Abstract

A latching mechanism including a pedestal provided with a first hole on the surface, a second member provided with a second hole opened at a position overlapping with the first hole, and a fastening member whose one end part is inserted into and pulled from the first hole through the second hole, so that the second member is engaged with the pedestal in an attachable and detachable manner. In the mechanism, the fastening member is inserted through the second hole into the first hole and then rotated such that an outer shape of the one end part intersects with one of the first hole and the second hole so that the second member is mounted onto the pedestal, and then it is rotated further or reversely so that the second member is separated from the pedestal.

First claim

What is claimed is:

1. A helmet latching mechanism comprising: a pedestal fixed on a surface of a helmet, the helmet being provided as a first member, the pedestal being provided with a first hole in a substantial center part viewed from a position immediately above the surface; a second member placed on a surface of the pedestal and provided with a second hole substantially congruent to the first hole and opened at a position overlapping with the first hole; and a fastening member whose one end part is inserted into and pulled from the first hole through the second hole so that the second member is attached to the pedestal in an attachable and detachable manner, wherein the one end part is inserted through the second hole into the first hole and then the other end part opposite to the one end part is rotated about an axis in a direction of the insertion such that an outer shape of the one end part viewed from the direction of insertion intersects with an outer shape of the first hole and the second hole, so that the second member is mounted onto the pedestal, and wherein the other end part is rotated about an axis in the direction of insertion such that the outer shape of the one end part viewed from the direction of insertion fits exactly to the outer shape of the first hole and the second hole, so that the second member is separated from the pedestal.

2. The latching mechanism according to claim 1 , wherein the pedestal includes: an attachment part for fixing to a surface of the first member; and a ridge part for supporting the second member.

3. The latching mechanism according to claim 1 , wherein: the one end part is a leg part inserted into the first hole and the second hole; the other end part is a knob part used for the rotating; and a neck part is included that connects the one end part to the other end part and that is in contact with a surface of the second member.

4. The latching mechanism according to claim 2 , wherein: the one end part is a leg part inserted into the first hole and the second hole; the other end part is a knob part used for the rotating; and a neck part is included that connects the one end part to the other end part and that is in contact with a surface of the second member.

5. A helmet provided with a latching mechanism comprising:
a pedestal fixed on a surface of a shell and provided with a first hole in a substantial center part viewed from a position immediately above the surface;
a visor placed on a surface of the pedestal and provided with a second hole substantially congruent to the first hole and opened at a position overlapping with the first hole; and
a fastening member whose one end part is inserted into and pulled from the first hole through the second hole so that the visor is attached to the pedestal in an attachable and detachable manner, wherein
the one end part is inserted through the second hole into the first hole and then the other end part opposite to the one end part is rotated about an axis in a direction of the insertion such that an outer shape of the one end part viewed from the direction of insertion intersects with an outer shape of the first hole and the second hole, so that the visor is mounted onto the pedestal, and wherein
the other end part is rotated about an axis in the direction of insertion such that the outer shape of the one end part viewed from the direction of insertion fits exactly to the outer shape of the first hole and the second hole, so that the visor is separated from the pedestal.

6. The helmet according to claim 5 , wherein the pedestal includes: an attachment part for fixing to a surface of the shell; and a ridge part for supporting the visor.

7. The helmet according to claim 5 , wherein: the one end part is a leg part inserted into the first hole and the second hole; the other end part is a knob part used for the rotating; and a neck part is included that connects the one end part to the other end part and that is in contact with a surface of the visor.

8. The helmet according to claim 6 , wherein: the one end part is a leg part inserted into the first hole and the second hole; the other end part is a knob part used for the rotating; and a neck part is included that connects the one end part to the other end part and that is in contact with a surface of the visor.

9. The helmet according to claim 5 , wherein: the visor is provided with a third hole substantially congruent to the second hole and opened at a position overlapping with the first hole; the fastening member is inserted into and pulled from the first hole through the third hole so that the visor is attached to the pedestal in an attachable and detachable manner; the one end part is inserted through the third hole into the first hole and then the other end part is rotated about an axis in the direction of insertion such that an outer shape of the one end part viewed from the direction of insertion intersects with an outer shape of the first hole and the third hole, so that the visor is mounted onto the pedestal; and the other end part is rotated about an axis in the direction of insertion such that the outer shape of the one end part viewed from the direction of insertion fits exactly to the outer shape of the first hole and the third hole, the visor is separated from the pedestal.

10. The helmet according to claim 6 , wherein: the visor is provided with a third hole substantially congruent to the second hole and opened at a position overlapping with the first hole; the fastening member is inserted into and pulled from the first hole through the third hole so that the visor is attached to the pedestal in an attachable and detachable manner; the one end part is inserted through the third hole into the first hole and then the other end part is rotated about an axis in the direction of insertion such that an outer shape of the one end part viewed from the direction of insertion intersects with an outer shape of the first hole and the third hole, so that the visor is mounted onto the pedestal; and the other end part is rotated about an axis in the direction of insertion such that the outer shape of the one end part viewed from the direction of insertion fits exactly to the outer shape of the first hole and the third hole, the visor is separated from the pedestal.

11. The helmet according to claim 7 , wherein: the visor is provided with a third hole substantially congruent to the second hole and opened at a position overlapping with the first hole; the fastening member is inserted into and pulled from the first hole through the third hole so that the visor is attached to the pedestal in an attachable and detachable manner; the one end part is inserted through the third hole into the first hole and then the other end part is rotated about an axis in the direction of insertion such that an outer shape of the one end part viewed from the direction of insertion intersects with an outer shape of the first hole and the third hole, so that the visor is mounted onto the pedestal; and the other end part is rotated about an axis in the direction of insertion such that the outer shape of the one end part viewed from the direction of insertion fits exactly to the outer shape of the first hole and the third hole, the visor is separated from the pedestal.

12. The helmet according to claim 8 , wherein: the visor is provided with a third hole substantially congruent to the second hole and opened at a position overlapping with the first hole; the fastening member is inserted into and pulled from the first hole through the third hole so that the visor is attached to the pedestal in an attachable and detachable manner; the one end part is inserted through the third hole into the f
