Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a folding bed in which one end of the front frame is rotatably connected to the front end of the central frame, and one end of the rear frame is rotatably connected to the rear end of the central frame, so that both the front and rear frames can be folded onto the central frame. It is something.

When this type of folding bed is folded with the mattress or futon placed on it, both ends of the mattress 10 protrude upwards as shown in FIG. 1, making it difficult to fit the bed. 1 in the diagram
is the center frame, 2 is the front frame, and 3 is the rear frame.

The present invention has been made in view of these points, and its purpose is to provide a storage bed in which the upper surface of the central frame automatically sinks when the front and rear frames are folded, so that the pinerest can be accommodated better. .

The present invention will be explained in detail below based on illustrated embodiments. In the figure, reference numeral 1 denotes a central frame framed in the shape of a rectangular parallelepiped, and one end of the upper frame 11 of the front frame 2 and one end of the rear frame 3 are connected to rotating shafts 8 and 9 placed at the tops of the front and rear ends of the central frame 1. Rotatably connected. The front frame 2 is composed of an upper frame 11 and a lower frame 12. One end of the lower frame 12 is rotatably connected to the lower front end of the central frame 1 by a shaft 14. The other end is the upper frame 11 on both ends.
The upper frame 11 is connected to the upper frame 11 by a link 13 rotatably pivoted to the upper frame 11 and the lower frame 12, respectively. Reference numeral 7 denotes a support plate which is rotatable by being supported at one end by a rotating shaft 8 that supports the upper frame 11 of the front frame 1, and this support plate 7 has its lower surface supported by a bar 6. . One end of a first link 4 and a second link 5 are rotatably connected to the bar 6, and the other end of the first link 4 is connected to the lower part of the central frame 1, and the other end of the second link 5 is connected to the front. They are rotatably connected to the lower frame 12 of the frame 2 by shafts 15 and 16, respectively.

When the front frame 2 is raised and folded onto the central frame 1, the bar 6 is rotated and lowered by the second link 5, one end of which rotates about the shaft 14, and the first link 4. For this purpose, the support plate 7 supported by the bar 6 also rotates around the rotating shaft 8 and its other end is lowered.
The pinerest 10 whose central portion is supported also sinks into the central frame 1 when folded. When the front frame 2 is brought down, the bar 6 is raised and the support plate 7 is also returned to its original position. The support plate 7 may have one end connected to the rotating shaft 9 on the side of the rear frame 3. 1
7 is a leg that supports the other end of the rear frame 3. In the front frame 2, the links 13 also serve as legs.

In order to facilitate the rotation of both the front and rear frames 2 and 3 when folded, a compression type frame is used, in which one end of each of the front frame 2 and the rear frame 3 is connected to the lower part of the central frame 1, as shown in FIG. gas spring 1
The other ends of 8 may be connected. 6 and 7 show the skirt 19, headboard 20 and footboard 21 attached. In the figure, h indicates the stroke required for the gas spring 18. Note that the support plate 7 and its related mechanisms are omitted from FIG. 5 onwards.

As described above, in the present invention, as the front frame is folded onto the central frame, the supporting plate on the upper surface of the central frame sinks, and therefore, the central part of the pinerest also sinks into the central frame. The pine tress fits well.

[Brief explanation of the drawing]

FIG. 1 is a schematic front view of a conventional example when folded, FIG. 2 is a perspective view of an embodiment of the present invention, and FIGS.
5 is a front view of another embodiment, and FIGS. 6 and 7 are a plan view and a front view of an example in which a skirt and a headboard are attached to the one shown in FIG. 5. It is a diagram. 1 is a central frame, 2 is a front frame, 3 is a rear frame, 4 is a first link, 5 is a second link, 6 is a bar, 7 is a support plate, 8 and 9 are rotating shafts, 11 is an upper frame, 12 is The lower frame 13 indicates a link.

Claims (1)

[Claims] 1. In a folding bed that is composed of both front and rear frames and a central frame that is located between the two frames and to which one end of each frame is rotatably connected, the front and rear frames are folded onto the central frame, and the upper part of the front frame is One end of the support plate located on the top surface of the central frame is rotatably connected to the rotating shaft that connects the frame and the upper end of the central frame, or the rotating shaft that connects the rear frame and the upper end of the other end of the central frame. The lower end of the link whose upper end is rotatably connected to the upper frame of the frame is rotatably connected to the lower frame of the front frame, and one end of this lower frame can be rotated to the lower end of the front frame of the central frame. The first link has one end pivoted to the lower part of the central frame, and the second link has one end pivoted to the lower frame of the front frame. A folding bed characterized by being freely connected.
