is doing.

The stopper piece 91 is formed of a metal that can be attracted by the magnet 40.
The arm portion 93 is formed to be narrower than the facing interval of the locking claw 61 of the locking portion 60, so that it can be positioned within the facing interval of the locking claw 61 when attracted by the magnet 40. .
On the other hand, since the distance between both ends of the pair of extending pieces 94 is formed wider than the facing distance of the locking claws 61, when the pair of extending pieces 94 are attracted by the magnet 40, The locking claw 61 cannot be positioned within the facing interval.

Next, the operation of the door stopper having the above configuration will be described with reference to FIGS.
First, as shown in FIGS. 5 and 6, the locking tool main body 90 is fixed in advance at a position where the door D is to be kept open on the floor surface.
Next, with the stopper main body 10 fixed to the door, when the door is opened and moved to a position where the locking tool main body 90 is fixed, it is attracted to the magnet 40 as shown in FIG. It rises from the base 92 on the free end side of the piece 91 and comes into contact with the back surface of the bottom member 50 at the position of the pocket 54.

Further, in this state, the locking claw 61 does not protrude from the bottom surface member 50, so that the stopper piece 91 is not locked to the pair of locking claws 61.
Even in this state, the attracted stopper piece 91 is not detached from the back surface of the position of the pocket 54 of the bottom surface member 50 unless a strong force is applied by the magnet 40 attracting the stopper piece 91. Thus, the open state of the door D is maintained.

However, when a force stronger than the attracting force of the magnet 40 is applied to the door by a strong pull or a strong wind, the door cannot be kept open.
Therefore, in order to ensure the open state of the door D, the operation piece 70 is pressed toward the door.
When the operating piece 70 is pressed, the operating piece 70 pivotally supported by the shaft body 100 presses the locking portion 60 by the operating portion 71, and the locking portion 60 is tilted forward around the shaft body 100. Since it moves, as shown in FIG. 6, the pair of locking claws 61 protrudes downward from the bottom surface member 50.

In this state, the arm portion 93 of the stopper piece 91 fits in the facing interval of the locking claw 61, but the extending piece 94 is wider than the facing interval of the locking claw 61. Is locked at the tip of the locking claw 61.
When the extended piece 94 is locked to the tip of the locking claw 61, when the door D is moved in the closing direction, the pair of locking claw 61 protrudes as shown in FIG. The leading ends are obstructed by the extension pieces 94 and cannot move any more, and the open state is maintained.

Then, in order to close the door D from the state in which the opening is held, the pressed operation piece 70 is pulled and returned to the original position.
When the operating piece 70 is pulled back to the original position, the action portion 72 of the operating piece 70 pivotally supported by the shaft body 100 presses the locking portion 60 below the shaft body 100, and the shaft body 100 is centered. As a result, the pair of locking claws 61 do not protrude from the bottom surface member 50 again as shown in FIG.

In this state, when the door D is closed manually, the magnet 40 only attracts the stopper piece 91, so the stopper piece 91 attracted to the magnet 40 can be easily removed and the door closed. Can do.
The pair of extending pieces 94 press the stopper piece 91 that is in a protruding state by the exciting action of the magnet 40 when the stopper piece 91 comes into contact with the stopper main body 10 by the exciting action of the magnet 40. Because it is formed so that it can move to the non-projecting state against the urging force of the primary holding part, even if the stopper piece 91 is attracted to the magnet 40, the door D can be lightly closed by human hands The door is not inadvertently held open by the locking claw 61 of the stopper body 10.

  In addition, by installing the magnet (40), the locking part (60) and the buffer wall (51) on the lower end surface of the door in the stopper main body (10), the lower end surface of the door can be used effectively to save the place. A door stopper can be installed without taking up a large space.

It is a disassembled perspective view of the door stopper seen from the door side. It is a disassembled perspective view of the door stopper seen from the non-door side. FIG. 3 is a perspective view of a door stopper that is different from the perspective view in a viewing direction. FIG. 4 is a front view of the stopper body on the side installed on the door.
