Description

[Detailed description of the invention] The present invention brings at least two doors into a flat closed state by abutting their inner edges against each other in an opening in a door mounting frame of a cabinet, etc., and from this state one side is closed. This is the so-called outset method in which the door is opened by moving one door so that it overlaps with the front or back side of the other door (the door is opened and closed externally on the front end of the opening of the door mounting frame). The present invention relates to flat-close sliding door devices of the type in which the door operates (operating type) or the inset type (the door is placed inside the door mounting frame and operates to open and close).

Conventional general sliding doors create a step between the doors, which detracts from the aesthetics of the design, so the above-mentioned flat-closing sliding doors have begun to be used more frequently. If a gap is not provided between the butting ends, the doors will be piled up and cannot be opened or opened, making it impossible to achieve a completely closed state. There were various problems in use, production, and cost, such as the inability to open and move the device without doing so.

Therefore, in order to solve the above-mentioned problem, two traveling bodies are provided at both the upper and lower ends of the left and right doors, respectively, at the inner and outer ends of the door in the width direction, and these are provided with brackets or the like. One upper wall door rail and one lower wall door rail are provided on each of the upper and lower walls of the door mounting frame so that the door can be guided to open and close when the traveling body is engaged with the door rail. A straight part provided in the center of the door, and a straight part at both left and right ends of the straight part, which can be rotated forward or backward using the running body at the outer edge of the door as a fulcrum to prevent mutual interference when the doors are opened and closed. When the left and right doors are opened and closed, the running body at the inner end of the door engages with the curved inclined part so as to be able to move freely in the front and rear directions of the door to allow the above-mentioned rotation and the mutual sliding movement of the doors. The applicant has already filed an application for a plane closing sliding door device which includes left and right evacuation parts connected to each other in the vicinity of the left and right sides of the straight part so as to be guided.

According to the above-mentioned door device, the two running bodies provided in the width direction of the door provide stable support for the door, allow for a large opening amount, and reduce the gap between the upper and lower walls of the door. It can be made small, and it can be completely closed with no gaps without cutting the butting ends of the doors into a sloping state. Furthermore, each door can be easily formed with a single rail, and it can be easily installed. , it is also possible to provide it at low cost.

The present invention is a further improvement of the above-mentioned door device, in which two engaging pieces are provided protruding from one side of the door in the front and back direction near both the running bodies of the left and right doors, and In the straight section of the door rail near the entrances of both the left and right evacuation sections, two guide pieces are protruded on one side in the front-rear direction of the door to engage and guide the above-mentioned engagement piece in a manner that allows the engaging piece to be engaged and disengaged in the width direction of the door. At the same time, the engaging pieces and the guide pieces are arranged so that when the door is opened and closed, the traveling body is guided along the straight line and is located near the entrances of the left and right evacuation sections. are arranged in such a position that they are engaged with each other so as to prevent the door from moving in the front-rear direction, and by this, when both the left and right doors are opened and closed,

In addition, in the illustrated example, both doors 1 and 2 are pulled out forward, rotated and tilted, and then opened by running sideways, but reversibly, both doors 1 and 2 are moved inward. In any case where the door is opened by moving in the lateral direction after being pushed in and rotated, the above-mentioned engaging pieces 13 to 16 and guide pieces 17, 1
8 are provided in the same positional relationship as described above.

In the above configuration, the door opening/closing operation is
This will be explained based on FIG. 3, FIG. 4, and FIG.

The left and right doors 1 and 2 are as shown in Figure 1.
The door is closed with the inner end portions 1a and 2a abutting each other, and this closed state is achieved by a stopper (not shown) provided at the end of the rail or by abutting against the ends of the left and right inclined portions 12b and 12b. As a result, both doors 1 and 2 are connected in a plane, and in this state, the traveling bodies 8 and 1
0 naturally engages with each inclined portion 12b, 12b of the door rails 12, 12, while the running bodies 9, 11 at the inner end of the door engage with the evacuation portions 12c, 12c.
The doors 1 and 2 are engaged with the opening edge 3d of the door mounting frame 3 with almost no gap, closing the opening 3a.

Further, in the closed door state, each of the engaging pieces 13 to 16 is in a position separated from the straight part 12a as shown in the figure,
It is located far away from both guide pieces 17 and 18.

To open the door 1 on the left side in the figure from the above-mentioned closed state, first grasp the handle 19 provided at the inner end 1a of the door 1 and pull it forward. Since a forward force is applied to the door 1, the door 1 rotates counterclockwise using the running body 8 at the outer end as a fulcrum, and as a result, the running body 9 escapes forward from the evacuation part 12c. The door 1 engages with the straight portion 12a, and the door 1 has an inner end portion 1a.
The sides move forward and become oblique as shown in Figure 3.

Next, when the door 1 is moved to the right as indicated by the arrow a in the drawing, each of the traveling bodies 8 to 11 is guided by both door rails 12 and 12 and moves to the right.

At this time, the traveling body 9 is on the straight parts 12a, 12a of both door rails 12, 12, but the other traveling body 8 is engaged with the inclined part 12b, so it initially stutters in an oblique state, and then on the left and right sides. As the door 1 moves in the direction, the door 1 rotates clockwise around the running body 9 as a fulcrum, and when the running body 8 reaches the straight part 12a, the door 1
It becomes parallel to the opening edge 3d of the door mounting frame 3, and thereafter moves in a straight line in a sideways state to the door opening stop position,
The other door 2 is opened in a heavily loaded state on the outside.

At this time, the brackets 4 and 5 of both doors 1 and 2 come into contact with each other, resulting in an open door end.

While the door 1 is being opened in this way, the traveling bodies 8 and 9 pass through the entrances of the evacuation sections 12c and 12c, but when the traveling body 8 reaches the straight section 12a, the traveling bodies 8 and 9 are near the said traveling body 8. One of the provided engagement pieces 13 is engaged with one of the guide pieces 17 in the door front-rear direction as shown in FIG. 4, and at this time, the other engagement piece 14 is engaged with the other guide piece 18 in the door width direction. The traveling body 9 is also located in front of the evacuation section 12c in the door width direction.

Further, the engagement piece 13 allows the traveling body 8 to
The guide piece 17 is engaged with the guide piece 17 before reaching the entrance of the evacuation section 12c, and remains engaged until the traveling body 8 passes the entrance of the evacuation section 12c, and is then disengaged. It is prevented from entering the portion 12c.

When the door 1 is further moved from the position shown in FIG. 4 to the right direction indicated by the arrow a, one of the engagement pieces 13 and the guide piece 17 disengage, but before this engagement disengages, the other engagement piece 13 disengages. The engagement piece 14 engages with the guide piece 18, and this engagement is continued until the traveling body 9 passes the entrance of the evacuation section 12c, and after the traveling body 9 passes the entrance, the above-mentioned engagement is removed, the door is opened until the brackets 4 and 5 of both doors 1 and 2 abut, and then stops, reaching the opening end.

At this time, since the arm 6 is designed to enter under the bracket 5 provided on the other door 2, the amount by which the door 1 opens increases.

Further, when the door 1 is opened, the running body 11 provided on the arm 7 of the right door 2 is engaged with the evacuation part 12c, and the other running body 10 is also engaged with the inclined part 12b, so that the running body 11 is not in a straight line. Since the linear part 12a and the door 2 are held parallel to each other at a position inwardly away from the part 12a, the door 1 can be opened as described above without interfering with the opening of the door 1.

In addition, when closing the door 1, moving the door 1 to the left from the above-mentioned closed state causes the traveling bodies 8, 8,
9, 9 is the straight part 12 of both door rails 12, 12
a, 12a and moves to the left in parallel, and when one of the traveling bodies 8 reaches the inclined part 12b, the door 1 moves while rotating counterclockwise.
The running body 8 hits the stopper or the end of the inclined part 12b and comes to a closed end, but if it continues as it is,
Since the door 1 is in the inclined state shown in FIG. 3, when the door inner end 1a is pushed inward and the door 1 is rotated clockwise, the traveling body 9 at the entrance of the evacuation section 12c will be The door 1 is engaged with the evacuation part 12c, and the door 1 is closed as shown in FIG.
The door is closed with 2a butted against each other, and
The straight portions 12a of both door rails 12, 12 are prepared to allow the other door 2 to open.

Furthermore, while the door is being closed as described above, both the traveling bodies 8 and 9 pass through the entrances of the evacuation sections 12c and 12c, but when the door 1 is moved to the left by an appropriate distance, the arm first The traveling body 9 on the 6th side reaches the entrance of the evacuation section 12c, but at this time, when the traveling body 9 approaches the entrance, the engaging piece 14 engages with the guide piece 18, and the traveling body 9 reaches the entrance. After passing through
At the same time that the engagement between the engagement piece 14 and the guide piece 18 is released, the traveling body 8 on the bracket 4 side approaches the entrance of the other evacuation part 12c, and at this point the other engagement piece 13 engages with the guide piece 17. After the traveling body 8 passes through the entrance of the evacuation part 12c, the engagement is released,
Next, the traveling body 8 engages with the inclined portion 12b as described above, and the door is closed.

Therefore, even during the door closing operation, the traveling bodies 8 and 9 are prevented from entering the evacuation section 12c, so the door 1 is opened and closed along a predetermined movement trajectory.

Also, when opening and closing the other door 2, or in the case of the other embodiment shown in FIG. 5 and the planar closing sliding door device for the entrance shown in FIG. Since the operations are the same, their explanation will be omitted.

As explained above, according to the flat sliding sliding door device according to the present invention, the brackets 4 and 5 are provided at both the upper and lower ends of the left and right doors 1 and 2, at both the inner and outer ends in the door width direction. Both doors 1,
