(Function and effect)
Next, in the disassembled state of the storage box 10, the operation and effect of the present embodiment will be described while explaining the procedure for nesting the box body 20 and the procedure for assembling the door 40 to the upper cover 50.

  In the storage box 10 configured as described above, the door 40 is rotatably provided at the front end of the storage box 10. For this reason, when storing contents such as shoes in the storage box 10, the user grasps the handle 44 of the door 40 and engages the door hook 46 of the door 40 with the surrounding wall 54 of the upper cover 50. By releasing, the opening part of the front-end part of the storage box 10 is opened. Thereby, contents such as shoes are stored in the storage box 10 from the opening.

(About box nesting)
As shown in FIG. 1A, when nesting a plurality of box bodies 20 in a state in which the storage box 10 is disassembled, the other box body 20 is disposed on the upper side of the one box body 20. 10A, the lower end portion of the other box body 20 is inserted into the upper end portion of the one box body 20 from the upper side. At this time, the other box body 20 is inserted into the one box body 20 so that the fitting rib 22 of the one box body 20 and the groove 24A of the fitted portion 24 of the other box body 20 are aligned. At this time, the rear surface of the flange portion 28 (specifically, the front side step portion 28 </ b> A) of the other box body 20 is disposed adjacent to the front side of the flange portion 28 of the one box body 20. Accordingly, the flange portion 28 (specifically, the front side step portion 28A) constituting the front end portion of the box body 20 functions as a positioning portion that determines the relative positions of the upper and lower box bodies 20 during nesting.

  Then, the other box body 20 is moved downward from the state shown in FIG. Specifically, the other box body 20 is moved downward while the rear surface of the flange portion 28 (front side step portion 28A) of the other box body 20 is aligned with the front surface of the flange portion 28 of the one box body 20. Let Thereby, the flange part 28 (front side step part 28A) which comprises the front-end part of the box main body 20 functions as a guide part at the time of nesting.

  Then, by lowering the other box body 20 to the position shown in FIG. 10B, the upper end portion of the fitting rib 22 of one box body 20 is inserted into the groove 24A of the other box body 20. At the same time, the upper end surface of the fitting rib 22 contacts the upper end surface of the groove 24A. As a result, the other box body 20 is nested while being supported from below by the fitting ribs 22 of the one box body 20. Then, as shown in FIG. 1B, by repeating the above nesting operation, a plurality of box bodies 20 are nested vertically (in the example shown in FIG. 1B, six box bodies). 20 nesting up and down). Further, when nesting the box body 20, the upper box body 20 is shifted from the lower box body 20 to the front side by a distance L <b> 1 in the front-rear direction between the groove 24 </ b> A and the fitting rib 22. The That is, when nesting the box body 20, it is not necessary to reverse the upper box body 20 back and forth with respect to the lower box body 20, and the upper and lower box bodies 20 are arranged in the same direction. Workability at the time can be improved.

(Assembly to the upper cover 50 of the door 40)
When the door 40 is assembled to the upper cover 50 in a state where the storage box 10 is disassembled, the door 40 is disposed in the door accommodating portion 86 of the door 40. Specifically, the door 40 is disposed substantially parallel to the upper cover 50 so that the rear surface of the door 40 faces the lower surface of the upper cover 50. In this state, the door 40 is arranged so that the hinge portion 42 of the door 40 is positioned between the rear holding claw 82 of the upper cover 50 and the second protruding piece 64. In this state, when the door 40 is brought close to the upper cover 50, the lower end portion of the door 40 comes into contact with the holding hook 82B of the rear holding claw 82, and the rear holding claw 82 is elastically deformed rearward. At this time, the upper end portion of the door 40 comes into contact with the holding hook 84B of the front holding claw 84, and the front holding claw 84 is elastically deformed to the front side.

  When the door 40 is further brought closer to the upper cover 50 from this state, the lower end portion of the door 40 is engaged with the holding hook 82B of the rear holding claw 82, and the upper end portion of the door 40 is held by the holding hook of the front holding claw 84. Engage with 84B. Thereby, the door 40 is assembled | attached to the upper cover 50, and is hold | maintained at the upper cover 50 (refer FIG. 8).

  Here, in the box body 20 of the storage box 10, a fitting rib 22 and a fitted portion 24 that are used when nesting the box body 20 are provided at the lower end portion of the side wall 20 </ b> B of the box body 20. For this reason, the stability of the state where the box body 20 is nested can be ensured.

  That is, the box body 20 is formed in a substantially rectangular parallelepiped box shape opened to the upper side and the front side. For this reason, in the box main body 20, the upper end part of the box main body 20 becomes an open end, and the bending rigidity in the side wall 20B of the box main body 20 becomes comparatively low. Thereby, when an external force acts on the side wall 20B of the box body 20 and the side wall 20B bends in the left-right direction, the upper end portion of the side wall 20B is greatly displaced in the left-right direction. In particular, the amount of displacement of the front end at the upper end of the side wall 20B increases. That is, the box body 20 having a substantially rectangular parallelepiped box shape opened to the upper side and the front side has a structure in which the displacement amount of the upper end portion of the side wall 20B is increased due to the bending deformation of the side wall 20B.

For this reason, when the fitting part and the to-be-fitted part used when nesting the box main body 20 are provided in the upper end part of the side wall 20B of the box main body 20 (hereinafter, this case is referred to as a comparative example), the box There is a possibility that the state when the body 20 is nested becomes unstable.
That is, in the box body 20 of this comparative example, for example, when the side wall 20B of the box body 20 is bent and deformed by an external force, the upper end portion of the side wall 20B is greatly displaced. As a result, in the nesting state, the fitting state between the fitting portion and the fitted portion between the box main bodies 20 may be released. Thereby, for example, when transporting or storing a plurality of box bodies 20 in a nesting state, the state of the nested box bodies 20 may be destroyed.

  For example, in the case of the box body 20 of the comparative example, when the box body 20 is nested in three or more stages, the upper end of the side wall 20B of the box body 20 in the already nested state is in the third or more stage box body 20. It is necessary to fit the upper end of the side wall 20B. In this fitting operation, an external force acts on the upper end of the side wall 20B of the box body 20 in the already nested state from the box body 20 to be newly nested. For this reason, the fitting state of the box bodies 20 in the already nested state may be released. In this case, it is necessary to fit the new box main body 20 to the lower box main body 20 while returning the box main bodies 20 in the non-fitted state to the fitted state again. Therefore, the work when nesting the box body 20 may be complicated.

  On the other hand, in the box body 20 of the present embodiment, the fitting rib 22 and the fitted portion 24 used when nesting the box body 20 are provided at the lower end portion of the side wall 20B of the box body 20. Yes. The lower end of the side wall 20 </ b> B is connected to the bottom wall 20 </ b> A of the box body 20. In other words, in the present embodiment, the fitting rib 22 and the fitted portion 24 are provided in a portion having a relatively small amount of displacement in the side wall 20B. For this reason, when the side wall 20B is bent and deformed, the amount of displacement of the fitting rib 22 and the fitted portion 24 can be significantly reduced compared to the comparative example. Therefore, even if the box body 20 has a substantially rectangular parallelepiped box shape opened to the upper side and the front side, the stability of the state in which the box body 20 is nested can be ensured.

  In the present embodiment, since the upper ends of the side walls 20B of the box body 20 are not fitted to each other as in the comparative example, the nesting is already performed even when the box body 20 is nested in three or more stages. It can suppress that the external force by the new box main body 20 acts on the upper end part of the side wall 20B of the box main body 20 of a state. For this reason, when nesting a new box main body 20 in the nesting box main body 20, it is possible to prevent the fitting state between the already nested box main bodies 20 from being released. Thereby, it can suppress performing the operation | work which returns the box main bodies 20 which became the non-fitting state like the said comparative example to a fitting state again. As a result, the complexity of the work when nesting the box body 20 in three or more stages can be suppressed, and the workability for the user can be improved.

  Moreover, in this Embodiment, the box main bodies 20 can be nested by fitting the upper end part of the fitting rib 22 of one box main body 20 in the groove part 24A of the other box main body 20. FIG. That is, a plurality of box bodies 20 can be nested by groove fitting. Therefore, a plurality of box bodies 20 can be nested with a simple configuration.

  The fitting rib 22 protrudes inward in the width direction of the box body 20 at the lower end portion of the side wall 20B and extends upward from the bottom wall 20A. For this reason, the fitting rib 22 also acts as a reinforcing rib for the side wall 20B. Therefore, the side wall 20B can be reinforced by utilizing the fitting rib 22 used at the time of nesting.

Furthermore, the fitting rib 22 protrudes inward in the width direction of the box body 20. For this reason, the fitting rib 22 can be made invisible from the outside of the storage box 10.
Further, the groove 24A of the fitted portion 24 into which the fitting rib 22 is fitted is exposed to the outside at the lower corner of the box body 20 (the storage box 10). For this reason, in the storage box 10, the groove part 24A exposed to the outside can be disposed at a relatively inconspicuous position.
Furthermore, the vertical groove depth of the groove portion 24 </ b> A is set to be smaller than the vertical dimension of the fitting rib 22. For this reason, the installation area of the groove 24A exposed to the outside of the storage box 10 can be made relatively small.
As described above, the fitting rib 22 and the fitted portion 24 (groove portion 24 </ b> A) can be provided in the box body 20 while ensuring the design of the storage box 10.

  Further, the upper end surface of the fitting rib 22 and the upper end surface of the groove portion 24 </ b> A in the fitted portion 24 are inclined upward as it goes inward in the width direction of the box body 20 in a front view. For this reason, when fitting rib 22 is made to fit in groove part 24A, the upper end surface of fitting rib 22 and the upper end face of groove part 24A contact. Thus, when the plurality of box bodies 20 are nested, the fitting ribs 22 and the groove portions 24A engage in the left-right direction. Therefore, when the fitting rib 22 is fitted in contact with the groove portion 24A, the nesting state is maintained even when a load from above (vertical direction) is applied, and the fitting rib 22 is prevented from buckling. it can. For this reason, the stability of the state where the box body 20 is nested can be further secured. As a result, the fitting state between the fitting rib 22 and the groove 24A can be maintained satisfactorily. Therefore, the stability of the state where the box body 20 is nested can be further ensured.

Further, the upper cover 50 includes a door accommodating portion 86 that accommodates the door 40 disassembled from the box main body 20, and a holding mechanism 80 that retains the door 40. For this reason, in a state where the storage box 10 is disassembled, the door 40 can be held in a state assembled to the upper cover 50.
Thereby, for example, when transporting the storage box 10 in a disassembled state, the packing performance can be improved.
For example, when storing the storage box 10 in a disassembled state when the storage box 10 is not used, the door 40 can be assembled to the upper cover 50 and stored. Thereby, while being able to improve the storage performance of the upper cover 50 and the door 40, it can contribute to prevention of the loss of the door 40. FIG.

  The holding mechanism 80 includes a rear holding claw 82 and a front holding claw 84. The rear holding claw 82 engages with the lower end portion of the door 40, and the front holding claw 84 engages with the upper end portion of the door 40, whereby the door 40 is held by the upper cover 50. Therefore, the door 40 can be held on the upper cover 50 with a simple configuration.

  Further, in the present embodiment, when the upper cover 50 with the door 40 assembled is stacked, the distal end portion of the handle 44 of the door 40 is disposed in the mounting recess 52A of the lower upper cover 50. Thus, the door 40 and the upper cover 50 are configured not to interfere with each other. Therefore, even when the door 40 is held by the upper cover 50, the door 40 can be held by the upper cover 50 while maintaining the stacking performance of the upper cover 50.

  Moreover, in the box main body 20, the support part 30 which supports the door 40 rotatably is provided in the front-end part of 20 A of bottom walls. Further, the support portion 30 is formed in a substantially U shape that is opened downward in a side view, and extends over the entire width direction of the box body 20. Thereby, the front-end part of the box main body 20 can be reinforced using the support part 30 which supports the door 40 rotatably. In other words, the support portion 30 can be used to increase the bending rigidity of the front end portion of the box body 20 and to increase the rigidity of the box body 20 as a whole. As a result, the posture of each box body 20 in the nesting state can be stabilized, and the stability in the state where the box body 20 is nested can be further enhanced.
