Description

[Technical Field]

[0001] The present invention relates to a bed, and more particularly to a technology that allows for easy assembly and compact packing. [Background technology]

[0002] A bed frame is composed of a bed base, which is a frame formed in a roughly rectangular shape in plan view so that a mattress or other item can be placed on top, and multiple leg members that are connected to the bed base and support the floor. In most cases, the components that make up the bed base and the leg members are separated into multiple parts, and the parts are packaged separately, requiring the purchaser to assemble the parts themselves after purchase. Many people are not accustomed to assembling wooden components, and assembly takes a long time. In addition, assembly often requires specialized tools, which are no longer needed once assembled and must be discarded, which is not environmentally friendly.

[0003] Therefore, a unit-type bed frame as described in Patent Document 1 has been proposed as a bed frame of a type in which pre-assembled units are connected (Patent Document 1).

[0004] According to the modular bed frame described in Patent Document 1, three small bed frames divided into three longitudinal sections are lined up and connected with connecting metal fittings, and a wooden slatted base is then placed on top to form the bed frame. In this case, the bed base body and leg members are formed integrally with the small bed frame, so there is no need to connect the bed base body and leg members with tools, making assembly easy.

[0005] However, in the bed frame disclosed in Patent Document 1, the leg members extending vertically downward from the bed base body are configured integrally with the bed base body, making it difficult to pack the bed in a size smaller than the length of the legs. In particular, when storing a storage box such as a clothing case below the bed frame, the leg members must be made somewhat longer, which results in a larger package.

[0006] [Patent Document 1] Registered Utility Model No. 3080974 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has been made in view of these problems, and aims to provide a bed that can be easily assembled and packed compactly. [Means for solving the problem]

[0008] The present invention provides the following solutions:

[0009] The bed according to the first aspect comprises a first bed body and a second bed body that are rectangular in plan view, and ends of the first bed body and the second bed body are rotatably connected to each other using hinge members, and the bed body can be switched between a first position in which the first bed body and the second bed body are stacked on top of each other and a second position in which they are arranged side by side; a plurality of front and rear leg members that are detachably attached to both ends of the underside of the bed body in the longitudinal direction and serve as support legs for the installation surface; and a plurality of front and rear leg members that are detachably attached between the front and rear leg members in the longitudinal direction of the underside of the bed body. The bed frame includes an intermediate leg member having a fixing screw portion for screwing onto the bed base body, and a connecting plate made of a flat plate and arranged to straddle the first bed base body and the second bed base body in the second posture, the connecting plate having a first insertion hole portion through which the fixing screw portion of the intermediate leg member can be inserted, and a first screw hole portion into which the fixing screw portion of the intermediate leg member can be screwed at a position corresponding to the first insertion hole portion when the connecting plate is arranged to straddle the first bed base body and the second bed base body.

[0010] According to the first aspect of the invention, the bed includes a first bed platform body and a second bed platform body, each rectangular in plan view, whose ends are rotatably connected to each other using hinges and switchable between a first position where they are stacked and a second position where they are arranged side by side. This allows the bed platform body to be stacked in the first position for compact packaging. When assembled, the first bed platform body and the second bed platform body are placed in the second position, and a connecting plate is fixed to the bed platform body across the first and second bed platform bodies to maintain the second position. The flat connecting plate supports the weight of the first and second bed platform bodies, allowing the bed platform body to be stably fixed in the second position. Furthermore, the fixing screw portion of the intermediate leg member is inserted into the first insertion hole of the connecting plate and threaded into the first screw hole, thereby fixing the connecting plate in close contact with the underside of the bed platform body. Therefore, simply by inserting the fixing screw portion into the first insertion hole and manually turning the intermediate leg member to thread it into the first screw hole, the intermediate leg member itself can be fixed and the bed platform body can be stably maintained in the second position at the same time.

[0011] The bed according to the second feature is the bed according to the first feature, wherein the intermediate leg members are provided at two locations on either side of the center line in the width direction of the bed base body, one intermediate leg member being provided on the first bed base body and the other intermediate leg member being provided on the second bed base body.

[0012] According to the second feature of the invention, by providing two intermediate leg members, the bed body is supported by a total of six leg members, including two sets of front and rear leg members provided at the front and rear ends of the bed body. This allows space to be secured below the bed body for storing clothing cases, etc. Furthermore, by providing one of the two intermediate leg members on the first bed body and the other on the second bed body, the bed body can be supported in a balanced manner.

[0013] A bed according to a third feature is a bed according to the first or second feature, further comprising a fixing bolt having a bolt portion for screwing into the bed base body, wherein the connecting plate is formed with a first insertion hole portion and a second insertion hole portion, through which the bolt portion of the fixing bolt is inserted, in line, and the underside of the bed base body is provided with a second screw hole portion, through which the bolt portion is screwed, at a position corresponding to the second insertion hole portion.

[0014] According to the invention relating to the third feature, by inserting the fixing bolt into the second insertion hole portion of the connection plate and screwing it into the second threaded hole portion, the connection plate can be pressed against the bed base body not only by fastening with the intermediate leg member but also by the fixing bolt, so that the connection plate can be more firmly fixed to the bed base body and a more stable second posture can be maintained.

[0015] The bed according to the fourth feature is the bed according to the third feature, wherein a first screw hole portion is formed on the underside of one of the first bed base body or the second bed base body, and a second screw hole portion is formed on the underside of the other of the first bed base body or the second bed base body.

[0016] According to the invention relating to the fourth feature, by screwing the fixing screw portion of the intermediate leg member into a first threaded hole portion formed in one of the first bed base body or the second bed base body, and screwing the bolt portion of the fixing bolt into a second threaded hole portion formed in the other of the first bed base body or the second bed base body, it is possible to connect the two bed base bodies across each other with one connecting plate, and therefore the second posture of the bed base body can be firmly maintained.

[0017] The bed according to the fifth feature is a bed according to the fourth feature, in which the distance from the boundary line between the first bed base body and the second bed base body to the first screw hole portion and the distance from the boundary line between the first bed base body and the second bed base body to the second screw hole portion are set to different distances, and the distance from the center of the connecting plate to the first insertion hole portion and the distance from the center of the connecting plate to the second insertion hole portion are set to different distances.

[0018] According to the fifth feature of the invention, the positions of the first screw hole portion and the second screw hole portion are set asymmetrically, and the positions of the first insertion hole portion and the second insertion hole portion are set asymmetrically. Therefore, even if the connecting plate is placed in the opposite direction to the normal orientation, the screw hole portion is not exposed and the intermediate leg member cannot be attached, preventing incorrect assembly.

[0019] The bed according to the sixth feature is the bed according to the first feature, wherein the intermediate leg member has a pillar-like shape, and half the width of the intermediate leg member is set to be greater than the distance from the first screw hole portion to the boundary line between the first bed base body and the second bed base body.

[0020] According to the sixth feature of the invention, half the width of the pillar-shaped intermediate leg member is set to be greater than the distance from the first screw hole to the boundary between the first bed platform body and the second bed platform body, so that the intermediate leg member screwed into the first screw hole is screwed across the first bed platform body and the second bed platform body, thereby making the connection between the first bed platform body and the second bed platform body stronger and more stable.

[0021] A bed according to a seventh feature is the bed according to the first feature, wherein the intermediate leg member has a columnar shape and is formed so that the width of the intermediate leg member is larger than the width of the connection plate.

[0022] According to the seventh feature of the invention, the width of the intermediate leg member, which has a pillar-like shape, is formed to be larger than the width of the connecting plate, so that the upper surface of the intermediate leg member protrudes from the connecting plate and directly supports the bed base body from below, thereby enabling more stable and solid support of the bed base body.

[0023] The bed according to the eighth feature is the bed according to the first feature, wherein a positioning recess for positioning the connection plate is formed on the underside of the bed base body, and the first screw hole portion is formed in the positioning recess.

[0024] According to the eighth feature of the invention, a positioning recess for positioning the connecting plate is formed on the underside of the bed base body, and a first screw hole is formed in the positioning recess, so that simply fitting the connecting plate into the positioning recess aligns the first insertion hole of the connecting plate with the first screw hole of the bed base body, allowing the intermediate leg member to be screwed in without any hesitation.

[0025] A bed according to a ninth feature is a bed according to the eighth feature, wherein the positioning recess has a half-split shape that has the same planar shape as the connecting plate in the second position, so that in the second position, the positioning recess in the first bed base body and the positioning recess in the second bed base body can cooperate to position the connecting plate.

[0026] According to the invention relating to the ninth feature, the positioning recess has a half-split shape in the second position that has the same planar shape as the connecting plate so that the positioning recess in the first bed base body and the positioning recess in the second bed base body can work together to position the connecting plate in the second position.Therefore, when the first bed base body and the second bed base body are in the second position, there is no chance of placing the connecting plate in the wrong position. [Effects of the Invention]

[0027] According to the present invention, it is possible to provide a bed that can be easily assembled and packed compactly. [Brief explanation of the drawings]

[0029] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are merely examples and are not intended to limit the scope of the present invention.

[0030] The overall configuration of a bed 1 according to this embodiment will be described with reference to Figures 1 to 5. In this embodiment, the longitudinal direction refers to the direction from the head side to the foot side of the bed 1, and the width direction refers to the direction perpendicular to the longitudinal direction.

[0031] FIG. 1 is a perspective view showing the overall configuration of a bed 1 according to the present invention, with FIG. 1(a) showing a perspective view from above and FIG. 1(b) showing a perspective view from below. FIG. 3 is a schematic diagram of a bed platform main body 10 according to the present invention, with FIG. 3(a) showing a perspective view in a first position and FIG. 3(b) showing a perspective view in a second position. FIG. 4 is a partially enlarged view of the bed platform main body 10 according to the present invention, with FIG. 4(a) showing a partially enlarged view of the boundary line of the bed platform main body 10 at one widthwise end and FIG. 4(b) showing a partially enlarged view of the boundary line of the bed platform main body 10 at the other widthwise end. FIG. 5 is a schematic diagram of the components constituting the bed 1 according to the present invention, with FIG. 5(a) showing a perspective view of a connecting plate 20, FIG. 5(b) showing a plan view of the connecting plate 20, FIG. 5(c) showing a perspective view of a fixing bolt 30, and FIG. 5(d) showing a perspective view of leg members 40 and 50.

[0032] As shown in Fig. 1, the bed 1 according to the present invention comprises a first bed base body 10A and a second bed base body 10B, each of which has a rectangular shape in a plan view. The ends of the first bed base body 10A and the second bed base body 10B are rotatably connected to each other using hinge members 15 shown in Fig. 2, and the bed base body 10 can be switched between a first position in which the first bed base body 10A and the second bed base body 10B are overlapped, and a second position in which they are arranged side by side. The bed 1 also comprises a connection plate 20 that straddles the first bed base body 10A and the second bed base body 10B in the second position and connects them, and a fixing bolt 30 that fixes the connection plate 20 to the first bed base body 10A and the second bed base body 10B. The bed base body 10 is provided with a plurality of front and rear leg members 50 that can be attached and detached to both longitudinal ends of the underside of the bed base body 10 and serve as support legs for the installation surface, and an intermediate leg member 40 that can be attached and detached between the front and rear leg members 50 in the longitudinal direction of the underside of the bed base body 10 and has a fixing screw portion 41 for screwing onto the bed base body 10.

[0033] As shown in Figure 3(a), the first bed base body 10A and the second bed base body material 10B each include frame portions 11A, 11B assembled to form a rectangular peripheral portion in a plan view, and slats 12A, 12B arranged inside the frame portions 11A, 11B assembled to form a rectangular peripheral portion in a plan view, and which serve as a support surface for supporting a mattress.

[0034] As shown in Fig. 4(a), a positioning recess 13A for positioning the connecting plate 20 (described later) is formed in the frame 11A of the first bed body 10A at a position adjacent to the second bed body 10B. Similarly, a positioning recess 13B for positioning the connecting plate 20 is formed in the frame 11B of the second bed body 10B at a position adjacent to the first bed body 10A. As shown in Fig. 3(a) and Figs. 4(a)-(b), the positioning recesses 13A and 13B are formed one on each side in the width direction and one on the other side.

[0035] The positioning recesses 13A, 13B have a split half shape that has the same planar shape as the connecting plate 20 in the second position so that the positioning recess 13A in the first bed base body 10A and the positioning recess 13B in the second bed base body 10B can cooperate to position the connecting plate 20. In this embodiment, the two semi-elliptical positioning recesses 13A, 13B have a split elliptical shape so that they combine with each other to form a single elliptical shape.

[0036] 4(a) and 4(b), the positioning recesses 13A and 13B are formed with first screw holes 14a into which the fixing screw portions 42 of the first intermediate leg member 40A and the second intermediate leg member 40B can be screwed. Also, the positioning recesses 13A and 13B are formed with second screw holes 14b into which the bolt portion 32 of the fixing bolt 30 can be screwed.

[0037] 4(a)-4(b), the positioning recess 13A on the first widthwise side of the first bed body 10A is formed with a second screw hole 14b, and the positioning recess 13A on the other widthwise end of the first bed body 10A is formed with a first screw hole 14a. Meanwhile, the positioning recess 13B on the first widthwise side of the second bed body 10B is formed with a first screw hole 14a, and the positioning recess 13B on the other widthwise end of the second bed body 10B is formed with a second screw hole 14b. In other words, the pair of intermediate leg members 40A, 40B is such that the first intermediate leg member 40A is attached to the other widthwise end of the first bed body 10A, and the second intermediate leg member 40B is attached to one widthwise end of the second bed body 10B.

[0038] 4(a) and 4(b), in one pair of positioning recesses 13A, 13B, the distance X from the boundary line between the first bed base body 10A and the second bed base body 10B to the first screw hole 14a and the distance Y from the boundary line to the second screw hole 14b are set to different distances. In this embodiment, the distance X from the boundary line to the first screw hole 14a is set to be smaller than the distance Y from the boundary line to the second screw hole 14b. In other words, the intermediate leg member 40 is attached closer to the boundary line than the fixing bolt 30.

[0039] As shown in FIGS. 4(a) and 4(b), the diameter of the first screw hole portion 14a is set to be larger than the diameter of the second screw hole portion 14b.

[0040] The first bed platform body 10A and the second bed platform body 10B, which are rectangular in plan view, are configured by connecting opposing ends with hinge members shown in Figure 2 and arranging them side by side in the longitudinal direction so that the ends can rotate relative to each other. The first bed platform body 10A and the second bed platform body 10B can be stored in a stacked state as shown in Figure 2(b) by rotating one member relative to the other member using a connecting plate 20. In this embodiment, the first bed platform body 10A and the second bed platform body 10B can be stacked so that the surfaces opposite the surface on which the mattress is placed, i.e., the undersides, meet.

[0041] 5(a)-(b), the connection plate 20 is a member for connecting the first bed base body 10A and the second bed base body 10B, arranged so as to straddle the first bed base body 10A and the second bed base body 10B, and in this embodiment is formed from a flat metal plate having an elliptical shape in a plan view. The connection plate 20 is formed as an elliptical plate in a plan view so that when the first bed base body 10A and the second bed base body 10B are unfolded and assume the second position, the connection plate 20 fits into the positioning recesses 13A, 13B, which are each formed as half ellipses and combined to form an elliptical shape.

[0042] Each connecting plate 20 is formed with a first insertion hole 21 through which the fixing screw portion 42 of the first intermediate leg member 40A or the second intermediate leg member 40B can be inserted, and a second insertion hole 22 through which the bolt portion 32 of the fixing bolt 30 is inserted. The positions at which the first insertion hole 21 and the second insertion hole 22 are provided are asymmetrical with respect to the center of the connecting plate 20, and the first insertion hole 21 and the second insertion hole 22 have different diameters. In other words, just as the distance X from the boundary line between the first bed base body 10A and the second bed base body 10B to the first screw hole 14a on the underside of the bed base body 10 is set to be different from the distance Y from the boundary line to the second screw hole 14b, the distance S from the center position of the connecting plate 20 to the first insertion hole 21 is set to be smaller than the distance T from the center position to the second insertion hole 22. The distance X from the boundary between the first bed base body 10A and the second bed base body 10B to the first screw hole 14a is set to be approximately the same as the distance S from the center of the connecting plate 20 to the first insertion hole 21. Similarly, the distance Y from the boundary between the first bed base body 10A and the second bed base body 10B to the second screw hole 14b is set to be approximately the same as the distance T from the center of the connecting plate 20 to the second insertion hole 22.

[0043] The diameter of the first insertion hole portion 21 is set to be larger than the diameter of the second insertion hole portion 22.

[0044] The thickness of the connecting plate 20 is set so that when the connecting plate 20 is fitted into the positioning recesses 13A, 13B, the surface of the connecting plate 20 is approximately flush with the surfaces of the first bed base body 10A and the second bed base body 10B, and no steps are created.

[0045] As shown in Figure 5(c), the fixing bolt 30 is a member that is screwed into the second screw hole portion 14b of the first bed base body 10A and the second bed base body 10B to fix the connection plate 20 to the first bed base body 10A and the second bed base body 10B, and is equipped with a knob portion 31 that the user can grip for screwing, and a rod-shaped bolt portion 32 that extends from the knob portion 31 and has a male thread formed so that it can be screwed into the second screw hole portion 14b.

[0046] As shown in Figure 5(d), the first intermediate leg member 40A and the second intermediate leg member 40B that constitute the intermediate leg member 40 are members that support the first bed base body 10A and the second bed base body 10B on the floor, and are equipped with a cylindrical leg body 41 that is placed on the installation surface, and a rod-shaped fixing screw portion 42 that extends longitudinally from the end face of the leg body 41 and has a male thread so that it can be screwed into the first screw hole portion 14a formed on the underside of the first bed base body 10A and the second bed base body 10B.

[0047] The diameter of the cylindrical leg body 41 is set larger than the width, i.e., the short diameter, of the connecting fitting 20 so that the leg body 41 protrudes from the connecting fitting 20 when the fixing screw portions 42 of the first intermediate leg member 40A and the second intermediate leg member 40B are screwed into the first threaded hole portion 14a.

[0048] In addition, the relationship between the distance X from the boundary line between the first bed base body 10A and the second bed base body 10B to the first screw hole portion 14a and the diameter of the leg base body 41 is set so that the leg base body 41 straddles the boundary between the first bed base body 10A and the second bed base body 10B when the fixing screw portion 42 is screwed into the first screw hole portion 14a.

[0049] That is, the first intermediate leg member 40A is screwed into a first screw hole 14a formed in the underside of the first bed base body 10A, and the relationship between the distance X from the boundary between the first bed base body 10A and the second bed base body 10B to the first screw hole 14a and the diameter of the leg body 41 is set so that the relationship straddles the boundary between the first bed base body 10A and the second bed base body 10B. Similarly, the second intermediate leg member 40B is screwed into a first screw hole 14a formed in the underside of the second bed base body 10B, and the relationship between the distance X from the boundary between the first bed base body 10A and the second bed base body 10B to the first screw hole 14a and the diameter of the leg body 41 is set so that the relationship straddles the boundary between the first bed base body 10A and the second bed base body 10B. In this embodiment, the radius of the columnar leg body 41 is set to be larger than the distance X from the boundary line between the first bed base body 10A and the second bed base body 10B to the first screw hole 14a.

[0050] The front and rear leg members 50 include a first front and rear leg member 50A that is fixed to the first bed base body 10A and serves as a leg of the first bed base body 10A, and a second front and rear leg member 50B that is fixed to the second bed base body 10B and serves as a leg of the second bed base body 10B. The first front and rear leg member 50A and the second front and rear leg member 50B are attached, one at one end and one at the other end in the width direction, respectively, and as front and rear leg members 50, one is attached to each of the four corners of the bed base body 10. Each front and rear leg member 50 includes a cylindrical leg body 51 that is placed on the installation surface, and a rod-shaped fixing screw portion 52 that extends longitudinally from the end face of the leg body 51 and has a male thread formed thereon so as to be able to screw into threaded holes (not shown) formed on the undersides of the first bed base body 10A and the second bed base body 10B.

[0051] [Method of assembling bed 1 using this invention] Next, the procedure for assembling the bed 1 according to the present invention will be described with reference to Figures 3, 6, and 7. Figure 6 is a schematic diagram showing the procedure for assembling the bed 1 according to the present invention, where Figure 6(a) is a perspective view, Figure 6(b) is a partially enlarged view of one end in the width direction, and Figure 6(c) is a partially enlarged view of the other end in the width direction. Figure 7 is a partially enlarged view of the vicinity of the intermediate leg member 40 on one end in the width direction.

[0052] In the packaged state, the first bed base body 10A and the second bed base body 10B, the connecting plate 20, the fixing bolt 30, the first intermediate leg member 40A and the second intermediate leg member 40B, and the first front and rear leg member 50A and the second front and rear leg member 50B are packaged individually. However, the first bed base body 10A and the second bed base body 10B are connected to each other by the hinge member 15 shown in Fig. 2. Also, as shown in Fig. 3(b), the first bed base body 10A and the second bed base body 10B are packaged in a first position in which they are folded around the hinge member 15 and their bottom surfaces are overlapped.

[0053] When assembling the bed 1 packed in this state, the user first unfolds the folded first bed base body 10A and second bed base body 10B to assume the second position.

[0054] Next, as shown in Fig. 6(a), the connection plate 20 is fitted into the positioning recesses 13A and 13B formed on the undersides of the first bed base body 10A and the second bed base body 10B. At this time, the fitting direction is set so that the first insertion hole 21 formed in the connection plate 20 matches the first screw hole 14a formed in the positioning recesses 13A and 13B, and the second insertion hole 22 formed in the connection plate 20 matches the second screw hole 14b formed in the positioning recesses 13A and 13B. In other words, when the first bed base body 10A and the second bed base body 10B are unfolded and placed in the second position, the first screw hole portion 14a and the second screw hole portion 14b are not positioned symmetrically with respect to the boundary line, so if the connecting plate 20 is fitted in the positioning recesses 13A and 13B in reverse, the position of the first insertion hole portion 21 formed in the connecting plate 20 will not match the position of the first screw hole portion 14a formed in the positioning recesses 13A and 13B, and the first screw hole portion 14a will not be exposed from the first insertion hole portion 21, so the fixing screw portions 42 of the first intermediate leg member 40A and the second intermediate leg member 40B cannot be screwed together. Similarly, if the connecting plate 20 is fitted in the reverse direction, the position of the second insertion hole portion 22 formed in the connecting plate 20 will not match the position of the second screw hole portion 14b formed in the positioning recesses 13A, 13B, and the second screw hole portion 14b will not be exposed from the second insertion hole portion 22, so the bolt portion 32 of the fixing bolt 30 cannot be screwed in.

[0055] Once the connecting plate 20 has been fitted in the correct orientation, the fixing screw portions 42 of the first intermediate leg member 40A and the second intermediate leg member 40B are then inserted into the first insertion hole 21 and screwed into the first screw hole 14a. Furthermore, the bolt portion 32 of the fixing bolt 30 is inserted into the second insertion hole 22 and screwed into the second screw hole 14b. As a result, the bed base main body 10 can be fixed in the first position by the connecting plate 20, fixing bolt 30, and intermediate leg member 40, as shown in an example of one widthwise end in Figure 7.

[0056] Furthermore, the fixing screw portions 52 of the first front and rear leg member 50A and the second front and rear leg member 50B are screwed into other screw holes formed at the front and rear ends of the bed base body.

[0057] The order in which the first intermediate leg member 40A, the second intermediate leg member 40B and the fixing bolts 30 are screwed together is not particularly important.

[0058] In this way, the bed 1 can be easily assembled by simply unfolding the folded first bed base body 10A and second bed base body 10B to the second position, fitting the connecting plate 20 into the positioning recesses 13A and 13B, and then screwing together the fixing bolts 30, the intermediate leg members 40A and 40B, and the front and rear leg members 50A and 50B.

[0059] Even if the connecting plate 20 is attached in the reverse direction, the positions of the insertion hole of the connecting plate 20 and the screw-in hole of the first base member 10A and the second base member 10B will not match, and the intermediate leg member 40 and the fixing bolt 30 cannot be attached, so there is no risk of incorrect attachment.

[0060] When in the second position, a total of four first front and rear leg members 50A and second front and rear leg members 50B are attached in two locations on each of the longitudinal ends of the unfolded first bed base body 10A and second bed base body 10B, and further, one first intermediate leg member 40A and one second intermediate leg member 40B are attached near the boundary line between the first base member 10A and second base member 10B. As the first base member 10A and second leg member 10B are supported by a total of six leg members, there is sufficient space below the first bed base body 10A and second bed base body 10B to place storage boxes such as clothing cases.

[0061] The bed of the present invention includes a first bed base body 10A and a second bed base body 10B, each rectangular in plan view, whose ends are rotatably connected to each other using hinge members 15 and switchable between a first position where they are stacked and a second position where they are arranged side by side. Therefore, the bed can be packed compactly by stacking the first bed base body 10A and the second bed base body 10B in the first position. When assembled, the first bed base body 10A and the second bed base body 10B are placed in the second position, and then the connecting plate 20 is fixed to the bed base body 10A across the first bed base body 10A and the second bed base body 10B, thereby maintaining the second position. At this time, the flat surface of the connecting plate 20 supports the weight of the first bed base body 10A and the second bed base body 10B, allowing the bed base body 10A to be stably fixed in the second position. Furthermore, by inserting the fixing screw portion 42 of the intermediate leg member 40 into the first insertion hole portion 21 of the connecting plate 20 and screwing it into the first screw hole portion 14a, the connecting plate 20 is fixed in close contact with the underside of the bed base main body 10, so that by simply inserting the fixing screw portion 42 into the first insertion hole portion 21 and turning the intermediate leg member 40 by hand to screw it into the first screw hole portion 14a, it is possible to simultaneously fix the intermediate leg member 40 itself and stably maintain the second posture of the bed base main body 10.

[0062] Furthermore, by providing the intermediate leg members 40 in two locations, the bed base body 10 is supported by a total of six leg members, including the two sets of front and rear leg members 50 provided at the front and rear ends of the bed base body 10. This makes it possible to ensure space below the bed base body 10 for storing clothing cases and the like. Furthermore, by providing one of the intermediate leg members 40 provided in two locations on the first bed base body 10A and the other on the second bed base body 10B, the bed base body can be supported in a well-balanced manner.

[0063] Furthermore, by inserting the fixing bolt 30 into the second insertion hole portion 22 of the connection plate 20 and screwing it into the second screw hole portion 14b, the connection plate 20 can be pressed against the bed base main body 10 not only by fastening it with the intermediate leg member 40 but also by the fixing bolt 30, so that the connection plate 20 can be more firmly fixed to the bed base main body 10 and a more stable second posture can be maintained.

[0064] Furthermore, by screwing the fixing screw portion 42 of the intermediate leg member 40 into the first screw hole portion 14a formed in one of the first bed base body 10A or the second bed base body 10B, and screwing the bolt portion 32 of the fixing bolt 30 into the second screw hole portion 14b formed in the other of the first bed base body 10A or the second bed base body 10B, it is possible to connect the two bed base bodies 10 across each other with one connecting plate 20, and therefore the second posture of the bed base body 10 can be firmly maintained.

[0065] Furthermore, since the positions of the first screw hole portion 14a and the second screw hole portion 14b are set asymmetrically, and the positions of the first insertion hole portion 21 and the second insertion hole portion 22 are set asymmetrically, even if an attempt is made to position the connection plate 20 in the opposite direction to the normal orientation, the screw hole portions are not exposed and the intermediate leg member 40 cannot be attached, preventing incorrect assembly.

[0066] Furthermore, because half the width of the pillar-shaped intermediate leg member 40 is set to be greater than the distance X from the first screw hole 14a to the boundary line between the first bed base body 10A and the second bed base body 10B, the intermediate leg member 40 screwed into the first screw hole 14a is screwed across the first bed base body 10A and the second bed base body 10B, thereby making the connection between the first bed base body 10A and the second bed base body 10B stronger and more stable.

[0067] Furthermore, since the width of the intermediate leg member 40, which has a columnar shape, is formed to be larger than the width of the connecting plate 20, the upper surface of the intermediate leg member 40 protrudes from the connecting plate 20 and directly supports the bed base body 10 from below, thereby enabling the bed base body to be supported more stably and firmly.

[0068] Furthermore, positioning recesses 13A and 13B for positioning the connecting plate 20 are formed on the underside of the bed base body 10, and first screw holes 14a are formed in the positioning recesses 13A and 13B, so that simply fitting the connecting plate 20 into the positioning recesses 13A and 13B makes it possible to align the first insertion holes 21 of the connecting plate 20 with the first screw holes 14a of the bed base body 10. This makes it possible to screw in the intermediate leg members 40 without any hesitation.

[0069] Furthermore, the positioning recesses 13A, 13B have a half-split shape that has a planar shape similar to that of the connecting plate 20 in the second position, so that in the second position, the positioning recess 13A in the first bed base body 10A and the positioning recess 13B in the second bed base body 10B can work together to position the connecting plate 20.Therefore, when the first bed base body 10A and the second bed base body 10B are in the second position, there is no chance of placing the connecting plate 20 in the wrong position.
