Abstract
Abstract A ski boot comprising an external shell and a rigid sole, a slipper producing at least one cavity between the shell and the foot. The method of adjustment consists in filling the cavity with a moldable mixture of products kept in a viscous or paste-like state by means of at least one volatile product, and then eliminating at least one of the volatile products by causing it to pass into a gaseous phase until the mixture of products hardens. The invention has the particular advantage of making it possible to adjust the ski boot to a skier's foot without risk of compressing it in a dangerous manner.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
99 words
A method for adjusting a ski boot including an outer shell, a sole and a slipper located inside said shell and providing at least one cavity between said shell and the foot, comprising: placing the foot to which the boot is to be fitted in the slipper, filling the cavity with a mixture of products solved in at least one volatile product, said mixture being in a stable viscous state; and eliminating the at least one volatile product by causing said volatile product to escape at the atmosphere into a gaseous phase until hardening of the mixture of products.
Claim 2
Independent Claim
99 words
A method for adjusting a ski boot including an outer shell, a sole and a slipper located inside said shell and providing at least one cavity between said shell and the foot, comprising: placing the foot to which the boot is to be fitted in the slipper, filling the cavity with a mixture of products solved in at least one volatile product, said mixture being in a stable viscous state; and eliminating the at least one volatile product by causing said volatile product to escape at the atmosphere into a gaseous phase until hardening of the mixture of products.
Claim 3
Dependent Claim
39 words
A method according to claim 1, wherein the mixture of viscous products introduced into the cavity consists of: a binder made from at least one of the following products: an elastomeric product, a plastic product; and a volatile product.
Claim 4
Dependent Claim
13 words
A method according to claim 2, wherein the mixture also contains a filler.
Claim 5
Dependent Claim
57 words
A method according to claim 2, wherein the elastomeric product is preferably at least one of the following: a natural rubber, reticulated or not, a butyl, nitrile, or chlorinated rubber, a polyisobutylene, an ethylene/propylene rubber, a styrene-butadiene or styrene-isoprene copolymer, a latex, a polyurethane, a silicone, an isobutylene/isopropylene copolymer, a thiokol, a polystyrene or a polystyrene copolymer.
Claim 6
Dependent Claim
32 words
A method according to claim 1, wherein the plastic product is preferably at least one of the following: a polyamide, a polyurethane, an acrylic, a cellulosic, a glycerophthalic, epoxy, or vinyl product.
Claim 7
Dependent Claim
26 words
A method according to claim 3, wherein the filler is made up of resiliently compressible materials such as: polyurethane-foam scrap, rubber powder, polyethylene foam, cork powder.
Claim 8
Dependent Claim
26 words
A method according to claim 2, wherein the filler is made up of incompressible materials, such as wood dust, carbonate of lime, slate powder, polystyrene balls.
Claim 9
Dependent Claim
20 words
A method according to claim 6, wherein the filler is of a grain size ranging between 0.1 and 30 mm.
Claim 10
Dependent Claim
16 words
A method according to claim 1, wherein the volatile product is a solvent of the binder.
Claim 11
Dependent Claim
31 words
A method according to claim 1, wherein the volatile product is preferably at least one of the following organic solvents: aliphatic, aromatic, ketonic, halogenated, with an ether, ester or alcohol function.
Claim 12
Dependent Claim
17 words
A method according to claim 9, wherein the boiling point of the solvent is below 150° C.
Claim 13
Dependent Claim
40 words
A method according to claim 1, wherein, when polystyrene or a polystyrene copolymer is used, the solvent used is a solvent capable of passing into a gaseous phase under close-to-normal pressure and/or temperature conditions (760 mm Hg and 20°-25° C.).
Claim 14
Dependent Claim
16 words
A method according to claim 12, wherein the polystyrene or copolymer is expanded before being dissolved.
Claim 15
Dependent Claim
21 words
A method according to claim 13, wherein the vapor pressure of the solvent is above 0.5 kg/cm 2 at 20° C.
Claim 16
Dependent Claim
13 words
A method according to claim 14, wherein the solvent is a chlorofluorinated hydrocarbon.
Claim 17
Dependent Claim
12 words
A method according to claim 15, wherein the chlorofluorinated hydrocarbon is dichlorofluoromethane.
Claim 18
Dependent Claim
12 words
A method according to claim 15, wherein the chlorofluorinated hydrocarbon is trichlorofluoromethane.
Claim 19
Dependent Claim
25 words
A method according to claim 12, wherein a surfactant, more particularly a silicone oil, is added to the mixture of polystyrene, or copolymer, and solvent.
Claim 20
Dependent Claim
23 words
A method according to claim 1, wherein the mixture is injected under pressure into the cavity located between the foot and the shell.
Claim 21
Dependent Claim
17 words
A method according to claim 19, wherein the volatile product is in a liquid state under pressure.
Claim 22
Dependent Claim
25 words
A method according to claim 1, wherein the cavity located between the foot and the shell is defined by an envelope porous to the solvents.
Claim 23
Dependent Claim
46 words
A method according to claim 1, wherein the mixture is contained in a sealed envelope placed in the boot at the time of manufacture thereof, said envelope being opened, in at least one place, at the time of use, to allow the volatile product to escape.
Claim 24
Dependent Claim
40 words
A method according to claim 12, wherein the mixture is held in an aerosol container by means of which it is projected into the cavity, the solvent being subsequently released from said cavity until the product hardens into a foam.
Claim 25
Dependent Claim
19 words
A method according to claim 1, wherein the mixture located in the boot is heated to evaporate the solvent.
Claim 26
Dependent Claim
23 words
A method according to claim 1, wherein the boot is placed in an enclosure under a vacuum, to assist in evaporating the solvent.
Claim 27
Dependent Claim
32 words
A method according to claim 1, wherein the mixture of viscous products comprises, in addition, a nonevaporable solvent intended to keep the mixture relatively plastic after the volatile product has been eliminated.
