Definitions
- the present invention relates to a zipper allowing the operation of the cursor of a zipper as well as the zipper equipped with such a zipper, and intended in particular for the closure of shoes, clothing, portable bags, etc.
- the zipper and the cursor associated therewith can be of any usual type.
- this slider 2 has a trigger guard 3 to which the pull-out 1 is subject allowing the slider 2 to be operated; the base of this slider cooperates in a conventional manner with the slides of the closure 4.
- the zipper pulls are traditionally made of a metallic material; due to the significant efforts often exerted by the user, they must indeed be very enduring to impact and to torsion.
- these metallic materials are rigid materials, therefore practically not liable to deformation, torsion or bending, all of which promote tearing of the trigger guard or deformation of the critical parts of the pull tab, in particular when it these are zippers arranged in places that are not easily accessible to the user: snow sports shoes for example, where gripping with gloves is not easy.
- the object of the present invention is to determine, among the thermoplastic synthetic polymers, easier to work than thermosets, those which may be suitable for the production of zippers for zippers.
- the material must also have essential characteristics of elongation, flexibility, toughness, endurance, impact resistance and resistance to traction and torsion. - these characteristics must be kept at low temperature, an essential condition in particular in the case of articles intended to be used under the severe temperature conditions of snow sports.
- the materials selected must not exhibit excessive sensitivity to ultraviolet radiation.
- thermoplastic polymers elastomers
- Thermoplastic elastomers are materials which meet common physical characteristics, among which there may be mentioned low rigidity, very high elongation at break and in most cases a total absence of elasticity threshold corresponding to an extremely amorphous product.
- thermoplastic block copolymers are in fact copolymers composed of two phases, one amorphous, the other crystalline, arranged in blocks along the molecular chains.
- the crystalline zones regroup in domains uniformly distributed in the amorphous zones.
- thermoplastic zones constitute reversible physical crosslinking nodes which give these materials behavior similar to that of conventional elastomers after vulcanization.
- US-C-4,949,434 has proposed making pull tabs for operating the slider of a zipper in a synthetic material having elasticity properties, such as a synthetic elastomer and in particular a polyester elastomer.
- the amorphous phase of these copolymers is of the ester or ether type while the rigid phase is of the polybutylene terephthalate type.
- polyester or polyether-block-ester elastomers are extremely sensitive to ultraviolet radiation: although their yellowing is limited, their mechanical characteristics drop sharply during prolonged exposure; they therefore impose anti-U V protection using appropriate additives.
- polyether block urethane copolymers it has also been thought to use polyether block urethane copolymers.
- the amorphous block consists of the reaction product of a long chain polyol with an isocyanate, while the rigid block results from the action of an isocyanate with a very short chain glycol.
- This type of copolymer owes its reinforcing character to the hydrogen bonds located between the chains of the polymer.
- copolymers have excellent tensile strength as well as abrasion wear, but there is a very significant yellowing under the action of ultraviolet light as well as pronounced stiffening at low temperature for a large number of types of these. polymers.
- the amorphous block consists of a very amorphous ether phase which brings the flexibility properties.
- the rigid sequence is made from sections of chains of the Polyamide 6 or Polyamide 12 type.
- the pull tab allowing the operation of the slider of a zipper according to the invention is therefore characterized in that this elastomer is chosen from polyether amide block copolymers.
- copolymers are specially easy to color which allows the production of drawbars in all the fashion colors and their glossy surface appearance is very flattering.
- the pull tab made of amide block copolymers according to the invention is specially adapted to the types of pull tabs described in Fr-A-89 17550 filed on 29.12.89 by the applicant.
- This zipper can, whatever the position of the cursor along the slide, be immobilized relative to the cursor itself in at least one stable position, in particular for erasing, by plating on the slide.
- the material used in the present invention allows one can play on the elasticity of said material to reduce to an almost negligible degree the transmission of the torque and bending forces on the trigger guard, and simultaneously, give the pull tab a more large and more generally of larger dimensions, in particular in length by increasing both its lifespan and the ease of gripping, even with a gloved hand.
- the present invention cannot of course be limited to this single type of zipper pullers and can find applications in the various existing models.
