Description

  The present invention relates to a door stop used to maintain an open posture of a door.

  2. Description of the Related Art Conventionally, a door stop is used in order to maintain an open posture of the door, and as this door stop, a structure in which a hook is hooked on a door side receiving member is well known. However, when such a conventional door stop is used, it is necessary to bend the waist and hook or hang the hook on the receiving tool by hand, so that the work is troublesome. In addition, if you forget to hook the hook on the receiving tool, the door will be blown by the wind and suddenly closed with a loud noise. There was also a problem that there was a risk of being caught.

  In view of these problems, various types of door stops have been proposed in recent years. For example, in Patent Document 1, when a door is opened, the hook-shaped locking portion of the door-side locking body is fitted into the concave locking portion of the vertically movable body of the door-to-door main body fixed to the floor. While the open state is maintained, a door stop is disclosed in which when the door is closed, the top surface of the vertically movable body is pushed down with a hand or foot to release the locking state between the hook-shaped locking portion and the concave locking portion. Yes.

  Further, in Patent Document 2, when the door is opened, the door-side flexible stopper is locked to the door-holding main body fixed to the floor to maintain the door open state. There is disclosed a door stop in which a lower part of a movable body formed in an arc shape is pressed with a toe from the opposite side of the door opening direction to release the locked state between the stopper and the main body of the door stop.
