Abstract

A double sided nylon sandwich mesh fabric zipper and slider assembly includes coil strips being left handed and right handed plastic coils each having a center cord and a series of interlocking teeth, each tooth having a tooth head and a tooth body so configured that the tooth heads are respectively interlockable with the tooth heads of the teeth of the coil strips at the other zipper tape. The slider has C-shaped guide grooves to guide locking and unlocking positions horizontal movement of the teeth of the upper and lower coil strips, and a balance guide block configured to match with the configuration of the tooth heads, facilitating accurate alignment between the left and right teeth of the upper and lower coil strips and assuring smooth engagement and disengagement of the interlocking teeth.

Dependent claims

A double sided nylon sandwich mesh fabric zipper and slider assembly comprising a double sided nylon sandwich mesh fabric zipper and a slider, said double sided nylon sandwich mesh fabric zipper comprising opposing left and right zipper tapes and upper and lower coil strips respectively stitched to opposing top and bottom sides of each of said two opposing left and right zipper tapes, wherein:

said upper and lower coil strips are left handed and right handed plastic coils, each comprising a center cord and a series of interlocking teeth, each tooth of said series of interlocking teeth comprising a tooth head and a tooth body, said tooth head and said tooth body being so configured that the tooth heads of said series of interlocking teeth of said upper and lower coil strips at one of said two opposing left and right zipper tapes are respectively interlockable with the tooth heads of the series of interlocking teeth of said upper and lower coil strips at the other of said two opposing left and right zipper tapes, said center cord being compressed into an elliptical columnar shape and having one side edge thereof kept in contact with the tooth heads of said series of interlocking teeth;
said slider comprises a top guard plate, a bottom guard plate, a central partition plate connected between said top guard plate and said bottom guard plate, said top guard plate comprising a top wall, two opposing sidewalls, an upper chamber surrounded by the top wall and two opposing sidewalls of said top guard plate and two C-shaped guide grooves bilaterally formed in said upper chamber and configured to fit the configuration of said series of interlocking teeth of said upper and lower coil strips, said bottom guard plate comprising a bottom wall, two opposing sidewalls, a lower chamber surrounded by the bottom wall and two opposing sidewalls of said bottom guard plate and two C-shaped guide grooves bilaterally formed in said lower chamber and configured to fit the configuration of said series of interlocking teeth of said upper and lower coil strips.

said upper and lower coil strips are left handed and right handed plastic coils, each comprising a center cord and a series of interlocking teeth, each tooth of said series of interlocking teeth comprising a tooth head and a tooth body, said tooth head and said tooth body being so configured that the tooth heads of said series of interlocking teeth of said upper and lower coil strips at one of said two opposing left and right zipper tapes are respectively interlockable with the tooth heads of the series of interlocking teeth of said upper and lower coil strips at the other of said two opposing left and right zipper tapes, said tooth body having a neck portion compressed and deformed into a depressed surface area and two expanded flanges at two opposite lateral sides of said depressed surface area for enhancing engagement tightness between the mating tooth heads;
said slider comprises a top guard plate, a bottom guard plate, a central partition plate connected between said top guard plate and said bottom guard plate, said top guard plate comprising a top wall, two opposing sidewalls, an upper chamber surrounded by the top wall and two opposing sidewalls of said top guard plate and two C-shaped guide grooves bilaterally formed in said upper chamber and configured to fit the configuration of said series of interlocking teeth of said upper and lower coil strips, said bottom guard plate comprising a bottom wall, two opposing sidewalls, a lower chamber surrounded by the bottom wall and two opposing sidewalls of said bottom guard plate and two C-shaped guide grooves bilaterally formed in said lower chamber and configured to fit the configuration of said series of interlocking teeth of said upper and lower coil strips.
