2. Description of the Related Art Conventionally, for example, a three-door sliding door type cabinet as described in Japanese Patent No. 2748087,
JP-A-4-343988 and JP-A-8-1934
A five-door sliding door type cabinet as described in JP-A-68-68 is known.

[0003]

In these three-seat and five-seat sliding door cabinets, the opening size of the front opening can be widened, but the number of rails or the entire number of sliding doors is large, and the thickness is large. There was a problem that the depth dimension of the cabinet body was reduced.

[0004] In view of the above problems, an object of the present invention is to provide a cabinet door device in which the depth of a cabinet body can be increased in a three-sliding door.

[0005]

According to the present invention, the above-mentioned problem is solved as follows. (1) A cabinet door device in which a front opening of a cabinet is opened and closed by interlocking three sliding doors overlapping in a front-rear direction of a front sliding door, an intermediate sliding door, and a rear sliding door,
Two front and rear rails facing left and right are provided on the top plate and the bottom plate of the cabinet body so as to face up and down, and a door wheel provided above and below the front sliding door is moved along the front rail of the rails. The sliding door provided above and below the intermediate sliding door is movable along a rear rail of the rail, and is moved along the front rail above and below a free edge of the rear sliding door. A possible door roller is provided, and a guide door roller is provided above and below a portion where the rear sliding door overlaps with the intermediate sliding door, and is movable along a guide rail fixed vertically on the back side of the intermediate sliding door.

(2) In the above item (1), the front and rear two rails are convex rails, and the rear side of the rear rail has a bottom surface higher than the lower surface of the top plate on the top plate side. Then, a recessed step portion whose bottom surface is lower than the upper surface of the bottom plate is formed on each of the upper and lower sides, and the upper and lower surfaces of the surface plate of the rear sliding door are bent rearward, and the bent portion is fitted into the recessed step portion.

Is provided.

The front edges of the top plate and the bottom plate (6) in the cabinet body (1) project forward from the front edges of the left and right side plates (1a) to form a projection, and the front sliding door (2) And the front surface of the sliding door (4) on the free edge (right edge) side thereof are disposed on the same plane between the top plate and the protruding portion of the bottom plate (6) so as to be able to freely contact and separate.

FIGS. 4 and 5 are front and plan views, respectively, of the front sliding door (2). As can be seen from these figures and FIG. A door wheel (9) which is formed by bending both side edges of one surface plate inward, and which is mounted on the front rail (7) above and below the both ends.
Is attached. Inside the left end is the cabinet body
A door stop (10) to the side of (1) is attached.

FIGS. 6 and 7 are front and plan views, respectively, of the intermediate sliding door (3). As can be seen from these figures and FIG. 2, the intermediate sliding door (3) also has one surface plate. Are formed by bending both side edges inwardly, and a door wheel (9) is attached inwardly and vertically on both ends.

The left end of the intermediate sliding door (3), that is, the front sliding door (2).
On the side, a plurality of (three in the illustrated example) stopper claws (11) projecting forward and folded inward are formed. These stopper claws (11) are, as shown in FIG.
To stop or interlock the movement of the intermediate sliding door (3). Also the upper door wheel
(9) On the lower and lower door rollers (9), guide rails (12) extending in the horizontal direction and having an L-shaped cross section are provided on the back surface of the front plate so as to face up and down (inside up and down). (Can) be fixed.

FIGS. 8 and 9 are front and plan views, respectively, of the rear sliding door (4). As can be seen from these figures and FIG. 2, the rear sliding door (4) also has one surface plate. Is formed by bending both side edges inward, and the right end side, that is, the free end side, is bent forward, and is again bent to the side at a position flush with the surface of the front sliding door (2) described above. Stepped (1
A door wheel (9) mounted on a front rail (7) is attached above and below the step (13).

The left end of the rear sliding door (4), that is, the intermediate sliding door (3).
On the upper and lower sides of the front side, guide door rollers (14) are fixed at positions matching the guide rails (12) of the above-mentioned intermediate sliding door (3).

On the left end of the rear sliding door (4), that is, on the side of the intermediate sliding door (3), a plurality (three in the illustrated example) of stopper claws (15) projecting forward and folded inward are formed. ing. As shown in FIG. 2, these stopper claws (15) are fitted to the folded portion on the right side of the intermediate sliding door (3) to stop or interlock the movement of the rear sliding door (4).

The upper and lower ends of the rear sliding door (4) are bent twice rearward, that is, inward, to form a flange (16). The front end of the flange (16) is provided at the front end of the bottom plate (6) of the cabinet body (1) and the front end of the top plate (20) to be described later. It has a length that does not protrude more than (FIGS. 13 and 14).

The puller (5) provided on the right end of the rear sliding door (4), that is, the step (13) is provided with a latch device (the puller (5) of the front sliding door (2) is also used). The details are shown in FIG.
Is shown in cross section. As you can see in this figure, the puller
The latch claw (17) built in (5) is the vertical axis of the puller (5).
(18)
It can be engaged with the latch hole (19) formed in the side plate (1a) of (1).

FIG. 11 is a plan view of only the sliding doors showing the overlapping state of the three sliding doors (2), (3) and (4) when the front opening is fully opened. FIG. FIG. 4 is a plan view showing the state of three sliding doors (2), (3), and (4) when the door is closed.

As shown in FIGS. 13 and 14, a recessed step (21) is formed at the front end of the cabinet body (1) on the side of the top plate (20) and on the side of the bottom plate (6). The molding member (22) having the convex front rail (7) and the rear rail (8) here is higher on the top plate side than the lower surface of the top plate (20), and on the bottom plate side It is fitted so that it is lower than the upper surface of the bottom plate (6).

When installing the sliding door, first, the rear sliding door
(4) is mounted on the cabinet body (1) such that the upper and lower door rollers (9) at the free ends are fitted to the front rail (7). At this time, as described above, the tip of the flange (16)
In this state, the folded length is such that it does not protrude from the recessed step (21). Next, the intermediate sliding door (3) is arranged such that the upper and lower door rollers (9) are fitted to the rear rail (8),
In this state, the guide door (4) of the rear sliding door (4) is fitted to the upper and lower guide rails (12) by moving to the rear sliding door (4) side. Finally, the front sliding door (2) is arranged such that the upper and lower door rollers (9) are fitted to the front rail (7).

As shown in FIGS. 3 and 11, when the rear sliding door (4) is pulled out from the state in which the sliding doors are overlapped (open state), the end of the rear sliding door (4) becomes the next intermediate sliding door (3). 1 and is pulled out, and is fully closed as shown in FIGS. 1 and 12 in a state where the end of the intermediate sliding door (3) is engaged with the end of the front sliding door (2). In this state, the front sliding door (2) and the rear sliding door (4)
Covers the front ends of both side plates (1a), and latches (17).
Even when the sliding door is opened from the fully closed state, the sliding doors are successively opened in conjunction with each other to reach the state shown in FIG.

[0022]

According to the first aspect of the present invention, when the sliding door is opened, the size of the opening can be made large, and the number of rails may be two even though the sliding door is three. It can be larger than a single sliding door cabinet.

According to the second aspect of the present invention, the structural strength of the rear sliding door is increased by the flange, and the flange is housed in the recessed step portion.
This flange does not protrude from the bottom plate surface (or top plate surface), and the accommodation depth inside the cabinet can be increased.
