  As shown in FIG. 2, the tray 4 includes a container portion 10 including a front wall 10a, a rear wall 10b, a left wall 10c, a right wall 10d, and a bottom wall 10e. The left wall 10c and the right wall 10d have side surfaces 10f and 10g facing the horizontal panels 2c and 2d, respectively. The tray 4 also has a left protrusion 12 protruding leftward from the side surface 10f of the left wall 10c and a right protrusion 14 protruding rightward from the side surface 10g of the right wall 10d. As shown in FIG. 3, the outer dimension W1 from the left wall 10c to the right wall 10d is smaller than the inner dimension W2 between them so as to enter between the opposing horizontal panels 2c and 2d, and the left and right sides of the front wall 10a. The direction dimension W3 is larger than the inner dimension W2 between the opposing horizontal panels 2c and 2d. The left protrusion 12 and the right protrusion 14 are configured to be inserted into the groove rail 8 in the front-rear direction A3. Further, the outer dimension W4 from the left protruding portion 12 to the right protruding portion 14 is smaller from the front side toward the rear side. Since the left protrusion 12 and the right protrusion 14 are symmetrically configured, only the right protrusion 14 will be described below.

  As shown in FIGS. 3 and 4, the right protrusion 14 has locking portions 16 a and 16 b that can be locked to the upper surface 8 b and the lower surface 8 c of the groove rail 8 by protruding in the vertical direction A 1. Has a place. Specifically, the right protrusion 14 includes a rear fixed portion 18a connected to the rear portion of the right wall 10d, and extends obliquely upward and forward from the rear fixed portion 18a with a distance from the right wall 10d. The rear side bending portion 20a that can be bent in the vertical direction A1 with respect to 18a, the front side fixing portion 18b connected to the right wall 10d in front of the rear side bending portion 20a, and the front side fixing portion spaced apart from the right wall 10d A front side bending portion 20b that extends obliquely upward from 18b and can be bent in the vertical direction with respect to the front side fixing portion 18b, and a front wall fixing portion 18c connected to the right wall and the front wall in front of the front side bending portion 20b. Have. The rear fixed portion 18a and the rear flexible portion 20a correspond to the rear locking portion 16a, and the front fixed portion 18b and the front flexible portion 20b correspond to the front locking portion 16b.

  As shown in FIG. 4, each of the rear fixed portion 18 a and the front fixed portion 18 b has a vertical dimension H 1 smaller than a vertical dimension H 2 of the concave portion 8 a of the groove rail 8, and the right protrusion 14 is formed on the groove rail 8. It has a lower surface 22 that is pressed against the lower surface 8c of the groove rail 8 when inserted. Each of the rear-side bent portion 20a and the front-side bent portion 20b has an upper surface 24 that is pressed against the upper surface 8b of the groove rail 8 when the right protrusion 14 is inserted into the groove rail 8. When the right protrusion 14 is not inserted into the groove rail 8, the vertical dimension H3 from the lower surface 22 of the rear fixed portion 18a and the front fixed portion 18b to the upper surface 24 of the rear bent portion 20a and the front bent portion 20b. Is larger than the vertical dimension H2 of the recess 8a of the groove rail 8. Thus, when the right protrusion 14 is inserted into the groove rail 8, the rear locking portion 16a and the front locking portion 16b can each be extended in the vertical direction A1 within the groove rail 8, and the tray 4 A locking force for locking the frame to the groove rail 8 is generated.

  Moreover, it is preferable that the front side bending part 20b can be bent in the left-right direction A2 with respect to the front side fixing part 18b, and when the right protruding part 14 is inserted into the groove rail 8, the concave part 8a of the groove rail 8 is formed.

Thus, the locking force due to the protrusion of the front locking portion 16b is larger than the locking force due to the protrusion of the rear locking portion 16a.

  Further, the front-rear direction distance L1 from the rear end 11b of the tray 4 to the rear locking portion 16a (the upper surface 24 of the rear bending portion 20a) is the front locking portion 16b (front bending portion) from the front end 11a of the tray 4. It is preferably longer than the distance L2 in the front-rear direction to the upper surface 24) of 20b.

  Next, the tray loading / unloading operation will be described.

  When inserting the tray 4, the rear fixed portion 18 a of the left protrusion 12 and the right protrusion 14 is inserted into the groove rail 8. Since the vertical dimension H1 of the rear fixed portion 18a is smaller than the vertical dimension H2 of the recess 8a of the groove rail 8, the tray moves smoothly.

  When the rear side bending portion 20a is pushed into the groove rail 8, the rear side bending portion 20a is bent downward with respect to the rear side fixing portion 18a, and the lower surface 22 of the rear side fixing portion 18a is pressed against the lower surface 8c of the groove rail 8. The upper surface 24 of the rear side bending portion 20a is pressed against the upper surface 8b of the groove rail 8, so that the locking force due to the protrusion of the rear side locking portion 16a acts on the tray 4. However, since the locking force due to the protrusion of the locking portion 16a on the rear side is relatively small, the tray 4 can be easily moved by pushing the tray 4.

  When the tray is further pushed in, the front bending portion 20b is bent downward with respect to the front fixing portion 18b, the lower surface 22 of the front fixing portion 18b is pressed against the lower surface 8c of the groove rail 8, and the upper surface 24 of the front bending portion 20b is a groove. It is pressed against the upper surface 8 b of the rail 8, whereby the locking force due to the protrusion of the front locking portion 16 b acts on the tray 4. Due to the protrusion of the rear locking portion 16a and the protrusion of the front locking portion 16b, the tray 4 is locked to the tray without rattling. Since the locking force due to the protrusion of the rear locking portion 16 a is relatively large, the tray 4 is firmly locked to the groove rail 8. By pushing the tray 4 slightly stronger, the tray 4 can be moved until the front wall 4a of the tray 4 comes into contact with the horizontal panels 4c and 4d.

  When the tray 4 is taken out, the pushing operation when inserting the tray 4 may be replaced with a pulling operation.

  In the storage cabinet 1 described above, since the rear locking portion 16a and the front locking portion 16b protrude from the groove rail 8 at two locations in the front-rear direction, the tray 4 is engaged with the groove rail 8 without rattling. Can be stopped. Thereby, the convex part 62 provided in the back panel 54 of the storage cabinet 50 of a prior art becomes unnecessary, and the surface 2h of the back panel 2g can be made flat. As a result, the storage space of the storage cabinet 1 can be increased, and an unnecessary line disappears from the appearance.

  Further, since the storage cabinet 1 described above has the two locking portions 16a and 16b, the total locking force of the conventional storage cabinet can be distributed to the locking portions 16a and 16b. . Therefore, it is possible to prevent the tray 4 from suddenly moving when the tray 4 is inserted or removed.

  Further, since the locking force of the rear locking portion 16a is made relatively weak and the locking force of the front locking portion 16b is made relatively strong, the operation of loading and unloading the tray 4 can be performed. It can be performed with a relatively weak stopping force. When the tray 4 is completely inserted, the tray 4 can be firmly locked to the groove rail 8 with the same locking force as that of the conventional storage cabinet. . Further, since the front-rear direction distance L1 from the rear end 11b of the tray 4 to the rear side locking portion 16a is longer than the front-rear direction distance L2 from the front end 11a of the tray 4 to the front side locking portion 16b, The rate at which the tray 4 is moved in a state where the locking force of the front locking portion 16b does not work is increased, so that the tray 4 can be inserted and removed more smoothly. Therefore, for example, when the tray 4 is removed, the tray 4 is not dropped excessively.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims. Needless to say, these are also included within the scope of the present invention.

  In the said embodiment, although the storage cabinet for vanity was demonstrated as an example of the storage unit of this invention, the storage unit of this invention is not limited to it. For example, the storage unit may be another storage box, a shelf, or the like, or a refrigerator that uses the tray described above.

  Although the two protrusions 16a and 16b are provided on the left protrusion 12 and the right protrusion 14, respectively, three or more engagement parts may be provided.

  Moreover, in the said embodiment, although the latching | locking part 16a, 16b was comprised as the fixed part 18a, 18b and the bending part 20a, 20b, if it can latch to the groove rail 8 so that the protrusion parts 12 and 14 may be stretched, other It may be a structure.
