DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a hinged door, a folding door,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-sway device used for a door such as a sliding door having a free end lower than the free end of the door when the door is at a closed position.

[0002]

2. Description of the Related Art When the door is in a closed position, the free end of the door is free in the inward and outward directions, that is, a folding door in which the free end of the door is not guided by a general hinged door or a guide rail on the floor side. In doors, sliding doors, etc., when these doors are in the closed limit position, to prevent the lower free end of the door from swinging inward, the lower end of the free end of the door should be moved from the floor or the side of the opening frame. Protrusions may be provided so as to be in contact with the back side. However, when the door is opened, the protrusions remain in a state protruding from the floor surface or the like, which hinders safe traffic and taking in and out of objects.

In order to solve such a problem, an engaging groove in the sliding door moving direction is provided on the bottom surface at the lower end of the sliding door,
When the sliding door is at the closing limit position, a pin that can be raised and lowered is provided on the floor surface so as to be located directly below the engaged groove, and at least an upper end of the pin and a ceiling surface of the engaged groove are provided. A magnet is provided on one side and a surface to be attracted is provided on the other side. When the door reaches the closing limit position, the pin is pulled up from under the floor by the magnetic attraction force between the magnet and the surface to be attracted, and the door is lifted. A door sway device configured to engage in a side groove was contemplated.

[0004]

In the above-mentioned conventional steady rest device for a sliding door, the vertical gap between the magnet before being attracted and the attracted surface is equal to the ceiling surface of the engaged groove on the door side. The relatively large and powerful magnets can be created by the fact that the distance between the upper and lower surfaces of the pins buried under the floor is equal to and greater than the height of the pins (pin lifting stroke), and the total weight of the pins must be increased. Since it is necessary and the weight of the pin must be reduced, the strength of the pin and, in turn, the strength of the door in preventing the swing of the pin may be reduced. Further, a relatively deep pin is provided under the floor so that a relatively long pin, which is sufficiently longer than the distance from the floor to the ceiling surface of the engaged groove on the door side, can be buried under the floor. Such as having to form a storage hole,
There were many problems for practical use.

The base 1 on the floor 2 side is provided with an engaging member 1
The two free ends are attached to the closing door 23 in the direction facing each other. The permanent magnet 26 of the engaged member 18
When the door 23 reaches the closing limit position as shown in FIG. The engaging member 12 is pulled up around the support shaft 15 and rotated,
The concave portion 30 (through circular hole) of the engaging member 12 is fitted to the conical projection 31 on the door 23 side, and the tip of the engaging member 12 is engaged with the corner-shaped engaged portion 25 on the door 23 side. Combine. In other words, the base 1 is fixed at a predetermined position on the floor 2 in the front-rear direction in the above-described direction so as to be in such a state, and the engaged member 18 is Is adjusted in the vertical direction and fixed.

According to the above configuration, when the door 23 is open, the engaging member 12 on the floor surface 2 falls down horizontally by gravity as shown in FIG. It is in contact with and supported on the joint member support portion 8, and is in a state where the concave portion 6 is closed. In such a state, when the door 23 to be closed reaches just before the closing limit position and the permanent magnet 26 on the door 23 is located above the free end of the engaging member 12 on the floor surface 2 side, the permanent magnet 26 is engaged with the door. When the engaging member 12 is lifted by the magnetic attraction force acting between the joining member 12 (the surface to be attracted) and rotated upward around the support shaft 15, and the door 23 reaches the closed limit position. As shown in FIG. 2, a concave portion 30 (a circular through-hole) of the engaging member 12 which is pulled up by the magnetic attraction force and is in an inclined position.
Are fitted into the conical projection 31 on the door 23 side, and the tip of the engaging member 12 is
Will be engaged.

Therefore, the movement of the door 23 which has reached the closing limit position further inward beyond the closing limit position is caused by the tip of the engaging member 12 in the inclined posture on the floor 2 side and the entrance corner on the door 23 side. It is prevented by striking with the engaged portion 25. Further, the swinging movement of the door 23 in the opening movement direction is caused by the resistance provided by the fitting between the concave portion 30 (through circular hole) of the engaging member 12 in the inclined posture on the floor surface 2 side and the conical projection 31 on the door 23 side. Is prevented by Recess 30 (through circular hole)
When the door 23 is forcibly opened by an operation force larger than the resistance force due to the fitting of the conical projection 31 on the side of the door 23 with
By pushing down the engaging member 12 against the side of the conical projection 31 against the magnetic attraction force, the concave portion 3 of the engaging member 12 is pressed.

Of the movable projection 31 on the door 23 side with the spring 33
While pushing up against the urging force of the engaging member 18, enters the space 36 between the inclined bottom surface 24 of the engaged member 18 and the stopper 35, and when the leading end is engaged with the corner engaged portion 25, the spring The movable projection 31 that protrudes downward by the urging force of 33 is fitted into the concave portion (through circular hole) 30 on the engaging member 12 side. Therefore, the action of preventing the door 23 at the close limit position from moving inward beyond the close limit position by the engaging member 12 in the inclined posture is the same as that of the previous embodiment, When the door 23 is opened, the resistance acting on the door 23 is greater than that of the previous embodiment because the movable projection 31 must be pushed up against the urging force of the spring 33. In other words, the door 2 in the closing position
The function of preventing the third member from swinging outward is enhanced.

The device of the present invention can be used not only as a swing door (single swing door, double swing door, etc.) as described in the above embodiment, but also as a swing-stopping device for a folding door or a sliding door. In the case of a folding door or a sliding door, the opening and closing movement direction in the vicinity of the closing limit is substantially orthogonal to the opening and closing movement direction in the vicinity of the opening limit of the opening door, and thus the width direction of the engaging member 12 on the floor surface 2 side. Only the difference is that the engaged member 18 on the door side moves closer to and away from the door.
This is the same in that it is prevented by the tension of No. 2 and swinging outward is prevented by fitting the concave portion 30 on the engaging member 12 side and the projection 31 on the engaged member 18 side substantially vertically.

The permanent magnet 26 is attached to the engaging member 12 on the floor 2 side, and a magnetic plate is attached to the engaged portion 25 on the door side (for example, the inclined bottom surface 24 of the engaged member 18). It is also possible to attach a permanent magnet to both of them, and to increase the magnetic attraction force acting between them. Further, the engagement member 12 may be provided with a weak spring acting in a direction for returning the engagement member 12 to the lying posture.

Further, a projection 31 is provided so as to project upward from the engaging member 12, and the inclined bottom surface 24 of the engaged member 18 on the door side, for example.
The recess 30 into which the upward projection 31 fits may be provided. Of course, no matter which side is provided, the recess 3
0 may not be a hole penetrating the member in which the concave portion is formed, but may be a depression having a depth to which the projection 31 can fit.
Further, in the second embodiment, instead of the stopper 35 for receiving the tip of the movable projection 31, the movable projection 3
Stopper that regulates the fall of 1 within a certain range
It may be provided on two sides.

Further, a corner-shaped engaged portion, a projection (or a concave portion), and a magnet (or a surface to be attracted) are inserted into the lower end of the free end of the door.
In order to dispose the door, the engaged member 18 is provided on the back side of the lower end of the free end of the door, but the corner-shaped engaged part, the projection (or the concave part), and the magnet (or the attracted surface) are provided. ) Can be directly disposed on the bottom surface of the lower free end of the door, or can be disposed on the engaged member buried in the lower surface of the lower free end of the door.

[0021]

As described above, the door steadying device of the present invention, when the door reaches the closing limit position, pulls up the engaging member in the lying posture on the floor side by magnetic attraction force and turns it to the inclined posture. The closed door can be prevented from swaying inward by the engaging member in the inclined position by engaging the leading end thereof with the entry corner-shaped engaged portion on the door side. As compared with the conventional configuration in which the entire pin-shaped engaging member is vertically pulled up, the magnetic attraction force required to raise the tip of the engaging member by a required stroke is small, and a relatively small magnet can be used. Even if only one of the engaging member and the engaged portion is provided, the engaging portion (the distal end of the engaging member) is securely and strongly raised by a required stroke to engage the engaged portion on the door side. As a result, the desired steadying effect of the lower part of the door end can be obtained. Further, it is not necessary to form a deep hole below the floor surface, and the implementation is easy.

Further, according to the structure of the present invention, in a state where the corner-like engaged portion on the door side is engaged with the tip of the engaging member, the door can be disengaged from each other by the forcibly opening movement of the door in a substantially vertical direction. The recesses and projections that are fitted to each other are provided on the door side and the engagement member side, so that only the door can be prevented from swinging inward from the closed limit position due to the tension of the floor side engagement member. In addition, it is possible to prevent the door from easily swinging outward. That is, it can be utilized as a steady rest device having a catch function for a closed door.

The projection is not limited to the conical projection as shown in the embodiment, as long as it can prevent the closed door from swinging outward.
According to the configuration of claim 2, since there is no restriction on the relative approach / removal direction between the projection and the recess due to opening and closing of the door,
One steady rest device can be used for a hinged door and a folding door or a sliding door. In addition, it is possible to integrally form the projection on the door side or the engagement member side, so that the structure is simple, and it can be implemented easily and inexpensively.

According to the third aspect of the present invention, the magnetic attraction force for pulling up the engaging member is made sufficiently large to engage the engaging member with the corner-shaped engaged portion on the door side. Even if it is configured to be surely performed, when the movable protrusion is pushed up by the engaging member that engages with the corner-shaped engaged portion on the door side, when the concave portion on the engaging member side is located immediately below the protrusion. The two can be fitted by lowering the movable projection. In this case, according to the configuration of the fourth aspect, not only is the structure simplified compared with the case where a stopper for restricting the lowering limit is incorporated on the through hole side where the movable projection is incorporated, but also the fitting of the projection and the concave portion is achieved. The effect of stopping the swinging movement of the door to the outside due to the combination becomes stronger.
