Definitions

  • the present invention relates to Auto lock slider, made of plastic, to be used in slide fasteners (Zippers) of all types, Plastic Moulded/Extruded, Ladder, Coil and Metal in all designations and operating arrangements.
  • Slide fasteners also called zippers are very commonly known.
  • the zipper consists of two stringers with a row of teeth specially shaped and made of metal, plastic or polyester coil.
  • a slider operated by hand, moves along the length of the stringers clasping together the rows of teeth.
  • the slider is an essential component of the slide fastener.
  • an auto lock slider is provided with a locking mechanism that automatically locks the slider to the slide fastener chain at a desired position.
  • FIG. 1 illustrates a conventional slider.
  • the various components of the slider are a cap assembly 3 , a locking pin 4 , a puller 5 and a slider body 6 .
  • the cap assembly 3 further comprises a cap 1 and a leaf spring 2 .
  • the leaf spring 2 is cut into an appropriate shape and fixed inside the cap 1 .
  • the locking pin 4 is made from a metallic strip preferably steel or copper alloy with protective plating.
  • the body 6 and the puller 5 are manufactured by process such as injection moulding.
  • the manufacturing process of the conventional five-piece slider involves separate processes such as cutting, stamping or injection moulding for each component.
  • all these components, such as the body 6 , puller 5 , locking pin 4 and cap assembly 3 are assembled manually or automatically. A series of steps are involved in attaching the components to one another making the manufacturing process very tedious and time consuming.
  • the conventional plastic Auto lock sliders as described and also similar others existing sliders suffer from a number of limitations like poor puller strength, reduced reliability due to multiple parts and expensive process of manufacture.
  • the leaf spring 2 used in the conventional configuration has to be accurately cut and positioned inside the cap 1 to ensure proper operation of locking mechanism. More importantly, while painting such a slider, the paint that gets deposited in the cavity of the cap 1 and leaf spring 2 often makes the locking mechanism ineffective and unreliable.
  • the basic object of the present invention is thus directed to providing a plastic Auto lock slider for slide fasteners that would on one hand be simple in construction and on the other hand would provide a safe with desired puller strength and user friendly slider with secured lock arresting the sliding motion in a secured manner and provide for desired reliability of performance of the slider assembly.
  • Another object of the present invention is directed to an Auto lock plastic slider which can be adapted for manufacture of sliders for slide fasteners of wide range/combination of materials for its different components and for use with various slide fasteners made of different materials.
  • a still further object of the present invention is directed to said Auto lock plastic slider which would be simple and cost effective to assemble/manufacture with minimum skill and tools and importantly involving minimum number of operative components with desired puller strength and reliable performance.
  • Yet further object of the present invention is directed to an Auto lock plastic slider of simple configuration directed to achieve simplicity in construction including the body and the puller adapted for injection moulding integrally or moulded separately or by insert moulding depending upon the material chosen for puller and body with a selective locking member of resilient material of desired shape, to facilitate the reliable and fail free locking and/or unlocking of the slide fastener during use.
  • a still further object of the present invention is directed to said auto lock plastic slider adapted with user friendly and safe operation for slide fasteners such that the locking and unlocking action could be performed involving minimum of operative components in a selective configuration without any failure in achieving such desired functions even in the presence of paints or the like.
  • an auto lock plastic slider for slide fasteners comprising:
  • a slider body having slots formed therein; a puller means provided with a cam like arrangement; a resilient locking member, and a slide fastener chain said slider body adapted such that once assembled through the slot at one end, said resilient locking member get arrested with respect to said slider body, said resilient locking member is adapted to cooperate with said cam provision in said puller means so as to effect engaging and disengaging of the other end of said resilient locking member with respect to said slide fastener chain through a slot in said slider body to thereby lock or unlock said slide fastener.
  • an auto lock plastic slider for slide fasteners comprising: an integrally formed slider body having slots formed therein and a puller means provided with a cam like arrangement; and a resilient locking member, said slider body adapted such that once assembled through a slot at one end said resilient locking member gets arrested with respect to said slider body, said resilient locking member adapted to cooperate with said cam provision in said puller means such as to effect said engaging and disengaging of the other end of said resilient locking member with respect to said slide fastener through a slot in said slider body to thereby lock or unlock said slide fastener.
  • a slot at the rear of the slider body is adapted to secure said one end of the resilient locking member with respect to the slider body and a slot on the top of the slider body adapted to allow said other end of the resilient locking member to engage or disengage with respect to said slide fastener chain within the slider body.
  • said resilient locking member at said end region is adapted to get secured with respect to said slider body and is provided with a suitably shaped end portion which gets arrested within a correspondingly adapted slotted region at the rear of said slider body and said other end of the resilient locking member is adapted to facilitate said engaging and disengaging of the resilient locking member with the slide fastener chain.
  • said puller means comprise a cam like protrusion adapted to enable said resilient locking member to engage or disengage with the slide fastener chain to ensure locking and unlocking of the slide fastener.
  • the resilient locking member is configured to match the profile of the body and puller and its assembly with respect to the slider body slots. Also, the disposition of puller position provides for the locking and unlocking with the selective disposition of puller on top side of slider providing for the unlocking.
  • the slider body and the puller in the auto lock slider of the invention can be obtained by integral injection moulding or insert moulding selectively based on the material for the puller and the slider body.
  • the resilient locking member used in the auto lock plastic slider for slide fasteners of the invention is made of elastic material.
  • the bridge of the puller is supported by two bails in the body for desired puller strength.
  • the auto lock plastic slider for slide fasteners of the present invention comprises a plastic/synthetic material slider preferably suited for painting applications.
  • the slider body and the puller are selectively made of same or different plastic and/or metal and/or any composite material.
  • the auto lock plastic slider for slide fasteners of the invention is thus adapted to comprise selectively plastic moulded slide fastener, Ladder type slide fastener, Polyester coil slide fastener and metal type slide fastener.
  • FIG. 1 illustrates the design of an existing slider which consists of body 6 , puller 5 , cap 1 , leaf spring 2 and lock pin 4 .
  • FIG. 2 illustrates a slider 10 in accordance with one embodiment of the present invention.
  • the slider 10 comprises a slider body 7 , a puller means 8 moulded integrally to the slider body 7 and a resilient locking member 9 .
  • FIG. 3 illustrates the resilient locking member 9 of the previous embodiment fitted into the slider body 7 through the puller means 8 .
  • FIG. 4 illustrates the unlocking and locking action of the resilient locking member 9 .
  • FIG. 5 illustrates the slider 10 in accordance with another embodiment of the present invention wherein a slider body 12 and a puller means 13 are moulded separately and then assembled with a resilient locking member 14 .
