DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The door stop according to the present invention will be described in more detail with reference to the drawings. FIG. 1 is a schematic explanatory view showing a state in which a door stop according to an embodiment of the present invention is attached to a floor near a door fully open position, FIG. 2 is a plan explanatory view of the door stop in FIG. Is a sectional explanatory view of the door stop of FIG. 1,
FIG. 4 is a schematic explanatory view showing another embodiment of the door stop according to the present invention, in which a door stop is attached to a floor near a fully opened position of the door, and FIG. 5 is a sectional explanatory view of a main body part in FIG. is there.

The door stop shown in FIGS. 1 to 3 is supported by the pedestal 1 installed on the floor surface and rotatable about an axis 7 substantially perpendicular to the surface of the pedestal 1, and , A rotating body 2 having a contact surface 2 a capable of contacting the door D, and a cover portion 5 provided on the pedestal 1.

The pedestal 1 is made of a metal material and has a through hole 1 into which a wood screw (not shown) for fixing to the floor is inserted.
a is formed. The pedestal 1 includes a cover 5 that covers a part (preferably about half) of the rotator 2 to protect the rotator 2. The cover 5 is formed integrally with the pedestal 1 or is fixed to the pedestal 1 by welding or the like.

It is preferable that at least a part of the cover 5 has a spherical shape (preferably, a shape obtained by substantially dividing a sphere into four parts) so that a pedestrian or the like is hardly caught. .

The rotator 2 has a shape obtained by substantially dividing a sphere into four parts, like the space part 6 inside the cover part 5.
The portion near the contact surface 2a extending in the vertical direction of the rotating body 2 projects outside the cover 5, and the other portion of the rotating body 2 forms a slight clearance with the inner peripheral surface of the cover 5. It is housed inside the cover part 5. Therefore, when the plate 4 of the door D comes into contact with the contact surface 2a of the rotating body 2, the rear end of the rotating body 2 comes into contact with and is supported by the inner peripheral surface of the cover.

The rotating body 2 is rotatably supported on a shaft 7 fixed between the upper inner surface of the cover 5 and the pedestal 1. Since the shaft 7 is supported at both ends by the cover portion 5 and the pedestal 1, the rigidity is very high.
There is no fear that the shaft 7 will be distorted even if the foot is stepped on from above.

As shown in FIG. 2, the rotating body 2 is supported so that it can rotate at least by an angle θ (preferably about 20 to 30 °) such that the contact surface 2a is not covered by the cover 5. I just need. Therefore, even if there is a play or an installation error of the door D, the plate 4 on the door D side can always be brought into surface contact with the contact surface 2a, and the effect of stopping the door D is high.

In this embodiment, in order to regulate the rotation angle of the rotating body 2, a stopper 11 inserted into a hole 1b formed in the pedestal 1 and fixed by caulking or bonding is provided. An arc-shaped concave portion 2c formed on the bottom surface 2c of the rotating body 2 is provided. The tip of the stopper 11 formed in the recess 2c abuts on the wall surface of the recess 2c, so that the rotation of the rotating body 2 is restricted within a predetermined range. Instead of the concave portion 2c, a notch may be provided on the rear end side of the rotating body 2, and the tip of the stopper 11 may be brought into contact with the wall surface of the notch.

The above-mentioned door stop shown in FIGS. 1 to 3 is obtained when the rotating body 2 collides with the door D when the door D is fully opened.
While only stopping the door D, means for holding the door D in the fully open position may be provided.

Here, as an example of a conventional door stop having a fully open position holding function, there is a door stop 53 shown in FIGS. The door stop 53 includes a base 55 screwed to a male screw (not shown) standing on a floor 54 and a buffer 56 fixed to an upper portion of the base 55. With this configuration, when the door 50 is opened or closed, the door 50 or the knob 51 is moved to the furniture or cabinet 5 around the wall or the door 50.
2 can be prevented from being damaged.

Further, in order to keep the door 50 in the open state, the U-shaped stopper 57 inserted into the base 55 is pulled out, and a hook portion of a washer 58 with a hook provided on a side surface of the door 50 is provided. 59.

However, in the conventional door stop, the door 50
In order to keep the door fully open, it is necessary to pull out the stopper 57 from the base 55 on the floor and hook it on the hook on the door 50 side. Conversely, when closing the door 50, the stopper 5
It takes time to remove 7.

Therefore, in order to facilitate holding and opening the door fully open, as another embodiment of the door stop according to the present invention, a door provided with a magnet 3 and a plate 4 as shown in FIGS. There is a hit.

That is, the door stop shown in FIGS.
A pedestal 1 installed on the floor, and supported by the pedestal 1 so as to be able to rotate around an axis 7 substantially perpendicular to the surface of the pedestal 1,
A rotating body 2 having a contact surface 2a capable of contacting the door D; a magnet 3 disposed inside a hole 2b formed in the contact surface 2a of the rotating body 2; , And a plate 4 fixed to a lower portion of the door D. The cover 5 and the shaft 7 have the same configuration as the door stop shown in FIGS.

A hole 2b having a substantially rectangular cross section for accommodating the magnet 3 is formed in the contact surface 2a of the rotating body 2. The sectional shape of the hole 2b is not particularly limited to a substantially rectangular shape in the present invention, and may be, for example, a circular shape or a polygonal shape.

As in the case of the door stop shown in FIGS. 1 to 3, the rotating body 2 can be rotated by an angle θ (preferably about 20 to 30 °) at least so that the contact surface 2a is not covered by the cover 5. It only needs to be supported. Therefore, even if there is a play or an installation error of the door D, the plate 4 on the door D side can always be brought into surface contact with the contact surface 2a and the magnet 3, and as a result, the effect of stopping the door D is high, and
The door D can be stably held in the fully open state, and there is no problem such as the door D vibrating due to an external force.

As the magnet 3, various magnets such as a permanent magnet and an electromagnet can be employed. The magnet 3 of this embodiment shown in FIG. 4 sandwiches the magnet main body 9 and the magnet main body 9. A front surface 10 of the magnetic plate 10
The plate 4 can be attracted to a. The shaft 7 is inserted into the through hole 10b of the magnetic plate 10.

The magnet 3 has the outer dimensions of the hole 2 of the rotating body 2.
A material slightly smaller than the size of b is used. Thereby, the magnet 3 is housed so as to be located inside the hole 2b of the rotating body 2 and deeper than the contact surface 2a, and can move slightly before and after the rotating body 2 (in the horizontal direction in FIG. 5). Up, down, left and right (vertical direction in FIG. 5 and vertical direction on paper)
Is provided so as to be able to swing slightly. Therefore,
The plate 4 always comes into contact with the surface of the magnet 3. As a result, the door D can be held in the fully open state more stably, and further problems such as the door D vibrating under an external force are eliminated.

[0030]

According to the present invention, even when the front surface of the portion fixed to the floor surface is parallel to the wall, the contact surface of the rotating body contacting the door can be reliably brought into surface contact with the door. Therefore, the appearance of the door stop fixed near the wall is improved.

Further, by providing the door stop with a magnet according to the present invention, the door can be surely attracted to the magnet without being affected by backlash of the door. Therefore, even if there is a door mounting error or backlash, the backlash between the door and the magnet can be automatically absorbed by the door stop, and there is no need to reattach the door stop.
