Description

  The present invention relates to a door stopper for holding a door in an open state and preventing the door from colliding with an open wall surface or the like.

Conventionally, a door stopper for holding a door in a predetermined position has been used in order to hold the door in an open state or prevent the opened door from colliding with a wall surface.
As a door stopper, a member such as a metal fitting provided on the door side is locked with a short columnar member protruding upward from the floor surface, or a position where the door is desired to be held There are various forms such as one that holds the door by unfolding the metal fitting attached to the door and using the metal fitting as a brace between the door and the floor.
However, the former is inconvenient because the columnar metal fitting protrudes from the floor surface, which may interfere with the cleaning of the floor surface or hit the foot.
In addition, before storage, there is a problem that the columnar hardware is not able to be attached because it gets in the way, and the place where it can be used is limited.
Furthermore, in the latter case, it is necessary to deploy the metal fittings at a position where the door is desired to be held, and the operation is complicated. At the time of holding the door, only the metal fitting is supported to support the door, so a strong force is applied. There is a possibility that the door will come off.

In order to solve such problems, various door stoppers have been developed (see, for example, Patent Document 1).
Patent Document 1 discloses a door stopper that is embedded in the floor when the door stopper is not used and can protrude upward from the floor surface when used.
The door stopper is embedded in the floor while being housed in the guide cylinder, and is stored in the guide cylinder (ie, below the floor surface) by a latching mechanism when not in use. A spring is attached to the door stopper. When the door stopper is housed in the guide cylinder, the door stopper is biased upward by the spring, but is prevented from moving upward by the latching mechanism. .
Therefore, if this latching mechanism is removed when the door stopper is used, the door stopper protrudes upward (that is, above the floor surface) by the biasing force of the spring, and stops at the position where the spring has become a natural length.
This protruding door stopper serves as a door stopper.

JP 2003-184418 A (2nd to 4th pages, FIGS. 1 and 2)

However, in the hardware of Patent Document 1, it is necessary to remove the latching mechanism in order to project the door stopper. For this reason, it is necessary for a person to press the upper end portion of the stopper in a state where it is housed in the guide tube by hand or foot, and the operation is complicated.
Further, since the door stopper is protruded and used as a door pad, the door surface may be damaged when the door stopper is brought into contact with the door surface when the door is held.
Furthermore, since the biasing force of the spring is used as direct power for causing the door stopper to protrude, there is a possibility that the spring will deteriorate and the biasing force will drop when used for a long time.

In order to solve such a problem, a door stopper as shown in FIG. 17 has been developed.
The door stopper S ′ includes a door member 100 and a floor member 200.
The door member 100 includes a fixing member 110 attached to the lower end side of the door and a locked member 111 disposed in the fixing member 110.
The locked member 111 is made of a magnetic metal.
The floor member 200 is a substantially circular member, and is formed with a hole 210 for locking the locked member 111. A magnet is disposed on the bottom surface of the hole portion 210. As shown in FIG. 17, when the door R is opened and the door member 100 moves above the hole portion 210, it is covered by the magnetic force of the magnet. The locking member 111 protrudes from the fixing member 110 and is attracted to the magnet. In this way, the locked member 111 is locked in the hole 210 of the floor member 200 by the magnetic force, and the door R is held.

With such a configuration, there is no need to operate the stopper itself in order to hold the door R, and the door is not damaged by the door stopper.
However, since the door member 100 is fixed to the surface of the door R, the door member 100 is visually recognized from the living space, which is not preferable in terms of design.
Further, although the columnar door stopper does not protrude from the floor surface, it is necessary to lock the member 111 to be locked. Therefore, the height of the floor member 200 is about 8.5 mm, and it is flat. It is hard to say that.
Furthermore, since the door member 100 is screwed to the door R, the screw for attaching the door bottom interferes with the screw for attaching the door member 100 to the door R, and the door member 100 and the door bottom cannot be used together. .

An object of the present invention is to solve the above-described problems, and to provide a door stopper that can easily hold a door without bothering human hands and has excellent design.
Another object of the present invention is to provide a door stopper that can be mounted in a flat state with the floor stopper member of the door stopper hardly projecting upward from the floor surface.

According to the first aspect of the present invention, there is provided a door stopper for holding the door in a predetermined position, wherein the door stopper includes a floor mounting member that is attached to the floor, and an upward direction from the lower surface of the door. A door burying member embedded in the formed hole, and the floor mounting member includes a locked member made of a magnetic material pivotally supported so as to be rotatable in the vertical direction, and the door burying member Is a cover that is attached to the door, a magnet that is held by the cover, a locking member that is disposed in proximity to the position where the magnet is disposed, and locks the locked member; The door burying member includes a magnet holding member that holds the magnet and the locking member, and a vertical movement for adjusting the distance of the magnet from the floor surface by moving the magnet holding member up and down. With the mechanism The vertical movement mechanism holds the magnet holding member so as to be movable up and down, and horizontally moves the horizontal movement member, and a bolt connected to the horizontal movement member for moving the horizontal movement member in the horizontal direction. A bolt receiving nut is fixed to the horizontal moving member, and the moving member is attached along the horizontal movement direction with the bolt leg side attached to the bolt receiving nut. The bolt leg side is attached to the bolt receiving nut and the head side protrudes to the outside of the door, and is attached along the horizontal movement direction. The magnet holding member includes the horizontal movement member. A shaft is disposed in a direction substantially perpendicular to the horizontal movement direction, and the horizontal movement member has a slit formed at an acute angle with respect to a horizontal plane. The shaft movement hole is formed as a loose hole along the horizontal movement direction, and the shaft is slidably supported along the slit, and the shaft movement hole has an end portion. The slider shaft, which is a spring pin fixed to the covering body, passes through the slider shaft, and when the force is not applied, the slider shaft fits into the shaft moving hole and the moving member rotates. When a force is applied due to this, the shaft can move along the shaft moving hole, and the horizontal moving member moves horizontally due to the rotation of the moving member, so that the shaft is moved into the slit. The magnet holding member is configured to move up and down along with the sliding along the slit of the shaft. When the door is moved and arranged in the magnetic field range of the magnet, the locked member is attracted by the magnetic force of the magnet and rotates in the direction of the magnet. It is solved by being locked.
Further, at this time, the locking member is formed with a locking claw formed in a hook shape on the lower end side, and a spring fixing portion on the end opposite to the side where the locking claw is formed. In addition, a shaft through hole penetrates between the locking claw and the spring fixing portion in a direction orthogonal to the entering direction of the locked member, and the shaft through hole serves as a spring pin. A configured shaft is inserted, and the locking member is configured to rotate in a horizontal direction and an entering direction of the locked member around the shaft through-hole into which the shaft is inserted; The other end portion side of the spring whose one end portion is fixed to the magnet holding portion is fixed to the spring fixing portion, and the spring is configured to apply a pressing force along the rotation direction of the support member. It is preferable that

Thus, the door stopper according to the present invention includes a door burying member and a floor mounting member, and this door burying member is buried in the lower end portion of the door.
Therefore, this door burying member does not protrude from the door surface and is hardly visible from the living space.
For this reason, it does not impair the aesthetics of the door design, interior, etc., which is advantageous in terms of design.
Further, the locked member provided in the floor mounting member is attracted to the magnet provided in the door burying member and locked to the locking member.
Therefore, when the door is brought close to the position where the floor mounting member is disposed, the locked member is automatically locked by the locking member, and the door is held at that position. For this reason, a door can be easily hold | maintained without bothering manpower.

At this time, the floor mounting member includes a support member that rotatably supports the locked member, the locked member is a plate-like member, and the support member is the plate-like member. It is preferable that the plate-shaped member has a storage hole for storing the.
Since a part having a certain volume such as a magnet is embedded on the door side, the floor side only needs to have a supporting member that supports the locked member and the locked member, and the height of the floor mounting member is It can be kept low.
Further, since the support member is a plate-like member and is stored in the storage hole formed in the support member, the height of the floor mounting member is lower than the sum of the thickness of the support member and the thickness of the locked member. It can be suppressed. That is, it is possible to keep the member to be locked lower by the thickness of the portion stored in the storage hole.
Thus, since the height of the floor mounting member can be kept low, even if the floor mounting member is mounted on the floor, there is almost no step between the floor and the floor mounting member, and the floor mounting member is almost flat.
Therefore, the floor mounting member does not interfere with cleaning or interfere with human walking.
In addition, since the floor mounting member can be mounted almost flat with the floor surface, even if there is an opening door such as storage, the movement of the opening door will not be hindered. Can also be installed. Therefore, the installation location is not limited.

  Further, at this time, the locked member locked by the locking member moves the door in a direction opposite to the direction in which the door has moved in order to lock the locked member by the locking member. When the lock is released by the force for causing the lock to release, it is preferable that a person does not need to perform a release operation to release the lock.

Further, at this time, the floor mounting member is provided with a plate-like support member that rotatably supports the locked member in the vertical direction, and the locked member is a plate-shaped member, A storage hole for storing the plate-like member is formed in the support member, and the door stopper released from the locking by the locking member is preferably stored in the storage hole by gravity. is there.
If comprised in this way, after a latching is cancelled | released, a to-be-latched member will return automatically to the state accommodated in the support member, and a floor mounting member will be in a flat state with a floor surface.
Therefore, it is not necessary for the person to perform an operation of placing the locked member in the original state.

  Further, at this time, the door burying member is provided with a magnet holding member for holding the magnet and the locking member, and the magnet holding member is moved up and down to adjust the distance from the floor surface of the magnet. If possible, the locked member can be arranged within the magnetic field range of the magnet by adjusting the height of the magnet holding member even if the distance between the floor and the lower surface of the door is different.

Further, at this time, the door burying member is provided with a magnet holding member for holding the magnet and the locking member, and a vertical movement mechanism for moving the magnet holding member up and down.
The vertical movement mechanism is configured to hold the magnet holding member so as to be movable up and down, to move horizontally, and to move the horizontal movement member in a horizontal direction connected to the horizontal movement member. The magnet holding member is provided with a shaft disposed in a direction substantially perpendicular to the horizontal movement direction of the horizontal movement member, and the horizontal movement member has a slit formed at an acute angle with respect to a horizontal plane. The shaft is slidably supported along the slit, and the horizontal moving member moves horizontally as the moving member moves horizontally. Preferably, the shaft slides along the slit, and the magnet holding member is configured to move up and down as the shaft slides along the slit. A.
If comprised in this way, a magnet holding member can be moved up and down via a horizontal movement member.

That is, the horizontal moving member is configured to move horizontally, the magnet holding member is configured to move up and down, and a shaft is provided in the magnet holding member in a direction substantially perpendicular to the horizontal moving direction of the horizontal moving member. A slit formed at an acute angle with respect to the horizontal plane is formed. Since the shaft of the magnet holding member is slidably disposed in the slit of the horizontal movement member, when the horizontal movement member is moved in the horizontal direction, the shaft slides along the slit. Since the shaft is disposed on the magnet holding member, the magnet holding member moves up and down as the shaft slides.
Thus, since the magnet holding member can be moved up and down with a simple structure, the distance between the floor and the lower surface of the door can be easily adjusted.

  Further, at this time, one end of the moving member is connected to the horizontal moving member, and the other end protrudes to the outside of the door, and the horizontal moving member is applied by applying a force to the other end. It is preferable that the position of the magnet holding member can be easily adjusted from the outside of the door at any time after the door embedded member is embedded in the door.

The door stopper according to the present invention includes a door embedded member including a magnet and a locking member, and a floor mounting member including a locked member. The locked member is attracted and locked by a magnet. The door can be easily held by locking with the member.
Therefore, an operation for holding the door is not necessary.
Moreover, since the door embedded member is embedded in the door, the door embedded member is not exposed to the living space, is advantageous in design, and a member attached to the lower portion of the door such as a door bottom can be used in combination.

Further, the floor mounting member is formed of a plate-like locked member and a support member for holding the locked member, and no special mechanism is built in. It can be installed easily without the need for construction work, and it can be installed in a state that is almost flat with the floor surface because the height is suppressed.
Therefore, the floor mounting member does not interfere with cleaning or interfere with human walking. In addition, since the floor mounting member can be mounted almost flat with the floor surface, even if there is an opening door such as storage, the movement of the opening door will not be hindered. Can also be installed. Therefore, the installation location is not limited.
Furthermore, since it does not protrude from the floor surface, it is advantageous in terms of design.

Further, since the position of the magnet can be adjusted in the vertical direction, even if the distance between the floor and the lower surface of the door is slightly different, it can be dealt with by adjusting the magnet position.
Furthermore, since the adjustment of the magnet position can be easily performed from the outside of the door, the adjustment can be performed at any time even after the door embedded member is embedded in the door.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Note that the configuration described below does not limit the present invention and can be variously modified within the scope of the gist of the present invention.
The present embodiment relates to a door stopper that can easily hold a door without bothering human hands, is excellent in design, and can be mounted on a floor in a flat state.

That is, the free end side of the wall extending substantially horizontally (substantially perpendicular to the front plate 11A) in the inner direction (Y direction side in FIG. 2) of the front plate 11A is bent substantially vertically downward. .

Further, a washer slit 11k is formed at the inner corner of the adjustment bolt mounting member 11c in the upward direction. This washer slit 11k is a slit for disposing the washer 20b.
Further, a bolt hole 11d is formed at a position where the adjustment bolt mounting member 11c is aligned with the adjustment bolt hole 11b.
The adjustment bolt 20 is attached to the slider 12 through the adjustment bolt hole 11b and the bolt hole 11d.
A rail (not shown) for sliding a magnet body 13 (described later) in the vertical direction may be formed on the surface disposed in the inner direction (Y direction side in FIG. 2) of the front plate 11A.

The back plate 11B is a plate body whose upper part is formed in a substantially semicircular shape, and has a height (length in the vertical direction) slightly shorter than the front plate 11A.
Further, a screw fixing member 11e is formed on a surface disposed in the inner side direction (the opposite direction side to Y in FIG. 2) of the back plate 11B.
The screw fixing member 11e is a substantially prismatic member, and a screw through hole 11f is formed in the vertical direction (Z direction in FIG. 2 and the opposite direction thereof).
Note that a rail (not shown) for sliding a magnet body 13 (described later) in the vertical direction may be formed on the inner surface of the back plate 11B (the side opposite to Y in FIG. 2). .

The cover 11C is a frame having a substantially U-shaped cross section, and is composed of two opposing substantially identical side walls 11g, 11g, and an upper wall 11h formed so as to bridge these.
Axial movement holes 11i and 11i are formed in the side walls 11g and 11g. The shaft movement holes 11i and 11i are formed in a slit shape from the substantially central part on the lower end side of the side walls 11g and 11g toward the upper direction (Z direction side in FIG. 2).

11 h of upper walls are formed in the shape curved in the dome shape.
A screw hole 11j is formed at the end of the upper wall 11h on the side where the back plate 11B is disposed.
The screw hole 11j is formed at a position aligned with the screw through hole 11f when the back plate 11B is disposed.
The screw hole 11j is a hole for inserting a screw for attaching the case 11 to the door R.
The screw passes through the screw through hole 11f and the screw hole 11j from the inside of the cover 11C and is screwed into the door R.

The cover 11C is arranged such that the free ends of the side walls 11g and 11g are directed downward (in the direction opposite to the Z direction in FIG. 2) and the upper wall 11h is disposed in the upper direction (the Z direction in FIG. 2). The
Further, the front plate 11A and the back plate 11B are arranged to face each other so as to cover the openings on both sides in the width direction of the cover 11C. At this time, the back plate 11B is disposed in the opening on the side where the screw hole 11j is formed.
At this time, the front plate 11A is arranged so that the screw holes 11a formed in the front plate 11A are located above the upper wall 11h.
As described above, the cover 11C is configured and has the appearance shown in FIG.

The slider 12 according to the present embodiment is a member for moving a magnet body 13 to be described later in the vertical direction, and the slider 12 itself is configured to be movable in the horizontal direction.
As shown in FIG. 3, the slider 12 according to the present embodiment includes slider side walls 12A and 12A and an adjustment bolt through wall 12B.

The slider side walls 12A and 12A are substantially rectangular plates, and the slider slits 12a and 12a are cut out from one corner portion in an oblique direction.
Further, shaft moving holes 12b and 12b are formed on the sides of the slider side walls 12A and 12A opposite to the sides where the slider slits 12a and 12a are cut out.
The shaft moving holes 12b and 12b are loose holes formed long in the width direction of the slider side walls 12A and 12A.

The adjustment bolt through wall 12B is a substantially rectangular plate body, and an adjustment bolt through hole 12c is formed in a substantially central portion.
In addition, an adjustment bolt receiving nut 12d is fixed at a position aligned with the adjustment bolt through hole 12c on the inner side surface (the surface on which the slider side walls 12A and 12A are disposed) of the adjustment bolt through wall 12B.

The slider shaft 12e is a known spring pin and is disposed so as to penetrate the shaft moving holes 12b and 12b.
The slider side walls 12A and 12A are arranged so that the sides on which the slider slits 12a and 12a are cut out face each other toward the lower side, and the slider side walls 12A and 12A are on the upper end side on the side where the slider slits 12a and 12a are cut out. The adjustment bolt penetrating wall 12B is disposed so as to bridge the slider side walls 12A and 12A.
The slider slits 12a and 12a correspond to slits.
The slider shaft 12e is disposed so as to penetrate the shaft moving holes 12b and 12b. Both ends of the slider shaft 12e are fixed to the side walls 11g and 11g of the cover 11C, respectively.

The slider shaft 12e is fitted in the shaft moving holes 12b and 12b in a state where no force is applied. However, when the force is applied, the width of the slit formed in the spring pin is reduced, so that the diameter of the spring pin is reduced. . Therefore, when a force is applied, the slider shaft 12e can move relative to the slider 12 along the shaft moving holes 12b and 12b (in the horizontal direction).
However, the slider shaft 12e cannot be moved because it is fixed to the cover 11C. Therefore, when a force is applied in the horizontal direction, the slider 12 itself moves in the direction in which the force is applied. It moves horizontally along the shaft moving holes 12b, 12b.
A known spring pin is used as the slider shaft 12e. In this embodiment, a wave spring pin is used. However, the present invention is not limited to this. For example, a spring pin in which a general substantially straight slit is formed may be used.

The magnet main body 13 according to the present embodiment is a member in which a magnet, a locking tool, etc., which will be described later, are incorporated in a substantially prismatic main body case 13A. Is formed.
The shaft penetrating portion 13a is disposed substantially at the center of the upper surface of the main body case 13A so as to be substantially parallel to the short side, and the magnet main body shaft 13b penetrates the inside. Both end portions of the magnet body shaft 13b protrude from both end sides of the shaft penetration portion 13a. Hereinafter, the projecting portions of the magnet body shaft 13b are referred to as shaft projecting portions 13c and 13c.
This magnet body shaft 13b corresponds to a shaft.
Further, a substantially rectangular opening 13d into which a locked member 22B of the floor mounting member 2 described later is inserted is formed on the bottom surface of the magnet body 13.

FIG. 4 is a cross-sectional view taken along line AA in FIG. 3 and shows the internal structure of the magnet body 13.
As shown in FIG. 4, a space 13B for arranging each member is formed in a predetermined shape inside the magnet body 13, and in this space 13B, a magnet 13e and a latch member 13f as a locking member are formed. The spring 13j and the lid 13k are built in.
Above the opening 13d, a locking space 13l for locking a locked member 22B of the floor mounting member 2 described later is formed.

The upper surface of the locking space 13l is formed in a slope shape having a substantially acute angle with respect to the horizontal plane, and a magnet arrangement hole 13m is formed above the slope surface.
A substantially cylindrical magnet 13e is fixed to the magnet mounting hole 13m.
Further, after the magnet 13e is arranged, the magnet arrangement hole 13m is closed by the magnet lid 13r having a substantially circular plate.
In addition, although a well-known magnet is used as the magnet 13e, a neodymium magnet is used in this embodiment.

Similarly to the upper surface of the locking space 13l, the magnet arrangement hole 13m is formed with a substantially acute angle (approximately the same angle as the angle formed between the upper surface of the locking space 13l and the horizontal surface) with respect to the horizontal plane. The magnet 13e is also fixed at a substantially acute angle with the horizontal plane.
A spring arrangement hole 13n is formed above the magnet arrangement hole 13m, and a spring 13j is arranged in the spring arrangement hole 13n.

This spring disposing hole 13n has a substantially acute angle with respect to the horizontal plane (the angle between the upper surface of the engaging space 13l and the horizontal plane and the magnet disposing hole 13m Therefore, the spring 13j is also fixed at a substantially acute angle with the horizontal plane.
The spring 13j presses a latch member 13f, which will be described later, against the inner wall surface of the space 13B.

A latch member 13f is disposed on the inner wall surface side of the space 13B opposite to the side on which the magnet 13e is disposed.
The latch member 13f is a member having a substantially J-shaped cross section, and a hook-like locking claw 13i is formed at the end.
The latch member 13f is arranged so that the side on which the locking claw 13i is formed faces downward and the locking claw 13i is disposed in the locking space 13l. The locking claw 13i is disposed so that the free end side faces the opening 13d.

  The other end side of the locking claw 13i (the end on the side where the locking claw 13i is not formed, hereinafter referred to as “spring fixing portion 13h”) is arranged at a position facing the opening side of the spring arrangement hole 13n. The spring 13j is fixed. The spring fixing portion 13h is pressed against the inner wall surface of the space 13B by receiving a pressing force in the T direction from the spring 13j.

Further, a shaft through hole 13o is formed in the thickness direction at a substantially central portion (substantially central portion on the side where the magnet 13e is disposed) of the spring fixing portion 13h, and a spring is formed in the shaft through hole 13o. The pin 13g penetrates. Both end portions of the spring pin 13g slightly protrude from both end portions of the shaft through hole 13o, and these protruding portions are attached to a lid 13k described later.
Since it is formed in this way, when a force in the T direction is applied to the locking claw 13i and a force in the same direction is applied to the shaft, the spring pin 13g is contracted by this force and the diameter is slightly reduced. For this reason, the latch member 13f rotates slightly in the T direction around the spring pin 13g. When the force applied in the T direction is lost, the spring pin 13g returns to the original shape, and at the same time, the latch member 13f returns to the original position by the urging force of the spring 13j.

A substantially cylindrical groove 13s is formed on the surface opposite to the side where the shaft through hole 13o is formed, and another spring pin (not shown) is provided in the groove 13s. Also good.
In this case, the other spring pins are arranged in the groove 13s and are arranged so that a part of the outer wall surface is in contact with the inner wall surface of the space 13B.
By being arranged in this way, the elastic action of other spring pins can be utilized. That is, the latch member 13f moves by an amount corresponding to the decrease in the diameter of the other spring pin due to the force applied in the T direction, and when the force applied in the T direction disappears, the other spring pin returns to its original shape. The latch member 13f also returns to the original position.

  As shown in FIG. 5, the lid 13k is a substantially concave plate having a shape obtained by cutting out a substantially rectangular plate into a square. Hereinafter, this notched portion is referred to as “latch member disposition space 13p”, and opposing side walls constituting the latch member disposition space 13p are denoted as latch member disposition space side walls 13q and 13q.

As shown in FIG. 5, the latch member 13f is arranged in the latch member arrangement space 13p.
At this time, both end portions of the spring pin 13g are respectively attached to the latch member arrangement space side walls 13q and 13q.
Thus, the lid 13k to which the latch member 13f is attached is disposed in the space 13B and closes the upper portion of the locking space 13l (see FIG. 4).

The case 11, the slider 12, and the magnet main body 13 described above are assembled to form the door embedded member 1.
As shown in FIG. 3, the slider 12 is attached to the magnet body 13.
The slider 12 is disposed so as to cover the magnet body 13 from above. At this time, the shaft protrusions 13c and 13c are slidably fitted into the slider slits 12a and 12a, respectively.

Thus, with the slider 12 attached to the magnet body 13, the magnet body 13 and the slider 12 are disposed inside the cover 11C.
At this time, the shaft protrusions 13c and 13c are attached to the shaft movement holes 11i and 11i of the cover 11C so as to be movable up and down.
Further, both end portions of the slider shaft 12e are fixed to the inner sides of the side walls 11g and 11g of the cover 11C.
Further, the adjusting bolt 20 as a moving member is attached to the adjusting bolt through hole 12c and the adjusting bolt receiving nut 12d formed in the slider 12 through the adjusting bolt hole 11b and the bolt hole 11d.
The operation and action of the adjusting bolt 20 will be described later.

In this way, the slider 12 is attached so as to be horizontally movable, and the magnet body 13 is attached so as to be movable up and down.
The case 11 is attached to the inside of the door R by screws 40 and 50.

Next, the floor mounting member 2 will be described.
As shown in FIG. 8, the floor mounting member 2 according to the present embodiment mainly includes a covering member 21 and a main body 22.
The covering member 21 is a substantially disk-shaped lid-like member, and covers a main body 22 described later from above.
A substantially T-shaped member exposure hole 21 a is formed at a substantially central portion of the covering member 21.
The member exposure hole 21a is a hole for exposing a locked member 22B and a locked member fixing portion 22C, which will be described later, and the locked member 22B and the locked member fixing portion 22C are disposed on the plate 22A. It is formed at a position that matches the position.

The main body 22 according to the present embodiment mainly includes a plate 22A as a support member, a locked member 22B as a locked member, and a locked member fixing portion 22C.
As shown in FIG. 9, the plate 22 </ b> A is a substantially rectangular plate body, and both ends of one long side are cut out into a substantially square shape, and a locked member fixing portion arrangement portion 22 a is formed.

Further, a substantially rectangular locked member disposing hole 22b is formed in a substantially central portion of the plate 22A.
This locked member arrangement hole 22b corresponds to a storage hole.
The to-be-latched member arrangement hole 22b has substantially the same shape as that of a to-be-latched member 22B, which will be described later, and its area is slightly larger than the area of the to-be-latched member 22B.
Loose holes 22c and 22c and screw holes 22d and 22d are formed on both sides of the locked member disposing hole 22b substantially symmetrically with respect to the locked member disposing hole 22b. The screw holes 22d and 22d are perforated on the locked member fixing portion arrangement portion 22a side.

The locked member 22B is a substantially rectangular plate whose both ends in the longitudinal direction are bent in the same direction.
A shaft through hole 22e is formed in one of the bent portions, and a shaft 22f passes through the shaft through hole 22e. Both ends of the shaft 22f slightly protrude outward from the shaft through hole 22e.
The locked member 22B is formed of a magnetic metal.
The end portion on the side where the shaft through hole 22e is not formed is referred to as a “locked portion 22g”.

The locked member fixing portion 22C is a member having a substantially L-shaped cross section, and includes a locked member fixing portion 22h and a plate fixing portion that stands substantially vertically from one long side of the locked member fixing portion 22h. 22i.
One long side of the locked member fixing portion 22h (long side on the side where the plate fixing portion 22i is not formed) is cut out in a substantially rectangular shape. This notch is referred to as a “locked member disposition portion 22j”.
Of the three surfaces constituting the locked member disposing portion 22j, shaft mounting holes for rotatably mounting the shaft 22f disposed on the locked member 22B on opposite side walls 22k and 22k. 22l and 22l are formed.

The main body 22 is formed by assembling the plate 22A, the locked member 22B, and the locked member fixing portion 22C thus formed.
The locked member 22B is disposed in the locked member fixing portion 22C by rotatably attaching both ends of the shaft 22f to shaft mounting holes 22l and 22l formed in the locked member fixing portion 22C. The
The locked member fixing portion 22C on which the locked member 22B is arranged is attached to the locked member fixing portion arranging portion 22a of the plate 22A.

In other words, the locked member fixing portion 22C is attached to the plate 22A by mounting the plate fixing portion 22i formed in the locked member fixing portion 22C on the free end side of the locked member fixing portion arrangement portion 22a. It is done. At this time, the locked member 22B is disposed at a position aligned with the locked member disposing hole 22b.
The locked member fixing portion 22 </ b> C formed in this way is attached to a predetermined position on the floor surface with a bolt, and then the upper surface side is covered with the covering member 21.
Further, as shown in FIG. 10B, the locked member 22B is configured to rotate in the direction of the arrow about the shaft 22f.

As described above, since the floor mounting member 2 according to the present embodiment is a part for supporting and storing the locked member 22B, the height is equal to the thickness of the locked member 22B and the covering member 21. Is approximately equal to the sum of the thicknesses. Since the thickness of the locked member 22B and the thickness of the covering member 21 are very small, the height of the floor mounting member 2 according to this embodiment is about 3 mm.
For this reason, compared with the conventional product in which the height of the parts attached to the floor is about 8.5 mm, the height is less than half and becomes almost flat with the floor surface.
Therefore, there is no need for people to crawl and it does not interfere with cleaning. Moreover, it can be used even within the movable range of the storage door.
Furthermore, since it does not protrude from the floor surface, it is advantageous in terms of design.

A method of holding the door R in a predetermined position using the door burying member 1 and the floor mounting member 2 configured as described above will be described.
When the door R to which the door burying member 1 is attached is close to the floor mounting member 2 and the locked member 22B of the floor mounting member 2 enters the magnetic field of the magnet 13e, the locked member 22B that is a magnetic body. Is attracted by the magnetic force of the magnet 13e.

Since the locked member 22B is configured to rise with the shaft 22f as a rotation center, the locked member 22B is raised by the magnetic force of the magnet 13e, guided to the locking space 13l, and locked to the locking claw 13i of the latch member 13f. The
Thus, FIG. 11 shows an explanatory diagram of the state in which the locked member 22B is locked to the locking claw 13i.
As shown in FIG. 11, the locked portion 22g of the locked member 22B attracted by the magnet 13e and guided to the locking space 13l is locked to the locking claw 13i.

That is, when the door R moves in the opening direction, the locking member 22B that has entered the magnetic field of the magnet 13e is attracted by the magnetic force of the magnet 13e and rises upward, and the locked portion 22g is engaged with the locking claw 13i. Contact the free end. At this time, a force in the T direction is applied to the locking claw 13i.
As described in the description of the latch member 13f, the locking claw 13i that has received a force in the T direction by the locked portion 22g slightly rotates in the same direction, whereby the locked portion 22g is locked. Enter the space 13l. Further, when the locked portion 22g enters the locking space 13l, the force applied in the T direction is released, so that the latch member 13f returns to the original position, and the locking claw 13i holds the locked portion. 22g will be held reliably.
Further, when the door R moves in the closing direction (the direction opposite to the opening direction), the locked state is released by the force applied to move the door in the closing direction, and the locked portion 22g is connected to the magnet 13e. Since it is out of the magnetic field range, the locked portion 22g returns to the original position (in the locked member disposing hole 22b).

Next, the vertical movement mechanism of the magnet body 13 will be described with reference to FIG.
The adjusting bolt 20 as a moving member is composed of a main body 20a and a washer 20b which are known bolts, and the washer 20b is fixed to the back surface of the head of the main body 20a.
The adjustment bolt 20 passes through the adjustment bolt hole 11b, the washer 20b, the adjustment bolt through wall 12B, and the adjustment bolt receiving nut 12d. A part of the washer 20b is inserted into the washer slit 11k. For this reason, the washer 20b rotates in the same direction as the rotation direction of the adjustment bolt 20, but does not move in a direction substantially perpendicular to the rotation surface. In order to reliably prevent the washer 20b from moving in a direction substantially perpendicular to the rotation surface, a movement blocking member or the like may be further provided, or a slit may be further provided on the lower side of the washer slit 11k. Good.

In the state of Fig.12 (a), the magnet main body 13 is located in the uppermost part.
In this state, when the adjustment bolt 20 is rotated in the direction B, the washer 20b is fixed to the main body 20a, and the adjustment bolt receiving nut 12d is fixed to the adjustment bolt through wall 12B. It cannot move in a direction substantially perpendicular to the moving surface, and the distance x between the washer 20b and the adjusting bolt receiving nut 12d is increased.
As described above, since the slider 12 is configured to be movable in the horizontal direction, the slider 12 moves in the direction of B.
That is, since the slider shaft 12e receives a force in the horizontal direction, the diameter of the slider shaft 12e is slightly reduced (by the width of the slit of the spring pin), so that the slider 12 moves along the shaft moving holes 12b and 12b. It can move in the horizontal direction.

At this time, since the magnet body 13 is configured to perform only vertical movement, the magnet body shaft 13b descends along the shaft moving holes 12b and 12b.
As described above, when the adjustment bolt 20 is rotated in the direction B, the distance x between the washer 20b and the adjustment bolt receiving nut 12d is increased and the magnet body 13 is lowered.

FIG. 12 (b) shows a lowered state.
When the adjustment bolt 20 is rotated in the direction opposite to the direction B in this lowered state, the distance x between the washer 20b and the adjustment bolt receiving nut 12d is reduced, and at the same time, the magnet body 13 is raised.
Thus, the magnet main body 13 according to the present embodiment is movable in the vertical direction.
For this reason, even if the distance between the lower surface of the door R and the floor is slightly different, it is possible to cope by adjusting the position of the magnet body 13.

Normally, in a magnet type door stopper, due to the restriction that the magnetic field of the magnet is constant and the size of the member for holding the door is constant, there is a difference between the member attached to the door and the member attached to the floor. If the distance exceeds a certain distance, it will not function. For this reason, it is necessary to prepare door stoppers having different sizes of members for holding the doors and different types of magnets (magnet magnetic force) depending on the distance between the lower surface of the door and the floor surface.
However, the door stopper S according to the present embodiment can adjust the position of the magnet main body 13, and therefore can cope with a slightly different distance between the lower surface of the door R and the floor.

Next, a method for mounting the floor mounting member 2 according to the present embodiment will be described with reference to FIGS.
As shown in FIG. 13, the door R is disposed at a position where the door R is desired to be held, and the main body 22 of the floor mounting member 2 is disposed below the magnet main body 13.
When the reference position is determined, screws 60, 60 are inserted from the loose holes 22c, 22c, and the main body 22 is temporarily fixed to the floor.

Next, the center point P marked on the magnet main body 13 and the center line of the main body 22 are aligned, and when the arrangement position of the main body 22 is determined, as shown in FIG. To fix the main body 22 to the floor.
Next, the distance between the bottom surface of the magnet body 13 and the body 22 is adjusted.

As shown in FIG. 15, the locked member 22B is guided into the magnet body 13 and the magnet body 13 is lowered to a position where it is locked by the latch member 13f.
This operation is performed by turning the adjustment bolt 20 disposed in the adjustment bolt hole 11b to the left using a tool such as a screwdriver.
As described above, by rotating the adjustment bolt 20 to the left, the slider 12 moves in the horizontal direction, and the magnet body 13 descends as the slider 12 moves.
When the distance adjustment is completed, as shown in FIG. 16, the covering member 21 is put on the main body 22 from above.
If the covering member 21 is of the same color as the floor, or the same pattern and the same material as the floor, the floor mounting member 2 is inconspicuous, which is advantageous in terms of design.

In the present embodiment, since the door burying member 1 is embedded in the door R, the door burying member 1 does not protrude to the outside, there is no need to hit a leg, and the design is advantageous.
Moreover, since the door burying member 1 does not protrude outside the door R, it can be used together with the door bottom.
Further, since the floor mounting member 2 is only for supporting the locked member 22B, the height can be considerably reduced as compared with a conventional product in which a magnet or the like is mounted on the floor side.
For this reason, even if the floor mounting member 2 is mounted on the floor, the floor mounting member 2 is almost flat and does not obstruct cleaning, which is advantageous in terms of design.
Moreover, in this embodiment, the magnet main body 13 which comprises the door embedding member 1 can be moved up and down.
For this reason, even when the distance between the lower surface of the door R and the floor is different, the door stopper S according to the present embodiment can be used by adjusting the position of the magnet body 13.
