FIG. 2 is a plan view of the parts of the bed A in the present embodiment. As shown in the figure, the bed A in the present embodiment includes four types of members, a vertical plate member 31, a horizontal plate member 32, a cover member 4, and a top plate member 5, and a case C (see FIG. 4) for accommodating the four types of members. Consists of only. The vertical plate member 31, the horizontal plate member 32, the cover member 4, and the top plate member 5 are all made of corrugated cardboard and have substantially the same thickness, which is about 6 mm in the present embodiment.

The vertical plate member 31 is a substantially rectangular plate-shaped member, and in the present embodiment, the length is 620 mm × 315 mm. Four slits 31a are formed at predetermined intervals on the long side of one of the vertical plate members 31 (lower side in the drawing). In the present embodiment, the distance between the slits 31a is 119 mm. The width of the slit 31a is substantially the same as the thickness of the corrugated cardboard, and the depth is 158 mm.

Similarly, the horizontal plate member 32 is also a substantially rectangular plate-shaped member, and in the present embodiment, it is 690 mm × 315 mm. Four first slits 32a are formed at predetermined intervals on the long side of one of the horizontal plate members 32 (upper side in the drawing). In the present embodiment, the distance between the first slits 32a is 95 mm. The width of the first slit 32a is substantially the same as the thickness of the corrugated cardboard, and the depth thereof is 158 mm. Further, the horizontal plate member 32 is formed with a pair of second slits 32b so as to sandwich the four first slits 32a. In the present embodiment, the distance between the second slit 32b and the first slit 32a is about 94.5 mm, and the depth of the second slit 32b is 198 mm. The lower width of the second slit 32b is substantially the same as the thickness of the corrugated cardboard, but the upper end of the second slit 32b has a widened portion 32c having a width approximately twice the thickness of the corrugated cardboard (example of the receiving portion in the present invention). Is formed. The depth of the widening portion 32c is 80 mm, which is substantially the same as the height of the upper insertion portion 45 of the cover member 4 and the height of the insertion portion 52 of the top plate member 5, which will be described later.

Although the details will be described later, the load support unit 3 that supports the load of the user is formed by combining the four vertical plate members 31 and the four horizontal plate members 32 in a grid shape (see FIG. 4 (b)). ..

The cover member 4 has a sideboard 41 having substantially the same size as the vertical plate member 31, laterally folded portions 42 formed on both sides of the sideboard 41, and lateral differences formed on the sides of the respective laterally folded portions 42. The insertion portion 43, the upper folding portion 44 formed on the upper side of the sideboard 41 (corresponding to the folding portion in the present invention), and the upper insertion portion 45 formed on the upper side of the upper folding portion 44 (reinforcing difference in the present invention). It is composed of (corresponding to the embedding part) and. Further, two slits 43a are formed on the lower side of each lateral insertion portion 43. The width of the slit 43a is also substantially the same as the thickness of the corrugated cardboard, and the depth is 118 mm. The distance between the slits 43a is the same as the distance between the slits 31a of the vertical plate member 31. The width of the lateral insertion portion 43 is 1/2 of the width of the sideboard 41, and the distance from the side end of each lateral insertion portion 43 to the slit 43a on the side end side is the distance of the slit 31a of the vertical plate member 31. It is 1/2 of the interval and the interval of the slit 43a of the lateral insertion portion 43. Therefore, when the cover member 4 is bent and formed as shown in FIG. 5A, the two lateral insertion portions 43 are adjacent to each other, and the arrangement of the four slits 43a is the arrangement of the slits 31a of the vertical plate member 31. Is the same as. In addition, "upper" here means "upper" in the state where the cover member 4 is in the posture of FIG. 2, that is, in the state where the sideboard 41 is upright.

FIG. 3 is a sectional view taken along line III-III in FIG. As shown in the figure, when the vertical plate member 31 is cut along such a cross-sectional line and viewed from above in the figure, the corrugated shape of the corrugated cardboard flute F can be visually recognized. The same applies to the horizontal plate member 32 and the cover member 4. By using corrugated cardboard in such a direction, the load bearing performance can be improved.

The top plate member 5 is a rectangular plate-shaped member, and in the present embodiment, the size is 950 mm × 660 mm. The top plate member 5 is composed of a rectangular top plate 51 and insertion portions 52 formed at both ends of the top plate 51 in the vertical direction in the drawing. In the present embodiment, the vertical length (left-right direction in the figure) of the top plate 51 and the vertical length of the insertion portion 52 are the same, and both are about 1.5 times the vertical length of the load support unit 3. .. The length of the insertion portion in the lateral direction (vertical direction in the figure) is 80 mm.

Next, the method of assembling the bed A in the present embodiment will be described with reference to FIGS. 4 and 5. First, the four horizontal plate members 32 are arranged so as to have a predetermined interval (the interval between the slits 31a of the vertical plate member 31) and the first slit 32a to open upward. Then, the vertical plate member 31 is inserted from above so that each slit 31a fits with the first slit 32a of each horizontal plate member 32 (FIG. 4A). As a result, the load support unit 3 in which the four horizontal plate members 32 and the four vertical plate members 31 as shown in FIG. 4B are combined in a grid shape is formed.

Next, the cover member 4 is bent and formed (FIG. 5A). Specifically, the laterally folded portions 42 formed on both sides of the sideboard 41 are folded back 90 ° toward the inside (the side arranged toward the load support unit 3, the front side of the paper in FIG. 5). Then, the lateral insertion portion 43 connected to each lateral folding portion 42 is further folded inward by 90 °. As a result, the sideboard 41, the laterally folded portion 42, and the laterally inserted portion 43 form a substantially rectangular shape in a plan view. Further, the upper folded portion 44 is folded inward by 90 °, and the upper insertion portion 45 is folded inward by 90 °.

The cover member 4 bent and formed in this way is attached to the load support unit 3 (FIG. 4 (c)). Specifically, the sideboard 41 is parallel to the vertical plate member 31, and the lateral insertion portion 43 is on the load support unit 3 side, and the slit 43a of the horizontal insertion portion 43 and the second slit of the horizontal plate member 32. The cover member 4 is inserted from above the load support unit 3 so that the 32b and the 32b are fitted to each other. At this time, the upper insertion portion 45 is inserted into the widening portion 32c of the second slit 32b of the horizontal plate member 32. The cover member 4 is attached to both lateral sides of the load support unit 3 to form the main body unit 11 (FIG. 4 (d)). By covering the lateral side portion of the load support unit 3 with the cover member 4 in this way, the strength of the lateral side portion of the load support unit 3 can be increased.

Three sets of such main body units 11 (main body units 11a, 11b, 11c) are assembled and arranged side by side so that the sideboards 41 of each other are continuous. At that time, the horizontal plate member 32 is sandwiched between the adjacent main body units 11 (FIG. 4 (e)). By arranging the horizontal plate member 32 in this way, the strength of the proximity portion of the main body unit 11 can be increased.

Next, the insertion portion 52 of the top plate member 5 is bent downward by 90 ° (FIG. 5 (b)). Then, the top plate member 5 is covered from above the main body 1 so that the insertion portion 52 is inserted into the widening portion 32c of the second slit 32b of the horizontal plate member 32 of the load support unit 3. Specifically, the top plate member 5a is covered so that the top plate 51a covers the entire main body unit 11a and the front half of the main body unit 11b, and the top plate 51b covers the rear half of the main body unit 11b and the entire main body unit 11c. Is covered with the top plate member 5b (FIG. 4 (f)). In the present embodiment, the vertical length of the top plate 51 and the insertion portion 52 is about 1.5 times the vertical length of the main body unit 11. Therefore, the two top plate members 5a and 5b having the same shape can cover the upper part of the main body 1 composed of the three main body units 11.

By arranging the top plate members 5a and 5b in this way, the insertion portion 52 of each top plate member 5 is inserted into the widening portion 32c of the plurality of second slits 32b formed in the adjacent main body units 11. Specifically, the insertion portion 52a of the top plate member 5a is formed into a widening portion 32c of all the second slits 32b of the main body unit 11a and a widening portion 32c of the second slit 32b of the front half of the main body unit 11b. It is plugged in. On the other hand, the insertion portion 52b of the top plate member 5b is inserted into the widening portion 32c of the second slit 32b in the rear half of the main body unit 11b and the widening portion 32c of all the second slits 32b of the main body unit 11c. As a result, the top plate member 5 can be fixed to the main body 1 and the adjacent main body units 11 can be prevented from being separated. Further, even if a lateral displacement force acts on the main body 1 due to turning over or the like, the insertion portion 52 supports the force as a surface, so that it is possible to prevent the adjacent main body units 11 from separating. Further, since the two insertion portions 52 are inserted in the vicinity of the respective ends in the lateral direction, a larger force can be supported. Further, as in the present embodiment, the strength of the insertion portion 52 can be increased by integrally forming the insertion portion 52 with the top plate 51. Further, the upper insertion portion 45 of the cover member 4 inserted into the widening portion 32c of the second slit 32b together with the insertion portion 52 acts to increase the strength of the insertion portion 52.

Finally, the case C is used as the headboard 2 and stands on the front side of the main body 1 (FIG. 4 (g)). As a result, the bed A shown in FIG. 1 is completed.

As described above, the bed A according to the present embodiment is composed of only four types of members and a case C for accommodating them, and can be assembled only by bending and inserting.
