Definitions

• the present invention relates to zippers fitted to footwear or protective clothing, including sports shoes and in particular shoes for the practice of cross-country skiing.
• the shoes illustrated in these documents have at least one zipper, associated or not with a lacing device, disposed on the upper front part of the upper of said shoes.
• These zippers generally consist of notches, spirals, etc. coming to mesh successively with each other to ensure the butting of the walls of the shoe, are oriented generally along the longitudinal axis of the shoe or parallel to it.
• the closure surrounds the upper front part of the upper and retains it at the lower part of the upper.
• the present invention aims to eliminate the drawbacks due to the flexing of the vamp during the unwinding of the foot which have been mentioned with these zippers by eliminating, on the one hand, the risks of local deterioration of the slide at the level of the parts presenting in relief, and on the other hand guaranteeing an optimum seal, both to dirt, to snow and water.
• the present invention relates to a zipper for footwear or protective clothing, the slide of which consists of two rack support ribbons and an operating slider is mounted on a part of said article or clothing, the two edges of which are at approximate and is characterized in that the racks are connected to their respective support ribbons so that they are located in relief on the single side of said ribbons intended to be turned towards the inside of said footwear or garment
• a sealing layer which can cover at least the means of assembling the rack to the support, for s 'extend if necessary at the location of the rack relative to the support of said rack.
• this e ⁇ duction of a sealing layer is preferably applied to the side of the support intended to be turned towards the outside of the shoe.
• Figures 1 and 2 show in detail, part of a zipper according to the invention, Figure 1 being a sectional view along ll-ll of Figure 2 which illustrating, in plan view, the end of the slide with cursor.
• Figure 3 shows, in an enlarged sectional view, a slide according to the invention provided with an eta ⁇ chéification film in the uncoupled position.
• Figure 4 shows the slide according to Figure 3 in the closed position.
• Figure 5 shows a zipper according to the invention mounted on the upper of a cross-country ski boot.
• FIGS 6 and 7 illustrate another method of mounting the closure of the slide always according to the invention.
• the zipper 1 is of the type whose racks 11 extend on one side of their respective support tape 13 and is characterized in that it comprises a cursor 16 whose zipper 17 is arranged on the side opposite to the connection tunnel 18 of said racks 11.
• the notches 12 (or spirals as is the case in this construction method) are fixed and applied to one side of each support strip 13 by means of seams or staples 14, at a certain distance from the edge 15 of said ribbon; this distance is determined as a function of the nesting depth of the notches or spirals 12 so that the edges 15 of the strips 13 of the zipper 1 are contiguous and leave visible only a dividing line 15 'when the racks 1 1 are fitted.
• the racks 11 are fixed at a distance substantially less than that corresponding to the nesting depth of the notches or spirals 12.
• the edges 15 of the ribbons 13 are applied with a certain pressure against each other or overlap which, in all cases, improves the sealing of the zipper 1.
• This enductio n sealing 19 will complete the mechanical sealing of the zipper because it will be applied without any obstacle on the flat face 13 ′ of the support strip 13 of the rack intended to be turned towards the outside of the shoe, or even a protective element for example.
• the waterproof coating 19 carried out on this exposed surface 13 ′ of the support tapes 13 will cover and seal the seams or staples 14 without the slightest gap remaining capable of causing certain permeability to water, dirt, etc., and will therefore guarantee an absolute seal with respect to the outside of the slide.
• waterproof layer 19 can also be applied so as not to overflow with respect to the support tape 13.
• the zipper 1 is arranged, in a conventional manner, on the front part of the upper 2 substantially in the longitudinal axis of the shoe 10 and extends approximately to the zone 3 corresponding to that of the metatarsophalangeal joint of the foot (not shown).
• the zipper 1 has support ribbons 13 which are only turned towards the outside of the shoe, while its racks are directed towards the inside of the upper 2, the dividing line 15 'of the edges 15 of said ribbons also appears on the outside of the shoe, it is obvious that the seams or staples 14 are only visible if the ribbons 13 have not been coated with an opaque waterproof coating or colored as mentioned above in the description of FIG. 3.
• the zipper 1 according to the invention can also be arranged in other ways on shoe uppers, in particular to use the advantages resulting from its relative flexibility in the longitudinal direction of its mounting.
• the slide 1 of the closure according to the invention is arranged on the upper 2 in extending in a direction inclined with respect to the longitudinal mean axis of the shoe.
• the problems associated with repeated longitudinal deformations of the slide 1 due to the unwinding of the foot are largely eliminated around instantaneous axes of rotation perpendicular to the longitudinal axis of the shoe.
• the slide 1 runs over the upper 2 of the zone 3 corresponding substantially to that of the metatarsophalangeal joint of the foot towards the rear and the external flank of the instep in the direction of the zone. 6 of the external malleolus of the foot.
• the part of the slide 1 which runs on the side of the instep is not subjected to significant bending or deformation forces in this area of the foot, the slide is all the more effective in ensuring good holding of the foot in the shoe, without the comfort being affected.
• the upper 2 of such a shoe may, at least in the upper covering zone of the foot, be provided in an extensible and / or elastic material which may be waterproof. Also, at least one of the parts of the upper 2 adjacent to the support ribbons 13 of the zipper 1, or even at least one of the support ribbons 13, can be obtained from an extensible material; in this way the upper 2 will be applied tightly on the foot whatever the volume of the latter.
