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 surface in the vicinity of a fully opened position of the door, and FIG. 2 is a plan view of the door stop in FIG. Is a cross-sectional explanatory view of the door stop of FIG.
FIG. 4 is a view of the rotating body of FIG. 1 seen from above, FIG. 5 is a view of the rotating body of FIG. 1 seen from below, and FIG. 6 is a doorway showing another embodiment of the doorway of the present invention. 7 is a schematic explanatory view showing a state of being attached to the floor surface in the vicinity of the fully open position and FIG. 7 is a sectional explanatory view of the main body portion of FIG.

The door stop shown in FIGS. 1 to 3 is supported by the pedestal 1 installed on the floor surface and the pedestal 1 so as to be rotatable about an axis 7 substantially perpendicular to the surface of the pedestal 1, and , A rotating body 2 having a contact surface 2a capable of contacting the door D, a cover portion 5 provided on the pedestal 1, a ring 12 engaging with a hook 4 fixed to a lower portion of the door D, and a ring. 12 is attached, and is composed of a rotary plate 13 rotatably attached near the top of the cover 5.

As shown in FIG. 2, since the ring 12 can be pivotally rotated together with the rotary plate 13, the ring 12 is oriented almost in the normal direction of the door D regardless of the angle of the pedestal 1. Therefore, the ring 12 can be always engaged with the hook 4 on the door D in the best state.

When the ring 12 is not used, both ends of the ring 12 can be housed inside the rotary plate 13 as described later.

The respective parts of the door stop according to this embodiment will be described below with reference to FIGS.

The pedestal 1 is made of a metal material or a hard synthetic resin, and has a through hole 1a into which a wood screw (not shown) for fixing to the floor is inserted. The pedestal 1 is provided with a cover portion 5 for covering a part (preferably about half) of the rotating body 2 in order to protect the rotating body 2. Cover part 5
Is integrally formed with the pedestal 1 or fixed to the pedestal 1 by welding or the like.

It is preferable that at least a part of the cover portion 5 has a spherical shape (preferably, a substantially spherical shape is divided into four) so that a pedestrian or the like is not easily caught. .

Through hole 5 formed near the top of cover 5
A rotary plate 13 is rotatably attached to a.
As shown in FIGS. 2 and 3, a flange 13 a protruding outward is locked to a peripheral portion of the through hole 5 a of the cover portion 5 on the peripheral edge of the rotary plate 13.

When the rotary plate 13 is attached, the rotary plate 13 may be inserted into the through hole 5a from below after the shaft 7 and the rotary body 2 are removed from the pedestal 1.

The rotating plate 13 is formed with a pair of through holes 13b. The U-shaped ring 12 is inserted into and retracted from each of the pair of through holes 13b. The end 12b of the U-shaped ring 12 is inserted into the through hole 13b and then flattened to prevent the ring 12 from coming off the rotary plate 13.

The ring 12 need only be rotatably attached to the cover portion 5, and an annular ring is used as the cover portion 5.
It may be rotatably attached to the top of the.

Like the space 6 inside the cover 5, the rotating body 2 has a shape obtained by substantially dividing a spherical body into four,
A portion of the rotating body 2 in the vicinity of the contact surface 2a extending in the vertical direction projects to the outside of the cover portion 5, and the other portions of the rotating body 2 form a slight clearance with the inner peripheral surface of the cover portion 5. It is housed inside the cover 5. Therefore, when the door D or the plate 14 (see FIG. 6) hits the contact surface 2a of the rotating body 2, the rear end of the rotating body 2 is supported by contacting the inner peripheral surface of the cover portion.

The rotating body 2 is rotatably supported by a shaft 7 fixed to the base 1. The upper end of the shaft 7 is not fixed and is only inserted into the arc-shaped groove 13c of the rotary plate 13 extending in the direction perpendicular to the paper surface of FIG. 3, so that the rotation of the rotary plate 13 is not hindered. However, since the projection 13d of the rotary plate 13 is in contact with the upper end portion of the shaft 7, even if the door collides with the contact surface 2a of the rotating body, it is possible to withstand the impact at the time of collision.

As shown in FIG. 2, the rotating body 2 is supported so as to be rotatable at least by an angle θ (preferably about 20 to 30 °) at which the contact surface 2a is not hidden by the cover portion 5. Good. Therefore, the door D or the plate 14 (see FIG. 6) can always be brought into surface contact with the contact surface 2a even if there is a backlash or a mounting error of the door D, and the effect of stopping the door D is high.

Further, in this embodiment, in order to regulate the rotation angle of the rotating body 2, a stopper 11 having a substantially wedge shape is provided integrally on the upper surface of the pedestal 1 so as to project, and the rear end of the rotating body 2. A notch 2c provided on the side is provided. The rotation of the rotating body 2 is restricted within a predetermined range by the stoppers 11 contacting the wall surfaces on both ends of the notch 2c. In place of the notch 2c and the substantially wedge-shaped stopper 11, an arc-shaped recess is formed on the bottom surface 2c of the rotating body 2, and the tip of the pin-shaped stopper is brought into contact with the wall surface of this recess. May be.

The inside of the rotating body 2 is the ring 12
The space portion 2d is formed so that both ends of the ring 12 can be inserted when the ring 12 is stored. The space 2d is located on the rear side (left side in FIGS. 4 to 5) of the shaft hole 2f into which the shaft 7 is inserted. Although the present invention does not limit the size of the space 2d, the size of the space 12d is preferably such that the end 12b of the ring 12 can easily move up and down.

Further, in this embodiment, as shown in FIGS. 4 to 5, in order to reinforce the rotating body 2, the space 2d is formed.
A rib 2e is integrally formed with the rotating body 2 so as to pass through the inside. By reinforcing the rotating body 2 with the ribs 2e, even if the door D strongly collides with the contact surface 2a of the rotating body 2, the rotating body 2 (particularly the peripheral portion of the shaft hole 2f) is not damaged.

Further, as another embodiment of the door stop of the present invention, as shown in FIGS. 6 to 7, the magnet 3 and the plate 1 are provided in the door stop with the ring shown in FIGS.
There is a door stop with 4 more.

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 rotatable about an axis 7 substantially perpendicular to the surface of the pedestal 1,
In addition, the rotating body 2 is formed with a contact surface 2a capable of contacting the door D, the magnet 3 disposed inside the hole 2b formed in the contact surface 2a of the rotating body 2, and a magnetic body. , And a plate 14 fixed to the lower part of the door D. A tongue-shaped engaging portion 15 for engaging with the ring 12 is integrally formed on the upper end of the plate 14. The cover portion 5, the shaft 7, the ring 12, and the rotary plate 13 have the same structure as the door stop shown in FIGS.

The door stop shown in FIGS. 6 to 7 is a door D.
When it is desired to temporarily hold the plate in the fully open position, the plate 14 of the door D may be attracted to the magnet 3 on the rotating body 2 side.
When closing the door D, it is sufficient to close the door D slightly against the attractive force of the magnet 3. Further, when it is desired to firmly hold the door D in the fully open position for a long time, the ring 12 may be engaged with the engaging portion 15 at the upper end of the plate 14.

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 cross-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.

The rotating body 2 can be rotated by an angle θ (preferably about 20 to 30 °) such that at least the contact surface 2a is not hidden by the cover portion 5, as in the door stop shown in FIGS. Supported by. Therefore, the plate 14 on the door D side can always be brought into surface contact with the contact surface 2a and the magnet 3 even if there is rattling or mounting error of the door D, and as a result, the effect of stopping the door D is high, and
The door D can be stably held in the fully opened state, and the problem that the door D receives an external force and vibrates is eliminated.

Various magnets such as permanent magnets and electromagnets can be adopted as the magnet 3, but the magnet 3 of the present embodiment shown in FIG. 7 holds the magnet body 9 and the magnet body 9 therebetween. The front surface 10 of the magnetic plate 10 is composed of a pair of magnetic plates 10.
The plate 14 can be attracted to a.
The shaft 7 is inserted into the through hole 10b of the magnetic plate 10.

The outer diameter of the magnet 3 is the hole 2 of the rotor 2.
A material slightly smaller than the size of b is used. As a result, the magnet 3 is housed inside the hole 2b of the rotating body 2 so as to be located deeper than the contact surface 2a, and can be slightly moved in the front-rear direction of the rotating body 2 (left-right direction in FIG. 5). Up / down / left / right (up / down direction in FIG. 5, and perpendicular to the paper surface)
It is provided so that it can slightly swing. Therefore,
The plate 14 always comes into contact with the surface of the magnet 3.
As a result, the door D can be more stably held in the fully opened state, and further problems such as the door D vibrating due to an external force are eliminated.

[0036]

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 that contacts the door can be surely brought into surface contact with the door. Therefore, the door stop fixed near the wall looks good.

Moreover, since the ring of the door stop is rotatably attached to the cover portion, the ring can be engaged with the hook on the door side in the best condition.

Further, by providing the magnet in the door stop according to the present invention, the door can be securely attracted to the magnet without being affected by the 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 it is not necessary to reattach the door stop.
