Magnetic zipper

Abstract

A magnetic zipper includes a pair of mating strands each having a plurality of spaced teeth formed on an inner edge thereof with mating notches formed therebetween. Positioned within each of the notches on both strands is a magnet having a given polarity. Attached to each tooth on both strands is a magnet having a polarity opposite that of the given polarity. The size or geometric configuration of the teeth and notches successively vary so that the two strands cannot be inadvertently joined when misaligned. Accordingly, when the teeth on one strand are positioned near or in their designated notches on the other, the zipper strands firmly adhere to close a garment opening. To open the zipper, a garment wearer simply pulls the tenuously-held zipper strands apart.

Claims

1. A magnetic zipper comprising: a first strand having a plurality of spaced teeth on an inner edge with notches therebetween; a second strand adjacent to said first strand, said second strand having a plurality of spaced teeth on an inner edge with notches therebetween, wherein a predetermined number of teeth on said first strand successively vary in dimension, and a predetermined number of notches on said second strand successively vary in dimension so that each of the predetermined number of teeth on said first strand only fit within a designated one of said predetermined notches on said second strand to prevent said first strand and said second strand from being joined in a misaligned orientation; a first magnet positioned within each of the notches on said first strand and said second strand, said first magnet having a predetermined polarity; a second magnet positioned on each of the teeth on said first strand and said second strand, said second magnet having an opposite polarity than said predetermined polarity whereby when said teeth on said second strand are positioned near the notches on said first strand, said first strand and said second strand firmly join; a lip within each of said notches on either of said first strand and said second strand that prevents the teeth from shifting horizontally during use.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a front, plan view of the zipper according to the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(2) A magnetic zipper includes a pair of mating strands 1, each having a plurality of spaced teeth 2 formed on an inner edge thereof with notches 3 formed therebetween. Positioned within each of the notches on both strands is a magnet 5 having a given polarity. Embedded in or attached to each tooth on both strands is a magnet 4 having a polarity opposite that of the magnets within the notches. One of the strands 5 may also include a lip 7 on a rear edge that is positioned within each notch for preventing the teeth from shifting horizontally while a garment is being worn.

(3) A predetermined number of successive teeth and notches on both strands each have a discrete, varying dimension so that the first tooth on one strand can only be joined with a first notch on the opposing strand, the second tooth on one strand can only be joined with the second notch on the other strand, and so on. FIG. 1 depicts multiple sets of five consecutive varying-sized teeth and notches having discrete dimensions a, b, c, d and e. However, the predetermined number of successively varying teeth can be two or more depending upon the size of the zipper and the type of article being joined. Furthermore, the predetermined number can repeatedly cycle between two or more sets, or the predetermined number may simply continue from one end of the strand to the other depending upon the application.

(4) Accordingly, when the teeth on one strand are positioned near or in the mating corresponding notches on the other, the zipper strands firmly adhere to close a garment or other article opening. However, if the user initially misaligns the teeth on one strand with the notches on the other, the successive varying-sized teeth and notches will prevent the strands from clinging until the two strands are properly aligned. To open the zipper, a garment wearer simply pulls the tenuously held zipper strands apart.

(5) The above-described device is not limited to the exact details of construction and enumeration of parts provided herein. For example, though the device has been primarily depicted and described as being designed for clothing, it can be equally incorporated into bags, luggage or any other item having a zipper closure. Moreover, though the teeth and notches have been depicted and described as successively varying in size, they can also vary in shape, geometry or other configuration as long as a given tooth within a series can only fit within a designated notch within a corresponding series on the other strand. Furthermore, the size, shape and materials of construction of the various components can be varied.

(6) Although there has been shown and described the preferred embodiment of the present invention, it will be readily apparent to those skilled in the art that modifications may be made thereto which do not exceed the scope of the appended claims. Therefore, the scope of the invention is only to be limited by the following claims.
