Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a retractable bed device that can be stored in a storage box when not in use.

(Prior Art) Generally, a retractable bed device is known as a bed device that does not occupy a large amount of indoor space when not in use.

Conventionally, as such a retractable bed device, one having a structure as shown in FIG. 11 is known. That is, in the figure, reference numeral 1 denotes a storage box with an open front, and one end of a first frame 2 is pivotally attached to the middle of both inner surfaces of the storage box 1 by a support shaft 3. One end of a connecting member 4 is pivotally attached to the other end of the first frame 2 . One end of a second frame 5 is pivotally connected to the other end of the connecting member 4. Further, an intermediate leg 6 is foldably provided at the other end of the first frame 2, and a front leg 7 is foldably provided at the other end of the second frame 5. The first and second frames 2.5 are supported horizontally by the intermediate legs 6 and front legs 7 when unfolded as shown by chain lines in the same figure, and when folded and stored in the storage box 1, the connecting members 4 They are held parallel to each other at predetermined intervals. That is, since a foldable pinerest (not shown) is placed on the first and second frames 2.5,
When the first and second frames 2.5 are folded, they must be separated by a predetermined distance.

(Problem to be Solved by the Invention) If the first and second frames 2.5 are separated from each other in this way, when they are unfolded horizontally or when they are stored from the unfolded state, the second One end and the other end of the frame 5 move in an arc with the support shaft 3 as a fulcrum, as shown by curves a and b. Therefore, the storage box 1 must be made large enough to allow circular arc movement between one end and the other end of the second frame 5, so the storage box 1 must be connected to the first and second frames 2.
The disadvantage was that it had to be larger than necessary to accommodate 5.

The object of this invention is to provide a retractable bed device that does not require a storage box to be unnecessarily large.

[Summary of the invention]

The present invention includes a storage box with an open front, a first frame supported at the middle part of both inner surfaces of the storage box, one end of which is rotatable and slidable downward; The second frame is pivotally connected to one end of the first frame and the other end is pivotally connected to the bottom of the storage box to prevent one end of the second frame from sliding downward when the first frame is laid down horizontally. a link, and a connection in which one end is pivotally attached to the other end of the first frame and one end of the second frame is pivotally attached to the other end, and the second frame is foldably connected to the first frame. a member, an intermediate leg that is foldably connected to the other end of the first frame and horizontally supports the first frame, and an intermediate leg that is foldably provided to the other end of the second frame and supports the second frame. and horizontally supporting front legs. When the first frame is rotated, its fulcrum slides in the vertical direction.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 10. The retractable bed device shown in FIG. 1 includes a storage box 11 with an open front.

As shown in FIG. 3, guide members 12 (only one is shown) are provided along the vertical direction in the middle of both inner surfaces of the storage box 11, and a slider 13 is provided in the guide members 12 so as to be freely slidable. It is being One end of a first frame 14 is pivotally attached to the slider 3 by a support shaft 15. As shown in FIG.

Further, one end of a link 16 is pivotally attached to a portion of one end of the first frame 14 that is closer to the other end than the portion pivotally attached to the slider 13 . The other end of this link 16 is connected to the lower end of the storage box 11 at tK i5.

Further, one end of the intermediate leg 17 is rotatably connected to the other end of the first frame 14 . As shown in FIGS. 6 and 7, a pin 18 is protruded from one end of the intermediate leg 17, and this pin 1B comes into contact with the first frame 14 when the intermediate leg 17 is rotated by a predetermined angle. The intermediate leg 17 is designed to contact the intermediate leg 17 and prevent it from rotating any further. Further, one end of a stay 19 is pivotally attached to a midway portion of the link 16. The other end of this stay 19 is pivotally attached to one end of the intermediate leg 17. Therefore, when the first frame 14 is rotated from the horizontal state shown in FIG. 1 to the vertical state, the intermediate leg 17 is folded by the link 16 and the stay 19 as shown in FIG. It has become.

One end of a connecting member 21 is pivotally attached to the other end of the first frame 14, and one end of a second frame 22 is pivotally attached to the other end of this connecting member 21.

One end of a front leg 23 is pivotally attached to the other end of the second frame 22. As shown in FIG. 9, this front leg 23 is prevented from rotating beyond a predetermined angle by a stopper 24 provided near its pivot end. Further, the connecting member 21 has a hollow-shaped cross section, and both ends thereof are formed with a notch 25 by removing the intermediate side thereof, and the first and second frames are inserted into the notch 25 at the location of the notch 25. 14.22 is highlighted. Therefore, the first and second frames 14.22 can now be rotated from a straight line to an angle of about 90 degrees with respect to the connecting member 21, as shown in FIG. ing. In addition, the stay 19
A bent portion 26 is formed at the other end, and this bent portion 26 comes into contact with the lower surface of the connecting member 21 as shown in FIG. 7 when the first and second frames 14.22 are unfolded horizontally. This contact prevents the connecting member 21 from rotating in the direction of the arrow.

Further, end members 27 are provided at one end of the first frame 14 and the other end of the second frame 22, respectively, so as to protrude toward the upper surface side of each frame. These end members 2
7 is for preventing the bendable pinerest 28 placed on the first and second frames 14.22 from shifting, and a hook 29 is pivotally attached to one end member 27. There is.

This hook 29 engages with the other end member 27 when the pair of frames 14.22 are folded as shown in FIG.
These pairs of frames are held in a folded state.

Note that a storage section 31 is formed on the back side of the storage box 11. One end portion of a top plate 32 forming a table is pivotally attached to this storage portion 31.

A leg 33 is pivotally attached to the lower surface of the other end of the top plate 32.

The legs 33 are held substantially perpendicular to the top plate 32. Therefore, the table folded and stored in the storage section 31 as shown in FIG. 1 can be unfolded as shown in FIG. 10. Further, a shelf board 33 is pivotally mounted above the table.

A container 34 is pivotally attached to one side of the shelf board 33.

Therefore, the shelf board 33 is changed from the state shown in FIG.
By rotating it as shown in Figure 0, the container 34 can be used.

In the retractable bed device having such a structure, the first,
In order to deploy the second frames 14.22 as shown in FIG. 1, these frames 14.22 are moved in the direction shown by the arrow in FIG. 15 as a fulcrum. Then, in response to the rotation of the first frame 14, the link 16 falls down in the direction shown by the arrow in FIG. . When the support shaft 15 slides in the upward direction, the second
The trajectory of the X point at the lower end of the frame 22 moves from the rear to the front in the depth direction of the storage box 11. Therefore, in the stored state shown in FIG. 10, even if the distance between the second frame 22 and the inner surface of the back of the storage box 11 is small, the point 1. The second frame 14.22 can be rotated in the direction of collapse. In other words, the depth dimension of the storage box 11 can be reduced. At this time, the Y point at the upper end of the second frame 22 will rotate while rising, but in the rising process, the Y point will come out of the storage box 11. Even if a large gap is not secured between the above Y point and the upper inner surface of the storage box 11, -
1-27 points do not collide with the inner surface. In other words,
By lowering the frame 14.22, the support shaft 15 is
Even if the storage box 11 has a structure in which the storage box 11 rises, there is no need to increase the height dimension of the storage box 11. In this way, when the first frame 14 is laid down until it becomes horizontal, the stay 19 is pushed in the direction of the arrow by the rotation of the link 16, so that the intermediate leg 17 is raised, and the first frame 14 will be supported. Next, by removing the hooks 29 of the second frame 22 shown by the chain line in the same figure and deploying it as shown by the solid line, the front legs 23 are raised.
The frame 22 can be supported in a horizontal state with the first frame 14.

Next, store each opened frame 14.22 in storage box 1.
1, the second frame 22 is folded in the opposite direction to the unfolded state and is connected to the first frame 14 with the hook 29 in a non-deployable manner. It is rotated into the storage box 11 while being rotated as follows. Then, as the link 16 rotates in the opposite direction to when it is deployed, the link 16 and the first frame 14
Since the pivot point of the first frame 14 approaches the pivot point of the first frame 14, the support shaft 15 slides downward along the guide member 12 together with the slider 13. Therefore, since the trajectory of point Y shown in FIGS. 1 and 10 also falls downward, the rotation radius R of point Y in FIG.
Even if the frame is larger than the dimension between the support shaft 15 and the upper inner surface of the storage box 11, these frames can be stored in the storage box 11. In other words, the height of the storage box 11 can be reduced.

(Effects of the Invention) As described above, the present invention supports one end of the first frame in the middle part of both inner surfaces of the storage box so as to be rotatable and slidable in the vertical direction. When rotating in the direction of lodging, one end thereof rises, and when rotating in the direction of standing up, it descends. therefore,
The second frame, which is folded parallel to and spaced apart from the frame of TS1 through a connecting member, has one end located at its lower end as a trajectory away from the rear inner surface of the storage box when it is collapsed, and the other end when it is upright. Since the locus is away from the inner surface of the upper part of the storage box, it has the advantage that the storage box can be made smaller than the conventional one.
