Description
- 1. Field of the Invention
- The present invention relates to zipper technology and more particularly, to a zipper slide for double-layer nylon zipper, which greatly improves sliding mobility, reducing zipper sewing seam and teeth wear and prolonging zipper slide lifespan.
- 2. Description of the Related Art
- The basic functional design of a zipper slide derives from rotating engagement between gears. The left series of teeth and right series of teeth of a zip fastener are regarded as two equal length flexible tooth bar. A zipper slide is movable by a pull tab to interlock or separate left and right series of teeth. In order to enhance protection and to prevent the occurrence of zipper split, double layer zippers are created. U.S. Pat. No. D651,129, issued to the present inventor, discloses a double layer coil zipper slider for use in a double layer zipper. A zipper slider for double layer zipper increases the distance between the opposing top and bottom slide body blocks and provides a tongue-shaped guide plate at the center block between the opposing top and bottom slide body blocks for separating the upper and lower fabric tapes of the double-layer nylon zipper. According to conventional designs, the top and bottom slide body blocks are identical in shape; the top slide body block has a crown located at a top side thereof for securing a pull tab. The upper and lower layers of left and right series of interlocking teeth of a double layer zipper are fastened together with stitches.
- Further, the upper layer of left and right series of interlocking teeth and the lower layer of left and right series of interlocking teeth are differently curbed when the zipper slider is cornering, causing the interlocking teeth of the lower layer of left and right series of interlocking teeth to be abnormally squeezed. Because the upper and lower layers of left and right series of interlocking teeth are moved in the same chamber in the zipper slider between the opposing top and bottom slide body blocks and differently curved when cornering, a large friction resistance can occur, and thus the stitches of the zipper can be worn out quickly, and the top and bottom slide body blocks, the center block and/or the pull tab can be easily permanently deformed or damaged.
- The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a zipper slide for double-layer nylon zipper, which has the characteristics of good security performance, long lifespan and high linking strength, and can easily be opened and closed when cornering.

FIGS. 1-9 , azipper slide 60 for double-layer nylon zipper in accordance with the present invention is shown. As illustrated, thezipper slide 60 comprises a topslide body block 1, a bottomslide body block 2, twoupper guard flanges 3 respectively downwardly extended from two opposite lateral sides of the topslide body block 1, twolower guard flanges 4 respectively upwardly extended from two opposite lateral sides of the bottomslide body block 2, acenter block 5 connected between the topslide body block 1 and the bottomslide body block 2, a tongue-shaped guide plate 7 forwardly extended from a front middle part of thecenter block 5 and equally spaced between the topslide body block 1 and the bottomslide body block 2 for separating the upper and lower fabric tapes of the double-layer nylon zipper 6, twoupper guide grooves 9 located on a rear part of a bottom surface of the topslide body block 1 at two opposite lateral sides relative to thecenter block 5, and twolower guide grooves 10 located on a rear part of a top surface of the bottomslide body block 2 at two opposite lateral sides relative to thecenter block 5. The topslide body block 1 and the bottomslide body block 2 have respective front sides thereof kept in vertical alignment. The bottomslide body block 2 has its rear side retracted relative to the rear side of the topslide body block 2. The retraction distance is about equal to the thickness S of one layer of zipper chain tape of the double-layer nylon zipper 6 (seeFIG. 3 ,FIG. 7 andFIG. 10 ). Thezipper slide 60 further comprises aconnection part 8 connected between the rear side of the bottomslide body block 2 and a bottom side of thecenter block 5 and kept in flush with the bottomslide body block 2 to reinforce the tensile strength of the topslide body block 1 and the bottomslide body block 2. Further, theupper guard flanges 3 are relatively longer than thelower guard flanges 4 so that theupper guard flanges 3 are kept relatively closer to thecenter block 5 than thelower guard flanges 4 to shift the fulcrum G forward (seeFIG. 12 ), enabling each of the integrated opposing left and right series of interlockingteeth 61 to face toward the fulcrum G and the center block 5 (tooth engagement position H) when it is opened to the extent. As the fulcrum G has been shifted forward, each of the left and right series of interlockingteeth 61 can quickly return to the normal tooth pitch b when reached the tooth engagement position H. In the prior art design shown inFIG. 13 , the length of theupper guard flanges 3′ of thezipper slide 60′ remains the same as the lower guard flanges, and therefore this design cannot shift the fulcrum G′ forward. In consequence, each of the left and right series of interlockingteeth 61′ can quickly return to the normal tooth pitch when reached the tooth engagement position, leading to engagement failure or disengagement. In comparison to the prior art design, the tooth pitch b (seeFIG. 12 ) of the present invention is smaller than the tooth pitch a (seeFIG. 13 ) of the prior art design, and therefore, the invention enhances tooth engagement stability, preventing accidental sliding or twisting of the zipper slide relative to the double-layer nylon zipper 6. Further, the design of the upper guide grooves 9 at the topslide body block 1 around thecenter block 5 and thelower guide grooves 10 at the bottomslide body block 2 around thecenter block 5 facilitates coupling thezipper slide 60 to the double-layer nylon zipper 6. Further, the width E of the entrance of each of theupper guide grooves 9 andlower guide grooves 10 is equal to the width of the interlocking teeth; the depth of theupper guide grooves 9 andlower guide grooves 10 is in the range about ⅛˜¼ of the thickness S of the interlocking teeth (i.e., ⅛ S˜¼ S). - Subject to the retracted design of the rear side of the bottom
slide body block 2 relative to the topslide body block 1, there is sufficient space for allowing the inner layer of the double-layer nylon zipper 6 to be smoothly curved when the zipper slide is cornering, reducing zipper friction resistance and prolonging the zipper lifespan. - Further, the design of the
connection part 8 at the rear side of the bottomslide body block 2 around thecenter block 5 greatly enhances the connection strength between the bottomslide body block 2 around thecenter block 5 and the tensile strength between the topslide body block 1 and the bottomslide body block 2. Further, when moving thezipper slide 60 to close or open the left and right series of interlockingteeth 61 of the double-layer nylon zipper 6, the left and right series of interlockingteeth 61 are positively supported on theconnection part 8 and kept within a limited angle F (seeFIG. 11 ), and thus, the left and right series of interlockingteeth 61 can be smoothly and positively guided by thezipper slide 60 into an interlocked status. - In conclusion, the zipper slide 60 for double-layer nylon zipper in accordance with the present invention is characterized by the retracted design of the rear side of the bottom
slide body block 2 relative to the topslide body block 1 to provide sufficient space for allowing the inner layer of the double-layer nylon zipper 6 to be smoothly curved when the zipper slide is cornering, reducing zipper friction resistance and prolonging the zipper lifespan; the design of theconnection part 8 at the rear side of the bottomslide body block 2 around thecenter block 5 greatly enhances the connection strength between the bottomslide body block 2 around thecenter block 5 and the tensile strength between the topslide body block 1 and the bottomslide body block 2, enabling the left and right series of interlockingteeth 61 to be positively supported on theconnection part 8 so that the left and right series of interlockingteeth 61 can be smoothly and positively guided by thezipper slide 60 into an interlocked status when thezipper slide 60 is cornering. - While only few embodiment of the present invention have been shown and described, it will be understood that various modifications and changes could be made thereunto without departing from the spirit and scope of the invention disclosed.
