Further, the left side frame material 21 is divided into two equal parts, a left front side partial frame material (left side partial frame material) 26 and a left rear side partial frame material (left side partial frame material) 27 at an intermediate portion in the bed length direction. ..
Further, the right side frame material 22 is also divided into two equal parts, a right front side partial frame material (right side partial frame material) 28 and a right rear side partial frame material (right side partial frame material) 29 at the middle portion in the bed length direction.
The lengths of the left front side partial frame material 26, the left rear side partial frame material 27, the right front side partial frame material 28, and the right rear side partial frame material 29 are about 100 cm, and are inside the respective partial frame materials 26 to 29. In order to connect the ends of the corresponding floor material frames 18 with spot bolts, a plurality of receiving plate pieces 40 are projected from each other.

As shown in FIGS. 1, 3 and 4, in the upper bed portion 11, the connecting portion (butting portion) between the adjacent left front side partial frame member 26 and the left rear side partial frame member 27, and the adjacent right front A connecting frame member 30 having a U-shaped cross section is externally fitted to the connecting portion between the side partial frame member 28 and the right rear partial frame member 29 from the outside of the bed, and a plurality of bolts B And nuts N, respectively (see FIGS. 3 and 4). The connection direction between the members by the bolts B and the nuts N here is the vertical direction, but may be, for example, the horizontal direction.

Each connecting frame member 30 is a channel steel having substantially the same length as each partial frame member 26 to 29, and on the upper side of each connecting frame member 30, a fence-shaped side guard for preventing a fall, which is horizontally long over the entire length. 31 are erected respectively. The size of the side guard 31 is 74 cm in length, 24 cm in height, and 3 cm in thickness.
Although each side guard 31 is connected only to the corresponding connecting frame member 30, for example, the side guard 31 is extended in the X1 direction or the X2 direction, and the extension portion thereof is extended. For example, it may be fixed to other parts such as the upper partial support leg 16.

Further, as shown in FIG. 1, four upper partial support legs 16 are bolted to each of the four corners of the support frame 15 with each upper portion arranged above the upper surface of the support frame 15. A total of four triangular plate pieces 32 that support each corner of the support frame 15 downward are arranged near the upper portion of each upper portion support leg 16.
Of the adjacent upper partial support legs 16, a horizontally long head fence (head side fence) 33 is laid horizontally by bolt connection between the upper ends of the two upper partial support legs 16 on the head side. Here, the horizontal frame on the lower side of the head fence 33 also serves as the head side frame material 23.

Next, as shown in FIGS. 1 and 5, the lower bed portion 12 will be described. As described above, here, only the differences that are difficult to infer from the above-mentioned explanation of the upper bed portion 11 will be described.
As shown in FIGS. 1 and 5, in the lower bed portion 12, the connecting portion between the adjacent left front side partial frame member 26 and the left rear side partial frame member 27, and the adjacent right front side partial frame member 28 and the right A connecting frame member 30A having no side guard 31 is connected to the connecting portion with the rear side partial frame member 29 by a plurality of bolts in a state of being exteriorized from the outside of the bed.

Further, on the lower side of the foot side frame member 24, a horizontally long foot fence 34 arranged below the floor member 14 is laid horizontally. A short lower partial ladder 35B of the ladder 13 is fixed to the central portion of the foot fence 34. Of each lower partial ladder 35B, the lower end portions of the pair of left and right handrail frames 13a of the upper partial ladder 35A made of metal pipes are fitted to the upper end portions protruding upward from the foot side frame member 24, respectively. .. The upper end portions of these handrail frames 13a are bolted to the intermediate portions of the foot side frame member 24 of the upper bed portion 11 in the length direction. The lower frame of the foot fence 34 may be omitted.

A total of four triangular plate pieces 32 on which the floor member 14 of the lower bed portion 12 is supported are arranged near the lower portion of the corresponding lower partial support leg 36.
Further, the head fence 33 of the lower bed portion 12 is bolted slightly above the fixed position of each triangular plate piece 32 among the two lower partial support legs 36 on the head side.
Further, the four lower partial support legs (partial support legs) 36 constituting the lower part of each support leg P are respectively fitted and connected to the lower end portions of the corresponding upper partial support legs 16. The height (length) of each lower partial support leg 36 is 77 cm. On the other hand, the height of each upper partial support leg 16 is 78 cm.
Further, at the ends of the left side frame members 21 of the upper and lower bed portions 11 and 12 on the X1-X2 side, two braces 37 having a length adjusting function are laid horizontally in an intersecting state. As a result, the connection strength of the upper and lower bed portions 12 is increased.

All the above-mentioned bed parts are stored separately in two corrugated cardboard boxes (packing boxes) 38 and 39, which are more compact than the conventional products, and constitute an assembly type bunk bed package 50 (FIG. 6). reference).
The size of one cardboard box 38 is 100 cm in length, 52 cm in width, and 27 cm in height. In the cardboard box 38, four partial floor members 17 and four upper and lower partial support legs 16 and 36 are housed.
The size of the other cardboard box 39 is 113 cm in length, 50 cm in width, and 20 cm in height. The corrugated cardboard box 39 contains all the remaining parts of the bunk bed 10 (including the brace 37) except for the floor member 17 of each branch and the upper and lower partial support legs 16 and 36. ..
Since the method of using the bunk bed 10 of the first embodiment is general, the description thereof will be omitted here.

As described above, the bunk bed 10 is a left front side portion in which the lengths of the left and right frame members 21 and 22, which are long parts of the upper and lower bed portions 11 and 12, are halved. It is composed of a frame member 26 and a left rear partial frame member 27, and is composed of four partial floor members 17 in which the floor member 14 is equally divided in the bed length direction, while the four support legs P are on the upper side and the lower side, respectively. Since it is composed of partial support legs 16 and 36, the prefabricated bunk bed 10 can be packed smaller than the conventional product (general conventional cardboard box size is 190 cm or more in length, 50 cm or more in width, 10 cm or more in height). ). As a result, the storage space of the corrugated cardboard boxes 38 and 39 can be made compact and the transportation cost can be reduced.

Further, when assembling the bed, the upper and lower bed portions 11 and 12 correspond to the connecting portions of the adjacent left front and rear partial frame members 26 and 27 and the connecting portions of the right front and rear partial frame members 28 and 29. The left and right frame members 21 and 22 are assembled by exteriorizing and connecting the connecting frame members 30 and 30A having a U-shaped cross section from one side of the bed.

At that time, as shown in FIGS. 3 to 5, of the U-shaped connecting frame members 30 and 30A, the upper plate 30a long in the X1-X2 direction corresponds to the left front and rear partial frame members. While the upper plates 26a and 27a of the connecting portions of 26 and 27 are in contact with each other, the intermediate plate 30b long in the X1-X2 direction of the connecting frame members 30 and 30A corresponds to the left front and rear partial frame members. The outer plates 26b and 27b of the connecting portions of 26 and 27 are in contact with each other. Further, of the connecting frame members 30 and 30A, the lower plates 30c long in the X1-X2 direction come into contact with the lower plates 26c and 27c of the connecting portions of the corresponding left front and rear partial frame members 26 and 27, respectively. (The same applies to the connecting portions of the right front and rear partial frame members 28 and 29).

As a result, the left and right frame members 21 and 22, which are divided into two front and rear partial side frame members 26-27 and 28-29, respectively, can be accurately inserted into, for example, the corresponding ends of the left and right partial frame members. The connecting work is easier and more robust than the case of using a tubular connecting member that requires (2 actions) or a flat plate-shaped connecting member that may be misaligned during the connecting work or lack of connecting strength. These can be connected and assembled.

Further, since the side guard 31 for fall prevention is provided on each connecting frame member 30 for the upper bed portion, it accidentally falls from the upper bed portion 11 at bedtime, for example, when the user turns over. Can be prevented from doing so.
Further, since the maximum length of each side of the corrugated cardboard boxes 38 and 39 is set to 113 cm, the size difference from the conventional corrugated cardboard boxes 38 and 39 becomes remarkable.

This idea is useful as a technique for a bunk bed having an upper bed, a lower bed, and a ladder.
