Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for swinging and fixing a sliding door of a type that can be hung just below a rail and run under the rail.

[0002]

2. Description of the Related Art Sliding doors of the type that can be hung just below a rail and run underneath are well known in the prior art, not to mention an example.

[0003]

In this type of sliding door, since the door is in a suspended state, even if the door is just closed, the door can be moved in either the left or right direction with respect to the frame of the other party. A situation of swinging can occur. In particular, this swing is greater on the lower side of the door. This is because the upper side of the door is hung on the rails, and the lower side is more likely to swing. An object of the present invention is to provide a mechanism capable of fixing a closed door and a frame body without causing such a situation in a hanging type sliding door.

[0004]

In order to achieve this object, according to the present invention, one of a door 1 and a frame 2 of a sliding door A of a type that can be hung just below a rail and run under the rail, The magnet 3 that can be projected and retracted from the end face is arranged, and the attraction plate 4 is arranged on the other side. When the end face of the door 1 approaches the end face of the opponent frame body 2 as shown in FIG. 1 or 3 as the door 1 is closed, the magnets 3 arranged on one of the door 1 and the frame body 2 Is attracted to the side of the suction plate 4 on the other side and projects from the end face thereof, and the door 1 is fixed to the frame body 2 by the suction force.
Therefore, the door 1 can be prevented from swinging to the left or right with respect to the frame body 2 with a very simple mechanism. Also, the magnet 3
By the suction action of the suction plate 4 and the suction plate 4, the closed door 1 and the frame body 2 can be firmly fixed.

As shown in FIG. 1, the installation position of the magnet 3 and the attraction plate 4 is as low as possible between the door 1 and the frame 2 so that the steadying effect is large. This is because the upper side of the door 1 is hung on the rail and the lower side is more likely to swing, and the effect of the steady rest becomes greater when the magnet 3 and the attraction plate 4 are installed on the lower side where swinging is easier. Is. However,
It does not necessarily have to be on the lower side. For example, as shown in FIG. 3, if the door 1 and the frame body 2 are arranged substantially in the middle, a fixing function is exerted rather than a steady rest.

In a state where the end surface of the door 1 is in contact with the end surface of the frame body 2, the magnet 3 protruding from either one of the end surfaces of the door 1 and the frame body 2, or a magnet holder holding the magnet 3
Between the end face of 3a and the end face of the suction plate 4 arranged on the other side,
It is preferable to install the both so that a slight gap C is formed. With this configuration, when the door 1 is closed, the magnet 3 arranged on either one of the door 1 and the frame body 2 or the magnet holder 3a holding the magnet 3 does not directly contact the attraction plate 4. There is no collision sound generated when the cars directly collide.

In the above case, it is preferable that the screw hole 6a of the end surface fitting 2a for attaching the suction plate 4 be a long hole which is long in the lateral direction. By doing so, as shown in FIGS. 5 (a) to 5 (c), the end surface fittings 2a can be displaced to the left and right so that the tightening position of the screw 6 is located at one of the long holes in the lateral direction. Therefore, the attracting position of the magnet 3 with respect to the attracting plate 4 can be easily adjusted.

In the above case, it is preferable that the hole 2b facing the suction plate 4 is a long hole which is long in the vertical direction. By doing so, even when the hanging type sliding door A is adjusted in the vertical direction, the magnet 3 has the above-mentioned hole that is long in the vertical direction.
Since it is inserted in any position of 2b, it is possible to easily cope with the vertical adjustment of the door 1.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION
It will be described in detail with reference to the drawings. FIG. 1 shows an example of the hanging sliding door of the present invention. Although illustration of the installation state of the sliding door A is omitted, a so-called top-hanging type sliding door, that is, a trochanter of the runner of the hanging member embedded in the upper end portion of the sliding door A and extended upward from the end surface thereof. It is adapted to be fitted in a groove of a rail installed on the ceiling side indoors and hung so that it can run under the rail. 1 and 3, for convenience, the state immediately before the door 1 is completely closed is shown. Therefore, in FIGS. 1 and 3, the door 1 is not in contact with the frame body 2.

This hanging type sliding door A is equipped with a mechanism for enabling steadying and fixing. This mechanism is composed of a magnet 3 which is arranged on either one of the sliding door 1 and the frame 2 and which can be retracted from the end face thereof, and an attraction plate 4 which is arranged on the other side. Door 1 in the drawing
The case where the magnet 3 is arranged on the side and the attraction plate 4 is arranged on the side of the frame 2 which is the other side is illustrated. As shown in detail in FIG. 4, the magnet 3 is housed in a magnet holder 3a that can slide in a recess 1b located at the back of the end surface fitting 1a attached to the end surface of the door 1, and its front end The surface (the left end surface in the figure) faces the hole 3b of the magnet holder 3a. A coil-shaped spring 5 is interposed between the front end surface (left end surface in the figure) of the magnet holder 3a and the inner end surface (left end surface in the figure) of the end surface fitting 1a.
On the other hand, as shown in detail in FIG. 4, the suction plate 4 arranged on the side of the frame body 2 is embedded in the end face fitting 2a attached to the end face of the frame body 2, and its front end face (in the figure). (Right end face)
Is exposed from the hole 2b of the end fitting 2a.

As the door 1 is closed, its end face is shown in FIG.
Further, as shown in FIG. 3, when approaching the end face of the frame 2 on the other side, the magnet 3 arranged on the door 1 side becomes a coiled spring 5.
Against the elastic force of the magnet holder 3a, the magnet holder 3a and the magnet holder 3a are attracted to the attracting plate 4 side of the frame 2 which is the other side, and as shown in detail in FIG. Then, at that time, the door 1 is fixed to the frame body 2 by the attracting force of the magnet 3, and the door 1 can be prevented from swinging to the left or right with respect to the frame body 2. In addition, the closed door 1 and the frame body 2 can be firmly fixed by the attraction between the magnet 3 and the attraction plate 4.

Here, the case where the magnet 3 is arranged on the side of the door 1 and the attraction plate 4 is arranged on the side of the frame body 2 which is the other side is illustrated, but the mounting positions of both are reversed, that is, the magnets are arranged. 3 for frame 2
, The suction plate 4 may be arranged on the door 1 side. Further, as shown in FIG. 1, the installation position of the magnet 3 and the attraction plate 4 is as low as possible between the door 1 and the frame body 2, so that the steadying effect is large. This is because the upper side of the door 1 is hung on the rail and the lower side is more likely to swing, and the effect of the steady rest becomes greater when the magnet 3 and the attraction plate 4 are installed on the lower side where swinging is easier. Is. However, it does not necessarily have to be on the lower side. For example, as shown in FIG. 3, if the door 1 and the frame body 2 are arranged at a substantially intermediate position in the vertical direction, a fixing function is exerted rather than a steady rest. .

When the end surface of the door 1 is in contact with the end surface of the frame body 2, that is, when the door 1 is closed, the door 1
End surface of the magnet 3 protruding from the end surface fitting 1a attached to the end surface of the frame 3, more specifically, the end surface of the magnet holder 3a holding the magnet 3, and the end surface attached to the end surface of the frame body 2. Between the end face of the suction plate 4 located in the metal fitting 2a,
Both of them (the magnet 3 and the attraction plate 4) may be installed so that a slight gap indicated by a reference symbol C in FIG. With this configuration, when the door 1 is closed, the end surface of the magnet 3 arranged on the door 1 side is attracted to the end surface of the attraction plate 4, more specifically, the end surface of the magnet holder 3a holding the magnet 3 is attracted. Since the end face of the plate 4 does not directly hit, the collision sound generated when the two directly collide does not occur. The gap C can be set to about 1 mm, for example.

End surface fitting 2a to which the suction plate 4 is attached
5 is attached to the end surface of the frame body 2 by the upper and lower two screws 6 and 6 as shown in FIG. 5, but if the screw holes 6a and 6a are elongated holes in the lateral direction as shown in FIG. Good. By doing so, as shown in FIGS. 5 (a) to 5 (c), the screw 6
Since the end surface metal fitting 2a can be shifted to the left and right so that the tightening position of is located at one of the positions of the long hole in the lateral direction,
The attraction position of the magnet 3 with respect to the attraction plate 4 can be adjusted. Figure 5
(a) shows the case where the tightening position of the screw 6 is at the center of the screw hole 6a that is long in the lateral direction, and Fig. 5 (b) shows that the tightening position of the screw 6 is at the right end of the screw hole 6a that is long in the lateral direction. FIG. 5 (c) shows the case where the tightening position of the screw 6 comes to the left end of the screw hole 6a that is long in the lateral direction.

Further, as shown in FIG. 5, it is preferable that the hole 2b of the end surface fitting 2a facing the suction plate 4 is a long hole which is long in the vertical direction. By doing so, even when the hanging type sliding door A is adjusted in the vertical direction, the magnet 3 is inserted into any position of the hole 2b which is long in the vertical direction, and the door 1 is attracted by the attracting force. It is fixed to the frame body 2. Therefore, it is possible to easily adjust the door 1 in the vertical direction without changing the mounting position of the end surface fitting 2a mounted on the end surface of the frame body 2.

The hanging sliding door A illustrated here
1, a box-shaped case 7 is embedded in the end face side (the left end side in FIGS. 1 to 4) which is a substantially middle position in the vertical direction of the door 1, and as shown in FIGS. A hook member 8 which is a sickle-shaped lock having a substantially L-shaped bent portion is rotatably arranged around an axis. Further, a concave portion 2c is formed at an end portion which is a substantially middle position in the vertical direction on the frame body 2 side. Then, the base end side of the hook member 8 and the concave portion of the frame body 2
In 2c, a magnet 8a and a magnet 2d, which are magnetically repulsive to each other, are arranged so that their respective surfaces face each other.

Accordingly, when the end face of the door 1 approaches the end face of the counterpart frame 2 as shown in FIGS. 1 and 3, as the door 1 is closed, the magnets arranged at the end of the door 1 side. 8a and the magnet 2d arranged at the end of the frame 2 magnetically repel each other, and the hook member 8 rotates in the counterclockwise direction around the shaft as shown in FIG. The bent portion protrudes from the end surface of the door 1, and as shown in the figure, the bent portion passes through the opening hole of the end surface fitting 2a attached to the end surface of the frame body 2 and is hooked in the back of the end surface fitting 2a. It can be locked. In this case, the magnet 8a
The suction member 9 positioned within the rotation range on the base side of the hook member 8 is sucked, and the hook member 8 is held in the state of FIG. 2 and the locked state is maintained.

On the contrary, as the door 1 is opened, the tip of the hook member 8 arranged on the door 1 side gradually extends from the inner side of the opening hole of the end face metal fitting 2a attached to the end face of the frame body 2. By this disengagement and this movement of the hook member 8, the door 1 can be opened.
Further, due to this movement of the hook member 8, the attraction state between the magnet 8a and the attraction member 9 is released, and the hook member 8 is held at a predetermined unlocked position.

This type of lock is usually attached to the door 1 side at a substantially middle position in the vertical direction. Then, the steady rest / fixing mechanism described above and the sickle-shaped lock may be used together, or only the steady rest / fixing mechanism described above may be used alone. Even when the above-described steady rest / fixing mechanism and the lock are used together (in the case of FIGS. 1 and 2), it is better to position the steady rest / fixing mechanism below the lock. The reason why this steady rest / fixing mechanism should be located as low as possible and the effect in that case have already been described.

On the other hand, even when only the steady rest / fixing mechanism described above is used alone (FIG. 3), it may be positioned as low as possible between the door 1 and the frame 2. However, it does not necessarily have to be on the lower side. For example, as shown in FIG.
If the steady / fixing mechanism is placed at the position where it is originally attached, that is, at a position approximately midway between the door 1 and the frame 2 in the vertical direction, without attaching the sickle-shaped lock, it will be fixed rather than steady. Exert function.
