Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a sofa-bed.

[Prior Art and Problems] In the sofa-beds currently available on the market, the bed section is divided into two halves centered on the longitudinal center plane. On the other hand, the half day is installed horizontally,
When used in bed mode, it provides a part of the bed surface, and when used in sofa mode, it functions as a sofa seat.

The other half is tiltable and forms the remainder of the horizontal sleeping surface when used as a bed, and functions as the backrest of the sofa when used as a sofa.

The conversion from bed to sofa (or vice versa) is carried out by tilting the other half.

When such a sofa-bed is used in bed mode, sheets, blankets, futons, and other necessary bedding are generally placed on the bed. Therefore, in order to convert a bed into a sofa, the bedding must first be removed from the bed surface and stored in another suitable location. Therefore, the conversion work requires time and effort, and additional storage space is required to store the removed bedding.

[Object of the Invention] One object of the present invention is to provide a bed that can be easily converted from a bed to a sofa (or vice versa) while leaving the existing bedding intact. Our goal is to provide a sofa-bed.

Another object of the present invention is to provide a sofa-bed that can be quickly converted as needed even in an emergency such as when unexpected guests arrive.

In another aspect, it is an object of the present invention to provide a sofa-bed that allows the conversion to be performed easily without removing the bedding from the bed.

In yet another aspect, it is an object of the present invention to automatically create a storage space for bedding when used in bed mode, so that the space in the room can be effectively utilized to store bedding and conceal it in a stylish manner. The objective is to provide a sofa-bed that can be used as a sofa.

Another object of the present invention is to provide a sofa that meets the requirements set forth in item 2 = 3.
- To provide a method for using a single-use bed.

Summary of Means and Effects for Solving Problem 1] The sofa-combined bed and the method of using the same of the present invention are such that the bedding storage space required when converting the bed into a sofa is inherent in the sofa-combined bed. It is characterized in that it is automatically formed by elements provided in the.

That is, all or part of the bed section is supported so as to be tiltable between a horizontal position that provides a bed surface and an inclined position that functions as a sofa-backrest, and the bed section (or a tilting section as a part thereof) is ) are used reversely in bed mode and sofa mode. One side of the bed part (or its tilting part) provides a sleeping surface in the horizontal position and the opposite side provides a backrest surface in the tilted position. A sofa seat is previously arranged below the bed (or its tilting part) when it is in a horizontal position.

When used in the sofa mode, the bedding positioned on the bed section is folded tightly and the bed section (or its tilting section) is tilted to a tilted position. Then, the bedding is automatically stored in the space behind the inclined bed section and is hidden from the user's line of sight. .

In this specification, "r bed surface" is defined to mean a supporting surface on which the body is laid down, and "bedding A" means a sheet, a blanket, a futon, a mattress, or a bed cover. Also, when specifying the front and back of a sofa-bed, the center side of the room is referred to as the front.
The wall side is called the back.

Embodiment 1 The present invention will be described in more detail with reference to the accompanying drawings. 1 to 4 show a first embodiment of the present invention,
Fig. 1 shows the sofa-bed 10 of the present invention set in a state where it can be used as a bed (bed mode), and Fig. 2 shows it converted to a state where it can be used as a sofa (sofa mode). Show the place. 3 and 4 are transverse vertical cross-sectional views of the state shown in FIGS. 1 and 2, respectively.

As can be seen from Figures 1 to 4, sofa-bed 1
0 has a pair of vertical panels 12, 14 which form part of the frame structure of the sofa-bed 10 and also serve as its legs. Furthermore, when used in bed mode, these panels serve as a bedboard and footboard, respectively, depending on the position of the head, and when used in sofa mode, they function as armrests.

As is well known, these panels can be of wood veneer construction or wood composite construction with built-in frames, or they can be formed from less expensive pipe construction.

These vertical panels 12.14 are rigidly connected to each other by a horizontal panel 16 which serves as a sofa seat, forming an integral frame structure with these panels 12.14.16. Connections between vertical and horizontal panels can be made by bolts/nuts, adhesives, welding, or other known connection means. The panels 16 constituting the sofa seat, like the vertical panels 12.14, can be of wooden or pipe construction. In the embodiment shown, the upper surface of the panel 16 is provided with a cushion 18 covered with a skin, which together provide a cushion for the sofa.
Although forming a seat, the cushion is not essential in achieving the objectives of the invention.

This can best be seen from FIGS. 3 and 11. l: On the vertical panels 12 and 14, the tilting panel 20 is attached to the horizontal pivot I to the axis 22 slightly above the sofa seat 16.
It is supported in a tiltable manner by a holder, and can be rotated between a horizontal position (FIGS. 1 and 3) and an inclined position (FIGS. 2 and 4). In the bed mode of FIGS. 1 and 3, this horizontally positioned tilting panel 20 functions as a bed on which to lie, its two sides providing a sleeping surface. Also, in the sofa mode of FIGS. 2 and 4, the slanted panel 20 acts as a backrest for the sofa. For this reason, it is preferable to provide a cushion 24 covered with skin on the front surface of the upper part of the panel 20 that serves as the backrest.

The bed portion, ie, the tilting panel 20, can be made of a wooden veneer structure or a wooden composite structure, and can also be provided with springs and cushions. However, in the case of a children's sofa-bed, it would be cheaper to suspend a network of spring steel strips on a pipe frame.

The pivot shaft 22 may be formed as one long shaft or split into two shafts, and may be mounted in bearings (
(not shown) may be provided. Needless to say, the position of the pivot 22 must be related to the width of the bed section 20 and the seat section 16 so that the inclination angle and height of the backrest are appropriate and the bed section 20 can be pivoted. . As shown in FIG. 3, when the pivot 22 is positioned to the N right of the widthwise center of the bed section 20, the angle formed by the seat section 16 and the backrest 20 in the sofa mode becomes larger than a right angle. (Fig. 4), you can take a comfortable posture. When the bed section 20 is tilted,
The lower portion of the bed portion 20 abuts against the end portion 26 of the seat portion 16, and further rotation thereof is restricted. Therefore, this end 2
6 acts as a collar. It would also be possible to add a backrest angle adjustment mechanism.

In order to lock the bed section 20 in a horizontal position and prevent inadvertent rotation of the bed section 20 in the bed mode, the illustrated embodiment includes a pair of retractable ratchets 2.
8 is embedded in the vertical panel 12.14. In place of the ratchet 28, a locking mechanism such as a pin or other locking mechanism may be used.

As shown in FIGS. 3 and 4, this sofa-bed 10 is generally placed along a wall 30 of a room. In the bed mode shown in FIGS. 1 and 3, the bed section 20 is covered with sheets, blankets, futons, and other bedding 32. A buckled belt 34 (FIG. 1) may be used to secure bedding 32 to bed portion 20 if desired. Instead of the belt, other fastening means may be provided to the net 1, or the sheet or blanket itself may be used for fixation.

To convert this sofa-bed into a sofa, simply fix the bedding 32 with the buckled belt 34, release the radiators 1 to 28, and firmly rotate the bed section 20 together with the bedding 32. good. By doing so, the bedding will not fall off the bed part 20, and the space 36 formed between the bed part 20, which has now become a backrest, and the wall 30.
It is stored neatly in the. Therefore, when converting to a sofa, there is no need to remove the bedding and store it in a closet or the like. In the sofa mode, the space 36 is a so-called dead space, and this space is used to store bedding, so the space in the room can be used effectively. Also, in sofa mode, bedding 3
2 is located behind the backrest (bed part) 20,
It is shielded from the view of users and visitors, and is considered to have a very good appearance.

5 and 6 are sectional views similar to FIGS. 3 and 4, respectively, showing a sofa-bed according to another embodiment of the present invention. The main difference from the first embodiment is the bed section 40.
is folded in half. Other parts can substantially have the same configuration as the first embodiment. Common components are indicated by the same reference numerals and detailed descriptions are omitted.

Referring to FIGS. 5 and 6, the bed section 40 that provides a sleeping surface extends along the center line of W? , + bed section 4
2 and a tilting bed section 44, both of which are connected by a hinge 46. The stationary part 42 is rigidly connected to the vertical panel 12.14 and also serves as part of the sofa-bed frame. The stationary portion 42 also serves to define the lower limit of the bedding storage space 36.

The tilting portion 44 constitutes a part of the bed surface in the bed mode (FIG. 5), and functions as a backrest in the sofa mode (FIG. 6).

A pair of stops 48 are fixed to the vertical panel 12.14 and are adapted to support the backrest by engaging the tilting portion 44 as a backrest.

When changing from bed mode to sofa mode, by rotating the tilting bed section 44 together with the bedding 32, the bedding 32 will be folded in half and placed in the storage space 36 between the backrest 44 and the wall 30. Easy to store (6th
figure). Therefore, in this second embodiment, there is no need for a belt or the like for fixing the bedclothes.

7 and 8 show two further embodiments of the present invention. From the viewpoint of tilting the bed section and bedding storage, the embodiment of FIG. 7 is similar to that shown in FIGS. 5 and 6. The embodiment shown in FIG. 8 corresponds to the first embodiment shown in FIGS. 1 to 4. The embodiments shown in Fig. 7 and Fig. 8 are both designed to reduce weight and simplify the structure, and a part of the frame uses a pipe structure, and the bed part and sofa seat part are made of a pipe structure. is characterized by its simple structure. Furthermore, compared to the first and second embodiments, the bed and sofa seat are made thinner, so the difference in height between the bed surface and the sofa seat is smaller.

Referring to FIG. 7, the sofa-bed 50 has a pair of bent pipe structures 52, 54,
It is formed by welding together two pairs of connecting members 56 and 58 made of angle iron or the like. As is clear from the drawings, the pipe structures 52, 54 also serve as the legs of the sofa-bed. The sofa seat part 60 and the stationary part 62 of the bed part are formed by, for example, pasting a thin cushion made of foam material or the like on a bottom plate (not shown) made of plywood or the like, and covering it with a skin made of woven fabric or the like. can do. The tilting part 64 of the bed part is made of plywood with both sides covered with cushions and a skin, and the hinge 46 in FIG.
It is tiltably connected to the stationary part 62 by a hinge (not shown) similar to that shown in FIG.

A stop 66 is welded to each pipe structure 52,54.

The mode of use of the embodiment shown in FIG. 7 is similar to that of the embodiments shown in FIGS. 5 and 6, and by making the tilting portion 64 horizontal, it can be used as a bed. Further, when the tilting part 64 is tilted until it comes into contact with the stopper 66 as shown, the sofa mode is entered, and the bedding will be stored behind the tilting part 64 as in the case of FIG.

Referring to FIG. 8, components common to those in FIG. 7 are indicated by the same reference numerals, and explanations thereof will be omitted. In the sofa-bed 70 shown in FIG. 8, the entire bed portion 72 is tiltable, similar to the embodiments shown in FIGS. 1 to 4. For this purpose, cross members 74 and 76 are welded to the pipe structures 52 and 54, respectively, so that a pivot 80 extending from the bed portion 72 is rotatably supported. The manner of use of the embodiment of FIG. 8 is similar to that described above for the embodiment of FIGS. 1-4.

The embodiments of FIGS. 7 and 8 may have the advantage of being lightweight and inexpensive to manufacture.

Yes, they also belong to the present invention. In particular, although the vertical panels 12, ]4, the seat 16, or the tilting bed 44 have been described as forming part of the frame of the sofa-bed, it is also possible to provide a separate frame. Also, the sofa-bed may have separate legs,
The legs may be omitted. Beds and sofa seats can be provided with various types of cushions.

[Effect of the invention] The effects of the present invention have been explained throughout the following sections.

It should be noted here that the basic effect is that the bed can be converted into a sofa without removing or removing the bedding elsewhere. Therefore, conversion work can be carried out easily and quickly. It is especially suitable in case of unexpected guests. This is particularly effective in children's rooms that often do not have a dedicated sofa.

From another point of view, since the bedding is stored using the dead space, the space in the room can be used effectively, and the need for a separate bedding storage space can be omitted. Further, even if a normal storage space such as a closet is permanently installed, the size can be reduced. These are extremely useful in today's world where housing conditions are getting worse and worse.

Although various effects of the present invention have been described in this column in accordance with laws and regulations, it should be noted that the invention does not fall outside the technical scope of the present invention unless all such effects are simultaneously enjoyed.
