The pair of recesses 655 are arranged at a distance in the vertical direction and have the same size and shape. In addition to being open to one side in the left-right direction, each recess 655 is also open to the front-rear direction. Hereinafter, one side in the left-right direction to which each recess 655 is open is referred to as the first side in the left-right direction, and the opposite side is referred to as the second side in the left-right direction.

The end surface of the first side in the left-right direction of the main body 65 is formed as a contact surface 650 for contacting the inner surface of the back recess 5. The contact surface 650 contacts the inner surface of the outer recess 51 that constitutes a part of the back recess 5, and more specifically, contacts the inner surface of the first outer recess 511 or the second outer recess 512.

In the first embodiment of the box 9, the contact surface 650 of the main body 65 includes an end surface of a rib 653 protruding toward the first side in the left-right direction. The ribs 653 are provided in plurality at intervals in the vertical direction. The plurality of ribs 653 are four ribs 653 provided in parallel with each other at intervals in the vertical direction. Each rib 653 has a shape extending in a straight line in the front-rear direction.

The four ribs 653 are composed of two ribs 653 located at both ends of the main body 65 in the up-down direction, and another two ribs 653 located between a pair of recesses 655 in the up-down direction. The end faces of the four ribs 653 have a concave curved surface shape. The shapes of the end faces of the four ribs 653 are the same. That is, the contact surface 650 of the main body 65 formed by the end faces of the four ribs 653 has a concave curved surface shape along the inner side surface of the convex curved surface of the outer recess 51.

As shown in FIG3 and other figures, when the reinforcing member 6 is inserted into the first outer recess 511, the contact surface 650 of the main body 65 of the reinforcing member 6 contacts the convex curved portion of the inner surface of the first outer recess 511.

The end faces of the ribs 653 have a shape along the convex curved surface of the second rear convex portion 42. The convex curved surface of the second rear convex portion 42 is a surface that is curved in a circular arc shape in a horizontal cross section.

Furthermore, when the reinforcing member 6 is inserted into the first outer recess 511 , one of the plurality of ribs 45 provided on the second rear face protrusion 42 is inserted into one of the pair of recesses 655 of the reinforcing member 6 (see FIG. 2 ).

The reinforcing member 6 is embedded between a pair of upper and lower ribs 516 provided in the first outer recess 511. The pair of ribs 516 are ribs protruding from the inner side surface of the first frame 31 of the outer frame 3 (see FIG. 4 ). The pair of ribs 516 are ribs extending straight in the front-rear direction and are parallel to each other. Each rib 516 is provided so that the protrusion from the outer frame 3 increases toward the back direction.

When the reinforcing member 6 is inserted into the first outer recess 511, the reinforcing member 6 is pressed between the pair of ribs 516. In addition, the main body 65 of the reinforcing member 6 is pressed and fixed between the first frame 31 and the second rear protrusion 42 (i.e., the first outer recess 511).

When the reinforcing member 6 is inserted into the second outer recess 512, the contact surface 650 of the main body 65 of the reinforcing member 6 contacts the convex curved portion of the inner surface of the second outer recess 512. The contact surface 650 of the main body 65 has a shape along the convex curved portion of the inner surface of the second outer recess 512.

In more detail, when the reinforcing member 6 is inserted into the second outer recess 512, the end faces of the four ribs 653 included in the main body 65 respectively abut against the convex curved side faces of the third rear protrusion 43. The end faces of the ribs 653 have a shape along the convex curved surface of the third rear protrusion 43. The convex curved surface of the third rear protrusion 43 is a surface that is curved in a circular arc shape in a horizontal cross section, similar to the second rear protrusion 42.

Furthermore, when the reinforcing member 6 is inserted into the second outer recess 512 , one of the plurality of ribs 45 provided on the third rear surface protrusion 43 is inserted into one of the pair of recesses 655 of the reinforcing member 6 .

The reinforcing member 6 is embedded between a pair of upper and lower ribs 517 provided in the second outer recess 512. The pair of ribs 517 are ribs protruding from the inner side surface of the second frame 32 of the outer frame 3. The pair of ribs 517 are ribs extending straightly in the front-rear direction and are parallel to each other.

When the reinforcing member 6 is inserted into the second outer recess 512, the reinforcing member 6 is pressed between the pair of ribs 517. In addition, the main body 65 of the reinforcing member 6 is pressed and fixed between the second frame 32 and the third rear protrusion 43 (i.e., the second outer recess 512).

(Abutment portion) The abutment portion 61 of the reinforcement member 6 is a portion that abuts against the inner side surface of the outer frame 3. In one embodiment of the box 9, a plurality of ribs 67 protruding from the main body 65 toward the second side in the left-right direction constitute the abutment portion 61 (see FIGS. 5 and 6).

The plurality of ribs 67 are four ribs 67 which are arranged in parallel with each other at intervals in the up-down direction. Each rib 67 has a straight line shape extending in the front-rear direction.

The flat surfaces of the protruding ends of the four ribs 67 constitute abutting surfaces 610 that abut against the inner side surface of the outer frame 3. More specifically, the abutting surfaces 610 abut against the inner side surface of the first frame 31 or the second frame 32.

The four ribs 67 constituting the contact portion 61 correspond one-to-one to the four ribs 653 provided on the main body 65. The main body 65 is provided with four flat plate-shaped connecting portions 68 for connecting the one-to-one corresponding ribs 653 and 67 to each other. The four connecting portions 68 each in the form of a plate are arranged parallel to each other at intervals in the vertical direction.

The four ribs 67 are arranged so that the protrusion from the main body 65 increases as they are disposed toward the back. The protruding end surfaces of the four ribs 67 (i.e., the contact surfaces 610) are slightly inclined so that when the reinforcing member 6 is inserted into the outer recess 51, the outer frame 3 is pushed outward.

As shown in FIG. 3 and other figures, when the reinforcing member 6 is inserted into the first outer recess 511, the contact surface 610 of the contact portion 61 of the reinforcing member 6 contacts the flat inner surface of the first frame 31.

When the reinforcing member 6 is inserted into the second outer recess 512, the contact surface 610 of the contact portion 61 of the reinforcing member 6 contacts the flat inner surface of the second frame 32. Specifically, the surfaces of the protruding ends of the four ribs 67 slide against the inner surface of the second frame 32, push the second frame 32 slightly outward, and correct the shape of the second frame 32.

1-3. Effects In the first embodiment of the box 9, the box body 1 can be effectively reinforced by inserting a small reinforcement member 6 into the box body 1 formed using a resin sheet, and the shape of the box body 1 can be corrected. Therefore, an effectively reinforced and shape-corrected box 9 can be obtained without requiring a large member as in the prior art.

In the cabinet 9 of the first embodiment, since it is not necessary to provide a large-scale reinforcing rib on the cabinet body 1, the design freedom of the cabinet body 1 can be improved.

The reinforcing member 6 of the first embodiment can also be installed on a cabinet body 1 of a different size from the cabinet body 1 of the first embodiment. By using the reinforcing member 6 in common for cabinet bodies 1 of different sizes, cost reduction can be achieved.

2. Second Implementation

The cabinet 9 of the second embodiment is described based on Figures 7 to 10. In addition, the same symbols are given to the same components as those of the above-mentioned embodiment, and detailed descriptions are omitted.

In the cabinet 9 of the second embodiment, a reinforcing member 6 of a different embodiment is inserted into the cabinet body 1 having the same structure as that of the first embodiment.

The reinforcing member 6 included in the box 9 of the second embodiment includes a contact portion 62 in addition to the main body portion 65 and the contact portion 61 .

In the following description of the cabinet 9 according to the second embodiment, the abutting portion 61 of the reinforcing member 6 is referred to as a first abutting portion 61 , and the abutting portion 62 is referred to as a second abutting portion 62 .

The main body 65 is a portion of the reinforcing member 6 that contacts the back recess 5, more specifically, a portion that contacts the first outer recess 511 or the second outer recess 512 of the outer recess 51. The contact portion 61 is a portion of the reinforcing member 6 that contacts the inner surface of the outer frame 3.

In the second embodiment of the box 9, the portion protruding from the main body 65 to the first side in the left-right direction (i.e., one side in the left-right direction where each recess 655 of the main body 65 is open) constitutes the second contact portion 62. The second contact portion 62 is a convex sheet-shaped portion extending linearly in the left-right direction, and has a contact surface 620 along the shape of the surface 40 of the rear convex portion 4.

The second contact portion 62 is located on the opposite side of the first contact portion 61 across the main body 65. The second contact portion 62 protrudes from a portion of the main body 65 located between a pair of recesses 655 in the vertical direction toward a first side in the left-right direction.

As shown in Fig. 10, the two ribs 653 and the second contact portion 62 located between the pair of recesses 655 in the vertical direction are continuous with each other. The concave curved end surfaces of the two ribs 653 (i.e., the concave curved contact surfaces 650 of the main body 65) are smoothly continuous with the flat contact surface 620 of the second contact portion 62.

The contact surface 620 of the second contact portion 62 is a flat surface that contacts the surface 40 of the rear convex portion 4 , and more specifically, is a flat surface that contacts the surface 420 of the second rear convex portion 42 or the surface 430 of the third rear convex portion 43 .

The second contact portion 62 having a rectangular flat plate shape is provided with a buckle portion 625. The buckle portion 625 is buckled with a portion of the rear protrusion 4, more specifically, with a buckle body 423 constituting a portion of the second rear protrusion 42, or with a buckle body 433 constituting a portion of the third rear protrusion 43. The buckle body 423 of the second rear protrusion 42 and the buckle body 433 of the third rear protrusion 43 both have a cylindrical boss shape.

The buckle portion 625 of the reinforcing member 6 includes: a hole 626 penetrating the second abutting portion 62 in the front-rear direction, and a plurality of ribs 627 protruding from the inner circumferential surface of the hole 626.

The contact surface 610 of the first contact portion 61 of the reinforcing member 6 (i.e., the surface of the protruding ends of the four ribs 67 constituting the first contact portion 61) contacts the inner surface of the first frame 31. The contact surface 620 of the second contact portion 62 of the reinforcing member 6 contacts the flat surface 420 of the second rear convex portion 42 facing the rear direction.

In addition, the convex buckle body 423 protruding from the surface 420 of the second rear convex portion 42 is inserted into the buckle portion 625 of the second abutting portion 62. The front ends of the plurality of ribs 627 included in the buckle portion 625 abut against the outer peripheral surface of the convex buckle body 423. That is, the buckle body 423 of the second rear convex portion 42 is pressed into the buckle portion 625 of the second abutting portion 62, thereby more firmly fixing the reinforcing member 6. In the present invention, the so-called pressing includes mutual engagement and stopping, that is, includes buckling.

When the reinforcing member 6 is inserted into the second outer recess 512, the contact surface 650 of the main body 65 of the reinforcing member 6 contacts the convex curved portion of the second outer recess 512. The contact surface 610 of the first contact portion 61 of the reinforcing member 6 contacts the inner surface of the second frame 32. The contact surface 620 of the second contact portion 62 of the reinforcing member 6 contacts the flat surface 430 of the third rear convex portion 43 facing the rear direction.

In addition, the convex buckle body 433 protruding from the surface 430 of the third rear convex portion 43 is inserted into the buckle portion 625 of the second abutting portion 62. The front ends of the plurality of ribs 627 included in the buckle portion 625 abut against the outer peripheral surface of the convex buckle body 433. That is, the buckle body 433 of the second rear convex portion 42 is pressed into the buckle portion 625 of the second abutting portion 62, thereby more firmly fixing the reinforcing member 6.

Furthermore, the buckle portion 625 of the second contact portion 62 may be shaped like a convex hub, instead of the buckle bodies 423 and 433 of the rear convex portion 4 having a convex hub shape. In this case, the buckle bodies 423 and 433 of the rear convex portion 4 include, for example, a hole and a plurality of ribs protruding from the inner circumference of the hole. That is, as long as one of the buckle bodies 423 and 433 of the rear convex portion 4 and the buckle portion 625 of the second contact portion 62 has a convex hub shape, the other has a rib for being pressed in and fixed.
