[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bed apparatus that can use the internal space of a base as a container.
[0002]
[Prior art]
The bed apparatus has a box-shaped base body in which a headboard is erected on one end in the longitudinal direction, and a mattress body is provided on the upper surface of the base body. The mattress body has a floor board, and a cushion body is integrally provided with the floor board on the upper surface of the floor board. In some bed apparatuses having such a configuration, the internal space of the base body can be used as a container.
[0003]
In order to use the internal space of the base as a storage case, one end of the floor board on the headboard side is rotatably connected to the base, and the top of the base is opened by rotating the floor board up. To be able to.
[0004]
When a cushion body is provided on the upper surface of the floor board and its one end face is close to the inner surface of the headboard (the side surface on the mattress body side), the mattress will vary depending on its thickness when the floor board is rotated up with one end as a fulcrum. One end surface of the body hits the inner surface of the headboard, and the rotation is prevented from rising.
[0005]
If one end surface of the mattress body is separated from the inner surface of the headboard by a predetermined distance, it is possible to prevent the one end surface from hitting the inner surface of the headboard when the mattress body is rotated and raised. However, if there is a gap between one end surface of the mattress body and the inner surface of the headboard, not only the usability is deteriorated, but the appearance may be deteriorated.
[0006]
Therefore, conventionally, the floor board is rotatably attached to the base body by a link. That is, one end of a pair of links is pivotally attached to inner surfaces on both sides of one longitudinal end of the base, and the other ends of these links are pivotally attached to both widthwise ends of the longitudinal end of the floorboard. In addition, a gas spring is provided between the base and the floor plate so as to extend when the floor plate is rotated in the upward direction so that the floor plate can be rotated and raised with a light force, and the state is raised. It can be held with.
[0007]
When the mattress body is rotated in the upward direction, the mattress body is moved in a direction in which one end is separated from the headboard by the action of the link, so that the mattress body has a predetermined thickness. The mattress body can be rotated in the ascending direction without the upper portion in the thickness direction of the one end surface contacting the inner surface of the headboard.
[0008]
In that case, a roller is provided at one end of the mattress body, and the roller is engaged with an engagement groove formed in the base so as to be able to roll, thereby smoothly moving the one end of the floor board in a direction away from the headboard. I am doing so.
[0009]
[Problems to be solved by the invention]
However, according to such a configuration, in order to attach the mattress body to the base body, a link and a roller for guiding the mattress body so as to be movable along the longitudinal direction of the base body are required. Further, in order to guide the roller, the base body An engagement groove must be formed on the surface.
[0010]
Therefore, in order to make the mattress body turnable so that one end face thereof does not hit the headboard, the number of parts increases, resulting in a complicated structure and an increase in cost.
[0011]
Further, when one end of the mattress body is attached to the base by a link and the one end of the mattress body is moved with the rotation, the one end of the mattress body is not firmly connected to the base and is rotated together with the link. Since it is easy to move in the lateral direction crossing the moving direction, the support state of the mattress body that is rotated and raised may become unstable.
[0012]
According to the present invention, a mattress body having a predetermined thickness with a small number of parts can be reliably rotated and raised without hitting the headboard, and when the mattress body is rotated and raised, it is difficult to swing laterally. It is in providing the bed apparatus which was made.
[0013]
[Means for Solving the Problems]

[0017]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0018]
FIG. 1 shows a bed apparatus according to an embodiment of the present invention, and this bed apparatus includes a base 1. The base body 1 is formed in a rectangular box shape whose upper surface is opened, and an inner plate 3 is provided on the inner surface side of the pair of side plates 2 at a predetermined distance from the side plate 2 over the entire length in the longitudinal direction. Further, a head board 4 is erected on one end of the base 1 in the longitudinal direction.
[0019]
A mattress body 5 is provided on the upper surface of the substrate 1. The mattress body 5 includes a bottom 6 having a size for closing the opening on the upper surface of the base 1 and a mattress 7 placed on the upper surface of the bottom 6. The bottom 6 includes a wooden frame 8 and a spring unit 9 fixed to the upper surface of the wooden frame 8.
[0020]
On the lower surface of the wooden frame 8, as shown in FIG. 2, a total of four vertical bars 11 are provided over the entire length in the longitudinal direction at both ends in the width direction and in the middle. The vertical bars 11 at both ends in the width direction are in contact with the upper end surface of the side plate 2 of the base 1.
[0021]
On the inner surface of the headboard 4 facing the base body 1 side, a pair of support members 12 are spaced apart at a predetermined interval in the width direction at a position corresponding to a midway portion in the height direction of one end surface of the upper mattress 7 of the mattress body 5. And fixed. Both ends of a horizontal bar 13 made of a pipe material are supported by the pair of supporters 12 so as to be rotatable and immovable in the axial direction. One end of a pair of connecting rods 14 formed by bending the pipe material in a substantially L shape is fixed to the horizontal rod 13.
[0022]
The other end portions of the pair of connecting rods 14 are located on the lower surface side of one end portion of the mattress body 5, and the lower surface of the wooden frame 8 of the mattress body 5 by a U-shaped connector 15 engaged with the one end portion. Are connected and fixed to a pair of vertical bars 11 provided in the middle in the width direction.
[0023]
Further, rectangular fixing plates 16 are fixed to the lower ends of the vertical portions in FIG. These fixing plates 6 are fixed to one end surface of the wooden frame 8 of the bottom 6 by screws 17 as shown in FIG.
[0024]
Accordingly, the mattress body 5 can be rotated by the connecting rod 14 in the upward direction indicated by the chain line from the lying state indicated by the solid line in FIG. That is, the horizontal bar 13 and the connecting bar 14 constitute connecting means 18 that connects the mattress body 5 to the headboard 4 of the base 1 so as to be able to undulate (turnable).
[0025]
As shown in FIG. 2, gas springs 21 are provided in a pair of space portions defined by the side plate 2 and the inner plate 3 of the base 1. One end of the gas spring 21 is pivotally attached to a lower connector 22 provided at a lower end portion of the side plate 2 in the longitudinal direction, and the other end of the gas spring 21 is disposed in the longitudinal direction of the longitudinal beam 11 at both ends in the width direction of the base frame 8. It is pivotally attached to the upper connector 23 provided on the inner surface side of the part.
[0026]
The pair of gas springs 21 extend by rotating the mattress body 5 in the direction in which the other end rises with the one end connected to the connecting rod 14 as a fulcrum. That is, since the restoring force of the gas spring 21 acts on the mattress body 5 by rotating the mattress body 5 in the upward direction, the mattress body 5 can be rotated and raised with a light force by the restoring force. It can be held in a raised state so as not to fall down.
[0027]
If the mattress body 5 is pressed in the lying direction against the restoring force of the gas spring 21, the mattress body 5 can be gently lowered by the restoring force of the gas spring 21.
[0028]
In the bed apparatus configured as described above, when the mattress body 5 is rotated in the ascending direction as indicated by the chain line from the state where the mattress body 5 is lying in a substantially horizontal position as indicated by the solid line in FIG. It rotates with 13 as a fulcrum. The horizontal rail 13 is provided at a position corresponding to the upper portion in the thickness direction of the mattress body 5 that has fallen almost horizontally on the base body 1. That is, the horizontal rail 13 is provided at a height corresponding to the end surface of the upper mattress 7 provided on the bottom 6.
[0029]
Therefore, when the mattress body 5 is rotated in the direction in which the other end rises with the horizontal rail 13 as a fulcrum, the one end surface facing the inner surface of the headboard 4 has the upper part in the height direction as the fulcrum and the lower part is the headboard 4. Therefore, even if the mattress body 5 is rotated in the upward direction, one end of the mattress body 5 does not hit the inner surface of the head board 4 and cannot be rotated.
[0030]
That is, even when the mattress body 5 is lying down almost horizontally and its one end surface is close to the inner surface of the headboard 4, the other end portion is raised without the one end surface hitting the inner surface of the headboard 4. Can be rotated in the direction.
[0031]
One end of the mattress body 5 is fixed to the connecting rod 14 of the connecting means 18. Therefore, the mattress body 5 is firmly connected and fixed without rattling to the connecting rod 14.
[0032]
One end of the connecting rod 14 is fixed to the horizontal rod 13, and both ends of the horizontal rod 13 are rotatably supported by the pair of support tools 12. Therefore, the connecting rod 14 whose one end is fixed to the horizontal rod 13 is also firmly connected to the headboard 4 via the horizontal rod 13.
[0033]
Therefore, the mattress body 5 is supported in a stable state without swinging in a direction crossing the rotation direction in a state where the mattress body 5 is rotated and raised.
[0034]
That is, according to the bed apparatus having the above-described configuration, even when one end surface of the mattress body 5 is installed close to the inner surface of the head board 4, when the mattress body 5 is rotated in the upward direction, the mattress body 5 is moved to the head. Even if it is not moved away from the inner surface of the board 4, it is possible to prevent one end surface of the board 4 from hitting the inner surface of the head board 4.
[0035]
Therefore, compared with the case of the conventional structure in which the mattress body 5 is moved, the configuration can be simplified and the support state can be stabilized when the mattress body 5 is raised.
[0036]
5 and 6 show a second embodiment of the present invention showing a modification of the connecting means. The connecting means 18 </ b> A of the second embodiment is formed by a pair of connecting members 25. Further, as shown in FIG. 6, the mattress body 5A has a configuration in which a cushion body 27 is integrally provided on a substrate 26, and the bottom 6 and the upper mattress 7 are connected as in the first embodiment. It is different from the configuration that it has.
[0037]
The connecting member 25 is formed by bending a plate material into a substantially L shape, and one end of the connecting member 25 is at a position corresponding to the upper portion of the mattress body 5A in the height direction, and the support shaft 28 is attached to the end surface of the headboard 4 in the width direction. It is attached to be rotatable.
[0038]
One end portion of the connecting member 25 is provided along the side surface of one end portion of the mattress body 5A, and the other end portion is joined to the lower surface of the substrate 26 at one end portion of the mattress body 5A and is connected and fixed by screws 29.
[0039]
In addition, since the structure of another part is the same as 1st Embodiment, it attaches | subjects the same symbol to the same part, and abbreviate | omits description.
[0040]
Even in the bed apparatus having such a configuration, the mattress body 5A can be rotated in the upward direction with one end portion of the connecting member 25, that is, the upper portion in the thickness direction of the mattress body 5A as a fulcrum.
[0041]
Therefore, even if one end surface of the mattress body 5A is placed close to the inner surface of the head board 4, the mattress body 5A can be rotated in the upward direction without the one end surface contacting the inner surface of the head board 4.
[0042]
In addition, the mattress body 5A is configured to be pivotally connected to the headboard 4 by the pair of connecting members 25, and is not configured to move along the longitudinal direction of the base body 1 by being rotated and raised as in the prior art. It can be supported in a stable state without swinging in the lateral direction in the state of being rotated and raised.
[0043]
The first embodiment and the second embodiment are different in the structure of the mattress body. However, the mattress body of any structure may be used, and the mattress is mounted on the floor board. The present invention can be applied to any mattress body having a predetermined thickness.
[0044]
7 and 8 show a third embodiment of the present invention. This embodiment is a modification of the mattress body 5B. That is, the mattress body 5 </ b> B is formed by placing the mattress 32 on the frame 31. The frame 31 has a frame member 33 in which three sides excluding one side in the longitudinal direction are rectangular pipes, and one side located on the headboard 4 side in the longitudinal direction is formed into a rectangular frame shape by an angle member; The frame member 33 is formed by a wire 34 stretched vertically and horizontally.
[0045]
The connecting means 18 for connecting the frame 31 to the headboard 4 is substantially the same as that of the first embodiment, but one end of a pair of linear first connecting rods 14a is fixed to the horizontal rod 13, and this A midway portion of the second connecting rod 14b having a U-shaped planar shape is connected and fixed to the other end of the first connecting rod 14a. Both sides of the second connecting rod 14b are introduced into the frame member 33 from the lower surface side of one side formed by the angle member of the frame member 33, and are bonded and fixed to the inner surfaces of the both sides.
[0046]
The other parts are almost the same as those of the first embodiment, and the same parts are denoted by the same reference numerals and the description thereof is omitted.
[0047]
Also in the bed apparatus having such a configuration, the rotation fulcrum of the mattress body 5B is provided at a position corresponding to the upper part in the thickness direction of the mattress body 5B, as in the first and second embodiments. Therefore, even if one end surface of the mattress body 5B is brought close to the inner surface of the headboard 4, the mattress body 5B can be rotated and raised without hitting the headboard 4.
[0048]
【The invention's effect】
As described above, according to the present invention, the mattress body is rotatably connected to the headboard at a position corresponding to the upper portion in the thickness direction by the connecting means.
[0049]
Therefore, when the mattress body is rotated in a direction in which the other end side is raised with the one end side connected by the connecting means as a fulcrum, the one end surface facing the inner surface of the headboard is in a direction in which the lower end portion is separated from the inner surface of the headboard. Therefore, even if one end surface of the mattress body is placed close to the inner surface of the headboard, the mattress body can be rotated in the upward direction without the one end surface contacting the inner surface of the headboard.
[0050]
In addition, the mattress body only needs to be pivotally connected to the headboard, and it is not necessary to move the mattress body along the longitudinal direction of the base body as the mattress body is rotated and raised as in the prior art. Not only can the simplification be achieved, it is possible to improve the stability in the state of being rotated up.
