DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle bed (hereinafter, simply referred to as "bed").

[0002]

2. Description of the Related Art With the recent increase in outdoor life, various types of beds for installing in a vehicle interior have been provided. Normally, this kind of bed has a structure in which a steel pipe frame is attached to a flat bed body, for example, a lauan plywood with a skin attached thereto, to have a necessary rigidity, and is provided in a vehicle interior. A type that is used by hanging it near the roof of the cabin through a hanging bracket or a hanging belt,
Alternatively, there is provided a type which is used by being placed on a fully reclined sheet.

[0003]

However, the conventional bed has a problem that it is heavy because the bed body is mainly composed of Rawan plywood and the frame is made of steel pipe as described above. There was a problem that the handleability at the time of installation or removal was not good. In addition, it has been difficult to provide a bed at a stable cost because the rawan material fluctuates greatly due to changes in market conditions. An object of the present invention is to provide a vehicle bed that is light and easy to handle and that can be provided at a stable cost at all times.

[0004]

According to the present invention, there is provided a vehicle bed to be installed and used in a vehicle cabin, wherein the bed body surrounds a corrugated cardboard frame with a frame. A cushion material is placed on the skin and covered with a skin. According to this vehicle bed, since the bed body is made of cardboard,
The bed is lighter than a conventional Rawan plywood product, which reduces the weight of the bed and improves its handling. Corrugated cardboard has less market price fluctuations than Rawan plywood, and thus can provide the bed at a more stable cost.

[0005] The vehicle bed according to the second aspect is the first aspect.
The vehicle bed according to any one of the preceding claims, wherein a plurality of bed bodies are connected flush with each other using a connection member. According to this vehicle bed, since it can be disassembled into a plurality of bed bodies, it is convenient to carry and the handling at the time of assembly is improved.

According to a third aspect of the present invention, there is provided a vehicle bed.
The bed for a vehicle according to claim 1, wherein the cardboard of the bed body has a three-layer structure in which cardboard sheets are laminated on upper and lower surfaces of a core material, and the core material has a corrugated shape that is undulating in the surface direction of the bed body. The corrugated cardboard sheet is mainly composed of a core, and the corrugated cardboard sheet is characterized in that a corrugated central core that rises and falls in the thickness direction of the bed body is laminated on the core material via a liner. According to this vehicle bed,
Practically sufficient rigidity can be given to the bed body.
In particular, when a person lays on the bed, a bending force is applied to the bed body in the width direction rather than the longitudinal direction (the height direction of the person). The rigidity of the material and the corrugated cardboard sheet is exhibited most effectively.

[0007] Since the undulating direction of the core in the core material is the longitudinal direction or the width direction (hereinafter referred to as the surface direction) of the bed, the surface direction of the core is a direction orthogonal to the surface direction of the bed (ie, the vertical direction). Placed in Therefore, the weight of the person and the bending force in the width direction applied when the person lays down on the bed are applied as surface forces to the center, so that the core material is Demonstrate sufficient rigidity.

[0008]

FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIG. As shown in FIG. 1, the bed 1 of the present embodiment is used by connecting four bed bodies 2 to 2 flush. In the following description, the height direction of a person in a state where a person is lying on the bed 1 is referred to as a longitudinal direction L of the bed 1, a direction orthogonal to the longitudinal direction L is referred to as a width direction W of the bed 1, and a thickness direction. Is referred to as the thickness direction T of the bed 1. The four bed bodies 2-2 are arranged along the longitudinal direction L of the bed 1. However, each bed body 2 is short in the longitudinal direction L and long in the width direction W. A frame 3 is attached around each bed body 2, and a skin 4 is put on the frame 3 from above (FIG. 4 (c)). The connection structure between the bed bodies 2 and 2 will be described later.

The four bed bodies 2 to 2 have the same configuration. Each bed body 2 is mainly made of a flat corrugated cardboard.
And cardboard sheets 11, 11 laminated on both upper and lower surfaces thereof
In a three-layer structure. The core member 10 has a configuration in which a plurality of corrugated cores 10a to 10a are arranged in a direction in which the undulating direction of the corrugations is along the longitudinal direction L of the bed 1 (hereinafter, also referred to as "vertical direction"). have.

Each of the cores 10a is arranged in the width direction W of the bed 1.
And thus the plurality of cores 10a
The direction of continuous arrangement of 10 to 10 a coincides with the longitudinal direction L of the bed 1. A liner 1 is provided between the cores 10a to 10a.
0b is interposed. Each liner 10b has a core 1
The bed 1 is manufactured using a strip-shaped sheet material having the same width as 0a, and is arranged in such a direction that its width direction (plane direction) is aligned with the thickness direction T of the bed 1. Each liner 10b is bonded at each vertex of each corrugated shape of each core 10a. As described above, the cores 10a to 10a and the liners 10b to 10b are arranged vertically with their surface directions along the thickness direction T of the bed 1, so that the load in the thickness direction T is large. It is designed to exhibit rigidity.

Next, the two corrugated cardboard sheets 11, 11 are formed by laminating liners 11b, 11b on the upper and lower surfaces of a core 11a, respectively. They are arranged sideways so as to match the direction T. Further, the longitudinal direction LW of the wave of the core 11 a is along the width direction W of the bed 1. The longitudinal direction LW of the wave refers to the direction of the ridgeline of the vertex of the wave as shown in FIG.

Each of the liners 11b to 11b has a plate shape having substantially the same area as the bed body 2, and
1a is bonded to the top of each wave shape. Further, both corrugated cardboard sheets 11, 11 are adhered to the upper and lower surfaces of the core material 10 via the liner 11b. The surface of the corrugated cardboard sheet 11 on the upper surface side is treated with a resin coating or a resin impregnation or both in order to provide water resistance to take measures against moisture when the bed 1 is used.

A frame 3 is attached to the periphery of the bed body 2 configured as described above, as shown in FIG. The frame 3 is stretched between the vertical frames 3a, 3a along the longitudinal direction L of the bed 1, the horizontal frames 3b, 3b along the width direction W of the bed 1, and the horizontal frames 3b, 3b. The three reinforcing frames 3c to 3c with rivets 3d, respectively.
To 3d and are integrally assembled. Vertical frames 3a, 3a, horizontal frames 3b, 3b, reinforcing frames 3c to 3c
c are all made of aluminum as a material, and the bed 1 is also lightened.

A skin 4 is wrapped around the bed body 2 to which the frame 3 is attached. The outer skin 4 is manufactured by sewing the front side and the rear side, and a zipper 4b is attached to a side portion thereof.
It can be removed from. A cushion material (soft polyurethane foam) 4a is interposed between the outer skin 4 and the upper surface of the bed body 2 to ensure the cushioning property of the bed 1.

The bed 1 constructed as described above is assembled in, for example, a manner shown in FIG. FIG. 5B shows a state in which the bed 1 of the present embodiment is installed in a vehicle having three rows of seats 5 to 7. Here, as shown in FIG. 3, the bed bodies 2, 2 are connected flush with each other using connection members 12 to 12 each having a pin portion 12b, 12b on both surfaces of a flange portion 12a. That is, by inserting the pin portions 12b of the respective connecting members 12 into the square pipe openings 3e of the frame 3, the adjacent bed bodies 2 are connected flush. FIG. 5A shows a state in which the four bed bodies 2-2 are connected flush with each other via the connection members 12-12.

On the other hand, as shown in FIG. 5B, a leg 8 for receiving the bed 1 is provided behind the first row of seats 5 (driver's seat and passenger seat) in the vehicle interior and near the floor. 8 are provided. The legs 8, 8 can be removed by loosening the screw 8a with a knob. An L-shaped bracket 8b for receiving the bed 1 and a screw 8c with a knob for fixing the bed 1 are provided on the upper portion of the leg portion 8.

With the seat backs of the first row of seats 5, 5 tilted slightly forward, the second row of seats 6 are fully reclined, and the legs 8, 8 are fixed in a predetermined position in a raised state. The bed 1 is placed on the L-shaped brackets 8b, 8b of the two legs 8, 8 and the seating surface of the seat 7 in the third row, and then provided on the upper portions of the two legs 8, 8 for fixing the bed. By tightening the knob screws 8c, 8c, the bed 1
Is set in a predetermined state.

As shown in FIG. 5, a hard plate is attached on the upper surface of one of the four bed bodies 2 as a tray for storing small articles.

According to the vehicle bed 1 configured as described above, since the bed bodies 2 and 2 are made of corrugated cardboard, which is lighter than conventional Rawan materials, the handleability is improved. Further, in this embodiment, since the frame 3 is made of aluminum, the weight is reduced as compared with the conventional steel, and the handling of the bed 1 is also improved in this respect.

Further, each of the bed bodies 2 to 2 has a three-layer structure, and the cores 10a to 10a and the liners 10b to 10b of the core material 10 are arranged vertically and along the width direction W of the bed 1. Accordingly, sufficient rigidity can be exerted against the bending force M in the width direction W applied when a person lays down on the bed 1.

Moreover, the core 11a of the two corrugated cardboard sheets 11, 11 in each of the bed bodies 2 to 2 is
Are arranged in a direction along the longitudinal direction LW of the wavy shape in the width direction W, so that the bed 1 has sufficient rigidity against the bending force M in the width direction. in this way,
By devising the orientation of the core 10a of the core material 10 and the core 11a of the corrugated cardboard sheet 11, the bed body 2 and thus the bed 1 can be provided with necessary rigidity.

Further, the corrugated cardboard does not have the problem that the market price fluctuates greatly unlike the conventional Lauan material, and therefore, it is possible to provide a vehicle bed at a more stable cost than the conventional corrugated cardboard.

Various modifications can be made to the embodiment described above. For example, the orientation of the cores 10a and 11a is arbitrary. That is, the core 10a of the core material 10 may be disposed along the longitudinal direction L of the bed 1 (accordingly, continuously provided along the width direction W of the bed 1). Alternatively, the wavy longitudinal direction LW of the core 11 a may be arranged in a direction along the longitudinal direction L of the bed 1.

The material of the corrugated cardboard, ie, the core 10
a, 11a and liners 10b, 11b may be made of paper or resin. Further, the core material 10 may have a so-called honeycomb shape in which the core 10a is connected in a hexagonal shape without using the liner 10b. The wave shape in the “core of the wave shape that rises and falls in the surface direction of the bed body” described in the claims is a concept including this honeycomb shape. Furthermore, as illustrated, the four bed bodies 2
2 to 1 constitute a set of vehicle beds 1 and 1
One, two, three, or five or more bed bodies 2 to 2 may constitute a set of vehicle beds 1.

Finally, the use form of the bed 1 can be applied to, for example, a form in which the bed 1 is installed using a seat as shown above, for example, a form suspended on a roof, and is widely applied to various other forms of vehicle beds. It is possible.
