- Zippers are generally classified into closed-end zippers, open-end zippers, double-open-end zippers, closed-end zippers with double ends and double sliders, namely “O” shape zippers. Closed-end zippers are mostly used for trousers plackets, pockets and other parts, while open-end zippers and double-open-end zippers are mostly used for jacket plackets. “O” shape zippers are mostly used for bags and suitcases, but less for clothing.
- Closed-end zippers are often used on bed packs and some beddings, and a gap is always left at zipper top stops of the existing beddings and bed packs, which allows mites and dust to enter and allows fillers to frequently get out of the gap, so that users will feel uncomfortable after long-term use.
- The purpose of the present invention is to provide a sealed zipper top stop with good sealing effect.
- Therefore, a technical solution adopted by the present invention is to provide a sealed zipper top stop, comprising:
- a body, wherein a groove matched with one end of a slider close to the body is arranged at one side of the body close to the slider; and
- two elastic clamping tongues, wherein one end of each of the two elastic clamping tongues is arranged at the bottom of the groove, and the other end extends towards a direction away from the body, and the two elastic clamping tongues are arranged in an inverted splay shape, so that the gap between the two elastic clamping tongues decreases gradually from the end close to the body to the end away from the body;
- wherein both sides of the body and one side on which the two elastic clamping tongues deviate from each other are provided with clamping grooves extending along the lengthwise direction of the zipper.
- In an example of the present invention, each of the two elastic clamping tongues comprises a clamping side, and the clamping sides of the two elastic clamping tongues are arranged oppositely; each of the clamping sides comprises a holding section, a connecting section and a lead-in section, wherein one end of the holding section is connected with the body, one end of the connecting section is connected with the other end of the holding section, and one end of the lead-in section is connected with the other end of the connecting section; a holding space for holding a top tongue of the slider is formed between the two holding sections and the two connecting sections of the two clamping sides, and a lead-in space for guiding the slider is formed between the two lead-in sections of the two clamping sides, and the size of the holding space is larger than that of the lead-in space.
- In an example of the present invention, the holding sections, the connecting sections and the lead-in sections are planar, the two connecting sections are obliquely arranged at the two corresponding holding sections respectively, and ends of the two connecting sections away from the two corresponding holding sections are close to each other.
- In an example of the present invention, each of the elastic clamping tongues further comprises a lead-in side adjacent to the clamping side and a sidestep side opposite to the clamping side, and the width between the sidestep side and the clamping side decreases gradually from the end close to the body to the end away from the body.
- In an example of the present invention, a first arc chamfer is formed between the clamping side and the lead-in side, and/or a second arc chamfer is formed between the lead-in side and the sidestep side.
- In an example of the present invention, the two elastic clamping tongues are provided with guide projections on the upper side and/or the lower side respectively, each of the two guide projections comprises a guide surface, and the guide surfaces of the two guide projections are parallel to each other and extend along the lengthwise direction of the zipper.

- Referring to
FIG. 1 toFIG. 2 , a sealed zipper top stop provided in an example of the present invention comprises abody 1 and twoelastic clamping tongues 2. Agroove 11 matched with one end of a slider close to thebody 1 is arranged at one side of thebody 1 close to the slider. One end of each of the twoelastic clamping tongues 2 is arranged at the bottom of thegroove 11, and the other end extends towards a direction away from thebody 1, and the twoelastic clamping tongues 2 are arranged in an inverted splay shape, so that the gap between the twoelastic clamping tongues 2 decreases gradually from the end close to thebody 1 to the end away from thebody 1. Both sides of thebody 1 and one side on which the twoelastic clamping tongues 2 deviate from each other are provided withclamping grooves 5 extending along the lengthwise direction of the zipper. - In actual use of the sealed zipper top stop, a left tape and a right tape of the zipper pass through the
clamping grooves 5 on both sides of thebody 1 and one side on which the twoelastic clamping tongues 2 deviate from each other respectively, so that the sealed zipper top stop can be pressed and fixed on the left tape and the right tape through theclamping grooves 5; when the slider moves on zipper teeth until the end of the slider close to thebody 1 fits closely with thegroove 11, the twoelastic clamping tongues 2 are inserted into the lead-in inlets on both sides of the top tongue of the slider. The gap between the twoelastic clamping tongues 2 decreases gradually from the end close to thebody 1 to the end away from thebody 1, thus providing a clamping force, making the slider fixed and not easy to loosen. - In this way, the
groove 11 matched with the slider is arranged on one side of thebody 1 close to the slider, so that the slider can fit closely with thebody 1 when moving to thebody 1 without creating a gap, and the sealing effect is good. With a compact structure, the sealed zipper top stop can effectively prevent mites and dust from getting in and out or fillers from overflowing when in use, and is thus very suitable for popularization. The twoelastic clamping tongues 2 arranged in thegroove 11 can be inserted into lead-in inlets on both sides of the top tongue of the slider to clamp and fix the slider, thereby preventing the slider from loosening. - Specifically, in an example, the sealed zipper top stop is a plastic part, so that the two clamping tongues are elastic and can be elastically deformed. The two
elastic clamping tongues 2 can be arranged symmetrically about the centerline of thebody 1. - In the example of the present invention, each of the two
elastic clamping tongues 2 comprises a clamping side 21, and the clamping sides 21 of the twoelastic clamping tongues 2 are arranged oppositely; each of the clamping sides 21 comprises aholding section 211, a connecting section 212 and a lead-insection 213, wherein one end of theholding section 211 is connected with thebody 1, one end of the connecting section 212 is connected with the other end of theholding section 211, and one end of the lead-insection 213 is connected with the other end of the connecting section 212; a holding space a for holding a top tongue of the slider is formed between the twoholding sections 211 and the two connecting sections 212 of the two clamping sides 21, and a lead-in space b for guiding the slider is formed between the two lead-insections 213 of the two clamping sides 21, and the size of the holding space a is larger than that of the lead-in space b. - Specifically, in an example, the
holding sections 211, the connecting sections 212 and the lead-insections 213 are planar, the two connecting sections 212 are obliquely arranged at the twocorresponding holding sections 211 respectively, and ends of the two connecting sections 212 away from the twocorresponding holding sections 211 are close to each other. Thus, it is easy to machine the clamping sides 21. - Furthermore, each of the
elastic clamping tongues 2 further comprises a lead-inside 22 adjacent to the clamping side 21 and asidestep side 23 opposite to the clamping side 21, and the width between thesidestep side 23 and the clamping side 21 decreases gradually from the end close to thebody 1 to the end away from thebody 1. Thus, the width of ends of theelastic clamping tongues 2 away from thebody 1 decreases gradually to facilitate theelastic clamping tongues 2 to snap into the slider. - Furthermore, a
first arc chamfer 24 is formed between the clamping side 21 and the lead-inside 22, and/or asecond arc chamfer 25 is formed between the lead-inside 22 and thesidestep side 23. Thus, theelastic clamping tongues 2 snap into the slider more smoothly. - In an example of the present invention, the cross-sectional shape of the
groove 11 is arc. Of course, the cross-sectional shape of thegroove 11 can also be V-shaped, square or other irregular shapes without limitation, as long as thegroove 11 can match the shape of the upper end of the slider. - In an example of the present invention, the two
elastic clamping tongues 2 are provided withguide projections 4 on the upper side and/or the lower side respectively, each of the twoguide projections 4 comprises aguide surface 41, and the guide surfaces 41 of the twoguide projections 4 are parallel to each other and extend along the lengthwise direction of the zipper. Thus, the movement of the slider can be guided by arranging theguide projections 4 on the upper side and/or the lower side of the twoelastic clamping tongues 2 respectively, so as to facilitate the leading-in of the twoelastic clamping tongues 2 into the slider. - Furthermore, each of the
guide projections 4 further comprises astop surface 43 perpendicular to theguide surface 41. Thus, each of theguide projections 4 has a right-angle lead-in structure for guiding and limiting the slider. - Furthermore, a
third arc chamfer 42 is formed between theguide surface 41 and thestop surface 43 of each of theguide projections 4. Thus, it is easy to guide theguide protrusions 4 into the slider. - In an example of the present invention, the sealed zipper top stop further comprises a
stiffener 3, thestiffener 3 is arranged on one side of thebody 1 away from the slider and extends along the lengthwise direction of the zipper, and two sides of thestiffener 3 are provided with the clampinggrooves 5 for tapes to pass through. Thus, the length of the sealed zipper top stop along the lengthwise direction of the zipper is longer, and the connection between the sealed zipper top stop and tapes can be strengthened by arranging thestiffener 3. - The present invention further provides a zipper, comprising a left tape, a right tape, left zipper teeth, right zipper teeth, a slider and a sealed zipper top stop according to any of the above examples, wherein the left tape and the right tape are arranged in parallel at an interval; the left zipper teeth are arranged at one side of the left tape close to the right tape, the right zipper teeth are arranged at one side of the right tape close to the left tape, and the slider is connected with the left zipper teeth and the right zipper teeth; the sealed zipper top stop is connected with the left tape and the right tape and is located at an end of the zipper.
- The technical features of the above examples can be combined in any way. For brevity, not all possible combinations of the technical features of the above examples are described. However, it should be considered that the technical features are included in the scope of the specification provided that there is no contradiction in the combinations thereof.
- The above examples illustrate several examples of the present invention only, but should not be construed as limiting the scope of the present invention despite of specific and detailed description. It should be noted that those of ordinary skill in the art can make various changes and improvements without departing from the concept of the invention, which should be incorporated in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to appended claims.
