Abstract

A smart zipper includes: a fastener stringer including two rows of zipper teeth and a joint at one end of the two rows of zipper teeth for fixedly connecting the one end of the two rows of zipper teeth; a slider, including two lateral limiting portions, the two lateral limiting portions having conductive properties, and the two lateral limiting portions respectively electrically contacting outer edges of the two rows of zipper teeth; and a resistance measuring chip electrically connected to the two lateral limiting portions of the slider respectively, wherein the resistance measuring chip, the slider and the fastener stringer form a conductive loop. The resistance measuring chip is used for measuring the resistance value of the conductive loop, and outputting a measurement signal. The smart zipper provided by the present disclosure can detect its own closed state. Therefore, the user can know the closed state of the zipper in real time to avoid embarrassment or property loss due to unclosed zipper.

First claim

The invention claimed is:

1. A smart zipper, comprising:
a fastener stringer comprising two rows of zipper teeth and an electric nonconductive joint at one end of the two rows of zipper teeth for fixedly connecting the one end of the two rows of zipper teeth, wherein each of the zipper teeth has an electric conductive outer edge and an electric nonconductive meshed portion;
a slider, comprising two lateral limiting portions; the two lateral limiting portions having conductive properties, and the two lateral limiting portions respectively electrically contacting outer edges of the two rows of zipper teeth; and
a resistance measuring chip electrically connected to the two lateral limiting portions of the slider respectively,
wherein, when the two rows of zipper teeth are at least partly meshed with each other, the resistance measuring chip, the two lateral limiting portions, the electric conductive outer edges of the at least partly meshed two rows of zipper teeth and the electric nonconductive joint together form a conductive loop, whereas the resistance measuring chip, the two lateral limiting portions and the electric nonconductive meshed portions of the at least partly meshed two rows of zipper teeth do not form a conductive loop, and
wherein the resistance measuring chip is used for measuring a resistance value of the conductive loop and outputting a measurement signal.

2. The smart zipper according to claim 1 , further comprising:
a wireless signal transceiver module which is signally connected with the resistance measuring chip and is used to receive measurement signals output by the resistance measuring chip and send the measurement signals to an external device.

3. The smart zipper according to claim 2 , wherein the wireless signal transceiver module is a Bluetooth module.

4. The smart zipper according to claim 3 , further comprising:
a button cell which is electrically connected with the resistance measuring chip and the wireless signal transceiver module for supplying power to the resistance measuring chip and the wireless signal transceiver module.

5. A garment comprising the smart zipper of claim 2 .

6. The smart zipper according to claim 2 , wherein the external device is a smart bracelet or a smart phone.

7. The smart zipper according to claim 6 , further comprising:
a button cell which is electrically connected with the resistance measuring chip and the wireless signal transceiver module for supplying power to the resistance measuring chip and the wireless signal transceiver module.

8. The smart zipper according to claim 2 , further comprising:
a button cell which is electrically connected with the resistance measuring chip and the wireless signal transceiver module for supplying power to the resistance measuring chip and the wireless signal transceiver module.

9. The smart zipper according to claim 8 , further comprising a pull tab, wherein the pull tab comprises two hooks that are not in contact with each other;
the slider further comprises a connecting portion for connecting the pull-tab, the connecting portion is provided with two buckles respectively at two sides facing the two limiting portions, the two buckles are respectively engaged with the two hooks of the pull tab.

10. The smart zipper according to claim 9 , wherein
in the slider, the buckle at each side of the connecting portion is electrically connected with the limiting portion at a corresponding side;
the two hooks of the pull tab have conductive properties;
the resistance measuring chips are respectively electrically connected with the two limiting portions of the slider through the two hooks of the pull tab, and the resistance measuring chip, the pull tab, the slider and the fastener stringer form the conductive loop.

11. The smart zipper according to claim 10 , wherein the resistance measuring chip, the wireless signal transceiver module and the button cell are all disposed in the pull tab.

12. The smart zipper according to claim 9 , wherein the resistance measuring chip, the wireless signal transceiver module and the button cell are all disposed in the pull tab.

13. A garment comprising the smart zipper of claim 12 .

14. The smart zipper according to claim 9 , wherein apart from the two lateral limiting portions, the buckles and two wires, other portions of the slider are insulated; apart from the two hooks, other portions of the pull tab are insulated.

15. The smart zipper according to claim 8 , wherein the resistance measuring chip, the wireless signal transceiver module and the button cell are all disposed in the slider.

16. A garment comprising the smart zipper of claim 15 .

17. A garment comprising the smart zipper of claim 1 .

18. The smart zipper according to claim 1 , wherein only the outer edges of the two rows of the zipper teeth are electrically connected to the conductive loop, the outer edge of each row of the zipper teeth is equivalent to a sliding resistor, as a meshed length of the at least partly meshed two rows of zipper teeth becomes longer, a resistance of the sliding resistor electrically connected to the conductive loop gradually increases and a resistance of entire conductive loop also increases.
