Abstract
Embodiments herein provide modified slider bodies with one or more features such as an elongated spring cap, a protrusion on the bottom plate and/or plate coupler of the slider body, and/or vertically offset side rails. These features may minimize introduction of loose fabric, such as the lining of a lined garment, into the tape slot of the slider body, thereby help reduce jamming of the slider body during operation of the slide fastener.
Claims5
A slider body comprising:
- a top plate having downwardly projecting top rails, the top plate coupled to a slider cap;
- a bottom plate having upwardly projecting bottom rails;
- a plate coupler coupled to the top plate and the bottom plate;
- a joining section disposed between the top plate and the bottom plate to accommodate a zipper tape, the joining section having a length, and the slider cap having a length equal to or greater than 150% of the length of the joining section and defining an opening between the slider cap and the top plate that extends across a center of mass of the slider body along a first axis;
- a pull tab coupled to the slider cap to move the slider body along the first axis to open or close a slide fastener, wherein the pull tab is movable within the opening along the first axis;
- and
- a protrusion projecting downward from the bottom plate to push an inner layer of material, which is coupled to the zipper tape, away from the joining section, wherein the protrusion has a height from the bottom plate that is substantially the same along an entire length of the protrusion, and wherein an outer surface of the protrusion forms a continuous structure with the bottom plate but does not form a hole or passage through the protrusion.

- a bottom plate having upwardly projecting bottom rails;
- a plate coupler coupled to the top plate and the bottom plate;
- a joining section disposed between the top plate and the bottom plate to accommodate a zipper tape;
- and
- a protrusion projecting downward from the bottom plate to push an inner layer of material, which is coupled to the zipper tape, away from the joining section, said protrusion having a leading edge that projects from an anterior portion of the slider body and a trailing edge that projects from a posterior portion of the slider body, wherein the leading and trailing edges are oriented orthogonally with respect to an upper surface of the bottom plate, wherein the protrusion has a height from the bottom plate that is substantially the same along an entire length of the protrusion, and wherein an outer surface of the protrusion forms a continuous structure with the bottom plate but does not form a hole or passage through the protrusion.
