  FIG. 9 is a cross-sectional view taken along the line BB in FIG. As shown in FIGS. 8 and 9, the outer rail 320L includes a mounting portion 321L formed on a rectangular plate fixed to the inner surface of the left side plate 110L, and a right lateral direction (see FIG. 9) from the upper edge of the mounting portion 321L. The upper piece 322L protrudes in the Y direction), the lower piece 324L protrudes rightward from the lower edge of the attachment portion 321L, and the outer side roller 325L provided at the front portion of the attachment portion 321L.

  The inner rail 310L projects from the upper edge of the main body 311L to the left lateral direction (the −Y direction in FIG. 8) and functions as a 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 prevention 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. 7 and 9) 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, the first restriction portions 330L and 330R 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 first restricting portions 330L and 330R 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.

  As shown in FIGS. 6B and 8B, the first restricting portions 330L and 330R are two convex portions protruding downward from the rear regions of the projecting pieces 312L and 312R of the inner rails 310L and 310R. It is configured. If the outer side rollers 325L and 325R come into contact with the convex portion during the opening operation of the drawer 200, the opening operation of the drawer 200 is restricted. If the opening operation of the drawer is further continued in this state, the outer side rollers 325L and 325R get over the first convex portion, but the opening operation is again restricted by the second convex portion.

  In the cabinet 100 having such a rail member 300, when the left end of the front plate 210 is pushed when the drawer 200 is closed from the state where the drawer 200 is most opened, the drawer 200 is moved with respect to the cabinet 100 as shown in FIG. Rotate. At this time, if the left inner roller 315L falls off the outer rail 320L, the drawer 200 cannot be moved. When the rotation of the drawer 200 is observed, when the left end portion of the front plate 210 of the drawer 200 is pushed, the distance between the right outer roller 325R and the inner roller 315R is almost the same, but the left outer roller 325R is the same as the left outer roller 325R. The interval with the inner roller 315R is widened. That is, it can be said that the drawer rotates around the right inner roller. This rotation of the drawer occurs when the left end of the drawer front plate is pushed, that is, when a force is applied from the side where the roller fall-off prevention piece is not provided on the outer rail, and the right outer side roller and the inner side roller It is more likely to occur as the interval is narrower.

  There is Patent Document 1 that takes into account the problem that the drawer cannot be moved due to the rotation of the drawer.

  Patent Document 1 discloses a drawer for a storage cabinet. A roller drop-off preventing piece is provided on one side of the left and right cabinet-side rails on the front and rear sides, and a rail side without a roller drop-off preventing piece is provided. The cabinet and the drawer are provided with guide means for guiding the drawer side rail toward the cabinet side rail at the position where the drawer is opened.

Is selected. The reason for adjusting the length in this way is that if the inner rail 310R extends to the upper region of the piping box 15, for example, there is a risk of hitting the piping (not shown) extending upward from the piping box 15. is there.

  Further, in the cabinet 10 according to the present embodiment, the inner side rollers 315L and 315R and the outer side rollers 325L and 325R that are restricted by the first restriction portions 330L and 330R (see FIGS. 6B and 8B), The inner side rollers 315L and 315R have a second restricting portion 30 that prevents the inner side rollers 315L and 315R from approaching the outer side rollers 325L and 325R at a position wider than the distance between them.

  The 2nd control part 30 is comprised from the rotation piece 31 provided in the drawer 20, and the stopper pin 32 provided in the cabinet.

  As shown in FIG. 1, the rotating piece 31 has a base member attached to the left and right ends of the back plate 23 of the drawer 20 with a shaft member 41. The back plate 23 to which the rotating piece 31 is attached is selected to have a size higher than that of the inner rails 310L and 310R. The rotating piece 31 is not covered with the inner rails 310L and 310R and is exposed at the end of the back plate 23 exposed. It is attached. The tip of the rotating piece 31 is in contact with the protruding pieces 312L and 312R of the inner rails 310L and 310R at a position closer to the front plate 22 than the position of the shaft member 41. With such a configuration, the rotating piece 31 cannot be rotated by pushing the tip part further downward.

  As shown in FIG. 2, the stopper pin 32 is provided on the inner surface of the side plate 11 </ b> R of the cabinet 10. The stopper pin 32 is provided on a locus along which the rotating piece 31 moves when the drawer 20 is opened. When the drawer 20 is pulled out by a certain amount, the stopper pin 32 comes into contact with the rotating piece 31 and restricts the opening operation of the drawer 20. To do. Thereby, the inner side rollers 315L and 315R are prevented from approaching the outer side rollers 325L and 325R. The stopper pin 32 is disposed at a position wider than the distance between the inner side rollers 315L, 315R and the outer side rollers 325L, 325R regulated by the first regulating portions 330L, 330R, for example, at a position wider by about 50 mm to 100 mm. The attachment positions are selected so as to prevent 315L and 315R from approaching the outer side rollers 325L and 325R.

  According to the cabinet 10 according to the present embodiment configured as described above, when the drawer 20 is closed, even if the side where the roller drop-off preventing piece is not provided on the outer rail, that is, the left end of the front plate 22 is pressed, Since the distance between the outer roller 325R and the inner roller 315R opposite to the side to which the force is applied with the drawer 20 opened is wide, that is, the front outer roller 325R and the rear inner side. Since the distance from the roller 315R is, for example, about 50 mm to 100 mm wider than the conventional structure, the drawer 20 can be closed as it is without being rotated. 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 310L and 310R on the left and right sides. Conceivable.

  By providing the second restricting portion 30, it is possible to reliably ensure a wide interval between the outer side rollers 325L and 325R and the inner side rollers 315L and 315R. As a result, the distance between the rollers by the first restricting portion can be made wider, so 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.
