First, the door stop body 1 will be described with reference to FIGS.

The door stop body 1 is at least partially made of a magnetic material, and is composed of a plate 3 provided on the floor and an abutment 4 provided above the plate 3. It is a flat type door stop that does not protrude.
The door stop body 1 is fixed to the floor surface with screws or an adhesive.

For example, the door stop body 1 is made of a metal magnetic material such as iron or steel, and the plate 3 and the contact body 4 are integrally formed so as to be easily manufactured and obtain high strength. Is preferred. Alternatively, the plate 3 may be formed of iron or steel, the abutment 4 may be formed of an elastic member such as rubber or synthetic resin, and the plate 3 and the abutment 4 may be connected to each other with a screw or an adhesive. .

It is preferable that the height of the contact body 4 is set to a height that does not protrude from the floor as much as possible so that the appearance does not deteriorate and the user does not catch on the foot. For example, in the present embodiment, it is preferable to set the height of the contact body 4 to about 5 mm or less from the floor surface, and more preferably to about 3 mm or less. If it is about 5 mm or less from the floor, a pedestrian or a transported object can ride on the contact body 4 with almost no resistance.

On the other hand, it is preferable that the thickness of the plate 3 is small, but in order to give a predetermined strength, the thickness of the plate 3 is 0.5 to 1..
Preferably, it is set to about 5 mm. Also, the magnet body 2
It is preferable that the outer peripheral edge 3a of the plate 3 is inclined so as to rise upward from the outside to the inside of the plate 3 so that b can ride on the plate 3 reliably.

Next, the magnet 2 will be described. As shown in FIGS. 1 and 5, the magnet 2 has a concave portion 2 that opens downward.
In this case, the magnet body 2b is housed inside the case 2a in which e is formed. A plate 2c is formed on the side surface of the case 2a, and screw holes 2d for screwing to the door D are formed at both ends of the plate 2c. The magnet 2 is embedded in a hole formed by a counterbore near the lower end of the door, and the plate 2c is fixed to the outer surface of the door. The case 2 in which the magnet body 2b is stored
a may protrude from the outer surface of the door.

The magnet 2 is provided such that the lower surface thereof is generally flush with the lower surface of the door, and the distance between the lower surface and the floor surface is generally about 3 to 4 mm when the door is mounted. Is disposed so as to be located about 3 to 4 mm above the floor surface.

Since the magnet body 2b is covered with a synthetic resin cover 2f having a thickness that does not excessively weaken the magnetic force, the magnet body 2b hits or rubs on the floor or the upper surface of the casing 3. No chipping or wear.

The fitting dimension between the concave portion 2e and the cover 2f is set so that at least a part of the magnet main body 2b can protrude and retract to the outside. Moreover, in the present embodiment, the hook 2g extending upward from the cover 2f.
However, as shown in FIG.
Since it engages with the concave portion 2i formed inside a, the maximum protrusion amount of the magnet main body 2b can be regulated and the magnet main body 2b can be prevented from falling off. In addition, the magnet main body 2b is located rearward of the hook 2g (right side in FIG. 5) when there is a pair of hooks 2g as viewed from the left side in FIG. 5, but frontward in the region between the pair of hooks 2g (see FIG. (See FIGS. 7 and 8).

Further, as shown in FIG.
A stopper 5 made of a magnetic material is provided on the inner surface of the concave portion 2e of FIG. The stopper 5 is manufactured such that the force applied to the magnet main body 2 b is smaller than that of the plate 3.

For example, the stopper 5 is provided on the plate 3

7 is manufactured such that the cross-sectional area in the horizontal cross section is smaller than the area on the upper surface of the plate 3. The stopper 5 is buried vertically from the deep end face of the concave portion 2e.

By the stopper 5, the magnet main body 2b is
As shown in FIG. 6, when it is located far from the plate 3, the case 2 a
Protected inside. On the other hand, as shown in FIGS. 7 and 8, when the magnet main body 2 b is located substantially above the plate 3, the force of being pulled toward the plate 3 becomes stronger than the stopper 5, so that the magnet main body 2 b is separated from the case 2 a. It protrudes downward and is attracted to the plate 3. Therefore, the magnet 2 and the plate 3 can be strongly attracted.

Instead of providing the stopper 5, a weak spring, that is, a spring that gives the magnet body 2b an elastic force weaker than the attraction force between the magnet body 2b and the plate 3 may be provided inside the case 2a. The same operation as the stopper 5 can be achieved.

As shown in FIG. 6, while the door D is moving in the opening direction, when the distance between the magnet 2 and the plate 3 is greater than near the fully opened position, the magnet body 2b is It does not move while being sucked.

As shown in FIG. 7, when the door D is near the fully open position, the distance between the magnet 2 and the plate 3 becomes small, so that the magnet body 2b is separated from the stopper 5 and downward from the case 2a. The magnet 2 (specifically, the magnet main body 2 b) is attracted to the attraction surface 3 a of the plate 3 while projecting.

Then, as shown in FIG. 8, when the door D reaches the fully opened position, the magnet 2 and the contact surface 4a of the contact member 4 come into surface contact. Since the magnet main body 2b is attracted to the plate 3, the door D is locked in the fully opened state.

On the other hand, when it is desired to close the door D from the fully opened state, if the door D is moved slightly stronger in the closing direction against the attraction force between the magnet main body 2b and the plate 3,
The lock can be easily released and the door D can be closed.
Then, when the door D returns to the vicinity of the position shown in FIG.
The magnet body 2b is housed inside the case 2a by attracting the stopper 5 again.
