  FIG. 10 is a cross-sectional view taken along line BB in FIG. As shown in FIGS. 9 and 10, the outer rail 320L is fixed to the inner surface of the left side plate 110L and is formed in a rectangular plate, and the right side direction (FIG. 10) from the upper edge of the mounting portion 321L. The upper piece 322L protruding in the Y direction), the lower piece 324L protruding rightward from the lower edge of the mounting portion 321L, and the outer side roller 325L provided at the front portion of the mounting portion 321L. .

  The inner rail 310L protrudes from the upper edge of the main body 311L to the left lateral direction (the −Y direction in FIG. 9) and functions as the left side plate of the drawer 200, and extends to the outer roller 325L described above. The protruding piece 312L is mounted on the rear upper part of the main body 311L, and the inner roller 315L is mounted on the lower piece 324L of the outer rail 320L.

  The left outer rail 320L and the inner rail 310L are formed substantially symmetrically with the right one. However, in the illustrated conventional example, the left outer rail 320L does not include a member corresponding to the roller drop-off preventing piece 323R of the right outer rail 320R as shown in FIG.

  With the protrusions 312L and 312R of the left and right inner rails 310L and 310R and the inner rollers 315L and 315R entering the inner regions S1 and S2 (see FIGS. 8 and 10) of the outer rails 320L and 320R, The side rollers 315L and 315R are placed on the lower pieces 324L and 324R of the outer rails 320L and 320R, and the projecting pieces 312L and 312R of the inner rails 310L and 310R are placed on the outer side rollers 325L and 325R, whereby the inner rails 310L and 310R are It is supported by 320R. When the drawer 200 is opened and closed, the inner rails 310L and 310R move in the front-rear direction with respect to the outer rails 320L and 320R. At this time, the outer side rollers 325L and 325R and the inner side rollers 315L and 315R rotate, so that the inner rails 310L and 310R move smoothly with respect to the outer rails 320L and 320R.

  In order to prevent the withdrawal of the drawer due to the opening operation of the drawer 200, stopper portions 350L and 350R are provided at positions near the inner side rollers 315L and 315R of the protruding pieces 312L and 312R of the inner rails 310L and 310R. The stopper portions 350L and 350R prevent the inner side rollers 315L and 315R at the rear of the inner rail from approaching the outer side rollers 325L and 325R by the opening operation of the drawer 200.

  The drawer 20 includes a bottom plate 21, a front plate 22, a back plate 23, left and right side plates 24 </ b> L and 24 </ b> R, a bar 25 that connects the front plate 22 and the back plate 23, and the front plate 22 and the bottom plate 21. And a metal fitting 26 to be connected. In FIG. 1, the right side plate 24R is not shown.

  In the drawer 20 according to the present embodiment, the left and right side plates 24L and 24R are constituted by inner rails 330L and 330R, respectively.

  As shown in FIG. 2, outer rails 320 </ b> L and 320 </ b> R that guide these inner rails 330 </ b> L and 330 </ b> R are attached to the inner surfaces of the left and right side plates 11 </ b> L and 11 </ b> R of the cabinet 10. In the drawing, the top plate, the right side plate 11R, and the right outer rail 320R attached to the inner surface thereof are not shown. 2 is a piping box that accommodates piping such as a water supply pipe, a hot water supply pipe, and a drain pipe. A hole through which the pipe is passed is formed on the upper surface of the piping box 15. It is connected to the faucet etc.

  3A and 3B are views showing the rail member according to the first embodiment of the present invention, in which FIG. 3A is a right outer rail 320R, FIG. 3B is a right inner rail 330R, and FIG. 3C is a left outer rail 320L. , (D) shows the left inner rail 330L.

  In the present embodiment, the left and right outer rails 320L and 320R are the same as those shown in FIGS. 7A and 9A, and thus detailed description thereof is omitted. Note that the left outer rail 320L does not include a member corresponding to the roller drop-off preventing piece 323R of the right outer rail 320R, as in the prior art outer rail shown in FIG.

  On the other hand, the left and right inner rails 330L and 330R are different in configuration from the conventional inner rails 310L and 310R shown in FIGS. 7B and 9B as follows.

  Specifically, the right inner rail 330R shown in FIG. 3B includes a plate-like main body portion 311R that functions as a side plate of the drawer 20, and a right lateral direction from the upper edge of the main body portion 311R (FIG. 3B). Projecting piece 312R that projects in the outer roller 325R (see FIG. 3A) and a rear upper part 324R of the outer rail 320R (see FIG. 3A). 7), the inner side roller 310R has the same configuration as that of the conventional inner rail 310R shown in FIG. 7B, but the conventional inner rail 310R includes one stopper portion 350R. On the other hand, the inner rail 330R of this embodiment includes two stopper portions.

  The inner rail 330R on the right side shown in FIG. 3B is in contact with the outer roller 325R (see FIG. 3A) and the first stopper portion 410 and the second stopper that regulate the relative movement between the inner rail 330R and the outer rail 320R. The stopper part 420 is provided. As shown in FIG. 3B, the first stopper portion 410 is composed of one convex portion 411, and the second stopper portion 420 is composed of two convex portions 421 and 422.

  FIG. 4 is an enlarged schematic view of the periphery of the first stopper portion 410 and the second stopper portion 420. The convex portions 411, 421, and 422 partially protrude downward from the protruding piece 312R of the inner rail 330R, for example, downward It is formed to protrude from the mold. The interval W1 between the convex portion 411 of the first stopper portion 410 and the convex portion 421 on the front side of the second stopper portion 420 is set wider than the interval W2 between the two convex portions 421 and 422 of the second stopper portion 420. .

  As shown in FIG. 3B, the first stopper portion 410 according to the present embodiment is provided between an intermediate portion and a rear portion in the front-rear direction of the inner rail 330 </ b> R, and the second stopper portion 420 is more than the first stopper portion 410. Is also provided near the inner roller 315R. The second stopper portion 420 according to the present embodiment corresponds to a conventional stopper portion in that it is provided closer to the inner side roller 315R, but at the front side of the second stopper portion 420 on the rail rear end side. The configuration is different from the conventional inner rail 310R in that it includes a first stopper portion 410 that restricts relative movement between the inner rail 330R and the outer rail 320R.

  The left inner rail 330L is formed in a substantially symmetrical shape with the right one and includes two stopper portions 410 and 420 as in the right side.

  FIG. 5A is a cross-sectional view of the cabinet 10 with the drawer 20 according to the present embodiment closed. In this state, as shown in FIG. 5B, the outer side rollers 315L, 315R and the first stopper portion 410 are separated from each other.

When the drawer 20 is opened by performing the drawer operation from the closed state of FIG. 5A, the first stopper portion 410 is also moved by the movement of the drawer 20. When the opening operation is continued, the convex portion 411 of the first stopper portion 410 comes into contact with the outer side rollers 315L and 315R. Thereby, the movement of the inner rails 330L and 330R with respect to the outer rails 320L and 320R, that is, the opening operation of the drawer 20 is restricted. Hereinafter, this state in which the opening operation is restricted is referred to as a “first restriction state”. At this time, the drawer 20 is pulled out in a state in which the back part of the drawer is left in the cabinet 10 with a length R1.
This embodiment is characterized in that this amount R1 is set as follows.

  The withdrawal amount R1 is set so that the drawer 20 does not rotate even if one of the left and right ends of the front plate 22 of the drawer 20 is pressed in the first restricted state. For example, the interval between the inner roller and the outer roller is wide so that the drawer does not rotate when the drawer in the first restricted state is pushed to close the drawer, for example, 50 mm to 100 mm wider than the conventional gap. A leftover amount R1 is set. Here, when the amount of residual is increased, the distance between the inner roller and the outer roller is increased. In other words, as a method of widening the distance between the inner side roller and the outer side roller, there is a method of increasing the remaining amount. Thus, in the present embodiment, the position of the first stopper portion 410 is selected.

  When a force is further applied to pull out the drawer 20 from the first restricted state of FIGS. 5C and 5D, the outer side rollers 315L and 315R get over the convex portion 411 of the first stopper portion 410. When the drawer 20 is further pulled out, the convex portion 421 on the front side of the second stopper portion 420 comes into contact with the outer side rollers 315L and 315R. Thereby, the movement of the inner rails 330L and 330R with respect to the outer rails 320L and 320R, that is, the opening operation of the drawer 20 is restricted. Hereinafter, the state that restricts the opening operation is referred to as a “second restriction state”. At this time, the drawer 20 is pulled out in a state where the back part of the drawer is left in the cabinet 10 with a length R2.

  This remaining amount R2 is set to a dimension that prevents the drawer 20 from rotating when the end portion of the front plate 22 on the side where the roller drop-off preventing piece is not provided is pressed in the second restricted state. .

  If the opening operation of the drawer is further continued in the second restricted state, the outer side rollers 325L and 325R get over the front convex portion 421 of the second stopper portion 420, but the opening operation is again performed by the rear convex portion 422. Is regulated. As described above, the main function of the second stopper portion 420 on the rear side is to make it difficult for the drawer 20 to be detached from the cabinet 10.

  According to the cabinet 10 according to the present embodiment configured as described above, when the drawer 20 is closed from the first restricted state shown in FIGS. 5C and 5D, the roller drop-off preventing piece is attached to the outer rail. Of the outer side rollers 325L and 325R and the inner side rollers 315L and 315R on each side in the state where the drawer 20 is opened (first restricted state) even if the left end of the front plate 22 is pushed. The distance between the front outer rollers 325L and 325R and the rear inner rollers 315L and 315R is, for example, about 50 mm to 100 mm wider than that of the conventional structure. It can be closed as it is without rotating. This is because even if the left end portion of the front plate 22 of the drawer 20 is pushed, the force does not act as a force for rotating the drawer 20, but acts as a force for moving the inner rails 330L and 330R on the left and right sides. Conceivable.

  By providing the first stopper portion 410, a wide space between the outer side rollers 325L and 325R and the inner side rollers 315L and 315R can be reliably ensured. As a result, the distance between the rollers by the second stopper portion 420 can be made wider, so that even if the drawer 20 is opened with a heavy article in the drawer, the drawer 20 can be pulled out in a stable state without tilting forward. Can be opened.

[Second Embodiment]
Unlike the first embodiment, the cabinet according to the second embodiment of the present invention includes the first stopper portion 410 only on one of the left and right inner rails. That is, one inner rail includes both the first stopper portion 410 and the second stopper portion 420, while the other inner rail includes only the second stopper portion 420.
Also in the second embodiment, the drawer 20 can be smoothly closed as in the first embodiment.

[Third Embodiment]
Whereas the first embodiment and the second embodiment are provided with two convex portions 421 and 422 as the second stopper portion 420, the cabinet according to the third embodiment of the present invention is provided with the second stopper portion 420. One of the two convex portions 421 and 422 is omitted from the configuration.
Also in the third embodiment, the drawer 20 can be smoothly closed as in the first embodiment and the second embodiment.

〔Example〕
When the total length of the inner rail 330R is about 450 mm, the convex portion 411 of the first stopper portion 410 is provided at a position of about 110 mm from the rail rear end, and the rear convex portion 422 of the second stopper portion 420 is provided from the rail rear end. It was provided at a position of about 57 mm. And the space | interval W2 of the two convex parts 421 and 422 of the 2nd stopper part 420 was set to about 17 mm. In this configuration, when the drawer 20 is closed from the first restricted state shown in FIGS. 5C and 5D, the outer rail is provided with no roller drop-off preventing piece, that is, the left end of the front plate 22. Even if the part was pushed, the drawer 20 could be closed without rotating.

  As described above, the present invention can be implemented in various forms without departing from the spirit of the invention.

The present invention can be applied to a cabinet constituting a system kitchen or a vanity.
The shape of the convex portion of the first stopper portion 410 and the two convex portions of the second stopper portion 420 is not limited to the illustrated example, and various shapes such as a triangular shape, a square shape, and a piece shape may be used. . Moreover, the convex part of the 1st stopper part 410 and the two convex parts of the 2nd stopper part 420 are good also as a structure which attaches another members, such as a cylindrical pin, to the protrusion piece of an inner rail.
