Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door that slides along a groove or a rail to open and close.

[0002]

2. Description of the Related Art Sliding doors are widely used as fittings (including those used as partitions between openings), and are also attached to openings as sliding doors that close the openings of furniture and closet doors. It is used.

[0003]

In the conventional sliding door, when the sliding door is closed vigorously, the sliding door body rebounds due to the reaction against the vertical frame of the sliding door frame, and a gap is formed between the sliding door body and the vertical frame, resulting in hermeticity. Was sometimes damaged.

For this reason, a stopper such as a leaf spring is attached to the sliding door rail on which the sliding door main body travels, and the sliding door is pressed by the stopper to decelerate the speed, whereby the sliding door main body is stopped near the vertical frame.

However, since the conventional sliding door stopper decelerates and stops the sliding door by the frictional force generated by pressing the sliding door, it is difficult to adjust the pressing force of the stopper against the sliding door.

Further, since the traveling speed when closing the sliding door is not constant, it is practically impossible to always close the sliding door main body in close contact with the vertical frame even if the pressing force of the stopper is strictly adjusted below. It was possible.

[0007]

And a frame. The sliding door bodies 1 and 1 are opened and closed by sliding in the sliding door frame. To enable this sliding, a rail is attached to the upper frame of the sliding door frame and the rails are attached to the upper ends of the sliding door bodies 1 and 1. Depending on the need, there may be an upper suspension system in which a suspension car traveling along the rail is attached, or a door system in which a rail is attached to the lower frame of the sliding door frame and at the lower end of the sliding door main bodies 1 and 1 are mounted a door roller traveling along the rail. Will be adopted. Since these methods are all known, they are omitted in the drawing.

The sliding door bodies 1 and 1 are made of solid wood, plywood, wood fiberboard, particle board, etc.
A wood-based material such as a single plate laminated material (LVL) can be manufactured by framing or flashing. Alternatively, a synthetic resin may be molded to form the sliding door bodies 1, 1. Arbitrary makeup on the surface can be applied by painting or sticking a veneer / decorative sheet or the like.

It can be manufactured from a wood-based material such as a single plate laminated material (LVL) or by molding a synthetic resin.
The surface thereof may be applied with arbitrary makeup such as painting or sticking a veneer / decorative sheet.

On the vertical side surfaces where the sliding door bodies 1 and 1 and the vertical frames 2 and 2 are in contact with each other when closed, a magnet 3 is provided on one side, and on the other side, a metal piece or another magnet attracted to the magnet by magnetic force. 4 are provided. That is, the sliding door bodies 1 and 1 and the vertical frames 2 and 2 are closed in close contact with each other by attraction of the magnets or attraction of the metal and the metal piece.

The magnet may be steel with a magnetic force commonly used as a magnet. Alternatively, a soft magnet manufactured by mixing magnetic steel powder with a synthetic resin may be used.

Any metal piece may be used as long as it has a property of being attracted to a magnet by magnetic force, and iron, a part of stainless steel or the like is generally used, or an electromagnet may be used.

These magnets or metal pieces allow the magnetic force of the magnet to sufficiently extend to the other vertical side surface, and in the case of a metal piece, can sufficiently receive the magnetic force of the magnet provided on the other side. Each must be installed. From this point of view, in general, the magnet or the metal piece is directly fixed to the vertical side surfaces where the sliding door bodies 1 and 1 and the vertical frames 2 and 2 are in contact with each other when closed, or as shown in FIG.
The magnet or metal piece is embedded and fixed in a hole formed in the vertical side surface such that the surface of the magnet or the metal piece is exposed substantially flush with the surface of the vertical side surface.

However, as long as the condition that the magnetic force of the magnet is sufficiently extended to the other vertical side surface and the metal piece can sufficiently receive the magnetic force of the other magnet, as shown in FIG. An optional makeup 5 such as painting or sticking a veneer / decorative sheet can be applied so as to cover the vertical side surface where the magnet / metal piece is fixed or embedded. For example, by applying the makeup 5 that matches the color tone with other portions, it is possible to avoid deterioration in designability due to exposure of the magnet / metal piece.

FIG. 2 shows an embodiment in which the magnet / metal piece 3 is embedded in the vertical side surface of the sliding door body 1 and the makeup 5 is applied to the vertical side surface. It goes without saying that it may be provided on the side of.

As long as the magnets / metal pieces 3 and 4 can close the sliding door bodies 1 and 1 and the vertical frames 2 and 2 in close contact with each other by their mutual adsorption action, their mounting manners and mounting locations are It can be set arbitrarily. For example, the magnets / metal pieces 3 and 4 may be continuously provided over the entire length of the vertical side surfaces of the sliding door body 1 and the vertical frame 2, or a plurality of magnets / metal pieces may be provided at predetermined intervals. Further, also in the width direction, it can be provided over the entire width of the vertical side surfaces of the sliding door body 1 and the vertical frame 2, or can be provided only at the necessary portions thereof, for example, only the central portion in the width direction or both end portions.

Further, as shown in FIG. 3, there is provided a door slide 6 into which the vertical side end portions of the sliding door bodies 1 and 1 are fitted over the entire length of the vertical frames 2 and 2, and a magnet / The metal piece 4 can be fixed or embedded. The door flap 6 is formed according to the shape and size of the sliding door body 1 to be fitted, and has a trapezoidal cross section that is narrower from the entrance portion to the bottom surface in addition to the rectangular cross section as shown in FIG. It may be formed in a shape.

Also in this case, of course, as long as the adsorbing action of the magnet / metal piece 4 provided on the bottom surface of the door flap 6 is not impaired, the makeup 5 for covering the surface can be provided (see FIG. 2). .

The magnet / metal piece 4 can be attached to the bottom surface of the door flap 6 at an arbitrary position, and is provided continuously or at intervals in the lengthwise direction,
Further, in the width direction, it may be provided continuously over the entire width or only in predetermined portions such as the center portion and both end portions in the width direction.

In this manner, when the door frame 6 into which the vertical end of the sliding door body 1 is fitted is formed in the vertical frame 2 and the magnet / metal piece 4 is provided on the bottom surface thereof, the magnetic force of the magnet changes with time. However, even if the sliding door body 1 and the vertical frame 2 cannot be closed tightly without a gap, the vertical side end of the sliding door body 1 is housed in the door slide 6. ,
A closed state with substantially no gap can be obtained, and the entry of draft air can be prevented.

When the door frame 6 is provided on the vertical frame 2, the vertical side end of the sliding door body 1 fitted in the door frame 6 should be chamfered or formed into a curved surface. Is preferred. As a result, the side end portion of the sliding door body 1 is a door slide 6
When it is fitted into the
Particularly, when the surface makeup is applied, the makeup can be prevented from peeling off and the appearance can be maintained for a long time.

As described above, in the sliding door structure of the present invention, the vertical side surfaces of the sliding door body 1 and the vertical frame 2 are brought into close contact with each other without a gap by the mutual attraction between the magnets or between the magnet and the metal piece to close them. However, it is preferable to provide a means for releasing the closed state fixed by the magnetic force to easily open the sliding door body 1.

For example, as shown in FIG. 4, the sliding door body 1 on the side in contact with the vertical frame 2 (the side on which the magnet / metal piece 3 is provided).
One or a plurality of pins 7 are provided at arbitrary locations on the vertical side surface of the door so that they can be projected / retracted from the vertical side surface, and a puller 8 for operating the withdrawal operation of the pin 7 in conjunction with opening / closing of the sliding door body 1.
Are provided on the front and back of the sliding door body 1.

FIG. 4 shows the positions of the pin 7 and the pull tab 8 when closed. From this state, hold the pull tab 8 and slide the door body 1
When a force is applied in the opening direction A, the pin 7 projects in the opposite direction B, and pulls the sliding door body 1 away from the vertical frame 2 against the magnetic force or the attraction force between the magnets or between the magnet and the metal piece. Act on. When the pull tab 8 is released, the pin 7 returns to the buried position shown in FIG. 4 by the force of a spring (not shown).
When the sliding door body 1 is closed, no force is applied to the pull tab 8, so that the pin 7 is held in the buried position and does not hinder the attraction by the magnets / metal pieces 3, 4.

Further, a magnet provided on the vertical side surface of the sliding door main body 1
The metal piece 3 itself can be linked so as to retract from the vertical side surface by the operation of opening the pull tab. In this case, when the sliding door body 1 is opened, the force applied to the pull tab causes the magnet / metal piece 3 to be buried and retracted from the vertical side surface, whereby the magnet / metal piece 3 is moved between the magnet / metal piece 4 on the vertical frame 2 side. The suction force of the sliding door is reduced, and the sliding door body 1 can be opened with a slight force.

Alternatively, a magnet 3 having an N pole or an S pole is provided on the vertical side surface of the sliding door body 1 and a magnet 4 having an S pole or an N pole is provided on the vertical side surface of the vertical frame 2 so as to interlock with the puller. When the sliding door body 1 is opened, the magnetism of the magnet 3 on the sliding door body 1 side may be reversed to repel the magnet 4 on the vertical frame 2 side.

Alternatively, the electromagnet 3 may be provided on the sliding door body 1 side, and the electric current flowing through the electromagnet 3 may be cut when a pull tab is pulled in the direction of opening the sliding door body 1.

In addition, any mechanical or electrical means can be adopted to facilitate the work of opening the sliding door body from the fixed state by the magnetic force at the time of closing.
