Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an improvement in a storage bed device in which the bed is laterally rotated and stored in an upright position within a cabinet.

[Prior art and its problems]

BACKGROUND ART Various types of storage beds have been devised in the past, which have a structure that allows beds that occupy a large floor surface area to be easily stored, and which make effective use of a narrow room. These storage beds usually have a cabinet erected parallel to the wall, and the bed is rotated laterally and stored in the cabinet in an upright position. When the bed was stored, it took a lot of effort to store the leg plate attached to the bed, and the appearance was unsatisfactory in terms of design, so it was not popular as an indoor furniture item.

FIGS. 4 to 6 illustrate a storage bed provided by Japanese Utility Model Publication No. 3071/1983 as an idea to improve the above-mentioned drawbacks of the conventional art.

In FIGS. 4 and 5, the bed main body 1 is pivotally supported at both ends of one side below the opening of the cabinet 2, pivoted upward about this pivot support as a fulcrum, and stored in the cabinet 2. At the lower end of the opening of the cabinet 2, there is a fixed leg plate 3 that is integrated with the cabinet 2. This leg plate 3 acts as one leg when the bed main body 1 is horizontally expanded, and also serves as a leg body of the cabinet 2 when it is stored. This will be the protective device plate at the bottom end.

In FIG. 6, a fixing rod 6 is attached to the inner surface of the leg plate 3.
is fixed, and connected to this fixed rod 6, the leg plate 3
The other end of the link 7, which passes through the bed body 1 parallel to the inner surface of the bed body 1, is connected to a fixing rod 8 fixed to a rotating leg plate 4 which acts as a leg on the other side of the bed body 1, and when the bed is expanded. The leg plate 4 rotates and the bed 1
It is configured to be perpendicular to the frame 5 of the bed, and to support the bed body 1 together with the legs 3 on the floor surface. The legs 4 serve as decorative plates for the upper part of the cabinet 2 when the bed is stored.

In the above-mentioned storage bed, when the bed is stored, it does not require any effort to store the leg plate, and the objective of the improvement has been achieved. However, even in this improved storage bed, when the leg plate 4 is folded when the bed is stored, it protrudes long and horizontally from the surface of the frame 5 together with the leg plate 3, which not only makes the appearance unsightly, but also causes the leg plate 4 to be folded over the link device. Since it is fixed to the fixed rod 8 and rotates, it is not strong enough and there are problems with stability and durability. In particular, since there is no auxiliary device to support the weight of the bed when storing or unfolding the bed, there is a drawback that a considerable amount of human power is required to rotate the bed.

[Purpose of invention]

This invention was developed to solve the above-mentioned problems with conventional retractable beds.The bed looks good after being retracted, has smooth rotation, is structurally strong, and can be operated with light human power. The purpose is to provide a storage bed that can be used.

[Structure of the idea]

The storage bed device according to the present invention connects both ends of one side of the bed main body and both ends of one side of a bed frame provided parallel to the back surface of the bed main body to a bed storage cabinet with an open front surface where these ends face each other. The bed body is rotatably supported on the inner wall surface of each end thereof, and both ends of the other side of the bed body and both ends of the other side of the bed frame are connected to the two axis supports to form vertices of a parallelogram. A balancer is rotatably connected to the bed by a connecting member, and a leg plate that becomes the leg of the bed body when the bed is horizontally expanded is fixed to the connecting member, and a balancer is provided between both ends of one side of the bed body and the inner wall of the end of the cabinet. The above object is achieved by attaching and configuring the device.

[Example of idea]

An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

A bed is provided in both ends 12 on one side of the bed body 11 and on the back surface of the bed body 11 in parallel with the bed body 11, and has a length in one direction that is longer than the length of the bed body 11 in the same direction. Both end portions 15 on one side of the angle member 14 fixed to the bed frame 13 formed short are pivoted to the inner wall surface 17 of the end portion of the bed storage cabinet 16 with an open front, which these end portions 12 and 15 face. Freely pivoted. The pivot points 12 and 15 are connected to the bed body 11.
In the case of the bed frame 13, a bending fitting 18 firmly attached to the side surface of the bed body 11 and a bending fitting 19 firmly attached to the end inner wall surface 17 of the cabinet 16 are used.
It is formed by rotatably engaging the bending fitting 20 firmly attached to the bed frame 13 and the angle member 14 fixed to the bed frame 13, respectively.

Both ends 22 on the other side of the angle member 14 provided on the bed frame 13 so as to protrude toward the other end than the bed frame 13 are rotatably supported by a substantially triangular connecting member 23, respectively. The pivot points 21 and 22 connect the bending fitting 24 and the connecting member 23 firmly attached to the side surface of the bed main body 11 in the bed main body 11, and the connecting member 23 and the bed frame 1 in the bed frame 13.
It is formed by rotatably engaging the angle members 14 fixed to the angle members 3 and 3, respectively. Furthermore,
The pivot points 12, 15, 21, and 22 are each formed to be a vertex of a parallelogram, as shown by a dashed line 25.

The bed body 11 is attached to a portion corresponding to the bottom of the connecting member 23.
A leg plate 26, which is made of the same material and has the same thickness as the bed frame 13, is firmly attached to the bed frame 13. When the bed is stored, the leg plate 26, which is held in this state, rotates outward of the bed frame 13 about the pivot point 21, and is in a state parallel to the back surface of the bed body and flush with the bed frame 13. The bed storage cabinet 16 is housed in the open front side of the bed storage cabinet 16, and the open front surface of the bed storage cabinet 16 is closed with the bed frame 13.

As in the above configuration, the four axes 12, 15, 21
and 22 are each firmly supported by a shaft, and unlike conventional bed devices, a link device consisting of a fixed rod and a long link is not used much, so the operation is smooth and the structure is solid. Therefore, it has excellent stability and durability. In addition, when the bed is stored, the leg plate 26 and the bed frame 1
3, and there is no protrusion on the surface of the bed frame 13 unlike in conventional bed devices, so the appearance is extremely good.

Next, the fulcrum 2 at both ends of one side of the bed body 11 is
7 and a fulcrum 28 on the inner wall surface 17 of the end portion of the cabinet 16, a balancer 29 is rotatably mounted by pivot fittings 30 and 31, respectively. This balancer 29 is designed to solve the drawbacks of conventional bed devices in which the total weight of the bed becomes a load when the bed is stored or expanded, and requires a large amount of human power to rotate the bed. It consists of a conventionally known construction having a cylinder and a rod slidably moving within the cylinder, and is designed to balance the total weight of the bed.

In addition, the reference numeral 32 in FIGS. 1 and 2 indicates the bed body 1.
1 is a pine tress placed on top of the pine tree.

[Effects of the invention] As described above, the retractable bed device according to this invention has a flat plate shape and a length in one direction that is provided at both ends of one side of the bed main body and parallel to the back surface of the bed main body. Both ends of one side of the bed frame, which is formed to be shorter than the length of the main body in the same direction, are rotatably supported on the inner wall surface of the opposite end of the bed storage cabinet having an open front. , both ends of the other side of the bed body and both ends of the other side of the bed frame are rotatably connected by a connecting member so as to form the vertices of a parallelogram together with the biaxial fulcrums; A leg plate formed of the same material and the same thickness as the bed frame, which becomes the legs of the bed body when the bed is horizontally expanded, is fixed to this connecting member, and the leg plate is formed of the same material and the same thickness as the bed frame, and connects both ends of one side of the bed body and the inner wall surface of the end of the cabinet. Since a balancer is installed in between, the bed rotation is extremely smooth and the structure is solid, compared to conventional bed devices that use a link device consisting of a fixed rod and a long link. Therefore, it has the effect of improving stability and durability.

In addition, the leg plate, which is held perpendicular to the bed main body when the bed is horizontally deployed, is held parallel to the back surface of the bed main body and flush with the bed frame when the bed is stored, so that the bed storage cabinet The cabinet is stored in the open front of the cabinet, and the open front of the cabinet is closed with the bed frame, so there is no protrusion on the surface of the bed frame unlike in conventional bed devices, resulting in an extremely good appearance. There is.

Furthermore, unlike the conventional bed which requires a large amount of human power to rotate the bed, by installing a balancer, the bed can be retracted or expanded with light human power.
