    iPrintedi26 «2012 E014.1: 102012/50290 1
    The invention relates to a method and an apparatus for producing a shell of a ski boot adapted to a foot or a leg of a user with a prefabricated lower shell part made of a plastic material and having a substantially plate-shaped sole region.
    From WO 2011/153567 Al an adaptation method with a bag-shaped pressure element is already known, which also works properly in practice. 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.
    From EP 1 872 678 A2, on the other hand, a ski boot is known, which largely consists of a comparatively stiff plastic material. In those areas where painful pressure points frequently occur, the ski boot has a material which has a lower softening temperature, so that the ski boot can only be deformed in the area of these sensitive areas when heated to a specific softening temperature. Such a production of a ski boot, which consists in sections of different plastics or plastic mixtures, however, is extremely expensive and costly.
    The aim of the present invention is therefore to provide a method and a corresponding device which on the one hand in a simple manner, the adaptation of the shell of the ski boot to the foot or leg of the user in those areas where usually painful On the other hand, however, it is ensured that no unwanted deformation in other areas, in particular in the region of the substantially plate-shaped sole region, occurs. 2
    According to the invention this is achieved in the method of the initially mentioned type in that the lower shell part is heated at least partially above the softening temperature of the plastic material with the exception of the substantially plate-shaped sole region and the foot or the leg of the user is received in the heated state in the lower shell part ,
    The heating of the shell part, with the exception of the essentially plate-shaped sole region, above the softening temperature of the plastic material of the ski boot reliably ensures that deformation of the lower shell part in the region of the substantially plate-shaped sole region is avoided. Accordingly, such a method is uncritical in its execution in comparison to previously known methods in the application and can be carried out in particular by untrained personnel. In addition, it is provided that the foot or the leg of the user is received in the heated state in the lower shell part, thereby advantageously the foot or the leg of the user even as a kind of punch for adapting the lower shell part to the individual foot or the Leg of the user acts. Thus, an additional printing device for the purpose of adapting the lower shell part to the foot or leg of the user is in particular not necessarily required in the region of those neuralgic sites where usually painful pressure points occur. Advantageously, thus, the lower shell part can be made in one piece and consist of a single plastic material, so that the softening temperature of the entire lower shell part including the plate-shaped sole region or the sole plate is substantially constant; i.e. it is not necessary to provide different plastic compositions in different sections.
    In order to reliably achieve a deformation of the lower shell part without heating the essentially plate-shaped sole region above the softening temperature of the plastic material, it is advantageous if the heating of the lower shell part takes place via a heating element by means of heat conduction or heat radiation.
    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 shell part usually consists, but without causing heat development in the interior of the ski boot, which would be uncomfortable for the user, it is advantageous if the lower shell part to at least 50th ° C, preferably to a temperature between 50 ° C and 100 ° C, in particular between 60 ° C and 90 ° C, is heated.
    In order to achieve an improved adaptation of the lower shell part to the foot or the leg of the user in addition to the pressure of the foot or leg which acts from the inside on the lower shell part, it is furthermore advantageous if the lower shell part is in the heated state is inserted into a sleeve-shaped pressure element substantially enclosing at least the lower shell part, wherein the pressure element consists at least partially of a deformable, cavity-limiting material, wherein to form the cavity the pressure element has an inner layer which is tightly connected to an outer layer, and a pressure applying fluid is introduced into the cavity, so that at least the lower shell part is at least partially adapted to the user's foot or leg. With the help of the envelope-shaped pressure element, a pressure on the above the softening temperature of the plastic material heated shell part is thus applied not only from the inside but also from the outside, so that an intimate adaptation of the shell part to the foot or the leg of the user is achieved. As an alternative to this, with a pressure-applying pressure element, a bandage applied under tension can also be provided at least in sections, from the outside a compressive force for the purpose of intimate adaptation of the shell part to the foot or the Leg of the user to effect.
    When the pressure application fluid is introduced into the pressure element at an inlet pressure higher than an outlet pressure of the simultaneously discharged pressure application fluid, a steady flow of the pressure application fluid can already be achieved during the pressure application, thereby consistently flowing cold fluid and thus advantageously cooling the previously heated shell part is accelerated.
    Furthermore, it is favorable for an efficient cooling of the previously heated shell part and thus a quick adaptation to the foot of the user, if after reaching the softening temperature of the plastic material, preferably before introduction of the pressure application fluid in the pressure element, a lower shell part at least partially covering cooled cuff on the lower shell part is slipped.
    In order to easily ensure that the heating element is arranged such that those portions of the lower shell part are heated in which an adjustment is desired, it is advantageous if the heating element is inserted into the pressure element before the lower shell part is heated and then the pressure application fluid is introduced into the pressure element.
    The device of the initially cited type is characterized in that a heating element is provided for at least partially heating the lower shell part above the softening temperature of the plastic material of the lower shell part, with the exception of the substantially plate-shaped sole region.
    Also with the help of the device according to the invention is thus ensured that the shell part heated only in those areas above the softening temperature of the plastic material
    5 is / in which an adaptation of the shell part to the foot or the leg of the user is desired. In particular, an unwanted deformation of the substantially plate-shaped sole region is thus excluded, so that with the aid of the device, the production of an adapted shell part of a ski boot is also ensured by untrained personnel.
    In order to ensure a targeted heating of the shell part without heating the substantially plate-shaped sole region above the softening temperature of the plastic material, it is advantageous if a heat-conducting or a heat radiation source is provided as the heating element. In particular, it has been found to be advantageous that a heating mat is provided as a heating element. Such a heating mat can be advantageously positioned in a space-saving manner directly on the shell part, which reliably ensures that only those areas on the
    Softening temperature of the plastic material are heated, in which an adaptation to the foot or the leg of the user is desired.
    With regard to an efficient heating of the shell part, it has proven to be advantageous if the heating mat has at least one heating wire, a silicon heating element, or a carbon fiber heating element. Such heating mats are known in the art, especially for heating vehicle tires.
    In order to achieve an adaptation of the ski boot not only by acting in the manner of a stamp in the shell part recorded foot or leg of the user, but at the same time on a pressure applied from the outside an intimate adaptation of the shell part to the foot or the leg of the user reach, it is favorable if a at least the lower shell part substantially comprehensive pressure element is provided with a receptacle provided for receiving at least the lower shell portion receiving space, wherein the receiving space is at least partially bounded by a deformable material having an inner layer of the
    26-07-20 * 2 i] EÖ141 il02012SO29O 6 forms a cavity enclosing pressure element having an opening provided for introducing a Druckaufbringungsfluids inlet opening, which preferably has an inlet valve designed as a controllable pressure relief valve.
    If an outlet opening is provided, which is provided with an outlet valve preferably designed as a controllable pressure relief valve, a discharge of the pressure application fluid via the outlet opening can be achieved immediately with the introduction of the pressure application fluid, so that a permanent air flow is achieved in the pressure element. As a result, constantly cool fluid can be replenished during the pressure application and thus the cooling of the previously heated shell part can be accelerated. For example, to ensure positive pressure between the inlet and outlet ports, the outlet pressure may be reduced to e.g. 0.6 bar, whereas the inlet pressure can be adjusted to approx. 0.8 bar.
    With regard to a simple low-cost embodiment of the printing element, it is advantageous if the inner layer and preferably also the outer layer consists of a coated fabric. The formation of the inner and outer layers from a coated fabric results in a pressure element, as is known essentially from air mattresses consisting of coated fabrics and the like. · -
    In order to achieve a reliable arrangement of the heating mat with respect to the lower shell part, it is advantageous if the inner layer of the pressure element or the heating mat have cooperating fastening elements. In this case, the heating mat can be easily removed by the co-operating fasteners, e.g. from a hook and loop fastener or the like, in which pressure elements are positioned, the lower shell part is then positioned in the sleeve-shaped pressure element and thus immediately the correct arrangement of the heating mat is ensured with respect to the lower shell part.
    In order to be able to easily receive the lower shell part in the hull-shaped pressure element and at the same time to achieve an intimate enclosure of the lower shell element by the pressure element before introduction of the pressure application fluid, it is advantageous if the scope of an associated with the receiving space entry opening on the opening of at least one closure element is increased. Here, for example, a quick release, e.g. a zipper, be provided in the instep area of the pressure element.
    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.

    7 shows a perspective view of the ski boot, which is accommodated in a pressure element together with a heating mat;
    Fig. 8 is a sectional view according to VIII-VIII in Fig. 7; iPnnted: 26 ^ 7-201¾ (Ε014.Ϊ 10 2012/50290 8
    9 shows an oblique view of a cooling collar;
    FIG. 10 shows an oblique view of the cooling sleeve of FIG. 9 slipped over the shell part; and
    Fig. 11 is a view of a ski boot with a bandage for the purpose of pressure application.
    Figures 1 and 2 show a known ski boot 1 with a lower, consisting of a hard, thermoplastic plastic shell or shaft part 2, on which a sleeve 3 is pivotally mounted. The lower shell part 2 and the sleeve 3 each have closure elements 4, in particular buckles, in order to allow a simple entry or sufficient support of the foot or leg of the user in the recorded position.
    The lower shell part 2 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 usually come to painful pressure points when using the ski boot 1. These are knuckle outside 6, small toe bales 7, base humps 8 or on the inside of the ski boot ankle inner side .6. ', Big toe ball 7' and navvy 8 '.
    FIG. 3 shows an embodiment in which the device for producing a shell of a ski boot adapted to a foot or a leg 11 of a user has a heating element 9 in the form of a radiation source. With the aid of this radiation source 9, the lower shell part 2 can be partially heated in such a way that the aforementioned neuralgic areas are heated above the softening temperature of the plastic material. Here, e.g. an infrared radiation source or a laser radiation source, the radiation being oriented in such a way that the above-mentioned critical regions 6, 6 ', 7, 7', 8, 8 'are heated above the softening temperature of the plastic material, other parts 9 of the ski boot 1, In particular, the plate-shaped sole portion 5 and the cuff 3, however, are not heated above the softening temperature, so that in these areas of the ski boot 1 also no adaptation to the individual foot or the leg 11 of the user takes place.
    In order to minimize the manipulation effort, as shown in Figures 3 and 4, the foot or leg 11 of the user is already disposed in the ski boot 1, before using a heating element, i. Radiation source 9 and a heating mat 10, the plastic material of the lower shell part 2 is heated above its softening temperature.
    4 and 5, an electrical heating mat 10 is shown, in which in a sheath, preferably made of flexible textile material, preferably electrical resistance wires are incorporated. Such heating mats 10 are well known in particular for heating vehicle tires. To activate the heating mat 10, the heating mat 10 is connected to a power source via a plug 12, wherein the heating mat 10 has a temperature control device 13 in order to regulate the heating temperature in the desired range, preferably between 60 ° C and 90 ° C.
    Moreover, it can be seen in Figures 4 and 5, respectively, that the heating mat 10 includes closure means 10 ', e.g. in the form of Velcro straps, with corresponding counter-elements, so that the heating mat 10 can be easily positioned in the desired position on the ski boot 1 in order to avoid the above-mentioned critical areas 6, 6 ', 7, 7', 8, 8 ' to heat reliably.
    FIG. 6 shows a heating mat 10, which essentially has a continuous Velcro fastener tape 10 "in its upper edge section, which can then be accommodated with a corresponding counter element in the pressure element 14 shown in FIGS. 7 and 8. In order to enable a simple arrangement of the ski boot 1 in the pressure element 14 and at the same time to sufficiently close the ski boot 1 even in the non-pressurized state, the pressure element 14 has a quick-release closure in the instep region in the form of a zipper 15.
    In Fig. 8 it is then seen that the heating mat 10 can remain in the pressure element 14, while the pressure element 14 at the inlet opening 16, a pressure application fluid, in particular air, and via an outlet opening 16 ', the pressure application fluid is discharged again. In this case, the envelope of the heating mat 10 extends into the region of the sole plate or the plate-shaped sole region 5. However, the heating elements, in particular resistance heating wires, accommodated in the heating mat 10 are arranged in the heating mat 10 such that the sole plate 5 is not heated ie is not heated above the softening temperature of the plastic material. Due to the overpressure, an efficient cooling of the ski boot 1 can be achieved simultaneously with the pressure application from the outside via a cooled air supply.
    In Figure 9, a cooling sleeve 17 is shown. This cooling cuff 17 includes a coolant, e.g. a cooling gel filled in a cavity formed by deformable films and may be placed over the shoe 1 to accelerate the cooling of the shell part 2 below the softening temperature of the plastic material. In order to cool the gaiter 17, it is prevented from slipping over the shoe 1 in a refrigerator, e.g. a freezer, strongly cooled and then placed on the shoe 1.
    As shown in Fig. 10, - after heating the shell part 2 - only after the Kühlgamasche 17 was placed around the shell part 2, the pressure element 14 can be activated. Subsequently, the pressure element 14 is closed by the closing means 15 and, as already described above, an overpressure is built up via the introduction of compressed air, so that the inner layer 14 'of the pressure element 14 conforms to the outer surface of the cooling belt pocket 17. The 11 Kühlgel taken in the gaiter 17 then transmits in principle the hydrostatic pressure from the pressure element 14 on the surface of the shoe 1. The contact between the Kühlgamasche 17 and the heated shoe surface there is a very good heat conduction and rapid cooling of the Shoe 1 in the shape adapted to the foot or the leg 11 of the user.
    In Fig. 11, for the purpose of a simple pressure application, instead of the pressurized member 14 pressurized by a fluid, there is shown a cuff formed from an elastic bandage 20 in the form of an ankle bandage. The napkin 20 may be made of an elastic material, e.g. elastic fabric or a flat rubber or the like, be prepared to also like the pressure element 14 to press in the neuralgic areas 6, 8 and 6 ', 8' the lower shell part 2 to the foot of the user, thus an intimate Adjustment of the shoe to achieve the individual foot of the user.
