Heated shoes, especially ski boots.

The innovation relates to a shoe, especially ski boots, with a heating insert for electrical heating the inside of the shoe .;

Already at the turn of the century TorSQiiläge was maneuvered to artificially heat winter footwear. For example, a hollow insole made of copper sheet is described in which an electrically heated hot water circuit is provided in the heel part. Another Torschlag sees the rear shaft end of the shoe äussen mounted chamber before ,, installed in der'eine heat source from which ausgeht.und from a silver wire or otherwise in good thermal conductor ^ ■ - \ is guided over the sole area of the shoe .. Ils j Heat sources are 'G-Lühstoffpatronen, spirit etc. lamp-: ij chen and finally. a light accumulator suggested. These! Solutions may be considered obsolete due to the advanced technology. ·

More recently, goalscoring has become known, one of which

provides an insole that contains chemical substances that release heat when they come together. Be this exothermic process is initiated by a Anreissfadens and can neither regulated nor interrupted "* Such soles give accordingly over a longer period of time constantly off heat, regardless of whether the shoe is used or not. A large part of the heat is therefore lost unused; even with cost-reducing mass production, this solution must therefore be viewed as uneconomical. Another goal is a specially constructed electric battery with a heat-dispensing core, which is pushed under the shoe, either into the sole or the heel into a cavity provided for this purpose. The ·. Heat distribution on the shoe sole is therefore different, specially designed batteries have to be used which, due to the limited space inside the bottom of the shoe, can hardly give off a sufficient amount of heat over an economically longer period of time. The slide-in technology complicates shoe design and must guarantee a watertight seal, at least for the battery itself. A further development of this proposal provides, instead of the battery, an electric storage cell of modern design that can be recharged repeatedly using mains current and is also inserted as an insert in the heel area of the shoe. When it is pushed in, the cell is connected to a heating insert built into the bed, which works according to the heating pad principle * so that ■ here the entire shoe sole is more or less even

is heated. A disadvantage can also be seen here in the fact that these memory cells only have to be produced for this purpose, thus elude large-scale production and in their capacity _t - · '. are limited due to the possible size. Here too, at least the cell must be made absolutely watertight.

All of these suggestions have in common that theirs. Energy sources must be adapted to this specific purpose of the shoe heating according to size and shape. That means in the age of large-scale production and the modular principle, in which one and the same building block is to be accessible, to be available for a wide variety of purposes, a unpleasant and avoidable increase in the cost of Schuhbeh.ei-Büng. The advantage that you carry the energy dispenser with you arranged in the shoe itself and thus any supply lines of energy sources outside the shoe * appears on the other hand bought at a high price. . '

It is therefore the task of the innovation, winter footwear, in particular also for sporty people. Purposes, with an electrical Equip resistance heating and this for connection '^

to provide electrical energy sources with suitable electrical connections and connection options ». So that should one compared to the previously electrically heated shoes:; Simple and robust design of the footwear as possible can be achieved and the most economical heating possible

to be guaranteed. Taking advantage of the known electrotechnical Circuit options for electrical resistance heating should be a step-by-step variation of the amount of heat emitted and / or the selection of one that is preferably to be heated Part of the sole, for example the toe, can be made possible. to equip the shoe with a heat accumulator in order to with. approximately constant heat emission in intervals to allow heating to take place, whereby the possibility is given to the shoe for the duration of the · heating intervals Connect to a stationary energy source.

There is a first solution to this problem in accordance with the innovation therein, the heating insert worked into the shoe bottom in a known manner with one arranged away from the shoe to connect electrical energy source in such a way that the electrical Yer ^ Connection lines lead into an easily detachable galvanic coupling, the shoe-side of which is connected to the heating insert Coupling part is arranged on the shoe.

Basically, this shoe side coupling part is at any point of the shoe attached, to be provided for example in a the shoe upper, small pocket, "A zweckmäs- ¹ sige embodiment provides admit the shoe side coupling part side in the heel portion of the shoe bottom, where it is expedient, the coupling member in, to arrange the heel side facing away from the Kaehbarschuh to avoid damage to the coupling by hitting one another

In such a manufacturing process, the shoe-side coupling part can advantageously also be embedded in the sole mass and thus held Mistake. In shoes of this type, heel wedges made of wood or the like are generally used, which are also embedded in the outsole compound. In these cases, the coupling part on the shoe side is stored in a recess in the heel wedge, which makes it easier to cast in the correct position *

As a rule, this does not cause any problems. on the other hand it can, for example, when using separate, single-core Supply lines make sense, each of the individual connections with a separate, single-pole coupling part to connect * Here it should now be expressly pointed out that the implementation of an I heated shoe the connection to the most diverse I.

The so-called heating insert consists in its simplest ί

Form ■ only, from the resistance wire. In order to achieve the most uniform possible distribution of the amount of heat supplied to the foot, it is useful to arrange a highly thermally conductive layer, preferably made of copper, between the resistance wire and the sole layer arranged over it. In order to prevent the copper foil from short-circuiting the individual sections of the resistance wire, it must be insulated from the resistance wire. In principle, it is possible, at the low temperatures required here, to provide the wire with insulation, for example a protective layer, which should have the highest possible thermal conductivity. Another possibility is to provide an insulation layer between the thermally conductive I ¹ Olie and the resistance wire, which should also have good thermal conductivity and which can expediently be perforated in various ways to enable heat radiation and heat flow from the resistance wire to the thermally conductive SOlie. On the other hand, it is necessary to limit the heat dissipation towards the outsole of the shoe as much as possible * For this reason, a heat-insulating layer must be provided below the resistance wire, which must also have an electrically insulating effect when the resistance wire is uninsulated. An asbestos layer, for example, is suitable for this purpose. If one also wants to prevent possible heat radiation to the outsole, then this heat-insulating layer can have a "film" that absorbs the heat radiation.
