Definitions

• the present invention relates to a method for He warming of the foot of the wearer of footwear as well as an insole for footwear with an arrangement for Generating heat.
• the present invention is now based on the object de, a method or an insole of the ge initially called way of creating that or that in a simple and reliable way of generating heat, without the need for an external source of energy.
• the present invention makes use of the forcible walking Current alternating stress in the area of the heel and the ball of the foot or toes.
• the medium is through the throttle put it back through it into the other cavity urges.
• the Throttle point is generated in the sole, which is used to Warming of the foot of the wearer of the footwear wearing.
• An insole of a similar type is from US-PS 3.87l, ll7 known.
• This insole also has a a liquid-filled cavity that passes through Partition walls are divided into a variety of chambers.
• This cavity is in the area of the tip of the foot and in the Heel area to a cooling arrangement arranged in the footwear connected through which the liquid when walking is pushed out of the cavity.
• a cooling arrangement arranged in the footwear connected through which the liquid when walking is pushed out of the cavity.
• one-way valves are on inside the cavity orderly. In this sole heat is generated treatment in the shoe is specifically counteracted.
• An insole is also disclosed in US Pat. No. 4,123,855 of the aforementioned type known, which consists of two ent formed along the edge of interconnected foils is, which encloses a liquid-filled cavity sen. This cavity is also baffled, wel surface formed by partitions, divided. These Chicanes prevent the liquid from rising when walking displaced directly from back to front and vice versa becomes. With this measure there is an increased massage effect aimed at.
• This insole is further with a Number of continuous ventilation openings provided, which run transversely to the longitudinal extent of the sole. With The purpose of these ventilation openings is that a He warming of the foot is prevented, which means that also with this sole a heat build-up in the footwear is counteracted.
• FIG. 1 shows a Inner sole 1, in which a recess 2 is cut out is.
• the recess 2 is used to accommodate a while walking activatable device for generating heat.
• the insole l can either be used as the footbed of a shoe designed and thus be part of the shoe or a one be insoles that are inserted into a shoe. Is the sole l is part of a shoe, the recess 2 lies preferably in the insole and in part of the Sole leather.
• the sole l can be made of rubber or plastic different strengths and profiles exist. Preference The sole l is wisely foamed from plastic.
• the device housed in the recess 2 for Heat generation is based on the embodiment according to Fig. 1 from a number of hollow bodies 3, 4, 5, 6 together, which are all executed the same.
• Each hollow body 3 - 6 consists of a tube 7, which at its ends 8, 9 ver is closed and from one arranged in the tube 7 Throttle element l0.
• the throttle element l0 divides the Hollow body 3 - 6 in two partial cavities ll, l2, which are in the area of the heel or ball of the foot.
• the Throttle element l0 lies approximately in the middle area of the sole l, i.e. in the area of the arch of the foot.
• the tube 7 is made of a flexible material, e.g. a plastic with low elasticity, and can be a circular, oval, rectangular or polygonal or one have another suitable cross-section. Used as a cross cut the tube 7 a narrow rectangular cross cut, the tubes form a plate-shaped one Body of low strength, which can easily be inserted into the sole l can be accommodated.
• a flexible material e.g. a plastic with low elasticity
• Fig. 2 is a further embodiment of a sole l shown, in which instead of the partial cavity ll, or l2 of the hollow bodies 3-6 in FIG cavity l3 or l4 is present.
• the sole l says so with a closed cavity l5, which is from an im Section shown, elastically deformable wall l6 is surrounded.
• the wall thickness of the wall l6 can also be any be designed big and wall thicknesses of different thicknesses ken, e.g. in the toe area l7, in which the Wall thickness is increased.
• the two partial cavities l3 and l4 are ge by a throttle element 20 from each other separates, which lies in the area of the arch of the foot.
• the throttle elements l0, 20 throttle channels 2l, which the partial cavities ll, l2 or l3, l4 connect with each other.
• the partial cavities ll, l2 and l3, l4 are with a suitable liquid or filled with a suitable gas.
• a fluid is used that in the occurring temperatures, e.g. between -30 ° C to + 40 ° C, has a constant toughness.
• Figs. 3 to 6 are some examples of possible out leadership forms of the throttle element l0 or 20 with the Throttle channels 2l shown.
• this is the throttle element ment l0, 20 a substantially rigid body, e.g. made of plastic, in which the throttle channels 2l are arranged are.
• the throttle channel 2l shown in Fig. 3 is in the kind of a capillary 25 with a straight course forms.
• Fig. 3 it is also shown that the hollow body 3 - 6 or the cavity l5 with additional Layers 22, 23 are covered, the layer 22 an insulating layer, e.g. as part of the sole leather can.
• the cover layer 23 shown in dashed lines can e.g. made of leather, plastic or another suitable one Material and serve as a support for the foot.
• the throttle element l0, 20 according to FIG. 4 has the same as in the embodiment according to FIG. 3 also one capillary-shaped throttle channel 2l.
• this Throttle element l0, 20 is an adjustable in its position Barer pin 26 arranged with which the passage can be more or less narrowed through the channel 2l. The heat development in the throttle element l0, 20 be dosed.
• FIG. 5 shows, the throttle element 10, 20 instead of with throttle channels 2l with one or more orifices 27 be provided.
• Fig. 5 there is only one throttle screen 27 shown, but it is also possible in the body of the Throttle element l0, 20 two or more diaphragms 27 to organize.
• the throttle element 10, 20 according to FIG. 6 is as permeable ger, porous body formed through which this occurs when walking displaced fluid is pushed through.
• the devices described for generating heat are very simple in structure and also in the mode of operation and allow heat in one without an additional energy source To produce footwear, for this only those when walking alternating compressive forces exerted on the sole l be used. This gives a simple and reliable one Execution, which is either in the sole of a shoe, against if necessary exchangeable, or in an insole can be built. It is easily possible to adjust the thickness to keep the device relatively small, so that the sole does not become significantly thicker than a sole usual kind.
• the sole l in different parts len also designed differently than as shown in the figures can be det. So the partial cavities ll, l2 and l3, l4 have any suitable shape. In the further it can be advantageous in the embodiment according to Fig. 2 the partial cavities l3, l4 through in the longitudinal direction partition walls running along the sole l to subdivide ensure that the fluid when walking in the shoe length direction flows and not across it.
• the throttle elements 10, 20 can also be different than the Shown way to be designed.
