Locking member, door stop, and rod locking system

A door stop comprising:

• a rod system that is to be attached to a door and that includes a rod that extends toward a floor;
• and
• a rod locking system that is disposed on the floor and that is for locking the door in an opened state by locking the rod,
• wherein the rod locking system includes a locking member that is movable along the floor, the locking member including a speed regulation path portion for regulating entering speed of the rod by causing the rod to fluctuate, wherein the rod enters due to a motion of the door in a direction to open, and a locking portion for restricting movement of the rod by locking the rod whose entering speed is regulated,
• wherein the speed regulation path portion extends in a vertical direction that is perpendicular to a width direction of the locking member, and
• wherein the speed regulation path portion includes rod receiving portions that are disposed at a start edge and an end edge of the speed regulation path portion, respectively, wherein the rod receiving portions are shaped to receive an outer peripheral surface of the rod,
• wherein a height difference is formed, by a recess surface portion of the speed regulation path portion and a flat ascending portion of the speed regulation path portion, at a bottom portion of the speed regulation path portion to be contacted by the rod, the flat ascending portion being connected to the recess surface portion, and
• wherein each one of the rod receiving portions receives the rod that enters the speed regulation path portion and returns the rod to the other one of the rod receiving portions, and the height difference of the bottom portion causes the rod to fluctuate in a forward and backward direction by contacting the rod so as to regulate the entering speed of the rod.

A rod locking system that is included in a door stop for locking a door in an opened state and that is for releasably locking movement of a rod that is provided in the door and that extends toward a floor, the rod locking system comprising:

• a locking member that is movable along the floor, the locking member including a speed regulation path portion for regulating entering speed of the rod by causing the rod to fluctuate, wherein the rod enters due to a motion the door in a direction to open, and a locking portion for restricting movement of the rod by locking the rod whose entering speed is regulated,
• wherein the speed regulation path portion extends in a vertical direction that is perpendicular to a width direction of the locking member, and
• wherein the speed regulation path portion includes rod receiving portions that are disposed at a start edge and an end edge of the speed regulation path portion, respectively, wherein the rod receiving portions are shaped to receive an outer peripheral surface of the rod,
• wherein a height difference is formed, by a recess surface portion of the speed regulation path portion and a flat ascending portion of the speed regulation path portion, at a bottom portion of the speed regulation path portion to be contacted by the rod, the flat ascending portion being connected to the recess surface portion, and
• wherein each one of the rod receiving portions receives the rod that enters the speed regulation path portion and returns the rod to the other one of the rod receiving portions, and the height difference of the bottom portion causes the rod to fluctuate in a forward and backward direction by contacting the rod so as to regulate the entering speed of the rod.
