Both ends of a second leg member 21 formed by bending a pipe material into a substantially U-shape are rotatably connected to the pair of second mounting members 19 by a second support shaft 22. The second leg member 21 is rotatable between a lying state opposed to the lower surface of the second frame 3 shown by a chain line in FIGS. 1A and 3 and an upright state shown by a solid line. When it is turned at an angle slightly larger than 90 degrees in the upright direction, the end pivotally attached to the second support shaft 22 abuts on the closed side wall of the second fixture 19 and turns further. Is prevented from doing so. In this state, the second frame 3 is supported by the second leg member 21 at substantially the same height as the first frame 2 and in a substantially horizontal state.
[0023]
When the second frame 3 is substantially horizontal, both ends of the pipe material of the second frame 3 come into contact with both ends of the pipe material of the first frame 2 as shown in FIG. The rotation of the pair of connection pieces 5, 6 of the hinge mechanism 4 connected by the connection 7 is prevented. As a result, the second frame 3 is prevented from rotating further downward at one end, and is supported substantially horizontally by the first leg member 15 and the second leg member 21. You.

When the second frame 3 is folded so as to face the lower surface of the first frame 2, in this state, the engaging portion 33 of the handle member 31 is engaged with the second connecting piece 6 as shown in FIG. The hole 34 can be engaged. Thereby, the folded second frame 3 can be held non-rotatably with respect to the first frame 2. That is, the stopper mechanism 25 can hold the first frame 2 and the second frame 3 so as not to rotate in both the horizontally expanded state and the two-folded state. I have.
[0031]
As shown in FIGS. 2 and 4, receiving members 36 made of an angle material are provided on both inner surfaces of the first frame 2 and the second frame 3. A pair of receiving members 36 of each of the frames 2 and 3 are provided with floor members 37 each having a child-like shape at predetermined intervals in the longitudinal direction of the bed frame 1.
[0032]
The floor member 37 has a plurality of strip-shaped crosspiece members 38 that are installed along the width direction of each of the frames 2 and 3. As shown in FIG. 4, the crosspiece 38 has a two-layer structure in which a synthetic resin sheet 38b is adhered to the upper surface of a strip 38a, and the upper surface has a convex curved surface.
[0033]
Both ends of each crosspiece 38 are inserted into a box-shaped support member 39 with one side open. As shown in FIGS. 3 and 4, a band-shaped spring 41 is provided on the lower surface of the support member 39, and elastically supports the support member 39 on the receiving member 36.
[0034]
As shown in FIG. 3, a pair of adjacent support members 39 that are separated from each other at a predetermined interval are rotatably connected by connecting pieces 42. In this embodiment, as shown in FIG. 2, the first frame 2 and the second frame 3 are each provided with seven crosspieces 38.
[0035]
As shown in FIG. 3, the storage member 39 that stores and holds the ends of the rail members 38 positioned at both ends in the longitudinal direction of each of the frames 2 and 3 is attached to a mounting tool 43 provided on the receiving member 36 by a connecting pin 44. They are connected in a rotatable state. FIG. 3 shows only one end of the second frame 2, but the other end and both ends of the floor member 37 provided on the first frame 2 are similarly connected to the frames 2 and 3. . Thus, when the first and second frames 2 and 3 are raised, the cross member 38 of the floor member 37 does not come off from each of the frames 2 and 3.
[0036]
A mattress 45 is placed on the crosspiece 38 of the first and second frames 2 and 3. As shown in FIG. 6B, the mattress 45 includes a first portion 45a mounted on the first frame 2 and a second portion 45b mounted on the second frame 3. Are foldably and dividably connected by a connecting cloth 47 provided with a fastener 46 in the middle in the width direction.
[0037]
The first portion 45a and the second portion 45b of the mattress 45 are held on the first frame 2 and the second frame 3 of the bed frame 1 by bands (not shown) so as not to fall off, respectively. If the band is detached from the bed frame 1, it can be detached from the bed frame 1.
[0038]
In the bed apparatus having the above configuration, the first frame 2 and the second frame 3 are developed horizontally at the time of going to bed as shown in FIG. 1A, and the mattress 45 is placed on the upper surfaces of the frames 2 and 3. Then, the user can lie on the mattress 45.
[0039]
When the bed frame 1 is expanded horizontally, the pair of connecting pieces 5 and 6 of the hinge mechanism 4 that rotatably connects the first frame 2 and the second frame 3 cannot be rotated by the stopper mechanism 25. Is held. Therefore, the first frame 2 and the second frame 3 that have been deployed substantially horizontally are reliably held in the deployed state by the stopper mechanism 25, so that the bed apparatus can be used in a stable state.
[0040]
When the bed apparatus is stored when not in use, first, the bed frame 1 is erected such that the outer surface of the end member 8 on which the casters 13 are provided faces down as shown in FIG. At this time, it is easier to set up the bed frame 1 by operating the stopper of the caster 13 so that the caster 13 cannot travel. When the bed frame 1 is set up, the first and second leg members 15 and 21 are folded so as to lie down on the frames 2 and 3.
[0041]
Then, a band (not shown) holding the second portion 45b of the mattress 45 on the second frame 3 is removed, and the upper surface of the second portion 45b is held on the first frame 2 as shown in FIG. The first portion 45a is folded so as to contact the upper surface of the first portion 45a. Thereby, the first part 45a and the second part 45b of the mattress 45 folded in two are held on the end member 8 in an upright state.
[0042]
Then, as shown in FIG. 5C, the handle member 31 of the stopper mechanism 25 that has made the hinge mechanism 4 unrotatable is pulled against the urging force of the spring 29, and the engaging portion 33 at the tip is moved to the second position. Remove from the engagement hole 34 of the connecting piece 6. Thereby, the first connecting piece 5 and the second connecting piece 6 of the hinge mechanism 4 are in a rotatable state.
[0043]
In this state, the second frame 3 is folded in the direction in which the lower surface faces the lower surface of the first frame 2 as shown in FIG. When the second frame 3 is folded to a predetermined state, the engaging portion 33 at the distal end of the handle member 31 of the stopper mechanism 25 automatically engages with the engaging hole 34 of the second connecting piece 6. In this state, the second frame 3 is non-rotatably held.
[0044]
As described above, since the first frame 2 and the second frame 3 are foldably connected to each other by the hinge mechanism 4, the bed frame 1 has an end member when stored without using the bed device. The height dimension of the bed frame 1 can be reduced to about half by folding the second frame 3 so as to face the first frame 2 with the 8 facing down.
[0045]
Therefore, when the bed device is moved to the storage place by running the bed device by the casters 13 provided on the end member 8, the height of the bed device is reduced to about half. Can be. In addition, when moving to another floor by placing it on an elevator, the height dimension is reduced to about half, so even when the height of the elevator is low, the bed device can be easily placed and moved. Can be done.
[0046]
The first frame 2 and the second frame 3 of the folded bed frame 1 cannot be rotated by the stopper mechanism 25, that is, the folded state is securely held. Therefore, it is not difficult to move the second frame 3 when moving.
[0047]
When the stopper mechanism 25 folds the second frame 3, the engaging portion 33 of the handle member 31 automatically engages with the engaging hole 34 of the second connecting piece 6 by the restoring force of the spring 29. Therefore, the folded second frame 3 can be securely and non-rotatably held with respect to the first frame 2 without any special operation.
[0048]
As shown in FIG. 6B, the mattress 45 placed on the bed frame 1 is folded with the upper surface of the second portion 45b in contact with the upper surface of the first portion 45a, and the end member 8 is folded. Are placed side by side with the folded first and second frames 2, 3. Therefore, since the mattress 45 can be handled integrally with the bed frame 1, handling of the folded bed device becomes easy.
[0049]
In the above embodiment, the first leg member is provided so as to be able to undulate at the end of the first frame. However, the first leg member is undulated near the second connecting piece of the second frame. Even if it is possible to provide, there is no problem.
[0050]
The mattress is divided into a first part and a second part, and these two parts are connected so as to be able to be bent and separated. However, the mattress is not divided into two parts and one mattress is used. It may be a foldable configuration.
[0051]
Further, the end member is formed by forming the pipe material into a mountain shape, but the shape is not limited.Moreover, instead of bending the pipe material into a predetermined shape, a plate shape may be used. Any structure may be used as long as it can be connected to the bed frame and connected to it, and a caster can be provided on the other side.
[0052]
In addition, the stopper mechanism constituting the holding means rotates the pair of connecting pieces of the hinge mechanism both when the first frame and the second frame of the bed frame are horizontally expanded and when the bed frame is folded. Although the first frame and the second frame can be held in a non-rotatable manner, the pair of connecting pieces of the hinge mechanism are non-rotatably held by separate stopper mechanisms when the first frame and the second frame are horizontally expanded and when they are folded. You may make it. In this case, the stopper mechanism may not be provided on the hinge mechanism, but may be provided on the first frame or the second frame.
[0053]
Further, the holding means for holding the first and second frames in the horizontally expanded state and in the folded state in the folded state is not limited to the stopper mechanism having the above-described structure. When the frame is unfolded horizontally, the hinge mechanism is configured such that the pair of connecting pieces of the hinge mechanism does not rotate any more.When the frame is folded, the pair of opposing frames is undeployably connected by connecting pieces or a belt. In other words, any configuration may be used as long as the first and second frames can be held in the horizontally expanded state and in the folded state.
[0054]
【The invention's effect】
As described above, according to the present invention, when the bed frame is moved upright, the bed frame can be folded into two.
[0055]
Therefore, when the bed device is stored, it can be moved in a stable state, and when it is transported to another floor by an elevator or the like, it must be securely and easily put in and out of a narrow space such as an elevator. Can be.
