2. Functions of Bed 1 Functions of the bed 1 will be described with reference to FIGS. 2 to 10. FIG. When using the bed 1, the state of the bed 1 is the extended state, as shown in FIG. In the extended state, the angles α and β shown in FIG. 4 are close to 90 degrees, and the angle γ is close to 180 degrees. Also, when in the extended state, the horizontal plate 9 is in a flat state, as shown in FIGS. That is, the horizontal plate 9 is not mountain-folded at the mountain-folded portion 12 and is not valley-folded at the upper end 11 . When in the extended state, the mutual spacing of the longitudinal plates 7a-7g is widened.

Further, when in the stretched state, the partition plates 35a to 35f are not bent at the folding lines 41, 43, 45 and 47, as shown in FIG.
When the bed 1 is stored or transported, the bed 1 can be in a contracted state (hereinafter referred to as contracted state) in the direction L as shown in FIGS. 9-10. In the contracted state, the distance between the vertical plates 7a-7g is reduced.

When in the contracted state, the first side plate 13 and the second side plate 15 are folded in a bellows shape, as shown in FIGS. That is, in the contracted state, the first side plate 13 and the second side plate 15 are valley-folded at the connecting portion 31 and mountain-folded at the end portion 17 . When in the contracted state, the angles α, β, γ shown in FIG. 4 are each acute angles.

Further, in the contracted state, the horizontal plate 9 is folded in a bellows shape as shown in FIG. That is, in the contracted state, the horizontal plate 9 is mountain-folded at the mountain-folded portion 12 and valley-folded at the upper end 11 .

Further, in the contracted state, the partition plates 35a to 35f are folded in a bellows shape as shown in FIG. That is, in the contracted state, fold line 41, fold lines 43 and 45, and fold line 47 are alternately folded in opposite directions.

By applying a compressive force in the direction L to the bed 1 in the extended state, the state of the bed 1 can be changed to the compressed state. Further, by applying a force in the direction L to expand the bed 1 in the compressed state, the state of the bed 1 can be changed to the expanded state.

3. Effects of Bed 1 (3-1) Only by applying force in the direction L to compress bed 1 in the extended state, the state of bed 1 can be changed to the compressed state. In addition, the state of the bed 1 can be changed to the extended state simply by applying a force in the direction L to extend the bed 1 in the compressed state. Therefore, the bed 1 can be expanded and contracted in a short time.
(3-2) The bed 1 includes a connecting portion 31 where the first side plate 13 and the second side plate 15 are connected. In the connecting portion 31 , the second side plate 15 is inserted into the first groove 27 and the first side plate 13 is inserted into the second groove 29 . By providing the connecting portion 31, the first side plate 13 and the second side plate 15 can rotate so that the angle γ changes. As a result, the bed 1 can expand and contract with a simple structure.

(3-3) The bed 1 has partition plates 35a to 35f. The partition plates 35a-35f are inserted into the grooves 33 of the vertical plates 7b, 7d and 7f and extend along the direction L. As shown in FIG. Since the bed 1 is provided with the partition plates 35a to 35f, the compressive strength in the vertical direction is further increased.

(3-4) The bed 1 is made of cardboard. Therefore, it is easy to manufacture the bed 1 .
4. Other Embodiments Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and various modifications can be made.

(4-1) The horizontal plate 9 may be connected to the lower ends of the vertical plates 7a to 7g.
(4-2) The bed 1 may be made of a material other than cardboard.
(4-3) The number of units 19a to 19f included in one bed 1 may be other than six.

(4-4) The bed 1 may not be composed of the units 19a to 19f.
(4-5) The form of the connecting part 31 may be another form. For example, as shown in FIG. 11 or 12 , the first side plate 13 has slit holes 55 . The second side plate 15 has projections 57 that can be inserted into the slit holes 55 . By inserting the protrusion 57 into the slit hole 55, the first side plate 13 and the second side plate 15 are connected. The slit hole 55 and the projecting portion 57 constitute the connecting portion 31 . The slit holes 55 correspond to grooves or holes formed in the first side plate 13 . The projecting portion 57 corresponds to the fitting portion.
The slit hole 55 is formed, for example, in the center of the first side plate 13 in the vertical direction. The slit hole 55 does not reach the end of the first side plate 13, for example. The slit hole 55 extends vertically, for example. The protruding portion 57 has a length approximately equal to the length of the slit hole 55, for example. The protrusion 57 has, for example, a groove 59 at its base. The groove 59 may be provided on both the upper side and the lower side of the protrusion 57 as shown in FIG. 11, or may be provided on either the upper side or the lower side of the protrusion 57 as shown in FIG. may be provided. When the protrusion 57 is inserted into the slit hole 55 , at least one of the lower end and the lower end of the slit hole 55 is inserted into the groove 59 . In this case, the projecting portion 57 is difficult to come off from the slit hole 55 .
Further, for example, the protrusion 57 has a shape that is wider on the tip side than on the root side. When the first side plate 13 and the second side plate 15 are connected, the distal end portion of the protrusion 57 passes through the slit hole 55 . Since the tip side is wider than the base side, the protruding portion 57 is difficult to slip out of the slit hole 55 .
Alternatively, the second side plate 15 may have the slit hole 55 and the first side plate 13 may have the protrusion 57 .
(4-6) A function of one component in each of the above embodiments may be assigned to a plurality of components, or a function of a plurality of components may be performed by one component. Also, part of the configuration of each of the above embodiments may be omitted. Also, at least part of the configuration of each of the above embodiments may be added, replaced, etc. with respect to the configuration of the other above embodiments.

(4-7) In addition to the bed 1 described above, the present disclosure can also be implemented in various forms such as a system having the bed 1 as a component, a bed manufacturing method, a bed preparation kit, and the like.
