boot has a lower softening temperature exhibiting material, so that the ski boot is deformable when heated to a specific softening temperature only in the range of these neuralgic areas. Such a production of a ski boot, which sections of different plastics or Kunststof fmischungen is, however, is extremely expensive and expensive.
    In the case of ski boots, deformation of the sole region is particularly disadvantageous, since the shape of the sole region contributes substantially to the safety and stability of the connection between ski and ski boot. In contrast, in a skate according to WO 02/28215 A1, the entire skate including the sole is heated, completely enveloped and pressurized from the outside and thus potentially deformed.
    The aim of the present invention is therefore to provide a device or a method, with which or with which a precise heating of a specific area of the shell part is made possible. Preferably, moreover, an improved efficiency in heat transfer should be achieved.
    According to the invention, this is achieved with a device of the initially mentioned type, in which the heating element has an external adhesion-promoting layer for connecting the heating element to a shell part of the ski boot. By providing a heating element with an adhesion-promoting layer, the
    Heating element are attached at any point of a shell part in a simple manner by means of adhesive bond. The contact between the heating element and the shell part, which is produced via the adhesive bond, additionally achieves improved heat transfer from the heating element into the plastic material of the shell part, in contrast to a loose support. With the device according to the invention a precise and efficient partial heating of the shell part is achieved in a specific area of the shell part. In this case, the heating element can be fastened in particular in so-called critical areas on the shell part, in which there are often painful pressure points when using the ski boot. These are especially ankle outside, small toe bales, base bumps or on the inside of the ski boot ankle inner side, big toe ball and scaphoid bone.
    In order to be able to produce an adhesive connection between the heating element and a shell part in a simple and efficient manner, it is favorable if an adhesive layer is provided as an adhesion-promoting layer.
    If the adhesive layer has a re-adhesive pressure-sensitive adhesive, the device according to the invention can advantageously be reused; i.e. the heating element can first be reliably fixed in a neuralgic area to be fitted to the user's foot with the aid of the pressure-sensitive adhesive, and after adaptation in this area removed from the shell part, positioned in another area to be adapted, etc.
    In order not to soften too much in the heat emitted by the heating element and thus to ensure that during the heat transfer, a contact contact between the heating element and shell part is given, it is advantageous if the adhesive layer has a wiederverklebbaren pressure-sensitive adhesive. Tests have shown that particularly satisfactory results are achieved with the "A20" acrylate adhesive sold by 3M Deutschland GmbH or with adhesive tapes sold by Lohmann GmbH & Co KG under the trademark Duplexloc®. ) Pads available from Axelgaard Manufacturing Co. Ltd, which have an acrylate-based adhesive layer which is well suited as an adhesive layer for the device according to the invention.
    As an alternative to an adhesive-comprising primer layer, it is also possible that a Van der Waals forces-based primer layer is provided. Here, the adhesive surface on a variety of finest hairs, each hair due to electrostatic interaction can transmit a small force by the high number, the sum of the forces for this from - as in the present case - the heating element on the shell part for the purpose of heat transfer due to the electrostatic Attached interaction. Such based on the so-called "gecko effect" mats are well known and are available from various suppliers, including as anti-slip mats for cars and the like on the market.
    In order to keep weight and material thickness of the heating element low, so that the heating element is already held with comparatively small forces on the shell part, it is advantageous if the heating element has a heating foil, preferably with a foil thickness of less than 3 mm. As an alternative to a heating foil, it is also possible to use what are known as silicone heaters, in which heating conductor tracks are embedded in a moisture-protected manner between two thermally and mechanically resistant silicone layers as a strand, wire or etched foil.
    Advantageously, in the heating foil an etched in sheets Heizleiterschicht, preferably from a copper and / or Ni-ckel-containing alloy added. It is advantageous if the free spaces between the tracks of the heat conductor layer are formed such that the heating foil is deformable in all three dimensions and thus can best adapt to the three-dimensionally shaped surface of the shell part.
    Furthermore, it is favorable for the protection of the heat conductor layer without significantly impairing the heat transfer efficiency if the heating conductor layer is accommodated between two insulating foils, preferably made of polyimide (so-called Kapton® heating foils), or polyester. Such heating films with a Heizleiterschicht recorded between two insulating films are also available on the market and are e.g. manufactured by Winkler GmbH, Heidelberg, Germany.
    In order to limit the heat emission in the direction away from the shell part direction, it is advantageous if a textile fabric and / or an insulating layer are provided on the side facing away from the adhesion-promoting layer side of the heating foil.
    In order to be able to control to a desired, preset temperature, it is advantageous if the heating element has a temperature sensor.
    Furthermore, it is favorable if the adhesion-promoting layer extends substantially completely over a contact surface of the heating element. In this case, it is ensured that the contact touch substantially extends over the entire contact surface due to the substantially continuous adhesion-promoting layer, so that a particularly efficient heat transfer can be achieved.
    The method of the type mentioned is inventively characterized in that in a deviating from the sole region region of the lower shell part, a heating element is attached by means of an adhesive bond, before the lower shell part is heated in regions over the heating element.
    Thus, as already explained in connection with the device, it can be achieved, in particular, that the shell part is heated partially and precisely to heat the shell part locally in neuralgic regions above the softening temperature and thus without the basic geometry of the shell (over a large area) ) - To adapt the shell part partially to the foot of the user. Accordingly, painful pressure points can be avoided when using the ski boot without sacrificing the power transmission.
    In terms of ease of handling, in which it is not necessary to manipulate the at least partially heated shell part, it is advantageous if the foot or the leg of the user is introduced into the lower shell part, before the lower shell part is heated.
    On the one hand, to achieve the softening temperature of the preferably hard thermoplastic material of which the lower and / or upper shell part usually consists, in the heated area, but without causing heat inside the ski boot, which would be uncomfortable for the user, it is beneficial when the lower shell part to at least 50 ° C, preferably to a temperature between 50 ° C and 100 ° C, in particular between 60 ° C and 90 ° C, is heated.
    The invention will be explained in more detail with reference to preferred embodiments illustrated in the drawings, to which, however, it should by no means be restricted. In detail, in the drawings:
    Figure 1 is a lateral side view of a known ski boot with a lower shell part and a pivotally mounted sleeve.
    FIG. 2 shows a medial side view of the ski boot according to FIG. 1; FIG.
    Fig. 3 is a view of the ski boot with an adhesive heating element (partially shown);
    4 shows a view of an embodiment of a heating conductor layer of a heating foil;
    5 shows a view of an alternative embodiment of a heating conductor layer of a heating foil; and
    Fig. 6 is a schematic sectional view through a heating element according to the invention.
    Figures 1 and 2 show a known ski boot 1 with a lower, consisting of a hard, thermoplastic plastic shell or shaft part 3, on which an upper, cuff-shaped shell part 3 'is pivotally mounted. In the shell parts 3, 3 ', a comparatively flexible, at least partially a padding having liner 5 is added. The lower shell part 3 and the upper, sleeve-shaped shell part 3 'each have closure elements 4, in particular buckles, on to allow easy entry or sufficient support of the foot or leg of the user in the recorded position.
    The lower shell part 3 in this case has a plate-shaped sole region 5 for the purpose of connecting the ski boot 1 to a safety binding. In Fig. 1 and 2, those critical areas are shown in broken lines, in which it can often lead to painful pressure points when using the ski boot 1. These are ankle outside 6, small toe bales 7, base bumps 8 or on the inside of the ski boot 1 ankle inner side 6 ', big toe bale 7' and navicular 8 '. In all these critical areas, in particular a heating element 10 (see Fig. 3) can be attached by means of an adhesive layer 11.
    In Fig. 3, the heating element 10 is shown in its adhering substantially in the region of the base hump 8 position. In this case, it can be seen that, via the illustrated heating conductor layer 12 (omitting the layers arranged above it, see Fig. 6), the shell part 3 can be heated precisely and only in a predetermined region by means of heat transfer via the softening temperature of the plastic material, and thus in this area and only in this area, in which the heating element 10 is provided, an adaptation to the foot of the user takes place.
    As can be seen in the sectional view according to FIG. 6, the heating conductor layer 12, which usually has a thickness of less than 2 mm, is received in a liquid-tight manner between two insulating foils 13, thus forming an inherently insulated heating foil 14 known per se, as for example from Winkler GmbH, Heidelberg, Germany.
    Above the heating foil 14 in the embodiment shown in Fig. 6, a cover layer 15 is disposed of a textile fabric, which is advantageously provided with a thermal ink, so - depending on the temperature - the color of the textile fabric changes, and thus for the user current temperature of the heating element 10 is made easily recognizable. In addition, one, preferably transparent, insulating layer 16 is provided in order to keep the heat radiation away from the shell part 3 low and in case of contact, for example, with the hand of the user to withhold burns of the skin.
    In FIG. 3 it can further be seen that the heating conductor layer 10 has electrical connection points 17 for connecting electrically conductive cables for connection to an external energy source, wherein in the embodiment shown, two separate heating conductor tracks 18 each have their own connection point 17, each with two contact points.
    The heating element 10 thus lies with a lower contact surface 19 essentially entirely on the shell part 3, so that heat transfer from the heating element 10 to the shell part 3 can take place in an efficient and precise manner. In this case, advantageously, the entire contact surface 19 is provided with the adhesion-promoting layer 11, so that a large-area contact between the heating element 10 and the shell part 3 is ensured via the adhesive bond.
    FIGS. 4 and 5 show two further preferred embodiments of a heating conductor layer 12. In this case, it can be seen in particular that both conductor tracks 18 are configured such that the heating conductor layer 12 can be deformed three-dimensionally in each case and thus can be adapted particularly well to the three-dimensional shape of the shell part 3.
    In order to eliminate the above-mentioned critical areas with a heating element 10, in which a heating conductor layer 12 - as shown in FIGS. 4 and 5 - individually, i. separately from one another, to be able to adapt to the foot of the user, the Heizleiterschicht 12 shown in Figure 4 has a diameter between 70 mm and 90 mm, in particular substantially 75 mm; the heating conductor layer 12 has a longitudinal extent between 80 mm and 120 mm, in particular substantially 100 mm, and a width between 40 mm and 80 mm, in particular essentially 60 mm.
    In order to keep the manipulation effort low in the adaptation, the foot or the leg of the user is preferably already arranged in the ski boot 1, before using a heating element 10, the plastic fmaterial of the shell part 3 only in the desired area and without to change the basic shape of the shell part 3 is heated above the softening temperature.
