Definitions
- the subject of the invention is a comfort slipper for ski boot comprising a viscous material fluid held between two layers of flexible materials and restraint.
- Such a shoe is known from US Pat. No. 4,255,202. parts of this slipper for surrounding the ankle and the malleolar region form a pocket containing a viscous viscous material.
- a slipper is intended to be used in a rigid shoe shell. then the shoe of such a shoe, the pocket is deformed by the creep of the viscous material so as to adapt to the morphology of the foot.
- Such a slipper therefore has the advantage of simultaneously good foot hold and foot comfort in the shoe.
- the pocket In order to fill the space between the foot and the hull, the pocket must be relatively thick. By the way, to marry the shape of the foot, the creep of the viscous material is important.
- Such a foam has, in addition to the disadvantage of previously cited slipper, that of hardening in aging.
- a shoe having an inner lining consisting of a sealed envelope defining a plurality of chambers communicating with each other by narrow channels, filled a fluid having a certain viscosity.
- this envelope is subjected to non-uniform pressure foot, the viscous fluid escapes from the chambers subjected to the strongest pressure to pass through rooms less solicited. In this case, too, the envelope does not return to its original form without pressure is exerted on the envelope.
- the present invention aims to achieve a slipper presenting immediately and so repetitive feeling of comfort when putting on.
- the liner according to the invention is characterized in that the flowable viscous material is content and divided into small elemental volumes in an elastically compressible material.
- each of these small volumes deforms very quickly, while the material elastically compressible immediately adapts to this deformation, so that the shoe fits almost instantly to the morphology of the foot, giving this sought-after impression of immediate comfort.
- the viscous material After heaving, the viscous material resumes its initial shape under the thrust of the material elastically compressible surrounding it at least partially. Again, given the small volumes of viscous material, these volumes resume completely their initial shape and this relatively quickly.
- the user finds exactly the same impression of comfort as during the first boot. This will also be the case if the shoe is paved by another person.
- the viscous material is preferably contained in alveoli and the dimensions of these cells are, of preferably, of the order of magnitude of the thickness of the slipper.
- the elastically compressible material in which are formed the cells is, advantageously, a layer intermediate foam.
- the alveoli cross the intermediate layer of foam and are closed on one side by a layer of moss firm constituting the outer face of the slipper and, the other side, by a layer of soft foam, constituting the inner face of the liner.
- the appended drawing represents, by way of example, a slipper structure according to the invention.
- Figure 1 shows a sectional view
- Figure 2 shows a piece of the slipper seen from side of the inner foam, this foam partially removed.
- the structure shown comprises a layer 1 of firm mousse constituting the outer side of the slipper, an intermediate layer 2 made of foam of medium firmness having good elasticity and a layer of foam 3, soft and supple, constituting the inner side of the slipper.
- the foam 3 is a so-called comfort foam.
- the intermediate layer of foam 2 is perforated regularly circular holes forming cells cylindrical 4.
- the thickness of the intermediate layer 2 is about 5 mm.
- the diameter of the cells 4 is about 8 mm and the distance between the cells is about 3 mm.
- the total thickness of the slipper is about 10 mm.
- the dimension of the cells 4 is therefore the order of magnitude of the thickness of the shoe.
- the 4 cells are closed on one side by the foam 1 and, on the other side, by the foam 3.
- These cells 4 are filled with a flowable viscous material 5, by example a gel, such as polyisobutene generally charged, in particular microspheres or powder cork.
- the thickness of the intermediate foam layer can be constant or variable over the extent of the slipper.
- the viscous material When donning, the viscous material is deformed relatively slowly, by creep, to adapt to the morphology of the foot, this deformation being fast enough to give an impression of comfort.
- the viscous material behaves as a rigid material during rapid changes in pressure, as is the case with skiing when taking square or edge change, thus ensuring a precise driving of the ski.
- the cells 4 take again gradually their initial shape due to the elasticity of the moss surrounding them, putting the slipper in its initial configuration at each boot.
- the cells could also be formed in one of the layers of foam 1 or 3, that is to say in part of the thickness of the foam. In this case, he there is therefore no intermediate layer.
- the foam intermediate can be molded or thermoformed from way to present an anatomical shape, and then perforated to form cells.
