According to the prior art, since the sliding door is guided by the sill and the kamoi and only moves linearly in the left-right direction, the front surface is completely flat when closed. There was a problem that it could not be displayed and it did not look good. For example, when one sliding door is used, a step is formed between the surface of the sliding door and the surface of the door pocket, and when a sliding door is used, it is inevitable that a step is formed on the surfaces of the two sliding doors.

Therefore, in view of the problems of the prior art, an object of the present invention is to provide a guide member by combining a fixed member having a curved guide groove and a sliding member that moves obliquely with respect to the guide groove. The object of the present invention is to provide a sliding door device capable of closing the sliding door so that the front surface becomes flat and realizing a good appearance by configuring.

[0006]

The structure of the present invention for achieving the above object is a sliding door having a pair of front and rear guides and rollers at the upper and lower portions, and a pair of upper and lower guides for guiding the guides and the rollers. And a guide member, each of which has a curved guide groove for moving a front portion of the sliding door (a front portion in a traveling direction when the sliding door is moved in a closing direction, the same applies hereinafter) back and forth. A fixing member,
A sliding member that is slidably attached to the fixed member and that moves the rear portion of the sliding door (the rear portion in the traveling direction when moving the sliding door in the closing direction; the same applies below) back and forth. The summary will be given.

The sliding door may be a sliding door, and the sliding member may be provided corresponding to the sliding door.

Further, the fixing member may be formed by being divided into a basic portion for mounting the sliding member, an intermediate portion corresponding to the linear portion of the guide groove, and a tip portion corresponding to the tip portion of the guide groove. Good.

[0009]

According to the structure of the present invention, the upper and lower guide members each include a fixed member and a sliding member, and the fixed member has a curved guide groove, and when the sliding door is closed,
The front part of the sliding door can be moved to the front side, and the sliding member can move the rear part of the sliding door to the front side, so that when the closing is completed, the entire sliding door moves to the front side. It is possible to form a flat plane with respect to the surface of the door pocket or the surface of another sliding door.

When the sliding door is opened, the sliding door is guided by the guide groove and the sliding member and moves in the opening direction while retreating, and finally it is stored in the door pocket or behind another sliding door. can do.

When the sliding door is a sliding door, a sliding member is provided for each sliding door so that the sliding doors move to the front side when closed and to the rear side when opened. Therefore, one sliding door can be closed so as to be flat with the other sliding door, and can be opened so as to be housed behind the other sliding door.

The sliding doors 10 are movably attached to the fixing member 21.
And sliding members 22 and 22 corresponding to (FIGS. 1 and 4).

The fixing member 21 includes a guide groove 21a and slanted dovetail grooves 21b, 2 for mounting the sliding members 22, 22.
It is a plate material having 1b. The guide groove 21a is formed over substantially the entire length of the fixing member 21, and is smoothly curved at both ends toward the front surface of the sliding doors 10, 10. The guide groove 21a is formed by the guides 12, 12,
Corresponding to the rollers 13 and 13, in the straight part,
The sliding door 10 can be linearly guided to the left and right, and
At the curved portion, the front portion of the sliding door 10 can be moved back and forth. In addition, the dovetail grooves 21b and 21b obliquely intersect with the guide groove 21a in a central portion of the fixing member 21, and further, open toward the rear side of the sliding doors 10 and 10 and close toward the front side. It is formed in the open state.

Each sliding member 22 is a plate piece having a hat-shaped cross section which can be slidably inserted into the dovetail groove 21b (FIGS. 4 and 5). The sliding member 22 is formed with a guide groove 22a that obliquely crosses the surface thereof and a recess 22b that opens only on one side. Therefore, when the sliding member 22 is inserted to the frontmost part of the dovetail groove 21b, the guide groove 22
a corresponds to the position of the guide groove 21a, and the recess 22b is
It corresponds to the positions of the tips of the guide grooves 21a at both ends of the fixing member 21. The guide groove 22a and the recess 22b are formed with a very small taper so as to be somewhat wider toward the side where the recess 22b is opened. Further, the opening direction of the recess 22b is made to coincide with the opening direction of the corresponding sliding door 10. That is, the sliding members 22 and 22 are formed to be opposite to each other so as to correspond to the sliding doors 10 and 10.
The openings 2b are open in directions opposite to each other.

The guide members 20, 20 are fixed members 2
1, 21 guide grooves 21a, 21a, sliding members 22, 2
The two guide grooves 22a, 22a and the concave portions 22b, 22b are
Suitable mounting members 2 so that they face each other vertically.
The sliding doors 10 and 10 are mounted between the guide members 20 and 20 after being attached to the frame F of the cabinet via 0a and 20b (FIG. 2). The lower mounting member 20b integrally forms an appropriate frame portion 20b1 on the front surface side of the sliding door 10, while the cover member 20c is detachably attached to the upper surface of the upper fixing member 21 via a hook 20c1. Is attached to. Further, frame members F1 and F1 are attached to the frame F on both the left and right sides of the sliding doors 10 and 10 (FIGS. 6 and 7), and the frame portion 20b1 of the attachment member 20b, the cover member 20c, the frame members F1 and F1 are Also, it is assumed to be formed at the same height as the surfaces of the sliding doors 10 and 10 in the closed state.

Now, when the sliding door 10 is closed,
The guides 12, 12 of the sliding door 10 are engaged with the tip end portion of the guide groove 21a of the upper guide member 20 and the concave portion 22b of the sliding member 22 corresponding to the sliding door 10 (FIG. 1), and Similarly, the rollers 13 and 13 also have a lower guide member 20.
Of the guide groove 21a and the recess 22 of the sliding member 22
It is engaged with b (solid line in FIGS. 1 and 6). At this time, the upper and lower sliding members 22, 22 corresponding to the sliding door 10
Are dovetail grooves 21b and 21 of the fixing members 21 and 21, respectively.
With respect to b, it has moved to the foremost part, and therefore the sliding door 10 is parallel to the frame F and has moved to the front side to the maximum.

The limit of movement of the sliding door 10 in the closing direction is regulated by the rear guide 12 and the roller 13 engaging with the recesses 22b and 22b of the upper and lower sliding members 22 and 22, respectively. The limit of movement to the side is the dovetail 21
It is regulated by the movement limit of the sliding members 22 and 22 by b and 21b and the positions of the tips of the guide grooves 21a and 21a.

On the other hand, the open sliding door 10 is stored behind the closed sliding door (two-dot chain line in FIG. 6).
The rollers 13 of the sliding door 10 in the open state are both
It is in the straight part of the lower guide groove 21a, and at this time, the guides 12, 12 are in the straight part of the upper guide groove 21a (not shown). In addition, the movement limit of the sliding door 10 in the opening direction is regulated by blocking the guide grooves 21a, 21a by the corresponding upper and lower sliding members 22, 22 and blocking the advance of the front roller 13 and the guide 12. Has been done.

Now, consider the case where the open sliding door 10 is closed. However, at this time, the guides 12, 12
Guided by the upper guide member 20, the rollers 13, 13 are
The rollers are guided by the lower guide member 20, and both have the same mutual relationship with the corresponding guide member 20, so that only the rollers 13, 13 will be described below.

In FIG. 6, when a force is applied to the sliding door 10 in the open state in the direction of arrow K1 in the drawing, the sliding door 10
Can start linear movement in the closing direction, at which time the rollers 13, 13 advance along the linear portion of the guide groove 21a.

When the front roller 13 reaches the curved portion of the guide groove 21a, the guide direction of the roller 13 is changed by the guide groove 21a. Accordingly, the front portion of the sliding door 10 is moved to the front side. (Fig. 7). Therefore, when the front roller 13 passes through the curved portion of the guide groove 21a and enters the tip of the guide groove 21a, the rear roller 1
3 enters the recess 22b of the sliding member 22 corresponding to this sliding door 10 via the guide groove 22a of the sliding member 22 corresponding to the other sliding door 10, and thereafter, the sliding door 10 7 is moved in the direction of arrow K1 in FIG. 7, the sliding member 22 corresponding to the sliding door 10 can be advanced in the direction of arrow K2 in FIG. Sliding member 22
The reason is that the rear roller 13 can be driven in the direction of arrow K2 via the roller 13 by entering the closed recess 22b.

Therefore, if the sliding door 10 is further moved in the closing direction, the rear portion of the sliding door 10 moves to the front side due to the forward movement of the sliding member 22, and the sliding member 22 moves forward to the movement limit. Thus, the sliding door 10 can be closed so as to be flat with the other sliding doors 10 (FIG. 1). Even if the rear part of the sliding door 10 moves to the front side in this way, the rear part of the other sliding door 10 has the slope 11b, so that the sliding doors 10 and 10 do not interfere with each other.

The sliding door 10 thus closed can be opened smoothly by applying a force in the opening direction (the direction opposite to the arrow K1 direction in FIG. 7). However, at this time, first, since the rear roller 13 is constrained in the concave portion 22b of the sliding member 22, the sliding member 22 is driven to the rear side (the direction opposite to the arrow K2 direction in the figure). As the sliding member 22 retracts, the rear part of the sliding door 10 retracts. At the time when the sliding member 22 retracts until the recess 22b is aligned with the guide groove 21a, the rear roller 13 can slip out of the recess 22b to the guide groove 21a side.
At that time, since the front roller 13 advances along the curved portion of the guide groove 21a, the front part of the sliding door 10 retreats, so that the sliding door 10 subsequently advances along the linear portion of the guide groove 21a. , Can be moved to the open state by storing it behind the other sliding door 10 (Fig. 6).
The two-dot chain line).

The opening / closing operation described above can be freely performed on the other sliding door 10 as long as one of the sliding doors 10 is completely closed.

In the above description, the upper and lower guide members 2
The fixing members 21 and 21 of 0 and 20 respectively include a basic portion A1 on which the sliding members 22 and 22 are mounted, intermediate portions A2 and A2 corresponding to the straight portions of the guide groove 21a, and the guide groove 21.
It can be divided into tip portions A3, A3 corresponding to the tip portion of a (FIG. 1). Basic part A1, tip part A3, A3
By providing a plurality of types of intermediate portions A2 and A2 having different lengths, it is possible to easily deal with various overall widths of the sliding doors 10 and 10.

Further, the sliding member 2 with respect to the guide groove 21a
The oblique angle θ of 2 and 22 is generally set to θ = 45 (degrees). However, the crossing angle θ is the sliding doors 10, 10
As long as the smoothness of the operation of is not disturbed, θ> 45 (degrees),
It is also possible to set θ <45 (degrees). Also, the sliding door 10,
The slope angles of the slopes 11b and 11b of the sliding door 10 are
0 crossing angle θ, sliding door 1
It suffices to set it appropriately according to the thickness of 0 or 10.

Further, a key 3 is provided at the rear of one of the sliding doors 10.
0 can be attached (Fig. 8). By inserting a key (not shown) into the keyhole 31 and rotating the key 30,
The hook 32 can be rotated in the direction of arrow K3 in FIG.
It is possible to engage with the long hole 11b1 provided on the slope 11b (two-dot chain line in the figure). It should be noted that the slope 11b of the sliding door 10 on the side where the key 30 is attached is provided with an appropriate notch in accordance with the rotation trajectory of the hook 32 to avoid the hook 32 from interfering with the slope 11b.

It should be noted that such a sliding door device has one sliding door 10
By providing a door pocket instead of 1
It can be a single door. However, at this time, even if only one of the sliding members 22 and 22 is mounted, or even if a pair is mounted, the side not corresponding to the sliding door may be fixed by advancing to the movement limit. ..
