Abstract

Stop member includes: a first member including a first insert to be inserted into a slider via a rear mouth of the slider, and a first base positioned rearward of the first insert; and a second member including a second insert to be inserted into the slider via a slit extending between the rear mouth and a front mouth of the slider, and a second base to be overlaid onto the first base. The first and second bases are configured to effect magnetic attraction and/or repulsion between the first and second bases when the first and second bases are overlaid. The second base rotates relative to the first base in accordance with the magnetic attraction and/or repulsion to allow the second insert to pivot toward the slit.

First claim

What is claimed is:

1. A stop member comprising:
a first member including a first insert inserted into a slider via a rear mouth of the slider, and a first base positioned rearward of the first insert and including a first permanent magnet; and
a second member including a second insert inserted into the slider via a slit extending between the rear mouth and a front mouth of the slider, and a second base locatable onto the first base and including a second permanent magnet,
wherein the first and second bases are configured to effect (i) magnetic attraction between the first and second permanent magnets when the first and second bases are overlaid or (ii) both of magnetic attraction and repulsion between the first and second permanent magnets when the first and second bases are overlaid, and
wherein the second base rotates relative to the first base in accordance with the magnetic attraction or both of the magnetic attraction and repulsion in a direction such that the second insert pivots toward the slit.

2. The stop member of claim 1 , wherein the first and second bases are configured to effect magnetic attraction between the first and second bases when the first and second bases are overlaid, and
wherein the second base rotates relative to the first base as the first and second bases come closer in accordance with the magnetic attraction.

3. The stop member of claim 1 , wherein in accordance with the magnetic attraction, the second base moves closer to the first base in an axial direction of a rotational axis regarding the pivoting of the second insert and accordingly, the second insert pivots about the rotational axis.

4. The stop member of claim 1 , wherein the first and second bases are configured to effect magnetic repulsion when the first and second base are overlaid, and the second base rotates relative to the first base in accordance with the magnetic repulsion.

5. The stop member of claim 4 , wherein the first and second bases are engageable in a rotatable manner.

6. The stop member of claim 1 , wherein each of the first and second permanent magnets has first and second poles arranged in a plane crossing or orthogonal to a rotational axis regarding the pivoting of the second insert.

7. The stop member of claim 1 , wherein one of the first and second bases includes a sloped surface that extends about a rotational axis regarding the pivoting of the second insert, and the other one of the first and second bases includes a sliding portion that slides on the sloped surface.

8. The stop member of claim 1 , wherein one of the first base and the second base is provided with an axial portion, and an other one of the first base and the second base is provided with a receiving portion that receives the axial portion.

9. The stop member of claim 8 , wherein the first base is provided with the axial portion, the first base has a first housing for housing the first permanent magnet, and the first housing has a bottom positioned in a proximity of an end of the axial portion.

10. The stop member of claim 8 , wherein the second base is provided with the receiving portion, the second base has a second housing for housing the second permanent magnet and the second housing has a bottom positioned in a proximity of a bottom of the receiving portion.

11. A slide fastener including the stop member of claim 1 .

12. The stop member of claim 1 , wherein (i) the first permanent magnet has no hole, and the second permanent magnet has no hole; and/or (ii) the second permanent magnet is thinner than the first permanent magnet.

13. The stop member of claim 1 , wherein one of the first base and the second base is provided with an axial portion, and an other one of the first base and the second base is provided with a receiving portion that receives the axial portion, the axial portion being adapted to house one of the first permanent magnet and the second permanent magnet.
